Definitions

  • the present invention relates to a new process for combining operations industrial cutting and profiling, preferably in line.
  • the invention also relates to tools rotary allowing the implementation of the process.
  • One of the techniques for making walls having acoustic sound absorption properties is based on the use of profiled metal siding whose surface has many orifices.
  • the processes current consist in using either perforated profiles, usually round holes of small diameter, i.e. still profiles in which we made punctures.
  • the punctures are partial cuts leaving the waste cutting attached to the sheet, these cuts being generally rectangular in shape.
  • the profiles mentioned above are characterized by a cutting density very large, on the order of several thousand holes per square meter.
  • profiling figures prominently. In this case also we must combine operations of cutting and profiling. The number of cuts, lower that in the case of profiles with acoustic function, remains however very important.
  • Press cuts can be performed before the profiling operation, outside the profiling line, or by a press installed in the profiling line or even after the operation of profiling.
  • Rotary tools offer an alternative interesting to the use of presses, in that they can operate at speeds compatible with that of the profiling line.
  • an alternative practiced in this case is the puncture which consists in making a partial cut, leaving the waste attached to the sheet, allowing to eliminate the problem of its evacuation.
  • This operation can be performed by rotary tools but present then other disadvantages.
  • the lower knives being discs, a quality cut is only obtained according to the direction parallel to the advance of the sheet, the side perpendicular being rather torn off, which can deteriorate corrosion behavior.
  • the waste remaining attached to the sheet prohibits the presence of punctured in areas in contact with rollers profiling, which significantly reduces the relative surface profile in which you can actually practice these punctures.
  • the angle of the waste relative to the plane of the sheet is closer to 45 ° than 90 ° which reduces substantially the apparent opening. Functional profiles acoustics made using the puncture technique then have performances significantly lower than those made by drilling.
  • the present invention aims to provide a solution to overcome the disadvantages of the state of the art.
  • the present invention aims to offer a rotary tool technology allowing either cutting many small holes online profiling, that is to say punctures of geometry improved and without penalizing the profiling speed.

  • the first pair of rotary tools is cutting in the transverse direction with respect to sheet metal advance for making notches
  • second pair of rotary tools is sharp in the longitudinal direction with respect to the advance of the sheet. Note that the role of the two pairs of tools can be inverted (cut first in the longitudinal direction, then transverse).
  • the final cut being essentially rectangular and punctured
  • said first pair of tools is sharp on three contiguous sides of said rectangle and said second pair of tools is foldable by relation to the axis formed by the fourth side of said rectangle.
  • said rotary tools are mounted on shafts supported by bearings whose axis is perpendicular to the direction of advance of the sheet.
  • the direction of rotation of the upper and lower tools is such that speed tangential of said tools at the point of contact with the sheet metal has the same meaning and essentially the same value as the sheet speed.
  • said device comprises means for ensuring the relative positioning according to the circumference of teeth belonging to the upper and lower tools of said first pair of circular tools, said means being preferably a backlash gearbox synchronizing the trees.
  • the first pair of tools includes a top tool, consisting of a succession alternative of elementary circular knives and dividers, and a lower tool, consisting of a alternative succession of elementary circular knives and elements acting as side knives.
  • the second pair of tools includes a top tool and a lower tool, each consisting of a succession alternative of elementary circular knives and interlayers.
  • each circular knife upper elementary has teeth at its periphery, whose arc has an equivalent length, to the games of cut close to the distance between the two notches belonging to the same final cut and produced by the first pair of tools.
  • Circular knives elementary, as well as the dividers of the second pair of tools have equivalent widths, essentially with the cutting games close.
  • the device of the invention is advantageously provided with means to facilitate the removal of cutting waste, preferably combs whose teeth are inserted between the tools elementary circulars of the second pair of tools.
  • the upper tool of the second pair of tools can be fitted with teeth which are rounded or softened at the bend edge and having games compatible with folding.
  • the process of the invention can combine, on the same machine, cutting and puncturing operations, distributed according to sheet metal strips parallel to the advancement of the sheet metal, said punctures being made in areas which do not enter in contact with profiling tools.
  • said cuts pierced or punctured rectangular are offset, the offset between two adjacent cuts being equal to the pitch in length (Plg) divided by an offset parameter X, X being non-zero.

