Description

Technical Field

[0001] This application relates to the technical field of permanent magnets, and in particular to a processing technology and processing equipment for permanent magnets. Background Technology

[0002] In addition to the magnetic torque caused by the attraction and repulsion forces of the permanent magnets embedded in the rotor, magnet-embedded motors (IPM motors) can also obtain reluctance torque.

[0003] Current methods for processing permanent magnet blanks involve moving an upper mold downwards to press the permanent magnet raw material powder in the lower mold into a permanent magnet blank. Since the permanent magnet blank is located in a closed space within the lower mold, a tool is needed to push the magnet blank out of the lower mold during demolding, making the demolding process extremely cumbersome. Moreover, the blank processing is also stopped during demolding, which greatly extends the production time of permanent magnets. At the same time, the magnet blank is easily damaged due to friction with the lower mold when it is pushed out, thus reducing the production efficiency and quality of permanent magnets. Summary of the Invention

[0004] In order to improve the production efficiency and quality of permanent magnets, this application provides a processing technology and processing equipment for permanent magnets.

[0005] Firstly, the processing equipment for permanent magnets provided in this application adopts the following technical solution:

[0006] A permanent magnet processing device includes a base and an upper mold slidably disposed on the base. A processing device is disposed on the base, the processing device comprising:

[0007] The machining base is slidably mounted on the machine base;

[0008] Two processing mechanisms are arranged at intervals on the processing base;

[0009] A drive assembly, which is mounted on a base and connected to a machining base and is used to align one of the machining mechanisms with an upper mold.

[0010] A receiving mechanism, which is mounted on the machine base and is used to collect permanent magnet blanks;

[0011] The processing mechanism includes:

[0012] Two lower templates are slidably disposed on the processing base and spliced ​​together to form a processing cavity for loading raw material powder. The projection of the processing cavity and the upper mold along the sliding direction of the upper mold coincides.

[0013] A base plate, which is slidably mounted on the machining seat and serves to block the bottom end of the machining cavity;

[0014] A moving component is mounted on the machine base and connected to two lower templates and a base plate. When the moving component is activated, it moves the base plate and lower templates, causing the permanent magnet blank to fall into the collecting mechanism for collection.

[0015] By adopting the above technical solution, the raw material is added into the processing cavity, the bottom plate prevents the raw material from overflowing, the drive component starts and moves the processing mechanism loaded with raw material to below the upper mold, while the processing mechanism that has been processed moves to the outside of the upper mold. Then the upper mold moves down to press the raw material. At the same time, the moving component starts and moves the bottom plate to open the processing cavity. Then the moving component starts and moves the two lower templates away from the permanent magnet blank at the same time. Therefore, the permanent magnet blank falls down into the material collection mechanism for collection. Then the moving component starts and moves the bottom plate and lower templates back at the same time. Then the raw material is added into the processing cavity again.

[0016] The permanent magnet blank pressing process simultaneously involves material handling and addition, which greatly shortens the processing time. Furthermore, the base plate is moved first, while the two lower templates are used to clamp and position the permanent magnet blank. Then, the two lower templates move away from the permanent magnet blank at the same time, thus unloading the permanent magnet blank. This reduces the probability of wear between the permanent magnet blank and the lower templates due to friction, thereby improving the production efficiency and quality of permanent magnets.

[0017] Optionally, the moving component includes:

[0018] A double-headed cylinder, wherein the double-headed cylinder is mounted on the machining base and is respectively connected to two lower templates;

[0019] A movable cylinder is mounted on a machining base and connected to a base plate.

[0020] By adopting the above technical solution, the dual-head cylinder starts and drives the two lower templates to move closer to or further away from the permanent magnet blank at the same time, while the moving cylinder starts and drives the base plate to move, thereby realizing the movement of the lower template and the base plate.

[0021] Optionally, the processing base and the upper mold are provided with a positioning mechanism for positioning the two lower mold plates, the positioning mechanism including:

[0022] A positioning block, which is slidably disposed on the machining seat in a direction that is close to or far from the lower template;

[0023] A positioning spring is provided on the machining base and connected to the positioning block. When the base plate blocks the machining cavity, the base plate pushes the positioning block to be inserted and installed on the bottom ends of the two lower templates for positioning. When the base plate opens the machining cavity, the positioning block moves back under the action of the positioning spring and disengages from the two lower templates.

[0024] A positioning component is disposed on the upper mold and is used to position the top of the lower mold plate.

