[0064] To make the technical objectives, technical solutions, and technical effects of the present invention clearer, so that those skilled in the art can understand and implement the present invention, the following will further elaborate on the present invention in conjunction with the accompanying drawings and specific embodiments.

[0065] As Figure 1 shown, the present invention provides a production device for multi-layer diamond compacts, including a multi-layer cloth feeding device, a diamond cloth feeding device, a pressing and forming device 8, a machine table 701, a slide rail 702 installed on the machine table 701, a mold 417 slidably arranged on the slide rail 702, and a mold driving mechanism connected to the mold 417 for driving the mold 417 to slide on the slide rail 702; a mold cavity 424 is formed on the mold 417.

[0066] The multi-layer cloth feeding device, the diamond cloth feeding device, and the pressing and forming device are respectively installed on the machine table 701 and respectively straddle the slide rail 702; the multi-layer cloth feeding device is used to cloth metal powder into the mold cavity 424 when the mold 417 is driven below the multi-layer cloth feeding device; the diamond cloth feeding device is used to arrange diamond particles in the mold cavity 424 and insert them into the metal powder when the mold 417 is driven below the diamond cloth feeding device.

[0067] The pressing and forming device is used to press the metal powder and diamond particles in the mold cavity 424 into multi-layer diamond compacts when the mold 417 is driven below the pressing and forming device.

[0068] In the above technical solution, the multi-layer cloth feeding device and the diamond cloth feeding device alternately cloth into the mold cavity 424, thereby realizing the multi-layer of diamond compacts. The production device for multi-layer diamond compacts of the present invention adopts the cooperation of the multi-layer cloth feeding device and the diamond cloth feeding device, can continuously produce multi-layer diamond compacts, and has a high degree of mechanization. Further, the mold driving mechanism can adopt a belt driving structure or a direct drive structure.

[0069] Specifically, in this embodiment, the mold driving mechanism includes a first driving motor 703, a first driving wheel 704, a first driven wheel 705, and a first belt 706;

[0070] The first driving motor 703 includes a first cylinder 707 relatively fixedly installed on the machine table 701 and a first driving shaft 708 rotatably installed on the first cylinder 707; the first driving wheel 704 is relatively fixedly sleeved on the first driving shaft 708, and the first driven wheel 705 is rotatably installed on the machine table 701; the first belt 706 is drivingly connected between the first driving wheel 704 and the first driven wheel 705.

[0071] The mold 417 is directly or indirectly installed on the first belt 706.

[0072] AsFigures 2 - 3 As shown in Figures 2 - 3 , the present invention provides a multi-layer fabricating device, which includes a plurality of metering structures 3 corresponding one by one to multi-tube metal powders that are completely different or not completely the same and used for respectively metering the multi-tube metal powders, a blanking structure 1, a fabricating structure 4 for receiving the metal powder blanked from the blanking structure 1 and fabricating the metal powder into a mold cavity 424, and a hopper driving mechanism connected to the blanking structure 1 and used for driving the blanking structure 1 to move directly below any one of the metering structures 3 so that the blanking structure 1 receives the metal powder metered and blanked by the metering structure 3 and for driving the blanking structure 1 to move directly above the fabricating structure 4 so that the blanking structure 1 feeds the fabricating structure 4 with the metal powder.

[0073] The multi-layer fabricating device, through the cooperation of the blanking structure and the hopper driving mechanism, enables the blanking structure to receive different or not completely the same multi-tube metal powders in batches, making the production equipment of the present invention applicable to the adjustment of the types of multi-layer diamond agglomerates. In addition, the multi-layer fabricating device can also realize the automation of multi-layer metal powder fabricating.

[0074] Further, in this embodiment, the hopper driving mechanism includes a second driving motor 501, a second driving pulley 502, a second driven pulley 503, a second belt 504, and a support frame 507; the support frame 507 is fixedly installed on the machine table 701;

[0075] The second driving motor 501 includes a second cylinder body 505 relatively fixedly installed on the support frame 507 and a second driving shaft 506 rotatably installed on the second cylinder body 505; the second driving pulley 502 is relatively fixedly sleeved on the second driving shaft 506, and the second driven pulley 503 is rotatably installed on the support frame 507; the second belt 504 is drivingly connected between the second driving pulley 502 and the second driven pulley 503;

[0076] The blanking structure 1 is relatively fixedly installed on the second belt 504.

