Summary of the invention
For above problem, the object of the present invention is to provide a kind of prestressing force fine-rolling screw nut punch forming device, be intended to utilize the mode of hot extrusion to replace traditional machining mode to process prestressing force fine-rolling screw nut, and to the shape molding of prestressing force fine-rolling screw nut, bore endoporus operation and be integrated into a procedure, raise labour productivity, reduce processing cost, be applicable to produce in enormous quantities.
The present invention is achieved in that a kind of prestressing force fine-rolling screw nut punch forming device, the upper ejector pin comprising base, cylinder and be fixedly linked with described cylinder piston termination, also comprise: pull bar, described pull bar upper end is connected with described cylinder piston, and lower end is connected with draw-bar seat; Described draw-bar seat is positioned on base; Whirligig, described whirligig lower end is connected with draw-bar seat, and upper end is connected with lower push rod; Described lower push rod is connected with draw-bar seat by whirligig; External mold, described external mold and base are fixedly linked.We provide a kind of prestressing force fine-rolling screw nut punch forming device, be intended to utilize the mode of hot extrusion to replace traditional machining mode to process prestressing force fine-rolling screw nut, and to the shape molding of prestressing force fine-rolling screw nut, bore endoporus operation and be integrated into a procedure, raise labour productivity, reduce processing cost, be applicable to produce in enormous quantities.
Further technical scheme of the present invention is: described lower push rod side has screw thread.This design can be processed the nut of different screw thread, further increases the applicability of described prestressing force fine-rolling screw nut punch forming device.
Further technical scheme of the present invention is: described lower push rod and described whirligig are interconnected by screw thread.This design makes described lower push rod to replace, and we can change corresponding lower push rod for needing the difference of the nut produced, this just makes described prestressing force fine-rolling screw nut punch forming device just can produce different nuts when only changing a lower push rod, further increases the applicability of described prestressing force fine-rolling screw nut punch forming device.
Further technical scheme of the present invention is: also comprise fixture in described prestressing force fine-rolling screw nut punch forming device, lower end and the base of fixture are fixedly linked, and upside and the cylinder of fixture are fixedly linked.Described fixture is mainly used to fixing described nut punch forming device.
Further technical scheme of the present invention is: described outer die device is also provided with external mold fixator outward; Described external mold fixator comprises clamping bar, and described clamping bar is threaded; Described clamping bar upper end is provided with compressing tablet; The top of described clamping bar is provided with compressing tablet nut.Described external mold fixator is mainly used to fixing external mold.
Further technical scheme of the present invention is: described external mold fixator can be removed.So just can change different external molds, this just makes described nut punch forming device just can produce different nuts when only changing an external mold, further increases the applicability of described prestressing force fine-rolling screw nut punch forming device.
The invention has the beneficial effects as follows: utilize the mode of hot extrusion to replace traditional machining mode to process prestressing force fine-rolling screw nut, and to the shape molding of prestressing force fine-rolling screw nut, bore endoporus operation and be integrated into a procedure, raise labour productivity, reduce processing cost, be applicable to produce in enormous quantities.