[0025] By adopting the above technical solution, when the processing is completed and material needs to be unloaded, the bottom plate moves to open the processing cavity. At the same time, the bottom plate moves away from the positioning block. Under the action of the positioning spring, the positioning block moves back and disengages from the lower template. Then, the lower template can move away from the permanent magnet blank to achieve unloading. When raw materials need to be added, the two lower templates and the bottom plate move back simultaneously. However, the bottom plate moves a greater distance than the two lower templates. Therefore, the lower template moves back to its original position and splices together before the bottom plate. Then, when the bottom plate moves back to its original position, it pushes the positioning block to be inserted and installed on the lower template for positioning, thereby positioning the bottom end of the lower template. The upper mold moves down, causing the positioning component to move closer to the lower template, so that the positioning component connects with the lower template, thereby positioning the top end of the lower template. This achieves positioning of both ends of the two lower templates, thereby further improving the sealing performance after the two lower templates are spliced ​​and improving the production quality of the permanent magnet.

[0026] Optionally, the positioning component includes:

[0027] A positioning frame is disposed on the upper mold;

[0028] Multiple positioning rods are provided on the positioning frame and extend to the side of the upper mold near the lower template, and slide through the two lower templates for positioning.

[0029] By adopting the above technical solution, the upper mold moves downward, causing the positioning frame to move downward. The downward movement of the positioning frame causes multiple positioning rods to slide and pass through the two lower templates. At the same time, the positioning rods move and position themselves along with the upper mold, ensuring that the positioning rods maintain a close distance between themselves and the upper mold's pressing point when positioning the lower templates. This reduces the probability of the two lower templates detaching at the upper mold's pressing point, further improving the sealing between the two lower templates and thus further improving the production quality of the permanent magnets. As the upper mold is processed, it causes the multiple positioning rods to move upward and detach from the lower templates, thus enabling locking and unlocking through the movement of the upper mold. This improves the convenience of positioning the two lower templates, thereby improving the production quality and efficiency of the permanent magnets.

[0030] Optionally, the driving component includes:

[0031] A drive cylinder, which is mounted on the machine base;

[0032] A drive block is mounted on a machining base and connected to the piston rod of a drive cylinder.

[0033] By adopting the above technical solution, the drive cylinder starts to drive the drive block to move, and the drive block moves to drive the processing seat to move, so that one of the two processing mechanisms moves to the bottom of the upper mold and the other moves to the outside of the upper mold. Then the drive cylinder moves back to make the two processing mechanisms exchange positions.

[0034] Optionally, a fixing groove is provided on the lower surface of the upper mold, and a plurality of ventilation holes penetrating the upper mold are provided on the bottom of the fixing groove; a permeable plate is provided on the fixing groove to block the passage of raw materials and allow air to pass through.

[0035] By adopting the above technical solution, when the upper mold extrudes the raw material, the air inside the raw material is discharged through the vent plate and vent holes, thereby reducing the probability of air accumulation in the raw material and reducing the processing quality. When the upper mold moves back, the outside air can enter the lower part of the upper mold through the vent holes and vent plate in sequence, thereby reducing the probability of air damaging the surface of the permanent magnet blank during the extrusion and retraction of the upper mold, and improving the production quality of the permanent magnet.

[0036] Optionally, the receiving mechanism includes:

[0037] Conveyor belt, which is mounted on a machine base;

[0038] A receiving plate is mounted on the machine base at an angle. The receiving plate is used to receive the permanent magnet blank and guide it onto the conveyor belt for transport.

[0039] A buffer assembly is disposed on the receiving plate and is used to buffer the permanent magnet blank.

[0040] By adopting the above technical solution, the permanent magnet blank in the processing cavity falls downward onto the buffer assembly for cushioning. Then, the permanent magnet blank squeezes the buffer assembly and moves to the receiving plate. Next, the permanent magnet blank slides onto the conveyor belt under the action of gravity. The conveyor belt drives the permanent magnet blank to move, so the workers can detect and collect the permanent magnet blank on the conveyor belt. This realizes the feeding, detection and collection of permanent magnet blanks. At the same time, the buffer assembly is used to cushion the permanent magnet blank, thereby improving the production quality of permanent magnets.

[0041] Optionally, the buffer component includes:

[0042] A buffer plate is slidably disposed on a receiving plate and parallel to the side wall of the bottom plate near the processing cavity, and is used to receive the permanent magnet blank.

