[0064] In order to make the technical purpose, technical scheme and technical effect of the present invention clearer and to facilitate those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] like Figure 1 As shown, the present invention proposes a production device for multi-layer diamond agglomerates, including a multi-layer material distribution device, a diamond material distribution 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 and used for driving the mold 417 to slide on the slide rail 702; a mold cavity 424 is opened on the mold 417;

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

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

[0068] In the above technical solution, the multi-layer feeding device and the diamond feeding device alternately feed the materials into the mold cavity 424, thereby realizing the multi-layering of the diamond agglomerate. The production equipment of the multi-layer diamond agglomerate of the present invention adopts the cooperation of the multi-layer feeding device and the diamond feeding device, and can continuously produce multi-layer diamond agglomerates with a high degree of mechanization. Furthermore, the mold driving mechanism can adopt a belt drive 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 mounted on the machine platform 701 and a first driving shaft 708 rotatably mounted on the first cylinder 707; a first driving wheel 704 is relatively fixedly sleeved on the first driving shaft 708, and a first driven wheel 705 is rotatably mounted on the machine platform 701; a first belt 706 is transmission-connected between the first driving wheel 704 and the first driven wheel 705;

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

[0072] like Figure 2-Figure 3 As shown, the present invention proposes a multi-layer feeding device, including a plurality of quantitative structures 3 corresponding to completely different or non-completely the same multi-tube metal powders and used to quantify the multi-tube metal powders respectively, a blanking structure 1, a feeding structure 4 used to receive the metal powder discharged from the blanking structure 1 and feed the metal powder into a mold cavity 424, and a hopper driving mechanism connected to the blanking structure 1 and used to drive the blanking structure 1 to move to the bottom of any quantitative structure 3 so that the blanking structure 1 receives the metal powder discharged by the quantitative structure 3 after quantitative weighing and drives the blanking structure 1 to move to the top of the feeding structure 4 so that the blanking structure 1 feeds the feeding structure 4.

[0073] The multi-layer feeding device, through the cooperation of the feeding structure and the hopper driving mechanism, enables the feeding structure to receive different or non-identical multi-tube metal powders in batches, so that the production equipment of the present invention is suitable for adjusting the types of multi-layer diamond agglomerates. In addition, the multi-layer feeding device can also realize the automation of multi-layer feeding of metal powders.

[0074] Furthermore, in this embodiment, the hopper driving mechanism includes a second driving motor 501, a second driving wheel 502, a second driven wheel 503, a second belt 504 and a support frame 507; the support frame 507 is fixedly mounted on the machine platform 701;

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

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

[0077] Here, the second driving shaft 506 rotates to drive the blanking structure 1 to move with the second belt 504, thereby achieving the technical effect that the blanking structure 1 can be driven to move to the bottom of any quantitative structure 3 to receive the metal powder that is quantitatively weighed and discharged by the quantitative structure 3 and is used to drive the blanking structure 1 to move to the top of the distribution structure 4 to discharge the material to the distribution structure 4. 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 505.

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

[0079] Furthermore, in this embodiment, a plurality of quantitative structures 3 are respectively arranged in parallel.

[0080] Specifically, in this embodiment, Figure 4-Figure 9 As shown, the quantitative structure 3 includes a base 301, a first substrate 302 located above the base 301, a lifting mechanism connected to the base 301 and the first substrate 302 respectively and used to drive the first substrate 302 to perform lifting movement 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] The base 301 is provided with a first through hole 325 , and the first substrate 302 is provided with a stepped hole 308 coaxially arranged with the first through hole 325 ;

[0082] The quantitative structure 3 further includes a connecting cylinder 326 respectively inserted into the first through hole 325 and the step hole 308 and clamped on the step 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 and the connecting cylinder 326 are connected;

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

[0084] The above technical scheme is the basic scheme of the quantitative structure 3. The technical principle of the quantitative structure 3 for the quantitative measurement of metal powder is as follows: 1) the gate switch mechanism 2 is used to close the bottom opening of the first through hole 325; 2) the first linear drive mechanism is used to drive the first slider 305 to slide on the linear guide 304 so that the metal powder guide cylinder 303 and the connecting cylinder 326 are docked; 3) the lifting mechanism is used to adjust the distance of the first substrate 302 relative to the base 301, thereby adjusting the height from the top opening of the connecting cylinder 326 to the bottom opening of the first through hole 325; 4) the metal powder guide cylinder 303 is used to 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. In the above 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 scale of the quantitative structure 3 for the quantitative measurement of 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 respectively fixedly mounted on the first substrate 302, and the first mounting member 306 and the second mounting member 307 are arranged opposite to each other; and 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 of indirectly mounting the linear guide member 304 on the first substrate 302 is achieved.

