Description

Technical Field

[0001] This utility model relates to the field of cold pressing technology for heat dissipation plates, specifically a cold pressing forming device for heat dissipation plates of explosion-proof boxes used in mining. Background Technology

[0002] Mining explosion-proof enclosures are electrical devices specifically designed for flammable and explosive environments such as mines. Their main function is to provide a safe and reliable power supply and prevent explosions caused by electrical equipment malfunctions. Because the enclosure generates heat during use, it is sometimes equipped with an air-cooled heat dissipation structure. To improve heat dissipation efficiency, during the manufacturing process, the heat dissipation plates are sometimes cold-pressed using a cold-pressing device. This process presses several U-shaped grooves into the heat dissipation plates, increasing the contact area between the plates and the air, thus improving heat dissipation. However, existing cold-pressing devices for mining explosion-proof enclosure heat dissipation plates can be problematic. During cold pressing, some heat dissipation plates may have surface contamination from storage. This contamination can be pressed onto the plates, affecting their quality. Furthermore, the heat generated during cold pressing poses a risk of burns to workers during unloading or transport. Utility Model Content

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-4 In this embodiment of the utility model, the cold pressing forming device for the heat dissipation plate of the explosion-proof box in the mine includes a pressing module 100 and a cleaning module 200.

[0036] The pressing module 100 can cold press the heat sink. The cleaning module 200 is mounted on the pressing module 100. The cleaning module 200 includes a cleaning box 210, with openings on both sides. Two rotating rods 211 are rotatably connected to the inner side of the cleaning box 210, and two cleaning rods 220 are rotatably connected to the inner side of the cleaning box 210. The cleaning rods 220 are located between the two rotating rods 211, and cleaning cotton is fixedly connected to the sides of the cleaning rods 220. The inner side of the cleaning box 210 is fixedly connected to... There is a guide plate 212. A filter frame 213 is fixedly connected to the bottom of the inner side of the cleaning box 210. The filter frame 213 is located at the bottom of the inner side of the cleaning box 210. U-shaped tube 1 240 and U-shaped tube 250 are fixedly connected to the inner side of the cleaning box 210. U-shaped tube 1 240 and U-shaped tube 250 are located on both sides of the cleaning rod 220, and both U-shaped tube 1 240 and U-shaped tube 250 are located between two rotating rods 211. Several nozzles are provided on the sides of U-shaped tube 1 240 and U-shaped tube 250.

[0037] Specifically, the unpressed heat sink can enter the cleaning box 210 through an opening slot, then pass sequentially through a rotating rod 211, the inside of U-shaped tube 240, between two cleaning rods 220, the top of the guide plate 212, the inside of U-shaped tube 250, and another rotating rod 211, before exiting the cleaning box 210 through another opening slot. After the heat sink passes the top of the rotating rod 211 and then between the two cleaning rods 220, it can be guided by the guide plate 212 to move smoothly to the cleaning box 210. On another rotating rod 211, water can be sprayed onto the heat sink through the nozzle on the U-shaped tube 240, and then the heat sink can be cleaned and wiped through the cleaning cotton on the cleaning rod 220. After cleaning with the cleaning cotton, air is blown onto the heat sink through the nozzle on the U-shaped tube 250 to dry the surface of the heat sink. In this way, before the heat sink is pressed by the pressing module 100, the surface of the heat sink can be cleaned inside the cleaning box 210, which helps to improve the cleanliness of the heat sink surface and helps to ensure the quality of the heat sink.

[0038] The height of the cleaning rod 220 at the bottom can be lower than the height of the rotating rod 211. This allows the heat sink to bend downwards at a certain angle when it passes between the top of the two rotating rods 211 and the two cleaning rods 220. The water sprayed from the U-shaped tube 240 can be concentrated as much as possible in the bent part of the heat sink, minimizing the flow of water out of the cleaning box 210. In addition, the nozzle on the U-shaped tube 240 is set at an angle, which can spray water from the middle of the heat sink to both sides of the heat sink.

