Description
Technical Field
[0001] This invention relates to the field of new energy motor winding processing technology, and in particular to a thin flat wire wave winding continuous bending device and bending method. Background Technology
[0002] Thin flat wire refers to flat copper wire with a thickness ranging from 0.1mm to 0.8mm and a width ranging from 2.4mm to 4mm, with a width-to-thickness ratio generally greater than 3:1. It is commonly used in the processing of (continuous) wave windings for stators of new energy motors. In stator windings, the bending of thin flat wire is mainly in the width direction. However, due to the large width-to-thickness ratio, the bent thin flat wire exhibits significant wrinkling and deformation at the bending points, making the bending process difficult and challenging to guarantee bending quality. Furthermore, in actual processing, to reduce welding, thin flat wire (continuous) wave windings typically use single thin flat wires for continuous bending, with each single thin flat wire exceeding 2 meters in length (actually ranging from 2 to 8 meters). Simultaneously, it is necessary to consider the cross-layer windings, resulting in inconsistent lengths of each bending segment and numerous bending angles, thus posing significant challenges to the winding processing of thin flat wire windings.
[0003] Therefore, how to achieve continuous bending of a single thin flat wire at multiple angles to form a thin flat wire (continuous) wave winding has become a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this invention is to solve the problems of high difficulty, poor consistency, low quality and low winding efficiency of thin flat wire windings. It provides a continuous bending device and bending method for thin flat wire wave windings, which is convenient and easy to wind, can efficiently and quickly wind thin flat wire wave windings, and has better winding consistency, thereby significantly improving the quality of the windings.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a thin flat wire wave winding continuous bending device, characterized in that: it includes a base plate, a positioning plate and a guide plate;
[0006] An arc-shaped scale layer is provided on the base plate. The scale layer includes a left scale layer and a right scale layer, both arc-shaped. The 0 scale line of the left scale layer and the right scale layer are located at adjacent ends and are spaced apart. The centers of the circles containing the left scale layer and the right scale layer are located on the same straight line and have the same radius. On the base plate, a positioning hole is provided at the center of the circles containing the left scale layer and the right scale layer, respectively.
[0007] The positioning plate has a width at one end greater than the width at the other end, forming a wide section and a narrow section. Two upper positioning holes are provided at the end of the wide section away from the narrow section. The positioning plate is detachably connected to the base plate via a rotating pin and can rotate around the pin. When the rotating pin is inserted into the upper positioning hole on the left side of the positioning plate and the lower positioning hole on the left side of the base plate, the left side of the narrow section of the positioning plate coincides with the 0 mark line of the left scale layer. Correspondingly, when the rotating pin is inserted into the upper positioning hole on the right side of the positioning plate and the lower positioning hole on the right side of the base plate, the right side of the narrow section of the positioning plate coincides with the 0 mark line of the right scale layer. A main groove is provided between the two lower positioning holes of the positioning plate. The main groove extends along the length of the positioning plate, and at least one branch groove is provided on one or both sides of the main groove. One end of the branch groove is connected to the main groove, and the other end penetrates the side edge of the positioning plate.
[0008] The guide plate is located on the side of the lower positioning hole away from the scale layer. Its length direction is perpendicular to the straight line where the center of the circle containing the left and right scale layers is located, and there is a gap between the guide plate and the adjacent end of the positioning plate. The guide plate has a guide groove that runs through both ends of it. When either side of the narrow section of the positioning plate coincides with the O scale line, the main groove on the positioning plate can be on the same straight line as the guide groove.
[0009] Furthermore, the central angles corresponding to the left and right scale layers are greater than or equal to 90°.
[0010] Furthermore, the width of the narrow segment is consistent with the distance between the two 0-mark lines, and the distance between the two lower positioning holes is consistent with the distance between the two upper positioning holes. When the two upper positioning holes and the two lower positioning holes are aligned, the two sides of the narrow segment coincide with the two mark lines respectively.
[0011] Furthermore, the guide plate includes a lower guide plate and an upper pressure plate, and the guide groove is located on the upper side of the lower guide plate.
[0012] Furthermore, the guide groove, main groove, and branch groove have the same width.