[0086] In this embodiment, the first mounting member 306 and the second mounting member 307 are both plates, which are respectively connected vertically 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 plates, and can also be block-shaped, column-shaped, etc. At the same time, the linear guide 304 is a rod, and its two ends are respectively fixedly penetrated on the first mounting member 306 and the second mounting member 307; the first slider 305 is slidably sleeved on the linear guide 304.

[0087] Preferably, in other embodiments, the linear guide 304 may be a bar with a rectangular cross section and directly mounted on the first substrate 302 .

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

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

[0090] Driven by the first cylinder 313, the metal powder guide cylinder 303 can be connected with the connecting cylinder 326 along with the first slider 305, or can be deviated from the connecting cylinder 326 along with the first slider 305. In another embodiment, the first linear drive mechanism can also be a ball screw mechanism to drive the first slider 305 to slide.

[0091] Preferably, in this embodiment, the third cylinder 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 312 is indirectly fixedly mounted on the first substrate 302 via 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 provided on the base 301, and the lifting mechanism includes a first guide rod 317, which is fixedly inserted into the first fixing hole 323, and the first substrate 302 is slidably mounted on the first guide rod 317; the lifting mechanism also includes a motor 316, and the motor 316 includes a fourth cylinder 318 and a threaded output shaft 319 installed on the fourth cylinder 318; the fourth cylinder 318 is directly or indirectly fixedly installed on the first substrate 302, and a threaded hole (not shown in the figure) is provided on the base 301, and the threaded output shaft 319 is threadedly connected in the threaded hole. Here, the first guide rod 317, the motor 316, the base 301 and the first substrate 302 are equivalent to a ball screw structure, and the first substrate 302 is lifted and lowered relative to the base 301 by the threaded output shaft 319 rotating forward and reverse in the threaded hole of the base 301.

[0093] Furthermore, the lifting mechanism includes a cushion block 320 fixedly mounted on the first substrate 302, and the fourth cylinder 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 mounted on the first guide rod 317 through the second through hole 324. The fourth cylinder 318 is indirectly fixedly mounted on the first substrate 302 through the cushion block 320. In this embodiment, the first substrate 302 is relatively thin, and the fourth cylinder 318 is firmly fixed through the cushion block 320.

[0094] Furthermore, in this embodiment, there are two first guide rods 317, and the two first guide rods 317 are respectively connected to the base 301, the first substrate 302, and the cushion block 320 in the same manner. By using two first guide rods 317, or more first guide rods 317, the lifting movement of the first substrate 302 relative to the base 301 is more stable.

[0095] Further, a first mounting plate 321 is formed protruding from the first slider 305, and the quantitative 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 is more likely to drive the first slider 305. Preferably, the second mounting plate 322 and the first mounting plate 321 are connected by screws.

[0096] Furthermore, in this embodiment, the quantitative structure 3 further includes a second cylinder 315, which includes a fifth cylinder body 310 directly or indirectly fixedly mounted on the first slider 305 and a second piston rod 309 telescopically mounted on the fifth cylinder body 310; the quantitative structure 3 further includes a ramming hammer 314 fixedly mounted on the second piston rod 309. In this embodiment, the first piston rod 311 has two states of extension and retraction. When the first piston rod 311 is in the retracted state, the metal powder guide cylinder 303 is docked with the connecting cylinder 326, so that the edge and the metal powder are discharged into the inside of the connecting cylinder 326 through the metal powder guide cylinder 303; when the first piston rod 311 is in the extended state, the ramming hammer 314 is coaxially arranged with the connecting cylinder 326, and then the ramming hammer 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] Furthermore, the connecting tube 326 includes a tube body 327 and a ring portion 328 formed outwardly at the top of the tube body 327 , and the connecting tube 326 can be clamped on the step hole 308 through the ring portion 328 .

