Description
本發明是有關於一種輥軋機、冷軋方法和鋼板製造方法。The present invention relates to a roller rolling machine, a cold rolling method and a steel plate manufacturing method.
例如，於冷軋鋼板等的生產線中，在冷軋過程中有時會由於各種因素而產生振動。作為輥軋對象材的鋼板的板厚有因該振動而週期性地變動之虞，因此重要的是於產生振動時抑制振動，使其不影響輥軋對象材。For example, in the production line of cold-rolled steel plates, vibration may occur due to various factors during the cold-rolling process. The thickness of the steel plate, which is the rolling target, may change periodically due to this vibration, so it is important to suppress the vibration when it occurs so that it does not affect the rolling target.
例如，於專利文獻1中揭示了一種能夠抑制因供給至輥軋機的機架（stand）的輥軋油而產生水平方向上的抖動（振動）的冷軋設備及冷軋方法。 [現有技術文獻] [專利文獻] For example, Patent Document 1 discloses a cold rolling device and a cold rolling method capable of suppressing horizontal vibration (vibration) caused by rolling oil supplied to a stand of a rolling machine. [Prior Art Document] [Patent Document]
專利文獻1：日本專利第7020530號公報Patent document 1: Japanese Patent No. 7020530
[發明所欲解決之課題] 且說，於此種輥軋機中，例如除了如所述現有技術般的抑制由輥軋油引起的振動的方法以外，提出了一種藉由在機架所包括的輥軸承座的襯墊安裝防振橡膠等彈性構件來抑制輥軋過程中的振動的方法。 [Problems to be solved by the invention] In addition, in this type of rolling machine, in addition to the method of suppressing vibration caused by rolling oil as in the prior art, a method of suppressing vibration during rolling by installing an elastic member such as vibration-proof rubber on the pad of the roller bearing seat included in the frame is proposed.
然而，於將彈性構件在輥軋方向上積層安裝於輥軸承座的襯墊的結構中，彈性構件的與輥軸承座的相反的一側的露出面磨損，有難以於工業上使用之虞。However, in a structure in which the elastic member is stacked and mounted on the pad of the roller bearing seat in the rolling direction, the exposed surface of the elastic member on the opposite side of the roller bearing seat may be worn, which may make it difficult to use in industry.
本發明是鑒於所述課題而成，其目的在於提供一種能夠於抑制輥軸承座的襯墊的磨損的同時抑制輥軋過程中的振動的輥軋機、冷軋方法和鋼板製造方法。 [解決課題之手段] The present invention is made in view of the above-mentioned problem, and its purpose is to provide a roller rolling machine, cold rolling method and steel plate manufacturing method that can suppress the wear of the roller bearing seat lining and the vibration during the roller rolling process.

圖3是圖2的工作輥軸承座襯墊30的放大圖。如圖3所示，工作輥軸承座襯墊30例如具有第一襯板36、第二襯板38及彈性構件37。彈性構件37及第二襯板38相對於第一襯板36在輥軋方向X上積層。Fig. 3 is an enlarged view of the working roller bearing seat lining 30 of Fig. 2. As shown in Fig. 3, the working roller bearing seat lining 30 has, for example, a first lining plate 36, a second lining plate 38 and an elastic member 37. The elastic member 37 and the second lining plate 38 are stacked in the rolling direction X relative to the first lining plate 36.
第一襯板36構成為沿著工作輥軸承座20的凹部20a的底部延伸的矩形的板狀。於第一襯板36設置有緊固件50的軸部50b在輥軋方向X上貫通的開口部36a。緊固件50例如為螺栓或螺釘等固定構件，將工作輥軸承座襯墊30與工作輥軸承座20固定。第一襯板36及第二襯板38例如包含金屬材料。The first liner 36 is formed into a rectangular plate extending along the bottom of the recess 20a of the working roller bearing seat 20. The first liner 36 is provided with an opening 36a through which the shaft 50b of the fastener 50 passes in the rolling direction X. The fastener 50 is a fixing member such as a bolt or a screw, and fixes the working roller bearing seat liner 30 and the working roller bearing seat 20. The first liner 36 and the second liner 38 are made of metal material, for example.
於本實施方式中，第一襯板36的厚度W1被設定得較第二襯板38的厚度W2或彈性構件37的厚度而言厚。具體而言，第一襯板36的厚度W1被設定為工作輥軸承座襯墊30的整體厚度的約一半左右，確保了利用緊固件50進行緊固所需的剛性或強度。於本實施方式中，彈性構件37的厚度被設定為與第二襯板38的厚度W2大致相同。In the present embodiment, the thickness W1 of the first liner 36 is set to be thicker than the thickness W2 of the second liner 38 or the thickness of the elastic member 37. Specifically, the thickness W1 of the first liner 36 is set to be about half of the overall thickness of the working roller bearing seat liner 30, ensuring the rigidity or strength required for fastening with the fastener 50. In the present embodiment, the thickness of the elastic member 37 is set to be substantially the same as the thickness W2 of the second liner 38.
