Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a cooling device for metal processing. Background Technology

[0002] Metal processing refers to the production activities carried out by humans to process materials with metallic properties, which are composed mainly of metallic elements. When processing metals, it is necessary to cool the metal workpieces.

[0003] Cooling devices are generally cooled by air or water. After prolonged use, the internal coolant temperature of water-cooled devices rises, requiring replacement with new coolant. This makes it inconvenient to circulate the coolant, resulting in a significant waste of resources. Air cooling, on the other hand, has low efficiency, affecting processing efficiency. Therefore, there is a lack of cooling devices that combine liquid and air cooling.

[0004] Therefore, we have made improvements to this and proposed a cooling device for metal processing. Utility Model Content

[0005] The present invention aims to address the shortcomings of the prior art by providing a cooling device for metal processing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a cooling device for metal processing, comprising a cooling tank, and further comprising: a frame, installed on the top of the cooling tank; a reciprocating lifting mechanism, installed on the frame; a hollow box, installed on the lifting end of the reciprocating lifting mechanism, for holding metal parts to be cooled; a circulating heat exchange tube, wherein the outer side wall of the cooling tank near the top and bottom ends is respectively provided with uniformly distributed upper guide holes and lower guide holes, and both ends of the circulating heat exchange tube are respectively connected to the upper guide holes and lower guide holes; a piston plate, slidably connected to the inner side wall of the cooling tank, and the piston plate is provided with a return hole; and a transmission assembly, connected between the cooling tank and the piston plate, for controlling the lifting and lowering of the piston plate.

[0007] As a preferred technical solution of this utility model, it also includes a heat dissipation fan installed on the frame and facing the hollow box.

[0008] As a preferred technical solution of this utility model, the outer wall of the circulating heat exchange tube is also fixedly connected with uniformly distributed heat dissipation fins.

[0009] As a preferred technical solution of this utility model, the reciprocating lifting mechanism includes a fixed box fixedly installed in the middle of the frame, a drive shaft is provided on the side wall of the fixed box, a turntable is fixedly connected to the output end of the drive shaft, a locking block is fixedly provided on the outer wall of the turntable, a T-shaped rod is slidably connected to the outer wall of the locking block, the middle section of the T-shaped rod passes through a limiting frame installed at the bottom of the fixed box, and the reciprocating end of the T-shaped rod is fixedly connected to the hollow box.

[0010] As a preferred technical solution of this utility model, a protective shell is fixedly installed on the side wall of the fixed box, and the protective shell covers the output end of the drive shaft.

[0011] As a preferred technical solution of this utility model, the transmission assembly includes a fixed plate fixedly installed at the bottom of the inner cavity of the cooling tank, symmetrically distributed telescopic rods fixedly arranged between the piston plate and the fixed plate, uniformly distributed springs fixedly installed on the top of the fixed plate, the top end of the springs being fixedly connected to the piston plate, and uniformly distributed piston rods fixedly installed on the top of the fixed plate, with the springs sleeved on the outer wall of the piston rods.

[0012] As a preferred technical solution of this utility model, a traction rope is fixedly connected to the bottom of the hollow box. When the traction rope is in a relaxed state, the length of the spring is greater than the length of the piston rod, and a tie ring is also fixedly installed on the top of the fixed plate.

[0014] 1. The reciprocating lifting mechanism drives the hollow box to rise and fall within the cooling tank cavity. In conjunction with the heat dissipation fan on the frame, it facilitates the cooling of the metal workpiece inside the hollow box cavity, solving the problem in the prior art that it is not convenient to combine liquid cooling and air cooling.

[0015] 2. By using a reciprocating lifting mechanism to tighten or loosen the traction rope at the bottom of the hollow box, the coolant at the bottom of the cooling tank can be cooled before flowing into the top of the tank. This solves the problem in existing water-cooling devices where the internal coolant temperature rises after prolonged use, requiring replacement of the coolant and making it inconvenient to recycle the coolant.

[0025] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] like Figures 1 to 7 As shown, a cooling device for metal processing includes a cooling tank 1, and further includes: a frame 2, installed on the top of the cooling tank 1; a reciprocating lifting mechanism 3, installed on the frame 2; a hollow box 4, installed on the lifting end of the reciprocating lifting mechanism 3, for holding metal parts to be cooled; a circulating heat exchange pipe 5, with uniformly distributed upper and lower guide holes respectively opened on the outer side wall of the cooling tank 1 near the top and bottom ends, and both ends of the circulating heat exchange pipe 5 communicating with the upper and lower guide holes respectively; a piston plate 6, slidably connected to the inner side wall of the cooling tank 1, and with a return hole 7 opened on the piston plate 6; and a transmission assembly 8, connected between the cooling tank 1 and the piston plate 6, for controlling the lifting and lowering of the piston plate 6, facilitating the circulation of coolant and avoiding resource waste.

