一般认为,在低碳钢板上冲裁比料厚小得多的孔是不可能的,因为冲头由于磨损太大而经常发生损坏。然而,分三次加工取代传统的一次性冲我是可以解决厚料的小孔冲裁问题的。 分步冲裁利用众所周知的事实,即:从金属板料上先冲剪分离出一块,此时,不必让冲头一下子冲透整个板厚,只要能有适当 It is generally believed that punching holes much smaller than the material thickness on mild steel is not possible because the punch often breaks down due to excessive wear. However, the three-time processing instead of the traditional one-time red I can solve the problem of punching holes thick material. Step-by-step blanking using the well-known fact that: from the sheet metal punching and cutting off a piece at this time, do not have to suddenly punch the entire thickness of the plate, as long as there can be appropriate
