Definitions

  • the present invention relates to a folding closing machine for closing fold connections in the production of sheets consisting of sheet segments from sheet metal, according to the preamble of claim 1.
  • Folding closing machines of this type are already known. So e.g. US-A-4 006 520, in particular in FIGS. 1 and 2 and in columns 3 and 4, describes and illustrates a seaming machine of the type mentioned above.
  • a closing wheel is rotatably mounted in a closing wheel carriage, the closing wheel including the support roller forming an acute angle.
  • the shafts of the locking wheel and the support roller are only supported on one side.
  • This embodiment also has resilient components and the part carrying the locking wheel can be pushed mechanically.
  • this solution has the disadvantage that it is only suitable for fold connections of sheets which are sufficiently large because two wheels have to press on the fold surfaces and are rotatably supported in relatively large supports.
  • the invention has for its object to provide a seaming machine of the type mentioned, with which one can also process small sheets or thick sheets.
  • the seaming machine should also be able to work with a very high pressure.
  • the above-mentioned object is achieved in that the closing wheel slide is held in support with a guide plate which is loaded by means of compression springs, and in that the closing wheel slide is mechanically connected to a hydraulic cylinder for its infeed.
  • the advantage of the invention is that the closing wheel can also operate in a limited space and that it can exert sufficient pressure on the sheet metal to be machined by means of advantageous carriage guidance, so that sheets can also be produced from relatively thick sheet metal.
  • This form of training enables a simple and sufficiently massive assembly of the closing wheel slide.
  • the closing wheel mounted in the closing wheel slide can thus be delivered with sufficient force, whereby the fold is closed.
  • the cylinder can be advanced in one or more steps by appropriate control. This allows the folding of thick sheet metal.
  • closing wheel slide is spring-mounted in a support. This solution makes it easier to close seam connections even if the sheet thickens, e.g. arises when processing the seam. In this case the closing wheel slide can move upwards.
  • the acute angle between the closing wheel slide and the support surface of the support roller is 20 ° to 30 °. This angle allows both the penetration of the closing wheel when producing small sheets and the achievement of the necessary pressure on the area to be processed.
  • the hydraulic cylinder is provided with an adjusting nut for adjusting the maximum stroke. This allows you to adapt the working method to the predetermined dimensions of the fold.
  • the support carrying the closing wheel slide is fastened on a feed slide and the support roller is rotatably mounted in this feed slide. This construction facilitates both the delivery and the extension of the sheet.
  • a tool part A according to FIG. 1 contains an only partially drawn feed roller 1, a support roller 2 with a fixed axis of rotation and a closing wheel 6 which is rotatably mounted in an elongated recess of a closing wheel slide 5.
  • the closing wheel slide 5 is slidably mounted in a recess of a support 4.
  • the closing wheel slide is held from above by means of a guide plate 9.
  • This guide plate 9 is fastened to the support 4 with screws 8, the heads of these screws 8 being provided with compression springs 7, so that the guide plate 9 presses the closing wheel slide 5 into the recess of the support 4 with a sufficient force.
  • 7 disc springs were used as compression springs.
  • the support 4 is fastened on a feed slide 3, the support roller 2 also being rotatably mounted in this feed slide 3.
  • the closing wheel slide 5 is mechanically connected to a hydraulic cylinder 10.
  • the maximum stroke of the cylinder 10 is designated B and is adjustable by an adjusting nut 11.
  • B The maximum stroke of the cylinder 10
  • C The length of the machined parts of the arch segments 12 is designated by C.
  • This figure 1 shows a position of the closing wheel 6 in which a fold has already been made. As is clearly visible from FIG. 1, the fold 12 'is supported on the support surface 2' of the support roller 2, held from the left with the feed roller 1 and pressed from above with the closing wheel 6.
  • FIG. 2 shows parts of two arch segments 12 and a fold 12 ', which is shown in three different phases of closing because of the clarity.
  • the vertical position is the starting position for processing, the diagonally drawn position shows an intermediate layer and the horizontally drawn position shows the finished seam connection.
  • FIG. 3 shows the overall arrangement of the seaming machine with the previously described tool part A according to Figure 1.
  • the same parts are given the same designations in all figures.
  • the support roller 2 is shown in FIG. 3 and the feed carriage 3, the feed roller 1 and the arc segments 12, which are only symbolically represented.
  • the basic machine D which carries the tool part A, is known per se from various solutions and is therefore only shown in simplified form and described.
  • a hydraulic unit 14 is arranged in a machine stand 13 and feeds two hydraulic motors 15 for driving the moving parts.
  • a cylinder 16 is intended for the movement of the feed carriage 3 already shown in FIG.
  • a bracket 17 is used to support arch consisting of the arch segments 12.
  • the subject of the invention has proven itself extremely well for the closing of folded joints in the production of pipe bends from sheet metal.
