[0002] In sheet metal mould, the common scheme is to use the punching mode to punch the sheet metal part, and the corresponding shape of sheet metal product is prepared, but for thicker sheet metal, a larger force is needed when punching, and the common way is to increase the stamping pressure, slow down the stamping speed, and set a heating element at the stamping part, because the sheet metal is more likely to deform after heating, so it can be effectively punched.

[0003] For example, in the prior art (announcement number: CN107584026B), a stamping process and corresponding die for sheet metal parts are disclosed, which heats the metal plate to 840-900 DEG C, so that it is completely austenitized, and the internal organization of the metal plate is transformed into austenite and martensite inclusions during cooling to 240-300 DEG C. At this time, stamping is carried out, the required stamping pressure is small, the energy consumption is low, pressure holding cooling is carried out, the size of the sheet metal part is stable, the thickness distribution is uniform, and it is not easy to crack and deform.

[0004] But the freshly punched sheet metal product is very hot and easy to scald the operator, and the punched product will directly fall into the collecting groove, because the sheet metal product is more likely to be bruised or deformed when it is hot, resulting in poor production quality, so it is necessary to design a special cooling structure for the sheet metal mould, so that the sheet metal product can be completely cooled before output.

[0033] As shown in Figures 1-6 The utility model relates to a cooling device for automobile metal mould,

[0034] Including sheet metal mould 1 and sheet metal cooling box 2, sheet metal mould 1 is provided with sheet metal part 3, and sheet metal mould 1 is cut into sheet metal product and is pressed into sheet metal cooling box 2 when stamping sheet metal part 3;

[0035] The inner side of the sheet metal cooling box 2 is provided with a plurality of first clamping devices 4, and the sheet metal products are stacked on the plurality of first clamping devices 4, and the first clamping devices 4 form a heat blocking cavity 5 in the sheet metal cooling box 2;

[0036] The bottom end of the inner side of the sheet metal cooling box 2 is provided with a plurality of second clamping devices 6, and the sheet metal products are stacked on the plurality of second clamping devices 6 after being cooled by the sheet metal cooling box 2;

[0037] The bottom side of the sheet metal cooling box 2 is provided with a product collecting box 7;

[0038] The principle is: sheet metal mold 1 carries out heating and punching on sheet metal part 3, and the sheet metal product can be obtained after punching. The sheet metal mold 1 can punch out the sheet metal product on the sheet metal part 3 one by one. Because the sheet metal mold 1 continuously opens and closes, the punched sheet metal product is stacked together and pressed down into the sheet metal cooling box 2. When the sheet metal product falls to the height of the first clamping device 44, several first clamping devices 4 will hold up the sheet metal product. With the continuous work of the sheet metal mold 1, the sheet metal product will be pressed down below the first clamping device 4. The first clamping device 4 can make the sheet metal product fall into the bottom side of the sheet metal cooling box 2. The heat blocking cavity 5 between the sheet metal cooling box 2 and the first clamping device 4 can separate the adjacent two layers of sheet metal products from each other, thereby realizing the separation of heat transfer between the upper and lower layers. When the sheet metal product is stacked on the second clamping device 6, the second clamping device 6 will gradually lose its function as the number of stacked sheet metal products increases. After the sheet metal product stays in the sheet metal cooling box 2 for a period of time, it can automatically fall into the product collecting box 7. Because the sheet metal product is cooled sufficiently before falling, it is not easy to be damaged or deformed, thereby improving the production quality of the sheet metal product.

[0039] Further, the outer side of the sheet metal cooling box 2 is wrapped with a cooling pipe 8. The two ends of the cooling pipe 8 are connected with a circulating water pump 9 and a cooling water tank 10 through water pipes. The cooling water tank 10 is fixedly installed with a condenser 11. The circulating water pump 9 and the cooling water tank 10 can be connected by water pipes to circulate water cooling for the cooling pipe 8. The temperature of the cooling pipe 8 is reduced by water cooling, and the cooling pipe 8 takes away the heat in the sheet metal cooling box 2. After the sheet metal product is punched, its heat is transferred to the sheet metal cooling box 2 by contact. The cooling pipe 8 cools the sheet metal cooling box 2, so that the sheet metal product can effectively dissipate heat when it stays in the sheet metal cooling box 2 for a certain period of time, thereby avoiding damage to the sheet metal product when it falls back.

[0040] Further, the outer side of the sheet metal cooling box 2 is shaped with a containing cavity 12. The cooling pipe 8 is gap-fitted in the containing cavity 12. The containing cavity 12 is filled with a heat-conducting sealing glue 13.

[0041] Further, the structure of the first clamping device 4 is the same as that of the second clamping device 6, and both include the spring 14 and the clamping steel ball 15; a plurality of spring grooves 16 are formed in the sheet metal cooling box 2, the number of the spring grooves 16 is equal to the sum of the first clamping device 4 and the second clamping device 6, the spring 14 is installed in one-to-one correspondence between the spring groove 16 and the clamping steel ball 15, and the first clamping device 4 and the second clamping device 6 are arranged by clamping the edge of the sheet metal product through the clamping steel ball 15; the spring 14 drives the clamping steel ball 15 to elastically abut against the lower edge of the sheet metal product, so that the vertical rod first clamping device 4 clamps the sheet metal product to form the heat blocking cavity 5, and the second clamping device 6 at the bottom clamps the stacked sheet metal products; when the sheet metal products are stacked to a certain number, the spring 14 loses its effect, so that the sheet metal product at the bottom falls into the product collection groove for recycling, so that the sheet metal products stay in the sheet metal cooling box 2 for a period of time before being output, thereby achieving effective cooling and avoiding product damage.

[0042] Further, the outer end of the spring groove 16 is formed with a limiting ring 17, and the clamping steel ball 15 is clamped in the spring groove 16 through the limiting ring 17; the limiting ring 17 can provide clamping positioning effect for the clamping steel ball 15, so that the clamping steel ball 15 cannot be separated from the spring groove 16, and the stable installation of the first clamping device 4 and the second clamping device 6 is ensured.

[0043] Further, the bottom side of the sheet metal mold 1 is formed with a drawer groove 18, and the product collection box 7 is slidingly fitted and installed in the drawer groove 18; the product collection box 7 is fixedly installed with a pull handle 19 at the front side; the product collection box 7 can be pulled out in a pulling manner, thereby facilitating the recycling of the sheet metal products.

[0044] The embodiment does not limit the shape, material, structure, etc. of the utility model in any form, and any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model are within the protection scope of the utility model technical scheme.
