Description

TECHNICAL FIELD

[0001] The utility model relates to straightener technical field especially relates to a steel wire straightener and straightener group. BACKGROUND

[0002] The wire rod processing industry generally has some requirements on the straightness of steel wire, and the common practice is to physically straighten the steel wire by using a straightener to meet the straightness requirements. For example, in the bead wire industry, the raw material wire rod needs to be processed through multiple drawing processes to change its diameter, and the plastic drawing of the wire rod changes the original structure of the wire rod, causing the drawn steel wire to have stresses in different directions and of different sizes. Due to the uneven internal stress of the steel wire, the straightness of the steel wire is also randomly curved and unstable in the natural state, which is extremely detrimental to the wire laying, coiling, unwinding, and subsequent copper plating processes. To solve the problem of uneven internal stress of the steel wire, the industry uses two straighteners arranged horizontally and vertically to form a straightener group to straighten the steel wire in terms of diameter and vector direction.

[0003] The straightener currently in use is to pass the steel wire through two rows of grooved bearings, and then press the movable bearings against the steel wire to move closer to the stationary bearings by tightening the bolts. The straightness of the steel wire in this direction is changed by rotating the bolts to control the amount of bearing pressing. Although this adjustment method is simple, it still has the following problems: 1. The operator directly adjusts the bolts, and as the pressing amount increases, it becomes more and more difficult to rotate the bolts, and tools must be used when necessary, making the adjustment operation inconvenient; 2. The bearing pressing amount is related to the thread pitch of the bolt, and rotating the bolt by one pitch will cause the bearing to press in or out by one pitch, which cannot be adjusted by a small amount, thereby affecting the operator's adjustment time and production efficiency; 3. After adjusting the bearing pressing amount by the bolt, the pressing amount of the bearing will change due to factors such as mechanical vibration during production, and even if a tightening nut is used to tighten it after adjustment, the pressing amount will still change during production, thereby affecting the straightness of the steel wire.

[0004] In summary, the traditional straightener group has the above-mentioned disadvantages of inconvenient adjustment, long adjustment time, and unstable production, which greatly affects the production efficiency and the stability of product quality. UTILITY MODEL CONTENTS
