The inlet is connected, a transmission gear 103 is rotatably connected to the processing chamber 1, and a sliding sleeve 102 is connected to the rotating shaft of the transmission gear 103. When the sliding sleeve 102 is sleeved on the spline on the rotating shaft of the transmission gear 103, the external power drives the transmission gear 103 to rotate through the sliding sleeve 102. A sliding support plate 302 is slidably connected in the processing chamber 1, and a support cylinder 301 is slidably connected in the sliding support plate 302 on the front side, and a rotating cylinder 3 is slidably connected in the sliding support plate 302 on the rear side.

[0035] The part where the tapping device is located in the processing chamber 1 is the front, and the cut steel sleeves to be processed are stacked and placed in the storage box 101, and the steel bars in the storage box 101 fall on the swing bracket 403, and the swing bracket 403 provides support for the steel sleeves to be processed, and then the sliding sleeve 102 and the transmission gear 103 are driven to rotate by external power, and when the transmission gear 103 rotates, the rotating cylinder 3 is driven to move through the moving mechanism, and the sliding support plate 302 slides along the processing chamber 1, and when the rotating cylinder 3 moves, the rear bracket 304 slides along the inner bottom plate 1001 accordingly, and during the movement of the rotating cylinder 3 and the supporting cylinder 301, the front bracket 303 provides support for the supporting cylinder 301, and the rear bracket 304 provides support for the rotating cylinder 3, so as to prevent the rotating cylinder 3 and the supporting cylinder 301 from being slid. 301 is skewed during movement. When the front bracket 303 moves, the rear bracket 304 and the support cylinder 301 are pushed to move through the fixed ring 3051. During the movement of the rotating cylinder 3, the compression spring 306 cooperates with the support cylinder 301 to clamp the steel sleeve to be processed. The compression spring 306 presses the support cylinder 301 on the steel sleeve to be processed, and the rotating cylinder 3 drives the steel sleeve to be processed to rotate. When the rotating cylinder 3 pushes the steel sleeve to be processed through the peeling device, the peeling device peels off the oxidized outer skin of the steel sleeve to be processed, and then the rotating cylinder 3 continues to push the steel sleeve to be processed to the tapping device, and the tapping sleeve processes the internal thread in the steel sleeve to be processed, thereby realizing the function of processing threads in the steel sleeve to be processed.

[0036] Embodiment 2: On the basis of Embodiment 1, the moving mechanism includes a rotating gear 104, a transmission gear rod 2, a threaded rod 201, a moving gear 202, a connecting plate 2021 and a rotating gear 203. The rotating gear 104 is rotatably connected in the processing chamber 1. The rotating gear 104 is coaxially fixed to the transmission gear rod 2. The threaded rod 201 is fixed in the processing chamber 1. The moving gear 202 is threadedly connected to the threaded rod 201. The moving gear 202 is meshed with the transmission gear rod 2. The transmission gear rod 2 drives the moving gear 202 to rotate. When the moving gear 202 rotates, it moves along the threaded rod 201. The rotating cylinder 3 is fixed with a rotating gear 203. The moving gear 202 is meshed with the rotating gear 203. The moving gear 202 and the rotating gear 203 are connected through the connecting plate 2021. The moving gear 202 drives the rotating gear 203 and the rotating cylinder 3 to move through the connecting plate 2021.

[0037] When the sliding sleeve 102 drives the transmission gear 103 to rotate, the transmission gear 103 drives the transmission gear rod 2 to rotate through the rotating gear 104, and the transmission gear rod 2 drives the moving gear 202 to rotate. Since the threaded rod 201 itself is fixed and cannot rotate, the moving gear 202 moves forward along the threaded rod 201 when it rotates. When the moving gear 202 moves, it pushes the rotating gear 203 to move forward through the connecting plate 2021, and the moving gear 202 is meshed with the rotating gear 203. When the rotating gear 203 moves, it drives the rotating cylinder 3 to move forward and rotate.

