Description

Technical Field

[0001] The utility model relates to the technical field of motor production, in particular to a bending die flipping device. Background Art

[0002] In the manufacturing process of the stator winding of a disc motor, the selection of the winding process directly affects the geometric shape and assembly quality of the stator. With the development of continuous winding technology, especially the application of the forward and reverse winding methods, higher requirements are put forward for the process compatibility and flexibility of winding equipment.

[0003] As Figure 1 shown, during the bending process, the straight continuously conveyed wire 2000 is continuously bent by the bending die at the required angle when passing through the bending die, and accumulates successively along the axial direction of the bending die to complete the bending and winding of the coil 600. If it is assumed that the winding direction of the coil 600 shown in the figure is the forward direction, then by changing the bending direction of the bending die, the reversely wound coil 600 can be obtained.

In order to be compatible with the forward and reverse winding of the coil 600, two different bending dies are required, and the bending die is often fixedly installed on the equipment. Therefore, it is necessary to replace the bending die or use different equipment to be compatible with different process requirements. This not only increases the complexity and cost of the equipment, but also increases the downtime and reduces the production efficiency during the process of replacing the bending die.

[0005] Therefore, it is urgent to invent a bending die flipping device to solve the above problems. Content of the Utility Model

[0045] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0046] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0047] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0048] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left", and "right" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0049] Such as Figure 1As shown, during the bending process, the straight and continuously conveyed wire 2000 is continuously bent by the bending die by the required angle when passing through the bending die, and is sequentially accumulated along the axial direction of the bending die to complete the bending and winding of the coil 600. If it is assumed that Figure 1 the winding direction of the coil 600 shown in is the positive direction, then by changing the bending direction of the bending die, a coil 600 with reverse winding can be obtained.

[0050] However, due to the structural characteristics of the stator winding of the disc motor, the bending direction of the bending die is fixed. In order to be compatible with the forward and reverse winding of the coil 600, two different bending dies are required, and the bending die is often fixedly installed on the equipment. Therefore, it is necessary to replace the bending die or use different equipment to be compatible with different process requirements. This not only increases the complexity and cost of the equipment, but also increases the downtime and reduces the production efficiency during the process of replacing the bending die.

[0051] To solve the above problems, as Figure 2 and Figure 3 shown, this embodiment provides a bending die flipping device. The bending die flipping device includes a driving component 100, a mounting table 200, and a frame 300. Among them, the driving component 100 is arranged on the frame 300, the mounting table 200 is connected to the output end of the driving component 100, the mounting table 200 is used for mounting the bending die, and the driving component 100 can drive the mounting table 200 to rotate around a preset axis so that the bending die on the mounting table 200 switches between a first state and a second state, and the bending direction of the bending die on the wire 2000 in the first state is opposite to the bending direction of the bending die on the wire 2000 in the second state.

[0052] The bending die flipping device realizes the support and fixation of the driving component 100 by installing the driving component 100 on the frame 300. By connecting the mounting table 200 for mounting the bending die to the output end of the driving component 100 and driving the mounting table 200 to rotate around a preset axis by the driving component 100, the effect of switching the bending die on the mounting table 200 between a first state and a second state by the driving component 100 is realized, so that the bending direction of the bending die on the wire 2000 in the first state is opposite to the bending direction of the bending die on the wire 2000 in the second state. When the bending die on the mounting table 200 is in the first state, the wire 2000 is sequentially bent into a coil 600 by the bending die in the positive direction. When the driving component 100 drives the bending die on the mounting table 200 to switch from the first state to the second state, the wire 2000 is bent into a coil 600 by the bending die in the reverse direction, realizing the forward and reverse winding of the coil 600 on the bending die without changing the bending die, ensuring that the winding directions of two adjacent coils 600 are opposite, and improving the working efficiency.

[0053] In this embodiment, the bending die in the first state and the bending die in the second state are deflected by 180° around a preset axis. Specifically, as Figure 3 shown, when the bending die bends the wire 2000 forward, the wire 2000 moves upward along the up-down direction; when the bending die bends the wire 2000 backward, the wire 2000 moves downward along the up-down direction. When it is necessary to wind the wire 2000 into five coils 600 in sequence from left to right, for the first coil 600 from left to right, the bending die on the mounting table 200 is in the first state, and the bending die bends the wire 2000 forward. Then, the driving assembly 100 drives the mounting table 200 to switch to the second state, the up-down direction of the bending die is reversed, and the bending die bends the wire 2000 backward. Since the up-down direction of the bending die is reversed, when the bending die is adjusted back to the first state, the wire 2000 on the second coil 600 from left to right becomes moving downward along the up-down direction, making the winding directions of the wire 2000 on the first coil 600 and the second coil 600 from left to right opposite. By analogy, the continuous winding of the wire 2000 on the five bending dies is completed in sequence from left to right. It should be noted that the specific winding steps and winding principle of the winding device both belong to the prior art and will not be elaborated here.