[0077] Here, by rotating the second driving shaft 506, the blanking structure 1 is driven to move along with the second belt 504, thereby achieving the technical effect of driving the blanking structure 1 to move directly below any one of the metering structures 3 to receive the metal powder metered and blanked by the metering structure 3 and for driving the blanking structure 1 to move directly above the fabricating structure 4 to feed the fabricating structure 4 with the metal powder. Preferably, in this embodiment, the second driving shaft 506 of the second driving motor 501 can rotate forward and reverse relative to the second cylinder body 505.

[0078] In other embodiments, the hopper driving mechanism can adopt a ball screw structure or other linear reciprocating motion structures.

[0079] Further, in this embodiment, the plurality of metering structures 3 are arranged flush with each other.

[0080] Specifically, in this embodiment, as Figures 4 - 9 shown, the metering structure 3 includes a base 301, a first substrate 302 located above the base 301, a lifting mechanism respectively connected to the base 301 and the first substrate 302 and used to drive the first substrate 302 to move up and down relative to the base 301, a linear guide 304 directly or indirectly mounted on the first substrate 302, a first slider 305 slidably mounted on the linear guide 304, and a metal powder guide cylinder 303 directly or indirectly fixedly mounted on the first slider 305;

[0081] A first through hole 325 is formed in the base 301, and a stepped hole 308 coaxially arranged with the first through hole 325 is formed in the first substrate 302;

[0082] The metering structure 3 further includes a connecting cylinder 326 respectively passing through the first through hole 325 and the stepped hole 308 and clamped on the stepped hole 308, and a first linear driving mechanism connected to the first slider 305 and used to drive the first slider 305 to slide on the linear guide 304 so that the metal powder guide cylinder 303 is docked with the connecting cylinder 326;

[0083] The metering structure 3 further includes a gate switch mechanism 2 mounted on the base 301 and used to open or close the bottom opening of the first through hole 325.

[0084] The above technical solution is the basic solution of the metering structure 3. The technical principle of the metering structure 3 for metering metal powder is as follows: 1) Use the gate switch mechanism 2 to close the bottom opening of the first through hole 325; 2) Use the first linear driving mechanism to drive the first slider 305 to slide on the linear guide 304 so that the metal powder guide cylinder 303 is docked with the connecting cylinder 326; 3) Use the lifting mechanism to adjust the distance between the first substrate 302 and the base 301, so as to adjust the height from the top opening of the connecting cylinder 326 to the bottom opening of the first through hole 325; 4) Fill the space between the top opening of the connecting cylinder 326 and the bottom opening of the first through hole 325 with metal powder through the metal powder guide cylinder 303. In the foregoing technical principle, by adjusting the height from the top opening of the connecting cylinder 326 to the bottom opening of the first through hole 325, the metering scale of the metering structure 3 for metal powder can be adjusted. In this embodiment, the base 301 is relatively fixedly mounted on the support frame 507. In other embodiments, the gate switch mechanism 2 is relatively fixedly mounted on the support frame 507.

[0085] Furthermore, in this embodiment, the quantitative structure 3 includes a first mounting member 306 and a second mounting member 307 which are respectively fixedly mounted on the first substrate 302, and the first mounting member 306 and the second mounting member 307 are arranged oppositely; both ends of the linear guide member 304 are respectively fixedly mounted on the first mounting member 306 and the second mounting member 307. In this way, the technical effect that the linear guide member 304 is indirectly mounted on the first substrate 302 is achieved.

[0086] In this embodiment, both the first mounting member 306 and the second mounting member 307 are plate bodies and are respectively vertically connected to the first substrate 302. It can be understood that the shapes of the first mounting member 306 and the second mounting member 307 are not limited to plate shapes, and can also be block shapes, column shapes, etc. At the same time, the linear guide member 304 is a rod body, and both ends thereof are respectively fixedly passed through the first mounting member 306 and the second mounting member 307; the first slider 305 is slidably sleeved on the linear guide member 304.

[0087] Preferably, in other embodiments, the linear guide member 304 can be a strip body with a rectangular cross-section and is directly mounted on the first substrate 302.

[0088] Furthermore, in this embodiment, the first linear driving mechanism is a first air cylinder 313, and the first air cylinder 313 includes a third cylinder body 312 and a first piston rod 311 which is telescopically mounted on the third cylinder body 312;

[0089] The third cylinder body 312 is directly or indirectly fixedly mounted on the first substrate 302, and the first piston rod 311 is directly or indirectly fixedly connected to the first slider 305.

