Device for improving coiling folding mark of stainless steel cold annealing and pickling line and use method of device

Abstract

The invention discloses a device of improving a coiling folding mark of a stainless steel cold annealing and pickling line. The device is characterized in that an auxiliary support which is L-shaped is fixed to an outlet pinch roll support; one end of the auxiliary support is connected and fixed to the outlet pinch roll support and the other end of the auxiliary support is the free end; a corrugated paper roll sleeves a cross rod where the free end of the auxiliary support is located; and the axial direction of the corrugated paper roll is parallel to the axial direction of a coiler mandrel. The use method of the device comprises the following steps: the corrugated paper roll sleeves the auxiliary support, during corrugated paper packing operation, a paper head of the corrugated paper roll is led into space between strip steel and the coiler mandrel, and when the coiler mandrel rotates, corrugated paper packing is completed. The device and method have the following beneficial effects: with the adoption of the device, the corrugated paper packing efficiency can be improved substantially and production line speed reduction in a paper packing process is avoided; and by using the technological improvement, the dependence on manual operation can be reduced in an operation process, and injuries to personnel due to the fact that the personnel are required to stand behind a rotating coiler to operate when an area is narrow can be avoided.

Description

technical field [0001] The invention belongs to the technical field of stainless steel cold rolling, and relates to an auxiliary device for a corrugated paper pad in a coiling area of ​​a stainless steel cold annealing pickling line and a method for using the device. Background technique [0002] When the stainless steel cold annealing and pickling line is coiled at the exit, because the shape accuracy of the reel is not good enough or the head of the strip itself is slightly "upturned", horizontal creases will be generated, which are called coiling creases. Coiling creases have a great impact on the surface quality of strip steel. If the degree is severe, it will not be removed after subsequent grinding, and eventually the material cannot be applied to the high-end panel field. [0003] For coiling crease defects, one method is to place a sleeve outside the reel before the strip is coiled, and wrap the steel sleeve on the steel sleeve when the strip is coiled. The advantag...

Problems solved by technology

[0005] Due to the narrow location of the exit area of ​​the continuous production line, the general personnel stand behind the coiler to carry out the corrugated paper operation. This operation has the following risks: First, the corrugated paper to be inserted is long, and the personnel are not easy to control. The offset of the backing will affect the cushioning effect; second, it is dangerous for personnel to work behind the rotating coiler in a narrow area; third, in order to ensure the safety of the personnel, the process slows down during the whole paper backing process, which is harmful to the The continuous cold annealing and pickling line has a great influence on the process stability, resulting in fluctuations in the mechanical properties of the product
