Description

Technical Field

[0001] The invention relates to the technical field of magnet cutting, and in particular to a NdFeB magnet cutting device. Background Art

[0002] NdFeB magnets are widely used in modern industry due to their high remanence, high coercivity and high energy density, especially in the fields of electronics, automobiles, medical equipment, etc.

[0003] The traditional method of cutting NdFeB magnets usually involves manual operation. The specific steps are as follows: First, workers place multiple NdFeB magnets neatly on a marble slab; then, use glue to fix the magnets to the surface of the marble slab to ensure that the magnets do not move or tilt during the cutting process; after the glue is completely dry, the marble slab and the magnets are placed on a multi-wire cutting machine, and the position and speed of the cutting wires are precisely controlled to achieve efficient cutting of the NdFeB magnets.

[0004] Although the above method meets the cutting requirements of NdFeB magnets to a certain extent, it also exposes obvious shortcomings. On the one hand, the process of manual glue application and waiting for the glue to dry takes a long time, which will affect production efficiency and thus increase manufacturing costs. On the other hand, the glue may not be able to fully penetrate into all parts of the contact surface between the magnet and the marble slab. In addition, the contact area between the cut magnet piece and the marble slab is small, which makes the cut magnet piece easy to shift or even fall over. Especially when the cutting line exits the cutting seam, it is very likely to be clamped by the adjacent magnet piece, causing the cutting line to break. This will not only affect the cutting quality, but may also cause damage to the cutting equipment. Summary of the invention

[0005] In view of this, the present invention provides a NdFeB magnet cutting device, which can overcome the shortcomings of the existing cutting machine when cutting the NdFeB magnet, which requires manual glue to fix the NdFeB magnet on the marble slab, the operation is troublesome, and the cut magnet pieces will clamp the cutting line due to tipping, thereby causing the cutting line to break.

The lifting plate 13 is connected between the tops of the two slide bars 12 on the left, and the lifting plate 13 is connected between the tops of the two slide bars 12 on the right. It is also connected to a lifting plate 13, and the number of the lifting plates 13 is two.

The rotating component is used to drive the installation frame 4 to rotate; the rotating component includes a servo motor 15 and a connecting plate 16.

The output shafts of the two servo motors 15 are connected to the connecting plates 16, and the two connecting plates 16 are respectively connected to the left and right sides of the installation frame 4.

[0028] like Figure 4 and Figure 5As shown, the alternating clamping mechanism includes a fixed plate 17, a vertical plate 1701, a marble base plate 18, a sleeve 19, a connecting rod 20, a clamping plate I 21, a clamping plate II 22, an electric push rod III 23 and a flip assembly. A fixed plate 17 is provided on the front side above the bottom plate 1. The fixed plate 17 is located directly above the mounting frame 4. The marble base plate 18 is connected to the middle of the bottom of the fixed plate 17. The front and rear sides of the bottom of the fixed plate 17 are connected to vertical plates 1701. The upper and lower parts of the two vertical plates 1701 are connected with five sleeves 19 at intervals. A connecting rod 20 is slidably connected in each sleeve 19. A clamping plate I 21 is connected between the ends of the five connecting rods 20 located on the upper side, and a clamping plate II 22 is connected between the ends of the five connecting rods 20 located on the lower side. The number of clamping plates II 22 and clamping plates I 21 is two (such as Figure 5 As shown), the height of splint II 22 is greater than the height of splint I 21, and the sum of the height of splint II 22 and the height of splint I 21 is less than the height of the magnet itself, the upper and lower parts of the two vertical plates 1701 are spaced apart and connected with electric push rods III 23, and the telescopic rods of the electric push rods III 23 are respectively connected with splint I 21 and splint II 22, and the flip assembly is used to drive the fixed plate 17 to flip; the flip assembly includes support columns 24, a drive motor 25 and a connecting block 26, the support columns 24 are symmetrically connected to the front side of the top of the bottom plate 1, the upper parts of the two support columns 24 are connected with drive motors 25, the output shafts of the two drive motors 25 are connected with connecting blocks 26, and the bottoms of the two connecting blocks 26 are fixedly connected to the top of the fixed plate 17.

