In the process of wire drawing, optimizing the cooling lubrication effect is a key link to ensure smooth production, improve product quality and extend equipment life. The following are some specific optimization measures:
1. Choose the right coolant/lubricant
Performance requirements: Coolant/lubricant should have good cooling, lubrication and rust resistance. High-quality coolant can reduce friction at the same time, quickly take away heat, prevent local overheating, and prevent oxidation of the metal surface.
Type selection: Based on material characteristics and process requirements, choose water-based or oil-based coolant/lubricant. In general, water-based lubrication is better than oil-based lubrication in terms of cooling effect, but oil-based lubrication may be better in terms of lubrication performance.
2. Optimize the cooling system
Flow rate and coverage: Ensure that the coolant adequately covers the drawing area and increase the cooling effect by increasing the circulation rate of the coolant or adjusting the spray Angle.
System maintenance: Regularly clean the cooling system to prevent the accumulation of impurities (such as metal chips, sludge), affecting the flow and cooling efficiency of the coolant. At the same time, the coolant is replaced regularly to ensure long-term stable operation of the system.
3. Precise control of cooling parameters
Temperature monitoring: The temperature monitoring system equipped with modern wire drawing equipment can monitor the temperature changes of the workpiece and the mold in real time, and adjust the flow rate and spray mode of the coolant according to the temperature.
Temperature range: The temperature of the coolant/lubricant is controlled within the appropriate range to avoid excessive or too low to adversely affect the cooling effect.
4. Lubricant supply and management
Adequate supply: Ensure a continuous and stable supply of lubricant throughout the drawing process to avoid increased friction and temperature due to insufficient lubrication.
Viscosity control: Regularly check the viscosity of the lubricant to avoid poor fluidity due to excessive viscosity, affecting the lubrication effect. If there are too many impurities in the lubricant, it should be replaced or treated in time.
5. Mold cooling and matching
Mold cooling: strengthen the cooling of the mold, reduce the mold temperature, and reduce the risk of wire breakage caused by overheating of the mold.
Mold matching: Select the mold that matches the material characteristics and process requirements to ensure uniform force during the drawing process and reduce the problem of wire breakage caused by mold mismatch.
6. External condition control
Workshop environment: Keep the workshop environment clean and reduce the impact of dust and impurities on the coolant/lubricant. At the same time, the temperature and humidity of the workshop are controlled to create a good external environment for the drawing process.
To sum up, optimizing the cooling lubrication effect in the drawing process needs to start from many aspects, including selecting the appropriate coolant/lubricant, optimizing the cooling system, accurately controlling the cooling parameters, strengthening the lubricant supply and management, focusing on the mold cooling and matching, and controlling the external conditions. The implementation of these measures will help to improve production efficiency and product quality, reduce the line break rate, and extend the service life of the equipment.
