Description

TECHNICAL FIELD

[0001] The present application relates to the field of diamond tool bit processing technology, in particular to a diamond tool bit uniform distribution device. BACKGROUND

[0002] The diamond tool bit is the working main body of a diamond saw blade and a diamond water drill bit. The diamond tool bit is composed of diamond particles and a matrix binder. The diamond particles serve as cutting edges, and the matrix binder serves to fix the diamond particles. The matrix binder is composed of metal elemental powder or metal alloy powder.

[0003] During diamond tool bit processing, the diamond particles and the matrix binder need to be layered and pressed multiple times. The uniformity of the layered diamond particles affects the performance of the tool bit. In order to improve the uniformity of the layered diamond particles, a mesh plate is provided in the diamond particle feeding mechanism in the related technology. The mesh plate has regular mesh holes that meet the distribution requirements of the diamond particles. The mesh plate absorbs the diamond particles under the action of negative pressure, so that the uniformity of the layered diamond particles meets the requirements.

[0004] According to different performance requirements of the diamond tool bit, the particle size requirements and the distribution density requirements of the diamond particles are also different. Accordingly, different specifications of mesh plates are also required. In general, when replacing the mesh plate, the mesh plate of the feeding mechanism needs to be disassembled first, and then the mesh plate that meets the requirements is replaced. The replacement operation of the mesh plate needs to be performed manually after the machine is stopped, which is time-consuming and labor-intensive, and affects the processing efficiency of the diamond tool bit. SUMMARY

[0005] In order to improve the replacement efficiency of the mesh plate of the diamond tool bit uniform distribution device, the present application provides a diamond tool bit uniform distribution device.

[0006] The diamond tool bit uniform distribution device provided by the present application adopts the following technical scheme:

[0007] The device for uniformly distributing diamond cutter heads comprises a workbench, a material tank, distributing devices, a negative pressure control device, a rotating device and a replacing device; the workbench is provided with cutter head molds for forming diamond cutter heads; the material tank is used for containing diamond particles; the distributing devices are used for sucking diamond particles from the material tank and laying the diamond particles on the cutter head molds; the distributing devices are provided in a circumferential array around the rotating device and are simultaneously driven by the rotating device to make intermittent circumferential movements around the same center; the distributing devices comprise distributing heads, the distributing heads are detachably provided with screen plates, the distributing heads are provided with positioning mechanisms capable of keeping the screen plates on the distributing heads, the distributing heads are provided with negative pressure channels, and the negative pressure control device applies negative pressure to the screen holes of the screen plates through the negative pressure channels; and the replacing device is used for taking the screen plates off the distributing heads or sending the screen plates to the distributing heads.

[0008] By adopting the above technical scheme, the distributing devices make circumferential movements around a center under the driving of the rotating device, so that the distributing devices make intermittent movements along circumferential tracks at different workstations, one of the workstations through which the distributing devices move is used as a distributing workstation, the distributing devices can lay diamond particles on the inner sides of the cutter head molds at the distributing workstations, different distributing devices can lay diamond particles on the inner sides of the cutter head molds in a required order by making different distributing devices reach the distributing workstations in a certain order, and diamond cutter heads meeting performance requirements can be manufactured. When it is necessary to replace the screen plates of the distributing devices, the rotating device is used to drive the distributing devices to rotate, so that the distributing device whose screen plate needs to be replaced moves away from the workstation for distributing and reaches a workstation where the replacing device can work, and the replacing device replaces the screen plate on the distributing device. In the above process, the replacing of the screen plates of the distributing devices does not need to be stopped and does not need to be manually performed, so that the replacing efficiency of the screen plates is improved.

[0009] Optionally, the distributing device comprises a distributing head, a horizontal moving mechanism and a vertical moving mechanism; the horizontal moving mechanism is used for driving the distributing head to move in a horizontal direction; and the vertical moving mechanism is used for driving the distributing head to move in a vertical direction; the vertical moving mechanism and the horizontal moving mechanism are both linear modules.

[0010] By adopting the technical scheme, when the distributing device is distributing, the vertical moving mechanism drives the distributing head to descend and approach the chute, the screen plate on the distributing head is adsorbed under the action of the negative pressure control device, when the vertical moving mechanism drives the distributing head to ascend and reset, the horizontal moving mechanism drives the distributing head to move above the cutter head mold, then the vertical moving mechanism drives the distributing head to descend, then the negative pressure control device releases the adsorption of the diamond particles, so that the diamond particles fall into the cutter head mold, and the distributing head moves to reset after the diamond particles are laid. The horizontal moving mechanism and the vertical moving mechanism both adopt linear modules, the linear modules have the advantages of high moving distance precision and stable movement, and large vibration is not easy to occur during the movement of the distributing head, so as to reduce the falling of the diamond particles.

