Description

Technical Field

[0001] The utility model relates to the technical field of iron core stamping, in particular to a stamping device for producing motor rotor iron cores. Background Technique

[0002] Motor rotor punching sheets are usually laminated from silicon steel sheets with a thickness of 0.5 mm, and then fixed on the rotor bracket or the rotating shaft. They are widely used, such as in stepper motors, AC / DC motors, reduction motors, outer rotor motors, shaded pole motors, synchronous and asynchronous motors, etc. For finished motors, the punching sheets play a crucial role among motor accessories.

[0003] For the waste generated during the stamping process by traditional stamping devices, traditional devices often lack effective collection and treatment methods, which is not conducive to environmental protection and resource recycling. Also, during the stamping process, the stamping head and the iron core raw material are exposed to the external environment. If debris is generated, it is easy to cause harm to the staff, and the iron core is prone to shaking during the instant of stamping, affecting the stamping effect. In view of the above situation, we have introduced a stamping device for producing motor rotor iron cores. Content of the Utility Model

[0004] The purpose of the utility model is to provide a stamping device for producing motor rotor iron cores to solve the problems of inconvenient waste collection and lack of protection during stamping mentioned in the above background technique.

[0005] The technical solution of the utility model is as follows:

[0006] A workbench, the rear side wall of the workbench is fixedly connected with a support frame, the upper end inside the support frame is fixedly connected with a first hydraulic rod, the telescopic end of the first hydraulic rod is fixedly connected with a stamping head, the upper end surface of the stamping head is fixedly connected with a fixed frame, the lower end surface of the front end of the fixed frame is connected with a spring, the end of the spring is connected with a protective shell, a telescopic sleeve rod is arranged inside the spring, and both ends of the telescopic sleeve rod are fixedly connected with the upper end surface of the protective shell and the lower end surface of the front end of the fixed frame respectively, and the lower end of the protective shell is fixedly connected with a rubber ring;

[0007] On the right side wall of the telescopic end of the first hydraulic rod, there is a fixedly connected connecting rod, the end of the connecting rod is fixedly connected with a connecting frame, a tool rest is connected inside the lower end of the connecting frame, a blade is fixedly connected to the lower end surface of the tool rest, threaded bolts are rotatably connected inside both sides of the tool rest, the front end wall of the workbench is fixedly connected with a fixing plate, the upper end inside the fixing plate is fixedly connected with a third hydraulic rod, and the telescopic end of the third hydraulic rod is connected with a limiting plate.

[0008] Furthermore, air holes are arranged at the edge of the upper end surface of the stamping head.

[0009] By opening an air hole inside the stamping head, after stamping, the rotor core fits tightly with the stamping head. An air pipe is externally connected through the opened air hole. Each time blanking is carried out, air is injected into the air pipe to blow the core down for material taking. Automated material taking reduces the need for manual intervention, thereby improving the efficiency of the entire production line.

[0010] Furthermore, a cross plate is fixedly connected to the inner wall of the limiting plate. A threaded rod is connected inside the cross plate. The end of the threaded rod is rotatably connected to a pressing plate, and a limiting roller shaft is arranged on the lower end surface of the pressing plate.

[0011] When the limiting plate moves to a suitable position, rotate the threaded rod to make the pressing plate slide downward along the inner wall of the limiting plate, so that the limiting roller shaft rotatably connected to the lower end surface of the pressing plate contacts the core raw material evenly, realizing the stability during stamping and avoiding the bouncing of the raw material.

[0012] The present utility model provides a stamping device for the production of motor rotor cores through improvement. Compared with the prior art, it has the following improvements and advantages:

[0013] Firstly: In the present utility model, through the downward extrusion of the rubber ring at the lower end of the protective shell, the fixation of the core raw material is realized. At this time, the stamping head continues to move downward to complete the stamping work. The protective shell is slidably connected to the stamping head. The protective shell is compressed on the fixed frame through a spring and a telescopic sleeve rod to realize the protection and fixation during stamping, effectively preventing the splashing and scattering of raw materials during stamping, reducing the operation risk. At the same time, the design of fixing the core raw material with the rubber ring also enhances the stability of the core raw material during stamping, improving the stamping accuracy and product quality.

