A hydraulic shearing machine is a type of shearing machines, which is used to cut the metal sheets that can be made of various kinds of alloys such as bronze, aluminum, brass and mild steel.
Similar to the principle that we use scissors to cut a piece of sheet, the sheet is placed between the two blades, and the blades being compressed to cut the piece of sheet off.
However, the pressure the hydraulic shearing machine provides is much larger than the normal scissors, as it is specialized in larger, thicker, and heavier workpieces, in order to make the workpieces be machined to their applications.
There are two main types of shearing machines that are applied for the cutting work of metal sheets, including the hydraulic shearing machine and the mechanical shearing machine.
The hydraulic shearing machine, which is what we discuss here, is driven by the hydraulic system that it is equipped with. The hydraulic system contains a hydraulic oil pump, which would pump out the hydraulic oil and give pressure to the shearing blades, so as to perform the shearing work on the workpieces.
The manufacturers of the metal sheets may prefer hydraulic shearing machine more, since the energy consumption of the hydraulic shearing machine is less that makes this machine cost-effective.
In addition, the hydraulic shearing machine performs well in shearing the workpieces fast without making loud noise, as the pressure that is given to the workpieces is from the hydraulic oil, which results in the reduced working time and increased product output.
A hydraulic shearing machine is mainly formed by three systems, including the electric system, hydraulic system, and the back gauge system, and these systems and some basic components are covered by the frame of the hydraulic shearing machine.
No matter what type of shearing machines there is, the two most vital roles in the machine are the shearing blades and the workpieces. The workpieces are put on the left and right boards, which are set upon a large rectangular worktable.
There are two shear blades on the hydraulic sharing machine, one is the upper blade and the other is the lower blade. The upper blade is held by the blade carrier, and would move up and down to perform the shearing works. The lower blade is fixed on the blade holder, which interacts with the upper blade to make the cuts.
The hydraulic shearing machines can be divided into two types based on the movement methods of the blade carriers, including the hydraulic swing beam shearing machine and the hydraulic guillotine shearing machine.
The hydraulic swing bean shearing machine, also called the hydraulic pivot blade shearing machine, which the upper blade carrier of the machine is swung around the pivot. While the blade of the hydraulic guillotine shearing machine is not swung. Instead, it is stationary and the blade on it can be adjusted to different angles.
There are several differences between the hydraulic swing beam shearing machine and the hydraulic guillotine shearing machine, including the shear angle, the shear movement, and the shear edges of the blade.
