Definitions
- the invention relates to a device for producing hollow sections according to the preamble of claim 1 and a method for producing hollow sections according to the preamble of claim 9.
- Devices for producing hollow profiles in which hollow sections are produced in a plurality of steps taken independently of one another, for example for loading, deformation and unloading.
- the disadvantage is that in these known methods in particular interruptions or an intermediate settling of the board takes place, so that in each case an adjustment must be made and an accurate alignment of the boards.
- the object of the present invention is to provide a quick and secure deforming device.
- an apparatus for producing hollow profiles, in particular tubes comprising a bending device for bending a circuit board, in particular a welding device for closing a longitudinal seam of the hollow profile, in particular of the tube, a transport device for loading a circuit board, a transport device for unloading the hollow profile, a punch tool and at least one die tool for forming the hollow profile, wherein the punch tool and the die tool are provided longitudinally displaceable in the axial direction.
- a side slide in particular a respective side slide on opposite sides of the device, are provided for the radial addition of the hollow profile.
- the punch tool is at the same time to be used as a transport device for unloading the hollow profile, in particular by pushing out the hoof profile with one end of the punch tool and / or the shaped hollow profile is held in a region of the upper die tool by means of a holding device and can thus be transported out ,
- the transport device for loading a circuit board suction device which are arranged in particular laterally of the stamping tool.
- the T-insert can be used as a holding device for the finished shaped hollow profile.
- the side slides can be moved out of a tool closing area.
- a method for producing hollow profiles, in particular tubes wherein a device for producing hollow profiles, in particular according to one of claims 1 to 8, a board is loaded into a bending device for a hollow profile, with a punch tool in one Submatrix tool is bent, the punch tool in the axial direction is moved out of a bending region such that an axially coupled thereto upper die tool above the Untermatrizentechnikmaschines is arranged and thus the further deformation is performed.
- a transport device for loading a board picks up a board and loads the bending device in the area of the lower die tool by moving the stamping tool back in the axial direction, wherein in particular one end of the stamping tool and / or a holding device arranged in the area of the upper die tool removes the shaped hollow profile from the lower die tool.
- FIG. 1 shows a device for producing hollow profiles, in particular tubes, with inserted board
- FIG. 2 shows a device for producing hollow profiles, in particular tubes with stamping tool
- Fig; 3 a device for producing hollow profiles, in particular tubes, with stamping tool
- 4 shows a device for producing hollow profiles, in particular tubes, with the punch tool pulled out
- 5 shows a device for producing hollow profiles, in particular tubes, with displaced stamping tool
- FIG. 6 shows an apparatus for producing hollow profiles, in particular tubes, with shaping in upper die
- FIG. 7 shows a device for producing hollow profiles, in particular tubes, with shaping in upper die
- FIG. 8 shows a device for producing hollow profiles, in particular tubes, with shaping in upper die
- FIG. 9 shows a device for producing hollow profiles, in particular tubes, with shaping in upper die
- Fig. 14 shows an apparatus for producing hollow sections, in particular pipes, with preparation of a new board
- Fig. 15 shows an apparatus for producing hollow profiles, in particular pipes, with preparation of a new board.
- a bending device 3 has a stamping tool 6 which can be exchanged for different diameters.
- the bending device 3 has a sub-die tool 12 into which the stamping tool 6 is pressed.
- the bending device also has an upper die tool 9, through which, after the lower part of the blank 2 has been formed, the upper part of the blank is also formed into the tube 5.
- the Matrizentechnikmaschinehalter are provided at the top and bottom, which in particular are changeable depending on the required diameter.
- the bending device 3 has a press with a predetermined pressure force for O-forming a tube 5 from the circuit board 2.
- FIG. 2 shows an apparatus for producing hollow profiles, in particular tubes 5, with stamping tool 6.
- the stamping tool 6 in particular a bending punch
- the blank 2 is inserted into the sub-die tool 12 via round ends 14 of side slides 10, which are preferably arranged on both sides 11 , in particular a bending die pressed, so that a U-shape is formed.
- Fig. 3 shows an apparatus for producing hollow sections, in particular tubes 5, with punch tool 6.
- the plunger tool 6 airs and the side gate 10 bend the already deformed to a U board 2 to a U. with inwardly inclined sides 13 together.
- FIG. 4 shows an apparatus for producing hollow profiles, in particular tubes 5, with the punch tool 6 pulled out.
- the punch tool 6 is in position so that tool tops, in particular the punch tool 6 and an upper die tool 9 coupled, can be changed in the axial direction 8.
- Fig. 5 shows an apparatus for producing hollow sections, in particular tubes 5, with displaced punch tool 6.
- the punch tool 6 and the upper die tool 9 change their position in the axial direction 8 as soon as the press stroke has reached a predetermined height.
- This procedure can also be used as a push-out buffer. This allows a UO bending of a tube blank in a single very compact, narrow press done. Carried a tool 'tool change must in particular only in Obermatrizentechnikmaschinemaschine 9 whereby collisions and complex movements are avoided.
- 6 shows a device for producing hollow profiles, in particular tubes 5, with shaping in upper die tool 9. The side slides 10 are pushed together to attach the tube blank.
- FIGS. 7 and 8 show an apparatus for producing hollow profiles, in particular tubes 5, with shaping in upper die tool 9.
- the upper die tool 9 continues the closing operation until pipe ends 15 move around the upper die tool 9.
- FIG. 9 shows a device for producing hollow profiles, in particular tubes 5, with shaping in upper die tool 9.
- the side slides 10 move out of a tool closing region 16, so that a complete closure can take place.
- the O-formation of the tube 5 takes place.
- a T-insert can advantageously be used, which also holds the slot in position and prevents it from possibly becoming spirally deformed.
- a pure O-shaping of the plate 2 takes place between the two matrices.
- the tube 5 is formed along the contour, it may happen - if the board length is greater than the theoretical tube circumference, a compression of the material, which is advantageous for the quality of the tube in terms of roundness and strength increase. In the latter case, the tube 5 can be held in the half-shell of the upper die tool 9 with staples or similar aids
- FIG. 1 1 shows an apparatus for producing hollow profiles, in particular tubes 5, with preparation of a new board 2.
- a new board 2 is in a transport device 4, for example by suction 17 or similar transfer tool, in particular laterally from the punch tool 6 ⁇ orders, recorded.
- 12 shows a device for producing hollow profiles, in particular tubes 5, with preparation of a new board 2.
- Fig. 13, 14, 5 show an apparatus for producing hollow sections, in particular tubes 5, with preparation of a new board 2.
- the board 2 is located on side slides 0 above the lower die tool 12. Here is also the exact center alignment, for example, at anchor points of Side slide 10.
- the bent tube blank is deported into a welding machine, By the welding method, in particular laser welding or another suitable method, the tube is closed, in particular the slot in the tube blank or the flush-fitting tube ends after bending.