第二襯板38於輥軋方向X上位於第一襯板36的與工作輥軸承座20相反的一側。第二襯板38構成為沿著第一襯板36延伸的矩形的板狀。於第二襯板38設置有收容緊固件50的頭部50a的開口部38a。開口部38a例如構成為較緊固件50的頭部50a大一圈的圓孔（讓位孔）。The second liner 38 is located on the side of the first liner 36 opposite to the working roller bearing seat 20 in the roller rolling direction X. The second liner 38 is configured as a rectangular plate extending along the first liner 36. An opening 38a for accommodating the head 50a of the fastener 50 is provided on the second liner 38. The opening 38a is configured as a round hole (clearance hole) that is larger than the head 50a of the fastener 50, for example.
彈性構件37例如是防振橡膠等，於輥軋方向X上位於第一襯板36與第二襯板38之間。彈性構件37構成為沿著第一襯板36延伸的矩形的板狀，例如接著固定於第一襯板36及第二襯板38。彈性構件37能夠藉由在第一襯板36與第二襯板38之間進行彈性變形來吸收沿著輥軋方向X的振動。The elastic member 37 is, for example, a vibration-proof rubber, and is located between the first liner 36 and the second liner 38 in the rolling direction X. The elastic member 37 is configured as a rectangular plate extending along the first liner 36, and is, for example, fixed to the first liner 36 and the second liner 38. The elastic member 37 can absorb vibration along the rolling direction X by elastically deforming between the first liner 36 and the second liner 38.
另外，於彈性構件37設置有收容緊固件50的頭部50a的開口部37a。開口部37a例如構成為較緊固件50的頭部50a大一圈的圓孔（讓位孔），與第二襯板38的開口部38a於輥軋方向X上排列。於本實施方式中，緊固件50並非對工作輥軸承座襯墊30整體進行緊固，而是僅對第一襯板36進行緊固，藉此利用彈性構件37的彈性力來抑制緊固件50的緊固鬆動。In addition, the elastic member 37 is provided with an opening 37a for accommodating the head 50a of the fastener 50. The opening 37a is, for example, a round hole (a clearance hole) that is larger than the head 50a of the fastener 50, and is arranged with the opening 38a of the second liner 38 in the roller direction X. In this embodiment, the fastener 50 does not fasten the entire working roller bearing seat liner 30, but only fastens the first liner 36, thereby utilizing the elastic force of the elastic member 37 to suppress the fastening and loosening of the fastener 50.
於本實施方式中，彈性構件37及第二襯板38此兩者加在一起的厚度被設定得較緊固件50的頭部50a的厚度而言厚。即，彈性構件37及第二襯板38的厚度被設定為緊固件50的頭部50a不會自開口部37a、開口部38a向輥軋方向X突出的厚度。In this embodiment, the thickness of the elastic member 37 and the second liner 38 added together is set to be thicker than the thickness of the head 50a of the fastener 50. That is, the thickness of the elastic member 37 and the second liner 38 is set to a thickness that the head 50a of the fastener 50 does not protrude from the openings 37a and 38a in the rolling direction X.
另外，於本實施方式中，例示了於工作輥軸承座襯墊30設置有第一襯板36、第二襯板38及彈性構件37的情況，但並不限定於該例，亦可設置於圖2所示的中間輥軸承座襯墊31、或支承輥軸承座襯墊32。換言之，只要於工作輥軸承座襯墊30、中間輥軸承座襯墊31及支承輥軸承座襯墊32中的至少一個中設置有第一襯板36、第二襯板38及彈性構件37即可。In addition, in the present embodiment, the first lining plate 36, the second lining plate 38 and the elastic member 37 are provided on the working roller bearing seat lining 30, but it is not limited to this example, and they may also be provided on the intermediate roller bearing seat lining 31 or the supporting roller bearing seat lining 32 shown in FIG. In other words, as long as the first lining plate 36, the second lining plate 38 and the elastic member 37 are provided in at least one of the working roller bearing seat lining 30, the intermediate roller bearing seat lining 31 and the supporting roller bearing seat lining 32, it will be sufficient.
另外，於本實施方式中，關於機架3以外的其他的機架4～6，例如於工作輥軸承座襯墊30亦設置有第一襯板36、第二襯板38及彈性構件37。其他的機架4～6的結構與所述機架3的結構大致相同。設置有第一襯板36、第二襯板38及彈性構件37的機架3～機架6的數量並不限定於四個，例如可為一個，亦可為兩個或三個。In addition, in the present embodiment, regarding the other frames 4 to 6 other than the frame 3, for example, the first liner 36, the second liner 38 and the elastic member 37 are also provided on the working roller bearing seat pad 30. The structures of the other frames 4 to 6 are substantially the same as the structure of the frame 3. The number of the frames 3 to 6 provided with the first liner 36, the second liner 38 and the elastic member 37 is not limited to four, and may be one, two or three, for example.
