Description

Technical Field

[0001] This invention relates to the field of cutting device technology, specifically a PCD blade cutting device. Background Technology

[0002] PCD (Polycrystalline Dioxide) material is a polycrystalline material formed by agglomerating numerous diamond single-crystal powders under high temperature and pressure using metal binders such as cobalt. Although its hardness is slightly lower than that of single-crystal diamond, it is an aggregate of randomly oriented diamond grains, making it isotropic. When used as a cutting tool, it can be ground in any orientation without requiring the selection of the optimal cleavage plane as the rake face, unlike natural diamond. During cutting, the cutting edge is not very sensitive to accidental damage, has strong wear resistance, and can maintain a sharp cutting edge for a long time. High cutting speeds and large depths of cut can be used during machining, and its service life is generally longer than that of cemented carbide tools. Furthermore, due to the electrical conductivity of the metal binder in PCD, it is easy to cut into various shapes.

[0003] In the existing technology, PCD blade cutting devices are not convenient for switching PCD blades and can only perform a single type of cutting. However, the workpiece to be processed may have a complex cutting process or require composite processing, which requires the use of multiple different models of PCD cutting devices. This not only leads to a significant increase in production costs but also reduces production efficiency.

[0004] Therefore, in order to solve the above-mentioned technical problems in the prior art, a PCD blade cutting device is proposed. Summary of the Invention

Furthermore, by switching PCD blades and using a production line, it can significantly improve production efficiency and reduce production costs.

Since the workpieces to be processed may have complex cutting processes or require composite processing, multiple different models of PCD cutting devices are needed, which not only leads to a significant increase in production costs but also reduces production efficiency.

Moreover, the PCD blade switching by indexing and the assembly line production can greatly improve production efficiency and reduce production costs.

[0017] 2. The PCD blade cutting device uses two sets of intermittent rotating components in the drive mechanism to operate alternately. When the servo motor is running in the forward direction, the conveying mechanism is running and the switching mechanism is not running.

Thus, only one servo motor is needed as a power source to drive the switching mechanism and the conveying mechanism to operate alternately, which reduces the cost of the device and saves energy consumption.

[0018] 3. The PCD blade cutting device uses several U-shaped clips to engage with several rectangular slots and several sliders to slide along two slide rails. This provides support and limits the movement of the two workpieces, ensuring that they can only move in a straight line without deviation. At the same time, the device provides greater support and stability during conveying and cutting. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1-12 A PCD blade cutting device includes a first housing 100, on which two workpieces 200, a first PCD blade 300, a second PCD blade 310, a third PCD blade 320, a conveying mechanism 400, and a rotation mechanism 500 are disposed.

[0034] The conveying mechanism 400 includes two conveying rollers 410, a conveyor belt 420, and a first rotating assembly 430. The two ends of the two conveying rollers 410 are rotatably connected to the inner walls of the two sides of the first housing 100, respectively. The two conveyor belts 420 are drivenly connected to the circumferential surfaces of the two conveying rollers 410. The two workpieces 200 are connected to the upper ends of the two conveyor belts 420. The first rotating assembly 430 is connected to one of the conveying rollers 410 to realize its rotation, thereby conveying the two workpieces 200 through the two conveyor belts 420.

[0035] The indexing mechanism 500 includes a rotating disk 510 and a second rotating assembly 520. The rotating disk 510 is disposed on the upper side of two workpieces 200. The first PCD blade 300, the second PCD blade 310 and the third PCD blade 320 are respectively fixedly installed on several side ends of the rotating disk 510. The second rotating assembly 520 is connected to the rotating disk 510 to realize its rotation, thereby changing the PCD blade, and cooperates with the conveying mechanism 400 to perform cutting operations on the two workpieces 200.

[0036] In this embodiment: the first housing 100 serves as a base, providing fixed support for other structures of the device. Both the front and rear ends of the first housing 100 are open. Two conveyor rollers 410 rotate between the left and right inner walls of the first housing 100. The two conveyor rollers 410 are distributed one in front of the other. A conveyor belt 420 is connected to the left side of the circumferential surface of the two conveyor rollers 410, and a conveyor belt 420 is also connected to the right side of the circumferential surface of the two conveyor rollers 410.