[0011] Optionally, the positioning mechanism comprises a first electromagnet, and the first electromagnet adsorbs the screen plate through magnetic attraction.

[0012] By adopting the technical scheme, when the first electromagnet is powered on, the screen plate can be kept on the distributing head through magnetic attraction, and when the first electromagnet is powered off, the screen plate automatically falls, so that the replacing device can remove the screen plate from the distributing head. The first electromagnet realizes the positioning or release of the screen plate through power-on or power-off, so that the positioning mode of the distributing head to the screen plate is simplified.

[0013] Optionally, the replacing device comprises a magnetic seat, a swing arm mechanism and a horizontal reciprocating driving mechanism, the magnetic seat has a built-in second electromagnet, the magnetic seat is used for adsorbing the screen plate, the magnetic seat is installed on the swing arm mechanism, the swing arm mechanism is used for driving the magnetic seat to rotate and swing up and down, and the horizontal reciprocating driving mechanism is used for driving the swing arm mechanism to move reciprocally in the horizontal direction.

[0014] By adopting the technical scheme, when the screen plate of the distributing device is replaced, the swing arm mechanism rotates and swings the magnetic seat upward to below the screen plate of the corresponding distributing device, when the first electromagnet releases the screen plate, the magnetic seat adsorbs the screen plate, then the swing arm mechanism rotates and swings the magnetic seat and the screen plate downward, so that the screen plate faces downward, and when the magnetic seat is released, the screen plate can fall onto the plane for placing the screen plate. On the other hand, the magnetic seat can also move the screen plate placed on the plane to below the distributing head under the driving of the swing arm mechanism, and when the first electromagnet of the distributing head adsorbs the screen plate, the installation of the screen plate can be realized. The horizontal reciprocating driving mechanism can drive the swing arm mechanism to move reciprocally in the horizontal direction, so that the magnetic seat on the swing arm mechanism can place the screen plate at different positions, so as to facilitate the magnetic seat to adsorb different screen plates subsequently.

[0015] Optionally, the material distributing device further includes a material distributing mechanism, which includes an elastic pressure plate and a swing driving member for driving the elastic pressure plate to swing back and forth, and the elastic pressure plate is used to squeeze the diamond particles located on the lower surface of the mesh plate from bottom to top.

[0016] By adopting the above technical solution, after the screen absorbs the diamond particles, the swing driving member drives the elastic pressure plate to rotate from bottom to top to abut against the diamond particles. When the elastic pressure plate contacts the diamond particles, the diamond particles can move slightly, so that the diamond particles can be in the best adsorption state as much as possible, thereby minimizing the possibility of diamond particles falling.

[0017] Optionally, the elastic pressure plate includes a frame and a plurality of long elastic pressure strips, wherein the plurality of elastic pressure strips are arranged in sequence along a straight line, a ventilation gap is left between two adjacent elastic pressure strips, and both ends of the elastic pressure strips are fixedly connected to the frame respectively.

[0018] By adopting this technical solution, when the elastic pressure plate abuts the diamond particles, the diamond particles can maintain a certain gap between the elastic pressure plate and the screen, thereby maintaining a pressure differential between the upper and lower sides of the screen. By maintaining ventilation gaps between adjacent elastic strips, the impact of the elastic pressure plate on the pressure differential between the upper and lower sides of the screen can be further reduced.

[0019] Optionally, a side of the elastic strip used for abutting against diamond particles is defined as an abutting surface, the cross section of the elastic strip is trapezoidal, and the lower base of the trapezoidal cross section of the elastic strip corresponds to the abutting surface.

[0020] By adopting the above technical solution, the cross-section of the elastic strip is set to be trapezoidal, and the lower bottom of the trapezoidal cross-section corresponds to the abutment surface, which can gradually increase the ventilation gap between the two adjacent elastic strips in the direction away from the abutment surface, making it easier for air to pass through the gap between the two adjacent strips, thereby facilitating the maintenance of pressure difference between the upper and lower sides of the mesh plate.

[0021] Optionally, a sweeping device is provided on one side of the workbench, and the sweeping device is used to sweep away residual diamond particles on the workbench.

[0022] By adopting the above technical solution, a small amount of diamond particles will inevitably fall onto the workbench when the feeding device transfers the diamond particles. At the same time, when the diamond particles are placed on the tool head mold, a small amount will fall outside the molding area of ​​the tool head mold. The sweeping device can sweep the diamond particles off the workbench to keep the workbench surface clean.

