Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, in particular to a shearing machine cutting device. Background Art

[0002] The shearing machine is a machine that uses one blade to make reciprocating linear motion relative to another blade to shear the plate. It uses the moving upper blade and the fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates can be broken and separated according to the required size. The shearing machine is a kind of forging machinery. Its main function is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electricity, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment. After shearing, the plate machine should be able to ensure the straightness and parallelism requirements 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 tool holder, and the lower blade is fixed on the workbench. A support ball is installed on the workbench so that the plate is not scratched when sliding on it. The back stop is used to position the plate, and the position is adjusted by the motor. The pressure cylinder is used to press the plate to prevent the plate from moving during shearing. The guardrail is a safety device to prevent industrial accidents. The return stroke generally relies on nitrogen, with fast speed and small impact.

[0003] According to a shearing mechanism for a shearing machine with a patent number of CN218875733U published on the China Patent Network, it includes a shearing machine housing, an upper cutting knife, a lower cutting knife and an automatic discharging structure. The right side of the shearing machine housing is provided with a discharging platform through a hinge, and the automatic discharging structure is bolted to the bottom of the discharging platform and the right side of the shearing machine housing respectively; the automatic discharging structure includes a fixed block, a fixed plate is bolted to the front of the fixed block, the left side of the fixed plate is bolted to the shearing machine housing, a positioning block is integrally formed on the left side of the top of the fixed block, and the discharging plate is hinged on the top of the positioning block. The shearing mechanism of the shearing machine has an automatic discharging structure installed at the bottom of the discharging table on the right side of the shearing machine. After the lower cutting knife cuts the wooden board and places it on the top of the discharging table, the automatic discharging structure can cooperate to make the wood fall a short distance to the upper part of the electric conveyor belt for automatic discharging. This not only reduces noise but also protects the cut wooden board and improves the practicality of the shearing machine. However, the shearing machine does not have a protective component. When shearing metal plates, some small pieces of metal may splash due to the shearing force. The splashed metal may cause harm to the user and there is a safety hazard.

[0004] Therefore, it is necessary to redesign the shearing machine to effectively prevent the phenomenon that it is difficult to protect. Utility Model Content
