specific Embodiment approach 1

[0073] Specific implementation mode one: as Figure 1 to Figure 5 As shown, a method for forming polyurethane foamed metal profiles in the cavity of the strip-threading method is used to produce polyurethane foamed metal profiles in the cavity of the strip-threading method;

[0074] It is characterized in that the molding steps are as follows:

[0075] Step 1, first manufacture profiles A1 and B5 with dovetail notches 8 respectively, and the dovetail notches 8 on the profiles A1 and B5 are symmetrically arranged and arranged longitudinally along the profiles; cut the profiles A1 and B5 into equal length;

[0076] Step 2, use a plastic extruder to produce the threading strip, the upper and lower ends of the threading section have a shape corresponding to the dovetail notch 8, and the middle of the section is a rectangle; cut the threading strip into a threading strip with the same length as the profile A2, wearing strip B4, marking the wearing strip as wearing strip A2, weari...

specific Embodiment approach 2

[0084] Specific implementation mode two: as Figure 1 to Figure 5 As shown, the difference between the second embodiment and the first embodiment is that the profile A1 is fixed, while the glue injection nozzle 3 and the profile B5 move.

[0085] A method for forming polyurethane foamed metal profiles in inner cavity by threading method, which is used for producing polyurethane foamed metal profiles in inner cavity by threading method;

[0086] It is characterized in that the molding steps are as follows:

[0087] Step 1, first manufacture profiles A1 and B5 with dovetail notches 8 respectively, and the dovetail notches 8 on the profiles A1 and B5 are symmetrically arranged and arranged longitudinally along the profiles; cut the profiles A1 and B5 into equal length;

[0088] Step 2, use a plastic extruder to produce the threading strip, the upper and lower ends of the threading section have a shape corresponding to the dovetail notch 8, and the middle of the section is a rec...

specific Embodiment approach 3

[0096] Specific implementation mode three: as Figure 1 to Figure 5 As shown, the molding method of inner-cavity polyurethane foam metal profiles by threading method, the steps also include placing the workpiece in the shaping mold for 2-20 minutes, the ambient temperature of the shaping mold is 10-25°C, and the mixed two-component Polyurethane is foamed and solidified in the cavity surrounded by profile A1, profile B5, threading strip A2, and threading strip B4 to form the space where polyurethane foam strip 7 fills the cavity 13, which plays the role of bonding and increasing strength; Guarantee the relative positions of profile A1, profile B5, threading strip A2, and threading strip B4.

[0097] Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a forming method and forming equipment of a strip-penetrating-method inner cavity polyurethane foaming metal section, which are used for producing the strip-penetrating-method inner cavity polyurethane foaming metal section. The forming method comprises the following steps: firstly, a section A and a section b that are provided with dovetail grooves are manufactured respectively, and a penetrating strip A and a penetrating strip B are manufactured through extrusion and penetrate into the dovetail groove of the section A for forming a U-shaped cavity; a clamping block A and a clamping block B, or self-adhesive films, or self-adhesive sheets are used to seal U-shaped notches in the two ends of the U-shaped cavity, an adhesive supply device is used to inject polyurethane to the U-shaped cavity, and after a polyurethane A adhesive and a polyurethane B adhesive are mixed in an adhesive injection head, a mixture flows out of an adhesive injection mouth and flows into the U-shaped cavity; after standing for 2-20 minutes, polyurethane foaming strips are formed, space of the U-shaped cavity is filled with the polyurethane foaming strips, and the functions of bonding and strength improvement are exerted. One-time combination forming and polyurethane foaming strip on-line casting are realized, the strip-penetrating-method inner cavity polyurethane foaming metal section is formed quickly, the forming method is simple and quick, strip penetrating equipment and technological links are saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method and equipment for forming polyurethane foamed metal profiles in a cavity by a strip-threading method, which are used for producing polyurethane foamed metal profiles in a cavity by a strip-threading method, and belong to the field of building door and window materials. Background technique [0002] The role of aluminum profiles for insulating doors and windows is mainly for heat insulation, and the molding methods include glue injection and strip threading. The threading method is to connect the two parts of the aluminum profile with plastic strips to achieve the effect of heat insulation. 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 th...
