In the shearing machine, we have learned about the gate shearing machine and the Best shearing machine, which have many performance characteristics and are widely used. Let our technicians tell you about shearing machines.
Characteristics of gate shears:
1. It adopts all-steel welded structure, with good rigidity and stability. At the same time, it adopts advanced integrated hydraulic system with good reliability.
2. The existence of the three-point bearing rolling guide can eliminate the bearing clearance and effectively improve the shear quality.
3. The blade gap can be adjusted by hand wheel, which is fast, accurate and convenient. All four edges of the rectangular insert can be used for a long service life.
4. The shearing angle of the gate shearing machine can be adjusted to effectively reduce the deformation of the metal plate. The upper tool rest adopts an inwardly inclined structure, which is convenient for unloading and improves the accuracy of the workpiece.
5. It has a dimming function machine, which can block the material after moving, and has a digital display.
6. Working table and stripping device, the use of support rods and support balls can make the plate move more freely.
The difference between gate shears and pendulum shears
1. Different uses
(1) Application of gate shearing machine: It can be used in related industries such as automobiles, ships, motors, instruments and meters. In addition, it is also suitable for stretching operations of various high-strength alloy plates.
(2) Application of pendulum shearing machine: used for stretching, bending and extrusion forming of metal plates in electric power, aviation and other industries.
2. Different features
（1）Characteristics of gate shears
a. It adopts an integral welded frame structure and undergoes vibration aging treatment. The machine tool has good rigidity, high precision and good retention.
b. There are three supporting shaft rolling guides, the upper tool rest rolls in the rolling guides without gap, and the service life of the blades can be adjusted by turning the handwheel.
c. The uniformity of the gap between the movable knife holder and the four-edged long blade improves the cutting quality and prolongs the service life of the blade.
d. The series oil cylinder synchronization system makes the machine tool evenly stressed, and the shear angle can be easily adjusted by adjusting the flow rate of the series oil cylinder to meet the needs of different shear plate thicknesses.
e. The existence of electric back gauge device and electronic technology can effectively and conveniently adjust the position of back gauge.
（2）Characteristics of pendulum shears
a. Compared with ordinary types, bevel shears are mostly used, which are widely used because of their simple structure, low failure rate, high shearing efficiency, and no bending, warping, and twisting of metal plates.
b. During the cutting process, the cutting clearance angle and cutting clearance will change as the tool holder rotates.
3. Different structure
(1) Gate type shearing machine structure: It adopts frame structure, all steel welding, four-corner and eight-side right-angle guide rails, high precision, good rigidity, and hydraulic preloading.
(2) Structure of pendulum shearing machine: After shearing, the flatness and parallelism of the shearing surface of the sheared plate can be ensured, and the deformation of the plate can be minimized, so as to obtain high-quality workpieces .