[0037] Two workpieces 200 are connected to the upper ends of the two conveyor belts 420. The two workpieces 200 are distributed one in front of the other and are located in the lower part of the center side of the first housing 100. A rotating disk 510 is provided in the upper part of the center side of the first housing 100. The rotating disk 510 is composed of a frustum with an open top and three rectangular blocks fixed on the lower side. The three rectangular blocks are arranged in a circle and distributed at equal intervals. The lower ends of the three rectangular blocks are respectively fixed with a first PCD blade 300, a second PCD blade 310 and a third PCD blade 320.

[0038] The three blades have different models and cutting effects. Initially, the first PCD blade 300 is in a vertically downward position. A drive mechanism 600 drives the first rotating assembly 430 and the second rotating assembly 520 to operate. The second rotating assembly 520 drives the rotating disk 510 to rotate. This allows switching between the first PCD blade 300, the second PCD blade 310, and the third PCD blade 320, so that one of them rotates to a vertically downward position. The first rotating assembly 430 drives the rear conveyor roller 410 to rotate, which in turn drives the two conveyor belts 420 and the front conveyor roller 410 to rotate as well. Thus, the two conveyor belts 420 transport the two workpieces 200 forward.

[0039] When two workpieces 200 come into contact with one of the first PCD blade 300, the second PCD blade 310, or the third PCD blade 320, the two workpieces 200 will be cut sequentially. For those skilled in the art, the aforementioned first PCD blade 300, second PCD blade 310, and third PCD blade 320 are all prior art and will not be described in detail.

[0040] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 6-10 The first rotating assembly 430 includes a second housing 431, two second rotating rods 432, a half gear 433, and a first straight gear 434.

[0041] The second housing 431 is fixedly connected to the lower inner wall of the first housing 100. One end of each of the two second rotating rods 432 is rotatably connected to one side inner wall of the first housing 100. The other end of each of the two second rotating rods 432 moves through one side inner wall of the second housing 431 and extends inward. The half gear 433 and the first straight gear 434 are respectively fixedly connected to one of the second rotating rods 432 and one of the conveying rollers 410, and the half gear 433 and the first straight gear 434 mesh intermittently.

[0042] The second rotating assembly 520 includes a third housing 521, a fixed column 522, a first bevel gear 523, a second bevel gear 524, a first rotating rod 525, a third rotating rod 526, a chain 527, and two second spur gears 528.

[0043] The third housing 521 is fixedly connected to the upper inner wall of the first housing 100. The fixed column 522 is fixedly connected to the lower end of the third housing 521. The rotating disk 510 is rotatably connected to the circumferential surface of the fixed column 522. The first rotating rod 525 is fixedly connected to the upper end of the rotating disk 510 and is connected to the circumferential inner wall of the third housing 521. One end of the third rotating rod 526 is rotatably connected to one side inner wall of the first housing 100, and the other end of the third rotating rod 526 moves through one side inner wall of the third housing 521 and extends inward. The first bevel gear 523 and the second bevel gear 524 are fixedly connected to the circumferential surfaces of the third rotating rod 526 and the first rotating rod 525, respectively, and the first bevel gear 523 meshes with the second bevel gear 524. Two second spur gears 528 are fixedly connected to the circumferential surfaces of the third rotating rod 526 and the other second rotating rod 432, respectively. The chain 527 is driven and meshed with the circumferential surfaces of the two second spur gears 528.

[0044] In this embodiment: the workpiece 200 to be processed is set to be a rectangular structure. A second housing 431 is fixed in the middle of the lower inner wall of the first housing 100. The second housing 431 is located in the middle of the two conveyor belts 420. The second housing 431 is U-shaped and has openings at the top and both the front and rear ends.

