Definitions

  • the invention relates to a bending machine with a backgauge positioning system with a backgauge, as well as a method for positioning the backgauge.
  • a back stop for a sheet metal bending machine is known in which a stop finger can be displaced relative to a base unit.
  • the stop finger can be locked by means of a locking pin, which can be moved into a corresponding hole in a guide rail.
  • the one from the DE 3739949 C1 The known backgauge has the disadvantage that when the safety function of the stop finger is activated, the automatic operation of the stop finger is available to a limited extent.
  • a backgauge is known in which a stop finger can be displaced relative to a base unit when a predetermined force is exceeded and a magnetic fixation is thereby released.
  • the one from the EP 2 915 604 A1 known backgauge has the disadvantage that the predetermined force for releasing the magnetic fixation must be selected to be correspondingly low in order to ensure that the safety function is maintained.
  • the necessarily weak dimensioning of the magnetic fixation can, however, lead to it being released unintentionally when sheet metal workpieces strike.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a device and a method by means of which a backgauge can be positioned with increased security, while the full functionality of the backgauge is to be retained.
  • a bending machine with a back stop positioning system is designed with a back stop.
  • the back stop comprises a stop finger on which at least one stop surface is formed, a base unit which is designed to be coupled to the back stop positioning system, the stop finger being coupled to the base unit by means of a linear guide and the stop finger relative to the base unit between a pushed forward working position and a retracted position is movable.
  • the stop finger and the base unit are coupled to a restoring device, in particular a first spring element, by means of which the stop finger is biased into its working position.
  • a switchable locking device is formed, by means of which the stop finger can optionally be locked in the working position or is released for displacement, in particular against the spring force of the first spring element, into its retracted position.
  • the advantage of the design of the bending machine according to the invention is that the stop finger is pretensioned in its working position by means of the first spring element. It can thereby be achieved that the stop finger is moved back into its working position after a displacement, as soon as an acting force causing the displacement is removed again. Furthermore, the stop finger can optionally be locked in its working position by means of the locking device or released for displacement against the spring force of the first spring element.
  • the locking device can be used to implement a stop mode in which the stop finger is locked in its working position and is thus designed to stop sheet metal workpieces to be bent.
  • the back stop When the locking device is deactivated, the back stop is in a so-called safety mode or travel mode, in which the stop finger can be moved relative to the base unit, only the spring force of the first spring element having to be overcome.
  • the spring force of the first spring element is selected to be correspondingly low, since when the rear stop moves, in addition to the spring force of the first spring element, the inertia of the stop finger acts on the obstacle.
  • the locking device comprises a holding part, in particular an electromagnet, wherein the stop finger can be locked relative to the base unit by applying activation energy in the holding part.
  • a holding part in particular an electromagnet
  • the stop finger can be locked relative to the base unit by applying activation energy in the holding part.
  • the advantage here is that an electromagnet in an automated bending machine can be easily activated or deactivated.
  • electricity is available as an energy source for the electromagnet on every bending machine.
  • an electromagnet also has the advantage that there are no mechanically displaceable components that are subject to wear or that have to be serviced. An electromagnet can thus have an increased service life.
  • the locking device has a mechanically acting locking unit.
  • the stop finger can be fixed in its position relative to the base unit by means of the mechanically acting locking unit.
  • the mechanically acting locking unit of the locking device is designed to produce a form-fitting connection between the stop finger and the base unit.
  • a positive connection can be achieved, for example, by means of a shaped element which is arranged on the base unit and which is pushed into a corresponding recess in the stop finger.
  • the shaped element has a wedge surface. It can thereby be achieved that the positioning accuracy of the backgauge unit can be increased, since the stop finger can be pressed into its working position by the wedge surface.
  • the shaped element can be designed, for example, in the form of a dowel pin.
  • a dowel pin can, for example, also have a conical shape in order to be able to achieve an exact positioning of the stop finger.
  • the shaped element can be pushed into the recess of the stop finger by means of variously designed actuators.
  • the actuators can be designed, for example, in the form of pneumatic or hydraulic cylinders, electric linear or rotary drives or electromagnets.
  • the mechanically acting locking unit comprises a clamping device and not a form-fitting but a frictional connection is established.
  • the positive connection can be established by means of a micro-toothing.
  • a second spring element is formed, which is coupled to the stop finger and the base unit with the interposition of the locking device, the stop finger being fixed in its working position by means of the second spring element when the locking device is locked.
  • the second spring element has a greater spring stiffness than the first spring element and / or that the second spring element has a greater prestress than the first spring element.
  • the first spring element can, for example, have a spring stiffness between 0.01 N / mm and 1N / mm, in particular between 0.1 N / mm and 0.5 N / mm, preferably approximately 0.2 N / mm.
  • the first spring element can have a pretension between 1N and 15N, in particular between 3N and 10N, preferably approximately 7N.
  • the second spring element can, for example, have a spring stiffness between 0.1 N / mm and 30N / mm, in particular between 1 N / mm and 10 N / mm, preferably approximately 2 N / mm.
  • the first spring element can have a pretension between 20 N and 600 N, in particular between 160 N and 450 N, preferably around 250 N to 300 N.
  • an embodiment is also advantageous, according to which it can be provided that the holding part of the locking device is received on the base unit in a non-displaceable manner relative to the base unit in the main adjustment direction and that the locking device has a counter-element which interacts with the holding part and is arranged on a guide rod, the guide rod at least is mounted on a first bearing jaw, wherein the counter element is arranged at an end region of the guide rod and the second spring element is arranged with respect to the first bearing jaw opposite to the counter element on the guide rod.
  • the electromagnet is held immovably on the base unit relative to the base unit and that the locking device has a counter-element which interacts with the electromagnet and is arranged on a guide rod, the guide rod being mounted on a first bearing jaw and on a second bearing jaw , which are arranged at a distance from one another, the counter-element being arranged in accordance with a cantilever bearing closer to the first bearing jaw on an end region of the guide rod lying outside the two bearing jaws.

