[0002] A cold welding machine is generally composed of a chassis and a welding gun. During welding, the high heat energy generated by discharge melts the welding material and welds it to the damaged parts of the parts. It is usually used for surfacing and repairing metal parts.

[0003] When welding parts with an existing cold welding machine, the surface of the part is cleaned and placed on the operating table, and then the cold welding machine is started and a welding gun is used to melt the welding wire to cover the part. Finally, the welded part of the part needs to be checked for compliance. During long-term use and observation, it is found that when welding parts with an existing cold welding machine, high heat energy is generated by the discharge of the electrode head of the welding gun for welding. There is a problem that high heat will be generated on the part during welding, resulting in unstable structure of the part itself.

[0004] Therefore, the utility model provides a cold welding machine capable of rapid cooling. Utility Model Content

[0011] Preferably, the second fixing plate and the third fixing plate are both slidably connected with a plurality of second spring rods in the middle; the second spring rods are symmetrically arranged; in this step, by arranging the second spring rods to move to both sides when fixing the parts and generate elastic force so that the ends contact the surface of the parts, parts of different shapes can be clamped and fixed, and the situation of unstable clamping caused by uneven surface shape of the parts can be reduced.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specific examples are given below.

[0024] like Figure 1 to Figure 2As shown, a cold welding machine capable of rapid cooling described in an embodiment of the utility model comprises a welding box 1; a welding table 11 is fixedly connected to the inner side wall of the welding box 1; a water pipe 13 is fixedly connected to the bottom of the welding table 11; the end of the water pipe 13 is connected to a water inlet 12; the end of the water pipe 13 away from the water inlet 12 is connected to a water outlet 14; the ends of the water inlet 12 and the water outlet 14 are located outside the welding box 1; a plurality of ventilation holes 15 are opened on the side wall of the welding box 1; the ventilation holes 15 are symmetrically arranged; a main box 16 is fixedly connected to the top of the welding box 1; a welding gun 17 is connected to the bottom of the main box 16; when working, when welding metal parts, the parts are placed on the surface of the welding table 11 inside the welding box 1, Then start the main box 16 and use the welding gun 17 to weld the parts. When welding is completed, connect the cold water source from the water inlet 12. After the water flows into the water pipe 13, the welding table 11 will be cooled down. The parts in contact with the welding table 11 will also be cooled down at the same time. Finally, the water flows out from the water outlet 14. In this step, the water pipe 13 is set to contact with the welding table 11, so that the welding table 11 can be cooled down when the cold water flows in the water pipe 13. The parts in contact with the welding table 11 will conduct heat. When the temperature of the welding table 11 drops, the temperature on the parts will also drop at the same time, thereby cooling the parts after welding, so as to reduce the situation where the high heat generated during welding causes unqualified welding or the structural instability of the parts themselves, so as to improve the welding effect.

[0025] like Figure 2 As shown, a plurality of heat sinks 2 are fixedly connected to the middle of the water pipe 13; the plurality of heat sinks 2 are in contact with the bottom of the welding platform 11; during operation, when cold water flows in the water pipe 13, the heat sink 2 is connected to the outer wall of the water pipe 13, which can conduct the heat in the water pipe 13 and the heat sink 2 is in contact with the bottom of the welding platform 11, which can conduct the heat to the welding platform 11. In this step, by arranging the heat sink 2 to connect the water pipe 13 and contact with the welding platform 11, the contact area between the water pipe 13 and the welding platform 11 can be increased, so that the temperature of the welding platform 11 can be reduced faster, thereby improving the heat dissipation effect.

[0026] like Figure 1 and Figure 4 As shown, the side wall of the welding box 1 is fixedly connected to a bellows 3; the bellows 3 is arranged to cover the ventilation holes 15 on one side; the inner wall of the bellows 3 is fixedly connected to a fan 31; the side wall of the bellows 3 is provided with a plurality of air holes 32; during operation, when welding is completed, the fan 31 can be started to allow air to pass through the air holes 32 and enter the inside of the welding box 1 from the ventilation holes 15 on the side of the welding box 1, and when the air flow blows onto the parts inside the welding box 1, the parts can be cooled down. In this step, the fan 31 is arranged to blow air inside the welding box 1, so that the parts can be cooled down by blowing air after welding, so that the temperature of the parts can be quickly reduced to improve the heat dissipation effect.

