[0001] This invention belongs to the technical field of fence welding equipment, and specifically relates to a fence welding auxiliary device. Background Technology

This type of fencing is typically made of low-carbon galvanized steel wire welded together, and the surface is coated with PE and subjected to high-temperature plasticizing treatment.

The through-mounted pipe connects to multiple sets of horizontal pipes, and horizontal telescopic pipes connect between adjacent horizontal pipes; vertical telescopic pipes connect to the upper and lower sides of the horizontal pipes.

Beneficial effects of this invention:

[0010] 1. This invention features a fence cooling adjustment structure that eliminates the need for electronic detection components such as temperature sensors. Multiple external observation windows allow for direct reading of the indicated solution level in different areas. A longer indicated solution level indicates a higher temperature after welding, providing visualization and intuitive readings of the temperature in each area. 2. Combined with a controlled cooling structure, low-temperature cooling water is produced by activating an auxiliary fan and simultaneously energizing the cooling element. The operator, referring to the indicated solution level seen through the external observation windows, controls an electric actuator to drive a piston that compresses the low-temperature water. Higher temperatures correspond to longer indicated solution levels, requiring more cooling water to be injected. The horizontal and vertical telescopic tubes extend under water pressure, increasing the heat-absorbing contact area of ​​the thermally conductive silicone components and improving heat dissipation. At lower temperatures, less cooling water is injected, and the telescopic tubes do not extend, relying on the horizontal tube for indirect heat absorption. This non-contact cooling method avoids fence cracking caused by direct water cooling, balancing heat dissipation and workpiece protection. Attached Figure Description

[0016] As shown in Figures 1 and 2, this invention discloses a fence welding auxiliary device.

A connecting observation window 18 is provided on the outer wall of the schematic fixed plate 10, connecting to the solid temporary storage tank 12; an external observation window 19 is provided in the middle fixed frame 37, and the external observation window 19 and the connecting observation window 18 are interconnected.

[0018] Referring to Figures 1, 3, 6, and 7, in the refrigeration control structure 2, the water storage tank 25 is fixed to the top of the welding clamping assembly 3; the refrigerated water container 30 is fixed to the outer wall of the welding clamping assembly 3; a copper temperature guide frame 24 is fixed on the refrigerated water container 30, a refrigeration bracket 21 is fixed above the copper temperature guide frame 24, and refrigeration plates 20 are fixed between the refrigeration brackets 21; a fan bracket 23 is fixed to the top of the refrigeration bracket 21, and an auxiliary fan 22 is mounted on the fan bracket 23; the heating surface of the refrigeration plate 20 faces the auxiliary fan 22, and the cooling surface faces the copper temperature guide frame 24. The electric push rod 28 is fixed to the outer wall of the welding clamping assembly 3, and the piston 29 is slidably assembled inside the refrigerated water container 30, with the piston 29 connected to the output end of the electric push rod 28. A through-mounted pipe 31 is connected to the side wall of the refrigerated water container 30, penetrating the side wall of the welding clamping assembly 3, and connecting multiple sets of horizontal pipes 32; horizontal telescopic pipes 34 connect adjacent horizontal pipes 32; and vertical telescopic pipes 33 connect the upper and lower sides of the horizontal pipes 32. A main delivery pipe 26 is led out from the water storage tank 25, the main delivery pipe 26 is connected to a branch pipe 27, and the branch pipe 27 is connected to the cooling water container 30.

[0019] As shown in Figures 1 and 2, the welding clamping assembly 3 consists of: a central fixed frame 37 fixed to a U-shaped bracket 4, and the central fixed frame 37 and the water storage tank 25 fixed to each other; the body of the clamping electric push cylinder 38 is fixed to the U-shaped bracket 4; a horizontal guide bracket 41 is fixed on the central fixed frame 37, and a horizontal sliding frame 39 is slidably fitted into the horizontal guide bracket 41, with the horizontal sliding frame 39 connected to the output end of the clamping electric push cylinder 38; a fence support plate 40 is provided on the horizontal sliding frame 39; upper and lower limit brackets 42 are fixed at the upper and lower positions of the central fixed frame 37, and the upper and lower limit brackets 42 complete the auxiliary positioning of the fence; the body of the electric push rod 28 is arranged inside the horizontal sliding frame 39.

