Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to an automobile crossbeam stamping die with easy positioning. Background Technique

[0002] Common stamping dies for automobile rear top crossbeam parts on the market are generally formed by combining an upper die and a lower die. An oil cylinder drives the upper die to descend, and the sheet metal located on the lower die is stamped to draw and form the sheet metal. The automobile rear top crossbeam parts need to be installed on the vehicle frame. Therefore, the edge position of the automobile rear top crossbeam needs to be bent at a large angle to form an edge for installation. After the sheet metal is bent at a large angle, draw springback will occur, and the springback amount of the sheet metal bending needs to be restricted to a certain extent. Among them, a stamping die for an automobile rear top crossbeam part with the application number "CN202323097277.4", the utility model reduces the draw springback amount of the sheet metal after bending by setting an electric heating plate for heating inside the pressure strip, heating the pressure strip through the electric heating plate, the pressure strip is located at the position where the sheet metal needs to be bent at a large angle, and the heated pressure strip heats the position where the sheet metal is bent at a large angle. After the bent part is heated, the stress generated inside the material due to bending is reduced, thereby reducing the draw springback amount after the sheet metal is bent and improving the quality of the finished product after the sheet metal is stamped, which has strong practicability. However, there are still certain deficiencies in the use of this stamping die: since the die does not have a positioning structure, the workpiece to be stamped is directly placed on the lower die for stamping, which easily causes the raw material to shift, resulting in deviation in the stamping position. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automobile crossbeam stamping die with easy positioning to solve the problem that due to the lack of a positioning structure in the die, the workpiece to be stamped is directly placed on the lower die for stamping, which easily causes the raw material to shift, resulting in deviation in the stamping position as proposed in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an automobile crossbeam stamping die with easy positioning, including a stamping component and a positioning component;

[0005] Among them: the stamping component includes a pedestal, the middle part of the surface of the pedestal is provided with a lower die, the periphery of the surface of the pedestal is provided with electric hydraulic cylinders, the top of the electric hydraulic cylinders is provided with a mounting plate, and the bottom of the mounting plate is provided with an upper die;
