Definitions
- the invention relates to a device for bending rod-shaped material into concrete reinforcement elements, having a frame for supporting a material feed device and a support for bending members which is rotatably mounted on the frame about the feed axis and is adjustable relative to the frame.
- the support for the bending members has a driven turntable which is rotatably mounted on the frame in both directions about the feed axis and is provided with a passage opening for the rod-shaped material.
- An arm extends away from the turntable and is provided with a straight guide aligned with the turntable opening, through which the material passes.
- the carrier has at its free end a bending head which is equipped with bending mandrels which can be rotated or pivoted about an axis perpendicular to the guide.
- the known design has the particular disadvantage that brackets with larger leg lengths cannot be effectively supported by the support arm and run the risk of deforming under their own weight.
- the object of the invention is to avoid the disadvantages described and to provide a device of the type mentioned in the introduction, which makes it possible to bend rod-shaped material properly in various bending planes and with any leg lengths and to separate the bent elements in a simple manner.
- the invention is also intended to continuously bend allow spatial reinforcement and so-called bow baskets.
- the device according to the invention is characterized in that the carrier is designed as a material support table that can be adjusted in a predetermined angular position relative to the frame, on which a cutting device upstream of the bending elements in the material feed direction is provided for separating the rod-shaped material from the material strand after the bending process.
- the invention advantageously creates an adjustable support surface for the curved reinforcement elements, which ensures a perfect shaping of the elements without risk of deformation, the elements being able to be safely separated without great design effort and without any time delay.
- a bar for electrical contact with the bent material is provided on the support table at a distance from the bending members, via which the rotary movement of the table can be controlled. In this way, if the curved element is inadvertently lifted off the support table, the support table is readjusted in a new contact with the element.
- a receptacle is provided below the support table for reinforcement elements falling downward in the horizontal position of the support table, the receptacle preferably being rotatable.
- the rotary bearing of the support table is preferably designed as a pipe guide coaxial to the feed axis for the rod-shaped material.
- the rod material to be bent is fed in the direction of arrow P1 from a material supply, not shown, via a straightening device, also not shown, and is passed along a feed axis X-X.
- the bending device consists essentially of two parts 1 and 2, part 1 being arranged stationary and part 2 being rotatably connected to part 1 about an axis of rotation coinciding with the feed axis X-X in accordance with the double arrow P2.
- Part 1 consists of a stationary frame 3 which has a feed roller set 4, an additional straightening roller set 5 connected downstream of the feed roller set 4 to compensate for any deformation of the rod material by the feed rollers, and a rotary drive 6 for the part 2 rotatably fastened to part 1 by means of a bearing 7 wearing.
- the part 2 consists essentially of a support table 10 which carries a cutting device 8 and a bending head 9.
- a measuring wheel 11 is expediently integrated, by means of which the length of the rod material passing through is detected and the cutting device 8 is actuated after reaching the predetermined length of the material to be bent, in order to thereby separate the finished bow from the material strand. It is also possible within the scope of the invention to arrange a measuring wheel provided with a corresponding counter roller directly in front of the cutting device 8 on the support table 10.
- the feed roller set 4 and the straightening roller set 5 are covered with a cover 12 which can be removed for service purposes.
- the rotary drive 6 for the support table 10 is designed in a known manner. Only for example, a drive screw 6 'is indicated schematically.
- the bearing 7 of the support table 10 is provided with a longitudinal bore 13 coaxial to the feed axis XX in order to allow the rod material to be bent to pass freely from the straightening rolls to allow set 5 to the bending head 9.
- the cutting device 8 is also designed in a known manner and is located directly in front of the bending head 9 in order to be able to produce extremely short end legs of the stirrups. By arranging the cutting device 8 on the rotatable support table 10 and in the feed axis X-X, the cutting device 8 can quickly separate the finished bracket from the material strand without additional positioning effort.
- the bending head 9 has a in a guide 9 'movable bending head plate 14 on which a fixed mandrel 15 and a pivot pin 16 for bending the rod are arranged.
- a fixed mandrel 15 and a pivot pin 16 for bending the rod are arranged.
- differently designed bending tools can also be used.
- the support table 10 has a table surface 10 ', which is at least as large as the area delimited by the outline of the bracket to be manufactured and defines the bending plane. In all positions of the support table 10 with the table surface 10 facing upwards, the support table supports the brackets during the bending process. In the case of particularly large stirrups, the support table 10 forms a support for the stirrups together with the frame 3.
- a two-part contact strip 17, which is only shown schematically, is also arranged at a distance from the bending head, which controls the rotary movement of the support table 10 and thus the position of the bending plane in space when electrically making contact with the element to be produced, etc. also during bending, for example, when the element emigrates from the bending plane, to adjust the table surface 10 'of the support table 10 in renewed contact with the element and thus to ensure the production of flat brackets.
- FIG. 1 shows an agreement adjustment of bending level and feed level, which is to be regarded as the basic setting.
- Fig. 2a only a small deviation between the bending plane and the feed plane is shown, which e.g. in the production of entangled temples due to the inclined table surface, a deliberate overcompensation in the bending and a counter-deformation of the rod material causes and thus prevents an undesirable gaping of the temple legs in the finished temple.
- the support table 10 is rotated out of the basic position according to FIG. 1 to such an extent that the support table 10 is arranged almost horizontally with the table surface facing downward. Since in this position the bending tools 15, 16 point downwards, it is possible, for example, to drop bracket B without an additional collecting device in the vertical direction P 3 onto a storage device 18, for example a rotary plate.
- the turntable 18 is rotatable according to the double arrow P4 to allow an orderly stacking of the bracket B.
