Bearing ring rolling machine

Abstract

The invention discloses a bearing ring rolling machine which comprises a connecting shaft, a conical roller is integrally and fixedly connected to the connecting shaft, the connecting shaft is connected with a driving source on the ring rolling machine, a flow guide groove is formed in the conical roller, one end of the flow guide groove extends into the connecting shaft, a water inlet mechanism is connected to the connecting shaft, and a water outlet mechanism is connected to the water inlet mechanism. And the water inlet mechanism is connected with an external water source, and a flow dividing ring is arranged on one side of the conical roller. An external water source is conveyed into the shunting ring, so that water flow can enter the flow guide groove, the flow guide groove is formed in the conical roller, the interior of the conical roller can be further cooled, and meanwhile, the water source is discharged into the treatment pipe from the conical roller, is cooled through the treatment pipe and the treatment box body and then is sprayed out from the spray head; therefore, the surface of the conical roller can be cooled, the interior and the surface of the conical roller can be further cooled, the cooling efficiency of the conical roller is improved, and the service life of the conical roller is indirectly prolonged.

Description

technical field [0001] The invention relates to the technical field of ring rolling machine equipment, more specifically, the invention relates to a ring rolling machine for bearing rings. Background technique [0002] Ring rolling machine, also known as rolling expanding machine or hole reaming machine, is a processing equipment that causes plastic deformation of rings such as wall thickness reduction, diameter expansion, and cross-sectional profile shaping. It is mainly used for the processing of high-quality seamless rings, such as bearings. Various seamless rings such as rings, ring gears, and hubs have the advantages of low vibration, energy saving, and low cost. [0003] In practice, the processing of bearing rings generally uses a radial-axial ring rolling machine. On the basis of the radial rolling horizontal ring rolling machine, an end-face axial rolling mechanism is added. The radial rolling mechanism of the ring rolling machine Fixed on the bed, the axial rollin...

Problems solved by technology

[0004] However, the existing devices generally have a plurality of water spray heads on one side of the cone roller, so as to satisfy the cooling of the cone roller and further prolong the service life of the cone roller. It is relatively poor, which further leads to the continuous increase of the temperature on the surface of the tapered roller, which affects the service life of the tapered roller
