Description

Technical Field

[0001] The utility model relates to the technical field of stator processing, and particularly relates to a shaping device. Background Art

[0002] A stator shaping machine is a device used for shaping stator coils. Most of the existing shaping machines are single-type shaping machines, which can only shape one type of stator.

[0003] For example, the utility model patent with the patent number "201420430915.1" and the name "A motor stator shaping machine" discloses a stator shaping machine. This stator shaping machine can only shape one type of stator. If you want to shape different stators, you need to replace all the matching shaping molds. Although the new stator can be shaped after replacement, if you want to shape the original stator again, you need to change back to the original mold. That is to say, when the user has two different stator products that need to be shaped, the mold needs to be replaced before use. This process is time-consuming and laborious, and is not conducive to production efficiency. Summary of the Utility Model

[0004] In order to solve the technical problem that most of the existing stator shaping machines are single-type, and it is time-consuming, laborious and has low production efficiency to replace the mold when shaping different stator cores, the utility model provides a shaping device. The device integrates two shaping devices, and each shaping device is set corresponding to different stator specifications. The stator corresponding to two specifications can be directly shaped, and the production and processing are more convenient.

[0005] The technical solution of the utility model is as follows:

[0006] A shaping device includes a first shaping device and a second shaping device which are integrally arranged. The first shaping device and the second shaping device are set corresponding to two different specifications of stators.

The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0033] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

Therefore, they should not be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0035] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, these words have no special meaning. Therefore, they should not be construed as limiting the protection scope of the present invention.

[0036] As Figure 1-12 shown, this embodiment provides a shaping device 100 capable of shaping a stator 103. The shaping device 100 includes an integrally arranged first shaping device 101 and a second shaping device 102. The first shaping device 101 and the second shaping device 102 are set corresponding to two different specifications of the stator 103. For example, the two stators 103 have different lengths or inner and outer diameters, etc. When shaping is required, the stator 103 to be shaped is shaped by the first shaping device 101 or the second shaping device 102.

[0037] The shaping device 100 of this embodiment can meet the user's need to shape two different stator products. When the first stator 103 needs to be shaped, the user can use the first shaping device 101 for shaping. When the second stator 103 needs to be shaped, the user can use the second shaping device 102 for shaping, without the need to replace the corresponding molds, making production and processing more convenient. Moreover, the shaping device 100 of this embodiment is different from two separate shaping machines. Instead, the first shaping device 101 and the second shaping device 102 are integrally arranged, that is, they share some components as much as possible, including but not limited to the control component 4, the protective cover 1, the oil collecting tray 3, the bottom plate 2 for installation, etc., forming a shaping device 100. Only one of the shaping devices works each time, which can reduce the occupied space to a certain extent and save certain costs.

[0038] As Figure 2-4 shown, the shaping device 100 of this embodiment further includes a protective cover 1. The first shaping device 101 and the second shaping device 102 share this protective cover 1, which can save space and costs. The protective cover 1 is of a frame structure and covers the outer periphery of the first shaping device 101 and the second shaping device 102, but the front space needs to be vacated for operations such as manual loading and unloading and button control.

[0039] Furthermore, the first shaping device 101 and the second shaping device 102 of this embodiment are installed on the same bottom plate 2, that is, they share a bottom plate 2. The bottom plate 2 can be directly milled from a large board, which can save a certain amount of space and costs. Multiple support mounting plates 21 extend outward from the bottom of the left, right, and rear sides of the bottom plate 2 towards the protective cover 1, and bolts are screwed in from the bottom of these support mounting plates 21 for installation and connection, thereby fixing and supporting the protective cover 1. Preferably, the support mounting plates 21 do not protrude from the outer side surface of the protective cover 1. This hidden design makes the overall shape more beautiful.

[0040] As Figure 1-2 shown, the shaping device 100 further includes an oil collecting tray 3. The oil collecting tray 3 is arranged at the bottom of the bottom plate 2 of the first shaping device 101 and the second shaping device 102 for collecting oil, waste liquid, etc.

[0041] In addition, as Figure 5As shown in the figure, the shaping device 100 further includes a control component 4. The control component 4 is arranged at the rear side and is distributed vertically. The control component 4 includes, but is not limited to, a hydraulic station 41, an electrical box 42, and a display screen 43 for controlling the operation of each shaping device. The first shaping device 101 and the second shaping device 102 share this control component 4, which can save a certain amount of space and cost. Compared with using two separate shaping machines in this embodiment, in terms of the hydraulic station 41, although the same number of valve groups and pipelines are required, a fuel tank, an oil pump motor, and a fan can be shared; in terms of the electrical box 42, although the same number of sensors and cables are required, a box body and a controller can be shared; in terms of the display screen 43, a display screen 43 can also be shared for display.

