Description

Technical Field

[0001] This invention relates to the field of shaping and polishing machines, and more specifically, to a shaping and polishing machine for producing diamond molds. Background Technology

[0002] Diamond molds are molds made from synthetic diamond material, used to manufacture high-precision and highly wear-resistant parts or products. Diamond is one of the hardest materials, possessing excellent wear and corrosion resistance, thus its widespread use in mold making. Diamond molds have a long service life and can maintain good dimensional stability and surface finish for extended periods. They are commonly used in the manufacture of precision plastic parts, hydraulic seals, electronic components, and more.

[0003] Currently, commercially available diamond molds are typically cylindrical with a through-hole in the center, through which steel wire or other materials are drawn. Therefore, in actual use, the cylindrical sizing area of ​​the diamond mold's inner hole must possess a certain degree of precision and a high degree of surface finish. To machine a dimensionally accurate and highly smooth cylindrical shape in the inner hole of an ultra-hard material, a shaping and polishing machine is needed to grind and polish the inner hole of the diamond mold.

[0004] Polishing machines polish diamond molds, typically using diamond wire to grind the inner hole of the mold. The diamond wire moves vertically relative to the inner hole while the mold itself rotates, thus polishing the diamond. However, commercially available polishing machines usually place the diamond mold directly on a mold holder, which then rotates, causing the mold to rotate as well. If the mold holder's sidewalls are too high, the mold is difficult to remove; if they are too low, the mold may detach from the machine during rotation. Furthermore, because the mold is placed directly on the holder, the bottom of the holder and the bottom of the mold experience slight relative displacement during rotation, leading to wear on the bottom of the mold and resulting in low production efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a shaping and polishing machine for producing diamond molds that can fix the diamond mold by clamping and rotating, thereby enabling the rapid removal of the diamond mold.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A shaping and polishing machine for producing diamond molds includes a cabinet. The cabinet includes a top frame, and a cabinet workbench is provided at the bottom of the top frame. A wire coiling unit is provided on the side wall of the top frame, and a liquid injection unit is provided at the top. A lifting unit is provided at the bottom of the liquid injection unit. The lifting unit is installed at the bottom of the wire coiling unit and a clamping and rotating unit is sleeved on it. A wire clamping unit is installed at the bottom of the lifting unit. The lifting unit includes a vertically arranged lifting support frame assembly and a horizontally arranged moving slider assembly. The lifting support frame assembly includes a symmetrically arranged support frame and a secondary support frame. The moving slider assembly includes two symmetrically arranged main mounting plates and secondary mounting plates. The wire clamping unit includes a moving component that fits against the bottom of the lifting unit and a wire clamping component that is slidably connected to the moving component.

[0007] The present invention is further configured such that: the coiling unit includes a coiling frame arranged in a vertical direction, a main coiling spool is rotatably mounted on the side wall of the coiling frame, a secondary coiling spool and an auxiliary coiling spool are arranged around the top of the main coiling spool, and a control plate is arranged at the bottom, with the main coiling spool and the control plate facing each other.

[0008] By adopting the above technical solution, the diamond wire is wound from the outside onto the auxiliary wire reel, which ensures that the diamond wire can smoothly enter the wire winding unit from the outside without tangling. The diamond wire then passes through the top of the auxiliary wire reel and winds onto the main wire reel. The main wire reel can wind the diamond wire required for multiple grinding operations, reducing the frequency of wire feeding and improving production efficiency. A motor is installed on the main wire reel; when wire feeding or changing is needed, the motor drives the main wire reel to rotate, completing the wire feeding or changing. A control plate positioned close to the main wire reel ensures that the diamond wire falls vertically and passes through the axis of the diamond mold's inner hole, thus preventing the diamond wire from shifting during grinding.

[0009] The present invention is further configured such that: the liquid injection unit includes a mounting bracket installed on the side wall of the top frame of the cabinet, a liquid injection gun is slidably connected to the mounting bracket, one end of the liquid injection gun is connected to a liquid injection tube, and the other end of the liquid injection tube is connected to a liquid injection tank disposed inside the top frame of the cabinet.

