[0002] High-frequency welding machines can not only be used for welding various metal materials, but also for processes such as heat penetration, smelting, and heat treatment. It forms a high-frequency magnetic field by passing a high-frequency current through the inductor coil, so that an induced current proportional to the magnetic field strength is generated inside the metal object in the magnetic field, thereby using the principle of current thermal effect to generate heat and quickly heat the metal object.

The operation status of the welding machine is displayed through the display panel 104. The lighting lamp 105 is used to provide lighting for a specific area of ​​the welding machine. The electromagnetic heating element 109 connected to the internal circuit of the body 101 is installed through the first combination frame 106, the second combination frame 107, and the bracket 108. Through the operation of the electromagnetic heating element 109, a high-frequency magnetic field is formed in a part of the travel path of some parts of the feeding assembly 3. The heat insulation board 110 is used to prevent the high temperature generated when the workpiece passes through the high-frequency magnetic field from affecting the body 101.

[0028] In this embodiment: the cooling component 2 includes an air cooler 201 fixedly installed in the body 101, the air outlet end of the air cooler 201 is fixedly connected to a connecting pipe 202, the upper end of the connecting pipe 202 is fixedly connected to a joint 203, a positioning ring 204 is fixedly connected to the body 101, and an air outlet pipe 205 is arranged between the joint 203 and the positioning ring 204; the cold air generated by the air cooler 201 is introduced into the joint 203 through the connecting pipe 202, and the cold air entering the joint 203 will enter the air outlet pipe 205 fixed by the positioning ring 204 under the action of air pressure, and blow toward the feeding component 3 along the air outlet pipe 205.

[0029] In this embodiment: the feeding assembly 3 includes a loading part for placing the workpieces to be welded after splicing, a conveying part that can limit the movable range of the loading part, and a driving part that can drive the loading part to move continuously in the welding machine. The conveying part includes a shaft seat 301 fixedly installed in the welding assembly 1, and a rotating shaft 302 is movably connected between the shaft seats 301 with the same lateral position. A transmission wheel 303 is fixedly connected to the outer side of the rotating shaft 302, and a conveyor belt 304 is arranged between the transmission wheels 303. The loading part includes a carrier plate 305 fixedly connected to the outer side of the conveyor belt 304, a placing cylinder 306 is fixedly connected to the carrier plate 305, and a heat insulation sheet 307 is fixedly connected to the placing cylinder 306. The driving part includes a motor 308 fixedly installed in the welding assembly 1, and a first pulley 309 is fixedly connected to the output end of the motor 308, and a second pulley 310 is fixedly connected to the front end of one of the rotating shafts 302, and a belt 311 is arranged between the first pulley 309 and the second pulley 310.

At the same time, the transmission wheel 303 can limit the movable range of the conveyor belt 304 to prevent the conveyor belt 304 from deviating when rotating. The carrier plate 305 connected to the placement cylinder 306 is installed through the conveyor belt 304, and After its own rotation, it drives it to move inside the welding machine, and the workpiece to be welded is placed in the placement cylinder 306. The heat insulation sheet 307 can prevent the high temperature generated when the workpiece passes through the electromagnetic heating element 109 from being quickly transferred to the carrier plate 305 and the placement cylinder 306. The rotation of the output end of the motor 308 is transmitted to the rotating shaft 302 connected to the second pulley 310 through the first pulley 309, the belt 311, and the second pulley 310, and the workpiece falling above it is guided out of the welding machine through the guide rack 312.

[0030] Working principle: When the high-frequency welding machine is installed and used, the current and frequency of the electromagnetic heating element 109 are controlled through the control panel 103 according to the welding needs of the workpiece to be welded, so that a high-frequency magnetic field of the required strength is formed in the electromagnetic heating element 109; then the cooling fan 201 is operated through the control panel 103, so that the air outlet 205 can continuously blow out cold air, and the motor 308 is operated through the control panel 103 to drive the conveyor belt 304 to rotate counterclockwise. After completion, the staff can place the workpieces that have been spliced ​​and filled with a proper amount of flux at the weld in the placement cylinder 306 one by one on the side of the machine body 101 away from the cooling component 2, and continue to rotate counterclockwise. Driven by the clockwise rotating conveyor belt 304, the workpiece will pass through the bottom of the second assembly frame 107, between the electromagnetic heating elements 109, under the first assembly frame 106, and between the air outlet duct 205 in sequence. When passing through the electromagnetic heating element 109 and the air outlet duct 205, the workpiece will experience a process of rapid heating and cooling in sequence under the action of the high-frequency magnetic field and cold air. During the heating process, the weld of the workpiece will gradually fuse and bond. When the workpiece that has been cooled continues to move to the top of the guide frame 312 with the conveyor belt 304, the posture of the workpiece will continue to change with the rotation of the conveyor belt 304 until it falls on the guide frame 312 and leaves the welding machine along the guide frame 312.