[0038] The peeling device includes a fixed frame 6, a peeling knife 601 and a peeling spring 602. The fixed frame 6 is fixedly connected to the processing chamber 1, and the peeling knife 601 is slidably connected to the fixed frame 6. The peeling knife 601 and the fixed frame 6 are connected through the peeling spring 602. One end of the peeling spring 602 is fixedly connected to the peeling knife 601, and the other end is fixedly connected to the fixed frame 6.

[0039] When the rotating cylinder 3 pushes the steel sleeve to be processed forward, the peeling knife 601 contacts the outer wall of the steel sleeve to be processed. As the rotating cylinder 3 pushes the steel sleeve to be processed forward and rotates, the peeling knife 601 removes the oxidized part of the outer wall of the steel sleeve to be processed.

[0040] The tapping device includes a tap 5, a sliding plate 501, a reset spring 502 and a reversing assembly. The tap 5 is fixedly connected in the processing chamber 1. The tap 5 processes the internal thread in the sleeve. The sliding plate 501 is slidably connected in the tap 5. A reset spring 502 is connected between the sliding plate 501 and the tap 5. One end of the reset spring 502 is fixedly connected to the sliding plate 501, and the other end is fixedly connected to the tap 5. After the internal thread processing is completed, the reset spring 502 pushes the support cylinder 301 to move and reset through the sliding plate 501. The reversing assembly is installed in the processing chamber 1, and the reversing assembly is used to adjust the rotation direction of the rotating cylinder 3.

[0041] During the process of the rotating cylinder 3 pushing the steel sleeve to be processed to move toward the tap 5, the supporting cylinder 301 will not contact the tap 5, and the steel sleeve to be processed is gradually sleeved outside the tap 5, and the steel sleeve to be processed is driven to rotate by the rotating cylinder 3 during the movement, so that the tap 5 opens an internal thread in the steel sleeve to be processed. During the movement of the steel sleeve to be processed, the supporting cylinder 301 pushes the sliding plate 501 to slide along the tap 5 and compresses the reset spring 502. When the internal thread of the steel sleeve to be processed is completed, the reversing assembly changes the rotation direction of the transmission gear rod 2. At this time, the moving gear 202 drives the rotating gear 203 to move away from the tap 5 through the connecting plate 2021, and the rotating cylinder 3 moves and resets accordingly. The reset spring 502 pushes the supporting cylinder 301 to move and reset through the sliding plate 501, and the processed steel sleeve moves and resets accordingly.

[0042] The reversing assembly includes a first reversing gear 105, a second reversing gear 1051, a third reversing gear 1052, a moving frame 503, a connecting ring 5031, a sliding connecting rod 504, a tension spring 5041, a connecting ring 5042, a sliding support frame 505 and a connecting spring 507. The first reversing gear 105, the second reversing gear 1051 and the third reversing gear 1052 are rotatably connected in the processing chamber 1, and the moving frame 503 is slidably connected in the tap 5. The moving frame 503 and the tap 5 are connected through a connecting spring 507.

A sliding connecting rod 504 is fixedly connected to the sliding plate 501. One end of the sliding connecting rod 504 away from the sliding plate 501 passes through the movable frame 503 and is slidably connected thereto. A sliding support frame 505 is slidably connected to the sliding connecting rod 504. A connecting ring 5042 is fixedly connected to the sliding connecting rod 504. The connecting ring 5042 and the sliding support frame 505 are connected via a tension spring 5041. One end of the tension spring 5041 is fixedly connected to the connecting ring 5042, and the other end of the tension spring 5041 is fixedly connected to the sliding support frame 505.

