    • PURPOSE:To form a very small quantity of ruggedness on the surface of a material to be worked, by constituting a powder forming metallic mold with a die plate and a ram having an equal coefficient of thermal expansion, and a support plate having a coefficient of thermal expansion different from that of said die plate and ram. CONSTITUTION:The metallic mold for pressing and forming a powder material, etc. is constituted with the die plate 1 having a through-hole 1a, the ram 2 which is inserted into the through-hole 1a and whose tip face is on the same surface as the surface of the die plate 1, and a support plate 3 for supporting at least one of the die plate 1 and the rab 2, in the axial direction of the through-hole 1a. In this case, the coefficients of thermal expansion of the die plate 1 and the ram 2 are made equal, and the coefficient of thermal expansion of the support plate 3 is set to a different value which is larger or smaller than said coefficient of thermal expansion. In accordance with whether the coefficient of thermal expansion of the support plate is large or smaller the coefficient of thermal expansion of the ram, etc., the tip part of the ram 2 is recessed from the surface of the die plate 1 or projected, and a metallic old having the surface on which the ruggedness of about 200mum is formed can be manufactured.
    • 目的:通过用具有相同热膨胀系数的模板和具有相同热膨胀系数的冲头构成具有粉末形成金属模的方法,在待加工材料的表面上形成非常少量的粗糙度,以及具有系数 热膨胀不同于所述模板和压头的热膨胀。 构成:用于挤压和形成粉末材料的金属模具等由具有通孔1a的模板1构成,插入到通孔1a中的冲头2的尖端面在同一表面上 作为模板1的表面,以及用于在通孔1a的轴向上支撑模板1和拉子2中的至少一个的支撑板3。 在这种情况下,使模板1和压头2的热膨胀系数相等,将支撑板3的热膨胀系数设定为比所述热膨胀系数大或小的不同值 。 根据支撑板的热膨胀系数是否大于或等于更小的冲头的热膨胀系数等,冲头2的前端部从模板1的表面凹入或突出,并且 可以制造具有其上形成有约200μm的凹凸的表面的金属旧的。

    • PURPOSE:To simplify the construction of a titled device and to improve the quality of a product by packing powder into a die provided with a large diameter part at the top edge on the inside circumference then compressing the powder after rising once the die. CONSTITUTION:The large diameter part 6 is formed to the top edge of the inside periphery of the die 1 or an adapter 5 is placed on the die 1 and the part 6 is formed thereto. After the die 1 is set to a lower punch 2, the powder is packed into the die 1 and the die 1 is once raised. The powder existing in the large diameter part 6 flows down into the hole of the die 1. An upper punch is thereafter lowered to mold compressively the powder. The density in said part is increased by as much as the larger compression ratio by the above-mentioned method. There is no need for dividing the lower punch to two pieces and the device is simplified. The increase in the density of the required part and the uniformity of the density are made possible and therefore the quality of the product is improved.
    • 目的:为了简化标题装置的构造,通过将粉末包装在设置有内径大的顶部的大直径部位的模具中,通过在模具上升之后将粉末压缩,从而提高产品的质量。 构成:大直径部分6形成在模具1的内周边缘的顶部边缘上,或者适配器5被放置在模具1上并且部件6形成在其上。 在将模具1设置到下冲头2之后,将粉末填充到模具1中,并且模具1一次升高。 存在于大直径部6中的粉末向下流入模具1的孔中。然后将上冲头降低以压缩粉末。 所述部分的密度通过上述方法增加了较大的压缩比。 不需要将下冲头分成两块,简化了设备。 所需部分的密度的增加和密度的均匀性成为可能,因此提高了产品的质量。

    • PROBLEM TO BE SOLVED: To provide an isotropic pressurizing device capable of preventing increase of height while improving production efficiency.SOLUTION: When raising a basket 14 holding a workpiece from a pressure vessel 12, first the basket 14 is uplifted with a lid body 16 in a state connected to the lid body 16 from a storage position at which its entirety is stored in the pressure vessel 12 to a removal position at which its upper end projects from the pressure vessel. At the removal position, connection between the lid body 16 and the basket 14 is terminated, and the lid body 16 moves to an evacuation position deflected in the horizontal direction. In this state, the basket 14 is uplifted to a lift position where completely raised from the pressure vessel 12. When storing the basket 14 in the pressure vessel 12, the storing is performed by an opposite procedure.
    • 要解决的问题:提供一种能够在提高生产效率的同时防止高度增加的各向同性加压装置。解决方案:当从压力容器12抬起保持工件的篮状物14时,首先使筐14被盖体16上升 从其整体存储在压力容器12中的存储位置连接到盖体16的状态到其上端从压力容器突出的去除位置。 在拆卸位置,盖体16与筐体14之间的连接端接,并且盖体16移动到在水平方向上偏转的抽空位置。 在这种状态下,筐14被提升到从压力容器12完全升高的提升位置。当将筐14储存在压力容器12中时,通过相反的过程进行存储。
