Definitions

  • the invention relates to a method for punching sheet metal parts, in which a blank sheet is supplied in strip form to a punching machine and processed into punched parts, the sheet metal strips supplied in coils being arranged in cassette-like containers which are assigned to the punching machine by lateral displacement.
  • the invention also relates to a system for carrying out the method, consisting of a punching machine with tools and a feed device for tape material from cassette-like containers, the punching machine being assigned a laterally displaceable carriage for the cassette-like containers, and to a device for use in this facility.
  • a device consists of a cassette-like container for receiving a roll of strip-shaped raw sheet (coil).
  • 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 sheets is known with a punching machine made of tools and a feed device for tape material from cassette-like containers, the punching machine being assigned a laterally displaceable carriage for the cassette-like containers. It is essentially a matter of reducing the set-up times and increasing the work effectiveness by means of program control, and a new cassette can be automatically moved into the desired position when the tape is changed.
  • 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.
  • the known devices are to be used sensibly when there are large batch sizes in production and the coil change is to be carried out quickly.
  • the stamped parts were previously made from strips for orders with small lot sizes.
  • the strips are cut using a pair of guillotine shears from a sheet of raw sheet metal.
  • the metal sheets and the strips that have already been cut are therefore conveniently stored in the punching area.
  • more strips are generally to be provided than actually calculated from the lot size. Leftover strips go back to the strip storage or are added to the punch waste.
  • the size of the sheet metal bearing must therefore be adapted in accordance with the number of different materials to be processed and the strip dimensions.
  • 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 you have to punch and you can, to avoid half parts, the strip can only be processed to the extent specified by the punch. 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 method and a system for punching out small sheet metal parts, in which it is not necessary to work with sheet metal strips.
  • a device with a cassette-like container suitable for use in this method is also to be created.
  • the object is achieved according to the invention in that, for processing small batch sizes, several containers with coils of sheet metal strips of different widths and / or thicknesses and of different materials are available, of which the front end of the strip passes through an opening of the container assigned to the punching machine and in one Pulling device of the punching machine is introduced, and that after the processing the strip end of the coil is clamped in the opening of the container and is available there for a new processing operation.
  • the slide and / or the containers for receiving coils are made of sheet metal strips of different widths and / or thicknesses and of different sizes Materials trained.
  • the container is formed by a frame with support rollers for each coil, which has a centering device for the outer and / or inner diameter and a lateral guide for the coil.
  • the frame advantageously has cross members as a base and / or as a support for the centering device.
  • Such a frame can easily be used in the slide of the overall system which can be moved laterally to the punching machine.
  • a plurality of such devices, which contain different coils, can then be arranged next to one another, so that a quick changeover during punching operation from a first to a different bandwidth or from a first to a different material can be achieved by simply moving the slide laterally.
  • the above device thus serves both as a bearing for the coils and as a drain device.
  • the lateral guidance takes place on one side through the frame and on the other side through a cover.
  • the lid is attached to two hinges and can be swung away to insert the coils into the cassette.
  • the hinges and the locking mechanism for the lid are mounted so that they can be moved continuously so that, for example, tapes of different widths can be used from about 25 to 180 mm. So that the lid can be adapted to the respective width of the coil, so that sufficient lateral guidance is guaranteed.
  • two adjustable rollers are preferably provided, which are connected to the outside diameter from above or from the inside to the inside diameter of the coil and can be adapted to the changing diameter during punching operation.
  • a device for guiding the tape with an associated clamping device is arranged, which can be moved vertically and can thus be adjusted 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. This enables a quick changeover.
  • 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 can be displaced laterally to the insertion device 205.
  • a plurality of cassette-like containers, which are denoted by I, II and III in FIG. 1, are arranged on the carriage 10.
  • the cassette-like containers I to III 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 I to III are arranged in different adjustments on the bearing device 100 with a slide 10. They each consist essentially of a vertical frame 1 with a plurality of stiffening ribs. The bottom one forms a footprint 2 and is arranged in a sliding carriage 10 on the bearing device 100 such that one of the cassettes I to III 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; characterized in that the hinges and the locking mechanism for the cover 3 are mounted so as to be continuously displaceable, coils of different widths can be used, for example in the range from 25 to 180 mm, the cover 3 can thus be adapted to the respective width of the coil so that through the frame 1 on one side and the cover 3 on the other side, the lateral guidance for the band is guaranteed.
  • a coil 20 or 20 ' is indicated in FIG. Its outer diameter rests on four transverse support rollers 6, which can also be seen in FIG.
  • 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 centered in the grooves 8 on the inner diameter of the coil 20 are brought up 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.
  • cassette-like containers I to III described are set to different widths.
  • coils with the dimensions 25 to 180 mm and also of different thicknesses, for example between 0.5 to 3 mm, can be stored, the semi-finished product also being able to consist of different materials.
  • 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 according to the invention; Incorrect punching and tool damage will also be reduced effectively.
