The existence of forging defects, some will affect the processing quality or processing quality of subsequent processes, and some will seriously affect the performance and use of forgings, or even greatly reduce the service life of the finished parts and endanger safety. Therefore, in order to ensure or improve the quality of forgings, in addition to strengthening quality control in the process and taking corresponding measures to prevent the occurrence of forging defects, necessary quality inspections should also be carried out to prevent problems with subsequent processes (such as heat treatment, surface treatment, cold working) Forgings with defects that have a negative impact on performance will flow into subsequent processes. After quality inspection, remedial measures can also be taken on the finished forgings according to the nature of the defects and the extent of their impact on use, so that they meet technical standards or usage requirements. Therefore, in a sense, forging quality inspection is, on the one hand, to check the quality of the produced forgings, and on the other hand, it is to point out the direction for improvement of the forging process, thereby ensuring that the quality of forgings meets the requirements of forging technical standards and meets the design, Processing and use requirements.

The inspection of forging quality includes inspection of appearance quality and internal quality. The appearance quality inspection mainly refers to the inspection of the geometric dimensions, shape, surface condition and other items of the forgings; the internal quality inspection mainly refers to the inspection of the chemical composition, macrostructure, microstructure and mechanical properties of the forgings. Specifically, the appearance quality inspection of forgings is to check whether the shape and geometric dimensions of forgings comply with the requirements of the drawing, whether there are defects on the surface of forgings, what nature the defects are, and what their morphological characteristics are. The inspection content of the surface condition is generally to check whether there are surface cracks, folds, wrinkles, pits, orange peels, blisters, scars, corrosion pits, bruises, foreign objects, underfill, pits, lack of flesh, etc. Scratches and other defects.

The internal quality inspection is to check the inherent quality of the forging itself, which is a quality condition that cannot be discovered by the appearance quality inspection. It includes not only checking the internal defects of the forging, but also checking the mechanical properties of the forging, and for important parts and key parts. Parts or large forgings should also undergo chemical composition analysis. For internal defects, we will use low-magnification inspection, fracture inspection, and high-magnification inspection to check whether the forgings have internal cracks, shrinkage cavities, looseness, coarse grains, white spots, dendrites, streamlines that do not conform to the shape, Defects such as turbulent streamlines, cross-flow, coarse crystal rings, oxide films, delamination, overheating, and overburned structures. As for the mechanical properties, it mainly checks the normal temperature tensile strength, plasticity, toughness, hardness, fatigue strength, high temperature instantaneous fracture strength, high temperature lasting strength, lasting plasticity and high temperature creep strength, etc.

Since forgings are made into parts, their stress, importance, and working conditions are different during use, and the materials and metallurgical processes used are also different. Therefore, different departments divide forgings into categories based on the above conditions and in accordance with the requirements of the department. , different departments and different standards classify forgings differently.

What are the advantages of forging factory processing? I believe many friends are still unclear about it. In order to enhance everyone’s understanding, the editor below will introduce this issue in detail. If you are interested, let’s take a look! If you are also interested, you may wish to come here. Check it out.

Forging is also a popular product now. But many people still don’t understand its function. The first thing we need to know is that the advantage of forging Brandss is high material utilization. Plastic forming of metal is mainly about rearranging the relative positions of metal structures without removing metal. And have higher productivity. In addition, forging Brandss usually use presses and forging hammers. Blanks or forgings are more accurate. Brandss have also applied advanced technology and equipment here to achieve less or no cutting. The metal material used should have good plasticity, so that it can produce plastic deformation without breaking under the action of external force. Among commonly used metal materials, cast iron is a brittle material with poor plasticity and cannot be used for forging. Copper, aluminum and their alloys in steel and non-ferrous metals can be processed in cold or hot conditions. The materials used by forging Brandss are mainly carbon steel and alloy steel of various compositions.

Followed by aluminum, magnesium, copper, titanium and their alloys. The original state of materials is bar stock, steel ingot, metal powder and liquid metal. This is because the ratio of the cross-sectional area of the metal before deformation to the cross-sectional area after deformation is called the forging ratio. In addition, the advantage of forging factory processing is that less material can be used to achieve the required strength, which helps reduce weight. Forging Brandss use forging machinery to apply pressure to metal blanks to cause plastic deformation in order to obtain forgings with certain mechanical properties, shapes and sizes. It is one of the two major components of forging and stamping. Parts with complex shapes can be produced, especially blanks with complex inner cavities. In particular, it has wide adaptability and can cast metal materials commonly used in the industry, ranging from a few grams to hundreds of tons. Moreover, its raw materials are widely sourced and cheap, such as scrap steel, scrap parts, chips, etc. The shape and size are very close to the parts, which reduces the cutting amount and is a non-cutting process. Another big advantage is that it is widely used. 40% to 70% of the weight of agricultural machinery and 70% to 80% of the weight of machine tools are castings. The products of forging Brandss mainly serve rail transit system parts, high-speed locomotive parts, and heavy-duty truck parts.

