How to test and control the quality of crankshaft forgings?

Quality inspection and control is an important part to ensure that every link in the production process of crankshaft forgings meets the standards and customer requirements. The following will introduce the key steps and technical requirements for quality inspection and control of crankshaft forgings.

First, quality testing

Geometric size detection: Through the use of measuring tools, such as calipers, micrometers, etc., to accurately measure the length, diameter, Angle and other geometric dimensions of the crankshaft forging to ensure that it meets the design requirements.

Surface quality inspection: using visual inspection, scanning and other methods to check whether there are cracks, pores, inclusions and other defects on the surface of the crankshaft forging. At the same time, the surface roughness is tested to ensure that it meets the requirements of use.

Mechanical performance test: Through tensile test, hardness test, impact test and other means, test the strength, toughness, hardness and other mechanical performance indicators of crankshaft forgings to ensure that it meets the design requirements and customer standards.

Non-destructive testing: ultrasonic testing, magnetic particle testing, X-ray testing and other non-destructive testing methods are used to detect the internal quality of crankshaft forgings and find internal defects and problems.

2. Quality control

Raw material control: Strict inspection of raw materials entering the factory to ensure that their chemical composition, mechanical properties, etc., meet the requirements. At the same time, the establishment of raw material quality files, traceability management of raw materials.

Production process control: in forging, heat treatment, machining and other production processes, establish strict operating procedures and quality control mechanism. Discover and solve problems in time by using data statistics and analysis in the production process.

Quality management system: Establish a sound quality management system, including document control, identification management, nonconforming product treatment and other links. Improve the quality level of crankshaft forgings and customer satisfaction through continuous improvement of the quality management system.

Staff training and quality improvement: Regularly conduct quality awareness training and technical training for employees to improve their quality and skill level. At the same time, establish an employee incentive mechanism to encourage employees to actively participate in quality improvement activities.

3. Examples of crankshaft forging quality inspection and control

A crankshaft forgings production enterprise has perfected the quality inspection and control system by introducing advanced testing equipment and excellent technical personnel. In the production process, they have adopted a series of quality control measures, such as strictly controlling the quality of raw materials, strengthening the production process management, and improving the quality management system. Through these efforts, the quality of the company’s crankshaft forgings products has been significantly improved, and customer satisfaction has also been greatly improved.

In short, quality inspection and control of crankshaft forgings is the key link to ensure its quality and stability. Enterprises should start from the aspects of raw material control, production process control, quality management system construction, etc., and effectively improve the quality level of crankshaft forgings to meet customer needs and automobile manufacturing standards. At the same time, we continue to promote technological innovation and quality improvement to enhance the core competitiveness and market share of crankshaft forgings.
