Tooth punching cutter for tooth punching of heat insulating aluminum profile by adopting casting process

Abstract

The invention relates to a tooth punching cutter for a heat insulating aluminum profile and belongs to the field of machining of aluminum profiles, aluminum profile doors and windows and curtain aluminum profiles. The aluminum profile consists of a left side aluminum profile, a polyurethane bar and a right side aluminum profile; the left side aluminum profile is connected with the right side aluminum profile through the polyurethane bar; a tooth punching cutter for tooth punching of the heat insulating aluminum profile by adopting a casting process comprises a guide disc and rolling discs; theguide disc is a sheet-like disc; the outer contour of each rolling disc is in a chain wheel shape; the outer contour of each rolling disc consists of a plurality of tooth tips which are uniformly distributed along the circumference; each tooth tip has a sharp cutting blade; pitches formed by the tooth tips of the rolling disc correspond to the values of intervals L of rolling locking points; an inner hole of each rolling disc and an inner hole of the guide disc are each provided with more than one guide key; the two rolling discs are installed at the two sides of the guide disc in a back-to-back manner; after the aluminum profile is subjected to tooth punching or groove punching treatment by using a rolling disc cutter, the shear strength is increased, energy consumption of equipment is reduced, the manufacturing cost is lowered, the production efficiency is improved, and the rolling disc cutter is simple in structure, easy to implement, small in vibration and low in noise.

Description

technical field [0001] The invention relates to a gear cutting tool for heat-insulating aluminum profiles, which belongs to the fields of aluminum profile processing, aluminum profile door and window processing and curtain wall aluminum profile processing.

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 two-component polyurethane is poured at the pouring slot by the glue injection machine. 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 combination of the aluminum profile and the polyurethane. Strength, and then cut off the connection 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.
