Hard Alloy Punching Rod Bar
Hard alloy punching rod, also known as tungsten steel punching rod, also known as punch, needle or punch, is installed on a stamping die for continuous punching and cutting operations, causing the processed material to separate or undergo plastic deformation, thereby obtaining the desired finished or semi-finished product. The acid and alkali resistance, corrosion resistance, and non rusting performance of hard alloy punch rods are specially selected by the pharmaceutical industry for the production of punch heads for stamping tablets
Tungsten Carbide Thimble Carbide Punching Pin
① Density g/cm3: 14.5
② Hardness HRA: 91.5
③ Co content: 10%
④ Grain size: 1.0um
⑤ Bending strength N/mm2: ≥ 2800
⑥ Thermal expansion coefficient 10-6/0C: 4.9
⑦ Elastic modulus GPa: 525
Hard alloy punch rods used in stamping molds in industrial production can be made into different shapes according to the different needs of the product, and can be used for batch hole processing. Especially in the production of complete sets of progressive molds, such as computer cases, there are many heat dissipation holes on them, as well as mobile phones, many electrical appliances, and machinery. Ordinary drilling machines, lathes, and milling machines can only process circular holes, which is quite inefficient. When stamping, large punch presses can process hundreds of holes in just a few seconds, significantly improving the efficiency of large-scale production. Especially for large-scale production operations of automated precision machine tools, the precision and quality of parts produced by stamping have been greatly improved.
