Problems solved by technology

The frictional heat generated by stamping will increase the temperature of the stamping die. Due to the high stamping speed of the high-speed stamping die, the temperature of the high-speed stamping die will be much higher than the temperature of the general fixture. High temperature will cause the workpiece and the high-speed stamping die itself to deform due to heat. The error will have a greater impact on the accuracy of high-speed stamping, and the high-speed stamping die itself will be easily damaged and scrapped due to high temperature

Abstract

The invention discloses a high speed stamping die with a cooling structure. The high speed stamping die is internally equipped with a cooling pipeline; a cooling liquid circulates in the cooling pipeline, the initial end of the cooling pipeline is a cooling liquid inlet, and the terminal end of the cooling pipeline is a cooling liquid outlet; and the high speed stamping die is also internally equipped with a temperature sensor for monitoring the temperature in the high speed stamping die. In the invention, the cooling liquid in the cooling pipeline can immediately conduct heat generated during the stamping process out of the high speed stamping die by utilizing a heat exchange mode so as to lower the temperature in the high speed stamping die; and a control device controls an infusion pump to adjust flow of the cooling liquid according to temperature information monitored by the temperature sensor so as to keep the temperature in the high speed stamping die within a certain range. Therefore, the high speed stamping die has the beneficial effects that the deformation and damage of the high speed stamping die are reduced and the service life of the high speed stamping die is prolonged while the stamping precision and production efficiency are ensured.

Description

technical field [0001] The invention relates to a structural improvement of a stamping die, in particular to a high-speed stamping die with a cooling function. Background technique [0002] Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of the processed parts are directly related to the design and manufacture of stamping dies. The frictional heat generated by stamping will increase the temperature of the stamping die. Due to the high stamping speed of the high-speed stamping die, the temperature of the high-speed stamping die will be much higher than the temperature of the general fixture. High temperature will cause the workpiece and the high-speed stamping die itself to deform due to heat. The error will have a greater impact on the accuracy of high-speed stamping, and the high-speed stamping die itself will be easily damaged and scrapped due to hi...
