Introduction：Shear in industrial production is indispensable, shearing machine as a professional equipment with cutting function, can meet the different sizes, different thicknesses, different materials cutting needs.
What Is A Shearing Machine?
The shearing machine is a kind of equipment that uses the blade to do the up and down cutting movement, and the main cutting material is metal;
Shears can be cut according to size and shape you need;
Shears produces shearing force by the knife slide when cutting the material, and acts on the cutting material.
Working Principle
The shearing machine cuts the material by shearing force. Shear forces are generated by the interaction between the cutting edge and table. The cutting edge is on the top and the workbench is on the bottom. The material is between the two devices. The cutting edge is pressed down to press the material to the workbench. At the same time, a shearing force is generated to divide the material into the required shape and size.
Different Types Of The Shearing Machine
1. Hydraulic Shearing Machine
The hydraulic shearing machine drives the upper knife slide to press down through the hydraulic system, and the return cylinder is driven by nitrogen to make the upper knife slide return to the top. It is mainly used for processing large metal plates and is a metal shearing machine. According to different cutting methods, it can be divided into the following two types:
Swing-beam shearing machine with hydraulic upper transmission, its upper knife slide in the shear work around the fixed axis for the arc swing, through the role of the lever, the pivot point of the force is small, can improve the service life of the shear edge, and can be adjusted to the upper knife slide stroke, improve work efficiency;
The guillotine shearing machine has strong shearing force and excellent shearing effect, it is easy to cut thick plates, and the cutting straightness is better. It is a popular series in sheet metal processing.
Difference Between Swing-beam Shears And Guillotine Shears
Different movement
Guillotine shears knife slide is vertical up and down movement, relative to the lower blade for vertical straight line movement to ensure that the shear plate distortion deformation is small, straightness is more accurate; Swing-beam shears is a circular arc motion, and the knife slide is curved, ensuring the straightness of the cutting material by contacting the points of the arc.
Different use
Guillotine shears are mostly used for high-strength materials, thick plate cutting, Apply to automobile, machinery, ships, motor industry; Swing-beam shears is mostly used for thin metal cutting, apply to decoration, electrical, furniture industry.
Different shear angle
Swing-beam shear knife angle is fixed, shear speed can not be adjusted. The guillotine can realize the angle adjustment by adjusting the cylinder, when the shear angle increases, the shear thickness is increased, the shear angle decreases, the shear speed is accelerated, and the efficiency is improving.
Main Part Of Metal Shearing Machine
Control System
Optional controllers offer different functions to meet special requirements in metal working for optimal efficiency cutting.
Sheet Support System
The pneumatic supporting device is supported by the cylinders on both sides, and the lifting time is controlled by the electrical system, which can protect the sheet cutting and avoid the deformation of the sheet cutting.
BackGauge
The back gauge is equipped with a linear guide rail, which makes position positioning and repeated positioning more accurate and further improves the shear accuracy.Synchronous transmission construction is stable and reliable.
Worktable
Built-in spring press cylinder, where the lower part with special materials gas-kets, to avoid leaving trace line on materials surface. Using rolling steel ball, reduces friction, ensure the workpieces surface is not scratched.
2. Mechanical shearing Machine
Mechanical shearing machine is the earliest type of shearing machine, mainly composed of knife slide, shearing edge, worktable, transmission system and so on. Its working principle is to control the upper cutting edge downward pressure through the transmission system, the metal plate will be cut into the required shape. Mechanical shearing machine structure is simple, through the manual transmission, the price is relatively low, shear efficiency is low, suitable for small metal sheet processing.
3. Electric shearing machine
Electric shear is a kind of shearing machine that adopts electric motor to drive the upper cutting edge downward pressure, and its structure is similar to that of mechanical shear. Electric shears are simple to operate, relatively high shearing efficiency, suitable for small and medium-sized sheet metal processing.
4. Sheet metal cutters
It is a tool for cutting metal materials manually, with a wide variety of types, adapted to the simple cutting needs of people's daily life and production. And Can cut iron, paper, plastic, wood and other materials.
5. Bar shearing machine / 3 in 1 sheet metal machine
Hydraulic Ironworker is a small and multi-function machine, It can Punching, Shearing, notching, cutting and bending. The biggest advantage is shearing the profiles and bar, simple operation and high efficiency.
Development
In the past, hydraulic shearing machine as the main equipment in metal working industry, but with the development of intelligence, shearing machine needs to further improve the work efficiency and cutting quality, Therefore, CNC shears will become the main application, and has the following advantages.
1. More efficient, CNC shearing machine provides cutting programming and automatic cutting, greatly improving production efficiency;
2. The CNC shearing machine is controlled by the controller, and the accuracy is within 0.01mm;
3. CNC shearing machine is equipped with more safety devices to avoid dangers in the work;
4. Effective metal cutting can avoid material waste and save the machine's own consumption, achieving cost savings and environmental friendliness.
