Definitions
- Pre-preaged flange breakout Building or housing part with such a flange breakout.
- the invention relates to a system and a method for pre-embossing
- Flange outbreaks are required for cable entry in the control cabinet and distributor construction, in particular for floor and wall cabinets, with several configurations being known and customary in the metal sector in the context of metal forming technology.
- components are known on the one hand, on which the flange is punched out in advance so that the flange can be installed directly.
- components are also known in which the respective flange breakout is merely pre-punched, so that before installation of the respective flange, the pre-punched flange breakout on the part of the product user has yet to be knocked out
- CONFIRMATION COPY or must be broken so that the respective flange can be installed.
- the pre-punched flange outbreak can be connected to the respective component via one or more connecting webs and be released and separated from the respective component by their severance.
- the pre-punching over the entire material thickness is performed, so that the NASAde flange is still connected via one or more connection webs with the component, so that the IP protection in question can not be met here, since the resulting gap between Flanschvorstanzung and Component, in particular a cabinet or distributor housing Undefined and insufficient can be closed by a powder coating.
- a process-safe maintenance and guarantee of the IP protection types is thus not guaranteed by means of known designs and methods.
- the invention thus has the object to provide a possibility for an improved flange pre-punching, in which the aforementioned disadvantages are avoided.
- the flange projection stamped in accordance with the invention is characterized in that the flange shape to be broken-out is positively stamped, that is to say peripherally over the entire flange circumference, to only a defined depth and that Techêtde flange so that it is fully connected to the support member.
- the material is not severed at the embossing position between the cutting or embossing edges but at this point laterally displaced and / or compressed, in particular highly compressed.
- the pre-embossment of the flange breakout is carried out from two sides.
- the inventive system for pre-embossment of flange outbreaks comprises control / regulating device and a handling device with at least one first holding device for receiving and holding the component to be prezugargenden and at least one second holding device for receiving and holding at least one tool, wherein the at least one first and second holding device relative to each other in at least two spatial directions are movable and the at least one tool comprises at least one forming knife, characterized in that the interaction of control / regulating device and holding means on a support member, in particular a Wenn Schweizer- and / or distributor housing part, a predeterminable flange shape by means of a to in a predeterminable depth defined in the material, in particular sheet metal, diving mold knife is retractable and pre-embossed, wherein the material at the embossing position between the cutting or embossing edges not severed but at this point laterally displaced and / or compacted below the respective Formessers.
- the contour of the forming blade is configured or chosen such that the cutting burr, which results from the pre-embossing and knocking out of the flange, remains on the worn-out flange.
- the at least one second holding device has two form knives or two second holding devices are provided, each with a forming knife, wherein the two form knives are arranged opposite one another such that the component to be embossed they can be positioned and / or moved through them, so that the embossing can be carried out or effected simultaneously on both sides simultaneously.
- the object is achieved by a method for pre-embossment of flange outbreaks, wherein by means of at least one on a support member, in particular a cabinet and / or distributor housing part, in the respective material, in particular sheet, to a predeterminable depth defined dipping knife a predeterminable flange shape traced and pre-embossed, wherein the material or the material is not cut at the embossing position between the cutting or embossing edges but laterally displaced and / or compacted below the respective form of knife, such that the researcherhyroidde pre-embossed flange shape remains fully connected to the support member.
- the material is not cut at the embossing position as before between the cut edges, but by a deep defined immersion in the material by means of form, is pre-stamped, wherein. the pre-embossing is or can be done from one or two pages.
- the material or the material is laterally displaced at the embossing point, or highly compressed below or between the molding dies.
- the contour of the forming knife can be selected so that the cutting burr, which results from the projection and knocking out of the flange, remains on the knocked-out or broken-out flange.
- the solution according to the invention makes it possible for housing or housing parts, in particular control cabinet and / or distributor housings, housings to be provided with flange knockouts up to IP68, without violating the specified protection class, since the flange knockouts provided in accordance with the solution will be termed absolutely leak-tight until their breakout can or are absolutely tight.
