Numerical control wire bending machine

Abstract

The invention discloses a numerical control wire bending machine which comprises a machine frame. A handpiece, a handpiece rotating mechanism and a feeding device are sequentially arranged on the machine frame from front to back. The feeding device comprises a clamping and pushing mechanism and an auxiliary guide mechanism. The clamping and pushing mechanism comprises a guide rail base, a screw rod, a sliding block, a feeding rod, a motor base and a motor, the guide rail base is installed on the machine frame, the sliding block axially slides on the guide rail base along wires, the screw rod is fixed on the guide rail base and is in threaded connection with a screw rod nut which is installed on the sliding block through a bearing, the motor base is fixedly installed on the sliding block, the motor is installed on the motor base and is in transmission connection with the screw rod nut, the rear end of the feeding rod is fixed to the motor base, and a wire locking mechanism is installed at the front end of the feeding rod. According to the technical scheme, the feeding rod and the front end of the feeding rod are adopted for locking and fixing wires, so that feeding and wire bending processing of sectioned wires can be implemented; the motor and the sliding block move synchronously, and the auxiliary supporting guide mechanism is adopted, so precision of movable feeding is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, in particular to a numerically controlled wire bending machine. Background technique [0002] The patent documents whose publication numbers are CN201231294Y and CN101716636A respectively disclose two kinds of numerically controlled wire bending machines. Their structures are similar, and they are all used for bending wire forming of continuous wires (such as steel wire coils), including a frame on which there are Straightening mechanism, wire feeding mechanism, machine head rotation mechanism, machine head, cutting mechanism, mold, mold rotation mechanism, mold conversion mechanism and control unit. However, there is no wire bending machine that bends wire rods section by section in the prior art. The problem that the continuous wire bending machine cannot be directly used to bend the segmented wire is: first, the existing feeding mechanism cannot realize the feeding of the segmen...

AI Technical Summary

Problems solved by technology

However, in the prior art, there is no wire bending machine that bends wire rods section by section.

The problem that the continuous wire bending machine cannot be directly used to bend the segmented wire is: first, the existing feeding mechanism cannot realize the feeding of the segmented wire; It is difficult to insert into the hole; the third is that when the bent wire is formed, the segmented wire cannot be reliably clamped and fixed, which affects the quality of the bent wire
