Description

sThe The invention relates to parallel printing modules for the transmission of parallel-guided pressures, on the one hand for operation a guided Ram pressure plate used on a press and on the other hand for clamping workpieces should be.

The Technical application of parallel printing modules is very versatile. Become predominantly these printing modules generally used machine, device and press construction.

One of the most famous parallel printing modules is the principle of the toggle lever, z. B. in a toggle press (see. DE 100 65 255 A1 ).

Usually is the articulation of the toggle lever by means of shaft and bore educated. Such joints usually have high loads withstand.

The Articulated connection through shaft and bore - mostly with bearing bushes provided - forms a major weakness in the transmission of high compressive forces.

They require a lot of installation space, the assembly and disassembly is often problematic because they are - depending on the system design - usually difficult to access. There are also known from the prior art joints, which are not based on the principle of action "shaft bore" (see. DE 33 31 721 C2 . GB 502 872 ).

All in all However, the prior art is based on the this application lying application areas in need of improvement.

• a) die genannten Nachteile beseitigt
• b) eine hohe Belastbarkeit und Wechselbeanspruchung bei kleinstmöglichen Baumaßen realisiert
• c) die fertigungstechnischen Belange montagefreundlich und rationell gestaltet
• d) die Wartungsintervalle verlängert und
• e) durch Standardbauteile ein vertretbares Preis-Leistungsverhältnis geschafft

werden.The object of the invention is to provide a parallel printing module in question, in which

• a) eliminates the disadvantages mentioned
• b) realized a high load capacity and alternating stress with the smallest possible dimensions
• c) the manufacturing requirements are easy to install and rational
• d) the maintenance intervals are extended and
• e) managed by standard components a reasonable price-performance ratio

become.

These The object is solved by the features of claims 1 and 3, respectively.

Further Embodiments are the dependent claims refer to.

• 1. In Grundstellung sind die Gelenkstücke ausgeschwenkt
• 2. Durch Verschieben der Druckschwinge werden die Gelenkstücke paarweise in Strecklage gebracht.
• 3. Hierdurch erfolgt eine parallele Hubbewegung, auch bei außermittiger Belastung der Stößeldruckplatte.

The functioning of a parallel printing module in question:

• 1. In the basic position, the joint pieces are swung out
• 2. By moving the pressure swing the joint pieces are brought in pairs in an extended position.
• 3. This results in a parallel lifting movement, even with off-center loading of the plunger pressure plate.

The well-tried Principle of a toggle lever - in terms its high pressure ratio - can thus, due to the massive design of joint piece and bearing segment, centrally over the total support width completely exhausted become.

In the drawings, various embodiments of the invention are shown, wherein from the 1 - 4 and 10 essentially the technological background is removable.

1 shows a parallel pressure module for the transmission of parallel guided pressures, consisting of 4 equal - massive joints 1 , from 4 equal - massive bearing segments 2 (top / bottom), from 2 equal - massive bearing segments 3 (in the middle), from pressure swingarm 5 with bolted bearing segments 3 , made of condyle 6 for attachment of a hinged z. B. hydraulic cylinder, from 2 same bearing receptacles 14 in which the bearing segments 2 (top / bottom) are screwed.

Clear It should be recognized that all bearing segments and joint pieces for optimal pressure ratio have the same width that all joints in stretched Condition insoluble stay connected with each other, that all bearing segments are stuck shouldered in a secure position, that - in view A - the Pressure swing consists of 2 equal strips and thus manufacturing technology easy to produce.

The 2 - 4 show a parallel printing module after 1 , built into a press for actuating a guided ram pressure plate.

2 shows a parallel printing module in the open state of the press, in the basic position left, between a fixed frame part 9 and a movable plunger pressure plate 10 by means of the fixed bearing mounts 14 is arranged.

Here is the ram pressure plate 10 z. B. guided laterally and vertically in a fixed frame part. This can be realized by guide columns or guide plates.

The preferably hydraulic drive element of the pressure swing is with the fixed frame part z. B. connected bolted connected.

The ram pressure plate 10 - here in columns 8th guided - performs in a right-left movement of the pressure swing 5 a parallel lifting movement up and down.

3 shows, as well as in 2 shown, the executed movement of the pressure swing 5 in basic position right.

4 shows the parallel pressure module in the closed state of the press.

Here it becomes clear that the pressure swing 5 in a movement from basic position left to basic position right performs an up and down stroke, with the same pivot angle of the joint piece 1 represents an equal double stroke and at the same time the plunger pressure plate 10 once moved up and down.

at Unequal swivel angles Right / Left can this up and down different sizes and be functionally advantageous.

5 now shows an inventive parallel-pressure module according to the main claim.

Shown is the closed state of the press, with movable bearing segments - in the middle - 3 , which preferably in angular execution in guide rails 12 are guided.

The pressure swing 5 is guided linearly. The Doppelhubeffekt - as with 4 visible - is displayed on the bearing segments - in the middle - 3 transfer.

Nothing changes at the parallel principle. System associated with linear guided pressure swing 5 demonstrate 5 / 6 / 7 clearly that the bearing segments - in the middle - 3 to take the up and down lift.

6 shows the situation in basic position Links - Open-, It. to the description 5 , It can be clearly seen that with linear guided pressure swing 5 , a parallel shifting of the bearing segments - in the middle - 3 he follows.

7 shows the situation in the basic position right - open-, it's the description 6 ,

8th shows 2 parallel pressure modules placed as possible standard components in series, with a coupling piece 7 the pressure swing 5 combines.

Here it should be shown that z. B. a large-scale ram pressure plate 10 can be fitted over the entire surface with several parallel printing modules. Between the fixed table top 11 and the movable plunger pressure plate 10 could z. B. also eccentrically positioned tools mounted. An undesirable tilting of the parallel lifting movement is thus eliminated.

9 shows the state of the art, the system-like principle of a toggle It. Description on sheet 1 ,

10 shows a parallel printing module in zur 1 Alternative design for an application clamping technology type in the open state, for z. B. the calibration of a square tube.

Here it should be clarified that the pressure swing 5 can also be designed to act radially. Likewise the bearing segments - in the middle - 3 can have only one bearing, which halves the stroke.

For the bearing segments - below - 4 it can be seen that they are in the warehouse 14 guided evenly to the central center can move back and forth.

11 shows a variant of an embodiment of a parallel printing module according to the invention for clamping workpieces according to claim 3, here only by way of example as an application for the all-round central clamping a square tube.

Here it should be clear that the movement of the pressure swing 5 radially or linearly guided, with the same principle of action also independent of time, - optionally - can be individually, repeatedly or jointly clocked.

12 shows in particular the preferably production engineering design.

Here it should be clear that the main body of the bearing segments - in the middle - 3 made as a turned part, can also be round. The same applies to the bearing segments - above - 2 , or the bearing segments - below - 4 ,

The pressure swing 5 can be provided with holes that selectively the bearing segments - in the middle - 3 , screwed or in fixed guide bushings 12 slidably record.

13 shows a linear pressure module with 2 joints in the bearing segments 2 / 3 ,

Here should be shown that by the compact arrangement on the smallest Room transfer high loads can be.

Furthermore, it is worth noting that in linear guided design of the pressure swing 5 Both sides of a parallel spreading movement arises, the z. B. can be used for double-sided clamping tasks.
