H\u013abka<\/h3>\n\n

Prv\u00fdm rozdielom medzi bodov\u00fdmi a protikusov\u00fdmi otvormi je h\u013abka otvoru. Otvory s bodov\u00fdm povrchom nie s\u00fa hlbok\u00e9 a s\u00fa len nato\u013eko hlbok\u00e9, aby vytvorili rovn\u00fd povrch pre spojovac\u00ed materi\u00e1l. Najlep\u0161\u00edm postupom v tomto pr\u00edpade je neprid\u00e1va\u0165 \u010fal\u0161iu h\u013abku, ak je povrch s\u00fa\u010diastky rovn\u00fd a skrutka a s\u00fa\u010diastka s\u00fa na seba kolm\u00e9. T\u00e1to minim\u00e1lna h\u013abka je \u010dasto dostato\u010dn\u00e1 na to, aby boli spojovacie prvky zarovnan\u00e9 a spr\u00e1vne za\u0165a\u017een\u00e9.<\/p>\n\n

Otvory s protikusom s\u00fa hlb\u0161ie. S\u00fa ur\u010den\u00e9 na hlavy spojovac\u00edch prvkov, ktor\u00e9 vy\u010dnievaj\u00fa nad povrch obrobku. T\u00e1to h\u013abka zaru\u010duje, \u017ee hlava spojovacieho prvku nebude vy\u010dnieva\u0165. To je d\u00f4le\u017eit\u00e9 pri aplik\u00e1ci\u00e1ch, kde by sa odhalen\u00e1 hlava skrutky mohla zachyti\u0165 o in\u00e9 predmety. Alebo tam, kde sa povrch dielu mus\u00ed dot\u00fdka\u0165 in\u00e9ho dielu. Toto hlb\u0161ie zapustenie umo\u017e\u0148uje bezpe\u010dnej\u0161ie a atrakt\u00edvnej\u0161ie uchytenie.<\/p>\n\n

Funkcia<\/h3>\n\n

Bodov\u00e9 plochy sa pou\u017e\u00edvaj\u00fa na vytvorenie rovn\u00e9ho povrchu na nerovn\u00fdch obrobkoch, aby sa spojovacie prvky mohli r\u00fdchlej\u0161ie vyrovna\u0165 a nalo\u017ei\u0165. To je k\u013e\u00fa\u010dov\u00e9 pre diely vyroben\u00e9 odlievan\u00edm. M\u00f4\u017eu ma\u0165 drsn\u00fd, nerovn\u00fd povrch. Bodov\u00fd povrch pom\u00e1ha zabezpe\u010di\u0165, aby spojovacie prvky bezpe\u010dne spo\u010d\u00edvali na drsn\u00fdch povrchoch. T\u00fdmto sp\u00f4sobom vytv\u00e1raj\u00fa pevn\u00e9 spojenie.<\/p>\n\n

Protihroty sa pou\u017e\u00edvaj\u00fa na vytvorenie priestoru pre hlavy spojovac\u00edch prvkov, aby netr\u010dali von, \u010do m\u00f4\u017ee vies\u0165 k probl\u00e9mom pri mont\u00e1\u017ei. T\u00e1to kon\u0161trukcia je d\u00f4le\u017eit\u00e1 na pou\u017eitie tam, kde je potrebn\u00fd rovn\u00fd povrch na mont\u00e1\u017e mechanick\u00fdch dielov. Pou\u017e\u00edva sa aj tam, kde sa po\u017eaduje kozmetick\u00fd vzh\u013ead zapusten\u00e9ho spojovacieho prvku. M\u00e1 zapusten\u00fd otvor, ktor\u00fd mu dod\u00e1va n\u00edzky profil a zabezpe\u010duje, aby hlava spojovacieho prvku nepri\u0161la do kontaktu s in\u00fdmi dielmi.<\/p>\n\n

