Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cold rolling CVC continuous rolling mills, and in particular relates to an abnormal roller connection device for a rolling mill. Background Art
[0002] The cold rolling CVC continuous rolling mill is characterized by high production speed, good continuity, high product precision, and a high degree of automatic control. Under the high-paced production tasks, the frequency of roll changing of the rolling mill is also relatively high. As an indispensable daily operation for roll changing, the efficient use of the roll changing car and roll changing device is a strong guarantee for the smooth replacement of rolls. At present, when the roll changing car trolley pulls out the roll, the hook head is hung on the roll head, and the trolley moves longitudinally to realize the roll pulling. As the roll wears out and the replacement frequency is high, the roll seat, roll head, copper slide plate and roll changing car track are also worn, resulting in reduced precision. During the roll changing process, the roll changing car and the frame track are not level, and the friction between the roll seat and the track increases, causing jamming and roll loss.
[0003] In the existing technology, the operation of roll changing requires the cooperation of two people. One person climbs onto the roll changing car and manually holds the hook with an iron rod, and the other person operates the roll changing car to pull it out and replace the new roll. If the rolling mill encounters steel piling, roll meat falling off, or the roll and roll seat are locked, the force of the roll changing car hook locking the roll head cannot withstand the force of the car pulling the roll, and the car hanging groove and the roll head are usually disengaged and it is difficult to pull it out. Solution: Use fire water to continuously spray water on the locked roll seat to quickly cool down the roll. After the temperature of the roll drops, one person climbs onto the roll changing car and manually ties the roll head and roll seat with a wire rope to connect them to the hook head of the roll changing trolley. Another person operates the roll changing trolley to pull out the roll and replace it with a new one. In addition, the cold rolling mill mainly uses emulsion lubrication, so the equipment is covered with lubricating fluid and sludge. The operator climbs onto the roll changing car and stands on the roll seat. This process can easily cause slipping and injury, which brings many obstacles to the normal operation process of the roll changing, prolongs the roll changing time, delays the production rhythm and causes economic losses, and also increases safety hazards such as climbing and slipping, squeezing, and burns.
[0004] In view of the above factors, a rolling mill abnormal roller connection device is provided, which has a simple structure and can effectively prevent roller loss, roll meat loss, generational steel piling, roll seat locking, etc., and can ensure the safety of personnel and save time in operating the roller connection device. It is used in the periodic replacement of intermediate rollers and working rollers in the field of cold rolling mills. Utility Model Content