- a switching or distribution cabinet in particular from the low voltage range, with a housing part or housing element with at least one inventively vorge ceremoniesgten Flanschausbruch.
- a construction or housing part in particular a formed from sheet metal or steel sheet construction or housing part for a switching or distribution cabinet, which has a pre-embossed Flanschausbruch according to the features of the invention is also claimed and solves the problem of the invention.
- a building or housing part or a suitably trained switching or distribution cabinet which is formed or manufactured by the claimed method and / or the claimed system or is and has the relevant features, leads to a preferred embodiment of the invention and is therefore expressly in the Disclosure of the present application.
- the invention is in no way limited to control cabinet or distributor housing but rather applicable to any types of sheet metal and / or housing parts and transferable.
- FIG. 1 shows a pre-embossed flange according to the invention of a control cabinet housing part with deeply defined pre-embossing without connecting webs
- Fig. 2 is a detail view of a pre-embossed Flanschausbruches invention
- Fig. 3 a Letteii with knocked out, inventively pre-stamped flange breakout. Flange outbreaks are required for cable entry in control cabinets and distribution boards, especially for floor and wall cabinets.
- Fig. 1 an exemplary trained inventive flange breakout is shown.
- the microphonebachende flange 14 is positively, that is circumferentially over the entire flange circumference, pre-embossed on only one defined and / or predeterminable material depth or thickness by means of at least one forming knife, so that the pre-embossed flange shape 14 thus after the embossing process still fully with the respective component 20, hereinafter also referred to as a carrier component, in particular a housing component, is connected and the respective component and the switching or distribution cabinet formed therewith in this respect is still completely tight and in particular meets the protection class up to IP68.
- a carrier component in particular a housing component
- the material Due to the embossing design by means of forming knife and only to a predetermined material depth, the material is not cut at the embossing position between the cutting o- the embossing edges but displaced at this point laterally and / or compressed, in particular highly compressed.
- the pre-embossment of Flanschausbruches 0 can be carried out from two sides, in which case the pre-embossed flange is still continuous or continuous circumferentially connected to the respective component, in particular a housing part, so that here the IP protection in question, in particular the IP68, at any time is complied with, since a gap between pre-stamped flange and component 20, in particular a cabinet or distributor housing, according to the invention is avoided.
- the outer flange cross-sectional area is formed or limited by the outer edge of the circumferential formation or indentation.
- the inner, laterzanieride actual flange shape or Flanschquerroughs formulation 14 is bounded and formed by the inventively introduced circumferential embossing edge 18.
- Fig. 2 is an enlarged view of the lower right corner region of the already known from Fig. 1 Flanschausbruches 10 is shown. It is clearly evident that the embossing and / or the embossing edge 18 has pierced the base material at any point, but the edge is still fully closed and thus the inner Flanschqueritess composition 14 fully, that is without interruption or without opening, with the flange surrounding the surrounding carrier material and component 20 is connected.
- the respective material is not at the embossing position as before between the
- the material or the material is displaced laterally at the embossing point, or highly compressed below or between, for example, one or two shaping dies.
- the necessary force for knocking out the flange or flange outbreak 10 is the same size at all points and is distributed homogeneously and component-sparingly over the entire or virtually entire circumferential area of the flange break-out 10 or at least a larger peripheral portion, which reduces the loads occurring at one point and one Damage to the respective component is avoided.
- FIG. 3 A corresponding component 20 with knocked out, inventively vorge Georgiagtem flange 22 is shown in Fig. 3. From Fig. 3 seen the deflection of the flange has led to any damage and / or unwanted deformations of the substrate, resulting in particular from the uniform Flanschkanten- or -randverlauf, which is uniform, formed without indentations, corrugations or other such deformations.
- the present invention also encompasses any combinations of preferred embodiments as well as individual design features or developments, provided that they are not mutually exclusive.
