The invention discloses a tempered tire bead wire straightening device. Two rows of bearing packs are distributed on each support (1), one row of bearing packs is movable bearing packs, and the other row of bearing packs is fixed bearing packs; the movable bearing packs and the fixed bearing packs are arranged oppositely, a gap (4) is formed between the movable bearing pack and the fixed bearing pack, a wiring slot I (5) is formed in the side surface of each movable bearing (2), a wiring slot II (6) is formed in the side surface of each fixed bearing (3), the wiring slot I (5) and the wiring slot II (6) are opposite, a steel wire (7) passes through the wiring slot I (5) of each movable bearing (2) and the wiring slot II (6) of each fixed bearing (3), a plurality of adjusting devices are arranged on the side surface of the support (1), each movable bearing (2) in the movable bearing pack is correspondingly provided with one adjusting device, each adjusting device is in transmission connection with the each movable bearing (2), and the position of the movable bearing (2) is adjusted by the adjusting device, so that the pressing amount of the steel wire (7) is adjusted.
Description
technical field [0001] The invention relates to a tempered bead steel wire straightening device and a straightening method. Background technique [0002] Linearity, one of the main indicators of the physical properties of the bead wire, is an important indicator for all tire factories to ensure normal production, and the bead wire in the drawing process will vary with the lubrication effect, wire diameter, three points and one line, etc. Changes, the straightness of the steel wire after drawing will also change in many ways, which cannot meet the needs of the tire factory. A straightener is added before the bead wire is taken up to ensure the straightness of the steel wire. The principle of the straightener utilizes the plasticity of the metal, and deforms the metal under the action of an external force with the help of a bearing, so as to obtain the required geometric shape and physical properties, and eliminate the stress of the steel wire. It is a pressure that changes th...
