A rectangular pyramid (3) is installed on a hollow spindle (4) by the clearance fit of two guide flat keys, a shaft and a hole, four T-shaped guide keys (2) are respectively fixed in a corresponding groove on four inclined planes of the rectangular pyramid (3) through screws, four cylinder head sliding blocks (1) are installed on the rectangular pyramid (3) and the hollow spindle (4) through the T-shaped guide keys (2), the inclined planes, copper sliding plates (5) and a pressure plate (6), and eight copper sliding plates (5) are respectively fixed on the cylinder head sliding blocks (1) and the pressure plate (6) through screws; the utility model uses a shrinkable short column head form to form a double column head uncoiler or recoiling machine; compared with a double pyramid head uncoiler and recoiling machine, the utility model does not bear big axial force; compared with a long drum shrinking type uncoiler and recoiling machine, the utility model has a sleeve with two-point bearing, on arm hanging and favorable stress and rigidity.

Description

A kind of sleeve clamping device

Technical field:

The utility model relates to strip material cold rolling technology field, especially relates to being used in the cold rolling unit of aluminium sheet band; Uncoiler in the finishing unit or the sleeve clamping device on the coiling machine.

Background technology:

At present, employed uncoiler and coiling machine have two kinds of patterns in the present cold rolling unit of aluminium sheet band, the finishing unit: a kind of is the uncoiling of bipyramid head, coiling machine, such uncoiling, coiling machine use the garden conical surface, come closing sleeve to finish uncoiling, to batch work by axial force distribution, its shortcoming is that axial force is big, is subjected to very big influence the service life of bearing; A kind of is the uncoiling of long carriage expanding-contracting type, coiling machine, and such uncoiling, coiling machine use cantilevered, long collapsible drum to come closing sleeve to finish uncoiling, to batch work, and its shortcoming is that arm length, reel root are stressed greatly, rigidity is bad.

Summary of the invention:

For overcoming the deficiency in the background technology, the utility model discloses a kind of sleeve clamping device, this sleeve clamping device can solve above two types uncoiling, the existing defective of coiling machine effectively.

For achieving the above object, the utility model adopts following technical scheme:

Described sleeve clamping device, rectangular pyramid is by two dive keys and axle, the matched in clearance in hole is installed on the hollow spindle, four T type feather keys are separately fixed at screw in the corresponding groove on four inclined-planes of rectangular pyramid, pass through T type feather key at four socket cap slide blocks, the inclined-plane, copper shoe, pressing plate is installed on rectangular pyramid and the hollow spindle, eight copper shoes are separately fixed on socket cap slide block and the pressing plate by screw, four pressing plates are by being separately fixed at bolt on the socket cap slide block, two copper sheathings are installed in the hollow spindle two ends, push rod by the matched in clearance with copper sheathing be installed in hollow spindle be used to wear in the slotted hole, two ends have screw thread to link to each other with rectangular pyramid and hydraulic cylinder respectively; Coupling sleeve is fixed by bolts on the hollow spindle; Hydraulic cylinder is fixed by bolts on the coupling sleeve, is provided with swivel coupling in the outside of hydraulic cylinder.

Described sleeve clamping device, the upper surface of four socket cap slide blocks are the face of cylinder, and through identical, lower surface is the inclined-plane in the straight warp on the face of cylinder and the sleeve, and the inclined-plane is provided with T type groove.

Described sleeve clamping device, the outer surface of rectangular pyramid are that the gradient on four orthogonal inclined-planes, inclined-plane is identical with the gradient of socket cap slide block lower surface, and its inner surface is made as the cylinder pass.

Described sleeve clamping device, the front portion of hollow spindle is provided with the face of cylinder, and the straight warp on the face of cylinder cooperates with rectangular pyramid endoporus homotype, is the longitudinally guiding step surface between the leading portion of its hollow spindle and the back segment, the alignment of shafts is provided with the slotted hole of being used to wear, and push rod can be moved in the hole.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

The utility model uses the short column capitiform formula of energy harmomegathus, forms double capital uncoiling or coiling machine; Compare with the uncoiling of bipyramid head, coiling machine, the utility model does not bear big axial force; Compare with the uncoiling of long carriage expanding-contracting type, coiling machine, the utility model sleeve is 2 supportings, and arm sling not is stressed, rigidity is all preferable.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Among the figure: 1-socket cap slide block; 2-T type feather key; 3-rectangular pyramid; 4-hollow spindle; 5-copper shoe; 6-pressing plate; 7-copper sheathing; 8-push rod; 9-: coupling sleeve; 10-hydraulic cylinder; 11-swivel coupling.

Specific embodiment:

In Fig. 1,2; A kind of sleeve clamping device, rectangular pyramid 3 is by two dive keys and axle, the matched in clearance in hole is installed on the hollow spindle 4, four T type feather key 2 usefulness screws are separately fixed in the corresponding groove on four inclined-planes of rectangular pyramid 3, pass through T type feather key 2 at four socket cap slide blocks 1, the inclined-plane, copper shoe 5, pressing plate 6 is installed on rectangular pyramid 3 and the hollow spindle 4, eight copper shoes 5 are separately fixed on socket cap slide block 1 and the pressing plate 6 by screw, four pressing plates are by being separately fixed at bolt on the socket cap slide block 1, two copper sheathings 7 are installed in hollow spindle 4 two ends, push rod 8 by the matched in clearance with copper sheathing 7 be installed in hollow spindle 4 be used to wear in the slotted hole, two ends have screw thread to link to each other with rectangular pyramid 3 and hydraulic cylinder 10 respectively; Coupling sleeve 9 is fixed by bolts on the hollow spindle 4; Hydraulic cylinder 10 is fixed by bolts on the coupling sleeve 9, is provided with swivel coupling 11 in the outside of hydraulic cylinder 10.
