Abstract
The invention relates to a manufacturing method for a F22 alloy bell-shaped case forged piece and a special core roller. The manufacturing method comprises carrying out the steps of gathering, punching, broaching, expanding, rolling and forming, and the like on ring blank. The manufacturing method is characterized in the rolling and forming step, the ring blank is positively positioned, and is mounted into a bell-shaped core roller mould which is mounted on a transition mounting base and separated from a central mandrel in a sleeved mode, wherein a small-aperture bottom end of the ring blank faces downwards, and a small-aperture top end of the ring blank faces upwards; the bottom end of the ring blank is supported by a rolling platform; then, the central mandrel is dropped from the above, is inserted into the ring blank and an inner hole of the core roller mould from the top end, and is connected with the core roller mould and the transition mounting base through a key; and after being combined, the core roller mould and the central mandrel are matched with a main roller of a rolling mill to roll the ring blank. The manufacturing method has the beneficial effects that: the ring blank is firstly sleeved into the core roller mould, and then, the central mandrel and the core roller mould are connected, so that the ring blank can be loaded and rolled in a positive positioning mode, and therefore, rotation stability and roll-wrapping stress of the ring blank are improved, and a rolling success rate is increased.
Description
Technical field
The present invention relates to the manufacturing process technology field of special-shaped forge parts, specifically the manufacture method of a kind of F22 alloy bell casing forging and special core roller.
Background technology
F22 alloy bell casing forging is the large scale special-shaped ring forging of one that aerospace field is conventional, and as shown in Figure 1, its external surface is complicated, and upper and lower side bore difference is large, usually adopts ring embryo rolling mill practice to manufacture.The upper odd test core roller that existing milling train uses designs for integral type, add man-hour, the ring embryo of the bell casing forging of F22 alloy must be inverted, and makes heavy caliber bottom upward, small-bore top down, guarantee integral type core roller inserts ring embryo (core roll shape is also inverted bell) smoothly, makes ring embryo be inserted in core roller mould, but in the operation of rolling, the inversion of ring embryo is unfavorable for its steady rotation and embraces roller stressed, very easily cause forging rolling failure, thus produce waste product, cause economic loss.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes the manufacture method of a kind of F22 alloy bell casing forging and special core roller, solve prior art and the ring embryo of bell for F22 alloy casing forging is inverted rolling, stock is caused to rotate unstable and embrace roller discontinuity thus cause the technical problem of rolling failure, guarantee the steady of the operation of rolling, improve and be rolled into power.
The technical solution used in the present invention is as follows:
The manufacture method of the bell casing forging of a kind of F22 alloy, comprise and poly-material is carried out to ring embryo, punching, reaming, swollen hole, the steps such as roll forming, it is characterized in that: in described roll forming step, ring embryo is just put, heavy caliber bottom down, small-bore top is inserted in upward and is arranged on transition mount pad, the bell core roller mould be separated with mandrel, ring embryo bottom is supported by rolling platform, then described mandrel is fallen from top, the endoporus of ring embryo and core roller mould is inserted by top, and be connected with core roller mould and transition mount pad by key, milling train home roll is coordinated to be rolled ring embryo after core roller mould and mandrel combination.
For the special core roller that F22 alloy bell casing forging manufactures, comprise mandrel, core roller mould, transition mount pad, rolling platform and lower mount pad, wherein, mandrel is separated with core roller mould, is connected by key; Transition mount pad internal diameter coordinates with outside diameter of mandrel, and transition mount pad is connected with lower mount pad by external screw thread, and on lower mount pad, cover has bearing; Rolling platform is arranged at core roller mould bottom, it is characterized in that: described core roller mould is bell and with heavy caliber bottom down, small-bore top is just put upward, and be arranged on transition mount pad, described mandrel is after ring embryo is inserted in core roller mould, fall from top and insert ring embryo and core roller mould endoporus, being connected with core roller mould and transition mount pad by key; Mandrel, core roller mould, transition mount pad and lower mount pad in the operation of rolling with ring embryo synchronous rotary.
Beneficial effect of the present invention is: have employed and first ring embryo is inserted in core roller mould, again by mode that mandrel is connected with core roller mould, enable that ring embryo loads in the just mode of putting, rolling, improve the smooth rotation of ring embryo and to embrace roller stressed, improve and be rolled into power.
