Definitions

the invention relates to a device for roll forming of sheet metal, in particular for the production of straight or conical sheet metal parts as roofing and / or wall cladding elements, with both sides of a transport path of the sheet to be processed by the machine arranged rows of pairs of forming rollers, of which one of the form rollers the Sheet from the top and one from below and thus form, the rows of forming rollers are adjustable in their mutual distance and adjustable with respect to the transport direction of the sheet at an angle.
roofing sheets are used, which are provided at their side edges with folds, where they are connected to adjacent sheets and fixed to the roof substructure.
the devices mentioned above are used for roll forming the side edges of the sheets.
rectangular sheets are roll-formed on the side edges.
the present invention has for its object to improve the roll former of the type mentioned in such a way that they allow for the use of problematic sheet material error-free production of Thisfalze the sheet metal parts.
the object is achieved with a device for roll forming of sheet metal, in particular for the production of straight or conical sheet metal parts as roofing and / or wall cladding elements, arranged on both sides of a transport path of the sheet to be machined by the machine rows of pairs of forming rollers, one of which Form rollers to act on the sheet from above and one from below and thereby forming, the rows of forming rollers in their mutual distance adjustable and with respect to the transport direction of the sheet at an angle adjustable, which is characterized in that the rows of pairs of forming rollers upstream on both sides of the Transport path of the sheet is arranged a longitudinal cutting device for the sheet, wherein the longitudinal cutting means are adjustable independently of the rows of pairs of forming rollers in their mutual distance adjustable and at an angle to the transport direction of the sheet.
the wall thickness and the quality of the sheet it can be roll-formed with varying degrees of ease, since the factors mentioned above influence the so-called flowability of the sheet.
the properties of the sheet may vary in a withdrawn from a coil sheet metal over its length.
errors in the production of Sofalze therefore occurred when using problematic starting material for the sheet metal parts.
the device according to the invention such problems can be at least partially compensated by, for example, a sheet with poor flow properties with a small oversize cut to the form roller pairs is supplied. A modification of the trimming of the side edges of the sheet is still possible during production.
the angle of incidence of the longitudinal cutting devices can be adjusted by means of a corresponding sensor device much more precisely to the angle of attack of the forming rollers, as is possible in the known systems.
a slight deviation of the angle of incidence of the longitudinal cutting devices from the angle of attack of the forming rollers may be desirable in certain cases and can be adjusted in the device according to the invention.
the longitudinal cutting devices are each arranged on a carrier, wherein the carrier is symmetrical and / or asymmetrical to the center line of the transport path by a drive device which is independently controlled by the drive or the devices for the pairs of forming rollers, movable.
a symmetrical adjustment of the slitters to the center line of the transport path result in isosceles conical sheets.
An asymmetric adjustment allows the production of sheets with inclined side edges at different angles. It may also be a side edge of the sheet metal part produced straight and the other inclined. Due to the completely independent controllability of the carrier with the longitudinal cutting devices, these can also be moved completely out of the transport path of the sheet, which facilitates the feeding of already cut sheet metal to the forming rollers.
the longitudinal cutting devices can be formed in a conventional manner by pairs of cutting rollers.
either all pairs of forming rollers of a row can be arranged on a common support or it can be provided a plurality of carriers, each carrying a pair or more pairs of forming rollers. If the pairs of forming rollers of a row are distributed over a plurality of carriers, not only conical plates but also plates with a width that does not vary continuously can be produced. The sheet-metal parts can then also have a region which initially tapers conically and then subsequently a region which widens again and / or a region of constant width. However, if only strictly conical sheets are to be produced, the arrangement of all the pairs of form rollers on one side on a common carrier is the simplest drive technology solution.
the longitudinal cutting devices can be moved synchronously and / or with a time offset from the pairs of shaping rollers.
a staggered movement of the longitudinal cutting means is particularly useful when setting the machine on a new sheet metal blank.
the slitting devices can then be adjusted exactly to the already set pairs of form rollers. During the manufacture of the sheet metal parts, a synchronous movement of the longitudinal cutting devices to the forming roller pairs is then meaningful.
the device can be fed already cut sheet metal plates and / or drawn from a coil sheet metal web.
the forming roller pairs crushing devices for the separated by the longitudinal cutting devices sheet metal strip.
the crushed metal strips are collected in arranged below the crushing device waste containers and can then be easily disposed of.
the single FIGURE shows a schematic top view of a roll former 10, which has two supports 11, 12, on each of which four pairs of mold rolls 13, 14, 15, 16 and 17, 18, 19, 20 are arranged.
the form roller pairs 13 to 16 and 17 to 20 include between them a transport path for a sheet not shown here, in the edges of which form a profile.
the carriers 11, 12 are pivotally mounted about axes 21, 22.
For the guidance of the pivotal movement of the carrier 11, 12 are on the axes 21, 22 opposite end of the carrier 11, 12 arcuate guides 23, 24 are arranged.
the carriers 11, 12 for the production of conical plates in each case by the angle ⁇ relative to the direction indicated by an arrow 25 transport direction of the sheet, which also corresponds to the direction of the center line 26 of the roll former 10, inclined.
the rest Carrier 11, 12 In order to move the carrier 11, 12 during the manufacture of the sheets on the center line 26 and then back away from this, the rest Carrier 11, 12 on two transverse guides 27, 28 along which they are movable by means of motors 29, 30 driven by spindles 31, 32 transversely to the center line 26.
a separate spindle 31, 32 and a separate motor 29, 30 are provided for each carrier 11, 12, whereby it is possible to produce asymmetric plates.
the beams 11, 12 can be independently adjusted in their angles to the center line 26 and in their distance from the center line 26. If only isosceles conical plates are to be produced, only one spindle and one motor could be provided for both carriers 11, 12.
the carriers 11, 12 with the forming roller pairs 13 to 16 and 17 to 20 in the transport direction 25 of the sheet are preceded by two further carrier 33, 34 are provided, on each of which a longitudinal cutting device 35, 36 is arranged.
the carriers 33, 34 are pivotable about axes 37, 38. The pivotal movement is also controlled in the carriers 33 and 34 by arcuate guides 39, 40.
the angle ⁇ , which enclose the carrier 33, 34 with the center line 26 of the roll former 10, in the example shown corresponds exactly to the angles ⁇ of the carrier 11, 12, which is not mandatory for all applications.
the distance of the carrier 33, 34 to the center line 26 can be adjusted via motors 41, 42, each of which drives spindles 43, 44. For this rest, the carrier 33, 34 on a transverse guide 45th
the motors 41 and 42 may or may not be synchronized with the motors 29 and 30 of the carriers 11, 12.
the longitudinal cutting devices 35, 36 can be positioned much more accurately than in the case of known roll formers with longitudinal cutting devices arranged on the carriers of the forming roller pairs.
