Abstract

The utility model relates to an arrangement structure for wrapping rolls in a ring rolling mill, which comprises a vertical wrapping roll and an inclined wrapping roll. Both the vertical wrapping roll and the inclined wrapping roll are cylindrical structurally, the axis of the vertical wrapping roll is parallel to the center axis of a ring forge piece, the upper end of the inclined wrapping roll is inclined to the center of the ring forge piece, and an included angle between the axis of the inclined wrapping roll and the center axis of the ring forge piece ranges from 3 degrees to 5 degrees. The arrangement structure is applicable to a ring rolling process of ring force pieces, and avoids the problem of creeping, unstable rolling and eccentricity of the ring force pieces in the rolling process.

Description

Embrace the arrangement of roller in the ring rolls

Technical field

The utility model relates to the production technical field of ring rolling spare, relates in particular to the arrangement of embracing roller in a kind of ring rolls.Be mainly used in the bundle ring process of ring rolling spare, belong to ring rolling spare technical field of mold.

Background technology

Use very extensively in the ring rolls production of ring rolling spare enterprise at home and abroad, be mainly used in the process of rolling of all kinds of annular forging pieces.The rolling sketch map of ring rolls is as shown in Figure 3, the expansion of ring rolls home roll 1 and core roller 2 responsible ring rolling spare 5 radial diameter, and awl roller 4 control loop forging 5 height are embraced rollers 3 for two and are responsible for the steady rolling of ring rolling spare 5 and become round.As shown in Figure 4, two armfuls of rollers 3 were vertical placement in the ring rolls in the past, occur easily when rolling ring rolling spare 5 rolling steadily with climb the roller phenomenon, and be prone to cause the off-centre of ring rolling spare 5, be lowered into round rate, product rejection rate is high.

The utility model content

The utility model technical problem to be solved is: provide a kind of ring rolling spare that can make in the operation of rolling, to avoid occurring climbing roller, and rolling not steady, the arrangement of armful roller in the ring rolls of eccentric phenomena.

For addressing the above problem; The technical scheme that the utility model adopts is: the arrangement of embracing roller in the ring rolls; Comprise that structure is cylindrical vertical armful of roller and tilts to embrace roller; The axis of described vertical armful of roller and the central axis of ring rolling spare parallel setting, and the upper end that tilts to embrace roller tilts towards the centre of ring rolling spare, and the angle angle between the central axis of the axis of armful roller that tilts and ring rolling spare is 3 ~ 5 degree.

The beneficial effect of the utility model is: embrace the arrangement of roller in the above-mentioned ring rolls, help avoiding ring rolling spare roller to occur climbing in rolling, rolling not steadily and eccentric phenomena, improved product percent of pass widely.

The specific embodiment

Through specific embodiment the arrangement of embracing roller in the utility model ring rolls is done further to describe in detail below.

Like Fig. 1, shown in Figure 2; Embrace the arrangement of roller in the ring rolls; Comprise that structure is cylindrical vertical armful of roller 31 and tilts to embrace roller 32; The central axis of the axis of described vertical armful of roller 31 and ring rolling spare 5 parallels setting, and the upper end that tilts to embrace roller 32 tilts towards the centre of ring rolling spare 5, and the angle of the angle a between the central axis of the axis of armful roller 32 that tilts and ring rolling spare 5 is 3 ~ 5 degree.

The operation principle of the utility model is: as shown in Figure 1, and when ring rolls is rolling, the expansion of ring rolls home roll 1 and core roller 2 responsible ring rolling spare 5 radial diameter; Awl roller 4 control loop forging 5 height; Vertical armful roller 31 and tilts to embrace the steady rolling of roller 32 responsible ring rolling spares 5 and become circle, and as shown in Figure 2, roller 32 is embraced in its medium dip can apply a vertical component to ring rolling spare 5; Stop ring rolling spare 5 to climb roller and eccentric phenomena, improved product percent of pass widely.

The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.

Claims

1. embrace the arrangement of roller in the ring rolls; Comprise that structure is cylindrical vertical armful of roller and tilts to embrace roller; It is characterized in that: the axis of described vertical armful of roller and the central axis of ring rolling spare parallel setting; The upper end that tilts to embrace roller tilts towards the centre of ring rolling spare, and the angle angle between the central axis of the axis of armful roller that tilts and ring rolling spare is 3 ~ 5 degree.