[0020] The flexible storage shell 17, solid temporary storage tank 12, solidification support platform 16, and bottom sliding platform 13 are coated with a hydrophobic and oleophobic coating 35. The wax block 6 has a parallelogram cross-section and is made of paraffin wax. The wax block 6 can slide on the bottom sliding platform 13 and solidification support platform 16 and can move between the solid temporary storage tank 12 and the flexible storage shell 17. The schematic solution 7 is a mixture of high-temperature resistant pigment and water. The flexible storage shell 17, horizontal pipe 32, vertical telescopic pipe 33, and horizontal telescopic pipe 34 are all made of thermally conductive silicone. A one-way valve 36 is installed at the connection point between the branch pipe 27 and the cooling water container 30. The one-way valve 36 ensures that water can only flow into the cooling water container 30 from the branch pipe 27.

[0021] The actual working process of this device is as follows: The wax block 6 remains solid at room temperature. After the fence welding operation is completed, the temperature around the multiple sets of schematic fixing plates 10 rises, and the melting rate of the wax block 6 varies at different locations. The solid temporary storage tank 12 is arranged at an angle, and the melted wax flows through the wax flow hole 15 into the flexible storage shell 17 for storage. The flexible storage shell 17 is made of thermally conductive silicone, which can transfer ambient heat, but the shell itself will not melt. The surfaces of the flexible storage shell 17, the solid temporary storage tank 12, the solidification support platform 16, and the bottom sliding platform 13 are coated with a hydrophobic and oleophobic coating 35 to prevent wax from adhering. The heat comes from the fence side, and the end of the wax block 6 closest to the flexible storage shell 17 melts first; the unmelted solid wax block 6 slides along the bottom sliding platform 13 towards the flexible storage shell 17; only the liquefied wax can pass through the wax flow hole 15, and the solid wax block 6 is intercepted by the sealing plate 14. After the wax block 6 gradually melts, the solution flow channel 11 is no longer blocked, and the indicated solution 7 flows from the solution container 8 through the solution flow channel 11 into the solid storage tank 12. The higher the ambient temperature, the faster the wax block 6 melts, the faster the indicated solution 7 flows into the solid storage tank 12, and the higher the indicated solution 7 level inside the solid storage tank 12. The operator can observe the height of the colored indicated solution 7 through the external observation window 19; the longer the liquid level, the higher the temperature at that point, achieving intuitive temperature indication without the need for electronic temperature measuring devices.

[0022] The auxiliary fan 22 is turned on to power the cooling chip 20. The auxiliary fan 22 removes heat from the heating surface of the cooling chip 20, and the cooling energy from the cooling surface is transferred to the cooling water container 30 through the copper temperature guide frame 24, thereby cooling the water inside the water storage tank 25 to form low-temperature cooling water. The low-temperature cooling water in the water storage tank 25 enters the branch pipe 27 along the main delivery pipe 26 and is sent to each cooling water container 30. Based on the liquid level of the indicated solution 7 seen through the external observation window 19, the operator controls the electric push rod 28 to drive the piston 29 to squeeze the low-temperature water inside the cooling water container 30. When the liquid level of the indicated solution 7 is high (high temperature), the piston 29 pressurizes more low-temperature water into the through-installation pipe 31, flowing into the horizontal pipe 32, the horizontal telescopic pipe 34, and the vertical telescopic pipe 33; the water pressure increases, the horizontal telescopic pipe 34 and the vertical telescopic pipe 33 extend outward, the heat-absorbing contact area of ​​the thermally conductive silicone component increases, and the heat dissipation capacity is improved. The solution 7 is at a low level (low temperature), resulting in a small amount of cooling water being injected. The horizontal telescopic pipe 34 and the vertical telescopic pipe 33 remain in a contracted state, relying on the horizontal pipe 32 for indirect heat absorption. The entire cooling system does not directly contact the fence workpiece, thus achieving cooling while avoiding rapid cooling that could cause cracking or damage to the fence.
