AI Technical Summary

Technical Problem

In the existing CNC bending machine mold fixing device, the two ends of the mold fail to fit and fix effectively during the clamping process, resulting in positional displacement and poor clamping stability.

Method used

The electro-hydraulic servo CNC bending machine uses a quick-clamp mechanism for the mold. Through the rotation of the clamping plates, the elastic pushing of the adapter block, and the movement of the fitting plate, the initial clamping and final fixation of both sides of the mold are achieved. Combined with the use of bolts, it can stably clamp different mold sizes.

Benefits of technology

It improves the clamping stability and adaptability of the mold, ensuring that the mold does not shift position during processing, thereby improving processing accuracy and production efficiency.

Abstract

The utility model discloses an electro-hydraulic servo numerical control bending machine die quick clamping mechanism, and belongs to the field of bending machine die clamping. An electro-hydraulic servo numerical control bending machine mold quick clamping mechanism comprises a base, a pair of first supports is arranged on each of the two sides of the base, a clamping piece is arranged on one side of the outer portion of each first support, the clamping pieces are rotationally connected with the first supports through connecting shafts, and a movable cavity is transversely formed in each clamping piece in a penetrating mode. According to the die fixing device, the problem that the two ends of the die are not attached and clamped in the fixing process of an existing die fixing device of the bending machine is solved, the die blocks can be pressed, the clamping pieces can be made to rotate to achieve primary quick clamping, and when a short die block is completely matched, the die block can be clamped quickly and conveniently. Through the rebound resilience of the first spring and the transverse movement of the adaptive block, the adaptive block can be attached to the side face of the module, and final fixing can be completed after adaptation is conducted after quick clamping.
