The rotary thimble manufacturer will let you know: tungsten steel punching needle. Tungsten steel punching needles can be made into punching needles of different shapes according to the different needs of products for mass hole processing. For example, there are many cooling holes on the computer chassis, as well as mobile phones, many electrical appliances and machinery. However, when processed with ordinary drilling machines, turning and milling machines, only round holes can be processed, and the efficiency is quite low. When stamping, it takes less than a second for a large punch to process hundreds of holes at the same time, which greatly improves the production efficiency.
1. Introduction of rotary thimble manufacturer: characteristics of tungsten steel punching needle
High hardness (hrc90), batch punching, improving production efficiency. Tungsten steel punching needles are mostly used in punching machines, which can punch various types and shapes of holes.
2. Selection of tungsten steel punching needle material
Different tungsten steels shall be selected for punching needles according to different punching materials and thicknesses. Generally, the thicker the product to be punched, the lower the hardness and the better the toughness of the tungsten steel shall be selected. The harder the material is, the lower the hardness of tungsten steel is, so that the punching needle can be effectively avoided. For punching thin plates or those with low hardness, tungsten steel punching needles with higher hardness can be used for hole processing of such products, which can improve the service life of punching needles.
3. Types of punches
According to different material selection, punching needles can be divided into SKD punching needles, SKH punching needles and ASP punching needles. SKD punching needles are punching needles made of SKD special die steel. According to the needs of production, there can be various shapes on the appearance. SKH punching needle, ASP punching needle, tungsten steel punching needle and high-speed steel punching needle are different in appearance because of their different materials. The tungsten steel punching needle looks black, while the high-speed steel punching needle is brighter.
The guiding punch is also called guiding punch for short. According to the needs of the stamping machine, it can have various shapes, such as a type, B type, Hb type, TAPP type, tbpp type, etc.
The child mother punch is also called the child mother punch for short. There is a small protrusion on the top of the punch. I don't know the origin of the name. Maybe it is because of the protrusion on the top of the punch. The letter punching needle can be divided into standard type a type jsbp type and other models.
There are also tooth extraction punch, inspection tip, hexagonal punch, elliptical punch, forming punch, fan punch, special-shaped punch, high-speed steel punch, tungsten steel punch, etc.