[0043] A buffer spring is disposed on the receiving plate and connected to the buffer plate.

[0044] By adopting the above technical solution, the permanent magnet blank falls downward onto the buffer plate, the buffer plate squeezes the buffer spring downward, and then the permanent magnet blank presses against the receiving plate. Under the action of the receiving plate, the permanent magnet blank tilts and slides downward onto the conveyor belt, thereby achieving buffering of the permanent magnet blank.

[0045] Optionally, the machine base is provided with a feeding assembly for adding raw materials into the processing cavity, the feeding assembly comprising:

[0046] A receiving box, which is mounted on the machine base and contains raw materials and is located above the lower template;

[0047] The discharge pipe is installed on the receiving box and extends between the two lower mold plates located outside the upper mold, and is equipped with a discharge valve.

[0048] By adopting the above technical solution, the discharge valve is opened, and the raw materials enter the processing chamber through the discharge pipe, thereby realizing the addition of raw materials.

[0049] Secondly, the processing technology for a permanent magnet provided in this application adopts the following technical solution:

[0050] A manufacturing process for a permanent magnet includes the following steps:

[0051] A. Add raw materials: Add the raw materials into the processing unit;

[0052] B. Processing: The upper mold is activated to extrude the raw material located in the processing mechanism.

[0053] In summary, this application includes at least one of the following beneficial technical effects:

[0054] By pressing the permanent magnet blank while simultaneously picking up and adding raw materials, the processing time for permanent magnets is greatly shortened. Moreover, the base plate is moved first, and the two lower templates are used to clamp and position the permanent magnet blank. Then, the two lower templates move away from the permanent magnet blank at the same time, thereby realizing the unloading of the permanent magnet blank. This reduces the probability of wear between the permanent magnet blank and the lower templates due to friction, thereby improving the production efficiency and quality of permanent magnets.

[0060] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0061] This application discloses a processing equipment for permanent magnets.

[0062] Reference Figure 1 The permanent magnet processing equipment includes a base 1 and a mounting plate 18 fixedly installed on the upper surface of the base 1. The two ends of the mounting plate 18 extend horizontally to both sides of the base 1. A fixed seat 11 is fixedly installed on the upper surface of the mounting plate 18 and directly above the base 1. Sliding seats 12 are vertically slidably installed on the side walls opposite to the fixed seat 11. A vertical processing rod 13 is fixedly installed on the lower surface of the sliding seat 12. A horizontal upper mold 14 is fixedly installed at the bottom end of the processing rod 13. A hydraulic cylinder 15 is fixedly installed on the top of the fixed seat 11. The piston rod of the hydraulic cylinder 15 is vertically downward and fixedly connected to the upper surface of the sliding seat 12. When the hydraulic cylinder 15 is activated, it drives the sliding seat 12 and the upper mold 14 to move vertically. A processing device 2 is provided on the base 1. The processing device 2 is used to cooperate with the upper mold 14 to produce permanent magnet blanks.

[0063] Reference Figure 1 and Figure 2The processing device 2 includes a processing base 21, two processing mechanisms 3, a drive assembly 4, and a receiving mechanism 6. The processing base 21 is horizontally slidably mounted on the upper surface of the mounting plate 18, and is located below the sliding base 12 and extends to the outside of the sliding base 12 and the machine base 1. The two processing mechanisms 3 are spaced apart on the processing base 21. The drive assembly 4 is mounted on the mounting plate 18 and connected to the processing base 21, such that one processing mechanism 3 is located directly below the upper mold 14 and performs processing corresponding to the upper mold 14, while the other processing mechanism 3 is located outside the sliding base 12 and the machine base 1 for unloading and loading raw materials. The drive assembly 4 includes a drive cylinder 41 and a drive block 42. The drive cylinder 41 is fixedly mounted on the upper surface of the mounting plate 18, and the drive block 42 is fixedly mounted on the side wall of the processing seat 21. The piston rod of the drive cylinder 41 is fixedly connected to the drive block 42. When the drive cylinder 41 is started, it drives the drive block 42 and the processing seat 21 to move horizontally. A fixing groove is provided on the lower surface of the upper mold 14. A vent hole is provided on the bottom of the fixing groove, which passes through the upper surface of the upper mold 14. A vent plate is fixedly mounted on the fixing groove. The vent plate and the lower surface of the upper mold 14 are flush. The vent plate blocks the material from passing through but allows air to pass through.

