Embodiment 1

[0048] Please refer to figure 1 with figure 2 , the present embodiment provides a single-side rolling mill 100 , which mainly includes a stand 110 , an upper rolling system 140 and a lower plate rolling device 170 . Wherein, the frame 110 is used for fixedly installing other components of the whole unilateral rolling mill 100, and the upper roller system 140 is horizontally installed in the frame 110, and it includes an upper roller 142 that can rotate around a horizontal axis; a lower plate rolling device 170 It is arranged below the upper roller 142 and includes a lower rolling plate 171 horizontally arranged below the upper roller 142 . A roll gap is arranged between the upper roll 142 and the lower rolling plate 171, and rolling is realized after the rolling piece passes through the above-mentioned roll gap.

[0049] Please continue to refer Figure 1-Figure 4 , the upper roller system 140 is installed on the frame 110, and the upper roller system 140 can move along th...

Embodiment 2

[0058] This embodiment provides a plate rolling method, which uses the single-side rolling mill 100 provided in Embodiment 1, and specifically includes the following steps:

[0059] a. Apply lubricating oil or release agent on the lower rolling plate 171;

[0060] b. According to the initial thickness and reduction of the rolled piece, adjust the size of the roll gap through the reduction component;

[0061] c. After driving the upper roller system 140 and making the rotation speed of the upper roller system 140 stable, the lower rolling plate is pushed along the first reference direction through the driving assembly so that the rolled piece smoothly enters the rolling area for rolling. Moreover, the speed of the lower rolling plate 171 and the linear velocity of the upper rolling plate 142 maintain a certain difference, thereby further reducing the rolling force, enhancing the shearing effect, and improving the plastic deformation through the asynchronous manner of the upper ...

Abstract

The invention provides a unilateral roll system rolling mill and a plate rolling method, and belongs to the field of plate machining equipment. The rolling mill mainly comprises a rack, an upper rollsystem and a lower plate rolling device. The rack is used for allowing other parts of the whole rolling mill to be fixedly mounted. The upper roll system is horizontally mounted on the rack and comprises an upper roll capable of rotating around the horizontal axis. The lower rolling plate device is arranged below the upper roll, and comprises a lower rolling plate horizontally arranged below the upper roll. A roll gap is arranged between the upper roll and the lower rolling plate, and a rolled piece passes the roll gap to be rolled. According to the rolling mill and the method, the function ofasymmetrical rolling is achieved, the horizontal component of positive pressure is increased, and the stress state of the rolled piece is changed; and rolling force can be reduced, the shearing effect can be enhanced, and the plastic deformation capacity can be improved.

Description

technical field [0001] The invention relates to the field of plate processing equipment, in particular to a single-side rolling mill and a plate rolling method. Background technique [0002] Improving the quality of strip production, reducing production costs, and increasing production efficiency are the eternal pursuits in the strip production process. Scholars and experts at home and abroad have designed and manufactured various types of rolling mills. A conventional rolling mill consists of two counter-rotating work rolls between which the workpiece is placed. The two working rolls drive the rolling piece to move through friction; the working roll exerts rolling force on the rolling piece, causing the rolling piece to produce plastic deformation, and completes the rolling process of the rolling piece from thick to thin or forming a specific shape. By changing the size of the gap between the two work rolls, the purpose of rolling different thicknesses of rolled pieces can...