如以上般，於本實施方式中，冷連輥軋機1（輥軋機）包括對鋼板2（輥軋對象材）進行輥軋的多個機架3～6，多個機架3～6中的至少一個機架3包括：至少一對工作輥10（輥軋輥）；工作輥軸承座20（輥軸承座），能夠旋轉地支撐工作輥10；以及工作輥軸承座襯墊30（輥軸承座襯墊），所述工作輥軸承座襯墊30（輥軸承座襯墊）具有：第一襯板36，安裝於工作輥軸承座20；第二襯板38，相對於第一襯板36在輥軋方向X上積層；以及彈性構件37，夾持於第一襯板36與第二襯板38之間。As described above, in this embodiment, the cold continuous roll-rolling machine 1 (roll-rolling machine) includes a plurality of frames 3 to 6 for rolling a steel plate 2 (rolling target material), and at least one frame 3 of the plurality of frames 3 to 6 includes: at least one pair of working rollers 10 (rolling rollers); a working roller bearing seat 20 (roller bearing seat) capable of rotatably supporting the working roller 10; and The working roller bearing seat lining 30 (roller bearing seat lining) comprises: a first lining plate 36 mounted on the working roller bearing seat 20; a second lining plate 38 stacked in the rolling direction X relative to the first lining plate 36; and an elastic member 37 clamped between the first lining plate 36 and the second lining plate 38.
根據此種結構，例如藉由將彈性構件37夾持配置於在輥軋方向X上積層的第一襯板36與第二襯板38之間，可抑制彈性構件37在與工作輥軸承座20的相反的一側（軋機機架40的項目塊41側）露出而磨損。藉此，可提供一種能夠於抑制工作輥軸承座襯墊30的磨損的同時抑制輥軋過程中的振動的冷連輥軋機1、冷軋方法和鋼板2的製造方法。According to this structure, for example, by sandwiching and arranging the elastic member 37 between the first liner 36 and the second liner 38 stacked in the rolling direction X, it is possible to prevent the elastic member 37 from being exposed and worn on the side opposite to the working roller bearing seat 20 (the side of the project block 41 of the rolling machine frame 40). Thereby, a cold continuous roller rolling machine 1, a cold rolling method, and a method for manufacturing a steel plate 2 that can suppress the wear of the working roller bearing seat liner 30 and suppress vibration during the rolling process can be provided.
另外，於本實施方式中，於多個機架3～6設置有具有第一襯板36、第二襯板38及彈性構件37的工作輥軸承座襯墊30。In addition, in the present embodiment, a working roller bearing seat liner 30 having a first liner 36, a second liner 38 and an elastic member 37 is provided on the plurality of frames 3 to 6.
根據此種結構，例如可藉由設置於多個機架3～6的工作輥軸承座襯墊30的彈性構件37來抑制輥軋過程中的振動，進而可更可靠地抑制鋼板2的板厚因輥軋過程中的振動而週期性地變動。According to this structure, for example, the elastic member 37 provided on the working roller bearing seat pad 30 of the plurality of frames 3 to 6 can suppress vibration during rolling, thereby more reliably suppressing the periodic variation of the thickness of the steel plate 2 due to vibration during rolling.
另外，於本實施方式中，第一襯板36經由在輥軋方向X上貫通的緊固件50緊固於工作輥軸承座20，於第二襯板38及彈性構件37設置有收容緊固件50的頭部50a的開口部38a、開口部37a。In addition, in this embodiment, the first liner 36 is fastened to the working roller bearing seat 20 via the fastener 50 penetrating in the roller direction X, and the second liner 38 and the elastic member 37 are provided with openings 38a and 37a for accommodating the head 50a of the fastener 50.
根據此種結構，例如可並非對工作輥軸承座襯墊30整體進行緊固，而是僅對第一襯板36進行緊固，因此可利用彈性構件37的彈性力來抑制緊固件50的緊固鬆動。According to this structure, for example, the entire working roller bearing seat liner 30 may not be tightened, but only the first liner 36 may be tightened, so the elastic force of the elastic member 37 can be used to suppress the tightening and loosening of the fastener 50.
以上，例示了本發明的實施方式，但所述實施方式為一例，並不意圖限定發明的範圍。所述實施方式能夠以其他各種形態來實施，可於不脫離發明的主旨的範圍內進行各種省略、置換、組合、變更。另外，各結構或形狀等規格（結構、或種類、方向、形式、大小、長度、寬度、厚度、高度、數量、配置、位置、材質等）可適宜地變更來加以實施。 [產業上之可利用性] The above examples illustrate the implementation of the present invention, but the implementation is an example and is not intended to limit the scope of the invention.
