Description

Technical Field

[0001] The utility model relates to the technical field of gantry shears, in particular to a gantry shear capable of automatically adjusting the height of a blade. Background Art

[0002] When the gantry shearing machine is working, the waste materials are pushed to the shearing platform by the pushing mechanism, and then the pressing head presses the materials on the shearing platform. Then the scissor seat moves downward, and the materials are cut by the shear blades set on the scissor seat and the shearing platform that shear against each other up and down.

[0003] The height of the shearing blade of traditional gantry shears is fixed and cannot be adjusted. When the sheared material is relatively thin, the upper knife and the press will run idle for a period of time, thus wasting time and energy. However, this design can detect the height of the press to automatically adjust the height of the blade, thus saving time and energy. Utility Model Content
