Abstract
Description
- The invention relates to an apparatus for bending a metal sheet as defined in the preamble of
claim 1 . Such an apparatus is known from US-A-4.612.796. - When using such an apparatus for bending a metal sheet, often a number of different dies are used. Therefore, for an economic use of the apparatus, it is essential that dies can be exchanged in a rapid manner.
- It is an object of the invention to provide an improved apparatus of the type referred to above allowing a swift exchange of dies. This object is achieved by an apparatus according to
claim 1. - Therefore, the apparatus according to the invention is characterized in that the respective beam comprises a ridge extending longitudinally alongside the channel, wherein the pressure piece is shaped as an inverted channel beam positioned over the ridge in such a manner that one leg thereof is positioned at one side of the ridge and defines the said one side wall of the channel, the web surpasses the ridge, and the other leg is positioned at the opposite side of the ridge, and wherein the bias means are positioned between the ridge and one of the legs, whereas the fluid-inflatable means are positioned between the ridge and the other of the legs.
- According to the invention the ridge, which is a stationary part of the respective beam, acts as a support for the bias means as well as the fluid-inflatable means.
- In a preferred embodiment, the bias means may be positioned at the side of the ridge facing the channel. Then the bias means bias the pressure piece in a direction for clamping the die in the channel. For exchanging the die it then is necessary to inflate the fluid-inflatable means. In such an embodiment the apparatus in its inoperative position (fluid-inflatable means not inflated) securely holds the die in the respective bending beam.
- However, also the opposite is possible. In such an opposite case, the bias means are positioned at the side facing away from the channel, whereas the fluid-inflatable means are positioned at the side of the ridge facing the channel. In this embodiment the die is not clamped when the fluid-inflatable means is inactive (not inflated), and securely holding the die is only realised when the fluid-inflatable means is inflated.
- When the bias means are housed in recesses provided in the ridge, the dimensions of the inverted channel beam, and thus the respective bending beam, can be limited.
- In a further embodiment of the apparatus according to the invention the pressure piece and the respective beam are provided with co-operating abutment means for limiting the relative movement therebetween. Such co-operating abutment means can prevent a damaging of the pressure piece due to a too large a movement thereof at longitudinal positions along the bending beam where no die is provided.
- For preventing an unwanted movement (tilting) of the respective die, it further is preferred that the respective beam and the pressure piece have top surfaces extending in the same plane. Shoulders of the die extending in the same plane will engage these top surfaces for a correct positioning of the die relative to the bending beam.
- Sometimes the die to be received in the channel has a reduced length. In such a case it may be of advantage when the pressure piece at its side facing the channel is provided with flexible members, such as for example flexible strips or alike, for engaging the die.
- Finally, in another embodiment of the apparatus according to the invention, the pressure means is secured to the respective beam by means of securing means allowing only the movement of the pressure means normally to the channel. These securing means prevent the loss of the pressure means, for example during the exchange of dies.
- Hereinafter the invention will be elucidated referring to the drawings, in which an embodiment of the apparatus according to the invention is illustrated.
- Fig. 1 shows, in a perspective view, part of an embodiment of the apparatus according to the invention;
- Fig. 2 shows, on a larger scale, a perspective view of the lower part of the apparatus of Fig. 1;
- Fig. 3 shows a first sectional view of the embodiment illustrated in Fig. 2;
- Fig. 4 shows a second sectional view of the embodiment illustrated in Fig. 2, and
- Fig. 5 shows a sectional view of an alternative embodiment of the apparatus according to the invention.
