A side baffle for submerged arc welding of shaft parts

Abstract

The invention relates to a side baffle for submerged arc welding of shaft parts, which comprises a side baffle body, a layer of asbestos is attached to the front surface of the side baffle body, and several magnetic columns are evenly fixed on the lower side of the front end surface of the side baffle body. An end block is respectively fixed on the left and right sides of the lower end surface of the side baffle body, a compression spring is respectively fixed on the inner side of the end block, and a holding plate is respectively fixed on the other end of the compression spring. The holding boards are all installed on the lower end surface of the side baffle body through a sliding connection, and the inner surfaces of the holding boards are all concave arc surfaces. In the present invention, the holding plate is used to be stuck on the surface of the shaft part, specifically, it can be stuck at the annular groove of the shaft part, so that the side baffle body is blocked on the side of the working surface of the shaft part, and the fixing of the side baffle body is improved. Stability, combined with the adsorption effect of the magnetic column on the shaft parts, further ensures the fixing reliability of the side baffle body.

Description

technical field [0001] The invention relates to the technical field of protective equipment for processing shaft parts, in particular to a side baffle for submerged arc welding of shaft parts. Background technique [0002] Shaft parts wear excessively after long-term use, and the cost of replacing parts is high. Usually, submerged arc welding is used to weld a layer of metal welding layer on the side of the shaft parts, and then the metal welding layer is turned to make the shaft parts re-" restore life". [0003] During submerged arc welding of shaft parts, the molten metal welding fluid often flows into the annular groove of the shaft parts along the radial direction of the shaft parts, forming welding slag, which is not conducive to subsequent turning. In the prior art, a metal plate is pre-welded on the side of the processing surface to prevent the molten metal from overflowing. However, the metal plate is often adhered to the welding liquid, and it is difficult to remo...

[0003] During submerged arc welding of shaft parts, the molten metal welding fluid often flows into the annular groove of the shaft parts along the radial direction of the shaft parts, forming welding slag, which is not conducive to subsequent turning

In the prior art, a metal plate is pre-welded on the side of the processing surface to prevent the molten metal from overflowing. However, it is often difficult to remove the used metal plate after the metal plate is adhered to the welding liquid.