[0029] First, the controller 101 controls the driving motor 25 to drive the connecting block 26 to rotate 180 degrees. The connecting block 26 can drive the fixed plate 17 and the marble substrate 18 to rotate 180 degrees, so that the marble substrate 18 faces upward, and then the magnet is neatly placed on the top of the marble substrate 18 manually. Then, the controller 101 controls the electric push rod III 23 to drive the clamping plates Ⅰ 21 on the front and rear sides to move to the side close to each other, so that the clamping plate Ⅰ 21 can clamp the magnet on the top of the marble substrate 18. Then, the controller 101 controls the driving motor 25 to drive the connecting block 26 to rotate 180 degrees. The connecting block 26 can drive the fixed plate 17 and the marble substrate 18 to rotate 180 degrees, so that the marble substrate 18 faces downward, and the fixed plate 17 can drive the magnet to rotate 180 degrees through the clamping plate Ⅰ 21, so that the magnet is located directly above the mounting frame 4; then, the controller 101 controls the hydraulic cylinder 2, the multi-wire cutting machine body 3 and the electric push rod II 14 to start working. The hydraulic cylinder 2 can drive the multi-wire cutting machine body 3 to move upward. The electric push rod Ⅱ 14 can drive the lifting plate 13 to rise. The lifting speed of the multi-wire cutting machine body 3 and the lifting plate 13 is consistent. The lifting plate 13 can drive the servo motor 15, the connecting plate 16 and the mounting frame 4 to rise. When the cutting line of the multi-wire cutting machine body 3 contacts the magnet, the magnet can be cut. When the top of the mounting frame 4 contacts the bottom of the magnet, the controller 101 will control the electric push rod Ⅱ 14 to stop working, so that the lifting plate 13, the servo motor 15, the connecting plate 16 and the mounting frame 4 stop rising, and the multi-wire cutting machine body 3 will continue to rise to cut the magnet. At the same time, the controller 101 will control the electric push rod Ⅰ 8 to start working. The electric push rod Ⅰ 8 drives the mounting plate 6 to move upward along the guide rod 5. The mounting plate 6 can drive the sliding plate 7 to move upward, so that the sliding plate 7 extends out of the top of the mounting frame 4 and is inserted into the cutting slit of the magnet. The rising speed of the sliding plate 7 is consistent with the rising speed of the multi-wire cutting machine body 3. When the height of the cutting line of the multi-wire cutting machine body 3 is higher than the top of the clamping plate Ⅱ 22 (such as Figure 8 As shown, at this time, the magnet is in the shape of magnet II002), the controller 101 will control the electric push rod I8 to stop working, so that the mounting plate 6 and the sliding plate 7 stop moving upward, and at the same time, the controller 101 will control the electric push rod III23 to drive the front and rear clamping plates II22 to move closer to each other, so that the clamping plates II22 clamp the magnet. Since the sliding plate 7 is located in the cutting gap of the magnet, the sliding plate 7 can maintain the position of the magnet sheet under the clamping action of the clamping plates II22. Then the controller 101 will control the electric push rod III23 to drive the front and rear clamping plates I21 to move away from each other, so that the clamping plates I21 release the magnet until the multi-wire cutting machine body 3 completely slices the magnet (such as Figure 8As shown, at this time, the magnet is in the shape of magnet III003), the controller 101 will control the multi-wire cutting machine body 3 to stop working; then the controller 101 will control the clamping plates II22 on the front and rear sides to move away from each other, so that the clamping plates II22 release the magnets, and the controller 101 will control the electric push rod II14 to start working, the electric push rod II14 can drive the lifting plate 13 to descend and reset, the lifting plate 13 can drive the servo motor 15, the connecting plate 16 and the installation frame 4 to descend and reset, the magnet sheet will descend synchronously with the installation frame 4 due to gravity, so that the magnet sheet is separated from the cutting line of the multi-wire cutting machine body 3, when the installation frame 4 is completely reset, the controller 101 will control the electric push rod II14 to stop working, and the controller 101 will control the servo motor 15 to drive the connecting plate 16 to rotate One hundred and eighty degrees, the connecting plate 16 can drive the installation frame 4 to rotate one hundred and eighty degrees to dump the magnet pieces on the top of the installation frame 4 into the receiving frame 10. Some magnet pieces may also fall directly into the receiving frame 10 during the synchronous descending process with the installation frame 4. Then the magnet pieces can slide forward along the inclined surface at the bottom of the receiving frame 10 and be collected manually. At the same time, the controller 101 will control the electric push rod Ⅰ8 to drive the sliding plate 7 to retract into the installation frame 4 to prevent the magnet pieces from being clamped between the two sliding plates 7. Then the controller 101 will control the servo motor 15 to drive the connecting plate 16 to rotate one hundred and eighty degrees to reset. The connecting plate 16 can drive the installation frame 4 to rotate one hundred and eighty degrees to reset. Finally, the controller 101 will control the hydraulic cylinder 2 to drive the multi-wire cutting machine body 3 to descend and reset.

[0030] Since the width of the sliding plate 7 is small, when the mounting frame 4 rotates to dump the magnet sheet into the receiving frame 10, the magnet sheet will press the sliding plate 7, causing the sliding plate 7 to deform, thereby affecting the subsequent use of the sliding plate 7. Therefore, a clamping component is designed, such as Figure 6 As shown, the clamping assembly includes a fixed frame 27, a sliding clamp plate 28 and an electric push rod IV29. Four fixed frames 27 are spaced apart and connected to the front and rear sides of the mounting frame 4. A sliding clamp plate 28 is slidably connected between the upper parts of the four fixed frames 27. An electric push rod IV29 is connected to each fixed frame 27, and the telescopic rod of the electric push rod IV29 is connected to the sliding clamp plate 28.

