What Is An Alligator Metal Shear?

An alligator shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. The jaw size can range from 4 to 36 in (100 to 910 mm) long. They are generally used to cut ferrous members, such as rebar, pipe, angle iron, or I-beams.

Main Features of the Alligator Shear Machine

This alligator shear is mainly used in the waste material recycling processing industry. Cold cutting of various small and medium-sized steel plants such as round steel, square steel, channel steel, angle steel, I-shaped steel, steel plates, steel pipes, and other waste metals.

This equipment uses hydraulic transmission. Compared with mechanical transmission shears, it has the advantages of small size, lightweight, low inertia, low noise, stable movement, safe operation, and use, and easy to achieve overload protection.

This cutter has the functions of manual operation and automatic operation. Its operation method is convenient and simple. The metal scissors’ mouth can be cut and stopped at any position during the work. According to the size of the material being cut, the size of the cutting mouth can be arbitrarily controlled to achieve high work efficiency.

Different Types of Metal Shears

Alligator Shear
Let’s kickstart our metal shearing expedition with the mighty alligator shear. Its hinged jaw resembling a powerful reptile makes this hydraulic marvel ideal for cutting l-beams, angle iron, and rebar. Powered by a hydraulic cylinder, the cutting motion is initiated by a piston extending to close the upper jaw alongside the bed gradually.
The alligator shear boasts cost-effectiveness, strength, and durability, making it a go-to choice for preparing scrap metal for shredding. However, its Achilles’ heel lies in occasional inaccuracy and a rugged finish. Despite these trade-offs, the alligator shear stands tall as a robust contender in metal cutting.

Bench Shear
Mounted for mechanical advantage through a compound mechanism, bench shear is a craftsman’s delight. Ideal for shaping rough forms from medium-sized sheet metal, the bench shear flexes its muscles in various applications, from 90-degree angle cuts to T-sections. Besides, it effortlessly slices through both round and square bars.
The strength of a bench shear scales with its size, capable of withstanding the highest stresses. Broadly speaking, its efficiency and knack for producing clean cuts free of burrs make it an invaluable asset in metal shearing.

Power Shear
The power shear takes center stage in the realm of blanking large pieces of sheet metal. It’s powered either electrically or pneumatically and operated by hand. This tool works magic with an upper blade moving towards a lower fixed blade, exerting tension on the cutting material. Its prowess lies in cutting straight lines or large-radius curves.
Flexibility, efficiency, accuracy, durability, and a top-notch quality finish are the key advantages that set power shears apart. Imagine the ease of maneuvering through curves, the efficiency of accurate cuts, and the durability to withstand metal fabrication demands.

Throatless Shear
The throatless shear is perfect for crafting straight, intricately curved, or irregular cuts. It introduces a design innovation that allows free movement of the cutting material. Diverging from traditional models, this shear adds a layer of versatility to metal shearing tasks. Picture the freedom to move the material around, enabling precision in creating intricate shapes and cuts.

Metal Guillotine
With a ram and blade, the metal guillotine clamps metal and cuts with precision. It can operate mechanically, hydraulically, or by footpower. Its strengths lie in speed and cost-effectiveness, making it ideal for high-volume production.
However, its biggest trade-off is that it has a tendency to produce a rough edge. These machines find their sweet spot in processing parts where aesthetics take a back seat or where the metal undergoes further refinement through welding. Safety measures are paramount when operating a metal guillotine, ensuring a smooth and secure metal-cutting process.

The Operation Principle of Hydraulic Alligator Shearing

The alligator shears are very efficient at working, but many people don’t know how to use the hydraulic alligator shears.

Safety Tips to Follow When Using Alligator Shears

Alligator shears may be easy to cut through sheet metal. Also known as lever shears, they feature a lever-like blade. You can cut pieces of sheet metal by placing them through the jaws of alligator shears. When engaged, the blade will slide through the sheet metal. While alligator shears are easy to use, however, they require proper safety precautions to protect against injury.

Inspect the Guard
Before using alligator shears, take a minute to inspect the guard. The Occupational Safety and Health Administration (OSHA) requires alligator shears to feature a guard. The guard is located around the blade. It's designed to block projectiles of metal waste. When cutting sheet metal, small pieces of debris may shoot out from the blade. The guar will block these projectiles so that they don't cause injury. If the guard is missing or broken, avoid using the alligator shears

Keep Hands Away From Blade
Like with all cutting tools, you should keep your hands away from the blade when using alligator shears. Alligator shears have an ultra-sharp blade. After all, they are used to cut through sheet metal. Most alligator shears are capable of cutting through both aluminum and steel. To protect against injury, keep your hands away from the blade at all times when using alligator shears.

Wear Impact-Resistant Safety Glasses
Don't forget to wear impact-resistant safety glasses when using alligator shears. Cutting sheet metal with alligator shears can create projectiles. While alligator shears are required to have a guard, some of these projectiles may make their way past this barrier and into your eyes. Impact-resistant safety glasses will protect you from eye injuries due to projectiles. As their name suggests, impact-resistant safety glasses are designed to withstand impact without breaking.

Identify the Emergency Stop Button
Most alligator shears have an emergency stop button. When pressed, it will automatically disable the cutting blade. You should identify this emergency stop button before using alligator shears. Make sure you know where it's located in case of emergency. If the alligator shears malfunction, you can press the emergency stop button to disable the cutting blade.

Follow Maintenance Requirements
All alligator shears have maintenance requirements. Depending on the particular type, you may need to change the oil and apply lubricant. You'll probably need to replace the blade on occasion as well. Make sure you stay on top of these maintenance requirements. Neglecting to maintain alligator shears can result in damage or bodily injury.

Maintenance Method of Alligator Metal Shears

Before using the machine, the operator of the metal shearing machine should be familiar with the specific working process of the machine, carefully implement the maintenance system of the hydraulic metal shear machine, and strictly observe the safe operating regulations of the machine. In this way, the service life of the machine can be prolonged, production efficiency can be improved, and safe production can be guaranteed. To this end, our scrap metal recycling machinery manufacturers recommend that users establish maintenance and safe operating procedures for hydraulic shears. Consciously train operators to familiarize them with the structure and operating sequence of the machine.

When working a single time. When the knob is set to the single working position, each action cycle of the shearer needs to be pressed to complete the button, and each press completes one action. (Pressing material-shearing-pressing material release-shearing return is one working cycle).

When working continuously. Set the knob to the continuous working position, and the shearing machine will automatically complete the return from pressing to cutting and take on the next action. The oiling points marked on the metal shears should be lubricated with ordinary oil before going to work every day or two days to prevent excessive wear for a long time and cause equipment damage.

The material to be cut is strictly beyond the specification range specified in the machine’s instruction manual. When cutting irregular metal waste, prevent metal material from pressing on any part of the metal cutting machine before work, and timely remove the materials on the cutting platform and the inside of the rack to avoid damaging the machine and causing unnecessary losses.