[0045] The right inner wall of the first housing 100 has two second rotating rods 432 that rotate. The two second rotating rods 432 are horizontally distributed one in front of the other. The left ends of the two second rotating rods 432 can move through the right end and the right inner wall of the second housing 431 and extend to the left. The right side of the circumferential surface of the second rotating rod 432 located on the rear side is fixed with a half gear 433. The right side of the circumferential surface of the conveyor roller 410 located on the rear side is fixed with a first straight gear 434. The first straight gear 434 and the half gear 433 mesh intermittently.

[0046] Rotating the second rotating rod 432 located at the rear can drive the half gear 433 to rotate, which in turn drives the first straight gear 434 to rotate, which in turn drives the conveyor roller 410 located at the rear to rotate to convey the two workpieces 200. When the half gear 433 rotates to disengage from the first straight gear 434, the conveyor roller 410 located at the rear will stop rotating, and the two workpieces 200 will stop being conveyed. This process repeats, which allows the two workpieces 200 to be conveyed forward at a fixed frequency, thus preventing the two workpieces 200 from being conveyed too fast and making cutting difficult.

[0047] A third shell 521 is fixed to the middle of the upper inner wall of the first shell 100. The third shell 521 is composed of a hollow trapezoidal block and a cylinder. The inclined surface of the trapezoidal block faces the lower rear side, and there is an opening on the inclined surface that communicates with the interior. The cylinder is fixed at the opening, and the interior of the cylinder is also hollow.

[0048] A fixed post 522 is fixed at the lower end of the cylinder. The rotating disk 510 rotates along the circumferential surface of the fixed post 522. A first rotating rod 525 is fixed at the middle of the upper end of the rotating disk 510. The first rotating rod 525 extends upward into the cavity of the third housing 521 without contacting the third housing 521. A third rotating rod 526 rotates on the right inner wall of the first housing 100. The left end of the third rotating rod 526 moves through the right end and the right inner wall of the third housing 521 and extends to the left.

[0049] A first bevel gear 523 is fixed to the circumferential surface of the third rotating rod 526, and a second bevel gear 524 is fixed to the portion of the circumferential surface of the first rotating rod 525 located inside the third housing 521. The second bevel gear 524 is obliquely meshed with the lower front part of the first bevel gear 523. The first bevel gear 523 and the second bevel gear 524 serve to change the direction of rotation. The rotation of the third rotating rod 526 can drive the first bevel gear 523 to rotate, which in turn drives the second bevel gear 524 and the first rotating rod 525 to rotate, which in turn drives the rotating disk 510 to rotate, thereby realizing the interchange of the first PCD blade 300, the second PCD blade 310 and the third PCD blade 320.

[0050] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 11-12 A drive mechanism 600 is provided on the first housing 100. The drive mechanism 600 is connected to both the first rotating component 430 and the second rotating component 520 to realize their operation.

[0051] The drive mechanism 600 includes a servo motor 610, a third spur gear 620, two fourth spur gears 630, a fourth rotating rod 640, and two sets of intermittent rotation components 650.

[0052] The servo motor 610 is fixedly connected to the inner wall of the other side of the second housing 431. The two fourth rotating rods 640 are rotatably connected to the inner wall of the other side of the second housing 431. The two fourth spur gears 630 are fixedly connected to the circumferential surfaces of the two fourth rotating rods 640 respectively. The third spur gear 620 is fixedly connected to the circumferential surface of the output shaft of the servo motor 610, and the third spur gear 620 meshes with the two fourth spur gears 630. The two fourth rotating rods 640 are connected to the two second rotating rods 432 respectively through two sets of intermittent rotating components 650, and the two sets of intermittent rotating components 650 are symmetrical about the midpoint of the third spur gear 620.

[0053] Each set of intermittent rotating components 650 includes a first annular plate 651, several pawls 652, several springs 653, a connecting block 654, an inner ratchet 655, and a second annular plate 656.

[0054] The first annular plate 651 is fixedly connected to the circumferential surface of one of the fourth rotating rods 640. The connecting block 654 is fixedly connected to one side of the first annular plate 651. Several pawls 652 are rotatably connected to one side of the first annular plate 651. One end of several springs 653 is fixedly connected to several side ends of the connecting block 654, and the other end of several springs 653 is fixedly connected to one side of several pawls 652. The second annular plate 656 is fixedly connected to the circumferential surface of one of the second rotating rods 432. The inner ratchet 655 is fixedly connected to one side of the second annular plate 656, and the inner ratchet 655 is intermittently engaged with several pawls 652.

