As the core component that directly contacts the material, the blade is subjected to shearing impact and friction for a long time, which can easily lead to wear, chipping, or dulling. Especially when shearing materials with high hardness, the wear rate will be significantly accelerated. Worn blades will result in an uneven sheared surface, burrs on the material, and even affect the shearing accuracy.
- Regularly inspect the blades and sharpen or replace them as needed based on wear levels.
- Simultaneously, control the hardness range of the materials being sheared to minimize unnecessary wear.
Seals in the hydraulic system are responsible for isolating hydraulic oil and preventing leakage. Affected by hydraulic oil temperature changes, pressure fluctuations, and long-term compression, seals are prone to aging, deformation, or damage, leading to hydraulic oil leakage and affecting equipment power output. Damaged seals may also allow air to enter, causing unstable hydraulic system pressure.
- Regularly check the seals' sealing performance and replace them immediately if leaks are found.
- Use suitable hydraulic oil to avoid impurities accelerating seal aging.
The guide slider provides precise guidance for blade movement, ensuring smooth shearing action. Over time, wear occurs between the slider and the guide rail, leading to increased clearance, blade movement deviation, decreased shearing accuracy, and in severe cases, abnormal noise.
- Maintain the cleanliness of the slider and guide rail daily, add lubricating oil periodically to reduce friction.
- Adjust or replace the slider promptly if abnormal clearance is detected to ensure guiding accuracy.
The feed roller is responsible for conveying materials. Its surface, constantly rubbing against the material, is prone to wear and slippage, affecting feeding stability and accuracy, especially when conveying rough or impurity-laden materials. Wear on the roller surface can cause material conveying deviation, increasing shearing errors.
- Regular cleaning of the feed roller surface is necessary, along with checking for wear.
- Grinding or replacement is required when necessary.
- Simultaneously, controlling the feeding speed and material flatness can reduce roller wear.
