[0040] The spring 7 is automatically removed from the machine after the spring swivels 5 and the spring swivels 6 are removed from the machine after the spring swivels 5 are removed.

[0041] A flat material storage box 33 is fixedly connected to the above-mentioned bracket 1. The material storage box 33 is used to store stacked metal wires.

In order to prevent mutual interference between the driving gear 13 and the driven gear 14, the ring gear 11 can be widened so that the two are not on the same annular path when running.

[0046] Specifically, when it is necessary to drive the winding rod 7 to rotate, the motor 12 is started, and the motor 12 drives the ring gear 11 to rotate through the driving gear 13, and the ring gear 11 rotates multiple driven gears 14, and the driven gears 14 drive all the winding rods 7 to rotate synchronously.

[0047] A threaded rod 15 parallel to the winding rod 7 is rotatably mounted on the turntable 3, a guide rod 38 parallel to the threaded rod 15 is fixedly connected to the turntable 3, the threaded rod 15 is connected to the winding rod 7 via a chain drive 16, the chain drive 16 is composed of two sprockets and a chain, wherein a slider 8 slidably connected to the guide rod 38 is threadedly connected to the threaded rod 15, a second telescopic device 9 is fixedly mounted on the slider 8, the second telescopic device 9 is an electric telescopic rod, and a pressure wheel 10 is rotatably mounted on the telescopic end of the second telescopic device 9.

[0048] Specifically, after the metal wire is loaded, the second telescopic device 9 drives the pressure wheel 10 to press on one end of the metal wire, so that one end of the metal wire is pressed tightly against the outer wall of the winding rod 7, and the automatic fixing of the metal wire can be automatically completed. When the winding rod 7 rotates, the rotating winding rod 7 will drive the threaded rod 15 to rotate through the chain drive 16, and the threaded rod 15 will drive the slider 8 to translate along the axis of the winding rod 7, thereby driving the pressure wheel 10 to translate, and the winding rod 7 can automatically complete the winding of the spring.

[0049] Embodiment three:

[0050] Reference Figure 1-Figure 5 , which is basically the same as the second embodiment, and further discloses a specific implementation scheme of the switching unit.

[0051] The above-mentioned switching part includes a worm 17 rotatably connected to the slide 6, a worm wheel 18 is fixedly installed on the outer wall of the rotating shaft 2, and the worm 17 is meshingly connected with the worm wheel 18, wherein a rotating rod 40 is rotatably connected to the slide 6, a passive gear 19 is installed on the rotating rod 40 through a one-way bearing, a rack 20 that cooperates with the passive gear 19 is fixedly installed on the bracket 1, and transmission gears 21 are fixedly installed on the shaft ends of the passive gear 19 and the worm 17, and the two transmission gears 21 are meshingly connected.

[0052] Specifically, after the winding is completed, the pressure wheel 10 is driven away from the spring that has been wound by the second telescopic device 9, and then the slide 6 is driven to translate in the opposite direction by the first telescopic device 5, so that the motor 12 rotates in the opposite direction, and the reversed threaded rod 15 drives the pressure wheel 10 to move in the opposite direction and reset. During this period, the slide 6 drives the passive gear 19 to roll along the surface of the rack 20, and the passive gear 19 drives the rotating rod 40 to rotate.

By replacing the processing station with an unloaded winding rod 7, the winding rod 7 can be automatically replaced to complete the processing of the next spring, preventing the single winding rod 7 from being quickly worn and damaged under continuous high temperature, thereby improving the service life of the winding rod 7, and the downwardly inclined winding rod 7 will tilt the wound spring downward, and the spring will automatically complete the unloading work, which has higher processing efficiency, and the rotating winding rod 7 will also make the spring on the outer wall easier to fall off, and at the same time shake off the iron filings on the outer wall, thereby realizing the automatic cleaning of the winding rod 7. When the passive gear 19 reverses, since the passive gear 19 is installed on the rotating rod 40 through a one-way bearing, the passive gear 19 will idle on the rotating rod 40 instead of driving the rotating rod 40 to reverse.

[0053] Embodiment 4:

[0054] Reference Figure 7 , which is basically the same as the third embodiment, and further, a specific implementation scheme for dissipating heat around the rod 7 is specifically added.

[0055] An inner hole 39 is provided on the end of the winding rod 7 close to the turntable 3, and an exhaust hole 32 connected to the inner hole 39 is provided on the outer wall of the winding rod 7. A blowing part for exhausting air into the inner part is provided in the port of the inner hole 39, and the blowing part includes a circular groove 22 arranged in the port of the inner hole 39, a circular ring 23 is sleeved in the circular groove 22, a fan blade 24 is fixedly mounted on the inner wall of the circular ring 23, and a ball bearing that reduces friction is mounted on the outer wall of the circular ring 23. An anti-slip pattern for increasing friction is provided at one end of the circular groove 22 away from the port of the inner hole 39, and an anti-slip pattern is also provided on the side of the circular ring 23 close to the anti-slip pattern.

[0056] Specifically, when the turntable 3 gradually drives the winding rod 7 to rotate to a horizontal state, the ring 23 will move away from the side with the anti-slip pattern in the circular groove 22, and the friction between the ring 23 and the circular groove 22 is small, so the rotating winding rod 7 will drive the ring 23 to rotate slowly or even not rotate. When the winding rod 7 tilts downward, the ring 23 will rest on the side with the anti-slip pattern, so the rotating winding rod 7 will drive the ring 23 to rotate at a faster speed or even at the same speed as the winding rod 7. At this time, the rotating ring 23 will blow air into the inner hole 39 through the fan blades 24, and the airflow will be discharged through the exhaust hole 32, so the winding rod 7 can be cooled and some iron cuttings on the winding rod 7 and the outer wall of the spring can be blown off.

