Abstract

The parametric construction of tools for processing sheet metal is a 3D computer model of reference tool constructions for processing sheet metal without tool forming elements and is aimed at further construction of cutting, tractional, extracting, calibrating, trimming, punching and bending tools. Such a construction includes all vital elements of tools for processing sheet metal, which are defined by parameters as well as standardised parts, which are part of the base of parametrically defined elements and feature mutual relation-based links.

Description

Parametrična konstrukcija orodij za preoblikovanje pločevlneParametric construction of toolboxes

Izum se nanaša na področje strojništva, bolj podrobno pa področje orodjarstva, in sicer konstruiranje orodij za preoblikovanje pločevine.The invention relates to the field of mechanical engineering, and more specifically to the field of toolmaking, namely the design of tools for sheet metal forming.

Predmet izuma je parametrična konstrukcija orodij tj. prireznih, vlečnih, kalibrimih, upogibnih, obrezovalnih, prebijalnih in drugih orodij za preoblikovanje pločevine. Izum je sestavljen iz več referenčnih konstrukcij, ki pa skupaj pokrivajo večino konstrukcijskih značilnosti posameznih vrst orodij. Skonstruirana so referenčna orodja, ki so ob uporabi gradnikov z parametri in relacijami asociativno tako definirana, da lahko imamo z vnosom parametrov v kratkem času osnovo za nadalno konstruiranje kateregakoli preoblikovalnega orodja. Ker že na samem začetku konstruiranja orodja dobro vemo za kakšno vrsto orodja bo šlo, med razpoložljivimi izberemo primemo referenčno konstrukcijo. Takšne parametrično določene referenčne konstrukcije orodij ne vsebujejo oblikovnih delov izdelka, kar bi lahko bil eden od potrebnih podatkov o velikosti orodja in njegovih delov. Podatke o orodju, njegovo velikost in velikost njegovih sestavnih delov bo tako določil in vnesel v računalnik konstruktor, na podlagi teh podatkov pa bo računalnik generiral računalniški model želenega orodja, ki bo služil kot osnova za nadalno konstruiranje orodja.The object of the invention is the parametric construction of tools, i.e. cutting, drawing, calibrating, bending, trimming, punching and other tools for sheet metal forming. The invention consists of several reference structures, which together cover most of the structural features of each type of tool. Reference tools have been constructed and, with the use of parameter and relation building blocks, are associatively defined, so that by entering parameters in a short time, the basis for the continued design of any transformation tool can be created. Since we know very well at the very beginning of the construction of the tool what kind of tool it will be, we choose the reference construction from the available ones. Such parametrically determined tool reference constructions do not contain the form parts of the product, which could be one of the required data on the size of the tool and its parts. The data about the tool, its size and the size of its components will thus be determined and entered into the computer by the constructor, and on the basis of this information the computer will generate a computer model of the desired tool, which will serve as a basis for the further construction of the tool.

