Process for forming pipe end sleeves

Abstract

The invention belongs to the field of forming processes of complicated metal plate parts, and relates to a process for forming pipe end sleeves. By adoption of the forming method, the problems that three tiny paws are not attached to a mould and roots of the tiny paws are prone to cracking are solved, the edge-bending forming difficulty of the parts is greatly lowered, the labor amount of operators is decreased, the production efficiency is improved, the rejection rate of the parts is lowered to 1%-5%, and the production cost is reduced. According to the novel technical scheme, a great progress is made both in the aspect of the economic benefits and in the aspect of quality.

Description

technical field [0001] The invention belongs to the category of forming technology of sheet metal complex parts, and relates to a forming technology method of pipe end sleeve parts. Background technique [0002] In the research and production process of a certain type of machine, the shape of the parts is as follows: Figure 1 , The material of this kind of pipe end sleeve parts is LF21M aluminum plate of GBn168-82, the thickness of the material is 0.6mm, the size of the part is 250mm×250mm, the height of the three small claws of the part is 35mm, and each small claw has The wavy bending and small claws add great difficulty to the operator's forming work, which is prone to non-stick tires and insufficient corrugation depth. Manual forming cannot ensure that the parts fully meet the requirements of the drawing, and the parts will Figure II The three small claws of the Figure 1 Defects such as cracks are prone to appear during the shape process.
