Assembly welding tool generally used for hot blast main pipe elbows

Abstract

The invention provides an assembly welding tool generally used for hot blast main pipe elbows, aims to solve the problems in assembling and welding a hot blast main pipe elbow with different specifications, and comprises an assembling and welding platform base, a outlet flange positioning plate, an inlet flange center distance adjustment mechanism, an inlet flange height adjustment mechanism, an inlet flange angle adjustment mechanism, an inlet flange mounting hole center distance adjustment mechanism and a supporting frame adjusting mechanism, wherein the assembling and welding platform base is fixed on the horizontal plane, the outlet flange positioning plate and the supporting frame adjusting mechanism are mounted on the assembly welding platform base, the inlet flange center distance adjustment mechanism is mounted on one side of the assembling and welding platform base, and the inlet flange height adjustment mechanism and the inlet flange angle adjustment mechanism are fixed on the inlet flange center distance adjustment mechanism. The tool provided by the invention has the characteristics of compact structure and strong universality, guarantees the quality of products with different specifications, improves the working efficiency of welding and assembling, decreases the cost of rolled steel raw material, reduces the space occupied by equipment storage, and ensures the clean and civilized production environment of an enterprise.

Description

technical field [0001] The invention relates to a welding tool for metal parts, in particular to a universal welding tool for hot air main pipe elbow, which belongs to the field of welding technology. Background technique [0002] See attached Figure 1 to Figure 5 , the hot air main pipe elbow 1 is composed of an inlet flange 1-1, an elbow body 1-2, a connecting pipe 1-3, a set (two) of support frames 1-5 and an inlet flange 1-4. It is a metallurgical industry It is a part of the air supply system of ironmaking blast furnace. It includes two specifications of 90° hot blast main pipe elbow and hot blast main pipe elbow with variable α angle. Its overall dimensions and the angle α between the inlet and outlet flange installation surfaces It matches the size and structure of the ironmaking blast furnace. [0003] Usually, when the hot air main pipe elbow is assembled and welded, it is necessary to make a set of fixed tooling molds according to its external dimensions. Toolin...

AI Technical Summary

Problems solved by technology

After the assembly and welding of each hot air main pipe elbow is completed, these tooling molds have to be placed aside, which not only wastes steel raw materials, increases production costs, but also occupies a large storage space. At the same time, due to frequent replacement of tooling molds, it also affects improved production efficiency