Pri izdelavi posameznih parametrično določenih referenčnih konstrukcijah sem precejšno pozornost posvetil temu, da nisem omejil konstruktorja, ki bo takšno konstrukcijo uporabljal kot osnovo za konstruiranje orodja. Pri sestavnih delih konstrukcije mora biti možno izvesti vse kombinacije, ki bi se lahko pojavile pri konstruiranju orodja za preoblikovanje pločevine. Pozicije posameznih delov orodja na primer vodil so parametrično določene glede na njihovo velikost, vendar ima konstruktor možnost, da jih zaradi razporeditve prostora na enostaven način prepozicionira. Poleg premikanja morajo dopuščat tudi vrtenje okoli svoje osi, saj se na ta način tudi prijemala vodil vrtijo okoli osi vodila in lahko v primeru pomanjkanja prostora le tega optimiziramo. Razumljivo je da se morajo vrteti prijemala vseh štirih vodil hkrati in to ne v isto smer, ob upoštevanju daje eno vodilo zamaknjeno zaradi preprečevanja napačne sestave zgornjega in spodnjega dela orodja. Skratka parametrično določeno referenčno orodje, ki je predmet izuma je zasnovano tako da dopušča maksimalno fleksibilnost, enostavnost in zanesljivost uporabe, konstruktoga pa ne omejuje pri uporabi takšnega parametrično določenega modela orodja kot osnovo za konstruiranje preoblikovalnega orodja.In making individual parametrically defined reference structures, I paid considerable attention to the fact that I did not limit the constructor who would use such a construction as a basis for constructing the tool. For components of the structure, it must be possible to carry out all combinations that may occur in the construction of the sheet metal forming tool. The positions of the individual parts of the tool, for example guides, are parametrically determined according to their size, but the constructor has the ability to easily position them due to the layout of the space. In addition to moving, they must also allow rotation about their axis, since in this way the gripper arms rotate around the axis of the guide and in the event of a lack of space it can be optimized. It is understandable that the grips of all four guides must rotate at the same time, and not in the same direction, given that one guide is offset to prevent misalignment of the top and bottom of the tool. Briefly, the parametric reference tool of the invention is designed to allow maximum flexibility, ease and reliability of use, but does not limit the construct when using such a parametrically defined tool model as a basis for constructing a forming tool.

Osnova za izdelavo parametrično določenih orodij je baza parametrično določenih sestavnih delov oziroma gradnikov orodij. Sestane dele iz baze koristimo pri izdelavi parametrično določenega orodja, pri čemer se struktura sestavnih delov, parametri in relacije ohranijo. Dodati je potrebno še parametre in relacije, ki se nanašajo na pozicijo pravkar dodanega sestavnega dela. Pri tem seveda ni nujno da so vsi sestavni deli, ki se nahajajo v bazi vključeni v osnovno parametrično konstrukcijo. Sestavne dele orodja, ki se ne uporabljajo v vsakem orodju lahko sproti, v fazi konstruiranja konkretnega orodja vključimo v konstrukcijo orodja.The basis for the production of parametrically determined tools is the database of parametrically determined components or tool building blocks. The assembled parts from the base are used in the construction of a parametrically defined tool, while maintaining the structure of the components, parameters and relations. It is also necessary to add parameters and relations that relate to the position of the component just added. Of course, it is not necessary that all components located in the base are included in the basic parametric construction. The components of the tool, which are not used in every tool, can be incorporated into the tool construction at the construction stage of the concrete tool.

Na področju orodjarstva obstajajo različne vrste računalniških programov, ki vsebujejo module z referenčnimi konstrukcijami vendar so namenjeni konstruiranju orodij za brizganje plastike. Delujejo sicer na podoben način, vendar se bistveno razlikujejo, saj jih ni mogoče uporabiti za konstruiranje orodij za preoblikovanje pločevine. Razlika je tudi v tem, da gre za modul, kije del računalniškega programa, v primeru mojega izuma pa gre za datoteko, ki je zgrajena tako, da omogoča parametrično določanje velikosti in oblik orodja in njegovih sestavnih delov.In the field of toolmaking, there are various types of computer programs that contain modules with reference structures but are designed to design tools for plastic injection molding. They function in a similar way, but differ significantly in that they cannot be used to construct sheet metal forming tools. The difference is that it is a module that is part of a computer program, and in the case of my invention, it is a file that is built to allow parametric determination of the size and shape of the tool and its components.

Izum je opisan v naslednjih odstavkih in slikah, ki predstavljajo:The invention is described in the following paragraphs and figures, which are:

FIG. 2 reference parametric tool construction designed to further construct cutting, trimming and punching tools with a progressive method of product manipulation

Gabariti orodja, tj. spodnji 1 in zgornji odlitek 2 so podani s parametri in so z relacijami povezani z konstrukcijo. Z spreminjanjem parametrov se spreminja velikost orodja. Na enak način je definirana tudi velikost in pozicija snemalne plošče 3.Tool dimensions, ie. the lower 1 and upper cast 2 are given by parameters and are related to the structure by relations. Changing the parameters changes the size of the tool. The size and position of the recording board 3 are defined in the same way.

