Numerical control wire bending machine

Abstract

The invention discloses a numerical control wire bending machine which comprises a machine frame. The machine frame is provided with a machine head, a machine head rotating mechanism and a feeding device from front to back in sequence. The feeding device comprises a clamping pushing mechanism and an auxiliary guiding mechanism. The clamping 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 slides on the guide rail base along wires in the axial direction. The screw rod is fixed to the guide rail base. A feed screw nut is connected to the screw rod in a threaded mode and is installed on the sliding block through a bearing, and the motor base is fixedly installed on the sliding block. The motor is installed on the motor base. The motor is connected with the feed screw nut in a transmitting mode. The rear end of the feeding rod is fixed to the motor base. 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 used for locking and fixing the wires so that feeding of sectioned wires and wire bending can be achieved, synchronous motion of the motor and the sliding block is adopted, and the auxiliary supporting guiding mechanism is adopted, so that the movable feeding accuracy is improved.

Background technique [0008] 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, mo...

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
