AI Technical Summary
The clamping structure for existing box profile bending machines cannot move during the bending process of metal material, resulting in the metal material being easily disconnected from the limiting plate and affecting the bending effect.
An adjustable clamping structure for bending machines is designed, including a moving clamping mechanism and a limiting mechanism. The moving clamping mechanism drives the first threaded rod to rotate through the motor, drives the threaded plate and the extruded block to move, adjusts the distance between the U-shaped plate, and ensures stable clamping of the metal parts. The limiting mechanism prevents the metal parts from breaking away from the U-shaped plate through the fitting of the insert rod and the spring.
The clamping structure can be adjusted according to the length and bending range of the metal part, ensuring that the metal part is more stable during the bending process, avoiding breaking away from the limiting plate, and improving the bending effect.
