The method of punching the plastic parts of the automobile plastic parts is generally to punch the plastic parts on the table, the left hand is placed on the table top, the drill bit is clamped in the hand piece of the drill bit, the bit drive motor is started, and the hand grip device is held in the right hand to Vertically perpendicular to the angle of the product punching surface, the punch of the high-speed rotating device is forced to the product. After the drill bit passes through the product intentionally, the drill bit is pulled out and the above action is repeated until the hole number requirement of the product is completed. When there is a need for punching on different sides of a product, it is necessary to manually flip the product so that the punching surface is horizontally upward so that the drill bit can be punched down.


The method is prone to the phenomenon that the chips, the drill bit breaks and is stuck in the product, causing serious quality defects to the product, which may cause parts to be reworked, resulting in production stoppages and waiting for a long working time; the punching position is arbitrarily large and cannot be fixed. It will cause serious hidden dangers to the subsequent use of the product, which will lead to product rework and scrapping; at the same time, the personnel operation is extremely easy to fatigue, which increases the labor intensity of the workers.
