Definitions

  • the invention relates to a machine for bending a sheet metal edge provided on a first sheet metal part to form a second sheet metal part to be connected to the first sheet metal part and having at least one preferably driven pair of form rollers, the form rollers of which roll on the opposite sides of the sheet edge along the longitudinal edge thereof and its roll gap in the feed direction is inclined in the bending direction towards the second sheet metal part, one of the form rollers engaging under the sheet metal edge on its side facing the second sheet metal part, and with a support which is effective transversely to the feed direction and has at least one abutment supported on one of the sheet metal parts.
  • Such a machine is known as a folding closing machine for producing so-called Pittsburgh folds.
  • the latter are corner folds, as are provided, for example, on air ducts of air conditioning and / or ventilation systems which are rectangular in cross section and made of sheet metal.
  • air ducts are delivered to the installation site in individual parts.
  • At least part of the channel wall is folded approximately S-shaped to form a pocket extending in the longitudinal direction of the channel.
  • a wall element abutting the folded wall part is bent at right angles and is inserted into the pocket described, formed by an S-bend of the assigned wall part, for mounting the air duct.
  • the edge of the folded wall part which merges into the S-arch forming the pocket projects beyond the wall element which is bent at its longitudinal edge.
  • This protruding sheet metal edge is finally folded over and pressed against the wall part abutting the sheet metal edge at a substantially right angle to produce the fold connection by means of the customary folding closing machine.
  • the seaming machine is attached to the sheet metal edge of the folded wall part, which is initially approximately perpendicular to the adjoining wall element, and is guided along the sheet metal edge in the feed direction, ie in the longitudinal direction.
  • the form rollers of the pair of form rollers that roll on the sheet metal edge cause the sheet gap to bend towards the bent wall element due to the inclined position of their roller gap.
  • the form rollers endeavor to leave the desired plane of movement in the feed direction and essentially perpendicular to the sheet edge in the starting position towards the free longitudinal edge of the sheet edge.
  • the above-mentioned support with at least one abutment is used on generic machines.
  • a cylindrical support roller which is attached to a cantilever projecting from the machine base body, is used as an abutment on the known folding closing machine.
  • the previously known machine is braced across the corner region of the air duct to be assembled.
  • the machine is guided on one side of the channel corner over the form rollers on the sheet metal edge to be bent and is supported on the other side of the channel corner over the support roller on the assigned wall part of the air channel. So that the support roller can prevent the folding machine from breaking out of the desired plane of movement according to its intended use, its axis of rotation is aligned at an acute angle with respect to the assigned channel wall.
  • the support roller When the seaming machine moves in the feed direction, the support roller accordingly rolls on the channel wall with the jacket edge running in the circumferential direction of its base area and designed as a tapered edge. It engages in a running in the longitudinal direction of the channel wall a groove-like gap that has resulted from the folding of the wall part in question. Since the gap available for the intervention is very narrow, the tapered edge of the support roller may only be narrow. In addition, the support roller must be adjustable to compensate for tolerances that occur when bending the bag. The tensioning force by means of which the seaming machine is held in the corner area of the ventilation duct is introduced into the duct wall via the tapered edge of the support roller. As a result of the contact between the pointed edge of the support roller and the channel wall and simultaneous application of force to the support roller, undesired deformations and damage to the channel wall along the path of movement of the support roller occur when using the known folding closing machine.
  • the object of the present invention is to remedy this disadvantage.
  • the abutment (s) is (are) lagging the pair of forming rollers in the feed direction on a machine of the type mentioned and is supported (supported) on the side of the sheet metal edge facing the second sheet metal part.
  • the support to ensure the desired movement path of the machine is susceptible to deformations and damage and by deformations or damage relocated areas of the sheet metal parts to be joined that are impaired in their function or in their appearance.
  • At least one sliding shoe supported on the sheet metal edge is provided as the abutment of the support.
  • damage and / or deformations in the area of the sheet edge preventive way of introducing supporting forces to be transmitted is achieved in that the slide shoe (s) is supported (supported) by a sliding surface on the sheet edge.
  • At least one abutment roller rolling on the sheet metal edge in the feed direction is provided on a further embodiment of the machine according to the invention as an abutment of the support.
  • the movement resistance opposed to the feed of the machine due to its support is reduced when using support rollers compared to embodiments with sliding shoes.
  • a preferred variant of the invention is characterized in that a roller of a second pair of form rollers is provided as an abutment roller, which is arranged to lag the first pair of form rollers in the feed direction and whose form rollers roll in this direction on opposite sides of the sheet metal edge, the roller gap of the second pair of form rollers in the bending direction is preferably more inclined towards the second sheet metal part than the roller gap of the first pair of form rollers.
  • the second pair of form rollers can be used as a component of the machine support and thus perform a double function.
  • roller gap is more inclined than the roller gap of the leading pair of rollers, it serves to bring the edge of the sheet bent by the leading first pair of shaping rollers closer to the second sheet metal part in a first machining step in the direction of the second sheet metal part; at the same time, the form roller of the second pair of form rollers, which engages under the sheet metal edge, takes on the task of counteracting the machine from breaking out.
  • a multiple and therefore particularly effective support of the machine results in a further development of the invention when using two pairs of form rollers arranged one behind the other in the feed direction in that the abutment of the support has at least one slide shoe arranged in the feed direction between the form roller pairs and / or at least one slide shoe lagging the second pair of form rollers includes.
  • cylindrical form rollers can be used on machines according to the invention, the axes of rotation of which then run parallel to the roller gap.
