Definitions
- the invention relates to an articulated lever, cutting and forming press according to the preamble of claim 1.
- the stroke of the fixed drive cylinder fixed to the frame is determined in a known manner by the transmission ratio resulting from the toggle lever drive and the type of handlebar.
- C-frames are generally ruled out for presses according to the definition given at the beginning, since their frame springing greatly influences the cutting accuracy in the case of presses with a high load capacity.
- the press stand is a two-stand frame which is also partially closed on the front and end sides, that the working area of the ram in the stand is driven by synchronously drivable spindles, which are carried by threaded guides formed in the upper crossbeam of the stand, and further ends in the spindle bearings formed on the height-adjustable guide crossbeams provided on both sides, is adjustable, and that the guide crossbeams are provided on their underside with bearings for the hanging arrangement of the articulated lever pairs connecting the plunger.
- the setting of the working area of the ram is carried out by the spindles carried by the stand, which are usually driven synchronously by an electric motor, and which end in bearings formed on the guide cross members.
- the second row of bearings located on the underside of the guide crossbeams serves to connect them to the tappet via the pairs of articulated levers.
- the height-adjustable guide crossmembers with a slide plate, which is arranged in a guide bed formed on a support and support wall closing the back of the stand, and with a Gleri plate, which is arranged in a front of the stand
- the support and support walls are rigid - fixed or detachable - connected to the stand
- on the lateral boundaries of the plunger guides for corresponding engagement in the with the support and Retaining wall releasably but rigidly connected side guides are provided and these side guides further have an additional position securing against the upright columns by means of wedge connections.
- the partial front and rear closure of the press stand enables the formation of a vertically running guide bed in the supporting and supporting walls for the arrangement of the sliding plates rigidly assigned to the guide cross members and allows one With the setting of the working area, the essential guide means for the ram are also adjusted over the working area.
- the side guides are independent and, as mentioned, arranged on the stand and secured in position.
- the articulated lever design and the drive of the tappet further provides that the upper articulated levers arranged on the articulated bearings are connected in the joints to the lower articulated levers, which in turn are attached to the lower articulated bearings attached to the bottom of the tappet - to those formed on the guide cross members below Bearings directed - are connected, the articulated levers being connected in a known manner via the handlebars to the multi-joint carrier guided in the press and, to a large extent, via the piston rod to the pressure medium cylinder drive connected to the tappet.
- the press-center guided multi-joint bracket which is connected on the one hand to the pressure medium cylinder drive connected to the tappet and on the other hand via the handlebars to the articulated lever system, is guided in the press center independently of the tappet, namely in the sliding plates already mentioned, so that an absolutely exact adjustment of the working area independent articulated lever drive and thus safe ram drive is guaranteed.
- the handlebars of both articulated lever systems on the central multi-articulated support end in one or in a multi-part coaxially oriented one, or in two parallel one-jointed or multi-part jointed axes, the control arms in two parallel Articulated pins can be crossed occasionally.
- the most expedient design for the rule of thumb is a two-way parallel arrangement of the links on the pivot pins or shafts which are mounted in the multi-joint support.
- the upper articulated levers arranged on the guide crossbars can be combined with "n" handlebars and with "n - 1" lower articulated levers.
- the upper articulated levers are fork-shaped at their ends directed to the articulated connection with the handlebars.
- the distance between the upper limit of the press table and the lower limit of the rear support and support wall has a dimension slightly exceeding the sum of the height of the tool and the stroke.
- the design of a press with two rams provides that in a double stand designed in the form of a high stand, two rams working in opposite directions in the box position are arranged, with the vertical ram of the bottom working ram, with otherwise the same design as the upper ram a small dimension that takes into account the required passage through the press table is extended.
- the upper and lower pressure medium cylinder drives for the tappets are connected to one another hydromechanically via a control control element, digitally programmable and monitoring ultrasound displacement sensors being assignable to the control control element.
- the double stand In order to keep the press table in a normal working position, the double stand is provided with riot claws on both sides for its partial underfloor arrangement.
