[CN 201620598004.9] Cam Mechanism for Pending Out of Male Die of Six Die Six-punch Rivet Cold Heading Machine
[CN 201620598004.9] Title of male die ejection cam mechanism of a six-die six-punch rivet cold heading machine: Application number of male die ejection cam mechanism of a six-die six-punch rivet cold heading machine: CN 201620598004.9 Applicant: Application date of Jiangsu Aived Fastener Co., Ltd.: 2016-6-17 Patent Type: Utility Model The utility model discloses a male die ejection cam mechanism of a six-die six-punch rivet cold heading machine, belonging to the field of rivet forming equipment. The utility model includes a body, a linkage mechanism, a cam mounting seat, a cam plate, a roller and a swing arm. The cam mounting seat is installed on the body through a cam shaft, the cam plate is installed at the bottom of the cam mounting seat, the linkage mechanism and the cam The upper part of the mounting seat is connected, the swing arm is installed on the body through the swing arm shaft, the roller is installed at one end of the swing arm, and the roller matches the cam profile of the cam, the other end of the swing arm is opposed to the male die ejection punch; the starting section of the cam profile of the cam plate is composed of a gentle curve, and the ejection section is composed of a convex curve. The utility model designs the starting section of the cam plate to be more gentle, while the ejection section is steeper and more prominent, so that the initial stage of the ejection action is longer, the possibility of product deformation is reduced, and the ejection stroke of the ejection stage is longer, the ejection action is more accurate and stable, and the synchronization is better.
