Introduce the working principle of hydraulic shearing machine
2021-04-22
Hydraulic shearing machineThe upper roller is acted on by the hydraulic oil in the hydraulic cylinder at the symmetrical position of the two lower rollers, and the two lower roller gears are driven by the last gear of the main reducer to cooperate with the rotational movement to provide torque for the rolling plate. The hydraulic bending machine includes a bracket, a worktable and a clamping plate. The worktable is placed on the bracket. The worktable is composed of a base and a pressing plate. The base is connected with the clamping plate through a hinge. The base is composed of a seat shell, a coil and a cover plate. The coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by the wire, and the pressure plate is energized to generate attractive force, so as to realize the clamping of the thin plate between the pressure plate and the base.
Due to the use of electromagnetic force clamping, so that the pressure plate can be made into a variety of workpiece requirements, but also the side wall of the workpiece processing. The hydraulic press shall remove the lower bearing plate, shutter and positioning core, place the 0.10/1000 square level meter on the piston end face vertically and horizontally, and find the vertical and horizontal direction to ± 1 grid. If it exceeds ± 1 grid, add shim iron on the bottom surface of the lower nut to find it again, tighten the anchor nut, and review it until it is qualified.
The hydraulic press is mainly a frame, hydraulic system, cooling system, pressurized oil cylinder, upper mold and lower mold. The pressurized oil cylinder is installed at the upper end of the frame and connected with the upper mold. The cooling system is connected with the upper mold and the lower mold. It is characterized in that the lower end of the frame is equipped with a mobile workbench and a mobile oil cylinder connected with the mobile workbench, and the lower mold is placed on the mobile workbench. ByHydraulic shearing machineThe three working rolls (two lower rolls and one upper roll), the hydraulic shearing machine specifications flat plastic metal plate, with the help of the upper roll down and the rotation of the lower roll, the metal plate is continuously bent through multiple channels, causing permanent plastic deformation, and rolling to the required cylinder, the cone or its part .. The disadvantage of the hydraulic three-roll hydraulic shearing machine is that the plate end needs to be pre-bent by other equipment .. The hydraulic shearing machine is suitable for large hydraulic shearing machines with a thickness greater than 50mm .. Add a row of fixed rollers at the lower part of the two lower rollers to shorten the span of the two lower rollers, thereby improving the accuracy of the rolled workpiece and the overall performance of the machine.
