Description

Stripping device {coupling device for strip}

The present invention relates to a connection device for physically connecting the connecting portions of the strip that is continuously moved in the cold rolling and plating process, and more particularly, folded and connected so as to be arranged in a curved surface during winding in a fixed state by one insertion A strip connecting device capable of winding a strip in the form of a roller.

In general, a welding joint method is used to connect a broken strip in which the material is broken in a cutting and rolling process or in a repair operation or a process such as an exchange of a roller in which the strip is wound in a continuous process such as a cold rolling and a plating process. do.

In order to connect the strip using the welding joint method, a straight section for minimizing welding deformation and a supporting section for welding the lower part are required, which is difficult to install in cold rolling and plating processes. By performing welding after moving the generated and divided strips to a place where welding is possible, work due to the movement is delayed, and there is a problem that a lot of time is required according to the welding work.

In particular, during repair work such as roller replacement, thin dummy coils are put in comparison with the strips to facilitate preparation after repair of the strip. As the strip is punched during welding, the welded part is flattened by a hammering operation after hundreds or thousands of spot welding, and taping is performed to prevent the projected part from coming into contact with the replaced roller and being damaged even after flattening. There was a problem that takes a lot of work time and manpower.

As described above, the welding joining method used to connect the strip divided by the cause of roller replacement, cutting, breakage, etc., requires that the welding be carried out after moving to the welded position so that the continuous progress of the process is performed. If the process is difficult and there is a problem, and the welding process causes a thin strip through the rolling mill to be drilled, the welding process should be carried out a plurality of times. There was a problem that a lot of manpower and cost was consumed as it had to be performed.
