Embodiment 1

[0020] Refer to attached figure 1 To attach image 3 The shown reel for coiling steel strips includes a pull rod 1, a coiling shaft 2, a closing bar 5 and a fan-shaped plate, and the pull rod 1 is arranged in the through hole at the center of the coiling shaft 2, so that The outer surface of the coiling shaft 2 described above is provided with fan-shaped plates and closing strips 5, the fan-shaped plates include a jaw fan-shaped plate 7 and three common fan-shaped plates 4, the fan-shaped plates are evenly distributed along the circumference of the coiling shaft 2, and the jaws are fan-shaped. The plate 7 can perform circumferential relative rotation and radial expansion and contraction relative to the take-up shaft 2, and the ordinary fan-shaped plate 4 can perform radial expansion and contraction relative to the take-up shaft 2, and is arranged between adjacent fan-shaped plates on the take-up shaft 2 There is a telescopic control assembly that controls the expansion and co...

Embodiment 2

[0022] On the basis of the foregoing scheme, the outer surface of the coiling shaft 2 is provided with a plurality of fan-shaped plate assembly grooves 11, and a guide block 12 corresponding to the fan-shaped plate assembly grooves 11 is provided under the fan-shaped plate. The inside of the guide block 12 is along the A plurality of holes with stepped surfaces are arranged in the axial direction, and bolts 13 and disc springs 8 are arranged in the holes, and the ends of the bolts 13 are connected with the take-up shaft 2 , and guide arc surfaces 10 are arranged on both sides of the guide block 12 .

Embodiment 3

[0024] On the basis of Embodiment 1, further, the telescopic control assembly includes a pull rod 1, an inner wedge 3 and a closing bar 5, grooves are arranged between adjacent fan-shaped plates on the take-up shaft 2, and the inner wedge 3 And the closing strip 5 is arranged in the groove, and a plurality of wedge surfaces are distributed on the outer surface of the inner wedge 3, and the inside of the closing strip 5 is provided with an inclined surface corresponding to the wedge surface, and the inner wedge 3 ends are fixed with nuts. The cross joint 17 at the end of the tie rod 1 is connected. When the pull rod 1 is pulled, the inner wedge 3 can move axially, and then drive the closing bar 5 to move radially, so as to realize the expansion of the fan-shaped plate.

Abstract

The invention discloses a coiling roller for coiling strip steel, which comprises a pulling rod, a coiling shaft, a closed strip and a fan-shaped plate, wherein the pulling rod is arranged in a through hole at the center of the coiling shaft; the fan-shaped plate and the closed strip are arranged on the surface outside the coiling shaft; the fan-shaped plate comprises a jaw fan-shaped plate and a plurality of common fan-shaped plates; the jaw fan-shaped plate can perform circumferential relative rotation and radial stretching relative to the coiling shaft; the common fan-shaped plates can perform radial stretching relative to the coiling shaft; and stretching control components, which are used for controlling the radial stretching of the fan-shaped plates and are capable of forming proper circles together with the fan-shaped plates, are arranged between the adjacent fan-shaped plates on the coiling shaft. The coiling roller for coiling the strip steel, provided by the invention, has the advantages that the problem of horizontal indentation caused by the sudden change in the diameter of the steel coil on the surface of inter-layer circles of strip steel during the strip steel coiling process is perfectly solved, the quality of the strip steel is increased and the waste is reduced.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a reel used in strip steel coiling. Background technique [0002] Existing reels usually have a cylindrical structure. During the coiling process of cold-rolled strip steel, at the end of the steel strip, the first layer of strip steel tail cannot be in complete rigid contact with the outer circle of the reel, thus transitioning to the second layer. Therefore, whether it is a reel with a jaw or a reel without a jaw, when the strip is coiled, the second layer of strip at the head position will form a certain tension under the action of the reel expansion force and the strip tension In this way, it is easy to cause transverse indentation of the strip steel in the inner layer and reduce the surface quality of the strip. use, resulting in a lot of waste. At present, there are mainly several methods such as adding rubber sleeves and adopting closed structure reels to reduce the indentation...
