Description

Technical Field

[0001] The present invention relates to the technical field of magnetic core processing, and in particular, to a magnetic core forming die, a forming device, and a manufacturing process. Background Art

[0002] Currently, when processing magnetic cores, stamping is often used. The general process for stamping magnetic cores is as follows: First, the magnetic core raw material is cut to obtain a magnetic core shape suitable for processing, and then the cut magnetic core is placed into an extrusion mechanism, and the extrusion mechanism extrudes the magnetic core to form a magnetic core.

[0003] In the related art, the following problems have been found: The die provided on the extrusion mechanism is prone to adhesion to the magnetic core, which will result in a low processing yield of the magnetic core, and at the same time, there are also safety hazards in the processed magnetic core. Based on this, in some stamping solutions, a lubricant is applied to the magnetic core before stamping, and the applied lubricant can reduce the phenomenon of adhesion between the die and the magnetic core to improve the yield of the magnetic core.

[0004] In view of the above related art, the following defects have been found: When applying the lubricant to the surface of the magnetic core, it is necessary to manually apply the lubricant to both sides of the magnetic core respectively. This will correspondingly increase labor and material resources, and thus increase the processing cost of the magnetic core. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and to provide a magnetic core forming die, a forming device, and a manufacturing process, which can reduce the stamping cost of the magnetic core while improving the processing quality of the magnetic core.

[0006] According to the first aspect of the present invention, a magnetic core forming die is provided. The forming die includes a forming frame body, an upper stamping die, a lower stamping die, and a driving component; The lower stamping die is arranged on the forming frame body; The upper stamping die is slidably connected to the forming frame body through the driving component. Among them, the upper stamping die and the lower stamping die form a stamping space for the magnetic core; The driving component is used to drive the upper stamping die to approach the lower stamping die.

[0007] Through the above solution, when forming and processing the magnetic core, the driving component is adjusted, and the driving component drives the upper stamping die to move. The upper stamping die approaches the lower stamping die, and the stamping of the magnetic core is realized under the interaction of the upper stamping die and the lower stamping die.

[0008] According to the second aspect of the present invention, a magnetic core forming device is provided. The forming device further includes a first coating mechanism, a second coating mechanism, and a flipping mechanism; The first coating mechanism is arranged on one side of the forming frame body and is used for coating lubricant on one side of the magnetic core; The flipping mechanism is arranged between the first coating mechanism and the stamping die. The flipping mechanism is used to drive the magnetic core to flip so that the uncoated side of the magnetic core is exposed; The second coating mechanism is arranged between the flipping mechanism and the stamping die and is used for coating lubricant on the other side of the magnetic core.

[0009] Through the above scheme, when stamping the magnetic core, the cut magnetic core raw material is placed on the first coating mechanism, and the first coating mechanism is started. The first coating mechanism coats lubricant on one side of the magnetic core and drives the magnetic core to move on it. When the magnetic core moves onto the flipping mechanism, the flipping mechanism is started. The flipping mechanism clamps the magnetic core on the first coating mechanism. When the clamping of the magnetic core is completed, the flipping mechanism flips and transports the magnetic core onto the second coating mechanism. At this time, the uncoated side of the magnetic core is exposed. The second coating mechanism is started, and the second coating mechanism coats the uncoated side of the magnetic core. When both sides of the magnetic core are coated, the magnetic core is transported into the stamping space for forming operation on the magnetic core. By coating lubricant on both sides of the magnetic core, the coated lubricant can reduce the phenomenon that the upper stamping die and the lower stamping die will directly contact the magnetic core and damage the magnetic core when the forming die stamps the magnetic core, and at the same time prevent the phenomenon of adhesion between the upper stamping die and the lower stamping die and the magnetic core, so as to improve the stamping quality of the magnetic core.

