[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0038] As Figures 1 to 13 shown, an efficient spring winding device provided by an embodiment of the present invention includes: a frame 10, a spring winding device 20, a first power mechanism 30, a second power mechanism 40, a third power mechanism 50, and a fourth power mechanism 60.

[0039] Among them, multiple groups of spring winding devices 20 are provided and arranged side by side on the frame 10; each group of spring winding devices 20 includes a vertical plate 21, a straightening wheel set 22, a wire feeding wheel set, a wire threading die 24, a forming wheel 25, a push rod 26, and a cutting knife 27; the straightening wheel set 22, the wire feeding wheel set, and the wire threading die 24 are fixedly arranged on the vertical plate 21 in a straight line from back to front, and the vertical plates 21 in multiple groups of spring winding devices 20 are arranged side by side on the frame 10; the forming wheel 25 is distributed on the front side of the wire threading die 24 to control the spring diameter; the push rod 26 is distributed between the wire threading die 24 and the forming wheel 25 to adjust the pitch of the spring; the cutting knife 27 is hinged to the front side of the wire threading die 24 to cut the spring wire.

[0040] The first power mechanism 30 is installed on the frame 10, and the first power mechanism 30 is respectively connected to the wire feeding wheel sets in each group of spring winding devices 20 to synchronously control the wire feeding wheel sets in multiple groups of spring winding devices 20, so as to synchronously feed multiple groups of spring wires into the corresponding wire threading dies 24.

[0041] The second power mechanism 40 is installed on the frame 10, and the second power mechanism 40 is respectively connected to the forming wheels 25 in each group of spring winding devices 20 to synchronously control the interval between the forming wheels 25 and the wire threading dies 24, so as to change and control the spring diameter.

[0042] The third power mechanism 50 is installed on the frame 10, and the third power mechanism 50 is respectively connected to the push rods 26 in each group of spring winding devices 20 to synchronously control the positions of the push rods 26 on the front side of the wire threading die 24. The push rods 26 are biased towards one side of the wire outlet of the wire threading die 24, so that the spring wire is laterally deflected during the winding process, and the pitch of the spring is adjusted by changing the degree of lateral deflection.

[0043] The fourth power mechanism 60 is installed on the frame 10, and the fourth power mechanism 60 is respectively connected to the cutting knives 27 in each group of spring winding devices 20 to synchronously control the rotation of the cutting knives 27 to cut the spring wire.

[0044] Based on the above structural settings, the spring coiling device of this embodiment integrates multiple groups of spring coiling devices 20 within a frame 10, and through the coordination of the first power mechanism 30, the second power mechanism 40, the third power mechanism 50, and the fourth power mechanism 60, synchronously controls the wire feeding wheel set, the forming wheel 25, the push rod 26, and the cutting knife 27 in the spring coiling device 20 respectively. Thereby, the coiling efficiency of the spring is greatly improved, and at the same time, the overall volume of the device is greatly reduced, and the structure and production cost of the device are simplified, having strong practical value and market promotion value.

