Forging process of hydraulic flange

The forging process of hydraulic flanges generally consists of the following procedures. First, select suitable steel materials for blanking, then heat and form them, and then forge and cool. Forging processing methods include die forging and free forging. During processing, different processing methods should be selected according to the size of the hydraulic flange product and the number of products produced. The free forging of hydraulic flanges has a large machining allowance and takes a long time to process, which is time-consuming and labor-intensive. The energy efficiency is low, but the production tools are simple, flexible and versatile, so it is used by ordinary factories for small batch production of products with relatively single forging shapes. The equipment for free forging of hydraulic flanges includes electro-hydraulic hammers, forging hydraulic presses and impact hammers, etc., which are especially suitable for processing large, medium and small products. Hydraulic flange die forging products have high processing efficiency, low processing cost, small processing allowance, convenient and simple operation, and easy to complete automated and mechanized production. Hydraulic flange die forging products have high dimensional accuracy and very small machining allowance, which will save a lot of cost. The structure and distribution of the product are more uniform and reasonable, with high density and high strength, thereby improving the quality and service life of the product.The metal plasticity of the hydraulic flange is an important characteristic of it, and various high-quality products can be manufactured by using its metal plasticity. Usually, die forging, stamping, cold drawing, extrusion, rolling and other production processes will cause a lot of deformation of metal products. Of course, in the various high-speed cutting production processes of drilling, turning and milling, all metal products will be deformed. The deformation can not only obtain a certain size and shape of the hydraulic flange, but also can change the internal structure and metallographic structure of the metal product, which can greatly improve the quality performance and metallographic structure of the product. Therefore, the development of metal deformation process and internal metallographic changes and their principles, familiar with the mechanical properties of products after deformation and the change of metallographic structure, and the structural changes of product deformed metals at high temperatures, will improve the manufacturing method of product materials, Improving the quality of hydraulic flanges and the proper use of materials are of great significance.
