A device for efficiently removing the weld reinforcement of composite stainless steel pipes

Abstract

The invention discloses a device for efficiently removing welding seam surplus height of a composite stainless steel tube. The device comprises a base, wherein a grinding device and a conveying deviceare sequentially arranged in the horizontal direction at the upper end of the base; the conveying device comprises a hydraulic oil cylinder which is fixedly connected to the upper end of the base; atelescopic end of the hydraulic oil cylinder is fixedly connected with a conveying table; the grinding device comprises a supporting plate which is fixedly connected to the upper end of the base; a drive motor is arranged on the side wall of the supporting plate; the output shaft of the drive motor is fixedly connected with a grinding barrel; a plurality of wedge-shaped slots are formed in the inner wall of the grinding barrel at equal distance; grinding knives are inserted into the wedge-shaped slots; and a plurality of limiting slots are formed in the side walls of the grinding knives. The device is reasonable in structural design, is simple to operate, is high in working efficiency, is good in cut-off quality, is low in cost, finally improves tube-manufacturing working efficiency, and ensures tube manufacturing quality.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to a device for efficiently removing weld reinforcement of composite stainless steel pipes. Background technique [0002] Composite stainless steel structural steel pipe is a newly developed steel pipe variety. It not only has the mechanical properties of carbon steel pipe, but also has the characteristics of anti-corrosion, acid resistance and decoration of stainless steel. It is a high-efficiency and energy-saving product. Due to the particularity of the composite stainless steel material (that is, the stainless steel layer is compounded on the ordinary carbon steel base), the joint cannot be welded by high-frequency welding, and only a special welding method can be selected for welding, so as to form a relatively tight joint at the joint. The weld seam is wide (about 10mm) and has excess height (about 2mm). Due to the low welding speed and stainless steel material, it ca...

Problems solved by technology

Due to the particularity of the composite stainless steel material (that is, the stainless steel layer is compounded on the ordinary carbon steel base), the joint part cannot be welded by high-frequency welding, and only a special welding method can be selected for welding, so as to form a relatively tight joint at the joint. Wide (about 10mm) and excess height (about 2mm) weld seam, due to the low welding speed and stainless steel material, it cannot be removed by conventional scraping

The structure of the existing excess height removal device is complicated, the cutter head is not easy to replace, and the high temperature in the grinding process makes the cutter head wear more seriously, reducing the service life of the cutter head
