Abstract

FIELD: reinforcement bars production.

SUBSTANCE: invention relates to production of steel profiled reinforcement. Proposed device comprises monolithic drawing ring with round gage, drawing die to produce oval-shaped profile and profiling roller die. Possibility to produce profiled reinforcement with high carrying capacity is ensured by the fact that the device comprises monolithic drawing with ellipsoidal gage, installed after dolly for reception of oval-shaped profile, and profiling roller die consists of four rollers with notch in form of imprint of ellipsoidal reinforcement, located at different angles relative to each other, opposite large radius of ellipse – larger angle, opposite small radius of ellipse – smaller angle.

Description

The invention relates to ferrous metallurgy, and specifically to a device for the production of profiled steel reinforcement.

A device is known for the production of profiled steel reinforcement from wire billets, (Patent RU No. 110007) IPC В21С 1/00 (2006.01) Published: November 10, 2011 Bull. No. 31) containing a knot for preparing the wire billet for profiling and a knot for profiling the wire billet, to ensure anti-tension and centering of the unwound wire billet, the unit for preparing the wire billet for profiling is made in the form of a straightening seven-roller device, and the unit for profiling the wire billet is made in the form of a non-drive roller cassette.

However, the disadvantage of this device is, the resulting profiled reinforcement has a insufficiently high bearing capacity.

The closest device for the production of reinforcing profiles is known, (Patent RU No. 2040987 IPC В21С 1/00 (1995.01) Published: 08/09/1995) containing a die installed in a single production line for obtaining an oval-shaped profile and a profiling roller die, and it is equipped with a monolithic wire with round gauge installed in front of the wire to obtain an oval-shaped profile made in the form of a pair of vertical rollers with a smooth barrel and detachable wiring with a rectangular hole mounted between a pair of vertical x rollers and profiling roller drag.

The disadvantage of this device is, the resulting steel profiled reinforcement has a insufficiently high bearing capacity.

The technical result of the invention is to obtain a profiled reinforcement with high bearing capacity.

The technical result obtained by solving the problem is achieved in a device for the production of steel profiled reinforcement, including a monolithic die with a round gauge, a die for obtaining an oval-shaped profile, and a profiling roller die, the device containing a monolithic die with an ellipse gauge, after the die for obtaining an oval-shaped profile , and a profiling roller die of four rollers with a notch in the form of an imprint of the profile of an ellipsoid reinforcement located at different angles tnositelno each other, opposite the major radius of the ellipse greater angle opposite the small radius of the ellipse smaller angle.

Distinctive features are:

the device contains a monolithic die with an ellipse gauge, after the die to obtain an oval-shaped profile, which allows a small reduction sufficient to clarify the specified ellipse in the initial cold-rolled billet and create additional edits and centering of the billet before the profiling roller wire;

a profiling roller die of four rollers with a notch in the form of a profile imprint of an ellipsoidal reinforcement, this makes it possible to obtain profiled reinforcement with increased bearing capacity with a spatial arrangement of the long axis of the ellipse along the maximum load line in a reinforced concrete structure;

profiling roller die of four rollers located at different angles relative to each other, opposite a large ellipse radius, a larger angle, opposite a small ellipse radius, a smaller angle, this arrangement of rollers gives a better study of periodic profiles around the perimeter of the ellipse.

Comparison of the proposed solutions with analogues and prototype did not allow to identify in them the signs that distinguish the claimed solution, which allows us to conclude that the criterion of "novelty".

The use of ellipsoidal reinforcement improves the bearing quality of the reinforcement compared to round, due to a change in the geometric shape and its oriented location in the space of loads.

The described technological advantages allow to significantly expand the range of devices for the production of reinforcing profiles by increasing the bearing capacity.

The device operates as follows:

The pre-pointed end of the initial billet is passed through a round gauge detachable wiring hole, a die hole between smooth rollers, an ellipse gauge split wiring hole, a profiling hole, then the initial billet is pulled using a drawing device of a drawing mill. At the same time, a small reduction is performed in the monolithic die installed at the inlet, sufficient for straightening and aligning the workpiece in front of the vertical rollers and creates a counter-tension. When a round billet is deformed by vertical smooth rollers, a strip is formed - a flat oval, which passes a monolithic die with an ellipse caliber, where a small reduction is made, sufficient to straighten and center the workpiece in front of the forming rollers and creates a counter-tension. The resulting oval-shaped steel bar is subjected to processing on a profiling roller die in order to obtain an ellipsoid cylinder that is even along the entire length. On a roller cassette of four rollers with a notch in the form of an imprint of the profile of the ellipsoidal shape of the reinforcement, periodic profiles are applied with four-sided girth of the side surface of the ellipsoid cylinder. The location of the rollers relative to each other can be performed at an angle of 90 °. In order to better develop periodic profiles around the perimeter of the ellipse, the location of the rollers can be performed at different angles relative to each other, depending on the size of the radii of the ellipse.

Changes in the geometric shape of steel reinforcement can significantly expand the range of reinforcing ellipsoidal profile by increasing the bearing capacity.
