Description

The invention relates to the production of equipment for resistance welding. A device for continuous welding is known, which comprises a support table placed on the frame, installed with the possibility of vertical movement, and a movable electrode with a recess for placing part 1. This device is not sufficiently high in performance, since the laying of the welded workpiece is carried out with a fixed electrode. The purpose of the invention is to increase the productivity of the device, which is achieved by the fact that it is equipped with rocker arms and connecting them with a thrust set on the supporting table and with a hinged four-link arm. The ha is equipped with a stop overlapping a recess in the electrode, and another stop is mounted on the frame to return the Hioca four-star to its original position. One of the crust villages is spring-loaded to the end of the support table. FIG. 1 image 1-) Apply a proposed device for contact relief welding, a general view; in fig. 2 is given a section along A-A in FIG. 1. The device contains an electrode 1, installed with the possibility of reciprocating PS. horizontal movement in the horizontal direction. In the electrode 1, a recess is made to place the part 2. The recess is blocked by an abutment 3 mounted on the rod 4, which together with the rocker arms 5, 6 and the support table 7, forms a hinged four-point bearing. The support table 7 is mounted with the possibility of vertical movement on the frame 8, on which the Part 9 is mounted. On the frame 8 a stop 10 is fixed to return the hinge cheater to its original position. A spring 11 is installed in the rocker arm, pressed by the screw 12 through the ball 13 to the end of the support table 7 (Fig. 2). The second electrode involved in the brewing process is the fixed electrode 14. The device operates as follows.

When the support foot 7 is moved to the upper position, it engages Part 9 and presses it against the electrode 14, and the stop 3 is placed in front of the electrode 1 and will block the groove in it, After that

Part 2 is fed into the recess. Part 2 can be supplied, for example, by a gate from the magazine (not shown on the drawings). Part 2 is supported in the recess by the stop 3 by means of the hinge

The new four-door is preloaded to the support station.

Lu 7 spring 11,

When the electrode 1 moves along with part 2, it moves the stop 3 and t 4, 4, Yokes 5 and B turn, carried by the slide -4. When parts 9 and 2 contact, welding is performed, after which electrode 1 is retracted to the initial position, the supporting table 7 is lowered, the product welded from parts 2 and 9 is laid on the frame .8, from where it is taken. The beam 5 interacts in the lower strut of the support table 7 with the abutment 1C) and rotates. the hinge joint with the support 3 returns to its original position.

Then, the support table 7 rises again to the upper position, the working cycle repeats.
