Description

Positioning device applied to retainer manufacturing equipment for tapered roller bearings {a position rectifier for taper roller bearing retainer manufacture apparatus}

The present invention relates to a positioning device applied to a retainer manufacturing apparatus for tapered roller bearings, and more particularly, to a rectangular groove on the side in the retainer manufacturing apparatus for tapered roller bearings having mass productivity by allowing a plurality of processing processes to be automatically continued. When the punched cup-shaped first molded product is transferred to the face forming machine, the taper can improve the working efficiency by correcting the transfer position of the molded product so that the rectangular groove of the molded part can be exactly matched to the fixing protrusion formed on the face forming machine. A positioning device applied to a retainer manufacturing device for a roller bearing.

In general, the tapered roller bearing has a shape as shown in FIG. 7, and is used for driving parts of front and rear wheels of automobiles, differential, machine tools, railway vehicles, rolling mills, construction machines, unloading conveying machines, printing machines, and reducers. Cylindrical rollers are mounted on the side rectangular grooves of the retainer shown in FIG.

In the conventional method of manufacturing a retainer for a tapered roller bearing having such a shape, a molded article formed of a cup-shaped conical tube having a bottom by using a press machine is supplied to a side puncher, and a tapered roller is formed on the sidewall of the molded article. A window forming process of obtaining a first molded article by shearing a rectangular groove equal to the side shape of the sheet; A chamfering molding process of gently chamfering the rough edges of the inner edge of the rectangular groove of the first molded product to obtain a second molded product; It is possible to mass-produce the retainer by the expansion-molding process to obtain a completed retainer by shearing a circular hole on the bottom surface of the conical tube of the second molded article after the process.

The first molded article having a plurality of rectangular grooves formed at equal intervals on the sidewalls through the window molding process is mounted on the fixing member of the surface forming machine formed on the outer surface of the fixing protrusion corresponding to the rectangular grooves. It is to chamfer the edges smoothly.

However, in the conventional tapered roller bearing retainer configured as described above, when the first molded article is supplied to the fixing member of the face forming machine, the fixed protrusion of the fixing member and the rectangular groove of the first molded article often do not coincide. As the surface treatment is not made properly, not only the defect rate increases but also causes the failure of the surface treatment machine, which causes a problem in that work efficiency is lowered.

The present invention has been made to solve the problems of the prior art, by accurately matching the first molded article formed with a plurality of rectangular grooves at equal intervals on the side with the fixing member of the face forming machine to be quickly and accurately in the shortest time It is an object of the present invention to provide a positioning device applied to a retainer manufacturing apparatus for a tapered roller bearing that not only significantly lowers the defect rate of production but also improves work efficiency.

The object of the present invention described above is to eject the discs one by one from the hopper containing a molded article formed into a cup-shaped conical tube having a bottom by using a press machine, and the molded articles are discharged one by one to a side punch through a transfer conveyor, and the sidewall of the molded article A window forming process of obtaining a first molded article by shearing a rectangular groove equal to the side shape of the tapered roller in the air; A chamfering molding process of gently chamfering the rough edges of the inner edge of the rectangular groove of the first molded product to obtain a second molded product; In the tapered roller bearing retainer manufacturing apparatus comprising: an expansion-expanding molding step of shearing a circular hole on the bottom surface of the conical tube of the second molded product through the above process to obtain a completed retainer;

It is installed on one side of the surface forming machine, a guide bar of a predetermined length is installed on one side of the upper surface of the plate-shaped body, the transfer member formed at one end of the support having a fixed pin in the center to slide on the guide bar It is installed, a predetermined supply groove is formed immediately before the support portion, and the groove is formed in the lifting member spaced apart by a certain distance in front of the groove, the upper portion of the groove is provided with a narrowing for conveyance and the lower lifting member is installed The lower part of the supply groove is provided with a lifting cylinder connected to the conveying conveyor at one side, and is achieved by providing a positioning device applied to the retainer manufacturing apparatus for tapered roller bearings comprising an operation control unit controlled by a control program.
