Description

(54) Pružinové pridržiavacie zariadenie(54) Spring retaining device

Pružinové pridržiavacie zariadenie je určené na automatické plnenie paliet výstrižkami priamo na lise po operácii strihania. Spolehlivý chod zaisťujú ložiska držiaka opierajúce sa o vedenie pridržiavacieho zariadenia, pričom pri plnění palety posobia sila barana lisu a tiež výstrižkov prekonávajúce pasivné odpory a silu pružin. Pružinové pridržiavacie zariadenie sa upíná na príruby palety.The spring retaining device is designed to automatically fill pallets with blanks directly on the press after the shearing operation. Reliable operation is ensured by the bearings of the holder supported by the guide of the holding device, while during the filling of the pallet the forces of the press ram and the blanks overcoming the passive resistances and the force of the springs. The spring retaining device is clamped onto the pallet flanges.

Pružinové pridržiavacie zariadenie slúži na automatické plnenie paliet výstrlžkami priamo na lise v technologii plošného tvárné nia.The spring-loaded retaining device is used for automatic filling of pallets with dents directly on the press in the area of ductile nano technology.

Pri ručnej obsluhe lisov a na vytváranie medzioperačnej zásoby a přepravu výstrižkov, slúžia typizované palety, ktoré sa umiestňujú pod přepadový otvor v stole lisu, cez ktorý do nej z nástroja padajú výstřižky a ostávajú neorientované. Ďalší sposob odvodu výstrižkov z přepadového otvoru lisu je pomocou tzv. chobota, upevněného v spodnej časti nástroja, ktorý vedie orientované výlisky na odoberacie mieso, na ktorom obsluha plní přepravné palety orientovanými výstrižkami.For manual operation of the presses and for the creation of an in-process stock and the transport of cut-outs, standardized pallets are used which are placed under the overflow opening in the press table through which the cut-outs fall into the tool and remain undirected. Another way of removing blanks from the overflow opening of the press is by means of so-called. The trunk, fixed at the bottom of the tool, which directs the oriented moldings to the picking point, on which the operator fills the transport pallets with oriented cuttings.

V rámci automatizácie pracovísk plošného tvárnenia mění sa i technologický proces. Jednou zo zmien je vytváranie medzioperačnej zásoby výstrižkov pomocou rotačných zásobníkov prístrihov s paletami, v ktorých sú výlisky naukladané vo formě stohu. Palety sa v súčasnosti plnia výstrižkami ručně, čo je zdíhavé, namáhavé a mechanické.The technological process is also changing within the automation of sheet metal forming workplaces. One of the changes is the creation of an in-process stock of blanks using rotary stock bins with pallets in which the compacts are stacked. The pallets are currently filled with scraps by hand, which is strenuous, laborious and mechanical.

Vyššie uvedené sposoby vytvárania medzioperačnej zásoby výstrižkov nesplňujú podmienky automatizácie technologických pracovísk. Ručné plnenie paliet zásobníka prístrihov odstraňuje navrhované zariadenie, kde palety rotačného zásobníka prístrihov je možné plnit' priamo na lise. Na palete uchytenej pod přepadovým otvorom v stole lisu sa vytvára pomocou pružinového pridržiavacieho zariadenia pohyblivé dno slúžiace na plnenie palety. Po naplnění palety dochádza k zatlačeniu kontaktu spínača, ktorý vypíná Chod barana lisu a prevedie sa výměna palety za prázdnu.The aforementioned methods of creating an in-process stock of cuttings do not meet the conditions of automation of technological workplaces. Manual loading of the cutter magazine pallets removes the proposed device where the rotary cutter magazine pallets can be loaded directly on the press. On the pallet mounted under the overflow opening in the press table, a movable bottom is formed by means of a spring holding device for filling the pallet. When the pallet is filled, the contact of the switch is pushed, which switches off the run of the press ram and the pallet is replaced with empty one.

