A tool dedicated for build-up welding of magnetic medium

Abstract

The invention relates to a magnetic medium stack welding tool, which comprises frame, lower support block, upper support block and upper compressing block, wherein the middle of frame has chamber groove containing magnetic medium stack; the lower support block is sliding arranged at the bottom of frame; the lower compressing block is detachably arranged on two side bottom plates of frame; the upper support is at upper two sides of chamber groove; the upper compressing block is detachably arranged at two side top plates of frame. Therefore, the invention can stably clamp stainless steel plates to avoid deformation in welding process; and the medium rod is free in welding to be inserted into the holes of steel plate.

Description

technical field [0001] The invention relates to the field of metallurgical beneficiation, in particular to a special tool in the production of magnetic medium surfacing welding in a beneficiation machine. Background technique [0002] The magnetic medium in the mineral processing machine can be composed of thousands of metal rods densely embedded between two positioning thin plates according to certain rules. The size of the rods in the magnetic medium is Φ1~Φ4 (length: 60-550mm), such as Figure 1. Finally, the magnetic medium after welding must maintain a certain squareness (deformation ≤ 3 ~ 5mm). Thousands of rods are to be welded between two upper and lower thin steel plates (after the stainless steel rod passes through the stainless steel thin plate, the protruding length can be determined according to the welding process), and the strength of the welded joint after welding is close to the performance of the base metal; The welding methods are compared repeatedly, and ...

AI Technical Summary

Problems solved by technology

Thousands of rods are to be welded between two upper and lower thin steel plates (after the stainless steel rod passes through the stainless steel thin plate, the protruding length can be determined according to the welding process), and the strength of the welded joint after welding is close to the performance of the base metal; The welding methods are compared repeatedly, and the MIG semi-automatic welding process is ideal. During the welding process of multiple stainless steel sheets and thousands of round bars, due to their own small binding force, the stress is easy to release during welding, and the interval between each weld seam is very small. (1 ~ 10mm, which is the same as on a thin plate from beginning to end, continuously), resulting in large deformation; the previous method is to fix the unformed magnetic medium on a platform in a simple way, and then, first Welding the upper part, because the upper stainless steel sheet is not completely fixed, after the first few welds are welded, the deformation of the stainless steel sheet is quite obvious (1 ~ 5mm), causing some stainless steel rods to separate from the stainless steel sheet, and the welding process cannot be completed , even if the stainless steel rod and the stainless steel sheet are not separated, the final welding deformation is relatively large (generating overall distortion); first, the magnetic medium welding may fail, product quality cannot be guaranteed, and the production cost is high; second, it may be due to excessive deformation Roughly increases the amount of follow-up processing, which also increases the production cost;
