Problems solved by technology

Because the mechanical shearing machine adopts a rigid clutch, as long as the upper knife rest is given a downward signal, the upper knife rest must complete a cycle of shearing and return, and there is no overload protection device, which is very unsafe to use

Embodiment Construction

[0011] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail in conjunction with the accompanying drawings and preferred embodiments.

[0012] The gas-hydraulic pressurized pendulum shearing machine comprises a frame 1, an upper knife rest 2, a gas-liquid pressurized cylinder 3, an upper blade 4, a pressing cylinder 5, and a lower blade 6. The upper blade 4 is fixed on the upper knife rest 2, the lower blade 6 is fixed on the frame 1, and corresponds to the upper blade 4, and the pressing cylinder 5 is fixed on the frame 1, positioned above the lower blade 6, and the gas-liquid One end of the booster cylinder 3 is connected with the upper tool rest 2, and the other end of the gas-liquid booster cylinder 3 is connected with the frame 1.

[0013] The working process of the device is as follows: put in the workpiece to be cut, input the pneumatic signal, press th...

Abstract

The invention discloses a gas-liquid pressurization swing type plate shearing machine which comprises a rack, an upper tool rest, a gas-liquid pressurization cylinder, an upper blade, a material pressing air cylinder and a lower blade. The upper blade is fixed to the upper tool rest, the lower blade is fixed to the rack and corresponds to the upper blade, the material pressing air cylinder is fixed to the rack and is arranged above the lower blade, one end of the gas-liquid pressurization cylinder is connected with the upper tool rest, the other end of the gas-liquid pressurization cylinder is connected with the rack, and the gas-liquid pressurization cylinder pushes the tool rest to carry out swing type movement to complete a shearing motion. The gas-liquid pressurization cylinder is adopted as a power element, and compared with a mechanical plate shearing machine, the gas-liquid pressurization swing type plate shearing machine is low in noise, safe and reliable. Compared with a hydraulic swing type plate shearing machine, the gas-liquid pressurization swing type plate shearing machine is free of the trouble of hydraulic system temperature rise and oil pollution, and is an ideal machine for shearing a thin steel plate with a shearing width within the range of 1500mm.

Description

technical field [0001] The invention relates to a shearing machine, in particular to a gas-liquid pressurized pendulum shearing machine. Background technique [0002] At present, when cutting thin steel plates with a width less than 1500mm, most of the shears used for shearing are mechanical shears. Because the mechanical shearing machine uses a rigid clutch, as long as the upper knife rest is given a downward signal, the upper knife rest must complete a cycle of shearing and return, and there is no overload protection device, which is very unsafe to use. Contents of the invention [0003] In order to overcome the defects of the existing mechanical shears, the present invention designs a gas-hydraulic pressurized pendulum shears to further improve production efficiency, reduce noise, and improve safety and reliability in the process of shearing. [0004] The technical scheme adopted by the present invention to achieve the above object is: a gas-liquid pressurized pendulum...