[0054] In addition, in this embodiment, the preset axis is the perpendicular line of the axial midpoint of the bending die. By setting the preset axis as the perpendicular line of the axial midpoint of the bending die, since the output position of the wire 2000 remains unchanged, the input port of the bending die in the first state is facing the wire 2000, and the input port of the bending die in the second state is also facing the wire 2000, which can ensure that during the bending process of the wire 2000, the formed coils 600 are arranged in the same plane. This not only facilitates the subsequent shaping of the wound coils 600, but also can improve the protection of the coils 600 during the shaping process.

[0055] As an alternative solution, as Figure 2As shown, the driving assembly 100 includes a first driving member 110 and a flipping member 120. Among them, the first driving member 110 is arranged on the frame 300, the mounting table 200 is arranged on the flipping member 120, the flipping member 120 is connected to the output end of the first driving member 110, and the first driving member 110 can drive the flipping member 120 to rotate around a preset axis. By splitting the driving assembly 100 into the first driving member 110 and the flipping member 120, arranging the mounting table 200 on the flipping member 120, and driving the flipping member 120 to rotate around the preset axis by the first driving member 110, the effect that the bending die on the mounting table 200 rotates around the preset axis and switches between the first state and the second state is achieved. It should be noted that in this embodiment, the first driving member 110 is a rotating motor, a gear is arranged at the output end of the rotating motor, the rotating motor drives the gear to rotate around its central axis, the flipping member 120 is a toothed disc, the gear meshes with the toothed disc, the preset axis is the central axis of the toothed disc, and the gear drives the toothed disc to rotate around the central axis of the toothed disc. The rotating motor has a simple structure, is convenient for disassembly and assembly, and has a stable output power. In other embodiments, the first driving member 110 can also be a rotating cylinder or other rotating driving structures, and this embodiment does not make specific limitations.

[0056] In addition, as Figure 2 shown, an avoidance opening 121 is arranged on the flipping member 120. The wire 2000 passes through the avoidance opening 121 and is then conveyed to the bending die. The structure is compact and the design is ingenious, effectively saving the installation space.

[0057] In addition, the driving assembly 100 further includes a transmission member. Among them, the input end of the transmission member is in gear meshing with the output end gear of the first driving member 110, the output end of the transmission member is in gear meshing with the flipping member 120, and the transmission member is configured to reduce the rotation speed of the flipping member 120 around the preset axis. By additionally arranging the transmission member, and respectively meshing the input end of the transmission member with the output end gear of the first driving member 110 and meshing the output end of the transmission member with the flipping member 120, the rotation speed of the flipping member 120 around the preset axis is reduced to meet the actual working requirements. It should be noted that in this embodiment, the transmission member is a gear set, and the mutual meshing of the gears in the gear set is used to reduce the rotation speed of the flipping member 120 around the preset axis. In other embodiments, the transmission member can also be arranged to increase the rotation speed of the flipping member 120 around the preset axis, or the transmission member can be arranged as a bevel gear set to change the transmission direction of the first driving member 110, and this embodiment does not make specific limitations.

[0058] In an alternative solution, as Figure 2As shown in the figure, the bending die flipping device further includes a locking assembly 400. Among them, the locking assembly 400 can tightly fix the flipping member 120 to the frame 300. By setting the locking assembly 400 to tightly fix the flipping member 120 to the frame 300, it can prevent the bending die on the mounting table 200 from deflecting in the first state or the second state, and improve the winding effect of the subsequent wire 2000 on the bending die.

[0059] Specifically, the locking assembly 400 includes a second driving member 410 and an abutting member 420. Among them, the second driving member 410 is arranged on the frame 300, the abutting member 420 is connected to the output end of the second driving member 410, the abutting member 420 and the frame 300 are respectively arranged at two opposite ends of the flipping member 120, and the second driving member 410 can drive the abutting member 420 to move towards the direction close to the frame 300. By respectively arranging the abutting member 420 and the frame 300 at two opposite ends of the flipping member 120, connecting the output end of the second driving member 410 to the abutting member 420, and driving the abutting member 420 to move towards the direction close to the frame 300 by the second driving member 410, the flipping member 120 can be tightly abutted between the frame 300 and the abutting member 420, with a simple structure and ingenious design. It should be noted that in this embodiment, the second driving member 410 is a linear cylinder. The linear cylinder drives the abutting member 420 to move towards the direction close to the frame 300. The linear cylinder has a simple structure, sensitive response, and convenient disassembly and assembly. In other embodiments, the second driving member 410 can also be a linear motor or other linear driving structures, and this embodiment does not make specific limitations.