Vodilna puša 4, prijemala zanjo 5, vodilni somik 6 in prijemala zanj 7 so dodani kot gradnik, saj so del baze parametrično določenih standardnih elementov. Njihova pozicija je definirana parametrično vendar jih lahko konstruktor s spremembo parametrov na zelo enostaven način prepozicionira in s tem optimizira razpoložljiv prostor v orodju. Njihovo velikost preprosto izbere iz tabele razpoložljivih standardiziranih možnosti, računalnik pa poskrbi za spremembo oblike in velikosti CAD modela vodilnih elementov.Guide sleeve 4, grips 5, guide strap 6 and grips 7 are added as a building block, as they form part of a base of parametrically defined standard elements. Their position is defined parametrically, but by changing the parameters, the constructor can reposition them in a very simple way, thus optimizing the available space in the tool. They simply select their size from the table of available standardized options, and the computer makes sure that the shape and size of the CAD model of the leading elements is changed.

Izvrtine za pritrditev vodilnih puš z prijemali 21 in izvrtine za pritrditev vodilnih somikov z prijemali 23 so z parametri v neposredni povezavi z pušami 4, prijemali 5, sorniki 6 in prijemali 7 ter se ob vsaki spremembi le teh spremenijo tudi dimenzije število in pozicija izvrtin 21 in 23.Bores for mounting guide bushings with grips 21 and bores for mounting guide bushings with grips 23 are directly related to bushings 4, grips 5, bolts 6 and grippers 7 with parameters, and the dimensions and number of holes 21 change with each change. and 23.

Distančniki orodja 8 so ravno tako gradnik in s tem del baze standardnih elementov. Na podlagi tabele razpoložljivih možnosti konstruktor izbere želeno obliko, (izbira lahko med okroglim in pravokotnim presekom) velikost in razporeditev v orodju. Ker so njihova pozicija v orodju, velikost in oblika podana parametrično se ustrezno spremeni CAD model.Tool 8 spacers are also a building block and therefore part of the standard element base. Based on the table of available options, the constructor selects the desired shape, (can choose between a circular and a rectangular cross-section) the size and arrangement in the tool. As their position in the tool, size and shape are given parametrically, the CAD model changes accordingly.

Na podlagi spremembe distancnikov orodja 8, se spremeni tudi pozicija, velikost in število lukenj za pritrditev distancnikov 22.By changing the tool spacers 8, the position, size and number of holes for fixing the spacers 22 are also changed.

Omejevalec hoda snemalne plošče 3, ki je sestavljen iz tulca 9, podložke 10, blažilne podložke 11 in vijaka 20 se obravnava skupaj kot prodprodukt njihovo pozicijo v orodju določimo z parametri, velikost pa izberemo iz tabele razpoložljivih standardnih možnosti. Uporabiti jih je možno ne samo kot omejevalo hoda, ampak tudi kot varovalo.The travel limiter of the record plate 3, which consists of a sleeve 9, washers 10, damping washers 11 and screws 20 is considered together as a product, their position in the tool is determined by parameters, and the size is selected from the table of available standard options. They can be used not only as a travel stop, but also as a safety device.

Navoji za pritrditev omejevala hoda 27 na zgornji odlitek 2 so z parametri usklajen z omejevalcem hoda (9 10 11 20) in se pozicija ter velikost lukenj 27 spreminjajo skladno s spremembo omejevala hoda (9 10 11 20). Ravno tako so luknje 26 v snemalni plošči 3 definirane na enak način, s tem da pri njih z vnosom parametra globine sprostitve podamo tudi hod snemalne plošče 3.The threads for attaching the stroke limiter 27 to the upper casting 2 are aligned with the stroke limiter (9 10 11 20) with parameters, and the position and size of the holes 27 change according to the variation of the stroke limiter (9 10 11 20). Likewise, the holes 26 in the recording board 3 are defined in the same way, by entering the travel of the recording board 3 by entering the release depth parameter.

