Preferably, the guider of conversion work platform can be withdrawn into below the surface of conversion work platform.Like this, the conversion work platform can be retained on its position, and sheet metal can be by from first thruster to second side when guide roller is withdrawn, and guide roller is reset sheet metal is led after this.Another selection, guide roller are not collapsible, but conversion work platform and the sheet metal on it are done as a wholely to move by side to second side from first of roll forming machine.
The present invention will describe by accompanying drawing an embodiment who gives an example.
Fig. 1 represents the diagrammatic top view according to equipment of the present invention, and the tapered sheet of this equipment and different production phases together.
The side view of the equipment of Fig. 2 presentation graphs 1.
Fig. 1 represents the vertical view according to roll forming machine 1 of the present invention, has to enter workbench 10 and conversion work platform 20.As shown in the figure, flanged wedge metal thin plate is at 4 place I, II, III, the IV of its manufacture process.Fig. 2 represents the side view of roll forming machine 1 and workbench 10,20.
Roll forming machine 1 has first bolster 2 and second bolster 3, first side 7 and second side 8 by framework 4 supportings of band front end 5 and rear end 6.Bolster is paired, and for example 2a, 2b install, as shown in Figure 2.The forming rolls (not shown) is installed on bolster 2,3.The different first right forming rolls are installed at each on to first bolster 2.Make the first side of sheet metal form flange from the forming rolls of the front end 5 of the roll forming machine 1 a pair of arrangement of 6 one butt joints from flat state to the rear end.Similarly, the different second right forming rolls are installed on to second bolster 3, should were made the second side of thin plate from flat state formation flange by 6 the second different right forming rolls from the rear end to a pair of arrangement of front end 5 one butt joints at each.
Enter supporting arrangement that workbench 10 is placed on front end 5 places of roll forming machine 1 and has a sheet metal such as the backing roll (not shown), be aligned to the guide roller 11 that straight line is placed with framework 4, so sheet metal is aligned to straight line and enters roll forming machine 1 with its first side and forming rolls with roll forming machine 1.Three pressing devices are installed in entering workbench, and the pushing roller 12 of this pressing device is illustrated.These pushing rolls for example are connected on the pneumatic cylinder, and this pneumatic cylinder continues the pushing sheet metal leans against on the guide roller it, even when the wide variety of thin plate, as the situation of tapered sheet also is.
After considering that suitable details changes, this is equally applicable to have the conversion work platform 20 of guide roller 21 and pushing roller 22.But the conversion work platform also must allow sheet metal moving from the side direction of first side, 7 to second sides 8 of roll forming machine 1.For this reason, might move and make as a whole conversion work platform 20.The another kind of selection be, might work as the conversion work platform, to remain on its position when motionless sheet metal mobile on conversion work platform 20.In order to do like this, guide roller 21 must be able to be retracted to the bottom on workbench surface, so that unlikely obstruction thin plate moving from first side, 7 to second sides 8 of roll forming machine.
The shaping of the sheet metal of second relative flange will illustrate as after.
In Fig. 1, the wedge metal thin plate is expressed and is in its shaping place I, is still flat at this place thin plate.Thin plate is placed on to enter on the workbench 10 and by pushing roller 12 its first side is pushed against on the guide roller 11.
Sheet metal moves into roll forming machine 1 and passes through the roll forming machine along direction B along direction A then.In thin plate was entering moving process on the workbench 10, pushing roller 12 was along direction P mobile guide roller 11, because the width of tapered sheet diminishes towards the end of thin plate.
When thin plate was moved through roll forming machine 1, first forming rolls on first side 7 of roll forming machine 1 formed first flange continuously on sheet metal.
After thin plate had left first side of roll forming machine 1, sheet metal was in its place II, had first flange at this place thin plate in its first side.
Sheet metal to a side shifting, is in second side 8 places of roll forming machine 1 up to it at conversion work platform 20 upper edge direction C then.Thin plate is pushed against on the guide roller 21 by pushing roller 22 there.This is the place III of sheet metal.
Thereafter, sheet metal moves into roll forming machine 1 and passes through the roll forming machine along direction E along direction D.In the moving process of thin plate on conversion work platform 20, pushing roller 22 21 is removed along direction P from guide roller, because the width of tapered sheet increases towards the end of thin plate in this moving process.
When thin plate moved through roll forming machine 1, second forming rolls on roll forming machine 1 second side 8 formed second flange continuously on sheet metal.
When thin plate left roll forming machine 1, it had arrived it and the 4th has been last place IV and can be taken off along direction F.
Though not expression will be very clear, roll forming machine according to the present invention have mobile device such as mobile roller in case the moving metal thin plate by the roll forming machine and it is moved on workbench.
To have different flange heights be sheet metal in order to form, and for example the upper support axle is adjustable in vertical direction, so that can use the forming rolls with different-diameter.Use a central tooth roller box to make all bolsters by synchronously.
Will be appreciated that though the roll forming machine is designed to form flange on the wedge metal thin plate, the roll forming machine can be used for forming flange equally on straight, rectangular metal thin plate.Also with clear, though the shaping among Fig. 1 is the broadside that is expressed as from tapered sheet, also may be from narrow limit.
In addition, will be appreciated that, can under the situation of the design that does not change the roll former, the design of breaker roll forming machine make amendment.For example may be that the roll forming machine makes wide framework, and therefore make the end of bolster be installed in a left side and the right side of framework.Like this, the roll former looks and looks like traditional roll forming machine that is used for straight thin plate, thin plate must move between roll forming machine two sides in traditional roll forming machine, but the now forming roll is differently installed, and sheet metal at first returns against the opposite side of roll forming machine then against a side shifting of roll forming machine now simultaneously.
