Title:
DIE FOR EXTRUDING ALUMINUM
Document Type and Number:
Japanese Patent JP09024415
Kind Code:
A
Abstract:

To obtain an extruded shape having good surface property in spite of repeating extrusion many times.

In this die for extruding aluminum, a flow guide 6, die main body 1 and packer 7 are arranged along the extruding direction. A radius of R ≤0.2mm is provided in the outlet part 5 of a bearing face 3 which is formed on the die main body 1 and the die main body 1 is in contact with the packer 7 through the adjacent face (end face 8) to the bearing face 3. In this way, because a relief part 7 is not provided, the provision of radius in the outlet part 5 is enabled and extruded products having good shape are obtained. And, because the relief part is not provided, the manufacturing cost of the die is also reduced.