[0039] Both U-shaped tube 240 and U-shaped tube 250 are connected to fixed pipes on the side outside the cleaning box 210. Water is delivered into U-shaped tube 240 through the corresponding fixed pipes, and air is delivered into U-shaped tube 250 through the corresponding fixed pipes.

[0040] Example 1

[0041] like Figure 1-2 As shown, in this embodiment, the pressing module 100 includes a fixing base 110, a placement plate 120, a base 130, a top base 140, and a connecting base 150.

[0042] The fixed base 110 is located on one side of the cleaning module 200. Two hydraulic rods 112 are fixedly connected to the top surface of the fixed base 110, and two hydraulic rods 111 are fixedly connected to the bottom surface of the fixed base 110. The output ends of the two hydraulic rods 111 are connected to the bottom surface of the base 130. The bottom hydraulic rods 111 can limit the position of the base 130. The placement plate 120 is fixedly connected to the inner side of the fixed base 110, and the base 130 is located on the inner side of the placement plate 120. Two forming plates 131 are fixedly connected to the top surface of the base 130. The top seat 140 is located on the top of the base 130, and a forming plate 141 is fixedly connected to the bottom surface of the top seat 140. The forming plate 141 corresponds between the two forming plates 131. The connecting seat 150 is fixedly connected to the top surface of the top seat 140. The output ends of the two hydraulic rods 112 are connected to the top surface of the connecting seat 150. The hydraulic rods 112 can adjust the position of the top seat 140 through the connecting seat 150.

[0043] In practice, the two hydraulic rods 112 can drive the connecting seat 150 to move upward, and the connecting seat 150 can drive the top seat 140 and the molding plate 141 to move upward. After the heat sink passes through the cleaning box 210, the heat sink will move to the top of the two molding plates 131. Then, the hydraulic rods 112 can drive the top seat 140 and the molding plate 141 to move downward, so that the molding plate 141 bends part of the heat sink between the two molding plates 131. The bottom surface of the top seat 140 and the top surface of the molding plate 131 squeeze the heat sink, pressing the heat sink into a U-shaped groove. Then, the hydraulic rods 112 can drive the top seat 140 and the molding plate 141 to move upward, and the hydraulic rods 111 can drive the base 130 and the molding plate 141 to move upward. Plate 131 moves downward, causing both forming plate 2141 and forming plate 131 to disengage from the pressed U-shaped grooves. At this point, the heat sink can continue to be conveyed, and the next pressing position is conveyed to the base 130. Then, the base 130 is moved upward by hydraulic rod 111, causing the base 130 and forming plate 131 to move upward to their original positions. Then, hydraulic rod 212 moves the connecting seat 150 and the top seat 140 downward for the next pressing, pressing several U-shaped grooves onto the heat sink. Hydraulic rod 111 moves the base 130 downward, and hydraulic rod 212 moves the top seat 140 upward, causing both forming plate 131 and forming plate 2141 to disengage from the U-shaped grooves. This allows the heat sink to be conveyed smoothly.

[0044] like Figure 3-4As shown, in this embodiment, a connecting shaft 221 is fixedly connected to the inner side of the cleaning rod 220, two conveying rods 260 are rotatably connected to the inner side of the cleaning box 210, a connecting cylinder 261 is fixedly connected to the end of the conveying rod 260, a driving mechanism 280 is provided on the side of the cleaning box 210, a U-shaped tube 270 is fixedly connected to the inner side of the cleaning box 210 and rotatably connected to the inner side of the two conveying rods 260, and the U-shaped tube 270 passes through the inside of the two connecting cylinders 261. A connecting pipe 271 extending into the inside of the cleaning box 210 is fixedly connected to the bottom end of the U-shaped tube 270, and a bottom box 214 is fixedly connected to the bottom surface of the cleaning box 210. A conveying pump is provided inside the bottom box 214, the water outlet of the conveying pump is connected to the bottom end of the connecting pipe 271, and the water inlet of the conveying pump is located inside the cleaning box 210.

