[CN 201910831290.7] Title of a cutting-edge plate shearing machine with NC adjustable shearing angle: Application number of a cutting-edge plate shearing machine with NC adjustable shearing angle: CN 201910831290.7 Applicant: National Machine Casting and Forging Machinery Co., Ltd. Application date: 2019-9-4 Patent type: Invention application The invention discloses a cutting-edge plate shearing machine with NC adjustable shearing angle, including bed assembly, upper cutter assembly, lower cutter assembly, hydraulic system, control system, guide assembly, the two ends of the bed of the bed assembly are respectively provided with "U"-shaped open grooves with upward openings. The upper knife seat of the upper knife assembly is placed in the "U"-shaped groove and is limited by the guide assembly; the guide assembly The limit roller reserves a gap for shear angle adjustment; the two ends of the upper knife seat extend out of the "U"-shaped groove; the hydraulic system includes an oil cylinder, a servo valve group, the oil cylinder of the hydraulic system is fixed at the outer position of the bed under the "U"-shaped groove through the mounting seat, and the cylinder rod of the oil cylinder is connected with the upper knife seat; the control system controls the synchronous action of the two oil cylinders through the servo valve group of the hydraulic system, or Respectively act the corresponding values within the set range. The invention realizes the automatic adjustment of the upper cutter shear angle digital display and numerical control, has a simple structure and light weight, and improves the processing efficiency of the production line.