  • the guide rod is additionally mounted on a second bearing jaw, the first bearing jaw and the second bearing jaw being arranged at a distance from one another.
  • a stop element for the second spring element is formed on the guide rod, wherein the second spring element is designed as a compression spring and is received between the first bearing jaw and the stop element on the guide rod, whereby the stop element by means of the second spring element from first bearing jaw away and thereby the counter-element is biased towards the first bearing jaw.

  • the stop finger can be biased into its working position.
  • the holding part is designed as an electromagnet and the counter-element is designed as a disc interacting with the electromagnet, which is arranged on the front side of the guide rod, the electromagnet and the counter-element resting against one another on contact surfaces.
  • the advantage here is that such a connection can be switched with a very short switching time.
  • the electromagnet and / or the counter-element are accommodated on a joint mounting so that the contact surfaces can be aligned parallel to one another.
  • This measure can reduce the air gap between the two contact surfaces and thereby increase the holding force of the magnet.

This can save weight.
  • a force sensor is designed which is designed to detect the amount of an effective force. This measure enables the impact force of a sheet metal workpiece to be impacted to be recorded. This makes it possible to signal to the machine operator when the sheet metal workpiece is resting against the stop finger with a predefined stop force and thus correct positioning of the sheet metal workpiece has been achieved.

  • the advantage here is that the status of the locking device can be displayed to the machine operator by the display element and the machine operator is informed whether the bending machine is ready to strike the sheet metal workpiece to be bent.
  • a sensor element is formed which is used to detect a relative movement and / or relative position between the stop finger and the base unit.

  • the advantage of the method according to the invention is that a so-called travel mode or safety mode can be set when the backgauge is positioned, in which the stop finger can be displaced relative to the base unit.
  • This allows the stop finger to move when it touches an obstacle, such as the hand of a machine operator move relative to the base unit so as not to injure the machine operator.
  • the displacement path is selected to be so large that if the stop finger touches the obstacle, the displacement movement of the backgauge can be stopped within this displacement path.

