Wire breaking mechanism

Abstract

The invention aims to provide a wire breaking mechanism, which is good in pinch-off effect and can avoid the situation that a wire cannot be clamped off. The wire breaking mechanism comprises a mounting base plate, and a tail wire clamping assembly, a vertical wire arranging assembly, a horizontal wire arranging mechanism, a clamping ring assembly, a moving ring assembly and a driving assembly which are connected in sequence and arranged on the mounting base plate, wherein the clamping ring assembly and the moving ring assembly are arranged on the mounting base plate in a sliding manner, the moving ring assembly is in transmission connection with the driving assembly, an induction piece is arranged on the moving ring assembly, a photoelectric switch matched with the induction piece is arranged on the mounting base plate, the photoelectric switch is matched with the clamping ring assembly and the driving assembly, a waste clamping assembly is arranged on one side of the tail wire clamping assembly, the tail wire clamping assembly comprises a fixing plate provided with a wire inlet, an upper pressing block is arranged above the wire inlet, a tail wire clamping air cylinder is arranged below the wire inlet, a lower pressing block is arranged at the output end of the tail wire clamping air cylinder, and a sawtooth groove matched with the lower pressing block is formed in the upperend of the lower pressing block. The wire breaking mechanism can be applied to the technical field of winding machines.

Description

technical field [0001] The invention relates to the technical field of wire winding machines, in particular to a wire breaking mechanism. Background technique [0002] In the existing network transformer manufacturing process, after the T1 ring is wound, the lengths of the four wire heads and the four wire tails are the same, and two suitable twisted wires must be found from the eight wires before proceeding. The winding of the T2 ring needs to be done manually with eyes and hands. It is easy to admit mistakes and cause the product to be unqualified, and it will cause a lot of inconvenience to the subsequent manufacturing process. If the 8 wires are pre-cut before the winding of the T1 ring, and Its length is inconsistent, and then T1 wraps the wire and pulls it off from the pre-cut position, so that the wound T1 ring with inconsistent lengths of the head and tail wires can be obtained, which is conducive to the continuation of the subsequent process.

Problems solved by technology

However, the clamping blocks used in the wire breaking structure of this mechanism are not ideal for the clamping effect of the enameled wire. In the actual work process, the wire may not be clamped, resulting in an error in the length of the wire. Subsequent production has adverse effects, and this problem needs to be resolved
