Description

Technical Field

[0001] This utility model relates to the field of bending technology, specifically to a water-cooled cooling device for bending photovoltaic metal parts. Background Technology

[0002] Photovoltaic metal fittings are key metal components in photovoltaic power generation systems used to support, fix, connect, and protect photovoltaic modules and other equipment. Their performance and reliability directly affect the system's safety and power generation efficiency. The following are the classifications, materials, and common products of photovoltaic metal fittings. During manufacturing, they require bending to meet usage requirements.

[0003] During repeated stamping processes, the stamping blocks of a bending machine are prone to high temperatures. High temperatures cause the stamping blocks on the bending machine to wear out faster, requiring more frequent maintenance and replacement, increasing production costs. In addition, high temperatures may make the operating environment hotter, increasing the risk of heat injury to operators.

[0004] Therefore, it is necessary to invent a water-cooled cooling device for bending photovoltaic metal parts to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a water-cooled cooling device for bending photovoltaic metal parts. By cooperating with the bending bracket and the bending cooling mechanism, the device cools the stamping block, thereby solving the problems in the prior art where high temperatures cause the stamping block on the bending machine to wear faster, requiring more frequent maintenance and replacement, increasing production costs, and high temperatures may also make the operating environment hotter, increasing the risk of heat injury to the operator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled cooling device for bending photovoltaic metal accessories, comprising a bending bracket, a bending cooling mechanism disposed inside the bending bracket, a connecting plate disposed inside the bending bracket, a thickened stamping head fixedly connected to the bottom end of the connecting plate, a through groove formed on the surface of the thickened stamping head, an inlay groove communicating with the through groove formed on the surface of the thickened stamping head, and a heat exchange block inlaid inside the inlay groove, the heat exchange block being made of porous copper alloy material, several sets of reinforcing ribs fixedly connected to the surface of the heat exchange block, the reinforcing ribs being fixedly connected to the inner side wall of the thickened stamping head, a water outlet hole formed on the outer side wall of the thickened stamping head, and two sets of baffle plates fixedly connected to the bottom end of the connecting plate, so that high-pressure water mist enters the interior of the through groove and cooperates with the heat exchange block to cool the thickened stamping head, and the baffle plates reflect the high-pressure water mist to ensure that the water mist enters the through groove and exchanges heat with the heat exchange block.

[0007] Preferably, drainage holes are provided on both sides of the bottom of the bending bracket, a bending groove is provided at the bottom of the bending bracket, and a bending cylinder is fixedly connected to the top of the bending bracket. The output end of the bending cylinder is fixedly connected to the connecting plate, and the bending cylinder is activated to drive the connecting plate to rise and fall.

[0008] Preferably, a water tank is fixedly connected to the back side of the bending bracket, and a water inlet pipe is fixedly connected to the top of the water tank to introduce cooling water into the water tank.

[0009] Preferably, both ends of the water tank are fixedly connected to water outlet pipes, and the water outlet end of the water outlet pipe is fixedly connected to an installation block. The installation block is fixedly connected to both sides of the bending bracket, and the water outlet pipe is fixed by the installation block.

[0010] Preferably, the inner wall of the bending bracket is provided with a sliding groove, and the two ends of the thickened stamping head are slidably connected to the inside of the sliding groove, so as to realize the sliding of the thickened stamping head by means of the sliding groove.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

The water mist is precisely refracted into the passage groove through the baffle plate, achieving full contact between the water mist and the heat exchange block. This allows the high-pressure water mist to form a liquid film on the surface of the heat exchange block, and a large number of bubble nuclei to form on the surface of the liquid film. The growth and detachment process carries away a large amount of latent heat. Attached Figure Description

