Chemical milling method for stainless steel precise forging blades

Abstract

Provided is a chemical milling method for stainless steel precise forging blades. The chemical milling method for the stainless steel precise forging blades obtains the stainless steel finish forgingblades of surface quality and thickness which meet process requirements by measuring and grouping stainless steel blade forgings, repeatedly performing chemical milling and polishing on the stainlesssteel blade forgings, and removing allowance of the blades by controlling chemical milling time and temperature, realizes uniform allowance removal, can control thickness fluctuation of the blades within 0.05mm, improves size stability of the products, improves the surface quality of the blades, avoids the problem that unstable quality is caused when a mold is used for directly performing preciseforging to obtain the final size of the blades, and improves qualified rate of the products; and reduces processing difficulty for the stainless steel blades, reduces demands for skill of operating personnel, simplifies the operation process, reduces consumption of the precise forging mold, and reduces processing cost.

Description

technical field [0001] The invention belongs to the technical field of chemical milling methods, and in particular relates to a chemical milling method for precision forging stainless steel blades. Background technique [0002] Stainless steel precision forging blades are generally relatively thin, with a thickness of only about 0.3mm. At present, the size control of stainless steel blades at home and abroad mainly adopts the means of one-time precision forging in place. However, because the product is relatively thin, the actual temperature of the product forging drops relatively quickly during forging, and the wear of the die is relatively large (according to statistics, a set of quenching dies made of H13 material can barely process about 1,000 workpieces), and the size of the workpiece The fluctuation is particularly large (according to statistics, the forging thickness fluctuation of the stainless steel blade is about 0.15), which leads to poor surface quality of the p...

Problems solved by technology

However, because the product is relatively thin, the actual temperature of the product forging drops relatively quickly during forging, and the wear of the die is relatively large (according to statistics, a set of quenching dies made of H13 material can barely process about 1,000 workpieces), and the size of the workpiece The fluctuation is particularly large (according to statistics, the fluctuation of the forging thickness of the stainless steel blade is about 0.15), so the surface quality of the product is relatively poor

However, to ensure the dimensional stability of precision forging blades, a large number of experienced operators are required to follow cumbersome operating procedures, which requires a lot of manpower and energy, which greatly increases the processing cost.
