Description

Technical Field

[0001] The present invention relates to an insulating paper forming device in an insulating paper insertion mechanism, and more specifically, to a new energy flat wire stator slot bottom insulating paper cold forming die and a forming method thereof. Background Art

[0002] The insulating paper cold forming mold is a mold used to process insulating paper into a specific shape at room temperature. The principle is to apply pressure to the insulating paper so that the insulating paper can be folded in the forming cavity and plastically deformed according to the shape of the forming cavity, so that the insulating paper can be folded into the required shape for insertion into the stator slot to meet the processing requirements.

[0003] The insulating paper cold forming mold on the market usually includes an upper mold and a lower mold. The upper mold and the lower mold are assembled together to form a mold cavity for forming the insulating paper. The insulating paper is plastically deformed in the mold cavity and then ejected.

[0004] At present, although the insulation paper cold forming molds on the market can realize the forming of insulation paper, the forming speed of the insulation paper is slow, and the insulation paper insertion mechanism needs to insert the folded insulation paper into each slot of the stator coil in turn. The production scale is large. If the insulation paper folding and forming speed is slow, it may not be able to meet the high production cycle requirements, which limits the improvement of production efficiency and increases the time cost of production. In addition, during the processing, the insulation paper is easy to conflict with the side wall of the forming mold and thus damaged, affecting the qualified rate of the finished product. Summary of the invention

[0009] The present invention is further configured as follows: the cutting mechanism includes a cutting motor arranged on a frame, a paper cutting disc arranged on the cutting motor, a connecting rod assembly arranged on the paper cutting disc, and a paper cutting knife arranged on the connecting rod assembly.

[0010] The present invention is further configured as follows: the installation structure includes a mounting plate arranged at the upper end of the origami mold and a stator plate arranged in the mounting plate, and a turntable is also provided between the stator plate and the mounting plate, and the turntable is configured to drive the stator of the paper inserting machine in the stator plate to rotate.

[0011] Preferably, the stator disk is further provided with a plurality of insertion holes, and the position and shape of each insertion hole matches the cross section of the paper feeding channel.

[0012] The present invention is further configured as follows: the forming card block group includes a first origami block and a second origami block, and the first origami block and the second origami block are both provided with an arc guide surface, and the arc guide surface is configured to interfere with the edge of the insulating paper and realize folding of the insulating paper.

[0013] Preferably, the arc-shaped guiding surface on the first origami block faces in opposite directions to the arc-shaped guiding surface on the second origami block.

[0014] The present application also provides a forming method of a cold forming mold for insulating paper at the bottom of a stator slot of a new energy flat wire, characterized in that the folding method of the insulating paper by the origami mold comprises the following steps: S1, the insulating paper passes through a feeding paper board, and the two ends of the insulating paper are folded for the first time by a folding mold on the feeding paper board;

[0015] S2, the paper insertion rod pushes the insulating paper from the paper feeding channel of the paper pushing mold into the paper feeding channel of the origami mold;

[0016] S3, the insulating paper contacts the arc-shaped guide surface of the first origami block and slides on the arc-shaped guide surface, so that the insulating paper on the first origami block is folded and forms a 90° angle with the original insulating paper;

[0017] S4, the paper insertion rod continues to push the insulating paper to slide, and the insulating paper moves to the second folding block;

[0018] S5, the insulating paper contacts the arc-shaped guide surface of the second folding block and slides on the arc-shaped guide surface, so that the insulating paper on the second folding block is folded and forms a 90° angle with the original insulating paper;

[0019] S6. The insulating paper is folded in the paper feeding channel to match the shape of the slots in the paper feeding channel and the stator of the paper inserting machine.

[0020] By adopting the above technical scheme, the beneficial effects are as follows: 1. By arranging a paper feeding structure, a paper inserting structure, a cutting structure and a mounting structure on the frame, the paper inserting machine stator is arranged in the mounting structure and can rotate in the mounting mechanism, so that the slot in the paper inserting machine stator can match the paper feeding channel of the paper inserting structure. At the same time, the insulating paper is moved to the cutting structure through the paper feeding structure for cutting and pushed into the paper inserting structure, and the folding is completed in the paper feeding channel on the paper inserting structure so that the shape of the insulating paper matches the shape of the paper feeding channel, and the cross-sectional shape of the paper feeding channel matches the slot of the paper inserting machine stator, so that the folded insulating paper in the paper feeding channel can be conveniently pushed into the slot of the paper inserting machine stator, the processing is convenient, the processing efficiency is high, and during the processing, the cutting structure, the paper inserting mechanism and the paper feeding structure can move synchronously, which improves the production speed and meets the needs of mass production.

