Description

Technical Field

[0001] The present invention relates to the technical field of magnetic core cutting equipment, in particular to a magnetic core cutting equipment and a cutting method. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. The magnetic core is used in coils and transformers of various electronic devices. The magnetic cores in transformers include pot cores, RM cores, E cores, EC, ETD and EER cores, PQ cores, EP cores, EP cores, toroidal cores and other cores. The reason why the magnetic cores have these different shapes is generally completed through core cutting equipment.

[0003] The magnetic core cutting equipment commonly used in the market is generally driven by an electric push rod to push the magnetic core to the bottom of the cutting knife.

However, in the process of cutting the magnetic core, such as the common annular magnetic cores on the market, not all annular magnetic cores need to be completely cut. Some need to be opened. As a result, when opening the annular magnetic core, the general cutting equipment needs to first load the material and make the first cut, then unload the material, and manually calibrate and turn, and then make the second cut to complete the opening of the annular magnetic core.

[0012] A magnetic core cutting device and a cutting method, using the magnetic core cutting device described above, the magnetic core cutting device and the cutting method include the following steps: A1: After placing the annular magnetic core on the top of the tray, start the electric telescopic rod through the controller. After the electric telescopic rod is pushed out, the clamping plate and the positioning column are driven to move toward the annular magnetic core.

During the rotation, the fan blade performs air cooling on the blade. A4: After the annular core is cut, the tray moves to the water baffle. At this time, the servo motor is started again through the controller to maintain the clamping state of the clamping plate and the positioning column. When the servo motor is started, the tray drives the brush to rotate, and the brush drives the stand and the first spring to rotate. The first spring cleans the inner wall of the annular core during the rotation.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The magnetic core cutting equipment and cutting method first place the annular magnetic core on the top of the tray, start the electric telescopic rod to push out through the controller, the electric telescopic rod drives the clamp and the positioning column to clamp the annular magnetic core, then control the electric slide rail to start, and send the tray and the annular magnetic core on the top to the bottom of the cutting machine through the electric slide rail for cutting, when the annular magnetic core needs to be opened and the cutting angle is adjusted, control the electric telescopic rod to return, release the fixation of the annular magnetic core, and then start the servo motor, drive the tray and the annular magnetic core to rotate through the servo motor, after the steering adjustment is completed, control the electric telescopic rod to push out again, fix the annular magnetic core through the clamp and the positioning column, and then control the servo motor to drive the tray to reset, and then drive the tray and the annular magnetic core to the bottom of the cutting machine and cut through the electric slide rail again, thereby improving the convenience of steering when the annular magnetic core is opened and cut, and avoiding the process of frequent loading and unloading and manual steering.

