Description

TECHNICAL FIELD

[0001] The present application relates to a rolling technique, and in particular, to a rolling device for a ring, which can smoothly and uniformly roll an inner edge portion of the ring while protecting a texture or pattern structure on an outer peripheral portion of the ring. BACKGROUND

[0002] Many ring-shaped objects, such as rings, bracelets, etc., are often molded by casting and then polished to make the appearance more beautiful. However, the ring-shaped objects molded by casting have a loose internal structure and a low density, which results in a low hardness and strength. Such ring-shaped objects are easily damaged or deformed when subjected to external pressure. On the other hand, ring-shaped objects manufactured by forging have a high density, but have a simple appearance or a welded portion that is easily broken.

[0003] Although the stamping technique has been developed to use rubber, acrylic or polyurethane (PU) as the material of the stamping mold, this modified method can effectively increase the density and easily make a concave mold or a convex mold from rubber, acrylic or PU, and can make a relatively complex pattern. However, the pattern is limited to one-time molding, and it is difficult to make a beautiful detail like casting. In addition, rubber or PU as the stamping material is easily cracked, and the metal ring-shaped object has burrs.

[0004] Therefore, there is an urgent need for a manufacturing technique for ring-shaped objects that can take into account the design and structural strength of the ring-shaped objects. SUMMARY

[0005] An object of the present application is to provide a rolling device for a ring, in which an embedding material of a roller tightly covers an outer peripheral portion of the ring, and a hole in the center of the embedding material exposes an inner edge portion of the ring. Thus, in the process of increasing the density of the ring-shaped object by rolling the inner edge portion of the ring with a cylindrical rolling wheel inserted into the hole of the embedding material, the outer peripheral portion of the ring is protected by the embedding material. This not only fixes the ring, but also protects the texture or pattern structure on the outer peripheral portion of the ring. In addition, the roller is circular, and the hole is located at the center of the roller, so the cylindrical rolling wheel can smoothly and uniformly roll the inner edge portion of the ring.

The removable bottom center retaining member 240 can include a smaller diameter cylindrical protrusion 242. The cylindrical protrusion 242 can be used to hold a ring R to be rolled. That is, the ring R can be fitted into the cylindrical protrusion 242 and fall on the top surface of the removable bottom center retaining member 240, and the inner edge RI of the ring R can be placed on the shoulder 241 of the top surface of the removable bottom center retaining member 240. The top surface of the removable bottom center retaining member 240 can be slightly lower than the lower circular frame 220. Figure 2 Figure 3 As shown in Figs. 1 and 2, the ring R can include an outer peripheral portion RO and an inner edge portion RI inside the outer peripheral portion RO. The inner edge portion RI can be placed against the shoulder 241 of the top surface of the removable bottom center retaining member 240, and the outer peripheral portion RO can be outside the top surface of the removable bottom center retaining member 240. ​​

[0029] As shown in Figure 3 After the ring R is fitted over the cylindrical protrusion 242 of the removable bottom central retainer 240, the removable central retainer sleeve 250 can be mated with the removable bottom central retainer 240. Specifically, the removable central retainer sleeve 250 has an inner hole 252 into which the cylindrical protrusion 242 of the removable bottom central retainer 240 can be inserted, and the removable central retainer sleeve 250 is pressed against the inner edge portion RI of the ring R. In some embodiments, a collar 254 is provided on the removable central retainer sleeve 250, which can be used for a tool, such as a screwdriver, to facilitate the removal of the removable central retainer sleeve 250 from the hardened investment 270. The investment 270 can be, for example, a high temperature investment powder (e.g. phosphoric acid or ethyl silicate).

[0030] Please refer to Figure 2 and Figure 3 During construction, the investment 270 can be added in several portions within the circular frames 210 and 220 to secure the removable bottom retainer base 230, the removable bottom central retainer 240, the removable central retainer sleeve 250 and the ring R. After the investment 270 is hardened, the removable bottom retainer base 230, the removable bottom central retainer 240 and the removable central retainer sleeve 250 are removed, leaving a through hole 272 in the investment 270. The peripheral portion RO of the ring R is embedded in the investment 270, while the inner edge portion RI is exposed by the through hole 272 in the investment 270.

