The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described further:
A Workpiece structure for the retainer ring 2 of wire, as shown in Figure 1, it is divided into fillet of annulus main body, two journal stirrups and journal stirrup and annulus main body junction etc.
As shown in Figure 2, the retainer ring forming tool of wire, comprises punching pin 1, left membrane module 3, right membrane module 4, positioning molding tommy bar 5.Left membrane module 3 is fastenedly connected left mould support plate 6 and right mould support plate 8 by bolt respectively with right membrane module 4, and driving left membrane module 3,4 relative motions of right membrane module by the retainer ring of wire 2 right half part bending formings by rotating screw bolt with vice, retainer ring 2 left-half of wire and journal stirrup are respectively by positioning molding tommy bar 5 and punching pin 1 moulding.
As shown in Fig. 3-8, left membrane module 3 and right membrane module 4 are respectively by left mould support plate 6 and left template 7, right mould support plate 8 and right template 9 welding fabrications.Left template 7 and right template 9 respectively with the inside and outside moulding surface structure consistent size of the retainer ring 2 of wire, for the right half part extrusion modling of the retainer ring 2 of wire.
As shown in Figure 9, positioning molding tommy bar 5 comprises shaping axle 10, rolling bearing 11, locating shaft 12 and tommy bar 13, described shaping axle 10, locating shaft 12 are connected by rolling bearing 11 with tommy bar 13, the centre-to-centre spacing of shaping axle 10 and locating shaft 12 deducts the outer radius of a circle of shaping axle 10 and equals the exradius of retainer ring 2, locating shaft 12 is arranged in positioning center hole 16, by axle centered by locating shaft 12, to locating shaft 12 center as the exradius of retainer ring 2 is rotated, make the left side outer mold surface brake forming of retainer ring 2 take shaping axle 10 cylindricals.
