Embodiment

[0024] Such as figure 2 A method for preventing the cracking of the paint film of the all-aluminum furniture edge banding profile includes the following steps:

[0025] A. Profile extrusion: put the 6060 aluminum alloy ingot in the T4 state into the extrusion die of the extrusion machine for extrusion molding. The extruded aluminum profile is cooled by air cooling. The extrusion machine is 500T single-action positive To the extrusion machine, the extrusion die is a combination die;

[0026] B. Spraying process: The extruded aluminum alloy profiles are dried by an automatic production line. The aluminum alloy profiles travel at a speed of 3m / min, and the air-drying temperature is 105°C. The dried aluminum alloy profiles are sprayed by a manual production line , the sprayed film layer is uniform and the average thickness is about 50 μm, the speed of spraying the aluminum alloy profile shall not exceed 1.2m / min, and the aluminum alloy profile after spraying the film layer is so...

Abstract

The invention belongs to the field of aluminium alloy furniture, and relates to a method for preventing a paint film of an all-aluminium furniture edge sealing profile from cracking. The method comprises profile extruding, a spraying process, a wood grain transferring process and a bending process, wherein the sprayed film layer is limited to be uniform in the spraying process, and the average thickness is about 50 mu m; in the bending process, the aluminium alloy profile which is subjected to the wood grain transferring process is bent through a bending machine; the aluminium alloy profile ispre-treated by pre-heating before being bent; the bending temperature of the aluminium alloy profile is greater than or equal to 85 DEG C; and the problems that a paint film cracking phenomenon appears to affect the attractiveness of a product in an edge sealing and bending process of all aluminium furniture in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of aluminum alloy furniture, and relates to a method for preventing paint film cracking of edge-sealed profiles of all-aluminum furniture. Background technique [0002] With the country's advocacy of green environmental protection, energy conservation and emission reduction, the development momentum of the all-aluminum furniture industry is unstoppable. No matter in terms of economic value, product market competitiveness, energy saving and emission reduction, recyclability, or product experience, all-aluminum furniture with zero formaldehyde content has a very important role and significance in it. All-aluminum homes generally use aluminum profile panels for splicing processing. The aluminum panels are easy to disassemble and assemble without dismantling the panels. Because of its light weight and convenient transportation, it can be transported to different places for repeated use. Aluminum profile panel-type all-a...