[0060] To further improve the protection of the flipping member 120, an elastic buffer layer is provided on the end face of the abutting member 420 close to the flipping member 120, and an elastic buffer layer is provided on the end face of the frame 300 close to the flipping member 120. By respectively providing elastic buffer layers on the end face of the abutting member 420 close to the flipping member 120 and the end face of the frame 300 close to the flipping member 120, when the frame 300 and the abutting member 420 jointly tightly fix the flipping member 120, the elastic buffer layer can solve the problem that the frame 300 and the abutting member 420 directly contact the flipping member 120, and solve the problems of bumping, scratching or abrasion caused by the direct contact between the frame 300 and the abutting member 420 and the flipping member 120. It should be noted that in this embodiment, the elastic buffer layer is made of rubber material. The rubber material has good elasticity, toughness and wear resistance, and a long service life. In other embodiments, the elastic buffer layer can also be made of sponge, cotton or other elastic materials, and this embodiment does not make specific limitations. It can be understood that in other embodiments, an elastic buffer layer can be provided only on the end face of the abutting member 420 close to the flipping member 120, or only on the end face of the frame 300 close to the flipping member 120, or elastic buffer layers can be respectively provided on both end faces of the flipping member 120 close to the frame 300 and the abutting member 420, and this embodiment does not make specific limitations.

[0061] In an alternative embodiment, to further improve the locking effect of the locking assembly 400 on the flipping member 120, the end face of the abutting member 420 close to the flipping member 120 is spacedly covered with protrusions or grooves, and the end face of the frame 300 close to the flipping member 120 is spacedly covered with protrusions or grooves. By spacingly covering the end face of the abutting member 420 close to the flipping member 120 and the end face of the frame 300 close to the flipping member 120 with protrusions or grooves, the surface roughness of the end face of the abutting member 420 close to the flipping member 120 and the end face of the frame 300 close to the flipping member 120 can be increased, thereby increasing the frictional force between the abutting member 420 and the flipping member 120 and the frictional force between the frame 300 and the flipping member 120 to improve the locking effect of the locking assembly 400 on the flipping member 120. It should be noted that in other embodiments, only the end face of the abutting member 420 close to the flipping member 120 can be spacedly covered with protrusions or grooves, or only the end face of the frame 300 close to the flipping member 120 can be spacedly covered with protrusions or grooves, or the two end faces of the flipping member 120 close to the frame 300 and the abutting member 420 can be spacedly covered with protrusions or grooves respectively. This embodiment does not make specific limitations.

[0062] As an alternative embodiment, the bending die flipping device is provided with at least two sets of locking assemblies 400. The at least two sets of locking assemblies 400 are spacedly arranged along the outer periphery of the flipping member 120, and the at least two sets of locking assemblies 400 simultaneously abut and fix the flipping member 120 and the frame 300. It should be noted that in this embodiment, the bending die flipping device is provided with two sets of locking assemblies 400. The two sets of locking assemblies 400 are respectively arranged along the left-right direction on the outer periphery of the flipping member 120, and the two sets of locking assemblies 400 simultaneously abut and fix the flipping member 120 and the frame 300. In other embodiments, the number of the locking assemblies 400 can also be arbitrarily adjusted within the range of two sets and above according to actual requirements. This embodiment does not make specific limitations.

[0063] In addition, in other embodiments, the locking assembly 400 can be a bolt. A through hole is formed in the flipping member 120, and a threaded blind hole is formed in the frame 300. After the bolt passes through the through hole, it is threadedly fixed to the threaded blind hole to realize the locking of the flipping member 120. This embodiment does not make specific limitations. It can be understood that the locking assembly 400 can also be a positioning pin. A positioning through hole is formed in the flipping member 120, and a positioning blind hole is formed in the frame 300. The positioning pin is sequentially inserted and fixed to the positioning through hole and the positioning blind hole.

[0064] In an alternative embodiment, such as Figure 2As shown, the bending die flipping device further includes a detection component 500. Among them, the detection component 500 is arranged on the frame 300, and the detection component 500 is communicatively connected to the driving component 100. The detection component 500 is used to detect whether the bending die on the mounting table 200 is in the first state or the second state. Specifically, the detection component 500 includes a position sensor and a controller. The position sensor and the first driving member 110 are both communicatively connected to the controller. The position sensor is used to detect whether the bending die on the mounting table 200 is in the first state or the second state. The position sensor transmits the detection information to the controller, and the controller controls the start and stop of the first driving member 110 according to the detection information, so that the bending die on the mounting table 200 is in the first state or the second state.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
