Abstract
Description
Technical Field

[0002] The blades of a gantry shear consist of a moving blade holder and a fixed blade holder distributed vertically. The material is sheared by the staggered arrangement of the blades on the moving and fixed blade holders. Currently, the bottom surface of the upper blade holder (moving blade holder) is mostly a planar structure and the blades are parallel to the width direction of the moving blade holder. This requires a strong hydraulic load during shearing, resulting in high energy consumption and affecting the quality of the pump valve, thus affecting the shearing efficiency. At the same time, the overall downward pressure can cause uneven cutting force, affecting the cutting effect. Summary of the Invention
[0003] The purpose of this utility model is to provide an upper and lower blade holder for a gantry shear. By setting the rear side of the moving blade holder to a wave-like structure and dividing the blade body into multiple V-shaped distributions on the bottom edge of the outer protrusion, the force on the moving blade holder can be dispersed, realizing step-by-step shearing force application, improving the shearing effect and efficiency, while reducing the load on the hydraulic cylinder and increasing the service life of the hydraulic system.

The connection between the first inclined surface and the second inclined surface forms a height difference and is flush with the connection between the two outward protrusions.
[0008] The two side sections of the bottom edge of the protruding part are each provided with an upper insertion port, and an upper blade body is fixed in the upper insertion port;
[0009] The fixed tool holder has a notch on its front side. The notch is a wavy groove that mates with several protruding parts. Several inclined sections on the top edge of the notch are provided with lower insertion openings, and a lower tool body is fixed inside the lower insertion openings.
[0010] Furthermore, both sides of the moving tool holder are integrally provided with sliding positions, and the cross-section of the sliding positions is a regular trapezoidal structure.