- the press stand 1.1 is closed at the bottom by a base plate 1.2, whereby on the two lateral edge boundaries of the base plate 1.2 and then directed inwards, build the stand columns 1.3 and the stand 1.1 is self-contained by the connecting upper cross member 1.4 designed as a box girder .
- the table substructure 1.5 is formed in the foot area, which is delimited at the top by the press table top 1.6 lying thereon.
- the pillars 1.3 are connected in their upper area - and flush with their height - by the rear support and support wall 1.7.
- a vertically running guide bed 1.7.1 for receiving the rear sliding plate 2.5 is formed on this plate.
- the support and support wall 1.7 is dimensioned relatively strong, ribbed backwards, and engages between the stand columns 1.3, directed downwards, somewhat above the height of the setting and working range of the ram 2.1.
- the plunger 2.1 is also delimited at the front by a further supporting and support wall 1.8, which is detachably arranged at a distance from the upper stand boundary and is lower in height, which in turn is provided with an embedded guide bed 1.8.1 for the end-side sliding plate 2.6.
- the rear support and support wall 1.7, the side guides 1.9 arranged on both sides of the plunger 2.1 are screwed and pinned and additionally secured in position with the stands 1.3 by wedges 1.10.
- the thread guides 1.11 for the spindles 2.2 are configured for the basic setting of the tappet 2.1, the threaded spindles generally being able to be driven synchronously by a motor.
- the spindles 2.2 engage on both sides in a support bearing 2.3 formed on a height-adjustable guide cross member 2.4, while the bearings 2.3.1 are provided on the underside of the guide cross members on the two sides for the suspension of the articulated lever systems are.
- the guide crossbeams 2.4 are connected to the slide plates 2.5 and 2.6 which can be inserted in the guide bed 1.7.1 and 1.8.1, this connection generally being a screw or pin connection.
- the pressure medium cylinder drive 2.12 consisting of piston 2.13 and piston rod 2.14 engages with the piston rod 2.14 in the central multi-joint carrier 2.8, on which the links 2.8 are connected by pivot pins 2.17.
- rows of spherical bearings 2.9 are provided which accommodate the articulated lever systems arranged on the guide cross members 2.4 or on the bearings 2.3.1 connected to them.
- the articulated lever system consists of the upper articulated levers 2.10 assigned to the guide cross members 2.4 and the lower articulated levers 2.9 articulated articulated levers 2.11.
- the articulated lever systems bend inwards, i.e. towards each other.
- a support frame for receiving a pressure medium container can be provided on the rear front of the stand 1.1, i.e. on the rear support and support wall 1.7.
- the distance between the lower limit of the rear support and support wall 1.7 and the upper limit of the press table 1.6 should only correspond to the tool height plus the stroke of the ram 2.1, i.e. So, be as small as possible in order to minimize the spring deflection of the stand 1.1 in connection with the formation of the tappet and the arrangement of the articulated levers in the tappet 2.1, the all-round guidance of the tappet 2.1 consisting of the adjustable side guides 1.9 arranged on both sides , the slide plate 2.5 guided in the support and support wall 1.7 and the slide plate 2.6 guided in the front support and support plate 1.8 in conjunction with the guidance of the central multi-joint support 2.7 driven by the piston rod 2.14 also taken over by the two slide plates 2.5 and 2.6 Zero leading dimension of the frame suspension is reached.
- the pressure medium cylinder drives 2.12 are opposite, i.e. arranged above and below in the plunger 2.1, the further plunger design for the top and bottom corresponding to FIGS. 1 to 3 and the statements made thereon.
- the lower press stroke 2.1 is extended in order to be able to take into account the thickness of the press table 3.2 when the ram 2.1 passes through to the TDC position.
- the double frame 3.1 is fixed in a machine pit on riot claws 3.3, so that there is a normal table height.
- a control controller 3.4 is provided for the hydromechanical connection of the upper and lower pressure medium cylinder drives.
