Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and particularly relates to a novel electromagnetic welding machine. Background Art

[0002] The magnetic welding machine is a tool for welding waterproof plates and hot-melt gaskets during tunnel internal construction, and is a relatively popular welding product at home and abroad. The magnetic welding machine adopts the principle of electromagnetic induction. Through the non-contact induction principle, the iron sheet arranged in the hot-melt gasket generates heat instantaneously and melts, so that the hot-melt gasket is firmly adhered to the waterproof plate to achieve the welding purpose. The magnetic welding machine is usually of a split structure, including a control chassis and a magnetic welding gun head. The magnetic welding gun head is fixedly connected to the control chassis through a control wire.

[0003] However, during actual use, the control chassis is relatively heavy and is generally placed on the ground or a load-bearing platform. Therefore, the length of the control wire limits the movement range of the magnetic welding gun head, causing inconvenience to the welding work and affecting the work efficiency of the staff. At the same time, when adjusting the working state of the magnetic welding gun head, it needs to be operated on the control chassis, and the operation is relatively cumbersome, which also reduces the work efficiency of the staff to a certain extent. In addition, the structures of the control chassis and the magnetic welding gun head are relatively complex, resulting in a relatively large overall structure of the magnetic welding machine, which is not conducive to product transportation and use.

[0004] Therefore, it is very necessary to improve the existing magnetic welding machine. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides a novel electromagnetic welding machine, which has the effects of convenient operation, flexible work, compact structure, smaller volume, and being convenient for transportation and use.

The heat dissipation component includes an electronic radiator, a first cooling fan, and a second cooling fan. The control component includes a first control circuit board and a second control circuit board fixedly connected to both sides of the electronic radiator. The magnetic welding gun head includes a coil component and a magnetic welding cover plate adapted to the coil cover plate.

[0007] By adopting the above technical solution, the originally independently existing control chassis is miniaturized into a control mechanism and the control mechanism is integrated into the magnetic welding gun body to form an integrated product, making the structure more compact, the overall volume of the equipment smaller, and convenient for transportation and user use.

[0008] The present utility model is further configured as follows: A gun body head adapted to the magnetic welding gun head is provided at the front end of the magnetic welding gun body. A gun head mounting notch is formed on the gun body head, and the coil cover plate is externally sleeved outside the gun head mounting notch.

A fixing through hole adapted to the coil support column is formed in the middle of the coil fixing plate. A support step abutting against the coil support column is formed on the fixing through hole. A support through hole communicating with the fixing through hole is further formed on the support column.

[0009] By adopting the above technical solution, after the high-frequency coil in the coil assembly is energized, the iron sheet arranged in the hot melt gasket generates heat and melts, so as to weld and fix the welding part. The first coil through holes, the second coil through holes and the support through holes can all play a role in ventilation and heat dissipation.

[0010] The present utility model is further configured as follows: A number of uniformly distributed first cover plate through holes and second cover plate through holes communicating with the support through hole are formed on the magnetic welding cover plate.

A first air outlet hole and a second air outlet hole adapted to the first cover plate through hole and the second cover plate through hole are formed on the silica gel sleeve.

[0011] By adopting the above technical solution, a number of through holes on the magnetic welding gun head play an effect of ventilation and heat dissipation on the coil assembly.

The coil assembly 21 includes a disc-shaped coil fixing plate 211 and a coil support column 212 passing through the center of the coil fixing plate 211. A high-frequency coil 213 adapted to it is sleeved on the coil support column 212. One end of the outer side of the coil support column 212 is in abutting connection with the inner side of the magnetic welding cover plate 22. Both the coil fixing plate 211 and the coil support column 212 are made of non-magnetic materials. After the high-frequency coil 213 in the coil assembly 21 is energized, the iron sheet arranged in the heat-melting gasket generates heat and melts, so as to weld and fix the welding part.

[0039] On both the left and right sides of the magnetic welding cover plate 22, there are cover plate limiting parts 221. The cover plate limiting parts 221 are fixedly connected to the gun body head by setting cover plate screws.

The second cooling fan 33 is engaged in the gun head mounting notch 11 inside through the set limit block 112 and cooperates with the magnetic welding gun head 2. The first cooling fan 32 dissipates heat from the electronic radiator 31 and the magnetic welding gun head 2 behind it by blowing air towards the electronic radiator 31. The second cooling fan 33 dissipates heat from the magnetic welding gun head 2 by blowing air towards the magnetic welding gun head 2. The control component 4 includes a first control circuit board 41 and a second control circuit board 42 fixedly connected to both sides of the electronic radiator 31. The control component 4 also has a time relay 43 with a control panel 44. The control panel 44 is provided with a display screen 441 and a number of control buttons 442 adapted to the display screen 441. The display screen 441 and the control buttons 442 are respectively used to display and adjust the welding duration. The time relay 43 is inserted into the magnetic welding gun body 1 and its control panel 44 is exposed outside the magnetic welding gun body 1. The time relay 43 is used to control the welding duration.

