[0035] During processing, the workpiece is placed on the outside of the rotating cylinder 2, and then the control cylinder 211 is started. The control cylinder 211 can push the rotating disk 212 to move in the direction close to the workpiece. During the movement of the rotating disk 212, the tightening mechanism can be driven to operate and push the sliding tightening block 201 to slide outside the rotating cylinder 2 and tighten the workpiece. Then the rotating motor 102 is started again. The rotating motor 102 can drive the rotating cylinder 2 to rotate through the first belt transmission member 103.

During the rotation of the workpiece, the trimming mechanism operates, and the propulsion assembly in the trimming mechanism drives the L-shaped slide bar 3 and the cutter 301 to move toward the workpiece and cut off the excess material outside the workpiece. After the cutting is completed, the pressure coil 510 in the curling mechanism will contact the workpiece and perform curling processing on the edge of the workpiece, thereby realizing the function of automatically cutting off the excess material outside the workpiece and performing curling.

[0036] Embodiment 2: Based on embodiment 1, Figure 3-Figure 6As shown, the tightening mechanism includes a reset spring 202, a sliding block 203, a return spring 204, a support shaft 205 and a pushing assembly. The reset spring 202 is arranged between the sliding tightening block 201 and the rotating cylinder 2. The reset spring 202 is used to push the sliding tightening block 201 to slide into the rotating cylinder 2. The sliding block 203 is slidingly arranged in the rotating cylinder 2.

[0037] When the control cylinder 211 pushes the rotating disk 212 to move, it will drive the pushing assembly to move. Under the push of the pushing assembly, the sliding block 203 will drive the support shaft 205 to move and compress the return spring 204.

[0038] like Figure 4-Figure 6 As shown, the pushing assembly includes a connecting ring 206, a connecting block 207, a moving frame 208, a missing gear 209, a cam 210, a connecting rod 213 and a moving rack 214. The connecting ring 206 is connected to the sliding block 203, the connecting block 207 is slidably set on the connecting ring 206, the moving frame 208 is fixedly connected to the connecting block 207, the missing gear 209 is rotatably set on the side bracket 101, the cam 210 is fixedly connected to the missing gear 209, the moving frame 208 is provided with a slotted hole, a round rod is provided between the cam 210, and the round rod passes through the moving frame The connecting rod 213 is fixedly connected to the telescopic rod of the control cylinder 211, and the movable rack 214 is fixedly connected to the connecting rod 213. The control cylinder 211 can push the movable rack 214 to move through the connecting rod 213. The movable rack 214 is meshed with the missing gear 209. When the movable rack 214 moves, it can drive the cam 210 to rotate through the missing gear 209. When the cam 210 rotates, it can drive the movable frame 208 to move through the round rod, and at the same time drive the sliding block 203 to move in the rotating cylinder 2 through the connecting block 207 and the connecting ring 206.

[0039] When the control cylinder 211 pushes the rotating disk 212 to move in the direction of the rotating cylinder 2, the connecting rod 213 and the moving rack 214 move accordingly and drive the missing gear 209 to rotate. When the missing gear 209 rotates, it can drive the moving frame 208 to move in the direction close to the rotating disk 212 through the cam 210. The moving frame 208 can drive the connecting ring 206 to move in the direction close to the rotating disk 212 through the connecting block 207, so that the sliding block 203 pushes the supporting shaft 205 to slide the sliding support block 201 out of the rotating cylinder 2. When the control cylinder 211 drives the rotating disk 212 to move and reset, the connecting rod 213 and the moving rack 214 are reset accordingly, and the missing gear 209 rotates in the opposite direction and drives the moving frame 208 to move and reset in the direction away from the rotating disk 212 through the cam 210. The connecting block 207 and the connecting ring 206 are reset accordingly, thereby realizing the function of pushing the sliding support block 201 to slide along the rotating cylinder 2 to tighten or loosen the workpiece.

[0040] Embodiment 3: Based on embodiment 2, Figure 7-Figure 11 As shown, the trimming mechanism includes a propulsion component and a blocking component. The propulsion component is used to push the L-shaped slide bar 3 and the cutter 301 to move toward the workpiece, and the blocking component is used to prevent the cutter 301 from contacting the workpiece in advance to avoid damage to the cutter 301. When the missing gear 209 rotates, it can drive the propulsion component to operate, and the propulsion component can push the L-shaped slide bar 3 and the cutter 301 to move toward the workpiece. When the connecting ring 206 rotates, it can drive the blocking component to operate to release the restriction on the L-shaped slide bar 3.

