double drive plasma cutting machine

double drive plasma cutting machine Coordinate CNC cutting machine is one of the modern cutting equipment in the cutting industry. With its good man-machine dialogue operation interface, powerful auxiliary support function, and with the support of automatic programming, nesting and other software systems, the coordinate CNC cutting machine has played an important role in production, and has become the choice of cutting processing for manufacturing enterprises in China Choose. C. At present, thermal cutting is widely used in the construction machinery industry. Flame, plasma and laser cutting technologies are all thermal h beam welding line cutting. The technical and economic comparison of the three cutting technologies is shown in the table below. 4. In the whole cutting process of fiber line laser cutting machine, the focus position deviation is produced in the whole process of laser cutting of sample 02. Many factors change the relative position between the focus point and the surface layer of the processed object, which is also related to the surface gloss of the processed product. The clamping method of workpiece, the geometric deviation of NC lathe and the long-term load of NC lathe all result in deformation. In the production process, the thermal deformation of the workpiece will cause the error between the laser focus position and the idealized given position (program writing part). For this kind of random deviation, it is difficult to avoid. Only according to the on-line monitoring and control, the deviation can be reduced, and then the working precision of the fiber line laser cutting machine can be improved. The supplier of Tianjin desktop plasma cutting machine 2. Once the operator leaves the machine for a long time, the power should be turned off to prevent non specialistOperator operation. 3. When the operator is using the machine, pay attention to observe whether there is lubricating oil on the surface of the horizontal and longitudinal guide rails and rack, so as to keep them well lubricated! Stage 2: Weekly beauty and beauty 1. Clean the CNC cutting machine comprehensively every week, clean the horizontal and longitudinal guide rails and transmission gear teeth, and add lubricating oil. 2. Check whether the rail scrapers in the transverse and longitudinal directions work normally. If not, replace them in time. 5. Low operation cost: the power consumption of the whole machine is only 20-30% of the same type of CO2 laser cutting machine; 6. Low maintenance cost: optical fiber transmission, no need for reflection lens; basically free of maintenance, can save a lot of maintenance costs; 7. Simple operation: optical fiber transmission, no need to adjust the optical path; after simple training, the machine can be operated and used, which is very convenient. Disadvantages: at present, most of the core key technologies of fiber lasers are controlled by one or two manufacturers in Europe and the United States, so most of the machines are expensive, most of them are more than 1.5 million yuan, and the low-power ones are about 500000 yuan. Due to the fine fiber cutting seam and huge gas consumption (especially in nitrogen cutting), the fiber laser cutting machine is relatively difficult to cut When cutting aluminum plate, copper plate and other high reflection materials, the speed becomes not obvious when cutting 30 mm thick plate. with the application of fiber laser generator more and more widely, its professional knowledge has been received by a large number of peopleBy contrast, the market sales of fiber line laser cutting are also slowly expanding. Naturally, all this is due to the perfect application of key technologies, which improves the technical level of mechanical processing and manufacturing companies, improves the economic benefits, and then pays more attention to the application stores of fiber laser cutting machines. A new explanation is given for the market share of the current fiber line laser cutting machine. Looking at the sales market of laser industry in 2012 and 2014, the overall growth rate of the laser cutting machine market is above 10, so how can the fiber laser cutting machine manufacturers do their own product positioning and achieve greater development? Technical and economic comparison table: the flame cutting machine has large cutting deformation, low cutting speed, preheating before cutting, which takes a long time. However, multiple cutting torches can be used to cut at the same time, and the service life of consumable parts is long. Although plasma cutting can cut all metal plates and many non-metallic materials, the cutting speed can reach 10 m / min, which is 10 times of that of flame cutting. However, the width of the cut is large. Except for the thin plate, the cutting surface is easy to "collapse", and the medium and heavy plate can be cut economically. Although the price of laser cutting machine is expensive, it can realize high-speed and high-precision cutting for thin and medium plate, and can realize unmanned operation at the same time. Beijing tube sheet cutting machine price service assured environmental control plasma arc cutting process will produce noise, smoke, arc light and metal vapor, which will cause pollution to the environment, especially in high current cutting or cutting non-ferrous metals. How many are there nowIn addition to water recompression plasma arc cutting, surface cutting and underwater cutting are also effective methods to reduce environmental pollution. A water storage tank is needed for cutting on water surface. The working table of the water storage tank for placing workpieces is composed of a number of orderly arranged pointed steel members, which support the workpiece to be cut on the horizontal plane. When cutting, the plasma arc is surrounded by a layer of water curtain. In order to maintain continuous water curtain, a circulating water pump is needed to pump water from the storage tank and then into the shear strength. When water is ejected from the cutting force, a water curtain is formed around the plasma arc. This kind of water curtain can greatly control the environmental damage caused by the pollutants such as noise, smoke, arc light and metal vapor in the cutting process. The water flow rate required by this method is 55 ~ 75L / min. There are many kinds of joint forms of laser cutting machine composite welding technology, such as butt welding, steel bar lap welding, overlap welding (wave soldering), steel bar lap connection composition and so on. Butt welding is a very common way of connector, which is widely used for the connection between plates. From the perspective of structural mechanics, it is an ideal form of joint. It has good bearing capacity, small stress, and can bear large static load or load. It is a common joint form in welding structure. However, this kind of method has strict regulations on the heat input in the whole welding process, and the general welding method is very easy to lead to the deformation of prefabricated components due to high heat bonding, while the thermal output of laser low temperature plasma hybrid welding technology is overallIt is not easy to cause deformation and has high performance price ratio. The gap adaptability is several times larger than that of single beam laser welding. It is suitable for the connection weld of metal sheet. 