Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, and more particularly to a steel bar precision cutting and positioning device. Background Technology

[0002] The rebar straightening machine consists of a high-speed rotor that rotates to adjust the angle of the straightening die to achieve straightening. The wire is then fed forward by a wire feeding wheel. Once the required dimensions are reached, the wire hits the positioning key, which advances the track by 5 millimeters. The upper punch then presses down on the vertical cutting blade to cut the wire immediately. The wire is then pressed against the open bearing by the pressure plate on the vertical cutting blade, and the wire automatically falls to the wire support frame.

[0003] However, in actual use, after the steel bars are cut, steel mesh needs to be prepared. Each steel bar needs to be precisely positioned to make a steel mesh that meets the requirements. A single-position steel bar straightening machine cannot meet the positioning needs of steel bar processing. At the same time, it is necessary to manually or mechanically pull the steel bars to the appropriate processing position, which makes the cutting and positioning time long and the production efficiency low.