[0041] like Figure 7-Figure 9 As shown, the propulsion assembly includes a rotating shaft 302, a rotating rod 303, a second belt transmission member 304, an L-shaped sliding rod 305, a connecting push rod 306 and a pushing spring 307. The rotating shaft 302 is rotatably connected to the workbench 1, and the rotating rod 303 is rotatably arranged in the workbench 1. The second belt transmission member 304 is connected between the rotating shaft 302 and the rotating rod 303. The missing gear 209 is coaxially fixed to the rotating shaft 302. The missing gear 209 can drive the rotating rod 303 to rotate through the rotating shaft 302 and the second belt transmission member 304. The diameter of the rotating shaft 302 is twice the diameter of the rotating rod 303. The L-shaped sliding rod 305 is connected to the rotating shaft 302 and the rotating rod 303. The movable rod 305 is slidably set in the workbench 1, and an arc-shaped sliding groove is opened on the rotating rod 303. One end of the L-shaped sliding rod 305 is slidably set in the arc-shaped sliding groove on the rotating rod 303. When the rotating rod 303 rotates, it can push the L-shaped sliding rod 305 to slide along the workbench 1. The connecting push rod 306 is slidably set on the workbench 1. The connecting push rod 306 is fixedly connected to the L-shaped sliding rod 305. The connecting push rod 306 passes through the L-shaped sliding rod 3 and is slidably connected thereto. The pushing spring 307 is set between the connecting push rod 306 and the L-shaped sliding rod 3, and the two ends of the pushing spring 307 are respectively fixed on the connecting push rod 306 and the L-shaped sliding rod 3.

[0042] When the missing gear 209 rotates, it can drive the rotating shaft 302 to rotate. When the rotating shaft 302 rotates, it can drive the rotating rod 303 to rotate through the second belt transmission member 304. The diameters of the pulleys in the second belt transmission member 304 correspond to the diameters of the rotating shaft 302 and the rotating rod 303 respectively, and because the diameter of the rotating shaft 302 is twice the diameter of the rotating rod 303, after the rotating shaft 302 rotates 90 degrees with the missing gear 209, the rotating rod 303 will rotate 180 degrees. During the rotation of the rotating rod 303, the L-shaped sliding rod 305 will slide along the workbench 1 under the action of the arc-shaped sliding groove outside the rotating rod 303, and the connecting push rod 306 will slide with the L-shaped sliding rod 305 and compress the pushing spring 307. When the connecting ring 206 drives the blocking assembly to release the restriction on the L-shaped sliding rod 3, the pushing spring 307 can push the L-shaped sliding rod 3 and the cutter 301 to move toward the workpiece and cut off the excess material outside the workpiece, thereby realizing the function of trimming the workpiece.

[0043] The blocking assembly can be directly realized by using a cylinder in the prior art to drive the blocking member to move, such as Fig.10 and Fig.11 As shown, the present invention also provides a mechanical blocking component. Compared with the electronic control method of the prior art, the mechanical structure has a low failure rate and can operate stably for a long time. The blocking component includes a transmission component, a wedge block 404 and a limit spring 405. The transmission component includes a friction wheel 4, a turntable 401, an arc-shaped sliding rod 4011, a connecting spring 4012, a rotating pull rod 402, a guide wheel 403 and a pull rope 406. The friction wheel 4 is rotatably arranged on the workbench 1, the turntable 401 is fixedly connected to the shaft of the friction wheel 4, and the friction wheel 4 is in contact with the connecting ring 206. When the connecting ring 206 rotates, the friction force The friction wheel 4 is driven to rotate, the arc-shaped sliding rod 4011 is slidably set in the turntable 401, the connecting spring 4012 is set between the arc-shaped sliding rod 4011 and the turntable 401, and the connecting spring 4012 can push the arc-shaped sliding rod 4011 to slide and reset along the turntable 401, the rotating pull rod 402 is rotatably set on the workbench 1, the wire wheel 403 is rotatably set on the workbench 1, the wedge block 404 is slidably set on the workbench 1, the limit spring 405 is set between the wedge block 404 and the workbench 1, and the pull rope 406 is passed around the wire wheel 403 and its two ends are respectively fixed on the rotating pull rod 402 and the wedge block 404.

