DE10233254A1 - Parallel pressure module for transferring pressures comprises two solid articulated pieces mounted in bearing segments and when connected produce an approximately play-free non-releasable articulated connection - Google Patents

Abstract

The parallel pressure module consists of a pressure swing bar (5) and two pieces of solid articulated joints (1) arranged in pairs opposite one another and mounted in bearing segments at the top (2), centre (3) and bottom (4) so as to produce in the connected state a practically play-free non-releasable articulated connection. All the bearing segments can be selectively screwed together or guided displaceable to each other depending on the function.

Description

The technical area of application of Parallel printing modules is very versatile. Most of these printing modules used in general machine, device and press construction.

One of the best known parallel printing modules is the principle of the knee lever, e.g. with a toggle press.

According to the current state of the art the operating principle is through an articulated connection of the toggle levers by means of shaft and bore. Such articulations must be in usually withstand high loads.

The joint connection by shaft and drilling - mostly still provided with bushings - forms an essential weak point in the transmission of high pressure forces.

They require a lot of installation space Assembly and disassembly is often problematic because - depending on Plant design - mostly difficult to access are.

Walkthrough

• A) The parallel pressure module, preferably hydraulic actuated, consists essentially of at least 2 pieces opposite each other massive joint pieces, the one-sided in a hydraulically operated parallel swing arm 2 bearing segments - in the middle - supported are.
• B) 2 joint pieces are in the storage segments - above - e.g. in a bearing mount held on one side with a fixed frame part connected is.
• C) 2 joint pieces are in the storage segments - below - e.g. in a bearing mount held on one side with a movable Ram pressure plate connected is .
• D) The movable plunger pressure plate is e.g. guided laterally and vertically in a fixed frame part. This can be done by guide pillars or guide plates be realized.
• E) The drive element of the pressure rocker is with the fixed Frame part e.g. articulated screwed connected.

How it works of the parallel printing module

• 1. In the basic position, the joint pieces are swung out.
• 2. By moving the pressure rocker, the joint pieces become in pairs brought into stretched position.
• 3. This results in a parallel stroke movement, even with off-center Load on the ram pressure plate.

The tried and tested principle of a toggle lever - in terms of its high pressure ratio - can due to the massive design of the joint piece and bearing segment, centrally via the total support width gone, fully exhausted become.

Various exemplary embodiments are shown in the drawings illustrated the invention, namely

1 shows a parallel pressure module in the open state, consisting of 4 identical - solid joint pieces 1 , from 4 identical - massive bearing segments 2 (top / bottom), from 2 identical - massive bearing segments 3 (middle), made of pressure rocker 5 with screwed bearing segments 3 , from joint head 6 for fastening a hinged hydraulic cylinder, for example, from 2 identical bearing mounts 14 in which the bearing segments 2 (top / bottom) are screwed tight.

It should be clearly recognized that all bearing segments and joint pieces for optimal pressure translation have the same width that all Articulated connections remain undetachably connected to one another in the stretched state, that all Bearing segments firmly shouldered and held in a secure position be that - in view A - the The pressure rocker consists of 2 identical strips and is therefore manufactured is easy to manufacture.

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

The plunger plate 10 - in columns 8th guided - takes place with a right-left movement of the pressure rocker 5 a parallel lifting movement up and down.

3 shows, as in 2 shown, the executed movement of the rocker arm 5 in basic position right.

4 shows the closed state of the parallel printing module. Here it is clear that the pressure rocker 5 when moving from the basic position left to the basic position right, performs an up and down stroke that works with the same swivel angle of the joint piece 1 , represents an equally large double stroke and the ram pressure plate in the same cycle 10 once moved up and down.

In the case of unequal swivel angles right / left, this up and down stroke can be of different sizes and functionally advantageous his.

5 shows, in contrast to Fig 1 to 4 the closed state, with movable bearing segments - in the middle - 3, which preferably in angular execution in guide rails 12 are led.

The rocker arm 5 must be linear in this version. The double stroke effect - as with 4 visible - is transferred to the bearing segments - center - 3.

This does not change the parallel principle. System-related with linearly guided pressure arm 5 demonstrate 5 / 6 / 7 clearly that the bearing segments - in the middle - 3 , take over the lifting and lowering.

6 shows the situation in the basic position left - open -, according to the description 5 , It can be clearly seen that with a linearly guided pressure swing arm 5 , a parallel displacement of the bearing segments - in the middle - 3 takes place.

7 shows the situation in the basic position right - open - according to the description 6

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

Here it should be shown that, for example, a large plunger plate 10 can be fully equipped with several parallel print modules.

Between the fixed table top 11 and the movable plunger pressure plate 10 For example, tools positioned off-center could also be installed. An undesired tilting of the parallel lifting movement is therefore ruled out.

9 shows to the state of the art the system-like principle of a toggle according to the description on sheet 1

10 shows an application of clamping technology in the open state, for example for the calibration of a square tube.

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

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

11 shows, also how to 10 described, an application for, for example, central clamping of a square tube on all sides.

Here it should be clear that the movement of the pressure rockers 5 radial or linear guidance, with the same operating principle also independent of time, - optionally - can be clocked individually, several times or together.

12 shows, especially the preferably manufacturing design.

Here it should be clear that the basic body of the Bearing segments - middle - 3 as Turned part made, can also be round. The same applies to the bearing segments - top - 2, or the bearing segments - below - 4

The rocker arm 5 can be provided with holes, which optionally the bearing segments - in the middle - 3 , screwed or in tight guide bushings 12 slidably record.

13 shows a linear pressure module with 2 articulation points in the bearing segments 2 / 3

It should be shown here that through the compact arrangement can transfer high loads in the smallest space can be.

It is also worth mentioning that in the case of a linearly guided design, the pressure rocker 5 , there is a parallel spreading movement on both sides, which can be used, for example, for double-sided clamping tasks.
