Description
Technical field
The utility model relates to steel rolling equipment, refers to a kind of Novel strip steel roll device particularly.
Background technology
At present, in some silicon steel sheet finished strip coil of strip surface existing defects pleat prints.Except band steel material own is soft and except the factor of the thin easy generation blemish of thickness, main cause is exactly whether the machining accuracy of steel rolling equipment roll device in strip coiling process reaches instructions for use, the particularly precision of reel circularity.But the domestic existing each manufacturer of reel industry is all difficult to the requirement on machining accuracy realizing reel circularity, band steel coil of strip surface easily produces pleat print defect.
Summary of the invention
The purpose of this utility model will provide a kind of structure simple Novel strip steel roll device exactly, can meet the requirement that band steel coil of strip surface does not produce impression.
For achieving the above object, Novel strip steel roll device designed by the utility model, comprise main shaft, its special character is, described main shaft is connected with oil cylinder by the pull bar be movably arranged in spindle through-hole, described main shaft outer setting has pyramid sleeve, described pyramid sleeve is fixedly linked by cotter pilotage and pull bar, described pyramid sleeve has surface groove and trapezoidal skewed slot vertically, described surface groove and trapezoidal skewed slot in the circumferential interval are arranged, described pyramid sleeve is provided with fanning strip and closed wedge, described fanning strip inner surface is provided with rank, inclined-plane, rank, described inclined-plane and surface groove are slidably matched, described closed wedge inner surface is provided with trapezoidal rank, described trapezoidal rank and trapezoidal skewed slot are slidably matched, the outer surface of described fanning strip and closed wedge is combined into a full circle, adjacent fanning strip and closed wedge stitching portion are provided with stress relief groove.
Further, the cross section of described stress relief groove is isosceles right triangle, is set to the stress that isosceles right triangle is easier to decompose fanning strip and closed wedge stitching portion.
Further, between adjacent fanning strip and closed wedge, the quantity of described fanning strip and closed wedge is respectively 3 ~ 4.The size requirement different according to band steel coil of strip, arranges three groups or four groups of fanning strips and closed wedge.
Further, the outer surface of described fanning strip and closed wedge is combined into the full circle that a diameter is Φ 450 ~ Φ 610mm, with the size requirement that adaptive zone steel coil of strip is different.
Fanning strip and closed wedge are arranged on pyramid sleeve by inclined-plane cooperation by the utility model, pyramid sleeve is arranged on main shaft, and be connected by cotter pilotage with the pull bar being arranged on main shaft and leading to deep hole, pyramid sleeve is axially moved with pull bar when oil cylinder pulls pull bar, and while pyramid sleeve axially moves, fanning strip and closed wedge are axially motionless, only do radial motion, and radial direction is inclined-plane is slidably matched, to realize drum-expanding function, and by devising a stress relief groove at adjacent fanning strip and closed wedge binding site, which reducing when batching steel band makes steel band extrude the defect of impression because binding site stress is large.
Compared with prior art, the utility model overcomes when batching steel band and makes because binding site stress is large steel band extrude the defect of impression, compensate for the defect causing pleat to print because processing circularity is bad simultaneously, the target that the surface finally realizing inner ring of steel coil prints without any pleat, improves strip coiling quality.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Novel strip steel roll device as shown in Fig. 1 ~ Fig. 6, comprises main shaft 1, and main shaft 1 is connected with oil cylinder by the pull bar 2 be movably arranged in spindle through-hole, and main shaft 1 outer setting has pyramid sleeve 3, and pyramid sleeve 3 is fixedly linked by cotter pilotage 3.3 and pull bar 2.Pyramid sleeve 3 has multiple surface groove 3.1 and trapezoidal skewed slot 3.2 vertically, and surface groove 3.1 and trapezoidal skewed slot 3.2 in the circumferential interval are arranged.Pyramid sleeve 3 is provided with fanning strip 4 and closed wedge 5.According to the size of reel, the quantity of fanning strip 4 and closed wedge 5 is respectively 3 ~ 4.Fanning strip 4 inner surface is provided with rank, inclined-plane 4.1, rank, inclined-plane 4.1 and surface groove 3.1 are slidably matched, close wedge 5 inner surface and be provided with trapezoidal rank 5.1, trapezoidal rank 5.1 are slidably matched with trapezoidal skewed slot 3.2, and the outer surface of fanning strip 4 and closed wedge 5 is combined into the full circle that a diameter is Φ 450 ~ Φ 610mm.Adjacent fanning strip 4 is provided with stress relief groove 7 with closed wedge 5 stitching portion.The cross section of stress relief groove 7 is approximately isosceles right triangle.
During utility model works, fanning strip 4 is arranged on pyramid sleeve 3 by inclined-plane cooperation, closing wedge 5 is also arranged on pyramid sleeve 3 by inclined-plane cooperation, pyramid sleeve 3 axially moves with pull bar 2 when oil cylinder pulls pull bar 2, and while pyramid sleeve 3 axially moves, the fanning strip 4 be arranged on pyramid sleeve 3 is axially motionless with closed wedge 5, only do radial motion, rank, inclined-plane 4.1 and the radial ramp of surface groove 3.1 of fanning strip 4 are slidably matched, the trapezoidal rank 5.1 closing wedge 5 are slidably matched with the radial ramp of trapezoidal skewed slot 3.2, thus realize drum-expanding function.When reel swollen to greatest circle time, fanning strip 4 and closed wedge 5 are interspersed and are combined into a full circle, wherein in the stress relief groove 7 of adjacent fanning strip 4 with closed wedge 5 binding site, decreasing when batching steel band 6 makes steel band 6 extrude impression (being commonly called as pleat print) because binding site stress is large, meanwhile also can make up the defect causing pleat to print because processing circularity is bad, the target that the surface finally realizing inner ring of steel coil prints without any pleat.
