Abstract

The present application relates to the field of mechanical processing, and particularly relates to a gear slot type damping pulley spinning tool, which is used in cooperation with a spinning machine and comprises an upper die mechanism, a lower die mechanism, a spinning wheel mechanism and a material withdrawing mechanism, and is used for manufacturing a gear slot type damping pulley. The gear slot type damping pulley is provided with a boss at the center and a lower edge on the circumference, and a gear slot is formed on the lower edge. The upper die mechanism is fixed on the upper base of the spinning machine. The lower die mechanism is fixed on the lower base of the spinning machine. The spinning wheel mechanism is connected to the radial cylinder of the equipment and is horizontally close to the upper die mechanism and the lower die mechanism during work. The material withdrawing mechanism is arranged in the upper die mechanism. The size of the upper die mechanism is larger than that of the lower die mechanism at the contact position of the upper die mechanism and the lower die mechanism. The present application also comprises a spinning processing method. The gear slot type damping pulley spinning tool and the manufacturing method can simplify the process, and the product processing efficiency is high, the processing precision is high, and the spinning process can be used to complete the processing of the gear slot type damping pulley with complex shape.