[0010] The present invention is further configured such that: the support frame is installed on the top of the cabinet workbench, the sub-support frame has the same structure as the support frame and is arranged facing each other, the support frame is provided with a support rod inside, the sub-support frame is provided with a sliding rod inside, and a movable slider assembly is sleeved on the support frame and the sub-support frame.

[0011] The present invention is further configured such that: the movable slider assembly includes a main slider, the main slider is sleeved on a support frame, a secondary slider is sleeved on a secondary support frame, a main mounting plate is connected to the end of the main slider away from the secondary slider, a bottom connecting block is connected to the bottom of the main slider, a secondary mounting plate is installed on the end of the bottom connecting block away from the main slider, a mounting plate connector is connected to the top of the secondary mounting plate, a secondary slider is connected to the top of the mounting plate connector, and the main slider is connected to the end of the mounting plate connector away from the secondary slider.

[0012] The present invention is further configured such that: the clamping and rotating unit includes a pulley assembly, the pulley assembly is sleeved on the lifting unit, and the bottom of the clamping plate assembly is rotatably connected to the main mounting plate and the auxiliary mounting plate; a turntable assembly is connected to one end of the pulley assembly near the main mounting plate; the turntable assembly includes a turntable; a through hole is formed at the center of the top of the turntable; and a set of sliding grooves are formed at the top of the turntable.

[0013] The present invention is further configured such that: a clamping plate assembly is slidably connected to the top of the turntable assembly; the clamping plate assembly includes a clamping rotating frame; a set of connecting members are rotatably connected to the bottom of each corner of the clamping rotating frame; a sliding block is rotatably connected to the bottom of the connecting member; the sliding block is slidably connected inside the sliding groove and has a suitable shape; and a clamping plate is rotatably connected to the top of the connecting member.

[0014] By adopting the above technical solution, multiple sets of clamping plates are set in the clamping plate assembly. These clamping plates cooperate with each other to clamp the diamond mold from multiple surfaces, ensuring that the diamond mold will not loosen or slip during rotation. While ensuring the diamond mold is tightly clamped, a detachable gap is left, allowing for easy replacement of the polished diamond mold. Furthermore, by setting a connector and a sliding block at the bottom of each set of clamping plates, and having the sliding block slide in a sliding groove, the stable rotation of the diamond mold around the vertical axis is ensured, preventing angular deviation and guaranteeing the diamond mold polishing effect.

[0015] The invention is further configured such that: the movable component includes a top plate, and two sets of movable support frames are symmetrically arranged at the bottom of the top plate; a movable rod is inside one set of movable support frames near the clamping component, and a miniature telescopic rod is inside the other set; a matching sliding block is sleeved on the movable rod, and a movable sliding block is sleeved on the miniature telescopic rod.

[0016] The present invention is further configured such that: a movable connector is connected between the mating sliding block and the movable sliding block, the bottom edge of the movable connector is connected to the mating sliding block and the top of the movable sliding block, a wire clamping assembly is connected to the end of the movable sliding block away from the mating sliding block, the wire clamping assembly includes a wire clamping bracket, a rotating block is rotatably connected to the recess of the wire clamping bracket, and two sets of clamping claw modules are symmetrically arranged at the end of the rotating block away from the wire clamping bracket.

[0017] The present invention is further configured such that: the gripper module includes two sets of symmetrically arranged mating rotating parts, the two sets of mating rotating parts are arranged to fit against the side wall of the rotating block, each set of mating rotating parts is connected to a set of gripper arms at the side wall position, a set of gripper heads is installed at the end of the gripper arm away from the rotating block, and a wire clamping motor is arranged vertically at the bottom of the rotating block.

[0018] By adopting the above technical solution, the wire clamping assembly can clamp the diamond wire. Then, the extension and retraction of the miniature telescopic rod can realize the vertical adjustment of the wire clamping assembly. By adjusting the wire clamping assembly vertically, the tension of the diamond wire can be controlled by the movement of the wire clamping assembly after each disassembly. The tension of the diamond wire affects the grinding tension of the diamond wire. Different grinding tensions of the diamond wire will result in different grinding precisions. Therefore, by controlling the movement of the wire clamping assembly, the same grinding precision of the same batch of diamond molds can be guaranteed.

