Embodiment Construction

[0013] figure 1 , 2 A structural diagram of a four-high rolling mill tire is shown. In the figure, the four-high rolling mill tire mainly includes a main frame 1, a front panel 2 and a rear panel 3, and a lower slider 4, a left slider 5, an upper slider 6 and four rollers are arranged in the main frame 1 , Needle bearings are arranged between each roller and its respective roller shaft, and a fixed connection is adopted between the roller shaft and the roller seat.

[0014] The first roller 7b is arranged on one end of the first roller seat 7a through the first roller shaft 7c, and the other end of the first roller seat 7a is threadedly connected with the first screw adjusting disc 7 to form the first roller mechanism. The first roller seat (7a) of a set of roller mechanism is directly arranged in the chute of the main frame 1. The second roller 8b is arranged on one end of the second roller seat 8a through the second roller shaft 8c, and the other end of the second roller ...

Abstract

A four-roller rolling mill mould belongs to the technical field of rolling of strip steel with rectangular section. A main frame of the four-roller rolling mill mould is provided with a lower slider, a left slider, an upper slider, four rollers and an adjusting mechanism inside. Each roller is fixed to one end of a roller seat via a respective roller shaft, and the other end of the roller seat is connected with a screw adjusting disc in a threaded way to form four roller mechanisms. One side of the first roller abuts to the circumferential surface of the second roller, one side of the second roller abuts to the circumferential surface of the third roller, one side of the third roller abuts to the circumferential surface of the fourth roller, and one side of the fourth roller abuts to the circumferential surface of the first roller. The size of a rolling piece is adjusted by turning a first adjusting screw, a second adjusting screw and the screw adjusting disc of each roller mechanism. The four-roller rolling mill mould is simple in structure and convenient in adjustment during usage, and rolled products are high in quality.

Description

technical field [0001] The invention relates to a tire for a four-high rolling mill, which belongs to the technical field of a rectangular-section strip rolling tire. Background technique [0002] Most of the existing rolling mills use two-roll molds. For the rolling of strips with rectangular cross-sections, it needs to be rolled twice, or two two-roll molds are used, arranged perpendicular to each other, to jointly complete the four sides of the rectangular cross-section strips. rolling. Because the two two-roll tires are far apart, they cannot effectively control the strip section at the same time, resulting in difficult product quality assurance. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a tire for a four-high rolling mill. The tire mold should have simple structure, convenient adjustment during use and high quality rolled products. [0004] The technical solution adopted in the...
