Description

Technical Field

[0001] This utility model relates to the field of jade processing technology, and more specifically to a jade processing device for horizontally cutting drill cores. Background Technology

[0002] As a non-renewable resource, how to conserve material and maximize its value during jade carving is the first issue every jade carver must consider. "Pocketing" is an important process in the production of jade vessels. It belongs to the internal carving technique of jade artifacts. When removing the jade from the inside of jade artifacts such as bottles, bowls, and cups, a sleeve is generally used to hollow out the interior.

[0003] According to the "Illustrations of Jade Carving," the traditional hollowing technique involved mounting a steel cylinder on a lathe with an iron shaft and grinding it using the same method as splitting the material. Finally, a jade core was left inside the cavity, which was then gently removed with a small hammer. In modern jade carving, hollowing techniques typically involve using a sleeve to peel away layers, leaving a jade core inside, which is then gently removed with a small hammer. Parts that cannot be removed with a sleeve are ground away bit by bit. This hollowing method works from the inside out, resulting in hollow cylinders from the jade, often only suitable for small items like bracelets or thumb rings. Both methods result in significant waste of jade material, and achieving whole-piece hollowing has always been a challenging technique in jade carving. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a jade processing device for horizontal cutting of cores, which realizes the hollowing out of a whole piece of jade and maximizes the value of the jade material.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A jade processing device for transverse cutting of cores includes a base and a hollow drill cylinder disposed above the base. A turntable is mounted on the base, and the turntable has chucks for fixing the jade to be processed. A servo motor for driving the turntable to rotate is disposed below the base. Two upper through holes for passing diamond wire are opposite each other in the middle of the drill cylinder. A lower through hole for passing diamond wire is disposed below the upper through holes at the bottom of the drill cylinder. A first support plate is disposed between the two upper through holes at the top of the drill cylinder. A tensioning mechanism is disposed on the first support plate for tightening and fixing the two ends of the diamond wire passing through the upper and lower through holes. An external spray pipe for spraying water into the drill cylinder for cooling and lubrication is disposed above the drill cylinder.

[0007] To further optimize the technical solution, the tensioning mechanism includes a second support plate that is vertically mounted on the first support plate by bolts, and wire tensioners for tightening the diamond wires on the corresponding sides are respectively provided at the upper ends of the second support plate.

[0008] The technical solution is further optimized. The wire tensioner includes a U-shaped retainer set in the opposite direction on the second support plate. The wire tensioner is set laterally on the U-shaped retainer by a thread, and the diamond wire is wound around the wire tensioner of the U-shaped retainer.

[0009] To further optimize the technical solution, a rotating screw is provided on the bolt between the first support plate and the second support plate, and a hexagonal nut and washer for fixing the bolt are provided below the rotating screw.

[0010] To further optimize the technical solution, the base has a water outlet hole on its side for the outflow of rinsing and cooling water.

[0011] To further optimize the technical solution, the turntable is mounted on the base via a deep groove ball bearing.

[0012] To further optimize the technical solution, the outer wall of the drill barrel is provided with scale lines for marking the drilling depth of the drill barrel.

[0013] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

It performs horizontal cutting from the bottom of the drill bit, which can extract a complete cylindrical raw material from the belly of a jade carving vessel. This achieves core extraction from the whole piece of jade, maximizing the value of the jade material. Furthermore, this device can be widely used in the production of large vessels that require complete core extraction, enriching the jade carving techniques. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] A jade processing device for horizontally cutting drill cores, combined with Figures 1 to 6 As shown, it includes a base 11 and a drill barrel 9 mounted on the base 11. A turntable 16 is mounted on the base 11, and a chuck 10 is mounted on the turntable 16 to fix the jade to be processed. The turntable 16 is mounted on the base 11 via a deep groove ball bearing 18. A servo motor 19 is mounted below the base 11 to drive the turntable to rotate.

[0024] Two upper through holes 12 are opened opposite each other in the middle of the drill barrel 9. A lower through hole 14 is opened below the upper through holes 12 at the bottom end of the drill barrel 9. The upper through holes 12 and the lower through holes 14 are on the same vertical line and are used to pass through the diamond wire 17. A first support plate 8 is inserted between the two upper through holes 12 at the top of the drill barrel 9. A tensioning mechanism is provided on the first support plate 8 to tighten and fix the two ends of the diamond wire 17 passing through the upper through holes 12 and the lower through holes 14.

[0025] The tensioning mechanism includes a second support plate 4 vertically mounted above the first support plate 8 via bolts 3. Wire tensioners 2 are installed at both ends of the upper part of the second support plate 4 to tighten the diamond wires 17 on the corresponding sides. A rotating screw 5 is installed on the bolt 3 between the first support plate 8 and the second support plate 4. A hexagonal nut 6 and a washer 7 are installed below the rotating screw 5 to fix the bolt 3, thereby fixing the second support plate to the first support plate.

[0026] The wire tensioner 2 includes a U-shaped retainer 20 mounted on the second support plate 4. The U-shaped retainer 20 is installed in reverse. The wire tensioner 2 is threaded laterally mounted on the U-shaped retainer 20. The diamond wire 17 is wound around the wire tensioner 2 inside the U-shaped retainer 20. When the wire tensioner 2 is rotated, the diamond wire is wound around the wire tensioner, thus achieving the tightening of the diamond wire.

[0027] An external jet pipe 1 is provided above the drill barrel 9 to spray water into the drill barrel 9 for cooling and lubrication. A water outlet 15 is provided on the side of the base 11 to drain excess rinsing and cooling wastewater and wastewater containing jade powder.

[0028] The outer wall of the drill barrel 9 is provided with scale lines 13 to mark the depth to which the drill barrel extends into the jade.

[0029] In this invention, during the core extraction operation, a sleeve is first used to drill into the jade to be processed to determine the maximum bore diameter. The jade is then placed on a turntable and secured with jaws. A diamond wire is passed through the upper and lower through holes of the drill barrel. Both ends of the diamond wire are inserted downwards through the holes at the bottom of the drill barrel and exit through the upper through hole, where they are wound around a wire tensioner. The diamond wire at the bottom of the drill barrel is pulled to the edge of the bottom. The drill barrel is then placed into the prepared lower borehole. At this point, the diamond wire is located at the edge of the lower borehole. The wire is then tightened. The wire tensioner keeps the diamond wire taut. The servo motor drives the turntable to rotate, causing the jade to rotate. As the jade rotates, the operator holds the drill barrel. Because the diamond wire is taut, it cuts and polishes the edge of the rotating jade. During the cutting process from the right outside to the inside, the diameter of the jade gradually decreases, and the diamond wire gradually loosens. Therefore, the wire tensioner is gradually tightened during the cutting process to ensure that the diamond wire is taut. When the middle is cut, the core separates from the bottom, cutting a complete piece of jade.