Varovalni somik 12 za snemalno ploščo 3 in podložke 13 ki preprečuje izpadanje sornika 12, sta normirana in tudi del baze gradnikov. Velikost izberemo med razpoložljivimi v tabeli, pozicija pa je definirana parametrično. Uporabljati jih je možno tudi kot omejevalo hoda, in ne samo kot varovalni somik.The retainer 12 for the record plate 3 and the washers 13, which prevents the bolt 12 from falling, are standardized and also part of the base of the building blocks. The size is selected from the available tables, and the position is defined parametrically. They can also be used as a travel restraint, not just as a safety catfish.

Na somik 12 se navezujejo luknje 28 v zgornjem odlitku 2 in utor 24 na snemalni plošči 3. S kakršnokoli spremembo sornika 12 se ustrezno spremenijo tudi luknje 28 in utor 24, katerega dolžina je podana z dodatnim parametrom, ki določa njegovo dolžino in s tem hod snemalne plošče 3.Holes 12 are connected by holes 28 in the upper cast 2 and groove 24 on the recording plate 3. By any modification of the bolt 12, holes 28 and groove 24 are also changed accordingly, the length of which is given by an additional parameter determining its length and thus the stroke recording boards 3.

Plinske vzmeti 14, vpenjala za vzmeti 15 in tlačne ploščice 16 so obravnavani skupaj. Število, razporeditev v orodju, model in silo vzmeti poljubno izbiramo in s tem prilagajamo potrebam v orodju. Način vpenjanja vzmeti je možno izbirati med razpoložljivimi možnostmi iz tabele, ravno tako tudi tlačne ploščice. Izbirati je mogoče samo med tistimi, vpenjali za vzmeti 15 in tlačnimi ploščicami 16, ki so na voljo pri določenem modelu plinske vzmeti 14.Gas springs 14, springs for springs 15 and pressure plates 16 are considered together. The number, arrangement in the tool, the model and the force of the spring can be arbitrarily selected to fit the needs of the tool. The spring clamping method can be selected from the available options from the table, as well as the pressure plate. Only those springs 15 and the pressure plates 16 that are available with a particular gas spring model 14 can be selected.

Izvrtine za pritrditev vzmeti 29 na odlitku 2 se zaradi parametrične povezave z plinsko vzmetjo 14 in vpenjali za vzmeti 15 samodejno popravijo in njim prilagodijo obliko, razporeditev in velikost. Oblika razporeditev in velikost izvrtin za pritrditev tlačnih ploščic 25 na snemalni plošči 3 pa se prilagodijo tlačnim ploščicam 16Due to the parametric connection to the gas spring 14 and the spring clamps 15, the holes for fixing the springs 29 on the cast 2 are automatically corrected to adjust the shape, arrangement and size. The layout and size of the mounting holes for the pressure plate 25 on the recording plate 3 are adapted to the pressure plate 16

Dimenzije transportnih obešal 30 so normirane, in parametrično določene, izbiramo pa jih iz tabele razpoložljivih obešal, glede na težo orodja. Njihova postavitev je parametrično določena, lahko pa jih zaradi optimizacije prostora tudi prestavimo s pomočjo spremembo parametra njihove pozicije na orodju.The dimensions of the transport hangers 30 are standardized and parametrically determined and selected from the table of available hangers according to the weight of the tool. Their layout is parametrically determined, but in order to optimize space they can also be moved by changing the parameter of their position on the tool.

