Abstract

PURPOSE: A manufacturing method of high accuracy ring having a non-casting eccentricity through-hole is provided to obtain an effect of increasing the feeling of convexity with improved wearability by controlling the size of ring at an uncut portion. CONSTITUTION: A manufacturing method of high accuracy ring comprises the following steps. A pipe-shaped unbalance jig (100) is formed. The unbalance jig has two concentric circles (C1, C2) having different inside diameter (d) and external diameter (D). An eccentricity (H) is formed that the inside diameter is biased toward a side to the external diameter. One end of the unbalance jig is geared with a fixing chuck of a common lathe. The other end of the unbalance jig is inserted with a precious metal ring (200). When the fixing chuck of the common lathe rotates, the unbalance jig is eccentricity-rotated. A cutting bite formed on a bed of the common lathe repeatedly cuts a side of the precious metal ring which is inserted into the external periphery of the unbalance jig. The circumference circular form (210) of the ring is formed in a way that one side is thicker, and the other side is thinner than a through hole (220) inserted to a finger. A first manufactured ring using the unbalance jig is inserted into a balance jig having an inside and an external diameter of the same concentric circle, which makes it possible to draw a cutting line of a wanted part. An uncut side is used for controlling the size of the ring. [Reference numerals] (AA) Rotation; (BB) Cutting bite; (CC) Rotation shaft

Method for manufacturing high precision ring with non-cast eccentric through hole

The present invention relates to a ring size, eccentric processing and a method of manufacturing a mechanical ring that is easy to adjust the outer circumference cutting line, the conventional mechanical ring size is cut by 360 ° when cutting a line with a diamond using a lathe In the present invention, after adjusting the inner and outer diameters of the ring according to the degree of eccentricity using an unbalance jig, the cutting line can be drawn as much as desired by using a balanced balance. By allowing the size of the ring to be adjusted, the upper part of the ring can be made thicker and the lower part of the ring can be made thin. It relates to a manufacturing method of.

Therefore, the ring of the present invention allows for quick and easy cutting of the eccentric through hole (hollow pinned to the finger) of the ring-type ring by using a universal lathe, as well as a seat groove (angular part or obfuscated hole formed on the outer surface of the ring). ) And side decoration pattern (cutting line) are processed by NC (machining center) machine tool, which is a separate vertical reciprocating cutting device, to significantly improve ring manufacturing (manufacturing time) compared to the conventional casting ring manufacturing method. Reduction) and precision (sophistication) and productivity is characterized in that it is greatly improved.

In general, a ring is a kind of ornament made of precious metals such as gold, silver, platinum, iridium, etc., which are stable in the air and are not easily rusted and have beautiful luster.

These rings are largely divided into casting rings and mechanical rings according to the manufacturing method. The conventional casting rings are manufactured by pouring a casting into a mold, so that the ring shape of the ring does not come out and the machine cut using the lathe is caused due to the bubble generation problem. A situation that cannot be planned continues.

In addition, a conventional mechanical ring is obtained by stretching a plate to obtain a ring shape by pressing, and then turning it over (banding) to make a ring shape, or cutting the length of the ring through wire rod work, winding it in the shape of a ring, and then attaching it with solder. Refers to the ring made by line work or cutting after making raw materials.

However, the conventional mechanical ring was cut to 360 ° when cutting a line using a lathe, so it was not possible to adjust the size and solved the bubble generation problem compared to the cast ring. As a result of the hassle, productivity has been deteriorated, as well as the problem of difficult precision processing of the ring has been continued.

Accordingly, the conventional ring is formed to form a predetermined hollow portion 2 on one inner circumferential surface of the ring 1 to reduce material and weight, as shown in FIG. 5 as a manufacturing method of one embodiment.

When the hollow ring 1 is worn on the wearer's finger in a state in which the hollow part 2 is open, the wearing state is very inconvenient, and various foreign substances may flow into the hollow part 2. In addition, since the appearance beauty is deteriorated, the auxiliary body 3 through which a predetermined pattern is formed is fixed by welding.

In order to manufacture such a hollow ring (1), as shown in Figure 6 in the above-described lost wax casting manufacturing method, a model (silver material) and a predetermined pattern of the ring (2) in which the hollow part 2 is formed After separately manufacturing the model (silver material) of the formed auxiliary body 3, each rubber frame is made using each model of the ring 2 and the auxiliary body 3, and then wax is injected into it. Each wax figure of the ring (2) and the auxiliary body (3) is taken out, and each such wax figure is placed in a flask, and then the plaster is buried and cured. The cured gypsum is heated to dissolve and remove each wax model to complete the gypsum mold. The molten metal is poured in accordance with the casting temperature, and then cooled, and the ring 2 and the predetermined pattern having the hollow part 2 formed thereon are cooled. The formed auxiliary body 3 is manufactured.

