Problems solved by technology

Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. Steel bars can bear tension and increase mechanical strength. The connection of steel bars is very important in the field of civil construction, which is directly related to the strength of buildings. And durability, traditional connection methods include lap joint method and welding method. For special steel, the strength of the joint method and welding method has been difficult to meet the needs of current buildings.
The current ordinary thread processing machine tools use cutting to process threads, which weakens the strength of the threaded joints. In the on-site construction, the diameter tolerance zone of the steel bars is relatively large, which leads to the inability to guarantee the processing quality and seriously affects the on-site connection of the steel bars; moreover, the joint strength caused by cutting Weakened, greatly reducing the performance of the steel connection

Abstract

The invention discloses a straight thread rolling mechanical integrated machine, which comprises a rolling head, a steel bar clamping mechanism, a speed reducing motor, a feeding system, an electric control system and a cooling system, wherein the rolling head is axially linked with the speed reducing motor; the feeding system is arranged below the rolling head and the speed reducing motor and in fit transmission with the rolling head and the speed reducing motor; and the electric control system is arranged below the feeding system. The integrated machine has simple configuration, good using effect, strong maneuverability and high cost performance, and is suitable for large-area popularization and use in the engineering field.

Description

[0001] technical field [0002] The invention relates to a rolling device, in particular to a straight thread rolling machine integrated machine. Background technique [0003] In civil construction, rebar is steel for reinforced concrete and prestressed reinforced concrete, with a circular or sometimes square cross-section with rounded corners. Including plain round bars, ribbed bars, twisted bars. There are many types of steel bars, usually classified by chemical composition, production process, rolled shape, supply form, diameter, and use in structures. The steel bar for reinforced concrete refers to the straight or coiled steel used for reinforced concrete reinforcement, and its shape is divided into two types: smooth round steel bar and deformed steel bar. Steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, the deformed steel bar has a greater bonding capacity with the concrete, so it can better withstand the external force. Steel bars...
