The branch chains can enable a tensioning plate to connect the tensioning plate, a first rod, a tensioning drive rod and a second rod into a whole in a tensioning movement process, the tail end of each branch chain is connected with sliding blocks, and the sliding blocks can move directionally on the slide guides fixed on the second rolling bearing. A mandrel threaded rod is fixedly connected with the mandrel, thread transmission between the mandrel threaded rod and the tensioning drive rod is achieved through threads, and a driving angle bar is fixedly connected to the tail end of the mandrel. The winch feeding tensioning mechanism is flexible in movement, obvious in tensioning effect and capable of achieving radial tensioning movement of the mandrel, and has good tensioning performance for kinds of industrial coiled material needing winch and feeding.
Description
Technical field
The utility model relates to a kind of stretching device, particularly a kind of novel stretching device for industrial elevator feeding.
Background technology
, for slim sheet material in technical application,, in order to produce the convenience with transportation, usually adopt the form that is wound around rolling, in use need further processing after the sheet material unreel, because the board quality of rolling is large, increased the unreel difficulty, greatly reduce work efficiency.At present, the unreel mode of widespread use uses the fixing steel pole in two ends to pass the coil of strip axle center, by pulling sheet material, makes coil of strip center and steel pole generation cliding friction.Because the coil of strip center is not tensioned, coil of strip easily deforms, and has improved difficulty of processing.In addition, the cliding friction between coil of strip center and steel pole has increased the power that pulls to sheet material, is unfavorable for the isotropic maintenance of sheet material.
Therefore, need the effectively tensioning of a kind of sheet material for industrial elevator feeding in engineering, the stretching device that the while coil of strip can freely rotate around the tightening device axle center.
Summary of the invention
For existing the problems referred to above to existing in the use procedure of coil unreel, the utility model provides a kind of elevator feeding stretching device.Specifically, be to utilize screw mechanism and parallel-crank mechanism relative theory, a kind of novel elevator feeding stretching device based on parallel institution is provided, can be widely used in the coil of strip elevator feed system in industry.
The technical solution of the utility model is:
a kind of elevator feeding stretching device, described elevator feeding stretching device, comprise rolling bearing one, rolling bearing two, axle and three tensioning side chains that structure is identical, rolling bearing one connects axle and frame, axle is connected with three slide rails by rolling bearing two, the circular spindle baffle plate is fixedly connected with axle, side chain can make tensioning plate in the strained movements process with tensioning plate, the first bar, the tensioning drive spindle, the second bar connects as one, the end of every side chain is connected with slide block, slide block can be on the guide rail that is fixed on rolling bearing two displacement, axle thread rod and axle are connected, and by screw thread, realize and the transmission of tensioning drive spindle screw thread, drive angle bar and be fixedly connected on the axle end.
The beneficial effects of the utility model are:
The utility model purpose is to provide a kind of elevator feeding stretching device, and this mechanism has following characteristics:
(1) elevator feeding stretching device adopts three side chains in parallel to realize strained movements, can effectively realize the even tensioning to coil of strip;
(2) elevator feeding stretching device of the present utility model can rotate around Pivot Point Center, can effectively reduce the power that pulls in the unreel use procedure;
(3) rationally use screw mechanism as the tensioning actuating device, can self-locking after tensioning, keep stable tensile force;
(4) this mechanism tension effects is obvious, and is simple to operate, and motion flexibly, is easy to technical application.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, elevator feeding stretching device is fixed on frame the structure of a kind of elevator feeding of the utility model stretching device.elevator feeding stretching device, comprise rolling bearing 1, rolling bearing 24, axle 2 and three tensioning side chains that structure is identical, rolling bearing 1 connects axle 2 and frame, axle 2 is connected with three slide rails 5 by rolling bearing 24, circular spindle baffle plate 3 is fixedly connected with axle 2, side chain can make tensioning plate 7 in the strained movements process with tensioning plate 7, the first bar 8, tensioning drive spindle 9, the second bar 11 connects as one, the end of every side chain is connected with slide block 6, slide block 6 can be on the guide rail 5 that is fixed in rolling bearing 24 displacement, axle thread rod 10 is connected with axle 2, and with tensioning drive spindle 9, realize the screw thread transmission, drive angle bar 12 and be fixedly connected on axle 2 ends.
when mechanism works, by the purlin car, coil of strip 13 is sling and made coil of strip 13De center be inserted in three tensioning plate 7 outsides, the central party borehole jack that drives spanner 14 is entered on the driving angle bar 12 of axle 2 ends, pull driving spanner 14 and make axle 2 relatively rotating around the generation of the axle center of axle 2 and guide rail 5 under the effect of rolling bearing 24, the rotation of axle 2 drives axle thread rod 10 and rotates simultaneously, axle thread rod 10 produces relative rotation with tensioning drive spindle 9, make tensioning drive spindle 9 axially move under threaded function, the tensioning plate 7 ends slide block 6 that is connected, cause tensioning plate 7 can only radially move under the constraint of guide rail 5, moving axially of tensioning drive spindle 9 makes the first bar 8 and the second bar 11 be tending towards vertical, tensioning plate 7 is outwards motion radially, the tension of realization to coil of strip.Whole stretching device can be along mechanism's center shaft flexible rotating under the effect of rolling bearing 1.This elevator feeding stretching device tensioning is even, successful, and the industrial all kinds of coiled materials of elevator feeding that need are had good tension performance.
