In the operation of the aluminum wire drawing machine, to ensure the best drawing effect, it can be controlled and optimized from the following aspects:
First, material preparation
1. Select high-quality aluminum wire: Select aluminum wire with stable quality and high purity as raw materials to ensure that there are no impurities, pores and other defects inside the aluminum wire to reduce the fracture and surface defects in the wire drawing process.
2. Pretreatment: Necessary pretreatment of aluminum wire, such as cleaning, oiling, peeling, etc., to improve the contact effect and drawing quality of aluminum wire and die.
Second, equipment debugging
1. Mold selection: According to the specifications of the aluminum wire and the required wire drawing diameter, choose the appropriate wire drawing mold. The precision and wear resistance of the die have a direct influence on the drawing effect.
2. Tension adjustment: Reasonably adjust the tension system of the wire drawing machine to ensure that the aluminum wire is subjected to uniform tension during the wire drawing process, to avoid excessive tension resulting in aluminum wire breakage or too small tension affecting the wire drawing effect.
3. Speed control: According to the material and specifications of the aluminum wire, adjust the running speed of the wire drawing machine to match the physical characteristics of the aluminum wire to avoid surface cracks caused by too fast speed or poor surface quality caused by too slow speed.
3. Operation specifications
1. Professional training: Operators need to undergo professional training, familiar with the operating procedures and safety specifications of the equipment, and be able to skillfully deal with various operational problems.
2. Stable operation: During the wire drawing process, maintain the stable operation of the equipment and avoid sudden acceleration or deceleration to reduce the impact on the aluminum wire.
3. Regular cleaning: regularly clean the debris and carbon deposits on the mold and drawing wheel to keep the mold clean and sharp to improve the drawing effect.
Fourth, process optimization
1. Drawing times: According to the material of aluminum wire and the required drawing effect, reasonable arrangement of drawing times. Too many drawing times will result in surface ripples and streaks, while too few times may not achieve the desired surface quality.
2. Cooling system: Ensure the normal operation of the cooling system, control the temperature during the wire drawing process, and avoid the embrittlement or fracture of the aluminum wire due to overheating.
3. Quality inspection: In the drawing process and after the drawing is completed, the quality of the aluminum wire is tested, including size, shape, surface quality, etc., to ensure that the drawing effect meets the requirements.
5. Equipment maintenance
1. Regular inspection: Regular inspection and maintenance of the wire drawing machine, including power lines, motors, transmission systems, lubrication systems, etc., to ensure that the equipment is in good working condition.
2. Replace the worn parts: replace the worn mold, guide wheel and other parts in time to ensure the stability and consistency of the drawing effect.
3. Lubrication maintenance: Regular lubrication and maintenance of the lubrication parts of the equipment, reduce friction and wear, and extend the service life of the equipment.
In summary, through the efforts of material preparation, equipment debugging, operation specifications, process optimization and equipment maintenance, we can ensure that the aluminum wire drawing machine achieves the best drawing effect in the operation process.
