c indicates the third-stage chamfering device, and 26d indicates the fourth-stage chamfering device. Such a chamfering device has a shaft 5
As the workpiece is sent forward, it is sequentially activated by signals from a workpiece position detector 36, such as a limit switch, installed in parallel with the movable blade 27 in the control unit 1, so that the workpiece edge line forms an arc. In this method, the outer surface of the workpiece is cut to form the workpiece into a deformed octahedron.

The mounting position of the detector 36 is shown in FIGS. 3 and 4, and the reference numeral 37 in the figure indicates that the actuating lever 38 of the detector is attached to the shaft 5 side and moves together with the shaft 5. This is the detected member that comes into contact with and separates from the object.

After the chamfering device as described above, the shaft 5
A dividing cutter 39 for dividing the chamfered workpiece into a plurality of pieces along the longitudinal direction of the workpiece is disposed at the advancing end of the cutter 39 . The split cutter 39 has a workpiece centering blade 40 on the central axis of the shaft 5. This coring blade is formed into a rectangular cylinder shape, and four divided blades 41 are attached radially on the outside thereof. This dividing cutter 39 is designed so that when the workpiece is held by the shaft 5 and moves forward, a rectangular cylindrical core cutting blade 40 hollows out the center of the workpiece, and an outer dividing blade 42 divides the workpiece into four equal parts. The blades are attached to the frame 43 with their respective cutting edges facing in the direction in which the workpiece is fed out. The shaft 5 is configured so that when the workpiece is divided by the dividing cutter 39, it stops moving forward and retreats to its original position.

[Function] Next, the function of this device will be explained. First, when the start switch 23 is pressed, the work holder 11 in the standby position grabs the work W and sends the work to a centering position on the central axis of the shaft 5. At this time, both front and back ends of the workpiece are cut off by the both-end cutting cutter 12. Subsequently, the shaft 5 projects horizontally from within the shaft guide 9 toward the workpiece. The work holding pin 6 at the tip of the shaft pierces and holds the work, and at the same time the work holder 11 opens. The workpiece is advanced by the shaft 5, the upper surface of the workpiece is cut off by a cutting cutter 24, and the workpiece is fed into the forming section 3. The workpiece moves forward while being supported by the shaft 5, and at the processing position, four sets of chamfering devices 26 cut and form the workpiece into an octahedron having an arcuate edge line. This chamfering situation is shown step by step as shown in Fig. 13 A to D.

When the workpiece is chamfered as described above, the workpiece is then pushed into the dividing cutter 39 arranged at the advancing end of the shaft 5. As shown in FIG. 13E, the dividing cutter 39 cuts out the core of the workpiece with a core cutting blade 41 and at the same time cuts the workpiece into four equal parts with a radial dividing blade 42.
When the work is divided, the divided work is discharged into a tray 8 provided at the bottom of the machine as shown in FIG. At this point, the forward movement of the shaft 5 is stopped, and then it is retreated to its original position to complete the forming operation.

[Effects of the Invention] As explained above, according to the molding machine of the present invention,
The shutters, which were conventionally manufactured and processed by Kotoku by hand, can be efficiently manufactured and processed by automatic machines without manual work. Further, according to the present invention, the finished shape is stable, and the shutter can be quickly formed at a low cost, which is extremely effective in practice.
