Abstract
The utility model discloses a sticking prevention mechanism of a punching die. The sticking prevention mechanism comprises a positioning sleeve, a punching stick and a discharging device. The positioning sleeve is internally provided with a three-level stepped hole. The three-level stepped hole forms a first sliding cavity, a second sliding cavity and a third sliding cavity, wherein the first sliding cavity, the second sliding cavity and the third sliding cavity are sequentially communicated. The discharging device is arranged in the third sliding cavity. A limiting plate is arranged at the tail end of the discharging device and arranged in the second sliding cavity. The punching stick is arranged inside the discharging device. The tail end of the punching stick is arranged in the first sliding cavity through a connecting plate. An ejector pin matched with the discharging device is arranged between the connecting plate and the limiting plate. A reset component used for resetting the discharging device is arranged between the discharging device and the positioning sleeve. According to the sticking prevention mechanism, after a hole is punched through the punching stick, the ejector pin pushes the discharging device to move upwards until the punching stick is completely sleeved with the discharging device, workpieces which may be stuck to the punching stick are pushed down, operation safety in the punching process is ensured, and the product quality is improved.
