Abstract

The invention relates to a straightening rotary drum device for straightening steel bars, and belongs to metallurgic and building mechanical equipment. The straightening rotary drum device comprises a straightening rotary drum and a rotating hub support, wherein a back hat mounting hole is formed in the straightening rotary drum; a steel bar straightening structure with forwarding line which is a snake-shaped curve is arranged in the straightening rotary drum. The straightening rotary drum of the straightening rotary drum device is mounted on a straightening machine base; power is input through a belt and drives the straightening rotary drum to rotate; a steel bar enters from an inlet in the left side of the straightening rotary drum; under the action of traction force, the steel bar moves forwards along a curve through three straightening blocks which are arranged in a snake-shaped manner in the straightening rotary drum and is pulled out from an outlet in the right side, so that the steel bar is straightened by repeated straightening and pulling; in the process, under the action of pulling, the steel bar can be derusted, tempered and strengthened. When the straightening rotary drum works, the coiled type steel bar moves quickly in the straightening rotary drum after being uncoiled, so that continuous production can be realized, the production efficiency is high, and the straightening effect is good.

Description

Technical field: [0001] The invention involves a straight drum device, which is used for the straightness of steel bars and belongs to metallurgy and construction machinery. Background technique: [0002] The reinforced straight drum device is a coil -shaped reinforcement straight mechanical equipment.At present, the commonly used straight device is a pull -ups. This kind of facility has its limitations, which requires a large number of venues, and the reinforcement has a certain amount of stretching, which will reduce the strength of the reinforcement. Invention content [0003] The purpose of the present invention is to provide a rust that can remove the rust surface of the reinforcement at the same time in the process of straightening the reinforcement, and to adjust the reinforcement to the reinforced surface intensity to enhance the strength of the reinforced surface. [0004] Technical solution: [0005] The present invention includes: straight drums, rotating hub support...
