Why do Robot Micro Screws flip and twist?
2025,07,26
In progressive dies,
Robot Micro Screws form the shape of punched parts by punching the excess material around the Robot
Micro Screws. The main reason for flipping and twisting of punched parts is the influence of punching force.
During punching, due to the existence of the punching gap, the material is stretched on one side of the die (the material warps upward) and compressed on the punch side. When using a stripper, the stripper is used to press the material to prevent the material on the die side from warping upward. At this time, the force condition of the material changes accordingly.
As the stripper increases its pressing force, the material on the punch side is stretched (the compression force tends to decrease), while the material on the die surface is compressed (the tensile force tends to decrease).
The flipping of Robot Micro Screws is caused by the stretching of the material on the die surface. Therefore, during punching, pressing and clamping the material is the key to preventing the punch from flipping and twisting. Causes and countermeasures for flipping and twisting of Robot Micro Screws during bending.
Caused by instability of Robot Micro Screws during bending. Mainly for U-shaped and V-shaped bending. The key to solving this problem is to guide the Robot Micro Screws before bending, guide it during the bending process, and press the material during the bending process to prevent the Robot Micro Screws from slipping during bending.