  • the second pair makes longitudinal cuts and ensures easy disposal of waste.
  • the first pair of knives for example, cuts on three sides.
  • the second pair then folds the cutting waste, which allows to obtain a clearly visible opening improved over the state of the art.
  • Figure 1 shows an overview of the system.
  • a first pair of rotary tools composed of tools 1 and 2, mounted respectively on shafts 6 and 6 ', performs a partial cut on the sheet, without waste removal.
  • the cutting is completed by a second pair of tools, consisting of tools 3 and 4, mounted respectively on 6 '' and 6 '' shafts.
  • These trees are supported by bearings mounted in similar heads to the profiling heads (not shown).
  • the meaning of rotation of each tool is indicated (B, B ', B' ', B' ').
  • the advancement of the sheet is done in direction A, in the direction indicated and is equivalent to the peripheral speed common tools 1, 2, 3 and 4.
  • Figures 2 and 3 show a form of preferential production of rotary tools 1 and 2.
  • figure 2 shows the two tool elements upper 11 and lower 21 circular forming a notch 7 perpendicular to the direction of travel of the sheet 5 (see Figure 5).
  • the upper tool 1 consists of a stack of tools elementary circulars 11 and dividers 12. These tool elements are mounted on the shaft 6, positioned and blocked on the shaft in the direction of rotation by elements such as keys. These are also locked in the axial direction so as to guarantee precise positioning.
  • the lower tool 2 consists of analogous to a stack of elements 21, being opposite elements 11 and separated by elements 22 which act as side knives when cutting the notch 7.
  • the elements 21 and 22 are blocked in rotation and positioned in the axial direction, as for tool 1.
  • the elements 11, 21 and 22 are preferably made in heat treated tool steel, as for classic cutting tools.
  • This mode of construction of rotary tools is particularly advantageous because it allows a realization economical tools, items like 11 or 21 can be made by cutting a stack of treated tool steel discs.
  • Axial positioning of tools 1 and 2 is achieved by stops mounted on the shafts at level of the bearings located in the support head.
  • the relative radial positioning of tool teeth circulars 11 and 21 is produced by at least one box gears synchronizing the shafts 6 and 6 '. It is preferably backlash gears, so that guarantee precise positioning compatible with games cutting.
  • At least one of the 6 or 6 'shafts is motorized so as to guarantee a circumferential speed of rotation tools equal to the advance of sheet A.
  • Figure 4 shows two embodiments teeth 111 or 111 'of the circular tool 11.
  • the sheet After passing through the first pair of tools rotating, the sheet has notches 7 as indicated in the figure 5.
  • Figures 6 and 7 show the knives elementaries 31 and 41 performing the second operation of cutting.
  • the circular knife 31 has at its periphery teeth 311, the arc of which has an equivalent length close to the cutting clearances, the distance between two notches 7.
  • the complete upper circular tool 3 is produced by a stack of elementary knives 31 separated by dividers 32. Positioning circumferential and axial of the knives 31 is made of similar to that of tools 1 and 2.
  • the shaft 6 '' is synchronized with respect to shaft 6 so that guarantee the precise positioning of the notches 7 by compared to knives 311. This synchronization is by example produced by a gear system.
  • Tool 4 consists of a stack of elementary cutting discs 41 and spacers 42 ( Figure 7). Their axial positioning is achieved as for tools 1 and 2, the relative positioning of the tools 3 and 4 must be guaranteed only in the direction axial.
  • the tool elements 11, 21 and 31 as well as the dividers 42 have equivalent widths, to the sets of cut close.
  • Cutting waste is very easily evacuated between the discs 41, there is possibly a comb whose teeth are inserted between the discs 41 to guarantee the evacuation of any remaining waste wedged between the cutting discs 41, the waste being then evacuated transversely, for example using a conveyor belt.
  • Figure 8 shows schematically a optimized positioning of the cuts. Indeed a point delicate process is the cutting effort to be provided, particularly when cutting the notches by the tools 1 and 2. To reduce this effort, it is thus interesting to offset the cuts as presented in the figure 8.
  • the parameters to be considered are presented at FIG. 9: the transverse step Ptr, the long step Plg, DecTr cross cutting and DecLg long cutting.
  • the cutting rate a parameter determining for example the acoustic quality of the panels, is the ratio between the cut surface (DecTr x DecLg) and the step surface (Plg x Ptr).
  • the parameter X determining the offset is chosen high enough to reduce stress on trees. In effect the higher the parameter X, and in particular if X is not whole, the less cuts are made simultaneously.
  • Another important parameter is the ratio between the length not cut in length, Plg - DecLg, and the no lag, Plg / X. If this report is whole, some first cuts of rectangular openings coincide with the second cutouts offset by a number of rows equal to said report. In this case, the number of cuts taking place simultaneously is relatively high, which gives a relatively large load in bending of trees, but the cuts being made in pairs, the radial forces on the knives offset each other, which reduces the torque applied to the trees. If we choose the cutting parameters so that this ratio (Plg - DecLg) / (Plg / X) is not an integer, we reduce the number cutting takes place simultaneously, which reduces the bending force, but increases the torque applied to trees.
  • Table 1 shows an example of choice adequate parameters corresponding to a non-integer report and FIG. 10 illustrates a concrete example of cutting.
  • the technique of the invention also allows optimize the cutting of openings in punctured mode, say without removing material.
  • Tool technology is in its identical principle. At the first pair of tools 1 and 2, we performs a U-shaped cutout as shown in 7 ' (longitudinal direction) or 7 '' (transverse direction) to Figure 11. The type 111 teeth of the elementary tool 11 are adapted accordingly. On the second pair tool, we no longer cut, as before, but folding according to 8 or 8 '. Tool teeth 311 elementary 31 are of course adapted accordingly: rounded at the folding edge and compatible clearances with folding. Figure 12 shows typical views of this type of puncture, for the longitudinal direction and for the transverse direction.
  • the tool diameter will be conditioned by considerations resistance of the materials that govern the sizing of trees, but also by contact conditions of the circular tool with the sheet. So the radius of tools 1 and 2 will preferably be equal or greater than 100 times the thickness of the sheet. In the case of flat, we can also choose different spokes for tools 3 and 4, tool 4 having for example a radius significantly greater than tool 3, so that guarantee good support of the sheet during the operation of folding.
