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


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;



Guillotine Shearing Machine


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.

5 Factors to Consider before buying a Metal Shearing ...

Are you planning to buy a shearing machine? Are you aware of all the things you need to consider before the machine? As an organization with years of expertise in the field, we have prepared for you a list of things to think about before you buy a metal shearing machine.


Purchasing a machine to shear and shape sheet metal can be a significant investment for your company, but because these equipment are costly, it's critical to weigh your options. 

The sort of machine you require depends on your needs, as most are evaluated based on their ability to cut through various metal thicknesses, material quality, and appropriateness. Consider these factors before buying a shearing machine:


1. Metal:

Sheet metal comes in a variety of forms and sizes, but the thickness, kind, and consistency are more essential than the length and width. 

Sheet metal may always be broken down into smaller pieces. A larger metal shearing machine is desirable, but not necessary, if you want to lower the overall time it takes to cut sheet metal.

If you're shearing thin gauge metals or light aluminium, an air or electrically operated shear may suffice, but if you 're shearing ¾ plate with plasma cut slots, a superior mechanical shear may be required for impact absorption.

Tread Plate, Expanded Metals, Perforated Metals, and other materials that shear differently than flat material of equal make are all crucial to consider.


2. Quantity of sheared parts:

The number of components you need to shear is almost as crucial as the material you're working with. While a basic and inexpensive machine would serve low-volume, intermittent use, a more advanced or sturdy machine would be necessary for steel service centre manufacturing.


Not only do the machines come in a variety of styles, but they may also be customised with a variety of features, such as conveyor/stackers that transport the sheared metal to a stack on a pallet for rapid removal. High-speed hydraulics or more precise front gauging are two other alternatives.


3. Design:

The Guillotine style and the Swing Beam style are the two major design kinds of shears on the market. In a shear, a guillotine design refers to the upper blade being driven directly downward by the driving system, while a swing beam pivots the upper blade and uses momentum to force it down.

Because of the advantage of leverage it employs in the design, the Guillotine style provides a more robust, but more costly shearing mechanism, whilst the Swing Beam type uses fewer drive components.


4. Rake Angle:

The upper blade's angle is referred to as the rake angle. A lower angle produces a better shearing edge and necessitates more force to shear. The optimal rake angle is zero degrees, however that would be too costly for the shear machine. Adjustable rakes employ smaller shears and lengthen the production process, whereas fixed rake angles stay in place throughout shearing.


5. Shearing system:

There are five different shearing systems to choose from. Each of these systems has its own set of advantages and disadvantages, and some might not even function with your selected material at all.


Mechanical: 

Lasts the longest, produces the most, and absorbs the most. Mechanical shears are quiet, quick, and easy to operate. They'll withstand a lot of wear and tear, and they'll probably last a long time.


Hydraulic: 

Hydraulic presses or shears use a shearing blade and thick hydraulics with 14 gauge shears. They are less expensive than mechanical shears, but they do not cut as quickly.


Electric: 

Electricity, inertia, and force are used to drive the shears with electric equipment. Smooth, quick, and quiet, they can work down 12-14 gauge steels.


Air-operated:

Air-operated shears combine manual shears with a pneumatic element to alleviate operator fatigue. They are typically used on 18 gauge or thinner gauges.


Manual: 

Manual shears, the earliest type of shearing equipment, work with 18 gauge or thinner metal and are a light machine utilised in most HVAC industries.
