Abstract
The utility model discloses an unreeling machine reel in a pickling line. The unreeling machine reel comprises a spindle sleeve (2), a panel which only can move along the radial direction of the reel, and a push-pull rod (4), wherein the push-pull rod (4) pushes/pulls the spindle sleeve (2) so that the spindle sleeve (2) generates radial displacement; a connecting rod (5) is arranged between the spindle sleeve (2) and the panel (1); one end of the connecting rod (5) is connected with the panel (1), and the connecting rod (5) can rotate around the connection point on the panel (1); the other end of the connecting rod (5) is connected with the spindle sleeve (2), and the connecting rod (5) can rotate around the connection point on the spindle sleeve (2); when the spindle sleeve (2) is pushed/pulled, the connecting rod (5) is driven to support the panel (1) to realize expansion/contraction of the panel (1); and relatively large expansion capacity of the panel (1) can be obtained with a relatively short push/pull travel and the variation range of the reel diameter is expanded.
Description
Technical field
The utility model relates to a kind of acid pickling line unwinding machine spool, and specifically a kind of panel can be realized the acid pickling line unwinding machine spool of dilation on a large scale.
Background technology
On pickling line, thereby rotating the coil of strip rotation realization of its carrying of drive, spool unreels.At present, conventional acid pickling line unwinding machine spool structure as shown in Figure 1, realizes expansion, the contraction of spool top panel 1 by expansion mechanism, and panel 1 is stepped with the surface of core sleeve 2, presents wedge type bevel sliding.Oil cylinder drives push-pull rod 4 in 2 push-and-pulls of turning axle 3 Shang Dui core sleeves, drives panel 1 to slide on inclined-plane, realizes and expanding, as shown in Figure 2.
But the spool range of expansion of said structure is limited, as attainable range of expansion be 550-630mm, when supplied materials coil of strip internal diameter is 762mm specification, need be at spool panel 1 surface mounting wearing plate, to increase reel diameter for supporting steel coils inner ring, realization drives its rotation and unreels.
Mounting or dismounting wearing plate will cause and produce line shutdown, and mounting or dismounting operation also exists potential safety hazard, and wearing plate is expendable parts simultaneously, and use cost is higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of acid pickling line unwinding machine spool, and the diameter of this spool can be realized harmomegathus in a big way.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of acid pickling line unwinding machine spool, comprise core sleeve, only along panel and the push-pull rod of spool radial displacement, push-pull rod makes core sleeve produce radially (spool radially) displacement to core sleeve's push-and-pull, between core sleeve and panel, be provided with connecting rod, one end of described connecting rod is connected on panel, and connecting rod can rotate along the tie point on panel; The other end of described connecting rod is connected in core sleeve, and the tie point in connecting rod Ke Yan core sleeve rotates.
The surface of described core sleeve and panel is provided with protuberance, and the staggered restriction panel that is close together of the protuberance on core sleeve surface and the protuberance of panel surface is only along spool radial displacement.
Between described connecting rod and core sleeve, panel, by bearing pin, be flexibly connected.
By the expansion texture of above-mentioned employing connecting rod, Dui core sleeve carries out push-and-pull, and drivening rod support panel is realized panel dilation, can use shorter push-and-pull stroke, obtains the larger swell increment of panel, and reel diameter variation range is expanded.
Adopt spool of the present utility model to avoid mounting or dismounting operation and the consumption of wearing plate, and reduce staff's production intensity, safer.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is unexpanded spool structure schematic diagram in prior art.
Fig. 2 is the spool structure schematic diagram expanding in prior art.
Fig. 3 is the utility model structural representation.
Embodiment
As shown in Figure 3, acid pickling line unwinding machine spool comprises core sleeve 2, panel 1 and push-pull rod 4,4 pairs of core sleeve's 2 push-and-pulls of push-pull rod make core sleeve 2 produce radially (spool radially) displacement, between core sleeve 2 and panel 1, be provided with connecting rod 5, one end of described connecting rod 5 is connected on panel 1 actively by bearing pin 6, thereby connecting rod 5 can rotate along the tie point on panel 1; The other end of described connecting rod 5 is connected in core sleeve 6 actively by bearing pin 6, and the tie point in connecting rod 5 Ke Yan core sleeves 6 rotates.
Optimal state is 1 radial displacement along spool of panel, realize to expand or shrinks, and avoids axially displaced along spool of panel 1.If it is axially displaced that panel 1 produces, weaken connecting rod 5 and drive the range of expansion that can realize.
As shown in Figure 3, for guaranteeing that 1 of panel is along spool radial displacement, adopt following scheme: the surface at core sleeve 2 and panel 1 is provided with protuberance 8,7, the protuberance 8 on core sleeve 2 surfaces is close together with the protuberance on panel 1 surface 7 is staggered and (interlocks here and be close to staggered being close together in side that refers to protuberance 7,8, but not end face is staggered, be close to, as shown in Figure 3, otherwise can not realize restrictive axial displacement), thus restriction panel 1 is only along spool radial displacement.
When coil of strip internal diameter is larger, need larger-diameter spool, as shown in Figure 3, by oil cylinder, drive 4 pairs of core sleeves 2 of push-pull rod to carry out push-and-pull to the right, because the two ends of connecting rod 5 are connected in panel 1, core sleeve 2, therefore the effect lower panel 1 at connecting rod 5 expands at spool radial displacement, by the less displacement of core sleeve 2, realizes panel 1 expansion in a big way.
When coil of strip internal diameter reduces, the spool that needs small diameter, as shown in Figure 3, by oil cylinder, drive 4 pairs of core sleeves 2 of push-pull rod to carry out push-and-pull left, because the two ends of connecting rod 5 are connected in panel 1, core sleeve 2, therefore the effect lower panel 1 at connecting rod 5 shrinks at spool radial displacement, by the less displacement of core sleeve 2, realizes panel 1 contraction in a big way.
For example, the long 220mm of design connecting rod 5, initial angle is 27 °, stroke 138mm, can realize reel diameter harmomegathus scope is 550～780mm.When supplied materials internal diameter specifications vary, reel diameter realizes full-automatic coupling, avoids wearing plate mounting or dismounting operation, also avoids the consumption of wearing plate, greatly reduces personnel's working strength.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection domain of the present utility model.
