Causes and Hazards of Pressure Concentration in Glasses And Clocks Micro Screws
2026,08,11
During the stretching process, the plastic deformation of the material must overcome frictional resistance and internal stress, resulting in significant uneven stress distribution in
Glasses And Clocks Micro Screws:
1. Excessive Local Load: The unit pressure borne by the contact area between the punch and die (especially the rounded transition area of deep-drawn parts) can reach hundreds of MPa, far exceeding the allowable stress of ordinary steel;
2. Impact of Shape Complexity: For irregularly shaped stretching parts such as automotive body panels, the stress differences between flange edges and sidewalls are large, easily forming stress concentration points;
3. Assembly Clearance in Glasses And Clocks
Micro Screws: If there is a gap between the backing plate and the contact surface of the Glasses And Clocks Micro Screws components (such as the die holder and punch fixing plate), it will lead to a sharp increase in local stress.
The direct consequences of pressure concentration include: cracking of Glasses And Clocks Micro Screws components (such as the die), deformation of the punch, accelerated wear of the backing plate, and the workpiece is prone to local thinning or cracking, seriously affecting production efficiency and product qualification rate.
