[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a stamping die installed on a punch press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the required parts. Stamping dies are one of the main equipment used to produce various hardware products.

[0003] Punching oil is a metal processing oil made of sulphurized lard as the main agent, with various additives such as refined oiliness agent and rust inhibitor added. It is particularly suitable for high-intensity operations such as punching, shearing, punching, punching, tapping, and grooving. At present, before the stamping die is used to stamp the metal workpiece, it is necessary to spray the stamping die and the metal workpiece with punching oil to avoid scratches on the surface of the metal workpiece caused by the punch during stamping, and also to protect the punch.

[0004] In the prior art, the stamping die and metal workpiece are mainly sprayed with punching and shearing oil manually, which is very time-consuming and labor-intensive, and has very low production efficiency. Therefore, it is necessary to study a solution to solve the above problem. Utility Model Content
