Description

Technical Field

[0001] The utility model relates to the technical field of flat wire forming equipment, in particular to a flat wire one-way forming device. Background Art

[0002] The motor with rectangular cross-section wire in the stator winding is called flat wire motor (also called Pin motor). Unlike ordinary wound-wire motors, flat wire motors do not first wind round wires into specific coils and then insert them into stator slots by machines. Instead, flat wires (also called flat copper wires, collectively referred to as flat wires below for the sake of uniform technical terms) are preformed, inserted into stator slots, and re-formed and welded at one or both ends to form the entire stator winding. Flat wire is conducive to improving the slot fill rate of motors. Generally, the slot fill rate of round wire motors is about 50%, while the slot fill rate of flat wire motors can reach more than 70%. According to the winding form of flat wire motors, they can be divided into Hair-pin windings (also called hairpin windings, collectively referred to as Hair-pin windings below), I-Pin windings, wave windings, etc. At present, Hair-pin is the mainstream, and the production process of Pin coil includes straightening, paint removal, cutting and molding, among which the molding step is stamping molding, first plane and then three-dimensional molding. However, the existing molding equipment is expensive, complex in structure and too large in size. Utility Model Content

[0028] As Figures 1 to 6 shown, the flat wire unidirectional forming device 100 provided in this embodiment includes a base 10 and a bending device 20; the bending device 20 includes a hollow base 21 installed on the base 10 and a bending assembly 22 for bending the flat wire 200; the base 21 includes a mounting plate 211 at its top, the bending assembly 22 includes a fixed shaft member 23 and a bending member 24 rotatably arranged on the outer periphery of the fixed shaft member 23 with the axis of the fixed shaft member 23 as the axis, the fixed shaft member 23 is arranged in the base 21 and its top end extends beyond the mounting plate 211 and forms a guiding channel 231 for the flat wire 200 to pass through; the bending device 20 further includes a bending driving assembly 25 for driving the bending member 24 to bend the flat wire 200 located outside the guiding channel 231 relative to the flat wire 200 inside the guiding channel 231 around the fixed shaft member 23, the bending driving assembly 25 is supported on the mounting plate 211, and a transmission assembly 26 connecting the bending driving assembly 25 and the bending member 24 is arranged in the base 21.

[0029] The above-mentioned flat wire unidirectional forming device 100 includes a base 10 and a bending device 20. The bending device 20 includes a base 21, a bending assembly 22 and a bending drive assembly 25. The bending assembly 22 includes a fixed shaft member 23 having a guiding channel 231 and a bending member 24 rotatable about the axis of the fixed shaft member 23; the bending drive assembly 25 is supported on the mounting plate 211 of the base 21, and a transmission assembly 26 connecting the bending assembly 22 and the bending drive assembly 25 is provided inside the base 21. The bending drive assembly 25 drives the bending member 24 through the transmission assembly 26 to bend the flat wire 200 located outside the guiding channel 231 relative to the flat wire 200 inside. In this way, the structure of the whole machine is compact, the volume is smaller, and the space occupancy rate is low.

[0030] See Figure 1 , the flat wire unidirectional forming device 100 provided in this embodiment includes a base 10 and a bending device 20. The bending device 20 is installed on the base 10 and supported by the base 10. The bending device 20 receives the straightened flat wire 200 sent out by a wire feeding device (not shown in the figure) located on the left side (the left side shown in the figure) of the base 10, and then bends the flat wire 200 into a preset shape.

