Shear blades is a common part of fabricating equipment that is found in different metal forming plants; from tube mills to small fabricators.
In this article, we’re going to tackle on how to maintain these shear blades.
1. Understand your Machine
When it comes to machines, it is important to understand the function, design and operation of your machine. The main cause of failure of the machine is overloading it beyond the OEM’s parameter. Always follow the OEM’s load recommendation of the machine and adjustments should be done regularly before you start with the process. Misuse of lubricant can cause significant damage to your machine and must be follow by the recommended OEM.
2. Regular Inspections and Documentation
Before start with your task, it is important to schedule daily documentation and inspections to your machine. Areas should be inspected including the shear’s ability to execute all functions of operation, bearings and all emergency functions.
3. Blade Setting
Setting the Shear Blade properly is the key to extending the machine and the blade life. Clearances for blade cutting affects the drive, ram, tooling and the cut quality. Remember, before setting the blade seat should be checked for flatness and to ensure that the tooling is seated properly to eliminate blade chipping caused by shifting during cutting.
4. Follow a Maintenance Plan
Maintaining your shear blade needs a proper guide to keep it on tip-top shape. Here are some them:
The following parts of a shear require regularly scheduled maintenance:
5. Repair Blade Immediately if Damaged
When damage, wear, or out-of-adjustment conditions are found, the shear should be immediately repaired or adjusted. Most catastrophic failure is caused by putting off simple repairs. Addressing repairs quickly is almost always less expensive than the cost of correcting the damage that can take place when repairs are ignored or put off. Additionally, operator safety depends on timely repairs.
Keeping the shear productive can be accomplished by performing these simple tasks. When a shear is maintained properly, replacement costs and catastrophic failure are avoided.
