Problems solved by technology

Because the traditional manufacturing process has many processes, the thin and long process parts lead to springback, warping deformation, and dimensional inconsistency of semi-finished parts, which makes it difficult to accurately transfer the processing standards between processes, resulting in a low pass rate of parts and low production efficiency. very low

Abstract

The invention discloses a metal sheet punching and folding composite forming machine which comprises a base, an operation cavity is formed in the base, a vertical punching mechanism is arranged in the operation cavity, and the vertical punching mechanism is used for downwards punching a metal sheet; a slotting tool sliding block mechanism is arranged at the lower end of the vertical stamping mechanism, first-step vertical stamping forming of a metal sheet is achieved through the arranged vertical stamping mechanism, namely, through cooperation of a circular and rotatable cylindrical stamping block and a circular stamping rotating groove, and meanwhile through the arranged slotting tool sliding block mechanism and a slotting tool sliding block composite mechanism, the metal sheet can be subjected to second-step vertical stamping forming. The combined transmission between the vertical punching mechanism and the slotting tool sliding block mechanism is realized by utilizing the inclined surface and through the fitting of the profiling block, and the secondary punching in the horizontal direction is realized.

Description

technical field [0001] The invention relates to the technical field of metal bending, and more particularly relates to a metal thin plate punching and folding compound forming machine. Background technique [0002] Metal sheets are often used in the aesthetic process of some automotive machinery. They are required to be very smooth and smooth and have a high visual decorative effect. The raw materials used for parts are thin and narrow, and require dimensional deformation and very precise dimensions to ensure fit. Because the traditional manufacturing process has many processes, the thin and long process parts lead to springback, warping deformation, and dimensional inconsistency of semi-finished parts, which makes it difficult to accurately transfer the processing standards between processes, resulting in a low pass rate of parts and low production efficiency. very low. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present inven...
