Definitions
- the invention relates to a folding machine for the automated or semi-automated forming of sheet metal workpieces that are planar in the initial state.
- a disadvantage of the designs known from the prior art is that small-format workpieces can only be fed to the central section of the workpiece holding unit with relatively great effort by an operator in the case of support tables with a large surface area.
- the folding machines known from the prior art have the disadvantage that feeding small-format workpieces is not very ergonomic for an operator and proper positioning and exact referencing of a workpiece to be machined can be difficult for an operator.
- the object of the present invention was to overcome the disadvantages of the prior art and to provide technical means by means of which even small-format workpieces can be fed in and positioned exactly without any particular effort for an operator.
- the swivel bending machine according to the invention includes
- a workpiece holding unit connected to the machine frame with a first clamping tool and an adjustable second clamping tool cooperating with this for fixing a workpiece in a horizontal working plane in such a way that a workpiece section to be bent can protrude in relation to the workpiece holding unit;
- a bending beam which is adjustably mounted on the machine frame and is connected to an adjusting drive, for bending the workpiece section;
- a workpiece manipulator which is set up to pick up workpieces to be bent starting from at least one of the table end regions and bring them parallel to the longitudinal direction of the bending beam into a section in the region of the longitudinal center of the workpiece holding unit, the workpiece manipulator having a first clamping tongs and one in the longitudinal direction of the bending beam second clamping tongs spaced therefrom for establishing a clamping connection with respect to a workpiece, and wherein at least the first clamping tongs have a first stop surface for referencing a workpiece in relation to the longitudinal direction of the bending beam and a second stop surface for referencing this workpiece in relation to the depth direction of the folding machine.
- a referencing of the workpiece is to be understood as meaning the positioning or alignment of the workpiece in relation to a zero or reference point provided by the operating control of the folding machine.
- a zero or reference point for a workpiece to be machined can also be referred to as the starting point, which typically lies within the working plane.
- the swivel bending machine according to the invention offers the advantage that an operator can feed a workpiece to be machined to the workpiece manipulator from one of the two side areas of the support table and the workpiece can then be automatically transferred to the central section of the tool holding unit.
- This enables the operator to feed the workpieces ergonomically, both with small-format and relatively heavy workpieces.
- an operator can always feed a workpiece to the specified workpiece manipulator precisely and easily so that it can be checked, because the first and the second clamping tongs can be easily viewed and reached by an operator.
- the assumption of the planned reference position by the workpiece to be bent can be checked quickly and easily by the operator.
- the workpiece manipulator can be moved into and out of the inner region of the bending beam enclosed by the C-shaped beam cross-section by means of a guide arrangement running parallel to the longitudinal direction of the bending beam.
- a guide arrangement running parallel to the longitudinal direction of the bending beam.
- a simple adjustability of the workpiece manipulator in the vertical or height direction can be achieved by a movement coupling with the bending beam.
- the workpiece manipulator can be moved by means of the guide arrangement beyond at least one longitudinal end of the bending tools. This makes it easier for an operator to see the two clamps and in particular their stop surfaces.
- first and the second clamping tongs are each fastened on a translational adjusting axis and these adjusting axes are provided for the controlled positioning of the first and second clamping tongs along the depth direction of the folding machine.
- a workpiece to be bent can be positioned quickly and technically reliably in relation to the depth direction of the folding machine.
- first and the second clamping tongs each comprise a pneumatically actuable actuating cylinder for closing the respective clamping tongs.
- This enables the clamping effect to be activated in relation to a workpiece alternately or independently of one another. Accordingly, it is possible to use the clamping effect of only one of the two clamps. Pneumatic actuation of the clamping tongs offers a good compromise between technical simplicity, economy and functional availability.
- first and second clamping pliers each have a wedge-shaped tapering actuating section, and that an actuating piston that can be extended from the actuating cylinder and has a spreading effect can be inserted into the actuating portion.
- first and the second adjusting axis each have an electric motor and each to have a threaded spindle coupled to the electric motor for the translatory adjustment of the first and second clamping tongs.
- first or the second clamping tongs or the first and the second clamping tongs are set up to grip a side edge of a workpiece which runs parallel to the longitudinal direction of the bending beam and is arranged next to the bending beam.
- the rear boundary edge of a workpiece so to speak, in relation to the location of a user and in relation to the depth direction of the folding machine, is used for clamping and referencing. This favors the ergonomics and also the visibility towards the workpiece manipulator.
- an operator can achieve quick, uncomplicated and repeatable positioning and transfer processes in relation to the workpiece manipulator.
- the first stop surface which is provided for referencing or for referencing positioning of a workpiece in relation to the longitudinal direction of the bending beam, runs vertically and transversely to the longitudinal direction of the bending beam and outside of a clamping section of the first and second clamping tongs is positioned.
- the first and second stop faces for the planned positioning and alignment of a workpiece to be machined are formed directly on the first and second clamping tongs. It is expedient here if the first stop surfaces for the relative positioning of a workpiece in relation to the longitudinal direction of the bending beam are formed on the pivotably mounted clamping fingers of the first and second clamping tongs.
- the second stop surfaces for the relative positioning of a workpiece in the depth direction of the swivel bending machine are preferably formed on the support fingers of the first and second clamping tongs which are stationary in relation to the swiveling clamping fingers.
- the workpiece manipulator it is possible for the workpiece manipulator to be set up to use the first stop surface for referencing a workpiece in the longitudinal direction of the bending beam with only one of the two clamping tongs and only increase the clamping effect on this workpiece with the other of the two clamping tongs to use.
- one of the clamping tongs for example the first clamping tongs, ensures referencing with respect to the control-related zero point, and the other, for example the second clamping tongs, clamps or holds the workpiece.
- a support body of an additional manipulator protrudes in the vertical direction from a table level of the support table, which additional manipulator has a rotary punch that can be rotated about a vertical axis for rotating workpieces to be machined about the vertical axis, and that the support body is in the longitudinal center or in the Area of the longitudinal center of the support table towers vertically.
- workpieces on which bending edges running at an angle or at right angles to one another are to be produced can be automatically rotated around their vertical axis.
- the accessibility of the workpiece holding device, which is restricted by such an additional manipulator can be compensated for by the workpiece manipulator that can be positioned and loaded on one of the two longitudinal sides of the support table.

