Abstract
The utility model belongs to the field of slitting processing, and particularly relates to an uncoiling sleeve, which comprises a main shaft and an oil cavity arranged in the main shaft, wherein one suspended end of the oil cavity is enclosed, the other end of the oil cavity, which is connected with a rack, is connected with an oil inlet pipeline and an oil return pipeline which are arranged in the rack, a group of through holes are arranged along the axial direction of the wall thickness of the main shaft, the group of through holes include four uniformly distributed through holes, another group of through holes are symmetrically distributed along the radial direction of the wall thickness of the main shaft, each through hole is provided with a piston rod, one end of each piston rod, which is close to the oil cavity, is connected with a piston, the other end of each piston rod is connected with a support block, each support block is in a strip shape, the outer surface of each support block is in an arc shape, and the support blocks are distributed in the direction parallel to the axial direction of the main shaft. When the diameter of a middle through hole of a roll material is changed, the diameter of the uncoiling sleeve is correspondingly changed through the flexing of the support blocks, so that the roll material is arranged steadily, and when the uncoiling sleeve is rotated, the roll material is prevented from loosing and shaking, so that material loading is completed smoothly.
Description
Technical field
The utility model belongs to the slitting manufacture field, is specifically related to a kind of uncoiling sleeve.
Background technology
In the household appliances, as refrigerator, washing machine shell and body of a motor car, adopt thin-walled steel plate processing and fabricating.Raw material plant is that the material plate that steel factory provides is continuous rolling, collects simultaneously the coiled strip that is curled into a volume one volume, and the coiled strip of purchase above-mentioned raw materials factory of materials enterprise carries out blank to it and is machined to dimension.Coiled strip is allocated and transported to the slitting equipment place with driving from material stock and is carried out blowing, leveling, cutting operation processing, and blowing operation wherein is that coiled strip is put on the uncoiling sleeve of emptying equipment.
Coiled strip is put on the uncoiling sleeve of emptying equipment, be kept the through hole direction at uncoiling sleeve and coiled strip middle part consistent, and keep the former diameter greater than the latter, after coiled strip is enclosed within on the uncoiling sleeve, add fixture block in both gaps, guarantee that becoming flexible can not appear in coiled strip.Because the diameter of uncoiling sleeve is larger than the through-hole diameter at coiled strip middle part, both cooperate rear generation eccentric, coiled strip are placed not steady, and when the uncoiling sleeve rotated, coiled strip easily became flexible, rocks.
Summary of the invention
The purpose of this utility model provides a kind of uncoiling sleeve, guarantees that uncoiling sleeve and coiled strip are concentric, guarantees the coiled strip placement steadily, avoids simultaneously becoming flexible, rocking of coiled strip.
For achieving the above object, the utility model has adopted following technical scheme: a kind of uncoiling sleeve, comprise the oil pocket that main shaft and main shaft inside are offered, the end sealing that oil pocket is unsettled, the oil-feed that arranges in the other end of oil pocket and the frame, return line links to each other, main shaft is axially offered two groups or more through hole along it, one group of through hole comprises four through holes, the hole core direction of described through hole is arranged along the radial direction in main shaft cross section, four through holes on the same group evenly distribute in circumference range, each through hole is provided with piston rod, each piston rod links to each other with piston near an end of oil pocket, and the other end connects a back-up block, and back-up block is strip, the outside is curved, the axially parallel of its arranged direction and main shaft.
By such scheme as can be known, when coiled strip middle through-hole diameter changes, change accordingly the diameter of uncoiling sleeve by stretching of back-up block, coiled strip is placed steadily, when the uncoiling sleeve rotated, coiled strip had been avoided becoming flexible, rocking, thereby successfully finishes material loading.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
A kind of extension type uncoiling sleeve, comprise the oil pocket 40 that main shaft 20 and main shaft 20 inside are offered, oil pocket 40 unsettled ends seal, the oil-feed that arranges in the other end of oil pocket 40 and the frame, return line links to each other, main shaft 20 is axially offered two groups or more through hole along it, one group of through hole comprises four through holes, the hole core direction of described through hole is arranged along the radial direction in main shaft 20 cross sections, four through holes on the same group evenly distribute in circumference range, each through hole is provided with piston rod 41, each piston rod 41 links to each other with piston 42 near an end of oil pocket 40, the other end connects a back-up block 10, and 10 of back-up blocks are strip, and the outside is curved, the axially parallel of its arranged direction and main shaft 20, as shown in Figures 1 and 2.
As further preferred version of the present utility model: consider that two piston rods, 41 supported pieces 10 may make back-up block 10 unbalance stress, simultaneously can be owing to the weight of coiled strip, make two piston rods 41 be difficult to supported piece 10, the wall thickness of described main shaft 10 is offered through hole more than two groups along its axial symmetry, and one group of through hole comprises four through holes.
Further, when considering blowing, may be owing to back-up block 10 flexible, produce impression with the extruding of coiled strip inner ring, the symmetrical rubber sleeve 30 that is arranged with on the outer wall of described back-up block 10.The utility model is in actual practical process, when coiled strip middle through-hole diameter changes, by to oil pocket 40 interior oilings, oil pressure impels piston rod 41 actions, and piston rod 41 drives coupled back-up block and makes 10 expanding-contracting actions, thereby changes the diameter of uncoiling sleeve, coiled strip is placed steadily, when the uncoiling sleeve rotated, coiled strip had been avoided becoming flexible, rocking, thereby successfully finishes material loading.
