Abstract

The invention relates to a method for forging and producing a gear ring. The method for forging and producing a gear ring comprises the following steps: blanking, heating, upsetting, punching and chambering, rolling rings, and annealing procedures; in the heating procedure, the tapping temperature of ingredients is 1050-1150 DEG C; in the upsetting process, the free forging temperature of a work piece is 1050-1150 DEG C; in the punching and chambering process, a taper end of a punch at the right center position hammers an empty upsetting rough model until 6-10 mm of a blind hole, and then a chamfering punch is applied to chamfer the original aperture; in the process of rolling ring, a chamfered blank is rapidly put in a mandrel of a ring roller for rolling ring; during the annealing procedure, the temperature is risen to 870 DEG C and kept for 1 hour; and then the temperature is reduced to 450 DEG C and kept for 3 hours; then the blank is discharged and cooled in the air. The method for forging and producing the gear ring is reasonable in technical route design, and capable of guaranteeing the technical requirement of processing the tooth ring; the method is short in production cycle, few in power consumption and low in cost.

Description

A kind of gear ring forging method
Technical field
The present invention relates to metal parts processing processing technology field, be specifically related to a kind of gear ring forging method.
Background technology
Along with the development of China's heavy industry level, the application of gear ring is also more and more extensive.At present, also there is a lot of problem in the forging method of gear ring, and process step design is unreasonable, manufacturing parameter is set with problem, and cause production efficiency in gear ring forging process low, gear ring product quality is not good enough, cannot reach technical requirement.
Summary of the invention
For solving the above-mentioned problems in the prior art, the invention provides a kind of gear ring forging method.
Technique effect of the present invention is achieved through the following technical solutions:
A kind of gear ring forging method, comprise blanking, heating, jumping-up, punching reaming, roll over ring, normalizing process, in heating process, batching tapping temperature 1050-1150 DEG C, in jumping-up operation, workpiece flat-die forging temperature is 1050-1150 DEG C, in punching reaming operation, centering center punching punching pin tapering end goes hammer down roughcast carries out hammering at sky, and hammering, to blind hole 6-10mm, expands just aperture with reaming punching pin; In rolling ring operation, stock good for reaming is put on the mandrel of Ring Rolling Machine fast, carries out rolling ring, at normalizing process, temperature is risen to 870 DEG C and keep 1 hour, cool the temperature to 450 DEG C subsequently and keep 3 hours, air cooling of coming out of the stove.
The invention has the beneficial effects as follows:
A kind of gear ring forging method disclosed in this invention, Process Route Planning is reasonable, and can ensure the technological requirement of processing gear ring, with short production cycle, power consumption is few, and cost is low.
Detailed description of the invention
A kind of gear ring forging method, comprise blanking, heating, jumping-up, punching reaming, roll over ring, normalizing process, in heating process, batching tapping temperature 1050-1150 DEG C, in jumping-up operation, workpiece flat-die forging temperature is 1050-1150 DEG C, in punching reaming operation, centering center punching punching pin tapering end goes hammer down roughcast carries out hammering at sky, and hammering, to blind hole 6-10mm, expands just aperture with reaming punching pin; In rolling ring operation, stock good for reaming is put on the mandrel of Ring Rolling Machine fast, carries out rolling ring, at normalizing process, temperature is risen to 870 DEG C and keep 1 hour, cool the temperature to 450 DEG C subsequently and keep 3 hours, air cooling of coming out of the stove.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
