Description

Technical Field

[0001] The invention relates to a ring rolling machine device, in particular to a ring rolling machine assembly device. Background Art

[0002] Ring rolling machine is a plastic processing equipment that can reduce the wall thickness, expand the diameter, and form the cross-sectional profile by causing continuous local plastic deformation of the ring. It is widely used in the large-scale production of various ring forgings such as aircraft engine casings, sealing rings, bearing rings, and automobile wheels. At present, most ring rolling machines are unidirectional rolling. The ring rolling machine assembly used in this rolling method only needs to control the main roll and the core roll to deform the ring blank to reduce the wall thickness and expand the diameter, thereby producing a ring forging. However, this ring rolling machine device cannot maintain a continuous and stable rolling process. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a ring rolling machine assembly device which can keep the ring rolling process continuous and stable.

[0004] In order to solve the above technical problems, the ring rolling machine combination device of the present invention mainly includes a main roller, a core roller, a holding roller and a tapered roller, and is characterized in that the holding roller is fixed to one end of a connecting rod, and the other end of the connecting rod is fixed to a rotating interface of a ring rolling machine base, and one end of the connecting rod connected to the holding roller can rotate and swing around one end of the rotating interface on a horizontal plane.

[0005] Particularly, the diameter of the main roller D1 = 1000 mm to 1200 mm, the diameter of the core roller D2 = 200 mm to 400 mm, and the diameter of the embrace roller D3 = 400 mm to 500 mm.

[0006] Particularly, the length S1 of the connecting rod is 1200 mm to 1500 mm.

[0007] Particularly, the distance S2 from the rotation interface to the Y axis is 300 mm to 400 mm; and the angle α of the rotation interface deviating from the Y axis is 15° to 20°.

[0008] In particular, the tapered roller consists of an upper tapered roller and a lower tapered roller, the upper tapered roller and the lower tapered roller have the same shape and size, both are truncated cone shapes, the cone angle β of the tapered roller is 30°~35°, the diameter of the lower table surface is D4=650mm~700mm, and the distance S2 from the circumference of the upper table surface to the apex of the cone is 250mm~300mm.

[0009] Particularly, the upper end of the circumferential surface of the lower tapered roller is a rolling horizontal line.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The ring rolling machine assembly device of the present invention adopts a main roller, a core roller, an embrace roller and a tapered roller combination. The embrace roller is fixed to one end of a connecting rod, and the other end of the connecting rod is fixed to a rotating interface of the ring rolling machine base. One end of the connecting rod connected to the embrace roller can rotate and swing around one end of the rotating interface on a horizontal plane, which can ensure that during the rolling process, the position of the ring is adjusted as the ring grows, thereby ensuring that the rolling process is continuous and stable.
