Description
Technical field
The invention belongs to a kind of manufacturing process area of shaft coupling, and in particular to a kind of manufacture craft of shaft coupling.
Background technology
Shaft coupling belongs to mechanical spare part in common use category, for connecting (the driving shaft and driven of two axles in different institutions
Axle) common rotation is allowed to transmit the machine components of moment of torsion, it is the part commonly used in mechanical industry, demand is big, more using forging
Make and blank is made, be then processed.Due to its special construction, the traditional forging technology made can not meet portioned product
It is produced, so production is low with forging efficiency, service life is low.
The content of the invention
(1) technical problems to be solved
The technical problem to be solved in the present invention is to propose a kind of manufacture craft of shaft coupling, to solve to use in conventional art
The problem of life-span is low.
(2) technical scheme
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of manufacture craft of shaft coupling, including
Following steps：
A, steel ingot is put into heating-up temperature in smelting furnace and, to 1120 DEG C, pressing tongs handle material, gnaws bottom, chamfered edge；
B, walk the blank material obtained to a to be heated again, be heated to 1200~1250 DEG C, jumping-up, pulling, expect cogging to the greatest extent,
First time forging ratio is controlled 2.0~2.5；
C, walk the blank material obtained to b to be heated again, be heated to 1100~1150 DEG C, jumping-up, pulling, flat end face with
Printed by figure number；
D, walk the blank material obtained to c to be heated again, be heated to 1000~1050 DEG C, put jumping-up in mould circle and be molded rear end
Gear blank flange end；
E, walk the blank material obtained to d to be heated again, be heated to 950~1000 DEG C, use core
Rod pulls out small shaft end to process, total forging ratio >=5 in shaft end, finishing and alignment；
F, the semi-finished product that e steps obtain are installed in machining center and be processed, first process the profile of semi-finished product, Ran Houzai
It is processed endoporus；
F is walked to the semi-finished product obtained to be heat-treated g, antirust oil is coated and is sealed up for safekeeping.
(3) beneficial effect
A kind of manufacture craft of shaft coupling of the present invention, forging precision is high, production efficiency easy to operate is high so that shaft coupling connects
It is higher to connect the precision of main shaft and driven shaft, reduces localized contact stress, extends service life.

Rod pulls out small shaft end to process, total forging ratio >=5 in shaft end, finishing and alignment；
F, the semi-finished product that e steps obtain are installed in machining center and be processed, first process the profile of semi-finished product, Ran Houzai
It is processed endoporus；
F is walked to the semi-finished product obtained to be heat-treated g, antirust oil is coated and is sealed up for safekeeping.
A kind of manufacture craft of shaft coupling of the present invention, forging precision is high, production efficiency easy to operate is high so that shaft coupling connects
It is higher to connect the precision of main shaft and driven shaft, reduces localized contact stress, extends service life.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
