The ring rolling mill is divided into closed and open ring rolling mills according to the technological mode, the closed ring rolling mill sleeves the heated blank with holes on the core roller, and the blank is driven to rotate by the inner edge of the rolling roller, so that the thickness of the blank is reduced and the diameter of the blank is enlarged. The open ring rolling mill is used for sleeving a heated blank punched with a hole on a core roller, and the blank is driven to rotate by the outer edge of a rolling roller, so that the thickness of the blank is reduced and the diameter of the blank is enlarged.
At present, chinese utility model patent that the publication number of granting is CN202316876U discloses a large-scale horizontal ring rolling machine, including the lathe bed, install roll roller, core roller, conical roll from the left hand right side in proper order along its lathe bed central axis, the bilateral symmetry of roll roller distributes and has a pair of armful arm, all is connected with on every armful arm and embraces the roller. And a laser measuring device is also arranged on the central axis of the lathe body and is positioned on the right side of the conical roller. The core roller is of an upward-pulling type, and the core roller is of a short type. And a hydraulic cylinder is arranged above the core roller and used for mounting the core roller. Supporting rollers are distributed on two sides of the core roller, and the supporting rollers are symmetrical relative to the central axis of the lathe bed. The conical rollers are symmetrically distributed up and down, the conical rollers comprise upper rollers, lower rollers and a support in a frame shape, the upper rollers and the lower rollers are both located at one end, close to the core roller, of the support, the upper rollers can slide up and down at one end, close to the core roller, of the support, the support can freely move along the central axis of the lathe bed, and the upper surfaces of the lower rollers of the conical rollers and the surface of the carrier roller are on the same horizontal plane. The rolling roller can move along the central axis of the bed body to adjust the distance between the rolling roller and the core roller. The working principle is as follows:
during operation, the core pulling roller is firstly mounted on the hydraulic cylinder, the heated annular forging piece is sleeved on the core roller, and the outer side wall of the core roller is attached to the inner side wall of the annular forging piece. And then moving the conical roller to enable the upper roller of the conical roller to abut against the upper end face of the annular forging, enable the lower roller of the conical roller to abut against the lower end face of the annular forging, and enable the two holding rollers to abut against the outer side wall of the annular forging. Finally, the roll is rotated and moved toward the core roll to extrude the annular forging. In the process of extruding the annular forging, water is manually sprayed to the roller (comprising the core roller, the holding roller and the conical roller) through the water pipe so as to achieve the purposes of cooling and removing oxide skin on the surface of the annular forging. The laser measuring device measures the outer diameter of the annular forging in real time in the ring rolling process, and once the outer diameter of the annular forging reaches the preset size, the rolling roller stops rotating and stops moving towards the core roller.
The above prior art solutions have the following drawbacks: when the ring is ground, the temperature of the annular forging is generally in the state of 1000-1200 ℃, and sparks and scrap iron are sputtered in the extrusion process of the annular forging, so that operators operating the ring grinding machine are easily injured, and in severe cases, the operators are scalded, and potential hazards are brought to the personal safety of the operators.