[0031] When the mounting frame 4 is rising, the mounting frame 4 can drive the fixing frame 27 and the sliding clamping plate 28 to rise. When the top of the mounting frame 4 contacts the bottom of the magnet, the top of the sliding clamping plate 28 just contacts the bottom of the clamping plate II 22. Since the sum of the height of the clamping plate II 22 and the height of the clamping plate I 21 is less than the height of the magnet itself, the bottom of the magnet will protrude from the bottom of the clamping plate II 22. At this time, the two sliding clamping plates 28 are respectively located on the front and back sides of the magnet; when the magnet cutting is completed, the clamping plate I 21 and the clamping plate II 22 will both release the magnet. At this time, the controller 101 can control the electric push rod IV 29 to drive the two sliding clamping plates 28 to move to the side close to each other, so that the two sliding clamping plates 28 clamp the cut magnet sheet. When the mounting frame 4 is descending, the mounting frame 4 is lowered. The mounting frame 4 can drive the fixing frame 27 and the sliding clamp 28 to descend, and the sliding clamp 28 can drive the cut magnet sheet to move downward synchronously, ensuring that the cut magnet sheet is separated from the cutting line of the multi-wire cutting machine body 3; when the mounting frame 4 rotates one hundred and eighty degrees, the sliding clamp 28 can drive the cut magnet sheet to rotate one hundred and eighty degrees, and then the controller 101 will control the electric push rod IV29 to drive the two sliding clamps 28 to move away from each other, so that the sliding clamp 28 releases the magnet sheet. Only then will the magnet sheet fall down into the receiving frame 10 due to the action of gravity. In this way, the magnet sheet can be prevented from moving during the descent and rotation of the magnet sheet, thereby ensuring that the sliding plate 7 is not compressed and deformed by the magnet sheet.

[0032] When the existing multi-wire cutting machine body 3 cuts the magnet, it is usually equipped with a cutting fluid spraying system to cool down the cutting wire of the multi-wire cutting machine body 3. However, the existing cutting fluid spraying system sprays the cutting fluid onto the surface of the magnet, while the cutting wire of the multi-wire cutting machine body 3 is located inside the magnet, and the cutting wire of the multi-wire cutting machine body 3 moves very fast, so it is difficult to timely achieve a good cooling effect on the part where the cutting wire cuts the magnet. Therefore, a cooling component is designed; Figure 7 As shown, the cooling assembly includes a square frame 30, a hollow frame 31, a connecting head 32, a fixing rod 33 and a baffle 34. The square frame 30 is connected to the top of the installation frame 4. Three hollow frames 31 are spaced apart on the front and rear sides of the square frame 30. The bottom of each hollow frame 31 is connected to the connecting head 32. The fixing rods 33 are symmetrically connected to the front and rear sides of the top of the installation plate 6. A baffle 34 is connected between the upper parts of the two fixing rods 33 on the left side, and a baffle 34 is also connected between the upper parts of the two fixing rods 33 on the right side. There are two baffles 34, and the two baffles 34 are respectively located on the left and right sides of the installation frame 4. The left and right sides of the top of the square frame 30 are spaced apart by wire grooves 35, and the tops of the two baffles 34 are also spaced apart by wire grooves 35.

[0033] Initially, the cutting line of the multi-wire cutting machine body 3 is located in the wire groove 35; before the magnet is cut, it is necessary to manually connect the discharge pipe of the cutting fluid to the connector 32; when the mounting frame 4 is rising, the mounting frame 4 can drive the square frame 30 to rise until the top of the square frame 30 contacts the bottom of the magnet, and the mounting frame 4 and the frame 30 stop rising. At this time, the top of the mounting frame 4 does not contact the bottom of the magnet, and a liquid storage space is formed between the top of the mounting frame 4, the bottom of the magnet and the inner side of the square frame 30. Through the guiding effect of the connector 32 and the hollow frame 31, the cutting fluid can enter the above-mentioned liquid storage space; and the multi-wire cutting machine body 3 will continue to rise to cut the magnet, and the cutting line of the multi-wire cutting machine body 3 will be separated from the wire groove 35 at the top of the square frame 30. Since the mounting plate 6 will be connected to the multi-wire cutting machine The main body 3 rises synchronously, and the mounting plate 6 can drive the fixing rod 33 and the baffle 34 to rise, so that the two baffles 34 respectively block the left and right sides of the magnet, and the cutting line of the multi-wire cutting machine main body 3 will continue to pass through the wire groove 35 on the top of the baffle 34; because the two adjacent sets of sliding plates 7 are arranged at intervals, the cutting fluid in the liquid storage space can enter the cutting seam along the cutting path of the magnet, and the baffle 34 blocks the left and right sides of the magnet, which can prevent the cutting fluid from overflowing from the left and right sides of the cutting seam, so that the cutting fluid can fill the cutting seam of the magnet, and the cutting fluid in the cutting seam can slowly flow out along the wire groove 35 on the top of the baffle 34, so as to achieve a better cooling effect on the part where the cutting line cuts the magnet, and the flowing cutting fluid can be collected and utilized (the prior art will not be described in detail).