[0098] like Fig.10 As shown, the material discharging structure 1 includes a first hopper 101, and a material discharging port 116 is provided at the bottom of the first hopper 101;

[0099] The blanking structure 1 also includes a first rotating shaft 112 rotatably mounted directly or indirectly on the first hopper 101, a gate 110 sleeved on the first rotating shaft 112 and used to rotate with the first rotating shaft 112 to open or close the discharge port 116, a gear 111 fixedly sleeved on the first rotating shaft 112, a rack 106 meshing with the gear 111, and a rack drive mechanism connected to the rack 106 and used to drive the rack 106 to move.

[0100] The above technical solution is the basic solution. Fig.10 The state in which the discharge port 116 is opened is shown. Fig.10 In the embodiment, 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 discharge port 116. Afterwards, if the rack 106 moves to the right, the rack 106 drives the gear 111 to rotate in the opposite direction, and the first rotating shaft 112 and the gate 110 rotate in the opposite direction, so that the gate 110 reopens the discharge port 116. In the process of the gate 110 opening or closing the discharge port 116, the gate 110 is in a rotating state, so that 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 quantitatively discharged during the discharge. It can be understood that the gate 110 should be kept as clean and dry as possible.

[0101] Further, Figure 11-Figure 12The 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 in the axial direction, and a first male stop 114 is formed on the inner wall of the second fixing hole 113;

In other embodiments, the first rotating shaft 112 can be directly and rotatably inserted into the second shaft cylinder 107.

[0107] Furthermore, in this embodiment, Fig.10 There are two second shaft cylinders 107 , and the two second shaft cylinders 107 are coaxially arranged opposite to each other; 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 drive mechanism is a third cylinder 104, and the third cylinder 104 includes a sixth cylinder body 103 and a third piston rod 102 telescopically mounted on the sixth cylinder body 103;

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

[0127] Furthermore, 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 fixing 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;

[0132] The characteristic 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 can realize the synchronization of opening or closing of the first switch member 203 and the second switch member 220.

[0133] Further, the third connecting rod 206 and the fourth connecting rod 207 are hingedly connected through a third connecting member 213. The third connecting member 213 can be a structure such as an axis, a nail, a column, etc.

In addition, the mold cavity 424 is opened on the mold 417. The cloth structure 4 of the present invention integrates the cloth tube 415 and the pre-pressing mechanism on the mounting platform 408, and then uses a second linear drive mechanism to indirectly drive the mounting platform 408 to move linearly, and uses a lifting drive mechanism to indirectly drive the mounting platform 408 to move up and down, so that multiple steps of the metal powder agglomeration forming process are realized by using one device.

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

[0141] In this embodiment, the first frame 401 is a square frame, and the first guide rail 402 is rod-shaped, and its two ends are respectively installed on two opposite side walls of the first frame 401.

[0142] Further, in this embodiment, the second linear drive mechanism includes a fifth cylinder 420, which includes an eighth cylinder body 418 fixedly mounted on the first frame 401 and a fifth piston rod 419 telescopically mounted on the eighth cylinder body 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 the pre-pressing mechanism and the material distributing cylinder 415 alternately aligning the mold cavity 424 is more efficient. It can be understood that in other embodiments, the second linear drive mechanism can use a ball screw structure instead of a cylinder to linearly drive the first support platform 404.

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 tamping cone 414 to continue to descend, thereby pre-pressing the metal powder in the mold cavity 424. The tamping cone 414 pokes away the sticky blocks caused by the accumulation of metal powder, thereby tamping 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 telescopically mounted on the tenth cylinder body 409; the pre-pressing mechanism also includes a fifth connecting member 412, and the fifth connecting member 412 is respectively fixedly connected to the seventh piston rods 410 of the two seventh cylinders 411; and the pressing member 413 is fixedly connected to the fifth connecting member 412. Here, the seventh cylinder 411 is indirectly connected to the pressing member 413 through the fifth connecting member 412.

