Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and particularly relates to an automobile universal joint stamping die. Background Technique

[0002] An automobile universal joint stamping die is a die specifically designed for manufacturing automobile universal joints through the stamping process. The stamping process is a processing method in which an external force is applied to a blank through a die to cause plastic deformation or separation, thereby obtaining a workpiece with certain dimensions, shapes, and properties.

[0003] Before and after the production of the automobile universal joint, the stamping die needs to be cleaned to ensure the cleanliness of the forming cavity inside and prevent dust and impurities from affecting the production quality of the automobile universal joint. However, due to the deep depth and small space of the forming cavity of the lower die, it is difficult to clean the small gaps inside the forming cavity by the conventional method of using a brush. Therefore, an automobile universal joint stamping die is proposed. Content of the Utility Model
