Definitions
- the invention relates to a counter-holding device for a bending machine, in particular for a pipe bending machine, in the form of a slide rail which is moved linearly during the bending process and has a plurality of slide rail attachments for different bending radii.
- the object of the invention is to improve a counter-holding device for a bending machine of the type mentioned at the outset in such a way that the risk of collision between sliding rail attachments and tool parts is avoided.
- the invention achieves the stated object with a counter-holding device of the type mentioned at the outset in that the slide rail attachments are mounted on the slide rail via lockable and unlockable adapters.
- the slide rail attachments in particular those for the small radii, can be uncoupled from the common drive of the slide rail attachments, thereby avoiding a collision of the slide rail attachments, in particular those for the small radii, with clamping jaws or other tool parts.
- the adapters can be programmable via an NC control or can be locked and unlocked automatically.
- the slide bar attachments and adapters can form a retrofit unit.
- the several slide rail attachments can be aligned with the height of the several bending tools, the height of the multiple slide rail attachments and adapters can be adjusted separately.
- the invention also relates to a bending machine, in particular a tube bending machine with a clamping device for a workpiece to be bent, in particular a tube, a bending head provided with a plurality of bending tools having different radii and a plurality of bores that can be moved horizontally and / or vertically to the longitudinal axis of the workpiece and with which Bending tools cooperating swivel arm having jaws, which has a counter-holding device according to the invention.
- a bending machine in particular a tube bending machine with a clamping device for a workpiece to be bent, in particular a tube, a bending head provided with a plurality of bending tools having different radii and a plurality of bores that can be moved horizontally and / or vertically to the longitudinal axis of the workpiece and with which Bending tools cooperating swivel arm having jaws, which has a counter-holding device according to the invention.
- Figure 1 is a schematic view of a bending machine with a counter-holding device according to the invention.
- FIG. 2 shows a side view of the counter-holding device of the bending machine from FIG. 1.
- a bending machine 10 with a machine body 16 and a bending head 17.
- a pipe not shown here, to be bent can be clamped in a clamping device 11.
- a slide rail 12 has the task of supporting and tracking the pipe during the bending process.
- slide rail attachments 20, 22, 23, 24 (FIG. 2) are arranged.
- the movement of the slide rail 12 must take place during the bending process synchronously with the bending movement of a clamping block 13 with clamping jaws 18, which is mounted on a swivel arm 14.
- the tube is bent over a corresponding bending tool 15.
- FIG. 2 shows the slide rail 12 from FIG. 1 in an enlarged view, on which the four slide rail attachments 20, 22, 23, 24 are mounted lockable and unlockable via adapter 21.
- Locking and unlocking can be done via the NC control of the machine for reasons of easy handling or automatically.
- the slide rail attachment 20 for smaller bending radii can be uncoupled from the slide rail. In this way, a collision between the slide rail attachment 20 and the clamping jaws 18 shown in FIG. 1 can be avoided.
