[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-7 As shown, the present invention has the following specific embodiments.

[0033] Example 1

[0034] An S-spring rolling device includes an S-spring 6 and further includes:

[0035] Conveyor 1, a support plate 2 is fixedly connected to one side of the support of conveyor 1, a mounting slide groove 201 is provided in the support plate 2, two connecting members are symmetrically slidably installed in the mounting slide groove 201, and the connecting members include a connecting block 203 and two sliders 205, the two sliders 205 are respectively fixedly connected to the two ends of the connecting block 203, and a clamping block 206 is fixedly connected to one side of the slider 205;

[0036] The storage mechanism 3 is provided with two groups, and the storage mechanism 3 includes an L-shaped clamping plate 301 and a second stud 305. The front and rear surfaces of the L-shaped clamping plate 301 are provided with a limited slot 302, and the limited slot 302 is slidably matched with the clamping block 206. A second threaded sleeve 304 is embedded and installed on the L-shaped clamping plate 301, and the second threaded sleeve 304 is threadedly matched with the second stud 305. The lower end of the second stud 305 is fixedly connected with a clamping column 306;

[0037] The unloading mechanism 4 includes a slide rail 401 and a push column 409. A limited slide groove 402 is provided on the front of the slide rail 401. A limited slider 405 is slidably installed in the limited slide groove 402. A threaded mounting hole 407 is provided on the front of the limited slider 405. A threaded mounting column 408 is threadedly installed in the threaded mounting hole 407. The threaded mounting column 408 is rotatably connected to the push column 409.

[0038] The rolling mechanism 5 includes a support base 501 and a rolling sleeve 504. A second motor 502 is fixedly connected to one side of the support base 501. A rotating disk 503 is fixedly connected to the output end of the second motor 502. The rolling sleeve 504 is fixedly connected to the rotating disk 503. A clamping mechanism is arranged on one side of the rotating disk 503.

[0039] In this embodiment, a limiting rod can be formed by the second stud 305 and the clamping column 306. The limiting rod cooperates with the L-shaped clamping plate 301. The limiting rod is clamped at the bending part of the S-spring 6. The L-shaped clamping plate 301 is against the outside to limit the S-spring 6. Then, the S-springs 6 are neatly stacked together and are located on the conveyor belt of the conveyor 1. Figure 1As shown, the limiting card slot 302 and the card block 206 are slidably matched, thereby clamping the storage mechanism 3 on one side of the support plate 2, and the lower end of the L-shaped clamping plate 301 contacts the upper surface of the conveyor 1 bracket, and the second stud 305 is threadedly matched with the second threaded sleeve 304. Rotating the second stud 305 can drive the clamping column 306 to move up, so that a certain gap is left between the clamping column 306 and the conveying belt of the conveyor 1. This gap is greater than the height of an S-spring 6 and less than the height of two S-springs 6 stacked together. After starting the conveyor 1, the S-spring 6 at the bottom contacts the conveying belt of the conveyor 1, and the conveyor 1 will drive the S-spring 6 at the bottom to move and continuously approach the rolling mechanism 5, while the S-spring 6 at the top will be restricted by the clamping column 306 to prevent the S-spring 6 at the top from being driven by the S-spring 6 at the bottom. When the S-spring 6 at the bottom is driven by the conveyor 1 to the rolling mechanism 5, the clamping mechanism can be used to clamp the front end of the S-spring 6 at the rolling mechanism The surface of the round sleeve 504 is then driven by the second motor 502 to drive the rotating disk 503 to rotate. The rotation of the rotating disk 503 will drive the clamping mechanism and the rolling sleeve 504 to rotate synchronously. Since one end of the S-spring 6 is clamped on the surface of the rolling sleeve 504, the S-spring 6 is wound in a circle. After the winding is completed, the limit slider 405 in the unloading mechanism 4 is used to drive the threaded mounting column 408 to move. The movement of the threaded mounting column 408 will drive the push column 409 to move. The push column 409 is sleeved on the rolling sleeve 504, and then the push column 409 will interfere with the rolled S-spring 6. As the push column 409 moves, the push column 409 will scrape off the S-spring 6 on the rolling sleeve 504, completing automatic unloading and realizing fully automatic S-spring 6 rolling and bending operation. First of all, there is no need to manually place the S-springs 6 one by one, which reduces the use of manpower and reduces the chance of contact between staff and machines, avoiding injuries to operators.

