Description

Technical Field

[0001] The invention belongs to the technical field of rolling mills, and in particular relates to a working roll adjustment mechanism for a copper foil rolling mill. Background Art

[0002] During the copper foil rolling process, the rolling mill will have roll shifting, which has many benefits. First, it helps to improve the wear of the rolls. Reasonable roll shifting can make the roll surface wear more evenly, extend the service life of the rolls by dispersing the wear area, and reduce the cost of roll use, which is of great significance for long-term, large-scale rolling production; second, it can improve the plate shape control ability. When rolling high-precision copper foil strips, the plate shape can be dynamically adjusted with the help of roll shifting, effectively dealing with the poor plate shape problems caused by factors such as uneven distribution of rolling force and changes in roll thermal convexity, thereby improving the quality stability of the product.

[0003] At the same time, rolling mill roll shifting also has negative effects. On the one hand, it has an adverse effect on product quality, causing uneven thickness and plate defects such as edge waves and middle waves in the rolled material, reducing the dimensional accuracy and appearance quality of the product, and affecting the product yield rate; on the other hand, it will aggravate the wear of equipment components, causing abnormal stress and friction between rollers, bearings, arches and other components, accelerating the wear rate of these components, and thus affecting the stability of equipment operation.

[0034] Working principle: Before rolling the copper foil strip 1, first adjust the spacing between the upper working roll 3 and the lower working roll 4, which is specifically achieved by adjusting the position of the spacing adjustment seat 6. During the adjustment, since the positions of the working rolls, the sliding sleeve 8 and the spacing adjustment seat 6 change, it is necessary to adjust the tensioning synchronous wheel 46 to adapt to the spacing of the spacing adjustment seat 6.

[0035] Then start rolling, such as Figure 2 As shown, the copper foil strip 1 flows from left to right, the upper working roller 3 rotates counterclockwise, and the lower working roller 4 rotates clockwise. In this process, the upper working roller 3 corresponds to the upper shifting roller adjustment mechanism 10, and the state of the first adjustment ratchet assembly 29 is as follows: Figure 7 As shown, the state of the second adjustment ratchet assembly 35 is as follows Figure 8 As shown, the rotation of the first driven gear 25 and the second driven gear 26 will not cause the drive shaft 13 to rotate. In this process, the elastic guide column 17 of the upper shifting roller adjustment mechanism 10 corresponding to the upper working roller 3 is located in the first rotary groove 18.

[0036] In the lower shifting roller adjustment mechanism 11 corresponding to the lower working roller 4, the state of the second adjustment ratchet assembly 35 is as follows: Fig.14As shown, the first adjusting ratchet assembly 29 is in the state as Fig.15 As shown, the rotation of the first driven gear 25 and the second driven gear 26 will not cause the driving shaft 13 to rotate, and the elastic guide column 17 of the lower shifting roller adjustment mechanism 11 corresponding to the lower working roller 4 is located in the first rotary groove 18.

[0037] The above process is a normal working state.

[0038] When the working rolls need to be driven to shift according to the requirements, during the normal rolling process, the servo motor 47 is controlled to rotate. The double-sided toothed synchronous belt 44 drives the driving gear 41 to rotate, and the driving gear 41 rotates while the first adjusting arc plate 34 and the second adjusting arc plate 40 rotate, thereby adjusting the first adjusting ratchet assembly 29 and the second adjusting ratchet assembly 35, thereby rotating the driving shaft 13, and the rotation of the driving shaft 13 causes the elastic guide column 17 to move along the driving track groove, thereby driving the working roller to move. The direction of movement of the upper working roller 3 is opposite to that of the lower working roller 4 and they move simultaneously.

[0039] It should be noted that after the servo motor 47 drives the double-sided toothed synchronous belt 44 to rotate, there are three states, namely, state 1: original position, at this time, Figure 7 , Figure 8 , Fig.14 , Fig.15 , the upper working roll 3 corresponds to the first adjusting ratchet assembly 29 and the second adjusting ratchet assembly 35, and the lower working roll 4 corresponds to the second adjusting ratchet assembly 35 and the first adjusting ratchet assembly 29. In this state, the upper working roll 3 and the lower working roll 4 do not move.

[0040] State 2: In the case of state 1, the servo motor 47 starts and rotates counterclockwise at a fixed angle, driving the double-sided toothed synchronous belt 44 to rotate counterclockwise, thereby driving the driving gear 41 to rotate, wherein the driving gear 41 corresponding to the upper working roll 3 rotates counterclockwise, and the driving gear 41 corresponding to the lower working roll 4 rotates clockwise, and finally the first pawl 32 of the first adjusting ratchet assembly 29 corresponding to the upper working roll 3 is engaged with the first ratchet gear 30, and the second pawl 38 of the second adjusting ratchet assembly 35 corresponding to the upper working roll 3 is not engaged with the second ratchet gear 36; the first pawl 32 of the first adjusting ratchet assembly 29 corresponding to the lower working roll 4 is not engaged with the first ratchet gear 30, and the second pawl 38 of the second adjusting ratchet assembly 35 corresponding to the lower working roll 4 is engaged with the second ratchet gear 36. In this state, the driving shaft 13 corresponding to the upper working roll 3 rotates clockwise, thereby driving the upper working roll 3 to move toward the archway 2, and the driving shaft 13 corresponding to the lower working roll 4 rotates counterclockwise, thereby driving the lower working roll 4 to move away from the archway 2.

[0041] State three: In the state one, the servo motor 47 starts and rotates clockwise at a fixed angle, driving the double-sided toothed synchronous belt 44 to rotate clockwise, thereby driving the driving gear 41 to rotate, wherein the driving gear 41 corresponding to the upper working roll 3 rotates clockwise, and the driving gear 41 corresponding to the lower working roll 4 rotates counterclockwise, and finally the first pawl 32 of the first adjusting ratchet assembly 29 corresponding to the upper working roll 3 is not engaged with the first ratchet gear 30, and the second pawl 38 of the second adjusting ratchet assembly 35 corresponding to the upper working roll 3 is engaged with the second ratchet gear 36; the first pawl 32 of the first adjusting ratchet assembly 29 corresponding to the lower working roll 4 is engaged with the first ratchet gear 30, and the second pawl 38 of the second adjusting ratchet assembly 35 corresponding to the lower working roll 4 is not engaged with the second ratchet gear 36. In this state, the driving shaft 13 corresponding to the lower working roll 4 rotates counterclockwise, thereby driving the upper working roll 3 to move away from the archway 2, and the driving shaft 13 corresponding to the lower working roll 4 rotates clockwise, thereby driving the lower working roll 4 to move closer to the archway 2.

[0042] The switching process of the three states is from state one to state two, then from state two to state one, and finally to state three, and finally to state one. After this process, the upper working roll 3 moves toward the arch 2 from the normal state and then returns to the normal state, and the lower working roll 4 moves away from the arch 2 from the normal state and then returns to the normal state.

[0043] It should be noted that when the working roll is moving, the driving gear 24 is always meshed with the corresponding first driven gear 25 and the transmission gear 28 .

Within the technical scope disclosed by the present invention, technicians familiar with the technical field can make equivalent replacements or changes based on the technical scheme and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