[0023] Optionally, a residual material receiving device is provided on one side of the workbench, and the residual material receiving device is used to receive the residual diamond particles swept down by the sweeping device. The residual material receiving device includes a frame, and the frame is provided with a plurality of material boxes arranged vertically. The bottom wall of the material box is a screen, and the mesh size of the screen of each material box gradually increases from top to bottom.

[0024] By adopting the above technical solution, the diamonds swept off the workbench by the sweeping device fall into the residual receiving device. When diamond particles of different particle sizes fall into the residual material receiving device, they will be screened by the screen of the material box, so that diamond particles of different particle sizes are retained on the screens of different mesh sizes, thereby realizing automatic sorting of diamond particles.

[0025] Optionally, the screen is tilted and the frame is provided with a vibrator.

[0026] By adopting this technical solution, the vibrator on the frame can vibrate each material box, reducing the number of smaller diamond particles retained on the larger mesh screen. The screen is tilted, allowing the diamond particles to easily move along the screen surface under the vibration of the vibrator, allowing the screen to maximize its ability to screen diamond particles.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The rotating device drives each feeding device to rotate, causing the feeding device that needs to change the screen to leave the feeding station and arrive at the station where the replacement device can function, allowing the replacement device to replace the screen on the feeding device. In this process, the screen of the feeding device can be replaced without stopping the machine or manual work, which helps improve the efficiency of screen replacement.

[0029] 2. After the screen absorbs the diamond particles, the swing drive drives the elastic pressure plate to rotate from bottom to top to abut against the diamond particles. When the elastic pressure plate contacts the diamond particles, the diamond particles can move slightly, so that the diamond particles can be in the best adsorption state as much as possible, thereby minimizing the falling of diamond particles.

DETAILED DESCRIPTION

[0037] The following will be described in detail with reference to the accompanying drawings. Figures 1-5 The present application is further described in detail.

[0038] The present embodiment discloses a diamond cutter head uniform distribution device. Referring to Figure 1 , Figure 2 and Figure 3 , the diamond cutter head uniform distribution device comprises a workbench 1, a material tank 2, a material distribution device 3, a negative pressure control device 4, a rotating device 5 and a replacement device 6; the workbench 1 is provided with a cutter head mold 11 for forming a diamond cutter head, and the material tank 2 is used for containing diamond particles; the material distribution device 3 is provided with four, and is distributed in a circumferential array around the rotating device 5, the rotating device 5 is used for driving multiple material distribution devices 3 to make circumferential motion intermittently around the same center at the same time, and the rotating device 5 is a vertically installed motor; the number of material tanks 2 is not less than four, and the distribution positions of the material tanks 2 are set according to the circumferential motion track of the material distribution device 3; the material distribution device 3 has a detachable screen plate 31, the screen plate 31 has ferromagnetism, and the screen plate 31 of the material distribution device 3 can adsorb diamond particles in the material tank 2 under the action of negative pressure of the negative pressure control device 4; the replacement device 6 is used for replacing the screen plate 31 of the material distribution device 3.

[0039] The four distributing devices 3 make intermittent circular motion around the same center under the action of the rotating device 5, and the screen plate 31 of the distributing device 3 can adsorb diamond particles under the action of negative pressure of the negative pressure control device 4. The screen plates 31 of the four distributing devices 3 are different in specification, specifically, two screen plates 31 can be different in mesh aperture or different in pitch. When the screen plate 31 needs to be replaced, the rotating device 5 is used to drive the screen plate 31 to move to the working position where the replacing device 6 is located, so that the replacing device 6 can replace the screen plate 31 of the distributing device 3.

[0040] With reference to Figure 1 and Figure 3 , the tool bit mold 11 has a forming groove 111, and the workbench 1 is provided with a base material feeding device 7, which includes a feeding seat 71, a translation mechanism 72 and a hopper 73. The hopper 73 is used to hold the base material, and a feeding hose 74 is connected between the hopper 73 and the feeding seat 71. The translation mechanism 72 is used to drive the feeding seat 71 to translate along the table top of the workbench 1. The feeding seat 71 is used to deliver the base material into the forming groove 111 of the tool bit mold 11. The translation mechanism 72 is a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a linear module.

[0041] The workbench 1 is provided with a pressing-down device 8 and a pushing-up device 9. The pressing-down device 8 includes a pressing-down driving mechanism 81 and a pressing-down column 82, and the pushing-up device 9 includes a pushing-up driving mechanism 91 and a pushing-up column 92. The pressing-down driving mechanism 81 and the pushing-up driving mechanism 91 are both hydraulic mechanisms. The pressing-down column 82 and the pushing-up column 92 are both adapted to the forming groove 111. The forming groove 111 is provided with a through hole vertically. The upper end of the pushing-up column 92 is inserted into the forming groove 111 to block the lower port of the forming groove 111.

