Description

Technical Field

[0001] The present application relates to the technical field of vacuum pumping mechanisms, and in particular to a vacuum pumping mechanism for a self-adhesive motor core stamping die. Background Art

[0002] With the rapid development of fields such as electric vehicles, household appliances, and electronic devices, higher requirements are put forward for the magnetic properties, energy conservation and environmental protection characteristics, and manufacturing precision of motor cores. As a core component, the manufacturing process of ultra-thin self-adhesive motor cores involves multiple links such as die design, processing, and debugging, and the precision and stability of the die directly determine the product quality of the core.

[0003] Regarding the above related technologies, the inventor believes that during the stamping process of the existing self-adhesive motor core, air often remains in the die, resulting in poor adhesion between the core and the die during stamping, affecting the stamping precision and the final quality of the core. Moreover, during the stamping process of the motor core, if the dust and impurities on the die surface are not cleaned in time, it will not only pollute the stamping environment, affect the product quality, but also accelerate the wear of the die and shorten its service life. Summary of the Utility Model

[0014] Optionally, the outer surfaces of the plurality of self-adhesive iron cores and the three pressing plates are respectively slidably fitted with the inner surfaces of the three extrusion grooves.

[0015] By adopting the above technical solution, the self-adhesive iron core can be closely attached to the mold during the air extraction process, and at the same time, the pressing plate can effectively apply pressure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 3 , and make a further detailed description of the present application.

[0030] Embodiment

[0031] A vacuum pumping mechanism for a self - adhesive motor iron core stamping mold, referring toFigure 1 and Figure 2 , above the vacuum mold 4 fixed on the bottom plate 1, three cylinders 21 are tightly connected to the air extraction pipe 22 through their output ends. The air extraction pipe 22 is accurately aligned and inserted into three air extraction slots 23 at the upper end of the vacuum mold 4. The lower inner wall of the air extraction slot 23 is provided with air ventilation slots 24, and these air ventilation slots 24 communicate with three extrusion slots 201 on one side of the mold. An air ventilation plate 25 is fixed on the inner surface of the extrusion slot 201. A plurality of air ventilation holes 26 are opened on the air ventilation plate 25 to achieve air flow transmission. A limiting rod 27 is fixed on one side of the air ventilation plate 25. The self-adhesive iron core 28 and the extrusion plate 29 can both slide along the limiting rod 27 to ensure the stability and position accuracy of the iron core during the stamping process.

[0032] Refer to Figure 2 , the annular distribution of the air ventilation holes 26 ensures that the air ventilation plate 25 can evenly and efficiently transmit air flow in the extrusion slot 201, further enhancing the effect of vacuum pumping. The design of the mounting frame 20 enhances the connection stability between the cylinder 21 and the vacuum mold 4. The self-adhesive iron core 28 can closely adhere to the inside of the mold during the air extraction process, and at the same time, the extrusion plate 29 can effectively apply pressure.

[0033] Refer to Figure 3 , the air knife 30 is connected to an external air source through the connection port 5 at its upper end. Springs 38 are respectively provided on the rotating plates 31 fixedly installed on both sides of the air knife 30. The other ends of the springs 38 are connected to the positioning plates 37. On two support plates 34 installed on one side of the vacuum mold 4, a rotating clamping plate 33 is fixed. The rotating slot 32 of the rotating clamping plate 33 cooperates with the spring 38 to allow the rotating plate 31 to rotate within a specific range. At the same time, tooth teeth 36 are fixed on one side of both the rotating plate 31 and the rotating clamping plate 33. These tooth teeth 36 engage with each other during the rotation process, enhancing the connection stability between the air knife 30 and the vacuum mold 4 and ensuring the stability and accuracy during the dust removal operation.

[0034] Refer to Figure 3 , the storage box 6 can collect the impurities and dust blown off by the air knife 30 and can be fixed or disassembled through the clamping groove 7. The distribution method of the tooth teeth 36 enhances the biting force and stability between the rotating plate 31 and the rotating clamping plate 33. The design of the positioning groove 35 enables the positioning plate 37 to perform limited rotation within the positioning groove 35.

[0035] The implementation principle of the embodiment of this application is as follows: Through the air extraction mechanism 2, the self-adhesive iron core 28 is placed into the extrusion groove 201 and sleeved on the limiting rod 27, and then sealed by the extrusion plate 29. After that, the air cylinder 21 on the mounting frame 20 is started, so that the air cylinder 21 can drive the air extraction pipe 22 to move in the air extraction groove 23 through the output end. As a result, the air in the extrusion groove 201 can enter the air ventilation groove 24 and the air extraction groove 23 through the ventilation holes 26 on the ventilation plate 25. Thus, when the air inside the vacuum mold 4 moves, it can drive the extrusion plate 29 to extrude the self-adhesive iron core 28.

[0036] The annular distribution of the ventilation holes 26 ensures that the ventilation plate 25 can transfer air evenly and efficiently in the extrusion groove 201, further enhancing the effect of vacuum pumping. The design of the mounting frame 20 enhances the connection stability between the air cylinder 21 and the vacuum mold 4. The self-adhesive iron core 28 can fit tightly in the mold during the air extraction process, and at the same time, the extrusion plate 29 can effectively apply pressure.

[0037] Through the dust removal mechanism 3, the air knife 30 is rotated, so that the teeth 36 on one side of the rotating plate 31 driven by the air knife 30 can slide on the teeth 36 on one side of the rotating clamping plate 33 and engage when sliding to a certain angle. At the same time, the rotating plate 31 will pull the spring 38 during rotation. The spring 38 can be limited on the support plate 34 through the positioning plate 37. After engaging when sliding to a certain angle, the spring 38 can tighten the rotating plate 31 and the rotating clamping plate 33 to make their engagement firm.

[0038] The storage box 6 can collect the impurity dust blown off by the air knife 30 and can be fixed or disassembled through the clamping groove 7. The distribution method of the teeth 36 enhances the biting force and stability between the rotating plate 31 and the rotating clamping plate 33. The design of the positioning groove 35 enables the positioning plate 37 to rotate and be limited in the positioning groove 35.

[0039] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
