Abstract
Description
technical field
[0001] The invention belongs to the technical field of low energy consumption, near-net and high-efficiency precision molding. It relates to a blanking machine, especially a pneumatic radial impact blanking machine. The blanking machine adopts the principle of pneumatic impact to realize the circumferential generation, expansion and fracture of fatigue cracks on bars under periodic radial loading, and finally completes Precision blanking. Background technique
[0002] The blanking of metal bars widely exists in the preparation process of cold extrusion, die forging, metal chain pins, rolling bearing rollers, pin standard parts and shaft parts, and in these blanking processes, the amount of blanking is huge, At present, traditional shearing, sawing, high-energy cutting and other blanking methods have problems such as low material utilization rate, large blanking force, high energy consumption, low production efficiency and poor blankin...
