Definitions
- the invention relates to a toggle clamping device with a cylinder, a piston, a sealing element, a piston rod, a toggle joint assembly, a clamping head and a clamping arm, wherein in the cylinder, the piston is sealed by the sealing element liftable movable by compressed air, wherein the piston via the piston rod and the toggle link assembly, which is located in the chuck, moves the clamp arm, and the cylinder has a cylinder bottom and a cylinder cover, with a further channel disposed therein, through which engages the piston rod in the chuck.
- Toggle jigs of the presumed kind are used in large numbers in the bodywork of the automotive industry. There, they usually serve to hold together sheet-metal components that are joined together by clinching (local high compression), gluing or spot welding.
- toggle clamping devices of this type usually drives a piston via a piston rod with the interposition of a toggle joint arrangement to a pivoting clamping arm, which with an abutment, im Technical jargon also called "pine”, cooperates. Between clamping arm and abutment (jaw) to be held sheet metal parts are stretched, in order to connect them permanently.
- Devices of this kind are, for example, in the applicant's catalogs "production program”, “clamping technology for professional series production”, “clamping systems, handling, forming technology, punching, flanging, pressure joining, embossing” and in the patents DE 196 16 441 C1 .
- Such a single and multi-stage differential cylinder is to be used as an actuator for pincer-like crushing tools, in which it is desirable that the Anstell- and the release stroke are traversed faster than the subsequent to the Anstellhub working stroke. Therefore, the cylinder chambers, so the bottom pressure chamber and the so-called annulus, when extending the cylinder initially connected to each other with the effect that the displaced during extension from the annulus pressure fluid flows into the cylinder pressure chamber, which flows through the pressure medium fed into the cylinder pressure chamber by the pump Accelerated deployment process accelerating supportive. This switching situation is maintained until the extending piston rod encounters the initiation of the actual working stroke defining resistance.
- This Resistance or the so-called load component leads to a pressure increase in the cylinder pressure chamber, which causes the closing of the inserted into the connecting line between the cylinder chambers check valve, so that the further extension of the cylinder takes place only under the action of the pressure medium fed through the pump in the cylinder pressure chamber, then also correspondingly slower in the now on the cylinder and possibly then on the object acting forces account bearing way.
- the DE 19 41 785 A1 relates to a pneumatically or hydraulically driven power stroke cylinder, in particular for cutting, embossing or pressing tools, wherein the drive power is supplied to the cylinder via a working pressure line and a back pressure line so that the working stroke of the piston is divided into a forward stroke, caused by the back pressure only a correspondingly low differential pressure acts on the piston and a power stroke, in which the back pressure is turned off by valve action, and the full power of the piston drives.
- the differential pressure acting on the piston arises because the same drive energy presses on both sides in opposite directions on different sized piston surfaces.
- the DE 333 903 C describes a hydraulic pressing plant, wherein the plunger is connected to an auxiliary piston and the pressing cylinder with an auxiliary cylinder of smaller volume.
- the auxiliary cylinder is connected to the pressurized water, the pressure cylinder to water under ordinary pressure and both cylinders are connected by a controlled valve with each other in such a way that pressurized water passes only when placing the plunger on the workpiece in the press cylinder.
- the plunger and the auxiliary piston have a top of the auxiliary piston closed by a valve, connected at the bottom of the auxiliary piston by a transverse bore with the press cylinder longitudinal bore in which a control rod is guided, which acts with its upper end on the valve and so far with its lower end protrudes from the plunger that it opens the valve at or immediately before placing the latter on the workpiece and pressure water can pass through the longitudinal bore and transverse bore in the press cylinder.
- the DE 10 2004 027 849 A1 relates to a drive unit, in particular for an injection unit or an ejector of an injection molding machine, with a working cylinder having three pressure chambers, one of which has an acting in the extension direction small effective area, one acting in the extension direction large effective area and an acting in the retraction effective area, and with a valve arrangement for acting on the pressure chambers in each case with high pressure or low pressure.
- the device is characterized by a high-pressure accumulator and a low-pressure accumulator, which are connectable via the valve arrangement with the pressure chambers, wherein the force acting in the retraction effective area and one of the effective acting in the extension direction effective surfaces are subjected to high pressure both during rapid deployment and during rapid retraction.
- the invention has the object of providing a toggle lever device according to the assumed genus in such a way that it works more energy efficient and manages with simple, robust control means for the control of the compressed air to the cylinder chambers.
- Toggle clamps can be used with great advantage in the bodywork of the automotive industry.
- Existing production lines can be provided without structural changes with such toggle lever tensioning devices as are the subject of the invention, thereby reducing energy costs to considerably reduce the operation of such production lines.
