Description

The utility model relates to ferrous metallurgy, and more particularly to devices for the production of steel high-carbon profiled reinforcement used in the manufacture of reinforced concrete sleepers.

An urgent problem in organizing the production of modern components for the construction of railways is, in particular, the production of reinforced concrete sleepers (JBS) of the new generation. The production technology of new generation concrete reinforced concrete is aimed at a significant reduction in the metal consumption of structures, a reduction in labor intensity and energy costs due to the transition to enlarged reinforcement schemes.

At present, according to GOST 10629-88, reinforcing steel for the manufacture of concrete reinforced concrete is mainly used 44 mm high-carbon steel wire of a periodic profile with a diameter of 3 mm in class VR-2. in one sleeper. Such reinforcement in sleepers is very metal-intensive and a reduction in metal consumption in such a construction can be achieved by using reinforcement of large diameters (more than 8 mm) and its smaller number in reinforced concrete.

From RU 90719 U1, cl. B21C 1/00, publ. 01/20/2010, a device for manufacturing cold-rolled reinforcing bars of a periodic profile in coils is known, comprising an unwinding device, a descaling device, a lubrication device, a deformation unit made of roller dies, a multi-plane roller bending device, a pulling drum and a device for forming coils, the device the descaling unit additionally contains a section of rotating metal brushes, in front of the deforming block of roller dies on a monolithic die, a roller bending device consists of two groups of rollers placed in mutually perpendicular planes, while the axis of rotation of the group of rollers in front of the pulling drum is parallel to the axis of rotation of the pulling drum, and the device for forming coils consists of one or two rotating vertical figures with an external arched cylindrical contour located coaxially under the pulling drum.

The known device is characterized by the complexity of the design and does not provide the required parameters of the workpiece for profiled reinforcement of large diameters.

The closest solution to the claimed utility model in terms of technical nature and the achieved result is a device for the production of reinforcing profiles, known from RU 2040987 C1, cl. B21C 1/00, publ. 08/09/1995.

The device contains a monolithic die to obtain an oval-shaped profile and a profiling roller die, while it is equipped with a monolithic wire with a round gauge installed in front of the wire to receive 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 installed between the pair vertical rollers and profiling roller dragging with the rear end along the technological process of the end wall of the wiring from the axis of the rollers profile guide die at a predetermined distance.

A disadvantage of the known device is the need to supply the device with an additional drawing to obtain a blank for round-shaped reinforcement, and it is also significantly difficult to obtain profiled reinforcement of large diameters.

The technical result of the proposed utility model is to simplify the design of the device, reduce the metal consumption of reinforced concrete structures, as well as the possibility of obtaining steel high-carbon shaped reinforcement from a wire billet.

The technical result is achieved by the fact that the device for the production of steel profiled reinforcement from wire billets in coils or coils comprises a unit for preparing the wire billet for profiling and a unit for profiling the wire billet, while the unit for preparing the wire billet for profiling is made in the form of a straightening seven-roller device to provide anti-tension and centering a smooth cold-drawn wire billet, and the wire billet profiling unit is made in the form of non-driven roller cassette, in which rollers with a notch in the form of a reinforcement profile print are mounted, the rollers being located at an angle of 120 degrees relative to each other to obtain a triangular periodic profile on a cold-drawn wire billet.

A utility model is illustrated by a drawing, where its general view is shown.

The device consists of an unwinding unit 1 of a wire billet, a straightening device 2, rollers 3, a roller cassette 4 and profiling rollers 5 with a notch.

The device operates as follows.

A steel high-carbon smooth billet wire (not shown in Fig.) With a diameter of 10 mm from the unwinding unit 1 is fed to a leveling device 2, including 7 rollers, to prepare the billet wire for profiling, in which the wire is subjected to straightening (alternating bending), creating this counter-tension in front of the entrance to the roller cassette 4 and at the same time centering the axis of the wire when it enters the profiling rollers 5 of the roller cassette 4. In this case, the rollers 5, located at an angle of 120 degrees, leave three hundred an external profile imprint, creating a reinforcement with a diameter of 9.6 mm with a three-sided periodic profile. The wire from the roller cassette is pulled by any pulling device and then subjected to any type of processing, for example, such as hardening and cutting into bars of measured length.

The application of the proposed utility model reduces the metal consumption of reinforced concrete structures, as well as obtaining high-carbon steel profiled reinforcement of large diameters from a wire billet.
