High-efficiency gantry shearing machine

Abstract

The invention discloses a high-efficiency gantry shearing machine. The high-efficiency gantry shearing machine comprises a gantry frame, a cutting cutter, a workbench and a conveyor belt, wherein theportal frame comprises two stand columns which are arranged along the vertical direction and a cross beam which is fixed at the tops of the stand columns; a main hydraulic cylinder is arranged on thecross beam, and a piston rod of the main hydraulic cylinder is fixedly connected with a connecting base; the cutting cutter is connected to the connecting base through a bolt, the workbench is locatedbelow the cutting cutter, and the conveyor belt is located on the side part of the workbench and is connected with the workbench; and a first hydraulic cylinder and a second hydraulic cylinder are fixedly arranged on the side of the conveyor belt, a supporting shaft is connected to a piston rod of the first hydraulic cylinder and the piston rod of the second hydraulic cylinder, a turntable is installed in the middle of the supporting shaft, a pressing roller is fixed on the surface of the turntable, and a protection sleeve made of an anti-slip material is arranged outside the pressing rollerin a sleeved mode. The high-efficiency gantry shearing machine has the advantages that a tool is easy to grind, and good in fixing effect, and the working efficiency of the gantry shearing machine canbe greatly improved.

Description

technical field [0001] The invention relates to the field of shearing equipment, in particular to a high-efficiency gantry shearing machine, which has the characteristics of easy grinding of knives and good fixing effect, and is especially suitable for shearing irregular and long-length objects. Background technique [0002] Gantry shearing machine is a kind of shearing machine, which is suitable for cold shearing of various shapes of steel and various scrap metal components, and is often used in the metal recycling industry. However, the gantry shears on the market now often press and fix the sheared end of the material during use. When shearing, the uncut end is prone to move, and the fixation of the material is not very good, and it cannot According to the different sizes of the material, it can be properly squeezed and fixed, and at the same time, the cut material cannot be collected well, which cannot meet the needs of actual work. [0003] As the cutting time increase...

AI Technical Summary

Problems solved by technology

[0004] The traditional process of grinding and replacing the cutter is cumbersome, which greatly affects the working efficiency of the gantry shearing machine. Therefore, there is an urgent need for technology that can improve the structure of the gantry shearing machine to perfect this equipment.
