    Description


    [0001] The present invention relates to a machine to process section bars according to the preamble of claim 1 (see for example DE 38 23 635 A1).

    [0002] In the field of processing of section bars, in particular made of aluminium, light alloys, PVC or the like, it is known to provide a machine of the type comprising an elongated base, at least one processing station mounted along the base and a feeding unit designed to hold the section bar at a rear end thereof and to feed it along the base and through the processing station.

    [0003] The machine further comprises two roller support devices, which are mounted in succession along the base and define a support surface for the section bars.

    [0004] Each roller support device has a plurality of rollers mounted to rotate about respective rotation axes, which are substantially parallel to each other and transverse to a forward direction of the section bars along the base. Generally, the processing station is provided with a cutting device to cut the section bar into two pieces, and an operating head for milling and/or punching operations in the pieces.

    [0005] During the processing carried out by the cutting device and the operating head, the section bar and the pieces are normally held by at least two vices mounted at the processing station and moving along the base.

    [0006] When the section bar has a shaped cross-section, e.g. an L-shaped cross-section, and is arranged on the support surface on its thickness, the section bar is kept stable on the support surface by means of at least one clamping device to allow the cutting device and the operating head to perform the corresponding cutting, milling and/or drilling operations correctly.

    [0007] The known machines to process section bars of the type described above have some drawbacks, mainly due to the fact that the clamping device has a variable configuration and is manually assembled and disassembled by the personnel depending on the geometrical characteristics of the section bars.

    [0008] Consequently, the machine must be equipped with a relatively large number of clamping devices, has relatively long service times and is therefore relatively expensive. The object of the present invention is to provide a machine to process section bars that is free from the aforesaid drawbacks and is simple and inexpensive to implement. According to the present invention, it is provided a machine to process section bars as claimed in the appended claims.

    [0009] The present invention will now be described with reference to the accompanying drawings, showing a non-limiting embodiment, wherein:

    Figure 1 is a schematic perspective view, with parts removed for clarity's sake, of a preferred embodiment of the machine to process section bars according to the present invention;

    Figure 2 is a schematic perspective view, with parts removed for clarity's sake, of a detail of the machine of Figure 1;

    Figure 3 is a first schematic side view, with enlarged parts and parts removed for clarity's sake, of the detail of Figure 2; and

    Figure 4 is a second schematic side view, with parts removed for clarity's sake, of the detail of Figure 2.



    [0010] Referring to Figure 1, 1 indicates as a whole a machine to process section bars 2, in particular made of aluminium, light alloys, PVC or the like, having an elongated shape. The machine 1 comprises an elongate base 3, which extends in a horizontal direction 4 and is provided with a longitudinal guide rail 5 parallel to the direction 4.

    [0011] The machine 1 further comprises two roller support devices 6, 7 mounted in succession along the base 3. Each device 6, 7 has a plurality of rollers 8, which are mounted to rotate about respective rotation axes 9, substantially parallel to each other and to a horizontal direction 10 transverse to the direction 4, and which define a support surface P for at least one section bar 2.

    [0012] Each roll 8 is movable in a vertical direction 11, orthogonal to the directions 4 and 10 between a raised operating position and a lowered rest position.

    [0013] The machine 1 is further provided with a loading station 12 of the section bars 2 to be processed on the device 6 and with an unloading station 13 of the section bars 2 just processed by the device 7.

    [0014] Each station 12, 13 comprises a belt conveyor 14, which faces the respective device 6, 7 in the direction 10, and includes, in turn, a plurality of conveyor belts 15, which are parallel to each other and to the direction 10.

    [0015] The machine 1 further has a processing station 16, which is formed along the base 3 between the stations 12, 13, and extends between the devices 6, 7.

    [0016] The section bars 2 are fed along the plane P and through the station 16 in the direction 4 by a feeding device 17, comprising a first horizontal slide 18 slidably coupled to the longitudinal guide rail 5 to move straight along the longitudinal guide rail 5 in the direction 4 with respect to the base 3; a second horizontal slide 19, slidably coupled to the horizontal slide 18 to move straight in the direction 10 with respect to the horizontal slide 18; and a vertical slide 20, slidably coupled to the horizontal slide 19 to move straight in the direction 11 with respect to the horizontal slide 19.

    [0017] The vertical slide 20 has an elongated shape, extends in the direction 4 and supports a holding element 21 connected to a free end of the vertical slide 20.

    [0018] The element 21 is rotatably coupled to the vertical slide 20 to rotate, relative to the vertical slide 20, about an axis of rotation (not shown) parallel to the direction 4, and comprises two (not shown) jaws movable between a clamping position and a release position of the section bars 2.

    [0019] The station 16 is provided with a drilling and/or milling assembly 22 comprising an annular chassis 23, which is mounted between the stations 12, 13 and extends around a feeding path of the section bars 2; and a plurality of tool spindles 24, which are mounted parallel to the directions 10 and 11, each of them being designed to receive and retain a respective drilling and/or milling tool of a known type and not shown type.

