Tooth punching equipment for carrying out tooth punching on heat insulation aluminium section by pouring process

Abstract

The invention discloses tooth punching equipment for carrying out tooth punching on a heat insulation aluminium section by a pouring process, relates to the heat insulation aluminium section, and belongs to the field of aluminium section processing, aluminium section door and window processing and curtain wall aluminium section processing. The aluminium section consists of a left aluminium section, a polyurethane strip and a right aluminium section; the tooth punching equipment for carrying out tool punching on the heat insulation aluminium section by the pouring process comprises a rack, a supporting wheel, left and right guide wheels, an upper pressure wheel, a lower guide roller, a shaft seat, a power source, a spindle, a sliding seat, a guide disk, rolling disks and the like; the rolling disks roll two convex strips on the upper surface of a pouring rabbet; tooth tops of both left and right rolling disks roll triangular grooves or rectangular grooves of the left aluminium section and the right aluminium section; the left and right convex strips are disconnected with the positions of the tooth tops of the rolling disks and the positions of the triangular grooves or the rectangular grooves at the same time so as to form rolled lock points. The rolled lock points increase an adhesive force of the heat insulation polyurethane and aluminium section and improve shearing intensity; the heat insulation aluminium section processed by the tooth punching equipment is a new variety of heat insulation aluminium section; the novel tooth punching equipment is provided.

Description

technical field [0001] The invention relates to a heat-insulating aluminum profile, in particular to a heat-insulating aluminum profile with casting teeth, and belongs to the fields of aluminum profile processing, aluminum profile door and window processing, and curtain wall aluminum profile processing. Background technique [0002] Heat-insulating aluminum profile is a new type of energy-saving building material. It is an aluminum profile composed of non-metallic materials with low thermal conductivity and aluminum alloy connection. It has the functions of heat insulation and cold insulation. The doors, windows and curtain walls made of this have excellent thermal insulation properties. and sound insulation performance. At present, the thermal insulation aluminum profile industry, aluminum profile door and window processing and curtain wall aluminum profile processing industry adopt the method of extruding a complete aluminum profile at one time, and use a gear cutting mach...

AI Technical Summary

Problems solved by technology

At present, the thermal insulation aluminum profile industry, aluminum profile door and window processing and curtain wall aluminum profile processing industry adopt the method of extruding a complete aluminum profile at one time, and use a gear cutting machine to mechanically lock the four locking points in the longitudinal direction (vertical cross-sectional direction) of the aluminum profile. The tool is toothed or grooved, and the pouring equipment is used to pour two-component polyurethane at the pouring groove. After the two-component polyurethane is cured, a polyurethane strip is formed. The polyurethane strip and the aluminum profile are connected together to increase the bonding strength of the aluminum profile and the polyurethane. , and then cut off the connecting strip at the pouring notch of the aluminum profile to reduce the thermal conductivity of the aluminum profile, improve the thermal insulation of the aluminum profile doors and windows, and form a heat-insulating aluminum profile; the main purpose of toothing or slotting is to solve the problem of aluminum profiles and polyurethane The compatibility of the rubber strip is poor, especially the adhesion between fluorocarbon, electrophoresis, plastic spraying, and oxidized aluminum profiles and polyurethane is worse, the bonding strength is low, and the shear strength is low. The problem that affects the mechanical properties and quality of heat-insulating aluminum profiles, in order to solve this problem, mechanical reciprocating knives are usually used to make teeth on the four locking points of the aluminum profile notch, and the compound knives are used on the notch of the aluminum profile Cut and extrude uniform small grooves at the four locking points to increase the shear strength. The mechanical compound movement tool movement mechanism is complicated, the mechanical vibration is large, the noise is large, and the efficiency is low.
