A kind of thread steel controlled cold rolling process

Abstract

The invention relates to the technical field of rebar processing, and discloses a controlled cold rolling process of rebar. The device used in the process includes a cooling box, a support rod, an air-drying platform and a blower. Both sides of the inner cavity of the cooling box are An electric telescopic rod 1 is fixedly connected, and the other end of the electric telescopic rod 1 is fixedly connected with the middle part of the support frame, and the other side of the support frame is movably connected with a rotating wheel, and all the rotating wheels are driven by a transmission belt. connected, the outer side of the drive belt is evenly and fixedly connected with a fixed table. In the rebar controlled cold rolling process, through the setting of the electric telescopic rod 1, the contraction of the electric telescopic rod 1 can change the distance between the two transmission belts, and the cooling box can cool steel pipes of different lengths, which improves the practicality of the cooling device. Property, through the setting of the electric telescopic rod two, the expansion and contraction of the electric telescopic rod two can make the fixing ring close and open, which is convenient for fixing and taking out of the steel pipe.

Description

technical field [0001] The invention relates to the technical field of screw steel processing, in particular to a controlled cold rolling process of screw steel. Background technique [0002] The cold rolling mill is a new type of cold rolling processing equipment for steel bars. This machine can process hot rolled wire rods and hot rolled coils with a diameter of 6.5 mm to 12 mm into cold rolled coils with a diameter of 5 mm to 12 mm. Ribbed steel bars, cold-rolled ribbed steel bars rolled by cold rolling mills are replacement products of cold-drawn low-carbon steel wires in prestressed concrete members, and can replace Class I steel bars in cast-in-place concrete structures. In order to save steel, it is a better kind of cold-processed steel of the same kind. If speed regulation is not required during the rolling process of the cold rolling mill, an AC motor can be used. If speed regulation is required during the rolling process of the cold rolling mill , a DC motor can b...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the existing controlled cold rolling process of rebar, the present invention provides a controlled cold rolling process of rebar, which has high cooling efficiency and uniform cooling of rebar, no mutual contact between rebars, and no contact between steel pipes. It will not cause damage due to mutual collision, and it is convenient for salvage and drying of steel pipes, etc., which solves the problems raised in the above-mentioned background technology
