Automotive stamping parts

metal stamping parts that constitute automotive parts.

Car internal stamping parts. In automotive parts, some parts can be used directly after stamping.
Appearance and structure stamping parts. The other part after stamping also need to go through welding, or mechanical processing, or paint and other processes to become a part of the car.

The classification of automotive stamping parts and body structure:

  1. Overall side circumference (left, right)
  2. Wing plate (left, right)
  3. Outer plate of machine cover
  4. Inner board of the machine cover
  5. Trunk board
  6. Inner board of luggage
  7. Front door panel (left, right)
  8. Front door inner board (left, right)
  9. Rear door panel (left, right)
  10. Back door inner board (left, right)
  11. the top
  1. Engine compartment assembly
  2. Baggage compartment assembly
  3. Side inner plate assembly
  4. Floor assembly
  1. Medium reinforcing board
  2. Small reinforcing board
  3. Small scaffolds
  4. Floor
  5. Strengthen beams
  6. Inner and outer plate of wheel cover
  7. Front assembly
  8. Suspension assembly
  9. Fuel tank cover assembly

In medium and heavy vehicles, most of the covering parts, such as the body outer plate, and some load-bearing and supporting parts, such as the frame, carriage and other auto parts are stamping parts.

Material selection for automotive stamping parts

Automotive parts production using a large number of cold stamping process.
Used in cold stamping steel plate and steel belt is the main steel, account for 72.6% of the vehicle steel consumption of cold stamping material close relation with auto stamping parts production.

The stand or fall of material not only decides the performance of the product, more directly affect the product quality, cost, service life, and the rationality of the design of the production and the difficulty, so reasonable choice material is an important and complex work.

Selection principles of materials:

  • Can meet the performance requirements of auto parts.
  • Good physical and chemical properties of materials.
  • Better economy.

Chapter 1:


Automobile stamping defect and quality control

Understand the automobile stamping

By applying external force to plate, pipe and profile by press and mold, the material can produce plastic deformation or separation, so as to obtain the designed shape and size.

Plastic processing (or pressure processing) is divided into stamping and forging.

Structural reinforcement for car

Automotive stamping parts according to the quality grade, divided into:

  • Exterior parts.
    Fine stamping parts requiring coating or polishing and painting
  • Internal parts.
    Internal structural parts are the main, not directly exposed to the air. The main requirement is high performance stamping parts

Quality control of automobile stamping

“3S inspection” of automobile stamping parts:

  1. Self-inspection
    In the process of production, the operator himself completes the quality inspection of the products in this process
  2. Substitute inspection
    The operator checks the finished quality of the product from the previous process, and whether it meets the processing quality requirements of his own process
  3. Special inspection
    Full-time inspectors check whether the quality of materials meets the processing requirements, and at the same time check the quality characteristics of any process in the whole process

Common defects in automobile stamping

Common defects
Automotive stamping parts’ defect level

Level.A

A defect 1

A defect 1

A defect 2

A defect 2

1. Defective parts that can’t be accepted by customers, whose shape or size exceed the tolerance range. Finally scrap the parts.

2. Judge:

  • Internal injury. Visually, the material becomes thinner, less than 70% of the material thickness. Usually, the old staff can easily judge the material thickness according to their experience.
  • Cracking. Visually, a cracking point or fault zone is found.

3. Cause
Internal injury is common in R Angle, due to stretch denaturation and thinning, resulting in internal injury. In severe cases, cracking occurs. Hidden damage and cracking will reduce the strength of the stamping parts.

4. Preventive measures
Maintain mould regularly, keep mould and product clean and lubricate.

Level.B

B defect 1

B defect 1

B defect 2

B defect 2

1. A surface defect that can be seen or felt. Need rework.

2. Cause

  • Material
    Plate or mold surface dirty, after blanking burr, etc.
  • Equipment
    The suction cup of the servo machine is dirty and the table of the press machine is sundry.

3. Preventive measures
Keep clean

Level.C

C defect 1

C defect 1

C defect 2

C defect 2

1. Can not directly see, but by the method such as oil stone can found the surface concave and convex point or burr. Should better be corrected.

2. Judge
Apply oil or oil stone to determine the severity of surface defects. Hemp point ≤5, burr ≤1.5mm.

3. Cause

  • Material in processing is not clean
  • The production environment is dusty and sandy
  • Mold tool edge wear

4. Preventive measures

  • Strengthen mold and material cleaning and maintenance work, record and analyze the problems
  • Inspect and clean equipment before use
  • You can create a closed job environment
  • Maintain tool edge according to frequency
