The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, 2, first and second flange roller (10), (20), wherein portion is provided with hole (11), (21) that connect with rotating shaft respectively, the smooth flat arcuation conical surface (12) is arranged on the wheel rim of the first flange roller (10), adjacent wheel rim (13) radius of gyration everywhere is less than the radius of gyration of the conical surface (12) below it, the dihedral curved surface (22) that one section circular arc root is arranged on the wheel rim of the second flange roller (20), adjacent wheel rim (23) radius of gyration everywhere is less than the radius of gyration of curved surface (22) below the curved surface (22).
The shape of the last edge of staving (50) as shown in Figure 5, this is shaped as state to be processed, its flange (51) is vertical with staving (50), be fixed back and when being in turn state of staving (50), the first flange roller (10) begins to do feed motion in the effect of feed mechanism, at first on the wheel rim of roller (10) the smooth flat arcuation conical surface (12) gradually to flange (51) near and pressing to it on, flange (51) is subjected to the conical surface (12) the compressing beginning bending of roller (10), its shape as shown in Figure 6, herein roller (10) in the middle in hole (11) shaft support under also gyrate, therefore, to act on the process of flange (51) be roll extrusion bending deforming process to roller (10).Afterwards, the second flange roller (20) is started working, be that roller (20) is done feed motion under the feed mechanism effect, the shaft support rotation down that is connected in hole (21) in the middle simultaneously, by root is arranged thereon is circular-arc dihedral curved surface (22), therefore flange (51) finally is rolled into shape shown in Figure 7, adjacent wheel rim (13) radius of gyration everywhere dwindles gradually below the conical surface (12) at the wheel rim place of roller (10), and adjacent wheel rim (23) radius of gyration everywhere dwindles gradually below the curved surface (22) at the wheel rim place of roller (20), this is for fear of in roller (10), when (20) carrying out roll extrusion work, wheel rim inoperative section position and staving take place to conflict and interfere, to guarantee the carrying out of roll extrusion work.
Referring to Fig. 3,4, snapping combination roller comprises first at the bottom of the staving bucket, two snapping rollers (30), (40), wherein portion is provided with the hole (31) that connects with rotating shaft respectively, (41), first, two snapping rollers (30), (40) wheel rim middle part is provided with the curved surface (32) that the cross section is the gap shape, (42), wherein the opening degree of the gap of the first snapping roller (30) is big than the opening degree of the second snapping roller (40), first, two snapping rollers (30), (40) curved surface on the edge (32), (42) on, following adjacent wheel rim (33), (34), (43), (44) radius of gyration everywhere gradually the transition of way roller both ends of the surface dwindle, in addition, the last wheel rim (33) that the curved surface (32) at first snapping roller (30) the wheel rim place is adjacent is little than the maximum radius of gyration of lower rim (34), the last wheel rim (43) that the curved surface (42) at second snapping roller (40) the wheel rim place is adjacent is little than the maximum radius of gyration of lower rim (44), and this structure also is the interference staving of can not conflicting when guaranteeing at the bottom of the roll extrusion staving bucket snapping, the bucket end.Fig. 8 is the schematic diagram at the place, snapping limit at the bottom of the staving bucket for the treatment of snapping that puts together, Fig. 9 represents the roll extrusion process status, the i.e. machining state finished when doing feeding of the first snapping roller (30), Figure 10 are the schematic diagrames that snapping has been finished, and it is finished by the second snapping roller (40).
