Description

Technical Field

[0001] This utility model relates to the field of manufacturing equipment technology, specifically to a punching and cutting manufacturing device for motor core laminations. Background Technology

[0002] The motor core lamination punching and manufacturing equipment is mainly used to produce motor core laminations efficiently and accurately. It is one of the core equipment in motor manufacturing. It punches silicon steel sheets into specific shapes according to design requirements to form the basic unit of the motor core.

[0003] The existing technology has the following problems:

[0004] The existing equipment cannot limit and fix the silicon steel sheet during use. If the silicon steel sheet is displaced or shakes during the punching process, the key parameters such as the hole diameter and outer dimensions of the punch will deviate from the design requirements, affecting the assembly accuracy and performance of the motor core. In addition, the existing equipment cannot clean out the debris inside the mold. The debris left in the mold will occupy the cavity space, causing the silicon steel sheet to be misaligned during punching, resulting in problems such as punch size deviation and hole misalignment. Furthermore, the debris may embed into the surface of the punch, forming scratches or dents, damaging the surface of the silicon steel sheet. Utility Model Content

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1 As shown, this utility model provides a punching and manufacturing device for motor core laminations, including a base 1, a support plate 2 fixedly connected to the upper side of the base 1, a top seat 3 fixedly connected to the upper side of the support plate 2, a cylinder 4 fixedly connected to the lower side of the top seat 3, a punching block 5 fixedly connected to the output end of the cylinder 4, a mold 7 fixedly connected to the upper side of the base 1, a fixing ring 8 fixedly connected to the upper side of the base 1, and two fixing blocks 6 fixedly connected to the upper side of the base 1. When a silicon steel sheet is placed above the fixing ring 8 on the base 1, the cylinder 4 is started, and its output end pushes the punching block 5 downward. The punching block 5 cooperates with the mold 7 to punch the silicon steel sheet, completing the basic punching and forming of the core lamination. The two fixing blocks 6 are used to support the relevant components for limiting and fixing the silicon steel sheet, ensuring the stability of the silicon steel sheet during the punching process.

[0024] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, a motor 9 is fixedly connected to the upper side of the inner surface of the mold 7, a turntable 10 is fixedly connected to the output shaft of the motor 9, a plurality of inclined blocks 11 are fixedly connected to the upper side of the turntable 10, a plurality of grooves 12 are provided on the upper side of the mold 7, a push block 13 is slidably connected to the inner surface of the groove 12, a guide post 14 is movably connected to the inclined surface of the inclined block 11, a plurality of fixing brackets 15 are fixedly connected to the inner surface of the mold 7, the outer wall of the guide post 14 is slidably connected to the fixing bracket 15, a spring 16 is sleeved on the outer wall of the guide post 14, the upper end of the guide post 14 is fixedly connected to the push block 13, and one end of the spring 16 is... The spring 16 is fixedly connected to the fixed frame 15, and the other end of the spring 16 is fixedly connected to the push block 13. When it is necessary to clean the debris in the mold 7, the motor 9 is started. The output shaft of the motor 9 drives the turntable 10 to rotate. Multiple inclined blocks 11 on the turntable 10 rotate together with it. The inclined surface of the inclined block 11 contacts the guide post 14 and pushes the guide post 14 to slide upward in the fixed frame 15. The guide post 14 drives the push block 13 to move upward in the groove 12. The push block 13 pushes the debris in the mold 7 upward. When the inclined block 11 rotates to the point where it no longer contacts the guide post 14, the elastic force of the spring 16 resets the guide post 14 and the push block 13 for the next cleaning operation.

[0025] like Figure 4-5 As shown, this utility model provides a technical solution: Preferably, each of the two fixed blocks 6 has a sliding groove 17 on its opposite surface. A limit post 18 is fixedly connected to the inner surface of the sliding groove 17. A knob 20 is rotatably connected to each of the two fixed blocks 6 on their opposite sides. A worm gear 21 is fixedly connected to the left side of the knob 20. A worm wheel 22 is meshed with the outer wall of the worm gear 21. A rotating shaft 23 is fixedly connected through the front side of the worm wheel 22. A gear 24 is fixedly connected to the outer wall of the rotating shaft 23. A rack 26 is meshed with the outer wall of the gear 24. A connecting plate 25 is slidably connected to the outer wall of the limit post 18. The right side of the connecting plate 25 is fixedly connected to the rack 26. A clamping plate 19 is fixedly connected to the outer wall of plate 25. Rotating knob 20 causes worm 21 to rotate, and worm 21 meshes with worm wheel 22, thereby causing worm wheel 22 and rotating shaft 23 to rotate. Gear 24 on rotating shaft 23 rotates accordingly, and gear 24 meshes with rack 26, driving rack 26 to move. Rack 26 drives connecting plate 25 to slide along limiting post 18 in slide groove 17. Clamping plate 19 on connecting plate 25 then approaches silicon steel sheet until the silicon steel sheet is clamped and fixed, thereby limiting the silicon steel sheet and preventing it from shifting or shaking during punching. Rotating knob 20 in the opposite direction can release clamping plate 19 from silicon steel sheet.

[0026] The working principle of the motor core lamination punching and manufacturing device will be explained in detail below.

[0027] like Figure 1-5As shown, the silicon steel sheet is placed above the fixing ring 8 on the base 1. The cylinder 4 is started, and its output end pushes the stamping block 5 downward. The stamping block 5 cooperates with the mold 7 to perform a punching operation on the silicon steel sheet, completing the basic punching and forming of the iron core lamination. The two fixing blocks 6 are used to support the relevant components for limiting and fixing the silicon steel sheet, ensuring the stability of the silicon steel sheet during the punching process. When it is necessary to clean the debris in the mold 7, the motor 9 is started. The output shaft of the motor 9 drives the turntable 10 to rotate. The multiple inclined blocks 11 on the turntable 10 rotate together with it. The inclined surface of the inclined block 11 contacts the guide post 14 and pushes the guide post 14 to slide upward in the fixing frame 15. The guide post 14 drives the push block 13 to move upward in the groove 12. The push block 13 pushes the debris in the mold 7 towards the groove 12. When the inclined block 11 rotates to a position where it no longer contacts the guide post 14, the elastic force of the spring 16 resets the guide post 14 and the push block 13 for the next cleaning operation. Rotating the knob 20 causes the worm gear 21 to rotate, and the worm gear 21 meshes with the worm wheel 22, thereby causing the worm wheel 22 and the rotating shaft 23 to rotate. The gear 24 on the rotating shaft 23 rotates accordingly, and the gear 24 meshes with the rack 26, driving the rack 26 to move. The rack 26 drives the connecting plate 25 to slide along the limiting post 18 in the slide groove 17. The clamping plate 19 on the connecting plate 25 then approaches the silicon steel sheet until it is clamped and fixed, thus limiting the silicon steel sheet and preventing it from shifting or shaking during the punching process. Rotating the knob 20 in the opposite direction allows the clamping plate 19 to release the silicon steel sheet.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
