Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, in particular to a hydraulic gantry gate type special shearing machine for plastic plates. Background Art

[0002] Hydraulic shearing machine is a machine that uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates can be broken and separated according to the required size. Shearing machine is a kind of shearing equipment that is widely used in machining. It can shear steel plates of various thicknesses. In the process of processing plastic plates, in order to meet human needs and transportation needs, they need to be cut into blocks of the same shape and size, so shearing machines are needed.

The frame is fixedly installed on the top left of the workbench, and the two sets of hydraulic cylinders are fixedly installed on the workbench. The output ends of the two sets of hydraulic cylinders are respectively fixedly connected to the front and rear of the top of the shearing knife. The workbench is provided with a cutting knife slit corresponding to the shearing knife, and the gantry is fixedly installed on the top right of the workbench. It can effectively limit the plate to avoid the occurrence of warping during the plate cutting operation, reduce the occurrence of injury, and is safer and more reliable.

[0004] However, in the implementation of relevant technologies, it was found that the hydraulic gate shearing machine designed above for the production and processing of butterfly valves has the following problems: in the above technical solution, the plate is fed from the right to the left of the workbench to the bottom of the shearing knife, and the two groups of hydraulic cylinders are started. The output ends of the two groups of hydraulic cylinders are extended synchronously, and the shearing knife moves downward to cut the plate. However, when shearing, the shearing knife cannot be positioned and guided, which causes the shearing knife to easily deviate when shearing the workpiece, thereby reducing the processing quality. In view of this, a hydraulic gantry gate shearing machine specifically for plastic plates is provided to overcome the above-mentioned defects. Utility Model Content
