The utility model solves its technical problem and takes following technical scheme to realize:
A kind of five roller tensioning apparatus, comprise base base, base riser, fixing roller seat, stationary roll, slide, free roller seat, free roll and hydraulic cylinder, both sides, base upper end are all shaped with base riser, on the base riser of base upper end one side, be fixed with a fixing roller seat, this is fixedly provided with three stationary rolls of vertically installing in roller seat uniformly at intervals, on the base between another base riser of stationary roll and base, slidable adjustment is provided with a slide, the side that this slide closes on stationary roll is fixed with a free roller seat, in this free roller seat, be symmetrically arranged with two free rolls of vertically installing, an other middle side part of slide is fixed with a slide earrings, the base riser middle part corresponding with slide earrings is fixed with a base earrings, between this base earrings and slide earrings, a hydraulic cylinder is installed, it is characterized in that: described free roll and stationary pipes are hollow structure, and the upper end of free roll and stationary roll is all connected with a cooling water pipe by swivel joint, this cooling water pipe is connected to the cooling water tank being arranged on base, described stationary roll with fixedly between roller seat, by locking device, be connected.
And described locking device comprises fixedly wedge and movable tapered wedge, fixedly the both sides of roller seat are all shaped with symmetrical back bending structure, and this back bending symmetrical configuration is sleeved on base riser both sides, base riser and fixedly leave gap between roller seat; On base riser, be fixed with a fixing wedge with the interstitial site of fixing roller seat by a plurality of bolts, this is wedge and fixedly regulate and be embedded with a movable tapered wedge between roller seat fixedly.
Advantage of the present utility model and good effect are:
1, this device adopts larger roller diameter, increases the rotating speed of roll neck and reduction roller, effectively promotes the service life of roller and bearing.
2, this device leads to cooling water pair of rollers by swivel joint and carries out coolingly in real time, simultaneously because roller inside is full of cooling water, has strengthened the rotary inertia of roller, to improving, with steel tensile force, has played certain effect.
3, the earrings of the fixer cylinder pressure of this device is connected with base and slide by bolt, has simplified process, has saved cost.
4, the movable roll of this device peace is fixed on free roller seat, stationary roll is fixed on fixedly on roller seat, movable roll frame, slide and base are by locking with the locking device of wedge shape wedge structure, during normal work, only need strike tight wedge, can guarantee reliability by wedge self-locking locking, during roll change, with bolt, unclamp wedge, i.e. replaceable movable roll or free roll, easy to operate, effectively shorten the repair time.
5, the utility model structure intensity is high, shock resistance good, wear-and corrosion-resistant, long service life, adopts cooling water pair of rollers cooling in real time, simplifies process, cost-saving, and promotes crudy, easy to maintenance, promotes production line operation rate.
