Description

Steel coil strip rewinder

Technical field

The utility model relates to a kind of rewinding mechanisms.Specifically, it is steel for the steel coil strip on backing roll falls down Band volume rewinder.It is particularly suitable on the assembly line of production steel pipe.

Background technique

It is both known about in steel pipe's production industry, the assembly line most preceding working procedure for producing steel pipe will be coiled using rewinder Steel coil strip falls down, continuously to provide steel band for later process.Rewinder therein is in opposite cloth there are two containing The axle bed set is provided with the support roller for being used to support steel coil strip between two axle beds.Wherein, two axle beds are fixed plates.By It is fixed plate in two axle beds, when steel coil strip to be installed in support roller, needs from axle bed to unload support roller simultaneously After installing steel coil strip, then the support roller with steel coil strip is sling together with boom hoisting and is placed in fixed plate.Thus As it can be seen that not only needing boom hoisting using this rewinder, the equipment needed is more, invests more, high production cost, Er Qiegong Sequence is more, operates more troublesome.

Utility model content

Problem to be solved in the utility model is to provide a kind of steel coil strip rewinder, using this device, can not only subtract Few equipment investment reduces production cost, and it is more convenient to operate.

The above problem to be solved in the utility model is realized by the following technical scheme:

It is in axle bed positioned opposite that the steel coil strip rewinder of the utility model, which includes two, is had between two axle beds for branch The support roller of steel coil strip is supportted, there are twin rollers on rear side of support roller.In the axle bed, an axle bed is fixed plate, its main feature is that: it is another One axle bed is movable axle bed.

The activity axle bed includes support, which is located at longitudinal side of support roller；There is trailing arm between support and support roller, Trailing arm one end is hinged on holder top, has arc groove on the upside of the trailing arm other end, one end of the neighbouring movable axle bed of support roller is in that can revolve Turn shape to be placed in arc groove；Have upper connecting rod and lower link between support lower part and trailing arm, upper connecting rod lower end and lower link upper end by Short axle is hinged, and upper connecting rod upper end is hinged on the longitudinal intermediate of trailing arm, and lower link lower end is hinged on the lower part of support；Support There is oil cylinder in side far from backing roll, and the piston rod of oil cylinder is hinged in the short axle between upper and lower strut.

It due to there is an axle bed in described two axle beds is movable axle bed it can be seen from above scheme.The movable axis Seat includes support, which is located at longitudinal side of support roller.There is trailing arm between support and support roller, trailing arm one end is hinged on support There are arc groove in top, trailing arm other end upside, and one end of the neighbouring movable axle bed of support roller is placed in arc groove in rotatable shape.Branch There are upper connecting rod and lower link between seat lower part and trailing arm, upper connecting rod lower end is hinged by short axle with upper connecting rod upper end, upper company Bar upper end is hinged on the longitudinal intermediate of trailing arm, and lower link lower end is hinged on the lower part of support.Support has far from the side of backing roll Oil cylinder, the piston rod of oil cylinder are hinged in the short axle between upper and lower strut.When steel coil strip need to be installed in support roller, as long as making The piston rod of oil cylinder inside contracts, and trailing arm will be driven to be rotated down around its one end hinged with support by upper and lower strut, make trailing arm One end with arc groove is detached from support roller.At this point, steel coil strip can be pushed into front of support roller and be installed by the trolley separately matched Onto support roller.Then, restarting oil cylinder keeps its piston rod overhanging, and drives trailing arm hinged with support around it by upper and lower strut One end rotate upwards, make trailing arm with moving under support roller on one end of arc groove, set the roll shaft at end where support roller In in arc groove.Compared with the background art, it when steel coil strip is installed, is not required to unload lower backing roll, is not required to boom hoisting, not only needs Equipment is few, reduces investment, reduces production cost, and reduce process, operates more convenient.

Detailed description of the invention

Fig. 1 is the steel coil strip rewinder structural schematic diagram of the utility model.

Specific embodiment

As shown in Figure 1, the steel coil strip rewinder of the utility model contains, there are two be in axle bed positioned opposite, two axle beds Between be provided with the support roller 5 for being used to support steel coil strip 6.Twin rollers 13 are provided on rear side of support roller.In two axle beds, an axle bed For fixed plate 9, another axle bed is movable axle bed.

The activity axle bed contains a support 1, which is located at longitudinal side of support roller 5.Support 1 and support roller 5 Between be provided with trailing arm 8,8 one end of trailing arm is hinged on 1 top of support by pin shaft 4, is processed into concave arc on the upside of 8 other end of trailing arm Shape, to form an arc groove on the upside of the end of trailing arm 8, one end of the neighbouring movable axle bed of support roller 5 is in by bearing can It is contorted to be placed in arc groove.Be provided with upper connecting rod 3 and lower link 11 between 1 lower part of support and trailing arm 8, the lower end of upper connecting rod 3 with The upper end of lower link 11 is hinged by short axle 10, and 3 upper end of upper connecting rod is hinged on the longitudinal direction of trailing arm 8 by a pin shaft 4 Centre, 11 lower end of lower link are hinged on the lower part of support 1 by another pin shaft 4.Support 1 is arranged far from the side of support roller 5 There is oil cylinder, the cylinder body 2 of oil cylinder is connected to the 2 vertical centres in 1 outside of support, and 12 outer end of piston rod of oil cylinder is hinged on upper connecting rod 3 In short axle 10 between lower link 11.

It when steel coil strip 6 need to be installed in support roller 5, first inside contracts the piston rod 12 of oil cylinder, and passes through 3 He of upper connecting rod Lower link 11 drives trailing arm 8 to be rotated down around its one end hinged with support 1, and the one end of trailing arm 8 with arc groove is made to be detached from branch Support roller 5.Later, steel coil strip 6 is pushed into front of support roller 5 by the trolley separately matched and is installed in support roller 5.And then it opens Dynamic oil cylinder keeps its piston rod 12 overhanging, and drives trailing arm 8 to rotate upwards around its one end hinged with support 1 by upper and lower strut, Make trailing arm 8 with moving under support roller 5 on one end of arc groove, is placed in the roll shaft at 5 place end of support roller in arc groove.

When rewinding, the steel band outer end in steel coil strip 6 is sent to twin rollers 13 using craft, is clamped in steel band outer end Between the roller of two relative rotation in twin rollers 13.In this way, being realized with the relative rotation of 13 two rollers of twin rollers The purpose of steel band is successively provided for next procedure.
