Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stator wire processing, and in particular to a stator wire split-drawing forming device. BACKGROUND

[0002] In the field of motor manufacturing, the stator is the core component for realizing the conversion of electric energy and mechanical energy, and the forming quality of its winding directly determines the running accuracy, efficiency and service life of the motor. As a key link in winding processing, stator wire forming needs to precisely bend, pull and shape the wire through specific processes and equipment to adapt to the slot structure of the stator core and the electromagnetic performance requirements of the motor. With the rapid development of new energy, intelligent manufacturing and other industries, the market demands smaller, more efficient and longer-lasting motors, and the stator wire forming process faces higher technical challenges.

[0003] Current stator wire forming equipment on the market is mostly general mechanical structure, lacking special design for the characteristics of stator wire. Some equipment can only achieve simple wire bending and cannot complete multi-dimensional pulling and shaping; some equipment has pulling function, but the control precision of pulling force and rotation angle is insufficient, and lacks effective limiting and positioning mechanism, resulting in poor consistency of stator wire forming in different batches.

[0004] In addition, the adaptability of existing equipment is weak. For different specifications and materials of stator wire, the mold needs to be frequently replaced or the mechanical structure needs to be adjusted, which is tedious and time-consuming, and cannot meet the flexible production demand. In high-precision forming scenarios, mechanical clearance and motion error of the equipment will be directly transmitted to the wire, causing the formed stator winding to fail to accurately embed into the core slot, and manual secondary trimming is required, which not only reduces production efficiency, but also increases labor cost and wire loss.

[0005] In summary, due to the problems of structural design defects, insufficient positioning accuracy and single function, the existing stator wire forming process and equipment cannot balance reliability and precision of forming and positioning, and cannot meet the requirements of modern motors for high precision and high stability. Therefore, it is an urgent need for the industry to develop a forming device that can realize precise pulling and forming of stator wire, adapt to complex structure layout and ensure long-term stable operation of the motor.

[0006] In view of the above-mentioned defects, the present design person actively researches and innovates to create a stator wire split-drawing forming device, which has more industrial value. SUMMARY

[0007] To solve the above technical problems, the purpose of the present application is to provide a stator wire split-drawing forming device.

[0008] The application discloses a stator wire splitting forming device.

[0009] The stator wire splitting forming device has a simple and exquisite structure, the base at the bottom stably bears the whole device, the mounting shaft erected at the end thereof serves as a core support, the rotating ring on the shaft can be flexibly rotated through the bearing and is tightly connected with the rotating seat above, the fixing hole at the top end of the mounting shaft can stably lock one end of the stator wire, and the multiple pulling holes distributed on the rotating seat can be respectively inserted into different parts of the wire; when the rotating seat rotates along with the rotating ring, the pulling holes can form uniform and stable pulling force on the wire, and the originally regular wire can be easily split and formed according to requirements, the whole process is smooth and efficient, the wire after forming has a regular shape and can well meet the assembly requirements of subsequent stator processing.

[0010] Further, the top end of the mounting shaft is provided with an upward protruding stopper, and the stopper is used for sleeving the stator wire bending return bend.

[0011] The top end of the mounting shaft protrudes a stopper upward, which serves as a precise "bending fulcrum", when the stator wire needs to be processed into a bending return bend, the wire head is only needed to be sleeved on the stopper, the stopper can stably bear the bending force of the wire, the bending process of the wire head becomes smooth and regular, the required return bend is easily formed, the problems such as deviation and deformation of the wire during bending are avoided, and subsequent processing and assembly are more convenient.

[0012] Further, a vertical limiting block is fixed to the upper edge of the rotating seat, and a limiting baffle is fixed to one side of the mounting shaft, and the limiting block can be in contact with the side wall of the limiting baffle after the rotating seat rotates.

[0013] The upper edge of the rotating seat is vertically fixed with a limiting block, and the limiting baffle is fixed to one side of the mounting shaft, and the two are matched to realize distortion positioning; when the rotating seat rotates with the limiting block, the limiting block approaches the limiting baffle along the rotating track, and finally accurately contacts the side wall of the limiting baffle, thereby stably stopping the further rotation of the rotating seat, avoiding the deviation from the preset position due to excessive rotation, keeping the rotating action of the whole device within a controllable range, and greatly improving the accuracy of the stator wire splitting forming.

[0014] Further, a plurality of mounting screw holes are arranged on the surface of the rotating seat, and the limiting block is fixed in any mounting screw hole through a bolt.

