[0032] Working principle: During operation, lubricating oil is injected into the oil bag 110. After the oil bag 110 replenishes the lubricating oil for the fixed frame 105, the device is started and the gasket is sent to the fixed frame 105. When the gasket passes through the fixed frame 105, it will pass through the inside of the fixed frame 105. In the process of passing through the fixed frame 105, the gasket will come into contact with the first rotating wheel 109 and squeeze the first rotating wheel 109. After the first rotating wheel 109 is squeezed, the pressure will be transmitted to the connecting plate 108. After the connecting plate 108 is pressurized, the pressure will be transmitted to the spring 106 and the telescopic rod 107 to cause the two to contract. After the spring 106 contracts, the elastic potential energy will be released and a reaction force will be applied to the connecting plate 108, and then the connecting plate 108 will transmit the pressure to the first rotating wheel 109. The first rotating wheel 109 exerts force toward the gasket, and the first rotating wheel 109 starts to rotate in the friction with the gasket and is stained with the lubricating oil in the connecting plate 108. When the first rotating wheel 109 and the gasket have rolling friction, the lubricating oil on the surface of the first rotating wheel 109 will be brushed to the surface of the gasket, that is, the gasket will be brushed with lubricating oil when passing through the fixed frame 105, so as to realize the lubrication of the gasket by the device. Then, when the gasket reaches the bottom of the cross plate 103, the hydraulic cylinder 102 will start and drive the cross plate 103 to approach the gasket. When the cross plate 103 moves, it will drive the mold body 104 to approach the gasket until the mold body 104 contacts with the gasket and completes the punching work; before the gasket enters the fixed frame 105, it will first contact with the guide plate 2, and then the gasket will move along the The gasket slides along the surface of the guide plate 2. During the sliding process, the gasket will contact the second rotating wheel 22 and cause the second rotating wheel 22 to rotate. Under the rotation of the second rotating wheel 22, the gasket will slide along the guide plate 2 and pass through the fixed frame 105; when the gasket slides along the first rotating wheel 109, the first rotating wheel 109 will apply lubricating oil to the surface of the gasket. When the first rotating wheel 109 absorbs the lubricating oil inside the connecting plate 108, a small amount of lubricating oil will splash. The splashed lubricating oil will be intercepted by the baffle 3 and flow out along the gap between the baffle 3 and the first rotating wheel 109; when the gasket passes through the fixed frame 105, it will contact the bristles 42. When the bristles 42 contact the gasket, the lubricating oil on the surface of the gasket will be brushed again to remove some of the excess lubricating oil. The oil is distributed more evenly; when the gasket passes through the pick plate 4, the gasket will come into contact with the rubber pad 5. Because the friction coefficient of the rubber pad 5 is larger, the gasket and the rubber pad 5 will be subjected to greater friction when they come into contact, thereby reducing the transmission speed of the gasket and enhancing the fixing effect of the device on the gasket; when the device lubricates the gasket, excess lubricating oil will drip, and the dripping lubricating oil will drip onto the surface of the support seat 1 and then continue to flow along the fixing hole 6 until it falls into the inside of the fixing hole 6; when the lubricating oil drips into the collection box 62 through the fixing hole 6, the lubricating oil will drip to the bottom of the drawer 7.
