2022 Best Metal Shear And Cheap Shearing Cutter For Sale

Metal shear is a machine that uses one blade to reciprocate linear motion relative to the other blade to shear plates. With the help of the moving upper blade and the fixed lower blade, a reasonable blade gap is used to apply shearing force to the metal plates of various thicknesses, so that the plates are broken and separated according to the required size. Shearing cutter is a kind of forging machinery, and its main function is in the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, ships, automobiles, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment.

1. Pedal Shearing Cutter： It means that the pedal spring adopts a sliding fulcrum fixed type, which reduces the operating force by two-thirds. Some machine tools are equipped with a material pressing device, which has a high cutting quality and has the characteristics of lightweight and convenient movement. It is widely used in the manual cutting of the metal sheet industry.

2. Mechanical Shearing Cutter: It is rotated by the motor, and the connecting rod is driven by the connected rack to rotate, and the eccentric wheel connected to the rotating shaft drives the tool holder to move up and down, so as to realize the cutting of the plate.

3. Electric Shearing Cutter: It is rotated by the motor, and the connecting rod is driven to rotate through the connected chain. The eccentric wheel connected to the rotating shaft drives the tool holder to move up and down, thereby realizing the shearing of the plate.

4. Swing Beam Shearing Cutter: The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the workbench. The tool post moves back and forth in an arc around the fixed axis to realize multiple linear shearing of the plate.

5. Guillotine Shearing Cutter: The oil cylinder is installed vertically on both sides of the machine, and the vertical movement of the oil cylinder drives the tool holder to move back and forth in the vertical direction, thereby realizing linear cutting of the metal sheet

1. The metal shear adopts a rectangular lower blade and can use four cutting edges for shearing, which can prolong the service life of the blade.

2. There is generally an auxiliary knife seat on the work surface of the shearing machine, which is used to make small adjustments to the blade.

3. The shearing cutter stroke can be adjusted, so it can not only achieve segmented shearing, but also improve the shearing efficiency, and automatically count the number of shears, thereby reducing the workload.

4. Use step-less adjustment to adjust the gap of the blade to adapt to the thickness of different plates and different shearing needs.

5. The shearing cutter is welded with steel plates and loaded with feeding balls on the work surface, so the operation and use are very convenient.

6. The hydraulic system of the hydraulic shearing cutter adopts an advanced integrated hydraulic system, which can not only reduce the installation of pipelines but also ensure safety and reliability during operation. The so-called killing of two birds with one stone.

The metal guillotine machine adopts the frame structure of all-steel welding; the four-corner and eight-sided right-angle guide rails have high precision and good rigidity and are hydraulically preloaded. The hydraulic system adopts a two-way cartridge integrated valve; the whole system adopts a stroke digital display, a photoelectric protection device and a mobile worktable (easy to replace the tooling). Function, the working pressure stroke can be adjusted according to the process requirements within the specified range, and the operation is easy to use centralized control of buttons.

Adjust the gap of the blade according to the thickness of the material to be sheared; adjust the template or fixture according to the width of the material to be sheared; make 1-3 empty strokes before the shearing cutter is operated, and then the shearing work can be carried out after it is normal. If it is found that the machine is not running normally during use, it should immediately cut off the power and stop it for inspection. When adjusting the machine tool, the power must be cut off, and when moving the workpiece, pay attention to the safety of hands. Each part of the shearing cutter should be kept lubricated frequently, the operator should add lubricating oil once in each shift, and the mechanic should add lubricating oil to the rolling bearing parts once every six months.

After shearing, the shearing cutter should be able to ensure the straightness and parallelism of the shearing surface of the sheared plate and minimize the distortion of the plate to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the worktable. A material support ball is installed on the worktable so that the sheet will not be scratched when sliding on it. The back gauge is used for sheet positioning, and the position is adjusted by the motor. The pressing cylinder is used to press the sheet to prevent the sheet from moving during shearing. Guardrails are safety devices to prevent workplace accidents. The return journey generally relies on nitrogen, which is fast and has a small impact.