[0031] Please continue to see Figure 1 , a linear module 11 is provided on the base 10 of this embodiment, which is used to drive the bending device 20 to move relative to the base 10 along the length direction of the base 10. In this embodiment, the flat wire 200 moves to the left along the length direction of the base 10 (the left-right direction shown in the figure). The bending device 20 is installed on the base 10 through the linear module 11. The linear module 11 is any existing linear module 11 in the prior art that can realize the movement of the bending device 20 relative to the base 10 along the length direction of the base 10. It is worth mentioning that the flat wire 200 formed by the above bending device 20 is in the shape of a hairpin, that is, the flat wire 200 needs to be bent three times. First, set the required dimensional parameters of the bent flat wire 200. After the flat wire 200 is fed into the bending device 20 to reach the predetermined length, stop the feeding of the flat wire 200, and at the same time drive the bending device 20 to bend the flat wire 200 at the initial position; after the first bending, the bending device 20 moves to the right (the right side direction shown in the figure) by a preset stroke to the second position to bend the flat wire 200; after the second bending, the bending device 20 moves to the right (the right side direction shown in the figure) by a preset stroke to the third position to bend the flat wire 200; after three bends, move to the left (the left side direction shown in the figure) to reset, and repeat the above actions.

[0032] In other embodiments, the bending device 20 can be fixed on the base 10, and the change of the bending position is realized by the feeding of the wire feeding device.

[0033] See Figures 1 to 6, the bending device 20 provided in this embodiment includes a base 21 and a bending assembly 22. The base 21 is a hollow structure, and the bending assembly 22 is used to bend the flat wire 200 and is installed on the base 21. The base 21 includes a mounting plate 211. The bending assembly 22 includes a fixed shaft member 23 and a bending member 24 rotatably arranged about the axis of the fixed shaft member 23. The fixed shaft member 23 is arranged inside the base 21 and its top end extends out of the mounting plate 211 and forms a guiding channel 231 for the flat wire 200 to pass through; the bending device 20 further includes a bending driving assembly 25 for driving the bending member 24 to bend the flat wire 200 around the fixed shaft member 23, and a transmission assembly 26 is arranged inside the base 21. In this embodiment, the base 21 is installed on the base 10 through a linear module 11. The base 10 includes a mounting plate 211, and the mounting plate 211 is located at the top of the base 21. The bending assembly 22 includes a fixed shaft member 23 and a bending member 24. The fixed shaft member 23 includes a shaft member 232, a guiding seat member 233, and a cover member 234 connected in sequence from bottom to top (the up and down directions shown in the figure). The shaft member 232 is fixedly installed inside the base 21 by all existing fixing methods such as screws and is perpendicular to the mounting plate 211. The upper end (the upper end shown in the figure) of the shaft member 232 extends upward and out of the mounting plate 211. The guiding seat member 233 is fixedly installed on the shaft member 232 by all existing fixing methods such as screws. The guiding seat member 233 is made of a material with a higher hardness than that of the shaft member 232. The cover member 234 is fixedly installed on the guiding seat member 233 by all existing fixing methods such as screws and jointly forms the guiding channel 231 with the guiding seat member 233 for the flat wire 200 to pass through. The bending member 24 is located at the wire outlet position of the guiding channel 231 and can rotate around the fixed shaft member 23. While rotating, it abuts against the side wall of the flat wire 200 and drives the flat wire 200 to bend relative to the flat wire 200 inside the guiding channel 231. The bending driving assembly 25 is arranged substantially side by side with the bending assembly 22 and is used to drive the bending member 24 to rotate around the fixed shaft member 23 to bend the flat wire 200 outside the guiding channel 231 relative to the flat wire 200 inside around the wire outlet of the fixed shaft member 23. The bending driving assembly 25 is fixedly installed on the mounting plate 211 by all existing fixing methods such as screws and is supported by the mounting plate 211. A transmission assembly 26 connecting the bending assembly 22 and the bending driving assembly 25 is arranged inside the base 21. In this way, the bending driving assembly 25 controls the rotation of the bending member 24 through the transmission assembly 26 to realize the bending of the flat wire 200 into a hairpin shape.

[0034] See Figures 1 to 6 , the bending member 24 provided in this embodiment includes an annular seat member 241 sleeved on the fixed shaft member 23 and a roller member 242 installed on the annular seat member 241 and used to abut against the side wall of the flat wire 200.

