Problems solved by technology

[0003] The existing rebar cold-rolling equipment mainly has the following technical problems in the use process: first, the temperature of the hot rebar is very high before entering the cold-rolling equipment, and the rebar under high temperature will directly contact with the components in the cold-rolling equipment. The internal parts of the cold-rolling device will be thermally damaged, resulting in a reduction in the service life of the cold-rolling device; in addition, the rebar has a large aspect ratio and a large weight. Therefore, the rebar is easy to bend during the cold pressing process, and the bent rebar will not only cause The rebar and the cold pressure roller cannot be aligned, and it will also cause unsmooth feeding

Abstract

The invention provides a high-strength deformed steel bar and a manufacturing method and device thereof, and relates to the technical field of deformed steel bars. The high-strength deformed steel bar manufacturing device comprises a base, a cold pressing roller, a cooling assembly, an aligning assembly and a deformed steel bar bearing assembly. According to the manufacturing device, the cooling assembly can cool the internal space of a cooling cover body, and the situation that parts in a cold rolling device are damaged due to the too high temperature of the deformed steel bar is avoided; by arranging a bearing rod and a bearing sleeve, a deformed steel bar section located in the cooling cover body can be supported; the deformed steel bar can be accurately fed into the cold rolling assembly from the cooling cover body by limiting the center line of the bearing sleeve, the center line of the cooling cover body and the center line of a deformed steel bar feeding opening to coincide, and the situation that cold rolling deviates or feeding is not smooth is avoided; the deformed steel bar bearing assembly is arranged at a deformed steel bar discharging port, so that the deformed steel bar output from the deformed steel bar discharging port can be supported; and the situation that cold rolling of the deformed steel bar is affected due to the fact that the deformed steel bar is bent under the gravity effect is avoided.

Description

technical field [0001] The invention belongs to the technical field of threaded steel bars, in particular to a high-strength threaded steel bar and its manufacturing method and manufacturing device. Background technique [0002] Rebar is an important building material. Rebar has the physical characteristics of high mechanical strength, long length, and good anchoring performance with concrete. Therefore, rebar and concrete can be used together and can be widely used in various types of buildings. Therefore, cold rolling of rebar can not only form indentations on the surface of rebar, improve its anchoring performance with concrete, but also reduce the internal stress of rebar, and effectively improve the mechanical properties of rebar. Therefore, cold rolling of rebar is an important part of the rebar preparation process. an important process. [0003] The existing rebar cold-rolling equipment mainly has the following technical problems in the use process: first, the temper...
