Stamping forming die for automobile front cross beam pipe

Abstract

The invention belongs to the technical field of stamping dies, and particularly relates to a stamping forming die for an automobile front cross beam pipe. The stamping forming die for the automobile front cross beam pipe comprises a die support, a hydraulic cylinder and adjusting knobs; a power box is fixedly connected to the upper surface of the die support; a hydraulic cylinder is fixedly connected to the position, inside the power box, of the upper surface of the die support; an upper die and a lower die are respectively arranged in the die support; and the front end surfaces of the upper die and the lower die are both rotationally connected with the uniformly arranged adjusting knobs. According to the stamping forming die for the automobile front cross beam pipe, a gasket type structure of the stamping die is effectively realized, so that the internal die change or the external die change work of a factory is greatly facilitated, the deformation adjustment can be carried out on thestructure, the problem of small product deformation can be solved technically, when the quality of a stamped part fluctuates, the adjustment can be carried out without die change, the die cost is reduced, and the production is convenient.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a stamping forming die for an automobile front beam tube. Background technique [0002] As the cross bar behind the car bumper, the front beam tube of the car plays the role of a supporting beam in the three-dimensional frame structure of the car. It is the second layer of protection for the engine after the bumper. When subjected to external impact, the car bumper can provide effective protection. When the impact force is large, the car insurance cylinder will be deformed or damaged. At this time, the car front beam tube is required for protection, which requires the car front beam to be able to effectively It has the function of energy absorption while supporting. In the design process, in order to improve the energy absorption capacity of the front beam tube of the car, the front beam tube of the car will be designed in a curved shape. After being impacted, it will pass ...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the existing technology, in order to make the accuracy of the automobile front beam tube meet the delivery requirements, pre-deformation design will be carried out, but the amount of pre-deformation is mostly judged according to the designer's work experience, and there is a large Deviation, during the stamping process of the front beam tube of the automobile, if the predicted deviation and the actual deviation are large, the mold needs to be modified, which greatly increases the mold manufacturing cost, and the change of the ambient temperature, the change of the design structure and the production process The adjustment and so on all have an uncertain influence on the amount of deformation, which has a great influence on the production of the forming die. The present invention proposes a stamping forming die for the front beam tube of the automobile.
