Description

Chain making apparatus for ornament

The present invention relates to a decorative file forming apparatus, and more particularly, decorative lines connecting decorative beads are molded by the upper and lower molds, but the upper and lower molds are simultaneously raised to allow the lines to be molded, thereby reducing the decorative lines. The present invention relates to a decorative file forming apparatus for shortening molding time and improving productivity.

In general, decorative lines are used to connect decorative beads in the form of nodes, and decorative beads are widely used in necklaces, dog tags, and the like. These cords are complicated because they form a broken connection between beads.

Conventionally, the cutting grooves are formed in advance at equal intervals on the outer circumferential surface of the decorative string in order to cut the decorative string of the wire form at regular intervals. And decorative beads were formed on the outer circumferential surface of the decorative line, but the decorative beads were placed in each of these cutting grooves. After the decorative beads were formed on the outer circumferential surface of the cord, the trim was vibrated to break these cutting grooves. When the cutting grooves are broken, the decoration line is separated into several strands, and the decoration beads are freely connected in the form of a chain to complete the product.

However, in the past, it took a lot of time to form a cutting groove in the decorative file. The lower mold through which the decorative string passes is fixed, and the upper mold is lifted toward the lower mold, so that the cutting groove is formed in the decorative string so that the cutting groove is not formed while the upper mold is elevated. Therefore, there was a disadvantage such as poor formability of the cutting groove.

The present invention was developed in view of the conventional problems, and an object of the present invention is that the upper mold and the lower mold are simultaneously elevated to the decorative string, thereby reducing the time for forming a cutting groove in the decorative string, thereby reducing the productivity of the decorative string. The present invention provides a decorative file forming apparatus.

In order to achieve the above object, the present invention includes an upper guide block and a lower guide block for supporting the upper mold and the lower mold at the upper and lower portions of the body, and the upper lever and the lower portion pivoted around the hinge at the upper and lower portions of the body. Each lever is provided, the lower end of the upper lever is provided with a cam roller for angularly moving the upper lever in contact with the cam wheel rotated in one direction, and the upper lever and the lower lever are provided with the lower lever when the upper lever is angularly moved. Transfer holes are formed to form a cutting groove in the decorative line by their upper and lower molds while angularly moving in the opposite direction.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view of the present invention decorative molding apparatus, Figure 2a, b is a side cross-sectional view showing an operating state of the present invention molding apparatus. The present invention is provided with a body 10, the upper mold 20 and the lower mold 30 is installed, and one side is provided with a drum 16 is wound with a decorative string (50). The drive pulley 12 rotated by the motor 11 is connected to the driven pulley 14 through the belt 13, and the driven pulley drives the upper and lower molds 20 and 30 through the rotation shaft 15. .

The upper mold 20 and the lower mold 30 are supported to be lifted by being fitted to the upper guide block 21 and the lower guide block 31 provided in front of the body 10. The lower guide block 31 is provided to lift the lower mold pin 36 connected to the lower mold 30, and the upper guide block 21 is provided to lift the upper mold pin 26 connected to the upper mold 20. do. And the outer peripheral surface of these upper, lower mold pins 26, 36 are provided with springs 27, 37, the direction in which the upper, lower molds 20, 30 are separated from each other by these springs 27, 37 Are suppressed.

The upper mold and the lower mold are pressed by the upper lever 22 and the lower lever 32 coupled to the rear of the body 10. The upper lever 22 is provided to be rotated about the hinge 22a of the upper end of the body and the push rod 25 connected to the upper mold pin 26 is provided at the tip of the upper lever 22. The lower end of the upper lever 22 is provided with a cam roller 23 in contact with the cam wheel 40 formed on the outer circumferential surface of the rotation shaft 15. While the cam wheel 40 is rotated, the cam roller 23 is driven along the cam curve formed on the cam wheel 40, and the upper lever 22 is angularly moved about the hinge 22a in the form of the cam curve.

The lower lever 32 is provided at the lower end of the body 10 so as to be pivoted about the hinge 33 and the transmission port 24 formed on the upper lever 22 to be interlocked with the upper lever 22 during the angular movement. A contact opening 34 is provided. And the lower end of the lower lever 32 is provided with a pressing rod (35) connected to the lower mold pin (36), and the front end of each pressing rod (25) (35) is formed into a spherical mold pin (26, 36) Reduce frictional resistance.

When the driving pulley 12 and the driven pulley 14 are rotated by the rotation of the motor 11, the present invention has the rotating shaft 15 rotated in one direction. While the rotating shaft 15 is rotated, the cam wheel 40 formed on its outer circumferential surface is rotated and the upper lever 22 is angularly moved about the hinge 22a through the cam roller 23 in contact with the cam surface.

While the upper lever 22 is angularly moved around the hinge 22a, the push bar 25 provided at the tip thereof presses the upper mold pin 26. The upper mold pin 26 is pressed by the push rod to lower the upper mold 20.

And while the upper lever 22 is angular movement and at the same time the lower lever 32 is angular movement in the opposite direction to the upper lever 22 through the transmission hole 34 in contact with the transmission port 24 thereof. The lower lever 32 is angularly moved around the hinge 33 and the lower mold pin 36 is pressed through the pressing rod 35 provided at the tip thereof. The lower mold pin 36 raises the lower mold 30 so as to contact the upper mold 20.

When the upper mold 20 and the lower mold 30 are lifted at the same time, they meet at the central point between them, and the decorative string 50 intermittently passing between them is pressed to form a cutting groove 51. While the cam wheel 40 is rotated, the upper mold 20 and the lower mold 30 repeatedly move up and down along the cam curve thereof, and the cutting groove 51 is continuously formed in the decorative string 50 intermittently passing between them. do.

3 is a system diagram showing the molding process of the present invention, after the cutting groove 51 is formed successively in the decoration line 50 to form a decoration ball 52 on the outer peripheral surface of the decoration line. Decorative beads are formed in each of the decorative grooves 51, and when the decorative wire 50 is applied to the vibration, these cutting grooves 51 are broken and the decorative beads 52 are connected to the decorative wires 50 to complete the product.

As described above, according to the present invention, since the upper mold and the lower mold are simultaneously raised and lowered toward the decorative string while the cam wheel is rotated, the lifting time is doubled than when only one mold is being lifted. Therefore, the time for forming the cutting grooves on the decorative line is faster, so that the productivity of the decorative bead products connected by the decorative line is improved.
