Definitions
- the present invention relates to a novel press table tool substructure for a processing, shaping and / or forming of pressed parts taking place during the actual pressing process.
- GMA common structure
- This common structure serves to carry the actual, depending on the function different widths individual tool modules, which fulfill the functions, especially trimming, forming, forming, embossing, punching, cutting and punching sheet metal parts of various kinds.
- the present invention has set itself the goal of creating a tool base of the type mentioned, which is characterized by a substantial reduction of its own weight, the necessary material and labor and thus the cost and not least the height of the substructure itself. Furthermore, the very significant disadvantage of the existing technology in this field should be avoided, which consists in that for each new overall tool that is intended for the production of a new pressed part, a separate tool base must be recreated and poured with great effort. The various considerations have ultimately led to not make the tool base as a whole, but to replace it with a plurality of system elements, which are adapted to the task of each of the individual tools.
- the new design should be suitable to replace the entire GMA as described above by repeated, so in the long term usable, standardized system elements, ie by individual sub-modules.
- the invention thus relates to a new press table mold base of the type mentioned, which itself forms the press table or can be positioned on the table of a press and carries with - provided for the implementation of different processing operations, different - individual tool modules formed overall tool, and which is characterized in that, starting from the hitherto known concept of a common for each press part to be created construction of the entire tool and for the same purpose built, in particular cast molding press table, independently of each other below the entire tool on a novel press table, especially directly and / or with Distance from each other, positioned side by side, specifically parked on the respective individual tool modules of the overall tool and their or their processing tasks, optionally with scrap discharge openings and / or scrap Abb ransportband and / or the like. Equipped, bridge-like individual substructure modules are provided.
- the invention thus consists in the fact that individual, modularly constructed system elements, which can be combined in any desired way, take the place of the uniform GMA formed so far with an at least partially highly complex casting.
- variable press table or "variable tool substructure” is characterized by flexible, freely positionable and reusable system elements, ie by the individual tool substructure modules that, once invested, in each case substantially all future tool costs cost significantly lower.
- These new, individual tool substructure modules according to the invention can be designed according to the individual tool to be positioned on them in different widths and for the most diverse functionalities, such as e.g. as scrap guiding modules, full substructure modules, die cushion modules, scrap conveying modules, fine cutting pad modules, feeding units and assembly carrier modules and the like.
- functionalities such as e.g. as scrap guiding modules, full substructure modules, die cushion modules, scrap conveying modules, fine cutting pad modules, feeding units and assembly carrier modules and the like.
- This US patent relates to a pure scrap and / or sectionefalladapt istsdorfkeit, which is provided in the form of a tool base on a standard in the US closed press table.
- This concept does not allow the integration of various functional modules as standardized, permanent units, but is designed only for the simplified waste or workpiece disposal of board punching tools for similar part geometries or parts families, as Figs. 22 to Fig. 27 make clear this document. It only compensates for the possibility of discharging the stamped scrap through openings in the press table, which is generally not available in presses of US manufacturers.
- a new press table tool substructure has proven to be advantageous in which the press table (60) and the clamping plate (50) with a plurality of partial openings formed overall opening (601) with central wall (602) and the same supporting Soarmwandungen is formed, and its own , interior space (601) divided by middle wall (602) and side arm walls (603) has a larger total base area which is larger than the area of the overall recess (501) of the clamping plate (50).
- Table I on page 14 shows a summary of the weight analyzes of 19 concretely built tools according to the invention in various orders of magnitude. It has been shown that an average weight reduction of up to more than 38% could be achieved by using the construction according to the invention. In addition, there is the significant advantage that the achievable by the invention, significant height reduction of the pressing tool compared to the high-building, previous GMA in the storage of new tools is quite remarkable.
- a comparatively increased bending and deformation stiffness of the new construction is in particular due to the middle web in the clamping plate and in the Press lower part or table achievable - this has become possible a total of a larger total area of the scrap diarrhea openings thereof.
- FIG. 1 shows an oblique view of a previously known pressing tool as a common structure, GMA, as is the state of the art
- FIG. 2 shows the overall tool according to the invention, whose individual tool modules arranged on a carrier plate are each supported by individual tool substructure modules 3 shows the new press table with clamping plate for the new tool substructure modules
- FIG. 4 shows the combination according to the invention of press table, carrier plate, individual tool substructure modules and individual tool carrier plate
- FIGS. 5 to 9 different individual tool substructure modules FIGS in view from above a tool substructure with total tool, so a common structure according to the prior art

- FIGS. 13 and 15 each show other common tooling structures in accordance with the present invention, with FIGS. 10 and 11, 12, and 13, and 14 and 15, respectively, showing the same overall tools that are used to make various objects.
