형의 요구가 형성되도록하여 신축성이 양호한 고무관을 삽입하고 그 요구의 입구에 중앙통공이 천공된 마개를 끼운후 구슬본체의 외주면에 동, 금, 은 등의 도금층을 형성시켜 상기 마개를 일체화되게 하므로 요구내의 고무관이 이탈치 못하게 된것인데, 이는 구슬본체내의 고무관보존이 비교적 양호하고 외관이 미려한 등의 효과는 있으나 외경이 아주 작은 2-3mm 이하의 구슬본체를 제조할 경우 상기 구슬본체의 요구경은 1mm 이하가 되므로 이때 요구내에 마개를 끼워 넣기가 매우 어려워 작업능률저하의 요인이 되었으며 특히 이러한 구슬을 이용한 목걸이를 오래 사용되게되면 상호인접구슬들이 자주 부딪쳐 요구측의 얇은 도금층이 부서져 마개가 빠져나올 우려가 많아요구내의 고무관을 확실히 영구보존키 어려웠던 등의 제반결점이 있었다.Currently, the beads of the necklaces used for the same purpose are injection molded of spherical or oval synthetic resin beads as described in the Korean Utility Model Registration No. 36258.

Insert the rubber tube with good elasticity by inserting the rubber tube with good elasticity, insert the stopper with the central hole perforated at the entrance of the request, and form the plating layer of copper, gold, silver etc. on the outer circumferential surface of the bead body so that the cap is integrated. The rubber tube in the request is not detachable, which is effective in preserving the rubber tube in the bead body and having a beautiful appearance. However, when the bead body having a diameter smaller than 2-3 mm is manufactured, the required diameter of the bead body is 1 mm. At this time, it is very difficult to insert the stopper into the request, which is a factor of deterioration of the work efficiency. Especially when the necklace using such beads is used for a long time, mutual adjacent beads frequently collide, and the thin plating layer on the request side may be broken, causing the plug to come out.

Insert the silicone rubber tube 4 into the mold request 2 as shown in FIG. 2B and attach the support rod 6 to the communication hole 7 of the bead body 1, 1a and the communication hole 7a of the silicone rubber tube 4. When inserted into the 2c tile and then injected into the processing apparatus is formed as the support rod 6 is removed from the 2d and 5 degrees, in this case, only the support rod 6 is removed, the rubber tube (4) When the support rod 6 is removed from the rubber tube 4, the rubber tube 4 is slightly soiled by its elasticity, so that the communication hole 7a of the rubber tube 4 is larger than both side communication holes 7 and 7b of the bead body 1, 1a. Since the diameter is slightly narrower when it is inserted into the collar 36 so that it is a little tightly fitted is not able to move by itself.

That is to say from the apparatus for processing the spherical beads as shown in Figs. 3 and 4, first, the bead body 1 in the same state as the 2c diagram is poured into the absorber 12 provided on the upper surface of the stationary disk 8 of the processing apparatus. Power is supplied to the heat transfer heater 10 in the stationary disk 8 to preheat the stationary disk 8 to about 70 ° C.-80 ° C., and then the motor 16 is driven to cause the rotation disk 13 to rotate. The device will be activated.

At this time, the upper and lower intervals of the central processing chamber 11 between the stationary disk 8 and the rotating disk 13 are equal to the diameter of the bead body 1, the interval of which the handle 37 is installed and the thread of the main shaft 9 Two support nuts 20 and 20a screwed together to 21a can be manipulated to accurately adjust, and the driving force of the motor 16 is decelerated to a constant rotational power (for example, 80-120 RPM) by an interlock reducer 17. The rotary disk 13 is rotated through the speed reducer pulley 18-> V belt 19-> rotation disk pulley 15. As shown in FIG.

형 요구(2) 입구선단외연에 돌설된 돌부(3)를 서서히 무르게 만들어주므로 구슬본체(1)는 각 연통공(7)(7a)에 삽입된 지지봉(6)과 아울러 전체적으로 구형상으로 가공이 되게 되며, 일단가공된 구슬본체(1)는 회전원판(13)의 회전시 발생되는 원심력에 의해 점차 밖으로 나아가 최종에는 구슬안내부(21)로 모인 후 구슬안내부(21)의 개폐조절문(22)을 통해 구슬받이용기(23)로 낙하되며 이때 구슬받이용기(23)내에는 자연온도의 냉각수가 유통되게하여 낙하된 구슬본체(1)가 신속히 냉각되게하므로 기 가공된 구형상의 모양을 그대로 유지하면서 굳어지게 된것이며 또한 구슬안내부(21)의 개폐조절문(22)을 넓게하거나 좁게 조절하므로서 구슬본체(1)의 가공체류시간을 조절할 수 있어 구슬본체(1)의 재질이나 직경크기에 구애됨이 없이 다양하게 사용할 수가 있는 것이다.In addition, the rotating disc 13 mounted bearings 14 on the lower surfaces of the upper and lower hollow surfaces to suppress wear between the main shaft 9 and the upper support nut 20. The driven bead main body 1 introduced into the absorber 12 of the apparatus driven as described above is introduced into the central processing chamber 11 along the passage of the fixed disk 8 and rotates at a constant rotational power 13. Rolled round by the heat transfer of the heat transfer heater (10) in the fixed disk (8) of the bead body (1)

Mold request (2) Since the protrusions (3) protruding from the outer edge of the inlet end gradually soften, the bead body (1) is processed into a spherical shape as well as the supporting rod (6) inserted into each communication hole (7) (7a). Once the bead body (1) is processed is gradually moved out by the centrifugal force generated during the rotation of the rotary disk 13 and finally gathered in the bead guide portion 21, the opening and closing control door of the bead guide 21 ( 22) falls through the bead container 23, and at this time, the bead container 23 allows the coolant at a natural temperature to be circulated so that the dropped bead body 1 is rapidly cooled, thus maintaining the pre-processed spherical shape. It is hardened while maintaining, and also by adjusting the opening and closing control door (22) of the bead guide (21) wider or narrower to adjust the processing residence time of the bead body (1) to the material or diameter of the bead body (1) What can be used variously without being particular to be.

Therefore, the support rod 6 may be removed from the bead body 1 after the primary processing, and then the plating layer 5 may be formed or colored on the outer circumferential surface of the bead body 1.

Next, when describing an apparatus for processing elliptical beads like the sixth diagram, since the shape itself is elliptical, it cannot be processed while rolling it uniformly, so productivity is lower than that of the spherical bead processing apparatus, but this is also very quick and accurate compared to the conventional method. It can achieve product uniformity.

That is, the support rod 6 is inserted into the communication hole 7 of the oval bead body la and the communication hole 7a of the rubber tube 4 in the same manner as in the second d degree, and the lower mold is installed in the center of the support die 25. It is inserted into the semi-elliptic request 26 of (24), and the protrusion 3 protruding on the outer edge of the inlet tip of the bead body 1a is positioned to the top surface.

At this time, the heat transfer heater 30 in the upper mold 27 is operated so that the upper mold 27 is maintained at about 70 ° C.-80 ° C., and then presses the handle of the pressing part 31 and presses down the pressing part 31. The upper mold 27 is pressed through the connector 34 so as to compress the spring 29 of both side walls 28, and the semi-elliptic request 26 of the upper mold 27 is bead body 1a. Will be in close contact with the upper side of the.

Therefore, the top surface protrusions 3 of the bead body 1a are deformed in the same manner as the surface of the upper mold 27 by the semi-elliptic request 26 of the upper mold 27 and the heat of 70-80 ° C. Will be. Once the primary processing is finished, the same method as the above-mentioned spherical beads is treated.