[0015] The surface of the rotating seat is arranged with a plurality of mounting screw holes, and the limiting block can be fixed in any one of the screw holes by bolts, so that the installation process is simple and convenient and firm, the position of the limiting block can be easily adjusted according to different needs of the stator wire splitting forming, the limiting range of the device can be flexibly adapted to various processing scenes, different forming requirements can be met without replacing the rotating seat, and the adaptability and use flexibility of the equipment are greatly improved.

[0016] Further, the outer side of the limiting block has a screw hole, a limiting bolt is selected into the screw hole, a nut is selected into the threaded section of the limiting bolt, the nut is in contact with the side wall of the limiting block, and the end of the limiting bolt can be in contact with the limiting block.

[0017] The outer side of the limiting block is provided with a screw hole, and a limiting bolt can be screwed into the screw hole. The threaded section of the bolt also has a nut, and the nut is tightly attached to the side wall of the block to securely lock the bolt. By turning the bolt, its extension length can be easily changed. When the rotating seat drives the limiting block to rotate, the end of the bolt can accurately touch the limiting block. This avoids direct impact of the limiting block on the block, causing wear and tear. It can also adjust the rotation limit of the rotating seat according to the processing needs, making the entire limiting process softer and the positioning more accurate.

[0018] Further, the two sides of the rotating seat are fixed with force rods.

[0019] Each of the two sides of the rotating seat is fixed with a force rod. When the operator holds the force rod and applies force, the force can be easily transmitted to the rotating seat. The originally laborious rotating action becomes labor-saving and smooth. Even if the rotating operation needs to be completed to split and form the wire, the rotation rhythm and intensity can be easily controlled to avoid deviation in wire forming caused by uneven force. This makes the entire processing process more efficient and easier to operate.

[0020] Through the above scheme, the present application has at least the following advantages: I. Improve the forming precision and consistency to ensure the processing quality; The device cooperates with multiple components to build a precise forming and limiting system: the fixed hole at the top of the mounting shaft cooperates with the multiple pulling holes on the rotating seat to form stable and uniform pulling force on different parts of the stator wire, avoiding deformation deviation of the wire caused by uneven force in traditional equipment, and ensuring the regular shape of the wire after forming; the limiting block of the rotating seat and the limiting block of the mounting shaft form a basic positioning mechanism, which can not only accurately control the rotation limit of the rotating seat to avoid forming errors caused by excessive rotation, but also reduce the impact of components by buffering the bolt, further improving the positioning accuracy. This multi-level precise control effectively solves the problem of poor consistency of existing equipment, making the forming quality of different batches of stator wires stable and uniform, accurately adapting to the assembly requirements of subsequent stator cores, and reducing the manual secondary trimming process.

[0021] II. Enhance equipment adaptability to meet the needs of flexible production; The device has high flexibility adjustment capability, which can adapt to various processing scenes: the rotating seat surface distributes multiple mounting screw holes, allowing the limiting block to be fixed at any position through the bolt, combined with the telescopic limiting bolt on the limiting block, the limiting range and forming parameters can be flexibly adjusted according to the forming requirements of different specifications and different material stator wires; without replacing the rotating seat or the core mold, the adjustment can be completed by simply adjusting the position of the parts, greatly shortening the equipment adjustment cycle. This flexible design breaks the dependence of traditional equipment on specific wires, and can meet the diversified production needs of motors in the fields of new energy and intelligent manufacturing, improving the versatility and industrial utilization value of the equipment.

[0022] III. Optimize operation convenience and improve production efficiency; The device fully considers the operational convenience in the structural design: the force rods on both sides of the rotating seat can efficiently transmit the force of the operator to the rotating seat, making the originally laborious rotating and pulling action become labor-saving and smooth, and facilitating precise control of the rotation rhythm and intensity; the connection and adjustment structure of each part is simple and intuitive, such as the bolt fixation of the limiting block and the screwing adjustment of the limiting bolt, which can be quickly operated without professional skills, reducing personnel training costs. At the same time, the precise forming and limiting design reduces the processing errors and rework rate, and the convenient operation process significantly improves the processing efficiency of the stator wire, effectively reducing the labor cost and wire loss.

[0023] The above description is only a summary of the technical solutions of the present application. In order to more clearly understand the technical means of the present application, and to implement the content of the specification, the following will be described in detail with the preferred embodiments of the present application and with the aid of the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0024] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following will briefly introduce the drawings needed to be used in the embodiments. It should be understood that the following drawings only show some embodiments of the present application, and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can also be obtained without creative labor.