[0010] Optionally, the first coating mechanism includes a first coating bracket, a first transmission assembly, a first grasping assembly and a first loading platform; The first coating bracket is arranged on one side of the forming frame body; The first transmission assembly is arranged on the first coating bracket and is used for transporting the magnetic core on the first coating bracket; The first loading platform is arranged on one side of the first coating bracket, and there is lubricant on the first loading platform; The first grasping assembly is used for applying lubricant to one side of the magnetic core located on the first transmission assembly.

[0011] Through the above technical scheme, the magnetic core is placed on the first transmission assembly. The first transmission assembly drives the magnetic core to move on the first coating bracket. At the same time, the first grasping assembly is adjusted, and the first grasping assembly applies the lubricant on the first loading platform to the magnetic core, realizing the operation of coating lubricant on one side of the magnetic core.

[0012] Optionally, the flipping mechanism includes a flipping bracket, at least two flipping arms, a power assembly and a clamping assembly; The first coating bracket has a feeding end, and the flipping bracket is arranged on one side of the feeding end; The flipping arm is rotatably connected to the flipping bracket through the power assembly, wherein at least two flipping arms are symmetrically arranged along the length direction of the flipping bracket; The clamping assembly is arranged on the flipping arm, and the clamping assembly is used for clamping the magnetic core; The power assembly is used to simultaneously drive the symmetrically arranged flipping arms to rotate so as to flip the magnetic core.

[0013] Through the above technical solution, when one side of the magnetic core is coated by the first coating mechanism, the magnetic core continues to move on the first coating bracket under the action of the first transportation assembly. When the magnetic core moves to the feeding end, the flipping arm is adjusted. The flipping arm flips to the feeding end, the clamping assembly is turned on, and the clamping assembly clamps the magnetic core at the feeding end. The flipping arm is further adjusted, and the flipping arm performs a flipping operation on the magnetic core. The magnetic core is flipped so that its uncoated side is exposed, and the magnetic core is transported to the second coating mechanism. The second coating mechanism is turned on, and the second coating mechanism performs a coating operation on the uncoated side of the magnetic core. With such a setting, the flipping arms symmetrically arranged along the flipping bracket can flip the magnetic core. At the same time, the symmetrically arranged flipping arms flip simultaneously to prevent the magnetic core from being torn and damaged during the flipping process; further, a clamping assembly is arranged on the flipping arm. On the one hand, it can realize the clamping of the magnetic core to prevent the magnetic core from falling when the flipping arm flips the magnetic core. On the other hand, the arranged clamping assembly can make the lubricant evenly coated on the magnetic core, thereby improving the subsequent forming quality of the magnetic core.

[0014] Optionally, the power assembly includes a power motor, a first driving wheel, a second driving wheel, a third driving wheel, a fourth driving wheel, a first driving member, a second driving member, a third driving member and a connecting rod; The first driving wheel is rotatably connected to the flipping bracket, and the first driving wheel is connected to the power motor through the first driving member; The power motor is used to drive the first driving wheel to rotate through the first driving member; One end of the connecting rod is connected to the first driving wheel, wherein the axial direction of the connecting rod is perpendicular to the length direction of the flipping bracket; The second driving wheel is rotatably connected to the flipping bracket, the second driving wheel is connected to the first driving wheel through the second driving member, and one side of the flipping arm is connected to the second driving wheel; The third driving wheel is connected to the other end of the connecting rod and is rotatably connected to the flipping bracket; The fourth driving wheel is connected to the third driving wheel through the third driving member, and the turning arm on the other side of the turning bracket is connected to the fourth driving wheel.

