Definitions

  • the invention relates to a device for manipulating workpieces, in particular metal sheets, in front of, in and behind the plane of movement of a tool of a press, in particular a press brake with at least one transport slide and at least one pair of pliers.
  • a device for manipulating workpieces in a press room of a forging press has become known.
  • the lifting slide has a pliers slide with at least one manipulating pliers and at least one adjusting rack which is driven by a pinion arranged on the vertical spindle, while the manipulating pliers are actuated by an actuating cylinder piston arrangement.
  • This device is suitable for special machining of workpieces such as forging, drop forging or punching.
  • the disadvantage of this device is that the manipulation pliers place the workpiece for processing in the press room and are outside the press room during the working stroke and the workpiece has to be grasped again for each subsequent manipulation for further processing.
  • Another DE-AS 28-47 543 discloses a loading and unloading device for presses or similar machine tools, which has the task of lifting a workpiece from a stacking place, placing it in the press room of a press or a punch, in order to remove it from the die after processing pick up again and put down on a stack.
  • a part of a parallelogram linkage which is controlled via a crank arm and a corresponding cam disc, serves as the transport arm.
  • the device is also suitable for loading presses or punches in which the workpiece is being machined while the loading device is located outside the press room.
  • the disadvantage of the known device is also that the workpiece has to be re-gripped for each changeover or unloading.
  • the invention has for its object a manipulation to propose device for presses, in particular press brakes, which makes it possible, above all heavy and bulky workpieces, for example heavy and large metal sheets, which a single worker can no longer move, or only very difficultly, without tools, automatically and in a time-saving manner in all Bring necessary positions, which are required for a different type of folding, for example, with same-sided folds on the same sheet metal side, or opposite-sided folds on the opposite sheet metal side, without the pliers having to leave the sheet metal sheets between the individual processing sequences.
  • the advantages achieved by the invention are essentially to be seen in the fact that, for example, heavy and unwieldy metal sheets for loading a press brake, for manipulations and changes for edging and possibly for carrying away the machined workpieces without human effort, can be repeated precisely without unnecessary loss of time can be moved automatically, and that individual elements can be assigned to the basic version of the device, both on the feeder side and on the discharge side, the number of which can be expanded as required.
  • FIG. 1 denotes a press brake with a ram 2, a tool stamp 3, a die 4 and a work table 5.
  • Parallel to the tool stamp 3, horizontal guides 6 for a horizontal slide 7 are arranged on the press brake.
  • a rack 8 is used for the back and forth movement of the horizontal slide 7.
  • 10 denotes a vertical slide which slides in vertical guides 9 arranged on the horizontal slide and can be moved up and down by a pinion 12 on a rack 11 also arranged on the horizontal slide .
  • an axis 13 carries a tiltably mounted bracket 15, which can be tilted up or down with a tilt cylinder 14.
  • the the upper tilting position of the console 15 is indicated by dash-dotted lines in FIG. 1 and marked with 15.1.
  • a swing-out sheet metal support 20 is provided with an extendable stop 21.
  • the bracket 15 carries a tong support 17, which is guided in a longitudinally sliding manner and is moved back and forth by a drive unit (not shown).
  • a height-adjustable turntable 24 is stationed between two brackets 15.
  • a sheet metal plate resting against the stops 21 for positioning is designated by 22.
  • FIGS. 3 and 4 show the pliers support 17 and the pliers 16 in an enlarged view.
  • the console 15 shown in section in FIG. 3 has two guides 15.2 and 15.3 in its longitudinal direction, in which the pliers support 17 is slidably guided. With a linear measuring system 23 embedded between the guides 15.2 and 15.3, the position of the pliers 16 is measured directly in relation to the bracket 15.
  • the pliers 16 with a fixed pliers part 16.1 and a closable pliers part 16.2 are arranged on the pliers support 17.
  • the pliers 16 can be rotated about a horizontal pliers axis 16.3 and can be pivoted forwards or backwards about a vertical pliers axis 16.4.
  • the corresponding movement of the pliers 16 is driven by a drive 16.5.
  • On the pliers support 17 is with an axis of rotation 18.1 the pliers table 18 is articulated, which is tilted up by the actuating cylinder 19 from a rest position 18.2 into a working position.
