Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, and more specifically, to an automobile stamping die with a positioning mechanism. Background Art

[0002] Automobile stamping dies are tools that use die plates (upper and lower dies) to punch, bend, stretch and other processing of metal sheets. During the stamping process, the relative movement of the upper and lower dies exerts a certain pressure on the metal sheet, causing the metal sheet to undergo plastic deformation and eventually form the required parts. Automobile stamping dies play a vital role in the automotive industry and are used to manufacture parts such as car bodies, doors, engine hoods, seats, steering wheels, etc.

[0003] In the prior art, although the method of stamping automobile parts by pressing down the upper die directly driven by the cylinder can realize basic stamping operations in many scenarios, this method has exposed some obvious limitations in practical applications. First, when the cylinder starts the upper die to approach the lower die for stamping, due to the limitations of mechanical motion inertia and control accuracy, the pressure generated by the upper die pressing down is sometimes difficult to control accurately, and it is easy to conflict with the lower die. This conflict may be manifested as the cooperation between the upper die and the lower die is not accurate enough, and even in some cases, it may cause damage to the mold. Secondly, due to improper pressure control during the stamping process, the stamping effect of automobile parts is often difficult to achieve the expected effect. Possible problems include inaccurate shape of parts, large dimensional deviation, poor surface quality, etc. These problems not only affect the appearance quality of the product, but more importantly, they may affect the performance and safety of the parts. In addition, poor stamping effect will also lead to material waste and increased rework rate. During the stamping process, if the shape or size of the part does not meet the requirements, it needs to be reworked or even scrapped, which not only increases production costs, but also reduces production efficiency. At the same time, material waste will also impose a certain burden on the environment. Utility Model Content