[0015] Through the above technical solution, after the clamping assembly clamps the magnetic core, the power motor is started. The power motor drives the first driving member to move, the first driving member drives the first driving wheel to rotate, the rotation of the first driving wheel causes the second driving member to move, the movement of the second driving member drives the second driving wheel to move, and the rotation of the second driving wheel drives the turning arm on one side of the turning bracket to rotate. At the same time, the rotation of the first driving wheel drives the connecting rod to move. At this time, the connecting rod rotates, and the rotation of the connecting rod drives the third driving wheel to rotate. The rotation of the third driving wheel drives the third driving member to move, and the movement of the third driving member drives the fourth driving wheel to rotate. The rotation of the fourth driving wheel causes the turning arm on the other side of the turning bracket to rotate, achieving the purpose of synchronous movement of the symmetrically arranged turning arms.

[0016] Optionally, the clamping assembly includes a first clamping wheel, a second clamping wheel, a first driving member, and a second driving member; There are multiple first clamping wheels, and the multiple first clamping wheels are arranged along the length direction of the turning arm; There are multiple second clamping wheels, and the multiple second clamping wheels are arranged along the length direction of the turning arm. Wherein, the first clamping wheel and the second clamping wheel form a clamping space for the magnetic core, and the size of the clamping space is variable; The first driving member is used to drive the first clamping wheel to rotate; The second driving member is used to drive the second clamping wheel to approach the first clamping wheel.

[0017] Through the above technical solution, when the magnetic core moves to the blanking end, due to a certain inertia, the magnetic core will move forward for a certain distance. At this time, the turning arm moves to the blanking end, and the magnetic core will extend into the clamping space. The first driving member and the second driving member are started. The first driving member drives the first clamping wheel to rotate, and the rotation of the first clamping wheel causes the magnetic core to move forward in the clamping space. The second driving member drives the second clamping wheel to approach the first clamping wheel. At this time, the clamping space shrinks, and both the first clamping wheel and the second clamping wheel are in contact with the magnetic core. In this way, while driving the magnetic core to move forward, the coating between the magnetic core and the lubricant can be made more uniform. When the magnetic core moves to an appropriate position, the second driving member is further adjusted, the second clamping wheel approaches the first clamping wheel further, and the first clamping wheel and the second clamping wheel clamp the magnetic core for subsequent turning of the magnetic core.

[0018] Optionally, the first driving member includes a driving motor, a driving belt, and a driving wheel; There are multiple driving wheels, which are rotatably connected to the flipping arm, and the multiple driving wheels are correspondingly connected to the first clamping wheels; The driving belt is used to connect adjacent driving wheels; The driving motor is used to drive any one of the driving wheels to rotate.

[0019] Through the above technical solution, when the magnetic core moves into the clamping space, the driving motor is turned on. The driving motor rotates to drive any one of the driving wheels to rotate. Any one of the driving wheels rotates to drive the driving belt to move. Under the action of the driving belt, multiple driving wheels are driven to rotate. The rotation of the driving wheels drives the corresponding first clamping wheels to rotate. In this way, multiple first clamping wheels can rotate, so that the magnetic core can move in the clamping space until it moves to a suitable position.

[0020] Optionally, the second driving member includes a first electromagnet, a second electromagnet and a return spring; Multiple second clamping wheels are slidably connected to the flipping arm, and the second clamping wheels can rotate on the flipping arm; There are multiple first electromagnets, and the multiple first electromagnets are connected to the second clamping wheels; The second electromagnet is arranged on the flipping arm through the return spring; The return spring is used to drive the second electromagnet to return to its original position.

[0021] Through the above technical solution, when it is necessary to drive the second clamping wheel to approach the first clamping wheel, the first electromagnet and the second electromagnet are energized. At this time, the mutually approaching sides of the first electromagnet and the second electromagnet repel each other. The first electromagnet moves away from the second electromagnet. The movement of the first electromagnet drives the second clamping wheel to move, and the second clamping wheel approaches the first clamping wheel to clamp the magnetic core. When it is necessary to drive the magnetic core to move in the clamping space and move the magnetic core to the second coating mechanism, the first electromagnet and the second electromagnet are energized. At this time, the mutually approaching sides of the first electromagnet and the second electromagnet attract each other. At this time, the first clamping wheel and the second clamping wheel move away from each other to facilitate the movement of the magnetic core in the clamping space.