[0021] 2. Further, in order to realize the folding and forming of the insulating paper during the processing, generally speaking, since the slot shape of the stator of the paper inserting machine is square, the insulating paper needs to be folded 3 times to form a square matching the paper feeding channel. At the same time, when the insulating paper passes through the paper feeding board, since the two sides of the paper feeding board are provided with folding molds, the folding mold has a guide block and a folding block, and a guide slope is provided on one side of the guide block, and the guide slope faces the paper feeding direction of the insulating paper. When the insulating paper enters the folding mold, the edge of the insulating paper conflicts with the guide slope and gradually rises, which facilitates the conflict between the insulating paper and the folding block. Specifically, when the insulating paper moves After moving to the folding block, the folding block further contacts the insulating paper. At the same time, since the folding block has a folding arc surface for folding the insulating paper, the insulating paper is guided and folded by the folding arc surface, and the overall angle of the folding arc surface is gentle, which reduces the friction with the insulating paper during the folding process, prevents the insulating paper from being damaged during the folding process, improves the production qualification rate, and reduces the cost. Moreover, after the first folding of the insulating paper is completed, the cutting structure is cut into a suitable shape and pushed into the molding structure for molding, so that the insulating paper can be molded into a suitable shape before being inserted into the slot of the stator of the paper inserting machine, thereby improving the processing efficiency and having good practicality.

[0022] 3. Meanwhile, to facilitate the overall cutting process, the cutting mechanism cuts the insulating paper by the reciprocating movement of the paper cutting knife, enabling continuous cutting of the insulating paper in cooperation with the paper feeding structure. This results in good usage effects, ensures that the sizes of the cut insulating papers are the same, and further, the time consumption for paper feeding, cutting, folding, and inserting of the insulating paper is similar, enabling fast paper insertion speed for a single slot, meeting the production rhythm requirements, and achieving high overall processing efficiency to meet the production needs of the stator of the paper inserting machine.

[0023] 4. Moreover, during the process of folding and forming the insulating paper within the forming mechanism, by arranging a forming block group within the paper feeding channel of the forming mechanism, the forming block group has a first folding block and a second folding block. When the insulating paper passes through the first folding block, the insulating paper抵触 the arc guiding surface of the first folding block, folds, and forms a 90° angle with the original insulating paper under the limitation of the paper feeding channel. The shape of the insulating paper within the paper feeding channel is an "L" shape. Subsequently, the insulating paper is continuously pushed, causing it to抵触 the arc guiding surface of the second folding block and fold again to form a 90-degree angle with the original insulating paper. At this time, the shape of the insulating paper within the paper feeding channel is a "ㄈ" shape. And because the insulating paper has been folded for the first time by the folding block before being inserted into the forming mechanism, the surface formed after the first folding cooperates with the surface formed by folding within the paper feeding channel, making the shape of the insulating paper within the paper feeding channel a "口" shape that matches the cross-section of the paper folding channel. The folding of the insulating paper is automatically completed by the first folding block and the second folding block, with a simple structure, convenient processing, and high overall automation level. At the same time, the arc guiding surfaces on the first folding block and the second folding block face in opposite directions, effectively preventing damage to the insulating paper during the folding process and affecting the quality of the finished product.

[0041] Preferably, the arc-shaped guiding surface 643 on the first origami block 641 and the arc-shaped guiding surface 643 on the second origami block 642 face in opposite directions.

[0042] The present application also provides a forming method of a cold forming mold for insulating paper at the bottom of a stator slot of a new energy flat wire, characterized in that the folding method of the insulating paper by the origami mold 62 comprises the following steps: S1, the insulating paper passes through a paper feeding board 22, and the two ends of the insulating paper are folded for the first time by a folding mold 23 on the paper feeding board 22;

[0043] S2, the paper insertion rod 31 pushes the insulating paper from the paper feeding channel 63 of the paper pushing mold 61 into the paper feeding channel 63 of the paper folding mold 62;

[0044] S3, the insulating paper contacts the arc-shaped guide surface 643 of the first folding paper block 641 and slides on the arc-shaped guide surface 643, so that the insulating paper on the first folding paper block 641 is folded and forms a 90° angle with the original insulating paper;

[0045] S4, the paper insertion rod 31 continues to push the insulating paper to slide, and the insulating paper moves to the second folding block 25;

[0046] S5, the insulating paper contacts the arc-shaped guide surface 643 of the second folding block 25 and slides on the arc-shaped guide surface 643, so that the insulating paper on the second folding block 642 is folded and forms a 90° angle with the original insulating paper;

[0047] S6. The insulating paper is folded in the paper feeding channel 63 and matches the shape of the slots of the paper feeding channel 63 and the stator of the paper inserting machine.