[0019] In summary, this application includes at least one of the following beneficial technical effects of a shaping and polishing machine for producing diamond molds: 1. The diamond wire is wound from the outside onto the auxiliary wire reel, which ensures that the diamond wire can smoothly enter the wire winding unit without tangling. The diamond wire then passes through the top of the auxiliary reel and winds onto the main wire reel. The main wire reel can wind the diamond wire required for multiple grinding passes, reducing the frequency of wire feeding and improving production efficiency. A motor is installed on the main wire reel; when wire feeding or changing is needed, the motor drives the main wire reel to rotate. A control plate positioned against the main wire reel ensures that the diamond wire falls vertically and passes through the central axis of the diamond mold's inner hole, thus preventing the diamond wire from shifting during grinding.

[0020] 2. By incorporating multiple sets of clamping plates in the chuck assembly, these plates work together to clamp the diamond mold from multiple angles, ensuring that the mold does not loosen or slip during rotation. While maintaining a tight grip, the clamping mechanism also allows for easy replacement of the finished mold. Furthermore, by installing connectors and sliding blocks at the bottom of each clamping plate, with the sliding blocks moving within sliding grooves, the stable rotation of the diamond mold around its vertical axis is ensured, preventing angular deviation and guaranteeing optimal diamond polishing results.

[0021] 3. The wire clamping assembly can hold the diamond wire. The extension and retraction of the miniature telescopic rod allows for vertical adjustment of the wire clamping assembly. This vertical adjustment ensures that the tension of the diamond wire can be controlled after each disassembly. The tension of the diamond wire affects the grinding tension, and different grinding tensions result in different grinding precisions. Therefore, by controlling the movement of the wire clamping assembly, the same grinding precision can be ensured for the same batch of diamond molds. Attached Figure Description

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0038] Please see Figure 1-13 The present invention provides the following technical solutions: Example 1, please refer to Figures 1-5 , Figures 10-13A shaping and polishing machine for producing a diamond mold 53 includes a cabinet 1, which provides a working environment for the entire device and ensures the stable operation of the units installed on it. A liquid injection unit 3 is installed at the top of the cabinet 1, which injects polishing fluid into the inner hole 531 of the diamond mold 53. A wire winding unit 2 is installed on the side wall of the cabinet 1, on which diamond wire for polishing can be wound. A vertically positioned lifting unit 4 is installed at the bottom of the wire winding unit 2, which can move the diamond mold 53 vertically, thereby causing the inner hole 531 of the diamond mold 53 to rub against the diamond wire, thus achieving polishing. A horizontally positioned clamping and rotating unit 5 is sleeved on the lifting unit 4, which can rotate relative to the lifting unit 4, thereby causing the inner hole 531 at the center of the diamond mold 53 to be polished 360°. The bottom of the lifting unit 4 is provided with a vertically arranged wire clamping unit 6, which can clamp the diamond wire to ensure that the diamond wire passes through the inner hole 531 of the diamond mold 53, thereby ensuring that the diamond wire polishes the inner hole 531 of the diamond mold 53.

[0039] See Figure 1 The cabinet 1 includes a top frame 11, on which a cable reel unit 2 is mounted. The cable reel unit 2 is horizontally oriented and includes a vertically oriented cable reel frame 21, which is located inside the top frame 11 and is also vertically oriented. A main cable reel 22 is rotatably mounted on the side wall of the cable reel frame 21, providing an installation environment for the main cable reel 22. A motor is mounted on the end of the main cable reel 22 near the cable reel frame 21, enabling the main cable reel 22 to rotate. An auxiliary cable reel 24 is rotatably mounted on the top of the main cable reel 22, and a secondary cable reel 23 is rotatably mounted on one side of the main cable reel 22. A control plate 25 is mounted on the side of the main cable reel 22 away from the secondary cable reel 23, and the control plate 25 is fitted against the side wall of the main cable reel 22.

