Stamping die with good durability

Abstract

The invention discloses a stamping die with good durability. The stamping die comprises an upper die base, a lower die base, male dies and female dies, wherein the male dies and the female dies are correspondingly installed on opposite faces of the upper die base and the lower die base, and each male die is matched with the corresponding female die. The upper die base and the lower die base are in a round cake shape. The upper die base and the lower die base are guided through at least three sets of guiding columns and guiding sleeves, wherein the guiding columns and the guiding sleeves are distributed in the circumferential direction of the upper die base and the lower die base at equal intervals and are matched with one another. The number of the mutually matched male dies and female dies is respectively at least three, and the outer surface of each male die and the inner surface of each female die are provided with corrosion resisting layers. According to the stamping die with the good durability, the carrying workload of operators is reduced, the machining cycle is shortened, and working efficiency is improved. Meanwhile, the corrosion resisting layers made of silicon carbide ceramics are adopted, and due to the fact that the corrosion resistance of the silicon carbide ceramics is good, the male dies and the female dies can be effectively prevented from being corroded by acid or alkali or strong oxidizing corrosive powder or granular articles in the process of machining, and the service life of the male dies and the female dies is prolonged.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die with good durability. Background technique [0002] At present, the punching die includes an upper die base, a lower die base, a punching punch, a punching die, a guide, a positioning part, a material part and a buffer part. The buffer part is usually spring or polyurethane rubber. This kind of single-process punching die once Punching can only be done on one profile. If a more complex part has more holes distributed on different profiles, multiple punching is required. This not only increases the workload of the operator, but also has many procedures and a long processing cycle. At the same time, most of the existing molds for stamping corrosive powder or granular substances such as acid, alkali or strong oxidation into sheets or rings are made of die steel or hard alloy. The contact surfaces of corrosive powders or granular substances such as acid, alkali or strong oxidizing ...

This not only increases the workload of the operator, but also has many procedures and a long processing cycle

At the same time, most of the existing molds for stamping corrosive powder or granular substances such as acid, alkali or strong oxidation into sheets or rings are made of die steel or hard alloy. The contact surface of acid, alkali or strong oxidizing powder or granular material is easy to corrode and wear, making the mold unusable
