Description

A silicon steel sheet cutting and stacking device for transformer core processing Technical Field

[0001] This utility model relates to the field of transformer core processing technology, and in particular to a silicon steel sheet cutting and stacking device for transformer core processing. Background Technology

[0002] Silicon steel sheet cutting and stacking devices are mainly used to cut silicon steel sheets according to design requirements and then stack them into iron cores. For example, a silicon steel sheet cutting and stacking device for transformer iron core processing disclosed in existing technical solution (CN220553358U) includes a frame and a cutting platform mounted on the frame. A cutting mechanism is mounted on the frame above the cutting platform, and a stacking platform is mounted on the frame in front of the cutting platform. An inclined transition plate is mounted on the cutting platform near one end of the stacking platform. A lifting baffle is mounted at one end of the stacking platform, and a pushing plate is mounted at the other end of the stacking platform. A vertically downward hydraulic cylinder is mounted on the frame above the stacking platform between the pushing plate and the lifting baffle. A pressure plate is mounted on the telescopic end of the hydraulic cylinder. This device achieves stacking during the cutting and forward pushing of silicon steel sheets, resulting in a high degree of automation and improved processing efficiency.

[0003] Currently, when silicon steel sheet cutting and stacking equipment cuts silicon steel sheets, blade wear may cause burrs, tears, or even tiny fragments to appear on the edges of the silicon steel sheets.

[0004] If the waste generated during the cutting and stacking of silicon steel sheets in the transformer core processing is not cleaned up in time, the waste will accumulate on the worktable of the silicon steel sheet cutting and stacking device. This will not only affect the cutting of silicon steel sheets, but if the waste is mixed between the silicon steel sheets and directly stacked together, it will reduce the quality of the transformer core.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please refer to Figures 1 to 3. A silicon steel sheet cutting and stacking device for processing transformer cores includes a processing device body 1. A positioning plate 2 is slidably installed on the top of the processing device body 1, and a cutting component 3 for cutting silicon steel sheets is provided on one side of the positioning plate 2. A conveying plate 9 is provided on one side of the cutting component 3, and a guide plate 6 is slidably installed on the top of the conveying plate 9. A waste collection component 4 for collecting waste is provided on the cutting component 3. A discharge plate 8 is movably connected to the right side of the processing device body 1, and a pressing cylinder 7 is fixed above the processing device body 1.

[0027] It is important to note that the discharge plate 8 is vertically slidably installed on the right side of the main body 1 of the processing device. When the discharge plate 8 moves upward, the stacked silicon steel sheets can move outward from the discharge plate 8. The driving method can be a cylinder or a motor drive, etc. The telescopic end of the pressing cylinder 7 can be fixedly connected to the pressing plate to apply pressure to the silicon steel sheets. In order to facilitate the stacking of silicon steel sheets, a pushing mechanism can also be set on the left side of the discharge plate 8. The pushing mechanism includes a pushing cylinder and a pushing plate, which pushes the silicon steel sheets to move closer to the discharge plate 8 to facilitate the alignment of the silicon steel sheets. The above are all existing technologies. For detailed principles, please refer to the existing public technical solution (CN220553358U), which will not be elaborated here.

[0028] The waste collection assembly 4 includes a collection bin 401. A vacuum pump 402 is fixedly connected to one side of the collection bin 401 via a pipe. A vacuum pipe 403 is fixedly connected to the other side of the collection bin 401. A vacuum plate 404 is fixedly connected to the end of the vacuum pipe 403. A vacuum groove is provided at the bottom of the vacuum plate 404.

[0029] By adopting the above technical solution, after the silicon steel sheet is cut by the cutting component 3, the dust pump 402 can be started. The dust pump 402 sucks the waste generated during the cutting process into the dust suction plate 404 with a cavity through the dust suction groove at the bottom of the dust suction pipe 403, and then into the interior of the dust suction pipe 403 through the dust suction plate 404, and then into the collection chamber 401 for collection. The size of the dust suction groove is much smaller than the size of the silicon steel sheet, so the silicon steel sheet will not be sucked into the dust suction groove. With the waste collection component 4, the waste generated can be collected into the collection chamber 401 under the action of the dust pump 402, thereby avoiding the waste from existing on the top of the processing device body 1 and affecting the subsequent cutting of the silicon steel sheet.