[0090] Through the driving of the first air cylinder 313, the metal powder guide cylinder 303 can be docked with the connecting cylinder 326 along with the first slider 305, or can deviate from the connecting cylinder 326 along with the first slider 305. In another embodiment, the first linear driving mechanism can also be a ball screw mechanism to drive the first slider 305 to slide.

[0091] Preferably, in this embodiment, the third cylinder body 312 is fixedly mounted on the second mounting member 307, and the first piston rod 311 telescopically passes through the second mounting member 307. In this way, the third cylinder body 312 is indirectly fixedly mounted on the first substrate 302 through the second mounting member 307, thereby reducing the size of the first substrate 302.

[0092] Further, in this embodiment, a first fixing hole 323 is formed on the base 301. The lifting mechanism includes a first guiding rod 317 which is fixedly inserted into the first fixing hole 323. The first substrate 302 is slidably sleeved on the first guiding rod 317. The lifting mechanism further includes a motor 316 which includes a fourth cylinder block 318 and a threaded output shaft 319 mounted on the fourth cylinder block 318. The fourth cylinder block 318 is directly or indirectly fixedly mounted on the first substrate 302. A threaded hole (not shown in the figure) is formed on the base 301, and the threaded output shaft 319 is threadedly connected to the threaded hole. Here, the first guiding rod 317, the motor 316, the base 301 and the first substrate 302 are equivalent to a ball screw structure. By the forward and reverse rotation of the threaded output shaft 319 in the threaded hole of the base 301, the first substrate 302 is lifted and lowered relative to the base 301.

[0093] Further, the lifting mechanism includes a cushion block 320 fixedly mounted on the first substrate 302, and the fourth cylinder block 318 is fixedly mounted on the cushion block 320. A second through hole 324 is formed on the cushion block 320, and the cushion block 320 is slidably sleeved on the first guiding rod 317 through the second through hole 324. Through the cushion block 320, the fourth cylinder block 318 is indirectly fixedly mounted on the first substrate 302. In this embodiment, the first substrate 302 is relatively thin, and the firm fixation of the fourth cylinder block 318 is achieved through the cushion block 320.

[0094] Further, in this embodiment, there are two first guiding rods 317, and the connection manners of the two first guiding rods 317 with the base 301, the first substrate 302 and the cushion block 320 are the same. Through the two first guiding rods 317, or more first guiding rods 317, the lifting movement of the first substrate 302 relative to the base 301 is made more stable.

[0095] Further, a first mounting plate 321 protrudes from the first slider 305. The metering structure 3 further includes a second mounting plate 322 fixedly mounted on the first piston rod 311, and the second mounting plate 322 is fixedly connected to the first mounting plate 321. Through the second mounting plate 322 and the first mounting plate 321, the first cylinder 313 can more easily drive the first slider 305. Preferably, the second mounting plate 322 and the first mounting plate 321 are connected by screws.

[0096] Further, in this embodiment, the metering structure 3 further includes a second cylinder 315. The second cylinder 315 includes a fifth cylinder body 310 fixedly installed directly or indirectly on the first slider 305 and a second piston rod 309 telescopically installed on the fifth cylinder body 310. The metering structure 3 further includes a rammer 314 fixedly installed on the second piston rod 309. In this embodiment, the first piston rod 311 has two states: extending and retracting. When the first piston rod 311 is in the retracted state, the metal powder guiding cylinder 303 is docked with the connecting cylinder 326, so that the metal powder passes through the metal powder guiding cylinder 303 and feeds into the connecting cylinder 326. When the first piston rod 311 is in the extended state, the rammer 314 is coaxially arranged with the connecting cylinder 326, and then the rammer 314 is driven by the second cylinder 315 to extend into the connecting cylinder 326 to flatten the metal powder inside the connecting cylinder 326.

[0097] Further, the connecting cylinder 326 includes a cylinder body 327 and a ring portion 328 formed by turning outwards at the top of the cylinder body 327. The connecting cylinder 326 can be clamped on the stepped hole 308 through the ring portion 328.

[0098] As Figure 10 shown, the blanking structure 1 includes a first hopper 101, and a blanking opening 116 is formed at the bottom of the first hopper 101.

