Description

"Hydropnevimatic device and kit"

State of the art

Hydropneumatic devices such as pneumo-hydraulic drive systems, in particular with integrated pressure transmission are known. Such devices are used for example as press arrangements for different tasks, for example for pressing or pressing, joining by forming or for clinching, clinching,

Rivets, punch rivets, solid or semi-hollow punch rivets.

Essential components of a hydropneumatic device are, for example, a translator part with a linearly movable translator piston and a working part, wherein in the working part of a working piston performs a lifting movement while working. The working piston is usually moved either in a rapid rapid traverse either pneumatically or hydraulically to a desired position to the front, wherein after striking a component, a power stroke begins. This is in the translator part of, for example, pneumatic low pressure of 2 to 10 bar, which acts on the booster piston and moves it so that hydraulic fluid from the translator part flows into the working part, a hydraulic high pressure of for example 250 to 400 bar generated on a

hydraulic surface acts on the working piston and moves it, so that a high pressing force is generated during the power stroke. With a return stroke of the working and Übersetzungserkolbens, in a direction opposite to the movement of the working or

The translator piston takes place during the express and power stroke, the Working and the booster piston brought into a starting position, which in particular pneumatically by switching an air pressure on a return stroke side of the two pistons of

Working part and translator part takes place.

The working part and the translator part are about one

Connecting portion hydraulically coupled to each other, whereby in a connecting line of the connecting portion, a bidirectional passage of hydraulic fluid between the working part and the translator part is provided. The connecting line connects a hydraulic

Connection point on the working part with a hydraulic

Connection point on the translator section.

In a hydropneumatic device, the components or the working part and the translator part respectively

be designed coordinated. Starting from a considered configuration, each change in one of the two components causes a change in the other component. A change may be due in particular to the adaptation of a hydropneumatic device to other delivery variables such as pressure and / or stroke path sizes.

The aim of the present invention is to improve the economy of the devices mentioned,

especially with regard to different designs of hydropneumatic devices.

This object is solved by the independent claims.

In the dependent claims advantageous variants of the invention are shown.

The invention is initially based on a hydropneumatic device with a pressure boosting, wherein the

hydro-pneumatic device having a working part with a working piston guided in the working part and a translator part with a translator part guided in the translator part, wherein a connecting portion for a hydraulic coupling of the working part and the translator part, which is a connecting line for a passage of

Hydraulic fluid between the working part and the

Translator part provides. An essential aspect of

Invention is that the connecting portion comprises an at least substantially rigid, on the working part and the translator part mountable adapter component, in the interior of the connecting line is formed, wherein in the assembled state of the adapter component on the

Connecting line one at the working part laterally existing opening of a hydraulic space of the working part with an opening laterally present on the translator part

Hydraulic space of the translator part is connected.

A laterally existing opening means in this

Context that the opening, for example, in one

circumferentially the working or booster piston enclosing outer housing section z. B. a shell-housing section is present or a hydraulic space inside the Arbeitsbzw. Translator parts ends there. Thus, a lateral access is provided with a direction which is at an angle to the longitudinal direction of the working or booster piston. The connecting line in the

Adapter member closes in the assembled state, respectively with the corresponding ends to ends of a line or

Hydraulic chamber section in the working part and in the translator part.

With the lateral connection can be a frontal

Housing section of the working or translator part remain free of an opening or of the adapter component, which z. B. in view of a reduced overall length of the working and / or translator part is advantageous.

With the hydropneumatic device according to the invention, an advantageous standardization of the components

provided. In particular, a production with high batch sizes is advantageously possible. So far, any change in one of the components of the hydropneumatic device, depending on the design of the particular hydropneumatic device, also requires one

Change in the other components. This is due to constructive relationships explained in more detail below

specified. For a given number of different hydropneumatic devices, it is necessary to select for each of the components exactly one associated type of other components.

For the design of a hydropneumatic device, for example, a total stroke of the hydropneumatic

Device basic. The total stroke or the maximum possible stroke length results from the maximum possible rapid stroke and the maximum possible power stroke of the working piston. With a maximum possible stroke length of the working piston and the total length of the working part is determined. For the lifting movement of the working piston in turn is in a storage space in

Translator part a the total stroke of the working piston

corresponding volume of oil required. In addition, for a desired power stroke on the working piston to provide a pre-auszulegender stroke of the booster piston in the translator part.

