Customized precision tungsten steel punch for processing micro-components
Tungsten steel punch processing micro-components are customized with precision tungsten steel punches, and China PTJ Tungsten Steel Processing provides non-standard customized production of precision tungsten steel punches.
Mechanical mold equipment uses more tungsten steel punches, which are often used in stamping, blanking, cutting, punching, turning, riveting, riveting, etc., and the quality, production efficiency and production cost of stamping parts, and mold design It is directly related to the precision and quality of mold parts. The improvement of tool material performance can greatly improve production efficiency. Tungsten steel material has good hardness and strength and is a good choice as a tool material. For micro-component stamping die operations with high precision requirements, tungsten steel punches with better service life and high dimensional accuracy requirements are a good choice for stamping die punch parts.
Tungsten steel punch processing micro-components are customized with precision tungsten steel punches. China PTJ tungsten steel punches are non-standard production, providing tungsten steel square punches, tungsten steel round punches, tungsten steel T-type punches, tungsten steel combined punches A series of tungsten steel die punches, such as tungsten steel punches with holes, tungsten steel blanking punches, tungsten steel cutting punches, tungsten steel internal and external thread punches, tungsten steel riveting punches, etc. are non-standard customized. The precision tungsten steel punches used in this series of micro-components have special requirements. The holes of the tungsten steel punches must be bright and free of sparks. The angle of the hole bottom is an important dimension. Special attention must be paid to the processing. Tiny traces of sparks. Its size specifications are:
1. Φ2.4 tungsten steel punch: Φ6*Φ2.4-4*75°-5°*R0.3-R0.8*35;
2. Φ3.1 tungsten steel punch: Φ6*Φ3.1-5*75°-5°*C0.3-R0.8*35;
3. Φ3.6 tungsten steel punch: Φ6*Φ3.6-5*75°-5°*C0.3-R0.8*35;
4. Φ4.2 tungsten steel punch: Φ8*Φ4.2-5*75°-5°*C0.3-R0.8*35;
5. Φ5.1 tungsten steel punch: Φ8*Φ5.1-5*90°-5°*C0.3-R0.8*35;
6. Φ6.2 tungsten steel punch: Φ10*Φ6.2-5*90°-5°*C0.3-R0.8*35;
7. Φ11 tungsten steel punch: Φ15*Φ11-3*90°-5°*C0.3-R0.8*35;
8. Small tip tungsten steel punch: Φ6*Φ3-0.4-150°*C0.3-C0.5*35;
9. Big tip tungsten steel punch: Φ8*Φ5-0.67-150°*C0.3-C0.5*35.
This series of tungsten steel punches use genuine Chunbao tungsten steel KG7 as the material matrix, and use mirror spark machine discharge punching to meet the requirements of micro-component stamping processing. As a professional manufacturer of tungsten steel in Zhuzhou, China PTJ Cemented Carbide Production Co., Ltd. provides tungsten steel punches to produce precision tungsten steel punches. The dimensional accuracy is consistent and the tolerance meets ±0.002, especially to meet the row size requirements of precision stamping dies. . The tungsten steel punches produced and processed by China PTJ cemented carbide according to customer drawings mainly adopt the following common cemented carbide material parameters:
1. CO content: 10%-20%. ,
2. Density g/cm3: 14.1～14.5.
3. Hardness: 87-92.0HRA. ,
4. Grain size: 0.6-1.2um.
5. Bending strength: 3400-4000MPa. To
6. Elastic modulus GPa: 490.
7. Thermal expansion coefficient 10-6/0C: 5.4. To
8. The dimensions and specifications of the tungsten steel punch are customized according to the drawings, and the accuracy is required to reach ±0.002.
If customers and friends have specific choices for the material usage requirements of tungsten steel punches, we can also make specific choices according to the requirements.
