Abstract

The invention relates to devices for assembling and welding beams of longitudinal and transverse elements used in welded metal structures. The aim of the invention is to increase productivity by reducing inter-operation time. The device contains a drive 5 longitudinal elements. (E) and the transverse E store. As a shop cutter of 8 transverse E, a strip 4 with slots for transverse E, located at a predetermined pitch, was used. With a longitudinal feed of the plank, transverse E are successively sunk into its sockets, which are then welded to the longitudinal E. 5 sludge. G color

The invention relates to welding, in particular to the construction of an apparatus for assembling and welding beams of longitudinal and transverse elements.

The aim of the invention is to increase productivity.

FIG. 1 shows the proposed device, type c6oKyJ in FIG. 2- node 1 in FIG. one; in fig. 3 is a section A-A in FIG. 1 in FIG. 4 is a section BB in FIG. one; in fig. 5 ..-- section BB in FIG. one.

The device has a base 1 along which the carriage 2 moves with the cradles 3 and the quick-change (on the pins) strip 4 with the slots.

At the beginning of the installation, an accumulator 5 for longitudinal elements 6 is located. The transverse elements 7 are stacked in a magazine 8 installed above the carriage 2. A spring-loaded clamp 9 is installed behind the magazine 8 for fixing the transverse elements 7 during welding. At the end of the device, there is a fixed spring-loaded puller 10 and a collector 11.

The drive of the reciprocating movement of the carriage 2 is carried out from the engine 12 through the chain transmission 13 and the pulley 14 by means of a flexible cable 15 covering the pulley 14 at a 360 ° angle and with its ends fixed at the extreme points of the carriage 2.

The device contains two welding heads 16, which are installed symmetrically one relative to the other.

The device works as follows.

When the carriage 2 is in the extreme right position, the longitudinal elements 6 are laid out of the accumulator 5 into the cradle 3, the drive is turned on and the carriage 2 starts moving. Clamp 9 | captures the intermediate; element 7 on the longitudinal elements 6.

At the approach of the intermediate element 7 to the welding heads 16

Dits welding simultaneously from two sides. After the last intermediate element 7 of the welded beam passes the spring-loaded puller

10, reverse carriage travel is activated. During the reverse course of the carriage 2, the puller 10 holds the beam in place for the last intermediate element 7 and it leaves the cradle 3, lying on the release device 11 and partially on the base 1.

During the return stroke, the front wall of the magazine 8 holds the intermediate elements 7 in the feeder. The carriage 2 returns to its original position and the cycle repeats. During the next cycle, the end face of the carriage 2, resting against the end face of the beam, pulls it onto the ejector 11. When the beam completely emerges onto the surface of the ejector 11, as high as a cylinder, it takes an unstable position and falls horizontally into the container. For

 switching to another beam size, it is enough to replace the bar 4, which is fixed on the base 1 on the pins.