[0042] During the cold pressing forming of the diamond tool bit, the translation mechanism 72 drives the feeding seat 71 to reciprocate along the table top of the workbench 1. After the feeding seat 71 delivers the base material from the hopper 73 into the forming groove 111, the feeding seat 71 leaves. Then the distributing device 3 lays the diamond particles on the base material and leaves. Subsequently, the pressing-down device 8 goes down, so that the pressing-down column 82 and the pushing-up column 92 jointly extrude the base material and the diamond particles. After the above process is repeated for several times, the diamond tool bit with a multi-layer structure is formed. The pushing-up device 9 pushes the diamond tool bit out of the forming groove 111.

[0043] With reference to Figure 1 and Figure 4The material distributing device 3 comprises a material distributing head 32, a horizontal moving mechanism 33 and a vertical moving mechanism 34. The horizontal moving mechanism 33 is fixedly installed on the output shaft of the rotating device 5. The vertical moving mechanism 34 and the horizontal moving mechanism 33 are both linear modules. The screen plate 31 is installed on the lower surface of the material distributing head 32. The material distributing head 32 is provided with a positioning mechanism 35 capable of keeping the screen plate 31 on the material distributing head 32. The positioning mechanism 35 comprises a first electromagnet 351 and a plurality of positioning members 352. The first electromagnet 351 is capable of attracting the screen plate 31 by magnetic attraction. The plurality of positioning members 352 are arranged around the screen plate 31, so that the position of the screen plate 31 on the lower surface of the material distributing head 32 is positioned. The material distributing head 32 is provided with a negative pressure passage 321. The negative pressure control device 4 is capable of exerting negative pressure on the screen holes of the screen plate 31 through the negative pressure passage 321. The negative pressure control device 4 comprises a vacuum pump and a pipeline for connecting the vacuum pump and the material distributing head 32.

[0044] When the material distributing device 3 is distributing materials, the vertical moving mechanism 34 drives the material distributing head 32 to move up and down, and the horizontal moving mechanism 33 drives the material distributing head 32 to move close to or away from the cutter head die 11 along the horizontal direction. Under the joint action of the vertical moving mechanism 34 and the horizontal moving mechanism 33, the material distributing head 32 is capable of moving the diamond particles to the cutter head die 11 through the screen plate 31.

[0045] The screen plate 31 of the material distributing device 3 is attached to the material distributing head 32 by magnetic attraction. When the replacing device 6 needs to replace the screen plate 31 of the material distributing device 3, the original screen plate 31 can be separated from the material distributing head 32 by simply powering off the first electromagnet 351. Similarly, when the replacing device 6 sends the screen plate 31 to the vicinity of the material distributing head 32, the screen plate 31 can be kept on the material distributing head 32 by simply powering on the first electromagnet 351.

[0046] With reference to Figure 4 The material distributing device 3 further comprises a material arranging mechanism 36. The material arranging mechanism 36 comprises an elastic pressing plate 361 and a swing driving member 362 for driving the elastic pressing plate 361 to swing back and forth. The swing driving member 362 is fixedly installed on the material distributing head 32. In this embodiment, the swing driving member 362 is a servo motor. The elastic pressing plate 361 is used for pressing the diamond particles on the lower surface of the screen plate 31 from below.

[0047] When the material distributing head 32 attracts the diamond particles, the swing driving member 362 drives the elastic pressing plate 361 to slightly press the diamond particles on the lower surface of the screen plate 31 from below. Under the abutting force of the elastic pressing plate 361, the diamond particles can automatically adjust the posture, so that the diamond particles can be in the best state of being attracted as much as possible.

[0048] With reference to Figure 4The elastic pressing plate 361 includes a frame 3611 and a plurality of elastic pressing strips 3612 in the shape of long strips. The frame 3611 is connected with the swing driving member 362, the plurality of elastic pressing strips 3612 are arranged in sequence along a straight line, an air gap 3613 is left between two adjacent elastic pressing strips 3612, and the two ends of the elastic pressing strip 3612 are fixedly connected with the frame 3611. One side of the elastic pressing strip 3612 used for abutting against the diamond particles is defined as an abutting side, the cross section of the elastic pressing strip 3612 is in the shape of a trapezoid, and the lower base of the trapezoid-shaped cross section of the elastic pressing strip 3612 corresponds to the abutting side. The air gap 3613 left between the adjacent elastic pressing strips 3612 can reduce the influence of the elastic pressing plate 361 on the pressure difference between the upper and lower sides of the screen plate 31, so as to guarantee the adsorption of the screen plate 31 to the diamond particles.