[0040] Specifically, the diamond wire is wound from the outside onto the auxiliary wire reel 24, which ensures that the diamond wire can smoothly enter the wire reel unit 2 without tangling. The diamond wire then passes through the top of the secondary wire reel 23 and winds onto the main wire reel 22. The main wire reel 22 can wind the diamond wire required for multiple polishing operations, reducing the frequency of wire feeding and improving production efficiency. When wire feeding or changing is needed, the motor drives the main wire reel 22 to rotate, completing the feeding or changing. The wire control plate 25, which is fitted to the main wire reel 22, ensures that the diamond wire falls vertically and passes through the axis of the inner hole 531 of the diamond mold 53, thus preventing the diamond wire from shifting during polishing.

[0041] See Figure 1 , Figure 4A liquid injection unit 3 is installed at the end of the top frame 11 of the cabinet away from the cable tray unit 2. The liquid injection unit 3 includes a mounting bracket 34, on which a movable slider 35 is slidably connected. The movable slider 35 can move horizontally relative to the mounting bracket 34. A liquid injection gun 33 is provided on the side wall of the movable slider 35. The movable slider 35 can drive the liquid injection gun 33 to move, and the liquid injection gun 33 can inject polishing fluid into the inner hole 531 of the diamond mold 53. This avoids the difficulty in controlling the amount of polishing fluid injected due to manual injection, ensuring that the amount of polishing fluid injected each time is consistent, thereby ensuring that the polishing effect is the same each time. The liquid injection gun 33 is connected to a liquid injection tube 32 at its tail end, and the other end of the liquid injection tube 32 is connected to a liquid injection tank 31. A pressure pump is provided inside the liquid injection tank 31. The liquid injection tank 31 can pass the polishing fluid through the liquid injection tube 32 and then inject it into the liquid injection gun 33 to complete the injection of polishing fluid into the diamond mold 53.

[0042] See Figure 5 , Figure 6 A horizontally positioned cabinet workbench 12 is installed at the bottom of the cabinet top frame 11. A lifting support frame assembly 41 is installed on the top of the cabinet workbench 12. The lifting support frame assembly 41 includes a vertically positioned support frame 411. The top of the support frame 411 is fitted against the cabinet top frame 11. The support frame 411 has a C-shaped structure and contains a support rod 413. A secondary support frame 412 is installed on the side of the support frame 411 away from the support rod 413. The secondary support frame 412 has the same structure as the support frame 411 and contains a sliding rod 414. A movable slider assembly 42 is fitted onto the support frame 411 and the secondary support frame 412. The movable slider assembly 42 can slide horizontally on the support frame 411 and the secondary support frame 412.

[0043] See Figure 6 The movable slider assembly 42 includes a main slider 422, which is sleeved on a support rod 413 and can slide vertically on the support rod 413. A secondary slider 424 is sleeved on a sliding rod 414, and a cylinder is mounted on the sliding rod 414, which can drive the secondary slider 424 to slide vertically on the sliding rod 414. A main mounting plate 423 is connected to the end of the main slider 422 away from the secondary slider 424. A bottom connecting block 421 is connected to the bottom of the main slider 422, and a secondary mounting plate 425 is mounted on the end of the bottom connecting block 421 away from the main slider 422. A mounting plate connector 426 is connected to the top of the secondary mounting plate 425, and the secondary slider 424 is connected to the top of the mounting plate connector 426. The main slider 422 is connected to the end of the mounting plate connector 426 away from the secondary slider 424. The bottom connecting block 421 and the mounting plate connector 426 ensure a stable connection between the main mounting plate 423 and the secondary mounting plate 425, preventing them from falling off.

[0044] Specifically, the diamond wire is wound around the coiling unit 2, and after passing through the diamond mold 53, it is tightly clamped by the clamping unit 6. The coiling unit 2 and the clamping unit 6 cooperate to ensure that the diamond wire passes through the axis of the diamond mold 53 and is perpendicular to the diamond mold 53. Then, the diamond mold 53 is placed on the clamping and rotating unit 5, and the liquid injection unit 3 can inject polishing liquid into the inner hole 531 of the diamond mold 53. The diamond mold 53 is tightly clamped by the clamping and rotating unit 5 and rotates at the same time. The lifting unit 4 raises and lowers the diamond mold 53 clamped on the clamping and rotating unit 5, so that the diamond wire passing through the inner hole 531 of the diamond mold 53 can polish the inner hole 531 of the diamond mold 53. The rotation ensures that the diamond wire can polish the inner hole 531 360°, thus ensuring the polishing effect of the diamond mold 53.