[0044] When the missing gear 209 rotates 90 degrees, the rotating motor 102 has not started yet. At this time, the L-shaped sliding rod 3 is restricted by the wedge block 404 and cannot approach the workpiece. After the rotating motor 102 is started, it can drive the rotating cylinder 2 to rotate through the first pulley. The rotation speed of the rotating cylinder 2 gradually increases and finally remains stable. During the rotation of the rotating cylinder 2, the connecting ring 206 rotates accordingly. When the connecting ring 206 rotates, it drives the friction wheel 4 to rotate through the friction force. The friction wheel 4 drives the turntable 401 to rotate. When the turntable 401 rotates, the arc-shaped sliding rod 4011 is affected by the centrifugal force to slide along the turntable 401 and compress the connecting spring 4012. The sliding of the arc-shaped sliding rod 4011 will push the rotating pull rod 402 to rotate. The rotating pull rod 402 can pull the wedge block 404 along the workpiece through the pull rope 406 The working table 1 slides, and when the rotating cylinder 2 rotates at a sufficiently large speed, the arc-shaped sliding rod 4011 pushes the rotating pull rod 402 to rotate at a sufficiently large angle. At this time, the rotating pull rod 402 can pull the wedge block 404 to move a sufficient distance through the pull rope 406 to make the wedge block 404 disengage from the L-shaped sliding rod 3. At this time, under the action of the pushing spring 307, the L-shaped sliding rod 3 can drive the cutter 301 to move toward the workpiece. After the processing is completed, the rotating cylinder 2 stops rotating, and the limit spring 405 can push the wedge block 404 to slide and reset. When the L-shaped sliding rod 3 moves and resets, it will contact the inclined surface of the wedge block 404. Since the elastic force of the pushing spring 307 is greater than the elastic force of the limit spring 405, the L-shaped sliding rod 3 can automatically push the wedge block 404 away at this time, thereby realizing the function of blocking the L-shaped sliding rod 3.

[0045] like Figure 12-14As shown, the curling mechanism includes a reciprocating screw 5, a third belt transmission member 501, an L-shaped rack 502, a transmission gear 503, a worm 504, a fixed bracket 505, a rotating screw 506, a worm wheel 507, an L-shaped rod 508, an L-shaped rotating rod 509 and a pressure reel 510. The reciprocating screw 5 is rotatably arranged on the workbench 1. The third belt transmission member 501 is connected to the rotating motor 102 and the reciprocating screw 5. The rotating motor 102 can drive the reciprocating screw 5 to rotate through the third belt transmission member 501. The L-shaped rack 502 is slidably arranged on the workbench 1. The L-shaped rack 502 is threadedly connected to the reciprocating screw 5. The transmission gear 503 is rotatably arranged in the workbench 1. The L-shaped rack 502 is meshed with the transmission gear 503. The worm 504 is fixedly connected to the driven gear 503. The movable screw 506 is rotatably set on the workbench 1, the worm wheel 507 is fixedly connected to the rotating screw 506, the worm wheel 507 is meshed with the worm 504, the transmission gear 503 can drive the worm wheel 507 to rotate through the worm 504, the L-shaped rod 508 is slidably set on the workbench 1, the L-shaped rod 508 is threadedly connected with the rotating screw 506, the fixed bracket 505 is fixedly connected to the workbench 1, the L-shaped rotating rod 509 is rotatably set on the fixed bracket 505, and the pressure coil 510 is set on the fixed bracket 505; through the above improvements, after the workpiece is processed by the cutter 301, the L-shaped rack 502 can just drive the worm 504 to rotate through the transmission gear 503, so that the pressure coil 510 is close to the workpiece, so that the shearing and curling processes are connected, thereby improving the processing efficiency.

