Why do die forgings fail?
The so-called forging die failure refers to the forging die can not be repaired to restore its use function of damage, that is, caused by the damage or scrap of the commonly said forging die. Because plays a forming die chamber of the function of the forgings, it directly in contact with the hot ...Read more -
What is the inspection procedure for forging products?
The inspection procedure of forged products is as follows: ① All forgings should be cleaned before acceptance of finished products. Free forgings may not be cleaned. ② Before the acceptance of finished products, the forgings submitted for inspection and acceptance should be checked against the ac...Read more -
What is the difference between hot forging and cold forging?
Hot forging is the forging of metal above the temperature of recrystallization. Increasing the temperature can improve the plasticity of the metal, is conducive to improving the internal quality of the workpiece, so that it is not easy to crack. High temperature can also reduce the metal deformat...Read more -
What are the characteristics of special steel?
Compared with ordinary steel, special steel has higher strength and toughness, physical properties, chemical properties, biocompatibility and process performance. But special steel has some different characteristics from ordinary steel. For ordinary steel many people are more understanding, but f...Read more -
What is the effect of thick rubbing on forging process?
Friction in forging is the friction between two metals of different composition and properties (alloys), between soft metal (workpiece) and hard metal (die). In the case of no lubrication, is the contact friction of two kinds of metal surface oxide film; Under the lubrication condition, the conta...Read more -
Detailed classification of commonly used flanges in China
1. According to the standard of mechanical industry, flange types are: plate type flat-welded flange, butt-welded flange, integral flange, butt-welded ring-plate type loose sleeve flange, flat-welded ring-plate type loose sleeve flange, flanged ring-plate type loose sleeve flange, flange cover. 2...Read more -
What kind of shaft forgings meet the requirements?
Axial forging is a kind of wide application of forgings, such as axial plus has good processability, m any porosity in practice, there is no other flaws, thus not only has good appearance, with fine, here is how to introduce you to conform to the requirements of axial forgings to be popular. Firs...Read more -
The sealing method of hydraulic cylinder forging
The reason why the hydraulic cylinder forgings need to be sealed is because of the existence of internal leakage and external leakage. When there is internal leakage and external leakage in the hydraulic cylinder, it will lead to the volume of the hydraulic cylinder's cavity and the efficiency wi...Read more -
What forging technology does the flange factory have?
Flange factory is a production enterprise producing flanges. Flanges are parts connected between pipes, which are used for the connection between pipe ends. It is also useful for the flange on the inlet and outlet of the equipment for the connection between two devices. The production technology ...Read more -
How to forge stainless steel forgings?
The precision of rough or stainless steel forgings is higher. The application of advanced technology and equipment can achieve little or no cutting. The metal materials used in forging should have good plasticity, so that under the action of external force, plastic deformation can be produced wit...Read more -
The sealing principle and characteristics of flange
Sealing of flat-welded flanges has always been a hot issue related to the production cost or economic benefit of enterprises. However, the main design disadvantage of flat-welded flanges is that they are not leakproof. This is a design flaw: the connection is dynamic, and periodic loads, such as ...Read more -
What should be noted in the examination of die forgings before heat treatment?
The inspection before solution heat treatment is a pre-inspection procedure to check the finished product's surface quality and dimensions according to the technical conditions, die forging drawing and process card after the forging forming process is finished. Specific inspection should pay atte...Read more