[0025] Figure 1 is a structural schematic diagram of the present application; Figure 2 is a structural schematic diagram of the present application after removing the rotating ring; Figure 3 is a top view of the present application without force rods; 1, base, 2, mounting shaft, 3, rotating ring, 4, rotating seat, 5, fixed hole, 6, pulling hole, 7, block, 8, limiting block, 9, limiting block, 10, limiting bolt, 11, force rod. DETAILED DESCRIPTION

[0026] The specific embodiments of the present application are described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0027] Referring to Figure 1 and Figure 2 When the stator wire splitting forming device is working, first, the base 1 is stably installed on the operation platform, one end of the stator wire is inserted into the fixing hole 5 at the top end of the mounting shaft 2 to complete positioning and fixing, and then the different parts of the wire that need to be split are correspondingly inserted into the multiple pulling holes 6 on the rotating seat 4. The operator pushes the rotating seat 4. Since the rotating seat 4 is fixedly connected with the rotating ring 3 mounted on the mounting shaft 2, and the rotating ring 3 can flexibly rotate along the mounting shaft 2 through the bearing, the rotating seat 4 will drive the pulling holes 6 to rotate synchronously, and the pulling holes 6 will exert uniform pulling force on the wire inserted therein, so as to split and form the wire according to the requirements. The base 1 provides stable support for the entire device to avoid shaking during operation and affect the forming effect; the mounting shaft 2 as the core bearing structure cooperates with the rotating ring 3 connected by the bearing to make the rotation of the rotating seat 4 more smooth and labor-saving, and reduce mechanical loss; the cooperation of the fixing hole 5 and the multiple pulling holes 6 can accurately fix different parts of the wire, make the pulling force uniformly transmitted, and ensure that the formed wire has regular shape, effectively solving the forming deviation problem caused by uneven stress in traditional processing.

[0028] In the stator wire splitting forming process, when the wire needs to be bent and turned into an elbow, the wire head of the stator wire can be naturally sleeved on the protruding stop block 7 at the top end of the mounting shaft 2, and the stop block 7 is used as a fulcrum to exert a bending force on the wire. The stop block 7 stably receives the bending force of the wire and guides the wire to form a regular elbow along the preset track. The protruding stop block 7 at the top end of the mounting shaft 2 provides a precise positioning fulcrum for wire bending, avoiding problems such as wire head deviation and deformation during bending, making the elbow forming process smoother, and ensuring the consistency of the bending size; at the same time, the protruding structure of the stop block 7 facilitates the quick sleeving and disengaging of the wire, simplifies the operation steps, and further improves the quality and efficiency of the stator wire processing in cooperation with the overall forming process of the device.

[0029] Referring to Figure 3When the operator rotates the rotating seat 4 to pull the wire, the limiting block 8 fixed on the rotating seat 4 rotates synchronously with the rotating seat 4. When the rotating seat 4 rotates to the preset angle, the limiting block 8 will be in precise contact with the side wall of the limiting block 9 fixed on one side of the mounting shaft 2, thereby blocking the rotating seat 4 from continuing to rotate, and realizing precise control of the rotation angle. The cooperation of the limiting block 8 and the limiting block 9 forms a reliable mechanical limiting mechanism, which can effectively avoid the deviation of the wire pulling forming angle caused by the over-rotation of the rotating seat 4, and ensure the forming precision and consistency of each wire; and both of them are fixed and installed structures, which realize automatic limiting according to the rotation track of the rotating seat 4, without the need for real-time control of the rotation angle by manual operation, thereby simplifying the operation difficulty and improving the stability and safety of the processing process.

[0030] When adjusting the limiting position according to the splitting and forming requirements of different specifications of stator wires, the operator can first loosen the bolts fixing the limiting block 8, move the limiting block 8 to the corresponding position in the multiple mounting screw holes on the surface of the rotating seat 4 according to the preset rotation angle requirement, and then firmly fix the limiting block 8 in the mounting screw hole through the bolts. After completing the adjustment of the limiting position, the forming operation can be carried out. The multiple mounting screw holes on the surface of the rotating seat 4 provide multiple fixing points for the limiting block 8, and the position switching of the limiting block 8 can be quickly realized through the bolt fixing mode, without the need to replace the rotating seat 4 to adapt to the forming angle requirements of different wires; and the stable and reliable bolt fixing connection mode can ensure that the limiting block 8 does not shift during operation, thereby improving the adaptability of the equipment to multiple scenes, ensuring the limiting precision, simplifying the adjustment operation process, and reducing the equipment debugging difficulty.