[0049] With reference to Figure 2 The replacing device 6 includes a magnetic seat 61, a swing arm mechanism 62 and a horizontal reciprocating driving mechanism 63. The horizontal reciprocating driving mechanism 63 is a linear module. The magnetic seat 61 has a built-in second electromagnet and is used for adsorbing the screen plate 31. The magnetic seat 61 is installed on the swing arm mechanism 62. The swing arm mechanism 62 is a servo motor or a stepping motor and is used for driving the magnetic seat 61 to rotate and swing upward and downward. The horizontal reciprocating driving mechanism 63 is used for driving the swing arm mechanism 62 to move reciprocally along the horizontal direction.

[0050] When the screen plate 31 is replaced, the swing arm mechanism 62 rotates and swings the magnetic seat 61 upward to the position below the screen plate 31 of the corresponding cloth device 3. After the first magnet releases the screen plate 31, the magnetic seat 61 adsorbs the screen plate 31, and then the swing arm mechanism 62 rotates and swings the magnetic seat 61 and the screen plate 31 downward. After the screen plate 31 faces downward, the magnetic seat 61 releases the screen plate 31 for unloading. One side of the replacing device 6 can be provided with a placing platform 30 used for placing the screen plate 31. The swing arm mechanism 62 can move the screen plate 31 on the placing platform 30 to the position below the cloth head 32, so that the first magnet of the cloth head 32 adsorbs the screen plate 31. The horizontal reciprocating driving mechanism 63 can drive the swing arm mechanism 62 to move reciprocally along the horizontal direction, so that the magnetic seat 61 on the swing arm mechanism 62 can place the screen plate 31 at different positions.

[0051] With reference to Figure 1 and Figure 5The one side of the workbench 1 is provided with a material sweeping device 10, the material sweeping device 10 is a moving component driven by a pneumatic cylinder or an electric cylinder, and the material sweeping device 10 is used for sweeping away the diamond particle excess material on the workbench 1. The one side of the workbench 1 is provided with an excess material receiving device 20, the excess material receiving device 20 is used for receiving the diamond particle excess material swept by the material sweeping device 10, and the excess material receiving device 20 comprises a frame 201, the frame 201 is provided with a plurality of material boxes 202 arranged in the vertical direction, the bottom wall of each material box 202 is a screen 2021, the screen 2021 is arranged in an inclined manner, the mesh number of the screen 2021 of each material box 202 gradually increases from top to bottom, and the frame 201 is provided with a vibrator 203.

[0052] When the material sweeping device 10 sweeps the diamond particles to the excess material receiving device, the diamond particles are subjected to the vibration screening of the screen 2021, so that the diamond is retained in the corresponding material box 202.

[0053] The implementation principle of the diamond tool bit uniform distribution equipment in the embodiment of the application is as follows: a plurality of distribution devices 3 are driven by the rotating device 5 to make circular motion around a center, so that each distribution device 3 intermittently circulates in different stations according to a circular track, one of the stations through which the distribution device 3 circulates is a distribution station, the distribution device 3 can lay diamond particles on the inner side of the tool bit mold 11 when the distribution device 3 is at the distribution station, different distribution devices 3 can lay diamond particles on the inner side of the tool bit mold 11 in a required order by making the different distribution devices 3 reach the distribution station in a certain order, so as to manufacture diamond tool bits meeting performance requirements.

[0054] When the mesh plate 31 of one of the distribution devices 3 needs to be replaced because the performance requirements of the diamond tool bit to be produced need to be changed or because the mesh plate 31 is damaged, etc., the rotating device is used to drive each distribution device 3 to rotate, so that the distribution device 3 whose mesh plate 31 needs to be replaced is away from the station for distribution and reaches the station where the replacement device 6 can work, and the replacement device 6 is used to replace the mesh plate 31 on the distribution device 3. In the above process, the replacement of the mesh plate 31 of the distribution device 3 does not need to stop and does not need manual replacement of the mesh plate 31, so as to improve the replacement efficiency of the mesh plate 31.

[0055] On the other hand, the mesh plate 31 can be replaced in a state that the diamond tool bit uniform distribution equipment does not stop, and the mesh plate 31 can be replaced in the process of producing the diamond tool bit, so that the four distribution devices 3 can match more than four specifications of mesh plates 31 in the process of producing the diamond tool bit, thereby producing diamond tool bits with more complex and variable layer structures.

[0056] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: any equivalent changes made on the basis of the structure, shape, principle of the application should be covered within the protection scope of the application.