- the front side 18 of the workpiece holding unit 3 is the side of the workpiece holding unit 3 facing away from the bending beam 8. Accordingly, the supporting table 17 and the bending beam 8 arranged oppositely with respect to the workpiece holding unit 3 .
- the support table 17 has a table length 19 measured parallel to the longitudinal direction 12 of the bending beam 8 of more than 1.5 meters between its two table end regions 20, 21.
- the support table 17 has a table depth 22 measured parallel to the horizontal working plane 6 and perpendicular to the front side 17 of more than 1.0 meter.
- the depth direction 16 of the bending machine 1 is defined by the serial sequence of the support table 17, the workpiece holding unit 3 and the bending beam 8. Accordingly, the support table 17 has such a large horizontal surface area; that an operator can only reach the workpiece holding unit 7 or the edge of the support table 17 closest to the workpiece holding unit 7 with difficulty or see it relatively poorly.
- the support table 17 extends directly or essentially without a gap to the workpiece holding unit 3 . In particular, the supporting table 17 reaches so close to the workpiece holding unit 3 that it is not possible for an operator to find a space or enter therebetween.

- a maximum available adjustment path of the adjustment axes 35, 36 can only be between 30 mm and 100 mm, in particular about 50 mm.
- the first and second clamping tongs 25, 26 each have a pneumatically actuable actuating cylinder 37, 38 for closing the respective clamping tongs 25, 26.
- the adjusting cylinders 37, 38 can be designed as single-acting cylinders.
- the clamping tongs 25, 26 can each have a return spring 39, as can be seen from FIG.
- the first and second clamps 25, 26 each have an internal, wedge-shaped tapering actuation from section 40.
- One of the actuating cylinder 37, 38 extendable actuating piston 41 can be inserted with a spreading effect in the actuation from section 40 in order to activate the clamps 25, 26.
- Such an active clamping or closed position without a workpiece 2 is illustrated in FIG.
- the first and preferably also the second clamping tongs 25, 26 have a non-pivotable lower support finger 42, 43 and an upper clamping finger 44, 45.
- the upper clamping finger 44, 45 is pivotably mounted relative to the lower support finger 42, 43 about a horizontal pivot axis 46, 47.
- the first and the second adjusting axis 35, 36 each have an electric motor 48, 49 and a threaded spindle 50, 51 coupled to the electric motor 48, 49 for the translatory adjustment of the first and second clamping tongs 25, 26 along the depth direction 16 of the folding machine 1.
- the first and second clamping tongs 25, 26 are designed to grip the side edge 52 of a workpiece 2, which runs parallel to the longitudinal direction 12 of the bending beam 8 and is arranged closest to the bending beam 8.
- the first stop face 27 , 28 of the clamping tongs 25 , 26 is provided for referencing or for referencing positioning of a workpiece 2 in relation to the longitudinal direction 12 of the bending beam 8 .

- the rotary stamp 58 is mounted on a support arm which runs essentially horizontally The support arm extends from the support body 56 in the direction of the workpiece holding unit 3 .
- the support body 56 protrudes vertically in the longitudinal center 24 or in the region of the longitudinal center 24 of the support table 17 . This makes it difficult to load the bending machine 1 with workpieces 2 from that longitudinal side of the support table 17 which faces away from the workpiece holding unit 3 or is furthest away. This can be remedied by the work piece manipulator 23 described above.
