Description

Technical Field

[0001] The utility model relates to the technical field of presses, in particular to a press for processing unqualified products. Background Art

[0002] A press is a versatile, compact machine with a high production efficiency. It is widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. It applies strong pressure to metal blanks, causing them to plastically deform and fracture, thus forming parts. In operation, a mechanical press is driven by an electric motor via a V-belt, driving a large pulley. This, in turn, drives a crankshaft mechanism through a gear pair and clutch, causing the slider and punch to descend in a straight line. After the forging process is completed, the slider moves upward, the clutch automatically disengages, and the automatic actuator on the crankshaft engages, causing the slider to stop near top dead center.

[0003] During the production process of automotive mufflers, some substandard, defective products may be produced. To prevent these defective products from entering the market, a press is required to crush them. However, due to the lack of protective equipment during the crushing process, the broken mufflers can easily fly into the environment, posing a significant hazard to workers. Therefore, to address this issue, we have developed a press for handling substandard products. Utility Model Content
