Problems solved by technology

The frontal impact load is mainly borne by the arc plate at the front end of the blade. In the prior art, the arc plate of the bulldozer blade is mainly made of high-strength steel plate HQ110 for welding structure, and the hardness is HB340-400. According to market feedback, there is insufficient hardness of the arc plate , severe wear and tear

Abstract

The invention relates to the technical field of bulldozers, and in particular to a welding process for a bulldozer blade. The bulldozer blade includes an arc-shaped plate, a crescent plate, a tool rest plate and a rear wall plate, wherein the arc-shaped plate and the crescent plate are both High-strength wear-resistant plate is used, and CO is used for welding 2 Gas shielded welding, first butt welding the crescent plate and the arc plate, then butt welding the tool holder plate and the arc plate, and finally welding the rear wall plate to the arc plate and the arc plate. The tool holder plate is butt welded. First, the arc plate and the crescent plate are made of high-strength wear-resistant plates, which significantly improves the wear resistance of the bulldozer; The optimal welding sequence between components, the mechanical properties of the blade after welding are excellent, and the impact performance is better.

Description

technical field [0001] The invention relates to the technical field of bulldozers, in particular to a welding process for bulldozer blades. Background technique [0002] In engineering construction, bulldozers mainly rely on the traction force of the whole machine to use the blade of the front working device to complete shoveling, soil transportation, filling, leveling and other operations. The frontal impact load is mainly borne by the arc plate at the front end of the blade. In the prior art, the arc plate of the bulldozer blade is mainly made of high-strength steel plate HQ110 for welding structure, and the hardness is HB340-400. According to market feedback, there is insufficient hardness of the arc plate , Severe wear and tear. [0003] NM400 is a kind of high-strength wear-resistant steel plate. NM- indicates the first letter of the Chinese pinyin of "resistant" and "grinding" for wear-resistant purposes, 400 is the Brinell hardness value HB value (400 hardness value...