[0013] Furthermore, the connection between the branch trough and the main trough has an arc-shaped transition.
[0014] A method for continuous bending of thin flat wire wave windings, characterized by the following steps using the aforementioned bending device:
[0015] 1) Insert the thin flat wire into the guide groove and pass it through the guide groove;
[0016] 2) Select a suitable positioning plate according to the bending requirements of the thin flat wire, and insert the rotating pin into the corresponding ground positioning hole and lower positioning hole on the positioning plate and the base plate according to the bending direction;
[0017] 3) Manually guide the thin flat wire into the corresponding primary bending branch groove according to the bending requirements, and press the thin flat wire into the main groove and the primary bending branch groove; rotate the positioning plate, and the thin flat wire bends at the position of the rotating pin until it is rotated to the set angle to complete the first bend;
[0018] 4) Remove the rotating pin, then push the thin flat wire forward to remove it from the positioning plate. Then, according to the secondary bending requirements, reconnect the positioning plate to the base plate by rotating the pin.
[0019] 5) Manually guide the thin flat wire into the secondary bending branch groove, and press the thin flat wire into the main groove and the secondary bending branch groove; rotate the positioning plate again until it reaches the set angle to complete the secondary bending.
[0020] 6) Repeat steps 4) and 5) until the single-layer winding bending is completed;
[0021] 7) Repeat steps 3) to 6) until the bending of the entire winding is completed.
[0022] Furthermore, in step 3), during the first bend, the length from the end of the flat wire to the pin position needs to be customized according to the required length of the straight segment of the thin flat wire, so as to achieve the required length of the straight segment of the thin flat wire for the first bend.
[0023] Furthermore, in step 5), during the second bending, the thin flat wire is pressed into the corresponding branch groove for bending according to the bending requirements, so as to ensure the length of the straight section between the bending sections of the thin flat wire.
[0024] Compared with the prior art, the present invention has the following advantages:
[0025] 1. This invention employs an innovative process method, which uses guide grooves in the guide plate for straightening; different branch grooves on the positioning plate to control the bending length; and a dial on the base plate to control the bending angle, thereby improving the consistency and accuracy of continuous bending of thin flat wire wave windings and improving the winding quality.
[0026] 2. The positioning plate in this invention is more slippery, which makes it easier to select and adjust according to different bending angles, spacings, etc., and has strong compatibility.
[0027] 3. When used for sample winding production, this invention has a lower bending difficulty coefficient, higher winding efficiency, and lower implementation cost compared to other equipment. Attached Figure Description

[0037] Example: See Figures 1 to 5 A thin flat wire wave winding continuous bending device includes a base plate 1, a positioning plate 2 and a guide plate.
[0038] An arc-shaped scale layer 3 is provided on the base plate 1. During actual processing, the base plate 1 is semi-circular in shape, and the scale layer 3 is located on the side of the base plate 1 closest to the semi-circle (arc shape). The scale layer 3 includes an arc-shaped left scale layer 3 and a right scale layer 3, wherein the 0-degree mark of the left and right scale layers 3 are located at adjacent ends and are spaced apart. The centers of the circles containing the left and right scale layers 3 are on the same straight line, and the radii of the circles are equal. In practice, the straight line containing the centers of the two scale layers 3 is parallel to the straight side (straight edge) of the base plate 1. On the base plate 1, corresponding to the centers of the circles containing the left and right scale layers 3, a positioning hole 4 is provided. In practice, the central angles corresponding to the left and right scale layers 3 are greater than or equal to 90°, thereby ensuring accurate bending even when the positioning plate 2 rotates at a large angle.
