Problems solved by technology

However, in the existing crimping equipment, the reel uniformly adopts the structure of the hydraulic guide rod. Due to the limitation of the processing, installation and use conditions of the hydraulic guide rod, it is easy to cause oil leakage at the jaws and the clamping of the jaws. Production activities cause a lot of inconvenience

Abstract

A flexible jaw swing arm non-expansion drum device belongs to the technical field of rolling mills. A jaw power plant is articulated on a support of the jaw power plant at one side of a winding drum (11) by a pin shaft c (14) passing through a hydraulic cylinder (13); a jaw locating device is arranged as a bow block (4); the top at the upper end of the bow block is provided with a flexible jaw board (6) which is fixed by a bolt b (7); a fixed jaw board (8) is fixed at the upper end of the winding drum by a bolt c (9) and is positioned at the position corresponding to the flexible jaw board; the bottom at the lower end of the bow block is articulated on the a support of the jaw locating device at the other side of the winding drum by a pin shaft a (3); and the piston rod end of the hydraulic cylinder is connected with the upper end of the bow block by a connector (10). In the invention, according to practical production requirements, the pressure of the hydraulic cylinder is adjusted so as to change the clamping force of the jaw; and by the movement of the piston of the hydraulic cylinder, the opening and closing of the flexible jaw board and the fixed jaw board are realized, thus completely solving the problem of oil leakage at the jaw of the winding drum.

Description

technical field [0001] The invention belongs to the technical field of rolling mills, in particular to a cold-rolling unit and a tension coiler in a finishing unit such as pickling, annealing, shearing and coating of a coil barrel device. Background technique [0002] When working in the cold rolling unit and the finishing unit such as pickling, annealing, shearing and coating of the coil, it is usually necessary to complete the transportation, feeding, rolling, coiling, unloading and weighing of the coil. , forming a continuous operation process. [0003] In the process of rolling the strip, this type of tension coiler is not only used for coiling, but sometimes it is also used to complete the uncoiling work; and relying on this type of tension coiler can establish the front and rear tension of the strip, which can reduce the rolling Control pressure, improve the rolling stability of the roll. However, in the existing crimping equipment, the reel uniformly adopts the str...