[0045] To optimize the structure of the device, as a specific implementation manner of the spring coiling device provided in this embodiment, please refer to Figure 2 and Figure 3 As shown, the above-mentioned wire feeding wheel set includes an upper wire feeding shaft 231 and a lower wire feeding shaft 232 that are vertically aligned. On one side of the upper wire feeding shaft 231, there is a first wire feeding gear 233 that is coaxially linked with the upper wire feeding shaft 231. Below the first wire feeding gear 233, there is a second wire feeding gear 234 that is coaxially linked with the lower wire feeding shaft 232, and the first wire feeding gear 233 and the second wire feeding gear 234 are meshed; preferably, the spring coiling device 20 may further include a pressing spring 235, a pull rod 236, a support rod 237, and a spring cylinder 238. The pressing spring 235 is used to press the upper wire feeding shaft 231 against the lower wire feeding shaft 232, and at the same time make the first wire feeding gear 233 and the second wire feeding gear 234 meshed; the support rod 237 is hinged on the vertical plate 21, and both ends of the support rod 237 are respectively connected to the pull rod 236 and the spring cylinder 238. The pull rod 236 is connected to the upper wire feeding shaft 231, and the spring cylinder 236 is used to pull the support rod 236 to rotate, thereby driving the pull rod 236 and the upper wire feeding shaft 231 to rise and separate from the lower wire feeding shaft 232; among them, the first power mechanism 30 includes a driving shaft 31 passing through between multiple spring coiling devices 20 and a first motor 32 for driving the driving shaft 31. The first motor 32 can drive the driving shaft 31 to rotate through structures such as belts, chains, or gears. The distribution direction of the driving shaft 31 is parallel to the axis direction of the first wire feeding gear 233 and the second wire feeding gear 234. A driving gear 33 that is meshed with the second wire feeding gear 234 or the first wire feeding gear 233 is sleeved on the driving shaft 31. Thus, the first motor 32 can be used to drive the driving shaft 31 to rotate, and then drive all the upper wire feeding shafts 231 and the lower wire feeding shafts 232 to rotate synchronously through multiple driving gears 33, so as to synchronously feed the spring wire clamped between the upper wire feeding shaft 231 and the lower wire feeding shaft 232 in each group of spring coiling devices 20 into their respective wire threading dies 24, thereby integrating the power structures of the wire feeding wheel sets in multiple groups of spring coiling devices 20, realizing the synchronous control of multiple groups of wire feeding wheel sets by one first power mechanism 30, and thus achieving the simplification of the structure and the saving of costs.

[0046] To optimize the structure of the device, as a specific implementation manner of the spring coiling device provided in this embodiment, please refer toFigure 4 and Figure 5 As shown in Figure 5 , the second power mechanism 40 described above includes a first linkage arm 41 and a second motor 42. The first linkage arm 41 is perpendicular to the vertical plate 21 and is distributed on the front side of the wire threading die 24. A first mounting seat 43 is provided on the first linkage arm 41 corresponding to each wire threading die 24. The forming wheel 25 is mounted on the first mounting seat 43. The first linkage arm 41 is slidably connected to the vertical plate 21 or the frame 10 through a guide rail distributed in the front-rear direction. The second motor 42 is used to drive the first linkage arm 41 to slide so as to synchronously adjust the distance between all the forming wheels 25 and the corresponding wire threading dies 24. When the spring wire extends forward from the wire outlet of the wire threading die 24, the forming wheel 25 is used to block the spring wire, causing the spring wire to curl. During the continuous curling process, a coiled spring is formed. By adjusting the distance between the forming wheel 25 and the wire threading die 24, the diameter of the coiled spring formed can be changed, thereby changing and controlling the spring diameter. The second motor 42 is used to drive the first linkage arm 41 to slide back and forth, so that the distance between all the forming wheels 25 and the corresponding wire threading dies 24 can be changed and adjusted synchronously, that is, the power structures of the forming wheels 25 in multiple coiled spring devices 20 are integrated, and synchronous control of multiple forming wheels 25 by one second power mechanism 40 is achieved, thereby simplifying the structure and saving costs.

[0047] Further, as a specific implementation manner of the coiled spring device provided in this embodiment, please refer to Figure 4 and Figure 5 As shown in Figure 5 , the second power mechanism 40 described above further includes a first torsion arm 44. A first eccentric swing arm 421 is provided at the output end of the second motor 42. One end of the first torsion arm 44 is hinged to the first eccentric swing arm 421 and the other end is hinged to the first linkage arm 41. When the output shaft of the second motor 42 rotates, the first eccentric swing arm 421 makes a circular motion, thereby driving the first linkage arm 41 to make a reciprocating linear motion in the front-rear direction through the first torsion arm 44. During the process of the first linkage arm 41 making a reciprocating linear motion, the distance between the forming wheel 25 and the wire threading die 24 is adjusted.