-
- In Fig. 1 an apparatus for bending a metal sheet is partly illustrated. This apparatus comprises an
upper bending beam 1 supporting anupper die 2 and alower bending beam 3 supporting a complementarylower die 4. Thebending beams upper die 2 and lower die 4, whereupon theupper bending beam 1 andlower bending beam 3 are moved towards each other. After the bending operation has been completed, the upper andlower bending beams - The
upper die 2, in the illustrated embodiment, is attached to theupper bending beam 1 byconventional means 5 which will not be explained in detail here. It should be noted, however, that the following could also apply for theupper die 2. - The
lower bending beam 3 is provided with a longitudinally extendingchannel 6 in which thelower die 4 is detachably housed. The manner in which thelower die 4 is detachably housed in the longitudinally extendingchannel 6 formed in the respectivelower bending beam 3 will be explained referring to the following drawings. - Fig. 2 shows, in a perspective view and on a larger scale, part of the
lower bending beam 3 with longitudinally extendingchannel 6 formed therein. The lower die 4 is housed in thechannel 6. Alongside the channel 6 aridge 7 extends longitudinally. Apressure piece 8 shaped as an inverted channel beam is positioned over theridge 7 in such a manner, that oneleg 9 thereof is positioned at the side of theridge 7 facing thechannel 6, theweb 10 thereof surpasses theridge 7, and theother leg 11 thereof is positioned at the side of theridge 7 facing away from thechannel 6. - In the assembled position as illustrated in Fig. 2 the
top surface 12 of thelower bending beam 3 and thetop surface 13 of thepressure piece 8 extend in the same plane. Thesetop surfaces shoulders 14 of thelower die 4, in such a manner that thelower die 4 is in a stable manner positioned in the lower bending beam 3 (e.g. preventing tilting thereof when loaded). - Referring to Fig. 3, securing means shaped as a
pin 15 are attached inmounting holes 16 in theridge 7. These securing means 15 extend through openings in theweb 10 of thepressure piece 8, wherein the dimensions of the openings are larger than the dimensions of thepin 15. In such a manner, thepressure piece 8 can move perpendicularly (normally) to thechannel 6, but not in another direction. - The
ridge 7 further is provided with transversely extendingrecesses 17. As shown in Fig. 2 and 4, theserecesses 17 are at the right-handed side closed bycovers 18. In each recess 17 a flexible means, in this embodiment arubber block 19, is housed. Thisrubber block 19 engages and biasesleg 9 of thepressure piece 8. - Between the
ridge 7 and the other leg 11 (see Fig. 2 and 3) a fluid-inflatable means 20 is positioned. In the illustrated embodiment, this fluid-inflatable means may comprise a flexible compressed air hose. - The apparatus according to the invention operates as follows. In a non-operative position (Fig. 3) the fluid-inflatable means 20 is not inflated. The
rubber blocks 19 are biased and engageleg 9 of thepressure piece 8, moving it towards thechannel 6 and thus towards the die 4 housed in thechannel 6. Thus, when the fluid-inflatable means 20 is not inflated, the bias of therubber blocks 19 securely holds thelower die 4 in thelower bending beam 3. - The movement of the
pressure piece 8 under influence of the bias of therubber blocks 19 is limited by co-operating abutment means 21 and 22 of thepressure piece 8 andlower beam 3, respectively (see Fig. 4). Thus it can be prevented, that (at longitudinal positions where nolower die 4 is housed in the channel 6) thepressure piece 8 would be deformed and be damaged. - When the
lower die 4 has to be exchanged and thus should be removed from the channel 6 (or, alternatively, only should be moved longitudinally in the channel 6), the fluid-inflatable means 20 is inflated. When this means 20 expands, it engages theleg 11 of thepressure piece 8 and thus thepressure piece 8 is moved to the right opposing the bias of therubber blocks 19. This position is shown in Fig. 4. This movement is limited by a contact between the opposing faces of theleg 9 of thepressure piece 8 andridge 7. - In the position illustrated in Fig. 4 the
lower die 4 is no longer engaged by thepressure piece 8 and can be removed (or moved). - At its side facing the
channel 6 thepressure piece 8 is provided with flexible members 23 (indicated in Fig. 3), such as for example flexible strips or alike, for securely engaging thelower die 4. - Fig. 5 shows an alternative embodiment, in which the rubber blocks 19 and fluid-inflatable means 20 have changed positions. In this embodiment, the
lower die 4 is held securely in thelower beam 3 when the fluid-inflatable means 20 is inflated. Deflating the fluid-inflatable means 20 leads to disengaging thelower die 4. - The invention is not limited to the embodiments illustrated here, but can be varied widely within the scope of the invention as defined by the claims. The fluid-inflatable means do not necessarily have to be inflated by compressed air. Instead of rubber blocks the bias means also may be shaped as any type of spring members.
- Whereas in the illustrated embodiment only one side wall of the
channel 6 is movable and the other side wall is stationary, one should realise that also both side walls can be movable, and in such a case two pressure pieces are provided. - Further it should be noted, that the apparatus as illustrated in Fig. 1 also could be provided with an
upper die 2 which is housed in theupper beam 1 in a corresponding manner as thelower die 4 in thelower bending beam 3.
