Abstract

The invention discloses a formation device and method for an in-cavity polyurethane foamed aluminum profile. The device and the method are applied to the processing of a heat-insulated aluminum profile. The formation device comprises an aluminum profile conveying line, a glue supplying device, an U-shaped paper strip forming device and a control device, wherein the U-shaped paper strip forming device comprises an unwinding and winding device, a former and a traction device which are sequentially arranged on a worktable; the former comprises an outer die of which an inner cavity is loudspeaker-shaped, and a core die which is inserted into the outer die; the unwinding and winding device is of a passive damping constant-tension unwinding and winding structure; the traction device can drive a paper belt to be gradually converted into an U-shaped paper strip while running through the former; polyurethane glue A and polyurethane glue B are mixed in a glue injecting head, then flow from a glue injecting port into an U-shaped paper strip groove and finally enter a cavity A to be foamed and solidified to obtain the in-cavity polyurethane foamed aluminum profile. With the adoption of the device and the method, the problem that a gap is formed in a connecting part of the aluminum profile in a strip penetrating method and easily leads to air convection can be solved; the heat insulation effect can be improved; the connecting strength of the aluminum profile can be improved.

Description

technical field [0001] The invention relates to an in-cavity polyurethane foam aluminum profile forming equipment and a forming method, which are used for processing heat-insulating aluminum profiles. Background technique [0002] The function of the aluminum profile of the insulating door and window is mainly for heat insulation. The molding methods include the glue injection method and the threading method. The threading method is to connect the two parts of the aluminum profile with plastic strips to achieve the heat insulation effect. The production steps of threading aluminum profile are to manufacture aluminum profile A, aluminum profile B, threading strip A and threading strip B respectively, and then thread threading strip A and threading strip B into the corresponding dovetail notches of aluminum profile A and aluminum profile B , the threading strip A and the threading strip B are made of plastic, and the pressing and locking points of the aluminum alloy are rolled...
