り成形を達成することが望ましい。 When pressing a deep-drawn sheet product such as the above-mentioned automobile floor panel, if the pressing is performed in one step, cracks often occur and the process becomes impossible. In this case, the occurrence of cracks can be effectively prevented by dividing the drawing process into two parts, first giving preliminary bending to the thin plate material, and then performing the final drawing process. however,
Since this method requires two steps, which increases production costs, it is desirable to achieve sound deep drawing in one step if possible.

旨とするものである。 The present invention was devised in view of the above, and includes a female mold having a recess for deep drawing, and a thin plate material mounted on the female mold in cooperation with the outer periphery of the recess of the female mold. a blank holder for pinching an outer peripheral portion of the recess; and a pin member protruding from the outer peripheral portion of the recess of the female mold so as to be freely protrusive and retractable in the same direction as the displacement direction of the blank holder, and the thin plate material is a female mold. The thin plate material is configured such that when it is mounted on top of the blank holder and the outer circumferential portion thereof is pinched by the blank holder and the pin member is press-fitted, the thin plate material bends and hangs down within the recess due to its own weight. The gist is a press die for deep drawing.

るように支持されている。 Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the figure, reference numeral 10 is a male mold for press molding, 12 is a female mold that cooperates with the male mold 10, and 14 is a thin plate material to be molded. In the case of the automobile floor panel shown above, the thickness is usually 0.6 It is a steel plate with a thickness of ~1.0mm. 16 is a blank holder for suppressing wrinkles that cooperates with the upper surface of the peripheral part of the female mold 12 to press the peripheral edge of the thin plate material during drawing forming of the thin plate material 14;
Reference numeral 18 denotes a recess within the female mold 12, and deep drawing of the thin plate material 14 is performed by the male mold 10 entering the recess 18. On the upper surface of the female mold 12, a plurality of pin members 20 are supported by springs 22 on the outer side of the recess 18 so as to be vertically retractable.

工程を省き一工程で深絞りを行なうことができる
ので、生産コストを低減し得る利点がある。 In the above configuration, the female die 12 is fixed on the press bolster 24 by a tightening device such as a tightening bolt, and the male die 10 is fixed to the main ram of the double-acting press, for example.
Further, the blank holder 16 is driven by an auxiliary ram. (However, it goes without saying that the structure and format of the press itself are not directly related to the present invention.)
Now, for pressing, the thin plate material 1 is placed on the female die 12.
4 is mounted, the same material is moved to the pin member 20 which protrudes from the upper surface of the female mold 12 by the sufficiently large spring force of the spring 22, as shown in FIG.
It is supported by and curves toward the recess 18 under its own weight. When the blank holder 16 is lowered in this state, the spring 22 is compressed and the pin member 20 is lowered to the upper surface of the female die 12, causing the thin plate material 14 to be lowered.
When the peripheral edge portion of the material 14 is pressed by the blank holder 16, the portion of the material 14 facing the recess 18 is bent downward from the upper surface of the female mold 12, producing an effect similar to that of pre-bending. Therefore, male type 10
By descending into the recess 18, a deep-drawn product of good quality can be obtained without cracking. That is, according to the present invention, deep drawing can be performed in one step without the pre-bending step, which has the advantage of reducing production costs.