[0027] like Figure 1 As shown, a first fixing plate 4 is fixedly connected to the side wall of the welding box 1; a vacuum pump 41 is fixedly connected to the top of the first fixing plate 4; an air guide pipe 42 is connected to the middle of the vacuum pump 41; an air guide pipe 42 is connected to an air guide cover 43 at the end of the air guide pipe 42; the air guide cover 43 is set to cover the ventilation holes 15 on the side away from the bellows 3; when working, when the fan 31 blows air to the parts, the vacuum pump 41 can be started to exhaust air, and the airflow is extracted from the welding box 1 into the air guide cover 43 and then passes through the air guide pipe 42 into the vacuum pump 41 and then discharged. In this step, the vacuum pump 41 is set to connect the air guide pipe 42 and the air guide cover 43 to exhaust the inside of the welding box 1. When the fan 31 blows air, the flow of air on the surface of the parts inside the welding box 1 can be accelerated, and the temperature on the parts can be taken away faster to improve the heat dissipation effect.

[0028] like Figure 3 As shown, a second fixing plate 5 is fixedly connected to the top of the welding platform 11; a first spring rod 51 is fixedly connected to the side wall of the second fixing plate 5; a pair of slide grooves 53 are opened on the top of the welding platform 11; a third fixing plate 52 is slidably connected to the middle of the slide groove 53; the end of the first spring rod 51 is fixedly connected to the side wall of the third fixing plate 52; during operation, when welding the parts, the third fixing plate 52 is pulled to open the distance between the second fixing plate 5 and the third fixing plate 52, and then the parts are placed between the second fixing plate 5 and the third fixing plate 52, and the third fixing plate 52 is pulled by the elastic force generated by the first spring rod 51 to clamp the parts between the second fixing plate 5 and the third fixing plate 52 to fix the parts. In this step, the first spring rod 51 is set to connect the second fixing plate 5 and the third fixing plate 52, so that the parts can be clamped during welding, and the parts can be fixed to reduce the situation where the position of the parts moves and causes unqualified welding, so as to improve the welding effect.

[0029] like Figure 3 As shown, the middle parts of the second fixing plate 5 and the third fixing plate 52 are both slidably connected with a plurality of second spring rods 6; the second spring rods 6 are symmetrically arranged; during operation, when the part is clamped and fixed by the second fixing plate 5 and the third fixing plate 52, the ends of the second spring rods 6 will contact the surface of the part and move to both sides under the extrusion of the part, which can adapt to parts of different shapes. In this step, by arranging the second spring rods 6 to move to both sides when fixing the part and generate elastic force to make the ends contact the surface of the part, parts of different shapes can be clamped and fixed, and the situation where the uneven surface shape of the part causes unstable clamping can be reduced.

[0030] like Figure 4As shown, the inner wall of the bellows 3 is fixedly connected with filter cotton 7; the filter cotton 7 is arranged near the ventilation hole 15; when working, when the fan 31 blows air into the welding box 1, the airflow will pass through the filter cotton 7 and then enter the welding box 1 from the ventilation hole 15. In this step, by setting the filter cotton 7, the airflow can be filtered when the fan 31 blows air into the welding box 1, so as to reduce the dust contained in the airflow from entering the welding box 1 and falling on the welding part to affect the welding effect.

[0031] Working principle: During operation, when welding metal parts, the parts are placed on the surface of the welding table 11 inside the welding box 1, and then the main box 16 is started and the welding gun 17 is used to weld the parts. When welding is completed, the cold water source is connected from the water inlet 12, and the water flows into the water pipe 13 to cool the welding table 11. The parts in contact with the welding table 11 will also be cooled at the same time. Finally, the water flows out from the water outlet 14. When the cold water flows in the water pipe 13, the heat sink 2 is connected to the outer wall of the water pipe 13, which can conduct the heat in the water pipe 13 and the heat sink 2 is in contact with the bottom of the welding table 11, which can conduct the heat to the welding table 11. When welding is completed, the fan 31 can be started to allow the air flow to enter the welding box 1 from the ventilation hole 15 on the side of the welding box 1 through the air vent 32. When the air flow blows onto the parts inside the welding box 1, the parts can be cooled. When the fan 31 blows air to the parts, the vacuum pump 41 can be started to extract air, and the air flow is drawn out from the welding box 1 into the air guide cover 43, and then enters the vacuum pump 41 through the air guide pipe 42 and is discharged. When welding the parts, the third fixing plate 52 is pulled to increase the distance between the second fixing plate 5 and the third fixing plate 52, and then the parts are placed between the second fixing plate 5 and the third fixing plate 52. The third fixing plate 52 is pulled by the elastic force generated by the first spring rod 51 to clamp the parts between the second fixing plate 5 and the third fixing plate 52 to fix the parts. When the parts are clamped and fixed by the second fixing plate 5 and the third fixing plate 52, the end of the second spring rod 6 will contact the surface of the parts and move to both sides under the extrusion of the parts, which can adapt to parts of different shapes. When the fan 31 blows air into the inside of the welding box 1, the air flow will pass through the filter cotton 7 and then enter the inside of the welding box 1 from the ventilation hole 15.