[0039] The positioning plate 2 has a width at one end greater than the width at the other end, forming a wide segment and a narrow segment. Two upper positioning holes 5 (left upper positioning hole 5 and right upper positioning hole 5) are provided along the width direction at the end of the wide segment away from the narrow segment. The distance between the upper positioning hole 5 and the end of the wide segment near the narrow segment is less than the distance between the lower positioning hole 4 and the corresponding 0 mark. The positioning plate 2 is detachably connected to the base plate 1 via a rotating pin 6. The rotating pin 6 is inserted into the corresponding upper positioning hole 5 and lower positioning hole 4, and the positioning plate 2 can rotate around the rotating pin 6. When the rotating pin 6 is inserted into the upper positioning hole 5 on the left side of the positioning plate 2 and the lower positioning hole 4 on the upper left side of the base plate 1, the left side of the narrow segment of the positioning plate 2 coincides with the 0 mark of the left scale layer 3. Correspondingly, when the rotating pin 6 is inserted into the upper positioning hole 5 on the right side of the positioning plate 2 and the lower positioning hole 4 on the upper right side of the base plate 1, the right side of the narrow segment of the positioning plate 2 coincides with the 0 mark of the right scale layer 3. Preferably, the width of the narrow segment is consistent with the distance between the two 0 scale lines, and the distance between the two lower positioning holes 4 is consistent with the distance between the two upper positioning holes 5. When the two upper positioning holes 5 and the two lower positioning holes 4 are aligned, the two sides of the narrow segment coincide with the two scale lines respectively.
[0040] A main groove 7 is provided between the two lower positioning holes 4 of the positioning plate 2. The main groove 7 extends along the length of the positioning plate 2, and at least one branch groove 8 is provided on one or both sides of the main groove 7. One end of the branch groove 8 is connected to the main groove 7, and the other end passes through the side edge of the positioning plate 2. As an optimization, the main groove 7 is located in the middle of the width direction of the positioning plate 2, and the distance between its two sides and the two sides of the positioning plate 2 is equal. In practice, the angle between the branch groove 8 and the main groove 7, and the distance between the branch groove 8 and the end of the wide section of the positioning plate 2 (the end connected to the rotating pin 6) are set and processed according to the bending requirements. In the actual manufacturing process, as needed, there are multiple positioning plates 2. The distribution positions of the branch grooves 8 on the multiple positioning plates 2 and the angles between them and the main groove 7 are different, so different positioning plates 2 can be selected according to different bending requirements.
[0041] The guide plate is located on the side of the lower positioning hole 4 away from the scale layer 3. Its length direction is perpendicular to the straight line containing the centers of the circles of the left and right scale layers 3, and there is a gap between the guide plate and the adjacent end of the positioning plate 2. The guide plate has a guide groove 9 that runs through both ends of it. When either side of the narrow section of the positioning plate 2 coincides with the O scale line, the main line groove 7 on the positioning plate 2 can be aligned with the guide groove 9. The guide plate includes a lower guide plate 10 and an upper pressure plate 11, and the guide groove 9 is located on the upper side of the lower guide plate 10. To further improve the pressing effect of the upper pressure plate 11 on the thin flat wire, a pressure block is provided on the lower side of the upper pressure plate 11 corresponding to the guide groove 9. The length direction of the pressure block is consistent with the guide groove 9. In practice, the end of the upper pressure plate 11 near the positioning plate 2 extends above the positioning plate 2 (forming a clearance fit with the positioning plate 2), thereby preventing the positioning plate 2 from moving up and down during the swinging process, so as to achieve vertical positioning of the positioning plate 2. During processing, the lower guide plate 10 is connected to the base plate 1 via connecting bolts 12, and the upper pressure plate 11 is connected to the lower guide plate 10 via connecting bolts 12. The lower guide plate 10 has countersunk holes corresponding to the connecting bolts 12, and the connecting bolts 12 between the lower guide plate 10 and the base plate 1 are located within these countersunk holes, with their upper ends penetrating the lower guide plate 10 and abutting against the upper pressure plate 11. Thus, by adjusting the two connecting bolts 12, the distance between the upper pressure plate 11 and the lower guide plate 10 can be adjusted, thereby adjusting the height of the guide groove 9 to facilitate the movement of the thin flat wire. To improve the relative stability between the guide plate and the base plate 1, a positioning pin 13 is also provided between the base plate 1, the lower guide plate 10, and the upper pressure plate 11. In actual processing, the widths of the guide groove 9, the main wire groove 7, and the branch wire groove 8 are consistent (as an optimization, this width is consistent with the width of the thin flat wire). The connection between the branch wire groove 8 and the main wire groove 7 has an arc transition to avoid stress concentration at the corner of the thin flat wire during bending.
