The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
(center line is upper and lower to be two kinds of operating modes) as shown in Figure 1 to Figure 3, the band flexible working face uncoiler of a kind of electrichydraulic control of the present utility model, coiler mandrel comprise main shaft 1, pyramid 2, four fanning strips 3, pull bar 5, crossbeam 6 and pull bar driving mechanisms.Main shaft 1 is quill shaft, pyramid 2 is positioned on the main shaft 1, pyramid 2 outer surfaces are provided with two-stage sloping platform face at least, fanning strip 3 inboards are slidingly matched with pyramid 2 sloping platform faces and are arranged at pyramid 2 peripheries, constitute tubular, the front end of each fanning strip 3 connects a cambered plate 8, and the periphery of fanning strip 3 is provided with rubber bush 4.Pull bar 5 is arranged in the main shaft 1, and pull bar 5 rear ends are connected with above-mentioned pyramid 2 by crossbeam 6, but drive lip cone 2 slide with respect to fanning strip 3, and pull bar 5 rear ends pass main shaft 1 and by outer support 18 supports; Pull bar 5 front ends pass main shaft 1 and cylinder lever connecting rod driving mechanism, and pull bar 5 passes part and is with rotating shaft, and rotating shaft is provided with gear 19, are used for external driving and make the reel rotation, and the rotating shaft front end links to each other with the pull bar driving mechanism through adpting flange 9, connection support 11.Pull bar driving mechanism of the present utility model comprises cylinder body 15 and right end cap 13 thereof, left end cap 16, be provided with piston 14 in the cylinder body 15, piston rod 12 front ends that link to each other with piston 14 are provided with displacement transducer 17, the rear end is connected with pull bar 5 by the catcher 10 that connects in the support 11, by relative distance L control pull bar 5 positions of external electric liquid systems control piston bar 12 with cylinder body 15.In addition, for preventing the axial float of rubber bush 4, be provided with baffle plate 7 in fanning strip 3 rear ends.
The utility model has the footpath work of expanding, undergauge to unload volume and crosses the undergauge three kinds of operating modes of press-offing, and switches by the position of pull bar 5 according to actual needs, and as shown in Figure 1, the concrete operation principle of three kinds of operating modes is:
1) the reel footpath work of expanding: external electric liquid systems control piston bar 12 relatively moves with cylinder body 15, and then drives pull bar 5 and move, and makes piston 14 move to the C position, and at this moment, the drum diameter maximum is the operate as normal position;
2) the reel undergauge unloads volume: external electric liquid systems control piston bar 12 relatively moves with cylinder body 15, and then drives pull bar 5 and move, and makes piston 14 move to the D position, and reel is contracted to the coil stripping diameter, so that coil of strip unloads volume;
3) reel is crossed undergauge and press-offed: external electric liquid systems control piston bar 12 relatively moves with cylinder body 15, and then drive pull bar 5 and move, make piston 14 move to the E position, reel is contracted to path, this moment, the reel circumscribed circle diameter was less than rubber bush 4 static apertures, for the dismounting of rubber bush 4.
Core of the present utility model is the setting of rubber bush 4 protective layers, and the working face that reel is contacted with the strip is the flexible working face, has avoided cold-strip steel to produce the problem that reel is creased in uncoiling and coiling process, makes strip surface quality good; Further, by the external electric liquid systems piston 14 positions are controlled, can be according to the needs of operation, realize that expand footpath work, undergauge of reel unloads volume and cross the press-off switching of three kinds of operating modes of undergauge, and the installation and removal of rubber bush 4 are easy, non-slip, and the coil of strip coil stripping is convenient.Because rubber bush 4 and double-piston classification oil cylinder are applicable to uncoiler, the coiler mandrel of multiple structure and specification.So the utility model protection domain is not limited to above-described embodiment.
