Description
Technical Field
The utility model relates to a steel production facility, especially a help package before being applicable to the steel sheet and opening flat entering coiling machine.
Background
After being unfolded, the steel plate enters a coiler through a coiling-assistant device, a coiling drum of the coiler provides power, and a pinch roll servo hydraulic cylinder of the coiling-assistant device provides a pressing force. Because the servo hydraulic cylinder is not synchronous or balanced with the pressing force on the two sides of the wrapper pinch rollers, the upper roller of the wrapper device is a single roller, so that creases and waves can appear, the quality defect of a steel coil is caused, the phenomenon of irregular waves appears after a finished product, the quality problem of the product is greatly influenced, and the phenomenon of product return of customers is caused. The phenomenon belongs to the technical defect before the steel coil is formed, and the problem is solved by changing the structure of the coil aid system urgently.
Due to the pressure problem of the rolling assisting device, the irregular wave phenomenon appears after the cold-rolled sheet is curled, and the product quality is directly influenced.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a cold-rolled sheet uncoiling helps a roll device to the not enough of above prior art. The problem of the wave-shaped product defects of the cold-rolled sheet is solved under the condition that the layout of original production line equipment is not changed, and the appearance quality of the cold-rolled sheet product is improved.
The technical proposal of the utility model for solving the technical problem is that: a cold-rolled sheet decoiling and coiling assisting device is characterized in that: comprises a base, a supporting upright post, a lower roller, a front roller assembly, a rear roller assembly and a motor; the motor provides power for the front roller assembly and the rear roller assembly; the lower end of the supporting upright post is fixedly connected with the base, and the lower roller is connected with the base through a roller seat; the front roller assembly comprises a front hydraulic cylinder, a front upper roller arm and a front upper roller, the front end of the front upper roller arm is hinged with the top end of the front hydraulic cylinder, the middle section of the front upper roller arm is rotatably connected with the supporting upright post, and the rear end of the front upper roller arm is connected with the front upper roller through a roller seat; the bottom end of the front hydraulic cylinder is fixedly connected with the base; the rear roller assembly comprises a rear hydraulic cylinder, a rear upper roller arm and a rear upper roller, the front end of the rear upper roller arm is rotatably connected with the support upright post, the middle section of the rear upper roller arm is connected with the rear upper roller through a roller seat, and the rear end of the rear upper roller arm is hinged with the top end of the rear hydraulic cylinder; the bottom end of the rear hydraulic cylinder is fixedly connected with the base; the back upper roll arm is positioned above the front upper roll arm.
The rear upper roller arm is a C-shaped arm, and the front upper roller arm is a straight arm.