[0014] 2.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0017] See also Figure 1-11A magnetic core cutting device comprises a base 1 and a cutting machine, wherein the cutting machine is located on the top of the base 1 and is controlled by a controller, a protective cover 11 is fixed on the top of the base 1, a spray pipe is arranged inside the protective cover 11 and the spray pipe is controlled by the controller, a directional slide groove 2 is arranged inside the bottom end of the base 1, and side slide grooves 3 are arranged inside the two sides of the base 1; An electric slide rail 4 is fixed inside the directional slide groove 2, a sliding seat 41 is slidably sleeved outside the electric slide rail 4, a servo motor 42 is fixed inside the sliding seat 41, and a clamping assembly is provided outside the output end of the servo motor 42, and the clamping assembly is used to clamp and fix the magnetic core; The clamping assembly includes a tray 5, which is used to place the annular magnetic core. A cutting groove 51 is opened on the top of the tray 5. Stands 54 are fixed on both sides of the cutting groove 51 on the top of the tray 5. A first spring 55 is fixed on the side of the stand 54 away from the cutting groove 51. A push rod 56 is fixed to the outside of one end of the first spring 55. A sliding frame 6 is rotatably sleeved on the outside of the tray 5. Both sides of the sliding frame 6 are slidably sleeved inside the side slide groove 3. Electric telescopic rods 62 are fixed on both sides of the top of the sliding frame 6, and the electric telescopic rod 62 is located inside the side slide groove 3. A clamping plate 63 is fixed on the outside of the output end of the electric telescopic rod 62, and a positioning column 64 is fixed on the side of the clamping plate 63 away from the electric telescopic rod 62. The height of the stand 54 is consistent with the height of the clamping plate 63, the outer portion of the top rod 56 is arranged in an arc shape, the inner portion of the protective cover 11 close to the cutting machine is hinged with a water baffle 12, and drainage ports are provided inside both sides of the base 1 for discharging the accumulated water inside the directional chute 2 and the side chute 3; During the specific operation, the annular magnetic core is first placed on the top of the tray 5, and the annular magnetic core is sleeved on the outside of the ejector rod 56. The first spring 55 gives the ejector rod 56 a force to reset, so that the annular magnetic core is initially fixed by the two groups of ejector rods 56. Then, the electric telescopic rod 62 is started by the controller, and the clamping plate 63 and the positioning column 64 are driven to move toward the annular magnetic core by the ejection of the electric telescopic rod 62, and the annular magnetic core is clamped in the middle of the positioning column 64, thereby completing the clamping and fixing of the annular magnetic core, avoiding the annular magnetic core from being offset during cutting, and improving the stability of the annular magnetic core during cutting. When the annular magnetic core is fixed, the electric slide rail 4 is started through the controller, and the electric slide rail 4 drives the sliding seat 41 and the servo motor 42 to move toward the cutting machine, and the servo motor 42 drives the tray 5 to move synchronously. Since the tray 5 is sleeved inside the sliding frame 6, when the tray 5 moves toward the cutting machine, the tray 5 drives the sliding frame 6 and the annular magnetic core to move synchronously, and then the cutting machine is started. As the annular magnetic core gradually approaches the cutting machine, until the annular magnetic core contacts the cutting knife, the cutting knife enters the cutting groove 51 and cuts the annular magnetic core along the cutting groove 51. The space reserved by the cutting groove 51 ensures that the cutting knife has enough cutting space. Furthermore, when the annular magnetic core needs to be opened, after the first cut is completed, the electric slide rail 4 is controlled to return, so that the electric slide rail 4 drives the tray 5 and the annular magnetic core to separate from the cutting knife, and then the electric telescopic rod 62 is controlled to return through the controller, so that the clamping plate 63 and the positioning column 64 lose the clamping limit on the annular magnetic core, and then the servo motor 42 is controlled to start through the controller, and the rotation angle of the servo motor 42 is controlled according to the cutting requirements. During the rotation process, the servo motor 42 drives the tray 5 to synchronously turn and adjust, and during the turning and adjusting process, the tray 5 drives the annular magnetic core on its top to turn synchronously; When the annular magnetic core rotates to the specified angle, the electric telescopic rod 62 is controlled to be pushed out again, and the clamping plate 63 and the positioning column 64 clamp the annular magnetic core again, so that the annular magnetic core is fixed and limited, and then the servo motor 42 is controlled to reset, and the servo motor 42 drives the tray 5 to reset synchronously, so that the directions of the cutting groove 51 and the directional slide groove 2 are restored to be consistent, and then the electric slide rail 4 can be started again, and the tray 5 and the annular magnetic core are driven by the electric slide rail 4 to move toward the cutting machine again, and the second cutting is performed. After the second knife cutting, the annular magnetic core is opened, thereby reducing the number of times the annular magnetic core is loaded and unloaded. At the same time, under the action of the motor control steering, the accuracy and convenience of angle adjustment are improved, thereby improving the efficiency of cutting or opening the annular magnetic core; After the cutting is completed, the tray 5 and the annular magnetic core on its top are continued to be moved toward the water baffle 12 by the electric slide rail 4, and after the tray 5 touches the water baffle 12, the water baffle 12 is pushed to flip over so that the tray 5 and the annular magnetic core are exposed to the outside of the entire device, and then the annular magnetic core can be taken out.

