About Shearing
In today’s fast-paced and highly competitive manufacturing industry, efficiency is crucial for keeping profitability and outpacing competitors. Among the various tools and technologies that enhance operational performance, shearing machines stand out for their ability to cut sheet metal and other materials with exceptional speed and precision. By automating and streamlining cutting processes, these machines have revolutionized how many manufacturers run. Below, we explore how shearing machines boost efficiency within a manufacturing plant, offering real-world examples and insights from industry experts. Shearing machines—often called metal shears or sheet metal shears—play a vital role in many production environments. Operators use them to cut through sheet metal and other materials quickly and accurately, removing unwanted material to create precise, finished components. Compared to manual cutting processes, shearing machines significantly enhance workflow, minimize errors, and reduce waste. This improvement in cutting efficiency raises production ability and helps manufacturers keep consistent quality across product lines. Moreover, modern shearing machines often come equipped with digital controls and automated features, which allow seamless integration into computer-aided manufacturing (CAM) systems. By centralizing data input and process monitoring, manufacturers can reduce setup times, perfect tool paths, and further enhance precision.
Types of Shearing Machines
Various shearing machines are available, each suited for specific materials, production volumes, and levels of precision. Below are the three main types:
1. Mechanical Shears
Mechanical shears employ a motor-driven flywheel to generate cutting force. They run at high speeds and are ideal for high-volume production runs where time is of the essence. Their straightforward design makes them relatively easy to keep and integrate into existing workflows.
2. Hydraulic Shears
Hydraulic shears use hydraulic power to drive the blade, delivering strong cutting force and excellent precision. They excel at handling thicker or tougher materials like stainless steel, carbon steel, and high-grade alloys. Their adjustable cutting parameters allow for refined control, resulting in cleaner edges and minimal material distortion.
3. Pneumatic Shears
Pneumatic shears use compressed air to power the cutting blade. While they are less common than mechanical or hydraulic shears, they can be extremely useful in niche applications that require moderate force but demand quick and frequent cutting cycles. Pneumatic shears are also easier to keep in environments where hydraulic systems might pose a risk of fluid leaks.
Principle
The gate shearing machine relies on the hydraulic system to work. Its oil cylinder is installed on both sides of the engine, which drives the knife holder to move back and forth vertically to achieve straight cutting. The upper and lower blades have four cutting edges, the knife gap [2] can be adjusted, the cutting angle [1] can be adjusted electrically, the knife holder is returned by the nitrogen cylinder (or hydraulic return), when cutting thick metal plates, can achieve better performance.
Introduction
The blade material of a shearing machine usually includes T10, 9CrSI, 6CrW2Si, Cr12MoV, H13, alloy steel, and other materials. These blades are widely used in various industries such as light industry, aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, and steel structure construction and decoration. A shearing machine works with a moving upper blade and a fixed lower blade. By using the right blade gap, it applies shearing force to metal sheets of different thicknesses, making them break and separate into the desired size. Shearing machines are a type of forging machinery, used in the metal processing industry. Generally, shearing machines can be divided into pedal type (manual), mechanical type, hydraulic swing type, and hydraulic brake type. They are often used to cut blanks with straight edges. The shearing process should meet the straightness and parallelism requirements of the cut sheet’s surface and minimize distortion to get a high-quality workpiece.
Instructions
Start the shearing machine and let it idle for a few cycles to make sure everything is normal. Then, do some evaluate cuts with different thicknesses, starting from thin to thick. This way, you can get familiar with the blade performance of the hydraulic guillotine shearing machine. Remember to adjust the blade gap according to the plate thickness during trial cutting. If you do not, it will affect the blade’s durability. Turn on the pressure gauge switch while cutting and keep an eye on the oil pressure value. When cutting a 12mm plate, the pressure should be less than 20MPa. The remote pressure regulating valve No9 is set to 20 – 22MPa at the factory, and you must follow this rule. Do not increase the pressure to cut materials beyond the specified surface, or you might damage the machine. Listen for a balanced sound during operation. If there’s noise from the blades of the hydraulic guillotine shearing machine, stop and check it out. When the hydraulic guillotine shear blade is working, make sure the maximum temperature of the oil tank is less than 60 degrees. If it exceeds that, shut down the machine and let it rest.
Safe operating
Before you start operating, put on tight-fitting protective clothing and fasten your cuffs. Do not leave your jacket hem open. Also, do not wear, take off, or wrap your clothes around the machine to avoid getting twisted. Always wear a safety helmet, and if you have braids, tuck them into the hat. No skirts or slippers allowed. The operator of this machine tool must be well-versed in the main structure, performance, and usage of the hydraulic guillotine shear blade. This machine tool is designed to cut various steel plates, copper plates, aluminum plates, and non-metallic material plates with the rated thickness of the machine. The materials should be free of hard marks, welding slag, slag inclusions, and welds. Also, do not use materials that are too thick. If you notice any abnormal operation during use, immediately cut off the power and shut down the machine for inspection. When adjusting the machine tool, always cut off the power supply. And when moving the workpiece, be careful of your hands. Keep all parts of the machine tool lubricated regularly. The operator should fill the lubricating oil once per shift, and the mechanic should lubricate the rolling bearing part every six months.
Application
Small and medium-sized CNC shearing machine blades are used in hydraulic guillotine shearing machines, hydraulic pendulum shearing machines, mechanical shearing machines, pedal shearing machines, and other forging machine tools. They are commonly used in sheet metal processing, light industry, electrical appliances, metallurgy, instrumentation, shipbuilding, aviation, stainless steel products, steel structure construction, and decoration industries. You can find them widely used in major fields like the metallurgical industry, packaging industry, paper industry, printing industry, carton industry, garden wood industry, rubber and plastic industry, food industry, electronic materials, shipbuilding, construction and repair, automobile manufacturing, and mechanical equipment.