Tvar<\/h3>\n\n

Otvory s bodov\u00fdm povrchom a otvory s protikusom s\u00fa podobn\u00e9. Oba s\u00fa valcov\u00e9. Protihlavy s\u00fa v\u0161ak k\u00f3nick\u00e9 so \u0161ir\u0161\u00edm povrchov\u00fdm priemerom. Tento tvar umo\u017e\u0148uje skry\u0165 hlavu spojovacieho prvku v obrobku na rozdiel od bodov\u00fdch otvorov, ktor\u00fdch priemer je kon\u0161tantn\u00fd. Stup\u0148ovit\u00fd profil je u\u017eito\u010dn\u00fd najm\u00e4 vtedy, ke\u010f sa hlava spojovacieho prvku mus\u00ed usadi\u0165 do otvoru.<\/p>\n\n

Dno t\u00fdchto otvorov m\u00f4\u017ee by\u0165 ploch\u00e9 alebo ku\u017ee\u013eovit\u00e9 v z\u00e1vislosti od pou\u017eitej techniky v\u0155tania. Na vytvorenie otvoru s ploch\u00fdm dnom by sa mala pou\u017ei\u0165 technika v\u0155tania alebo n\u00e1stroj s nulov\u00fdm uhlom \u0161pi\u010dky. To pom\u00e1ha zabezpe\u010di\u0165, aby bol spojovac\u00ed prvok rovnomerne umiestnen\u00fd a aby pevne dr\u017eal na povrchu, ku ktor\u00e9mu sa prip\u00e1ja.<\/p>\n\n

Vyvol\u00e1vac\u00ed symbol<\/h3>\n\n

Symbol „\u2334“ predstavuje na technick\u00fdch v\u00fdkresoch protikus. Na v\u00e4\u010d\u0161ine v\u00fdkresov sa uv\u00e1dza jeho h\u013abka a priemer. To znamen\u00e1, \u017ee presn\u00e9 rozmery bud\u00fa efekt\u00edvne ozn\u00e1men\u00e9. Ide o symbol. Pou\u017e\u00edva sa na technick\u00fdch v\u00fdkresoch, aby strojn\u00edkom uk\u00e1zal presn\u00e9 \u0161pecifik\u00e1cie potrebn\u00e9 pre otvor s protikusom.<\/p>\n\n

Spotfaces pou\u017e\u00edvaj\u00fa podobn\u00fd symbol. M\u00e1 v sebe p\u00edsmen\u00e1 „SF“. Tieto p\u00edsmen\u00e1 predstavuj\u00fa ich \u0161pecifick\u00e9 potreby pod\u013ea normy ASME Y14. 5. Touto zmenou sa upravuje symbol protikusu pre bodov\u00e9 plochy. Zabra\u0148uje akejko\u013evek mo\u017enej nespr\u00e1vnej interpret\u00e1cii pokynov na obr\u00e1banie v\u00fdrobku.<\/p>\n\n

Ve\u013ekos\u0165<\/h3>\n\n

Rozmery otvorov s bodovou plochou sa zvy\u010dajne ur\u010duj\u00fa priemerom otvoru alebo dutiny pre spojovac\u00ed prvok. Nie je hlbok\u00fd, aby sa mohol z\u00edska\u0165 hladk\u00fd povrch pre hlavu spojovacieho prvku. T\u00e1to \u0161pecifik\u00e1cia rozmerov stanovuje h\u013abku bodov\u00e9ho povrchu. Je to tak akur\u00e1t pre jeho funkciu a zabra\u0148uje odstr\u00e1neniu pr\u00edli\u0161 ve\u013ek\u00e9ho mno\u017estva materi\u00e1lu.<\/p>\n\n

Priemer a h\u013abka ur\u010duj\u00fa ve\u013ekos\u0165 otvoru pre protikus. Priemer zodpoved\u00e1 ve\u013ekosti hlavy spojovacieho prvku; h\u013abka ur\u010duje, ako hlboko bude spojovac\u00ed prvok zapusten\u00fd pod povrch. Je to spravidla hlb\u0161ie ako bodov\u00fd povrch. Ve\u013ekos\u0165 protikusov by sa mala pri protikusov\u00fdch otvoroch bra\u0165 presne, preto\u017ee to pom\u00f4\u017ee pri spr\u00e1vnom zapusten\u00ed hlavy spojovacieho prvku.<\/p>\n\n