[0031] Please refer to Figure 1 , Figure 4 and Figure 5 wherein Figure 4 and Figure 5Fig. 1 shows a schematic diagram of a rolling wheel apparatus 300 according to an embodiment of the present application. The rolling wheel apparatus 300 can include a cylindrical rolling wheel 310, two bearings 320, two bearing inner raceway adapters 330, and two bearing mounting tubes 340. The two bearing inner raceway adapters 330 are respectively disposed in the inner races of the two bearings 320. Each bearing inner raceway adapter 330 has a polygonal socket 332. The two bearings 320 are respectively mounted in the two bearing mounting tubes 340. The side of each bearing mounting tube 340 can be provided with at least one protrusion 342 to facilitate the coupling of the rolling wheel apparatus 300 with a machine 500. The two ends 312 of the cylindrical rolling wheel 310 are polygonal structures corresponding to the shape of the sockets 332 of the bearing inner raceway adapters 330, and can be respectively inserted into the sockets 332 of the two bearing inner raceway adapters 330. The cylindrical rolling wheel 310 is inserted into the perforations 272 of the embedding 270 of the drum 200 and the ring R positioned in the embedding 270 to roll the inner edge portion RI of the ring R in the drum 200. When the rolling wheel apparatus 300 performs a rolling operation, the cylindrical rolling wheel 310 drives the bearing inner raceway adapters 330 to rotate through the polygonal structures of the two ends 312. Since the bearing inner raceway adapters 330 are embedded in the inner races of the bearings 320, the inner races of the bearings 320 can be driven to rotate together, which can effectively reduce the abrasion of the polygonal sockets 332 of the two ends 312 of the cylindrical rolling wheel 310 and the bearing inner raceway adapters 330 due to rotation without shape transformation.

[0032] Please refer to Figure 1 and Figure 6 wherein Figure 6 Fig. 2 shows a schematic diagram of a base 400 according to an embodiment of the present application. The base 400 includes a rolling platform 410 and two tracks 420. The rolling platform 410 has an extension direction ED. The rolling platform 410 can be used for the drum 200 to rotate thereon and roll back and forth along the extension direction ED. The two tracks 420 are respectively located below the opposite sides of the rolling platform 410. The machine 500 of the rolling wheel apparatus 300 can move back and forth along the extension direction ED of the rolling platform 410 on the two tracks 420. The left and right sides of the rolling platform 410 are respectively provided with two elongated blocks 412 arranged along the extension direction ED to limit the rotation of the drum 200. In some embodiments, the front and rear sides of the rolling platform 410 are respectively provided with a baffle 414 and 416 as the boundaries of the front and rear rolling of the drum 200. The opposite ends of each elongated block 412 are respectively engaged with the baffles 414 and 416.

[0033] In Figure 6In the illustrated embodiment, the base 400 includes two support members 430 to stably support the rolling platform 410 for facilitating the rolling operation. Each support member 430 can be provided with two slots 432 and 434 arranged in sequence under the rolling platform 410. The support members 430 of the base 400 can be any structure capable of supporting the rolling cylinder 200 to stably perform the rolling operation thereon, and are not limited to Figure 6 as shown.

[0034] Please refer to Figure 1 and Figure 7 wherein Figure 7 is a schematic diagram of an apparatus of a machine 500 according to an embodiment of the present application. The machine 500 is arranged on the base 400 for the apparatus rolling wheel device 300, and can move along the two tracks 420. The machine 500 can mainly include a support seat 510, a plurality of elastic elements 520, and a rolling portion 530. The support seat 510 is arranged on the tracks 420 of the base 400. In Figure 7 In the illustrated embodiment, the support seat 510 includes four vertical rods 512, two horizontal rods 514, two connecting rods 516, and four wheels 518. Each connecting rod 516 connects two vertical rods 512 located at the same side of the rolling platform 410, and the two horizontal rods 514 are arranged in the two connecting rods 516, wherein the horizontal rods 514 are arranged in the slots 434 of the two support members 430 of the base 400. The four wheels 518 are arranged at the bottom of the vertical rods 512, so that the support seat 510 can move on the tracks 420. The support seat 510 can have any suitable structure, and the present application is not limited thereto.