[0040] Example 2

[0041] like Figure 1 , 3 As shown in , 4, a push bar 101 is fixedly connected to the surface of the conveyor belt of the conveyor 1, a bidirectional threaded shaft 202 is rotatably installed in the mounting groove 201, a first threaded sleeve 204 is embedded and installed in the connecting block 203, the first threaded sleeve 204 is threadedly matched with the bidirectional threaded shaft 202, the height of the push bar 101 is lower than the diameter of the S spring 6, a knob 307 is fixedly connected to the upper end of the second stud 305, a plug-in groove 303 is opened in the limiting slot 302, a bottom support plug-in plate 308 is plugged in the plug-in groove 303, one end of the bottom support plug-in plate 308 is fixedly connected to a limiting ring 309, the limiting ring 309 cooperates with the clamping column 306, and a pull rope 310 is fixedly connected to the outer wall of the limiting ring 309.

[0042] In this embodiment, by starting the conveyor 1, the push bar 101 will rotate together with the conveyor belt. The push bar 101 is slightly lower than the diameter of an S-spring 6 and the height of a single S-spring 6 to avoid interference between the push bar 101 and the S-spring 6 piled on top. The push bar 101 presses against the rear end of the S-spring 6 to push the S-spring 6 forward, thereby assisting the conveyor 1 to drive the lowest S-spring 6 to move. The knob 307 can be used to drive the second stud 305 to rotate. The rotation of the second stud 305 will drive the clamping column 306 to move, thereby adjusting the distance between the lower end of the clamping column 306 and the conveyor belt of the conveyor 1. The storage mechanism 3 can be removed as a whole and inverted, so that the S-spring 6 can be clamped in the gap between the clamping column 306 and the L-shaped clamping plate 301. Then, the bottom support plug plate 308 is plugged into the plug-in slot 303. The second stud 305 is rotated to drive the clamping column 3 After the second screw 305 is rotated to bring the clamping column 306 out of the limiting collar 309, the restriction on the bottom support plate 308 is released, and the bottom support plate 308 can be pulled out of the plug slot 303 by pulling the pull rope 310. At this time, the S-spring 6 is not blocked by the bottom support plate 308 and will naturally fall onto the conveyor belt of the conveyor 1 by gravity. Multiple sets of storage mechanisms 3 can be configured to fix the S-spring 6 in the storage mechanism 3 in advance. After the S-spring 6 is consumed on the device, the storage mechanism 3 can be replaced to reduce the time for placing the stacked S-spring 6, reduce downtime, and improve processing efficiency.

[0043] Example 3

[0044] like Figure 3 , 6 As shown, a fourth motor 511 is embedded in the rotating disk 503, a dovetail groove 509 is provided on one side of the rotating disk 503, a fourth threaded column 510 is rotatably installed in the dovetail groove 509, the fourth threaded column 510 is fixedly connected to the output end of the fourth motor 511 and the fourth threaded column 510, the clamping mechanism includes a dovetail slider 513 and a clamping plate 512, the dovetail slider 513 is slidably installed in the dovetail groove 509, a fourth threaded through hole 514 is provided in the dovetail slider 513, the fourth threaded through hole 514 is threadably matched with the fourth threaded column 510, the clamping plate 512 is fixedly connected to the dovetail slider 513, and a position sensor 515 is fixedly connected to the clamping plate 512.

[0045] In this embodiment, the fourth threaded column 510 can be driven to rotate by starting the fourth motor 511, and the fourth threaded column 510 is threadedly matched with the fourth threaded through hole 514, so that the rotation of the fourth threaded column 510 can drive the dovetail slider 513 to move, and the movement of the dovetail slider 513 can drive the clamping plate 512 to move, and the clamping plate 512 moves close to the rolling sleeve 504, so as to clamp the S spring 6 located between the clamping plate 512 and the rolling sleeve 504, and the position sensor 515 is used to detect the position of the S spring 6. When the front end of the S spring 6 passes through the position sensor 515, a signal will be sent to the conveyor 1, and the conveyor 1 will be paused to continue to convey the S spring 6, so that the clamping plate 512 can clamp and fix the end of the S spring 6. A conductive slip ring is sleeved on the connecting shaft between the rotating disk 503 and the second motor 502, so as to transmit electricity and control signals to the rotating rotating disk 503 to provide power for the fourth motor 511. This is a relatively common structure currently available, and is not shown in the figure.

