Auxiliary coiling device for thick metal strip

Abstract

The invention discloses an auxiliary coiling device for a thick metal strip. A wrapping and clamping belt is wound on a sleeve, the head end of the wrapping and clamping belt is connected with the sleeve, and the rest part of the wrapping and clamping belt is used for wrapping and clamping the strip head of the metal strip, so that the strip head of the metal strip generates friction force to drive the metal strip to be coiled. The auxiliary coiling device is arranged at one side of the sleeve and comprises a swing arm frame with one hinged end, and the free end of the swing arm frame is connected with a first clamping roller; at least one hinged frame is hinged to the swing arm frame, the free end of the hinged frame is connected with a second clamping roller, and the hinged frame is connected with the swing arm frame through a tension spring; the first clamping roller and the second clamping roller abut against each other and are used for winding the rest part of the wrapping and clamping belt. According to the auxiliary coiling device, the friction force generated on the metal strip is large, the coiling thickness is large, the device is especially suitable for coiling thicker or higher-rigidity strips, and the pain point in the industry is solved; and in addition, the problem of a strip head impression is solved, and great loss to strip production caused by cutting off the impressions at two ends of the metal strip is avoided.

Description

technical field [0001] The invention relates to the technical field of metal strip rolling, in particular to a coiling auxiliary device for thick metal strips. Background technique [0002] In the production process of steel and non-ferrous metal strips, especially during rolling, degreasing and finishing, the metal strips must be uncoiled and coiled many times. Before coiling, the head of the metal strip needs to be wound on the sleeve, and then the sleeve is rotated, relying on the friction of the sleeve to the strip to drive the strip to rotate with the sleeve. This process is called coiling. [0003] Rolling up can be realized manually, and the biggest problem of manual rolling up is safety, for manual operation rotating parts, danger always exists. In addition, in the early stage of manual coiling, the metal strip slides on the sleeve, and the winding of the metal strip on the sleeve is loose, lacking tension, so it is easy to bulge in the early stage of coiling, which...

AI Technical Summary

Problems solved by technology

The strip with the head print is long and has both ends. If these two parts are cut off, it will bring significant losses to the production of the strip.

[0004] For thicker or more rigid strips, it is difficult to roll them up either by hand or by a belt coiler. The biggest reason is that the strips are not easy to bend and the bending surface in contact with the sleeve is not large enough. , the strip does not get enough friction, causing slippage
