Abstract
A ring rolling mill for rolling production of a seamless ring piece with a special-shaped cross section is characterized in that an upper conical roller, a lower conical roller and a main roller which are arranged on the ring rolling mill and used for forming shape contour of the cross section of the ring piece are arranged in the same position of the ring rolling mill; the upper conical roller and the lower conical roller can rotate along own axes and can vertically move in a straight line in the axial direction of the ring piece; the main roller can rotate along own axis and can move in a straight line in the radial direction of the ring piece; only one rolling deformation area exists during ring piece rolling deformation, the upper surface, the lower surface and internal and external diameter surfaces of the ring piece are restrained by the surfaces of the upper conical roller, the lower conical roller and the main roller in the rolling deformation area, so that the forming of the ring piece cross section is guaranteed; and two pairs of holding rollers are symmetrically arranged on the outer side of the ring piece, accordingly, the stability of a rolling process of the ring piece is guaranteed, and accurate control for size and shape of the ring piece with the special-shaped cross section is facilitated.
Description
Technical field
The invention belongs to metal material processing field, relate to a kind of ring rolls that is specifically designed to Rolling Production odd-shaped cross section seamless ring.
Background technology
The seamless ring of odd-shaped cross section has a wide range of applications in fields such as Aero-Space, automobile, machinery, chemical industry, the energy.At present, odd-shaped cross section seamless ring is produced main traditional radial rolling ring rolls or the footpath-axial associating rolling ring rolls of adopting and is completed production.But radial rolling ring rolls can only make ring internal-and external diameter surface form certain contour shape, cannot realize the shaping of ring upper and lower end face.And the radial rolling district of traditional footpath-axially rolled ring rolls and the axially rolled district same place on equipment not, two differ 180 ° to deformed area in the radial position of ring, on relative position, cause being rolled contour shape that ring Yi Xiang rolling district obtains and be easy to distortion while arriving another to rolling district and lose shape rotating 180 °, special-shaped ring cross sectional shape is difficult to accurate control.On the other hand, traditional ring rolls is only furnished with a pair of armful of roller, and ring with odd-shaped cross section is complex-shaped, and in the operation of rolling, the Flowing Hard of material is to control, and this can cause the operation of rolling unstable, and the geomery of ring is difficult to be guaranteed.The problem such as adopt the ring rolls Rolling Production ring with odd-shaped cross section of traditional footpath-axially to there will be that the operation of rolling is unstable, cross sectional shape can not accurately be controlled, follow-up machining amount is large, stock utilization is low and production efficiency is not high.
Summary of the invention
The object of the invention is to overcome above-mentioned traditional radial rolling ring rolls and the footpath-deficiency of axial associating rolling ring rolls when rolling special-shaped section ring parts, a kind of ring rolls that is specifically designed to Rolling Production odd-shaped cross section seamless ring is provided.This rolling ring function effectively guarantees the cross sectional shape of ring, reduces follow-up machine-finish allowance, improves stock utilization.
For achieving the above object, the technical scheme that odd-shaped cross section seamless ring rolling ring rolls involved in the present invention adopts is: upper and lower cone roller and the king roller of ring rolls are arranged in equipment same position, and ring footpath-axially rolled Shi Qi radial deformation district and axial deformation district overlap.Embrace rollers for four and be close to ring outside, along king roller center and ring circle center line connecting direction and vertical direction thereof symmetry between two.Initial ring blank is square-section, is positioned on ring rolls workbench.The profile of upper and lower cone roller and king roller has the contour shape corresponding with ring.Upper and lower cone roller and king roller, along axis rotation separately, drive ring continuous rotation.The radial feed of upper and lower cone roller along the axial feed of ring, king roller along ring, two are positioned at ring the same area to deformed area, and the ring of rolling simultaneously makes that its section thickness and height dimension reduce, profile is shaped, ring enlarged-diameter.Embrace roller for four and ring is retrained and lead, correct the not round phenomenon in the operation of rolling, guarantee the stable of ring rolling process.Ring rolls control system guarantees that ring outside dimension meets the requirements of simultaneously, and each work roll arrives desired location, and cross section just completes shaping.
The beneficial effect of odd-shaped cross section seamless ring rolling ring rolls involved in the present invention is: the radial and axial contact in rolling of seamless ring is arranged in the same place of equipment, the upper and lower end face in ring cross section and internal-and external diameter surface are subject to roll constraint simultaneously, guarantee that ring cross section profile is shaped.The roll by replacing with different profiles, this ring rolls can be produced the seamless ring with different cross section shape.In ring outside, arrange two breaker rolls, guarantee the stability of the operation of rolling, be conducive to the accurate control of odd-shaped cross section seamless ring geomery.
Accompanying drawing explanation
Fig. 1 is the roll arrangement schematic diagram of the ring rolls that the present invention relates to.
Fig. 2 is ring blank (a) and final ring (b) shaping form schematic diagram.
1-epicone roller in Fig. 1,2-king roller, bores roller under 3-, and 4-embraces roller, 5-signal roller, 6-ring.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the present invention is further described.
Embodiment
The ring blank of the present embodiment is the square-section ring that Fig. 2 (a) indicates, and final roll forming ring shape is as shown in Fig. 2 (b).Square-section ring blank is transferred on ring rolls after heating and thermal insulation, and king roller, epicone roller and the rotation of lower cone roller, drive ring rotation.Epicone roller is along the axially downward speed feeding with 0.8mm/s of ring; Lower cone roller does not axially move along ring; King roller along ring radially to the ring center of circle with the speed feeding of 0.5mm/s; For the signal roller of measuring, record ring external diameter, feed back to control system and control in real time an armful roller position, guarantee ring rolling stability.After 20s rolling, king roller and epicone roller stop straight-line feed but still continue rotation, and ring is rotated 2-3 again and turned, and final cross section is shaped, and ring external diameter reaches required size, as shown in Fig. 2 (b).After completing rolling, ring is transferred to cooling zone, waits for subsequent treatment.
The present embodiment shows, odd-shaped cross section seamless ring Rolling Production involved in the present invention effectively guarantees ring with odd-shaped cross section roll forming by rolling ring function, and ring size has degree of precision, and stock utilization and production efficiency are high.
It should be noted that, embodiment shown in Fig. 1 and Fig. 2 is wherein a kind of embodiment that the present invention introduces, those skilled in the art on this basis, can roll out the seamless ring of various radial and axial abnormity at an easy rate by the modes such as geomery of change king roller and upper and lower cone roller.
