[CN 201821448063.3] plate shearing machine and lifting type rear material stop device thereof
[CN 201821448063.3] Title of a plate shearing machine and its lifting type rear material retaining device: Application number of a plate shearing machine and its lifting type rear material retaining device: CN 201821448063.3 Applicant: Anhui Hako Numerical Control Machine Tool Manufacturing Co., Ltd. Application date: 2018-9-5 Patent Type: Utility Model The utility model discloses a plate shearing machine and its lifting type rear material retaining device, belonging to the technical field of plate shearing machine material retaining. The plate shearing machine includes an upper tool holder and a rear material blocking device installed thereon; the rear material blocking device includes a material blocking beam, a material blocking driving mechanism and a material blocking lifting assembly; the material blocking driving mechanism is used to drive the material blocking beam to feed along the material blocking direction, which includes a shell and a sliding seat; the material blocking lifting assembly includes a hanger, a slope plate and a roller; the front end of the hanger is connected with the material blocking beam, the roller is installed at the rear end, and the middle part is rotatably connected to the sliding seat through the hanger shaft; the slope plate is installed at the end of the shell, and has a pressure wheel inclined surface facing the roller. The shearing machine of the utility model does not need to add additional drive control units and redundant parts, and does not sacrifice the function and accuracy of the original back-up material. Under the premise of making full use of the power of the original back-up material control system and the motor, the lever principle is used to achieve Lifting the blocking beam, so as to avoid the purpose of ultra-long sheet metal.
