Advantages of Hydraulic Shearing Machine Over The Regular Mechanical Models

A shearing machine is an industrial equipment with rotary disks and blades used to cut hard iron sheets and metal bars. The term shearing means to apply a high pressure tool on a metal bar once to remove a part of the metal. All metal shears use the same technique in cutting where there is a fixed upper blade, a lower blade and an adjustable clearance separating the two. When a force is applied on the upper blade it forces the lower blade to cut and separate the metal into two.

 

Shearing machines are categorized depending on the shape of its blade, linear or circular.

 

Linear shearing machines are used to cut metal with a thickness of over 2mm and they are operated with hydraulic power or hand operated machines for thinner metals.

 

Circular shearing machines are used to cut circular blanks and rings from metal and are operated by an electric motor. The best types of metal for shearing are bronze, aluminum, brass and mild steel. Metal shearing is cost effective and easy and hence preferred in industries and even homes.

 

Types of Shearing Machines

 

  1. Bench Shear – The word bench is because the machine is mounted on a bench to increase its mechanical ability. It is used to cut rough shapes of medium sizes of metal. However, small bench shearing machines are fitted with ground cutting blades and are light weights making it easy to have clean and fast cuts.

 

  1. Guillotine – This means that the machine is hand or foot powered and sometimes mechanically powered. The material to be cut is first cramped with a ram and a moving blade goes down and shears the metal. a power shearing machine consists of a shear table to put the material being sheared, a a holding device to hold the material in place to avoid movement, a gauging device to make sure the material is in the right place and the lower and upper blades to do the cutting.

 

  1. Power Shears – This type of a shearing machine is electrically powered to shear large pieces of metal regardless of size. Alternatively they can be powered with hydraulics to cut metals that are too bulky for transportation.

 

  1. Throat – Less shear- This means that the metal being cut can be moved around the cutting blade freely so it’s flexible. It’s used for complex cuts and curves.

 

Advantages of Using Hydraulic Shearing Machines Over Mechanical Models

 

  • Hydraulic shearing machines are fast and accurate and make it easy to cut a lot of metal in factories.
  • Hydraulic shears don’t require a lot of maintenance as mechanical models and hence are cost effective.
  • Hydraulic shears are usually compact machines and hence take up less space even though they apply the same kind of pressure as mechanical shearing machines.
  • Hydraulic shearing machines secure metal with cramps while cutting hence ensuring smooth cuts and even 90 degrees cut. There are a wide variety of hydraulic shearing machines in the market to cater for all sizes of metal.

 

How to Use Hydraulic Shearing Machines Safely?

 

  • Always have specialist operators to work on the machine
  • Maintain cleanliness in the machine and follow the operating rules to avoid hazards.
  • Always make sure to switch off power of the machine after use.

 

Conclusion:

 

Hydraulic shears are more effective and easier to use than mechanical machines but should be handled with care by qualified personnel only.

The Facts about Press Brake Machinery

Most of the time metal needs to be formed before it can be used. There are a lot of ways that metal is formed. The most common is to use a machine press. A press uses some kind of force to change the shape of the metal. There are several different presses and methods to pressing metal. One kind of press is the press brake, also known as the brake press. This machine press bends sheet metal into the desired shape.

 

Angles formed with this kind of press can be extremely accurate. Depending on what kind of die is used, multiple bends can be made at one time. Press brake machinery has two frames that are the sides. They are attached to a table on the bottom with a ram or beam on the top.

 

The die and punch are attached to the table and the beam. The sheet metal goes in between the two, the punch lowers and the metal is formed into the shape of the die. When it comes to basic operation, there are 4 basic types. They break down as to the way that force is applied to the metal to bend it. Not all the methods work for all applications. Some of them are slower or less accurate than others.

 

One type of brake press machinery is the mechanical press. This kind of press has a flywheel inside the electric motor. Energy is applied to the flywheel and a clutch is used to engage the wheel so it moves a crank to lift the beam up and down. This kind of press is fast and the most accurate.

 

A hydraulic press uses two cylinders that are mounted on the sides of the press. The cylinders are synched up so that they move together. A hydraulic press is slower than a mechanical press. A pneumatic press is similar except instead of using fluid.

 

The servo-electric type of press has a belt drive or ball screw that is driven by a servomotor. The best uses of the servo-electric and pneumatic brakes are jobs that don’t need as much pressure, or tonnage, placed on the ram. Until recently, the mechanical presses were most commonly used. This is because they are fast and highly accurate. In the past hydraulic presses were much slower because they had to wait to reset. But advances in hydraulics have markedly reduced that waiting period.

 

The advances of computer controls have also made hydraulic press brakes much more accurate. They are also the safest choice. One piece of press brake machinery can be used for a number of jobs. All it takes is changing the punch and die. The punch goes on the ram. It pushes the metal down into the die.

 

The punch gives the bend it’s inside angle and the die gives it the outside angle. However, depending on the bending process, whether it is air bending or bottoming, a die might not be needed. A press brake is used to fold and bend sheet metal into new shapes. Things like brackets and cases for electronics are made this way. There are different kinds of press brake machinery as well as different processes and dies.