[0043] When the support cylinder 301 pushes the sliding plate 501 to slide along the tap 5, the sliding connecting rod 504 moves with the sliding plate 501. When the sliding connecting rod 504 moves, the tension spring 5041 first returns to its original state. After the tension spring 5041 returns to its original state, it pushes the sliding support frame 505 to move toward the moving frame 503. When the sliding support frame 505 contacts the moving frame 503, the moving frame 503 is blocked by the connecting spring 507 and cannot move. As the sliding plate 501 continues to move, the sliding connecting rod 504 continues to move with it and compresses the tension spring 5041. When the elastic force of the tension spring 5041 is greater than the elastic force of the connecting spring 507, the sliding plate 501 is pushed by the tension spring 5041 and the sliding support frame 505. The moving frame 503 slides along the tap 5 and compresses the connecting spring 507. When the internal thread of the steel bar sleeve to be processed is completed, the moving frame 503 moves to pull the sliding sleeve 102 to move toward the first reversing gear 105 through the connecting ring 5031. The sliding sleeve 102 is sleeved on the spline shaft of the first reversing gear 105. At this time, the sliding sleeve 102 will drive the first reversing gear 105 to rotate. The first reversing gear 105 drives the transmission gear rod 2 to rotate in the opposite direction through the second reversing gear 1051 and the third reversing gear 1052 to change the rotation direction of the moving gear 202, so that the moving gear 202 moves along the threaded rod 201 in the direction away from the tap 5 and resets.

[0044] Embodiment 3: Based on Embodiment 2, it also includes a supporting mechanism for preventing the steel sleeve in the material storage box 101 from falling downward during processing, the supporting mechanism includes a sliding baffle 1011, a fixed block 1012 and a material blocking spring 1013, the material storage box 101 is slidably connected with the sliding baffle 1011, and the material blocking spring 1013 is connected between the sliding baffle 1011 and the processing bin 1, one end of the material blocking spring 1013 is fixedly connected to the sliding baffle 1011, and the other end is fixedly connected to the processing bin 1, the bottom surface of the sliding baffle 1011 is fixedly connected to the fixed block 1012, and the rotating cylinder 3 pushes the sliding baffle 1011 to slide along the bottom of the material storage box 101 through the fixed block 1012.

[0045] When the rotating drum 3 pushes the steel sleeve to be processed to move toward the tap 5, the blocking spring 1013 pushes the sliding baffle 1011 to slide along the storage box 101 and blocks the outlet at its bottom, so as to provide support for the steel sleeve to be processed in the storage box 101.

[0046] It also includes a limiting mechanism for limiting the position of the peeling knife 601, the limiting mechanism includes a wedge rod 5032, a sliding stopper 506 and a blocking spring 5061, the wedge rod 5032 is fixedly connected to the movable frame 503, the end of the wedge rod 5032 away from the movable frame 503 is connected to the peeling knife 601, the sliding stopper 506 is slidably connected in the tap 5, and a blocking spring 5061 is connected between the sliding stopper 506 and the tap 5, one end of the blocking spring 5061 is fixedly connected to the sliding stopper 506, and the other end is fixedly connected to the tap 5.

[0047] When the movable frame 503 is in the original position, the wedge rod 5032 contacts the peeling knife 601 and limits its position. When the sliding plate 501 pushes the movable frame 503 to move along the tap 5 through the sliding connecting rod 504, the tension spring 5041 and the sliding support frame 505, the movable frame 503 drives the wedge rod 5032 to move, so that the wedge rod 5032 is out of contact with the peeling knife 601, and the peeling spring 602 pushes the peeling knife 601 to slide along the fixed frame 6 in the direction away from the steel bar sleeve. At this time, the sliding stopper 506 is out of contact with the movable frame 503, and the blocking spring 5061 pushes the sliding stopper 506 to move along the tap 5 and limit the position of the movable frame 503. During the process of resetting the processed steel bar sleeve, the peeling knife 601 will no longer contact the processed steel bar sleeve. When the reset spring 502 pushes the sliding plate 501 to reset, the sliding plate 501 pulls the sliding connecting rod 504 to move and reset. 5042 moves and resets accordingly. During the reset process of the sliding link 504, since the sliding support frame 505 is restricted by the sliding block 506, the tension spring 5041 returns to its original state first. As the sliding link 504 and the connecting ring 5042 continue to move, the distance between the connecting ring 5042 and the sliding support frame 505 gradually increases, and the tension spring 5041 is stretched. When the tension of the tension spring 5041 is large enough, the tension spring 5041 opens the sliding block 506 through the sliding support frame 505 and compresses the blocking spring 5061. When the sliding plate 501 is reset, the sliding support frame 505 just completely opens the sliding block 506. At this time, the connecting spring 507 pushes the moving frame 503 to slide and reset along the tap 5. The moving frame 503 pushes the peeling knife 601 to slide and reset along the fixed frame 6 through the wedge rod 5032. The connecting ring 5031 simultaneously pushes the sliding sleeve 102 to move and makes it sleeved on the rotating shaft of the transmission gear 103.