[0018] It should be noted that each group of positioning posts 64 is composed of two semi-cylinders. Since the shape of the annular magnetic core is a circular ring, when the two groups of positioning posts 64 clamp the annular magnetic core, the stability of the annular magnetic core is guaranteed when it is subjected to the cutting force of the cutting knife, and the annular magnetic core is prevented from shifting left and right, or forward and backward, thereby improving the stability of the annular magnetic core during cutting. Example

[0019] A support frame 7 is fixed to the outside of the sliding frame 6 away from the cutting machine, and a material passing trough 71 is provided inside the support frame 7. Rotating brackets 72 are fixed to the inner walls on both sides of the support frame 7. A cleaning roller 73 is rotatably sleeved on the outside of the rotating bracket 72. A support plate 8 is fixed to the top of the support frame 7 away from the cutting machine. A fan blade 81 is rotatably sleeved inside the support plate 8. A belt 82 is connected to the external transmission sleeve of one end of the fan blade 81, and the external transmission sleeve of the rotating bracket 72 on the side away from the cutting machine is transmission sleeved with the belt 82. Specifically, when the electric slide rail 4 is started, it drives the sliding seat 41, the servo motor 42 and the tray 5 to move toward the cutting machine. During the movement, the tray 5 drives the sliding frame 6 and the support frame 7 to move toward the cutting machine. When the support frame 7 moves toward the cutting machine, the support frame 7 drives the rotating bracket 72 and the cleaning roller 73 to move toward the cutting machine until the cutting knife of the cutting machine completes the cutting of the annular magnetic core and the cutting knife passes through the cutting groove 51 and enters the inside of the feeding groove 71. When the cutting blade enters the inside of the feeding trough 71, it contacts the two sets of cleaning rollers 73. At this time, the cutting machine is controlled to drive the cutting blade to rotate. During the rotation of the cutting blade, the cleaning rollers 73 are driven to rotate. During the rotation of the two sets of cleaning rollers 73, the front and back sides of the cutting blade are cleaned. When the cutting blade surface cuts the annular magnetic core, the remaining debris and mud are cleaned up. The cleaned cutting blade improves the efficiency of subsequent cutting of the annular magnetic core, and the scraped debris and mud fall into the bottom of the feeding trough 71. Furthermore, when the cleaning roller 73 on the side away from the cutting machine rotates, the cleaning roller 73 drives the belt 82 to rotate, and the belt 82 drives the fan blade 81 to rotate. During the rotation process, the fan blade 81 performs air cooling operation on the cutting knife, and in combination with the spray pipe, performs a cooling operation on the cutting knife, thereby reducing the damage to the cutting knife caused by the heat generated when the cutting knife cuts the annular magnetic core, and prolonging the service life of the cutting knife; Furthermore, as the electric slide rail 4 continues to transport, the tray 5 drives the support frame 7 to continuously move toward the direction of the water baffle 12, so that the cleaning roller 73 moves along the directional slide groove 2 toward the water baffle 12. During the movement, the area and position of the cleaning roller 73 in contact with the cutting knife continuously change, so that the cleaning position of the cleaning roller 73 gradually moves from the edge of the cutting knife toward the direction of the cutting machine rotating shaft, so that the cleaning area of ​​the cleaning roller 73 for the cutting knife gradually increases, thereby improving the comprehensiveness of the cleaning of the cutting knife; At the same time, as the support frame 7 moves, the fan blades 81 move synchronously toward the water baffle 12, so that the wind direction blown by the fan blades 81 is constantly changing, thereby increasing the contact area between the wind blown by the fan blades 81 and the cutting knife, thereby improving the cooling effect on the cutting knife, and further improving the service life of the cutting knife. When the fan blades 81 move to the position of the cutting machine, the coolant sprayed by the spray pipe is sprayed on the surface of the fan blades 81, and under the action of the rotation of the fan blades 81, the coolant is thrown toward the cutting knife, further improving the cooling effect of the cutting knife.

[0020] It should be noted that the height of the support frame 7 is lower than the height of the cutting machine's rotating shaft, and the height of the cleaning roller 73 is also lower than the height of the cutting machine's rotating shaft, ensuring that the cleaning roller 73 will not contact the cutting machine's rotating shaft during movement, thereby ensuring the stability of the cutting machine's rotation. At the same time, the spray port of the spray pipe is directed toward the bottom of the cutting knife, ensuring timely cooling of the cutting knife when cutting the annular magnetic core. Example

