Abstract

The invention relates to an orging process of outer blank for double-row tapered roller bearings. The orging process is characterized by including the steps of A, upsetting bars; B, subjecting a press machine to extruding to form blind holes; C; performing punching to form through holes and regulating height; D, adopting a combined rolling wheel on a ring rolling machine to do a first ring rolling, and chamfer structures in double-inner taper forms are rolled; E, adopting the combined rolling wheel on a ring rolling machine to do a second ring rolling, double roller paths in the inner taper forms and size from outer-diameter to forging blank are rolled; F, forming. The orging process is reasonable in process, adopts extruding forming to acquire blanks before ring rolling and allows the blanks to be rolled and formed; forging blanks are equal to finished bearing outer rings in shapes, forging precision is high, turning margin is low, material utilization rate is high, following processing workload is reduced, and production cost is lowered.

Description

Double-row tapered roller bearing outer ring blank forging technique
Technical field
The present invention relates to a kind of production technology of bearing, especially relate to a kind of double-row tapered roller bearing outer ring blank forging technique.
Background technology
Double-row tapered roller bearing outer ring has two raceways of inner conical, free piercing rolling technique is adopted to be straight tube shape Forging by blank forging in existing process, concrete technological process is: jumping-up → rush blind hole → rush through hole → reaming → rolling, forging structure is straight cylindrical shape, and the shape and size in whole blank manufacture process control to rely on manual operations to control, and forging stock precision is poor, machining allowance is large, stock utilization is lower, and the workload of following process is large, and production cost is higher.
Summary of the invention
The applicant is for above-mentioned problem, be studied improvement, a kind of double-row tapered roller bearing outer ring blank forging technique is provided, technological process is reasonable, and forging blank shape is identical with the outer loop-shaped of bearing finished products, and forging stock precision is high, machining allowance is little, stock utilization is high, reduces the workload of following process, reduces production cost.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of double-row tapered roller bearing outer ring blank forging technique, comprises the following steps:
A, bar jumping-up;
The extruding of B, forcing press forms blind hole;
C, punching press form through hole, and finishing height;
D, on Ring Rolling Machine, adopt combined type roll milling wheel to carry out the 1st rolling, spreading goes out the chamfering structure of two inner conical;
E, on Ring Rolling Machine, adopt combined type roll milling wheel to carry out the 2nd rolling, spreading goes out two raceway of inner conical and external diameter to forging stock size;
F, shaping.
Technique effect of the present invention is:
A kind of double-row tapered roller bearing outer ring blank forging technique disclosed by the invention, technological process is reasonable, blank before adopting extrusion molding to obtain rolling, then the method for rolling forming, forging blank shape is identical with the outer loop-shaped of bearing finished products, and forging stock precision is high, machining allowance is little, stock utilization is high, reduces the workload of following process, reduces production cost.
Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
Technological process of the present invention comprises the following steps:
A, bar heating after on forcing press jumping-up;
The extruding of B, forcing press forms the cylinder with blind hole;
C, punching press form the annulus with through hole, and finishing height;
D, on Ring Rolling Machine, adopt combined type roll milling wheel to carry out the 1st rolling, spreading goes out the chamfering structure of two inner conical;
E, on Ring Rolling Machine, adopt combined type roll milling wheel to carry out the 2nd rolling, spreading goes out two raceway of inner conical and external diameter to forging stock size;
F, shaping, become the annular forging stock with the two raceway of inner conical.
Through the double-row tapered roller bearing outer ring blank of the extruding-rolling explained hereafter of above-mentioned steps, process stabilizing, production efficiency is high, forging stock precision is high, forging blank shape is identical with finished product double-row tapered roller bearing outer ring shape, and machining allowance is little, and stock utilization is high, reduce the workload of following process, reduce production cost.
