Definitions

the invention relates to a frame press according to the preamble of claim 1.
frame presses In known frame presses, the four workpiece parts or frame parts, which are pressed together to form a rectangular frame, are inserted into the press by hand after the pressure elements have been individually and manually set into their pressing position with the aid of scales or the like.
frame presses are known (DE-PS 29 24 257), in which the individual frame parts are pressed together to form a frame by means of power-driven press corners and fixed systems.
Such presses have a fixed longitudinal pressure beam or support and a movable longitudinal pressure beam or support with longitudinal and transverse counter-supports for the two frame parts arranged at right angles to one another and in the press. These frame parts are pressed by three press corners connected to the fixed or movable pressure beam.
the press corners are adjusted with the help of adjusting motors.
the setting of the press corners on the frame parts arranged at right angles to each other is achieved by sensing elements on the press corner assigned to the fixed pressure beam and on the lower press corner assigned to the movable pressure beam.
sensing elements on the press corner assigned to the fixed pressure beam and on the lower press corner assigned to the movable pressure beam For this purpose, it is necessary to provide, in addition to, ie outside the frame press, a receptacle arranged parallel to the fixed pressure beam and at the lower end of the press, into which corresponding work pieces are inserted before the pressing.
the discharge elements determine the presence of the frame part, the respective press corner is moved upwards and only stopped when the sensing element has moved beyond the frame part.
a fixed support with a press corner is assigned a stop rail which accommodates a vertical frame part and forms a vertical pressure beam and which is designed to be displaceable relative and parallel to the support;
the press corner has a sensing device which scans the upper edge of the frame part and which signals both the delivery of the press corner and the stop rail into the pressing position;
the lower press corner of the movable support is arranged to be movable from its working position for inserting the lower horizontal frame part into the press.
the upper left press corner is arranged on a fixed support and a movable stop rail for receiving the vertical workpiece part is movably attached to the base support and to the head rail.
a movable stop rail for receiving the vertical workpiece part is movably attached to the base support and to the head rail.
the object of the present invention is therefore to provide a frame press whose mechanical outlay is relatively low, which can be produced cheaply, and with which particularly simple work is possible, the frame parts being able to be inserted directly into the frame press and pressed immediately without that a separate measuring process on the frame parts outside the machine is necessary and without corresponding measuring workpieces or the frame parts having to be inserted or positioned twice.
the fixed support here receives a press corner which can be moved in the horizontal direction, for example via a rack and pinion gear with a pressure medium drive, a direct-acting pressure medium drive or the like
Variant of both the fixed vertical support and the lower horizontal support is assigned a tensioning strap against which the relevant frame part rests when it is inserted and during pressing.
the upper press corner is omitted. Since the fixed stop of the vertical support accommodates the vertical frame part, a vertical tensioning strap or the like is not necessary. Also in this variant the left upper press corner is omitted, since the pressure piston with the pressure plate is arranged on the movable bar, and the movable bar is moved directly to the corner connection between the vertical and horizontal frame part and the pressure cylinder is extended downwards at the press point. The pressure cylinder is firmly connected to the movable bar.
a press according to the present invention an extraordinarily simple and effective possibility is created for a frame press in which the frame parts which are inserted directly into the frame press can be pressed immediately with no further handling, with a minimum of effort.
the use of clamping straps eliminates the need for support beams for the individual workpieces that are pressed into the wooden frame.
a vertical, movable support for the movable press corner has been avoided in that the press corner is fastened to the fixed vertical support so that it can move horizontally. Since this upper left press corner is open, the press corner cannot hinder the insertion of the vertical frame part and cannot cover the sensor which detects or scans the inserted frame part.
the control of the press corner is designed so that after the pressing process, the press corner is moved into an upper and right standby position seen from the working position, so that a new vertical frame part for the new pressing process can be inserted while at the same time moving the lower right press corner or the pressure cylinder acting upwards in the vertical direction with the pressure plate upwards, so that the required space for inserting the lower horizontal frame part is created.
the printing cylinder in question can also be designed to be pivotable in order to achieve the free space for inserting the relevant frame part.
Such a swivel arrangement is to be regarded as equivalent in comparison to a back and forth movement of the respective printing cylinder and is within the scope of the skill of the average person skilled in the art.
Fig. 1 the frame press is shown schematically in an overall view.
Side stands 2, 3 are rigidly fastened with a stationary base support 1 and are connected to a rectangular frame via a head rail 4.
the movable support for the right press corners 6 and 7 is designated, with 8 the fixed support which receives the left press corner 9.
the press corner 9 is connected to the fixed support 8 via a rail-shaped bracket 10 on which the Press corner 9 is arranged to be movable horizontally in the direction of the arrow shown.
the pressure cylinder 11, which extends in the vertical direction, is fastened to the pressure corner 9 with the pressure plate 12; a double cylinder arrangement can also be provided here.
the frame parts 13, 14, 15, 16 to be pressed into a rectangular frame are inserted into the frame press for pressing.
the frame part 16 lies against a vertical tension band 17 which is fastened to the fixed support 8.
the lower end 18 of the strap 17 is rigidly connected to the fixed support 8, while the opposite end 19 is held so tight that the strap 17 does not spring during operation.
a horizontal strap 20 is provided for receiving the lower horizontal frame part 15.
the tensioning strap 20 is rigidly attached to the horizontal base support 1 at one end 21, while the opposite end 22 of the tensioning strap 20 is kept tight, also to prevent springing.
the frame parts 15 and 16 are fixed by hydraulic holding members 23, 24 when they are placed against the tensioning straps 20 and 17 in order to position the frame parts before the pressing.
the press corner 9 is moved to the right and up into a standby position, after inserting the remaining frame parts, the press corner 9 is moved to the upper left corner of the wooden frame 13-16 and the pressure plate 12 to initiate the pressing process Pressing extended together with the pressure cylinder 11.
an optical sensor 25 is provided which scans the frame part 16 and which controls the delivery of the press corner 9.
a fixed stop plate 26 is also provided against which the steel strip 17 and the wooden frame lie during pressing, this stop plate being designed as an abutment for the pressing process.
the press corner 9 is open in the region of the extension of the frame part 16, so that the press corner does not hinder the insertion of this frame part into the frame press before the start of the pressing process.
the press corner 6 is designed in the manner customary for automatic frame presses.
the lower right press corner 7 is controlled in such a way that the pressure cylinder acting upwards is automatically moved upwards when the press corner 9 or the pressure cylinder 11 is moved laterally, so that the space required for inserting the frame part 15 is created.
the steel strips 17 and 20 preferably have guide stops 27 arranged at a distance from one another, which facilitate correct positioning of the frame parts 16 and 17. Furthermore, in accordance with the stop plate 26, which is assigned to the tensioning strap 17, a corresponding stop plate 28 or the like is also assigned to the horizontal tensioning strap 20.
the fixed support is designed in the form of a vertical fixed stop, which has an angular strip 30, so that the frame part 16 can be securely received and positioned.
a vertical strap (analogous to strap 17) is not required.
the movable bar 31 is mounted horizontally displaceably on a support 32 rigidly connected to the fixed stop 29.
the movable carrier 31 receives a pressure cylinder 33, which acts in the vertical direction, and this pressure cylinder is displaceable together with the movable carrier, so that the carrier and the pressure cylinder are adjusted to the pressing point.
the pressure cylinder is thus moved with the bar, while in the variant according to FIG. 1 the press corner 9 is designed to be displaceable relative to the fixed support.
