Background technology
Power reel is a kind of visual plant on the steel rolling production-line, except that the only a few production line does not need, as steel rolling, pickling, degreasing, move back, smooth, slitting, rewinding, welding, coating, production line such as zinc-plated, zinc-plated have basically, uses very extensive.The hightension coiling machine is mainly used in the cold rolling single stand reversible rolling mill production line, plays the collecting belt steel, sets up the effect of milling train running tension.Reasonably coiling tension can make rolled piece keep good plate shape, can improve strip surface quality, reduces when rolling resistance of deformation to produce thinner product.But the required coiling tension of the product of different cultivars, different size has nothing in common with each other, have in addition differ greatly.
The hightension coiling machine is widely used in the single stand reversible rolling mill unit, and the control of coiling tension has important effect to the belt steel product quality, and the required coiling tension of the product of different cultivars, different size also has nothing in common with each other.During rolling ordinary band steel, coiling tension can meet the demands for about 20 tons, and during rolling stainless steel material, sometimes need nearly more than 60 tons, thereby Metallurgical Enterprise has to make such selection for adapting to the flexile market demand: or set up the requirement that the multistrand rolling production line satisfies different product, or the cost huge investment, select the production line that ability is enough powerful, realize the requirement of a tractor serves several purposes.All there is the unbefitting situation of investment return in above-mentioned two schemes.
Summary of the invention
The objective of the invention is in order to solve the problems of the technologies described above, provide a kind of and realize that on same coiling machine differential tension changes the multi-functional pull reel of control, the requirement that this pull reel is simple in structure, easy and simple to handle, can be implemented in a tractor serves several purposes has reduced investment again.
Technical scheme comprises motor, gear-box and reel mandrel, and the power shaft in described motor and the gear-box is connected, and is connected through gearshift between described power shaft and the reel mandrel.
Described gearshift comprises low-speed gear A and the high gear A that is contained in the duplicate gear structure on the power shaft through bearing holder (housing, cover), and the low-speed gear B and the high gear B that are sleeved on reel mandrel back segment, also be with shifting slide gear on the power shaft between described low-speed gear A and the high gear A, the both sides of described shifting slide gear are equipped with the tooth cover, described low-speed gear A one side and low-speed gear B engagement, opposite side is corresponding with the tooth cover of shifting slide gear one side, described high gear A one side and high gear B engagement, opposite side is corresponding with the tooth cover of shifting slide gear opposite side.
Described shifting slide gear is connected through spline with power shaft.
Also be provided with in the described gear-box and can stir shifting slide gear along the axially movable slide block of power shaft, described slide block is connected with fork outside the gear-box through connecting rod, and described fork is connected with the piston rod of gearshift oil cylinder.
The utility model changes speed reducing ratio with the coiling speed that realizes control reel mandrel, the purpose that changes coiling tension through high gear or low-speed gear respectively by power shaft; Stir shifting slide gear by slide block and realize that power shaft is connected with conversion between high gear and the low-speed gear; Drive slide block by the control oil cylinder through fork and realize the purpose of control automatically, simple in structure, easy and simple to handle, can make full use of power of motor, reduce the corresponding apparatus investment, the coiling tension scope is big, product in adapting in a big way is rolling, is suitable for the flexile market demand of Metallurgical Enterprise, has broad prospects.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
The output shaft of motor 1 is connected with power shaft 9 in the gear-box 3 through toe joint hand 2, be set with the high gear A10 and the low-speed gear A12 of duplicate gear structure on the described power shaft 9 through bearing 14, be with shifting slide gear 8 (referring to Fig. 3) through the connection of involute pattern chain on the power shaft 9 between described high gear A10 and the low-speed gear A12, described shifting slide gear 8 can move axially on power shaft 9, the both sides of described shifting slide gear 8 are equipped with and can overlap 8.1 with the tooth of high gear A10 and low-speed gear B12 engagement, described low-speed gear A12 one side and low-speed gear B13 engagement, it is 8.1 corresponding that opposite side and the tooth of shifting slide gear 8 one sides overlap, described high gear A10 one side and high gear B12 engagement, it is 8.1 corresponding that opposite side and the tooth of shifting slide gear 8 opposite sides overlap, described low-speed gear B is sleeved on gear-box 3 interior reel mandrel 4 back segments with high gear B and is connected by key with it, also be provided with in the gear-box 3 and can stir shifting slide gear 8 along power shaft 9 axially movable slide blocks 7, described slide block 7 is connected with fork 6 outside the gear-box 3 through connecting rod 15, and described fork 6 is connected with the piston rod of gearshift oil cylinder 5.
The course of work:
When coiling machine was in off working state, shifting slide gear 8 was in the centre position between high gear A10 and the low-speed gear A12, did not all mesh with high gear A10 and low-speed gear A12.Referring to Fig. 1, when needing rolling thick gauge material, coiling machine need batch at the bottom gear of big retarding ratio, control gearshift oil cylinder 5 drives fork 6 and swings to low-speed gear A12 direction, and move axially to low-speed gear A12 direction along power shaft 9 by connecting rod 15, slide block 7 corresponding drive shifting slide gears 8, until the corresponding engagement of opposite side of side tooth cover 8.1 with the low-speed gear A12 of shifting slide gear 8.At this moment, starter motor 1 drives power shaft 9 and rotates, because shifting slide gear 8 is kept engagement with low-speed gear A12, low-speed gear A12 and low-speed gear B13 also are engagement, therefore can drive corresponding low-speed gear A12, low-speed gear B13 and rotate, and reel mandrel 4 is rotated, by design to the low-speed gear radius size, realization is by the purpose of low-speed gear to the motion of reel mandrel transmission low-speed big, and coiling machine batches at the bottom gear of big retarding ratio and helps template control; Otherwise, referring to Fig. 2, during rolled sheet metal, need to batch at the top gear of coiling machine in little speed reducing ratio, the oil cylinder 5 of shifting gears this moment drives fork 6 and swings to high gear A10 direction, and move axially to high gear A10 direction along power shaft 9 by connecting rod 15, slide block 7 corresponding drive shifting slide gears 8, until the corresponding engagement of opposite side of opposite side tooth cover 8.1 with the high gear A10 of shifting slide gear 8.At this moment, starter motor 1 drives power shaft 9 and rotates, because shifting slide gear 8 is kept engagement with high gear B11, therefore can drive corresponding high gear A10, high gear B11 rotates, and reel mandrel 4 is rotated, by design, realize by the purpose of high gear to the little torque motion of reel mandrel transmitting high speed to the high gear radius size, coiling machine batches at the top gear of little speed reducing ratio and helps improving unit efficiency, and the producer can rationally shift gears according to the concrete condition of sheet material.The specific design of described high gear and low-speed gear is the routine techniques of art technology, no longer describes in detail here.
