Plate Shearing Machine

A) Different working principles

The upper blade of the guillotine shearing machine is perpendicular to the lower blade, and the movement of the upper blade is controlled by the gate to achieve clamping and cutting. The upper blade of the swing beam shearing machine is in an inclined state, and the swinging mechanism tilts the upper blade to achieve the purpose of clamping and cutting.

B) Applicable scope varies

Hydraulic guillotine shear is suitable for thicker metal sheets cutting, while hydraulic swing beam shearing machine is only suitable for thinner metal sheets cutting.

C) Differences in accuracy and stability

Due to vertical clamping, the precision and stability of the guillotine plate shearing machine are higher than those of the swing beam shearing machine. The cut of the plate guillotine shearing machine is relatively flat and not easy to leave residue, making it suitable for fine cutting of small-sized boards.

D) Price difference

The price of hydraulic guillotine shearing machines is higher, while the price of hydraulic swing beam shearing machines is relatively lower.

1. Material scope

The plate shearing machine is generally suitable for cutting medium thick plates, and the thickness of the plates that can be cut is usually between 6mm and 60mm. Laser cutting machines are generally suitable for thinner plates but there are certain limitations for cutting thicker plates. Both plate shearing machines and laser cutting machines can cut common metal sheets. However, laser cutting machines cannot cut precious metals such as cobalt sheets and nickel sheets, and these material only use plate shearing machine to cut.

2. Cutting accuracy

The shearing machine, due to its mechanical cutting, does not generate stress and has higher cutting accuracy than laser cutting machines.

3. Cutting requirements

Cutting plates can generally only cut straight plate shapes, and the speed is fast. Laser cutting can process complex planar shapes, but graphics need to be drawn before processing.

4. Cutting cost

Cost is also an important factor affecting the selection of cutting equipment for different production needs. Laser cutting machines require efficient fiber lasers, cutting heads, and other equipment, so the price is generally higher, which is difficult for small and medium-sized enterprises to accept. The basic structure of the shearing machine is relatively simple and the cost is relatively low, making it more suitable for cost sensitive enterprises to choose shearing machines.

A) Specialized shearing machine

Cooperate with other devices to achieve special purposes:

1. Cold bending forming line shearing machine: specialized shearing machines configured on production lines such as automotive longitudinal beam cold bending line, carriage side panel production line, color steel plate forming line, etc.
2. Steel structure production line shearing machine: commonly used in automatic production lines for angle steel and H-shaped steel to complete the cutting process.
3. Plate opening and leveling line shearing machine: a high-speed shearing machine designed to meet the fast cutting requirements of the production line on the plate opening and leveling line. Hydraulic high-speed shearing machines are mostly used on thick plate lines, and pneumatic shearing machines are often equipped on thin plate lines; Equipped with flying shears on the high-speed line, continuous production with high efficiency.

B) Oblique blade shearing machine

The upper and lower blades of the shearing machine form an angle, and the upper blade is generally inclined, with a tilt angle of 1 °to 6 °. The shear force of the oblique blade shearing machine is smaller than that of the flat blade shearing machine, so the motor power and overall weight are greatly reduced. Hydraulic guillotine shear is one type of oblique blade shearing machine. It is most commonly used in practical applications, and shearing machine manufacturers often produce this type of shearing machine.

C) Flat blade shearing machine

Good shear quality, small twisting deformation, but high shear force and high energy consumption. There are many mechanical transmissions. The upper and lower blades of the shearing machine are parallel to each other and are commonly used in hot cutting of billets and slabs in steel mills; According to its cutting method, it can be divided into upper cutting and lower cutting.

D) Multipurpose shearing machine

1. hydraulic ironworker: can complete the cutting of sheet metal and also cut profiles, commonly used in cutting processes.
2. Plate bending and shearing machine: It can complete two processes of cutting and bending on the same machine.