[0031] Before the splitting and forming operation of the stator wire, the operator can rotate the limiting screw 10 into the screw hole outside the limiting block 9 according to the processing requirement, adjust the extension length of the limiting screw 10 by turning it, and after the position is determined, screw the nut into the threaded section of the limiting screw 10 and make it tightly adhere to the side wall of the limiting block 9, to realize the locking of the limiting screw 10. During operation, when the rotating seat 4 rotates the limiting block 8 to the preset position, the limiting block 8 will be in contact with the end of the limiting screw 10, thereby limiting the further rotation of the rotating seat 4. The screw hole of the limiting block 9 provides a stable installation basis for the limiting screw 10, which can be flexibly adjusted by turning the bolt, and the nut locking can ensure that the bolt does not loosen during operation, thereby meeting the fine requirements of different wires on the rotation limit; and the contact between the limiting screw 10 and the limiting block 8 replaces the direct collision between the limiting block 8 and the limiting block 9, which reduces the component wear, and the precise limiting adjustment can further improve the wire forming precision, taking into account the adaptability, durability and processing quality of the equipment.

[0032] In the stator wire splitting forming operation, the operator holds the force bars 11 fixed on both sides of the rotating seat 4 with both hands, applies a pushing force or a pulling force in the preset direction, the force bars 11 transmit the force to the rotating seat 4, drive the rotating seat 4 to rotate flexibly along the mounting shaft 2 with the rotating ring 3, and then complete the forming operation by applying a pulling force to the wire through the pulling holes 6; if the rotating speed or the force needs to be adjusted, the operator can accurately control the position and the force by holding the force bars 11. The force bars 11 lengthen the lever arm, so that the operator can easily drive the rotating seat 4 to rotate without consuming too much force, which effectively reduces the operation strength; at the same time, the symmetrical force bars 11 on both sides facilitate the operator to stably apply force, avoid the rotating seat 4 from rotating deviation due to uneven force, ensure the uniform force of the wire, and improve the forming precision; in addition, the force bars 11 provide a clear force fulcrum for the operator, simplify the operation process, enable beginners to quickly get started, and further improve the processing efficiency and operation safety.

[0033] The working principle of the present application is as follows: Before operation, the base 1 is first stably installed on the operation platform to provide stable support for the entire device. Then the wire fixing is carried out: one end of the stator wire is inserted into the fixed hole 5 at the top end of the mounting shaft 2 to complete positioning, and different parts of the wire to be split and pulled are correspondingly inserted into the plurality of pulling holes 6 on the rotating seat 4. If the wire needs to be bent to form a return bend, the wire end can be sleeved on the stop block 7 at the top end of the mounting shaft 2, and a bending force is applied with the stop block 7 as a fulcrum to guide the wire to form a regular bend.

[0034] Limit adjustment also needs to be completed before operation: according to the wire forming angle requirement, loosen the bolts fixing the limiting blocks 8, move them to the corresponding mounting screw holes on the surface of the rotating seat 4 and re-fix them; then rotate the limiting bolts 10 into the screw holes outside the limiting bars 9, adjust the length of the limiting bolts 10 after being extended, and lock them with nuts close to the side wall of the limiting bars 9.

[0035] In formal operation, the operator holds the force bars 11 on both sides of the rotating seat 4 with both hands, applies force in the preset direction, and the force bars 11 transmit the force to the rotating seat 4. Since the rotating seat 4 is fixedly connected with the rotating ring 3 mounted on the mounting shaft 2, and the rotating ring 3 can rotate flexibly along the mounting shaft 2 through the bearing, the rotating seat 4 drives the pulling holes 6 to rotate synchronously, applies a uniform pulling force to the wire, and completes the splitting and forming. During the rotating process, when the limiting blocks 8 on the rotating seat 4 rotate to contact the end of the limiting bolts 10, the rotating seat 4 stops rotating, realizing accurate control of the rotating angle.

[0036] Finally should be explained a few points are: first, in the description of the present application, it should be pointed out that, unless otherwise specified and limited, the term "installation", "connected", "connection" should be broad, can be mechanical or electrical connection, but also can be two elements inside the communication, can be directly connected, "up", "down", "left", "right" and so on, only for indicating the relative position relationship, when the absolute position of the described object changes, the relative position relationship may change; Second: the present application discloses embodiment in the drawings, only involves the structure related to the present disclosure embodiment, other structure can refer to the usual design, in the case of no conflict, the same embodiment and different embodiments of the present application can be combined with each other; Finally: the above only is the preferred embodiment of the present application, and does not limit the present application, it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, can make a number of improvements and variations, these improvements and variations should also be considered the protection scope of the present application.
