体で押圧する手段が用いられている（特開昭56−9028、
同56−136234、同60−18231）。(Prior Art) Bulge forming means for press-fitting a rubber-like elastic body into the inside of a cup-shaped work housed in a mold is widely known (Japanese Patent Publication Nos. 56-53834 and 59-76628). When this forming means is used to form the mouth or intermediate part of a pipe-shaped work, it is necessary to press the elastic body at the processing position within the work, so a pair of punches are pressed from both sides of the work. And a means for closing one end of the work and pressing the other end with a pressurizing body (Japanese Patent Laid-Open No. 56-9028,
56-136234, 60-18231).

られる。A support block 5 is fixed to the base plate 1 so as to face the mold 2, and the mold 2 side serves as a guide surface 5a for guiding a pressing member described later. Two
A support rod 6 having a head portion 6a is screwed in substantially concentric with. An elastic body seat 7 made of steel, each having a central hole, an elastic body 8 made of rubber, and a punch 9 are sequentially fitted to the support rod 6, and the back surface of the punch 9 is an upward pressure receiving cam surface 9a. Are formed. And a pressing member for pressing the punch 9.
Reference numeral 10 denotes a wedge-shaped downward pressure cam surface 10a and a vertical groove 10b above the support rod 6, and the base plate 1 is mounted on the machine base 11 of the press machine, and the pressure member 9 is Mounted on ram 12.

10aでパンチ９の受動カム面9aを押圧する。As described above, the upper die 4 of the die 2 is united with the lower die 3 by a fixing means (not shown), and the mouth W 1 of the pipe-shaped work W is attached to the die 2.
The ram 12 is inserted into the gap 13 between the inner peripheral surface of the elastic body 8 and the outer peripheral surface of the elastic body 8.
When the pressing member 10 is lowered, the pressing member 10 is lowered along the guide surface 5a with the vertical groove 10a straddling the support rod 6, and the driving cam surface thereof is lowered.
The passive cam surface 9a of the punch 9 is pressed by 10a.

るとワークＷの取出しができる。At this time, the pressure member 10 is wedge-shaped pressed into the space between the guide surface 5a and the passive cam surface 9a, so that the reaction force is supported by the guide surface 5a and a strong thrust acts on the punch 9 to cause the punch 9 to move. Is moved along the support rod 6 to press the elastic body 6 against the elastic body seat 7 to expand the diameter. Due to the diameter expansion, the mouth portion of the work W is pressed against the molding surfaces 3a, 4a inside the mold 2 so that the molding surface 3a,
It is bulged into the shape of 4a. When the ram 12 is raised, the elastic body 8 returns to its original shape, and when the upper die 4 is separated from the lower die 3, the work W can be taken out.

い。The processing of the mouth of the pipe-shaped work W has been described above, but the mouth of a bottomed container can also be machined. Furthermore,
If the distance between the mold 2 and the support block 5 is lengthened and the support rod 6 and the punch 9 are lengthened, it is possible to process the intermediate portion of a straight tubular work. Alternatively, the punch 9 may be directly driven by a hydraulic mechanism, a screw mechanism, or the like without providing a cam surface.
