Ultimate Guide to Hydraulic Shearing Machine

by Pathlie Lee Business consultant

Hydraulic shears are widely being used in manufacturing and construction industries and it’s for all the right reasons. These machines cut, score sheet metal quickly and more accurately than mechanical models. They are also designed for safety, are highly reliable and don't require a lot of maintenance. Hydraulic shearing machines also cost less than other shears because they are inherently cheaper to build.

That said, there are still many people out there that don’t know much about hydraulic shears: What they are, the difference between hydraulic shears and mechanical shear and what to look for when buying a hydraulic shear. If you are not familiar with the hydraulic shears and want to buy one, here is a guide that will help you know everything about them.

What Are Hydraulic Shears?

Hydraulic Shears, like mechanical shears, are multipurpose devices used to cut alloys and other sheet metal. Also, like mechanical shears, hydraulic shearing machines are comprised of two blades: one on the lower end that is attached on the bed, and one on the upper side that is attached firmly on the moving ram.

What’s the Difference between a Hydraulic Shear and Mechanical Shear?

Hydraulic shearing models, as the name suggests, are powered by a hydraulic cylinder. Mechanical models, on the other hand, are driven or powered by a rotating motor, which is triggered by a flywheel clutch combination.

What to Consider When Buying a Hydraulic Shear

Whether you are planning to buy a new or used hydraulic shear, here are four factors that will help you make the right decision. :

•    The Main Frame: This is the part that supports all the components in a shearing machine: drive system, blades, and bed. Ensure the sharing machine you choose has a tough and well-built frame. Weak mainframes are susceptible to having cracked beds, fractured side frames, and wrapped rams. 

•    The bed: The bed is the part that you will be working on as you introduce material to the shear blade. This part also contains the lower shearing blade. Your shear’s bed should be heavy and solid.

•    The Squaring Arm: This is the part that ensures the material being sheared is perfectly square to the shearing blades. Make sure the squaring arm’s length is right. Typically the length of the squaring arm should equal the length of the blades.

•    Blades: Shearing machines typically have blades that have two sharp sides or four sides for use. Make sure the machine you choose has the type of blades that you want. Also, ensure the blades can be resharpened or replaced.

Safe Operation Rules You Must Follow When Using a Hydraulic Shear

•    Lubricate the lubricating parts according to lubrication provisions

•    Before starting, test to see if the machine is working properly. If everything is working well, you can start the cutting operation.

•    Don’t use your hydraulic shear to cut rods, non-metal materials, explosive articles or over thin working pieces. They will damage the machine and can even injure you.

•    The blades should always be sharp. Also, the bed is not allowed to have a protruding burr or any type of scar.
