    lO SUPPORT TABLE FOR A PROCESSING MACHINE FOR SHEET MATERIALField of the invention The present invention relates to a support table for a processing machine for sheet material,particularly a bending machine for sheet material, of the type defined in the preamble of claim 1 .Background of the invention The upper surface of the support table for a processing machine for sheet material is providedWith, in the feeding direction of a piece of sheet metal to be processed, a plurality ofadjustable and tiltable protruding main stop elements. Said main stop elements being arrangedat the support table so as to enable individual adjustment of each main stop element toincrease the eXactness of the position of a leading edge of the piece of sheet metal relative to aprocessing line defined by a processing station of said processing machine. The main stopelements are in their normal position upraised from the surface of the support table by biasing means. At the leading edge of the support table possible second stop elements are arranged.
    Moreover, each main stop elements should be able to be tilted individually to such an extentthat an upper edge of respective main stop element is positioned flush With the surface of thesupport table, When the piece of sheet metal is placed on the support table, and thus to formno obstacle When the piece of sheet metal is advanced in the feeding direction on the support table, but to obstruct any movement of the piece of sheet metal in the opposite direction.
    Support tables for processing machines for sheet material of the above-mentioned type are known from the prior art. See US 2008/0072648 A1, for instance.
    HoWever, one problem With support tables of the above-mentioned type is that the individualstop elements are gauged at the factory and during transportation and over time the gauging ofsaid stop element may change, particularly of the main stop elements, thus jeopardizing the quality of the finished products.
    Another problem With support tables of the above-mentioned type is that the end of the main stop elements abutting the edge of the piece of sheet metal to be processed is not lO perpendicular to said edge, Which means that the edge of the Work piece may abut on the endof individual stop elements at different heights. Moreover, this effect Will be further increased due to how the main stop elements are adjusted in the prior art.
    Also the height of the end of respective main stop element abutting the edge of the piece ofsheet metal to be processed is often too low in case said edge of the piece of sheet metal has a curving, Which necessitates the use of main stop elements With rather high abutment end.
    Accordingly, an object of the present invention is to provide a support table having at leasttwo main stop elements for a processing machine for sheet material, on Which support table itis easy to exactly line up/ gauge a Work piece/piece of sheet metal in a fixed relation relative to a processing line defined by a processing station of said processing machine.
    Another object of the present invention is to provide a support table, the main stop elementsof Which have an abutment end that is perpendicular to the surface of the support table and thus to a trailing edge of the piece of sheet metal to be processed.
    Yet another object of the present invention is to provide a support table, the main stopelements of Which are arranged to pop-up from the surface of the support table to a lager height that is achieved With the main stop elements of the prior art support tables.
    With the inventive support table it Will also be easier for the aftermarket to adjust said main stop elements.Summary of the invention This object is achieved according to the invention by a support table for a processing machinefor sheet metal, said support table being arranged for supporting a piece of sheet metal duringa processing operation, Wherein said support table comprises at least one support frame,Wherein said support frame supports at least one first pivotably arranged stop element andbeing provided With a first adjustment device arranged for a first adjustment of the position ofsaid support frame and thereby said main stop element back and forth relative to said supporttable and in a feeding direction of said piece of sheet metal, said main stop elements beingarranged to place said piece of sheet metal on said support table in a fixed relation to a processing station of said processing machine, characterized in that each of said main stop lO element is further provided With a second adjustment device arranged for a second adjustmentof the position of said main stop element back and forth in the feeding direction of said piece of sheet metal.

    - Fig. 6 shows a section along line C-C in Fig. 5, - Fig. 7 shows a section along line A-A in Fig. 5, - Fig. 8 shows section B in Fig. 7 in an enlarged scale, - Fig. 9 is a side view of a stop element in the form of a finger, and - Fig. l0 is a broken sectional side view of a support frame supporting three stop elements of which one is in its folded position. lO Description of preferred embodiments In the below description and claims the term feeding direction shall be understood inconnection with the normal operation of the processing machine described and is intended toencompass both forward and rearward directions of the feeding direction if no other explanation is given.
    Fig. l shows the inventive support table l arranged at a processing machine 2 for sheetmaterial. ln a preferred embodiment the processing machine is a bending machine for sheetmetal. The support table l is preferably adjustably arranged at the processing machine 2 both in height and in the feeding direction of a piece of sheet metal 3 (shown in Fig 2).
    As can be inferred from Fig. 2, the support table l supports the piece of sheet metal 3 during aprocessing operation such as a bending operation. The support table l comprises at least onesupport frame l30, however preferably two support frames l30, such as two U-shapedsupport frames l30 or two support frame l30 having opposite sides l3l,l32 (see Fig. 4),wherein each of said support frame l30 supports at least one pivotably arranged main stopelement l0l. Said support frames l30 with the main stop elements l0l are movable back andforth in a feeding direction F of said piece of sheet metal 3 and by which said piece of sheetmetal is placed on said support table in a fixed relation to a processing line (not shown)defined by a processing station 4 (Fig. l) of said processing machine, i.e. so as to exactly line up/gauge the piece of sheet metal 3 in a fixed relation relative to said processing line.
    As can be seen in Figs. 6-8, for instance, each support frame l30 comprises a first adjustingdevice ll0 comprising two opposite acting adjustment screws ll0 for achieving a firstadjustment of the position of the support frame l30, and thereby the main stop element l0l,back and forth in the feeding direction F of said piece of sheet metal 3.
    With said first adjusting device ll0 a front stop element l0l° arranged at each support framel30 closest to the processing machine 2 is also adjustable back and forth in a feeding directionF of said piece of sheet metal 3. It should be noted that said front stop element l0l° ispivotably attached to the support frame l30 but not adjustable in the longitudinal direction of said support frame l30.
