Abstract
Description
Technical Field
[0001] This application relates to the field of motor manufacturing technology, specifically to a rotor core manufacturing apparatus for an external rotor motor. Background Technology
[0002] In the field of motor manufacturing, the stamping of rotor cores is a crucial process. To accomplish this task efficiently and accurately, stamping machines specifically designed for rotor core stamping have emerged.
[0003] According to Chinese Publication No. CN216502042U, a stamping machine for producing rotor cores includes a bottom housing and a light receiving plate, which is fixedly mounted on the upper part of the bottom housing. The beneficial effect of this invention is that the inclusion of an infrared sensor structure provides excellent infrared sensing protection. The outer fixing plate of the infrared sensor is fixedly connected to the movable stamping plate via an inlaid insert plate, ensuring effective installation and preventing it from easily falling off during use. When in use, the operator turns on the switch at the top of the infrared lamp body, which emits light. The light is focused by the spotlight housing, making the infrared light emission clearer and easier for the light receiving plate to receive. If the light is received, power is supplied for stamping; otherwise, no power is supplied, effectively ensuring operator safety. The inclusion of a spring-loaded limit post structure facilitates limiting and buffering operation.
[0004] During the stamping process, the sheet metal moves and multiple sets of rotor laminations are stamped at multiple points on the sheet metal. At this time, the scrap on the sheet metal that has been stamped with rotor laminations is still connected to the unstamped parts of the sheet metal. The scrap on the sheet metal located outside the stamping equipment will bend due to the influence of gravity, which will cause the sheet metal on the stamping equipment to bend. This will cause the stamping process to be offset, resulting in scrap. Utility Model Content
[0005] The purpose of this application is to provide a rotor core manufacturing apparatus for an external rotor motor, in order to solve the problem mentioned in the background art that the sheet metal scrap located outside the stamping equipment will bend due to the influence of gravity, causing the sheet metal on the stamping equipment to bend, which will lead to the stamping process being offset and resulting in scrap.
[0006] To achieve the above objectives, this application provides the following technical solution: a rotor core manufacturing device for an external rotor motor, comprising: a workbench, a large cylinder, a stamping block, a dividing and pushing assembly, and a collection box. The main body of the manufacturing device consists of a workbench, a large cylinder disposed above the workbench, and a stamping block disposed at the bottom output end of the large cylinder.

The collection box is disposed on the outer wall of the workbench.
[0007] By adopting the above technical solution, it is possible to stably cut the waste material of the board and collect the cut waste material by rotating it.
[0008] Preferably, the dividing and pushing assembly further includes an anti-slip pad adhered to the outer wall of the positioning block, the anti-slip pad being made of rubber.

[0010] Preferably, the dividing and pushing assembly further includes a base fixed above the outer wall of the stamping block, and a rotating shaft is welded to the top of the base, with a first block rotatably connected to the rotating shaft of the base.
[0011] By adopting the above technical solution, the No. 1 block can change its angle on the base through the rotating shaft.
[0012] Preferably, the segmentation and pushing assembly further includes a second block whose bottom is welded to the top of the fixed block, and the top of the second block has an integrally formed rotating shaft.
[0013] By adopting the above technical solution, the second block can provide the external third block with a stable angle change through the rotating shaft.
[0014] Preferably, the segmentation pushing assembly further includes a third block that is rotatably connected to the shaft of the second block.
[0015] By adopting the above technical solution, the No. 3 block can simultaneously change the position of the external small cylinder while changing its angle.
[0016] Preferably, the segmentation and pushing assembly further includes small cylinders with their two ends fixed to the outer walls of block one and block three, respectively.
[0017] By adopting the above technical solution, the small cylinder can change its angle by pushing the third block at the output end.
[0018] In summary, this application has the following beneficial effects: by setting up a dividing and pushing component, the waste board material outside the workbench can be automatically cut, which can prevent the board material outside the workbench from bending due to gravity. When the waste board material is cut and accumulates on the workbench, the positioning block of the dividing and pushing component can stabilize the cutting process and, through its rotation and the push of the spring, drive the waste material to automatically move into the collection box for storage, thereby improving the efficiency of waste material cutting and collection.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] The following is in conjunction with the appendix Figure 1-3 The embodiments of this application will be described in further detail.
