Description

Изобретение относитс к строительству и предназначено дл использовани в установках дл сварки объемных арматурных каркасов железобетонных изделий.The invention relates to construction and is intended for use in installations for welding bulk reinforcing cages of reinforced concrete products.

Наиболее распространены установки с непрерывной спиральной навивкой поперечной арматуры на продольный каркас и поштучной выдачей плоской арматуры (хомутов ) под место сварки 1.Installations with continuous spiral winding of transverse reinforcement onto a longitudinal frame and single-piece delivery of flat reinforcement (clamps) for the welding area are the most common.

В установках с непрерывной навивкой арматуры можно достичь большой производительности ввиду непрерывности процесса, однако на них невозможно, как правило, сваривать арматуру большого диаметра из-за конструкции электродов, представл ющих собой ролики, которыми трудно создать необходимые давлени и токи сварки в отличие от плоских электродов, устанавливаемых на машинах с поштучной выдачей под место сварки плоских каркасов (хомутов); кроме того, непрерывна навивка предпочтительна дл круглых каркасов, в пр моугольных часто происходит потер геометрических форм из-за наличи остаточных деформаций в обв зочной проволоке.In plants with continuous winding of reinforcement it is possible to achieve high performance due to the continuity of the process, however, it is impossible to weld large diameter valves as a rule due to the design of electrodes, which are rollers, which make it difficult to create the necessary pressure and welding currents unlike flat electrodes. installed on machines with single delivery for the place of welding flat frames (clamps); In addition, continuous winding is preferable for round frames, and geometric forms are often lost in rectangular due to the presence of residual deformations in the binding wire.

Наиболее близким по технической суш,ности и достигаемому результату вл етс устройство дл сварки арматурных каркасов преимушественно пр моугольной формы с поперечными элементами в виде хомутов, содержащее сварочные электроды, механизм перемещени каркаса на шаг и механизм подачи поперечных элементов 2.The closest in technical sushi, ness and the achieved result is a device for welding reinforcing cages of predominantly rectangular shape with transverse elements in the form of clamps, containing welding electrodes, the mechanism for moving the frame per step and the feed mechanism for transverse elements 2.

Однако известные устройства не обеспечивают достаточно высокой производительности из-за необходимости подачи хомутов вручную..However, the known devices do not provide a sufficiently high performance due to the need to feed the clamps manually ..

Цель изобретени - повышение производительности путем автоматизации процесса подачи хомутов в зону сварки.The purpose of the invention is to increase productivity by automating the process of supplying clamps to the welding zone.

Дл этого механизм подачи поп еречных элементов выполнен в виде установленного вдоль линии подачи каркаса приводного вала с подпружиненным в осевом направлении диском, имеюшим винтовую наружную поверхность .For this purpose, the feed mechanism of the transverse elements is designed as a drive shaft frame installed along the feed line of the frame with an axially spring-loaded disk having a screw outer surface.

Claims

FIG. 1 shows the proposed device, side view; in fig. 2 - feed mechanism, side view; in fig. 3 - the same, top view; in fig. 4 - the same, rear view; in fig. 5 - section bb FIG. 2; FIG. 6 — node I in FIG. 2. In the device, welding is performed on a frame console having a faceplate 1 with stops 2, a welding head 3 moving around the frame. The piece-by-piece release mechanism of the clamps and the mechanism for moving the frame 4 are mounted on the frame of the device 5 in guides with the possibility of vertical movement with the screw -6. The pneumatic rod of the feed 7 of the frame to one pin has a brush 8 film with spring-loaded stops 9 which re-move the finished frame. On the shank 10 of the supply pneumatic cylinder stem 7, there is a collar 11, which rests on the films 12 lowered by the electromagnets 13 on the shank 10. The films are hingedly connected by the arms 14, 15 to the mechanism housing. The strips 12 are returned to their original position by the springs 16, which are adjusted by screw 17. The transverse reinforcement is delivered by the disk 18 located on the shaft 19. The disk is made with a screw outer surface and can be moved axially on the shaft 19 along the key 20. Contact a disc 18 with a perpendicular reinforcement 21 of a spring with a spring 22. The rotation of the disc 18 is carried out by a pneumatic cylinder 23, the brush of which is connected to a chain 24 spanning sprockets 25 and 26. The fixing of the rod 10 of the pneumatic cylinder from rotation produces 27. The rolling pins. The device operates as follows OM. ----- - - ----- After Lep Rivarki of the next clamp, the supply pneumatic cylinder 7 with spring stops, in contact with the welded clamp, moves the welded frame one step. Adjusting the pitch is made by lowering the electromagnets 13 of the strips 12 onto the shank 10 into which the collar I. abuts during the pneumatic cylinder. The piece delivery of the reinforcement is carried out by turning the disc 18 by one turn by means of a pneumatic cylinder 23 according to arrow A (see Fig. 6), and a thread turns one clamp from the others lying behind the bolt. In the reverse running of cylinder 23, the disc rotates in the direction of arrow B and takes the position shown in FIG. 6. When the frame is moved one step, the feed cylinder 7 yoke, located behind the disk, moves together with the longitudinal reinforcement, on which it lies before contact with the stops 2 on plate 1 and stops them under the welding point. The double stroke of the pneumatic cylinder 23 is carried out with the initial position of the pneumatic cylinder of the supply during the course of the welding ol & ykn around the frame during the welding process. The invention The device for welding reinforcing cages is predominantly rectangular in shape with transverse elements in the form of hm, containing welding electrodes, the mechanism for moving the frame per step and the mechanism for feeding transverse elements, characterized in that, in order to increase productivity by automating the process of feeding clamps the welding zone, the feed mechanism for the transverse elements are made in the form of a drive shaft frame installed along the feed line with a disk spring-loaded in the axial direction, having screw outer surface. .
