Description

TECHNICAL FIELD

[0001] The utility model relates to strip steel coiling device technical field, concretely relates to a coiler upper guide plate device of swing cylinder drive crank connecting rod mechanism. BACKGROUND

[0002] The coiler is the mechanical equipment that coiling product, has the application in many industries. Coiler drive comes from electric power, fluid etc., generally by core equipment reel, auxiliary coiling equipment and auxiliary roll etc. constitute. In the product coiling process, the product is mainly formed on the reel, the reel is generally dragged by the motor, the auxiliary coiling equipment auxiliary roll generally adopts motor drag to rotate, fluid hydraulic cylinder drives auxiliary roll to move to help to coil smoothly, facilitate transportation.

[0003] In the strip steel production of metallurgical industry, the coiler is the rolling mill workshop auxiliary equipment that hot-rolled or cold-rolled steel material is curled into cylindrical shape, is arranged after finished product stand in hot strip steel continuous rolling mill, cold strip steel continuous rolling mill and wire rod rolling mill;In addition, it is also installed in continuous pickling unit, slitting, annealing, coating and various finishing units. In the hot-rolled strip steel production, in the strip steel coiling process, when the strip tail is coiled, the head of the strip steel is bent after the pinch roll and is coiled on the reel through the auxiliary roll. In this process, the upper guide plate plays a guiding role when the strip steel is coiled, preventing accidental impact and steel piling. Because the height of the upper guide plate does not change during the coiling process, when rolling thick gauge high-strength steel, the running track of the strip steel moves up, the strip steel directly contacts the working surface of the upper guide plate, causing adhesive wear, and the contact point adheres or welds, which produces a hard point that causes deep hard scratches on the surface of the strip steel, resulting in wear on the surface of the strip steel.

[0004] At present, a large number of full-hydraulic three-auxiliary roll underground coilers with Mitsubishi structure are used for strip steel coiling work, which uses a four-link mechanism upper guide plate to guide the strip steel into the coiler, and the auxiliary roll arm opens synchronously as the roll diameter increases, and the upper guide plate moves as the auxiliary roll arm opens. When the roll diameter of the steel coil gradually increases to the maximum roll diameter, the distance between the upper guide plate and the steel coil is very small. Once the connecting rod pin bushing wears out, the position of the upper guide plate moves down, causing the upper surface of the strip steel to contact and rub against the upper guide plate, resulting in quality loss of the strip steel surface scratches. At present, during use, due to the large amount of water vapor in the coiler, the connecting rod pin bushing is prone to rust and wear. To prevent the position of the upper guide plate from moving down, the upper guide plate pin bushing needs to be frequently repaired and replaced. Due to the small space, the repair is difficult and labor-intensive. Even so, the upper guide plate still often comes into contact with the surface of the strip steel, causing wear on the surface of the strip steel and resulting in quality loss, which has a certain impact on the quality of hot-rolled products. Therefore, the utility model provides a coiler upper guide plate device driven by a swing cylinder and a crank connecting rod mechanism to solve the above problems. UTILITY MODEL CONTENTS