Povrchov\u00e1 \u00faprava<\/h3>\n\n

Posledn\u00fdm sp\u00f4sobom, ktor\u00fdm sa l\u00ed\u0161ia otvory s bodov\u00fdm povrchom a otvory s proti\u013eahl\u00fdm v\u00fdvrtom, je povrchov\u00e1 \u00faprava. Bodov\u00e9 povrchy s\u00fa zvy\u010dajne hlad\u0161ie, preto\u017ee s\u00fa prim\u00e1rne ur\u010den\u00e9 ako rovn\u00fd povrch na osadenie spojovacieho prvku. T\u00fdm sa dosiahne spr\u00e1vna up\u00ednacia sila a spr\u00e1vne zarovnanie dielov, \u010do je ve\u013emi d\u00f4le\u017eit\u00e9 na zabezpe\u010denie toho, aby sa zostava nepo\u0161kodila.<\/p>\n\n

Bo\u010dn\u00e9 steny protikusov nemusia by\u0165 tak hladk\u00e9 ako pri in\u00fdch otvoroch, preto\u017ee hlavn\u00fdm \u00fa\u010delom tohto typu otvoru je vytvori\u0165 priehlbinu pre hlavu spojovacieho prvku. Povrchov\u00e1 \u00faprava protiv\u00fdvrtov nemus\u00ed by\u0165 tak\u00e1 hladk\u00e1 ako protih\u013abenia. Je v\u0161ak nevyhnutn\u00e9, aby sa do nich zmestila a udr\u017eala hlava spojovacieho prvku.<\/p>\n\n

Aplik\u00e1cie<\/h3>\n\n

Bodov\u00e9 plochy vytv\u00e1raj\u00fa rovn\u00fd povrch na osadenie nepravideln\u00e9ho alebo zakriven\u00e9ho obrobku. S\u00fa be\u017en\u00e9 pri odliatkoch. Pom\u00e1haj\u00fa umiestni\u0165 spojovacie prvky na spr\u00e1vne miesto a zabezpe\u010duj\u00fa ich bezpe\u010dn\u00e9 ulo\u017eenie na nerovnom povrchu. Bodov\u00e9 plochy sa pou\u017e\u00edvaj\u00fa aj v lo\u017eisk\u00e1ch, aby sa zabezpe\u010dilo ich presn\u00e9 rovn\u00e9 ulo\u017eenie na zn\u00ed\u017eenie trenia a zabezpe\u010denie s\u00faososti.<\/p>\n\n

Protihlavy sa dobre hodia pre zostavy, v ktor\u00fdch sa musia hlavy spojovac\u00edch prvkov zah\u013abi\u0165 kv\u00f4li vzh\u013eadu. To je be\u017en\u00e9 pri obr\u00e1ban\u00ed kovov a dreva. Je to obzvl\u00e1\u0161\u0165 u\u017eito\u010dn\u00e9 pri prevencii zasek\u00e1vania o bl\u00edzke predmety. Na in\u0161tal\u00e1ciu dielov s\u00fa potrebn\u00e9 rovn\u00e9 povrchy. Protihroty sa \u010dasto pou\u017e\u00edvaj\u00fa na zakrytie hl\u00e1v skrutiek alebo skrutiek, \u010d\u00edm sa dosiahne \u00fah\u013eadn\u00fd a profesion\u00e1lny povrch.<\/p>\n\n

V porovnan\u00ed s CNC fr\u00e9zovan\u00edm v\u0161ak m\u00f4\u017ee vykazova\u0165 ni\u017e\u0161iu r\u00fdchlos\u0165 v\u00fdroby a zn\u00ed\u017een\u00fa presnos\u0165.<\/p>\n\n

CNC fr\u00e9zovanie<\/h3>\n\n

Fr\u00e9zovanie CNC je in\u00e9. Je to po\u010d\u00edta\u010dom riaden\u00fd proces obr\u00e1bania. Je zn\u00e1my svojou presnos\u0165ou a efekt\u00edvnos\u0165ou. Stroj pou\u017e\u00edva rezn\u00e9 n\u00e1stroje na presn\u00e9 odstra\u0148ovanie materi\u00e1lu z obrobku na vytvorenie zlo\u017eit\u00fdch tvarov. Tvary maj\u00fa toleranciu a\u017e 0,0004 palca. Tento automatizovan\u00fd proces je vynikaj\u00faci pri v\u00fdrobe profilov, dut\u00edn a kont\u00far povrchu. Stoj\u00ed viac a vy\u017eaduje si \u0161peci\u00e1lne \u0161kolenie. Fr\u00e9zovanie CNC je v\u0161ak presnej\u0161ie, r\u00fdchlej\u0161ie a poskytuje lep\u0161ie povrchov\u00e9 \u00fapravy ako ru\u010dn\u00e9 fr\u00e9zovanie.<\/p>\n\n

