Product Production Flow Chart

I. Overall Process Framework

Raw Material Preparation: Obtain the raw materials used for production to prepare for the subsequent processing.

Blank Production: Gradually transform the raw materials into blank pieces close to the shape of the finished product through a series of processing technologies.

Performance Optimization: Conduct heat treatment on the blank pieces to improve their mechanical properties.

Fine Processing: Further process the blank pieces after heat treatment to meet the accuracy requirements of the finished product.

Post-Processing and Packaging: Clean and inspect the finished product, pack it after ensuring its quality meets the requirements, so as to facilitate storage and transportation.

II. Detailed Process Steps

(1) Raw Material Preparation

This is the starting point when the raw materials enter the production process. Prepare the required raw materials, such as plates and bars.

(2) Blank Production

Blanking

Operation: According to the product design requirements, use cutting equipment (such as shearing machine, sawing machine, etc.) to cut the raw materials into the required approximate size and shape to obtain the blank pieces.

Output: Blank pieces with the preliminary size and shape meeting the requirements.

Forging

Operation: Heat the blank pieces after blanking to the appropriate forging temperature range, and apply pressure to the blank pieces with forging equipment (such as air hammer, friction press, etc.) to make them have plastic deformation, further refine the grains, improve the internal structure of the metal, improve the mechanical properties of the material, and make them close to the shape of the finished product.

Output: Blank pieces with improved internal structure and properties after forging deformation and closer to the shape of the finished product.

Machining

Turning: Use lathe to perform turning processing on the forged blank pieces to remove excess materials and make the outer circle, inner hole, end face and other parts of the blank pieces meet certain size accuracy and surface roughness requirements.

Milling: Perform milling operation on the blank pieces through milling machine to process planar, groove, gear and other shape features, and further accurately control the shape and size of the blank pieces.

Drilling: Use drilling machine to drill various required holes in the blank pieces to meet the assembly or functional requirements of the product.

Output: Blank pieces with more accurate size accuracy and shape after multiple machining technologies, which are basically close to the shape of the finished product, but the surface accuracy and some properties still need to be further processed.

(3) Performance Optimization

Heat Treatment

Quenching: Heat the blank pieces after machining to above the critical temperature, keep them warm for a certain period of time and then cool them rapidly to make the material obtain high hardness and high strength. But at this time, there will be large internal stress in the material and the toughness is poor.

Tempering: Heat the blank pieces after quenching to a certain temperature range below the critical temperature, keep them warm for a certain period of time and then cool them to eliminate the quenching internal stress, reduce the brittleness of the material, adjust the balance between hardness and toughness, and make the product obtain good comprehensive mechanical properties.

Output: Blank pieces with good comprehensive mechanical properties after heat treatment, and the performance indicators such as hardness, strength and toughness meet the requirements of product design.

(4) Fine Processing

Grinding

External Circle Grinding: Use external circular grinding machine to perform grinding processing on the external circular surface of the blank pieces after heat treatment to further improve the size accuracy and surface finish of the external circle and make it meet the high-precision requirements of the finished product.

Plane Grinding: Use plane grinding machine to grind the plane of the blank pieces to ensure the flatness and surface roughness of the plane and meet the assembly and use requirements of the product.

Inner Hole Grinding: Use internal circular grinding machine to grind the inner hole of the blank pieces to accurately control the size accuracy and surface quality of the inner hole and ensure the assembly precision between the inner hole and other parts.

Output: Semi-finished products with very high size accuracy and surface quality after grinding processing, which basically meet the accuracy requirements of the finished product.

(5) Post-Processing and Packaging

Cleaning

Operation: Adopt appropriate cleaning technology (such as ultrasonic cleaning, chemical cleaning, etc.) to remove the oil stains, iron scraps, impurities and other residues on the surface of the semi-finished product during the processing to ensure the cleanliness of the product surface.

Output: Finished products with clean surface.

Inspection

Operation: According to the quality standards and inspection specifications of the product, conduct a comprehensive inspection on the finished products after cleaning, including the detection of size accuracy, shape error, surface quality, mechanical properties and other aspects to ensure that the product quality meets the requirements.

Output: The qualified finished products enter the next packaging link, and the unqualified products are reworked or scrapped according to the situation.

Packaging

Operation: According to the characteristics and transportation requirements of the product, select appropriate packaging materials (such as cardboard box, plastic bag, foam, etc.) to pack the finished products. Mark the relevant information (such as model, specification, quantity, etc.) of the product on the packaging to facilitate storage and transportation.

Output: Products that have been packaged and can be delivered to customers or stored in the warehouse.
