Audited Supplier Carbide sharpening needle
Carbide progressive stamping die blunt needle is used in batch production, one of the common blunt needle carbide namely tungsten steel blunt blunt needle, also known as the punch, blunt rods or punch, continuous is installed on the stamping die blanking punching thrust homework make processed material separation or plastic deformation to obtain the finished or semi-finished products need mould parts. Carbide blunt needle with acid and alkali corrosion resistance to wear and not rust excellent properties, such as the pharmaceutical industry chosen its punch to make stamping tablets, stamping is installed on the pressure mold at room temperature to pressure on the material, make its produce a separation or plastic deformation, a processing method to obtain the required parts, are common in the industrial production. Stamping die is an indispensable process equipment for stamping production and is a technology-intensive product. The quality of stamping parts, production efficiency and production cost are directly related to mold design and precision quality of mold parts. Punching needle, as the core part of stamping die, is a replaceable die consumable product. For high requirements of stamping workpiece must be used tungsten steel punching needle, the hardness of tungsten steel in the following 90 and more than 80, if the use of other materials punching needle is easy to wear. The second key is the gap between the convex and concave die can be amplified as far as possible to reduce the resistance of the punch. Cemented carbide punching needle customized focus is the accuracy and consistency of the product. Taking the customized YG10X cemented carbide punching needle as an example, its physical parameters are described as follows:
CO content: 10%-20%. Density g/cm3:14.0-14.5g /cm3; Hardness: 87-92.0HRA. Grain size: 0.6-1.2um.
Bending strength: 4000MPa. Elastic modulus GPa: 490. Thermal expansion coefficient 10-6/0C: 5.4. The dimensions and specifications of cemented carbide punch are customized according to drawings, and the accuracy can reach ±0.001mm