[0064] Reference Figure 1 and Figure 2 The following explanation will take the processing mechanism 3 located directly below the upper mold 14 as an example. The processing mechanism 3 includes two lower templates 31, a base plate 32, and a moving component 33. The two lower templates 31 are folded and their ends are spliced ​​together to form a processing cavity 22. The cross-section of the processing cavity 22 is square and coincides with the projection of the upper mold 14 in the vertical direction. The two lower templates 31 are horizontally slidably installed on the processing seat 21, and the two lower templates 31 are close to or far away from each other. When the lower templates 31 move, they simultaneously move away from or close to the two adjacent side walls of the processing cavity 22.

[0065] Reference Figure 2 and Figure 3 The processing cavity 22 is used to add raw materials for processing permanent magnet blanks. The upper surface of the processing seat 21 is provided with a processing hole 23 for the permanent magnet blank to pass through, and the vertical projection of the processing cavity 22 is located in the processing hole 23. The upper surface of the processing seat 21 is provided with a processing groove 24, and the processing groove 24 is connected to one of the side walls of the processing seat 21. The base plate 32 is horizontally slidably installed on the processing groove 24, and the upper surfaces of the base plate 32 and the processing seat 21 are flush. At the same time, the base plate 32 can move to completely block the processing cavity 22 and the processing hole 23, and the movement of the base plate 32 can open the processing cavity 22 and the processing hole 23.

[0066] Reference Figure 2 and Figure 3The moving component 33 is mounted on the processing base 21 and connected to the two lower templates 31 and the base plate 32. The two lower templates 31 move a small distance, only needing to disengage from the permanent magnet blank, while the base plate 32 moves a longer distance, requiring the processing cavity 22 to be fully opened or closed. Therefore, the time spent moving the base plate 32 is greater than the time spent moving the lower templates 31. The moving component 33 includes a double-headed cylinder 34 and a moving cylinder 35. The double-headed cylinder 34 is fixedly mounted on the upper surface of the processing base 21, and the two piston rods of the double-headed cylinder 34 are fixedly connected to the side walls of the two lower templates 31 respectively, so as to realize that the two lower templates 31 move closer or further away from each other. The moving cylinder 35 is fixedly mounted on the side wall of the processing base 21, and the piston rod of the moving cylinder 35 is fixedly connected to the base plate 32.

[0067] Reference Figure 2 and Figure 3 The raw material is added into the processing cavity 22, while the base plate 32 blocks the raw material. Then, the upper mold 14 moves down and extends into the processing cavity 22. The upper mold 14 continues to move down to extrude the raw material. After processing, the upper mold 14 moves up above the lower mold plate 31. Then, the drive cylinder 41 starts and drives the processing seat 21 to move, so that the processing mechanism 3, which has completed processing, moves to the outside of the upper mold 14, while the processing mechanism 3, which has completed feeding and unloading, moves to the bottom of the upper mold 14. The upper mold 14 continues to move down for processing. The mounting plate 18 has mounting holes 19 on both ends outside the upper mold 14. The mounting holes 19 are for pressing the processed permanent magnet blank. Simultaneously, the moving cylinder 35 is activated, driving the base plate 32 to move and open the processing cavity 22 and processing hole 23. At this time, the two lower templates 31 continue to clamp and position the permanent magnet blank. After the base plate 32 is moved, the double-headed cylinder 34 is activated, driving the two lower templates 31 to move away from the processing cavity 22 and the permanent magnet blank. The permanent magnet blank falls downward through the processing hole 23 and the mounting hole 19 to complete the unloading. Then, the double-headed cylinder 34 and the moving cylinder 35 are activated simultaneously, thereby driving the two lower templates 31 to quickly move back to their original positions. The base plate 32 moves back to its original position and blocks the processing cavity 22 and processing hole 23, thus completing the processing of the permanent magnet blank.

