Definitions
- the invention relates to a roller straightening machin for straighhtening rolled or extruded profiled element; or the like.
- profiled elements such as, for example, railway rails and other special-purpose profiled element require a two-fold straightening operation so as to obtain the necessary accuracy.
- the profiled element is first straightened along one of its axes in one straightening device and is then straightened along its other axis by straightening rollers of another straightening device, which extend in another direction to the rollers of the first-mentioned straightening device.
- a straightening plant serving this purpose could, in particular, consist of a heavy horizontal-roller straightening machine and a generally smaller vertical-roller straightening machine located immediately downstream of the horizontal roller machine.
- profiled elements of different kinds i.e. profiled elements which require straightening in the direction of two of their axes and profiled elements which only have to be straighened by a single horizontal straightening machine.
- the gap thereby created in the working path or line can be filled by a roll table, for example.
- the invention has the object of devising a way whereby machines of this kind may be used to better purpose and more economically.
- the invention proposes a roller straightening machine in which the axles of the straightening rollers are adjustable in their angular position, and more particularly from a vertical position into a horizontal position and vice versa.
- a machine of the proposed, novel kind is of great versatility. It can be used alone or in combination with one or more other devices, and offers the advantage that profiled elements of widely different kinds can be suc cessively straightened, with the adjusting procedures necessary being of a simple nature and rapidly executed. In this way satisfactory results can be obtained and better utilization of available resources achieved with relatively small expenditure.
- a frame which is shiftable on wheels is particularly suitable.
- a frame of this kind may be fitted with, for example, two lateral cheeks which hold the straightening machine by means of pivot bear ings.
- a further possible form of construction resides in arranging for the straightening machine to be tiltable about one of its edges.
- the straightening machine can easily be arranged to swivel or pivot in a frame in which it is mounted by means of mechanical, electrical or hydraulic means or drives.
- the straightening rollers can be transferred from one position into the other by arranging for a part of the machine which contains the axles of the straightening rollers to be pivotable relative to the other, stationary part of the machine.
- the pivotable part can be mounted and driven in a manner analogous to that employed when a separate frame is used.
- a convenient and versatile arrangement consists in the provision of an adjustable roller straightening machine of the above-described kind and a horizontal-roller straightening machine, particularly a large horizontal straightening machine in which the distancing between whose straightening rollers is variable.
- Each of these two machines can be shifted from the working path or line in a manner known per se.
- FIGURE 1 is a view in elevation of an adjustable roller straightening machine used in conjunction with a horizontal-roller strai htening machine which is only partially shown;
- FIGURE 2 is a side view of the adjustable straightening machine taken along the line II-II of FIGURE 1, the view looking in the direction of the arrows;
- FIGURE 3 is an elevational view of the adjustable straightening machine shown in another working position and on a larger scale
- FIGURE 4 is a view in side elevation of the machine of FIGURE 3.
- the material for straightening e.g. railway rails, first passes into a large horizontal-roller straightening machine 1, which comprises housings 2 serving to receive the axles of lower straightening rollers which are adjustable in their height as well as housings 3 intended to accommodate the axles of upper straightening rollers.
- 4 indicates a discharge or outlet block.
- the part of the machine which is not shown is analogously constructed, although an infeed or inlet block replaces the outlet block.
- This horizontal straightening machine 1 can be laterally shifted from the working path on rails 5.
- Machine 6 has eight relatively staggered axles 7 mounting associated straightening rollers and equipped with their drive means.
- the machine 6 is pivotally mounted as a unit in side cheeks 9 of a frame 10 with the interposition of pins 8, so that the machine 6 can be pivoted from a position in which the straightening axles 7 extend vertically (FIGURES 1 and 2) into a position in which they extend horizontally (FIGURES 3 and 4).
- the drive provided for actuating the pivotal movements includes a hydraulic unit 11 whose cylinder is mounted on the frame 10 and whose piston rod engages the straightening machine 6 by way of a pivot bearing.
- the machine 6 can be locked to the frame 10 in each of its two terminal positions by means of index bolts 12 or like means.
- Frame 10 per se is, like the horizontal straightening machine 1, adapted to he removed from the working path or line on rails 13. 14 indicates the floor level of the plant.
- FIG- URES 3 and 4 A further manner of operation is illustrated in FIG- URES 3 and 4.
- the whole machine 1 has been shifted as a unit from the working path and the axles 7 of the straightening rollers of the machine 6, which has remained in position, have been adjusted into their horizontal position, so that smaller profiles, for example, can now be straightened.
- an adjustable straightening machine of the above-described kind can be combined particularly advantageously with a horizontal straightening machine to form a combined plant, its uses are not limited to this form of application.
- a machine of this kind having straightening axles which can be moved from one position into the other can be used for any practical application wherethe requirement exists of treating profiled elements in different ways. If required, the straightening axles can be readily adjusted in different angular positions or through a different angular range.
- a roller straightening machine including straigh ening axles having freely projecting ends, a straightening roller carried by the free end of each axle, said axles and rollers being arranged in two parallel rows with the rollers of one row being staggered with respect to the rollers of the other row, and means for simultaneously adjusting the angular position of all straightening axles in common with the straightening rollers about an axis of rotation extending parallel to the direction of movement of the material.
- roller straightening machine as claimed in claim 1 in which the range of adjustment of the straightening axles includes a vertical position and a horizontal position.
- roller straightening machine as claimed in claim 1 in which said machine includes a frame, and a further means supporting said straightening axle pivotably mounted the frame.
- roller straightening machine as claimed in claim 3 including means whereby said frame is shiftable transversely with respect to the direction in which the material to be straightened is passed.