[0045] Example 2, please refer to Figures 7-10 This second embodiment improves upon the first embodiment as follows: Although the diamond mold 53 can be rotated and polished by the cooperation of the lifting unit 4 and the clamping rotation unit 5, there is a risk that the diamond mold 53 may fall off during rotation. If a support frame of the same height as the diamond mold 53 is provided on the clamping rotation unit 5 to prevent the diamond mold 53 from falling off, it will be difficult to remove the diamond mold 53 from the support frame. On the other hand, a support frame that is too low not only risks falling off, but also causes the bottom of the diamond mold 53 to rub against the support frame due to swaying, resulting in wear. Therefore, a clamping plate assembly 52 needs to be provided in the clamping rotation unit 5 to ensure that the diamond mold 53 is stably clamped by the clamping rotation unit 5 while ensuring easy removal and avoiding friction between the bottom of the diamond mold 53 and the clamping plate assembly 52.

[0046] See Figure 7 The clamping and rotating unit 5 includes a pulley assembly 54, which is sleeved on the lifting unit 4 and rotatably connected at its bottom to the main mounting plate 423 and the auxiliary mounting plate 425. The pulley assembly 54 provides power to the clamping and rotating unit 5. A turntable assembly 51 is connected to the top of the pulley assembly 54 near the main mounting plate 423. A clamping plate assembly 52 is slidably connected to the top of the turntable assembly 51, providing an installation environment for the clamping plate assembly 52. ​​The turntable assembly 51 includes a turntable 511, with a through hole 513 at the center of its top. The through hole 513 is adapted to the shape of the clamping plate assembly 52 and allows the clamping plate assembly 52 to pass through. A set of sliding grooves 512 are formed on the top of the turntable 511, and the sliding grooves 512 are annular.

[0047] See Figures 8-10The clamping assembly 52 has a drive end at its bottom, which is adapted to the shape of the through hole 513. The drive end of the clamping assembly 52 passes through the through hole 513 and is connected to the pulley assembly 54. The clamping assembly 52 rotates horizontally along the vertical axis via the pulley assembly 54. The clamping assembly 52 is adapted to the shape of the diamond mold 53 and can clamp the diamond mold 53. The clamping assembly 52 includes a clamping rotating frame 521, which can hold the diamond mold 53. The clamping rotating frame 521 is hexagonal in shape and can rotate horizontally at the top of the turntable assembly 51. A set of connectors 523 are rotatably connected to the bottom of each corner of the clamping rotating frame 521. A sliding block 524 is rotatably connected to the bottom of the connector 523, and the connectors 523 provide an installation environment for the sliding block 524. The sliding block 524 is slidably connected inside the sliding groove 512. The shape of the sliding block 524 is adapted to the sliding groove 512. The sliding block 524 can slide along the sliding groove 512, thereby driving the clamping plate assembly 52 to rotate on the turntable assembly 51. Each set of connecting parts 523 is rotatably connected to the top of the clamping plate 522. Multiple sets of clamping plates 522 work together to clamp the diamond mold 53, ensuring that the angle and position of the diamond mold 53 do not shift during rotation and lifting.

[0048] Specifically, by setting multiple sets of clamping plates 522 in the clamping plate assembly 52, the multiple sets of clamping plates 522 cooperate with each other to clamp the diamond mold 53 from multiple faces, ensuring that the diamond mold 53 will not loosen or slide during rotation, and ensuring that the diamond mold 53 is tightly clamped while leaving a detachable gap, which facilitates the replacement of the polished diamond mold 53. Furthermore, by setting a connector 523 and a sliding block 524 at the bottom of each set of clamping plates 522, and the sliding block 524 sliding in the sliding groove 512, the stable rotation of the diamond mold 53 around the vertical axis is ensured, without angular deviation, thus ensuring the polishing effect of the diamond mold 53.

