[0002] In stamping, the special process equipment that can process metal or non-metal materials into parts or semi-finished products is the stamping die, commonly known as a stamping die. Stamping refers to a pressure processing method in which, in a room temperature environment, the material is subjected to force by a die installed on a press, causing the material to separate or plastically deform, and finally obtaining the required part.

[0003] When a stamping die performs multiple impacts on a workpiece, the surface temperature of the die in contact with the workpiece gradually increases. If no cooling measures are taken, the excessively high temperature will cause the die to deform during the impact process, thereby affecting the workpiece processing quality. Therefore, this utility model provides an automotive stamping die with a cooling function to solve the above problems. Utility Model Content

[0016] 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.

[0017] like Figures 1 to 5 As shown, this utility model provides an automotive stamping die with a cooling function, including: a main structure 1, the main structure 1 including a support platform 11, an air outlet 12, a lower stamping die 13, a limiting groove 14, a threaded hole 15, a first cooling pipe 16, a stamping cylinder 18, an upper stamping die 19 and a second cooling pipe 110, and the threaded hole 15 is provided in two sets. Cooling structure 2 includes a cooling sleeve 21, a first heat dissipation fin 22, a second heat dissipation fin 23, a first heat conduction plate 24, a second heat conduction plate 25, a limiting block 26, a through groove 27, and a fixing bolt 28. The through groove 27 and the fixing bolt 28 are provided in two sets. The lower surface of the cooling sleeve 21 is attached to the upper surface of the support platform 11, and the inner wall of the cooling sleeve 21 is slidably attached to the outer wall of the stamping die 13.

[0018] The air outlet 12 is opened through the upper surface of the support platform 11 and is connected to the interior of the support platform 11. A cooling fan is installed inside the support platform 11, and the air outlet of the cooling fan corresponds to the position of the air outlet 12.

[0019] By activating the cooling fan inside the support platform 11, airflow is generated and blown out through the air outlet 12, accelerating the airflow speed inside the first cooling fin 22 and the second cooling fin 23. Utilizing the physical property of hot air rising, the air outlet 12 provides a channel for cold air to enter the interior of the first cooling fin 22 and the second cooling fin 23 in a directional manner, forming a stable airflow loop from bottom to top. This can significantly accelerate the discharge of hot air from the gap between the inner walls of the first cooling fin 22 and the second cooling fin 23. The distance between the first cooling fin 22 and the second cooling fin 23 is 50mm, which can prevent the formation of eddies at the airflow intersection and ensure smooth airflow discharge.

[0020] The lower stamping die 13 is installed at the center of the upper surface of the support platform 11. The limiting groove 14 is opened inside the outer wall of the left and right ends of the lower stamping die 13. Two sets of threaded holes 15 are respectively opened inside the front end surface of the lower stamping die 13. The lower stamping die 13 is provided with a first cooling pipe 16.

[0021] The first cooling pipe 16 can be connected to an external coolant source, and the circulation of coolant inside the first cooling pipe 16 can cool the inside of the stamping die 13.

[0022] Among them, the two ends of the upper surface of the support platform 11 are fixedly connected to the support frame 17, the stamping cylinder 18 is installed at the center of the upper end of the support frame 17, the lower end of the push rod of the stamping cylinder 18 is fixedly connected to the upper surface of the upper stamping die 19, the position of the upper stamping die 19 corresponds to the position of the lower stamping die 13, and the second cooling pipe 110 is arranged inside the upper stamping die 19.

[0023] By activating the stamping cylinder 18, the upper stamping die 19 can be pushed downward. When the upper stamping die 19 and the lower stamping die 13 are in contact, the workpiece can be stamped. The second cooling pipe 110 can be connected to an external coolant source. The circulation of coolant inside the second cooling pipe 110 can cool the inside of the upper stamping die 19. Both the first cooling pipe 16 and the second cooling pipe 110 are arranged in a serpentine pattern with a pipe diameter of Φ10mm. They use G1 / 4 quick connectors and the coolant is a 50% ethylene glycol aqueous solution.

