Definitions

  • the invention relates to a device for producing straight air duct parts with an angular cross-section Metal sheets according to the preamble of claim 1, and how in EP-A-496425.
  • Molded parts for air ducts differ in two Categories: Round tubes and rectangular tubes.
  • the rectangular tubes can be straight or curved.
  • the present invention relates to a device for producing straight tubes with angular cross section.
  • channel formers For the production of straight sewer pipes with rectangular Cross-section are so-called channel formers commercially available. It These are machines that have multiple devices combine.
  • a puller that pulls the sheet to be processed from the coil.
  • a straightening unit is provided, in which the originating from the coil Curvature of the sheet is eliminated.
  • one Beading device on the one or more parallel Stiffening beads, so-called Z-beads, in the sheet molded.
  • the corrugated sheet then runs into a bending bench, which bends the sheet metal strip several times at an angle, so that the desired tube is created. After all, the bending bench is one Tin snips assigned to those formed into the channel part Cut off sheet metal section. Closing the longitudinal seam takes place on a separate channel locking machine.
  • the present invention is based on the object To specify devices with the help of which duct parts the length of which deviates from the standard coil widths, have it manufactured extremely efficiently and also one have significantly reduced space requirements.
  • the special feature of the device according to the invention is the space-saving arrangement of the beads between the scissors and bending device.
  • the production an air duct part only requires three manual ones Activities, namely inserting the sheet of metal for cutting on width, turning sheet metal and inserting for cutting Length, insertion for beading. All other operations, especially adjusting the feed to the correct one Cutting and bending dimensions and the actuation of the hold-down devices, the scissors and the bending beam are program controlled and with high precision.
  • the device according to the invention can also as normal CNC stop shears or CNC stop bending bench to be used.
  • bending cheeks and Knife cheek formed in one piece and a set of Profile rollers integrated in it. This enables one particularly space-saving machine head with the possibility To produce air duct parts with a small bending dimension.
  • a continuous guide plate is provided so that a very good sheet guidance is achieved.
  • the feed is a stop trained, is behind the scissors and is motor controlled adjustable.
  • This construction variant enables high manufacturing accuracy.
  • the feed is realized for the metal sheets by transport rollers that are in front of the profile rollers in the machine head and driven by a motor.
  • This Construction variant leads to an even more compact and simpler structure of the device according to the invention.
  • the scissors advantageously move up and also bends the bending bench upwards. This allows the Actuators optimally cheap in the machine frame accommodate.
  • Profile rollers or the transport rollers are electromotive driven, preferably program-controlled. It understands yourself, but also a hydraulic or pneumatic Drive can be used.
  • Scissors and / or bending bench can be advantageously drive hydraulically or by electric motor.
  • FIG. 1 shows a side view and FIG. 2 shows a top view a device with the help of a rational production of air duct parts of any length and any Cross section from sheet metal is possible.
  • the actual processing station is formed by a Bending bench 10, a beading device 20 and a pair of scissors 30.
  • Fig. 3 shows a cross section in an enlarged view through bending bench 10, beading device 20 and scissors 30.
  • the bending bench 10 for processing a sheet 9 exists from one about its transverse axis 13 over 90 degrees pivotable bending beam 11, against one above the Sheet 9 positioned bending beam 12 works.
  • the scissors 30 consists of a below the sheet 9 positioned, upwardly movable scissor cheek 31, the against one positioned above the sheet 9 Scissor arm 32 with exchangeable scissor blades 33, 34 is working.
  • the beading device 20, with the help of Z beads in the Sheet 9 are incorporated, is located space-saving between bending bench 10 and scissors 30.
  • Sie consists of two sets of parallel profile rollers 21, 22, the lower roller set 22 against the upper roller set 21 can be delivered if the sheet 9 is corrugated shall be.
  • the bending beam 12 and the scissor beam 32 in one piece. You can do this with just one Drive - electric motor, pneumatics or hydraulics and take off. They can also do this at the same time as a bearing for the upper roller set 21 Beading device 20 serve.
  • the operator sets for the manufacture of air duct parts a sheet of metal from the front on the guide plate 4 and pushes them under bending bench 10, beading device 20 and Scissors 30 through to the stop 40.
  • the position of the Stop 40 was previously programmed to the Desired circumferential dimension of the molded air duct set.
  • the operator pushes the to insert the Z-beads Sheet in turn from the front into the machine.
  • the Profile rollers 21, 22 are fed to the correct size, the stop 40 moves back to the widest gauge.
  • the profile rollers 21, 22 grip the sheet metal piece 9 and pull it through the beading device. Is the sheet 9 completely beaded, it remains on the machine table 3 lie.
  • the stop 40 now moves along to produce the channel part the corrugated sheet 9 before a sheet section the desired width is located under the bending bench 10.
  • the Bending beam 11 pivots upwards under program control; thereby the first bending edge is created.
  • the channel part is ready and can be done be pulled out of the machine at the front.
  • Fig. 4 shows a side view of an alternative device for the rational production of air duct parts Length and any cross-section from sheet metal.
  • the basic structure of this device corresponds to that of 1. However, the device according to FIG. 1 is missing programmable stops 40. Instead, the Feeding the metal sheets by two in front of the profile rollers 21, 22 positioned transport rollers 27, 28 causes.
  • Fig. 5 shows a cross section in an enlarged view through bending bench 10, beading device 20 'and scissors 30. Bending arms 12 and scissor cheek 32 are again in one piece trained, can therefore be Electric motor, pneumatics or hydraulics - deliver and take off.
  • the profile rollers 21, 22 are a upper and lower set of transport rollers 27, 28, the the metal sheets 9 program-controlled by the device transport. Thanks to these transport rollers 27, 28 could the workflow can be accelerated again.
