One-way double-acting composite surface forming die and forming method thereof

Abstract

The invention provides a one-way double-acting composite surface forming die and a forming method thereof, and belongs to the technical field of sheet metal hot press forming. The problems that one or two kinds of parts cannot be formed through a single mold, and secondary formed parts cannot be obtained through one-time forming are solved. The die comprises a three-layer die structure and one-way double-acting mechanisms, the three-layer die structure comprises a male die, a middle die and a female die, the middle die is located between the male die and the female die, the male die and the middle die are connected through the two one-way double-acting mechanisms, and the two one-way double-acting mechanisms are symmetrically installed on the two sides of the male die and the two sides of the middle die. The upper end face of the middle mold is an upper molded surface, the lower end face of the middle mold is a lower molded surface, and the upper molded surface is different from the lower molded surface. The die is mainly used for forming a single set of die for secondary forming parts and producing two different parts.

Description

technical field [0001] The invention belongs to the technical field of hot press forming of sheet metal, and in particular relates to a one-way double-action composite profile forming die and a forming method thereof. Background technique [0002] As the production tasks are increasing day by day, small parts and twice-molded parts need to be manufactured with multiple sets of molds. The investment cost of small batch production is relatively large, which cannot achieve the original intention of saving costs and rejecting waste. The existing thermoforming The mold can only work with a single group of modules, and the device does not have the advantage of being able to form one or two parts with a single mold, and cannot solve the problem that the secondary molding parts can be obtained in one molding. Contents of the invention [0003] In view of this, the present invention aims to propose a one-way double-action compound surface forming mold and its forming method to solv...
