Definitions

  • the present invention relates to a device comprising rotary cutting tools for joint operation cutting and profiling, preferably in line, according to the preamble of claim 1.
  • the invention also relates to processes for joint implementation of cutting operations using the device of the invention, and the use of such a device.
  • One of the walls realization techniques exhibiting acoustic sound absorption properties is based on the use of profiled metal siding whose surface has many orifices.
  • profiling figures prominently. In this case also we must combine operations of cutting and profiling. The number of cuts, lower in the case of acoustic function profiles, remain however very important.
  • Press cuts can be carried out before the profiling operation, outside the line of profiling, 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 punctured 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 achieved by rotating tools but present then other disadvantages.
  • the lower knives being discs, a quality cut is obtained only according to parallel direction in advance of the sheet, the side perpendicular being rather torn off, which can deteriorate the corrosion behavior.
  • waste remaining attached to the sheet prevents the presence of punctures in areas in contact with pebbles profiling, which significantly reduces the relative area the profile in which one can actually practice these punctures.
  • the angle of the waste with respect to the plane of the sheet is closer to 45 ° than 90 ° which reduces substantially the apparent opening. Functional profiles acoustics made on the basis of the technique of the flat then have significantly lower performance than those made by drilling.
  • US Pat. No. 4,766,707 discloses a machine comprising a first pair of rotary drums drilling followed by a second pair of rotary drums cutting a metal strip. According to the installation this machine is followed by a forming machine or folding to make clips for roof panels.

  • the final cut being essentially rectangular
  • the first pair of rotating tools is cutting in the transverse direction with respect to the advance of the sheet metal for making notches and the second pair of rotary tools is cutting in the longitudinal direction relative 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 transversal).
  • the final cut being essentially rectangular and flat type
  • said first pair of tools is cutting on three contiguous sides of said rectangle and said second pair of tools is folding by relative to the axis constituted 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 the 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 is of the same meaning and essentially of the same value as the scroll speed of the sheet.
  • 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 gear box with play catch-up synchronizing the trees.
  • the first pair of tools includes a superior tool, consisting of a succession alternative elementary circular knives and of inserts, 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 superior tool and a lower tool, each consisting of a succession alternative elementary circular knives and interlayers.
  • each circular knife elementary element has teeth at its periphery, arc whose length is equivalent to the games of cut close, at the distance between the two notches belonging to the same final cut and made by the first pair of tools.
  • Circular knives as well as the dividers of the second pair of tools have equivalent widths, basically to cutting games near.
  • the device of the invention is advantageously provided with means for facilitating the disposal 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 provided with teeth that are rounded or softened at the bending edge and having games compatible with folding.
  • the method of the invention can combine, on the same machine, cutting and puncturing operations, distributed according to sheet metal strips parallel to the progress of the sheet, said punctures being made in areas not entering in contact with profiling tools.

  • the cut 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 indicated direction and is equivalent to the peripheral speed common tools 1, 2, 3 and 4.
  • Figures 2 and 3 show a shape of preferred embodiment of rotary tools 1 and 2.
  • Figure 2 shows the two tool elements upper circular 11 and lower 21 realizing a notch 7 perpendicular to the direction of advancement of the sheet 5 (see Figure 5).
  • the upper tool 1 consists of a stack of tools elementary circulars 11 and inserts 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 elements are also blocked in the axial direction so as to guarantee a precise positioning.
  • the lower tool 2 consists of analogous way of a stack of elements 21, lying vis-à-vis the elements 11 and separated by elements 22 which act as side knives when cutting the notch 7.
  • the elements 21 and 22 are locked in rotation and positioned in the axial direction, as for tool 1.
  • the elements 11, 21 and 22 are preferably made in a heat-treated tool steel, as for the conventional cutting tools.
  • This mode of construction of rotary tools is particularly advantageous because it allows a realization economic tools, items such as 11 or 21 can be made by wire cutting a stack of steel discs with a treated tool.
  • Axial positioning of tools 1 and 2 is achieved by stops mounted on the trees at level of the bearings in the support head.
  • the Relative radial positioning of the teeth of the tools circular 11 and 21 is made by at least one box to gears synchronizing the shafts 6 and 6 '. It is preference of gears with catch-up clearance, so as to guarantee precise positioning compatible with the games cutting.
  • At least one of the trees 6 or 6 ' is motorized from to guarantee a circumferential rotation speed tools equal to the advance of sheet A.

  • the tree 6 '' is synchronized with respect to the shaft 6 so as to guarantee precise positioning of the notches 7 by compared to knives 311. This synchronization is by example made by a gear system.
  • the tool 4 consists of a stack of elementary cutting discs 41 and inserts 42 ( Figure 7). Their axial positioning is realized as for tools 1 and 2, the relative positioning of tools 3 and 4 must be guaranteed only in the direction axial. Tool elements 11, 21 and 31 as well as tabs 42 have equivalent widths, at the games of cut close.
  • the cuttings waste is very easily evacuated between the disks 41, a possible comb with teeth interposed between discs 41 to ensure the evacuation of waste that would remain wedged between the cutting discs 41, the waste being then evacuated transversely, for example using a conveyor belt.
  • Figure 8 schematically presents a optimized positioning of the cutouts. Indeed a point delicate of the process is the cutting effort to be provided, especially when cutting the notches by the tools 1 and 2. To reduce this effort, it is thus interesting to stagger the cutouts as presented to the figure 8.
  • the parameters to be considered are presented in FIG. 9: the transverse pitch Ptr, the pitch length Plg, the DecTr transverse cut and the DecLg long cut.
  • the cutting rate which determines, for example, the sound quality of the panels, is the relationship between the cut surface (DecTr x DecLg) and the surface of the steps (Plg x Ptr).
  • the parameter X determining the shift is chosen high enough to reduce the stress on the trees. In effect plus the parameter X is high, and especially if X is not complete, the fewer cuts are made simultaneously.
  • Another important parameter is the ratio between the length not cut in length, Plg - DecLg, and the no offset, Plg / X. If this report is complete, some first cuts of rectangular openings coincide with the second cuts 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 made in pairs, the radial forces on the knives compensate each other, which reduces the torque applied to the trees. If we choose cutting parameters so that this ratio (Plg - DecLg) / (Plg / X) is not an integer, we reduce the number cuts occurring simultaneously, which decreases the bending force, but increases the torque applied to trees.
  • Table 1 presents an example of choice adequate parameters corresponding to a non-integer ratio and Figure 10 illustrates a concrete example of cutting.
  • the technique of the invention also allows to optimize the cutting of openings in flat mode, it's up to say without removal of material.
  • the diameter of the tools will be conditioned by the considerations of resistance of the materials that govern the dimensioning of trees, but also by contact conditions of the circular tool with the sheet.
  • the radius of the tools 1 and 2 will preferably be equal or greater than 100 times the thickness of the sheet.