[0024] The first heat dissipation fin 22 is fixedly connected to the front and rear surfaces of the cooling sleeve 21, and the second heat dissipation fin 23 is fixedly connected to the left and right surfaces of the cooling sleeve 21. The positions of the first heat dissipation fin 22 and the second heat dissipation fin 23 correspond to the positions of the air outlet 12. The limiting block 26 is fixedly connected to the inner walls of the left and right sides of the cooling sleeve 21, and the outer wall of the limiting block 26 slides against the inner wall of the limiting groove 14.

[0025] By sliding and fitting the limiting block 26 and the limiting groove 14, the stability of the inner wall of the cooling sleeve 21 when it fits with the outer wall of the stamping die 13 can be improved, and the displacement of the cooling sleeve 21 during use can be effectively avoided.

[0026] The first heat-conducting plate 24 is engaged with the inner walls of the front and rear sides of the cooling sleeve 21, and the second heat-conducting plate 25 is engaged with the inner walls of the left and right sides of the cooling sleeve 21. The first heat-conducting plate 24 and the second heat-conducting plate 25 are respectively attached to the outer walls around the stamping die 13. The position of the first heat-conducting plate 24 corresponds to the position of the first heat dissipation fin 22, and the position of the second heat-conducting plate 25 corresponds to the position of the second heat dissipation fin 23.

[0027] Both the first heat-conducting plate 24 and the second heat-conducting plate 25 are filled with graphene and aluminum alloy composite powder. The ultra-high thermal conductivity of graphene (5000 W / (m·K)) makes the thermal conductivity of the first heat-conducting plate 24 and the second heat-conducting plate 25 reach 650-700 W / (m·K), which can significantly accelerate the heat conduction rate of the outer wall of the stamping die 13. Furthermore, the heat absorbed by the first heat-conducting plate 24 and the second heat-conducting plate 25 will be quickly dissipated through the first heat dissipation fin 22 and the second heat dissipation fin 23. In the first heat-conducting plate 24 and the second heat-conducting plate 25, the mass ratio of graphene to aluminum alloy is 8%:92%, and they are prepared using powder metallurgy technology.

[0028] Among them, two sets of through grooves 27 respectively penetrate the interior of both ends of the front surface of the cooling sleeve 21, two sets of fixing bolts 28 respectively penetrate the interior of both ends of the front surface of the cooling sleeve 21, and the two sets of fixing bolts 28 are respectively connected to the internal threads of the two sets of threaded holes 15.

[0029] The two sets of through slots 27 ensure that the cooling sleeve 21 will not interfere with the first cooling pipe 16 when connected to the stamping die 13. The two sets of fixing bolts 28 and the threaded connection of the threaded holes 15 allow the operator to quickly install and disassemble the cooling structure 2.

[0030] The working principle and usage process of this utility model are as follows: First, the cooling sleeve 21 is attached to the upper surface of the support platform 11, so that the inner wall of the cooling sleeve 21 is attached to the outer wall of the stamping die 13. Then, the cooling structure 2 is fixed by threading the fixing bolts 28 and threaded holes 15. Next, the first cooling pipe 16 and the second cooling pipe 110 are connected to an external coolant source, and the cooling fan inside the support platform 11 is started. Then, the stamping cylinder 18 is started, and its push rod drives the upper stamping die 19 downwards, cooperating with the lower stamping die 13 to complete the workpiece stamping. During the pressing process, the coolant circulating in the first cooling pipe 16 and the second cooling pipe 110 cools the interior of the lower stamping die 13 and the upper stamping die 19, respectively. The first heat-conducting plate 24 and the second heat-conducting plate 25 absorb the heat from the outer wall of the lower stamping die 13 and transfer it to the first heat dissipation fin 22 and the second heat dissipation fin 23. The airflow generated by the cooling fan accelerates the heat dissipation of the fins through the air outlet 12. If it is necessary to maintain or replace the cooling structure 2, rotate the fixing bolt 28 to disengage it from the threaded hole 15, and pull the cooling sleeve 21 to remove it from the outer wall of the lower stamping die 13.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the cooling fan and the stamping cylinder 18 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