Thus, for the reasons mentioned, the working part and the translator part must each be individually matched to one another. Any change in any of the "total lift" and / or "power stroke" dimensions will cause a change in the length of the overall device or hydropneumatic device, and thus each of the

several affected components on the working part and on the translator part by itself. For a stroke or length change usually has the working part by at least one

For example, the intermediate piece can be lengthened in order to be able to adapt the working part to the likewise differently predefinable length of the associated translator part. Also, the connection section, which so far in the frontal

Endbereich of the working and translator part followed, has to be adjusted so far. These measures or these

Length dependence of the working part and the translator part is for a standardization of components or a Production with larger batch sizes disadvantageous.

These disadvantages are eliminated according to the invention. With the respective lateral connection of the adapter component, the change in length in the translator part does not affect the working part and vice versa. Compared to the previous approach only comparatively few structurally graded components for the compilation of a desired number of gradations in the design are required. Of the

Manufacturing and storage costs are compared to the previous situation significantly lower and therefore economical

advantageous.

With a comparatively significantly reduced set of a component, wherein the set consists of constructive gradations of components with the same basic structure or components differing from the construction volume, the same design width can be covered, for which a large number of components has hitherto been necessary. For example, with regard to the hitherto necessary total number of components, according to the invention, about one third of components can be used to cover the corresponding combinations.

In particular, it is advantageous that the combinations are largely feasible by differently designed adapter components, which are structurally relatively simple compared to the working and translator part. For a wide diversification of the design of the overall arrangement or the hydropneumatic device, for. B. what concerns different total or power strokes, only comparatively few differently designed translator parts are needed z. In a set of types of translator parts. An even greater range of design possibilities can also be achieved by, in particular, a few differently configured working parts in a set of types of working parts.

In particular, according to the invention, a coupling principle

be provided, after which the working and translator parts are carried out standardized, so that any Combination of the respective translator parts with the respective working parts to correspondingly different

hydropneumatic device is possible.

It is particularly advantageous that with the invention, a working and translator part in different ways, for example via a rigid system or a system with flexible connecting means is hydraulically coupled.

Thus, any combination of

differently sized but in the basic structure similar translation parts with at least one type of working part economically advantageous possible.

Further, it is advantageous that the adapter component is designed such that the adapter component is supported in the assembled state with opposite to the adapter component existing main sides of the working part and the translator part.

In particular, the adapter component is about his

opposite main sides supported flat on also flat or planar counterparts on the working part and translator part. The opposite main sides of the

Adapter components are configured in particular similar. The counterparts in the translator and working part are preferably designed similar. Thus, the attachment or assembly of the adapter component or the assembly of the

hydropneumatic device particularly effective and easy.

The main pages on the adapter component and the associated

Counter sections on the working and translator are in the assembled state of the adapter component together in a surface contact, in particular z. B. by mutually adjacent planar surfaces which are pressed against each other. Thus, a high tightness can be ensured, so that it is ensured that no hydraulic fluid leaks. In addition, advantageously over the surface support a comparatively high stability in the connection region of the translator part with the working part and thus also the Overall arrangement achieved.

Basically, a non-planar support z. B. on only reduced support sections on the

Adapter component or on the working and / or on the translator part possible.

It is also advantageous that on the working part and on

Translator part is provided in the longitudinal direction considered end portion on which the adapter member is supported in the assembled state. The support is made in particular by two-dimensional pressing. An end section can

For example, be a separate part of the Arbeitsbzw. Translator parts attachable thereto. As a rule, viewed on a basic body of the working and the translator part in the longitudinal direction, in each case on the end face

Longitudinal end an existing section. In particular, the base body comprises a housing section with the working or booster pistons guided inside and a pneumatic or

Hydraulic chamber. An end section closes one end of the

Body tight. At the other end of the base body, the other end portion provides a line section, via which hydraulic fluid from a hydraulic chamber in

Interior of the body z. B. the translator part is guided on a lateral opening outside of the end portion, from which in the assembled state of the adapter component

Hydraulic fluid can flow through the adapter component and passes through an opening at the end portion of the working part in a hydraulic space of the main body of the working part and can flow back again.

The two end-side end portions on a base body are preferably separate components, for example end flanges for example cylinder cover, and can, for. B. with four elongated tie rods, which are longitudinally pressed against the base bodies at a distance against the front ends of the base body pressed. For this purpose, nuts can from the outside on a matching male threaded portion at the ends of the tie rods, the projecting through openings at least one End section rich, be screwed. According to an advantageous embodiment of the

Subject matter of the invention, the adapter component is designed substantially as a cuboid component, with prepared attachment openings through which fastening means for mounting the adapter component on the working part and on

Range of translations. Thus, the production of the

Adapter components comparatively simple and economically advantageous. The fastening means preferably extend laterally completely through a width of the adapter component, in particular perpendicular to the opposite main sides in anchoring openings on the working and translating part. In this way, the fastening means such. B.

