Abstract
Description
Technical Field
[0001] The invention relates to a forming machine having a forming station and having a cutting device for cutting rod segments from rods according to the preamble of independent patent claim 1, and a method for cutting rod segments from rods according to the preamble of independent patent claim 10. Background Art
[0002] In the prior art, multi-step forming machines with a plurality of forming stations are known, which are arranged one after another and have a cutting device for cutting off the rod segments from the rod. Such forming machines include in particular those whose cutting devices are not only used to cut off the rod segments from the rod, but also to feed the cut rod segments to the first forming station. DE 29 40 375 C2 discloses such a forming machine, wherein the cutting device comprises a cutting carriage that can be moved forward and backward and a cutting blade attached to the cutting carriage. With the cutting blade, in the first forward movement of the cutting carriage, the rod segments can first be cut off from the rod and then fed to the first forming station. The cutting carriage is driven by a double cam via a double roller lever. In this way, the positioning of the cut rod segments in the first forming station cannot be adjusted, and it is particularly impossible during continuous operation without stopping the machine. This is disadvantageous because, due to the cutting, the cut rod segments usually have an irregular geometry and the center of gravity is not always located on the axis of rotation. In order to obtain an optimal volume distribution in the first forming station, therefore, the cut rod segments should be positioned in the first forming station in an optimal manner. This can be achieved, for example, by adjusting the positioning using adjustment plates and adjustment screws, but this results in longer machine downtimes. This is even more problematic because in some cases the adjustment process must be repeated several times until the volume distribution in the first molding station is uniform.
[0003] Against this background, the problem underlying the invention is to provide a forming machine having a forming station and having a cutting device, and a method for producing rod segments cut off from a rod of the type mentioned at the outset, by means of which the position of the rod segments cut off from the rod and fed to the forming station can be adjusted in the forming station as optimally as possible in a simple manner, without having to completely stop the machine. Summary of the invention
[0004] This problem is solved by a forming machine according to the invention and a method according to the invention for cutting off rod segments as defined in the independent patent claims 1 and 10. Particularly advantageous developments and embodiments are evident from the dependent patent claims.
[0005] The core of the invention is as follows: the forming machine has a forming station and a cutting device for cutting off a rod segment from a rod material and feeding the cut rod segment to the forming station. The cutting device comprises a cutting bracket that can be moved forward and backward and a cutting blade attached to the cutting bracket. With the cutting blade, the rod segment can be cut off from the rod material and fed to the forming station during the forward movement of the cutting bracket. The cutting device comprises a device for adjusting the stroke and forward movement direction of the cutting bracket.
[0006] In the present context, "rod" is to be understood as any form of material having a distinct longitudinal length and any desired cross section, the cross section generally remaining constant over the longitudinal length. Rods, bars and wires of metal of any size fall particularly under this definition. A circular cross section is the rule, but the invention is not limited thereto. The rod may extend in a straight line or may also be rolled up.
[0007] “Moveable forward and backward” includes movement in horizontal, vertical or inclined spatial directions.
[0008] Since the cutting device comprises means for adjusting the stroke and the direction of the forward movement of the cutting carriage, the position of the rod segments cut off from the rod and fed to the forming station can be optimally adjusted in a simple manner in the forming station. This saves time considerably and reduces machine downtimes compared to the prior art.
[0009] Advantageously, the means for adjusting the stroke and the forward movement direction of the cutting carriage are configured such that they can adjust the stroke and the forward movement direction of the cutting carriage during continuous operation of the forming machine, the forming machine preferably comprising a control unit for controlling the means for adjusting the stroke and the forward movement direction of the cutting carriage.
[0010] Being able to adjust the stroke and the forward movement direction of the cutting carriage during continuous operation of the forming machine means that a complete stop of the machine can be avoided during adjustment of the positioning of the cut-off rod segments in the forming station. This saves a great deal of time and reduces machine downtime compared to the prior art.
[0011] A control unit for controlling the means for adjusting the stroke and the forward movement direction of the cutting carriage allows simple operation of these means and, if necessary, automation.