[0023] This utility model provides, for example Figure 1-5The device shown is a water-cooled cooling device for bending photovoltaic metal fittings. It includes a bending bracket 1, with a bending cooling mechanism 2 inside the bracket 1. The bending cooling mechanism 2 includes a connecting plate 201 inside the bracket 1. A thickened stamping head 202 is fixedly connected to the bottom end of the connecting plate 201. A through groove 203 is formed on the surface of the thickened stamping head 202, and an inlay groove communicating with the through groove 203 is formed on the surface of the thickened stamping head 202. A heat exchange block 204 is inlaid inside the inlay groove. The heat exchange block 204 is made of porous copper alloy material, and several sets of reinforcing ribs 205 are fixedly connected to the surface of the heat exchange block 204. The reinforcing ribs 205 are fixedly connected to... The inner wall of the thickened stamping head 202 is provided with a water outlet 206. Two sets of baffle plates 207 are fixedly connected to the bottom end of the connecting plate 201, so that the high-pressure water mist enters the interior of the through groove 203 and cooperates with the heat exchange block 204 to cool the thickened stamping head 202. The baffle plates 207 reflect the high-pressure water mist, ensuring that the water mist enters the through groove 203 and exchanges heat with the heat exchange block 204. Drainage holes are provided on both sides of the bottom of the bending bracket 1. A bending groove 3 is provided at the bottom of the bending bracket 1. A bending cylinder 4 is fixedly connected to the top of the bending bracket 1. The output end of the bending cylinder 4 is fixedly connected to the connecting plate 201 to start the bending process. Cylinder 4 drives the connecting plate 201 to rise and fall. A water tank 8 is fixedly connected to the back side of the bending bracket 1. A water inlet pipe 6 is fixedly connected to the top of the water tank 8, through which cooling water is introduced into the water tank 8. Water outlet pipes 11 are fixedly connected to both ends of the water tank 8. Mounting blocks 5 are fixedly connected to the outlet ends of the water outlet pipes 11. The mounting blocks 5 are fixedly connected to both sides of the bending bracket 1, and the water outlet pipes 11 are fixed by the mounting blocks 5. A sliding groove 10 is opened on the inner side wall of the bending bracket 1. The two ends of the thickened stamping head 202 are slidably connected to the inside of the sliding groove 10, and the sliding groove 10 is used to realize the sliding of the thickened stamping head 202. The mounting blocks 5 are located inside the sliding groove 10. A crash pad 7 is fixedly connected to the bottom of the moving groove 10 and is located above the thickened stamping head 202. A high-pressure sprayer 9 is fixedly connected to the inner wall of the mounting block 5. The high-pressure sprayer 9 is located outside the baffle plate 207. High-pressure water mist is sprayed through the high-pressure sprayer 9. Through the cooperation of the bending bracket 1 and the bending cooling mechanism 2, the high-pressure sprayer 9 sprays high-pressure water mist onto the baffle plate 207. The water mist is accurately refracted into the interior of the passage groove 203 through the baffle plate 207, so that the water mist can fully contact the heat exchange block 204. The high-pressure water mist forms a liquid film on the surface of the heat exchange block 204, and a large number of bubble nuclei are formed on the surface of the liquid film. The growth and detachment process carries away a large amount of latent heat.

[0024] The working principle of this practical application is as follows:

[0025] Refer to the instruction manual appendix Figure 1-5When it is necessary to bend photovoltaic metal parts, the workpiece is placed on the surface of the bending groove 3, and then the bending cylinder 4 is started to drive the connecting plate 201 to rise and fall, thereby driving the thickened stamping head 202 to rise and fall inside the sliding groove 10 to complete the bending work. When the thickened stamping head 202 moves upward, the high-pressure sprayer 9 is started, and the water mist hits the baffle plate 207. According to the height of the thickened stamping head 202, the water mist is refracted to different distances when it hits the baffle plate 207, so that the droplets of high-pressure water mist are distributed inside the through groove 203, so that it forms a liquid film with the heat exchange block 204, and a large number of bubble nuclei are formed on the surface of the liquid film and grow. The process of detachment carries away a large amount of latent heat, and the unevaporated water is discharged through the water outlet 206 to avoid excessive water accumulation.
