Technical Field

[0001] The present invention relates to a mold, and more particularly to a transfer profiling mold. Background Art

[0002] Currently, in the production of new energy vehicle motors, in order to improve the efficiency of motor products, flat wire hairpins are beginning to be used instead of round electromagnetic wires. When the flat wire hairpins are assembled in the motor, they need to be inserted into the stator core of the motor in a specific manner. In the actual production process, the flat wire hairpins are not directly inserted into the stator core, but need to be pre-inserted to form a wire crown, and then the whole is transferred to the corresponding station for easy insertion into the stator core. Therefore, in view of the above problems, it is necessary to propose a further solution. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, an embodiment of the present invention provides a transfer profiling die, which includes: a transfer outer cylinder 10, a transfer inner cylinder 20, and a base 30.

[0022] As shown Figure 2 , 3 The transfer inner cylinder 20 is installed on the base 30 and can be further assembled into the corresponding production line through the base 30. To facilitate the connection between the transfer inner cylinder 20 and the base 30, a flange 21 for facilitating the installation and fixation of the transfer inner cylinder 20 is provided at the lower end of the transfer inner cylinder 20. At this time, the flange 21 is fitted into the base 30.

[0023] To facilitate the installation and fixation of the base 30, limit blocks 32 are also provided at the four corner positions of the base 30. With the assistance of the limit blocks 32, the base 30 can be fixed to the corresponding fixing surface by bolts. In addition, positioning holes 33 are provided on the base 30 on both sides of the transfer inner cylinder 20. Correspondingly, positioning pins that can cooperate with the positioning holes are provided on the fixing surface where the base 30 is located.

[0024] The transfer inner cylinder 20 has a cavity 22 for facilitating the accommodation of flat wire hairpins. At the same time, a plurality of inner insertion holes 23 arranged circumferentially around the center are provided at the top of the transfer inner cylinder 20, and the plurality of inner insertion holes 23 are communicated with the cavity 22. In this way, the flat wire hairpins pass through the transfer outer cylinder 10 and are further inserted into the corresponding inner insertion holes 23.

[0025] As shown Figure 4 , the transfer outer cylinder 10 can be sleeved on the transfer inner cylinder 20, and the two are coaxially arranged. A plurality of outer insertion holes 11 arranged circumferentially around the center are provided at the top of the transfer outer cylinder 10, and the plurality of outer insertion holes 11 are correspondingly arranged with the plurality of inner insertion holes 23. In this way, under the clamping action of the manipulator in the production line, the flat wire hairpins can be inserted into the outer insertion holes 11 and the inner insertion holes 23 one by one. Since the outer insertion holes 11 and the inner insertion holes 23 are arranged circumferentially around the center, the flat wire hairpins inserted into the outer insertion holes 11 and the inner insertion holes 23 form an annular structure, that is, the initial form of the wire crown 100 is formed.

[0026] To facilitate the insertion of the flat wire hairpins, a plurality of outer insertion holes 11 are located at the bottom of an annular groove 12. At this time, the two inner side walls of the annular groove 12 form guiding surfaces 120. Specifically, the distance between the two guiding surfaces 120 gradually decreases along the insertion direction of the flat wire hairpin, so as to facilitate the introduction of the flat wire hairpin during insertion. At the same time, the edge of the opening of the annular groove 12 is designed as an arc-shaped chamfer structure.

[0027] In addition, the base 30 has an opening 34 communicated with the cavity 22 of the transfer inner cylinder 20, and the size of the opening 34 is equivalent to the diameter of the transfer inner cylinder 20. In this way, by providing the above-mentioned opening 34, it is convenient for the expansion mechanism in the production line to extend into the transfer inner cylinder 20 to push the flat wire hairpins inserted into the transfer inner cylinder 20 to the required position so as to form the required shape of the wire crown 100.

[0028] The transfer outer cylinder 10 can move in the axial direction and be separated from the transfer inner cylinder 20. In this way, with the help of the transfer outer cylinder 10, the overall turnover of the wire crown 100 can be facilitated, and it can be integrally inserted and combined into the stator core of the motor, thus significantly improving the insertion and turnover efficiency of the flat wire hairpin. In addition, in order to facilitate the turnover of the transfer outer cylinder 10, an annular extension 13 suitable for the transfer outer cylinder 10 to be grasped is provided on the outer peripheral side wall of the transfer outer cylinder 10.

[0029] In summary, the transfer profiling die of the present invention can facilitate the insertion and assembly of the flat wire hairpin and further form the wire crown shape. At the same time, the transfer profiling die of the present invention also has a separable transfer outer cylinder. With the help of this transfer outer cylinder, the overall turnover of the wire crown can be facilitated, and it can be integrally inserted and combined into the stator core of the motor, thus significantly improving the insertion and turnover efficiency of the flat wire hairpin.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