[0012] Advantageously, the cutting device comprises a variable stroke cutting carriage driver, by which the cutting carriage can move forward and backward. By this cutting carriage driver, the adjustment of the forwardly moving stroke of the cutting carriage can be realized in a simple manner.
[0013] The cutting carriage drive is preferably independent of the drives of the forming tools in said forming station and in any other forming station of the forming machine.
[0014] Preferably, the cutting carriage drive comprises a hydraulic cylinder and a piston displaceable in the hydraulic cylinder, the piston being connected to the cutting carriage via a piston rod.By such a cutting carriage drive, a variable stroke controllable by a control unit can be easily realized.
[0015] Advantageously, in order to adjust the forward movement direction of the cutting carriage, the cutting carriage can be pivoted about a pivot axis.The pivoting of the cutting carriage allows a simple adjustment of the movement direction.
[0016] Preferably, the cutting carriage is movable forwards and backwards transversely relative to the longitudinal direction of the wand segment, and the pivot axis extends parallel to the longitudinal direction of the wand segment.
[0017] The fact that the cutting carriage can be moved forwards and backwards transversely to the longitudinal direction of the rod segment means that, during the forward movement of the cutting carriage, the rod segment can be cut off from the rod material along a straight line transversely to the longitudinal direction of the rod segment and the cut rod segment can then be fed to the forming station in the same step.
[0018] Since the pivot axis of the cutting carriage extends parallel to the longitudinal direction of the rod segment, the positioning of the cut rod segment in the forming station can be adjusted in a plane perpendicular to the pivot axis of the cutting carriage and the longitudinal direction of the rod segment. Together with the variable stroke of the cutting carriage, this allows a specific positioning of the cut rod segment in the forming station within this plane.
[0019] Advantageously, the cutting carriage is guided in a cutting carriage bearing which is at least to some extent pivotable about a pivot axis.Thus, the pivoting of the cutting carriage and the adjustment of the forward movement direction of the cutting carriage can be achieved by means of the cutting carriage bearing.
[0020] Preferably, the means for adjusting the stroke and the forward movement direction of the cutting carriage comprises a pivot angle adjustment device which acts eccentrically on the cutting carriage bearing and adjusts the pivot angle of the cutting carriage bearing during adjustment, the pivot angle adjustment device preferably comprising an eccentric wheel. Such a pivot angle adjustment device enables the adjustment of the pivot angle of the cutting carriage bearing and the forward movement direction of the cutting carriage in a simple manner.
[0021] In a preferred embodiment, the cutting carriage bearing is connected to the at least one static attachment part via at least one elastically deformable connecting part. In this way, maintenance work can be reduced, since no high-maintenance hinges are required.
[0022] Regarding this method, the core of the present invention is as follows:
[0023] In a method for cutting off a rod segment from a rod material and supplying the cut rod segment to a forming station of a forming machine, a cutting device includes a cutting bracket that can be moved forward and backward and a cutting blade attached to the cutting bracket. By the cutting device, the cutting blade cuts off the rod segment from the rod material during the forward movement of the cutting bracket and supplies the rod segment to the forming station. In order to position the cut rod segment in the forming station, the stroke and forward movement direction of the cutting bracket are adjusted.
[0024] The adjustment of the stroke and the forward movement direction of the cutting carriage enables the position of the rod segments cut off from the rod and fed to the forming station to be adjusted optimally in a simple manner in the forming station. Compared with the prior art, this saves time and reduces machine downtimes. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following remarks apply to the following descriptions: Where, for the sake of clarity, reference numerals are included in a drawing but are not mentioned in a directly relevant part of the description, reference should be made to the explanation of these reference numerals in the preceding or succeeding part of the description. Conversely, in order to avoid over-complication of the drawings, reference numerals that are not directly relevant to the understanding are excluded from all drawings. In such cases, reference should be made to other drawings.
[0039] Figure 1 is a partially cross-sectional and partially schematic perspective view of a portion of an exemplary embodiment of a forming machine 100 according to the invention, in this case a multi-step forming machine. The forming machine 100 comprises a machine body 90 in which a plurality of successive forming stations 91, 92, etc. for gradually forming workpieces are arranged in a known manner. In the successive forming stations, Figure 1 Only the mold side portion of the first molding station 91 and a part of the mold side portion of the molding station 92 can be seen.