  • the joint mounting 64 is designed in the form of a universal joint.
  • a universal joint or joint bearing 64 designed in this way can of course not only be used to hold the counter element 43, but it is also possible for the joint bearing 64 to be designed to hold the electromagnet 42b and to be arranged between the electromagnet 42b and the base unit 21. Such a design of the rear stop 15 is not shown separately.
  • FIG. 9 shows a schematic representation of a further exemplary embodiment of the backgauge 15, again with the same reference numerals or component designations as in the preceding for the same parts Figures 1 to 8 be used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 1 to 8.
  • the counter element 43 is rigidly coupled to the guide rod 46 and that the complete guide rod 46 together with the counter element 43 is accommodated in the first bearing jaw 47 in a slightly pivotable manner.
  • the bearing point between the first bearing jaw 47 and the guide rod 46 is designed in the form of a play bearing so that a slight angular pivoting or a slight radial displacement between the guide rod 46 and the first bearing jaw 47 can be compensated for.
  • the joint bearing 64 is designed in the form of a spherical head.
  • the contact surface 63 of the counter element 43 can be adapted to the contact surface 62 of the electromagnet 42b.
  • the force sensor 60 In order to detect the effective force 50 applied to the stop surface 17, provision can also be made for the force sensor 60 to be designed in the form of a tensile force measuring unit between the electromagnet 42b and the base unit 21.
  • Fig. 10 shows a further embodiment of the backgauge unit 15, again for the same parts the same reference numerals or component designations as in the preceding Figures 1 to 9 be used.
  • the backgauge unit 15 again for the same parts the same reference numerals or component designations as in the preceding Figures 1 to 9 be used.
  • the locking device 41 is designed to lock the guide rod 46 by means of a form-fitting connection.
  • a notch 65 is arranged in the guide rod 46, by means of which a shaped element 66 interacts, the shaped element 66 being designed to be pushed into the notch 65. The shaped element 66 is pushed into the notch 65 in the securing direction 67, as a result of which the guide rod 46 is locked.
  • the stop finger 18 is positioned in its working position 28 in that an end stop is formed on the base unit 21 and the stop finger 18 is pressed against this end stop by means of the first spring element 34.
  • the shaped element 66 has a wedge surface 68. This can ensure that the guide rod 46 can be locked in the working position 28 of the stop finger 18.
  • an adjusting device 69 is formed, by means of which the shaped element 66 can be displaced in the securing direction 67.
  • the securing direction 67 is designed transversely to the main adjustment direction 20.
  • the adjusting device 69 can also comprise an electromagnet 42b, by means of which the shaped element 66 can be pushed into the notch 65.
  • the shaped element 66 is received on a guide rod which is displaceably mounted in the electromagnet 42b.
  • a spring element can be formed by means of which the shaped element 66 can be brought out of engagement with the notch 65 again when the electromagnet 42b is released.
  • the force sensor 60 is coupled to the holding part 42a and the effective force 54 can thereby be determined.
  • FIG. 11 Another embodiment of the backgauge 15 is shown, again with the same reference numerals or component designations for the same parts as in the previous ones Figures 1 to 10 be used. In order to avoid unnecessary repetition, please refer to the detailed description in the preceding section Figures 1 to 10 pointed out or referred to.
  • the holding part 42a of the locking device 41 is designed in the form of a pneumatic cylinder which has a pressure head 70 which interacts with a pressure projection 71 of the stop finger 18.
  • the stop finger 18 can be pressed against an end stop by the pressure head 70 and thereby be preloaded in its working position 28.
  • the force sensor 60 is designed as an end stop, against which the stop finger 18 is pressed. In this way, the acting force 54 can be detected.
  • a buffer element 72 can be formed, which can be arranged next to the force sensor 60 and protects the force sensor 60 from excessive shock loads.
  • the buffer element 72 can be designed, for example, in the form of a hydraulic shock absorber.
  • the pneumatic cylinder When the pneumatic cylinder is extended and the drive head 70 is pressed against the stop finger 18, the pneumatic cylinder itself can act as a second spring element 51, since the air acting in the pneumatic cylinder is compressible. By presetting the pressure in the pneumatic cylinder, the spring force of the second spring 51 can thus be adjusted.
  • the pneumatic cylinder is retracted into its retracted position and the stop finger 18 is thus released for movement in the main adjustment direction 20, with only the low spring force of the first spring element 34 biasing the stop finger 18 into its working position 28.
