Description

Technical Field

[0001] The utility model relates to the technical field of flat wire forming, in particular to a flat wire integrated forming die. Background Art

[0002] Flat wire winding technology is a motor design technique that uses flat wire instead of traditional round wire. It demonstrates significant advantages in improving motor efficiency, reducing volume and increasing power density, improving performance stability, optimizing NVH performance, and providing efficient end cooling solutions. It is a key technological trend in the development of electric vehicles and industrial motors. The flat wire used in flat wire winding, also known as flat wire, flattened wire, flat-angle wire, or ultra-narrow strip, has unique advantages over common round wire in terms of heat dissipation, welding contact area, fatigue resistance, and hardness control.

[0003] The flat wire winding is composed of multiple single-strand flat wires, which are mainly made by stamping. The flat wire stamping die in the existing technology can only perform stamping in one direction when stamping straight flat wires. For flat wires that require different angles, the stamped flat wires need to be processed twice. This requires the stamped flat wires to be removed and then sent to other specific stamping equipment for secondary stamping, which reduces the processing efficiency of the flat wires.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model provides a flat wire integral forming mold, including a base 1 and a top plate 2. Four columns 14 are fixedly provided on the base 1. A sliding sleeve 15 is installed at the corresponding position of the surface of the top plate 2. The sliding sleeve 15 is slidably provided on the surface of the column 14. An upper mold base 3 is fixedly provided on the bottom of the top plate 2. A lower mold base 4 is fixedly provided on the surface of the base 1. A side mold base 5 is horizontally slidably provided on the surface of the base 1. A first protrusion 6 for forming the flat wire is provided on the surface of the side mold base 5. A second protrusion 7 is provided on the bottom of the upper mold base 3. The second protrusion 7 and the first protrusion 6 has the same horizontal projection position, and the surfaces of the second raised portion 7 and the first raised portion 6 are both provided with a smooth section 8 and a bent section 9, the smooth section 8 is set as a slope, and the bent section 9 is set in the middle of the two smooth sections 8, and the height of the bent section 9 is lower than the smooth section 8, and the bent section 9 and the smooth section 8 are transitioned by a curved surface, and the side surfaces of the first raised portion 6 and the second raised portion 7 are completely fitted to the inner wall of the lower mold base 4, and the top of the top plate 2 and the side surfaces of the side mold base 5 are respectively fixed with a first connecting portion 12 and a second connecting portion 13 for connecting to the power equipment.

[0025] See also Figure 1 、 2, 3, 4 and 5, first place the middle position of the flat wire body 17 on the side of the side mold base 5, and then drive the side mold base 5 to move horizontally toward the inside of the lower mold base 4 through the power equipment and the second connecting part 13. During this process, the side mold base 5 can cooperate with the lower mold base 4 to stamp the flat wire body 17 in the horizontal direction, and then keep the horizontal position of the side mold base 5 stationary, and drive the top plate 2 downward through the power equipment and the first connecting part 12, so that the top plate 2 drives the upper mold base 3 to move downward, so that the upper mold base 3 drives the second protrusion 7 into the gap between the lower mold base 4 and the side mold base 5. At this time, the gap between the first protrusion 6, the second protrusion 7, the side mold base 5 and the lower mold base 4 can stamp the flat wire body 17 in the vertical direction, and the smooth section 8 and the bent section 9 can respectively shape the surface of the flat wire body 17.

[0026] It should be noted that the specific shape of the bending section 9 needs to be set according to the shape of the flat wire body 17 to be formed. This embodiment does not provide one or several specific shapes of the bending section 9. The shape of the bending section 9 in the figure is only used for illustration.

[0027] A limit seat 10 is fixedly provided on the surface of the base 1 , and a notch 11 is provided on the surface of the limit seat 10 . The notch 11 contacts the surface of the side mold base 5 , and the top of the notch 11 is provided with the same slope as the smooth section 8 .

[0028] See also Figure 6 The side mold base 5 can translate between the two limit seats 10 when moving, and through the setting of the notch 11, the movement process of the side mold base 5 can be limited from the side of the side mold base 5 to prevent the side mold base 5 from being offset during the translation process, which will affect the molding of the flat wire body 17.

[0029] The side edges of the opening of the lower die base 4 are set to be rounded, and two handles 16 are symmetrically installed on the base 1.

[0030] See also Figure 1 and 3 The rounded corners are set to reduce the paint peeling caused by the friction between the flat wire body 17 and the opening of the lower mold base 4 when the side mold base 5 drives the flat wire body 17 to move horizontally. The rounded corners can well transition the flat wire body 17 so that it can smoothly enter the lower mold base 4, and the setting of the handle 16 is to facilitate the movement of the base 1 as a whole.

[0031] Working principle: When in use, the middle position of the flat wire body 17 is placed on the side of the side mold base 5. The power device pushes the flat wire body 17 into the lower mold base 4 through the side mold base 5, and the flat wire body 17 is formed in the horizontal direction through the cooperation of the lower mold base 4 and the side mold base 5. Then, the power device drives the upper mold base 3 to move downward, so that the upper mold base 3 drives the second protrusion 7 to enter the gap between the lower mold base 4 and the side mold base 5. The flat wire body 17 is formed in the vertical direction through the upper mold base 3, the lower mold base 4 and the side mold base 5, thereby realizing continuous forming of the flat wire body 17;

[0032] Specifically, the horizontal stamping between the lower die base 4 and the side die base 5 can first stamp the flat wire body 17 in the horizontal direction. At this time, the side die base 5 needs to remain stationary, and the upper die base 3 drives the second protrusion 7 to press down. The bottom of the flat wire body 17 is located on the first protrusion 6. When the flat wire body 17 is squeezed by the second protrusion 7, the second protrusion 7 and the first protrusion 6 will stamp the flat wire body 17 in the vertical direction according to their own shapes. For the smooth section 8 and the bent section 9, when processing the first protrusion 6 and the second protrusion 7, they need to be processed into a shape with the same appearance as the flat wire body 17 to facilitate the stamping and integrated molding of the flat wire body 17.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