[0057] Embodiment five:

[0058] Reference Figure 1-Figure 3 as well as Figure 6 , which is basically the same as the fourth embodiment, and further, a specific implementation scheme for making the spring fall in a vertical state is specifically added.

[0059] The bracket 1 is provided with an arc-shaped cover 25 with an opening upward, and a discharge port 26 is provided at the bottom of the arc-shaped cover 25. The bracket 1 is provided with a lifting part for driving the arc-shaped cover 25 to shake up and down, and the lifting part includes a mounting frame 27 fixedly connected to the bracket 1, and a lifting block 28 is slidably connected in the mounting frame 27. The arc-shaped cover 25 is fixedly connected to the lifting block 28, wherein an elastic member 29 is installed between the lifting block 28 and the inner top of the mounting frame 27, and the elastic member 29 can be a spring. A top rod 30 that is attached to the outer wall of the turntable 3 is fixedly connected to the arc-shaped cover 25, and a plurality of equally spaced protrusions 31 are fixedly installed on the outer wall of the turntable 3. The number of the protrusions 31 is 20-40, and the preferred number in this application is 28.

[0060] When the rod 7 is tilted downward, the end of the rod 7 will be blocked by the arc cover 25, so the downwardly tilted rod 7 will not pour out the spring on the outer wall, and when the rod 7 is completely vertical downward, that is, toward the discharge port 26, the downwardly vertical rod 7 will pour out the spring on the outer wall, so that the spring will fall vertically into the cooling pool, so that the fallen spring can buffer the impact force by itself and is not easily deformed. During the rotation of the turntable 3, the rotating turntable 3 will drive the multiple protrusions 31 to press the push rod 30 in sequence. When the push rod 30 is pressed, it will drive the arc cover 25 to move downward. When the push rod 30 is not pressed, the elastic member 29 will drive the lifting block 28 and the arc cover 25 to move upward and reset. Therefore, under the action of the multiple protrusions 31, the arc cover 25 will vibrate up and down, so that the spring on the outer wall of the rod 7 can be vibrated, so that the iron filings on the spring and the outer wall of the rod 7 can be shaken off, which is convenient for the subsequent cleaning of the spring.

[0065] Step 4: Make the processed spring fall downward from the outer wall of the winding rod 7;

[0066] Step 5: Repeat steps 1 to 4 above.

[0067] When the spring winding equipment for spring production is used, the metal wires for processing springs are stacked and placed in a storage box 33, and then a metal wire at the bottom of the storage box 33 is transported toward the discharge hole 34 by the first conveying wheel 36. During the transportation, the metal wire is heated by the heating coil 35, and then the metal wire is transported to one of the transversely arranged winding rods 7 by the second conveying wheel 37, thereby completing the automatic feeding of the metal wire, indirectly improving the processing efficiency of the spring and reducing the workload of the staff.

[0068] After the metal wire is loaded, the second telescopic device 9 drives the pressure wheel 10 to press on one end of the metal wire, so that one end of the metal wire is pressed tightly against the outer wall of the winding rod 7, and then the motor 12 and the first telescopic device 5 are started at the same time. The motor 12 will drive the ring gear 11 to rotate through the driving gear 13, and the ring gear 11 will rotate multiple driven gears 14, and the driven gears 14 will drive the winding rod 7 to rotate, and the first telescopic device 5 will drive the slide 6 to move horizontally, and the slide 6 will drive the turntable 3 to move horizontally synchronously, and the turntable 3 can drive the rotating winding rod 7 to move horizontally, and the rotating winding rod 7 will drive the threaded rod 15 to rotate through the chain drive 16, and the threaded rod 15 will drive the slider 8 to translate along the axis of the winding rod 7, thereby driving the pressure wheel 10 to translate, and the winding rod 7 can automatically complete the winding of the spring.

[0069] After the winding is completed, the pressure wheel 10 is driven away from the wound spring by the second telescopic device 9, and then the slide 6 is driven to translate in the opposite direction by the first telescopic device 5, so that the motor 12 rotates in the opposite direction, and the reversed threaded rod 15 drives the pressure wheel 10 to move in the opposite direction and reset. During this period, the slide 6 drives the passive gear 19 to roll along the surface of the rack 20, and the passive gear 19 drives the rotating rod 40 to rotate. The rotating rod 40 drives the worm 17 to rotate through two mutually meshing transmission gears 21, and the worm 17 drives the rotating shaft 2 to rotate through the worm wheel 18, and the rotating shaft 2 will rotate. The turntable 3 is driven to rotate, and the turntable 3 can drive the originally horizontal winding rod 7 to tilt downward, and another unloaded winding rod 7 can replace the processing station, so that the winding rod 7 can be automatically replaced to complete the processing of the next spring, thereby preventing the single winding rod 7 from being quickly worn and damaged under continuous high temperature, thereby improving the service life of the winding rod 7, and the downwardly tilted winding rod 7 will tilt the wound spring downward, and the spring will automatically complete the unloading work, so that the processing efficiency is higher, and the rotating winding rod 7 will also make the spring on the outer wall easier to fall off, and at the same time make the iron filings on the outer wall shake off, thereby realizing the automatic cleaning of the winding rod 7.