High-speed cutting technology for automotive stamping dies is of great benefit to save production time and improve production efficiency, but generally high-speed cutting requires milling speed greater than 40,000 revolutions per minute. All parts of the high speed lathe must be matched to make the machine work properly. What are the specific requirements for automobile stamping die production?

Because the high-speed cutting lathe is controlled by microcomputer program, it is necessary to have a central processing unit (CPU) and large-capacity storage equipment which can process large amounts of data quickly; have a faster data transmission capacity and network transmission capacity; have error compensation functions, including measurement error compensation, quadrant error compensation, thermal error compensation.

The drive system requires a large feed speed and acceleration, generally 20-30 meters per minute and 20-40 meters per second square.

Main shaft of high-speed airport. Because the stamping die in high-speed cutting to milling speed is very fast, so the speed of the spindle should also keep up with the general need to adjust between 10,000 to 100,000 per minute, with rapid speed-up and rapid precision stop performance. Therefore, the bearing structure of lathe generally adopts hydrostatic pressure, aerostatic and suspension magnetic levitation.

The machining of automobile stamping dies is carried out by milling cutters. Milling with tens of thousands of rotations tests the hardness and wear resistance of the cutters. Therefore, for cutting tool materials, cemented carbide and polycrystalline diamond must be used. At the same time, tool positioning must be precise and error controlled within 0.001mm.

Automotive stamping parts refer to parts processed by stamping technology during the production of auto parts. Their quality is crucial to the safety and reliability of the entire vehicle. In order to ensure that the quality of automotive stamping parts meets the requirements, a series of quality inspection standards have been formulated. The following are some common requirements for automotive stamping parts quality inspection standards.

1. Appearance quality

The appearance quality of automotive stamping parts is a very intuitive inspection item, which mainly includes the surface finish, concave and convex, scratches, oxidation and rust of the parts. The standard of appearance quality is usually agreed upon by the Brands and the customer, and samples or pictures are generally used as the standard, with specific descriptions of allowable defects.

2. Dimensional accuracy

Automotive stamping parts require high dimensional accuracy, and measuring tools are usually used for measurement. Common dimensional accuracy standards include tolerance range, average deviation, absolute value of deviation and ratio of absolute value of deviation, etc. The dimensional accuracy standards of different parts will vary according to actual usage and technical requirements.

3. Material quality

The material quality of automotive stamping parts is an important factor in ensuring their performance. The testing of material quality includes material type, chemical composition, physical properties and heat treatment. Common detection methods include spectral analysis, tensile testing, hardness testing and metallographic analysis.

4. Durability

Automotive stamping parts need to withstand long-term reciprocating motion and loading, so durability is one of its key indicators. Durability testing usually uses a test bench to conduct simulation tests to evaluate the service life and failure probability of parts under actual use conditions.

5. Welding quality

For some automotive stamping parts, welding is one of the processes necessary to complete their assembly. The detection of welding quality mainly includes the shape of the weld, the welding strength and the fusion of the welding materials. The standard of welding quality is usually determined based on the welding process regulations and relevant welding standards.

6. Surface treatment quality

In order to protect the surface of automotive stamping parts from corrosion and damage and improve its decorative effect, surface treatments such as galvanizing, spraying and coating are usually required. The detection of surface treatment quality mainly includes indicators such as film thickness, adhesion and anti-corrosion performance.

7. Precision

Some automotive stamping parts require high precision to ensure the accuracy of their fit and movement. Precision testing is usually performed using a three-dimensional coordinate measuring instrument or special testing equipment to evaluate the accuracy of parts such as size and shape.

8. Performance testing

Corresponding performance tests are required according to different types of stamping parts. For example, stamped parts for automobile chassis need to pass performance tests such as dynamic strength and stiffness, while automobile exterior parts pay more attention to corrosion resistance and wear resistance.

9. Environmental adaptability

Automotive stamping parts need to have certain environmental adaptability, that is, they can still work normally and maintain a certain service life under different climate conditions and working environments. Common environmental adaptability test items include high temperature test, low temperature test, damp heat test and salt spray test.

The above are some common quality inspection standards for automotive stamping parts. The specific requirements will vary according to the type of parts, use and relevant technical standards. In order to ensure the quality of automotive stamping parts, Brandss need to strictly conduct quality inspections in accordance with relevant standards to ensure that the products are qualified and meet the requirements, so as to achieve the goal of improving the quality and safety of the entire vehicle.
