AI Technical Summary

Problems solved by technology

At present, integral clamps are still used for transverse stretching and longitudinal stretching forming. When forming, the displacement of the end of the sheet is the same, it is not easy to mold, the transition zone is long, and the utilization rate of the material is low.
Due to the use of integral molds, the manufacturing cost is high in small batch production. When longitudinal stretching is formed, it is necessary to manually or use the control system to pre-adjust the positions of multiple clamps to drive the sheet metal to the mold. Although the transition area of ​​​​the material is reduced, the degree of mold adhesion is limited. improved, but the forming efficiency is very low
Despite continuous research and improvement of the stretch forming process, it is still difficult to solve the problems of uneven deformation of the sheet metal, difficulty in molding, wrinkling, and cracking. Therefore, a new type of metal forming die system and its metal forming are urgently needed. craft to solve real problems

Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples.

[0021] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention. The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Stretch forming is a stamping process that transfers the outer edge of the metal sheet blank to the side wall of the product, so that the sheet becomes an open hollow part or a deep hollow part due to multiple processes. When the stretching length of the hollow part exceeds its diameter value, it is called deep drawing, drawing and deep drawi...

Abstract

Disclosed is a metal forming die system and a metal forming process thereof, the metal forming die system includes a first stretch forming die, a second thin-wall forming die, a third bottom-pressing forming die and a fourth necking forming die, a metal original The second thin-wall forming die performs the thin-wall forming operation after several times of stretch forming by the first stretch forming die. After bottom pressing, the fourth necking forming mold is used for necking forming operation, so that the metal original is formed into a metal product, which solves the problems of uneven deformation of the sheet metal, difficulty in molding, wrinkling, and cracking, and improves the processing efficiency. Tall and well formed.

Description

technical field [0001] The invention relates to the field of metal processing, more specifically, to a metal forming die system and a metal forming process thereof. Background technique [0002] Mold is the main process equipment of industrial production, mold industry is a basic industry, and mold is also the key to product upgrading and benefit. At present, mold technology has become a very important manufacturing technology and one of the most active directions in the manufacturing field, with huge market potential and development space. [0003] The use of molds to produce parts has a series of advantages such as high production efficiency, good quality, low cost, energy saving and raw material saving. Therefore, it is widely used in the production of batch parts and components in the fields of household appliances, automobiles, construction, machinery, electronics, hardware, agriculture, and aerospace. It has become an important means of modern industrial production an...
