Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0018] see figure 2 , an embodiment provided by the present invention: a novel flange processing and forming process, comprising the following steps:
[0019] S1: Select high-quality steel billets for blanking and heating;
[0020] S2: Take out the heated billet and place it on the processing and forming table;
[0021] S3: Move the special final forging die fixed with a hydraulic press-fitting device to the top of the billet, and use the pressure of the hydraulic press-fitting device to make the special final forging die perform final forging on the billet;
[0022] The die forging process that is very common now is to manually take out the steel billet through t...

The invention discloses a novel processing and forming process for flange parts, which relates to the related field of flange forming, in order to solve the problem of cracks in the flange caused by the strong vibration of the metal during the die forging process in the prior art. It includes the following steps: S1: select high-quality steel billets for cutting and heating; S2: take out the heated billets and place them on the processing and forming workbench; S3: move the special final forging die fixed with a hydraulic press-fitting equipment to the Right above the billet, the special final forging die is used for final forging of the billet by the pressure of the hydraulic pressing equipment; S4: After the final forging, the special final forging die and the hydraulic pressing equipment move forward together, so that the special final forging die and the hydraulic pressing equipment move forward together. A cutting die fixed by a hydraulic press-fitting equipment moves to the top of the billet, and presses down for punching and trimming.
Description
technical field [0001] The invention relates to the related fields of flange forming, in particular to a novel flange processing and forming process. Background technique [0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. [0003] The production process is mainly divided into forging, casting, cutting, and rolling. Different production processes are selected according to the requirements for the use of the flange. Among them, the quality of the forged flange is better, and it is generally produced by die forging. The crystal structure Fine and dense, high strength, more common in precision machinery; forged flanges are formed by pre-forging and final forging of heated blanks, then punching and trimming, but t...
