What are the contents of quality management for large shaft forgings?
Core Tip: Shaft type large forgings are workpieces or blanks obtained through forging and metal workpieces. Applying pressure to metal blanks can cause plastic deformation, thereby altering their mechanical properties. According to the raw material during processing
Shaft type large forgings are workpieces or blanks obtained through forging and metal workpieces. Applying pressure to metal blanks can cause plastic deformation, thereby altering their mechanical properties. According to the temperature of the blank during processing, forgings can be divided into cold forging, hot forging, and hot forging. Cold forging is usually carried out at room temperature, while hot forging is carried out at a temperature higher than the recrystallization temperature of the metal workpiece. Let's follow the editor to briefly understand how to protect the appearance and quality control of large shaft forgings?
Storage of large shaft forgings: A special storage platform with wooden or painted carbon steel supports or rubber pads must be provided to isolate them from carbon steel and other metal materials. When storing, the storage location should be easy to lift, relatively isolated from other material storage areas, and protective measures should be taken to prevent stainless steel from being contaminated by dust, oil, and rust.
Lifting: Special lifting tools such as belts and specialized chucks should be used. It is strictly prohibited to use steel wire ropes to avoid scratching the surface, and please avoid collisions and scratches.
Transportation: During transportation, hand carts, batteries, and other transportation tools should be used, and isolation and protection measures should be taken to prevent dust and oil pollution of stainless steel. Dragging is strictly prohibited to avoid collision or abrasion.
Processing area: The processing area for forgings should be relatively fixed. The platform in the forging processing area should be isolated using rubber pads. Strengthen the fixed management and civilized production of the processing area to prevent damage and pollution to large shaft forgings.
Mechanical processing: Effective measures should be taken to prevent scratches and wrinkles on the surface of stainless steel during the process of coiling and bending.
After the design of large shaft forgings is completed, quality control should be carried out to ensure that the provided forgings have the specified dimensional accuracy and excellent performance requirements in the drawing. That is to say, it is necessary to control the entire production process from raw material selection to post forging heat treatment to ensure the stability of production quality and product integrity. So what are the contents of quality management for large shaft forgings?
1. Forging quality
The main purpose of quality assurance is to ensure that the dimensional accuracy, mechanical performance, design drawings, and other special requirements specified in the technical requirements of the order unit meet all product requirements
2. Quality Management
Quality management is the regular measurement and inspection of variable parameters in production and the geometric dimensions, surface quality, and mechanical properties of forgings. Compare the measurement results with the standards and technical requirements to determine whether certain factors in the forging production process need to be changed, in order to achieve quality control of forging and ensure that the fluctuation of forging quality does not exceed the technical requirements of the ordering unit.