[0042] A method for continuous bending of thin flat wire wave windings, utilizing the aforementioned bending device, includes the following specific steps:
[0043] 1) Insert the thin flat wire into the guide groove 9 and pass it through the guide groove 9.
[0044] 2) Select a suitable positioning plate 2 according to the bending requirements of the thin flat wire, and insert the rotating pin 6 into the corresponding ground positioning hole 5 and lower positioning hole 4 on the positioning plate 2 and the base plate 1 according to the bending direction;
[0045] 3) Manually guide the thin flat wire into the corresponding primary bending branch groove 8 according to the bending requirements, and press the thin flat wire into the main wire groove 7 and the primary bending branch groove 8; rotate the positioning plate 2, and the thin flat wire bends at the position of the rotating pin 6 (during the bending process, the thin flat wire on the positioning plate 2 is pressed down, so that the thin flat wire moves towards the main wire groove 7 through the guide groove 9 as the positioning plate 2 rotates, in order to adapt to the bending requirements. At the same time, due to the action of the upper pressure plate 11, the thin flat wire can be prevented from lifting during the bending process, thereby locking it in the wire groove to improve the stability during the bending process), until it is rotated to the set angle, and the first bend is completed. For the first bend, the length from the end of the flat wire to the pin position needs to be customized according to the required straight section length of the thin flat wire to achieve the required straight section length of the thin flat wire for the first bend.
[0046] 4) Remove the rotating pin 6, then push the thin flat wire forward to remove it from the positioning plate 2. Then, according to the secondary bending requirements, reconnect the positioning plate 2 to the base plate 1 by rotating the pin 6.
[0047] 5) Manually guide the thin flat wire into the secondary bending branch groove 8, and press the thin flat wire into the main wire groove 7 and the secondary bending branch groove 8; rotate the positioning plate 2 again until it reaches the set angle to complete the secondary bending. During the secondary bending, the thin flat wire is pressed into the corresponding branch groove 8 for bending according to the bending requirements, so as to ensure the length of the straight section between the bending sections of the thin flat wire.
[0048] 6) Repeat steps 4) and 5) until the single-layer winding bending is completed;
[0049] 7) Repeat steps 3) to 6) until the bending of the entire winding is completed.
[0050] In one specific embodiment, this solution uses five positioning plates 2, numbered 1, 2, 3, 4, and 5 in sequence. The branch grooves 8 on each positioning plate 2 are also numbered 1, 2, 3… The numbering of the branch grooves 8 on the five positioning plates 2 is consecutive. During the bending process, the branch grooves 8 are bent sequentially according to their numbers. Specifically: First, select the positioning plate 2 containing branch groove 8 number 1. Then, lay the thin flat wire (not shown in the figure) flat and insert it into the guide groove 9, pushing the copper wire out of the guide groove 9. The length of the first bending section needs to be measured with a ruler to determine the wire feeding length. Bend according to the bending diagram (not shown in the figure) (e.g., bend 10° to the left): Insert the rotating pin 6 into the upper positioning hole 5 on the left side of the positioning plate 2 and the corresponding underground positioning hole 4 on the bottom plate. Rotate the positioning plate 2 10° to the left. When the scale line on the bottom plate 1 coincides with the narrow edge line of the handle on the positioning plate 2, the angle rotation is complete. After the angle is reached, pull out the rotating pin 6, gently push the copper wire, remove the positioning plate 2, and determine whether the No. 2 branch groove 8 is on the positioning plate 2. If it is, reconnect the positioning plate 2 to the base plate 1 by rotating the pin 6. If it is not, replace the positioning plate 2 where the No. 2 branch groove 8 is located, and connect it to the base plate 1 by rotating the pin 6. Then, place the first bent section of the bent thin flat wire into the No. 2 branch groove 8 set on the positioning plate 2 (e.g., ...). Figure 4 As shown in the diagram, after flattening, rotate the positioning plate 2 for a second bend. Repeat the above steps until the entire winding is completed. During the process, the bending length is controlled by the branch groove 8 on the positioning plate 2, and the bending angle is controlled by the scale on the base plate 1; thus, the consistency of the winding process can be ensured, thereby improving the quality of the continuous wave winding.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of the present invention without departing from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