[0042] As Figure 6-12 shown in the figure, the first shaping device 101 and the second shaping device 102 in this embodiment both include a flipping mechanism 5, a loading and unloading mechanism 6, an upper shaping mechanism 71, a lower shaping mechanism 72, etc., but are respectively set for stators 103 of corresponding specifications. Only the structure of one of the shaping devices will be introduced as an example below.

[0043] Among them, the flipping mechanism 5 includes a flipping plate 51, a sliding seat 54, an arc-shaped guiding plate 55, and a driving module 56. Both sides of the flipping plate 51 are rotatably connected to the sliding seat 54. The sliding seat 54 is U-shaped, with the left and right sides slidingly arranged by means of sliders, and the middle part is connected to the driving end of the driving module 56. The driving module 56 is preferably a hydraulic cylinder, which can drive the flipping plate 51 to move back and forth together through the sliding seat 54. When the flipping plate 51 moves back and forth, it cooperates with the arc-shaped guiding plates 55 fixedly arranged on both sides to achieve flipping. When moving forward, it flips from horizontal to vertical, and when moving backward, it flips from vertical to horizontal.

[0044] Furthermore, the flipping mechanism 5 further includes a lower tooth protection component 52 and a support and positioning component 53. The lower tooth protection component 52 is arranged on the flipping plate 51, and the support and positioning component 53 is arranged on the lower tooth protection component 52. The lower tooth protection component 52 includes a movable disk 522 and a plurality of circumferentially arranged tooth protectors 521. Since the tooth protectors 521 are limited to radial movement only, when the movable disk 522 is driven to rotate, it can drive each tooth protector 521 to radially extend or retract. The support and positioning component 53 includes a support rod 531 and a rotation limiting member 532. The support rod 531 is used for auxiliary support when the stator 103 is flipped, and its length can be set according to the specification of the stator 103; the rotation limiting member 532 is used to cooperate with the groove on the outer wall of the stator 103 to limit the circumferential rotation of the stator 103.

[0045] In the initial state, the sliding seat 54 moves forward away from the shaping position under the action of the driving module 56. The flipping plate 51 is located on the front side of the shaping position and is in a vertical state under the action of the arc-shaped guide plate 55, and can receive the lateral stator 103. After the stator 103 is fed in a lateral state, it is assisted in supporting and circumferentially positioned by the support and positioning assembly 53. When shaping is required, the driving module 56 drives the sliding seat 54 to move backward towards the shaping position. The flipping plate 51 is flipped from a vertical state to a horizontal state under the action of the arc-shaped guide plate 55, and is assisted in supporting during the flipping process by the support rod 531. After flipping, the stator 103 is in a vertical state.

[0046] Among them, the loading and unloading mechanism 6 includes a moving seat 61. The moving seat 61 is arranged on the front side of the flipping mechanism 5. The bottom of the moving seat 61 is provided with a slide rail and a slider. A plurality of horizontally arranged carrying rollers 611 are provided on the moving seat 61, which can correspondingly carry the lateral stator 103. When loading, the stator 103 is horizontally placed on the moving seat 61 and carried by the carrying rollers 611. The operator manually pushes the moving seat 61 towards the tooth protection 521 assembly so that the stator 103 is connected with the lower tooth protection assembly 52 for loading. When unloading, the stator 103 is flipped to the lateral by the flipping mechanism 5 and carried by the carrying rollers 611, and the moving seat 61 is manually pulled away from the lower tooth protection assembly 52 for unloading.

