Description

Steel coil winding tool

Technical Field

The utility model belongs to the technical field of the coil of strip is violently, rip cutting equipment, especially, relate to a coil of strip rolling frock.

Background

The steel coil commodity is generally a large product with more than 20 tons. The steel coil is also called coil steel, is formed into a coil shape by hot pressing and cold pressing steel materials, and is convenient for storage, transportation and processing of various steel plate products, steel strip products and the like. In order to improve the quality and the yield of steel coil products in the industry, a plurality of special production lines with different inner diameters are often arranged, for example, the steel coil special production lines with the inner diameters of 508MM, 610MM and 760MM, the investment of one production line is more than ten million levels, and the cost of a production plant is greatly increased. At present, there is also trapezoidal short tooth caliper type reducing coiling mechanism as shown in fig. 1, this coiling mechanism includes an oil cylinder 1, a piston rod 2 is provided on the oil cylinder 1, an oblique block adjusting mechanism 4 is provided on the outside of the oil cylinder 1, the end of the outside of the oblique block adjusting mechanism 4 is connected with a circular flange 12, the circular flange 12 is connected with the oil cylinder oil plug rod 2 at the same time, a plurality of oblique protrusions are provided on the oblique block adjusting mechanism 4, a plurality of arc plates 5 are movably provided on the outside along the circumference to form a coiling drum, oblique protrusions and sliding connections corresponding to the oblique protrusions of the oblique block adjusting mechanism 4 are provided on the inner side of each arc plate 5, the arc plates 5 are pressed against the oblique block adjusting mechanism 4 through elastic components such as disc springs. When the piston rod 2 of the oil cylinder 1 moves leftwards, each arc-shaped plate 5 moves downwards vertically under the action of a disc spring or other elastic components, the outer diameter of a winding drum formed by each arc-shaped plate 5 is reduced, and when the piston rod 2 of the oil cylinder 1 moves rightwards, each arc-shaped plate 5 overcomes the action of the disc spring or other elastic components and moves upwards vertically, and the outer diameter of the winding drum formed by each arc-shaped plate 5 is increased. However, the contact area of each arc plate and the inner ring of the steel coil is small, so that the coiling and uncoiling are not tight easily after the coiling drum formed by each arc plate 5 is subjected to diameter reduction, the uncoiling condition occurs, and the diameter-variable coiling device is in a short-line state when being in contact with the inner ring of the steel coil to be processed due to the fact that the diameter-variable coiling device is in a trapezoidal short-tooth type caliper structure matched with a hydraulic device to realize diameter reduction, the surface of the inner ring of a commodity to be processed is often severely scratched when equipment is started, and the yield is greatly reduced.