[0049] Example 3, please refer to Figures 11-13 This third example makes the following improvements based on examples two and one. Although the clamping unit 6 can clamp the diamond wire, in actual production, the clamping unit 6 not only needs to clamp the diamond wire but also needs to ensure the tension of the diamond wire. When the diamond wire tension is different, there will be a problem of deviation in the grinding precision and effect of the two sets of diamond molds 53. Therefore, this clamping unit 6 is equipped with a moving component 61 and a clamping component 62. Through the cooperation of the two, the clamping component 62 can be adjusted within a small range, thereby ensuring that the tension is controlled to be the same after each re-clamping of the diamond wire.

[0050] See Figure 11The movable component 61 includes a top plate 611, which is horizontally positioned. Two sets of movable support frames 612 are symmetrically arranged at the bottom of the top plate 611 along the axis of the clamping unit 6. The set of movable support frames 612 closer to the clamping component 62 contains a movable rod 613, while the set of movable support frames 612 further away from the clamping component 62 contains a miniature telescopic rod 617, which can extend and retract vertically. A horizontally positioned sliding block 616 is fitted onto the movable rod 613, and a horizontally positioned sliding block 615 is fitted onto the miniature telescopic rod 617. The sliding block 615 can move as the miniature telescopic rod 617 extends and retracts.

[0051] See Figure 12 A movable connector 614 connects the sliding block 616 and the movable sliding block 615. The movable connector 614 is horizontally oriented and L-shaped. The bottom edge of the movable connector 614 is connected to the top of both the sliding block 616 and the movable sliding block 615, ensuring that the sliding blocks 616 and 615 can move synchronously. A wire clamping assembly 62 is connected to the end of the movable sliding block 615 away from the sliding block 616. The wire clamping assembly 62 can clamp the diamond wire, ensuring that the diamond wire does not fall off during the polishing process. The wire clamping assembly 62 and the wire coiling unit 2 are located on the same axis, and their cooperation ensures that the diamond wire is perpendicular to the diamond mold 53.

[0052] See Figure 13 The wire clamping assembly 62 includes a wire clamping bracket 621, which has a C-shaped structure. A rotating block 622 is rotatably connected to the recess of the wire clamping bracket 621. A wire clamping motor 6234, positioned vertically at the bottom of the rotating block 622, drives the rotating block 622 to rotate, allowing it to rotate 90° along the axis of the wire clamping assembly 62. Two sets of gripper modules 623 are symmetrically arranged along the axis of the wire clamping unit 6 at the end of the rotating block 622 away from the wire clamping bracket 621. The two sets of gripper modules 623 work together to ensure the tight clamping of the diamond wire. The gripper module 623 includes two sets of symmetrically arranged mating rotating parts 6231 along the axis of the rotating block 622. The two sets of mating rotating parts 6231 are fitted against the sidewall of the rotating block 622. When the rotating block 622 rotates, the mating rotating parts 6231 engage with the rotation angle of the rotating block 622, thereby causing the two sets of gripper modules 623 to clamp or release. Each set of mating rotating parts 6231 has a set of gripper arms 6232 connected to its sidewall. Each set of gripper arms 6232 has a set of gripper heads 6233 symmetrically mounted along the axis of the clamping unit 6.

[0053] Specifically, the wire clamping assembly 62 can clamp the diamond wire, and then the extension and retraction of the miniature telescopic rod 617 can realize the vertical adjustment of the wire clamping assembly 62. By adjusting the wire clamping assembly 62 in the vertical direction, the tension of the diamond wire can be controlled by the movement of the wire clamping assembly 62 after each disassembly. The tension of the diamond wire affects the grinding tension of the diamond wire. Different grinding tensions of the diamond wire will result in different grinding precisions. Therefore, by controlling the movement of the wire clamping assembly 62, the same grinding precision of the same batch of diamond molds 53 can be ensured.

[0054] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