[0099] The blanking structure 1 further includes a first rotating shaft 112 rotatably installed directly or indirectly on the first hopper 101, a gate 110 sleeved on the first rotating shaft 112 and used to open or close the blanking opening 116 as the first rotating shaft 112 rotates, a gear 111 fixedly sleeved on the first rotating shaft 112, a rack 106 meshing with the gear 111, and a rack driving mechanism connected to the rack 106 and used to drive the rack 106 to move.

[0100] The above technical solution is the basic solution. Figure 10 It shows the state where the blanking opening 116 is open. In Figure 10 , when the rack 106 moves to the left, the rack 106 drives the gear 111 to rotate, and the first rotating shaft 112 and the gate 110 rotate accordingly, so that the gate 110 closes the blanking opening 116. After that, if the rack 106 moves to the right, the rack 106 will drive the gear 111 to rotate reversely, and the first rotating shaft 112 and the gate 110 rotate reversely accordingly, so that the gate 110 reopens the blanking opening 116. During the process of the gate 110 opening or closing the blanking opening 116, the gate 110 is in a rotating state. In this way, the metal powder discharged from the first hopper 101 will not remain on the gate 110, thereby reducing the deviation of the metal powder that needs to be metered during blanking. It can be understood that the gate 110 should be kept as clean and dry as possible.

[0101] Further, Figures 11 - 12, the gate 110 includes a gate body 109 and a first shaft cylinder 108 fixedly connected to the gate body 109; the first shaft cylinder 108 has a second fixing hole 113 axially, and a first male stop 114 is formed on the inner wall of the second fixing hole 113;

[0102] The first rotating shaft 112 is provided with a female stop 115. The first rotating shaft 112 passes through the second fixing hole 113, and the female stop 115 and the first male stop 114 are matched with each other.

[0103] Here, through the mutual cooperation of the female stop 115 and the first male stop 114, it is realized that the first rotating shaft 112 and the gate 110 can rotate synchronously.

[0106] Further, in this embodiment, as Figure 10 shown, a second shaft cylinder 107 is provided on the first hopper 101; the first rotating shaft 112 is rotatably passed through the second shaft cylinder 107, so as to achieve the effect of being rotatably and indirectly installed on the first hopper 101. In other embodiments, the first rotating shaft 112 can be directly and rotatably passed through the second shaft cylinder 107.

[0107] Further, in this embodiment, in Figure 10 there are two second shaft cylinders 107, and the two second shaft cylinders 107 are arranged coaxially and oppositely; the first shaft cylinder 108 is located between the two second shaft cylinders 107, so that the first rotating shaft 112 is respectively passed through the two second shaft cylinders 107 and the second fixing hole 113.

[0108] Further, in this embodiment, the rack driving mechanism is a third cylinder 104, and the third cylinder 104 includes a sixth cylinder body 103 and a third piston rod 102 telescopically installed on the sixth cylinder body 103;

It can be understood that in other embodiments, the rack driving mechanism can adopt a ball screw structure or other structures capable of realizing linear reciprocating motion.

[0111] Further, the blanking structure 1 further includes a connection structure fixedly connected to the sixth cylinder block 103 and the first hopper 101 respectively.

[0116] The gate switch mechanism 2 further includes a second rotating shaft 218 rotatably installed on the base 201, a first switch member 203 relatively fixedly sleeved on the second rotating shaft 218 and used to open or close the first gate 202 as the second rotating shaft 218 rotates, a first connecting rod 204 relatively fixedly installed on the second rotating shaft 218, a second connecting rod 205 directly or indirectly rotatably installed on the base 201, a third connecting rod 206 whose two ends are respectively hinged to the first connecting rod 204 and the second connecting rod 205, a fourth connecting rod 207 connected to the middle of the third connecting rod 206, and a connecting rod driving mechanism connected to the fourth connecting rod 207 and used to drive the fourth connecting rod 207 to move.

[0117] Based on the above technical solution, the first connecting rod, the second connecting rod and the third connecting rod form a four-bar mechanism. The connecting rod driving mechanism drives the first connecting rod to rotate through the fourth connecting rod, thereby driving the second rotating shaft 218 and the first switch member to rotate synchronously, realizing the function of opening or closing the first gate 202. In this embodiment, the base 201 is relatively fixedly installed on the support frame 507.

[0118] Further, as Figure 16 shown, the first switch member 203 includes a baffle 217 and a fixed cylinder 216 fixedly connected to the baffle 217; the fixed cylinder 216 is relatively fixedly sleeved on the second rotating shaft 218.Figure 16 As can be seen, the second rotating shaft 218 and the fixed cylinder 216 are relatively fixed through a spigot. It can be understood that the relative fixing manner of the second rotating shaft 218 and the fixed cylinder 216 can also be achieved by methods such as integral molding, welding, and gluing.

