Feeding device for numerical-control wire bending machine

Abstract

The invention discloses a feeding device for a numerical-control wire bending machine. The feeding device comprises a clamping pushing mechanism and an auxiliary guide mechanism, wherein the clamping pushing mechanism comprises a guide rail base, a lead screw, a sliding block, a feeding rod, a motor base and a motor. The guide rail base is installed on a machine frame, the sliding block axially slides along a wire rod on the guide rail base, the lead screw is fixed on the guide rail base, a lead screw nut is in threaded connection on the lead screw, the lead screw nut 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, the motor is in transmission connection with the lead screw nut, the rear end of the feeding rod is fixed on the motor base, and a wire rod locking mechanism is installed at the front end of the feeding rod. According to the technical scheme, the material feeding rod and the wire rod which is fixedly locked at the front end of the material feeding rod are adopted to enable feeding of the segmented wire rod and wire bending machining to be implemented, synchronous movement of the motor and the sliding block is adopted, ancillary shoring is carried out on a guide mechanism, and the moving feeding precision is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, in particular to a feeding device for 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 ...

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