[0040] The forming machine 100 further comprises a cutting device 1 which is also attached to the machine body 90 and by means of which workpieces can be cut from the bar material, said workpieces being formed in the first forming station 91 in the form of bar segments W and fed to the first forming station 91. The bar material here consists of a metal bar which is formed from Figure 1The rod section W visible in the figure extends obliquely backwards, but apart from the rod section W, the metal rod is completely hidden by the machine parts of the forming machine.
[0041] The cutting device 1 comprises a cutting carriage bearing 5 extending through a cylindrical opening of a machine body 90, in which a cutting carriage 2 is mounted so as to move forward and backward in a longitudinal direction. In a subregion of the cutting carriage bearing 5, a sliding bushing 50 is arranged between the cutting carriage 2 and the cutting carriage bearing 5, which supports the cutting carriage 2 so as to facilitate sliding.
[0042] like Figure 5 and Figure 6 As can be best seen in FIG. 1 , the cutting carriage bearing 5 has a hollow cylindrical body 51 which is provided on the upper side with a groove 52 extending in the longitudinal direction. The hollow cylindrical body 51 is connected to two attachment parts 58 and 59 by two connecting parts 56 and 57, respectively. The hollow cylindrical body 51, the two connecting parts 56, 57 and the two attachment parts 58, 59 are formed as a single piece. The cutting carriage bearing 5 is screwed to the machine body 90 via the two attachment parts 58, 59 by means of screws 581, 582, 591, 592, see in particular Figure 1 , 3 , 4 and 7, and is therefore fixed and static on one side. The hollow cylindrical body 51 can be pivoted through a small angle relative to the stationary part of the cutting carriage bearing 5. Figure 1 and Figure 2 As shown, the pivot axis A extends through relatively thin elastically deformable connecting parts 56, 57. The elastic deformability means that a high maintenance hinge is not required.
[0043] In order to pivot the hollow cylindrical body 51 about the pivot axis A, the cutting device 1 has a pivot angle adjustment device 6. Figures 1 to 4As can be seen in particular, the pivot angle adjustment device 6 comprises a servomotor 61, by means of which a drive shaft 63 with an eccentric disc 64 can be rotated via a gear mechanism 62, in particular a worm gear. The drive shaft 63 is arranged in a housing 67, which is attached to the machine body 90 via an attachment plate 68. The eccentric arm 65 is connected to the eccentric disc 64 via one eccentric arm end 651 and is hinged to an adjustment collar 66 via its other eccentric arm end 652, which is connected to the end region of the hollow cylindrical body 51 of the cutting carriage bearing 5 and is arranged around the latter. The drive shaft 63, the eccentric disc 64 and the eccentric arm 65 together form an eccentric wheel. The rotation of the shaft 63 and the eccentric disc 64 displaces the eccentric arm 65 connected to the eccentric disc 64 at the eccentric arm end 651, which in turn affects the translational displacement of the adjustment collar 66 connected to the cutting bracket bearing 5, thereby raising or lowering the end region of the hollow cylindrical body 51 of the cutting bracket bearing 5 connected to the adjustment collar 66. This causes the hollow cylindrical body 51 to pivot about the pivot axis A, or adjust the cutting bracket bearing 5 or the pivot angle α of the hollow cylindrical body 51 of the cutting bracket bearing 5, which pivot angle is as shown in FIG. Fig.10 and Fig.12 as shown in .
[0044] Reference Fig.10 The pivot angle α can be defined as the angle between the longitudinal direction g of the hollow cylindrical body 51 of the cutting bracket bearing 5 when it is pivoted around the pivot axis A and the longitudinal direction a of the hollow cylindrical body 51 of the cutting bracket bearing 5 when it is not pivoted relative to the static part of the cutting bracket bearing 5. Fig.10 The longitudinal direction g shown in FIG. 5 is the center axis of the hollow cylindrical body 51 of the cutting bracket bearing 5 . Figure 2 The non-pivoted state of the hollow cylindrical body 51 of the cutting carriage bearing 5 is shown. The longitudinal direction a shown therein corresponds to the center axis of the hollow cylindrical body 51 of the cutting carriage bearing 5.
