Edge cutting and bending one-time forming die for bracket of automobile fuel tank

Abstract

The invention discloses an edge cutting and bending one-time forming die for a bracket of an automobile fuel tank, and belongs to the field of automobile fuel tanks. The edge cutting and bending one-time forming die comprises a base, wherein the side faces of the top of the base are fixedly connected with supporting frames, the top of each supporting frame is fixedly sleeved with a hydraulic mechanism, the bottom ends of the hydraulic mechanisms are fixedly connected with an extrusion block, each supporting frame is movably sleeved with a moving sleeve, one side of each moving sleeve is fixedly connected with the side face of the extrusion block through a connecting plate, the bottom of each moving sleeve is in transmission connection with the top of the base through a movable spring, andthe top of the base is fixedly connected with a module. By arranging a port, a containing cavity, an electric push rod and an ejector block, the formed bracket can be automatically ejected out in theproduction and manufacturing process of the bracket of the automobile fuel tank, the bracket is separated from the module, the problem that because the bracket is tightly attached to the module, it isdifficult to take out the die is avoided, and thus convenience is brought to die taking of the formed die.

Description

technical field [0001] The invention belongs to the technical field of automobile fuel tanks, and in particular relates to a disposable molding die for trimming and bending an automobile fuel tank bracket. Background technique [0002] As the name implies, the automobile fuel tank refers to the tank used to hold gasoline on the automobile, and the automobile fuel tank can be divided into iron fuel tanks and aluminum alloy fuel tanks according to the manufacturing materials. During the installation and use of automobile fuel tanks, brackets will be used to support and fix them , because the automotive fuel tank bracket is generally bent, it is usually necessary to use a mold to squeeze and bend the metal plate during the production and processing of the bracket; however, most of the existing automotive fuel tank bracket molding dies are used During the process, since the metal plate is bent and deformed under the state of extrusion force, it is easy to make the metal plate ti...

[0002] As the name implies, the automobile fuel tank refers to the tank used to hold gasoline on the automobile, and the automobile fuel tank can be divided into iron fuel tanks and aluminum alloy fuel tanks according to the manufacturing materials. During the installation and use of automobile fuel tanks, brackets will be used to support and fix them , because the automotive fuel tank bracket is generally bent, it is usually necessary to use a mold to squeeze and bend the metal plate during the production and processing of the bracket; however, most of the existing automotive fuel tank bracket molding dies are used During the process, since the metal plate is bent and deformed under the state of extrusion force, it is easy to make the metal plate tightly adhere to the surface of the module and it is difficult to separate, so it is not convenient to remove the extruded bracket. For this purpose, we propose a one-time forming mold for trimming and bending of automobile fuel tank bracket
