[CN 201611266951.9] A Plate Shearing Machine Rear Blocking Device and Its Use Method Title: A Plate Shearing Machine Rear Blocking Device and Its Use Method Application Number: CN 201611266951.9 Applicant: Maanshan Jinlong Machine Tool Factory Application Date: 2016-12-31 Patent Type: Invention Application The present invention discloses a plate shearing machine rear blocking device and its use method, belonging to the technical field of plate shearing processing and production. The invention includes a guide post, a sliding block, a ball screw and a ball nut. The guide post is a hollow tubular structure, and the axial tube wall is provided with a sliding groove; after the ball nut and the ball screw are slidably sleeved, the two ends of the guide post are tightly matched. The bearing is fixed inside the guide post; the slider has a hollow block structure, and after being sleeved on the guide post, it extends into the sliding groove through the connecting mechanism and the ball nut is detachably and the ball nut. The invention combines the traditional two-split structure of the guide post and the sliding block, the ball screw and the ball nut into an integrated structure, which greatly reduces the working space of the rear stop device, and the guide post can be used for the ball screw and The ball nut is protected in all directions, avoid the dust, debris and other impurities caused by the complex operating environment of the shearing machine falling into the ball screw and ball nut and affecting the shearing machining accuracy and the service life of the ball screw and ball nut.
