A kind of manufacturing method of flat electric welding rod and its manufacturing equipment

Abstract

The invention discloses a method and device for manufacturing flat welding electrodes. The method for manufacturing the flat welding electrodes comprises the following steps that a steel wire rod is rolled into a flat welding core wire rod at a time by means of a rolling device; the welding core wire rod is straightened and coated with a flux coating by means of a straightening and press-coating device, so that a continuous welding electrode provided with the flux coating is manufactured; the manufactured continuous welding electrode directly enters a welding electrode cutoff device to be cut into independent welding electrodes; and then the independent welding electrodes enter a head and tail grinding device through a welding electrode conveying device and are machined into the finished flat welding electrodes through the head and tail grinding device. The device for manufacturing the flat welding electrodes comprises, the rolling device, the straightening and press-coating device, the welding electrode cutoff device, the welding electrode conveying device and the head and tail grinding device, wherein the straightening and press-coating device, the welding electrode cutoff device, the welding electrode conveying device and the head and tail grinding device are arranged in sequence. The method and device for manufacturing the flat welding electrodes have the beneficial effects that the steel wire rod is machined into the flat welding core wire rod at a time, and the welding core wire rod is subjected to straightening, press-coating, fixed-length cutting and head and tail grinding in the manufacturing process, so that a continuous flow process is formed; fixed-length cutting is conducted after the flux coating is smeared; the machining technique is simple, and the production efficiency is high; the automation degree is high, and operation is easy and convenient.

Description

technical field [0001] The invention relates to a method for manufacturing an electrode and its manufacturing equipment, in particular to a method for manufacturing a flat electrode and its manufacturing equipment. Background technique [0002] As we all know, the existing welding rod products are mainly in the shape of round rods, and its manufacturing methods and manufacturing equipment are very mature, which also represents the prior art of welding rod manufacturing. Its general manufacturing method is: use the wire drawing machine to draw the steel disc circle into the welding core wire rod of the required diameter (the size of the welding rod specification) for many times, and use the straightening and cutting machine to draw the drawn welding core wire rod The welding core is processed into the required length (the length of the welding rod), and the welding rod coating is coated on the welding core by a pressure coating machine (screw or hydraulic pressure coating mac...

AI Technical Summary

Problems solved by technology

Although both the flat electrode and the round rod electrode belong to the coated electrode, due to the difference in the cross-sectional shape of the electrode, the production equipment using the round rod electrode is not suitable for manufacturing flat electrode products, especially in the There are essential differences in the links of drawing, straightening, cutting and coating of the welding core, so it is difficult to manufacture flat welding electrodes with the existing technology of manufacturing round rod welding electrodes and equipment of