[0125] The gate opening and closing mechanism 2 further includes a second switch member 220 relatively fixedly sleeved on the third rotating shaft and used for opening or closing the second gate 219 as the third rotating shaft rotates.

[0126] Here, through the aforementioned four-bar mechanism, the first switch member 203 and the second switch member 220 can be synchronously opened or closed.

[0127] Further, the structure of the second switch member 220 is the same as that of the first switch member 203, and both include a baffle 217 and a fixed cylinder 216 fixedly connected to the baffle 217;

[0128] The fixed cylinder 216 of the first switch member 203 is relatively fixedly sleeved on the second rotating shaft 218;

[0129] The fixed cylinder 216 of the second switch member 220 is relatively fixedly sleeved on the third rotating shaft.

[0130] Further, the first link 204 and the third link 206 are hinged by a second connecting member 215; the second connecting member 215 can be a structure such as a shaft, a nail, or a column.

[0131] The distance between the axial direction of the second connecting member 215 and the axial direction of the second rotating shaft 218 is equal to the distance between the axial direction of the first connecting member 214 and the axial direction of the third rotating shaft.

[0132] By the feature that the distance between the axial direction of the second connecting member 215 and the axial direction of the second rotating shaft 218 is equal to the distance between the axial direction of the first connecting member 214 and the axial direction of the third rotating shaft, the synchronous opening or closing degree of the first switch member 203 and the second switch member 220 can be achieved.

[0133] Further, the third link 206 and the fourth link 207 are hinged by a third connecting member 213. The third connecting member 213 can be a structure such as a shaft, a nail, or a column.

[0134] Further, the link driving mechanism is a fourth cylinder 211. The fourth cylinder 211 includes a seventh cylinder block 210 and a fourth piston rod 209 that is telescopically installed on the seventh cylinder block 210;

The link driving mechanism can also adopt a ball screw structure or other structures that can achieve linear reciprocating motion.

[0136] In this embodiment, the seventh cylinder block 210 is directly or indirectly installed on the base 201. It can be understood that in other embodiments, the seventh cylinder block 210 may also have no contact with the base 201.

[0137] In other embodiments, the gate switch mechanism 2 can also adopt a common cylinder, a ball screw structure or a linear motor to drive the baffle to achieve the technical effect of opening or closing the bottom opening of the first through hole 325.

[0138] Such as Figures 17 - 21As shown, the cloth structure 4 includes a first frame 401, a first guide rail 402 fixedly installed on the first frame 401, a first support platform 404 slidably directly or indirectly installed on the first guide rail 402, an installation platform 408 located below the first support platform 404, a lifting drive mechanism respectively connected to the first support platform 404 and the installation platform 408 and used to drive the installation platform 408 to move up and down relative to the first support platform 404, a cloth cylinder 415 installed on the installation platform 408 and used to introduce metal powder into a mold cavity 424, a pre-pressing mechanism directly or indirectly installed on the installation platform 408 and used to pre-press the metal powder in the mold cavity 424, and a second linear drive mechanism installed on the first frame 401 and used to drive the first support platform 404 to slide on the first guide rail 402.

[0139] Based on the above technical solution, the method of cloth feeding through the cloth structure 4 includes the following steps: 1) Using the second linear drive mechanism to drive the first support platform 404 to drive the installation platform 408 and the cloth cylinder 415 to move, so that the cloth cylinder 415 is aligned with the mold cavity 424; 2) Driving the installation platform 408 to move downward relative to the first support platform 404 through the lifting drive mechanism until the cloth cylinder 415 is docked with the mold cavity 424; then feeding the metal powder into the mold cavity 424 through the cloth cylinder 415; 3) Driving the installation platform 408 to move upward relative to the first support platform 404 through the lifting drive mechanism; 4) Using the second linear drive mechanism to drive the first support platform 404 to drive the installation platform 408 and the pre-pressing mechanism to move, so that the pre-pressing mechanism is aligned with the mold cavity 424; 5) Driving the installation platform 408 to move downward relative to the first support platform 404 through the lifting drive mechanism, so that the pre-pressing mechanism pre-presses the metal powder in the mold cavity 424. In addition, the mold cavity 424 is opened on the mold 417. The cloth structure 4 of the present invention integrates both the cloth cylinder 415 and the pre-pressing mechanism on the installation platform 408, then indirectly drives the installation platform 408 to move linearly by using the second linear drive mechanism, and indirectly drives the installation platform 408 to move up and down by using the lifting drive mechanism, realizing that multiple steps of the forming process of metal powder agglomeration are achieved by one device.

