U shaped suspension clamp swaging technique

Abstract

The invention discloses a mould forging process used on a U-shaped hanging folder as a component of a hanging boiler in the manufacturing process of a power station boiler. A forging die and a trimming die are manufactured, the cavity outline of the forging die is fundamentally identical to the outline of the U-shaped hanging folder, and the forging die has a forging margin and a draft; firstly, material are forged into blank which is then arranged in the mould cavity for forging molding, at last the raw edges are removed by the trimming die; the sub-forging die of the mould forging is positioned at the central line of the U-shaped hanging folder, with an outer draft of 7 DEG and an inner draft of 5 DEG; the bridge part of the forging die is provided with a choke trough; the blank presents a dumbbell shape. The mould forging process provided by the invention has the advantages that the die, the blank structure and the technics steps are reasonable and practical; the U-shaped hanging folder forge piece is forged and molded at one go, the lifting lug dispenses with bending, the quality of products is acceptable, the production efficiency is high, the minimum output per shift is more than 200, and the economic benefit is good.

Description

technical field [0001] The invention relates to a U-shaped hanging clip, which is mainly used for hanging boiler parts in the manufacturing process of a power station boiler, and specifically relates to a forging process of the U-shaped hanging clip. Background technique [0002] U-shaped hanging clamp is a hanging tool used in the manufacturing process of power station boilers. It is used to hang the boiler parts for assembly and welding. U-shaped hanging clips are used in a large amount and have many specifications, but their basic structure is the same, but the size is different. Its structure is shown in Figure 1 (ie Picture 1-1 , Figure 1-2 ) shows: a hanging chuck 1, two lifting lugs, the lifting lug has an earring 3 and an ear handle 2, and the two lifting lugs are vertically and symmetrically arranged on the top of the hanging chuck 1, forming a clip shape. The traditional U-shaped lifting clamp is a steel casting, the metallographic structure is limited in densit...

AI Technical Summary

Problems solved by technology

The problem is: because the bending angle is too large, exceeding 90°, when bending, there will be serious creases on the inner side of the bottom corner of the fork, and severe strain on the outer side. The strength does not meet the requirements, and no qualified products have been produced so far.
