Chinese utility model patent publication number CN203702896U discloses a kind of Die for pressing cap detected with inner ring chamfering, In specifically disclose two kinds of Die for pressing cap, one is the Die for pressing cap that guide post and the joint angle of base station are right angle, another kind is to be oriented to The junction of column and pedestal is equipped with intermediate incline, and the angle of the intermediate incline is identical with bearing inner race chamfering to be laminated Die for pressing cap, but either which kind of Die for pressing cap cause dustband to be pressed into due to lacking part compatible with the bending part of dustband When position inaccurate, will produce radial and axial position deviation, dustband caused to cannot achieve due sealing function.
Utility model content
When the technical problems to be solved in the utility model is existing bearing seal cover press mounting die pressing bearing sealing cover It can not be accurately positioned, generation position deviation, a kind of bearing seal cover press mounting die is provided thus.
The technical solution of the utility model is：Bearing seal cover press mounting die, it include gland mould core portion, pressing mold sleeve and Locating piece in pressing mold, the gland mould core portion includes pedestal, and guide part, the base bottom edge are connected at the top of the pedestal Frustum is extended downwardly, the gland sleeve is socketed on outside pedestal, and locating piece is affixed with base bottom in the pressing mold and keeps With one heart, locating piece includes locating core and the outer circular edge portion outside locating core in the pressing mold, and the outer circular edge portion reclines The conical surface on the inside of frustum and with frustum forms bending part, and the end face of the gland sleeve and the conical surface of frustum retain a spacing From.
The male cone (strobilus masculinus) cone angle of frustum described in said program is less than inner conical surface cone angle.
The male cone (strobilus masculinus) cone angle of frustum described in said program is 30 °, and inner conical surface cone angle is 45 °.
The improvement of said program is the shoulder that the pedestal has expansion diametrically with the region of guide part transition, described Shoulder is bonded with the end face of gland sleeve.
Locating core described in said program is concentric affixed with pedestal by bolt.
Pressing mold sleeve lateral wall described in said program is fixed by screw and pedestal.
The utility model has the beneficial effects that pressing mold sleeve, frustum and the cooperation of outer circular edge portion, in indentation bearing seal cover When be bonded with the bending part of bearing seal cover and in the accurate indentation sealing slot of bearing seal cover, will avoid generating axially and radially position Set deviation；Overall structure is simple, is readily disassembled maintenance, prolongs the service life.

Specific implementation mode
As shown in figure 3, the utility model includes gland mould core portion, locating piece in pressing mold sleeve and pressing mold, the Die for pressing cap Core includes pedestal 6, is connected with guide part 7 at the top of the pedestal, the base bottom edge has extended downwardly frustum 8, described Gland sleeve is socketed on outside pedestal, and locating piece is affixed with base bottom in the pressing mold and keeps concentric, positioning in the pressing mold Block includes locating core 9 and the outer circular edge portion 10 outside locating core, the outer circular edge portion stick on the inside of frustum and with cone The conical surface of platform forms bending part 11, and the end face of the gland sleeve and the conical surface of frustum retain certain distance.
The utility model is described further with reference to the accompanying drawings and embodiments.
The "inner" and "outside" mentioned in the utility model refer to relative to the bearing seal cover press mounting die assembled and Speech, such as inner conical surface refer to that the face coordinated with locating piece in pressing mold, male cone (strobilus masculinus) refer to the face with close pressing mold sleeve.
Embodiment 1：Bearing seal cover press mounting die, it includes gland mould core portion, locating piece in pressing mold sleeve and pressing mold, institute It includes pedestal 6 to state gland mould core portion, and guide part 7 is connected at the top of the pedestal, and the cylinder of the guide part and greasing gland machine connects It connects, the utility model is moved up and down by cylinder drive.The base bottom edge has extended downwardly frustum 8, which has outer The cone angle of the conical surface and inner conical surface, male cone (strobilus masculinus) is 30 °, and the cone angle of inner conical surface is 45 °, and the height of inner conical surface is 0.25mm, the pressure Lid sleeve is socketed on outside pedestal, and locating piece is affixed with base bottom in the pressing mold and keeps concentric, locating piece in the pressing mold Outer circular edge portion 10 including locating core 9 and outside locating core, locating core and outer circular edge portion are concentric, the outer circular edge portion It sticks on the inside of frustum and forms bending part 11, the certainly inner conical surface which refers to, the bending part and axis with the conical surface of frustum The bending part for holding sealing cover is bonded completely, and the end face of the gland sleeve and the conical surface of frustum retain certain distance, this is apart from root Size is determined according to bearing concrete model.