Screwing means in the assembled state of the adapter component in

normal or perpendicular direction to the main sides and to planar counterparts aligned at the end portions. For this purpose, corresponding through holes or a

to provide a corresponding hole pattern for the fastening means in the adapter component, preferably in the area around a respective passage opening in the main sides for a passage of hydraulic fluid between the

Adapter component and the translator or working part.

Advantageously, four screws are provided for the connection of the adapter component with the translator and the adapter part, whereby a total of eight screws for the complete adapter component mounting are necessary.

An advantageous variant of the subject invention is characterized in that the end portion on the working part and the end portion on the translator part on the associated

Mounting holes on the adapter component for mounting the

Adapter component is tuned to the working part and the translator part with the fastening means. This is a the

corresponding hole pattern on the adapter component corresponding

Provide hole pattern on the corresponding counter section.

Particularly preferably, the hole pattern on the one main side of the adapter component, which is provided for connection of the adapter component on the translator part, coinciding with the hole pattern on the opposite main side of the adapter component, which is provided for connection of the adapter component on the translator part. With the uniform hole pattern on the main sides of the adapter component of course, the associated hole pattern on the translator part and the working part is uniform. Thus, it is advantageously possible, an adapter component with a

Main page either on the translator part or the

To mount working part. In addition, when choosing a

corresponding or symmetrically shaped hole pattern attachment of the adapter component in different twisted orientation possible, for. B. a twisted by 180 degrees position of the adapter component starting from a first

An attachment orientation and a rotation about an axis, which leads centrally through a hydraulic fluid opening in a main side of the adapter component. This can be on

Advantageously, the orientation of the translator part relative to the working part in the hydropneumatic device can be varied.

Preference is given to both openings of the connecting line in the adapter component, wherein an opening is present on each of the two main sides, each provided four through holes for a penetration of the fastening means, which are uniformly offset from each other circumferentially around the opening.

It is also advantageous that the end portion on the working part and the end portion on the translator part in each case similar for mounting the adapter component on the working part and on

Translator part are formed. Thus, the adapter component with a main side either on the working part or on

Translator part for assembly in plant be brought.

Further, it is advantageous that the connecting line in the adapter component has a connecting line section, which in the assembled state of the adapter component in

Longitudinal direction of the translator part and the working part

extends. Especially when the longitudinal axes of

Translator parts and the working part at least approximately are aligned parallel in the assembled state of the adapter component, a distance in the longitudinal direction of the translator and working part between the over the connecting portion or the adapter member to be connected openings in

Working part and translator part by this

Connecting line section to be overcome.

Length differences between the translator and the

Working part, which is the case regularly, can do so

be compensated. For this purpose alone is the corresponding length of the connecting line section or possibly the

Design adapter component. The width of the adapter component can be unaffected by each remain the same. Thus, using a set of different types of adapter components that are only in the length of the

Connecting line section or the adapter component

differ, a lateral distance of translator and working part equal, in particular, the lateral distance can be kept relatively low. The lateral distance is in particular determined solely by the width of the adapter component, or by the distance between the two main sides of the adapter component, which in turn depends on the diameter of the adapter

Connecting line section and the thickness of

Wall sections of the adapter component depends, the

Connect wall sections in the relevant direction on both sides to the connecting line section.

In the assembled state is thus the working part and the

Translator part in a width direction relatively close to each other positioned, bringing the entire

Advantageously, the hydropneumatic device is compact in width.

The invention also relates to a kit comprising components of a hydropneumatic device for providing a hydropneumatic device, which comprises a translator part and a working part hydraulically coupled thereto via a connecting portion, wherein the kit comprises several

different types of the translator part and at least one type of the working part and a set of types of a working part An adapter component, wherein a hydraulic coupling of any type of the translator part with the at least one type of the working part by a suitable type of

Adapter component from the set of types of the adapter component can be realized, wherein an adapter component is designed as a substantially rigid component.

The adapter component preferably represents the complete

Connecting portion between the translator part and the

Working part ready, in particular, there are no flexible

Line sections such. B. in a hose connection available.

So far, hydropneumatic devices are depending on

Use case or in terms of desired maximum

Force values and strokes of the working piston assembled, with each individual translator part to the respective

Working part is to be agreed. An adaptation of the whole

Systems usually makes an adjustment of each

Working part and the translator part or possibly other components such as the connecting portion necessary. With the kit according to the invention, the advantages already mentioned above for the hydropneumatic device are realized with regard to economic advantages.

