Abstract

Mechanizmus na navolenie razníkov v raziacej hlavě. Účelom vynálezu je umožnenie rubovolné- ho zoskupenia razníkov v raziacej hlavě. Uvedeného účelu sa dosiahne mechanizmom na navolenie a aretáciu razníkov raziacej hlavě, ktorý má v telese 1, opatrenompriechodzím otvorom pre razník 2 vytvořené štvorcové drážky, kolmé na os razníka 2, s uloženými posuvnými západkami 3 uzatvorenými vekom 6 pomocou vodorovných pružin 7 pre držanie razníka 2 vo vysunutej polohe za osadenie 16 a lišty4 uložené vo veku 6, opatřené kladkami 20 sú v styku cez kolíky 5 s posuvnými západkami 3, pričom razník 2, opatřený v hornej časti zvislou pružinou 9, je v styku prostredníctvom páky 11 s ovládacím zariadením.Mechanism for selecting punches in a punching head. The purpose of the invention is to enable a free-form grouping of punches in a punching head. The stated purpose is achieved by a mechanism for selecting and locking punches in a punching head, which has square grooves formed in the body 1, provided with a through hole for the punch 2, perpendicular to the axis of the punch 2, with mounted sliding latches 3 closed by a lid 6 by means of horizontal springs 7 for holding the punch 2 in the extended position behind the shoulder 16 and the strips 4 mounted in the lid 6, provided with rollers 20 are in contact via pins 5 with the sliding latches 3, while the punch 2, provided in the upper part with a vertical spring 9, is in contact via a lever 11 with the control device.

Description

Vynález sa týká mechanizmu na navolenie a aretáciu razníkov v raziacej hlavě s možnosťou ich rubovólného zoskupenia.BACKGROUND OF THE INVENTION The present invention relates to a mechanism for selecting and arresting punches in an embossing head with the possibility of their reverse arrangement.

Do diemych štítkov z papierovej lepenky o hrúbke 1 mm sa vystrihujú otvory priemeru 6 mm v róznom zoskupení — kóde — v jednom riadku ; najviac 6 otvorov. Počet riadkov v štítku najviac , 20. Otvory sa vysekávali v přípravku, kde sa ručně natočením kódového valčeka s kolíkmi uloženého i na páke předvolili potřebné razníky zodpovedajú- j : ce danému kódu. Cez páku sa pod ručným lisom | i pomocou kódového valčeka pósobilo na potřebné razníky a do kódového štítku sa vystřihli otvory. |6 mm diameter holes are cut into the diode labels of paperboard with a thickness of 1 mm in a rows - code - in one line; up to 6 holes. The number of lines in the label at most, 20. Holes were punched in the jig where the necessary punches corresponding to the code were preselected by manually rotating the code roller with both the pin and the pin. Over the lever under the hand press | even with the code roller, it applied to the necessary punches and holes were cut into the code plate. |

Tento pracovný spósob odstraňuje mechanická, ' raziaca hlava podťa vynálezu, ktorého podstata í spočívá v tom, že v telese hlavy zoskrutkovanej zo ‘ štyroch častí sú uložené razníky s osadením a mož-7 nosťou zvislého posuvu. Razník, ktorý sa má vysunúť do funkčnej polohy přetlačí dvojicu zápa- diek, ktoré po dosiahnutí polohy razníka zaskočením za osadenie držia tento vo vysunutej polohe. i Po vykonaní pracovného zdvihu celej hlavy z východzej polohy smerom dole prebehne hlava ! východzou polohou smerom hoře kde sa naběhnutím líšt na klínové narážky roztiahnu západky a navolený razník sa pomocou pružiny vrátí do póvodnej polohy. Příklad konštrukčného riešenia je znázorněný na připojených výkresoch, kde obr. 1 představuje rez mechanizmom v rovině zavesenia, obr. 2 ťavý pohíad, obr. 3 bočný pohfad na klínové narážky a kladky z obr. 2.This operating method eliminates the mechanical punching head of the invention, which is characterized in that punched and pusher-mounted punches are provided in the head body screwed from the four parts. The punch to be moved into the functional position overrides the pair of pins which, when the punch position is reached by snapping it into place, hold it in the extended position. i After the entire stroke of the entire head is taken from the starting position downwards, the head runs! a starting position in the direction of the mountain, where the latches expand by latching the wedges into the wedge stops, and the dial selected by the spring returns to the lower position. An exemplary embodiment is shown in the accompanying drawings, in which: Figure 1 is a cross-sectional view of the mechanism in the suspension plane; Figure 2 is a cross-sectional view; Figure 3 is a side view of the wedge stops and pulleys of Figure 2.

Teleso 1 má v pozdlžnej osi šesť vodiacich otvorov, ktoré sú z hornej strany zvačšené do takejThe body 1 has six guide holes in the longitudinal axis, which are topped to such an extent.

Claims

Mechanism for selecting and locking punches: in the punching head with the possibility of their arbitrary grouping, characterized in that in the body (1) provided with a through hole for the punch (2), square grooves are formed, perpendicular to the axis of the punch (2), in which the sliding pawls (3) are closed by a lid (6) by means of horizontal strips to accommodate the shoulder 16 of punches 2. Perpendicularly to these holes are formed square cross-section grooves in which the sliding pawls 3 are pressed into center by means of horizontal springs 7 from the opposite thatch

8. In each latch 3, a pin 5 is pressed into the groove in the upper body 6, which is screwed to the body 1 by screws 19, at the same time closing the square grooves for the latches 3. 6, a cylindrical portion on which are mounted ball bearings 20 acting as pulleys. On the upper body 6, the ridge 17 and the hinge 10 are bolted by means of screws 21, which in the upper part are terminated by a hanging ear 22 in which the opening 23 is connected by means of which the head is connected to the lever mechanism by which it is operated by cam. In the ridge 17, levers 11 are mounted on the axle 12. Pressure is applied to the upper part 13 of the lever 11 by means of a Bowden 15, which is transmitted to the punch 2 by the lower end 14 with a rounded end and pushed into the working position against the vertical spring 9. After performing the necessary stroke of the pawl 3, the pawl 2 engages behind the shoulder 16 of the punch 2 and holds it in the extended position. After transfer of the working stroke in reverse movement, the head with the cam runs through the starting position upwards, the ball bearings 20 on the rails 4 approach the adjustable wedges 18. The rails 4 thus move away from the punches 2 by means of pins 5 of the latch 3. and these are returned to the starting position by means of vertical springs 9.

OF THE INVENTION for holding a punch (2) in an extended position behind a shoulder (16), the rails (7), wherein the slats (4) housed in the lid (6) provided with ball bearings (20) are in contact through the pins (5) with the pawls (3), while the punch (2) provided with a vertical spring (9) in the upper part is in contact with the control device by means of the lever (11).