[0055] In this embodiment: a servo motor 610 is fixed in the middle of the left inner wall of the second housing 431, and two fourth rotating rods 640 are also rotatable on the left inner wall of the second housing 431. The two fourth rotating rods 640 are symmetrically distributed front and back based on the midpoint of the output shaft of the servo motor 610.

[0056] A third spur gear 620 is fixed on the circumferential surface of the output shaft of the servo motor 610, and a fourth spur gear 630 is fixed on the circumferential surface of the two fourth rotating rods 640. The two fourth spur gears 630 mesh with the front and rear sides of the third spur gear 620 respectively. The two sets of intermittent rotating components 650 are connected to the two fourth rotating rods 640 and the two second rotating rods 432 respectively to realize transmission.

[0057] The two sets of intermittent rotation components 650 are also symmetrical about the midpoint of the output shaft of the servo motor 610, and the two sets of intermittent rotation components 650 operate alternately. When the servo motor 610 is running in the forward direction, it will drive the third spur gear 620 to rotate, which in turn will drive the two fourth spur gears 630 to rotate in the same direction. At this time, the intermittent rotation component 650 located on the front side does not operate, the second rotating rod 432 located on the front side does not rotate, and therefore will not drive the rotating disk 510 to rotate for transposition.

[0058] When the intermittent rotating component 650 located at the rear is in operation, the second rotating rod 432 located at the rear will rotate, thereby driving the two conveyor belts 420 to rotate and transport the two workpieces 200. Similarly, when the servo motor 610 rotates in the reverse direction, the switching mechanism will operate and the conveying mechanism 400 will not operate.

[0059] Each of the two fourth rotating rods 640 has a first annular plate 651 fixed to its right side of its circumferential surface. Three pawls 652 rotate at the right edge of each of the two first annular plates 651, and a connecting block 654 is fixed to the middle of the right end of each of the two first annular plates 651. The two connecting blocks 654 and the six pawls 652 are connected by six springs 653. Each of the two second rotating rods 432 has a second annular plate 656 fixed to its left side of its circumferential surface. An inner ratchet 655 is fixed to the left end of each of the two second annular plates 656. The two inner ratchet wheels 655 intermittently mesh with the six pawls 652, with the ratchet teeth of the two inner ratchet wheels 655 facing opposite directions. The ratchet teeth of the three pawls 652 located on the front side and the three pawls 652 located on the rear side also face opposite directions.

[0060] When the two fourth levers 640 rotate in the forward direction, the rotation direction of the three pawls 652 on the front side is in the same direction as the ratchet teeth of the inner ratchet 655 on the front side, and the two will not mesh. The three pawls 652 on the rear side will continuously rotate back and forth in small amplitudes under the compression and rebound action of the three springs 653 on the rear side. Therefore, the inner ratchet 655 and the second annular plate 656 on the front side will not rotate, while the rotation direction of the three pawls 652 on the rear side is opposite to the direction of the ratchet teeth of the inner ratchet 655 on the rear side, and the two will mesh, thereby driving the inner ratchet 655 and the second annular plate 656 on the rear side to rotate.

[0061] Similarly, when the two fourth levers 640 rotate in opposite directions, the inner ratchet 655 and the second annular plate 656 located on the front side will rotate, while the inner ratchet 655 and the second annular plate 656 located on the rear side will not rotate.

[0062] Example 4 is an improvement upon Example 3. For details, please refer to [link / reference]. Figures 1-9 Both conveyor belts 420 have several rectangular slots 440 on their circumferential surfaces. The lower inner wall of the first housing 100 is fixedly connected to two slide rails 230. Both sides of the two workpieces 200 are movably engaged with U-shaped clips 210. Several U-shaped clips 210 are movably engaged in several rectangular slots 440.
