Definitions

  • the invention relates to a device in connection with a system for punching sheet metal parts from strip-shaped raw sheet, which is delivered in coils, with a cassette-like container for receiving a coil, which is formed by a frame with support rollers for a coil is.
  • stamping technology it is common to supply the required semi-finished product, i.e. the raw sheet, in rolls, which are referred to as coils. Usually these coils are refurbished to the end. For this purpose, the actual punching machine is assigned an adjustable reel for feeding the strip material from the coil.
  • JP-A-58 145 315 a system for punching sheet metal parts from raw sheet metal is known with a punching machine and a feed device for strip material, the punching machine being assigned a laterally displaceable slide for cassette-like containers. It is essentially a matter of reducing the set-up times and increasing the work efficiency by means of program control, a new cassette being able to be automatically moved into the desired position when the tape is changed. For this purpose, the cassettes must be designed identically as a feed device for coiled strip material.
  • cassettes for coils arranged on a carriage are known, in which the lateral spacing of the cassette walls can be adjusted via a chain gear.
  • the cassettes themselves are constructed identically again, with such a device, in particular, to reduce the set-up time when changing the cassette.
  • a corresponding receiving device for several coils is described in US-A-34 72 463.
  • the coils are stored next to each other in an open, laterally displaceable container on continuous rollers and the end of the strip is pulled between two rotating rollers.
  • US-A-38 10 588 there is a closed container for a single coil of elastic material with bearing rollers and pulling means in the container wall.
  • this device appears unsuitable for metal strips.
  • DE-C-0 620 298 specifically discloses a machine for unrolling winding bundles, in particular rolled-up strip-shaped rolling stock, in which the inner radius of the coil in particular can be adjusted using a pressure roller.
  • this machine must be loaded with a coil, which means that considerable conversion work is necessary.
  • the known devices can only be used sensibly if there are large batch sizes in production and the coil change is to be carried out quickly.
  • the press tool is usually loaded with individual strips by hand. Automatic strip processing would only be possible with existing skeletons. At the beginning of the strip, punching must be carried out and, in order to avoid half parts, the strip can only be processed except for a remainder specified by the punching tool. After the punching operation has ended, the remaining strip must be pulled out of the tool.
  • the object of the invention is therefore to provide a device which is used both as a storage device and as a drain device for coils can be used and which is to be used in connection with a system for punching sheet metal parts from coils.
  • the frame has a centering device for the outside and / or inside diameter of the coil and a lateral guide for the coil which can be adjusted to different widths, with adjustable rollers in the frame as a centering device for adaptation to the outer and / or inner diameter of the coil are arranged and the guide is formed by a side cover of the frame, which can be swung out for the insertion of a coil, and that in the frame a vertically displaceable device for carrying out the strip-shaped raw sheet pulled off the coil is arranged, which is also a clamping device for forms the end of the tape.
  • the device according to the invention can be integrated into an existing system with a laterally displaceable slide of the feed device for the strip.
  • several devices according to the invention can now be provided with sheet metal strips of different widths and / or thicknesses and of different materials stored in coils, the device assigned to the punching machine being activated in each case and from there the strip end being introduced into a pulling device of the punching machine . After the order has been processed, the end of the coil is clamped in the device for carrying out the strip and is available there for a new processing operation.
  • the frame advantageously has cross members as a base and / or as a support for the cover.
  • Such a frame can easily be used in the slide of the overall system which can be moved laterally to the punching machine.
  • the device serves as both a storage for the coils and a drain device.
  • the hinges for the pivoting lid and the locking mechanism for the lid are slidably mounted so that, for example, roughly 25 to 180 mm wide sheet metal strips can be used. So that the lid can be adapted to the respective width of the coil, which always ensures sufficient lateral guidance.
  • two adjustable rollers are preferably provided, which are guided from above to the outside diameter or from the inside to the inside diameter of the coil and can be adapted to the changing diameter during punching operation. Since the device arranged on the frontal side of the cassette for carrying out the tape can be moved vertically with the associated clamping device, it can be adapted to the different inlet heights.
  • the invention therefore enables immediate access to strip material of different widths and / or thicknesses and material at any time. A quick changeover can now take place.
  • the invention therefore results in significant simplifications in the routine operation of stamping shops, as a result of which the automation is further improved.
  • 100 denotes a storage device for band-shaped coils which are assigned to a punching machine 200.
  • the pulling and straightening device for the sheet metal strip in the punching machine 200 is designated 205.
  • the bearing device 100 consists in detail of a slide 10 which is laterally displaceable to the insertion device 205.
  • a plurality of cassette-like containers, which are denoted by 1, II and 111 in FIG. 1, are arranged on the carriage 10.
  • the cassette-like containers I to 111 are each identical and can carry different types of coils with semi-finished products. The containers are described in detail using the following figures.
  • cassette-like containers 1 to 111 are arranged in different adjustment on the bearing device 100 with slide 10. They each consist essentially of a vertical frame 1 with a plurality of stiffening ribs. The bottom one forms a base 2 and is arranged in a sliding carriage 10 on the bearing device 100 such that one of the cassettes I to 111 can be brought into the punching machine in the operating position.
  • two cross members 11 are fixed, which carry a cover 3 which can be moved in the transverse direction.
  • Another traverse 12 is welded to the upper side and has a support ring 9. With a crane or the like, the complete container with coil can be lifted during replacement.
  • the cover 3 is mounted in the frame 1 in hinges 4, which in turn can be displaced in the recesses 111 in the cross members 11. A specific position can be fixed by means of the locking lever 41.
  • the cover 3 can be pivoted away on the one hand for inserting a coil into the cassette; in that the hinges and the locking mechanism for the cover 3 are mounted so that they can be moved continuously,
  • coils of different widths can be used, for example in the range from 25 to 180 mm.
  • the lid 3 can thus be adapted to the respective width of the coil, so that the frame 1 on one side and the lid 3 on the other side lateral guidance for the belt is guaranteed.
  • a coil 20 or 20 ' is indicated in FIG. 3. Its outer diameter rests on four transverse support rollers 6, which can also be seen in FIG. 2. On the circumference of the coil there are further rollers 7, which can be adjusted centrally inwards in recesses 8 of the cover 3 or the frame 1.
  • the rollers 7 are brought up from above onto the outside diameter of the coil 20 and can adapt to its changing outside diameter. This also ensures that the coil 20 cannot be pulled out of the said container in the event of a jerky withdrawal.
  • the rollers 7 can also be guided centrally in the grooves 8 to the inside diameter of the coil 20 and act as a centering device. Combinations of inner and outer rollers, each of which is fixed in a suitable position, are also possible, which is indicated in FIG. 3.
  • a vertically displaceable pulling and clamping device 15 for the beginning of the band.
  • This consists in detail of a height-displaceable roller 16, to which a clamping piece 18, which can be actuated by means of a hand-operated knurled wheel 17, is assigned.
  • the production of stamped parts can be carried out according to a new working method: the slide with various cassettes is stationed near the stamping machine. This enables immediate access and quick changeover to a new range or material. Since the beginning of the tape is fixed in the clamping device, feeding to the punching tool can take place quickly after a corresponding lateral displacement.
  • a punching machine can therefore not only be used more economically in the method described; Incorrect punching and tool damage will also be reduced effectively.