[0035] The elastic elements 520 are arranged on the vertical rods 512 of the support seat 510, and are located at opposite sides of the rolling platform 410, respectively. The elastic elements 520 can be springs, for example. During the rolling operation, the elastic elements 520 can provide the travel of the operator downward. The rolling portion 530 is arranged on the elastic elements 520 and across the rolling platform 410. For example, as shown in Figure 7 The rolling portion 530 includes two side plates 532 located at opposite sides of the rolling platform 410, and two connecting plates 534 connecting the two side plates 532. The machine 500 can further include a fixing rod 540 arranged in the two side plates 532 of the rolling portion 530, and passing through the slots 432 of the two support members 430 of the base 400 to be located below the rolling platform 410, so as to stabilize the structure of the rolling portion 530.

[0036] The rolling portion 530 further includes two fixing tubes 536 arranged in the two side plates 532 and opposite to each other, so that the two fixing tubes 536 are located at opposite sides of the rolling platform 410, respectively. The fixing tubes 536 can be substantially perpendicular to the extension direction ED of the rolling platform 410. Each fixing tube 536 is provided with at least one slot hole 536a forFigure 4 The protrusion 342 of the bearing mounting tube 340 of the rolling wheel apparatus 300 is inserted, whereby the bearing mounting tube 340 is positioned in the fixing tube 536. In some embodiments, the end of each fixing tube 536 is provided with a threaded structure 536b for locking a nut 538, whereby the bearing mounting tube 340 is fixed in the fixing tube 536.

[0037] Please refer to Figure 2 and Figure 3 During construction, the removable bottom center retainer 240 can be placed above the hole 234 of the removable bottom retainer base 230, and the lower half of the circular frame 220 can be placed on the removable bottom retainer base 230. Next, the ring R is sleeved on the cylindrical protrusion 242 of the removable bottom center retainer 240, and the removable center retainer sleeve 250 is sleeved on the cylindrical protrusion 242 of the removable bottom center retainer 240 and abuts against the inner edge portion RI of the ring R. Then, the liquid of the embedding material 270 is poured into the entire circular frame 220 and covers the outer peripheral portion RO of the ring R. Next, after the embedding material 270 hardens, a separating agent is applied on the surface, and the insertion column 214 of the upper half of the circular frame 210 is inserted into the single-sided insertion hole member 224 of the lower half of the circular frame 220 to butt joint the circular frames 210 and 220. Then, the liquid of the embedding material 270 is poured into the entire circular frame 210 again.

[0038] After the embedding material 270 in the circular frames 210 and 220 hardens, the removable bottom retainer base 230, the removable bottom center retainer 240, the removable center retainer sleeve 250, and the ring R are fixed. Next, a tool such as a screwdriver is inserted into the sleeve ring 254 above the removable center retainer sleeve 250, and the removable center retainer sleeve 250 is removed from the embedding material 270 by rotating the removable center retainer sleeve 250, and the removable bottom retainer base 230 and the removable bottom center retainer 240 are removed at the same time, forming a through hole 272 in the embedding material 270. Next, the screws 260 are inserted into the corresponding first double-sided insertion hole member 212 and second double-sided insertion hole member 222, respectively, and the screws 260 are locked by the nuts 262. At this time, the ring R is retained in the center of the roller 200, wherein the outer peripheral portion RO of the ring R is embedded in the embedding material 270, and the inner edge portion RI is exposed by the through hole 272, as shown in Figure 2 Subsequently, the roller 200 with the locked screws 260 can be placed in a heating furnace for heating.

