In the process of flat wire motor assembly, since the electronic copper wire winding is a flat thick copper wire, the stator wire package cannot be formed by winding like round copper wire. The flat copper wire must be processed one by one at a time. After being formed into a hairpin, the hairpin wire is inserted into the stator core, and then through subsequent expansion, twisting, welding, varnishing and other equipment, the finished motor stator is finally formed.

Therefore, the directional words used are used to illustrate rather than limit the invention.

[0043] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0044] Embodiment: A forming device for issuing cards for new energy flat wire motors, see attached Figure 1 -Attached Figure 8, including a first forming mechanism 1, a second forming mechanism 2 and a third forming mechanism 3, wherein the first forming mechanism 1 is used to fold the flat copper wire into a U-shaped copper wire; the second forming mechanism 2 is used to form a Z-shaped structure at the end of the U-shaped copper wire; the third forming mechanism 3 is used to perform 3D bending on the end of the U-shaped copper wire.

[0045] When the flat copper wire is being formed, the operator sequentially feeds the flat copper wire into the first forming mechanism 1, the second forming mechanism 2 and the third forming mechanism 3. The three forming mechanisms deform the flat copper wire three times at a time, without manual forming, thereby improving the forming efficiency and accuracy.

[0046] Specifically, the first forming mechanism 1 includes a positioning component 11 and a forming component 12, wherein the positioning component 11 is used to clamp the flat copper wire and position one end of the flat copper wire; the forming component 12 is used to bend the flat copper wire positioned and clamped by the positioning component 11 into a U-shaped copper wire. The forming component 12 includes a bending plate 124, a rotating seat 127, and a folding line shaft 121, wherein one end of the bending plate 124 is formed with a forming surface matching the shape of the bending part of the U-shaped copper wire; the rotating seat 127 rotates around a vertical axis; the folding line shaft 121 is rotatably connected to the rotating seat 127 and the rotating axis is vertical, and the axis of the folding line shaft 121 is located on one side of the rotating axis of the rotating seat 127 so that when the rotating seat 127 rotates, the folding line shaft 121 pushes the flat copper wire to be folded into a U-shaped copper wire.

[0047] When the flat copper wire is folded into a U shape, the positioning assembly 11 is used to clamp the flat copper wire and position one end of the flat copper wire. At this time, the folding position of the flat copper wire is located at the forming surface of the bending plate 124. Then, the rotating seat 127 rotates, and the folding line shaft 121 on the rotating shaft pushes the flat copper wire to fold into a U shape around the forming surface of the bending plate 124. The folding line shaft 121 is arranged to be rotatably connected to the rotating seat 127, so that when the folding line shaft 121 contacts the flat copper wire, no friction occurs, and it is not easy to wear the surface of the flat copper wire.

[0048] Specifically, a positioning groove 1241 penetrating the bending plate 124 along the length direction of the flat copper wire is provided at the top of the bending plate 124 , and the forming surface is located on the side of the positioning groove 1241 facing the bending direction of the flat copper wire.

[0049] Specifically, the positioning assembly 11 includes a clamping block 111 and a reference block 112. The clamping blocks 111 are provided with two and the two clamping blocks 111 can approach each other and interlock with each other in the horizontal direction to achieve clamping and loosening of the flat copper wire from both sides; the reference block 112 is located on the side of the two clamping blocks 111 away from the forming assembly 12, and the reference block 112 is used to position the end of the flat copper wire. When clamping and positioning the flat copper wire, the two clamping blocks 111 are approached to each other to achieve clamping of the flat copper wire, and because the position of the reference block 112 is fixed, one end of the flat copper wire is pressed against the side of the reference block 112 close to the bending plate 124, so that the bending part of the flat copper wire can be accurately aligned with the forming surface.

[0050] Specifically, the positioning assembly 11 also includes a wire clamping cylinder and a telescopic power piece.

The wire clamping cylinder is configured as a double-claw cylinder, so that the two clamping claws can drive the two clamping blocks 111 to slide toward or away from each other at a constant speed, so that the flat copper wire can be inserted into the positioning groove 1241 of the bending plate 124 after being clamped. By setting the telescopic power piece, the position of the reference block 112 can be adjusted according to different flat copper wires, so that flat copper wires of different lengths can be bent.

[0051] Specifically, the forming assembly 12 also includes a forming seat 122, a fixed support 126 and a sliding seat 128.

[0052] By setting the sliding seat 128, when the flat copper wire is fixed on the positioning assembly 11, the rotating seat 127 and the folding line shaft 121 can move downward to prevent the fixing of the flat copper wire from being blocked. After the flat copper wire is fixed, the sliding seat 128 drives the rotating seat 127 and the folding line shaft 121 to move upward to achieve the bending of the flat copper wire. The sliding seat 128 is driven by the linear module to slide up and down on the fixed support 126.

[0053] Specifically, the forming assembly 12 also includes a wire pressing plate 125 and a wire supporting plate 123.

[0056] The forming die 22 with different heights at the two combined dies can be bent into a Z-shape at the end of the U-shaped copper wire, that is, the connecting section between the two wire legs of the U-shaped copper wire. Specifically, the two die fingers 21 are driven to move by a double-claw cylinder and the two die fingers 21 are respectively fixedly connected to the two clamping jaws of the double-claw cylinder.

[0057] Specifically, the second molding mechanism 2 further includes a positioning seat 23 and a reference plate 24.
