Embodiment two
The flow chart of the flange fabrication technology that Fig. 4 provides for the utility model embodiment two, the structural representation of the non-combined set mould of ring rolls in the flange fabrication technology that Fig. 5 provides for the utility model embodiment two, in the flange fabrication technology that Fig. 6 provides for the utility model embodiment two, preform die sleeve is contained in the structural representation of the mandrel of ring rolls, the structural representation of radial preform rolling in the flange fabrication technology that Fig. 7 provides for the utility model embodiment two, the structural representation of radial roll forming in the flange fabrication technology that Fig. 8 provides for the utility model embodiment two, see shown in Fig. 4 to Fig. 8, the present embodiment two discloses a kind of flange fabrication technology, this technique comprises the following steps:
Step S300, get steel blank block, steel blank block is made the annular flange blank 200 of rolling, and make the internal diameter of annular flange blank 200 diffuse into predetermined value, make the axial height of annular flange blank 200 be rolled down to predetermined altitude.Specifically, by steel blank block from room temperature homogeneous heating to austenitizing temperature after, after abundant insulation, pier carries out to steel blank block thick, pulling and punching, make the annular flange blank for rolling, then annular flange blank is heated to austenitizing temperature again, and annular flange blank is placed on Ring Rolling Machine, driven roller 201 is driven to rotate by the transmission (not shown) of the home roll reduction box of Ring Rolling Machine, driven roller 201 drives annular flange blank 200 to rotate, annular flange blank 200 drives the core roller 202 that contacts with annular flange blank and Centering Roll 203 to rotate, core roller 202 constantly radial feed contacts with annular flange blank 200 with maintenance, be rolled eventually through the driven roller 201 of Ring Rolling Machine and the radial direction of core roller 202 pairs of annular flange blanks, the internal diameter of annular flange blank is made to diffuse into predetermined value.The internal diameter of annular flange blank is being diffused in the process of predetermined value, rotated by the drive epicone roller 204 of the transmission of the upper tapered roller box body (not shown) of Ring Rolling Machine and lower cone roller 205, be rolled eventually through the epicone roller 204 of Ring Rolling Machine and the axis of lower cone roller 205 pairs of annular flange blanks, make the axial height of annular flange blank be rolled down to predetermined altitude.In this step S300, the span of austenitizing temperature is 860 DEG C ~ 1250 DEG C; Predetermined value is determined by the external diameter of annular flange shaping base that will obtain and the difference of internal diameter; Predetermined altitude equals the distance between the lower surface of overhead gage and the upper surface of lower baffle plate.It should be noted that, in this step S300, require that the surface of steel blank block is without major defect; In this step S300, the quality of steel blank block be greater than the steel blank block used in conventional fabrication processes quality and, and be less than the quality of two the steel blank blocks used in conventional fabrication processes; The axial height of obtained annular flange blank is the twice of the axial height of a traditional annular flange blank.
Step S301, preform mould 100 to be sleeved on the core roller 202 of Ring Rolling Machine, to adopt half-open half obturator-type to carry out radial preform rolling to the inwall of annular flange blank.Before radial preform rolling, first to determine rolling ratio, effectively can avoid the rolling defect occurring depression, overlap like this.In this step S301, annular flange blank is nipped after half-open half obturator-type pass, pre-cutter is by the cutting of annular flange blank symmetry, the degree of depth being cut into annular flange blank along with pre-cutter constantly increases, after annular flange blank is closed by overhead gage, upper pre-mould, lower pre-mould together with lower baffle plate, the internal diameter of annular flange blank constantly expands, and finally reaches the preliminary dimension of carrying out designed by radial preform rolling.It should be noted that, when preform mould carries out sub-material to annular flange blank, the situation of sub-material directly affects axial height and each position allowance distribution situation of two the annular flange shaping bases finally obtained, and by causing annular flange shaping base to occur, the situation that the defect of local is even scrapped occurs irrational sub-material; When starting sub-material, should be noted that and prevent annular flange blank from occurring climbing the wild effects such as roller.It should be noted that, after the driven roller 201 of Ring Rolling Machine drives annular flange blank 200 to rotate, annular flange blank can drive the preform mould 100 that contacts with annular flange blank and Centering Roll 203 to rotate; Carrying out in the preform operation of rolling, needing constantly to cool preform mould 100 with high-pressure cooling water, to protect preform mould.
Step S302, after completing radial preform rolling, take off preform mould from core roller, finishing die is sleeved on core roller, adopts half-open half obturator-type to carry out radial roll forming to the inwall of annular flange blank.In radial roll forming process, the internal diameter of annular flange blank expands further, until rolling completes.It should be noted that, after the driven roller of Ring Rolling Machine drives annular flange blank to rotate, annular flange blank can drive the finishing die that contacts with annular flange blank and Centering Roll to rotate; Forming in the operation of rolling, needing constantly to cool preform mould with high-pressure cooling water, to protect preform mould.
Step S303, after completing radial roll forming, takes off annular flange blank from Ring Rolling Machine, by the middle sawing from the side of annular flange blank, obtains two annular flange shaping bases.
In sum, flange fabrication technology disclosed in the present embodiment two, has re-started design to pass during annular flange blank rolling, adopts half-open half obturator-type to be rolled annular flange blank.By improving rolling than improving the internal grain size of annular flange blank and institutional framework thus improve the mechanical performance of rolling.First with preform mould, radial preform rolling is carried out to the inwall of annular flange blank, after completing radial preform rolling, with shaping die sleeve, radial roll forming is carried out to the inwall of annular flange blank.The utility model decreases rolling fire, and whole making technology only needs heating twice, has saved energy cost.By using assembling die, effectively controlling operation of rolling metal flow and motion deformation, improve the dimensional accuracy of rolling and rolling, be convenient to the flatness controlling product end surface, improve the flatness of product end surface; Saved product material and cost, it is time saving and energy saving to manufacture; Process energy consumption is little, and production efficiency is high, improves product quality.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