[0045] The pivot angle α is adjustable in the range of -20° to 20°. Preferably, the shaping machine is dimensioned such that an adjustment range of -10° to 10°, more preferably -5° to 5°, is sufficient.
[0046] If you can Figure 1 , 3 As best seen in Figures 4 and 5, the cutting carriage 2 mounted in the cutting carriage bearing 5 has a cylindrical body 21 from which a lug 22 extends upwardly away. The lug 22 engages in a groove 52 of the hollow cylindrical body 51 of the cutting carriage bearing 5 and thus forms an anti-rotation device together therewith.
[0047] The cutting head 3 is attached to the cutting carriage 2 on its side facing the first forming station 91, and has a cutting blade 30, which is open on the side facing the first forming station 91 and abuts against the rod segment W. The rod segment W is pressed against the cutting blade 30 from the other side by a segment holder 31 mounted on a rotatable rod 32, which serves to hold the rod segment W against the cutting blade 30 after it is cut off from the rod material, and to transport the rod segment thus held to the first forming station 91. Cutting off the rod segment W from the rod material and transporting or supplying the cut rod segment to the first forming station 91 are achieved by the forward movement of the cutting carriage 2 with the cutting head 3 and the cutting blade 30 in the direction toward the first forming station 91. The rotatable rod 32 with the mounted segment holder 31 operates in such a way that, as soon as the rod segment W to be cut off is placed in front of the cutting blade 30 by the advancement of the rod material, it presses the rod segment W against the cutting blade and keeps the cutting blade 30 pressed against the rod segment until the cut rod segment is fed to the first forming station 91 and taken over by the holding device therein. Everything described in this paragraph and the details of how it is implemented are known to the person skilled in the art and are fully described in DE 29 40 375 C2, the disclosure of which is therefore expressly incorporated herein by reference. The person skilled in the art does not need further explanation in this regard.
[0048] In order to move the cutting carriage 2 forward and backward, the cutting device 1 has a variable stroke cutting carriage drive 4. The cutting carriage drive 4 comprises a hydraulic cylinder 41 and a piston 42 movable in the hydraulic cylinder 41, and the piston 42 is connected to the cutting carriage 2 via a piston rod 43. Figure 1 As shown schematically, the hydraulic cylinder 41 is connected to a reservoir 46 through a hydraulic line 44 and a hydraulic line 45, the mouth of the hydraulic line 44 being behind the piston 42 and the mouth of the hydraulic line 45 being in front of the piston 42. By supplying hydraulic fluid from the reservoir 46 via the hydraulic line 44 behind the piston 42 and discharging the hydraulic fluid via the hydraulic line 45, the cutting carriage 2 moves forward in a direction toward the first molding station 91, while by supplying hydraulic fluid from the reservoir 46 via the hydraulic line 45 in front of the piston 22 and discharging the hydraulic fluid via the hydraulic line 44, the cutting carriage 2 moves backward away from the first molding station 91. The stroke of the cutting carriage 2 can be adjusted by controlling the amount of hydraulic fluid supplied.
[0049] In order to control both the cutting carriage drive 4 and the pivot angle adjustment device 6, the forming machine 100 has a control unit 7, such as Figure 1The control unit 7 allows simple operation of both the cutting carriage drive 4 and the pivot angle adjustment device 6, for example via an input unit 70, with which the desired stroke of the cutting carriage 2 and the desired direction of the forward movement of the cutting carriage 2 or the desired pivot angle α of the cutting carriage bearing 5 or directly the desired positioning of the rod segment W in the first forming station 91 can be input. If desired, extensive automation can be carried out via the control unit 7.
[0050] As previously mentioned, the cutting carriage 2 is mounted in the cutting carriage bearing 5 so as to move forward and backward in the longitudinal direction. When doing so, it is guided by a sliding bushing 50 which is arranged in a sub-region of the cutting carriage bearing 5 between the cutting carriage 2 and the hollow cylindrical body 51 of the cutting carriage bearing 5, see in particular Figure 1 As a result, the longitudinal direction in which the cutting bracket 2 moves back and forth corresponds to the longitudinal direction g of the hollow cylindrical body 51 of the cutting bracket bearing 5. The cutting bracket 2 has the same pivot axis A and the same pivot angle α as the hollow cylindrical body 51 of the cutting bracket bearing 5.