[0042] The control component 4 also includes a power switch 45, a working switch 46 and a number of working indicator lights 47. The power switch 45 is fixedly connected to one side of the magnetic welding gun body 1. The power switch 45 is used to control the power-on state of the magnetic welding machine body so as to control whether the magnetic welding machine body can work. A power fuse 48 adapted to it is also arranged below the power switch 45. The power fuse 48 can automatically cut off the circuit in case of a circuit failure, avoid equipment damage and prevent the spread of accidents. The working switch 46 is arranged at the lower part of the magnetic welding gun body 1. A holding handle 12 fixedly connected to it is arranged at the lower part of the magnetic welding gun body 1. The holding handle 12 is fixedly connected to the working switch 46. The working switch 46 controls whether the magnetic welding gun head 2 performs welding work. A power through hole 121 is opened at the lower end of the holding handle 12. A power cord electrically connected to the control component 4 is inserted into the power through hole 121. The power cord delivers 220V of mains electricity to the control mechanism for the equipment body to perform welding work. The working indicator lights 47 are located on the surface of the magnetic welding gun body 1. The working indicator lights 47 prompt the staff about the current working state of the magnetic welding machine body.

[0043] An air inlet part and an air outlet part adapted to the first cooling fan 32 and the second cooling fan 33 are also arranged on the front and rear sides of the magnetic welding gun body 1. Air inlet through holes 13 and air outlet through holes 14 are evenly opened on the air inlet part and the air outlet part respectively. When the first cooling fan 32 and the second cooling fan 33 perform heat dissipation work, the external air of the magnetic welding gun body 1 flows in from the air inlet through holes 13 and blows out from the air outlet through holes 14.

[0044] The magnetic welding torch body 1 is provided with a split structure. The magnetic welding torch body 1 includes a first magnetic welding housing 15 and a second magnetic welding housing 16 which are adapted to each other. The first magnetic welding housing 15 and the second magnetic welding housing 16 are fixedly connected to each other by bolts. The split structure of the magnetic welding torch body 1 facilitates the installation and fixation of the control mechanism.

[0045] Its working process is as follows: First, connect the 220V mains power through the power cord to make the magnetic welding machine body energized. Then, adjust the welding duration of the magnetic welding machine body through the control button 442 on the control panel 44 (the welding duration is adjusted according to the actual welding effect). Subsequently, turn on the power switch 45. The working indicator light 47 will light up and flash after a 3S delay when the power switch 45 is turned on. The first cooling fan 32 and the second cooling fan 33 start to work and continuously ventilate and dissipate heat from the control mechanism inside the magnetic welding torch body 1 and the magnetic welding gun head 2. Then, the magnetic welding gun head 2 can be aligned with the welding part for welding work. When welding, the high-frequency coil 213 in the coil assembly 21 is energized, causing the iron sheet arranged in the heat-melting gasket to heat up and melt, thereby welding and fixing the welding part. And the operator needs to press the working switch 46 with hand to ensure the continuous operation of the magnetic welding machine body. If released, the welding work will stop. At the same time, the welding work will also stop when the welding duration reaches.

[0046] Embodiment 2. On the basis of Embodiment 1, as Figure 7 and 8 shown, an auxiliary handle 5 adapted to it is arranged on one side of the magnetic welding torch body 1. A handle protrusion 51 integrated with it is arranged on the auxiliary handle 5. Handle mounting holes 17 adapted to the handle protrusion 51 are respectively opened on the left and right sides of the magnetic welding torch body 1. The handle protrusion 51 penetrates through the handle mounting hole 17 and is detachably connected to one side of the electronic radiator 31 by a threaded manner. Handle screw holes 311 adapted to the handle protrusion 51 are respectively opened on the left and right sides of the electronic radiator 31. By arranging the auxiliary handle 5, it is convenient for the operator to hold the magnetic welding machine body with both hands and press the magnetic welding gun head 2 against the welding part with both hands, which is convenient for applying force and has a better welding effect, being firm and reliable.

[0047] Its working process is as follows: Before the magnetic welding machine body starts welding work, screw the auxiliary handle 5 to one side of the magnetic welding machine body. The subsequent welding work is as described in the working process of Embodiment 1.
