Description

Technical Field

[0001] This utility model belongs to the field of gantry shear technology, and in particular relates to a stepped cutting tool. Background Technology

[0002] The gantry shears consist of a moving blade holder that slides up and down to apply pressure and a stationary blade holder. The shearing action is achieved by the misalignment of the blades on the moving and stationary blade holders. However, the bottom surface of the moving blade holder is generally a planar structure or an inclined structure in the width direction of the gantry shears. This is too simple during shearing, and the hydraulic system is under heavy load, which affects the service life, as well as the shearing efficiency and effect. Summary of the Invention

[0003] The purpose of this utility model is to provide a stepped cutting tool. By designing a novel moving cutter holder, it presents a stepped structure after being assembled onto a gantry shear, realizing the partitioning of the cutting points. This reduces the load on the hydraulic system, increases service life, and the segmented shearing improves shearing efficiency and effect. It is also suitable for shearing complex materials and large batches of materials.

[0005] This utility model is a stepped cutting tool, including a fixed tool holder and a movable tool holder that is slidably disposed on a gantry frame;

[0006] The rear side of the moving tool holder is provided with several stepped sections, the cross-section of which is a right-angled triangle structure, and the height of the bottom surface of the moving tool holder increases from left to right.

[0007] The moving tool holder has sliding edges on both sides, and the gantry frame has slide rails on both sides. The two slide rails are staggered on the gantry frame. The moving tool holder slides up and down in the gantry frame through the sliding edges and slide rails. One side of the step is parallel to the width direction of the gantry frame. The moving tool holder forms a stepped tool holder on the gantry frame.

[0008] The bottom edge of each of the two sides of the stepped portion is provided with an upper insertion opening, and an upper blade body is fixed in the upper insertion opening;

[0009] The fixed tool holder has a stepped groove on its front side that mates with the moving tool holder. Several sides of the groove have a lower insertion opening at their top edges, and a lower tool body is fixed inside the lower insertion opening.

[0010] Furthermore, both the upper and lower cutting bodies are provided with mounting ports, and both the upper and lower embedding ports are provided with threaded openings, with fastening screws provided in the mounting ports and threaded openings.

[0011] Furthermore, both the upper and lower cutting bodies are provided with external pin holes, and both the upper and lower inserts are provided with internal pin holes, with a positioning pin between the external pin holes and the internal pin holes.

[0012] Furthermore, the sliding edge has a trapezoidal cross-section, and the outer surface of the sliding edge is perpendicular to the front surface of the moving tool holder.

[0013] Furthermore, the bottom end of the sliding edge extends beyond the bottom of the moving tool holder and forms an extension section, and the sliding edge is misaligned with the fixed tool holder.

[0014] This utility model has the following beneficial effects:

[0015] This invention features a novel moving blade holder that, when assembled onto a gantry shear, presents a stepped structure, enabling the partitioning of cutting points. This reduces the load on the hydraulic system, extends its service life, and improves cutting efficiency and effectiveness through segmented shearing.
