The selection of hydraulic oil has a significant impact on the performance of the Alligator scrap metal shearer, which is mainly reflected in the following aspects:
1. Lubricity
High-quality hydraulic oil can provide better lubrication properties and reduce friction and wear between mechanical components. In an Alligator scrap metal shear, the lubricity of the hydraulic oil is critical to ensuring the smooth operation of critical components such as hydraulic cylinders, gears, bearings, etc. Good lubricity helps extend the service life of the equipment and improves the overall performance of the shear.
2. Viscosity and fluidity
The viscosity of hydraulic oil directly affects its fluidity and transmission efficiency. In the Alligator scrap metal shear, different seasons and working environments may require different viscosities of hydraulic oil. For example, in cold areas or winter, hydraulic oil with a lower viscosity should be selected to ensure good fluidity; while in high temperature environments, hydraulic oil with a slightly higher viscosity needs to be selected to maintain its stability. Appropriate viscosity can ensure smooth flow of hydraulic oil in the hydraulic system, reduce energy loss, and improve the working efficiency of the shearing machine.
3. Antioxidation and stability
High-quality hydraulic oils usually have excellent oxidation resistance and stability, and can maintain their performance during long-term use. This is especially important for the Alligator scrap metal shear, because the shear generates a lot of heat and friction during operation, which can easily cause the hydraulic oil to deteriorate. If the hydraulic oil has poor oxidation resistance, it will easily produce sediment or colloid at high temperatures, which will block the oil circuit and affect the normal operation of the hydraulic system. Therefore, choosing hydraulic oil with strong oxidation resistance can ensure the long-term stable operation of the shear.
4. Foaming and cleanliness
The foaminess and cleanliness of the hydraulic fluid also have an impact on its performance in the Alligator scrap metal shear. Hydraulic oil with good foaming properties can quickly defoam during work and prevent bubbles from causing adverse effects on the hydraulic system; while hydraulic oil with high cleanliness can reduce contamination and wear of the hydraulic system by impurities. These features help increase the reliability and service life of the shear.
The choice of hydraulic fluid has a significant impact on the performance of your Alligator scrap metal shear. When selecting hydraulic oil, factors such as its lubricity, viscosity, oxidation resistance, stability, foaming properties, and cleanliness should be comprehensively considered to ensure the normal operation and long-term stability of the shear.
The material and design of the cutting knife have a significant impact on the Alligator scrap metal shear, which is mainly reflected in the following aspects:
Material influence
Hardness and wear resistance: The material of the cutting knife directly affects its hardness and wear resistance. High-hardness materials can resist the reaction force of metal materials during shearing, reduce wear and extend the service life of the tool. For example, steel with appropriate carbon content can significantly improve the hardness and wear resistance of cutting tools after heat treatment, which is especially important for shears that frequently cut high-strength scrap metal.
Red hardness: In a high-temperature environment, the material of the tool must also have good red hardness, that is, it can still maintain a high hardness at high temperatures to avoid softening due to excessive temperature and affecting the shearing effect.
Toughness: In addition to hardness and wear resistance, the tool material also needs to have a certain degree of toughness to resist the impact load during shearing and prevent the tool from breaking.
design impact
Blade shape: The shape of the blade has a direct impact on the shearing effect. A reasonable blade shape can reduce shear resistance and improve shear efficiency and quality. For example, design parameters such as the inclination angle and curvature of the blade need to be optimized based on the properties of the material being sheared.
Blade blunt radius: The size of the blade blunt radius also affects the shear resistance. The larger the blunt radius, the greater the shear resistance, but too small a blunt radius may cause the blade to wear too quickly. Therefore, the appropriate blunt radius needs to be selected according to actual needs during design.
Lateral clearance of the cutting edge: The size of the lateral clearance of the cutting edge has an important influence on the force conditions during the shearing process. Reasonable lateral clearance can reduce shear resistance and improve shear efficiency. However, too large or too small lateral clearance will lead to increased shear resistance and even damage to the tool.
The material and design of the cutting blade have a significant impact on the performance and service life of your Alligator scrap metal shear. When selecting and designing a cutting knife, factors such as the hardness, wear resistance, red hardness and toughness of the material, as well as design parameters such as blade shape, blade blunt radius and lateral clearance of the cutting blade, need to be comprehensively considered to ensure the high efficiency of the shearing machine. ,Stable operation.