4. Water jet cutting, as a precision machining method of industrial products, is characterized by no or little heat release, no thermal deformation, no gas or steam emission. The research of this cutting technology began in the 1960s. After more than 20 years of research and development abroad, a high-pressure water jet cutting equipment has been manufactured, which can cut various metals and ceramics. High pressure abrasive water jet cutting equipment was developed and used in production in China in 1990s. At present, most of the water jet cutting equipment is mainly used in the cutting of non-metallic plates. 5. When working, start the main motor first, and then press the work advance button. When cutting, because the rocks are mostly irregular shapes, the feed speed should be slow, and it can be slightly faster after all the blade edges enter the rock sample. 6. When the cutter moves along the worktable to the terminal, it can automatically back to the starting end and stop moving automatically. If you need to go back in the process of work, press the fast backward button on the console. If you need to move forward in fast backward, you can also feed by pressing the work advance button. The cutter can stop moving by pressing the stop button whether feeding or withdrawingMove. When working, if it is found that the cutter is far away from the rock sample, press the fast forward button (hold it down) or jog the fast forward button. When the blade approaches the rock sample, release the button. Then press the work in button to cut normally. This can shorten the feed assist time. The feed transmission of the machine is shown in Fig. 3. The cutting machine is divided into metal cutting machine and non-metal cutting machine. The cutting machine mainly uses CO2 laser cutting machine. Because the wavelength is about 10600, it is suitable for cutting non-metallic materials, while cutting metal materials is still using optical fiber or YAG equipment, because their wavelength is between 1060 and 1070. Metal materials have the problem of energy absorption at this wavelength. If you can use CO2 equipment, it's totally energy-based melting. In the past, laser processing equipment has the limitation of single processing form. A kind of laser equipment is only applied to a certain process, such as cutting is only cutting, welding is only welding, or can only be applied to specific processing materials. Therefore, some sheet metal processing plants often need to invest a lot of different types of laser equipment, and need to support different types of cooling equipment, such as special S & a company's cutting chiller, welding chiller, spindle chiller. Hunan cutting machine parts factory deeply ploughs into the market because CNC cutting machine has a very important role in many industries, so we will be more interested in it, want to know what kind of equipment it is, in fact, after in-depth understanding, we will find that it is indeed very good in many aspects. meetWe'll learn about its cooling method. There are two cooling methods for CNC cutting machine: water cooling and air cooling, which can prevent the internal overheating of the cutting machine and reduce the temperature. In terms of cutting principle, it can be divided into contact arc starting and non-contact arc starting. Generally, manual elbow can be used in both ways, and non-contact arc starting mode is widely used in machine use! how to choose gantry type CNC cutting from the perspective of function Cutting machine equipment, is the following small series will be explained to you a selection method. From another point of view, to understand the function of gantry CNC cutting machine is also the basis for improving the use of equipment in the next step. 1. Walking guideway the walking guide rail of gantry type CNC cutting machine will be different according to the type of cutting machine. Generally, the walking guide rail of gantry type CNC cutting machine includes 24kg light rail and 38kg heavy rail, and some small format models can adopt T-shaped guide rail; and like other models, linear guide rail can also be considered. At present, more and more metal laser cutting companies choose gantry cutting machines to carry out production and processing. In the sales market, a variety of gantry cutting machine manufacturers make us confused when choosing and purchasing gantry cutting machines. It is not clear which cutting machine is better to choose. So, before purchasing, do you know the three main products of gantry cutting machineWhat are the advantages of gantry cutting machine? The three main products of gantry cutting machine series are gantry CNC flame cutting machine, gantry CNC low temperature plasma cutting machine and gantry straight CNC cutting machine. Generally, manual plasma arc cutting or automatic cutting operation platform should be equipped with exhaust system software to extract organic waste gas out of the production workshop. However, the discharged organic waste gas still causes environmental pollution to the natural environment. If the environmental pollution caused exceeds the allowable standard in China, dust filter equipment should be upgraded. The main harmful factors of plasma arc cutting are harmful substances, metal dust, noise, electro-optic (UV) radiation source, high frequency magnetic field, etc. The main risk source is high voltage electric shock. Therefore, plasma arc cutting must attach great importance to the safety and protection work. Heilongjiang heavy gantry CNC cutting machine manufacturers 1, manufacturers must do a good job in product positioning. In a market to do well, make a brand, accumulate rich experience. Such as sheet metal cutting market, automobile market, etc. 2、 Manufacturers themselves must do a good job in market positioning. On the one hand, the profits in the market are high and the vacuum period is long; on the other hand, the technology of most manufacturers can not fully meet the market demand. But enterprises must do a good job in this positioning, looking for a breakthrough, specializing in development. 