Description

Technical Field

[0001] The invention relates to the technical field of steel material processing, in particular to a high-frequency welding machine with a welding slag self-cleaning function. Background Art

[0002] High-frequency welding machine is a device used for welding. High-frequency welding machine is different from other welding machines. Its functions and uses are not just single welding. High-frequency welding machine can not only be used for welding of various metal materials, but also for processes such as heat penetration, smelting, and heat treatment. It has the characteristics of fast heating speed and high efficiency. It can melt any metal object instantly, and the heating speed and temperature are controllable. High-frequency welding machine is particularly suitable for heat treatment quenching, annealing, metal heat penetration forging, extrusion molding, brazing welding, etc. In addition, when using high-frequency welding machine, it has a high safety factor, energy saving and environmental protection. During the welding process, no harmful gases such as carbon monoxide and carbon dioxide are generated. During the processing of steel, it is generally necessary to use a high-frequency welding machine to weld the joints.

[0003] In the prior art, when a high-frequency welding machine is welding steel, metal welding slag will adhere to the welding part, and the welding slag needs to be scraped or brushed off from the surface of the steel by tools such as a scraper or a wire brush. However, the removed welding slag will fall directly to the ground. As the welding slag accumulates more and more, it will adhere to the ground. In order to prevent the accumulated welding slag from affecting the cleaning of the welding slag by the scraper or wire brush, the staff needs to clean it regularly, which increases the workload and is more troublesome. In the cleaning process, it is also easy to get injured accidentally.

[0022] 3.

[0040] according to Figure 1 and Figure 3 As shown, the outer surface of the annular tube 805 is fixedly installed on the outer surface of one of the support platforms 10 away from the nitrogen nozzle 806, and the pushing component 9 includes a reinforcing plate 901.

[0044] according to Figure 4 and Figure 6 - Figure 7As shown, a fixing frame 504 is fixedly installed on the outer surface of one side of the slag removal box 3, and a second forward and reverse motor 503 is fixedly installed on the top of the fixing frame 504. The output end of the second forward and reverse motor 503 is fixedly connected to one end of one of the fixed columns 502.