[0035] See Figures 1 to 6 Figures 1 to 6 , the transmission assembly 26 provided in this embodiment includes a transmission rotating shaft 261 that is in transmission connection with the bending drive assembly 25, a transmission gear 262 that is key-connected to the transmission rotating shaft 261, and a driven gear 263 that meshes with the transmission gear 262. The driven gear 263 is sleeved outside the fixed shaft member 23 and is fixedly connected to the bending member 24. In this embodiment, the bending drive assembly 25 includes a motor and a reducer that are connected to each other. The bottom end of the transmission rotating shaft 261 is supported on the base 21 by a bearing, the top end of the transmission rotating shaft 261 is connected to the reducer, the axis of the transmission rotating shaft 261 is substantially parallel to the axis of the shaft member 232, the transmission gear 262 is sleeved on the transmission rotating shaft 261, and the two are non-rotatably connected by a key pin. The driven gear 263 is installed on the shaft member 232 of the fixed shaft member 23 through a bearing. The annular seat member 241 of the bending member 24 is fixedly installed on the end face of the driven gear 263 by all existing fixing methods such as screws. In this way, driven by the motor of the bending drive assembly 25, the transmission rotating shaft 261 and the transmission gear 262 rotate, driving the driven gear 263 and the bending member 24 to rotate.

[0036] See Figure 2 and Figure 3 Figure 3 , in this embodiment, both the transmission gear 262 and the driven gear 263 are, but not limited to, helical gears. In this way, with the transmission structure of helical gears, the meshing characteristics are good and the contact ratio is large.

[0037] See Figures 1 to 6 Figures 1 to 6 , the base 21 provided in this embodiment is provided with a receiving cover plate 212 for abutting against the flat wire 200 and allowing the flat wire 200 to slide on the surface of the receiving cover plate 212. The top surface of the receiving cover plate 212 is flush with the bottom surface of the guiding channel 231. In this embodiment, the receiving cover plate 212 is installed on the mounting plate 211 through a connecting block. The receiving cover plate 212 is provided with holes corresponding to the bending assembly 22 for the fixed shaft member 23 and the bending member 24 to pass through. It should be noted that by supporting the flat wire 200 by the receiving cover plate 212, the up-and-down movement of the flat wire 200 during movement and bending can be avoided.

[0038] See Figures 1 to 6, a cutting device 30 is provided on the base 10 provided in this embodiment. The cutting device 30 includes a cutter base 31, a tool member 32 that is liftably disposed in the cutter base 31, and a tool driving mechanism 33 that is used to drive the tool member 32 to lift and move downward to cut off the bent flat wire 200. The cutting device 30 can be fixed on the base 10 or installed on the base 10 in the manner of a linear driving module. It can be understood that the cutting device 30 is disposed downstream of the bending device 20 along the wire feeding direction (the length direction of the illustrated base). In this way, after the flat wire 200 is bent three times by the cutting device 30, the bent flat wire 200 can be cut off from the flat wire 200 to be bent by the cutting device 30. This structure can realize the continuous wire feeding, forming, and cutting of the flat wire 200, thereby improving the production efficiency and achieving mass production.