3、 Due to the fierce competition in the small power market of fiber laser cutting machine, it is necessary to do a good job in the core technology and after-sales service, and improve the mechanical power through technical developmentNew market, and maintain customers, through the word of mouth brand model to develop new customers. CNC laser cutting machine has the characteristics of fast cutting speed and high precision. The laser cutting machine is expensive and expensive. It is only suitable for thin plate cutting with high precision requirements. CNC high pressure water jet cutting machine is suitable for cutting any material (metal, nonmetal, composite material), with high cutting accuracy, no thermal deformation and environmental protection Methods. Its disadvantages lie in low cutting speed, low efficiency and high cutting cost. Other CNC cutting machines: including CNC pipe cutting machine, CNC section steel cutting machine, CNC groove cutting machine, CNC woodworking cutting machine. These special cutting equipment are mainly used in various special profile CNC cutting, and there are few manufacturers in the market. 3. CNC cutting machine: mobile phone software CNC machine tool cutting machine, also known as electronic computer numerical control machine tool cutting machine, more powerful, the application of excellent contemporary electronic information technology, including windows system software, sharing WiFi and communication, programming nesting management methods, etc. There are two key ways of composition: A. one is composed of industrial computer motion controller cutting mobile phone software. b. One is composed of cutting mobile phone software for CNC machine tools, such as Siemens' SINUMERIK840D, FANUC 0I, etc. The noise can be significantly reduced by placing the workpiece in water for cutting. The results show that when the workpiece is cut in water, the noise is reduced by 22-24db compared with dry cutting. In addition, the noise can be reduced by about 20dB by using the wet curtain cutting torch (the water output of the wet curtain is 70-80l / min). When the cutting current is less than 100A, the noise is low and the damage to the surrounding environment is not great. (5) The safety protection of high frequency magnetic field plasma arc cutting needs to select high frequency oscillator arc ignition. But high frequency can do harm to people. The main measures to avoid are as follows: the selection of arc starting frequency is 20 ~ 60Hz, the high frequency oscillator is equipped with shielding off protective cover, and the product workpiece is reliably grounded; during arc striking, the switching power supply of high frequency oscillator should be immediately and reliably disconnected after the main electrical soliton is ignited; the time should be reduced as far as possible when checking the electric level alignment with high frequency flame. Can laser cutting machine cut wood board? At present, wood cutting is mostly carried out by traditional wood saw blade cutting method, but it will cause a lot of environmental pollution such as sawdust and noise. Using laser to cut wood can not only reduce the noise, but also reduce the cause of sawdust particles, reduce the harm to people. The cross-sectional quality of laser cutting wood is better than that of traditional cutting method. The cutting surface is not smooth, torn or fluffy. The wood texture is not obvious, but only covers a thin carbonization layer. < BR, the plasma cutting machine was used in Anhui flame cutting plantThe basic principle of cutting is the way to produce and process pipe trench on the surface of metal. 7. Carbon arc air gouging: the metal material is melted by the electric arc caused by graphite rod or carbon rod and the product workpiece, and it is scraped away by air compression to complete the production and processing of pipe trench on the metal surface. 8. Profile cutting: the mechanical automatic cutting is carried out by moving the gas cutting torch along a certain steel profile following the tape drive. 9. CNC machine tool cutting: thermal cutting according to the program flow required by data command. 10. Water cutting: thermal cutting carried out in water. 11. Cutting torch: it is a key special tool for oxygen cutting. It can install or replace the cutting nozzle, adjust the gas pressure of heating flame and control the oxygen flow rate of cutting. 12. Cutting mouth: the part of the mouth on a cutting torch. The oxygen flow is cut and the cyclone is mixed. 13. Heating flame: the flame used to heat metal materials around the wound at the beginning and during the whole process of oxygen cutting to make it ignition point. 14. Heating oxygen: the oxygen commonly used for heating flames. With the development trend of decades, CNC cutting has obtained a long-term development trend in laser cutting resources and CNC machine tool management and management system. Laser cutting resources have changed from a single flame resource to a variety of resources (flame, low-temperature plasma, laser, high-pressure jet) laser cutting methods CNC cutting management and management system has been developed from simple performance, complex programming and typing mode, low level of automation technology, to the performance improvement, intelligent system, graphical interface, digital control mode; driverThe management system has also changed from step motor driver, imitation servo motor driver to all word type servo motor driver today. Attention: ① the lens should be gently wiped to avoid damaging the surface coating; ② the lens should be handled with care to prevent falling; ③ the concave surface must be kept downward when installing the focusing lens. 3、 The cleaning of the fan, the long-term use of the fan will make the fan accumulate a lot of solid dust, make the fan produce a lot of noise, and is not conducive to exhaust and odor. When the suction of the fan is insufficient and the smoke exhaust is not smooth, first turn off the power supply, remove the dust from the inlet and outlet pipes of the fan, and then turn the fan upside down and pull out the blades inside until it is clean, and then install the fan.
