Description

Technical Field

[0001] This application relates to the field of brush plate technology, and more specifically to a stamping structure that is easy to separate. Background Technology

[0002] High-elasticity brass sheets are the core support component of the brush. Their elasticity generates pressure towards the center, ensuring tight contact between the brush and the commutator or slip ring. Brush copper sheets are mostly formed by stamping.

[0003] There is a type of stamped copper brush sheet, such as Figure 1 As shown, the device includes a strip body 90 and stamped parts 91. The strip body 90 has several rectangularly arranged slots 901, and each slot 901 is connected to a stamped part 91. In the prior art, the copper sheets for the brush are obtained by manually breaking the stamped parts 91. However, in mass production, breaking the stamped parts 91 one by one is inefficient and there is room for improvement.

[0004] Therefore, there is a need for an easily separable stamping structure that facilitates the simultaneous separation of multiple stamping parts and helps improve production efficiency. Summary of the Invention

[0020] Schematic diagram of easily separable stamped part structure, reference Figure 2 and Figure 3 According to a preferred embodiment of the present invention, an easily separable stamping part structure includes a strip body 10 and a stamping part 20.

[0021] Specifically, the strip body 10 has a plurality of rectangular arrayed slots 101; each slot 101 is provided with a stamping part 20, and one end of the stamping part 20 is connected to the strip body 10. The strip body 10 also has a plurality of grooves 102, which are located on both sides of the connection between the stamping part 20 and the strip body 10. Each groove 102 is collinear in the length direction of the strip body 10, and the lowest point of the groove 102 is lower than the height of the connection between the stamping part 20 and the strip body 10.

[0022] It should be noted that by creating the groove 102, the height of the connection between the stamped part 20 and the strip body 10 is higher than the height of the strip body 10 at the same horizontal line. Therefore, when separating the stamped part 20, the strip body 10 can be fixed first. Then, a guillotine can be used to cut downwards along the groove 102. Since the height of the connection between the stamped part 20 and the strip body 10 is higher than the groove 102, the guillotine cuts off the connection between each stamped part 20 and the strip body 10 first, thus separating each stamped part 20. It is evident that compared to the prior art, which requires manually breaking off each stamped part 20 one by one, this application, by setting the groove 102 to create a height difference between the stamped part 20 and the strip body 10, allows each stamped part 20 to be cut off at once by an external guillotine. This has the advantage of facilitating the simultaneous separation of multiple stamped parts 20, thus improving production efficiency.

[0023] Specifically, in this application, the groove 102 is a concave arc groove. When the stamping die punches out the outer contour of the stamped part 20, it simultaneously punches out the groove 102 at the corresponding position on the strip body 10.

[0024] In addition, the reason why the stamping part 20 is not directly broken during the stamping stage is due to the structural considerations of the stamping part 20 itself.

[0025] Specifically, the stamped part 20 includes a root portion 201, a bent portion 202, and a brush needle portion 203. The brush needle portion 203 is located between the root portion 201 and the bent portion 202. The root portion 201 and the bent portion 202 are arranged opposite to each other, and the end of the bent portion 202 away from the brush needle portion 203 is bent at a predetermined angle. The end of the root portion 201 away from the brush needle portion 203 is connected to the strip body 10.

[0026] It is evident that, to facilitate bending of the bent portion 202 on the stamped part 20 by the processing personnel, the stamped part 20 remains connected to the strip body 10 when the stamping die punches out the outer contour of the stamped part 20. Subsequently, the processing personnel or an external bending device bends the bent portion 202, positioning one end of the bent portion 202 above the root portion 201. Then, each of the stamped parts 20 on the strip body 10 is cut off by a guillotine cutter.

[0027] Furthermore, to secure the hopper body, the conveyor belt body 10 has a plurality of fixing holes 103, facilitating the placement of the conveyor belt body 10 during cutting.

[0028] Furthermore, to facilitate easier cutting of the strip body 10 at the groove 102 when necessary, the strip body 10 has notches 104 at both ends, and the notches 104 are collinear with the groove 102.

[0029] It should also be noted that, when the external stamping die punches out the groove 102, in order to avoid deformation at the connection between the groove 102 and the root 201, there is a material removal notch 1021 between the groove 102 and the root 201, so as to separate the root 201 from the groove 102.

[0030] In addition, in this embodiment, each of the empty slots 101 is a rectangular slot, and the end of the empty slot 101 away from the root 201 has a first extension slot 1011, and the end of the empty slot 101 opposite to the brush needle portion 203 has a second extension slot 1012, which provides conditions for obtaining the bent portion 202 and the brush needle portion 203.

[0031] In summary, the easily separable stamping structure based on the embodiments of this application is explained, which provides advantages such as facilitating the simultaneous separation of multiple stamping parts and contributing to improved production efficiency.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