[0068] Reference Figure 2 and Figure 3The processing base 21 and the upper mold 14 are provided with positioning mechanisms 5 for positioning the two lower mold plates 31. The positioning mechanism 5 includes a positioning block 51, a positioning spring 52, and a positioning assembly 53. The processing groove 24 has mounting grooves 25 on both sides of the opposite side wall and at the joint of the two lower mold plates 31. Push blocks 37 are fixedly installed on the side wall of the base plate 32 near the two mounting grooves 25 and are slidably mounted on the processing groove 24. The two push blocks 37 are correspondingly set with the two mounting grooves 25. A sliding groove 26 is provided on the side wall for the push block 37 to slide, and the mounting groove 25 is connected to the sliding groove 26; the positioning block 51 is provided at the two mounting grooves 25, and the positioning block 51 includes a moving part 511 and a positioning part 512. The moving part 511 is vertically installed on the mounting groove 25 and extends into the sliding groove 26; two positioning parts 512 are provided and fixedly installed on the upper surface of the moving part 511, and the two positioning parts 512 are respectively corresponding to the two lower templates 31 and slide vertically through the mounting groove 25.

[0069] Reference Figure 2 and Figure 3 One end of the positioning spring 52 is fixedly installed on the bottom of the mounting groove 25, and the other end is fixedly installed on the lower surface of the moving part 511. In the natural state, the two positioning parts 512 retract into the machining seat 21 under the action of the positioning spring 52 and are located below the two lower templates 31. During the process of the bottom plate 32 moving to block the machining cavity 22 and machining hole 23, the push block 37 moves to push the moving part 511 and the two positioning parts 512 upward, so that the two positioning parts 512 are respectively inserted and installed at the splice of the two lower templates 31 for positioning. The bottom end of the lower template 31 is provided with a positioning groove 36 that is inserted and matched with the positioning part 512. The moving part 511 is provided with an inclined guide surface 513 on one end near the push block 37. The guide surface 513 facilitates the push block 37 to move back and push the two positioning parts 512 upward.

[0070] Reference Figure 2 and Figure 3The positioning component 53 is mounted on the upper mold 14 and is used to position the top of the lower mold plate 31. The positioning component 53 includes a positioning frame 54 and multiple positioning rods 55. The positioning groove 36 of the lower mold plate 31 passes through the top of the lower mold plate 31. The positioning frame 54 is fixedly mounted on the side wall of the sliding seat 12. The multiple positioning rods 55 are fixedly mounted on the lower surface of the positioning frame 54, and there are four positioning rods 55, which correspond one-to-one with the two positioning grooves 36 of the two lower mold plates 31. At the same time, the positioning rods 55 extend vertically downward to the upper mold 14. 4. Below; the sliding seat 12 moves down, causing the upper mold 14 and multiple positioning rods 55 to move down simultaneously. The multiple positioning rods 55 are inserted into multiple positioning slots 36 to position the two lower templates 31, while the positioning block 51 is inserted into the bottom of the lower template 31 for positioning. Then the upper mold 14 moves into the processing cavity 22, and the multiple positioning rods 55 and the upper mold 14 move down simultaneously. The upper mold 14 is used to extrude the raw material. After processing, the upper mold 14 and the positioning rods 55 move up to above the lower template 31.

[0071] Reference Figure 2 and Figure 3 The moving cylinder 35 starts, driving the base plate 32 to move and open the processing cavity 22 and processing hole 23. The base plate 32 drives the push block 37 away from the positioning part 512. The positioning part 512 moves back under the action of the positioning spring 52 and disengages from the lower template 31. Then, the double-headed cylinder 34 starts, driving the two lower templates 31 to move away from each other, thereby realizing the unloading of the permanent magnet blank. Then, the double-headed cylinder 34 and the moving cylinder 35 start at the same time. The lower template 31 moves a shorter distance, so that the two lower templates 31 move back to their original positions first. Then, the base plate 32 moves back, driving the push block 37 to push the two positioning parts 512 to be inserted and installed on the two lower templates 31 for positioning.

[0072] Reference Figure 1 and Figure 4 The processing device 2 also includes two receiving mechanisms 6, which are located below the two ends of the mounting plate 18 and on opposite side walls of the machine base 1. The receiving mechanisms 6 are used to collect permanent magnet blanks and are correspondingly arranged with the processing mechanism 3 located outside the upper mold 14. The receiving mechanism 6 includes a conveyor belt 61, a receiving plate 62 and a buffer assembly 7. Mounting frames 17 are fixedly installed on opposite side walls of the machine base 1 and outside the processing seat 21. Two conveying rollers 63 are horizontally rotatably mounted on the mounting frames 17 and are spaced apart along a perpendicular axis to the conveying rollers 63. A conveying motor connected to one of the conveying rollers 63 is fixedly installed on the side wall of the mounting frame 17, and the conveyor belt 61 is sleeved on the two conveying rollers 63.

