The die punch pin is an indispensable accessory for the working of the stamping die. It is a replaceable mold consumable. It is mounted on the stamping die for continuous punching and punching operations, so that the material to be processed is separated or plastically deformed, thereby obtaining the required Finished or semi-finished products.According to the different materials, the punch pin can be divided into SKD punching pin/SKH punching pin/ASP punching pin.SKD punching pins are made of SKD special mold steel.

 

They can have different shapes according to the needs of production.SKH punch pins, ASP punch pins, tungsten steel punch pins and high-speed steel punch pins have different appearances due to different materials.

Die punch pin manufacturing process
1. Drawing, cutting

The raw materials that have passed the test are drawn into a desired diameter size by a wire drawing machine, and then cut into a rod-shaped punching pin blank of a fixed length.
2. Heat treatment
Before the heat treatment, the punching blank is firstly straightened on the straightening platform with a dial gauge, and then placed in a high-frequency electric furnace or a salt bath furnace to be heated to 800-1300 degrees Celsius for 2 to 5 minutes. After oil quenching and hardening, the tip hardness of the quenching heat treatment can reach Hv590-800. Then the low temperature tempering treatment is carried out.
3. Grinding processing
The punching pin is clamped on the spring collet of the machine tool, and the grinding forming process is separately performed according to the angular requirements of the various needle bases of the punching pin.
4. Polishing
Polishing is to clean the surface of the oil, rust, etc., and clean the surface.
5. Inspection, storage
According to the required index, the qualified ones can be packed into the warehouse.
