Abstract

The invention relates to welding, in particular to the manufacture of steel girders with holes in the wall, which are widely used in various industries, mainly in the construction industry, including the construction of energy facilities. The purpose of the invention is to increase the efficiency of use of equipment by ensuring the manufacture of beams of different configurations on one process stream. The goal is achieved by cutting along the wall into the half shells of successive beams according to mirror curves, and one of the half shells of the first beam is withdrawn from the stream and joined with the remaining similar half sheave of the next beam. 3 il.

Description

The invention relates to welding, in particular to the manufacture of steel girders with holes in the wall, which are widely used in various industries, mainly in the construction industry, including the construction of energy facilities.

The purpose of the invention is to increase the efficiency of use of equipment.

Figure 1 shows the operations of the manufacturing process for the beams; figure 2 and 3 - section aa in figure 1 (manufactured beams).

For the manufacture of beams with holes in the wall on the production line, the operations of longitudinal cutting of the beam along a broken line into two half-shells, performed by device 1 (Fig. 1), assembly, carried out using roller tables 2, and welding, are performed. device 3.

To manufacture a Z-shaped beam with holes in the wall (Fig. 2), it is necessary for device 1 (Fig. 1, stage I) to cut the channel beam by longitudinal cut along the broken line, and to follow the channel beam following it in the flow - ()

slice along the broken line, mirrored

the previous one. Herewith, shelving orientation

of these two channel beams should be 3 different from one another, i.e., if the first channel beam was in the flow in shelves

up, then following it - shelves down.

Then using the roller conveyors 2 (figure 1,

stage ii) assembly by pro-tO

shallow shift of two semi-shafts, taken from

responsibly of the next two

other channel beams, different (J

the orientation of the shelves and the mirrored pro-k}

longitudinal cuts on the broken line. Wherein.

at the beginning of the work one of the half bars first

the channel beam in the flow is removed from the beam and then goes (at the end of the work) to an assembly with a semi-bar of the next (last) beam of a given beam size.

After assembling, the polubings go to the device 3 (Fig. 1, stage III), where they are welded into a beam with holes in the wall. ;

Similarly, an I-beam is made with holes in the wall (Fig. 3).

Claims (1)

Claims The method of manufacturing beams with holes in the wall is that the beams are cut into two half-beams along a curve having protrusions and depressions, joined along the protrusions and welding the protrusion joints, characterized in that the purpose of increasing the efficiency of equipment use by ensuring the manufacture of beams of different configurations on one process stream, cutting the wall on the semi-beams of the next one after the other beams is carried out according to mirror curves, and one of the semi-beams of the first beam is removed from the flow and joined to the remaining similar semi-weave of the next beam. | t
