SU454949A1 - Two roll right caliber - Google Patents

Description

one

The invention relates to the processing of metal; under pressure.

Limes are a two-roll right gauge containing upper support and lower tension of the hunt.

For the quality of the driver, in the proposed caliber of the support roller, there is an odium-spaced distance from its tarcule-shaped ringed juice.

FIG. 1 low price proposed two-roll caliber; in fig. 2 is a diagram of straightening the end of the product section.

The proposed caliber is formed by pressure 1 and support 2 concave rolls. The latter is made of a central convex juice 3, in contact with the product 4.

Designed for durability, the flexoplastic bending is ensured by bending around the convex section 3 of the product 4 under the influence of the press a lot of rolls. Nodzhatimi lazy roller of product 4 to the convex over the onomore roll rolls the product at the site of its contact with the convex on the site. The area of the product in the deformation zone | 5. At the same time, the tensivity of the load variation of the loop 5 is piperbolic

with a bending moment close to pure izibib, the moment of which has a constant value for the billet, which ensures the elastoplastic deformation of all sections of the end section of the product to the end inclusive.

With such a deformation, the cryiasis and ovality are eliminated along the entire length, including the ends. At the same time, the thirst for editing the middle section of the section is improved.

To create the desired deformation zone, the pressure rollers are made with a concavity of a sufficiently small radius, and the back roll is made with a convexity of a sufficiently small

radius The end portion of the olor roll is connected to a transitional wave, which is convex along roller 1, of variable radius, chosen in such a way as to ensure the deflection of the straightened end of the product in combination with holding the product in the correct caliber.

The working profile of the concave press roll is chosen with a sufficiently long length in order to create the required number of sign-reversible alternating bends of the helix-displaceable along the helix required for high-quality editing.

The work roll of the support roller, convex to the ska, is given a length sufficient for

deformation straightened with rotation

tubes required number of alternating uiruglastic flattens.

Two-flush .right caliber containing top and bottom pressure

concave rolls, characterized in that, in order to improve the quality of the dressing, on the support roll, the arm is located at an equal distance from its ends, the convex annular band.
