Pressure flange forging process, the main purpose is to obtain size

Pressure flange forging process, the main purpose is to gain size , shape drawing in full compliance with the requirements of a qualified wrought products . Hydraulic flanges forming two basic conditions, one during the deformation process can withstand the hydraulic flange round the amount of deformation required to not destroy the external structure , and second power condition that part of the equipment through a die to apply sufficient and the particular distribution of the force . Through hydraulic ferrulethe efforts of manufacturing conditions , optimizing the production process , the production of qualified workers forging wrought products is an important task . Hydraulic forging process selection is flexible flange , the flange forming a hydraulic step , the same kind of forged parts can be produced hydraulic tube fittingby different devices or different production method to complete. For example if the link on forging hammer smithy , the rough material in the same mold chamber to complete pre-forging , the final forging , stretching , rolling . Should the pressure of hydraulic forging machine , you need to use the pre- rolled forging blank . If you are using forming roll forging methods to produce , you can then add a precision roll forging shaping step and get qualified hydraulic flanges. Another example is the multi-station cold forging step shaft , forged for the same product can have different processing techniques , the use of different hydraulic flange blank , the corresponding intermediate steps are not the same , and some contain forward extrusion , some with side squeeze . The deformation stress required size is different , the service life of the mold is also a great difference .