Vpenjalni nalitki z utorom ali luknjo 18 na spodnjem delu orodja 1 in vpenjalni nalitki z utorom ali luknjo 19 na zgornjem delu 2 so povsem neodvisni, saj se dogaja, da so spodnji utori na stiskalnici različni od zgornjih. Konstruktor z vnosom podatkov v obliki parametrov poda velikost, obliko, razporeditev in število nalitkov in izbere utor ali luknjo posebej za spodnji del in zgornji del orodja. S tem je možno prilagajati način vpenjanja na različnih stiskalnicah in tudi možnost privijanja na skupne plošče.The clamping inserts with groove or hole 18 on the lower part of tool 1 and the clamping inserts with groove or hole 19 on upper part 2 are completely independent, since the lower grooves on the press are different from the upper ones. The constructor, by entering parameter data, specifies the size, shape, arrangement, and number of fillings, and selects a groove or hole specifically for the bottom and top of the tool. In this way it is possible to adjust the clamping method on different presses as well as the possibility of screwing onto the common plates.

Distancniki orodja 108 so ravno tako gradnik in s tem del baze standardnih elementov. Na podlagi tabele razpoložljivih možnosti konstruktor izbere želeno obliko, (izbira lahko med okroglim in pravokotnim presekom) velikost in razporeditev v orodju.

Navoji za pritrditev omejevala hoda 133 na spodnji odlitek 101, in 127 na zgornji odlitek 102 so z parametri usklajen z omejevalcem hoda (109, 110, 111, 120) in se pozicija ter velikost lukenj 133 in 127 spreminjajo ločeno, skladno s spremembo omejevala hoda (109, 110, 111, 120). Ravno tako so luknje 126 v zgornjem pomičnem delu 103 in luknje 131 v držalu pločevine 104 definirane na enak način, s tem da pri njih z vnosom parametra globine sprostitve podamo tudi hod zgornjega pomičnega dela kakor tudi držala pločevine.The threads for fastening the stroke limiter 133 to the lower casting 101 and 127 to the upper casting 102 are aligned with the stroke limiter (109, 110, 111, 120) by parameters, and the position and size of the holes 133 and 127 are varied separately according to the variation of the stroke limiter (109, 110, 111, 120).

Enako velja za izvrtine za pritrditev plinskih vzmeti na 114 in tlačnih ploščic 116 na zgornjem delu orodja.The bores for the gas springs 134 on the cast 101 and 137 on the common plate 105 are automatically altered due to the parametric connection with the gas spring 114 and the clamps for the springs 115, adjusting their shape, arrangement and size.

It is also allowed to install gas springs 114 without common plates 105 or. 106.

Obdelave za pritrditev vzmeti 137, 138 kakor tudi obdelave za namestitev skupnih plošč 135,136 na odlitek se spreminjajo skladni z spremembo skupnih plošč 105,106.The treatments for mounting the springs 137, 138 as well as the treatments for mounting the common plates 135,136 per cast are varied according to the change in common plates 105,106.

Dimenzije transportnih obešal 203, 204 in somikov z 205 so normirane, in parametrično določene, izbiramo pa jih iz tabele razpoložljivih obešal, glede na težo orodja. Luknje za pritrditev obešal 208 so z relacijami povezane z obešali 203.The dimensions of transport hangers 203, 204 and catfish with 205 are standardized and parametrically determined, and are selected from the table of available hangers according to the weight of the tool. The mounting holes of the hangers 208 are related to the hangers 203 by the distances.

Obdelave za vpenjala 206 na spodnji plošči 200, 201 in obdelave 207 na zgornji 202 so povsem neodvisne, saj se dogaja, da so spodnji utori na stiskalnici različni od zgornjih. Konstruktor z vnosom podatkov v obliki parametrov poda velikost, obliko, razporeditev in število posebej za spodnji del in zgornji del orodja. S tem je možno prilagajati način vpenjanja na različnih stiskalnicah.The workpieces for the clamps 206 on the bottom plate 200, 201 and the workings 207 on the upper 202 are completely independent, since the lower grooves on the press are different from the upper ones. The constructor, by entering parameter data, specifies the size, shape, layout and number separately for the bottom and top of the tool. In this way, the clamping method of the various presses can be adjusted.
