Abstract

The invention relates to a servo direct-drive type incremental rolling forming process for a cylindrical piece with teeth inside and outside. The process comprises the following steps: sleeving the blank of the cylindrical piece on a core mold; axially feeding to a high-frequency induction heater under driving of a composite alternating current servo motor and heating quickly; continuously and axially feeding to the rolling position of 3 to 6 rolling molds which are circumferentially and uniformly distributed along the axis of the blank, wherein the rolling molds are driven by an adjusting alternating current servo motor to radially feed and driven by a main power alternating servo motor, and the blank and the core mold are driven by the composite alternating current servo motor simultaneously; gradually finishing incremental rolling forming of the cylindrical piece with teeth inside and outside under the action of the rolling molds; withdrawing the blank reversely; and unloading. The process has the advantages of simple process system, high control precision, small forming force, high forming quality, wide processing range and the like.

Description

technical field [0001] The invention belongs to the field of advanced metal plastic processing and numerical control forming equipment, and specifically relates to a servo direct-drive incremental rolling forming process for inner and outer toothed cylindrical parts. Background technique [0002] The inner and outer toothed cylindrical parts mainly include clutch housing, sliding sleeve, meshing tooth shape of transmission wheel and inner teeth of planetary gear, etc., which are usually used in automobiles, ships, aerospace and other fields. With the development of modern manufacturing industry, higher requirements are put forward for the production process and performance of parts. [0003] The existing processing technology of internal and external geared cylindrical parts mainly includes traditional cutting processing, extrusion and spinning forming processing. Among them, cutting processing is mainly gear shaping processing, but the process is complicated and the proces...
