Sipxmach Fine blanking stamping introduction
Sipxmach is fine blanking companies in China.
Our products’ equipment and engineers are optimized for Automobile and furniture custom metal High precison stamping production.
Quality standard: TS16949 and ISO9001.
Our custom metal finestamping service uses a combination of 80tons, 150tons, 300tons, 450tons, 600tons, 800tons, 1000tons presses to provide the most cost-effective solution for high volume manufacturing.
Typical fine-blanking tool is a single-station compound tool for producing a finished part in one press stroke.
The only addition operation needed is the removal of a slight burr.
The process requires a triple-action fine-blanking press.
Closing force, counterpressure, and blanking pressure forces are individually and infinitely adjustable.
Fineblanking provides no fracture zone shearing. This is accomplished by compressing the entire portion and then extracting the blank from an upper and lower punch. This enables the process to maintain very narrow tolerances and possibly eliminate secondary activities
How fine blanking works?
Fine blanking aims to increase the length of the shear zone and decrease the torn zone during the blanking process. Fine blanking also can decrease the height of burrs. Now almost all stamping factories are trying to improve metal stamping products quality and through some simple ways to achieve precision fine blanking’s effect.
A typical sheared surface of fine blanking
Generally, the clearance between upper and bottom die of the blanking tool determine the dimension tolerance accuracy. Smaller clearance means fine blanking tools will be wearing more quickly. You should find the balance between good appearance with precision dimensions and the life of the tool. The tooling of fine blanking clearance will affect the final stamped part burrs height. Hope the following picture of a stamping factory experience will help you understand what is fine blanking, and what difference between fine blanking and common punching and blanking process for sheet metal parts.
