Things You Need To Know About Before Buying A Hydraulic Shear

by Pathlie Lee Business consultant

Investing in hydraulic shears is a massive leap in metal work business. They do not only help you minimise the overall force you would have used to cut the materials but also enables you to maintain accuracy without blurring the edges etc.

When choosing shears however it is vital that you select one with ratings which complement the materials you want to cut. Besides that, also measure the thickness of the metal you'll be cutting. Usually, if you're planning to work on stainless steel, the best recommendation is acquiring a hydraulic sheer rated around 1.5 to 2 times the metal thickness.

Either way, if you're planning to cut aluminium metals/sheets, your hydraulic shear size should average around half the thickness of the metal.

 

Other factors to consider when buying hydraulic shears are;

 

The rake angles

If you're introducing the upper cutting blades across the cutting edges on the lower region, you form an angle which is essential in allowing some part of the metal getting exposed to the blades when cutting. The angle formed here is the rake angle. It's mainly beneficial in helping you minimise the overall force you will need to cut extended lengths.

 

Now, if you wanted to use little force to cut the material, you'll set the angle at 'zero rake angle'.This is because the machines are designed to shear straight parts for quick cycle times.

 

An excellent hydraulic shear should, however, have a rake angle averaging around 0.25 of angle for each foot.If your rake angle margin is higher, you stand risks of having twisted or bowed sheets.Finally, if you prefer buying shears with variable rake angles, check to ensure the capacity it could handle at its lowest.

 

The blade gap adjustments

When shearing metal blades, the force you'll need to cut the pieces is determined by the offset.i.e., if the offset between the upper, and lower blades is high, you'll need little force to cut the material, and vice versa. The more the blade gaps widen, the more you will begin to notice blurring on the sheared blades.

 

Moreover, if you used the blade gaps to close, then you will need more forces than the shears can manage to fracture the material. Since the breaking strengths of materials vary, it's critical that you set the blade gap settings in regards to the metal type, and its thickness to get clean cut blades.

 

Note that all hydraulic sheers can easily change blade gap adjustments through manual shimming, bed blade settings or the powered blade gap adjustments.The materials you need to shear should guide you in choosing the best hydraulic shear for these operations.

 

Control

If you're new in using the hydraulic shears, it's vital that you choose a used hydraulic shear that is easy to operate. Your supplier should help you choose a tool that will not pose any complications during shearing

 

Your vendor

Finally, your vendor should be someone with a background in metal work.He/she should know how to match metal thicknesses with the best hydraulic shears. Besides they should also help you with productivity tips on how to get the best from your new machine.