It is particularly advantageous that the set of types of the adapter components comprises different adapter components, wherein each adapter component of the several different adapter components in each case on one of the different

Translator parts and the at least one working part are designed to be coordinated, wherein only by selecting a suitable adapter component from the set of types of

Adapter components and their mounting to the relevant

Translator part and the relevant working part

desired combination of a translator part of the plurality of respectively different translator parts with the at least one working part.

With the adapter components, so by mounting on the working and translator part, are several

differently configured hydropneumatic devices available without any adaptation to the

Working and translator part is necessary. It is only

comparatively few differently designed

Translator parts, a set of types of adapter component and only one working part or only a few differently designed working parts needed. So far, the provision of corresponding hydropneumatic devices is possible only with a much higher cost of components or for warehousing and with a higher workload. In particular, the provision of the set of types of the adapter component is relatively less expensive than a conversion or a fanning of different working and

Translator parts.

It is also advantageous that an adapter component from the set of types of adapter components is adapted to a mounting portion on a translator part and a working part, that the assembly of the adapter component on the translator part and the working part in each case via at least one laterally extending through the adapter component connecting element , As a connecting element is in particular an elongated or

slim plug-in element or a connecting screw and the like in question. In particular, several, for example, four connecting screws are provided, each

adapter side corresponding through holes and

Working part side or translator part side openings with anchoring sections or internal thread are present.

Advantageously engages in the assembled state of

Adapter component, a first connecting element in a

prepared opening in the mounting section of

Translator parts and a second connecting element in a prepared opening in the working part. Thus, a similar connection arrangement of the adapter component to the working part and the translator part is given. This is with regard to the assembly or on the provision of appropriate fasteners as well as for Production of the adapter component and the corresponding

Counter sections on the working part and translator part advantageous.

Finally, it is also advantageous that a set of types of hose adapter component that has a flexible

Connecting line portion is provided, wherein the hydraulic coupling of any type of

Translator parts with the at least one type of working part optionally with a suitable type of adapter component or with a suitable type of hose adapter component of the set of types of hose adapter component is feasible. So in principle the advantages for over flexible

Line sections connected components of

hydropneumatic device or one over larger

Distances from each other remote attachment of working parts and translator part realize. It is advantageous that the formation of the at least one working part and the

Set of types of compiler components remains unaffected.

Preferably, there is not only one type of working part, but a set of types of working parts in the kit.

According to the invention connected via, for example, high-pressure hoses single and multiple systems can be advantageously realized. A simple system is characterized by exactly one

Translator part and exactly one associated working part, which are hydraulically coupled together. One

Multiple system consists of a translator part, which is hydraulically coupled with several working parts, which

in particular via flexible connection systems. This can be all working parts or even individual

Working parts of the several working parts are hydraulically connected by the translator part.

With the kit according to the invention, it is possible with a comparatively small number of differently configured working and translating a wide range

Combinations of hydropneumatic devices with to realize different total and power strokes.

According to the invention, all types of working and

Translator parts with a standardized

Bolt hole pattern performed for both the

Screwing to a firmly connected hydropneumatic device part as well as for the connection of one or

several hose systems, for example via a special hydropneumatic coupling to a hose system is suitable.

For example, for each working part of a set of types of working parts a translator part can be assigned, wherein the translator part with a compiler jump

is trained. A compiler jump occurs when the diameter of the translator part is one dimension larger than the diameter of the working part.

This is an overall length of the hydropneumatic device and a Eilhubvolumen to the respective working part

tunable. Thus, different designs can be realized, which, depending on the size, for example, 12 to 15

Millimeters have Kraftstub. For smaller sizes and translator parts are designed coordinated, which has a total stroke of 100 millimeters and a power stroke of 6

Allow millimeters.

It is also possible, on a considered working part optionally a translator part with two or three

Grow translator jumps.

For example, a power stroke can be between 20 and 100

Be provided. The necessary rapid stroke volume is sufficient due to the dimensioning described above.

In addition, for each type of translator parts one can

maximum length, which corresponds to the maximum buckling length of a

Plungers the hydropneumatic device is designed to be tuned. The rapid stroke volume results from this a plunger length in a high pressure tube.

With the adapter component, so to speak, only a single length-dependent component in a hydropneumatic

Device installed. In this case, the translator part for

Working part both in standard design, according to which

Translator part is aligned downward, as well as in a so-called Z-design are formed, in which the translator part extends upward. Also a version rotated by 90 ° is mountable.

All combinations of translator parts with working parts can also be done with a total stroke adjustment. There, the total stroke can be set variably on the hydropneumatic device itself, for example by manually operated adjustment means.

An attachment of other functions such as a cutting impact damping, Einpressdämpfung, distance measurement, etc. is easily possible in the kit according to the invention or the hydropneumatic device according to the invention.
