JPS5861915A - Extrusion forming and simultaneous roll patterning method for aluminum material - Google Patents

Abstract

PURPOSE:To perform extrusion forming and patterning simultaneously, in extrusion forming Al material, by projecting a part of floating die for forming hollow part provided to the inside of a forming die and installing a patterning roll above, below or near the projected part. CONSTITUTION:Molten Al material is put in a cylinder 1 provided with a floating die 3 for forming hollow part at the inside and pressed by an extruding piston 4, and a hollow square metallic bar 6 is extruded by a forming die 2. In this case, a proper length of the front part of the floating die 3 is projected from the die 2 to form a projection 3' unified with the floating die 3. A patterning roll 5 having patterned peripheral face is provided above, below or one side of the projection. Patterning is made simultaneously by this patterning roll 5 on the surface of the hollow square bar 6 extracted continuously from the die 2.

Description

[Detailed Description of the Invention] This invention relates to the development of a method for attaching a handle to extruded aluminum materials with some improvements, and its purpose is to develop a series of processing methods for attaching handles to extracted aluminum materials. This is what I did.

In other words, to explain the drawing as an example, there is a molded tie (2) in front of a conventional aluminum melt container cylinder (1).
In the extraction molding method VC, a wax mold (3) commonly called a noro for blow molding is provided inside the mold, and a piston (4) for extruding cast material is provided inside the cylinder (1). By using this molding method, the front part of the float (3) is made to protrude to an appropriate length, and a protrusion (3)' is provided integrally with the float, and the above and below or on one side of the protrusion can be fitted. (2) The handle attached to the circumferential surface is made by attaching a roll (5) and attaching the handle to the top and bottom of the hollow square bar (6) of an appropriate shape that is continuously extracted. be.

In the present invention, as described above, a hollow metal bar is extracted and molded by the extrusion method, and at the same time, the protruding part of the mold and the handle are formed into a handle between the rolls, and the so-called handle is a bar for building materials.

I L. ) roll patterning is related to the law.

Figure 1 shows the process of forming a hollow rectangular bar material using the molding die (2) and the mold (31 (3)' as shown in Figure 3) and at the same time obtaining a metal bar (6) with a handle.
The manufacturing method shown in Fig. 4 is to obtain a channel metal bar (7) as shown in Fig. 5, and a chi) is placed in front of the forming die.
The channel bar material (8) is tied to the front side of the float mold (3) to make it protrude, and the protruding channel bar material (8) 1 side and handle are the bar material that is extracted and formed between the rolls (5). A channel-shaped bar (7) is obtained by simultaneously attaching a pattern to the bar. It goes without saying that metal materials other than aluminum may be used as the extruded material, and the key point is to use the conventional extraction molding method as described above, modify some parts, and add a roll (5) for the handle. By doing so, it is possible to easily and simply obtain a bar for building materials with a continuous hollow handle.

Claims (1)

[Claims] In the aluminum material extrusion molding method, a part of the mold provided inside the extraction die required for aluminum extrusion [7 molding] for forming the hollow part is extended forward to form the hollow part from the outside extraction die. Make it stick out,
Simultaneous roll patterning for aluminum material extrusion is characterized in that a patterned roll is installed below or around the protruding part to simultaneously pattern the aluminum material that has been extracted and formed. Law.
