Common Issues with Hydraulic Scrap Shear Blades

Hydraulic shears are important for recycling and processing metal. Sometimes, you might have problems that make Lâminas de Guilhotina Hidráulica para Sucata work poorly. Knowing about these problems helps you fix them fast and keep your tools safe.

Cortes irregulares

You may see jagged or rough edges on cut metal. Sometimes, the pieces are not the same length. The top and bottom blade might not line up right. These signs mean you have uneven cuts.

• Likely Causes:
  • Blade misalignment
  • Worn, chipped, or dull blades
  • Improper blade gap or clearance
  • Uneven hydraulic pressure

If the blade gap is too wide or too narrow, it can cause cracks and rough cuts. Old or broken blades and bad alignment also make cutting worse. When cutting strong steel, you must set the blade gap for the right thickness. Check and adjust the blade gap and alignment often to get clean cuts.

Uneven cuts happen a lot when shearing. They can make your scrap lower quality and waste more metal. Check the blade and alignment often to stop this problem.

Pressure Loss

If your shears do not cut hard enough, or the blade stops before finishing, you might have pressure loss. Sometimes, the machine cannot work at full power or stops halfway.

• Likely Causes:
  • Hydraulic fluid leaks
  • Worn or damaged seals
  • Faulty hydraulic pumps
  • Air trapped in the hydraulic system

Pressure loss is a common problem for Lâminas de Guilhotina Hidráulica para Sucata. Oil leaks and bad seals are usual reasons. If the system cannot build enough pressure, the blade will not cut metal well. Look for leaks and change broken parts to fix the pressure.

Slow Operation

You may see the blade move slowly or each cut takes longer. Sometimes, the controls are slow or the tool holder comes back slowly after cutting.

• Likely Causes:
  • Low hydraulic fluid levels
  • Clogged filters
  • Worn hydraulic components
  • Electrical control issues

Slow operation makes you less productive and can jam the machine. One company in Europe made their shearing faster and cut cycle times in half. They also got 20% more material back. This shows slow operation can hurt your work. Check fluid levels and change filters often to keep your machine fast.

Excessive Noise

If you hear banging, grinding, or squealing, your shears may be too loud. This noise can mean something is wrong inside.

• Likely Causes:
  • Loose or damaged components
  • Insufficient lubrication
  • Worn bearings
  • Misaligned blades

Loud noises can warn you about problems before the machine jams or breaks. Oil the parts and fix problems quickly to stop more damage. Always listen for new sounds when using the shears.

Electrical Problems

Sometimes, your shears lose power, the controls do not work, or you see error messages. These are signs of electrical problems.

• Likely Causes:
  • Faulty wiring
  • Damaged switches
  • Blown fuses
  • Malfunctioning sensors

Electrical problems can stop your shearing and be unsafe. Check the electrical parts often and change broken ones to stop surprise breakdowns.

Dica: Always follow safety rules when checking electrical parts. Never touch bare wires with your hands.

You might also see other problems, like the blade-arm dropping because of hydraulic issues, missing safety locks, or dangers when cleaning by hand. These problems can be very risky. Experts say to use lockpins and safety locks to stop accidents.

If you know about these common shearing problems, you can fix them fast and keep your Lâminas de Guilhotina Hidráulica para Sucata working well.
