る。Prior art and its problems Immediately after extrusion molding, an aluminum product is placed on a conveying device such as a roller table from its front end, and is transported forward for subsequent processing. Therefore, immediately after extrusion, when the surface is still soft, it comes into contact with a roller table or the like, causing scratches or stains on the surface. As a result, not only does the product look unsightly, but when this product is used in a special device, the performance of the device may also be degraded.
For example, when an aluminum product is used while looking into the vacuum section of a vacuum device, if the surface that looks into the vacuum section has flaws or dirt, it may cause a decrease in the degree of vacuum inside the vacuum section. Become.

はずすことはできなかつた。 Therefore, conventionally, in order to prevent contact scratches or stains on the required surface of the aluminum product from contact with the conveyance device such as a roller table, the aluminum product and the required surface of the same product were floated so that they did not come into contact with the conveyance device during transportation. An aluminum profile consisting of a scratch/stain prevention member that supports the aluminum profile is integrally extruded from a single extrusion opening that includes portions corresponding to both components.
After extrusion molding, post-treatments such as cutting and heat treatment were performed, and then the scratch/stain-preventing member was separated. Then, in order to separate the scratch/stain prevention member from the aluminum product, a thin part is formed between the aluminum product and the scratch/stain prevention member during extrusion molding, and the prevention member is broken off at this thin part. They were separated by cutting or cutting. However,
In order to form a thin-walled portion during extrusion molding, it is necessary to complicate the shape of the extrusion opening of the die, which poses a problem in that the die manufacturing operation becomes difficult.
Moreover, the overall shape of the molded material extruded from one extrusion opening becomes complicated, making it difficult to manufacture the molded material. In addition, there is an upper limit to the properties of extrusion molding when reducing the thickness of the thin section.
It was not possible to easily remove the scratch/stain prevention member from the aluminum product.

を特徴とするものである。Means for Solving the Problems The method of manufacturing an aluminum profile with a removable scratch/stain prevention member according to the present invention is such that the aluminum product and the required surfaces of the product being transported are suspended so that they do not come into contact with the transport device. and the scratch/stain prevention member that supports it are extruded from separate extrusion openings, and immediately after extrusion, they are moved forward so as to approach each other, and the surfaces to be joined to each other are heated to a temperature of 490 to 550. It is characterized in that they are brought into close contact with each other while being maintained at a temperature of °C, and are separably joined.

者を接合したさいの接合強度が小さくなつて疵・
汚れ防止部材の分離が容易になるからである。 In the above, it is preferable that the angle between the surfaces to be joined when the aluminum product and the scratch/stain prevention member come into contact is selected within the range of 3 to 10 degrees. The reason for this is that if the above angle is less than 3 degrees, there is a risk that there will not be enough force to bring the surfaces of the aluminum product and the scratch/stain prevention member into close contact with each other, and the bonding between the two will fail. This is because if the amount is exceeded, the two may repel each other and the bonding may not be successful.
In addition, the temperature of the surfaces to be joined to each other of the aluminum product and the scratch/stain prevention member immediately after extrusion molding is
The reason why we limited it to 490 to 550℃ is because if the above temperature is less than 490℃, the subsequent bonding between the two will not be successful.
This is because if the temperature exceeds 550°C, the bonding strength between the two is not so high that it becomes impossible to easily separate the two after bonding. Furthermore, it is preferable to perform the above operations in the atmosphere. If the process is carried out in the atmosphere, a slight oxide film will be formed on the joint surfaces of the aluminum product and the scratch/stain prevention member, which will reduce the bonding strength when joining the two, resulting in scratches and stains.
This is because the stain prevention member can be easily separated.