[0022] Optionally, the second coating mechanism includes a second coating bracket, a second transmission component, a second grasping component and a second carrier; The second coating bracket is arranged on the side of the flipping bracket away from the first coating bracket; The second transmission component is arranged on the second coating bracket and is used to transport the magnetic core on the second coating bracket; The second carrier is arranged on one side of the second coating bracket, and there is a lubricant on the second carrier; The second grasping component is used to apply lubricant to one side of the magnetic core located on the second transmission component.

[0023] Through the above technical solution, when the magnetic core is driven by the flipping mechanism to the second coating mechanism, under the action of the flipping mechanism, the magnetic core is placed on the second transmission component. The second transmission component drives the magnetic core to move on the second coating bracket. At the same time, the second grasping component is adjusted, and the second grasping component applies lubricant to one side, achieving the purpose of applying lubricant to both sides of the magnetic core.

[0024] According to the third aspect of the present invention, a manufacturing process for magnetic cores is provided. The manufacturing process includes: S1: Place the magnetic core raw material on the first coating mechanism and apply lubricant to one side of the magnetic core raw material; S2: Under the action of the flipping mechanism, the magnetic core raw material is flipped to the second coating mechanism; S3: Place the magnetic core raw material on the second coating mechanism and apply lubricant to the other side of the magnetic core raw material; S4; The feeding mechanism sends the magnetic core raw material to the molding die for molding.

[0029] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0030] This application provides a magnetic core forming die, a forming device, and a manufacturing process. The magnetic core forming die, the forming device, and the manufacturing process are introduced in detail as follows.

[0031] First of all, it should be noted that in the magnetic core forming, for example, when pressing magnetic powders (such as ferrite, metal magnetic powder cores), a small amount of lubricants (such as zinc stearate, paraffin, etc.) are usually added. This application will not introduce this in detail.

[0032] In some embodiments of the present invention, the forming die 1 includes a forming frame body 11, an upper stamping die 12, a lower stamping die 13, and a driving component 14; the lower stamping die 13 is installed on the forming frame body 11; the upper stamping die 12 is slidably connected to the forming frame body 11 through the driving component 14, wherein a stamping space for the magnetic core is formed between the upper stamping die 12 and the lower stamping die 13; the driving component 14 is used to drive the upper stamping die 12 to approach the lower stamping die 13. It can be understood that the function of the driving component 14 is to drive the upper stamping die 12 to approach the lower stamping die 13 to achieve the purpose of stamping the magnetic core. This structure is well-known to those skilled in the art, and this application will not elaborate here.

[0033] As an example, the driving component 14 can be set as an oil cylinder. The first coating mechanism 2 is arranged on one side of the forming frame body 11 for coating one side of the magnetic core with lubricant; the flipping mechanism 4 is arranged between the first coating mechanism 2 and the forming frame body 11; the second coating mechanism 3 is arranged between the flipping mechanism 4 and the forming frame body 11 for coating the uncoated side of the magnetic core.

[0034] Specifically, when the magnetic core needs to be stamped, the magnetic core is placed in the stamping space, the driving component 14 is started, and the driving component 14 drives the upper stamping die 12 to approach the lower stamping die 13, and the stamping of the magnetic core is realized under the cooperation of the upper stamping die 12 and the lower stamping die 13. It should be noted that for body magnetic cores of different specifications, upper stamping dies 12 and lower stamping dies 13 of different specifications can be used. This application will not elaborate here.

[0035] The relevant introduction to the forming device is as follows.