[0051] The pivot axis A preferably extends parallel to the longitudinal direction of the rod segment W to be cut off, and the cutting carriage 2 is preferably movable transversely to the longitudinal direction of the rod segment W forward and backward.
[0052] Figure 2 The non-pivoted state of the hollow cylindrical body 51 of the cutting carriage bearing 5 is shown. The pivot angle α is 0. The longitudinal direction a shown in the figure corresponds to the center axis of the hollow cylindrical body 51 of the cutting carriage bearing 5 and to the longitudinal direction and the center axis of the cutting carriage 2. The eccentric disc 64, the eccentric arm 65 and the adjustment collar 66 are located in a central position, as can also be seen from detail 2B. According to detail 2A, the piston 42 is almost at the left edge of the hydraulic cylinder 41, that is, almost in its position moved farthest backward. According to detail 2C, the cutting blade 30 is in contact with the rod segment W that has not yet been cut, which is held on the other side by the segment holder 31.
[0053] As a result of the movement of the piston 42 in the hydraulic cylinder 41 in the longitudinal direction a, the cutting carriage 2 moves forward in this direction, so that the rod segment W is cut off from the rod and conveyed or fed to the first forming station 91. Figure 7 and Figure 8 The state shown, in which the rod segment W is positioned in the center of the first forming station 91 according to detail 8C. According to detail 8A, the piston 42 is located near the right edge of the hydraulic cylinder 41, but can still be moved further to the right. Details 8A and 8C show the middle stroke of the cutting carriage 2. The eccentric disc 64, the eccentric arm 65 and the adjusting collar 66 are not displaced but remain in the center position, see also detail 8B.
[0054] Fig. 9 and Fig.10 A different situation is shown, in which the rod segment W according to detail 10C is in a position displaced towards the upper right in the first forming station 91. On the one hand, this is achieved by increasing the stroke, the piston 42 being moved further to the right compared to detail 8A, which can be seen in detail 10A. The piston 42 here even covers part of the mouth of the hydraulic line 45 entering the hydraulic cylinder 41. The stroke is increased by a distance h1, here about 1.5 mm.
[0055] According to detail 10B, the upward displacement of the rod segment W in the first forming station 91 is achieved by rotating the drive shaft 63 counterclockwise by an angle γ, which in turn causes the eccentric disc 64 to rotate therewith and pull the eccentric arm 65 and the adjustment collar 66 downwards, which in turn causes the hollow cylindrical body 51 of the cutting carriage bearing 5 to pivot downwards by a pivot angle α relative to the pivot axis A. Therefore, on the left side of the pivot axis A, the cutting carriage 2 is also pivoted downwards by a pivot angle α, and on the right side of the pivot axis A, it is pivoted upwards by a pivot angle α.
[0056] Fig.11 and Fig.12 Different situations are shown in sequence, in which the rod segment W according to detail 12C is in a position displaced to the left and downward in the first forming station 91. On the one hand, this is achieved by reducing the stroke, the piston 42 is moved further to the left compared to detail 8A, which can be seen in detail 12A. The piston 42 enters the hydraulic cylinder 41 further away from the mouth of the hydraulic line 45. The stroke is reduced by a distance h2, here about 1.5 mm.
[0057] According to detail 12B, the downward displacement of the rod segment W in the first forming station 91 is achieved by rotating the drive shaft 63 clockwise through an angle γ, which in turn causes the eccentric disc 64 to rotate therewith and push the eccentric arm 65 and the adjustment collar 66 upwards, which in turn causes the hollow cylindrical body 51 of the cutting carriage bearing 5 to pivot upwards through a pivot angle α relative to the pivot axis A. Therefore, on the left side of the pivot axis A, the cutting carriage 2 is also pivoted upwards through a pivot angle α, and on the right side of the pivot axis A, it is pivoted downwards through a pivot angle α.
