Flying shear type high-speed wire cutting device

Abstract

The invention discloses a flying shear type high-speed wire cutting device, which consists of an auxiliary wire feeding mechanism, a high-speed wire cutting mechanism, a baiting machine and a storage tank, wherein the high-speed wire cutting mechanism comprises a wire feeder, a straightening machine and a fly-cutter shearer; the wire feeder consists of wire feeding wheels with the same rotating speed and opposite directions; the straightening machine consists of a rotating hub and a belt transmission mechanism, and a hole die is arranged in the rotating hub; and the fly-cutter shearer consists of an upper cutter head and a lower cutter head with the same rotating speed and opposite directions, and cut-off blades are arranged in cutter head grooves. The flying shear type high-speed wire cutting device has the advantages that: the operation is simple, the adjustment for the straightening machine is simple and easy, and the cut-off size of the fed wire does not need to be adjusted; the product has high quality, has no quality defects such as short head free, double cutters, surface galling and the like, and has high yield; the detachment is quick and the maintenance is convenient, so the maintenance downtime is reduced; the automation degree is high, and the processes of removing oxide skins from wire rods, drawing steel wires and straightening and cutting off the steel wires are finished once, so the labor production efficiency is improved; and the working condition is improved, and the noise is reduced.

Description

(1) Technical field [0001] The invention relates to a metal wire cutting device, in particular to a flying shear type high-speed wire cutting device. (2) Background technology [0002] In the welding electrode manufacturing process, the shearing process of the welding core is an important factor affecting product quality and a key link in improving production efficiency. At present, in my country's welding rod production enterprises, the shearing process of the welding core usually adopts the principle of punching shearing and works in the form of an eccentric slider mechanism. The characteristic of this shearing process is that there is an idle stroke, which belongs to intermittent shearing, and the shearing frequency is low. The disadvantage of this shearing process is: low production capacity, and a single machine can only cut up to 180 welding cores per minute (with a value of ￠3.2 mm length is 350mm welding core as an example); the noise is large, and the noise is abov...

The characteristic of this shearing process is that there is an idle stroke, which belongs to intermittent shearing, and the shearing frequency is low. The disadvantage of this shearing process is: low production capacity, and a single machine can only cut 180 welding cores per minute (with a value of ￠3.2 mm length is 350mm welding core as an example); the noise is large, and the noise during operation is above 90 decibels, which is higher than the national standard (the noise level is required to be below 85 decibels); the operation is difficult, and an operator must master the cutting mechanism proficiently and achieve quality It requires at lea