[0021] An embedded groove 61 is formed inside the bottom of the sliding frame 6, and the tray 5 is rotatably sleeved inside the embedded groove 61. Openings are formed on both sides of the embedded groove 61. A magnetic sheet 52 is fixed to the outside of the tray 5. A brush 53 is fixed to the outside of the magnetic sheet 52. The magnetic sheet 52 and the brush 53 are located inside the embedded groove 61, and the brush 53 contacts the inner wall of the embedded groove 61. A second spring 74 is fixed to the inner wall of the feeding trough 71 near the sliding frame 6, and a magnetic plate 75 is fixed to one end of the second spring 74. The second spring 74 is sleeved inside the magnetic plate 75. The top of the magnetic plate 75 is inclined. The magnetic properties of the magnetic plate 75 and the magnetic sheet 52 are the same. Openings are provided on both sides of the top of the sliding frame 6, and the width of the openings is consistent with the width of the cutting groove 51. Specifically, when the annular magnetic core is cut and the cutting knife is cleaned, the electric slide rail 4 is controlled to drive the sliding seat 41, the servo motor 42 and the tray 5 to move toward the direction of the water baffle 12 until the annular magnetic core passes through the cutting knife and part of the cutting knife remains inside the cutting groove 51, and then the servo motor 42 is started again, and the tray 5 is driven to rotate again by the servo motor 42. During the rotation of the tray 5, the stand 54 is driven to rotate synchronously, and the stand 54 drives the first spring 55 and the push rod 56 to rotate inside the annular magnetic core. During the rotation, the push rod 56 cleans the inner wall of the annular magnetic core, thereby reducing the subsequent labor of cleaning the annular magnetic core. Furthermore, during the cutting process, the debris and mud generated by cutting the annular magnetic core falls into the inside of the cutting groove 51. Since the servo motor 42 drives the tray 5 to rotate, the debris and mud remaining in the cutting groove 51 during the rotation of the tray 5 are thrown away by the centrifugal force generated by the rotation of the tray 5 and the cooperation of the spraying of the spray pipe, and fall into the embedded groove 61. At the same time, during the rotation of the tray 5, the magnetic sheet 52 and the brush 53 are driven to rotate synchronously. During the rotation of the brush 53, the debris and mud falling into the embedded groove 61 are swept out through the openings on both sides of the embedded groove 61, thereby achieving the effect of removing the debris and mud inside the cutting groove 51. At the same time, the magnetic sheet 52 gradually approaches the magnetic plate 75 inside the feeding chute 71 during the rotation process. When the magnetic sheet 52 and the magnetic plate 75 are close to each other, under the effect of like charges repelling each other, the magnetic sheet 52 pushes the magnetic plate 75 to move in the direction of the belt 82, and the mud and debris are shoveled out from the inside of the feeding chute 71. Then, during the continuous rotation of the magnetic sheet 52, the distance between the magnetic plate 75 and the magnetic plate 75 is gradually increased, and the repulsive force between the magnetic plate 75 and the magnetic plate 75 is gradually reduced. The magnetic plate 75 is instantly reset under the action of the second spring 74, and during the reset process, The magnetic plate 75 touches the inner wall of the trough 71, and then when the top of the magnetic plate 75 is tilted, the magnetic plate 75 vibrates after contacting the trough 71, and the mud and debris slide from the top of the magnetic plate 75 to the bottom of the trough 71 under the action of gravity, and the inside of the trough 71 is repeatedly cleaned under the continuous cyclic rotation of the magnetic plate 52, so that the magnetic plate 75 shovels the debris and mud in the trough 71 to the outside, and the shoveled debris and mud fall into the inside of the directional chute 2 and are discharged through the drain port; Furthermore, when the push rod 56 cleans the inner wall of the annular magnetic core during the rotation process, the push rod 56 will contact the cutting knife. Since the push rod 56 is elastically connected to the first spring 55, and the push rod 56 is made of rubber and the outer part of the push rod 56 is arranged in an arc shape, the push rod 56 and the cutting knife are in flexible contact. When the push rod 56 rotates with the tray 5, the push rod 56 cyclically contacts the cutting knife and vibrates the cutting knife. With the cooperation of the cleaning roller 73, the cleaning effect of the cutting knife is enhanced, so that the residual debris and mud on the surface of the cutting knife are shaken off. At the same time, under the action of the first spring 55, the push rod 56 vibrates when in contact with the cutting knife, generating continuous vibrations. During the rotation process, the push rod 56 in continuous vibration continuously contacts the annular magnetic core, thereby achieving the purpose of shaking off the mud and debris on the inner wall surface of the annular magnetic core, thereby enhancing the cleaning effect on the inner wall of the annular magnetic core.

