AI Technical Summary

Technical Problem

Existing bending machine dies are not accurately positioned when processing multi-arc circular surfaces, and the circular surface cannot be adjusted, affecting processing accuracy and stability.

Method used

The system employs four multi-arc circular surface molds and corresponding multi-arc circular surface lower molds. A servo motor drives a bevel gear to adjust the drive gear, thereby achieving the corresponding adjustment between the molds on the multi-arc circular surfaces and the forming groove. The stability of the molds is maintained by the drive gear and the positioning frame.

Benefits of technology

It achieves high-precision machining of multi-arc circular surfaces, improves machining quality, and has a simple mold structure, is easy to operate, and can quickly change molds while maintaining stability.

Abstract

The utility model discloses a bending machine die suitable for multi-radian circular face machining, and belongs to the technical field of bending machines. A bending machine die suitable for multi-radian round face machining comprises an upper support and a lower support, a multi-radian round face upper die is installed in the upper support, a multi-radian round face lower die is connected into the lower support in a sliding mode, and servo motors and bevel gears are installed at the upper end of the upper support and the lower end of the multi-radian round face lower die. The bending machine die solves the problem that an existing bending machine die is inaccurate in radian positioning due to the fact that a boss and a groove are used for machining, the four multi-radian circular face upper dies and the corresponding multi-radian circular face lower dies are adopted, and a bevel gear is driven by a servo motor to adjust a driving gear. The position of the bending head, corresponding to the forming groove, of the upper multi-radian circular face die is adjusted, the structure is simple, operation is convenient, and high-precision bending work is achieved through the precise lower multi-radian circular face die and the corresponding upper multi-radian circular face die.
