Description

一种饰条自动的冲切喷油装置  Automatic cutting and injection device for decorative strips
技术领域Technical field

背景技术Background technique
汽车外水切亮条半成品通过滚压工艺生产，在以汽车外水切成品装配的汽车之前，需要通过冲床冲切出缺口并进行端部翻边，现有作业流程是作业员从外水切半成品台车内取出半成品，手持***模具，在冲床压力下，模具冲切出产品缺口形状，再进行端部翻边，由于冲切翻边工艺模块受力大，表面要求高，导致模具翻边块易磨损，为降低摩擦，采用手动喷油进行润滑以提高模具寿命，降低模具故障率。但同时手动喷油会导致工时损失，节拍降低，也有较大安全风险，喷油量的随机性也会影响冲切品质，如喷油量过大，会导致产品表面脏污，如喷油量过小，会无法起到充分润滑作用。作业员在进行冲切作业时，靠人手工冲切喷油操作有安全风险。The automobile outer water cut bright semi-finished product is produced by the rolling process. Before the car is assembled with the outer water of the automobile, the punching machine needs to punch out the notch and carry out the end flanging. The existing operation process is that the operator cuts the semi-finished product from the outer water. The semi-finished product is taken out in the trolley, and the mold is inserted into the mold. Under the pressure of the punching machine, the die is punched out to cut out the shape of the product, and then the end is turned over. The punching and flanging process module is subjected to high force and high surface requirement, resulting in the mold flanging block. Easy to wear, in order to reduce friction, manual injection lubrication is used to improve mold life and reduce mold failure rate. However, at the same time, manual fuel injection will lead to loss of working hours, lowering of the beat, and greater safety risks. The randomness of the fuel injection quantity will also affect the punching quality. If the fuel injection amount is too large, the surface of the product will be dirty, such as the fuel injection amount. Too small, it will not fully lubricate. When the operator performs the punching operation, there is a safety risk by manually punching the fuel injection operation.
