[0033] In order to better explain the present invention, and to facilitate understanding, the following Figure 1-4 , the utility model is described in detail through specific implementation methods. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 2 The orientation is used as a reference.

[0034] Embodiment 1:

[0035] Reference Figure 1-Figure 5 An embodiment of the utility model provides a high-voltage motor coil bending tool, including an extrusion assembly, the extrusion assembly including a fixed block 1 and a first extrusion block 2 that can slide vertically relative to the fixed block 1, the first extrusion block 2 can switch between a first disengagement position away from the fixed block 1 and a first forming position close to the fixed block 1; the high-voltage motor coil 3 can be detachably connected to a side of the fixed block 1 close to the first extrusion block 2, and the high-voltage motor coil 3 extends laterally toward the first extrusion block 2; when the first extrusion block 2 switches from the first disengagement position to the first forming position, the first extrusion block 2 can vertically load the high-voltage motor coil 3, so that the high-voltage motor coil 3 can gradually fit the opposite side walls of the first extrusion block 2 and the fixed block 1.

[0036] Specifically, according to Figure 2 The directions shown are: horizontal direction is left-right direction, and vertical direction is up-down direction. The horizontal and vertical directions of this patent are only reference directions, not absolute directions. A direction slightly deviating from this direction is also within the range of the horizontal and vertical directions specified by this patent.

[0037] In this embodiment, the bending tool includes an extrusion assembly, which can replace workers to bend the high-voltage motor coil 3. The fixed block 1 serves as the bending reference of the high-voltage motor coil 3. The high-voltage motor coil 3 is fixed on the fixed block 1. In the process of the first extrusion block 2 running from the first disengaged position to the first forming position, the first extrusion block 2 will first gradually approach the high-voltage motor coil 3 to bend the high-voltage motor coil 3. As the first extrusion block 2 continues to slide, the high-voltage motor coil 3 will eventually be squeezed between the fixed block 1 and the first extrusion block 2, and the shape of the side walls of the fixed block 1 and the first extrusion block 2 that are close to each other is determined, so the bending and forming of the high-voltage motor coil 3 can be achieved.

[0038] The present technical solution replaces the technical solution of manually forming the high-voltage motor coil 3 by striking the high-voltage motor coil 3 with a copper hammer in the tooling. Since the shapes of the first extrusion block 2 and the fixing block 1 are already fixed, the high-voltage motor coil 3 can be bent and formed by extruding the first extrusion block 2 in cooperation with the fixing block 1 without manual adjustment, which greatly improves the bending accuracy of the high-voltage motor coil 3, reduces the bending error of the high-voltage motor coil 3, and improves the bending consistency of the high-voltage motor coil 3.

[0039] By cooperating with a first extrusion block 2 and a fixing block 1, the high-voltage motor coil 3 can be bent. If the high-voltage motor coil 3 needs to be bent at multiple levels, the number of extrusion blocks needs to be increased. This embodiment takes the example that the high-voltage motor coil 3 needs to be bent twice.

[0040] The extrusion assembly also includes a second extrusion block 4 that can slide laterally relative to the fixed block 1. When the first extrusion block 2 is in the first forming position, the second extrusion block 4 can switch between a second forming position close to the first extrusion block 2 and a second disengaged position away from the first extrusion block 2; when the second extrusion block 4 switches from the second disengaged position to the second forming position, the second extrusion block 4 can laterally load the high-voltage motor coil 3, thereby enabling the high-voltage motor coil 3 to gradually fit the opposite side walls of the first extrusion block 2 and the second extrusion block 4.

[0041] In this embodiment, the extrusion assembly also includes a second extrusion block 4. When the first extrusion block 2 completes the bending operation of the high-voltage motor coil 3, the second extrusion block 4 can cooperate with the first extrusion block 2 and the fixed block 1 to achieve the re-bending of the high-voltage motor coil 3. The fixed block 1 and the first extrusion block 2 that does not move constitute the bending reference for the secondary bending of the high-voltage motor coil 3. In the process of the second extrusion block 4 running from the second disengaged position to the second forming position, the second extrusion block 4 will first gradually approach the high-voltage motor coil 3 and bend the high-voltage motor coil 3 again. As the second extrusion block 4 continues to slide, the high-voltage motor coil 3 will eventually be squeezed between the first extrusion block 2 and the second extrusion block 4, and the shape of the side walls of the first extrusion block 2 and the second extrusion block 4 that are close to each other is determined, so that the high-voltage motor coil 3 can be bent again.

[0042] In this embodiment, the fixing block 1 includes adjacent first fitting surfaces 11 and second fitting surfaces 12, and the high-voltage motor coil 3 is detachably connected to the first fitting surface 11; the first extrusion block 2 includes adjacent first extrusion surfaces 21 and second extrusion surfaces 22, the first extrusion surface 21 is parallel to the second fitting surface 12, and the first extrusion surface 21 and the second fitting surface 12 are side surfaces close to each other; when the first extrusion block 2 is in the disengaged position, the angle between the end of the first extrusion surface 21 away from the first extrusion block 2 and the vertical direction is α, where 0°≤α≤90°; the second extrusion block 4 includes adjacent third extrusion surfaces 41 and fourth extrusion surfaces 42. The third extrusion surface 41 is parallel to the second extrusion surface 22 and both extend laterally; the third extrusion surface 41 and the second extrusion surface 22 are side surfaces close to each other; when the first extrusion surface 21 and the second fitting surface 12 are close to each other, the first extrusion surface 21 can extrude the high-voltage motor coil 3 so that the middle part of the high-voltage motor coil 3 extends obliquely relative to the head part of the laterally extending high-voltage motor coil 3; when the third extrusion surface 41 and the second extrusion surface 22 are close to each other, the fourth extrusion surface 42 extrude the high-voltage motor coil 3 so that the tail part of the high-voltage motor coil 3 extends laterally, so as to process the high-voltage motor coil 3 of the desired shape.

