High safety factor: no flammable and explosive gas is required, ensuring the safety of life and property. 2. Energy conservation and environmental protection. The welding process will not produce carbon monoxide, carbon dioxide and other harmful gases. Due to the use of electricity, compared with acetylene, gasoline, oxygen, liquefied petroleum gas and other gases, the cost is greatly reduced. 3. Low cost: traditional brazing and welding has low temperature, large thermal radiation, high welding cost, and the risk of explosion. The flame temperature of the plasma brazing machine is controllable, the welding temperature can reach more than 2000 degrees, and the stability is high, which is more than twice the speed of acetylene welding. It can be welded continuously for 12 hours. 4. Convenient to carry: because the whole host weighs only a few kilograms and is small, it does not need an acetylene cylinder or oxygen cylinder, so it is very suitable for working outdoors or in a harsh environment.

Unlike other welding machines, high frequency pipe welding machine has more functions and uses than single welding machine. High frequency pipe welding machine can not only be used for welding various metal materials, but also be used for diathermy, melting, heat treatment and other processes.The high-frequency welding pipe machine is mainly composed of uncoiler, straightening machine, active straightening machine, shear butt welding machine, storage loop, forming and sizing machine, computer flying saw, milling head machine, hydraulic testing machine, blanking roller table, flaw detection equipment, packer, high-frequency DC drive and whole-line electrical appliances.High-frequency pipe welding machine is used to send steel strip of certain specifications into the machine, curl the steel strip into pipe blank through the forming roller, and then use the proximity effect and skin effect of high frequency to quickly heat the pipe edge to the welding temperature, complete the welding under the extrusion pressure of the extrusion roller, and then cool, size and rough straighten the steel pipe of the required specifications.Working principle of high-frequency pipe welding machineFirst of all, in the high-frequency pipe welding machine, a set of unique electronic circuits will convert the low-frequency alternating current (50Hz) input from the power grid into high-frequency alternating current (generally more than 20000Hz). After the high-frequency current acts on the inductive coil (i.e. induction coil), it will be converted into high-frequency magnetic field through the electromagnetic induction principle, and act on the metal objects in the magnetic field; The eddy current effect is used to generate an induced current in direct proportion to the magnetic field strength in a metal object. This eddy current is affected by skin effect. The higher the frequency, the more concentrated it is on the surface of metal objects. When eddy current flows in a metal object, it will generate heat by using the principle of current thermal effect and its internal resistance value. This heat is generated directly inside the object. Therefore, the heating speed is fast and the efficiency is high. It can instantly melt any metal. Heating speed and temperature are controllable. This equipment is especially suitable for heat treatment quenching, annealing, metal diathermal forging, extrusion molding, solder welding, etc.What are the forging applications of high-frequency pipe welding machine? 1. The steel plate is heated and bent. 2. Diathermic forming of standard parts and fasteners. 3. Hardware tools are formed by heating, such as pliers and wrenches. 4. Extrusion of drill pipe taper shank. 5. Steel pipe diathermy forming, such as elbow, etc.What are the precautions for high-frequency pipe welding machine1. Do not start the machine without knowing its structural performance or operating procedures.2. During the working process of the machine, the mold should not be repaired or adjusted.3. When the machine finds serious oil leakage or other abnormal conditions (such as unreliable movement, loud noise, vibration, etc.), it should stop to analyze the causes and try to remove them. It is not allowed to put into production with defects.4. Do not overload or exceed the extreme eccentricity.5. It is forbidden to exceed the limit stroke of the slider, and the height of the mold shall not be less than 600mm.6. The grounding of electrical equipment must be firm and reliable.7. At the end of each day's work: put the slider in the proper position.

1. Upper mold: install the mold on the high-frequency machine, lay the edge material on the bottom, pay attention to the integrity of the mold section and mold, mold adjustment: after the mold is installed, it must be adjusted to the level and the set parameters, pay attention to the same depth on the left and right, not too deep nor too shallow) Press the high-frequency: align the material with the mold, press the presser foot, and double press the power switch.2. High frequency is high frequency wave. The principle of high-frequency pipe welding machine is different from that of ultrasonic. The high-frequency electromagnetic field is used to make the molecules in the material collide violently and generate high temperature, so as to achieve the purpose of welding. Due to the wide range of applications of high-frequency pipe welding machine, there are currently high-frequency plastic welding machine, high-frequency leather plastic welding machine, high-frequency folding machine, high-frequency metal welding casting machine, high-frequency metal heating machine, etc., high-frequency products are more popular, because the high temperature generated by high-frequency electromagnetic field is more conducive to product integration.3. The output power of the tweeter is very high. The cycle rate of the oscillator is 27.12 MHz or 40.68 MHz, which conforms to the frequency band standard. The special electronic circuit of various control devices can avoid operating errors, weld the product as soon as possible, and improve the product yield. The working principle of the high-frequency pipe welding machine is that the dielectric material generates molecular polarization through the high-frequency electric field and is arranged along the direction of the electric field. If the direction changes at a very fast speed due to the high-frequency electric field, the dielectric material will generate heat due to the dielectric loss.4. High frequency pipe welding machine is specialized in producing various general high frequency equipment and four-row manual sliding table welding machine. The high-frequency machine is flexible and convenient to operate, which can improve the output. High-sensitive spark protection device to prevent mold damage can be customized according to customer requirements. The high-frequency machine is suitable for processing the whole roll of products, PVC folding, checker bar, business card holder and other products can be processed in the whole roll. For hard materials, leveling and forming can be completed at one time, bridge breaking can save manpower, improve product accuracy, and high sensitivity spark protection device can prevent damage to the mold.5. The automatic frequency tracking function of the high-frequency pipe welding machine is combined with the frequency polarization protection function, so that the generator of the ultrasonic plastic welding machine is always at a good working frequency. The tuner has a lifting circuit and a suppression circuit. During normal welding, the amplitude can reach 1.5-2 times, which improves the instantaneous welding characteristics, automatically reduces the overload amplitude, keeps the overload continuous, and has good automatic amplitude modulation function.6. Install the electronic tube. A. Open the lower front cover plate and right cover plate of the body. b. Carefully put the high-frequency electronic tube into the resonance cylinder * from the gap behind the machine, and fix it on the mounting base with screws after adjusting the direction. C. Install the filament wire on the filament screw of the electronic tube. When tightening the nut, two suitable wrenches must be used to clamp the upper nut and the lower nut at the same time to prevent the ceramic body on the electronic tube from cracking and the electronic tube from being scrapped. D. Fix the grid copper plate on the grid of the electronic tube with screws and do not loosen it.7. Install the push plate slide rail and place the push plate. First fix the slide rail on the corresponding mounting base of the machine with screws (do not tighten the screws first), then place the push plate on the slide rail (the pulley should block the slide rail), adjust the slide rail to align the push plate with the support plate, so that it can move smoothly and flexibly. Then tighten the rail retaining screws.8. Install the power cord. The power line of the high-frequency pipe welding machine is a five-core cable, including yellow ground wire, brown ground wire and other three ground wires (without phase sequence). To ensure personal safety, the ground wire must be reliably connected.

