Common forging form: free forging

Forging refers to the processing method in which the metal is deformed by impact force or pressure between the upper and lower anvils or forging dies. It can be divided into two types: free forging and model forging.

Comparison of stainless steel and carbon steel flanges?

Low thermal conductivity, about 1/3 of carbon steel. In order to prevent corrosion between eyes due to heating of flange cover, the welding current should not be too large, about 20% less than that of carbon steel electrode, the arc should not be too long, the interlayer should be quickly cooled, and narrow weld bead is appropriate.

What are the causes of heat treatment deformation of forging dies?

According to the introduction of forging flaw detection, after the production and processing of forgings, quality inspection should be carried out, and the factory can only be delivered after passing the inspection. Forgings can be inspected in various ways such as surface state inspection and mechanical property inspection. Chemical composition analysis should also be carried out for important parts, key parts or large forgings.

What are the quality control methods of forging production and processing in Shanxi forging factory

Roller forgings are widely used, and the working conditions are complex and diverse. In addition to the conventional mechanical properties, various rolling mills put forward a series of special requirements for the performance of the roller, which are different from other forgings. The surface of the roller body has to withstand fatigue caused by friction, wear, impact, contact stress and chilling and heating for a long time. During the rolling process, the roller body has to withstand high stress, mainly bending stress and friction. The main drive roller also bears huge torque.

What are the common materials and properties of shaft forgings

Gear shaft manufacturer tips: the material of gear shaft forgings must first meet the requirements of working conditions. The requirements of working conditions are the first factors to be considered when selecting gear forging materials. Alloy steel is often used to make gear forgings that work under high speed, heavy load and impact load. For example, gears used in aircraft should meet the requirements of low quality, high transmission power and high reliability. Therefore, alloy steel with high mechanical properties must be selected. If the gear size is required to be as small as possible, high-strength alloy steel with surface hardening treatment should be adopted. The gear transmission in mining machinery, generally has high power, low working speed, and high dust content in the surrounding environment, so materials such as cast steel or cast iron are often selected. The power of household and office machinery is very small, but it requires smooth transmission, low noise or no noise, and can work normally under less lubrication or no lubrication. Therefore, engineering plastics are often used as gear materials.

Forging process and forging characteristics

Forgings by plastic deformation to shape the required shape or suitable compression force of the object. This is achieved by using a hammer or pressure. After forging, the structure and mechanical properties of the metal can be improved. The forging process can ensure the continuity of the metal fiber structure, make the fiber structure of the forging consistent with the shape of the forging, and the metal streamline is complete, which can ensure that the parts have good mechanical properties and Long service life.
