Thick plate welding defect removal machine

Abstract

The invention relates to thick plate welding equipment, particularly to a thick plate welding defect removal machine applied to the welding process of medium-thick steel plates, thick steel plates and large-scale thick-wall pipelines. The thick plate welding defect removal machine comprises a traveling mechanism and a removal mechanism, wherein the traveling mechanism is a traveling trolley traveling along a straight welding seam or pipeline annular welding seam; the removal mechanism comprises a thin grinding wheel rotating driven by a motor; the removal mechanism is integrally assembled on a removal mechanism supporting seat fixed with the traveling mechanism by a pushing rotary shaft and a pretightening force spring through a mounting base plate; the removal mechanism is provided with a pushing handle capable of integrally pushing the removal mechanism to enable the thin grinding wheel to push the welding seam size. According to the thick plate welding defect removal machine disclosed by the invention, the structure is simple, the cost is low, convenience in manufacture is facilitated, consumptive parts can be replaced at any time, the welding defect in the welding seam can be effectively removed, few influence on the welding seam tissue during the removal process is generated, and change on the welding bead tissue is not caused.

Description

technical field [0001] The invention relates to thick plate welding equipment, in particular to a thick plate welding defect cleaning machine used in the welding process of medium-thickness and large-thickness steel plates and large thick-walled pipelines. Background technique [0002] In the field of heavy equipment manufacturing, such as forging presses, shipbuilding, mining and large steel structures, more and more medium-thickness and large-thickness rolled steel plates are used to make parts. In order to ensure the mechanical properties of these parts, it is necessary to ensure The manufactured parts must not have any welding defects inside the weld. However, welding defects such as pores, slag inclusions, lack of fusion, cracks, etc. will inevitably appear during the production process, especially when these parts are produced manually. For large-thickness steel plates, the common cleaning method is generally Carbon arc gouging cleans welding defects, and when this me...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that when a defect occurs in the welding process of the above-mentioned thick plate, because the defect position is narrow and deep, it cannot be repaired by ordinary cleaning methods, and provides a simple structure, low cost, easy to manufacture, and can be replaced at any time It can effectively clean up the welding defects in the weld seam, and the cleaning process will basically not affect the structure of the weld seam, and will not cause changes in the structure of the weld meat.
