Abstract
The invention designs a special second-stage expansion/shrinkage roller structure for a coiling machine. The structure is mainly a roller, and comprises coiling machine fan-shaped plates, a coiling machine mandrel and an expansion/shrinkage cylinder, wherein four coiling machine fan-shaped plates are provided; two linear T-shaped key slots are arranged on the bottom surfaces of the coiling machine fan-shaped plates in parallel; T-shaped keys are matched in the T-shaped key slots, and are fixed on the coiling machine mandrel; and the back end of the coiling machine mandrel is connected with the expansion/shrinkage cylinder. The first-stage expansion aims to normally produce to tightly support a steel coil; and the second-stage expansion aims to tightly support the steel coil because the first-stage expansion cannot tightly support the steel coil due to increased inner diameters of raw materials caused by various factors. As the two linear T-shaped key slots are arranged on the bottom surfaces of the coiling machine fan-shaped plates in parallel, the connection between the coiling machine fan-shaped plates and the coiling machine mandrel is tighter, the installation difficulty is reduced, the friction in the equipment use process is effectively reduced, and the equipment service life is prolonged.

accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is cross-sectional structure schematic diagram of the present invention;
Fig. 3 is contract cylinder detailed structure schematic diagram.
detailed description of the invention:
For making goal of the invention of the present invention, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
As Fig. 1, shown in Fig. 2, the present invention devises a kind of reeler special secondary Expansion and Contraction Reel structure, main body is reel 1, and comprise coiler sector plate 2, mandrel for recoiling machine 3 and contract cylinder 4, coiler sector plate 2 has four pieces, coiler sector plate 2 lower surface is provided with the T-shaped keyway 5 of line style that twice be arranged in parallel, be equipped with T-shaped key 6 in T-shaped keyway 5, T-shaped key 6 is fixed on mandrel for recoiling machine 3, and mandrel for recoiling machine 3 rearward end and contract cylinder 4 are interconnected.Make to be connected between coiler sector plate 2 with mandrel for recoiling machine 3 more tight, reduce installation difficulty, in equipment use process, effectively reduce friction simultaneously, extension device service life.
By coiler sector plate 2, mandrel for recoiling machine 3 and contract cylinder 4 with the use of, the object that one-level is swollen is normally produced and stretching coil of strip, the object that secondary is swollen be because raw material because of various reasons internal diameter become large and make that one-level is swollen cannot stretching coil of strip, and need secondary swollen come stretching coil of strip.
Meanwhile, in invention, mandrel for recoiling machine 3 is quadrangular shape structure, mandrel for recoiling machine 3 lateral width and coiler sector plate 2 bottom bevel similar width, avoid the situation that inner structure skew occurs in device fabrication process, consolidate the stability of equipment overall structure, possess great practicality.
And the contract cylinder 4 in this equipment is hollow cylindrical structure, as shown in Figure 3, contract cylinder 4 front end is provided with front end housing 8, rear end is provided with back cylinder cover 7, the outer side center position of back cylinder cover 7 is fixedly installed swivel joint 9, mandrel for recoiling machine 3 is through front end housing 8 center, stretch into contract cylinder 4 inner chamber, and be fixedly connected with first stage piston 10, first stage piston 10 rear end in contract cylinder 4 cavity, be provided with second piston 11, rod chamber 12 is formed between first stage piston 10 and contract cylinder 4 front end housing 8, rodless cavity 13 before being formed between first stage piston 10 and second piston 11, rodless cavity 15 after being formed between second piston 11 and back cylinder cover 7, swivel joint 9 by the oil circuit 14 that is arranged on contract cylinder 4 inside respectively with rod chamber 12, front rodless cavity 13 and rear rodless cavity 15 conducting.By swivel joint 9 and first stage piston 10 and second piston 11 with the use of the secondary breathing realizing reel 1, add adjustable coefficient in process of production, especially produce for large-scale coil of strip, controllability is better, meets the operating habit of workman.
Rodless cavity 15 and the logical oil of front rodless cavity 13 after when this reel 1 off position, the obstructed oil of rod chamber 12, by oil pressure by first stage piston 10 driven forward, first stage piston 10 drives mandrel for recoiling machine 3 anterior displacement, reel 1 undergauge.When carrying out one-level and being swollen, control rodless cavity 15 and the interior logical oil of rod chamber 12 backward, therefore first stage piston 10 drives mandrel for recoiling machine 3 to produce displacement near swivel joint 9 one end, simultaneously because second piston 11 area in rear rodless cavity 15 is greater than first stage piston 10 area in rod chamber 12, the pressure produced in rear rodless cavity 15 is large, first stage piston 10 cannot be continued after contacting with second piston 11 mobile, thus ensure that position is relatively constant.Control to the logical oil of rod chamber 12 when needs adopt secondary swollen, rear rodless cavity 15 and the inner obstructed oil of front rodless cavity 13, in rod chamber 12 oil pressure synergy under make mandrel for recoiling machine 3 produce larger displacement near swivel joint 9 one end.
Above-described embodiment is preferred embodiment of the present invention; it is not the restriction to technical solution of the present invention; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of patent of the present invention.
