Abstract
The invention discloses a high and low pressure separator forging process, which relates to the technical field of forging, and comprises the following steps: S1, raw material selection; S2, intermediate frequency furnace heating; S3, descaling; S4, graded forging; S5, groove milling operation ; S6, shot blasting operation; S7, detection operation; S8, immersion oil storage. The invention has the advantages of reducing the occurrence of damage to the convex surface during punching and helping to ensure the qualified rate of the high and low pressure partitions.
Description
technical field [0001] The invention relates to the technical field of forging, in particular to a high and low pressure separator forging process. Background technique [0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. [0003] Currently, there is a high and low pressure partition, see figure 2 , which includes a disc-shaped disc body 1, the middle part of the disc body 1 is recessed and formed with a groove 2, and the middle position of the groove bottom...
