Uncoiling mechanism for multi-layer metal composite rolling

Abstract

The invention relates to an uncoiling mechanism for multi-layer metal composite rolling, and relates to the field of multi-layer metal composite. The uncoiling mechanism comprises an uncoiling machine, a base plate is arranged on one side of the uncoiling machine, a rotating plate is rotationally connected to the base plate, a first pinch roll and a second pinch roll used in cooperation with the first pinch roll are installed on the rotating plate, and a first driving assembly used for driving the rotating plate to rotate is arranged on the base plate. According to the uncoiling mechanism, the axial direction of the first pinch roll and the axial direction of the second pinch roll are deviated through rotation of the rotating plate, then the advancing direction of a metal sheet can be promoted to be deviated, the purpose of deviation rectification is achieved, and therefore the metal sheet can accurately enter a composite rolling mill to be composited, and the production quality of a composite plate is ensured to a certain extent; and in addition, the uncoiling mechanisms can be symmetrically arranged on the upper side and the lower side of a plate strip, uncoiling is carried out at the same time during composite rolling, and therefore the double-face composite effect can be achieved.

Description

technical field [0001] The present application relates to the field of multilayer metal cladding, in particular to an uncoiling mechanism for multilayer metal cladding rolling. Background technique [0002] Multi-layer metal composite panels are prepared by connecting two or more metals in a liquid or solid state. This method can not only reduce costs, but also obtain physical or chemical properties that a single component metal does not have. The common method for preparing multi-layer metal clad plates is generally the "three-step method" cold-rolling cladding of surface treatment of metal plates, rolling and compounding of multi-layer metal plates by rolls, and annealing treatment. [0003] The existing multi-layer metal plate rolling device generally includes an uncoiling roller, which is used to unwind the cladding material or base material, and the uncoiled cladding material or base material is polished by a grinder and then enters a compound rolling mill for rolling. ...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that although the uncoiling mechanism in the related art can send the cladding material or base material into the composite rolling mill for rolling, the traveling direction of the cladding material or base material is prone to deviate during the traveling process. , resulting in the inaccurate alignment during compounding in the compound rolling mill, so that the produced compound plate needs to be additionally trimmed, which is inconvenient to operate