[0046] When the rotating motor 102 is started, the reciprocating screw rod 5 can be driven to rotate through the third belt transmission member 501. When the reciprocating screw rod 5 rotates, the L-shaped rack 502 can slide along the workbench 1. When the cutter 301 has sheared the workpiece, the L-shaped rack 502 can just mesh with the transmission gear 503 and drive it to rotate. When the transmission gear 503 rotates, the worm gear 507 and the rotating screw rod 506 can be driven to rotate through the worm 504. When the rotating screw rod 506 rotates, it will drive the L-shaped rod 508 to slide along the workbench 1. During the movement of the L-shaped rod 508, it will push the L-shaped When the rotating rod 509 rotates, the L-shaped rotating rod 509 can make the pressure coiling disk 510 swing downward and contact with the workpiece, and the rotating workpiece is curled. When the L-shaped rack 502 moves and resets along the reciprocating screw 5, the workpiece curling is completed, and the transmission gear 503 drives the worm wheel 507 and the rotating screw 506 to rotate in the opposite direction through the worm 504, and the L-shaped rod 508 slides and resets along the workbench 1. Since the end of the L-shaped rotating rod 509 away from the pressure coiling disk 510 is heavier, the L-shaped rotating rod 509 can automatically rotate and reset, thereby realizing the function of curling the workpiece.

[0047] like Fig.14As shown, the fixed bracket 505 includes a limit block 5051, which is fixedly installed in the fixed bracket 505. The limit block 5051 is used to limit the position of the L-shaped rotating rod 509. Through the above improvement, the L-shaped rotating rod 509 can quickly return to a stable state and proceed to the next processing.

[0048] When the L-shaped rotating rod 509 rotates to reset, the limit block 5051 will limit the L-shaped rotating rod 509, so that the L-shaped rotating rod 509 quickly stops for the next processing.

[0049] like Figure 15-17 As shown, the workbench 1 also includes a fixed frame 6, a sliding rack 601, a spur gear 602 and a push rack 603. The fixed frame 6 is fixedly connected to the workbench 1, and the sliding rack 601 is slidably set on the fixed frame 6. The connecting ring 206 is slidably engaged with the sliding rack 601. When the sliding block 203 slides and resets, it can drive the sliding rack 601 to slide along the fixed frame 6 through the connecting ring 206. The spur gear 602 is rotatably set on the fixed frame 6, the sliding rack 601 is meshed with the spur gear 602, and the push rack 603 is slidably set on the workbench 1. The push rack 603 is meshed with the spur gear 602. When the sliding rack 601 slides along the fixed frame 6, it can drive the push rack 603 to move through the spur gear 602; through the above improvements, after the workpiece is processed, the push rack 603 can automatically push the workpiece on the rotating cylinder 2 outward, thereby realizing the function of automatic discharging.

[0050] When the connecting rod 213 moves to reset, the movable frame 208 drives the connecting ring 206 to move and reset through the connecting block 207. At this time, the connecting ring 206 will drive the sliding rack 601 to slide along the fixed frame 6 and drive the spur gear 602 to rotate. When the spur gear 602 rotates, it can drive the pushing rack 603 to move toward the workpiece and push the workpiece out from the rotating cylinder 2. When the connecting rod 213 moves in the direction of the rotating cylinder 2, the sliding rack 601 will move and reset under the drive of the connecting ring 206, and the pushing rack 603 will reset accordingly, realizing the function of automatic pushing.

[0051] like Fig.17 As shown, the fixed frame 6 includes a positioning block 604 and a positioning spring 605. The positioning block 604 is slidably set on the fixed frame 6. The positioning block 604 can locate the position of the workpiece to prevent the workpiece from moving during rotation. The positioning spring 605 is set between the fixed frame 6 and the positioning block 604; through the above improvement, during the process of the workpiece rotating with the rotating cylinder 2, the workpiece will be restricted by the positioning block 604, which can prevent the workpiece from sliding back and forth on the rotating cylinder 2.

[0052] When the workpiece is sleeved on the rotating cylinder 2, it will contact the positioning block 604, and then the rotating disk 212 will press the workpiece against the positioning block 604 and compress the positioning spring 605. When the workpiece rotates, the positioning block 604 and the rotating disk 212 will clamp the workpiece together to prevent the workpiece from moving back and forth on the rotating cylinder 2, thereby ensuring the processing effect.