High-frequency pipe welding machine is a popular product, but many people do not understand its function. First of all, we should know that the high frequency pipe welding machine has a high safety factor, because it does not need flammable and explosive gas when working, which ensures the safety of life and property. No harmful gases such as carbon monoxide and carbon dioxide will be generated during welding. Compared with acetylene, gasoline, oxygen, liquefied petroleum gas and other gases, the cost is greatly reduced due to the use of electricity. Of course, there is also a very important point, that is, low cost: the traditional brazing and welding temperature is low, the heat radiation is large, the cost is high, and there is the risk of explosion. The flame temperature of the high-frequency pipe welding machine is controllable, and the welding temperature can reach more than 2000 degrees, with high stability, which is more than twice the speed of acetylene welding. It can be welded continuously for 12 hours. Another thing is convenient to carry. Because the weight of the whole host is only a few kilograms and its volume is small, there is no need for acetylene cylinder or oxygen cylinder. High frequency pipe welding machine is very suitable for outdoor or harsh environment. Now it can be used for welding metal products, such as towel rack, soap net, bathroom pendant, auto parts, motorcycle parts, metal material wiring terminal, hardware, heating pipe and standard parts.The H-beam welded by high-frequency pipe welding machine has excellent performance. Compared with hot-rolled H-beam, its section modulus and bending strength are higher than hot-rolled H-beam under the same unit weight. In steel structure engineering, the amount of steel used for the same components is greater than that of high-frequency welded H-beam. In steel structure villas, low-rise and low-rise residences, if properly used, its advantages can be fully utilized to achieve the purpose of saving steel and reducing costs. High-efficiency high-frequency welding machine has very reasonable section economy. It is also important to diversify the production varieties of high-frequency pipe welding machines. Because the equipment is mainly used to fuse metals with the same composition, the requirements for the composition of the base metal are relatively loose. It can not only weld ordinary carbon steel, but also alloy steel, stainless steel, Al, Cu, Ni, Ti and other alloys. Because the H-shaped steel produced by high-frequency pipe welding machine is limited by less equipment and has more product specifications. Therefore, it is very popular. Steel makes full use of the skin effect and proximity effect of high-frequency current, so that high-frequency current is highly concentrated in the narrow welding area, and the consumption of base metal removal from the base metal is less in a short time.

Due to the maturity and excellent performance of the forming and welding technology of the high-frequency pipe welding machine, the high-frequency pipe welding machine is widely used in chemical, petrochemical, electric power, construction and other industries. The main function of the equipment is to use it when installing pipelines. There are many pipeline products on the market, and each pipeline has its own characteristics. Pipeline products play an important role in the market and are also products needed in life. When the high-frequency pipe welding machine is developed in the market, it generally has a bright future. High-frequency pipe welding machine can gain a better foothold in the market, and it is also relatively stable. In addition, the wall thickness of pipe making is large, which can meet the requirements of general pipes, and the pipe making accuracy is high. Another thing is stable performance and high output.High-frequency pipe welding machine can be used to weld bimetal composite pipes, such as air conditioning copper pipe and air conditioning copper pipe, air conditioning copper pipe and seamless steel pipe. For welding bimetallic composite pipes. After welding, the shape is beautiful, solid, round, evenly heated, and there is no solder leak or solder leak. The advantages of high frequency pipe welding machine are also very obvious at work, such as high induction heating speed, high efficiency, energy saving and low cost compared with oxygen welding. 3. Small oxidation area. Energy saving and low cost 4. Small oxidation area and beautiful appearance after welding. The heating is uniform, and there is no risk of missing welding or missing welding. In fact, the equipment has high efficiency, fast tooth welding speed, 1-5 seconds per tooth, good repeatability, good repeatability of each tooth, rapid and uniform heating, which can effectively avoid cracking caused by serrated aging and local overheating, and also avoid safety hazards such as missing teeth caused by incomplete fusion in the melting furnace. High-frequency pipe welding machine has high performance and toughness sawtooth woodworking saw blade, which is actually a saw blade that cannot be welded by resistance welding machine, with low power consumption (2-3kw/H).
