Description

Technical Field

[0001] The utility model belongs to the field of argon arc welding machines and relates to an argon arc welding machine, in particular to an argon arc welding machine with a heat dissipation structure. Background Art

[0002] Argon arc welding machine is a machine that uses argon arc welding to perform welding operations. It adopts high-voltage breakdown arc starting method. Argon arc welding, also known as tungsten inert gas shielded arc welding, refers to a welding method that uses industrial tungsten or active tungsten as a non-melting electrode and argon gas as protection, referred to as TIG.

[0003] The argon arc welding machine generates a lot of heat during use, and the argon arc welding machine itself has poor heat dissipation effect. In order to prevent the high temperature from damaging the motherboard and other electronic components inside the argon arc welding machine, the argon arc welding machine needs to be shut down and placed, and the motherboard needs to be cooled naturally before it can continue to work, which affects work efficiency. The current argon arc welding machine usually uses heat dissipation holes for air cooling, which has poor heat dissipation effect and easily causes external impurities to enter the welding machine. Due to the high metal dust in the welding environment, it is easy to cause a short circuit on the motherboard, causing damage to the welding machine.

[0004] For example, an argon arc welding machine with application number 202320443252.6 includes an argon arc welding body, a terminal block is provided at the bottom of the front of the argon arc welding body, an annular groove is provided on the side of the terminal block, a protective cover is embedded in the annular groove, a tooth groove is provided at the bottom of the protective cover, a cavity is provided at the bottom of the welding body, and a rotating shaft is connected to the inner wall of the cavity on both sides.

[0005] The above patent protects the connection between the terminal block and the connecting wire by providing a protective cover outside the terminal block and driving the protective cover to move through a rotating shaft. However, in terms of heat dissipation, the welding body is only provided with a heat dissipation window and a dustproof strip. The temperature inside the welding body is easy to rise, affecting the working efficiency of the welding machine and having poor heat dissipation efficiency. Utility Model Content

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] The cooling fan 5 is used to extract air from the welding machine, so that the external airflow enters the welding machine body 1 through the heat dissipation box 2; the heat dissipation box 2 is used to cool the airflow through the cooling channel 24 and the condenser 4, and filter the impurities in the airflow through the dustproof net 3; the pull rod 12 and the roller 13 cooperate to facilitate the movement of the welding machine body 1.

[0026] As shown in the figure, the recessed portion 11 is provided with a mounting groove 112, with a screw hole 112a defined therein. The heat sink 2 is provided with a corresponding mounting portion 25, with a through-hole 251 defined therein. A screw is installed between the screw hole 112a and the through-hole 251. The mounting groove 112 accommodates the mounting portion 25, facilitating the positioning and installation of the heat sink 2. The screw passes through the through-hole 251 of the mounting portion 25 and the screw hole 112a of the mounting groove 112, securing the heat sink 2 to the welding machine body 1. The mounting groove 112, the recessed portion 11, and the heat sink 2 cooperate to form a tortuous contact surface, enhancing sealing.

[0027] As shown in the figure, a sealing gasket 6 is attached to the mounting groove 112. The sealing gasket 6 is used to fill the gap between the mounting groove 112 and the mounting portion 25 to enhance the sealing performance.

[0028] As shown in the figure, the dustproof net 3 is provided with a slider 31, and the heat dissipation box 2 is provided with a corresponding slide rail 26. The slide rail 26 and the slider 31 cooperate to enable the dustproof net 3 to slide in the heat dissipation box 2, which is convenient for positioning and installation of the dustproof net 3.

[0029] As shown in the figure, the dust screen 3 is provided with a fixing portion 32, which defines a slot 321. The fixing slot 21 defines a corresponding groove 211, and a clamping block 7 is installed next to the groove 211. The fixing portion 32 engages with the clamping block 7 through the slot 321 and is fixed in the groove 211, thereby securing the dust screen 3 in the fixing slot 21.

[0030] As shown in the figure, a return spring 8 is provided between the block 7 and the dust screen 3, and a protrusion 71 is provided on the block 7. The return spring 8 allows the block 7 to move back and forth, facilitating the reset of the block 7 after the dust screen 3 is inserted into the fixing slot 21, so that the block 7 is locked into the fixing slot 321. The protrusion 71 is used to push the block 7 out of the fixing slot 321, facilitating the removal of the dust screen 3 from the fixing slot 21.

[0031] As shown in the figure, the block 7 is provided with a first bevel portion 72, and the fixing portion 32 is provided with a second bevel portion 322. The first bevel portion 72 and the second bevel portion 322 cooperate so that when the dust screen 3 is inserted into the fixing slot 21, the fixing portion 32 pushes the block 7 to shift, facilitating the insertion of the dust screen 3 into the fixing slot 21 and improving the efficiency of replacing the dust screen 3.

[0032] As shown in the figure, the condenser 4 is U-shaped. The condenser 4, the water outlet 22, and the water inlet 23 are connected by a rubber hose 9. The cooling channel 24 has a larger diameter than the condenser 4. The U-shaped condenser 4 facilitates removal and replacement of the condenser 4 during assembly and disassembly. The portion exposed outside the heat sink 2 facilitates observation of the condenser 4's operating condition. The rubber hose 9 is used to connect the condenser 4 to the condenser 4. The cooling channel 24 between the condenser 4 and the water inlet 23 and outlet 22 has a larger diameter than the condenser 4, facilitating airflow through the condenser 4 and, after being fully cooled by the condenser 4, entering the welding machine body.

[0033] The working principle of the present invention is as follows: after the welding machine body 1 is connected, a water pipe is connected to the heat dissipation box 2, and the cooling water in the water pipe flows into the condenser tube 4. Then, the heat dissipation fan 5 is started, and the heat dissipation fan 5 extracts the air in the welding machine body 1. The outside air flows into the welding machine body 1 from the heat dissipation strip holes 111. The airflow passes through the dustproof net 3 of the heat dissipation box 2 and enters the cooling channel 24. After passing through the gap between the cooling channel 24 and the condenser tube 4, the airflow is fully cooled by the cold air generated by the condenser tube 4, and then leaves the cooling channel 24 through the opening 241 and enters the welding machine body through another dustproof net 3. The welding machine body 1 can be moved by the pull rod 12 and the pulley.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
