Description

Technical Field

[0001] The utility model relates to the technical field of stamping die cooling, in particular to a rapid cooling device for a stamping die. Background Art

[0002] A punch press is a stamping press that can perform blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion, etc. through the cooperation of the movable die and the fixed die. It is widely used in various fields.

[0003] The die of a punching machine moves relative to the workpiece during use and is subject to friction. In the process of continuous stamping, there is no good heat dissipation, which will cause the temperature of the die to rise. Therefore, timely heat dissipation is required. Some punching machines use spray cooling water to cool down, which can easily cause the punching machine track and screws to rust. Some punching machines are equipped with cooling water channels inside the die, but this is a very high test for the structural strength of the die. Some molds will deform due to the presence of cavities after long-term punching. Therefore, it is necessary to design a rapid cooling device for stamping dies to solve the above problems.
