Description

Technical Field

[0001] The utility model relates to the field of automobile moulds, in particular to a high-depth drawing mould for an inner plate of a left side plate. Background Art

[0002] Automotive drawing dies are commonly used in the production of automotive parts, especially in the forming process of metal sheets. Drawing is a metal forming process that stretches or flattens metal sheets to produce plastic deformation in a specific direction to produce parts of the desired shape. Drawing dies are tools used to achieve this forming process.

[0003] The left inner panel of the car body, also known as the left front beam inner panel or the left body inner panel, is usually located on the left side of the car body and together with other parts of the car body (such as the frame, outer panels, etc.) constitutes the overall structure of the car body. It is a large metal sheet that needs to be formed into the metal sheet according to the design requirements through a drawing die to meet its structural and functional requirements.

[0004] Since the inner plate of the left plate is a large grooved plate, the contact area with the core of the drawing mold is large when it is placed on the core, and the friction between them is large. Therefore, the plate position cannot be placed in place at one time and there is a deviation in the core position. Every time the plate is placed for stamping, the production staff needs to confirm the position, which is prone to negligence and inaccurate position confirmation, resulting in the scrapping of the plate drawing, and will delay production efficiency. This needs to be improved. Utility Model Content
