What is a Hydraulic Alligator Shear?
Previously known as a Lever Shear, an alligator shear is a metal cutting shear that has a hinged jaw. The upper blade of an alligator shear is in scissor motion that is where it gets the name from. It is powered by a flywheel or a hydraulic cylinder. The alligator shears are usually set up as stand-alone shears. The hydraulic ones are the more popular ones as unlike the flywheel powered alligator shears; they don’t run continuously and because of this don’t pose a safety hazard.
Hydraulic alligator shears are used for cutting scrap metal into small pieces. It helps separate different material types because of which you can earn more money from selling scrap metal as you know which ones are more valuable. The hydraulic alligator shears are also ideal for recycling purposes. You can use it to recycle scrap bars, old car radiators, extrusions, tubes, gear boxes and gate valves etc. But that is not all; you can also use the alligator shears for destructing weapons and for cutting cable before stripping or granulation.
Jiangxi HL General Machinery Co. Ltd. manufactures the Q43 Series Hydraulic Alligator Shears adhering to the highest standards of quality. The main components of the alligator shears are the industrially acclaimed German Siemens motor, Schneider Electric and Japanese NOK seals. The shears have been built in such a way that they can heavy duty work, are operator safe and are equipped with blade guards as well as foot-operated switches to ensure utmost safety. The technical performance of our alligator shears have been praised and acclaimed throughout our industry. Also the HL shears have all their working parts enclosed in with optional heavy rubber safety curtains to take it a step further.
Structure & Function of Hydraulic Shears
While the hydraulic shearing machines can be classified into a number of types, the principal structure and function remain the same.
1. Machine Frame
The frame of a hydraulic shear is welded with a steel plate. This includes the right board, left board, worktable, a fuel tank and clamp holder. A push up mechanism, in the form of a hydraulic cylinder and sliding block guide support installed on either side, controls the clearance of blades. For shearing, the hydraulic hold-down cylinder on the clamping device tightly presses the plate.
2. Blade Holder
The fixed upper blade, in case of an alligator shear is in the scissor motion, is connected with the hydraulic cylinder, pass shear force and allow the cutting function. To realize the positioning of the shear plate size, the back gauge mechanism is also fixed.
3. Shear Blade
Both the upper and lower blades are made of high standard steel and have interchangeable cutting knife, this elongates the life of the blade. The blades can shear steel from low carbon steel to stainless steel sheets.
4. Electric System
The electric system provides the power for the hydraulic shears and supplies control power. The electric system also controls the stroke of the shear blade, the scissor movement of the alligator shear and adjusts the shear angle.
5. Hold-Down Cylinder
To keep the plate from moving while the shearing is done, a hold-down cylinder is adopted to press the plate and to keep it firmly in its place.
6. Hydraulic System
The hydraulic system consists of the main oil pump, hydraulic cylinder, hydraulic pipe and pressure cylinder etc. The shearing pressure for the hydraulic equipment is provided by the hydraulic oil pump. The hydraulic cylinder drives the blade holder movement to enable the shearing function. And the hold-down cylinder presses the work piece to make sure the shearing is done with precision.
7. Plate for Finger Protection
On the machine clamp holder, there is a finger protection plate installed. It is used to control the safe distance of the fingers. The finger protection plate’s distance must meet the mechanical safety standard to ensure safe distance of the fingers.
8. Fuel Tank
Behind the shearing machine, the fuel tank is installed on the oil tank base built. The right side of the tank is equipped with the hydraulic oil and an oil gauge. If you add oil up to the middle level of the gauge, it should be fine. On the left side of the tank is the hydraulic oil pump, the main motor and the hydraulic integrated valve block.
