Hydraulic Flange

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 the 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 by 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 tube fittingsflange 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 diffe Preparatory work before forging steel including the original choice of materials and count, cutting, preheating, deformation stress calculation, select production equipment, tooling design. Before forging also need to choose a good quality lubricant and lubrication method.Hydraulic pipe fittingsflange forging material involves a wide variety of grades of both round and high-temperature alloy steel; established after a processed into bars of different sizes and shapes, there are a variety of specifications ingot; besides extensive use of a suitable material of the outer circle of domestic resources, but also from foreign steel. Most of the forging material has been included in the national standard library, there are many is to develop, trial and promotion of new material. As we all know, hydraulic flange quality is often closely associated with the quality of raw materials, so the forging worker, must have the necessary knowledge of raw materials, production process according to claim to be good at selecting the most suitable material.
