Definitions
- the invention relates to a press for pressing plate-shaped workpieces with at least two pressure chambers the closer in the preamble of claim 1 marked art.
- each pressure chamber it is necessary for each pressure chamber to have one separate lifting table, i.e. separate pressure bar and associated lifting cylinder, i.e. Pressure cylinder with piston, be assigned.
- the invention is therefore based on the object of a press of the generic type in which two create each other neighboring pressure rooms alternately opened and can be closed.
- Lifting table has a double function in relation to the two press rooms to, because in the first cycle he presses the material to be pressed a pressure chamber against the first fixed press table, the remote pressure room is open, and in the second Working cycle is the material to be pressed in the second pressure chamber against the second fixed press table pressed while the first Print room is open.
- the lifting cylinder immediately above or below the Lift table adjacent fixed press table what shortens the path of the adhesion.
- the lift table can too from both upwards and downwards Lift cylinders are driven, which varies depending on the type of pressure forces to be applied. Since the pressure rooms of the lifting cylinders must not be impaired it conveniently on the side outside of the lifting table and the concerned press table.
- the press according to the invention is in the form of a modular system expandable. So can be above the upper press table or a third pressure chamber below the lower press table located from an above or below, driven via lifting cylinders mounted on the frame second lifting table is limited.
- Such a press with three pressure rooms or one with two neighboring pressure rooms, always two these pressure rooms open and close alternately, can be combined with each other and on top of each other being constructed. So each can be made up of two fixed ones Press tables with two by one arranged in between A first press room separate from each other Form press unit. A second press unit is obtained by having two of these fixed press tables with in between arranged two separated by a lifting table Press rooms around one arranged above or below third pressure chamber supplemented with a second lifting table.
- the on press units formed in this way can be any can be combined with each other, with the sides of the fixed press tables adjacent press units one each have only one press table in common at their interface can.
- the press according to the invention can, as far as the individual Pressure rooms, also as a so-called multi-daylight press be carried out at the relevant pressure rooms by means of intermediate plates in two or more floors are divided. These intermediate plates can be used as required be designed as heatable plates.
- FIG. 1 shows a machine frame 1, which has vertical columns, which over suitable Connection means 12 with an upper fixed press table 2 and a lower fixed press table 3 are connected. Between two fixed press tables 2 and 3 are in Height direction adjustable lift table 4, the top a first pressure chamber 5 and a second downwards Pressure chamber 6 limited. Since the distance between the fixed press tables 2 and 3 is constant, changes when the lifting table 4 moves between the two fixed press tables 2 and 3 the height of the Pressure rooms 5 and 6 depending on each other, so that how in the embodiment of Figure 1 in the pressing process in second, lower press room 6, the upper press room 5 is open.
- the material to be arranged in the press rooms 5 and 6 is in the Drawing not shown in detail, you can see in the Print rooms 5 and 6 only intermediate plates 8, which the Subdivide pressure rooms 5 and 6 into several floors.
- the lifting table 4 is driven by double-acting Lift cylinders 7, the side outside on the lifting table 4 and on upper press table 2 are articulated. Basically you can further such drive units also between the lifting table 4 and the lower fixed press table 3, if provided on the upper lifting cylinder 7 alone the necessary pressure can be applied.
- the press unit described above with the two pressure rooms 5 and 6 and the upper fixed press table 2, the lower fixed press table 3 and the lifting table 4 represents a basic element for a kit that either doubles or can be multiplied or even by one more Pressure room can be supplemented with a lifting table.
- the latter embodiment shows Fig.1, where under the lower fixed press table 3 another via lifting cylinder 11 powered lift table 9 is located between itself and the arranged above the lower press table 3 of the upper Press unit includes a second pressure chamber 10 which also divided with intermediate plates 8 into several floors can be.
- This arrangement can also be a press unit form, for example upwards by one Press unit with an upper fixed and a lower one fixed press table and a lifting table movable between them 4 can supplement.
- Fig.2 shows a press made up of two stacked Press units such as those described above as the basic element have been designated. You can here at the Interface between the two press units provide common fixed press table 2.3, one of the two press units as a so-called add-on unit is designed in which you save a fixed press table.
