The utility model solves the problems of the technologies described above the technical scheme that is adopted: the straightening drum of the waste and old building iron of a kind of straightening is characterized in that: comprise straightening axle, clamping plate, several displacement bolts and several straightening moulds; Described straightening axle is fixed on clamping plate one end, and portion axially has the straightening shaft through-hole within it; To having straightening mould through hole, several straightening moulds are connected successively and are installed in the clamping plate at described straightening mould inner shaft, and the straightening mould through hole in several straightening moulds communicates successively, and described straightening mould through hole communicates with the straightening shaft through-hole again; Described displacement bolt is installed on the clamping plate, and it cooperates with the straightening mould.
Straightening mould through hole described in the utility model is the hourglass shape, and the area of its bottom surface, left side is greater than the area of bottom surface, the right.
In the formation that several straightening moulds of the utility model are connected into successively, the bottom surface, the right of previous straightening mould through hole is connected with the bottom surface, the left side of a back straightening mould through hole.
Straightening axle described in the utility model is two, is separately fixed at the two ends of clamping plate.
The utility model also comprises straightening shaft pulley and bearing block, and the straightening shaft pulley is fixedly set on the straightening axle, and the bearing block turning set is contained on the straightening axle.
Straightening mould described in the utility model is 9.
Straightening mold materials described in the utility model is spheroidal graphite cast-iron or steel alloy.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2,9 straightening moulds of use are rotated straightening, keep original performance thereby make waste and old building iron not influenced by pulling force, and the energy scale removal, have guaranteed the inherent quality of reinforcing bar, and straightening building weak point is expected continuously.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1～Fig. 5, the utility model embodiment comprises straightening axle 1, clamping plate 2, displacement bolt 3, straightening mould 4, straightening shaft pulley 5 and bearing block 6.
Straightening axle 1 is two, is separately fixed at the two ends of clamping plate 2.The inside of straightening axle 1 has straightening shaft through-hole 11 in the axial direction, and straightening shaft through-hole 11 is to connect whole straightening axle 1, and its axis is the axis of straightening axle 1.Straightening axle 1 material is the 45# steel.
Straightening mould 4 inside have straightening mould through hole 41 in the axial direction, and straightening mould through hole 41 is to connect whole straightening mould 4, and its axis is the axis of straightening mould 4.Straightening mould through hole 41 is the hourglass shape, and the area of its bottom surface, left side 411 is greater than the area of bottom surface, the right 412.In the present embodiment, straightening mould 4 is 9, and 9 straightening moulds 4 are connected successively and are installed in the clamping plate 2.In the formation that these 9 straightening moulds 4 are composed in series, the straightening mould through hole 41 of each straightening mould 4 is connected successively and is communicated, and each straightening mould through hole 41 is parallel, and the bottom surface, the right of previous straightening mould through hole is connected with the bottom surface, the left side of a back straightening mould through hole.In the formation that 9 straightening moulds 4 are composed in series, the straightening mould through hole 41 that is positioned at the primary straightening mould 4 of formation communicates with the straightening shaft through-hole 11 of a straightening axle 1, being positioned at last the straightening mould through hole 41 of straightening mould 4 of formation communicates with the straightening shaft through-hole 11 of another root straightening axle 1, like this, two straightening shaft through- holes 11 and 9 straightening mould through holes 41 communicate each other.According to the waste and old building iron of different materials, it is spheroidal graphite cast-iron or steel alloy that straightening mould 4 can be selected material for use.
3 rotations of displacement bolt are installed on the clamping plate 2, and it contacts with straightening mould 4.Displacement bolt 3 is a plurality of, and each displacement bolt 3 is all supporting a nut 8, and also supporting on the displacement bolt 3 that is positioned at clamping plate 2 both sides have a pressing plate 7.Each straightening mould 4 is furnished with 3, tops that are positioned at straightening mould 4 of two displacement bolts, a bottom that is positioned at straightening mould 4 at least.Displacement bolt 3 is a hexagon-headed bolt, swing offset bolt 3 and nut 8, and displacement bolt 3 can move up and down, and promotes straightening mould 4 simultaneously and moves up and down, and has regulated the upper and lower displacement amount of straightening mould 4, adjusts the flexibility of waste and old building iron in the utility model.
