Между электродами размещен приемный лоток 11, закрепленный на станине и имеющий подпружиненные борта 12 для удержания поперечной сетки 13. Направляющие втулки 2 своими удаленными от электродов концами посредством шарниров 14 закреплены на станине с возможностью ограниченного поворота и снабжены роликами 15, каждый из которых контактирует с одним из поводков 10.The device consists of a bed 1, on which guide bushings 2 are fixed for guiding the longitudinal rods 3 of the reinforcing cage 4, drives 5 with upper electrodes 6 and lower electrodes 7, and a drive carriage 8 with intermediate electrodes 9 fixed on it and wedge-shaped leashes 10 is installed.

В процессе изготовления каркаса механизм сварки 16 сваривает плоскую попереч- 20 ную сетку 13, которая входит в приемный лоток И. После окончания сварки этой сетки каретку 8 перемещают в сторону электродов, в результате чего промежуточные электроды 9 войдут в сетку 13, а направляющие ₂₅втулки 2 вокруг шарниров 14 повернутся и прижмут продольные стержни 3 и сетки 13. Затем включают приводы 5 и посредством нижних и верхних электродов 7 и 6 приваривают стержни 3 к сетке 13. После оконча-. ния сварки каркас перемещают на шаг, ка4 ретку 8 отводят в исходное положение, и процесс повторяется.In the process of manufacturing the frame, the welding mechanism 16 welds a flat transverse 20 mesh 13, which is included in the receiving tray I. After welding of this mesh, the carriage 8 is moved towards the electrodes, as a result of which the intermediate electrodes 9 enter the mesh 13, and the guides _{25 of the} sleeve 2 around the hinges 14 they will turn and press the longitudinal rods 3 and grids 13. Then, the actuators 5 are turned on and the rods 3 are welded to the grid 13. by means of the lower and upper electrodes 7 and 6. welding, the frame is moved one step, the carriage 8 is returned to its original position, and the process is repeated.

Таким образом, предлагаемое устройст· во обеспечивает подачу поперечных сеток в положение, при котором их приваривают к 5 продольным стержням, что исключает операцию поворота каждой сетки перед сваркой, в результате чего повышается производительность.Thus, the proposed device · provides the supply of transverse grids in a position in which they are welded to 5 longitudinal rods, which eliminates the operation of turning each grid before welding, resulting in increased productivity.