  • the upper pivot 19.2 of the actuating cylinder 19 is connected to the pliers table 18 and the lower pivot 19.1 to a carrier 17.1 of the pliers support 17.
  • the workpieces can be placed on the height-adjustable turntable in the present case.
  • a gripper device (not shown) to lift a single sheet of metal from a stack of sheets in front of the manipulation device, to bring it to a certain height in order to then be taken over by the tongs of the manipulation device according to the invention, which are pivoted backwards by 90 °.
  • the pliers run against the sheet metal edge facing them.
  • the associated pliers tables are swung out of their rest position by the force of the actuating cylinders and the sheet metal edge in the area of the pliers is raised to the correct level.
  • the tongs open, the tongs tables lower, and the consoles with the tongs supports move far enough away from the metal sheet to prepare for the next transport phase.
  • the pliers turn 90 ° back to their starting position and the pliers supports move along the side edges of the sheet metal up to the axis of the turntable.
  • the pliers tables are swung open again in order to raise the side sheet metal edges to the level for retracting the pliers.
  • sheet metal supports with stops are extended at the tool-side end of the brackets, which after the now following tilting movement of the brackets, the sheet metal plate support on the one hand and position precisely in the longitudinal direction on the other.
  • the pliers are moved on both sides over the side edges of the sheet metal plate until the sheet metal edge touches the base of the pliers mouth and the sheet metal plate is precisely positioned by the closing movement of the closable pliers parts.
  • the sheet metal supports on the tool side and the associated sheet stops are swiveled in again and the sheet is brought into the horizontal position at the die height.
  • the actual processing phase begins.
  • the sheet of metal is pushed over the die with the aid of the pliers and the pliers support which is guided in the guides and is moved by a drive, by a predetermined amount for the intended bend.
  • the tool stamp now executes its working stroke, during which the pliers can run free and, together with the pliers tables, follow the path that the sheet metal leg determines through the fold. While the tool stamp is being returned to its starting position, the pliers use the tilting cylinder to move the metal sheet with the first bend back to the horizontal position at the die height.
  • the device according to the invention it is possible, in addition to the simplest folding described above, to carry out the entire sheet metal handling for complicated folding operations, including positioning on the correct stop mass. For example, that of two opposite tongs lying on two sides, turned around a horizontal axis outside the tin table. If a rotation around a vertical axis is required, the sheet is moved by the horizontal movement of the pliers over the turntable and taken over by the raised turntable after opening the lockable part of the pliers. The tongs are retracted sufficiently and the sheet with the rotary table is rotated accordingly, for example by 90 °, 180 ° or 270 °. The sheet metal is then taken over by the pliers in the new position, repositioned and gripped and is ready for further processing.
  • the pliers can be rotated 90 ° forwards around the vertical axis of the pliers in order to grip the sheet on its fourth side, i.e. at the back, and thus the sheet to be fed to the tool stamp of the press brake with the third side.
  • the same operation could also be carried out with special, side-acting pliers that grip around the folded sheet ends and grip the sheet within the fold.
  • the vertical slide together with the bracket, the pliers and the gripped sheet metal plate, can be pushed with the help of the rack and pinion drive so that a sheet metal side that is folded down can be pushed over the die for another edging provided on the same side vertically upwards until the bottom edge of the sheet slightly exceeds the die height.
  • the pliers When moving the pliers, the sheet of metal is pushed over the die until the correct feed is achieved. Then the vertical slide lowers again until the sheet rests on the die and the edging can be carried out.
  • Similar devices as described above for feeding the metal sheets into the work area, could also be provided behind the press for guiding away and stacking the finished workpieces.
  • electromagnets could also be provided for special applications.
  • the pliers are also one the second, horizontal pliers axis (16.6), which runs perpendicular to the horizontal pliers axis (16.3), could be designed to be tiltable, so that, for example, side edges of a sheet already bent upwards or downwards could be gripped by the pliers from above or from below by a third or fourth Feed the edge of the sheet to the folding tool.
  • a device could also be provided in which the drive unit can be switched, especially in the case of thin sheets, that the pliers exert an adjustable force pulling away from the tool during the bending process so that the sheet remains stretched when edging.