[0039] Please refer to Figure 8 and Figure 9This is a schematic diagram illustrating, according to an embodiment of the present invention, the roller 200 being mounted on the rolling platform 410. After the roller 200 is heated to the forging temperature, it is placed on the rolling platform 410 of the base 400, ready to perform a rolling operation on the annular object R. While the roller 200 is being heated, the... Figure 4 The roller rolling device 300 is ready. The cylindrical roller 310 in the middle of the roller rolling device 300 is movably inserted into the insertion hole 332 of the bearing liner rotating joint 330, so it can be removed or installed at any time. The other bearings 320, bearing liner rotating joints 330 and bearing mounting tubes 340 are normally fixed, that is, the bearing liner rotating joints 330 on both sides are pre-installed in the bearings 320, and the bearings 320 are also embedded in the bearing mounting tubes 340.

[0040] During installation, such as Figure 8 As shown, the polygonal portion at the right end of the cylindrical rolling roller 310 can be inserted into the insertion hole 332 of the bearing liner rotating joint 330 inside the bearing liner of the bearing 320 within the right bearing mounting tube 340, and then inserted into the fixing tube 536 on the right side of the rolling section 530 of the machine base 500. Next, the cylindrical rolling roller 310 is inserted... Figure 2 The perforation 272 of the embedded material 270 of the roller 200 shown is in the annular material R. For example... Figure 9 As shown, the bearing mounting tube 340, bearing 320, and bearing liner adapter 330, which have already been installed on the left, are then inserted into the fixing tube 536 on the left side of the rolling section 530, and the polygonal portion at the left end of the cylindrical rolling roller 310 is inserted into the insertion hole 332 of the bearing liner adapter 330 of the left bearing 320. Next, the nut 538 is tightened onto the threaded structure 536b of the fixing tube 536, thus completing the installation of the roller 200 and the rolling roller device 300.

[0041] At this point, the rolling operation of the ring-shaped material R can begin. Please refer to... Figure 1 The operator places both hands on the fixed tubes 536 on both sides of the rolling section 530 of the machine tool 500 and applies downward force to press the cylindrical rolling roller 310 down onto the inner edge RI of the annular object R inside the roller 200. The operator then applies force to press the rolling section 530 of the machine tool 500 downward and push the machine tool 500 forward on the track 420 of the base 400. The operator can then apply force to press the rolling section 530 of the machine tool 500 downward and pull the machine tool 500 backward. By repeatedly pressing the rolling section 530 of the machine tool 500 downward and rolling forward and backward several times, the rolling operation is completed. The number of rolling operations depends on the specific conditions of the work being carried out on site. The rolling operation can also be designed to be pressurized and moved using hydraulic or electric methods, eliminating the need for manual labor.

[0042] After the rolling operation is completed, the nuts 538 on the fixed tubes 536 on both sides of the rolling part 530 of the machine 500 are removed, and the bearing installation tube 340, the bearing 320, the bearing lining turning joint 330, and the cylindrical rolling wheel 310 in the middle of the rolling wheel device 300 on either side are removed, and then the bearing installation tube 340, the bearing 320, and the bearing lining turning joint 330 on the other side are also removed. Next, the rolling drum 200 is removed, the screw 260 is removed after the nut 262 is loosened, and then the circular frames 210 and 220 of the rolling drum 200 are separated. Then, the embedding 270 is knocked apart, the rolled ring R is taken out, and the next stage of operation, such as grinding, can be performed on the ring R.

[0043] As can be seen from the above embodiments, the embedding of the rolling drum of the ring rolling device of the present application can tightly cover the peripheral part of the ring, and the perforation in the center of the embedding can expose the inner edge part of the ring. In this way, the cylindrical rolling wheel penetrates the perforation of the embedding to roll the inner edge part of the ring, and in the process of increasing the density of the ring body, the peripheral part of the ring is protected by the embedding, so that the opportunity of damaging the texture and pattern structure on the peripheral part of the ring can be effectively avoided. In addition, the rolling drum is circular, and the perforation is located in the center of the rolling drum, so that the cylindrical rolling wheel can smoothly and uniformly roll the inner edge part of the ring.

[0044] Although the present application has been disclosed as above by way of examples, it is not intended to limit the present application, and any person skilled in the art in this technical field can make various modifications and decorations without departing from the spirit and scope of the present application, and therefore the protection scope of the present application shall be subject to the appended claims.
