[0003] A traditional die head usually includes a die cover and two ear mounting blocks arranged in the die cover. A connecting piece is also arranged between the two ear mounting blocks. The connecting piece is provided with an ear push-pull rod for supporting the ear mounting blocks. When the connecting piece moves back and forth driven by the power component, the ear push-pull rod will support the matching inclined surface of the ear mounting block to make the ear mounting block slide up and down relative to the die cover.

[0004] Since the lug mounting block, the die cover and the lug push-pull rod all adopt a sliding fit, in order to ensure the accuracy of the lug opening adjustment, the mating surface of the die cover and the lug mounting block needs to go through multiple processing steps to reduce the roughness of the mating surface, which makes the manufacturing cost of the die head high, and the entire mating surface needs to be coated with grease or lubricating oil during maintenance, which makes the maintenance work cumbersome.

[0040] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment" or "in some embodiments" appear in various places throughout the specification, not all references are to the same embodiment. Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0041] See also Figures 1 to 5 As shown, the winding die head provided in the embodiment of the present application is now described. The winding die head comprises:

[0042] A mold cover 1, wherein a connecting through hole 12 is provided in the middle of the mold cover 1, and mounting block receiving grooves 11 are provided at the upper and lower parts of the mold cover 1, respectively, and ear mounting blocks 2 are provided in both of the mounting block receiving grooves 11;

[0043] A connecting member 3, on which a lug push-pull block 4 is disposed, and a matching inclined surface 21 is disposed on the lug mounting block 2 or the lug push-pull block 4. When the connecting member 3 drives the lug push-pull block 4 to reciprocate, the matching inclined surface 21 is subjected to force to make the lug mounting blocks 2 move closer to or farther from each other;

[0044] An elastic member, one end of which acts on the ear mounting block 2, and the other end of which acts on a fixing member, and the elastic member applies a force to the ear mounting block 2 to move it closer to the ear push-pull block 4;

[0045] A linear guide rail 5 is longitudinally arranged between the lug mounting block 2 and the mounting block receiving groove 11 . When relative movement occurs between the lug mounting block 2 and the mounting block receiving groove 11 , the lug mounting block 2 moves along the linear guide rail 5 .

[0046] In the existing stator winding die head, there are multiple contact surfaces between the lug mounting block 2 and the mold cover 1. As the winding proceeds, the two lug mounting blocks 2 need to move away from or closer to each other, and it is necessary to ensure that the distance of a single adjustment is the distance of a wire diameter, which is a very high precision requirement. This means that the fitting clearance between the lug mounting block 2 and the mold cover 1 cannot be too large. If the fit is too large, it will cause a large error and the distance of a single adjustment cannot be accurately controlled. It also cannot be too small, because if it is too small, the combination between the two will be too tight, resulting in obstruction of the movement of the lug mounting block 2 in the mold cover 1; this requires higher processing accuracy for the dimensional processing of the mold cover 1 and the lug mounting block 2, and higher processing accuracy means higher manufacturing costs.

[0047] Furthermore, since the ear mounting block 2 needs to slide up and down relative to the mold cover 1, and the sliding distance also needs to be precisely controlled, the mating surfaces of the two must be smooth enough, that is, the surface roughness of the mating surfaces must be low enough; similarly, low surface roughness also means high processing quality and cumbersome processing steps, which further leads to the high production and manufacturing costs of existing stator winding die heads.

[0048] In order to overcome the above problems of the prior art, the present application provides a winding die head, such as Figures 1 to 3 As shown, it includes a mold cover 1, and a mounting block receiving groove 11 is respectively arranged at the upper part and the lower part of the mold cover 1, and a lug mounting block 2 is arranged in each of the two mounting block receiving grooves 11; in this embodiment, a longitudinal linear guide rail 5 is arranged between the lug mounting block 2 and the mounting block receiving groove 11, and the sliding of the lug mounting block 2 relative to the mounting block receiving groove 11 is realized by means of the linear guide rail 5, and the lug mounting block 2 and the mounting block receiving groove 11 are not in direct contact, so there is no need to process the surfaces of the mounting block receiving groove 11 and the lug mounting block 2 through a complex and high-cost process, which effectively reduces the production and manufacturing cost of the winding die head.

[0049] Furthermore, in this embodiment, since the lug mounting block 2 and the mounting block receiving groove 11 do not contact each other, the dimensional accuracy requirements of the two parts are relatively low, further reducing the production cost of the winding die head. In order to ensure the smooth movement of the lug mounting block 2 relative to the die cover 1, the number of linear guide rails 5 can be multiple and evenly distributed inside the mounting block receiving groove 11.

[0050] The die cover 1 of the winding die head of this embodiment is also provided with a connecting through hole 12, and the connecting member 3 is connected to the reciprocating power device through the connecting through hole 12. The power device can be a pneumatic rod or an electric rod. The shape of the connecting member 3 itself is not limited in this application, and can be cylindrical, prismatic, or other shapes. The connecting member 3 is provided with a lug push-pull block 4, and the lug mounting block 2 and / or the lug push-pull block 4 are provided with a matching inclined surface 21. When the connecting member 3 drives the lug push-pull block 4 to reciprocate, the matching inclined surface 21 is subjected to force to make the lug mounting blocks 2 move closer to or farther from each other.