[0036] See Figure 1 、 Figure 2 、 Figure 3, the forming device includes the forming die described above. In addition, the forming device further includes a first coating mechanism 2, a second coating mechanism 3, a feeding mechanism 5, and a flipping mechanism 4; the first coating mechanism 2 is arranged on one side of the forming die 1, and the first coating mechanism 2 is used to coat a lubricant on one side of the magnetic core; the flipping mechanism 4 is arranged on the side of the first coating mechanism 2 close to the forming die 1, and the flipping mechanism 4 is used to drive the magnetic core to flip so that the uncoated side of the magnetic core is exposed; the second coating mechanism 3 is arranged on the side of the flipping mechanism 4 away from the first coating mechanism 2, and the second coating mechanism 3 is used to coat a lubricant on the other side of the magnetic core; the feeding mechanism 5 is arranged on the side of the second coating mechanism 3 away from the flipping mechanism 4, and the feeding mechanism 5 is used to send the coated magnetic core to the position of the forming die 1 and take out the stamped magnetic core from the forming die 1; the forming die 1 is used to perform a stamping process on the combination of the magnetic core and the lubricant.

[0037] In some embodiments of the present invention, the first coating mechanism 2 includes a first coating bracket 21, a first transmission assembly 22, a first grasping assembly 23, and a first carrier table 24; the first coating bracket 21 is arranged on one side of the forming frame 11; the first transmission assembly 22 is arranged on the first coating bracket 21, and the first transmission assembly 22 is used to transport the magnetic core on the first coating bracket 21; the first carrier table 24 is arranged on one side of the first coating bracket 21, the first carrier table 24 has a lubricant, and the first grasping assembly 23 is used to apply the lubricant to one side of the magnetic core located on the first transmission assembly 22.

[0038] It can be understood that the first carrier table 24 has a groove, and the groove contains a lubricant for coating the magnetic core (the type of the lubricant is not specifically limited in this application). The first grasping assembly 23 has a material that can adsorb the lubricant. For example, the material can be a sponge structure, etc. When the first grasping assembly 23 moves to the first carrier table, it can adsorb the lubricant and apply the lubricant to the magnetic core.

[0039] As an example, refer to Figure 3 , the first transmission assembly 22 may include a plurality of first transmission rollers 221, a first transmission motor 222, and a first transmission belt 223; wherein, the plurality of first transmission rollers 221 are rotatably connected to the first coating bracket 21, the axial direction of the first transmission rollers 221 is the same as the length direction of the first coating bracket 21, the first transmission belt 223 is wound around the plurality of first transmission rollers 221, and the first transmission motor 222 is used to drive the first transmission rollers 221 to rotate.

[0040] As another example, the first grasping component 23 includes a grasping bracket 231, a rotating bracket 232, a lifting member 233, and an adsorbing member 234 (for adsorbing lubricant); the grasping bracket 231 is disposed on one side of the first smearing bracket 21; the rotating bracket 232 is rotatably connected to the bracket; the adsorbing member 234 is connected to the rotating bracket 232 through the lifting member 233, and the lifting member 233 is used to drive the adsorbing member 234 to move up and down to pick up the lubricant on the first carrier 24 and to smear the lubricant on the magnetic core.

Further, the adsorbing member 234 may be provided in two groups, and among them, the two groups of adsorbing members 234 are arranged oppositely along the length direction of the lifting block 2333. Thus, when one group of adsorbing members 234 adsorbs the lubricant on the first carrier 24, the other group of adsorbing members 234 (with lubricant) can smear the lubricant on the magnetic core. After smearing one side of the magnetic core is completed, the rotating bracket 232 rotates, so that the adsorbing member 234 with lubricant moves to the position of the magnetic core, and the smeared adsorbing member 234 (the lubricant has been used) moves to the position of the first carrier 24. Thus, continuous smearing of the magnetic core is achieved, which helps to improve the smearing efficiency of the lubricant on the magnetic core.