[0140] Furthermore, the cloth structure 4 further includes a metal powder dispersion frame 423 fixedly arranged in the cloth cylinder 415. The metal powder dispersion frame 423 is in a grid structure.

[0141] In this embodiment, the first frame 401 is a square-shaped frame; the first guide rail 402 is rod-shaped, and its two ends are respectively installed on opposite side walls of the first frame 401. In other embodiments, the installation structure of the first guide rail 402 on the first frame 401 can be in a suspended shape.

[0142] Further, in this embodiment, the second linear drive mechanism includes a fifth cylinder 420. The fifth cylinder 420 includes an eighth cylinder block 418 fixedly mounted on the first frame 401 and a fifth piston rod 419 telescopically mounted on the eighth cylinder block 418. The fifth piston rod 419 is directly or indirectly fixedly connected to the first support platform 404. By adopting the fifth cylinder 420, the stroke of alternately aligning the pre-pressing mechanism and the fabric cylinder 415 with the mold cavity 424 is made more efficient. It can be understood that in other embodiments, the second linear drive mechanism can adopt a ball screw structure to replace the cylinder to linearly drive the first support platform 404.

[0143] Further, there are two first guide rails 402. The two first guide rails 402 are arranged in parallel and are respectively fixedly connected to the first frame 401. The fabric structure 4 includes two second sliders 403. The second sliders 403 correspond to the first guide rails 402 one by one. The second sliders 403 are slidably mounted on the corresponding first guide rails 402. The first support platform 404 is respectively fixedly connected to the two second sliders 403.

[0144] The second linear drive mechanism further includes a fourth connecting member 421. The fourth connecting member 421 is respectively fixedly connected to the two second sliders 403. The fifth piston rod 419 is located between the two first guide rails 402, and the fifth piston rod 419 is fixedly connected to the fourth connecting member 421.

[0145] Here, the first support platform 404 realizes the technical effect of being slidably and indirectly mounted on the first guide rail 402 by being respectively fixedly connected to the two second sliders 403. Through the fourth connecting member 421, the synchronous movement of the two second sliders 403 is realized.

[0146] Further, the lifting drive mechanism includes two sixth cylinders 407. Each sixth cylinder 407 includes a ninth cylinder block 405 and a sixth piston rod 406 telescopically mounted on the ninth cylinder block 405.

The ninth cylinder blocks 405 of the two sixth cylinders 407 are also respectively slidably mounted on the corresponding first guide rails 402. The sixth piston rods 406 of the two sixth cylinders 407 are both fixedly connected to the mounting platform 408.

[0147] Further, in this embodiment, the pre-pressing mechanism includes a pressing member 413, a ramming cone 414 formed at the bottom of the pressing member 413, and a seventh cylinder 411 that is directly or indirectly connected to the pressing member 413 and connected to the mounting platform 408 for driving the pressing member 413 to move up and down. Here, after the lifting drive mechanism drives the mounting platform 408 to descend relative to the first support platform 404, the seventh cylinder 411 can be used to drive the pressing member 413 and the ramming cone 414 to continue descending, so as to pre-press the metal powder in the mold cavity 424. The ramming cone 414 pokes and disperses the agglomerated blocks caused by the accumulation of metal powder, thereby ramming the metal powder in the mold cavity 424.

[0148] Further, in this embodiment, there are two seventh cylinders 411; each seventh cylinder 411 includes a tenth cylinder body 409 and a seventh piston rod 410 that is telescopically installed on the tenth cylinder body 409; the pre-pressing mechanism further includes a fifth connecting member 412, and the fifth connecting member 412 is fixedly connected to the seventh piston rods 410 of the two seventh cylinders 411 respectively; the pressing member 413 is fixedly connected to the fifth connecting member 412. Here, through the fifth connecting member 412, the seventh cylinder 411 is indirectly connected to the pressing member 413.

