SU74160A1 - Device for electric arc welding under the flux layer of longitudinal seams of racks - Google Patents

Description

A disadvantage of the known devices for electric arc welding of longitudinal seams of struts is that it is impossible) to automate the welding process.

In the present device, this disadvantage is eliminated due to the use of a turntable equipped with workplaces for the installation of products, which provides automatic supply of products to the welding point.

On fi1 1 and 2 two projections of the proposed device are shown.

G-turn 1 g table At the device is designed; on single-mount fastening four welded products.

To clamp the parts to be welded, stops are arranged at the corners of the table .2, and in the center there is a fixed segment 3, which is cut by pneumatic clamp.

The welding head 4 is mounted on the frame 5 and can reciprocate under the action of the engine 6. Flux is supplied to the welding site from the hopper 7 by means of a worm gear; ortrsra 8. and the feed of the electrode wire from the coil 9.

All mechanisms of the welding device (pneumatic mechanism for clamping products, motor b of the welding head, motor 10 of the rotary table and source of welding current 11) operate automatically: at the same time, the table is rotated to the required angles. For this purpose, the axles 12 of the turntable are equipped with the corresponding cams, providing for cc.

The device operates as follows:

After installation of the blanks of the products to be welded into the corresponding cages of the stops 2 and segment 3, the motor 10 of the table is turned on and the axis 12 together with the table is turned into rotation.

When moving the table / floor 2, contact with the curvilinear paver of segment 3 and at the time of coincidence of the channels of the segment and the stops, the pneumatic clamps come into action. The pneumatic clamps are turned on by the cam 13. After the pneumatic clamps act under the cam 14, the cam 6 is switched on and the welding feed engine 101 | and a source of welding current. After the end of the welding process, the table 1 is rotated by 90 under the action of the cam 15. This starts the welding cycle.

The supply of new racks to the welding point is made after the table has been rotated for every 90. To facilitate the supply of gauging to the table of the machine, the conveyors or rollers 16 are pushed onto the table.