[0047] Among them, the upper shaping mechanism 71 includes an upper shaping die 711, a die core 712, and an upper tooth protection assembly 713, which are driven to move up and down by an upper driving module 715. The upper driving module 715 is preferably a hydraulic cylinder. An upper spring 714 is further provided between the upper shaping die 711, the die core 712, the upper tooth protection assembly 713 and the upper moving plate directly connected to the upper driving module 715. The lower shaping mechanism 72 includes a lower shaping die 721, which is driven to move up and down by a lower driving module 723. The lower driving module 723 is preferably a hydraulic cylinder. A lower spring 722 is further provided between the lower shaping die 721 and the lower moving plate directly connected to the lower driving module 723. When shaping, the upper driving module 715 first drives the upper shaping die 711, the die core 712, the upper tooth protection assembly 713 and the upper spring 714 to move downward to a set position, so that the upper tooth protection assembly 713 moves to a suitable height corresponding to the current stator 103 and can extend its tooth protection 521. The lower driving module 723 first drives the lower shaping die 721 and the lower spring 722 to move upward to a set position. Then, the upper driving module 715 moves downward for the second time, and the lower driving module 723 moves upward for the second time, compressing the upper spring 714 and the lower spring 722, and providing a shaping force by the upper spring 714 and the lower spring 722 for shaping.

[0048] In this embodiment, the first shaping device 101 / second shaping device 102 is provided with a lower dental guard driving mechanism 81 corresponding to the lower dental guard assembly 52 and an upper dental guard driving mechanism 82 corresponding to the upper dental guard assembly 713. When the lower dental guard assembly 52 is flipped in place and the upper dental guard assembly 713 moves in place, the lower dental guard driving mechanism 81 pushes to make the dental guard 521 in the lower dental guard assembly 52 extend, and the upper dental guard driving mechanism 82 pushes to make the dental guard 521 in the upper dental guard assembly 713 extend.

[0049] Specifically, as Figure 8 shown, the lower dental guard driving mechanism 81 includes a lower driving cylinder 811 and a four-bar linkage mechanism 812. The four-bar linkage mechanism 812 includes two vertical rods and two horizontal rods. One of the vertical rods and two horizontal rods on the left can rotate around the other fixed vertical rod on the right; the tail of the lower driving cylinder 811 is hinged to a fixed seat 813, and its head is hinged to the movable vertical rod on the left in the four-bar linkage mechanism 812. A pushing portion 8121 is provided on this vertical rod, and the pushing portion 8121 can cooperate with the bayonet 523 extended from the movable disk 522 in the lower dental guard assembly 52 to make its dental guard 521 extend and retract; in this embodiment, a cylinder is used for driving. Compared with the prior art using a swing cylinder, the cost is greatly reduced, and the movement is more stable through the four-bar linkage mechanism 812.

[0050] Further, as Figure 11 shown, the upper dental guard driving mechanism 82 includes an upper driving cylinder 821. The tail of the upper driving cylinder 821 is hinged to a fixed plate 822 in the upper shaping mechanism 71, and its head is hinged to the extended portion 7131 of the movable disk 522 in the upper dental guard assembly 713. When the upper driving cylinder 821 acts, it can realize the extension and retraction of the dental guard 521 in the upper dental guard assembly 713 through the extended portion 7131. In this way, using a cylinder for driving, compared with the prior art using a swing cylinder, the cost is greatly reduced.

[0051] When the shaping device 100 is in use, first, a corresponding shaping device is selected according to the specifications of the stator 103, and the stator 103 is pushed into the feeding position through the moving seat 61 of the loading and unloading mechanism 6; then, the start button on the front side is pressed to start working. A grating assembly is provided at the front edge of the protective cover 1 to detect whether the operator is still loading. After confirming safety, the flipping mechanism 5 drives the horizontal stator 103 to flip into a vertical position to the shaping position; then, the upper shaping die 711, the die core 712, and the lower tooth protection component 52 in the upper shaping mechanism 71 move downward under the drive of the upper drive module 715, so that the upper tooth protection component 713 moves to a suitable height position, and the lower shaping die 721 is also driven by the lower drive module 723 to a set height position, and the tooth protection actions are performed by the upper tooth protection drive mechanism 82 and the lower tooth protection drive mechanism 81; then, the upper drive module 715 moves downward for the second time, and the lower drive module 723 moves upward for the second time. The upper spring 714 and the lower spring 722 are compressed to provide shaping force for shaping; after shaping is completed, each tooth protection 521 retracts, the upper shaping mechanism 71 and the lower shaping mechanism 72 return to their original positions, and the stator 103 is flipped into a horizontal position onto the moving seat 61 of the loading and unloading mechanism 6 under the action of the flipping mechanism 5. The operator can pull out the moving seat 61 forward to unload the material.

[0052] As can be seen from the above, a shaping device provided in this embodiment is integrally provided with a first shaping device and a second shaping device, which can meet the needs of users for shaping two different stator products. There is no need to replace the corresponding molds during shaping, the production and processing are more convenient, and the overall size is small and the cost is low.

[0053] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
