Definitions
- the present invention relates to a machine intended for the formation of sheet metal panels and, more particularly, to carry out the necessary folds to the application plates using means which effectively make the work of this function.
- machines that realize automatically bending sheets, at angles predetermined, said machines comprising a punch and a matrix, between which the forming of sheets by folding, this operation being carried out by progressive folding, to compensate for the capacity of recovery of folded sheets which varies depending on various factors, such as the nature of the material, the size, etc.
- Folding precision also requires exact control of the angle obtained and, for this purpose, uses measurement systems associated with the folding, consisting of a laser measuring instrument, in complex devices integrated into the folding punch or in independent portable devices, the systems in question proving complicated and expensive.
- the subject of the present invention is a machine which includes means for folding and a device for measuring the angle of the folded sheet, different in their design of known systems and offering certain advantages for the practical function of the folding of the application sheets.
- the machine which is the subject of the present invention includes a folding mechanism consisting of a blade holder mobile located in front of a holding device and immobilization of the sheets to be folded, the device immobilizer comprising a fixed lower part or counter blade and an actuated upper sheet clamp vertically using a push cylinder, while the blade holder is fitted with a probe arranged on a cylinder displacement which leads it towards the device sheet immobilization.
- the blade holder is incorporated in a device for translation which ensures its movement towards the device sheet immobilization and an articulated device tilting which allows to vertically vary its position relative to the immobilizer sheets, the two movements being provided by the two drive cylinders.
- the sheet clamps of the device for immobilizing sheets is arranged on a carriage driven by the cylinder pusher, the blank holder in question consisting of a assembly formed by two end blocks and a block central which determine a continuous longitudinal shape, the central block can be replaced to modulate the longitudinal dimension of the assembly as a function of the width of the application sheets.
- the blade holder includes a cart capable of automatically transport the central block of the blank holder from the mounting position to a magazine containing several blocks of different lengths, to allow selective replacement of the block in question in the longitudinal adaptation of the blank holder, the carriage replacement being driven by an independent cylinder or associated with that of the probe also incorporated in the blade holder.
- a functional group is thus obtained which makes it possible to quickly and precisely bend sheets at predetermined angles, controlling with automatic measurement of the folding angle for determine the corrections necessary for the operation.
- the functional assembly can be adapted to sheets of different widths, thanks to the change automatic selection of the length of the blank holder of immobilization, which makes it possible to obtain a large speed in the operational operating arrangement compared to the application sheets.
- the machine subject to present invention actually has features very advantageous, by acquiring a clean life and a reference character for the function to which it is intended.
- Figure 1 shows a sectioned side view of the panel maker recommended.
- FIG. 2 is a sectioned view of the machine, in upper shot.
- Figures 3A to 3E show a sequence of successive positions of the bending operation of a sheet and control of the folding angle.
- the subject of the invention is a paneling machine intended for automatically bend sheets (1), according to the folds necessary for the formation of door panels, partitions or similar applications.
- the machine has a folding mechanism which comprises a blade holder (2) arranged, in mobile mounting, facing a sheet immobilization device (1) at to fold.
- the immobilizer comprises a part lower (3) or counter blade fixed on the structural frame (4) of the machine and an upper hold-down (5) likely to be driven vertically against the lower part (3) mentioned above in order to immobilize between one and the other part the application sheets (1) to be able to perform the folding operations.
- the blade holder (2) is arranged in articulation of vertical tilting on carrier trolleys (6) mounted on slides that lead them to the device sheet immobilization (1).
- the carriages (6) are joined to the respective cylinders (7) which allow them to move forward and backward while the blade holder (2) is joined to one or more cylinders (8) which ensure the vertical tilting of the blade holder (2) in relation to the articulation provided on the carriages carriers (6).
- the blade holder (2) is equipped with a probe (9) arranged on a jack (10) which leads it to the part front where the immobilizer of the sheets (1).
- the sheet (1) to be folded is retained using the immobilization device between the blank holder (5) and the fixed part (3), as illustrated in FIG. 3A, of so that when the sheet ends up in this position, the movement of the blade holder (2) driven by the jacks (7 and 8) cause the end of the the sheet (1) immobilized, as shown in the figure 3B.
- the blade holder is automatically driven by the cylinders (7 and 8) depending on the programmed folding angle in the control of the machine, the bending of the sheet performed during a first operation according to the angle programmed, without exceeding this angle, after which the blade holder (2) returns to the starting position, as as illustrated in Figure 3C.
- the cylinder (10) then drives the probe (9) and the leads to the bending zone of the sheet (1), as as illustrated in Figure 3D; then, by tilting blade holder (2) required, the probe (9) is set to contact of the extreme zone of the folded part of the sheet (1), as shown in Figure 3E.
- the blank holder (5) is arranged on a carriage (11) articulated on the structural frame (4) of the machine, the carriage (11) in question being driven in tilting by the jack (12), this same jack exerts pressure against the sheets (1) to immobilize them by bringing the blank holder (5) against the fixed lower part (3).
- the blank holder (5) consists of two blocks end and a central block which determine the length of the body of the blank holder (5), the central block can be replaced by blocks of different lengths, which allows you to adjust the length of the whole blank holder (5) depending on the width application sheets (1) so that the operation of the machine is as precise as possible in each case.
- the blade holder (2) is equipped with a carriage (13) which automatically replaces the central block of the blank holder (5) depending on the width sheets (1) to be folded with the machine in each case, so that the carriage (13) moves and grips pass the central block of the blank holder (5) for the lead to a store (not shown) containing several similar blocks, of different lengths, where the carriage (13) in question takes the appropriate length block, then take it to the blank holder (5) and place it in the center of it.
- the carriage (13) is driven by a jack (14) controlled by the machine control, said cylinder (14) can be an independent cylinder, used only for move the carriage (13); but we also planned the possibility of using the jack (10) for this function of the probe (9), in which case the carriage (13) would be associated said cylinder (10) relative to the corresponding control to perform this central block change function blank holder (5).