[0025] Please see Figures 1-3 This embodiment provides a technical solution: a rotor core manufacturing device for an external rotor motor, comprising: a workbench 1, a large cylinder 2, a stamping block 3, a dividing and pushing assembly 4, and a collection box 5;
[0026] The main body of the manufacturing device consists of a workbench 1, a large cylinder 2 set above the workbench 1, and a stamping block 3 set at the bottom output end of the large cylinder 2. The above is the prior art and will not be described in detail below.
[0027] The dividing and pushing assembly 4 is disposed on the outer wall of the stamping block 3 and is used for cutting the waste material and pushing the cut waste material to move. The dividing and pushing assembly 4 includes a mounting block 401 fixed on the outer wall of the stamping block 3, a cutting blade 402 disposed at the bottom of the mounting block 401, a connecting shaft 403 welded to the outer wall of the mounting block 401, a fixing block 404 rotatably connected to the connecting shaft 403, a guide rod 405 vertically slidably connected inside the fixing block 404, a positioning block 406 welded to the bottom end of the guide rod 405, and a spring 408 sleeved on the guide rod 405.
[0028] The segmentation push assembly 4 also includes an anti-slip pad 407 bonded to the outer wall of the positioning block 406. The anti-slip pad 407 is made of rubber. A base 409 is fixed above the outer wall of the stamping block 3. A rotating shaft is welded to the top of the base 409. A first block 410 is rotatably connected to the rotating shaft of the base 409. A second block 411 is welded to the top of the fixed block 404. A rotating shaft is integrally formed on the top of the second block 411. A third block 412 is rotatably connected to the rotating shaft of the second block 411. Small cylinders 413 are fixed to the outer walls of the first block 410 and the third block 412 at both ends.
[0029] The collection box 5 is set on the outer wall of the workbench 1.
[0030] The implementation principle of the rotor core manufacturing apparatus for an external rotor motor according to this application is as follows:
[0031] First, the sheet metal is placed on the workbench 1. By starting the large cylinder 2, the large cylinder 2 can drive the stamping block 3 on the bottom output end to move vertically downward. When the stamping block 3 applies pressure to the sheet metal placed below, the sheet metal can be stamped to form the required rotor laminations. Then, by moving the sheet metal horizontally, the unstamped area of the sheet metal is moved to the bottom of the stamping block 3 to perform the work of stamping rotor laminations again.
[0032] Secondly, when the waste material of the sheet moves out of the stamping area of the workbench 1, the large cylinder 2 drives the stamping block 3 to stamp the unprocessed area of the sheet. At this time, the mounting block 401 is connected to the stamping block 3, so that the bottom-connected cutting blade 402 applies pressure to the sheet together, thereby separating the waste material after processing from the unprocessed area. When the cutting blade 402 cuts, the positioning block 406 at the bottom of the fixed block 404 can be squeezed by the spring 408, so that the positioning block 406 can move stably in the vertical direction inside the fixed block 404 through the guide rod 405. Because the bottom of the positioning block 406 is provided with an anti-slip pad 407, the anti-slip pad 407 is in close contact with the sheet, which ensures the stability of the cutting blade 402 when cutting.
[0033] Finally, after the cutting blade 402 completes the cutting of the board, the small cylinder 413 is activated. The two ends of the small cylinder 413 are respectively set on the first block 410 and the third block 412. Since the first block 410 and the third block 412 are rotated on the second block 411 of the base 409 and the fixed block 404 respectively through the rotating shaft, the small cylinder 413 can drive the fixed block 404 to change its angle on the mounting block 401 through the connecting shaft 403 during the displacement of the third block 412 at the output end. Because the positioning block 406 at the bottom of the fixed block 404 can always be in contact with the board waste on the worktable 1 through the compression of the spring 408, the board waste can be pushed to move into the collection box 5 for collection after the angle is changed.
[0034] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
