Abstract
The utility model relates to an expansion and contraction coil device, which is mainly composed of multiple arc face sector plates, step inclined faces, a hollow shaft, a core shaft, a connecting rod and a clamping plate, wherein each of the multiple arc face sector plates is connected with the core shaft through the connecting rod; the step inclined faces at the inner side of the sector plates are combined with the step inclined faces at the outer side correspondingly to the hollow shaft. Under the combined action of the connecting rod and the step inclined faces, the expansion and contraction quantity of the coil device is increased, so the utility model realizes the function that one coil device can be used for coiling steel coils with different inner diameters.
Description
Technical field
The utility model relates to a kind of roll device, is specifically related to a kind of roll device with large expansion and contraction volume that is applicable to the coil of strip that batches multiple internal diameter.
Background technology
At present, the reel that uses on the domestic reeler, major defect is: the cylindrical of being made up of quadrant can only can only batch a kind of coil of strip of internal diameter at intramedullary expansion among a small circle, has limited the expansion of coil of strip specification.Have between this, be starved of a kind of not only safe and reliable on the reeler but also applicable to the roll device with large expansion and contraction volume of the coil of strip that batches multiple internal diameter.
Summary of the invention
The present invention is directed to shortcoming above-mentioned in the roll device prior art, a kind of new roll device is provided, it is mainly by multi sphere face quadrant, ladder inclined-plane hollow shaft, mandrel, connecting rod, clamping piece is formed, every multi sphere face quadrant is connected with mandrel by connecting rod, the side steps inclined-plane combines with the corresponding outer side steps of hollow shaft inclined-plane in the quadrant, under the combined action on connecting rod and ladder inclined-plane, enlarged the breathing amount of reel, realized that a reel is applicable to the function of batching multiple internal diameter coil of strip, has overcome the deficiency that a kind of reel can only batch a kind of coil of strip of internal diameter in the prior art.
The present invention is achieved through the following technical solutions: the large expansion and contraction volume roll device, comprise clamping piece, quadrant, hollow shaft, mandrel, connecting rod, and it is characterized in that: quadrant is a multi sphere face quadrant, and the cylindrical of every quadrant is made up of three sections circular arcs; The inboard of quadrant is provided with inclined-plane in gradient, and the cylindrical of hollow shaft and the inboard corresponding section of every quadrant also relative set inclined-plane in gradient, the inclined-plane is provided with needle bearing; Steel ball and adapter plate are set on the clamping piece, and the end face of quadrant combines with steel ball; Connecting rod is provided with spring with the quadrant junction and combines with bearing pin.
Every quadrant of the present utility model is connected with mandrel by two connecting rods, each inclined-plane combines with needle bearing in the ladder inclined-plane hollow shaft ramp on the quadrant, ladder inclined-plane hollow shaft is contained on the reel bolster, ladder inclined-plane hollow shaft one end is connected with mandrel by contiguous block, guard shield is connected with the reel bolster by screw rod, reel by clamp He Key and reel bolster be fitted together.Move to the clamp direction under external force drives by mandrel, drive ladder inclined-plane hollow shaft and move to the clamp direction; Connecting rod and inclined-plane promote multi sphere face quadrant jointly and expand outwardly, thereby realize the increase of reel breathing amount.Mandrel to the motion of guard shield direction, drives ladder inclined-plane hollow shaft also to the motion of guard shield direction under external force drives, connecting rod and inclined-plane promote multi sphere face quadrant and reset.By this expansion with the purpose of the coil of strip of realizing batching different inner diameters of resetting.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.

Embodiment two:
As Fig. 3, the cylindrical of every multi sphere face quadrant 10 is made up of R1, R2, three sections circular arcs of R3.Two sections circular arcs of R1 and R3 are used for the coil of strip of little internal diameter, and R2 is used for the coil of strip of large diameter.Other is partly with embodiment one.