After the electric telescopic rod 62 is pushed out, the clamping plate 63 and the positioning column 64 are driven to move toward the annular magnetic core. Under the action of the two groups of positioning columns 64 and the clamping plate 63, the annular magnetic core is supported and fixed. Then the electric slide rail 4 is started, and the tray 5 and the annular magnetic core are driven by the electric slide rail 4 to move toward the direction of the cutting machine, and the cutting of the annular magnetic core is completed; A2: When the cutting angle of the annular magnetic core needs to be adjusted, the controller controls the electric telescopic rod 62 to return, so that the clamping plate 63 and the positioning column 64 release the support of the annular magnetic core, and then controls the servo motor 42 to start, and the servo motor 42 drives the tray 5 to adjust the internal rotation of the embedded groove 61, and the tray 5 drives the annular magnetic core to adjust the rotation synchronously. When the angle adjustment of the annular magnetic core is completed, the electric telescopic rod 62 is controlled to be ejected again, the annular magnetic core is clamped and limited again, and subsequent cutting is performed; A3: When the annular magnetic core is continuously cut, the cleaning roller 73 gradually moves toward the blade of the cutter. When the blade of the cutter enters the inside of the feeding trough 71, the front and back sides of the blade contact with the two groups of cleaning rollers 73 and clean the blade. The cleaning roller 73 away from the cutter rotates under the drive of the blade. During the rotation, the transmission belt 82 drives the fan blade 81 to rotate. During the rotation, the fan blade 81 performs air cooling operation on the blade. A4: When the annular magnetic core is cut, the tray 5 moves to the water baffle 12. At this time, the servo motor 42 is started again by the controller, and the clamping state of the clamping plate 63 and the positioning column 64 is maintained. When the servo motor 42 is started, the tray 5 drives the brush 53 to rotate, and the brush 53 drives the stand 54 and the first spring 55 to rotate. The first spring 55 cleans the inner wall of the annular magnetic core during the rotation.

8. A magnetic core cutting device and a cutting method, using the magnetic core cutting device as claimed in claim 7, characterized in that: The following steps are involved: A1: After placing the annular magnetic core on the top of the tray (5), the electric telescopic rod (62) is activated through the controller. The electric telescopic rod (62) is pushed out to drive the clamping plate (63) and the positioning column (64) to move toward the annular magnetic core. Under the action of the two groups of positioning columns (64) and the clamping plate (63), the annular magnetic core is supported and fixed. Then, the electric slide rail (4) is activated to drive the tray (5) and the annular magnetic core to move toward the cutting machine through the electric slide rail (4), and the magnetic core cutting is completed; A2: When the cutting angle of the annular magnetic core needs to be adjusted, the controller controls the electric telescopic rod (62) to return, so that the clamping plate (63) and the positioning column (64) release the clamping of the annular magnetic core, and then controls the servo motor (42) to start, and the servo motor (42) drives the tray (5) to adjust the internal rotation of the embedded groove (61), and the tray (5) drives the annular magnetic core to adjust the rotation synchronously. When the angle adjustment of the annular magnetic core is completed, the electric telescopic rod (62) is controlled to be ejected again, and the annular magnetic core is clamped and limited again, and subsequent cutting is performed; A3: When the annular magnetic core is continuously cut, the cleaning roller (73) gradually moves toward the blade of the cutting machine. When the blade of the cutting machine enters the inside of the material trough (71), the front and back sides of the blade contact the two groups of cleaning rollers (73) and clean the blade. The cleaning roller (73) away from the cutting machine is driven by the blade to rotate. During the rotation, the transmission belt (82) drives the fan blade (81) to rotate. During the rotation, the fan blade (81) performs air cooling on the blade. A4: After the annular magnetic core is cut, the tray (5) moves to the water baffle (12). At this time, the servo motor (42) is controlled by the controller to start again, and the clamping state of the clamping plate (63) and the positioning column (64) is maintained. When the servo motor (42) is started, the tray (5) drives the brush (53) to rotate, and the brush (53) drives the stand (54) and the first spring (55) to rotate. The first spring (55) cleans the inner wall of the annular magnetic core during the rotation process.
