Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die cooling device for automobile stamping parts. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts. Some automotive accessories need to be obtained by stamping.

[0003] In large-scale processing operations, the die and punch of the stamping machine will generate high heat, which can easily cause damage to the stamping die, increase processing costs, and affect the quality of workpiece processing. In order to ensure its heat dissipation efficiency, the existing stamping die cooling device usually has more cooling structures. The cost of heat dissipation through coolant is high, and water cooling is prone to overheating of the water, which cannot cool the die well. Utility Model Content

[0004] The utility model aims to provide a stamping die cooling device for automobile stamping parts to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A stamping die cooling device for automobile stamping parts comprises a lower die, an upper die, a mounting frame and a hydraulic rod. The lower die is provided with a lower die built-in groove for filling with coolant, and the upper die is provided with an upper die built-in groove for filling with coolant.

[0007] A heat dissipation fin tube for dissipating heat from the coolant is fixedly connected to one side of the lower mold, and a water outlet end of the heat dissipation fin tube is fixedly connected to a water tank via a water inlet pipe.

[0008] A connecting hose is fixedly connected to one side of the upper mold, a water supply pipe for injecting coolant therein is fixedly connected to the other side of the lower mold, a heat dissipation fan is arranged on one side of the heat dissipation fin tube, and the connecting hose is connected to the water supply pipe.

[0009] The above-mentioned technical scheme is adopted, in which the built-in grooves of the lower mold and the built-in grooves of the upper mold respectively opened in the lower mold and the upper mold can be quickly filled with coolant, so as to cool the lower mold and the upper mold in all directions, and the coolant is collected in the water tank again after the heat is dissipated by the heat dissipation fins for subsequent circulation cooling, thereby ensuring that the temperature of the lower mold and the upper mold will not be too high, thereby improving the service life of the lower mold and the upper mold and ensuring the quality of workpiece processing.

[0010] A further improvement of the technical solution of the utility model is that one end of the connecting hose is connected to one end of the water supply pipe, the other end of the connecting hose is connected to the water inlet end of the radiating fin tube, and the tail end of the water supply pipe is fixedly connected to one side of the water tank through a water pump.

[0011] A further improvement of the technical solution of the utility model is that the inner walls of the lower mold built-in groove and the upper mold built-in groove are respectively fixedly connected with support rods for supporting them.

[0012] A further improvement of the technical solution of the utility model is that: a water channel for conveying coolant is provided on the upper surface of the support rod.

[0013] A further improvement of the technical solution of the utility model is that one side of the heat dissipation fan is fixedly connected to one side of the lower mold, and the heat dissipation fan is used to dissipate heat for the heat dissipation fin tube.

[0014] The above technical solution is adopted, in which the heat dissipation fins and the heat dissipation fan are used in combination, so that the heat absorbed by the lower mold and the upper mold can be quickly replaced with air in the heat dissipation fins for heat dissipation, thereby facilitating the subsequent circulation cooling of the lower mold and the upper mold.

[0015] A further improvement of the technical solution of the utility model is that: a side of the upper mold away from the connecting hose is fixedly connected to the upper surface of the heat dissipating fin tube through an auxiliary hose.

[0016] A further improvement of the technical solution of the utility model is that the bottom end of the mounting frame is fixedly connected to the back side of the lower mold.

[0017] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0018] 1. The utility model provides a stamping die cooling device for automobile stamping parts. By using the lower die built-in groove and the upper die built-in groove respectively opened in the lower die and the upper die, the coolant can be quickly filled into them to cool the lower die and the upper die in all directions. The coolant is collected in the water tank again after the heat is dissipated by the heat dissipation fin tube for subsequent circulation cooling, thereby ensuring that the temperature of the lower die and the upper die will not be too high, improving the service life of the lower die and the upper die, and ensuring the quality of workpiece processing.

[0027] The present invention is further described in detail below in conjunction with the embodiments:

[0028] Example 1

The lower die 1 is provided with a lower die built-in groove 11 for filling with coolant, and the upper die 2 is provided with an upper die built-in groove 12 for filling with coolant.

[0030] A heat dissipation fin tube 5 for dissipating heat from the coolant is fixedly connected to one side of the lower mold 1 , and a water outlet end of the heat dissipation fin tube 5 is fixedly connected to a water tank 7 via a water inlet pipe 6 .

