The utility model relates to the technical field of machining, and discloses a plate bearing device of a bending machine, which comprises a bending machine main body, the outer wall of the bending machine main body is provided with a mounting base, the outer wall of the mounting base is fixedly provided with a motor I, the outer wall of the mounting base is provided with a sliding chute I, and the sliding chute I is provided with a sliding chute II. The outer edge of an output shaft of the first motor is fixedly sleeved with a first double-end lead screw, the outer wall of the first double-end lead screw is in threaded connection with a sliding block, a machine body is fixedly installed on the outer wall of the sliding block, and universal wheels are arranged at the bottom of the machine body. According to the bending machine, the sleeve slides, the connecting rod is driven to push the turning plate to turn over, then the turning plate is turned over to 45-90 degrees to be continuously adjusted, meanwhile, the air cylinder is matched to drive the containing plate to slide, automatic switching from V-shaped bending to U-shaped bending is completed, and then the auxiliary efficiency of the bending machine in the plate bending process is effectively improved.

This utility model relates to the technical field of bending machines that facilitate positioning, and more particularly to a bending machine that facilitates positioning, comprising a fixed base plate, support legs fixedly mounted on both sides of the top of the fixed base plate, a receiving seat plate fixedly mounted on the top of the support legs, a mounting hinge seat fixedly mounted on the top of the middle section of the fixed base plate, a hinge cylinder hinged to the top of the mounting hinge seat, a sliding plate fixedly connected to the top output end of the hinge cylinder, and a mounting slide rail fixedly mounted on the top of the sliding plate. Through a multi-component collaborative positioning design, processing accuracy is significantly improved; the cylinder four on the receiving seat plate drives the limiting push block to restrict the material position from the front and rear directions; the cylinder five on the fixed base plate drives the stop block to achieve longitudinal limiting, and the telescopic rod provides buffering stability; this all-round positioning method effectively avoids material displacement during processing, making the bending angle and position more accurate, reducing scrap rate, and ensuring product quality.
