Abstract
Description
504 761 2 enligt uppfinningen undviks också en ensidig för kraftig töjning av det rörliga pressbordets stålband. 504 761 2 according to the invention also avoids a one-sided excessive strain of the movable press table steel strip.
En annan fördel är att en mot till exempel längden av en värmeplatta, dvs cirka 4 till 5 m, svarande grupp av dragstänger kan svängas ut åt sidan så att den berörda delen av pressen blir tillgänglig för underhållsarbeten, till exempel byte av en värmeplatta.Another advantage is that a group of tie rods corresponding to, for example, the length of a hot plate, ie about 4 to 5 m, can be swung out to the side so that the affected part of the press becomes available for maintenance work, for example replacing a hot plate.
Uppfinningen kommer nu att förklaras närmare med ledning av ritningen.The invention will now be explained in more detail with reference to the drawing.
Därvid visar fig 1 en schematisk vy av det rörliga pressbordet med driv- och ändtrummor i vy uppifrån, fig 2 det framifrån sedda snittet A-B i fig 4 med stålbanden utelämnade, fig 3 pressen enligt fig 2 med dragstänger utsvängda, och fig 4 en vy uppifrån av en del av pressen enligt fig 3.Fig. 1 shows a schematic view of the movable press table with drive and end drums in top view, Fig. 2 the front view AB in Fig. 4 with the steel strips left out, Fig. 3 the press according to Fig. 2 with drawbars flung out, and Fig. 4 a top view of a part of the press according to Fig. 3.
Den i fig 1 till 4 visade kontinuerliga pressen 1 består till sina huvuddelar av ett fast pressbord 2, ett rörligt pressbord 3 och längs sidorna anordnade press- ramstolpar 36. Pressborden 2, 3 består av enbart livplåtar och dessa förbindande tvärlister. Flera livplåtar med tvärlister är sammansvetsade till en balk 8, och flera balkar 8 med påsatta värmeplattor 14 bestämmer tillsammans pressbordens 2, 3, och därmed pressens 1 längd l. Från livplåtarna åt höger och vänster utstå- ende ansatser tjänar som stöd för pressramens stolpar 36 vid höjning och sänkning av det rörliga pressbordet. Presscylindrar med kort slag är därvid anordnade mellan de övre tvärstyckena 23 och det rörliga pressbordets 3 ansatser.The continuous press 1 shown in Figs. 1 to 4 consists in its main parts of a fixed press table 2, a movable press table 3 and press frame posts 36 arranged along the sides. The press tables 2, 3 consist only of life plates and these connecting cross strips. Several life plates with cross strips are welded together to form a beam 8, and several beams 8 with attached heating plates 14 together determine the length l of the press tables 2, and thus the press 1. The protrusions protruding from the life plates to the right and left serve to support the press frame posts 36. when raising and lowering the movable press table. Press cylinders with a short stroke are then arranged between the upper cross pieces 23 and the shoulders of the movable press table 3.
En stolpe 36 består av två dragstänger 13, ett övre tvärstycke 23 och ett undre tvärstycke 22. Tvärstyckena 22, 23 är försedda med åt höger och vänster utstående tappar eller bultar 26. Tvärstyckena förbinds med varandra genom att dragstängerna 13 hakas på på tapparna eller bultarna 26 med öglor 27.A post 36 consists of two tie rods 13, an upper crosspiece 23 and a lower crosspiece 22. The crosspieces 22, 23 are provided with right and left projecting pins or bolts 26. The crosspieces are connected to each other by hooking the tie rods 13 onto the pins or bolts 26 with loops 27.
Som framgår av fig 1 och 2 är det rörliga pressbordet 3 anordnat så att det med hjälp av förskjutningscylindrar 18 kan förskjutas eller vridas som en parallellogram kring vridaxeln 19 och den längsgående mittaxeln I-I. Vridningen av det rörliga pressbordet 3 begränsas av fyra anslag 38 vid en ram 20 med fasta pelare. Vid injusteringen av det rörliga pressbordets 3 längsgående mittaxel I-l till det fasta pressbordets 2 längsgående mittaxel med vinkeln d och 012 följer även presstolparna 36 med fritt rörliga dragstänger 13 med i rörelsgen med vinklar 81 eller 82. Med hjälp av denna parallellogramförskjutning av det rörliga pressbordet 3 kan även förloppet för det rörliga pressbordets 3 stålband 6 kring driv- och ändtrummornas axlar II-II och Ill-Ill justeras. En för stålbandet 6 särskilt skonsam behandling fås därvid genom att presstrycket i högtryckszonen HD, och vid särskilt högt presstryck även presstrycket i mellantryckszonen MD, tillfälligt avlastas.As can be seen from Figs. 1 and 2, the movable press table 3 is arranged so that it can be displaced or rotated by means of displacement cylinders 18 as a parallelogram around the axis of rotation 19 and the longitudinal central axis I-I. The rotation of the movable press table 3 is limited by four stops 38 at a frame 20 with fixed pillars. When adjusting the longitudinal center axis II of the movable press table 3 to the longitudinal center axis of the fixed press table 2 with the angle d and 012, the press posts 36 with freely movable drawbars 13 are also included in the movement gene with angles 81 or 82. the course of the steel strip 6 of the movable press table 3 around the axes II-II and III-Ill of the drive and end drums can also be adjusted. A treatment which is particularly gentle for the steel strip 6 is thereby obtained by temporarily relieving the press pressure in the high-pressure zone HD, and at particularly high press pressure also the press pressure in the intermediate pressure zone MD.
Med de tryck som används i dag behöver presstrycket i lågtryckszonen ND inte avlastas. De tre zonerna HD, MD och ND upptar i föreliggande fall vardera en tredjedel av pressens längd l. Sidoplåtar 21 är fast förbundna med det rörliga pressbordet 3 och används för att lagra drivtrumman 37, ändtrumman 10 ochWith the pressures used today, the press pressure in the low pressure zone ND does not need to be relieved. The three zones HD, MD and ND in the present case each occupy one third of the length 1 of the press. Side plates 21 are fixedly connected to the movable press table 3 and are used to store the drive drum 37, the end drum 10 and