Then, the auxiliary body 3 is fixed to the hollow part 2 side of the ring 1 by welding, and the finished part is finished after finishing finishing the welded part to finish the product. do.

That is, in the conventional hollow ring manufacturing method, as described above, each model of the ring (2) and the auxiliary body (3) must be manufactured separately, and correspondingly, the rubber frame must be manufactured separately, and also made of precious metals. The manufactured ring (2) and the auxiliary body (3) should be fixed by welding, and a separate finishing process according to such welding is required.

Accordingly, the manufacturing process is very cumbersome, the material cost and equipment are very large, the welding work is very difficult, and the finishing of the welded part is very cumbersome.

In addition, the work takes a lot of time, the failure rate is very high, and this has the disadvantage that the productivity is very low.

The present invention is to solve the above-mentioned problems, the technical gist of the circumferential surface of the ring-shaped ring using a universal lathe quickly and easily cutting process as well as the position formed on the outer peripheral surface of the ring Compared to the conventional method of manufacturing a cast ring, the groove (the corner or the nest where the gem is placed) and the side decoration pattern (cutting line) are molded by a separate vertical reciprocating cutting machine (NC) machine tool. It is an object of the present invention to provide a method for manufacturing a high precision ring having a non-cast eccentric through which is characterized by a markedly improved ring manufacturing ability (shortening of manufacturing time), precision (fineness) and productivity.

Therefore, the ring manufacturing method of the present invention is to be able to easily adjust the ring size and eccentric processing and the outer circumference cutting line, the conventional mechanical ring is drawn to 360 ° when cutting the line with a diamond using a lathe Due to the size adjustment was not possible, the present invention adjusts the inner and outer diameter of the ring according to the degree of eccentricity using an unbalance jig, and then cuts the cutting line as much as desired by using a balanced balance, but not cut. By allowing the size of the ring to be adjusted at the site, the upper part of the ring can be made thicker and the lower part of the ring can be made thinner, so that the feeling of wearing increases and the volume-to-weight ratio is increased more than twice.

In order to achieve the object of the present invention, an unbalanced jig 100 is formed in the form of a pipe tube, and the unbalanced jig is formed such that the inner diameter d and the outer diameter D have different concentric circles C1 and C2. Eccentricity (H) biased to one side with respect to the outer diameter is formed, one end of the unbalance jig 100 is formed to be physically fixed to the fixed chuck of the universal lathe, the other end of the unbalance jig 100 ring-shaped precious metal ring 200 ) And then, when the fixed chuck of the universal shelf is rotated, the unbalanced jig 100 is eccentrically rotated, and the cutting bite formed on the bed of the universal shelf is inserted into the outer circumferential surface of the unbalanced jig 100. Repetitively cutting only a portion of the surface so that one side is formed thick and the other side is formed thinner with respect to the through hole 220, the outer circumference of the ring 210 is fitted to the finger, The ring processed primarily by using the unbalance jig is manufactured to be able to adjust the ring size of the non-cutting surface while allowing the cutting line to be drawn on a desired portion by being fitted in a regular balance jig having concentric circles of inner and outer diameters.

Thus, the unbalance jig 100 is formed with a plurality of dimensional adjusting incision groove 110 on the outer peripheral surface in the longitudinal direction, the incision groove 110 corresponds to the various inner and outer diameter dimensions of the ring-shaped ring 200 by the elastic force and It is desirable to be able to process while being variable.

In addition, the ring 200, the eccentric through-hole processing from the general-purpose shelf is to be formed in the seat groove 212 processing so that the jewel or decoration is seated on the decorative surface 211 of the outer circumferential circle 210, the seat The groove 212 is formed so that circular, square, polygonal or various patterns can be formed by a machining center (NC) machine tool, which is a vertical reciprocating cutting device, and the circumferential direction of the side surface 230 of the ring-shaped ring 200 It is preferable that a plurality of cutting lines 231 divided at equal intervals are formed so that a decorative pattern including a flat pattern or a sanding pattern is selectively formed at each cutting surface 232.

As such, the present invention relates to a method of manufacturing a mechanical ring that is easy to adjust the ring size and the eccentric processing and the outer circumference cutting line, which uses an unbalance jig and adjusts the inner and outer diameters of the ring according to the degree of eccentricity. By cutting the cutting line as much as you want, but by adjusting the size of the ring in the uncut area, the upper part of the ring can be made thicker and the lower part can be made thin, so the feeling of volume increases compared to the weight. It is effective to enlarge more than twice.
