Hydraulic guillotine shears
What are hydraulic guillotine
shears and how do they work?
Simple and convenient operation,
fast cutting speed and high processing efficiency are some of the benefits of
using a hydraulic guillotine.
Hydraulic guillotine shears which
can be called hydraulic crusher or hydraulic cutting machines are a hydraulic
press that makes use of a hydraulic drive to deliver the action. Easy to
operate with high-speed cutting capability and the machines being highly
efficient are a few of the benefits of using hydraulic guillotine shears.
Metalworking
guillotines securly clamp sheets of material in place, with the same movement
of scissors, the blade cuts through the sheet from one side to the other.
In most cases,
the cut piece will drop on to a ramp underneath the cutting area where it can
be reclaimed.
Guillotines can
have hydraulic, pneumatic or mechanical prime movers.
Smaller
guillotines might be manually operated with use of a handle or a pedal. The
minor input by the operative is converted into a major output of force by the
shears blade.
Mechanical
guillotines uses energy that is stored in a revolving flywheel to make the
machine work whereas hydraulic guillotines use pressure delivered by a hyraulic ram to power the device.
In pneumatic guillotines, compressed air is used in the machine.
What kind of guillotine shears are available?
Metal guillotine
Whether hydraulically, foot-powered or mechanically,
guillotines are made up of a shear table, gauging device, workpiece holding
apparatus and lower and upper shears. These guillotines clamp the workpiece via
a ram, after this stage a blade is brought down to a fixed blade which produces
the cut. The moveable blade part of a metal guillotine can be fixed at an angle
or straight, this diminishes the use of the force that is necessary to shear
through a large piece of metalwork.
Bench shear
Shears that are bench mounted give a mechanical
benefit by using a compound mechanism. If you want to cut appoximate shapes in
sheet metal that is of a medium size bench shears are the correct piece of
equipment. It can be used in a multitude of ways such as cutting T-sections,
90-degree cuts. The bench shear will also cut square and round bars.
Alligator shear
Alligator shears are named as such due to the hinged
jaw that cuts the metal. Powered through the use of a hydraulic cylinder, they
are mainly used on long metal stock such as angle iron, re-bar, pipes, I-beams
or in preparation of scrap metal.
Throatless shear
Excellent at producing many different types of cuts.
These shears lets the operator move the workpiece around which means inticate
curves can be produced as well as irregular cuts and straight lines.
Power shears
Pneumatically powered or electrically powered, Power
shears are the go-to for blanking large sheet metal. The upper blade moves
towards a fixed lower blade while producing tension on the metal. Power shears
are ideal for cutting radius curves or straight lines.
How to use Hydraulic Guillotine
shears in a safe manner?
A trained operator who is
accustomed to the machine will be key to producing a good, high quality
product. Knowing how the shears work and how the machine operates is a must. As
well as using the machine, the trained operator must know how to maintain the
machine.
Protective clothing must be worn
while using the machine. Safety helmet and gloves must be worn while using the
machine.
Guillotines are not designed to
cut hard steel, alloy steel or hardened steel, also non-metallic material, the
machine should not be used to cut any of these materials.The metal which is to
be cut by the guillotine should always be clear of weld seams, print marks and
welding slags. Do not overload the machine with pieces that are too thick for
the capabilities of the machine.
The blade that cuts on the
guillotine shears must be sharp and maintained in a sharp fashion at all times.
If the cutting edge becomes dull or damaged it must be repaired or replaced as
soon as possible.
Should the machine have a fault
and not function in a normal manner, the power should be immediately isolated
from the power suppy for inspection purposes.
Should a machine take more than 1
person to operate, one person must oversee the control of the machine.
Should the machine need
adjustment, the machine should be isolated from the power supply and the
operators of the machine must be aware and observe caution to the safety of
their hands whilst manipulating the workpiece.
Do not cut plates of different
specifcations simultaniously in the machine.
Overlapping cutting is also forbidden.
Frequent lubrication by a trained
operator to all parts of the machine should be done every shift. In relation to
the rolling bearing parts which need lubricating by the mechanic every six
months.
The operator must not place their
hands underneath the pressure plate while feeding the guillotin. Once the metal
material is cut an iron plate should be used to press it. Fingers must be kept
200mm (minimum) away from the blade whilst cutting is in progress.
What are the benefits of using
hydraulic guillotine shears?
● Ease of use and high quality work can be prodcued quickly. Hydraulic shearing machines make production of metal cutting in factories simple.
● Mechanical models are very low maintenance which make them very cost effective.
● Smaller machines that do not use lots of floor space, hydraulic shears can produce the same amount of pressure as mechanical shearing machines.
● A large variety of hydraulic shearing machines are avaiable for different sized metal. Metal work pieces are held with clamps which produces high quality workmanship on both smooth cuts and 90 degress cuts.