    [0020] The spindles 24 are mounted on the chassis 23 by interposing a cross slide 25, which has an annular shape and is designed to allow the spindles 24 to move relative to the base 3 in the directions 10 and 11.

    [0021] The spindles 24 parallel to the direction 10 (hereinafter referred to as 24a) are coupled to the cross slide 25 to move, relative to the cross slide 25, independently of one another in the direction 10; and the spindles 24 parallel to the direction 11 (hereinafter referred to as 24b) are coupled to the cross slide 25 to move, relative to the cross slide 25, independently of one another in the direction 11.

    [0022] The station 16 is further provided with an overhead crane 26, which is mounted between the milling assembly 22 and the station 13 and is movable relative to the base 3 between the devices 6, 7 and the stations 12, 13 in the direction 4.

    [0023] The overhead crane 26 comprises a horizontal crossbar 27, which extends above the plane P in the direction 10, supports a cutting device 28 for cutting each section bar 2 into two pieces (not shown) and further supports a drilling and/or milling device 29 to drill and/or mill the adjacent ends of the pieces (not shown).

    [0024] The device 28 is provided with a circular cutting blade 30, which is mounted to rotate about its own longitudinal axis and is movable with respect to the crossbar 27 in the directions 10 and 11 and about an axis of rotation 31 parallel to the direction 11.

    [0025] The device 29 is provided with a drilling and/or milling head 32 movable with respect to the crossbar 27 in the directions 10 and 11.

    [0026] As shown in FIGS. 2 and 3, the station 16 is provided, in this case, with four holding devices 33, 34, wherein the device 33 is fixed in the direction 4 and the devices 34 are movable along the base 3 in the direction 4.

    [0027] Each device 33, 34 comprises a horizontal clamping vice 35, comprising two jaws 36 perpendicular to the direction 10 and mutually movable in the direction 10 between a clamping position and a release position of at least one section bar 2.

    [0028] Each device 33, 34 further comprises a vertical clamping vice 37, comprising two jaws 38 perpendicular to the direction 11 and mutually movable in the direction 11 between a clamping position and a release position of at least one section bar 2.

    [0029] Each lower jaw 38 comprises a flat plate defining a support surface A for the section bars 2 and is provided with a plurality of pneumatic nozzles 39, each of which opens up outwards at the surface A and is designed to generate an air jet 40, which is sloping with respect to the surface A and has a component 41 parallel to the surface A.

    [0030] The components 41 of the jets 40 allow removing from the surfaces A of the lower jaws 38 machining chips and/or scraps produced by the milling assembly 22, by the cutting device 28 and by the drilling device 29 and left on the lower jaws 38 to avoid any damage to the section bars 2 when the clamping vices 37 are in their clamping positions. Each nozzle 39 includes, in this case, a housing hole 42 provided through the relative lower jaw 38 perpendicular to the surface A; and a diffuser 43, inserted in the hole 42 and in turn comprising a narrower lower portion 44 having a diameter smaller than the one of the hole 42 and an enlarged upper portion 45 having a diameter substantially equal to the diameter of the hole 42.

    [0031] Each nozzle 39 further comprises a ramp 46, which is formed on the relative lower jaw 38, is sloping with respect to the relative surface A and cooperates with the portion 45 of the relative diffuser 43 to correctly orient the respective jet 40.

    [0032] The nozzles 39 of each vice 37 are pneumatically fed by a supply manifold 47, which is obtained through the lower jaw 38 and is connected to a compressed air pneumatic device (not shown).

    [0033] Referring to Figures 2 and 4, when the section bar 2 has a shaped form, e.g. is L-shaped, and is arranged on the surface A on its thickness (Figure 2), each device 33, 34 cooperates with a lower support device 48 comprising, in this case, a horizontal slide 49, which is mounted below the relative lower jaw 38 and is movable relative to the lower jaw 38 and under the thrust of an operating device 50 in the direction 10.

    [0034] The device 48 further comprises a vertical slide 51, which extends in the direction 11 and is movable relative to the slide 49 and under the thrust of an operating device 52 mounted on the slide 49 in the direction 11.

    [0035] The slide 51 has two parallel appendages 53, each of which extends in the direction 11 and is provided, in this case, with a wheel 54 mounted on the relative appendage 53 to rotate about an axis of rotation 55 parallel to the direction 10.

    [0036] The wheels 54 are moved from the slide 51 in the direction 11 between a lowered rest position, in which the wheels 54 are arranged below the surface A, and a raised operating position, in which the appendages 53 extend through the relative lower jaw 38 and protrude above the surface A to support the section bar 2 on the lower side (Figure 2). When the wheels 54 move into their raised operating position, each appendage 53 slidably engages a feeding channel 56 obtained through the relative lower jaw 38 in the direction 10.

    [0037] According to some variants not shown, the wheels 54 are removed and replaced with respective low-friction sliding members or with an air flotation table.

    [0038] The lower support devices 48 therefore allow keeping stable the section bars 2 at the processing station 16 to ensure a proper operation of the milling assembly 22, of the cutting device 28 and of the drilling and/or milling device 29.
