Description

Working method of automatic roll core sleeve replacing device for cold rolling of steel coil
Technical Field
The invention relates to the field of replacement of a roll core sleeve, in particular to a working method of an automatic replacement device of a roll core sleeve for cold rolling of a steel coil.
Background
When the conventional sleeve is changed on winding core of the winding machine, because the distance between the shaft of the winding core and the ground has a certain height, the winding core often needs a worker to stand above a deep pit, so that the worker is difficult to change the sleeve, and because the deep pit is too high, the worker needs to be very careful when changing the sleeve.
At present, along with the popularization and expansion of the production of ultrathin strip steel such as a cold rolling finishing unit in a steel mill and the like, the replacement of a paper sleeve of a uncoiling and coiling mandrel is more frequent in the production process. Originally, the method of crane lifting, steel coil trolley installation auxiliary supporting plate, manual assistance and the like is adopted for replacement. Taking a coiling machine as an example, because the position of a coiling drum is special, when a mandrel of the coiling machine is separated from the ground by about 1.5 meters and coils a steel plate, a traveling crane is used for lifting a paper sleeve originally, and a worker replacing the paper sleeve needs to stand on the edge of a deep pit with the depth of 5 meters to assist in installing the sleeve
Chinese patent application No.: cn201020117076. x; the pushing and unloading device drives the push plate to move forwards through the driving part, abuts against the end face of the defective winding core through the push plate, and pushes the winding core out of the winding drum, so that the dismounting operation of the winding core is greatly facilitated, and the production efficiency is improved; through setting up the concave arc baffle that can radially adjust, can be applicable to not unidimensional book core and shift out.
Chinese patent application No.: CN 201811115435.5; the utility model discloses a method for replacing a steel coil winding machine core sleeve, which does not need the auxiliary operation of a crane and also saves a special device arranged on a steel coil trolley, and on the other hand, an operator does not need to stand on the edge of a deep pit with the depth of 5 meters but operates on a safety stepping device, thereby being safe and reliable.
Both solutions have the following disadvantages:
1. the first scheme can be taken off the sleeve from rolling up the core, but take off and still need the manual work after rolling up the core and adorn new sleeve on rolling up the core, and the process is too complicated, extravagant workman's a large amount of operating time.
2. The second scheme is through adding safe device of marking time, and the workman of being convenient for changes roll core, reduces workman's construction risk, nevertheless because still need the workman to stand in the top of pit, if safe device of marking time breaks down, the workman still has the risk of falling, and changes the sleeve through the workman, extravagant workman's a large amount of operating time.
