Anti-torsion threaded steel roller assembly

Abstract

The invention provides an anti-torsion threaded steel roller assembly, and belongs to the field of rolling mills. The anti-torsion threaded steel roller assembly comprises a roller pair, a torsion detection device and a water tank, wherein the roller pair is fixed on a base; a fixing rack of one roller is provided with a rotating shaft and is further connected with the water tank through a push rod; the torsion detection device is arranged behind the roller pair and comprises two detection wheels which are clamped oppositely; semicircular grooves are formed in the detection wheels along the circumference; the pass and position formed after the two detection wheels are clamped oppositely are the same as those of the roller pair; a detection pull rod is hinged to the side surface of each detection wheel; the detection pull rods are connected with the water tank; the water tank is provided with a water inlet valve and a water outlet valve; the water inlet valve and the water outlet valveare connected through a connecting rod; the opening and closing directions of the water inlet valve and the water outlet valve are opposite through linkage of the connecting rod; the middle of the connecting rod is connected with the detection pull rods; a piston is further arranged inside the water tank; and the piston is connected with the push rod. According to the anti-torsion threaded steel roller assembly, a cooling water system of an original rolling mill is used as power, the angle of the roller is automatically adjusted, the parallelism is guaranteed, and the torsion of the threaded steel is prevented.

Description

technical field [0001] The invention belongs to the field of rolling mills, and in particular relates to a roll assembly which can independently prevent twisting during the rolling process of threaded steel. Background technique [0002] Rebar is a steel bar with transverse ribs and longitudinal ribs, which is rolled by a rolling mill. Qualified straight bars of rebar must meet the requirements of no torsional deformation. There are many factors that cause the twisting of rebar. Among them, during the rolling production process, the twisting that occurs when the rebar is rolled and formed through the finished hole of the roll is caused by the non-parallel rolling axes of the two opposite rolls, and according to the existing According to the research data, the torsion direction of the rebar is related to the offset direction of the axes of the two rolls, that is, when the upper roll is offset clockwise relative to the lower roll, the rebar is twisted in one direction, and whe...
