Application method of screw wire rod and reinforcement bar straightener

Abstract

The invention discloses a reinforcement bar straightener, comprising a stand as well as a multi-wheel straightening traction plate and a hydraulic cutting mechanism configured in sequence on the stand along the conveying direction of the reinforcement bar. The multi-wheel straightening traction plate is arranged at the front end of the stand, and the hydraulic cutting mechanism is arranged at the rear end of the stand and is opposite to the multi-wheel straightening traction plate. The straightener can meet the straightening requirement of large-size reinforcement bar, can realize low-consumption and rapid straightening and cutting and ensure high straightening stability. The invention also discloses an application method of a screw wire rod, which can improve the effective use ratio of the reinforcement bar, cancel invalid cutting in the steel plant and effectively solve the problem of transportation.

Description

technical field [0001] The invention relates to an application method of a large-scale steel bar wire rod, in particular to a threaded wire rod with a specification above Φ12mm. The invention also relates to a straightening machine suitable for threaded wire rods with specifications above Φ12mm. Background technique [0002] With the rapid development of my country's economic construction, the construction market presents an unprecedented gratifying scene. The demand for steel bars as an important material in construction projects has increased sharply, which has effectively stimulated the market demand for steel bar straightening and cutting machines. [0003] Steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is circular, sometimes square with rounded corners, mainly including round steel bar, threaded steel bar, twisted steel bar, etc., which can bear tensile force and increase mechanical strength.

Problems solved by technology

However, for steel bars with a diameter greater than 12 mm, due to the increase in cross-sectional size, they are almost bent in the same direction during coiling, and the stress direction is relatively easy to grasp. Only a single direction of pressure can be applied to effectively straighten, without the need for 360 At the same time, due to the increase of the radial dimension, the required traction and pressure will also increase exponentially. If the above-mentioned straightening machine is still used for straightening, since the straightening cylinder is 360-degree rotation adjustment, on the one hand it will It causes a waste of adjusting power, and a lot of useless work is done. On the other hand, the straightening cylinder will bear a huge reaction force, and its own structure is easily damaged, and it is very easy to cause locking.