[0043] The extrusion surface and the fitting surface play a forming role on the first extrusion block 2, the second extrusion block 4 and the fixed block 1. The first extrusion block 2, the second extrusion block 4 and the fixed block 1 are all arranged in a replaceable form, and different shapes of high-voltage motor coils 3 can be obtained by combining different inclination angles of the extrusion surface and the fitting surface.

[0044] Specifically, the first extrusion block 2, the fixed block 1 and the second extrusion block 4 can all be set to a right-angled trapezoid, and the waistline surface and top surface thereof are used to extrude the high-voltage motor coil 3; that is, the waistline of the first extrusion block 2 is the first extrusion surface 21, the top surface of the first extrusion block 2 is the second extrusion surface 22, the top surface of the second extrusion block 4 is the third extrusion surface 41, the waistline surface of the second extrusion block 4 is the fourth extrusion surface 42, the top surface of the fixed block 1 is the first fitting surface 11, and the waistline surface of the fixed block 1 is the second positioning surface.

[0045] By setting 0°≤α≤90°, it can be ensured that the first extrusion surface 21 can always deform the high-voltage motor coil 3 by loading the extended high-voltage motor coil 3, so as to ensure the reliability of the bending tool.

[0046] The extrusion assembly also includes a telescopic driving member 5, which can drive the first extrusion block 2 and the second extrusion block 4 to slide. Specifically, the telescopic driving member 5 is also configured as a hydraulic cylinder to obtain sufficient extrusion force, and the first extrusion position and the second extrusion position corresponding to the first extrusion block 2 and the second extrusion block 4 are both the limit positions when the telescopic driving member 5 is in operation. The working characteristics of the hydraulic cylinder itself are utilized to limit the limit positions of the operation of the first extrusion block 2 and the second extrusion block 4, without the need to set up an additional forming control system, thereby reducing the overall cost of the bending tooling.

[0047] In this embodiment, the high-voltage motor coil bending tool also includes a base plate 6, the fixed block 1 and the telescopic driving member 5 are both fixedly connected to the base plate 6, and the first extrusion block 2 and the second extrusion block 4 are both slidably connected to the base plate 6.

[0048] A square groove may be provided on the base plate 6 , and protrusions which are slidably matched with the square groove are provided on the first extrusion block 2 and the second extrusion block 4 .

[0049] The substrate 6 serves as a support body for the fixed block 1, the first extrusion block 2, the second extrusion block 4 and the telescopic driving member 5. The first extrusion block 2 and the second extrusion block 4 are both slidably connected to the substrate 6. Therefore, the sliding trajectory of the first extrusion block 2 and the second extrusion block 4 will be more precise, thereby improving the bending accuracy of the bending tooling.

[0050] At the same time, the above-mentioned components are all installed on a base plate 6, which can improve the modularity and integrity of the bending tool, and further help to improve the transportation flexibility and installation convenience of the bending tool.

[0051] Specifically, a process groove may be provided on the substrate 6 to reduce the curb weight of the bending tool.

[0052] Embodiment 2:

[0053] Reference Figure 2-5In addition to all the technical solutions of the above embodiments, the embodiments of the present utility model further have the following technical solutions:

[0054] Multiple groups of extrusion assemblies are arranged on the base plate 6; the first extrusion block 2 and / or the second extrusion block 4 in one group of extrusion assemblies can be linked with the first extrusion block 2 and / or the second extrusion block 4 in another group of extrusion assemblies.

[0055] In this embodiment, multiple groups of extrusion assemblies can simultaneously complete the bending processing of multiple high-voltage motor coils 3. The sliding directions of the first extrusion blocks 2 of different groups can be set to be consistent, and the sliding directions of the second extrusion blocks 4 of different groups can also be set to be consistent. Arranging the extrusion blocks with consistent sliding directions in a linked form can save a telescopic drive component 5, thereby reducing the cost of the bending tooling.

[0056] Specifically, a possible implementation form is to set two groups of extrusion assemblies on the substrate 6, and the extrusion assemblies are symmetrically arranged on the substrate 6, and the first extrusion blocks 2 in adjacent extrusion assemblies are connected as a whole. In this way, the two first extrusion blocks 2 formed as one can be operated in conjunction, and at the same time, they are driven by a telescopic drive member 5 to reduce the cost of the bending tooling.

The connection block 7 is detachably connected to the corresponding body. The first extrusion surface 21 , the fourth extrusion surface 42 and the second fitting surface 12 are all formed on the corresponding connection block 7 .

[0060] In this embodiment, the Figure 5 In the replacement form shown, the first extrusion block 2, the second extrusion block 4 and the fixed block 1 are set as a split structure, so that they all include a main body and a connecting block 7, and the corresponding parts forming the first extrusion surface 21, the fourth extrusion surface 42 and the second fitting surface 12 are made into a detachable connecting block 7. The detachable connection is achieved by bolts, and there is a smooth transition at the edge position of the connection between the connecting block 7 and the corresponding extrusion block and the fixed block 1. In this way, by replacing different types of connecting blocks 7, different types of high-voltage motor coils 3 can be processed.
