Equipment for laying, welding and cutting aluminum foils on surface of cylindrical core die

Abstract

The invention discloses equipment for laying welding and cutting aluminum foils on the surface of a cylindrical core die. The equipment comprises an operating platform, wherein an aluminum foil frame mechanism, a guide mechanism, a core die bracket mechanism and an ultrasonic welding mechanism are sequentially arranged on the operating platform along the conveying direction of the aluminum foils. Continuous rolling-over of a roll-over stand in the core die bracket mechanism realizes that the aluminum foils are coated on the surface of the core die, a strip pressure plate fixed on the roll-over stand rolls over synchronously with the roll-over stand, and the aluminum foils are seamlessly wrapped on the surface of the core die during the rotation of the whole die core. The equipment smoothly and uniformly coats the aluminum foils with small thickness on the surface of the core die, so as to obtain composite material circular tubes with aluminum foil inner liners.

Description

technical field [0001] The invention belongs to a device for laying, welding and cutting wide sheets on the surface of a mold, in particular to a device for laying, welding and cutting aluminum foil on the surface of a cylindrical core mold. Background technique [0002] At present, with the rapid development of various composite material products, the anti-corrosion technology of the inner wall of the composite material round pipe has become more and more extensive. Among them, the use of small-thickness aluminum foil as the inner wall layer for anticorrosion can greatly reduce the production cost of the process, but how to better attach the aluminum foil to the inner wall of the composite round tube is an urgent problem to be solved. Since the thickness of the aluminum foil is generally relatively thin, mostly below 0.1 mm, the axial dimension of the mandrel is relatively long, mostly above 1 meter. When the aluminum foil is placed on the surface of the mandrel, the tensi...

AI Technical Summary

Problems solved by technology

When laying aluminum foil on the surface of the mandrel, if the tension is too high, the aluminum foil may be torn; if the tension is too small, the aluminum foil cannot be tightly wrapped on the surface of the mandrel, and it is difficult to cut it straight after welding. and crop thoroughly
