Description

Technical Field

[0001] The present invention relates to the technical field of plate processing, in particular to a small pneumatic continuous plate shearing and blanking machine. Background Art

[0002] A shearing machine, also known as a shearing machine, uses a blade that moves back and forth linearly relative to another to shear metal sheets. Using a moving upper blade and a fixed lower blade, with a reasonable gap between the blades, the machine applies shear force to metal sheets of various thicknesses, breaking and separating the sheets to the desired size. Shearing machines are a type of forging machine, primarily used in the metalworking industry.

[0003] Pneumatic shears use compressed air as their power source to shear. Traditional shears are often manually controlled, and the cut sheets are also manually handled. In recent years, with the rapid development of mechanical automation, continuous shears have emerged that can continuously cut to a set size.

[0004] The principle is also very simple. An automatic feeding device is integrated on the basis of the original shearing machine to continuously cut the thinner rolled plates. The system of the automatic feeding device is coupled with the shearing machine control system to cooperate with each other to achieve the purpose of continuous cutting.

[0005] At present, continuous shearing machines are widely used because they do not require manual operation. However, the unloading mechanism of this type of shearing machine still needs to use additional power to control unloading. At the same time, the upper and lower blades of the continuous shearing machine are prone to overheating due to continuous operation. Most companies also use active energy cooling methods.
