With the rapid development of the automobile industry, the quality requirements for key engine components are becoming higher and higher. As an important part of the engine, the quality of the forging directly affects the performance and life of the engine. Therefore, it is very important to carry on strict quality control and management to the production process of the main and auxiliary connecting rod forging.
Raw material quality control
Supplier selection: Select qualified and reputable suppliers to ensure the quality and stability of raw materials. Conduct regular assessment and audit of suppliers to ensure that they meet the quality requirements of the company.
Raw material inspection: Strict quality inspection of purchased raw materials, including chemical composition, mechanical properties, appearance quality and other aspects of the test. Ensure raw material quality meets standard requirements.
Forging process quality control
Mold management: Regular inspection and maintenance of forging molds to ensure their integrity and accuracy meet requirements. The use of qualified dies is the premise of ensuring the dimensional accuracy and surface quality of forging parts.
Forging process control: develop reasonable forging process flow and parameters, and carry out strict process review. In the production process, it is necessary to operate in strict accordance with the process requirements to prevent folding, cracks and other defects.
Post-forging treatment: Proper cooling and heat treatment of the forged connecting rod to eliminate internal stress and improve mechanical properties. Controlling the cooling and heat treatment process is the key link to ensure the forging performance.
Detection and inspection
Dimensional inspection: Adopt high-precision measuring equipment to carry out comprehensive dimensional inspection of forgings. Ensure that the dimensional accuracy meets the design requirements to prevent assembly difficulties or performance degradation due to dimensional out-of-alignment.
Non-destructive testing: The use of ultrasonic, magnetic powder and other methods for non-destructive testing of forging to find internal defects. The defects found should be analyzed and dealt with in time to prevent batch problems.
Performance testing: Mechanical properties testing and metallographic analysis of forgings to ensure that they have sufficient strength and toughness. Performance testing is an important means to evaluate the quality of forging parts, and also an important basis to ensure the stability of engine performance.
Quality management system construction
Improve the quality management system: Establish a sound quality management system, and clarify the responsibilities and work processes of each department. Ensure effective implementation of quality control from raw material to final product.
Training and awareness improvement: Regularly conduct quality awareness and skill training for employees to improve the enthusiasm and ability of all employees to participate in quality control. Let employees fully realize the importance of quality and establish good quality awareness.
Quality information feedback and improvement: establish quality information feedback mechanism, timely collect quality problems in the production process and analyze the causes. Take effective measures to improve the problem, continuously optimize the production process, and improve the stability of product quality.
Quality assessment and motivation: Develop quality assessment standards, and conduct regular assessment of the quality work of each department and staff. Appropriate rewards and incentives will be given to departments and individuals with excellent performance to stimulate the enthusiasm and innovation of employees in quality control.
Continuous improvement and innovation
Process optimization: Continuously optimize forging process and flow to improve production efficiency and product quality. Through the introduction of new technologies, new equipment and new materials, reduce production costs and enhance the competitiveness of enterprises.
Quality data analysis: Use statistical methods to conduct in-depth analysis of quality data to find out the key factors affecting product quality. Improve the effectiveness of quality control by making targeted improvements through data-driven decision making.
Supply chain collaboration: Strengthen communication and collaboration with suppliers to jointly improve the quality of raw materials and components. Through the collaborative optimization of the supply chain, the quality risk is reduced and the competitiveness of the entire supply chain is enhanced.
Customer feedback and market research: Pay attention to customer feedback and market dynamics to understand the performance and potential problems of the product in actual use. This information is fed back to the R&D and production departments to make targeted improvements and innovations to meet market needs and improve customer satisfaction.
Green production and sustainable development: Pay attention to environmental protection and sustainable development in the production process, reduce energy consumption and resource consumption. Promote the use of cleaner production technology and environmentally friendly materials to enhance the image of environmental protection and social responsibility of enterprises.
