本発明は三次元形状の成形面を有する絞り加工用プレス
金型の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a press die for drawing having a three-dimensional forming surface.
（従来技術）
従来、大型の絞り加工用プレス金型は鋳物から削り出し
にて製作さｎるのが一般的であった。(Prior Art) Conventionally, large press molds for drawing have generally been manufactured by machining from castings.
しかるに、鋳物は、通常大型化する程寸法精叶が出難く

ため大型のプレス金型の製作には多くの加工時間を要し
ていｆｃ。また上型（ポンチ側）と下型（ダイス側）は
それぞれ別体で製作さｎるため、その型合わせにも多く

題に加え、加工そのものが非常に困難となって、より多
くの加工工数や高価な設備を必要とすることとなり、製
造コストは一層増大せざるを得なかった。However, the larger the casting size, the more difficult it is to achieve precise dimensions, and it is unavoidable to take a large amount of machining allowance.For this reason, it takes a lot of machining time to manufacture large press molds. . Furthermore, since the upper mold (punch side) and lower mold (die side) are manufactured separately, there is a problem in that a large number of finishing steps are required to match the molds. In particular, in the case of press molds that have a three-dimensional molding surface, in addition to the above-mentioned problems, the processing itself becomes extremely difficult, requiring more processing man-hours and expensive equipment. Manufacturing costs had to increase further.
（発明の目的］

する。(Objective of the Invention) The present invention addresses the above-mentioned problems of the prior art, and eliminates the use of castings in forming press dies for drawing and press dies for bending having three-dimensional forming surfaces. It is also an object of the present invention to obtain a complete method for manufacturing a press die that can reduce manufacturing costs as much as possible by converting a three-dimensional shape into a two-dimensional shape.

One of the divided thin steel plates is assembled and fixed on the punch side and the other on the die side to obtain an approximate three-dimensional shape forming surface, and then the approximate three-dimensional shape forming surface is polished and finished to form a predetermined three-dimensional shape forming surface. This is achieved by a method for manufacturing a press mold that obtains the following.

った。(Effects of the Invention) As described above in detail, the method for manufacturing a press mold according to the present invention involves three-dimensional shape forming in order to form a press mold for drawing having a three-dimensional shaped forming surface. This method realizes a method of converting a surface into multiple two-dimensional shapes, performing all the processing, and then combining them collectively to obtain an integrated press mold. This makes it possible to improve mold matching accuracy, eliminates the use of castings, and eliminates the cutting of complex and difficult three-dimensional shapes, which significantly reduces the manufacturing cost of press molds. In addition, the degree of freedom in selecting the mold material has been greatly increased compared to the conventional method.