[0045] In specific implementation, after the heat sink passes the top of another rotating rod 211, it can pass between two conveying rods 260. The rotation of the two conveying rods 260 can be driven by the drive mechanism 280, and the heat sink is conveyed by the conveying rods 260. After spraying water onto the heat sink to clean its surface, the water can fall onto the filter frame 213, and then pass through the filter frame 213 to fall at the bottom of the cleaning box 210. The water can be filtered through the filter screen inside the filter frame 213. The filtered water can be drawn in from the inlet of the conveying pump, and then the conveying pump delivers the water to the connecting pipe 271. Water from tube 1 can enter the U-shaped tube 270 and then flow out from the top of the U-shaped tube 270. When the water is pressed against the heat sink and a certain amount of heat is generated on the heat sink, part of the heat on the heat sink will be transferred to the heat sink portion of the corresponding U-shaped tube 250 and conveyor rod 260. Since the U-shaped tube 250 and conveyor rod 260 are relatively close to the pressed part of the heat sink, by blowing air onto the heat sink and the water flowing in the U-shaped tube 270, a certain amount of heat on the conveyor rod 260 can be carried away, which can cool the heat sink to a certain extent. This is beneficial for quickly reducing the temperature of the heat sink and reducing the risk of burns.

[0046] Example 2

[0047] Based on Example 1, such as Figure 4-5 As shown, in this embodiment, connecting gears 230 are fixedly sleeved on the sides of both the connecting shaft 221 and the connecting cylinder 261, and two adjacent connecting gears 230 mesh and drive each other. The two connecting cylinders 261 can be linked by the connecting gears 230 on them to make the two connecting cylinders 261 rotate synchronously, and the two connecting shafts 221 can be linked by the connecting gears 230 on them to make the two connecting shafts 221 rotate synchronously.

[0048] The drive mechanism 280 includes a drive box 281, a U-shaped seat 282, a dual-axis motor 283, two transmission shafts 284, and four bevel gears 285;

[0049] The drive box 281 is fixedly connected to the side of the cleaning box 210. The side of the connecting shaft 221 and the side of the connecting cylinder 261 are rotatably connected to the inner side of the drive box 281. The U-shaped seat 282 is fixedly connected to the inner side of the drive box 281. The dual-axis motor 283 is fixedly connected to the inner side of the U-shaped seat 282. The two transmission shafts 284 are rotatably connected to the inner side of the U-shaped seat 282. The U-shaped seat 282 can limit and support the transmission shafts 284. The two output ends of the dual-axis motor 283 are rotatably connected to the ends of the adjacent transmission shafts 284. The four bevel gears 285 are all set inside the drive box 281. The connecting shaft 221 at the top, the connecting cylinder 261 at the top, and the ends of the two transmission shafts 284 are all fixedly sleeved with the adjacent bevel gears 285. The corresponding bevel gears 285 are sleeved on the connecting shaft 221 at the top and the connecting cylinder 261 at the top. The corresponding bevel gears 285 are sleeved on the ends of the two transmission shafts 284. The two adjacent bevel gears 285 mesh and transmit power.

[0050] In specific implementation, the dual-shaft motor 283 can drive two drive shafts 284 to rotate. One drive shaft 284 can drive the top connecting shaft 221 to rotate through two adjacent bevel gears 285, and the other drive shaft 284 can drive the top connecting cylinder 261 to rotate through two adjacent bevel gears 285. The two connecting shafts 221 rotate synchronously through connecting gears 230, and the two connecting cylinders 261 rotate synchronously through connecting gears 230. The connecting cylinder 261 can drive the conveying rod 260 to rotate, so that the conveying rod 260 conveys the heat sink. The connecting shaft 221 can drive the cleaning rod 220 to rotate, so that the cleaning cotton cleans the heat sink. The top connecting shaft 221 and the top connecting cylinder 261 rotate in opposite directions. In this way, while the conveying rod 260 rotates in the forward direction to convey the heat sink, the cleaning cotton can rotate in the reverse direction to clean the surface of the heat sink.
