When the sizes of the four corners of the square tube are specifically required by some products, the universal roller can not meet the product requirements of customers. Because the R sizes of the four corners of the square and rectangular tube are mainly formed by solid bending and rolling, the radius size of the R corner is directly related to the R size of an upper shaft roller pressed on the strip steel. Therefore, the product needs to have a proper roller to reach the specified R angle size. Generally, when the R-angle size of a product is required, the upper roll commonly used for the last flat roll of the first bend angle and the second bend angle is often replaced with a dedicated roll corresponding to the specified R-value of the product for rolling, and sometimes, not only the last flat roll of the first bend angle and the second bend angle but also more stands are replaced to meet the requirement of the product.

The existing conventional unit mostly adopts a mode of additionally arranging an upper shaft system and a roller on line when replacing the upper shaft system, when the roller needs to be replaced, the roller is firstly arranged on a spare part shaft system, then a gland nut for lifting the upper shaft on the unit is loosened, an upper shaft lifting device is removed, then the upper shaft system is removed, a new upper shaft system is arranged in a memorial archway frame, then the upper shaft lifting device is arranged and connected with the upper shaft system, and then the gland nut of the upper shaft lifting device is locked again. The roll changing process is a test on the labor intensity and the operation safety of workers because the whole upper shaft is heavy due to the fact that the length of the upper shaft is long when the length of the upper shaft is affected by the lower roll and the side roll, and the whole upper shaft is heavy.

Further, the first side roller 61 and the second side roller 62 are in a circular truncated cone shape, and the included angle between the inclined surface and the horizontal plane is 70-75 degrees, and in the embodiment, 72 degrees is adopted.

Because the rolling of the square and rectangular tube is in a symmetrical form, the lateral force in the horizontal direction generated in the rolling process is borne on the same rack, so that the lateral force belongs to the internal force of the rack, and the lateral force and the internal force are mutually counteracted. When the roller needs to be changed, the inserting plate 34 on the side face of the movable sliding block where the upper roller shaft system 2 is located is pulled out only by separating the connecting rod 43 between the upper roller shaft system lifting devices, and the pressing plate 33 with the kidney-shaped hole above the closed frame moves towards two sides along the kidney-shaped hole so that the pressing plate can be directly lifted out after no longer pressing on the sliding block. And then, the upper roller shaft system to be replaced is integrally transferred into the closed frame to connect the side surface of the sliding block and the upper flashboard 34 of the worm gear lead screw lifter, and after the waist-shaped hole pressing plate 33 is reset, the connecting rod 43 between the upper roller shaft system lifting devices is connected to complete the roller replacement work. Therefore, when the upper roll is replaced, workers do not need to climb to a place with more than two meters to remove the locking nut of the upper shaft lifting device and then hang the upper shaft lifting device. And the weight of the spare parts of the upper shaft can be greatly reduced after the structure is adopted, and meanwhile, the cost of the spare parts can be reduced by half. Has more advantages in the aspects of economy and operation safety.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