[0014] Secondly: In the present utility model, by driving the blade downward, the waste material after stamping is cut and sent into the waste material box. Through automatic cutting of the waste material, the need for manual intervention is reduced, thereby accelerating the production speed. At the same time, the waste material is timely sent into the waste material box, avoiding the accumulation and interference of the waste material, ensuring the continuity of the stamping process, reducing the clutter in the working area, making the working environment cleaner. And when manually pushing the core raw material on the upper surface of the workbench, the limiting plate expands and contracts through the third hydraulic rod to adjust the distance between the limiting plates on both sides, ensuring the stability during feeding and avoiding deviation during stamping.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] The present utility model provides a stamping device for the production of motor rotor cores by improvement. As Figures 1 - 3 shown, it includes a workbench 1. The rear side wall of the workbench 1 is fixedly connected with a support frame 2. The upper end inside the support frame 2 is fixedly connected with a first hydraulic rod 201. The telescopic end of the first hydraulic rod 201 is fixedly connected with a punching head 202. The upper end surface of the punching head 202 is fixedly connected with a fixing frame 3. The lower end surface of the front end of the fixing frame 3 is connected with a spring 301. The end of the spring 301 is connected with a protective housing 303. A telescopic sleeve rod 302 is arranged inside the inner ring of the spring 301, and both ends of the telescopic sleeve rod 302 are fixedly connected with the upper end surface of the protective housing 303 and the lower end surface of the front end of the fixing frame 3 respectively. The lower end of the protective housing 303 is fixedly connected with a rubber ring 304;

[0022] The right side wall of the telescopic end of the first hydraulic rod 201 is fixedly connected with a connecting rod 4. The end of the connecting rod 4 is fixedly connected with a connecting frame 401. The lower end inside the connecting frame 401 is connected with a tool rest 402. The lower end surface of the tool rest 402 is fixedly connected with a blade 403. The two sides inside the tool rest 402 are rotatably connected with threaded bolts 404. The front end wall of the workbench 1 is fixedly connected with a fixing plate 8. The upper end inside the fixing plate 8 is fixedly connected with a third hydraulic rod 801. The telescopic end of the third hydraulic rod 801 is connected with a limiting plate 802. The right end of the workbench 1 is fixedly connected with a waste box 5.

[0023] In this embodiment: The raw materials for the production of the iron core are placed on the workbench 1, and then the stamping head 202 is driven downward by the first hydraulic rod 201 to perform stamping work on the iron core raw materials on the workbench 1. Then, when the stamping head 202 is driven downward, the protective housing 303 and the rubber ring 304 are also driven downward to contact the iron core raw materials. Through the downward extrusion of the rubber ring 304 at the lower end of the protective housing 303, the fixation of the iron core raw materials is achieved. At this time, the stamping head 202 continues to move downward to complete the stamping work. The protective housing 303 is slidably connected to the stamping head 202, and the protective housing 303 is compressed on the fixing frame 3 through the spring 301 and the telescopic sleeve rod 302 to achieve protection and fixation during stamping, effectively preventing the splashing and scattering of raw materials during stamping, reducing the operation risk. At the same time, the design of fixing the iron core raw materials with the rubber ring 304 also enhances the stability of the iron core raw materials during stamping, improving the stamping accuracy and product quality. After the iron core raw materials on the workbench 1 are stamped, the iron core waste continues to move to the right. When each stamping operation is performed, the connecting rod 4 fixedly connected to the side wall of the telescopic end of the first hydraulic rod 201 and the tool rest 402 connected to the lower end of the connecting frame 401 through the threaded bolt 404 move downward synchronously, driving the blade 403 downward to cut the waste after stamping and send it into the waste box 5.
