Description
7809707-8 den efter svetsningen, mellan konstruktionselementen kvar- stående spalten användes för utjämning av tillverknings- toleranserna qenom att konstruktionsdelarna sammanpressas, så att sagda sickar deformeras. The gap remaining after welding, between the structural elements, is used to equalize the manufacturing tolerances by compressing the structural parts, so that said seams are deformed.
Genom detta förfarande möjliggöres en väsentligt enklare, men samtidigt mera noggrann tillverkning _ av dylika konstruktionselement. Eftersom de olika plátdelarna är hopsvetsade med varandra endast på de deformerbara sickarna, uppstår en smal spalt mellan dem. Medelst kalibrerings- pressen pressas konstruktionselementet ihop tills sickarna deformerats under det höga trycket. Härvid erhåller konstruktionselementet den begärda noggrannheten. Sickarna är så beräknade, 'att den för deformeringen erforderliga kraften är större än de krafter, som under driften verkar på konstruktionselementet. För övrigt dimensioneras konstruktionselementet på sådant sätt, att en deformering endast kan ske på de deformerbara sickarna, när efter- präglingen till det från fall till fall begärda passnings- måttet utföres; i Beskrivning av ritningarna Som ett utföringsexempel för uppfinningen väljes en slid för armaturer, som i det följande kommer att beskrivas med hän- visning till de bifogade ritningarna.This method enables a considerably simpler, but at the same time more accurate manufacture of such construction elements. Since the different plate parts are welded together only on the deformable sickles, a narrow gap arises between them. By means of the calibration press, the construction element is compressed until the sags are deformed under the high pressure. In this case, the construction element obtains the required accuracy. The sills are calculated so that the force required for the deformation is greater than the forces which act on the structural element during operation. Incidentally, the structural element is dimensioned in such a way that a deformation can only take place on the deformable zigzags when the embossing of the fitting measure requested from case to case is carried out; Description of the drawings As an exemplary embodiment of the invention, a slide for luminaires is selected, which will be described in the following with reference to the accompanying drawings.
Figur l visar en kilslid, sedd framifrån, Figur 2 visar samma slid, sedd uppifrån, Figur 3 visar slíden från sidan, och Figur 4 visar i förstoring en enligt uppfinningen utförd sick.Figure 1 shows a wedge slide, seen from the front, Figure 2 shows the same slide, seen from above, Figure 3 shows the slide from the side, and Figure 4 shows on an enlarged scale a sickle made according to the invention.
Beskrivning av utföringsexempel Pâ figur 1 ser man plåttallrikar 2, som medelst punkt- svetsning är hopsvetsade med en bärram 1. Tallrikarna är skâlformiqt utförda, och de är inom den med 3 betecknade ytan medelst svetspunkter 4 förenade med bärramen 1, varvid 7809707-8, svetspunkterna 4 befinner sig inom området för en sick.Description of exemplary embodiments Figure 1 shows sheet metal plates 2 which are welded together by means of spot welding with a support frame 1. The plates are of shell-shaped design, and they are connected to the support frame 1 by means of welding points 4, wherein 7809707-8, the welding points 4 are in the area of a sickle.
Figur 2 visar ett hørisontalsnitt genom sliden. Den vänstra sektionshalvan tillhör en utförinqsform, där bärramen l består av två separata plattor 6, 7. Dessa är så hopsvetsade, att en U-formíg ränna 8 bildas vid ytterkanten.Figure 2 shows a horizontal section through the slide. The left half of the section belongs to an embodiment, where the support frame 1 consists of two separate plates 6, 7. These are so welded together that a U-shaped groove 8 is formed at the outer edge.
Den är avsedd att tjäna som styrning för sliden i ett hus, där det finns en skena 9, antydd på ritningen med prick- streckad linje. Den högra sektionshalvan i figur 2 visar en utförandeform, där bärramen 1 är utförd i ett stycke. Denna konstruktiøn används, när armaturhuset är försett med ett spår för styrning av sliden.It is intended to serve as a guide for the slide in a house, where there is a rail 9, indicated in the drawing with a dotted line. The right half of the section in figure 2 shows an embodiment, where the support frame 1 is made in one piece. This construction is used when the luminaire housing is provided with a groove for guiding the slide.
Figur 3 visar ett vertikalsnitt genom sliden. Mellan de båda plàttallríkarna 2 finns ett utrymme 10, avsett att bereda plats för slidens spindel.Figure 3 shows a vertical section through the slide. Between the two plate plates 2 there is a space 10, intended to make room for the spindle of the slide.
Figur 4 visar en i enlighet med uppfinningen framställd, på pláttallriken 2 eller bärramen l befintlig sick 11 med inpräglad svetsvårta 12, medelst vilken hopsvetsningen utförs. Med denna förbindelsemetod, antingen den sker på sickens eller över en på sicken anbragt svetsvårta 12, uppstår mellan de båda delar, som skall förbíndas med varandra, en smal spalt 13, vars bredd bestämmes av sickens höjd. Genom att i kalibreringspressen utöva det erforderliga trycket på sickarna, elimineras alla plåt- och tillverkningstoleranser, och den önskade slidvinkeln eller det erforderliga passningsmâttet erhålles genom en kompletterande prägling i en toleranspress. Sliden är därefter färdig att sättas in i huset.Figure 4 shows a zig 11 made with embossed weld wart 12, produced in accordance with the invention, on the plate plate 2 or the support frame 1, by means of which the welding is performed. With this connection method, whether it takes place on the sickle 12 or over a weld wart 12 arranged on the sickle, a narrow gap 13 arises between the two parts to be connected to each other, the width of which is determined by the height of the sickle. By exerting in the calibration press the required pressure on the zippers, all sheet metal and manufacturing tolerances are eliminated, and the desired wear angle or the required fitting measure is obtained by a complementary embossing in a tolerance press. The slide is then ready to be inserted into the housing.