[0048] To optimize the structure of the device, as a specific implementation manner of the coiled spring device provided in this embodiment, please refer to Figure 6 and Figure 7As shown in the figure, the above-mentioned third power mechanism 50 includes a second linkage arm 51 and a third motor 52. The second linkage arm 51 is perpendicular to the vertical plate 21 and is distributed on the front side of the wire threading die 24. A second mounting seat 53 is provided below the front side of each wire threading die 24 on the second linkage arm 51. The push rod 26 is installed on the second mounting seat 53. The second linkage arm 51 is slidably connected to the vertical plate 21 or the frame 10 through a guide rail distributed in the left-right direction. The third motor 52 is used to drive the second linkage arm 51 to slide so as to synchronously adjust the positions of all the push rods 26 in front of the corresponding wire threading die 24. The push rod 26 can adopt an inclined distribution method or an inclined plane structure to block the coiling path of the spring, so that the spring is laterally deflected during the coiling process, facilitating the continuous forming of the spring. At the same time, by adjusting the position of the push rod 26, the lateral deflection degree of the spring is changed, and thus the pitch of the spring is changed. By driving the second linkage arm 51 to slide in the left-right direction in front of the wire threading die 24 by the third motor 52, the positions of all the push rods 26 in front of the corresponding wire threading die 24 can be synchronously changed, thereby integrating the power structures of the push rods 26 in multiple sets of spring coiling devices 20, realizing the synchronous control of multiple forming wheels 25 by one third power mechanism 50, and thus simplifying the structure and saving costs.

[0049] Further, as a specific implementation manner of the spring coiling device provided in this embodiment, please refer to Figure 6 and Figure 7 As shown in the figure, the above-mentioned third power mechanism 50 further includes a second torsion arm 54. A second eccentric swing arm 521 is provided at the output end of the third motor 52. One end of the second torsion arm 54 is hinged to the second eccentric swing arm 521 and the other end is hinged to the second linkage arm 51. When the output shaft of the third motor 52 rotates, the second eccentric swing arm 521 makes a circular motion, thereby driving the second linkage arm 51 to make a reciprocating linear motion in the left-right direction through the second torsion arm 54. During the reciprocating linear motion of the second linkage arm 51, the positions of all the push rods 26 in front of the wire threading die 24 are adjusted.

[0050] To optimize the structure of the equipment, as a specific implementation manner of the spring coiling device provided in this embodiment, please refer to Figure 8 and Figure 9As shown, the above-mentioned fourth power mechanism 60 includes a third linkage arm 61 and a fourth motor 62. The third linkage arm 61 is perpendicular to the vertical plate 21 and is distributed above the cutting knife 27. A third torsion arm 63 is provided between the third linkage arm 61 and each cutting knife 27. The upper end of the third torsion arm 63 is hinged to the third linkage arm 61 and the lower end is hinged to the cutting knife 27. One end of the third linkage arm 61 is hinged to the frame 10 and the other end is connected to the fourth motor 62. The fourth motor 62 is used to drive the third linkage arm 61 to rotate so as to synchronously rotate all the cutting knives 27. After the spring is wound to a sufficient length, the cutting knife 27 hinged to the front side of the wire threading die 24 is used to cut the spring wire, and a spring of the required length can be obtained. By driving the third linkage arm 61 to rotate through the fourth motor 62, multiple groups of cutting knives 27 can be driven to rotate synchronously through multiple third torsion arms 63, realizing the synchronous cutting of the springs in multiple groups of spring winding devices 20, thereby integrating the power structures of the cutting knives 27 in multiple groups of spring winding devices 20, achieving the synchronous control of multiple groups of cutting knives 27 by one fourth power mechanism 60, and thus realizing the simplification of the structure and the saving of costs.

