摘要: 롤링 밀의 통과 라인을 따라 이동하는 제품을 각각 추진 또는 저지하기 위한 핀치 롤 유닛은 평행한 제1 축 주위로 회전시키기 위해 장착된 한 쌍의 레버를 포함한다. 롤 샤프트는 그 각각의 레버의 제1 축에 평행한 제2 축 주위로 회전되기 위해 각각 저널결합되고, 레버에 의해 지지된다. 핀치 롤은 상기 롤 샤프트에 의해 작동되고 제품을 수용하기 위한 갭을 그 사이에 형성한다. 전동식 제1 모터는 제1 축 주위로 상기 레버를 회전시키고, 제품으로부터 이격된 개방 위치와 제품과 접촉하여 그 사이에 제품을 파지하는 폐쇄 위치 사이에서 상기 핀치 롤을 이동시키도록 연동 수단을 통해 작동 가능하다. 전동식 제2 모터는 핀치 롤을 회전 가능하게 구동시킨다.

摘要: PURPOSE: To provide hot rolling mills of the type producing bar and rod products to obtain improvements in the pinch roll units and associated controls employed to propel and/or retard the movement of such products at various places along the mill pass line. CONSTITUTION: In a pinch roll unit(24,26) for either propelling or retarding a product moving along the pass line (PL) of a rolling mill, the pinch roll unit comprises a pair of levers mounted for rotation about parallel first axes; roll shafts carried by the levers, each roll shaft being journalled for rotation about a second axis parallel to the first axis of its respective lever; pinch rolls(34) carried by the roll shafts, the pinch rolls defining a gap there between for receiving the product; an electrically powered first motor; linkage means for mechanically coupling the first motor to the levers, the first motor being operable via the linkage means to rotate the levers about the first axes and to move the pinch rolls between open positions spaced from the product, and close positions contacting and gripping the product therebetween; and an electrically powered second motor for rotatably driving the pinch rolls, wherein the linkage means comprises a disc crank driven by the first motor for rotation about a third axis parallel to the first and second axes, and a pair of link members, each link member being pivotally coupled at opposite ends to the disc crank and to a respective one of the levers, and wherein the pinch roll unit further comprises detector means (HMD-1,HMD-2) for generating a signal indicative of the presence of the product at a location along the pass line preceding the gap defined between the pinch rolls, and control means responsive to the signal for operating the first motor to move the pinch rolls between the open and closed positions by rotating the levers about the first axes.