[0030] Specifically, as shown in Figures 2 and 4, the cutting assembly 3 includes a cutting bracket 301 fixed to the top of the processing device body 1, and a cutting cylinder 302 fixed to the top of the cutting bracket 301. The telescopic end of the cutting cylinder 302 passes through the cutting bracket 301 and is fixed to a support frame 304. A cutting blade 303 is detachably connected to the bottom of the support frame 304. A guide groove 311 is provided at the connection between the support frame 304 and the cutting bracket 301, and a guide slider 3 fixedly connected to the support frame 304 is slidably connected inside the guide groove 311. 10. The dust collection plate 404 is fixed to the bottom of the support frame 304 and located on the left and right sides of the cutter 303. The cutter 303 has multiple mounting holes 305 inside. The support frame 304 has multiple insertion holes 306 corresponding to the mounting holes 305 inside. The insertion holes 306 are fitted with mounting rods 309 inside. The end of the mounting rod 309 is fixed with a pull plate 307. A connecting spring 308 is fixedly connected between the pull plate 307 and the support frame 304. The connecting spring 308 is sleeved on the surface of the mounting rod 309.

[0031] A drive assembly 5 is installed at the bottom of the guide plate 6 and the positioning plate 2. The drive assembly 5 includes a bidirectional lead screw 502 installed at the bottom of the guide plate 6 and the positioning plate 2 through a lead screw sleeve. One end of the bidirectional lead screw 502 is fixedly connected to a transmission worm gear 503. The drive assembly 5 also includes a servo motor 501 fixed inside the main body 1 of the processing device. The power output end of the servo motor 501 is fixedly connected to an output shaft 505. A transmission worm 504 is provided at the connection between the transmission worm gear 503 and the output shaft 505.

[0032] By adopting the above technical solution, the cutting cylinder 302 is activated, which pushes the support frame 304 downward. The guide slider 310 on the support frame 304 slides inside the guide groove 311 to guide it. The cutting blade 303 on the support frame 304 can cut the silicon steel sheet. The cut silicon steel sheet slides down the discharge plate 8 to the bottom of the pressing cylinder 7. During this process, the position of the guide plate 6 and the positioning plate 2 can be adjusted by the drive component 5. The servo motor 501 can drive the output shaft 505 to rotate, and the output shaft 505 drives the transmission worm gear 504 fixedly connected to it to drive the transmission worm wheel 503 to rotate. At this time, the transmission worm wheel 503 can drive the bidirectional lead screw 502 to rotate. When the two sets of bidirectional lead screws 502 rotate, under the action of the screw sleeve, they can drive the two sets of guide plates 6 and positioning plates 2 to slide in opposite directions, so that the distance between the two sets of guide plates 6 and the two sets of positioning plates 2 is adapted to the width between the silicon steel sheets.

[0033] Working principle: Activating the cutting cylinder 302 pushes the support frame 304 downwards, allowing the cutting blade 303 on the support frame 304 to cut the silicon steel sheet. The cut silicon steel sheet slides down the discharge plate 8 to below the pressing cylinder 7. After the silicon steel sheet is cut by the cutting assembly 3, the dust pump 402 can be activated. The dust pump 402 draws the waste generated during cutting into the vacuum plate 404 with a cavity through the vacuum groove at the bottom of the vacuum pipe 403, and then into the interior of the vacuum pipe 403 via the vacuum plate 404, subsequently entering... The collection chamber 401 collects the silicon steel sheets. The size of the dust collection trough is much smaller than the size of the silicon steel sheets, so the silicon steel sheets will not be sucked in by the dust collection trough. When the cutting blade 303 needs to be replaced, pull the pull plate 307. The pull plate 307 can drive the mounting rod 309 to disengage from the mounting hole 305 and the insertion hole 306. The connecting spring 308 is stretched, and the new cutting blade 303 is locked inside the support frame 304. When the pull plate 307 is released, under the action of the connecting spring 308, the mounting rod 309 is reinserted into the mounting hole 305 and the insertion hole 306, and the cutting blade 303 can be replaced.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