[0051] According to an example of this application, Figure 4 As shown, this figure is only a schematic diagram for explanation. When a matching inclined surface 21 is set on the ear mounting block 2, when the connecting member 3 reciprocates, the ear push-pull block 4 supports the matching inclined surface 21 to make the ear mounting block 2 rise or fall.

[0052] According to an example of this application, Figure 5 As shown, this figure is only a schematic diagram for explanation. When a matching inclined surface 21 is set on the support ear push-pull block 4, when the connecting member 3 reciprocates, the matching inclined surface 21 on the support ear push-pull block 4 supports the support ear mounting block 2, causing the support ear mounting block 2 to rise or fall.

[0053] The winding die head of this embodiment also includes an elastic member, one end of which acts on the lug mounting block 2, and the other end acts on a fixing member, so as to apply a force to the lug mounting block 2 to approach the lug push-pull block 4. When the two lug mounting blocks 2 move away from each other, the elastic member accumulates elastic potential energy, and when the two lug mounting blocks 2 move close to each other, the elastic member releases the elastic potential energy.

[0054] According to one embodiment of the present invention, Figures 1 to 3 As shown, the fixing member is a fixing plate 6, which is arranged at the upper and lower ends of the mold cover 1, and the elastic member is a compression spring 8, one end of which is supported on the ear mounting block 2, and the other end is supported on the fixing plate 6.

[0055] In this embodiment, the fixing member is a fixing plate 6 arranged at the upper and lower ends of the mold cover 1, and the elastic member is a compression spring 8. The elastic force of the compression spring 8 pushes the ear mounting block 2 in the direction close to the ear push-pull block 4, so that it is supported on the ear push-pull block 4. When the connecting member 3 reciprocates to make the ear push-pull block 4 support the ear mounting block 2, the ear mounting blocks 2 move away from each other, and the compression spring 8 is gradually compressed to accumulate elastic potential energy; when the connecting member 3 reciprocates to unload the thrust applied by the ear push-pull block 4 to the ear mounting block 2, the compression spring 8 gradually releases the elastic potential energy, so that the ear mounting block 2 moves in the direction close to the ear push-pull block 4, and then the two ear mounting blocks 2 move closer to each other. It should be noted that the ear mounting block 2 is used to install the winding ear, and the ear is not shown in this application.

[0056] By providing the compression spring 8 and the fixing plate 6, the lug mounting block 2 is in a state of being stressed at both ends during the entire movement process, thereby ensuring the accuracy of its position adjustment and improving the winding accuracy when the winding die head is used for winding.

[0057] Further, in this embodiment, if Figure 3 As shown, the surface of the ear mounting block 2 facing the fixed plate 6 is provided with a plurality of compression spring mounting holes 22, and a compression spring 8 is provided in each of the plurality of compression spring mounting holes 22. In order to ensure that the ear mounting block 2 is subjected to uniform force and facilitate the positioning and installation of the compression spring 8, in this embodiment, the surface of the ear mounting block 2 facing the fixed plate 6 is provided with a plurality of compression spring mounting holes 22, such as Figure 3 As shown, a compression spring 8 is disposed in each compression spring mounting hole 22 distributed at the four corners of the surface of the ear mounting block 2 .

[0058] According to one embodiment of the present application, the linear guide rail 5 between the ear mounting block 2 and the mounting block receiving groove 11 is a cross roller guide rail, and the cross roller guide rail includes a first guide rail 51 fixed to the mounting block receiving groove 11 and a second guide rail 52 fixed to the ear mounting block 2, and a ball is arranged between the first guide rail 51 and the second guide rail 52.

[0059] In order to reduce the manufacturing cost of the stator winding die head, in this embodiment, the linear guide rail 5 between the ear mounting block 2 and the mounting block receiving groove 11 is a cross roller guide rail. The cross roller rail is a standard part with relatively low procurement cost, and the gap of the cross roller guide rail is adjustable, which can compensate for the dimensional error caused by the processing of the mold cover 1 and the ear mounting block 2. Therefore, even if the mold cover 1 and the ear mounting block 2 adopt a relatively low-cost rough processing process, the existing error can be corrected by the cross roller guide rail, which reduces the manufacturing cost of the winding die head while meeting the use accuracy requirements of the winding die head. Furthermore, when the cross roller guide rail is maintained, it only needs to drip lubricating oil along the guide rail direction. Compared with the method in which the ear mounting block 2 directly contacts the mold cover 1, the maintenance work is simpler.

[0060] According to one embodiment of the present application, Figures 1 to 3 As shown, a guide sleeve 7 cooperating with the connecting piece 3 is provided at the connecting through hole 12 in the middle of the mold cover 1. The guide sleeve 7 is arranged on the outer surface of the connecting piece 3. A guide groove 71 matching the support ear push-pull block 4 is opened on the guide sleeve 7, and the support ear push-pull block 4 passes through the guide groove 71.