[0046] Example 4

[0047] like Figure 1 , 5 As shown in , 6, a fixing frame 505 is fixedly connected to the inner wall of the rolling sleeve 504, a fixing threaded hole 508 is opened at the center of one side of the rotating disk 503, a fixing through hole 506 is opened in the fixing frame 505, a fixing bolt 507 is arranged in the fixing through hole 506, and the fixing bolt 507 is threadedly matched with the fixing threaded hole 508, a third screw rod 403 is rotatably installed in the limiting slide groove 402, a first motor 404 is fixedly connected to the back of the slide rail 401, and the output end of the first motor 404 is fixedly connected to the third screw rod 403, a threaded through hole 406 is opened in the limiting slider 405, and the threaded through hole 406 is threadedly matched with the third screw rod 403.

[0048] In this embodiment, the fixing bolt 507 is passed through the fixing through hole 506 and screwed into the fixing threaded hole 508, thereby fixing the rolling sleeve 504 on the rotating disk 503. After the fixing bolt 507 is unscrewed, the rolling sleeve 504 can be directly removed. When the coil bending angle of the S-spring 6 needs to be changed, the rolling sleeve 504 with different diameters can be selected. When the diameter of the rolling sleeve 504 changes, the push post 409 also needs to be replaced with a matching one. The threaded mounting post 408 is rotatably connected to the push post 409, so that the threaded mounting post 408 can rotate independently. 08 can be unscrewed from the inside of the threaded mounting hole 407, and the push column 409 can be removed from the limit slider 405, so as to facilitate the replacement of the push column 409 with a suitable inner diameter. Starting the first motor 404 can drive the third screw 403 to rotate, and the third screw 403 is threadedly matched with the threaded through hole 406, so that the rotation of the third screw 403 can drive the limit slider 405 to move, and the limit slider 405 moves through the threaded mounting column 408 to drive the push column 409 to move, and the S-spring 6 on the rolled sleeve 504 is pushed down by the push column 409, and then the first motor 404 is started in reverse to drive the push column 409 to reset.

[0049] The working principle and use process of the present invention:

[0050] Step 1: The S spring 6 needs to be clamped inside the storage mechanism 3. According to the distance between the two storage mechanisms 3, the bidirectional threaded shaft 202 is rotated to drive the connecting block 203 to move. The movement of the connecting block 203 can drive the slider 205 to move, thereby adjusting the distance between the two connecting members. The storage mechanism 3 is clamped on the connecting member by slidingly cooperating with the clamping block 206 and the limiting clamping groove 302. The second stud 305 is rotated to drive the clamping column 306 to move, and the height of the clamping column 306 is adjusted so that the distance between the lower end of the clamping column 306 and the conveyor belt of the conveyor 1 is slightly larger than the height of a single S spring 6.

[0051] Step 2: Start the conveyor 1 to rotate the conveyor belt and the push bar 101. The push bar 101 abuts against the rear end of the lowest S-spring 6. The conveyor belt can drive the lowest S-spring 6 forward, and the upper stacked S-spring 6 will be stuck by the clamping column 306. Then, only the lowest S-spring 6 will be driven. When the front end of the lowest S-spring 6 moves between the clamping plate 512 and the rolling sleeve 504, the position sensor 515 will detect that the S-spring 6 has passed through, and a signal will be sent to stop the conveyor 1.

[0052] Step 3: Start the fourth motor 511 to drive the fourth threaded column 510 to rotate. The rotation of the fourth threaded column 510 will drive the dovetail slider 513 to move upward. The upward movement of the dovetail slider 513 will drive the clamping plate 512 to move upward. The clamping plate 512 will continue to approach the rolling sleeve 504, thereby clamping and fixing the front end of the S spring 6 on the surface of the rolling sleeve 504. Start the second motor 502 to drive the rotating disk 503 to rotate. The rotation of the rotating disk 503 will drive the rolling sleeve 504 to rotate. The rotation of the rolling sleeve 504 will drive the S spring 6 to wrap around the surface of the rolling sleeve 504, thereby realizing the circle bending of the S spring 6.

[0053] Step 4: Start the first motor 404 to drive the third screw 403 to rotate. The rotation of the third screw 403 will drive the limit slider 405 to move. The movement of the limit slider 405 will use the threaded mounting column 408 to drive the push column 409 to move. The push column 409 is sleeved on the rolling sleeve 504. Then, the movement of the push column 409 will push down the S spring 6 wound on the surface of the rolling sleeve 504, and then the first motor 404 is reversely started to drive the push column 409 to reset;

[0054] Repeat the above steps 2, 3 and 4 to continuously and automatically perform the circle bending operation on the S spring 6.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
