The inclined track surface 54 is formed so that the molding surface 2a of the upper mold 2 can move slightly laterally during advancement in order to follow the circumferential locus of the cutting edge of the cutter 11 drawn by the rotation of the shell spinner 8. relief raceway surface 54'
is formed. In addition, the opening/closing roller 4 of the upper mold 2
In a pair of guide rails 5 and 6 installed in parallel to open and close the upper mold 2 while guiding the
As shown in the figure, one of the guide rails 5 located on the side of the upper mold relief feeding means 47 is connected to the upper mold guide member 4.
This is interrupted at the attachment point 9, and the guide function is performed by the inclined track surface 54 of the upper die guide member 49, and the other guide rail 6 is
The opening/closing roller 4 is located between the inclined track surface 54 and the opening/closing roller 4.
A rail portion facing the inclined track surface 54 is formed in substantially the same shape as the inclined track surface 54 so that the cutter 11 can roll and move slightly laterally in accordance with the circumferential locus of the cutting edge of the cutter 11. and are installed parallel to each other.

In the above configuration, each shell spinner 8 rotates around the shaft 15 as the turntable D rotates. Meanwhile, in synchronization with the rotation of the turntable D, the mold A is transferred to the conveyor chain B.
Just before the mold A approaches the turning trajectory of the shell spinner 8, the opening/closing roller 4 of the upper mold 2 is moved by a pair of guide rails 5, 26. The upper mold 2 is released from the lower mold 1 while being guided by a distance of 6, and the mold A moves straight in this state.

Next, the molding surface 2 of the upper mold 2 of the mold A that can run straight
In a, the cutter 1 of the rotating shell spinner 8
At the time when the first cutting edge comes into contact, the die A moves straight ahead and performs the following escape feed operation.

The guide rollers 37 of the lower die escape feed means 31 and the lower die pressing biasing means 3 are attached to wear strips 27 and 29 attached to both ends of the lower die 1 that can run straight.
8 pressure rollers 42 roll into contact at the same time. Since the pressure roller 42 is constantly urged in the direction of the arrow Y by the stored force of the compression spring 46 of the lower mold pressing and urging means 38, the lower mold 1 is moved from the position shown in FIG. When moving to the position shown in FIG. 6 and moving further forward, the pressure roller 42 presses and pushes the lower die 1 in the direction of arrow Y while rolling on the protruding raceway surface 28 of the wear strip 27.

Therefore, the concave curved raceway surface 30 of the wear strip 29 attached to the other end of the lower mold 1 advances while being pressed by the guide roller 37 of the lower mold evacuation feeding means 31, so that Following the curved shape of the curved track surface 30, the lower mold 1 moves in a direction transverse to its traveling direction, and the lower mold 1 is ejected.

On the other hand, when the upper mold 2 is in the open state, as shown in FIG. 6 and rolls while being guided between them and advances in the direction of arrow Z, so that the upper die 2 moves laterally along the shape of the inclined track surface 54 and the guide rail 6 facing it. Then, the upper die 2 is ejected.

Therefore, at the time when the cutting edge of the cutter 11 of the rotatable shell spinner 8 comes into contact with the molding surface 2a of the upper mold 2 and draws a circumferential trajectory, it peels off the plate-shaped product C attached to the upper mold molding surface 2a. Then, in accordance with the circumferential locus of the cutting edge of the cutter 11, the lower die 1 and the upper die 2 synchronously escape in the lateral direction while traveling straight, so that the cutting edge of the cutter 11 moves toward the upper die 2. It slides along the molding surface 2a.

The opening/closing roller 4 of the upper die 2 is connected to the inclined track surface 5 of the upper die relief feeding means 47 in FIG.
The cutting edge of the cutter 11 slides along the molding surface of the upper die 2 while rolling on the relief raceway surface 54' from the position of the protruding apex of the cutter 11, but the cutting edge of the cutter 11, which can be rotated, moves along the inclined raceway surface 54'. When a force above a predetermined pressure is applied to the upper die guide member 49, the compression spring 5
1 slides instantaneously in the direction opposite to the direction of arrow maintain. Further, the inclined trajectory of the upper mold guide member 49 is controlled by a long hole 52 formed in the upper mold guide member 49 and a guide shaft 53 fitted into the long hole 52 and screwed onto the fixed support member 48 to protrude. Since the distance between the surface 54 and the opposing guide rail 6 is maintained, the entry of the upper mold opening/closing roller 4 is not obstructed, and the cutting edge of the cutter 11 does not impose any load on the molding surface of the upper mold 2. occurs and only when this load is released, the upper mold guide member 49 moves in the lateral direction to reduce the contact pressure of the cutting edge of the cutter 11 applied to the molding surface of the upper mold 2 and promote a buffering function. It is something.

Incidentally, when the plate-shaped product C adhering to the molding surface 2a of the upper mold 2 is peeled off with the cutter 11 and rolled into the conical cylindrical mold hole 13 of the shell spinner 8, the next shell spinner that can be rotated is formed. 8 is the rear mold A
As the product approaches the product, the same product peeling operation as described above is performed continuously.

As described above, the Ciel Spinner 8 is rotating.
The mold A, which can run straight, approaches each other, and the cutting edge of the cutter 11 attached to the shell spinner 8 comes into sliding contact with the molding surface 2a of the upper mold 2, and peels off the plate-shaped product C attached to this molding surface 2a. At this time, the mold A, which is traveling straight, moves laterally and the molding surface of the upper mold 2 touches the cutter 1.
Since the cutter 1 is retracted along the circumferential locus of the cutting edge of the cutter 1, the cutter 1 is
The contact pressure of the cutting edge 1 is kept uniform over the molding surface of the upper die 2. Therefore, it is possible to reliably and smoothly roll the plate-shaped product C attached to the molding surface 2a of the upper mold 2 into the shell spinner 8 and roll-form it, and also to It exhibits outstanding safety effects, such as avoiding accidents such as damage and breakage of the cutting edge of the cutter 11, and minimizing the causes of failure.