[0061] To ensure the smooth movement of the connecting member 3, a guide sleeve 7 is further provided in the mold cover 1 in this embodiment. The guide sleeve 7 is arranged in the connecting through hole 12 in an interference fit manner, and the cross roller guide passes through the guide sleeve 7 in the vertical direction.

[0062] The guide sleeve 7 is provided with a guide groove 71, which is closed at both ends in the horizontal direction in this embodiment, and the ear push-pull block 4 is confined therein to restrict the limit travel of the ear push-pull block 4. In this embodiment, the guide sleeve 7 is provided to make the movement of the connector 3 more stable.

[0063] According to one embodiment of the present application, Figure 6 As shown, this figure is only an illustrative diagram. The fixing member is a fixing protrusion arranged in the middle of the mold cover 1 and fixedly connected to the mold cover 1. The elastic member is a tension spring 9. One end of the tension spring 9 tightly pulls the support ear mounting block 2, and the other end tightly pulls the fixing protrusion.

[0064] In this embodiment, the fixing member is a fixing protrusion, which is relatively fixed to the mold cover 1, and the elastic member is a tension spring 9, the elastic force of which pulls the lug mounting block 2 toward the direction close to the lug push-pull block 4, so that it is supported on the lug push-pull block 4. When the connecting member 3 reciprocates to make the lug push-pull block 4 support the lug mounting block 2, the lug mounting blocks 2 move away from each other, and at this time, the tension spring 9 is gradually stretched to accumulate elastic potential energy; when the connecting member 3 reciprocates to unload the thrust applied by the lug push-pull block 4 to the lug mounting block 2, the tension spring 9 gradually releases the elastic potential energy, so that the lug mounting block 2 moves toward the direction close to the lug push-pull block 4, and then the two lug mounting blocks 2 move closer to each other.

[0065] The technical solution of using the tension spring 9 in this embodiment and the technical solution of using the compression spring 8 mentioned above can both ensure that the support ear mounting block 2 is in a state of being stressed at both ends during the entire movement process, thereby ensuring the accuracy of its position adjustment and improving the accuracy of winding when using this winding die head.

[0066] According to one embodiment of the present application, Figure 7 and Figure 8 As shown, the winding die head of the present application may also include a winding die connecting plate 10 and a connecting rod 101 connecting the winding die connecting plate 10 and the die cover 1; the die cover 1 is provided with a guide hole 107 for the connecting rod 101 to pass through, the connecting rod 101 passes through the guide hole 107, one end of the connecting rod 101 is connected to the winding die connecting plate 10, and the other end is provided with a stop block 102; a resist spring 106 is also provided between the winding die connecting plate 10 and the die cover 1.

[0067] In certain stator winding environments with special requirements, in addition to the winding die head, an auxiliary winding mold is also needed. The auxiliary winding mold needs to be combined with the stator core and is usually arranged on the side of the winding die head facing the stator to be wound. Therefore, the winding die head of the present application can also include a winding mold connecting plate 10, which is used to connect to the auxiliary winding mold (not shown in the figure).

[0068] like Figure 7 and Figure 8 As shown, the winding mold connecting plate 10 is connected to the mold cover 1 through a connecting rod 101. The connecting rod 101 is inserted into a guide through hole 107 on the mold cover 1 to provide a guide for the movement of the winding mold connecting plate 10. In addition, since the auxiliary winding mold needs to press against the outer surface of the stator core when combined with the stator core, in this embodiment, a pressing spring 106 is further provided between the winding mold connecting plate 10 and the mold cover 1. The elastic force of the pressing spring 106 pushes the winding mold connecting plate 10 to the side away from the mold cover 1.

[0069] According to an embodiment of the present application, the number of the push-up springs 106 is two, and they are symmetrically arranged on both sides of the mold cover 1. Figure 8 As shown, two supporting springs 106 are symmetrically arranged on one side of the mold cover 1 facing the winding mold connecting plate 10, one on the left and one on the right, to ensure the uniformity of the applied elastic force.

[0070] According to one embodiment of the present application, a slide rail 103 is also fixed on the winding die connecting plate 10, and a slider 104 matching the slide rail 103 is provided on the die cover 1. Similarly, when only the connecting rod 101 is relied upon to provide a guiding function for the winding die connecting plate 10, the outer surface of the connecting rod 101 and the inner surface of the guiding through hole 107 need a relatively low surface roughness to ensure the smooth movement of the winding die connecting plate 10, which will result in a higher production cost.

[0071] In this embodiment, the guide of the winding mold connecting plate 10 is mainly performed through the cooperation of the slide rail 103 and the slider 104, and the connecting rod 101 only plays an auxiliary guiding role. In this way, the smooth movement of the winding mold connecting plate 10 can be ensured while reducing the roughness of the outer surface of the connecting rod 101 and the inner surface of the guide through hole 107, thereby reducing the production cost.

[0072] In this embodiment, a slider mounting plate 105 is further provided on the mold cover 1, and the slider mounting plate 105 is detachably connected to the outer surface of the mold cover 1, and the slider 104 is fixed between the module fixing plate 6 and the outer surface of the mold cover 1. In this way, the installation, maintenance and replacement of the slider 104 and the slide rail 103 are facilitated.

[0073] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0074] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
