The quality control and process optimization of the copper large wire drawing machine is a complex but crucial process, which covers multiple links from raw material selection to the final product inspection. The following is a detailed analysis of this process:

Quality control

1. Raw material control: Ensure the use of raw materials that meet specifications and standards. The quality of raw materials directly affects the final quality of the product. Therefore, suppliers should be strictly screened and raw materials should be subject to regular quality inspections to ensure they meet production requirements.

2. Process flow control: The process flow of the wire drawing machine has a crucial impact on product quality. It is necessary to ensure the stability and continuity of the technological process and avoid fluctuations and interruptions during the production process. At the same time, strict process control should be carried out for each production link, including the setting of parameters such as temperature, pressure and speed. During the wire drawing process, special attention should be paid to the temperature, concentration and cleanliness of the lubricant, as these factors have a direct impact on the drawing effect.

3. Equipment maintenance and Inspection: During the production process of the wire drawing machine, regular maintenance and inspection are required, including lubrication and tightening of mechanical components, as well as inspection of electrical parts. Ensure that the equipment operates in a safe environment to avoid the impact of accidents on product quality.

4. Product Inspection: During the production process, regular quality inspections of the products should be carried out, including tests on appearance, size, performance and other aspects. For substandard products, rework or scrapping should be carried out in a timely manner to avoid affecting subsequent production.

Process optimization

1. Optimization of wire drawing speed: The selection of wire drawing speed has a significant impact on the working efficiency and product quality of the wire drawing machine. Both excessively high and low wire drawing speeds may lead to problems during the wire drawing process. Therefore, it is necessary to select an appropriate speed based on specific circumstances.

2. Optimization of mold selection: The choice of mold determines the specifications and quality of the final product. For copper wires of different specifications, molds of corresponding sizes need to be selected to ensure the accuracy and consistency of the products.

3. Optimization of lubricant usage: During the copper wire drawing process, the application of lubricants can reduce frictional resistance, protect the die and workpiece, and enhance the drawing effect. The selection of the appropriate type of lubricant and its application method is crucial for the smooth progress of the process.

4. Optimization of die matching principles: Fully utilize the plasticity of metals, adopt the fewest drawing passes, and enhance production efficiency; At the same time, it is necessary to ensure that the stretched wire can meet the required size and shape, and have good surface quality.

In addition, through efforts in data analysis and improvement, personnel training and management, environmental control, and the construction of a quality management system, the quality control and process optimization level of the copper large wire drawing machine can be further enhanced.

In conclusion, the quality control and process optimization of the copper large wire drawing machine is a complex process involving multiple links and factors. Through strict measures such as raw material control, process flow control, equipment maintenance and inspection, product inspection, and process optimization, high-quality fine copper wire products can be produced.
