摘要： Problem - To present a small-diameter magnesium base alloy tube and its manufacturing method of long length, high dimensional precision, and excellent mechanical properties.
Solving Means - A raw material 1 of aluminum base alloy is extruded and formed by using a forming pattern comprising an upper pattern 2 having plural through-holes 21 for supplying the raw material into diaphragms of equal angles on the circumference and circular cylindrical protrusions 22 positioned in the center of plural through-holes 21 so as to be surrounded by plural through-holes 21 at the exit side of the through-holes 21, and a lower pattern 3 positioned in the concave portions commonly penetrating at the exit of the plural through-holes 21 of the upper pattern 2, having through-holes 32 for inserting the protrusions of circular circumference of the upper pattern by providing a tube forming gap, positioned in the center of concave portions 31 of the concave portions 31 in the circular columnar shape of the upper pattern 2.

摘要： [Problem] To present a manufacturing apparatus of a plate-like tooth profile member capable of forging and forming in one process by using a closed type die, being hardly accompanied by burrs due to plastic changes in the circumferential direction and in the axial direction of the material of the plate-like tooth profile member.
[Solving Means] Consisting of an upper die 1 and a lower die 2 of closed type, the lower die 2 is composed of a tooth die 21 for forming a tooth portion in a material W of a plate-like tooth profile member, and movable dies 22, 22 movable relatively in a vertical direction to the tooth die 21 disposed at both sides in the axial direction of the material W of the plate-like tooth profile member of the tooth die 21, a first stroke is executed for confining the circumference at both end portions in the axial direction of the material W of the plate-like tooth profile member by the upper die 1 and the movable dies 22, 22, and a second stroke is executed for forming a tooth portion in the material W of the plate-like tooth profile member by the upper die 1 and the tooth die 21.
摘要翻译：本发明提供一种能够通过使用封闭型模具在一个工序中进行锻造和成型的板状齿形构件的制造装置，由于塑料周向和轴向上的塑性变化几乎不伴随着毛刺板状齿廓构件的材料。 [解决方案]由上模1和封闭型下模2构成，下模2由用于在板状齿形构件的材料W中形成齿部的齿模21构成，并且可移动模具22,22相对于沿着设置在齿模21的板状齿形构件的材料W的轴向两侧的齿模21相对移动，执行第一行程以限制周长通过上模1和可动模22,22在板状齿廓构件的材料W的轴向的两个端部处进行第二行程，以在第二行程中形成齿部上模1和齿模21的板状齿形构件。
