Punching sealing device for composite sealed bearing

Abstract

The invention discloses a punching sealing device for a composite sealed bearing, and belongs to the technical field of bearing manufacturing. The punching sealing device for the composite sealed bearing is characterized in that a punching device (3) comprises a conical punching head (6) with certain conical degree at the lower end; a sliding sleeve (7) is sleeved outside the sliding part at the upper end of the conical punching head (6); an elastic punching claw head (13) which can swell around when being extruded by the conical punching head (6) is sleeved outside the punching head part at the lower end of the conical punching head (6); the upper end of the elastic punching claw head (13) is connected with the lower end of the sliding sleeve (7); a plurality of claw heads capable of punching a steel-made dustproof cover (10) inside a bearing (9) to be punched are uniformly distributed at the circumference at the lower end of the elastic punching claw head (13); and a support sleeve (8) which can be supported at the outer circle of the bearing (9) to be assembled is sleeved at the outer circle of the elastic punching claw head (13). The punching sealing device for the composite sealed bearing can being used for punching and sealing the composite sealed bearing, is high in efficiency, has improvement on production automation, and is safe and reliable.

Description

technical field [0001] The utility model relates to a punching sealing device for a composite sealed bearing, which belongs to the technical field of bearing manufacture, and in particular relates to a punching sealing device for making a composite sealed bearing. Background technique [0002] Bearing is an important basic component of various mechanical equipment. Its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. At the same time, the sealing of the bearing is also one of the important technical indicators. , the composite sealed bearing is a new type of bearing structure, which uses the hobbing technology of the outer ring of the bearing to make the steel dust cover and the outer ring of the bearing tightly combined, which fully overcomes the large gap between the three-lip seal structure of the rubber sealing ring and the inner ring of the bearing. The friction torque prevents the ph...

[0002] Bearing is an important basic component of all kinds of mechanical equipment. Its precision, performance, life and reliability play a decisive role in the precision, performance, life and reliability of the main engine. At the same time, the sealing of the bearing is also one of the important technical indicators. , the composite sealed bearing is a new type of bearing structure, which uses the hobbing technology of the outer ring of the bearing to make the steel dust cover and the outer ring of the bearing tightly combined, which fully overcomes the large gap between the three-lip seal structure of the rubber sealing ring and the inner ring of the bearing. The friction torque prevents the phenomenon of turning circle, increases the sealing strength, improves the quality and service life of the bearing, but in the production of this kind of bearing, the steel dust cover needs to be bent and deformed after stamping and embedded in the sealing groove, so that the steel The dust cover and the sharp corner of the hobbing teeth are occluded and fastened. The bearing sealing device and processing method in the prior art cannot achieve this effect, and most of the existing bearing seals are manually assembled, which is inefficient, so it is urgent to change Based on the existing bearing sealing process idea, develop a new type of composite sealed bearing stamping sealing device
