Abstract
The utility model discloses a cold-heading die for processing a conical roller with extra large angles, which is mainly composed of a base (1), a casing (2) and a work sleeve (3), wherein the exterior of the casing (2) is provided with an installation notch (5), the work sleeve (3) is opposite to the base (1), and both of the installation notch (5) and the work sleeve (3) are respectively in interference fit with the casing (2); the work sleeve (3) is provided with a work cone concave bore (4) of which the coning angle is 14 DEG 50'. The utility model has reasonable structure, and the conical roller with extra large angles, which is in accordance with the requirement, can be manufactured by the existing machine tool equipment via the cold-heading die in the existing condition.
Description
Affiliated technical field
The utility model belongs to the bearing roller processing industry, relates generally to a kind of especially big angle (coning angle is more than 12 °) conical bearing roller that is used for and processes with cold pier die.
Background technology
Taper roller is one of a kind of major part in the taper roll bearing, the taper roller coning angle generally all adopts less than 8 ° of cone angles, its processing mode generally adopts the Z31-13 lathe cold-heading moulding that feeds intake, and drives self-feeding by helical wheel and finish mill processing on the M3180 lathe.This processing mode is very universal in the bearing roller processing industry, and from the cold-heading Mould design, to the mill processing of taper roller, under normal circumstances, processing is relatively easy, does not have too big difficulty.Especially big angle taper roller is meant that mainly coning angle is greater than 12 ° taper roller.This class roller is mainly used in the thrust roller bearing of full dress roller.No matter the processing of especially big angle taper roller is cold pier die molding procedure, still grinds manufacturing procedure, is a difficult point of roller processing industry always.
Summary of the invention
The purpose of this utility model provides a kind of especially big angle taper roller that is used for rational in infrastructure and processes with cold pier die.
The purpose of this utility model can adopt following technical problem to realize: it mainly is made of base, overcoat and work cover, overcoat outer setting one is installed otch, the work cover is relative with base, both respectively with the overcoat interference fit, work puts work circular cone shrinkage pool is set, and the coning angle of the round awl shrinkage pool of will working be arranged to 14 ° 50 '.
The utility model is rational in infrastructure, utilizes above-mentioned cold pier mould, can utilize existing machine tool equipment under existing condition, processes satisfactory especially big angle taper roller.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: 1, base, 2, overcoat, 3, the work cover, 4, work circular cone shrinkage pool, 5, otch is installed.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: the utility model mainly mainly is made of base 1, overcoat 2 and work cover 3 it, overcoat 2 outer setting one are installed otch 5, be used for fixing with lathe, work cover 3 is relative with base 1, both respectively with the overcoat interference fit, working to put is provided with work circular cone shrinkage pool 4, as working hole, be used to place charge bar, the semi-cone angle of circular cone shrinkage pool 4 be α be 7 ° 25 ', corresponding coning angle be 14 ° 50 '.
During work, itself and existing lathe cooperate, and change friction feeding into, the complete designing requirement of the super-huge type tapered roller that processes by single feeding.
Claims (1)
1, a kind ofly is used for the processing of especially big angle taper roller with cold pier die, it mainly is made of base (1), overcoat (2) and work cover (3), overcoat (2) outer setting one is installed otch (5), work cover (3) is relative with base (1), both respectively with overcoat (2) interference fit, work cover is provided with work circular cone shrinkage pool (4) on (3), it is characterized in that: the coning angle of work circular cone shrinkage pool (4) be 14 ° 50 '.