A cooling fan 10 is provided on one side of the heat dissipating fin tube 5, and the connecting hose 13 is connected to the water supply pipe 9.

[0032] One end of the connecting hose 13 is connected to one end of the water supply pipe 9 , and the other end of the connecting hose 13 is connected to the water inlet end of the heat dissipating fin tube 5 . The tail end of the water supply pipe 9 is fixedly connected to one side of the water tank 7 through a water pump 8 .

[0033] Example 2

[0034] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the inner walls of the lower mold built-in groove 11 and the upper mold built-in groove 12 are respectively fixedly connected with support rods 14 for supporting them. The lower mold built-in groove 11 and the upper mold built-in groove 12 respectively opened in the lower mold 1 and the upper mold 2 can quickly fill the coolant therein, and cool the lower mold 1 and the upper mold 2 in all directions, and the coolant is collected in the water tank 7 again after the heat is dissipated by the heat dissipation fin tube 5, and the subsequent circulation cooling work is carried out, so as to ensure that the temperature of the lower mold 1 and the upper mold 2 will not be too high, improve the service life of the lower mold 1 and the upper mold 2, and ensure the quality of workpiece processing.

[0035] A water groove 15 for conveying coolant is provided on the upper surface of the support rod 14. During the stamping process of the lower mold 1 and the upper mold 2, the support rod 14 in the lower mold built-in groove 11 and the upper mold built-in groove 12 supports both of them, thereby improving the structural strength of the lower mold 1 and the upper mold 2. At the same time, the water groove 15 provided on the support rod 14 can facilitate the filling of coolant into the lower mold built-in groove 11 and the upper mold built-in groove 12 to cool both of them.

[0036] Example 3

[0037] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, one side of the heat dissipation fan 10 is fixedly connected to one side of the lower mold 1, and the heat dissipation fan 10 is used to dissipate heat from the heat dissipation fin tube 5. The heat dissipation fin tube 5 and the heat dissipation fan 10 are used in coordination, so that the heat absorbed by the lower mold 1 and the upper mold 2 can be quickly replaced with air in the heat dissipation fin tube 5 to dissipate heat, thereby facilitating subsequent cyclic cooling of the lower mold 1 and the upper mold 2.

[0038] The side of the upper mold 2 away from the connecting hose 13 is fixedly connected to the upper surface of the heat dissipating fin tube 5 through an auxiliary hose.

[0039] The bottom end of the mounting frame 3 is fixedly connected to the back side of the lower mold 1 .

[0040] The working principle of the stamping die cooling device for automobile stamping parts is described in detail below.

[0041] like Figure 1-5 As shown, during use, when the lower mold 1 and the upper mold 2 need to be cooled, the water pump 8 is started to transport the coolant in the water tank 7 to the lower mold built-in groove 11 and the upper mold built-in groove 12 in the lower mold 1 and the upper mold 2 respectively through the water supply pipe 9 and the connecting hose 13 to cool both of them, and the cooled coolant is collected at the inlet of the heat dissipation fin tube 5, and then collected into the water tank 7 through the heat dissipation fin tube 5. The coolant being transported by the heat dissipation fin tube 5 quickly diffuses the heat therein into the air under the blowing of the heat dissipation fan 10 to complete the heat exchange, and then is collected into the water tank 7 through the water inlet pipe 6, and then is transported to the lower mold 1 and the upper mold 2 again through the water supply pipe 9 for cooling.

[0042] During the stamping process of the lower mold 1 and the upper mold 2, the support rods 14 in the lower mold built-in groove 11 and the upper mold built-in groove 12 support the two, thereby improving the structural strength of the lower mold 1 and the upper mold 2. At the same time, the water grooves 15 provided on the support rods 14 can facilitate the filling of coolant into the lower mold built-in groove 11 and the upper mold built-in groove 12 to cool the two.

[0043] The lower mold built-in groove 11 and the upper mold built-in groove 12 match the shapes of the mold cavities of the lower mold 1 and the upper mold 2 .

[0044] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but on the basis of the utility model, some modifications or improvements can be made to it, which is obvious to a general technician in the technical field. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present utility model.
