In the process of hot die forging, the selection and use of lubricants is crucial to improve production efficiency, extend mold life and obtain high-quality products. This paper will introduce the principles of choosing hot die forging lubricants, and give some suggestions based on practice.
Principles for selecting lubricants for hot die forging
High temperature stability: In the process of hot die forging, the mold and billet temperature is high, so the lubricant must have good high temperature stability, not decomposed and non-volatile at high temperature, and maintain lubrication performance.
Extreme pressure wear resistance: In the process of hot die forging, the metal deformation pressure is large, and the lubricant needs to have excellent extreme pressure wear resistance, forming a tough lubricating film, reducing the friction and wear between the metal and the mold.
Cooling performance: The lubricant should have good cooling performance, be able to take away the heat of the mold and billet surface, reduce the temperature, prevent overheating and deformation.
Environmental protection: Choose environmentally friendly lubricants, do not contain harmful substances, reduce the impact on the environment, in line with environmental protection requirements.
Economy: Under the premise of meeting the performance requirements, try to choose a moderate price and long service life lubricant to reduce production costs.
Practical suggestion
Understand the process requirements: Before selecting the lubricant, fully understand the requirements of the hot die forging process, including temperature, pressure, speed and other parameters, as well as the material and shape of the blank and other factors, to provide a basis for choosing the right lubricant.
Reference experience data: Learn from the industry experience data, understand the performance characteristics of different lubricants and scope of application, avoid blind attempts, reduce the selection risk.
Test verification: Before the actual application, small batch test verification is carried out to observe the lubrication effect of the lubricant, mold wear, product quality and other indicators to ensure that the selected lubricant meets the production requirements.
Cooperate with suppliers: Establish cooperative relationship with professional lubricant suppliers, obtain technical support and product update information, adjust lubricant selection in time, and maintain the best state of production process.
Selecting suitable lubricants for hot die forging is the key to ensure the smooth process of hot die forging. Following the principles of high temperature stability, extreme pressure wear resistance, cooling performance, environmental protection and economy, combined with practical suggestions, suitable lubricants can be effectively selected. The right lubricant choice will increase production efficiency, extend mold life, reduce costs, and help achieve high quality hot die forging products.
