Description

Technical Field

[0001] This utility model relates to the field of stamping machine technology, specifically a stamping machine with an ejector structure. Background Technology

[0002] Automotive brackets are devices used to support and fix automotive parts and components. In the production process of automotive brackets, they are usually manufactured using stamping machines. However, existing stamping machines still have certain defects in use, such as...

[0003] After stamping, the workpiece is easily stuck in the lower die or outside the upper die of the existing stamping press, requiring manual removal. Most of them do not have an ejector structure. In addition, the existing stamping press usually exposes the die directly to the outside. During the stamping process, external objects can easily enter the stamping die and affect the processing. At the same time, the workpiece is prone to splashing out when it is misaligned, lacking a protective structure. Utility Model Content