[0048] The discharging mechanism also includes a discharging mechanism for sending out the processed steel bar sleeve, which includes a fixed pressure rod 307, a fixed rod 4, a fixed rack 401, a discharging gear 402, a discharging stop frame 406 and a discharging spring 407. The fixed guide rod 305 is fixedly connected to the fixed pressure rod 307 at one end away from the rear bracket 304. The rear bracket 304 is fixedly connected to the fixed rod 4, and the fixed rack 401 is fixedly connected to the fixed rod 4. The discharging gear 402 is coaxially fixed to the swing bracket 403, and the discharging gear 402 is meshed with the fixed rack 401. The discharging stop frame 406 is fixedly connected to the inner bottom plate 1001, and a discharging spring 407 is connected between the discharging stop frame 406 and the inner bottom plate 1001. One end of the discharging spring 407 is fixedly connected to the discharging stop frame 406, and the other end is fixedly connected to the inner bottom plate 1001.

[0049] When the front bracket 303 and the rear bracket 304 slide along the inner bottom plate 1001 toward the tap 5, the front bracket 303 contacts the inclined surface of the discharge stop frame 406 and pushes it to slide downward. At this time, the discharge spring 407 is compressed. When the front bracket 303 passes the discharge stop frame 406, the discharge spring 407 pushes the discharge stop frame 406 to slide and reset. The corresponding position of the rear bracket 304 and the discharge stop frame 406 arches upward, and the rear bracket 304 does not contact the discharge stop frame 406. When the front bracket 303 and the rear bracket 304 slide along the inner bottom plate 1001 in the direction away from the tap 5, the front bracket 303 is blocked by the discharge stop frame 406, and the support cylinder 301 is also restricted and cannot move. At this time, the rotating cylinder 3 and the rear bracket 304 continue to move backward, and the fixed rod 4 and the fixed rack 401 move accordingly. When the rear bracket 304 continues to move, the fixed guide rod 305 continues to drive the fixed pressure rod 307 to move, and the fixed pressure rod 307 pushes the discharging stop frame 406 to slide downward, and the discharging stop frame 406 no longer restricts the position of the front bracket 303. At this time, the reset spring 502 pushes the support tube 301 and the front bracket 303 to move and reset through the sliding plate 501, and the feeding gear 402 moves accordingly and drives the swing bracket 403 to swing upward and reset under the action of the fixed rack 401.

[0050] It also includes an adjustment mechanism for adjusting the distance between the rotating cylinder 3 and the supporting cylinder 301, the adjustment mechanism includes a wedge-shaped stopper 404 and a limit spring 405, the wedge-shaped stopper 404 is slidably connected to the inner bottom plate 1001, the limit spring 405 is connected between the wedge-shaped stopper 404 and the inner bottom plate 1001, one end of the limit spring 405 is fixed to the wedge-shaped stopper 404, and the other end is fixed to the inner bottom plate 1001.

[0051] When the rotating cylinder 3 and the supporting cylinder 301 move and reset, the front bracket 303 is restricted by the wedge-shaped block 404 and cannot be completely reset. The compression spring 306 between the front bracket 303 and the fixed guide rod 305 is compressed. At this time, the distance between the rotating cylinder 3 and the supporting cylinder 301 increases, so that the steel sleeve to be processed can fall on the swinging bracket 403. When the rotating cylinder 3 pushes the steel sleeve to be processed to move toward the tap 5, the front bracket 303 and the supporting cylinder 301 remain stationary. During the process of the rear bracket 304 pushing the fixed guide rod 305 to move and restoring the compression spring 306, the rotating cylinder 3 pushes the steel sleeve to be processed into the supporting cylinder 301. When the fixing ring 3051 contacts the front bracket 303, the front end of the steel sleeve to be processed just contacts the inner wall of the supporting cylinder 301.

[0052] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
