Circulation cooling device for stamping die and stamping die

Abstract

The invention provides a circulation cooling device for a stamping die and a stamping die, including a working box, a first cooling tank, a condensation chamber, a stamping lower die, a stamping upper die, and a second cooling tank. When the switch detects that the temperature of the stamping upper die exceeds the set value, it will control the first electromagnet and the second electromagnet to turn on or off alternately, so that the stamping upper die in the first installation groove and the second installation groove work alternately, without stopping to cool down Or replace the stamping upper die, which effectively improves the work efficiency, and the coolant in the first cooling tank and the second cooling tank will absorb heat and vaporize due to heat absorption or pressure reduction, which greatly improves the cooling efficiency of the coolant , The setting of the heat sink makes the heat conduction efficiency of the stamping lower die and the stamping upper die better, and the heat dissipation is more uniform, and the coolant contacts the heat sink, so that the coolant can absorb heat faster and effectively improve the heat dissipation efficiency.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a circulating cooling device for stamping dies and a stamping die. Background technique [0002] Stamping is a pressure processing method that uses a die installed on a press to apply pressure to a material at room temperature to separate or plastically deform it to obtain the desired parts. Stamping die is a special process equipment for processing materials into parts (or semi-finished products) in cold stamping process. Heat will be generated during the stamping process, which will cause the temperature of the workpiece and the mold to rise, and it is necessary to cool the workpiece and the mold. , to prevent the high temperature from affecting the performance of the workpiece, as well as damage to the mold, shorten the service life of the mold, and reduce the quality of the workpiece. [0003] Publication number CN211588271U provides a stamping die with self-cooling fu...

AI Technical Summary

Problems solved by technology

[0005] During the use of the above-mentioned device, the stamping head generates heat due to friction during the stamping process, and the coolant absorbs heat during the stamping process of the stamping head, but it is difficult for the coolant to dissipate the heat in the stamping head during the continuous stamping process of the stamping head Complete absorption, when the heat in the punching head accumulates more and more, it is very easy to damage the punching head, at this time, stop the machine to cool down or replace the punching head, this process will reduce work efficiency