[0149] Further, in this embodiment, the pre-pressing mechanism further includes a sixth connecting member 425 and a vibration motor 422; the sixth connecting member 425 is fixedly installed on the tops of the tenth cylinder bodies 409 of the two seventh cylinders 411 respectively; the vibration motor 422 is fixedly installed on the sixth connecting member 425. Here, the vibration motor 422 indirectly oscillates the metal powder in the mold cavity 424 through the seventh cylinder 411, so as to make it flat.

[0150] Further, a discharge port 416 is formed at the bottom of the cloth feeding cylinder 415, and the metal powder is discharged through the discharge port 416.

[0151] As Figures 22 - 27 shown, Figure 22 Fig. shows a schematic structural diagram of the diamond cloth feeding device according to the preferred embodiment of the present invention; Figure 23 Fig. shows Figure 22 a reference diagram of a use state of the diamond cloth feeding device shown in Figure 24 Fig. shows Figure 22 an exploded structural diagram of the material transfer structure and the material suction structure of the diamond cloth feeding device shown in Figure 25 Fig. shows Figure 22 another exploded structural diagram of the material transfer structure and the material suction structure of the diamond cloth feeding device shown in Figure 26 Fig. shows Figure 22 a reference diagram of a partial use state of the material suction structure of the diamond cloth feeding device shown in Figure 27 Fig. shows Figure 22Another partial usage state reference diagram of the material suction structure of the diamond cloth spreading device shown.

[0152] As Figure 22 shown, the diamond cloth spreading device includes a material holding structure, a material suction structure, a material suction structure driving mechanism, and a material transferring structure;

[0153] The material suction structure driving mechanism includes a second frame 614, a second guide rail 615 fixedly installed on the second frame 614, a second support platform 616 slidably installed on the second guide rail 615, and a third linear driving mechanism 618 installed on the second frame 614 for driving the second support platform 616 to slide on the second guide rail 615; the material transferring structure is installed on the second support platform 616; the second frame 614 is fixedly installed on the machine table 701;

[0154] The material suction structure is installed on the material transferring structure. When the third linear driving mechanism 618 drives the material transferring structure to slide to the first position on the second guide rail 615, the material suction structure is used to dock with the material holding structure below the first position, and then adsorb the diamond particles in the material holding structure by means of vacuum pumping;

[0155] The material suction structure is further used to be driven by the material transferring structure to extend into the mold cavity 424 below the second position when the third linear driving mechanism 618 drives the material transferring structure to slide to the second position on the second guide rail 615, and then arrange the aforementioned diamond particles in the mold cavity 424 by means of breaking the vacuum.

[0156] Based on the above technical solution, the diamond cloth spreading device realizes the automation of the material suction and discharging of the diamond particles by the material suction structure through the drive of the third linear driving mechanism and the cooperation of the material holding structure and the material transferring structure. It can be understood that the mold cavity 424 is opened on a mold 417.

[0157] Furthermore, in this embodiment, a first through cavity (not shown in the figure) is opened in the middle of the second support platform 616; the material transferring structure includes a second substrate 630, an eighth cylinder 625, and a ninth cylinder 628; the second substrate 630 is installed on the top of the second support platform 616 and covers the top opening of the first through cavity; the material suction structure includes a top cover 637 and a movable plate 631;

[0158] The second substrate 630 is respectively provided with a third through hole and a fourth through hole; The eighth cylinder 625 includes an eleventh cylinder body 623 directly or indirectly mounted on the second substrate 630 and an eighth piston rod 624 slidably passing through the third through hole, passing through the second substrate 630 through the third through hole, extending into the first through cavity and fixedly connected to the top cover 637, and telescopically mounted on the eleventh cylinder body 623; A ventilation cavity 638 is provided at the bottom of the top cover 637; A vacuum pumping hole 639 communicating with the ventilation cavity 638 and used for connecting with a vacuum pumping device (not shown in the figure) is provided at the top of the top cover 637;

[0159] The ninth cylinder 628 includes a twelfth cylinder body 627 directly or indirectly mounted on the second substrate 630 and a ninth piston rod 626 slidably passing through the fourth through hole, passing through the second substrate 630 through the fourth through hole, extending into the first through cavity and fixedly connected to the movable plate 631, and telescopically mounted on the twelfth cylinder body 627;

[0160] A second through cavity is provided in the middle of the movable plate 631, and the top cover 637 is detachably mounted on the top of the movable plate 631, covering part or all of the second through cavity;

[0161] The material suction structure further includes a first connecting plate 633, a second connecting plate 636, and a plurality of syringe needles 634 detachably inserted through the first connecting plate 633 respectively; The plurality of syringe needles 634 are arranged in an array;

