Description

The invention relates to the field of mechanical engineering, in particular to the manufacture of welding equipment for welding longitudinal butt joints.

The known device containing a stationary cradle and beams, the keys of which are made in the form of levers set in motion from pneumo-tubing. These installations are inconvenient in operation because of the large well formed by beams and keys, which reduces the performance and quality of the weld, as it is difficult to review the welded joint.

Devices are known that contain a pressure beam with keys, guides the welding head and a movable lodgement 1 {21

However, these plants also do not provide a good overview of the welding zone, since their wells are relatively large.

The purpose of the invention is to improve the view when welding by reducing the cross section of the presser can without changing its fluid.

For this, in the proposed device, the pressure beam is equipped with a truss with

racks rigidly fixed on the cap, and the guides of the welding bar are installed on the truss.

FIG. 1 shows the device described, general view; in fig. 2 - section A-A of FIG. one.

The welding device consists of a frame 1 on which beams are mounted, made in the form of plates 2 and a rigid truss 3, which can be installed at a symmetrically welded joint or mixed from the front beam to conduct an overview from above behind the welding zone. The front lower part of the beam (possibly the rear lower part of the beam) is connected to the truss 3 by means of racks 4, transmitting the main force from the pozhement to the truss 3, protecting the lower part of the beam from deflection. To the lower plane of the plates 2, there are plate-shaped keys 5, iibieifmHe a groove, which ensures the movement of the Achavishi across the junction to establish the optimum gap between the keys.

Under the “2” is placed in the identity of t 6 with lining 7, wa xygodg g: yedbts8 welded iadelna 8, the lodgement nepevremaetsa vertically using two pneumoiyl (L {firewood 9, reversal of the lodgement relative to: the vertical axis carries her hand. but a guide 11 mounted on a truss 3, in the middle of which is placed an electrical equipment for controlling the welding process and an electric actuator 12, which drives the carriage 14, which fix the welding head 10 by means of a chain mechanism 13,. It begins by lowering the bed 6 with the help of pneumatic cylinders 9. and removing the pozhement to the side. The welded product 8 is put on the allotted ayohyent 6, and the bed 6 is returned under the tanks. With the help of pneumatic cylinders 9, the product 8 is pressed against the lamellar keys 5. 6 is perceived by the c-links 4 and transmitted by them to 3, excluding the deflection going 2, which provides a convenient overview of the welding zone, due to the shallow depth of the trimmer. Then, the welding and electric drive 12 of the chain mechanism 13, which drives the carriage 14 with the welding head Y, are turned on. After welding, the welded product 8 is removed from the lodgement in reverse order. Such a constructive solution of the device allows a well depth of no more than 40 mm with increased rigidity of the beams, which provides a convenient visual control of the weld zone.
