Technical Field

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

[0002] A stamping die is a special process equipment that processes materials into parts in cold stamping processing, called a cold stamping die. Stamping is a pressure processing method that applies pressure to materials using a die installed on a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts. The materials for manufacturing stamping dies include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low-melting-point alloy, aluminum bronze, polymer materials, and so on.

[0003] Automobile stamping parts are metal stamping parts that make up automobile components. Among automobile stamping parts, some directly become automobile components after stamping, and some need to go through processes such as welding, machining, or painting after stamping before becoming automobile components. In the production of stamping parts, stamping dies are generally used. The long-term use of stamping dies will cause the temperature of the stamping seat to rise. The prior art generally arranges cooling water pipes in the stamping seat for temperature reduction. However, the installation process of arranging cooling water pipes in the stamping seat is troublesome, and maintenance and replacement are not very convenient. Moreover, during temperature reduction, the arranged water pipes cannot contact the entire stamping seat, resulting in a low temperature reduction rate. Therefore, it is necessary to design a cooling device to solve the above problems. Content of the Utility Model

[0004] According to the above existing technical problems, the utility model provides a cooling device for an automobile stamping die for stamping parts, which is characterized by including a bottom plate, a fixing plate, a stamping hydraulic cylinder, a moving plate, a stamping block, a fixing seat, a stamping seat, a limiting column, a support frame, an electric telescopic rod, a mounting plate, a nozzle, a water delivery pipe, a water pump, and a water tank.

[0005] One end of the bottom plate is fixedly connected to the fixing plate. The stamping hydraulic cylinder is installed on the fixing plate. The telescopic end of the stamping hydraulic cylinder passes through the fixing plate and extends to be connected to the moving plate. The stamping block is installed on the moving plate. The four corners of the moving plate are penetrated and connected by the limiting columns.
