[CN201611106650.X] Hydraulic combined punching and shearing machine with good pressing effect
[CN201611106650.X] Title of a hydraulic combined punching and shearing machine with good pressing effect: Application number of a hydraulic combined punching and shearing machine with good pressing effect: CN201611106650.X Applicant: Anhui Zhongyi Machine Tool Manufacturing Co., Ltd. Application Date: 2016-12-6 Patent Type: Application of the Invention The present invention discloses a hydraulic combined punching and shearing machine with good pressing effect, belonging to the technical field of mechanical processing equipment. The invention includes a pressing mechanism, a follow-up pressing mechanism, a rear blocking mechanism, an oil cylinder fixing mechanism and a knife plate matching mechanism; wherein the follow-up pressing mechanism designs the pressing device on the punch and follows the punch Synchronous movement, during punching processing, the pressing device compresses the workpiece before the punch presses the workpiece to ensure the punching accuracy. After the punching is finished, the pressing device disengages the workpiece after the punch leaves the workpiece, it can effectively prevent the workpiece from jumping with the punch, and improve the service life and safety of the punching and shearing machine; the contact surface of the hydraulic cylinder and the body in the cylinder fixing mechanism is a pair of matching inclined wedge surfaces; the tool plate matching mechanism rotates the eccentric The shaft matches the moving knife plate with the static knife plate. The invention solves a variety of defects of the existing punching and shearing machine, improves the effect of the use of the punching and shearing machine, and the transformation cost of the existing punching and shearing machine is low and the economic benefit is good.