[0043] It can be understood that in this example, the adsorbing member 234 is connected to the lifting block 2333 through a translation part (not specifically marked in the drawings of the present application). Specifically, when the adsorbing member 234 on one side finishes adsorbing the lubricant on the first carrier 24, the rotating bracket 232 rotates, so that the adsorbing member 234 with lubricant moves near the first smearing bracket 21, and at this time, the plane where the adsorbing member 234 is located is higher than the plane where the first smearing bracket 21 is located. The translation part is turned on, and the translation part drives the adsorbing member 234 to move to directly above the magnetic core on the first smearing bracket 21. Under the action of the lifting member 233, the adsorbing member 234 approaches the magnetic core to perform a smearing operation on the magnetic core. It should be noted that in this example, the function of the translation part is to drive the adsorbing member 234 to perform a translation movement. This structure is well known to those skilled in the art and will not be elaborated in the present application.

[0045] It should be noted that, in the embodiment of the present invention, the falling member 251 may include a falling bracket, a falling motor, a falling screw, and a falling block (not specifically marked in this application), and the falling bracket is arranged on the first coating bracket 21; the falling screw is rotatably connected to the falling bracket, the axial direction of the falling screw is perpendicular to the plane where the first coating bracket 21 is located, the falling block is threadedly connected to the falling screw and is slidably connected to the falling bracket, and the falling motor is used to drive the falling screw to rotate. The provided uniform component 25 can uniformly process the lubricant on the magnetic core, so as to improve the coating effect of the lubricant on the magnetic core, and further improve the forming quality of the magnetic core.

[0049] It should be noted that, in the embodiment of the present invention, the first driving member 436, the second driving member 437, and the third driving member 438 can be set as a belt drive structure, and the first driving member 436, the second driving member 437, and the third driving member 438 are in the technical field well-known to those skilled in the art, and the present application will not elaborate herein.

[0050] As another example, see Figure 6 , Figure 7 , Figure 8 and Figure 9 , the clamping assembly 44 includes a first clamping wheel 441, a second clamping wheel 442, a first driving member 443, and a second driving member 444; there are multiple first clamping wheels 441, and the multiple first clamping wheels 441 are arranged along the length direction of the flipping arm 42. It should be noted that, in the embodiment of the present invention, the number of the first clamping wheels 441 is not specifically limited; there are multiple second clamping wheels 442, and the multiple second clamping wheels 442 are arranged along the length direction of the flipping arm 42. It should be noted that, in the embodiment of the present invention, the number of the second clamping wheels 442 is not specifically limited. Wherein, the first clamping wheel 441 and the second clamping wheel 442 form a clamping space for the magnetic core and the lubricant, and the size of the clamping space is variable; the first driving member 443 is configured to drive the first clamping wheel 441 to rotate; the second driving member 444 is configured to drive the second clamping wheel 442 to approach the first clamping wheel 441.

[0051] It can be understood that when the magnetic core coated with lubricant on one side moves on the first coating bracket 21, when the magnetic core is about to move to the blanking end, at this time, the flipping arm 42 has flipped to the position of the blanking end, the clamping space and the movement track of the magnetic core are on the same horizontal line. Under the action of inertia, part of the magnetic core moves into the clamping space. At this time, the magnetic core that moves into the clamping space is not enough to complete the flipping operation. In this case, the first driving member 443 is turned on, and the first driving member 443 drives the first clamping wheel 441 to move. In this way, the magnetic core can move in the clamping space. When the magnetic core moves to a suitable position (a position convenient for flipping), the second clamping wheel 442 approaches the first clamping wheel 441. At this time, the magnetic core is clamped, and the subsequent flipping process can be realized.

[0052] As an example, refer to Figure 8 、 Figure 9 , the first driving member 443 includes a driving motor 4431, a driving belt 4432 and a driving wheel 4433. There are multiple driving wheels 4433, and the driving wheels 4433 are rotatably connected to the flipping arm 42, and the multiple driving wheels 4433 are correspondingly connected to the first clamping wheel 441; the driving belt 4432 is used to connect adjacent driving wheels 4433; the driving motor 4431 is used to drive any driving wheel 4433 to rotate.

