[CN 201610836153.9] A multifunctional punching and shearing machine with high shearing quality and convenient operation and its punching and shearing method Title: A multifunctional punching and shearing machine with high shearing quality and convenient operation and its punching and shearing method Application No.: CN 201610836153.9 Applicant: Anhui Zhongyi Machine Tool Manufacturing Co., Ltd. Application Date: 2016-9-20 Patent Type: Invention Application The invention discloses a multifunctional punching and shearing machine with high shearing quality and convenient operation and its punching and shearing method, the invention belongs to the technical field of mechanical processing equipment. The multifunctional punching and shearing machine of the present invention includes a knife plate matching mechanism. The knife plate matching mechanism includes a knife plate matching eccentric shaft. The knife plate matching eccentric shaft is sequentially provided with an outer fixed plate, a first concentric section, a second eccentric section and a third Concentric section, the knife plate matching eccentric shaft traverses the fuselage and is fixed with the wall plate of the fuselage through the outer fixed plate, and the knife plate is connected with the second eccentric section of the knife plate matching eccentric shaft through a connecting plate. The invention can make the moving knife plate rotate in an elliptical arc, and rotation in this way can ensure that the moving knife plate and the static knife plate can achieve position matching, and then the knife edges of the moving knife and the static knife can also achieve matching. This is a once-and-for-all method. After adjustment once, when the blade is replaced later, mismatch will not easily occur, which greatly facilitates the use of customers.
