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.

Forgings refer to workpieces or blanks obtained by forging and deforming metal blanks. By applying pressure to a metal blank to cause plastic deformation, its mechanical properties can be changed. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room temperature, while hot forging is processed at a temperature higher than the recrystallization temperature of the metal blank.

General industrial forgings refer to civilian industries such as machine tool manufacturing, agricultural machinery, agricultural tool manufacturing, and bearing industry. Forgings for hydro-turbine generators, such as main shafts and intermediate shafts, etc.

Forgings used in thermal power stations, such as rotors, impellers, retaining ring spindles, etc. Metallurgical machinery, such as cold rolls, hot rolls and herringbone gear shafts, etc.

Forgings for pressure vessels, such as cylinders, kettle ring flanges and heads, etc. Marine forgings, such as crankshaft, tail shaft, rudder stock, thrust shaft and intermediate shaft, etc.

Forging machinery and equipment, such as hammer heads, hammer rods, columns and cylinders of hydraulic presses, pillars and cylinders of axle presses, etc. Modular forgings are mainly forging dies for hot die forging hammers.

Forgings are used in the automobile industry, such as left and right steering knuckles, front beams, couplers, etc. According to statistics, forgings account for 80% of the mass of automobiles. Forgings for locomotives, such as axles, wheels, leaf springs, locomotive crankshafts, etc. According to statistics, forgings account for 60% of the quality of locomotives. Forgings come in a wide range of weights. Forgings range from a few grams to hundreds of tons.

Forgings are of higher quality than castings. The mechanical properties of forgings are better than those of castings, and they can withstand large impact forces and other heavy loads. Therefore, forgings are used for some important parts that bear large forces.

For high carbide steels, forgings are of better quality than rolled products. For example, high-speed steel rolled products can only meet the usage requirements after being modified and forged. In particular, high-speed steel milling cutters must be modified and forged.

Forgings are lightweight. Under the premise of ensuring design strength, forgings are lighter than castings, which reduces the weight of the machine itself, which is of great significance to transportation vehicles, aircraft, vehicles and space aerospace equipment.

Forgings save raw materials. For example, for a crankshaft with a static weight of 17kg used in automobiles, when rolled material is used for cutting and forging, the chips account for 189% of the weight of the crankshaft, but when die forging is used, the chips account for only 30%, and the machining time is shortened by 1/6.

Precision forged forgings can not only save more raw materials, but also save more machining hours.

Forging productivity is high. For example, using two hot forging presses to forge radial thrust bearings can replace 30 automatic cutting machine tools. When using an upsetting automatic machine to produce M24 nuts, the productivity of a six-axis automatic lathe is 17.5 times higher.

News 3. How to choose a strong forging Brands?

Forging is a processing method that uses forging machinery to exert pressure on metal blanks. In fact, it is a processing method that causes plastic deformation to obtain forgings with certain mechanical properties, shapes and sizes. So do you know how to choose a powerful forging Brands?

When forging, what everyone must know is the deformation temperature. In fact, the initial recrystallization temperature of steel is about 727°C, but generally 800°C is used as the dividing line, and hot forging is higher than 800°C; forging performed at 300-800°C is called warm forging or semi-hot forging. Forging performed at room temperature is called cold forging. Therefore, forging Brandss believe that the forgings used in most industries are hot forgings. Warm forging and cold forging are mainly used for forgings such as automobiles and general machinery. Warm forging and cold forging can effectively save materials. People who choose this method can naturally improve the internal structure of forgings and improve mechanical properties. After forging, the structure and properties of the forging blank are improved and enhanced. Its processing can eliminate defects such as pores, shrinkage cavities and dendrites inside the metal ingot, and due to the plastic deformation and recrystallization of the metal, coarse grains can be refined to obtain a dense metal structure, thereby improving the mechanical properties of forgings. Forging Brandss believe that in part design, if the force direction and fiber structure of the part are correctly selected, the impact resistance of the part can be improved.

Today, there are many forging Brandss on the market. In this case, everyone must master certain methods when choosing. For example, choosing a strong forging Brands can guarantee the after-sales service and product quality of the product. During the production process, forging Brandss can ensure production quality from the production structure. So you have to look at strength. For many small and medium-sized investors, they lack certain market operation experience and skills and need to rely on the support and help of professional Brandss. Strength is mainly reflected in scale, production technology, product quality, after-sales service, etc. Comprehensive evaluation based on own information can make the comprehensive strength and support of forging Brandss clearer, allowing investors to devote more energy to operations. Now that this product can quickly become popular in the domestic market, it must have its own advantages and characteristics. For operators, if they do not understand the market, they need to understand the characteristics and advantages in order to conquer the market and customers.

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.
