Description

one

There is a known method of rolling Shirokopolochny balokK, including prokapka billet in shaped gauges, hemming of flanges, turning and final rolling in a universal caliber.

1P, a new ionoco6, is distinguished by the fact that the rolling of the workpiece is carried out in a system of direct axial cross-shaped gauges.

This makes it possible to improve the size of the molding process and increase the durability of the rolls.

FIG. 1-8 shows the sequence of operations for burning rolling wide beam beams.

The square logging, skitowain by 45 °, is set in the left cross caliber, as shown in FIG. 1, and then the next cruciform caliber, depicted “and FIG. 2, in which flags are crimped, arranged perpendicularly to those rolled in the first caliber.

B (Two consecutive axisymmetric cross-shaped calibers (Fig. 3 and 4)

the process of rolling the billet is similar to n, rokatke in the first two calibers.

After deformation in the system of cross-shaped calibers, the flanges of the workpiece (Fig. 5) are bent in the I-beam profile, which 1 after turning - on 90 ° rolls in the system of calibers, shown in Fig. 6, 7, for the distillation of the cervical profile to the required size. The final rolling of the wide beam is carried out in a universal gauge (Fig. 8).

Subject invention

The method of rolling broadband balls, which includes rolling a billet in shaped calibers, hemming flanges, kaitovka and final rolling in a universal caliber, characterized in that, in order to improve the forming process and increase the durability of the rolls, the billet is rolled in a straight axisymmetric cruciform gauges.
