Forged Pipe Fitting semifinished Various specifications can be customized


Forging forging the forging weight


1. Forging allowance: forgings precision and surface quality are poor, so the parts in the forging surface are left


forging margin to ensure that the parts can have a reasonable margin for mechanical processing, while Forging in


the forging due to the structure of parts and forging process, you must simplify the shape of forging, thereby


increasing the part of the dressing metal.


2. Burning weight: Forging billet In the process of heating and forging, the surface oxidation and burning part of the


weight of the metal, the first heat to take the metal weight of 2 to 3%, after each heating to take the metal weight of


1.5 to 2% , Stainless steel, alloy steel due to more alloying elements, plasticity decreased, deformation resistance


increases, the number of heating more, burning will be greater.


3. The weight of the part of the metal that is washed away or cut off for forging. Such as the middle of the opening


of the cover plate or tube plate in the forging of the middle of the material washed away, repair the end of the


forging of the material head, for large forgings must be used to cast steel ingot for the blank, but also consider the


cut off the steel cap Mouth and tail metal .


The precision forging process has been applied to the production of precision forging a lot of technology.


According to the different forming temperature can be divided into hot forging, cold forging, precision precision forging, composite precision forging, isothermal precision forging and so on.


1.1 Hot forging process forging temperature in the recrystallization temperature above the precision forging

process known as hot forging. Hot precision forging material deformation resistance is low, good plasticity, easy

to shape more complex parts, but due to strong oxidation, the workpiece surface quality and dimensional accuracy is low. Hot forging for the commonly used method for the closed die forging.


1.2 Cold forging process cold forging is carried out at room temperature forging process. Cold forging process has the following characteristics: the workpiece shape and size easier to control, to avoid the high temperature error; workpiece strength and high precision, good surface quality. Cold forging forming process towel, poor plastic parts, deformation resistance, the requirements of the mold and equipment, and difficult to shape the complex parts of the structure.


1.3 Temperature forging process temperature precision forging in the recrystallization temperature below a suitable temperature for the precision forging process. Warm forging precision forming technology not only break through the cold forging deformation resistance, the shape of the parts can not be too complicated, need to increase the intermediate heat treatment and surface treatment steps of the limitations, but also to overcome the hot forging due to strong oxidation and reduce the surface quality and size Accuracy of the problem. It also has the advantages of cold forging and hot forging, to overcome the shortcomings of the two.


1.4 Composite precision forging process With the increasingly sophisticated forging parts and precision requirements to improve the simple cold, warm, hot forging process has been unable to meet the requirements. Composite precision forging process will be cold, overflow, hot forging process to complete a workpiece forging, can play a cold, warm, hot forging the advantages of abandoning the cold, warm, hot forging shortcomings.


1.5 Isothermal forging process isothermal forging is the billet in the trend towards a constant temperature forging forming. Isothermal die forging is often used in the aerospace industry in the titanium alloy, aluminum alloy, magnesium alloy and other difficult deformation of precision forming materials, in recent years also used in automotive and machinery industry, non-ferrous metal precision forming. Isothermal forging is mainly used in forging temperature narrow metal materials, especially for the deformation temperature is very sensitive to titanium alloy.