- the control of the spool takes place directly through the piston of the drive unit for the clamping arm. This reduces the number of parts and avoids complicated wearing parts.
- the piston valve is space-saving in the cylinder cover, which separates the cylinder, in which the piston is longitudinally displaceable and sealing, separates from the clamping head, arranged longitudinally displaceable and sealing.
- reference numeral 1 designates a cylinder having a cylinder bottom 2 and a cylinder cover 3. Cylinder bottom 2 and / or cylinder cover 3 can be connected by screws (not shown) with the actual cylinder 1 releasably and replaceably.
- the cylinder 1 may be circular in an orthogonal to its longitudinal axis guided cross-section, but also oval, rectangular, flat oval or otherwise designed.
- a piston rod 6 is assigned, via which a clamping arm 7 is moved via a toggle joint arrangement 8.
- the clamping arm 7 interacts with an abutment, not shown, also called jaw, together.
- the basic structure of toggle clamps is state of the art and will not be described here for the sake of simplicity. Devices of this type can be found in the attached bibliography apparent publications are taken, as they are also described in the introduction to the specification of this patent.
- a longitudinal channel 10 which is connected to the cylinder cover 3 end facing compressed air conducting with a transverse channel 11, which opens at one end into the working cylinder chamber 12 and here to a not drawn control system for a suitable fluid supply and - discharge or vent connected.
- This fluid is compressed air, which is available everywhere in the factories and especially in production lines.
- the longitudinal channel 10 At a distance from its other end of the longitudinal channel 10 is connected in compressed air conduction with a arranged in the cylinder cover 3 branch channel 13, while the longitudinal channel 10 is also connected at its end in compressed air-conducting connection with a channel section 14 compressed air conducting, which opens into a chamber 15 fluid-conducting.
- a further channel 16 is arranged, which opens into a cylindrical bore 17.
- This channel 16 is followed by a chamber channel 18, which opens at one end compressed air conducting to the channel 16 and at the other end into the chamber 15.
- a piston slide 19 is guided longitudinally displaceable and sealing, which protrudes with a certain length in a Zylinder Weghubraum 21 and is guided in the chamber 15 with a piston 20 longitudinally displaceable and sealing.
- the chamber 15 is thereby subdivided into two cylinder chambers, wherein in the one cylinder chamber 22 of the chamber channel 18 discharges compressed air, while in the cylinder chamber 23 of the channel portion 14 discharges air pressure.
- the piston slide 19 has a longitudinal channel 24, which extends in the illustrated embodiment coaxially to the longitudinal axis of the spool 19 over part of its length and has an orthogonal to the longitudinal axis extending compressed air, connected to the longitudinal channel 24 branch channel 25.
- the compressed air When introducing the idle stroke (Anstellhubes) in the Y direction, the compressed air in turn propagates through the transverse channel 11 and the channel 10 to the branch channel 13 and also via the channel section 14 into the chamber 15 and acts on the piston 20, whereby this in his Fig. 1 is displaced apparent position, whereupon the cycle described above can be repeated.
- the reference numeral 40 denotes a device only schematically indicated for detecting the position of the piston rod 6.
- This device 40 may be a so-called cassette known from toggle clamping devices, in which the respective position of the piston rod 6, for example via a switching lug 41, can be detected by means of pneumatic switches, microswitches, inductive switches or the like.
- the device 40 may also be arranged in the form of a cassette directly associated with the cylinder 1, for example in a recess thereof, as shown in FIG Fig. 2 is shown, where the device for detecting the various positions of the piston rod 6 and thus indirectly also the angular position of the clamping arm 7 is disposed in a located on the back of the clamping head 42 slot 43.
- This slot 43 may preferably extend in the longitudinal axis direction of the clamping head 42 and thus parallel to the stroke direction of the piston rod 6 or transversely thereto.
- the device 40 seals the slot to the outside largely, for example, liquid and dustproof from.
- the device 40 can also be designed as a so-called adaptive cassette, in which by single or multiple driving certain positions these positions in a memory electronically can be stored and dismantled to assign, for example, a clamping arm 7 different angular positions.
- the device parts 44, 45 may be switches, for example electrical switches or inductive switches, which are damped by the switching lug 41.
- the data is retrieved via a suitable electrical or electronic plug 46 and transmitted via a line, for example to a remote control station, a data processing system or the like. These data may be included in a production control or regulation and may be located in, for example, a production line in the body shop of the automotive industry.
- Reference numeral 47 designates a seal through which the piston rod 6 can be led out of the working cylinder space 1 in a compressed air-tight manner.
