Punch forming method of thin-wall end socket

Abstract

The invention provides a punch forming method of a thin-wall end socket. The method comprises the following steps of 1, cutting a non-ferrous metal plate to obtain an end socket plate, and cutting a steel plate to obtain an upper steel plate and a lower steel plate; 2, putting the end socket plate between the upper steel plate and the lower steel plate, and welding the upper steel plate and the lower steel plate into a whole plate along a circular arc; 3, heating the whole plate; 4, carrying out punch forming on the heated whole plate to obtain an entire end socket; and 5, removing the upper steel plate and the lower plate to obtain the thin-wall end socket of which the wall thickness is 0.5-3.0mm. The punch forming method is novel in technique, reliable and practical, and advanced in process. Two steel plates are adopted to clamp the end socket plate in the middle; the thin-wall end socket is punched and formed by a common die; the problems of large size, thin wall and large molding difficulty of lined end socket of chemical equipment can be effectively solved; the quality and the yield of the thin-wall end socket are improved; and the production cost is greatly reduced, and the economic benefit is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of head forming, and in particular relates to a stamping forming method of a thin-walled head. Background technique [0002] In chemical equipment such as internal pressure kettles with corrosive media, composite plates made of two metals through explosive welding are often used as their main materials. Composite panels use steel or steel forgings as the base layer, and use corrosion-resistant pure metal materials as the cladding layer. Especially when non-ferrous metal materials such as tantalum, titanium, zirconium, and nickel are used as corrosion-resistant materials, the cost is extremely high. In order to reduce the cost of composite panels, chemical equipment with loose lining structure is designed. [0003] At present, there are still many technical problems in the manufacturing process of chemical equipment with loose lining structure. Among them, in the chemical equipment with internal pressure and...

AI Technical Summary

Problems solved by technology

This method can effectively solve the problems of large size, thin wall thickness, and difficult forming of the lining head of chemical equipment, especially the thin-walled head with a wall thickness of 0.5 mm to 3 mm is more difficult to form; this method uses two steel plates to seal The head plate is sandwiched in the middle, and the thin-walled head is stamped and formed by ordinary head stamping and forming dies, which can effectively improve the quality and yield of the thin-walled head, and greatly reduce the production cost of the entire equipment in the chemical equipment manufacturing process , significantly improve the economic benefits of manufacturing enterprises