  • an embodiment is preferred in which the form rollers of the first and / or the form rollers of the second pair of form rollers are conical. In this case, the axes of rotation of the form rollers run perpendicular to the feed direction.
  • Generic machines which have a guide plate resting on the second sheet metal part and displaceable in the feed direction with the machine.
  • Such a machine is modified in the sense of the invention in that at least one projection projecting from the guide plate to the sheet metal edge is provided as the abutment of the support.
  • Support lug is a support cylinder protruding in the axial direction from the form roller (s).
  • At least one abutment of the support can be adjusted perpendicular to the sheet edge in a further development of the invention.
  • the shaping rolls of at least one pair of shaping rolls in particular also the shaping rolls of the pair of shaping rolls serving as abutment for the support, are relative in order to adjust the width of the roll gap in the transverse direction of the sheet metal edge are adjustable to each other.
  • the mentioned feature also opens up the possibility of placing the machine at any point on the sheet metal edge or removing it from the sheet metal edge at any point.
  • the form rollers are preferably adjustable relative to one another by means of an adjusting device.
  • roller gap to changing sheet thicknesses, for example also in the case of dimensional tolerances on one and the same sheet metal part, is made possible according to the invention on a machine on which at least one form roller of at least one pair of form rollers is resiliently supported in the transverse direction of the sheet edge.
  • a pressing device which serves to press the sheet metal edge of the first sheet metal part bent by means of the shaping rollers at the end of the machining process on the second sheet metal part.
  • a sliding block moved with the machine in the feed direction is used for this purpose.
  • Such machines are further developed in accordance with the invention in that a cylindrical roller which follows the shaping rollers and the abutment (s) of the support in the feed direction is provided as a pressing device, the axis of which runs parallel to the plane of the second sheet metal part.
  • the tendency of the machine to leave the desired trajectory when using a cylindrical roller as a pressing device is less than when using a sliding block.
  • the support of machines according to the invention on the sheet metal edge is thereby simplified.
  • a folding closing machine 1 the machine base 24 of which is indicated by dash-dotted lines, is used to produce a ventilation duct with a rectangular cross section.
  • a fold connection is to be made between a first sheet metal part 2 and a second sheet metal part 3.
  • connection is made using a Pittsburgh fold, as shown in FIGS. 2 and 3 can be seen in its basic training.
  • the first sheet metal part 2 is folded in an S shape to form a pocket running in the longitudinal direction of the ventilation duct.
  • the second sheet metal part 3 is bent at a right angle and is first used to produce the fold connection with its folded edge into the through an S-bend of the first Sheet metal part 2 formed pocket inserted.
  • a sheet metal edge 4 of the first sheet metal part 2 protruding from the second sheet metal part 3 is bent in the direction of an arrow 5 toward the second sheet metal part 3 and pressed onto the latter.
  • the resulting seam connection is shown in Fig. 3.
  • This known folding closing machine 1a is equipped with a pair of drive rollers 6a, 7a, which bear against the sheet metal edge 4 under pressure from opposite sides. Driven by an electric motor, the drive rollers 6a, 7a move the seaming machine 1a in the feed direction, that is, in the longitudinal direction of the sheet metal edge 4.
  • the drive rollers 6a, 7a, trailing in the direction of advance, are provided on the seaming machine 1a with a pair of form rollers, not shown, whose roller gap compared to that shown in FIG. 1 shown starting position of the sheet metal edge 4 is inclined towards the second sheet metal part 3 and encloses an acute angle with it.
  • a sliding block 8a is provided on the end face facing the pair of form rollers with an inclined surface.
  • the fold closing machine 1a is attached to the sheet metal edge 4 of the first sheet metal part 2 in the position shown in FIG. 4.
  • the drive rollers 6a, 7a pull the seaming machine 1a along the sheet metal edge 4 in the feed direction.
  • the part of the sheet edge 4 emerging from the roller gap of the drive rollers 6a, 7a runs into the roller gap of the pair of forming rollers and is thereby bent towards the second sheet metal part 3 in accordance with the inclination of this roller gap.
  • the sliding block 8a lagging the pair of form rollers presses the sheet edge 4, which, after leaving the roll gap of the pair of form rollers, inclines at an acute angle against the second sheet metal part 3 onto the surface of the second sheet part 3 in the position shown in FIG. 3.
  • a support 9a with a support roller 10a counteracts this unwanted tearing of the folding closing machine 1a from its intended movement path.
  • the latter rolls with a tapered edge 11a on the first sheet metal part 2 during the advancing movement of the folding closing machine 1a and thereby engages with the edge 11a in a groove-like longitudinal recess of the first sheet metal part 2 which was created during the folding.
  • the support roller 10a accordingly forms an abutment for the seaming machine 1a, by means of the seaming machine 1a is prevented from leaving its intended path of movement.
  • the folding closing machine 1 makes use of a first driven pair of shaped rollers 12, consisting of conical shaped rollers 13, 14, a second pair of shaped rollers 15 with likewise driven and conically shaped shaped rollers 16, 17, as well as a pressure roller 18, for producing the folded connection.

  • the roller gap 22 is inclined more towards the plane of the second sheet metal part 3 than the roller gap 20 previously run through by the sheet metal edge 4.
  • the roller gap 22 forms an acute angle 23 with the plane of the second sheet metal part 3, which is approximately half the size of the acute angle 21 between the central axis of the roller gap 20 and the plane of the second sheet metal part 3.
  • the sheet edge 4 which is then inclined at an angle 23 against the plane of the second sheet metal part 3, is acted upon by the pressure roller 18 and pressed onto the surface of the second sheet metal part 3 into its final bending position, in which the fold connection is closed.