[0053] As another example, refer to Figure 8 、 Figure 9 , the second driving member 444 includes a first electromagnet 4441, a second electromagnet 4442 and a return spring 4443; multiple second clamping wheels 442 are slidably connected to the flipping arm 42, and the second clamping wheels 442 can be rotatably connected to the flipping arm 42.

[0054] It can be understood that there is a slidable connection block 4444 on the flipping arm 42, and the second clamping wheel 442 is rotatably connected to the connection block 4444. There are multiple first electromagnets 4441, and the multiple first electromagnets 4441 are connected to the second clamping wheel 442; the second electromagnet 4442 is arranged on the flipping arm 42 through the return spring 4443; the return spring 4443 is used to drive the second electromagnet 4442 to return to its original position.

[0055] Specifically, electricity can be supplied to the first electromagnet 4441 and the second electromagnet 4442. When the sides of the first electromagnet 4441 and the second electromagnet 4442 close to each other are of opposite polarities, the first electromagnet 4441 and the second electromagnet 4442 move away from each other. At this time, the first electromagnet 4441 drives the second clamping wheel 442 away from the first electromagnet 4441, and the second clamping wheel 442 approaches the first clamping wheel 441. In this way, the clamping of the magnetic core can be realized.

[0056] In addition, in some embodiments, refer to Figure 5, a limiting post 412 can also be provided on the inner side of the flipping bracket 41. Correspondingly, a limiting groove 413 corresponding to the limiting post 412 can be provided on the flipping arm 42. The provided limiting post 412 can further limit the movement track of the flipping arm 42, improving the flipping stability of the magnetic core.

[0057] In some embodiments of the present invention, referring to Figure 1 , the second coating mechanism 3 includes a second coating bracket 31, a second transmission component 32, a second grasping component 33, and a second carrier 34; the second coating bracket 31 is arranged on the side of the flipping bracket 41 away from the first coating bracket 21; the second transmission component 32 is arranged on the second coating bracket 31 and is used for transporting the magnetic cores on the second coating bracket 31; the second carrier 34 is arranged on one side of the second coating bracket 31, and the second carrier 34 has lubricant; the second grasping component 33 is used for applying the lubricant to one side of the magnetic core located on the second transmission component 32. It should be noted that in the embodiments of the present invention, the specific structure of the first coating mechanism 2 is the same as that of the second coating mechanism 3, and the specific structure of the second coating mechanism 3 will not be elaborated in this application.

[0058] In some embodiments of the present invention, referring to Figure 1 , Figure 10 , the feeding mechanism 5 includes a feeding turntable 51, a transporting component 52, and a taking component 53; the feeding turntable 51 is rotatably connected between the second coating mechanism 3 and the forming frame 11; there are multiple transporting components 52 and taking components 53, wherein the multiple transporting components 52 and the multiple taking components 53 are distributed at intervals on the feeding turntable 51; the transporting component 52 is used for sending the magnetic cores on the second coating mechanism 3 into the stamping space; the taking component 53 is used for taking out the stamped magnetic cores from the stamping space.

It should be noted that the pushing member in this example has the same structure as the clamping component 44 on the flipping layout, and the present invention will not elaborate on this here.

[0060] Specifically, when the magnetic core moves to the end of the second coating bracket 31 of the second coating mechanism 3, due to a certain inertia, the magnetic core will move into the transportation space formed by the first clamping arm and the second clamping arm. The magnetic core is transported, the feeding turntable 51 rotates, and the feeding turntable 51 drives the transportation component 52 to move to the extrusion mechanism. The pushing member pushes the magnetic core into the extrusion space to perform an extrusion operation on the magnetic core.

[0061] As another example, the picking component 53 includes a picking bracket, a picking motor, a picking screw, a picking block, and a feeding member (not specifically marked in this application); the picking bracket is arranged on the feeding turntable 51 and is located on one side of the transportation bracket.