Výhodou plnenia paliet priamo na lise, riadenia, je odstránenie ručného sposobu ukladania výstrižkov do paliet a tým aj úspora pracovných sil. Činnosť obsluhy sa obmedzí na výměnu plných paliet za prázdné na zásobníku a výměnu paliet za plné na lise.The advantage of loading pallets directly on the press, steering, is the elimination of the manual way of placing the blanks in the pallets and thus saving labor. The operation of the operator is limited to replacing full pallets with empty pallets on the magazine and replacing pallets with full pallets on the press.

Na obrázku je zostava pružinového pridržiavacieho zariadenia, slúžiaceho na pridržiavanie stohu výstrižkov počas automatického· plnenia palety zásobníka prístrihov, upnutej v stole lisa. Pozostáva z vedenia 1, čo je dlhé vodiace puzdro tvaru štvorcovej rúrky, ktorá má na spodnom konci privarené dno 2. Vo vnútri rúrky sa pohybuje v rozsahu zdvihu držiak 3, ku ktorému sú skrutkami 4 připevněné telesa 5, slúžiace na uloženie čapov 6 ložísk 7, zabezpečujúcich spolahlivé vedenie držiaka 3 v· rozsahu krajných polůh. Vol’a medzi ložiskami 7 a vedením 1 je vymedzovaná nastavovacími skrutkami 23 s kontramaticami 24. Držiak 3 prenáša silu cez tlačná pružinu 8 na opierku 9 tvaru tenkostennej valcovej rúrky, pričom proti vysunutiu z puzdra je poistený krúžkom 25. V opierke 9 puzdra je skrutkami 10 připevněný priečnifc 11, na ktorý je zachytená tažná pružina 12, upevněná svojim horným koncom ku skrutke 13, ktorá je zaskrutkovaná do otvoru v uzávere 14. Uzávěr 14 sa nasúva na hornú časť vedenia 1, kde sa priskrutkuje skrutkami 15.Shown is a spring retainer assembly for retaining a stack of blanks during automatic loading of the cutter magazine pallet clamped in the press table. It consists of a guide 1, which is a long guide sleeve in the form of a square tube, which has a bottom welded at its lower end. Within the tube, a holder 3 is moved within the stroke range to which the bodies 5 are fastened. ensuring reliable guidance of the holder 3 in the range of extreme positions. The free space between the bearings 7 and the guide 1 is defined by the adjusting screws 23 with lock nuts 24. The holder 3 transmits the force through the compression spring 8 to the support 9 of the thin-walled cylindrical tube. 10 fastened by a transverse 11 to which a tension spring 12 is retained, fastened by its upper end to a screw 13 which is screwed into a hole in the closure 14. The closure 14 is slid onto the upper part of the guide 1 where it is screwed by screws 15.

Na spodnom konci vedenia 1 je privarené dno 2, na ktoré sa skrutkami 17 připevňuje koncový spínač 18 a zároveň sa naň upevňuje západka 19. Do západky 19 sa v dolnej polohe zachytí podložka 16, ktorá je připevněná k držiaku 3 pomocou upevňovacích elementov 20. Skrutka 21 poistená maticou 22 slúži ako doraz, ktorý v dolnej polohe stlačí kontakt spínača 18, čím dává signál, že paleta je naplněná výliskami.At the lower end of the conduit 1, a bottom 2 is welded to which a limit switch 18 is fastened with screws 17 and at the same time a latch 19 is attached thereto. The latch 19 engages a latch 16 in the lower position. 21 secured by the nut 22 serves as a stop which in the lower position presses the contact of the switch 18, giving a signal that the pallet is filled with moldings.

Vynález sa uplatňuje najma pri automatizovaných pracoviskách, ktoré využívajú rotačný zásobník prístrihov. V súčasnosti sa tieto pracoviska riešia stavebnicovým sposobom, čím sa rozšiřuje možnosť aplikácie v strojárskej praxi, najmá tam, kde je potřebné plnenie velkého· množstva tenkých plochých súčiastok menších rozmerov do· stohu.The invention applies in particular to automated workplaces which utilize a rotary magazine of blanks. Nowadays, these workplaces are solved in a modular way, which extends the possibility of application in engineering practice, especially where it is necessary to fill a large number of thin flat parts of smaller dimensions into a stack.