[0028] As a preferred embodiment, based on the above method, it further includes a heat dissipation fan 9 installed on the frame 2 and facing the hollow box 4, which facilitates the combined use of liquid cooling and air cooling, facilitates evaporative heat dissipation from the workpiece surface, and greatly improves heat exchange efficiency.

[0029] In a preferred embodiment, based on the above method, the outer wall of the circulating heat exchange tube 5 is further fixedly connected with uniformly distributed heat dissipation fins 501, which dissipate heat from the coolant inside the circulating heat exchange tube 5 through the heat dissipation fins 501.

[0030] As a preferred embodiment, based on the above method, the reciprocating lifting mechanism 3 further includes a fixed box 301 fixedly installed in the middle of the frame 2. A drive shaft 302 is provided on the side wall of the fixed box 301. A turntable 303 is fixedly connected to the output end of the drive shaft 302. A locking block 304 is fixedly provided on the outer wall of the turntable 303. A T-shaped rod 305 is slidably connected to the outer wall of the locking block 304. The middle section of the T-shaped rod 305 passes through the limiting frame 306 installed at the bottom of the fixed box 301. The reciprocating end of the T-shaped rod 305 is fixedly connected to the hollow box 4, which facilitates the hollow box 4 to reciprocate in the inner cavity of the cooling barrel 1.

[0031] As a preferred embodiment, based on the above method, a protective shell 307 is further fixedly installed on the side wall of the fixed box 301. The protective shell 307 covers the output end of the drive shaft 302, which facilitates the protection of the output end of the drive shaft 302.

[0032] In a preferred embodiment, based on the above method, the transmission assembly 8 further includes a fixed plate 801 fixedly installed at the bottom of the inner cavity of the cooling tank 1, symmetrically distributed telescopic rods 802 fixedly arranged between the piston plate 6 and the fixed plate 801, uniformly distributed springs 803 fixedly installed on the top of the fixed plate 801, the top end of the springs 803 being fixedly connected to the piston plate 6, and uniformly distributed piston rods 804 fixedly installed on the top of the fixed plate 801, with the springs 803 sleeved on the outer wall of the piston rods 804. The rebound force of the springs 803 drives the piston plate 6 to reset, so that the coolant flows into the position between the piston plate 6 and the fixed plate 801 through the return hole 7 opened on the piston plate 6.

[0033] As a preferred embodiment, based on the above method, a traction rope 10 is further fixedly connected to the bottom of the hollow box 4. When the traction rope 10 is in a relaxed state, the length of the spring 803 is greater than the length of the piston rod 804. A tie ring 805 is also fixedly installed on the top of the fixed plate 801. The traction rope 10 extends downward through the piston plate 6, and the extended end of the traction rope 10 passes through the tie ring 805 on the top of the fixed plate 801 and is fixed to the bottom of the piston plate 6. This facilitates the recycling of coolant and avoids resource waste.

[0034] Specifically, when using this metal processing cooling device: first, place the metal workpiece to be cooled inside the hollow box 4 to facilitate subsequent cooling;

[0035] The drive shaft 302 drives the turntable 303 to rotate. At this time, the locking block 304 installed on the turntable 303 drives the T-shaped rod 305 to reciprocate, which facilitates the hollow box 4 installed on the reciprocating end of the T-shaped rod 305 to reciprocate in the inner cavity of the cooling tank 1. When the hollow box 4 and the cooling fan 9 are in a horizontal position, the cooling fan 9 can easily cool the metal workpiece inside the hollow box 4. The coolant on the metal workpiece evaporates and carries away the heat, which facilitates the combination of liquid cooling and air cooling and improves the cooling effect.

[0036] When the T-shaped rod 305 moves the hollow box 4 upward, the traction rope 10 fixed at the bottom of the hollow box 4 tightens, and the piston plate 6 moves closer to the fixed plate 801, so that the coolant between the piston plate 6 and the fixed plate 801 can be discharged into the inner cavity of the circulating heat exchange tube 5 through the lower guide hole. The coolant in the inner cavity of the circulating heat exchange tube 5 is cooled by the heat dissipation fins 501. After the heat dissipation treatment, the coolant is discharged back into the inner cavity of the cooling tank 1 through the upper guide hole, so that the coolant can be recycled and used, avoiding waste of resources.

[0037] When the T-shaped rod 305 moves the hollow box 4 downward, the traction rope 10 is in a relaxed state. At this time, the piston plate 6 is reset by the rebound force of the spring 803, so that the coolant flows into the position between the piston plate 6 and the fixed plate 801 through the return hole 7 opened on the piston plate 6.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
