Abstract

The invention provides a machining technology of a cam-mould special-shaped concave-mould. The machining technology sequentially comprises the following processes of material sawing, rough turning, special shape rough milling of a machining center, heat treatment, numerical-control finish turning, plane abrasion, pressure distribution, special shape finish milling of the machining center, grinding, pressure withdrawing, S-N co-diffusion, polishing and secondary pressure distribution. According to the machining technology of the cam-mould special-shaped concave-mould, the profile tolerance of the concave-mould after the follow-up special shape finish milling of the machining center is guaranteed through the pressure distribution process in the concave-mould machining technology, so that the profile tolerance of the concave-mould is ensured to be within 0.02 mm, therefore the profile tolerance of a cam forge piece is guaranteed, further the product profile tolerance after the follow-up heat treatment is conducted is ensured, and the production quality is improved.

Description

technical field [0001] The invention relates to the field of die processing, in particular to a processing technology for a special-shaped concave die of a cam die. Background technique [0002] At present, the common processing technology of cam special-shaped die is: sawing material → rough turning → heat treatment → CNC finishing → flat grinding → machining center milling special shape → grinding → S-N co-infiltration → polishing → pressure matching. The disadvantage of this process is that the contour of the special-shaped die cannot be guaranteed in the whole process, and the deformation amount is different when the cam is closed and hot forged. In the process, the product profile is not guaranteed. Contents of the invention [0003] In order to solve the above-mentioned technical problems, a kind of processing technology of the special-shaped die of cam die that the present invention proposes, its specific technical scheme is as follows: [0004] A processing techn...
