Forgings process of Forgings

Pre-Forgings preparation includes raw material selection, calculation, feeding, heating, calculation of deformation force, selection of equipment, design mold. You should also choose the lubrication method and lubricant before Forgings.

It is widely used in Forgings materials, including steel and high temperature alloy of various brand names, aluminum, magnesium, titanium, copper and other non-ferrous metals. It has been processed into different sizes of bars and profiles, and has many kinds of ingot materials. In addition to a large number of domestic materials suitable for China's resources, there are materials from abroad. Most of the Forgingss have been included in national standards, and many are new materials for development, trial and promotion. As is known to all, Forgings the quality of the products are often closely related to the quality of raw materials, so the Forgings factory worker, must have the knowledge of the necessary materials, must be good at choosing the most suitable material according to the technical requirement.

The calculation material and the lower material are to improve the utilization rate of Forgings materials and realize one of the important links in the refinement of the blank. Too much material not only causes waste, but also aggravates the wear and energy consumption of the mold. It is expected that if there is no allowance, it will increase the difficulty of the process adjustment and increase the waste rate. Forgings In addition, the quality of the lower end face has an influence on the process and the quality of Forgings.

The purpose of heating is to Forgings reduce Forgings deformability and improve metal plasticity. But heating also brings a range of problems, such as oxidation, decarbonization, overheating and overheat. Accurate control of initial Forgings and final Forgings temperature has great influence on product organization and performance.

Flame furnace heating has the advantages of low cost and strong applicability, but the heating time is long and it is easy to produce oxidation and decarburization. The working conditions also need to be improved continuously. Induction heating has the advantages of rapid heating and low oxidation, but it has a poor adaptability to the product shape size and material change.

The forming of Forgingss is produced under the action of external forces, so the correct calculation of deformation force is the basis for selecting the equipment and the core of the mold. The analysis of stress strain within the variable form is also indispensable for optimizing the process and controlling the performance of the Forgingss.

There are four main methods for analyzing the deformation force. Although the principal stress method is not very strict, it is simple and intuitive to calculate the stress distribution of the total pressure and the contact surface of the Forgings and tools. The slip line method is strict to the plane strain problem, and the stress distribution of the high part deformation is more intuitive, but the application scope is narrower. The upper limit method can give an overestimated load, and the upper element can also predict the shape change of the Forgingss. The finite element method can not only give out the change of the load and Forgings shape, also can give the internal stress and strain distribution, the disadvantage is that computer machine is more, especially by elastic-plastic finite element solution, need computer capacity is bigger, a longer machine. Recently there has been a trend to combine methods to analyze problems, for example. The upper limit method is used to calculate the rough calculation.
