Problems solved by technology

Existing solutions to this problem generally adopt the process of opening air vents or increasing the gap between the punch and the blank holder to prevent the upper die from carrying material. This process has an effect on preventing the upper die of the steel plate mold from carrying material , but it has little effect on preventing the upper mold from carrying material on the aluminum plate mold

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0024] Such as Figure 1 to Figure 5 As shown, the mechanism for preventing the upper die of the drawing die of the aluminum plate is the aluminum plate clamping mechanism located at the four corners of the blank holder of the drawing die. When the upper die returns, the aluminum plate is clamped and positioned by the movable chuck, effectively Preventing the return of the upper mold with material ensures the smooth progress of the automatic production process of aluminum plate parts and also ensures the automatic production cycle.

[0025] The aluminum plate clamping mechanism includes a fixed seat 2, a driving cylinder 3 and a movable chuck 1 for clamping the aluminum plate. The fixed seat 2 is fixed on the drawing die by bolts, and the driving force of the driving cylinder 3 is provided by a...

Abstract

The invention discloses a mechanism for preventing an upper die of a drawing die of an aluminum plate from being stripped. A cylinder and a movable collet for clamping the aluminum plate, the movable collet is hinged on the installation fixed seat, one end of the driving cylinder is hinged on the installation fixed seat, the other end of the driving cylinder is hinged with one end of the movable collet, and the movable collet is hinged on the installation fixed seat. The other end of the collet is the clamping end of the aluminum plate. The structure of the mechanism is reasonable in total. When the upper die returns, the aluminum plate is clamped and positioned by the movable chuck, which can effectively prevent the upper die from carrying materials during the return journey, which ensures the smooth progress of the automatic production process of the aluminum plate, and also ensures the automatic production rhythm. The structure is simple and convenient. Production, low cost.

Description

technical field [0001] The invention relates to the technical field of drawing dies, in particular to a mechanism for preventing the upper die of the drawing die of an aluminum sheet from carrying material. Background technique [0002] Facing the new energy crisis and environmental pollution problems, aluminum alloy lightweight materials have become a hot issue in the research of automotive materials. In the development process of lightweight automobiles, aluminum alloy materials also encounter competition and challenges from light materials such as magnesium, plastics, and ceramics; It is more and more widely used in the process of automobile lightweight. [0003] Since the density of aluminum is light, only one-third of the density of steel plate, there is a problem of carrying material on the upper mold during the production process. Existing solutions to this problem generally adopt the process of opening air vents or increasing the gap between the punch and the blank...
