Abstract

PURPOSE:To manufacture highly accurate rings of glasses with high efficiency by pressure holding ring blank material of specified size by a spherical die, and after forming the formed ring blank material by rotating and shifting the die, releasing pressure holding and expanding the material. CONSTITUTION:A spherical die 4 consisting of dies 5, 6 for forming upper and lower rings is attached to the shaft 10 of a ring forming machine at a shaft hole 8. The first hydraulic piston P1 is operated and an end 3a of the ring material formed to specified size is held by a rod 14 at the projection of the spherical die 4. A floating roll 15 is lowered by the second hydraulic piston P2, and the shaft is rotated by a motor M while pressing the ring material against the die 4, and shifted by a spiral groove 11 and an engaging pin 12. Consequently, a formed ring material 18 is formed on the die 4. Pressing and holding is released and the material is expanded. If necessary, the expanded ring material 19 is pressed by a press die, and rings for glasses are obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for manufacturing a spectacle ring.

Conventionally, when molding eyeglass rings of various shapes, a lead plate is bent into a bead-shaped outer shape, the eyeglass ring element, i', and A are held with pliers, and the ring X1lJ is pressed into an F shape with the fingers (=
A manual compression molding method was used, in which the material was rolled while twisting. As a result of many years of intensive research, the inventor of the present invention devised a device for forming metal rings in eyeglasses for the first time, as disclosed in Publication of Utility Model Publication No. 56-3'4883.
Nearly 1,000 of these devices are already in use by various eyeglass manufacturers, including Fukui Jiroku, and it is well known that this device has brought about the dramatic progress in the manufacture of eyeglass rings that we see today.

By the way, the applicant of the present application previously submitted a practical application nP+ 57601965 for the special El type used in the mechanical device described in OfJ.
Although filed as Patent No. 3', the present invention aims at a manufacturing method that can be said to be the culmination of these technologies, as well as an automated manufacturing device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The method and apparatus for manufacturing a spectacle ring according to the present invention will be explained below based on the drawings. ? M [+] ("J-shaped glasses ring material (2)
The first step is to cut it into 3+)) pieces. This is because if it is cut after molding, the dimensions will be uneven.

On the other hand, an upper mold (4) for molding eyeglass rings combines a mold (5) for molding an upper ring and a mold (6) for molding a lower ring, and is connected together with a connecting bolt (7). 8) is a shaft hole, and the mold (5) for molding the upper ring has a protrusion (9).

The mechanical device for irregularly shaped eyeglass rings is as shown in Fig. 2, but one shaft (10) passes through the ring in the horizontal direction.

(3+)) When the grip on one end (3a) is released, the cutting element (sill) expands by 1 from (+18) to (+V+) as shown in Figure 4.This expansion process is the main This is the fifth step of the invention.

However, as shown in Figure 4 (1;)), there is still some wear between the one end (32+) and the dragon end (3b), and the fifth nail 1 is shortened.
As shown in the diagram, it is necessary to form a spectacle ring frame (finally convex arc shape j2+i) that suppresses the lens. FIG. 6 shows a press mold used when such a need arises. Upper and lower circles, i'1st J1. It consists of (20 (2■), a medium-heat mouth-like female mold (A), and a shaft-shaped mold (C).

A central hole (C) @ (C) is drilled in the center for a single sleeve type (C) to be overlaid with a cover metal.

When using the upper round button # Place the first expansion molded ring material from the fifth step on the white part of (A), fit the shaft mold ■ into the center hole (A) of the upper conical male mold @I), and fit the shaft mold ■ into the center hole (A) of the upper conical male mold @I). C) is pressed to produce a convex arc-shaped eyeglass ring frame (20) as shown in Fig. 5, and this step is the sixth step of the present invention.The eyeglass ring frame is for left eye and For the right eye, the convex arc shape of the object is −
Since it is necessary to press the other eyeglass ring frame, the force of the lower circle button #li type (a) is used.

That is, the method of the present invention has the structure as described above, and the mechanical device used to carry out the manufacturing method in the second, third, and fourth steps is as shown in FIG. Therefore, this device is equipped with a rotation mechanism, a shift mechanism, and a gripping mechanism on the negative axis side, and an E attachment mechanism on the other axis side to automate these operations.

Therefore, production efficiency has improved, product precision has improved, and defective rates have been eliminated. It should be noted that the mechanical device shown in FIG. 2 is just one example, and the control mechanism, panel panel, motor drive, etc. can be changed as required.
