Definitions

the invention relates to a bending system for steel bars, in particular reinforcing steel bars, with a feed conveyor, bending machine unit and ejection device, the bending machine unit having a movable bending machine, a support device and a fixedly arranged bending machine and the movable bending machine in the longitudinal direction of the support device to the stationary bending machine and back and forth Block travel is movable.
the feed conveyor of such a bending system is generally a roller table.
Block travel refers to a movement whose end position is defined by a block.
the bending machines of such a bending installation generally have a bending table and a bending plate which can be driven about a vertical axis and a bending tool, e.g.
a bending finger in the form of a bending finger, a central bending counter tool and a counter holder.
the tools described, or some of them, are interchangeable when it comes to making bends with different bending radius on steel bars.
Bending table slats and a stop on the stationary bending machine are assigned.
the feed conveyor can also have a stop. The stops can be adjusted regularly and define the end positions of the end faces of the steel bars to be bent.
the support device is designed as a table. This is no problem when it comes to bending individual steel bars. If several steel rods are to be bent at the same time, one above the other in the vertical direction, rod steel holders are required that allow this. In the known embodiment, they are connected or connectable to the table. Steel bars of different lengths require them in different positions Length corresponding steel rod mounts, which also provide support. The steel rod receptacles of the known bending system cannot simply be set up for bending steel rods of different lengths. In this respect, the known system for use in flexible production lines can be improved.
the invention has for its object to develop a bending system of the construction described above so that it can be easily adjusted to the bending of steel rods of different lengths.
the invention teaches that between the movable bending machine and the fixedly arranged bending machine at least one support device which is movable in the longitudinal direction of the support device is arranged, which has a support device table, an inlet element designed as an inclined plane, and a steel bar holder for a plurality of steel bars to be bent one above the other in the vertical direction
Steel rods and a discharge element has that the support device can be pressed from the movable bending machine in the direction of the stationary bending machine into a block travel position, that the support device can be pulled out of the block travel position via at least one length-adjustable traction means from the movable bending machine to predefinable support positions and that in addition, the support device table and independently of it the receiving width of the steel rod holder are adjustable transversely to the longitudinal axis of the support device.
corresponding support devices are also arranged on the support device side on the movable bending machine and on the stationary bending machine. Except for the support frame, these support devices can consist of identical components to the movable support device that was described above. Is regular within the scope of the invention, the bending system is equipped with a plurality of movable support devices.
the advantages achieved are to be seen in the fact that steel bars to be bent according to the invention can be supported with the aid of the supporting device during the bending process in such a way as is necessary to avoid annoying sagging.
the support device table in the bending system according to the invention is adjustable in the manner described.
the steel rod holder is adjustable in the manner described in order to be adapted to different diameters of the steel rods to be bent.
the steel rods to be bent can also be clamped in the steel rod holder.
a particular advantage is the fact that the support device can be moved in accordance with the length of the steel bars to be bent via the bending machine which can be moved anyway.
the length-adjustable traction means can be designed and length-adjustable in various ways.
a preferred embodiment is characterized in that the length-adjustable traction means can be wound onto a spool with a return spring and the unwinding length of the traction means is adjustable.
the invention teaches that a support conveyor is arranged for the support devices, the conveying plane of which can be raised or lowered to the level of the inlet element of the support device for the purpose of transferring the steel bars arranged side by side on the feed conveyor.
the level of funding via lever gear and inclined planes can be raised and lowered using actuating cylinder piston arrangements.
the bending system shown in the figures is used for bending steel bars.
the basic structure includes a feed conveyor 1, a bending machine unit 2, 3, 4 and a discharge device.
the bending machine unit 2, 3, 4 has a movable bending machine 2, a support device 3 and a fixedly arranged bending machine 4.
the movable bending machine 2 can be moved back and forth in the longitudinal direction of the support device 3 to the fixed bending machine 4 and with block travel. You can work with a wide variety of traversing drives, such as chain drives.
a support device 5 which can be moved in the longitudinal direction of the support device 3 is connected between the movable bending machine 2 and the fixedly arranged bending machine 4. This movement of this support device 5 is in the Fig. 1 has been indicated by a double arrow.
the movable support device 5 has a support device table 6, an inlet element 7 designed as an inclined plane, a rod steel holder 8 for a plurality of steel rods S to be bent in the vertical direction and a discharge element 19.
the support device 5 can be pressed by the movable bending machine 2 in the direction of the fixed bending machine 4 into a block travel position.
the arrangement is also such that the support device 5 can be pulled out of the block position by means of at least one length-adjustable traction means 9 from the movable bending machine 2 to predeterminable support positions, as it was drawn.
the arrangement is also such that the support device table 6 and independently of it the receiving width of the steel rod holder 8 are adjustable transversely to the longitudinal axis of the support device 3, depending on the bending tools used or the diameter of the steel rods S.
support devices 10 constructed accordingly are arranged on the support device side on the movable bending machine 2 and on the stationary bending machine 4.
the length-adjustable traction means 9 may be wound onto a spool with a return spring, the unwinding length of the traction means 9 being adjustable.
the support devices 5, 10 are assigned a feed conveyor 1, the level of which can be lifted or raised to the level of the inlet element 7 of the support devices 5, 10 for the purpose of transferring the steel bars arranged next to one another on the feed conveyor 1. is lowerable.
FIG. 2 It can be seen that the conveying plane over inclined planes 11 and Zylinderkol benanan extract 12 can be raised and lowered in the manner described.
This stop 13 positions the end faces of the steel bars to be bent.
Another stop 14 is located on the stationary bending machine 4. This stop 14 can be tilted as usual if the bending process requires it.
the stationary bending machine 4 also has a guide rail 15 on which the counter-holder 16 is adjustable. Bending machine bars 17 are also provided. If they interfere with the kinematics described, they can also be folded down. From a comparative view of FIGS. 1 and 2 it can be seen that this bending machine bar 17 is fastened to a table-like component 18 which can be folded down in the direction of the bow arrow shown in FIG.
