Abstract
The utility model discloses a continuous rolling type rail-curving machine. An idle gear is jointly driven by two small gears which are respectively mounted on the output shafts of two vertical electric speed reducers, two big gears which are respectively mounted on two drive rollers are driven by the idle gear, and thereby the two drive rollers can rotate synchronously in the same direction; the two drive rollers are directly mounted on a main chassis; a pressing roller is not fixed, and is connected with a pressing oil cylinder I and a pressing oil cylinder II, the oil cylinders are extended and retracted to drive the pressing roller to slide forward and backward in a chassis, consequently, the gap between the pressing roller and the drive rollers is adjusted, the pressing roller presses with load, and the curving force of the pressing roller is transmitted onto the chassis via the pressing oil cylinder II; when the pressing roller operates, the stress directions of the two oil cylinders are opposite from each other, which is realized by applying backpressure on the pressing oil cylinder II; and the two oil cylinders are connected in series, and therefore are synchronized. The rail-curving machine has a compact structure and high productivity, occupies small floor area, can easily carry out mechanized and continuous production, and reduces the labor intensity of workers.

The specific embodiment
The bent type machine of a kind of continuous rolling-type rail as shown in Figure 1, 2 mainly is made up of rack 1, pressure roller assembling 2, depress oil cylinder I 3, depress oil cylinder II4, live-roller assembling 5, intermediate gear drive 6, vertical electric reductor 7 etc.Two vertical electric reductors 7 are by an intermediate gear drive 6 live-roller 5 of transmissions respectively, realize two live-rollers in the same way, rotation synchronously.Live-roller is fixed on the rack 1, and pressure roller 2 is fixing, and it is connected with depress oil cylinder I 3, depress oil cylinder II4, can be by the front and back slip in frame of stretching of oil cylinder, and the adjustment of realization pressure roller and live-roller roll gap and the band of pressure roller carry to be depressed.
Shown in Fig. 3,4 transmission mechanism of the bent type machine of a kind of continuous rolling-type rail by two vertical electric reductors 7, be installed in two pinions 8 on two vertical electric reductor 7 output shafts and idler gear 9 and two gear wheels 10 (band is on two live-rollers) respectively and form.Adopt two groups of electronic large speed ratio reductors to drive, can to change big motor under the situation of driving moment be small machine satisfying, reduce the load of pinion, thereby reduce the appearance and size of transmission mechanism.By two live-rollers of an idler gear transmission, not only can guarantee the rotation in the same way of two rollers simultaneously, can also realize its mechanical synchronization.In addition transmission mechanism is designed to the exposed gear transmission, but also simplified apparatus structure further reduces the appearance and size of equipment, makes its compact conformation.
As shown in Figure 5, rack 1 is the closed type structure frame, is the main bearing part of this equipment, and it comprises mainframe 11 and transmission device frame 12 two parts.Pressure roller 2 is installed on the mainframe by depress oil cylinder, and two live-rollers are directly installed on the main frame 1.The bending force of pressure roller is delivered on the frame by depress oil cylinder.On the transmission device frame 12 transmission mechanism is installed, and is fixed on the mainframe 11 and on transmission frame bearing 14, whole frame then is fixed on the plant bottom case 15 with bolt 13.Pressure roller assembling 2, live-roller assembling 5 are designed to the overhang roll structure, and roller shell is connected with key with roll shaft, fix with baffle plate.This structure roller shell is changed simple to operate, easy to maintenance.Need the operating mode of frequent replacing roller shell very suitable for workshop bent type plurality of specifications rail.Both shorten man-hour, improved productivity ratio, reduced working strength of workers again.
As shown in Figure 6, the hydraulic pressure screw-down comprises depress oil cylinder I 3, depress oil cylinder II4 two parts.Because rail bends to the bending that the radius of curvature of requirement needed multi-pass, for solving the shortcoming of the crooked rail of hydraulic press, the screw-down of this invention is designed to band and carries and to depress, and promptly rail transfers repeatedly roll extrusion continuously of realization by live-roller positive and negative under the situation of not telling head.This just needs the power energy parameter of screwdown gear enough big, and the assurance pressure roller can be realized being with when each passage is appended drafts carrying and depress.Conventional mechanical press down system also can realize big power energy parameter, but structure is also corresponding huge, adjusts inconvenience, also is not suitable for the workshop and requires the little requirement of occupation area of equipment.We select the hydraulic pressure screw-down by optimal design for this reason.Simultaneously, because pressure roller is a cantilever design, during pressure roller work, the force direction that is subjected to of two cylinders is opposite, and promptly depress oil cylinder I 3 is subjected to positive load, and depress oil cylinder II4 is subjected to negative load.This loading characteristic is to realize by depress oil cylinder II4 is provided with back pressure.Two oil cylinders then be to realize synchronously by two oil cylinders are connected.
Compare with in the past shaped steel, rail straghtener, maximum characteristics of the present invention are that power energy parameter is big, roll spacing is little.The straightener of general aligning 65Kg/m rail, its roll spacing is 1200mm.Align the rail of 150.3Kg/m, roll spacing needs more than the 2000mm usually.As pressing this parameter designing, not only the structure of equipment is huge, and the straightway that rail can't be crooked is longer, and the rail utilization rate is low.The present invention adopts the pony roll distance, and the problem of bringing is that bending force strengthens at double.For this reason, the closed frame of cast steel has been adopted in this design, has satisfied the requirement of technology.Transmission adopted large speed ratio, bi-motor input are satisfied the requirement of large driving force square simultaneously.
