A Metal Shear is an industrial machinery with rotating disks and blades to cut metal bars and hard iron sheets. Shearing refers to applying high pressure on a metal bar once to remove a portion of the metal. The cutting mechanism of all metal shears uses the same arrangement of a fixed upper blade, a lower blade, and an adjustable clearance between the two. When pressure is applied to the upper blade, the lower blade is compelled to cut and split the metal in two.
Benefits of Metal Shear
Precision Cutting
Metal Shears are integral to the steel rolling mill industry due to their unparalleled precision in cutting steel products. In an industry where the quality of the final product is essential, the ability to make clean, precise cuts is indispensable. These machines excel in providing accurate cuts, ensuring that the steel products meet the required specifications.
Enhancing Productivity
Efficiency is the linchpin of any steel rolling mill. Metal Shears significantly enhance productivity by cutting steel at predetermined lengths swiftly and accurately. This saves time and reduces material wastage, making your operations more cost-effective.
Safety and Operator Convenience
Metal Shears come equipped with safety features that protect operators from potential hazards. These features often include safety covers, emergency stop buttons, and other safety mechanisms. Moreover, modern machines boast user-friendly interfaces, making them easier for operators to control and monitor, further enhancing safety. The semiotics design of our machinery intuitively induce safety.
Reducing Downtime
Regular maintenance of Metal Shears can prevent unexpected breakdowns and downtime, ensuring that your rolling mill operates seamlessly. By following the right maintenance procedures, you can extend the lifespan of your machines and maximize their efficiency, effectively minimizing costly interruptions.
Types of Metal Shear
Alligator shear
So-called because of the hinged jaw used to cut metal, alligator shears are powered by a hydraulic cylinder and are mostly used for cutting long metal stock like l-beams, angle iron, pipe or rebar, or to prepare scrap metal for shredding by lopping off anything the shredder will not accept or non-metal fittings. The cutting motion is actuated by a piston which extends to slowly close the upper ‘jaw’ down alongside the bed. The key strengths of an alligator shear are its cost-effectiveness, strength and durability, it’s drawbacks are its inaccuracy and rough finish.
Metal guillotine
Guillotines consist of a shear table, work-holding device, a gauging device and upper and lower shears. It can be mechanically, hydraulically, or foot-powered and works by clamping the metal with a ram, then moving a metal blade down across a fixed blade to make a cut. The moving blade can either be straight or set on an angle, to decrease the amount of force required to cut a larger piece of metal.
The key strengths of working with a metal guillotine include its speed and cost-effectiveness, which is ideal for high volume production. However, the biggest drawback of a metal guillotine is its tendency to produce a rough edge. These machines are ideal for process parts where aesthetics are not important, or where the metal will go on to be further worked through welding. Always ensure you are employing correct safety measures when operating a guillotine.
Bench shear
A bench mounted shear that offers more mechanical advantage through a compound mechanism, bench shears are ideal for cutting rough shapes from medium-sized pieces of sheet metal. A dynamic piece of machinery, the bench shear can be used for a number of different purposes including 90-degree angle cuts and T-sections as well as cutting both round and square bars.
The strength of a bench shear depends on its size, with larger machines capable of withstanding the highest stresses, but broadly speaking, the key strengths of this type of shearing mechanism are its efficiency and ability to produce a clean cut that’s free of burrs.
Power shears
Ideal for blanking large pieces of sheet metal, power shears are either electrically or pneumatically powered and operated by hand. They work with an upper blade moving towards a lower fixed blade and exerting tension on the cutting material. They are generally used for cutting straight lines or large radius curves.
The key advantages of power shears are their flexibility in cutting curves, efficiency, accuracy, durability and quality finish.
Throatless shear
Perfect for making straight, intricately curved or irregular cuts, the throatless shear differs from the other models on this list because its design allows for the cutting material to be freely moved around.
Snips
Snips are hand tools used to cut sheet metal. There are two different types of snips: tinner snips and compound action snips. Tin snips have long handles and short blades, and are generally used to cut low-carbon tin or mild steel. Straight pattern tin snips are ideal for cutting straight lines or gentle curves, whilst duckbill pattern tin snips are ideal for cutting sharper curves. There are also tin snips known as circle pattern, which cut circles, hawksbill pattern which cut radii on the inside and outside of circles as well as cuts which require sharp turns like when cutting holes in pipes.
The other type of snip is the compound action snip, which is used to cut aluminium, mild steel or stainless steel. This type of snip has a linkage, which increases mechanical advantages. Compound action snips come in three different types:
Straight-cutting (which cut straight and in a wide curve)
Left-cutting (which cut straight and in a tight curve to the left)
Right-cutting (which cut straight and in a tight curve to the right)
Nibblers
Although some nibblers work like tin snips, most work off a punch and die formation. Nibblers work via a blade which moves in a line around a fixed die in a series of up and down punching strokes, ‘nibbling’ away at the material to create a cut.
The advantages of nibblers include their robustness and durability, its ability to produce distortion-free cuts, speed, and low force feed.
How to Maintain Metal Shear
Lubrication
Proper lubrication is the lifeblood of your Metal Shear. It prevents excessive friction, wear, and tear on moving parts. Regularly inspect and lubricate the bearings, gears, and other critical components according to the manufacturer’s recommendations. Using the correct type and amount of lubricant is crucial for optimal performance, as insufficient lubrication can result in premature wear and decreased efficiency.
Blade Maintenance
Blades are the heart of a Metal Shear, and their condition directly affects the quality of the cuts. Periodically inspect the blades for wear, nicks, or damage. If you notice any issues, sharpen or replace the blades promptly. Dull or damaged blades not only compromise the quality of cuts but also put extra strain on the machine, potentially leading to more significant problems.
Hydraulic System
The hydraulic system is the powerhouse of these machines. Check the hydraulic fluid levels regularly and top up as needed. Inspect hydraulic hoses and connections for leaks and wear. Any signs of system issues should be addressed promptly to prevent performance degradation and maintain the reliability of your machine.
Electrical Systems
Ensure that all electrical components, including wiring, switches, and control panels, are in good working condition. Loose or damaged electrical connections can lead to operational disruptions and pose safety risks. Regularly inspect and maintain the electrical systems to keep your machine running smoothly. This includes checking for signs of wear, corrosion, or loose connections.
Cleanliness
A clean machine is a happy machine, and cleanliness is crucial to maintaining your Metal Shear‘s efficiency. Regularly clean the entire machine, removing dust, debris, and metal shavings that can accumulate in and around the cutting area. This improves performance, reduces the risk of fire hazards, and ensures a safer working environment.
Alignment
Proper alignment is critical for achieving precise cuts consistently. Periodically check and adjust the blade alignment to meet the required specifications. Misaligned blades can result in uneven cuts and may cause premature wear of the machine. Regular alignment checks are essential for maintaining the quality and accuracy of your steel products.
Record Keeping
Maintain comprehensive records of all maintenance activities, inspections, and repairs performed on your Metal Shear. This documentation is a valuable resource for tracking the machine’s history, identifying recurring issues, and effectively scheduling preventive maintenance. A well-organized record-keeping system helps ensure that no critical maintenance tasks are overlooked.
Preventive Maintenance Schedule
Developing a preventive maintenance schedule tailored to your specific Metal Shear model and usage is essential. Regularly consult the manufacturer’s recommendations for maintenance intervals and follow them diligently. This helps address potential problems before they become major issues, saving you time, money, and headaches in the long run.