[0162] A plurality of communication holes 644 arranged in an array are provided on the second connecting plate 636; The communication holes 644 correspond to the syringe needles 634 one by one;

[0163] The second connecting plate 636 is covered on the first connecting plate 633, fixing the plurality of syringe needles 634 therebetween and making the syringe needles 634 communicate with the corresponding communication holes 644;

[0164] The first connecting plate 633 and the second connecting plate 636 are both fixedly connected to the bottom of the top cover 637 by screws or pins, so that the bottom opening of the ventilation cavity 638 is covered by the second connecting plate 636 and communicates with all or part of the plurality of communication holes 644;

[0165] The material suction structure further includes a third substrate 632 fixedly mounted on the bottom of the movable plate 631 and an adsorption block 635 inserted through the third substrate 632;

[0167] Here, through the driving of the eighth cylinder 625 and the ninth cylinder 628, the syringe 634 and the pipeline 643 can slide relative to each other. Specifically, when the top cover 637 is lifted relative to the movable plate 631, the syringe 634 retracts in the pipeline 643 (as Figure 26 shown), resulting in the formation of a receiving groove for accommodating diamond particles at the bottom of the pipeline 643. Coupled with evacuating the ventilation cavity 638, the adsorption of diamond particles can be achieved. When the top cover 637 is in close contact with the movable plate 631, the syringe 634 penetrates through the bottom of the pipeline 643 (as Figure 27 shown), and the diamond particles can be pushed into the metal powder layer. Due to the array distribution of multiple pipelines 643, the diamond particles can be evenly distributed. In addition, during the process of distributing diamond particles, the diamond particles are pushed into the metal powder layer by the syringe 634, reducing the air flow generated during the process of distributing diamond particles and improving the quality of the finished diamond saw blade.

[0168] Further, in this embodiment, the material transfer structure further includes a fixing plate 621, and the eleventh cylinder block 623 and the twelfth cylinder block 627 are both fixedly installed on the fixing plate 621;

[0169] The material transfer structure further includes a plurality of columns 620 respectively connected between the fixing plate 621 and the second substrate 630.

[0170] Through the columns 620 and the fixing plate 621, the eleventh cylinder block 623 and the twelfth cylinder block 627 are respectively indirectly fixed on the second substrate 630.

[0171] Further, the material transfer structure further includes a positioning plate 622 arranged in parallel with the fixing plate 621, and the eleventh cylinder block 623 and the twelfth cylinder block 627 are respectively fixedly connected to the positioning plate 622.

[0173] Here, by adopting the stabilizing plate 629, when the eighth piston rod 624 moves up and down, the suspended top cover 637 can move up and down more stably.

[0174] Further, in this embodiment, the diamond distribution device further includes a driving mechanism for the material receiving structure;

[0175] The driving mechanism for the material receiving structure includes a third frame 602 and a third guide rail 603 fixedly installed on the third frame 602;

[0177] Furthermore, the diamond distributing device further includes a second hopper 601, and the second hopper 601 is fixedly mounted on the third frame 602;

[0178] The fourth linear driving mechanism 608 is used to drive the material holding structure to slide on the third guide rail 603 to a third position below the second hopper 601, so that the material holding structure can receive the diamond particles falling from the second hopper 601;

[0179] The fourth linear driving mechanism 608 is also used to drive the material holding structure to slide on the third guide rail 603 to a fourth position below the first position, so that the material holding structure can be docked with the material suction structure.

[0180] Furthermore, the material holding structure includes a material holding tank body 613, a tenth cylinder 612, and a third slider 605 slidably arranged on the third guide rail 603;

[0181] The tenth cylinder 612 includes a thirteenth cylinder body 611 fixedly mounted on the third slider 605 and a tenth piston rod 610 telescopically mounted on the thirteenth cylinder body 611 and fixedly connected to the material holding tank body 613.

[0182] Here, through the tenth cylinder 612, the lifting of the material holding tank body 613 can be realized, so as to realize the docking of the material holding structure and the material suction structure. When the adsorption block 635 extends into the material holding tank body 613, the material holding tank body 613 forms a closed space. By evacuating the ventilation cavity 638, the diamond particles in the material holding tank body 613 can be adsorbed at the bottom opening of the pipeline 643.

[0183] The material holding structure further includes a second guide rod 642 arranged at the bottom of the material holding tank body 613 and parallel to the tenth piston rod 610;