Pri zva\u017eovan\u00ed bodov\u00fdch pl\u00f4ch a protikusov maj\u00fa ru\u010dn\u00e9 aj CNC fr\u00e9zovanie svoje v\u00fdhody a nev\u00fdhody. Ru\u010dn\u00e9 fr\u00e9zovanie je n\u00e1kladovo efekt\u00edvne a jednoduch\u00e9. Fr\u00e9zovanie CNC v\u0161ak zaru\u010duje bezkonkuren\u010dn\u00fa presnos\u0165 a efekt\u00edvnos\u0165. V\u00fdber medzi t\u00fdmito dvoma sp\u00f4sobmi z\u00e1vis\u00ed od faktorov. Medzi ne patr\u00ed objem v\u00fdroby, rozpo\u010dtov\u00e9 limity a potrebn\u00e1 presnos\u0165.<\/p>\n\n

Ako sa dimenzuj\u00fa bodov\u00e9 plochy a protihroty?<\/h2>\n\n

Dimenzovanie bodov\u00fdch pl\u00f4ch<\/h3>\n\n

Dimenzovanie bodov\u00fdch pl\u00f4ch zah\u0155\u0148a ur\u010denie ich priemeru a h\u013abky. Priemer zodpoved\u00e1 ploch\u00e9mu, hladk\u00e9mu povrchu, ktor\u00fd sa dot\u00fdka podlo\u017eky, matice alebo hlavy skrutky. H\u013abka je zvy\u010dajne pribli\u017ene 0,0625 palca. Zabezpe\u010denie presn\u00e9ho priemeru je ve\u013emi d\u00f4le\u017eit\u00e9. Vytv\u00e1ra presne umiestnen\u00fd povrch. To umo\u017e\u0148uje bezpe\u010dn\u00e9 spojenie medzi spojovac\u00edm prvkom a obrobkom.<\/p>\n\n

Dimenzovanie protikusov<\/h3>\n\n

Dimenzovanie protikusu zah\u0155\u0148a uvedenie jeho priemeru a h\u013abky. Niekedy je potrebn\u00e9 uvies\u0165 aj priemer pilotn\u00e9ho otvoru. Priemer protikusu mus\u00ed by\u0165 dostato\u010dne ve\u013ek\u00fd pre hlavu spojovacieho prvku. H\u013abka zabezpe\u010duje, aby hlava sedela v jednej rovine alebo pod obrobkom. Presn\u00e9 dimenzovanie zabezpe\u010d\u00ed, \u017ee protiv\u00fdvrt bude ma\u0165 potrebn\u00e9 zah\u013abenie. V\u00fdsledkom je bezpe\u010dn\u00e9 a presn\u00e9 spojenie.<\/p>\n\n

Z\u00e1ver<\/h2>\n\n

Bodov\u00e9 a protiv\u0155tacie profily s\u00fa v presnom stroj\u00e1rstve nepostr\u00e1date\u013en\u00e9 a pon\u00fakaj\u00fa rie\u0161enia pre r\u00f4zne potreby obr\u00e1bania. \u010ci u\u017e ide o vytv\u00e1ranie rovn\u00fdch pl\u00f4ch pre spojovacie prvky alebo vyh\u013aben\u00ed pre vy\u010dnievaj\u00face hlavy, tieto prvky zlep\u0161uj\u00fa funk\u010dnos\u0165 aj estetiku mechanick\u00fdch zost\u00e1v.<\/p>\n\n

Presk\u00famajte na\u0161e slu\u017eby presn\u00e9ho obr\u00e1bania, aby ste vyu\u017eili v\u00fdhody bodov\u00fdch a protihrotov\u00fdch rezov pre svoje technick\u00e9 projekty. Vytvorme spolu presn\u00e9 rie\u0161enia.<\/p>\n","protected":false},"excerpt":{"rendered":"