    Each main stop element 101 is further provided with a second adjustment device 120, seeFigs. 7 and 8, for achieving a second adjustment of the position of said stop element 101 backand forth in the feeding direction F of said piece of sheet metal 3 and in the longitudinal direction of said support frame 130.
    More particularly, as seen in Figs. 4 and 6-8, said main stop element 101 is supported withinthe U-shaped support frame 130. Each main stop element 101 comprises a finger 102 havinga front end 103 and a rear end 104, wherein the front end 103 is defined as the end directedtowards the processing station 4. A through oval hole 105 (Fig. 8) is formed in said finger 102transverse to the feeding direction F of said piece of sheet metal 3. A pivot pin 106 is arrangedto eXtend through said oval hole 105 and attached to opposite sides 131,l32 of the frame 130(Fig. 4). There is a play of between 0.5 to 2 mm, preferably between 0.8 to 1.7 mm, moreparticularly between 1.0 to 1.5, and especially about 1.2 mm, between an inner surface 107 ofthe through oval hole 105 and an extemal surface 108 of the pivot pin 106, as seen in thelongitudinal direction of the second adjustment device 120. Thus, finger 102 can pivot around the pivot pin and relative to the support frame 130.
    The plurality of fingers 102 are arranged in a plurality of parallel rows on the support table 1,and the fingers 102 in on row are pivoted by a cam device 140 connected to a rod 141 (Figs.3, 4, and 7) arranged to be rotated by a suitable device, such as a pneumatic cylinder 142. Therod 141 eXtends over a portion or over the whole width of the support table 1. Upon activationof the pneumatic cylinder the fingers 102 in one row are pivoted downwardly, i.e. areretracted into the U-shaped support framed 130 so as to form a plain upper surface of thesupport table, as seen to the left in Fig. 10.
    From Figs. 7 and 8 it can be inferred that the second adjustment device 120 comprises anadjustment means 121, one end 122,125 of which is arranged to rest against the pivot pin 106,and being adjustable connected to said finger 102 so as to enable movement of the finger 102relative to the pivot pin 106 back and forth in the feeding direction F of the piece of sheet metal 3.
    More particularly, in a preferred embodiment, the adjustment means 121 of said secondadjustment device 120 comprises a threaded screw 121, the threads of which is arranged to cooperate with corresponding threads formed in a hole 123 formed in the finger 102. ln a preferred embodiment a pin 124 is arranged in a threaded or unthreaded portion of said hole123 between the pivot pin 106 and a first end 125 of the threaded screw 121, so that a first end126 of the pin 124 rest against the pivot pin 106 and a second end 127 of the pin 124 restagainst said first end 125 of said threaded screw 121. The first end 126 of the pin 124 mayhave a shape complementary to the external shape of the pivot pin 106, which preferably has acylindrical shape. However, it should be noted the first end 125 of the threaded screw 121may rest directly against the pivot pin 106.
    As can be inferred from Fig. 8, in the upraised position of the finger 102, i.e. its normalposition, the hole 123 is formed at an angel to the longitudinal direction of the finger 102, anda front end 129 of said hole 123 starts at a recess 160 formed on an underside 111 of thefinger 102. The recess 160 has a surface 141, which is preferably perpendicular on one handto an upper surface 10 of the support table 1 and on the other hand to the longitudinaldirection of the threaded screw 121. This means that the threaded screw 121 eXtends in a direction parallel to the upper surface 10 of the support table 1.
    From Fig. 9 it can be inferred that the second adjustment device 120 further comprises aspring means 150, the function of which is on one hand to bias the rear end 104 of the finger102 via an adjustment screw 112 against a bottom surface 133 of the U-shaped support frame130 and on the other hand to bias the finger 102 against the pivot pin 106. One end 151 of thespring means 150 is arranged to be seated between a surface of the recess 160 and thethreaded screw 121 and the other end 152 is arranged to rest against the bottom of the U-shaped support frame 130. The spring means 150 is at a middle portion formed with springturns 113 which are threaded on and thus supported by the pivot pin 106.
    As can be seen from Fig. 7 and 10, in the upraised position of the finger 102, an angle formedbetween a surface of the front end 103 of each finger 102 and the upper surface 10 of thesupport table 1 should be about 90°. This angle is adjusted by the adjustment screw 112 (Fig.9).
    Furthermore, as seen in Fig. 1 and 2, the support table 1 comprises a base 11 (see Fig. 5)which supports the upper surface 10 and the U-shaped support frames 130. The upper surface10 is formed of a plurality of longitudinal profiles 12, 12' having two different widths. Said longitudinal profiles eXtend in the feeding direction F of the piece of the sheet metal 3.
    Between side edges of adjacent longitudinal profiles 12 at least one U-shaped support frame130 is arranged. More particular, a narrower longitudinal profile 12 together with an adjacentU-shaped support frame 130 have the same width as a wider longitudinal profile 12”.Moreover, said longitudinal profiles are arrangable on the base 11 (see Fig. 5) in anyconfiguration so that two or more longitudinal profiles, each having the same width, can bearranged adjacent each other. Preferably, each of the longitudinal profiles 12,12' is on its upper surface provided with at least one ball or brush transfer 14.
    As can be seen in Fig. 5, in the most forward row of the stop elements closes to the processingmachine, also a pivotable front stop element 101°, which is formed as a finger 102°, isattached to and enclosed by each support frame 130 and is arranged in front of the main stopelement 101 as seen in the feeding direction F. Said finger 102' is, in the same way as finger 102, pivotably arranged by the cam device 140 (Fig. 7).
    The adjustment in the feeding direction F of the fingers 102' is made in the same way as for the finger 102, i.e. by the two opposite acting adjustment screws 110.