[0039] See Figure 1 , Figure 4 and Figure 6, the tool driving mechanism 33 provided in this embodiment includes a driving rotating shaft 331, a tool fixing seat 332, a control lever 333, and a tool driving assembly 334. The driving rotating shaft 331 includes a shaft body portion 335 rotatably mounted in the cutter holder 31 and a connecting shaft portion 336 located at the end of the shaft body portion 335 and having a circular cross-section. The axis of the connecting shaft portion 336 is offset from the axis of the shaft body portion 335; the tool fixing seat 332 is located below the driving rotating shaft 331, and includes a fixing seat body 337 for mounting the tool member 32 and a fixing seat shaft 338 connecting the fixing seat body 337 and having an axis parallel to the axis of the connecting shaft portion 336; one end of the control lever 333 is rotatably connected to the connecting shaft portion 336, and the other end is rotatably connected to the fixing seat shaft 338; the tool driving assembly 334 is used to rotate the shaft body portion 335. In this embodiment, the tool driving assembly 334 includes a motor and a reducer connected to each other. The shaft body portion 335 has a circular cross-section and is rotatably supported by bearings at the upper part of the cutter holder 31. One end of the shaft body portion 335 is connected to the tool driving assembly 334 and can rotate relative to the cutter holder 31 about the axis of the shaft body portion 335 under the drive of the tool driving assembly 334. A connecting shaft portion 336 is formed at the other end. The connecting shaft portion 336 has a circular cross-section. The axis of the connecting shaft portion 336 is parallel to the axis of the shaft body portion 335 and the axis of the connecting shaft portion 336 is offset from the axis of the shaft body portion 335. The tool fixing seat 332 is liftably mounted at the lower part of the cutter holder 31, located below the driving rotating shaft 331, and includes a fixing seat body 337 and a fixing seat shaft 338 connecting the fixing seat body 337 and having an axis parallel to the axis of the connecting shaft portion 336. The tool member 32 is detachably mounted on the fixing seat body 337. One end of the control lever 333 is rotatably connected to the connecting shaft portion 336 through a bearing, and the other end is rotatably connected to the fixing seat shaft 338 through a bearing. In this way, under the drive of the tool driving assembly 334, the shaft body portion 335 rotates and drives the connecting shaft portion 336 connected to the control lever 333 to rotate about the axis of the shaft body portion 335, thereby driving the tool fixing seat 332 connected to the control lever 333 to move up and down relative to the cutter holder 31. When moving downward, the tool fixing seat 332 drives the tool member 32 to cut off the flat wire 200 located below.

[0040] See Figure 1 , Figure 4 and Figure 6, the tool fixing seat 332 provided in this embodiment further includes a wire pressing block 339. A tool through hole 339a for the tool component 32 to pass through and a wire pressing groove 339b for the flat wire 200 to be placed are formed on the wire pressing block 339. The wire pressing block 339 is connected to the fixing seat body 337 in a liftable manner, and an elastic member 34 is arranged between the wire pressing block 339 and the fixing seat body 337. In this way, driven by the tool driving assembly 334, the tool fixing seat 332 drives the wire pressing block 339 to move downward together and contact the flat wire 200. The wire pressing block 339 presses the flat wire 200 into the wire pressing groove 339b to position and hold the flat wire 200. As the tool fixing seat 332 continues to move downward, the elastic member 34 is compressed, and the tool component 32 passes through the tool through hole 339a of the wire pressing block 339 and cuts the flat wire 200; after the tool fixing seat 332 moves upward, the wire pressing block 339 resets under the elastic force of the elastic member 34 and its own gravity. It can be understood that after the tool fixing seat 332 moves downward, the wire pressing block 339 first contacts the flat wire 200. Under the elastic force of the elastic member 34, it can be ensured that the wire pressing block 339 presses the flat wire 200 into the wire pressing groove 339b, so as to position and hold the flat wire 200.

[0041] See Figure 1 , Figure 4 and Figure 6 , the tool component 32 provided in this embodiment has an air guide groove 321. The air guide groove 321 penetrates the top and bottom of the tool component 32, and an air connection port 337a communicating with the air guide groove 321 and used for connecting an external air source is arranged on the fixing seat body 337. In this way, after the cutting operation, gas is blown into the air guide groove 321 through the air connection port 337a to blow off the slag attached to the tool component 32.

[0042] See Figure 1 , Figure 4 and Figure 6 , the cutting tool seat 31 provided in this embodiment is provided with a blanking pipeline 35 at the bottom. The blanking pipeline 35 is connected to a blanking box 36. In this way, the blown-off slag can be sent into the blanking box 36 through the blanking pipeline 35.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
