Wherein: 1, positioning sleeve; 2, workpiece; 3, pressing mold; 4, push rod; 5, dish spring; 6, stripper; 7, treat the riveting bearing.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described:
Wanting product processed to require the forcing press setting pressure in the present embodiment is 2KN, and the everywhere contact area of riveting is approximately 3mm
2, radially press dark about 3.5mm.
With reference to accompanying drawing 1, the bearing riveting frock that present embodiment adopts comprises positioning sleeve 1, pressing mold 3, push rod 4, dish spring 5 and stripper 6.
Positioning sleeve is fixed on the processing base, and there is positioning through hole the center, is used to place workpiece to be processed 2 and treats riveting bearing 7.
With reference to accompanying drawing 2 and accompanying drawing 3, pressing mold is the circular slab structure that the center has the guide-localization spindle nose, and guide-localization spindle nose diameter and the internal diameter coupling of treating riveting bearing 7 add man-hour, and the guide-localization spindle nose cooperates with treating the riveting bearing clearance.Guide-localization spindle nose arranged around has the riveting muscle, and the outer profile size of riveting muscle matees with treating riveting bearing outer ring size, and the riveting muscle is used for treating that the riveting bearing is pressed into workpiece.In the present embodiment, the guide-localization spindle nose is evenly distributed with four riveting muscle.There is connecting hole at the pressing mold back, is used for being connected with forcing press.
Stripper is and the circular slab structure of pressing mold with diameter, and the stripper center has through hole, is used to pass the guide-localization spindle nose, and stripper central through hole diameter is not less than the outer profile size of riveting muscle, so that in the riveting process, the riveting muscle passes stripper.On the plate structure of stripper and pressing mold, be evenly distributed with four dish spring mounting grooves, at each dish spring mounting groove center push rod be installed, string has the dish spring on the push rod; Push rod one end is fixedly connected with the pressing mold screw thread; The push rod other end has flange, and stripper is spacing, and stripper can be along the push rod axially-movable; Moved along push rod by outside workpiece effect like stripper the dish spring is compressed, moved along push rod by the effect of dish spring workpiece is unloaded from pressing mold.