[0045] The effect achieved by the entire mechanism is as follows: when in use, five support platforms 10 are provided, the outer surface of the hydraulic rod 902 close to the output end is fixedly installed inside the leftmost support platform 10, and the remaining four support platforms 10 are distributed in pairs on both sides of the welding electrode 204, and the steel materials to be welded are placed inside the support platforms 10 respectively, one of which passes through the two perforations 14 and the annular brush 13, and the other passes through the annular tube 805, such as Figure 1As shown, the two steels are then pushed at the same time so that they pass through the inside of the welding electrode 204 together. When one end of the two steels are against each other inside the welding electrode 204, the thrust on the two steels is released. The high-frequency generator 202, the transformer 203 and the welding electrode 204 are electrically connected. The front surface of the welding body 201 is provided with a control button. The liquid pump 403, the solenoid valve 408, the pressure sensor 414, the second forward and reverse motor 503, the first forward and reverse motor 601, the fan 702, the hydraulic rod 902 and the PLC controller 11 are electrically connected. The external power supply of the nitrogen generator 801, the welding assembly 2 and the PLC controller 11 is turned on in advance, the equipment is started, and a high-frequency signal is generated by the high-frequency generator 202. The transformer 203 sends the high-frequency signal. The high-frequency signal generated by the generator 202 is converted into high-voltage and low-current electrical energy, and then the current is transmitted to the welding area through the welding electrode 204. The high-frequency current generates local heating in the welding area, so that the connection between the two steel materials is heated, melted and welded together. The nitrogen generator 801 is started, and the nitrogen is input into the nitrogen pipe 802 through the output end of the nitrogen generator 801, and enters the outlet pipe 804 through the pressure regulator 803, and then enters the inside of the annular pipe 805, and is sprayed out through multiple nitrogen nozzles 806. The multiple nitrogen nozzles 806 are all directed to the welding area, and the nitrogen nozzles 806 are arranged in large numbers to form a ring, so that the nitrogen can be evenly sprayed to the steel welding area. Nitrogen has the characteristic of not easily reacting chemically with steel, which can maintain the welding area Purity, avoiding the presence of oxygen and moisture, reducing oxidation reactions and the generation of welding slag. In addition, the welding area can be quickly cooled, which is helpful to improve the welding speed and welding quality, thereby achieving the effect of reducing the generation of welding slag. The pressure regulator 803 is convenient for adjusting and controlling the flow and pressure of nitrogen. At the same time, the first forward and reverse motor 601 is started through the PLC controller 11, and the bidirectional screw rod 602 is driven to rotate through the output end of the first forward and reverse motor 601. Under the limit of the limit rod 605, the two moving plates 603 are driven to move relative to each other, so that the two triangular scrapers 604 move relative to each other, one of the triangular scrapers 604 is located inside one of the moving plates 603 close to one side, and the other triangular scraper 604 is located inside the other moving plate 603 close to the other side. The two triangular scrapers 604 are staggered and both are relatively long. When the two triangular scrapers 604 come into contact with the outer surface of one of the steel materials, the first forward and reverse motor 601 is automatically paused, so that the two triangular scrapers 604 are attached to the outer surface of the steel material. When the steel materials are welded, the welding assembly 2 is closed, and the hydraulic rod 902 is started by the PLC controller 11 to push the push plate 903 to move, and then the other steel material is pushed toward the slag removal box 3, so that the welding part of the steel material is further moved out from the inside of the welding electrode 204 and into the inside of the slag removal box 3. With the push of the hydraulic rod 902, the welding part of the steel material moves to the triangular scraper 604, and the welding slag at the welding part is scraped off by the triangular scraper 604. At the same time, the fan 702 is started.Air is blown by the fan 702, and the wind is blown into the circulation pipe 704 through the connecting pipe 703, and finally blown out through multiple first blowing nozzles 705 and second blowing nozzles 706. The first blowing nozzle 705 is directed toward the triangular scraper 604 to blow the scraped welding slag off the steel, and the second blowing nozzle 706 is directed toward the front wall and the rear wall of the slag removal box 3 to blow the small welding slag debris adhering to the inner wall of the slag removal box 3 and drop it into the conical slag discharge bucket 406. Part of the welding slag falls downward into the filter frame 409 and the solution pool 407 through the space between the arc-shaped discharge plate 501 and the conical slag discharge bucket 406, and part of the welding slag falls onto the arc-shaped discharge plate 501, and slides down along the arc surface of the arc-shaped discharge plate 501, starting the second forward and reverse The motor 503 drives one of the fixed columns 502 to rotate through the output end of the second forward and reverse motor 503, thereby driving the arc-shaped blanking plate 501 to rotate. The speed of the second forward and reverse motor 503 is set to be slow. Each time it rotates forward 30 degrees, it will automatically reverse 30 degrees. Under the forward and reverse drive of the second forward and reverse motor 503, the arc-shaped blanking plate 501 slowly rotates left and right, and the welding slag on the top of the arc-shaped blanking plate 501 is slowly poured into the solution pool 407 and the filter frame 409 to prevent the welding slag from suddenly falling into the solution pool 407 and causing the oxidant solution in the solution pool 407 to splash. The hydrogen peroxide oxidant solution is poured into the solution pool 407 in advance through the liquid inlet pipe 402, and the welding slag that falls into the filter frame 409 enters the hydrogen peroxide oxidant solution. The hydrogen peroxide can oxidize the welding slag. The metal ions in the slag are oxidized into metal ions dissolved in water. As the welding slag falls, the hydrogen peroxide solution in the solution pool 407 gradually rises, driving the float 412 to rise in the hollow limit tube 411. The float 412 is limited by the hollow limit tube 411 to prevent deviation. The float 412 rises higher and higher and contacts the pressure sensor 414. The pressure sensor 414 transmits the detected pressure value to the PLC controller 11 in the form of an electrical signal. After receiving the pressure signal, the PLC controller 11 controls the liquid pump 403 to start and opens the solenoid valve 408. The solution containing the metal ions is pumped into the liquid outlet pipe 405 through the liquid pumping pipe 404. One end of the liquid outlet pipe 405 is connected to the external sedimentation tank to facilitate the transportation of the solution to the sedimentation tank. In order to facilitate the subsequent extraction of metal ions and prevent excessive overflow of the solution in the solution pool 407, a square hole is opened on the front surface of the solution pool 407, and a sealing strip 410 is arranged on the front surface of the square hole. The sealing plate 401 fits tightly with the sealing strip 410 to increase the sealing performance and prevent leakage of the solution in the solution pool 407. The sealing plate 401 is fixed to the front surface of the solution pool 407 by a hand-tightening bolt. When the solution is pumped out, the hand-tightening bolt is unscrewed, and the sealing plate 401 is pulled by the pull rod on the front surface of the sealing plate 401 to take out the filter frame 409, so as to facilitate the cleaning of impurities in the filter frame 409, thereby achieving the effect of slag connection and slag dissolution. The staff does not need to clean regularly, which reduces the workload and solves the problem of high-frequency welding machine with welding slag self-cleaning function during use.The removed welding slag will fall directly to the ground. In order to prevent the accumulated welding slag from affecting the cleaning of the scraper or wire brush, the staff needs to clean it regularly, which increases the workload, is troublesome, and is prone to injury.