[0051] Further, as a specific implementation manner of the spring winding device provided in this embodiment, please refer to Figure 8 and Figure 9 As shown, the above-mentioned fourth power mechanism 60 further includes a fourth torsion arm 64. A third eccentric swing arm 621 is provided at the output end of the fourth motor 62. One end of the fourth torsion arm 64 is hinged to the third eccentric swing arm 621 and the other end is hinged to the third linkage arm 61. When the output shaft of the fourth motor 62 rotates, the third eccentric swing arm 621 makes a circular motion, thereby driving the third linkage arm 61 to swing up and down through the fourth torsion arm 64. During the up and down swing of the second linkage arm 51, the synchronous rotation of all the cutting knives 27 is realized, and the synchronous cutting of the springs in multiple groups of spring winding devices 20 is realized.

[0052] To optimize the function of the device, as a specific implementation manner of the spring winding device provided in this embodiment, please refer to Figure 2 、 Figure 10 and Figure 11 As shown, a wire guiding spring rod 28 is provided on one side of the front end of each wire threading die 24. A spring receiving funnel 29 is provided at the lower end of the wire guiding spring rod 28. The wire guiding spring rod 28 is used to guide the wound spring into the spring receiving funnel 29. During the winding process of the spring, it surrounds the periphery of the upper end of the wire guiding spring rod 28. When the spring is cut by the cutting knife 27, the spring can fall along the wire guiding spring rod 28 into the spring receiving funnel 29. Compared with the related complex structure spring receiving device, this structure is simpler and more direct, the spring receiving effect is stable, and the spring will not fall from the wire guiding spring rod 28 and the spring receiving funnel 29.

[0053] To optimize the function of the device, as a specific implementation manner of the spring winding device provided in this embodiment, please refer toFigure 10 and Figure 11 As shown in Figure 11 , the above-mentioned coil spring device further includes a spring pressing mechanism 70. The spring pressing mechanism 70 includes a fourth linkage arm 71 and a fifth motor 72. The fourth linkage arm 71 is perpendicular to the vertical plate 21 and is distributed above the spring receiving funnel 29. Above each spring receiving funnel 29, a spring pressing plate 73 is hung. An absent slot a is provided on the spring pressing plate 73 and is distributed in alignment with the guide spring rod 28. Both ends of the third linkage arm 61 are slidably connected to the frame 10 through guide rails distributed in the vertical direction; the fourth motor 62 is connected to the third linkage arm 61 to drive the fourth linkage arm 71 to move up and down. When the spring falls into the spring receiving funnel 29, the spring in the spring receiving funnel 29 can be directly compressed by pressing down the spring pressing plate 73, and the absent slot a on the spring pressing plate 73 can just provide a space for accommodating the guide spring rod 28 to prevent the spring pressing plate 73 from touching the guide spring rod 28 during the lifting process; at the same time, the fifth motor 72 is used to drive the fourth linkage arm 71 to slide up and down linearly, so as to drive all the spring pressing plates 73 to lift and lower synchronously, and thus the springs wound by multiple groups of coil spring devices 20 can be compressed synchronously. While ensuring the spring compression function, the structure is further simplified and the cost is saved.

[0054] To optimize the function of the device, as a specific implementation manner of the coil spring device provided in this embodiment, please refer to Figures 10 to 13 As shown in , the above-mentioned coil spring device further includes a spring pushing mechanism 80.

When the spring in the spring receiving funnel 29 is compressed by the spring pressing plate 73, the compressed spring can be pushed along the spring pushing tube 81 to the front end outlet of the spring pushing tube 81 by the spring pushing rod 82, so as to facilitate the conveying and transferring of the compressed spring; at the same time, the sixth motor 84 is used to drive the fifth linkage arm 83 to slide back and forth along the direction of the spring pushing tube 81, so as to drive all the spring pushing rods 82 to push synchronously in their respective spring pushing tubes 81. While ensuring the spring pushing function, the structure is further simplified and the cost is saved.