[0048] By providing a paper feeding structure 2, a paper inserting structure 3, a cutting structure 4 and a mounting structure 5 on the frame 1, the paper inserting machine stator is arranged in the mounting structure 5 and can rotate in the mounting mechanism, so that the slot in the paper inserting machine stator can match the paper feeding channel 63 of the paper inserting structure 3. At the same time, the insulating paper is moved to the cutting structure 4 through the paper feeding structure 2 for cutting and pushed into the paper inserting structure 3, and the folding is completed in the paper feeding channel 63 on the paper inserting structure 3 so that the shape of the insulating paper matches the shape of the paper feeding channel 63, and the cross-sectional shape of the paper feeding channel 63 matches the slot of the paper inserting machine stator, so that the folded insulating paper in the paper feeding channel 63 can be conveniently pushed into the slot of the paper inserting machine stator, the processing is convenient, the processing efficiency is high, and during the processing, the cutting structure 4, the paper inserting mechanism and the paper feeding structure 2 can move synchronously, which improves the production speed and meets the needs of mass production.

[0049] Furthermore, in order to realize the folding and forming of the insulating paper during the processing, generally speaking, since the slot shape of the stator of the paper inserting machine is square, the insulating paper needs to be folded three times to form a square matching the paper feeding channel 63. At the same time, when the insulating paper passes through the paper feeding paper board 22, since the paper feeding paper board 22 is provided with folding molds 23 on both sides, the folding mold 23 has a guide block 24 and a folding block 25, and a guide bevel 26 is provided on one side of the guide block 24. The guide bevel 26 faces the paper feeding direction of the insulating paper. When the insulating paper enters the folding mold 23, the edge of the insulating paper conflicts with the guide bevel 26 and gradually rises, which facilitates the conflict between the insulating paper and the folding block 25. Specifically, When the insulating paper moves to the folding block 25, the folding block 25 further contacts the insulating paper. At the same time, since the folding block 25 has a folding arc surface 27 for folding the insulating paper, the insulating paper is guided and folded by the folding arc surface 27, and the overall angle of the folding arc surface 27 is gentle, which reduces the friction with the insulating paper during the folding process and prevents the insulating paper from being damaged during the folding process, thereby improving the production qualification rate and reducing the cost. Moreover, after the first folding of the insulating paper is completed, the cutting structure 4 is cut into a suitable shape and pushed into the molding structure 6 for molding, so that the insulating paper can be molded into a suitable shape before being inserted into the slot of the stator of the paper inserting machine, thereby improving the processing efficiency and having good practicality.

[0050] At the same time, in order to facilitate the cutting process of the whole, the cutting mechanism cuts the insulating paper through the reciprocating motion of the paper cutter, and the processing is continuous. It can cooperate with the paper feeding structure 2 to form continuous cutting of the insulating paper, and the use effect is good. It can make the cut insulating paper have the same size. Furthermore, the time consumption of feeding, cutting, folding and inserting the insulating paper is similar, so that the paper insertion speed of a single slot is fast, which meets the production rhythm requirements, and the overall processing efficiency is high, which meets the production requirements for the stator of the paper inserting machine.

[0051] Furthermore, in the process of folding and forming the insulating paper in the forming mechanism, a forming block group 64 is arranged in the paper feeding channel 63 of the forming mechanism, and the forming block group 64 has a first folding block 641 and a second folding block 642. When the insulating paper passes through the first folding block 641, the insulating paper contacts the arc-shaped guide surface 643 of the first folding block 641, and the insulating paper is folded and forms a 90° angle with the original insulating paper under the limitation of the paper feeding channel 63. The shape of the insulating paper in the paper feeding channel 63 is "L"-shaped, and then the insulating paper is continued to be pushed so that the insulating paper contacts the arc-shaped guide surface 643 of the second folding block 25, and is folded again to form a 90-degree angle with the original insulating paper. At this time The shape of the insulating paper in the paper feeding channel 63 is a "ㄈ" shape, and because the insulating paper is folded for the first time through the folding block 25 before being inserted into the molding mechanism, the surface formed after the first folding cooperates with the surface formed by folding in the paper feeding channel 63, so that the shape of the insulating paper in the paper feeding channel 63 is a "mouth" shape that matches the cross-section of the paper folding channel. The folding of the insulating paper is automatically completed by the first folding block 25 and the second folding block 25. The structure is simple, the processing is convenient, and the overall degree of automation is high. At the same time, the arc guide surface 643 on the first paper folding block 641 and the arc guide surface 643 on the second paper folding block 642 face oppositely, which can effectively prevent the insulating paper from being damaged during the folding process and affect the effect of the finished product.