- Fig. 1 shows a previously common, tool-specific common structure (GMA) 400 as a continuous, uniform, all single tool modules 21, 22, ... 2n united supporting cast construction, where there, as well as in the following figures, the same positioned single tool modules 21, 22, ... 2n together form the total tool 20, which is connected to the according to the requirements of the operation of the individual modules of the entire tool designed, previous, tool-specific designed tool base, which forms the common structure 400.
- GMA tool-specific common structure
- Fig. 2 shows - with otherwise constant reference numerals - as according to the present invention, the hitherto known, specially tool-specifically designed, casting-technically produced, heavy-weight overall tool substructure is replaced by a common support plate 30, to which in the state of the art the same way with the individual tool modules 21, 22, ... 2n formed, known as such total tool 20 - of course releasably - is bound.
- the carrier plate 30 rests on the individual tool base modules 41, 42, 43,... 4n with openings 401.
- the entire tool 20 can be built outside the press, transported easily and as a result of the much lower overall height also store much less space.
- the tool modules 2n are, for example, pinned on the support plate 30 or embedded in recesses of the support plate 30 and screwed. This connection need not be resolved in a press-forming operation for a large number of identical pressed parts unless individual tool modules 2n are removed for maintenance or repair.
- the carrier plate 30 has the significant advantage that it serves as a transport plate for the entire tool 20 from the outset.
- the necessary connection points for lifting means are known in the art and are not shown in detail in FIG.

- the support plate 30 is - according to the prior art - by non-illustrated, firmly attached to her determinants, such as in particular hardened Prism and abutment surfaces and corresponding, each mounted on two outer substructure modules 2n round bolts in the longitudinal and transverse directions mounted on the clamping plate 50 shown in FIG. 3 positionally determined.
- the voltage of the support plate 30 can be done by means also not shown, conventional T-slot screws in T-slots of the substructure modules 2n or other prior art, known clamping elements.
- the individual substructure modules 2n are, as shown in FIG. 4, also secured in position on the clamping plate 50, likewise by means of prisms, contact surfaces and round bolts, and likewise tensioned by known prior art clamping devices.
- the X-Y-position of the entire tool 20 can be precisely adapted to the press installation space, whereby the eccentric load of the press ram in the longitudinal and transverse directions can be optimized.
- variable, standardized system element family of reusable single sub-modular modules 41, 42, 43, ... 4n which can be combined and positioned as required and on the for each individual pressing process of a series of objects can ultimately be fixed in the same constant clamping plate 50.
- FIG. 3 shows - with otherwise constant reference numerals - a invention preferably used to be used clamping plate 50 on the press table 60, here with center web 502 to achieve higher bending stiffness, the positioning and clamping system for the individual sub-modularity 41, 42, 43, ... 4n is integrated in the clamping plate 50.
- a design as a shuttle table concept can be useful.
- the platen 50 is usually positioned on the press table 60 and bolted thereto. After positioning the substructure modules 4n, the actual overall tool 20 is positioned and tensioned on the carrier plate 30 on this clamping plate 50.
- the clamping plate 50 can be both permanently installed, as well as a removable platen 50 or equal to be built together with an exchange press table 60. Provided in press construction, for example rectangular AufspannausEnglishept, T-slots, clamping inserts and mutual projections on the narrow sides of the sub-modules 4n are, since they belong to the prior art, not shown in detail for simplicity.
- the clamping plate 50 is shown in FIG. 3 with T-slots, in which the prior art corresponding clamping elements, in particular T-slot screws or hydraulic clamping elements, can be inserted. This is common in press construction and there are several manual and semi-to fully automatic clamping systems known, which would also be suitable here.
- the transverse struts 503 in the multiply divided scrap diarrhea opening 501 of the clamping plate 50 serve to stabilize the center web 502; the transverse struts 503 closing towards the top, about roof-like slopes are used for safe slipping of the cutting and punching scrap in the likewise multiply divided press table opening 601st