[0149] Furthermore, 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 mounted on the top of the tenth cylinder body 409 of the two seventh cylinders 411 respectively; and the vibration motor 422 is fixedly mounted 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, thereby making it flat.

[0150] Furthermore, a discharge port 416 is provided at the bottom of the distribution cylinder 415 , and the metal powder is discharged through the discharge port 416 .

[0151] like Figure 22-27 As shown, Fig. 22 A schematic structural diagram of a diamond distribution device according to a preferred embodiment of the present invention is shown; Fig.23 Shows Fig. 22 A reference diagram of a diamond distribution device in use; Fig.24 Shows Fig. 22 The schematic diagram of the explosion structure of the material transfer structure and the material suction structure of the diamond material distribution device shown; Fig.25 Shows Fig. 22 Another exploded structural schematic diagram of the material transfer structure and material suction structure of the diamond material distribution device shown; Fig.26 Shows Fig. 22 A partial reference diagram of the suction structure of the diamond material dispensing device shown in FIG.

[0152] like Fig. 22 As shown, the diamond material distribution device includes a material holding structure, a material suction structure, a material suction structure driving mechanism and a material moving structure;

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

[0154] The material suction structure is installed on the material transfer structure. When the third linear drive mechanism 618 drives the material transfer structure to slide on the second guide rail 615 to the first position, the material suction structure is connected with the material holding structure below the first position, and then the diamond particles in the material holding structure are sucked by vacuuming.

[0155] The material suction structure is also used to be driven by the material transfer structure to extend into the mold cavity 424 below the second position when the third linear drive mechanism 618 drives the material transfer structure to slide on the second guide rail 615 to the second position, and then the aforementioned diamond particles are arranged in the mold cavity 424 by breaking the vacuum.

[0156] The above technical solution is a basic solution, and the diamond feeding device realizes the automation of the suction structure for sucking and discharging diamond particles by adopting the drive of the third linear drive mechanism, combined with the cooperation of the material holding structure and the material moving structure. It can be understood that the mold cavity 424 is opened on a mold 417.

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

[0160] A second through cavity is formed in the middle of the movable plate 631, and a top cover 637 is detachably mounted on the top of the movable plate 631 to partially or completely cover 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 needle tubes 634 detachably provided on the first connecting plate 633; ​​the plurality of needle tubes 634 are arranged in an array;

[0162] The second connecting plate 636 is provided with a plurality of communicating holes 644 arranged in an array; the communicating holes 644 correspond one to one with the needle tubes 634;

[0167] Here, the needle tube 634 and the pipeline 643 can slide relative to each other by the driving of the eighth cylinder 625 and the ninth cylinder 628. Specifically, when the top cover 637 is lifted relative to the movable plate 631, the needle tube 634 retracts in the pipeline 643 (such as Fig.26 As shown in FIG. 6A , a receiving groove for accommodating diamond particles is formed at the bottom of the pipeline 643. In addition, the ventilation cavity 638 is evacuated to achieve the adsorption of diamond particles. When the top cover 637 is in close contact with the movable plate 631, the needle tube 634 passes through the bottom of the pipeline 643 (as shown in FIG. 6B ). Fig. 27 As shown in FIG. 6 , the diamond particles can be pushed into the metal powder layer. Since the plurality of pipelines 643 are arranged in an array, the diamond particles can be evenly distributed. In addition, during the diamond particle distribution process, the diamond particles are pushed into the metal powder layer through the needle tube 634, which reduces the airflow generated during the diamond particle distribution process and can improve the quality of the finished diamond saw blade.

[0168] Furthermore, in this embodiment, the material transfer structure further includes a fixed plate 621, and the eleventh cylinder body 623 and the twelfth cylinder body 627 are both fixedly mounted on the fixed plate 621;

[0178] The fourth linear drive 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 dropped from the second hopper 601;

[0179] The fourth linear drive 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 as to facilitate docking of the material holding structure with the material suction structure.

When the adsorption block 635 extends into the material tank 613, the material tank 613 forms a closed space, and the diamond particles in the material tank 613 can be adsorbed in the bottom opening of the pipeline 643 by evacuating the ventilation cavity 638.
