Problems solved by technology

[0008] The existing four-high rolling mills are mostly used for synchronous rolling of large work roll diameters, which cannot roll thin strips or extremely thin strips; the roll system is vertically distributed, and it is difficult to roll liquid, powder and granular metal raw materials; the existing asynchronous rolling mills The replacement of different speed ratios depends on the replacement of transmission gears, which is costly and inefficient, and the existing rolling mill rolls are all formed at one time, cannot be changed and disassembled, and have a single range of use
The current thin strip and ultra-thin strip production equipment in the state of metal, alloy and powder state cannot meet the demand, and the present invention is proposed under this background

Embodiment 1

[0053] The four-roll vertical distribution method roll system rolling mill includes a pressing device 1, a pair of vertically distributed work rolls 3 and a pair of support rolls 2, a housing 4 and a base 10, a tension motor 5, a main drive motor 7, a reel 8 and a tension roller 9. The arch 4 is vertically arranged. The contact surface 15 between the arch and the base is fixed on the base 10 by bolts. Both ends of the roll are fixed with sliding bearing housings. The roll and the bearing housing move at the same time. The upper supporting roller 2 bearing housing is balanced by The beam 18 is hoisted, the bearing seat of the lower supporting roller 2 is fixed at the bottom of the archway 4, and the bearing seat of the upper and lower work rolls 3 is connected by the spring 19 between the working rolls. 19 is fixed inside, the upper end of the work roll spring 19 is in contact with the lower surface of the upper work roll 3 bearing seat, there is no connection between the upper s...

Embodiment 2

[0057] Two-roll horizontally arranged horizontally. The rolling mill consists of two horizontally arranged work rolls 3, an arch 4 and a base 10, a main drive motor 7, a feeding port 11 and a discharge port 12. The arch 4 is arranged horizontally by two rolls. The contact surface 14 with the base is fixed on the base 10 by bolts. The described work roll 3 is a work roll 3 with a four-roll vertical arrangement that is disassembled, and the support roll 2 in the four-roll vertical arrangement roll system is used as the work roll 3 in a two-roll horizontal horizontal arrangement.

[0058] Turn on the power supply of the rolling mill system. During rolling, liquid, powder or particles are fed into the roll gap through the feeding port, and the finished strip is obtained after rolling.

Embodiment 3

[0060] The two-roll vertical arrangement method is composed of a pressing device 1, a pair of vertically distributed work rolls 3, a housing 4 and a base 10, a tension motor 5, a main drive motor 7, a reel 8 and a tension roller 9; The work roll 3 is the work roll 3 of the disassembled four-roller vertical arrangement. The supporting roll 2 of the four-roller vertical arrangement is used as the work roll 3 of the two-roller vertical arrangement. The archway 4 is arranged vertically. The contact surface 15 between the archway and the base is fixed on the base 10 by bolts.

[0061] Turn on the power supply of the rolling mill system to perform synchronous or asynchronous rolling of the thin strip blanks. The rolling process is carried out under the condition of strip tension. After multiple passes, the thickness range is below 0.05mm to below 0.005mm. The functional material finished product of the thin strip.

Abstract

The invention relates to a multifunctional rolling mill for producing thin metal straps and ultra-thin metal straps and belongs to the field of metal rolling devices. The multifunctional rolling mill comprises a pressing-down device, a memorial archway, a base, a roll system, a roll gap adjusting device, a main transmission motor and a tension motor. The memorial archway is fixed on the base through a bolt, the pressing-down device is fixed on the memorial archway through a pressing-down lead screw, the roll system is placed in the memorial archway, a bearing seat limits horizontal movement of the roll system, the roll system can vertically slide in a memorial archway window, the roll gap adjusting device uplifts a spring through the pressing-down lead screw and a balance beam to be connected with the memorial archway, the main transmission motor is connected with the roll system through a universal spindle, the tension motor is fixed on the base through a bolt, and the roll system adopts a four-roller vertical distributing mode, a two-roller vertical distributing mode or a two-roller horizontal distributing mode. The multifunctional rolling mill can be used for rolling liquid, powdery and particle-shaped ultra-thin metal and alloy strap materials and has a continuously variable function, a stepless adjusting function and a function of optionally selecting transmission speed ratio of vertical rollers.

Description

[0001] Technical field [0002] The invention relates to a multifunctional rolling mill for producing thin metal strips and extremely thin strips, and belongs to the field of metal rolling equipment. Background technique [0003] With the development of micro-manufacturing technology and micro-forming technology, the demand for thin strips and ultra-thin strips of metals, alloys and powder materials has become more and more urgent.