[0073] Reference Figure 1 and Figure 4The receiving plate 62 is fixedly installed on the side wall of the machine base 1 and located on one side of the conveyor belt 61. At the same time, the receiving plate 62 extends downward at an angle to the conveyor belt 61. The height of the end of the receiving plate 62 near the conveyor belt 61 is lower than the height of the end away from the conveyor belt 61. The receiving plate 62 is used to receive the permanent magnet blank after the processing mechanism 3 unloads it. A receiving groove 64 is opened on the upper surface of the receiving plate 62 and located directly below the processing mechanism 3. At the same time, the vertical projection of the receiving groove 64 is located in the processing cavity 22. The buffer assembly 7 is set on the receiving plate 62 and is used to buffer the permanent magnet blank.

[0074] Reference Figure 1 and Figure 4 The buffer assembly 7 includes a buffer plate 71 and a buffer spring 72. The buffer plate 71 is vertically slidably installed on the bottom of the receiving trough 64 via two buffer rods 73. Two buffer springs 72 are provided and respectively sleeved on the two buffer rods 73. One end of the buffer spring 72 presses against the bottom of the receiving trough 64 and the other end presses against the lower surface of the buffer plate 71. At the same time, the buffer plate 71 is in a horizontal state and is located above the receiving trough 64 in its natural state. The buffer plate 71 is used to catch the permanent magnet blank after it is fed and buffer it. Then the permanent magnet blank comes into contact with the receiving plate 62. The inclined receiving plate 62 causes the permanent magnet blank to tilt and slide down. At the same time, the buffer spring 72 generates a restoring force after the permanent magnet blank slides down and will continue to push the permanent magnet blank to move down. Then the permanent magnet blank falls onto the conveyor belt 61, and the conveyor belt 61 drives the permanent magnet blank to move. Therefore, the staff can detect and collect the permanent magnet blank.

[0075] Reference Figure 1 and Figure 4 Support frames 16 are fixedly installed on both ends of the mounting plate 18 on the outer side of the machine base 1. The top of the support frame 16 extends above the two lower templates 31. Each of the two support frames 16 is provided with a feeding assembly 8 for adding raw materials. The feeding assembly 8 includes a receiving box 81 and a discharge pipe 82. The receiving box 81 is fixedly installed on the top of the support frame 16 and contains raw materials. The discharge pipe 82 is fixedly installed on the side wall of the receiving box 81 near the support frame 16 and extends between the two lower templates 31 and above the lower templates 31. A discharge valve 83 is fixedly installed on the discharge pipe 82. When the discharge valve 83 is opened, the raw materials in the receiving box 81 are added to the processing chamber 22 through the raw materials in the discharge pipe 82.

[0076] The working principle of this application embodiment is as follows:

[0077] The upper mold 14 moves down to extrude the raw material in the processing cavity 22, while the positioning part 512 and the positioning rod 55 position the two lower templates 31. At the same time, the processing mechanism 3 located outside the upper mold 14 unloads and adds raw material. After processing, the upper mold 14 and the positioning rod 55 move above the lower templates 31, and then the drive cylinder 41 starts to drive the two processing mechanisms 3 to move. The processing mechanism 3 that has completed processing moves to the outside of the upper mold 14, while the processing mechanism 3 that has loaded the raw material moves to the bottom of the upper mold 14. Then the processing continues to be repeated.

[0078] After processing, the moving cylinder 35 starts, driving the base plate 32 to move and open the processing hole 23. At the same time, the positioning part 512 is unlocked by moving away from the two lower templates 31 under the action of the positioning spring 52. Then, the double-headed cylinder 34 starts, driving the two lower templates 31 away. As a result, the permanent magnet blank falls down onto the buffer plate 71. Then, the double-headed cylinder 34 and the moving cylinder start simultaneously, so the lower templates 31 quickly move back to their original positions. The base plate 32 moves and pushes the positioning part 512 to be inserted and installed on the two lower templates 31 for positioning. Then, raw materials are added to complete the feeding and adding of raw materials. At the same time, the permanent magnet blank squeezes the buffer plate 71 and comes into contact with the receiving plate 62. Then, the permanent magnet blank moves onto the conveyor belt 61. The conveyor belt 61 moves, driving the permanent magnet blank to move. Therefore, the workers can perform permanent magnet blank inspection and collection, thereby improving the production efficiency and quality of permanent magnets.
