[0014] The operation method of the cutting machine for bolt sleeve blank comprises the following steps: Step one, the worker needs to adjust the length limiting module to a suitable position according to the actual cutting demand, then the worker puts the sleeve blank into the sleeve conveying module by hand, the sleeve blank entering the sleeve conveying module will be straightly conveyed until one end of the sleeve blank abuts against the length limiting module, when the sleeve blank abuts against the length limiting module, the length limiting module will be triggered to start by the sleeve blank, so that the length limiting module transmits a starting signal to the cutting module, after receiving the starting signal, the cutting module will cut the sleeve blank directly, the cut sleeve blank directly falls onto the cutting module and finally falls into the second base, and then falls along the second base into the collecting vehicle placed in advance; Step two, when the worker holds the sleeve blank, the position should be at the end of the sleeve blank, so as to prevent the hand from being squeezed. After the end of the sleeve blank is inserted into the sleeve conveying module, the sleeve blank will be squeezed between the top disc and the bottom disc. When the diameter of the sleeve blank is large, the sleeve blank will be squeezed upward and left and right, so that the top disc and the bottom disc move upward and downward respectively, and then the third spring between them is stretched, and the second spring and the fourth spring are squeezed, so that the top disc and the bottom disc adapt to the size of the sleeve blank. At the same time, the horizontal squeezing force of the sleeve blank squeezes the C-shaped plate to the lateral vertical plate direction. When the C-shaped plate is squeezed to the lateral vertical plate direction, the first spring of the C-shaped plate is also compressed and deformed, and then the C-shaped plate actively adapts to the horizontal squeezing of the sleeve blank, so that the C-shaped plate adapts to the size of the sleeve blank in the horizontal direction. The two actively adapt to the size of the sleeve blank in the vertical and horizontal directions, so that the device can help the factory reduce the procurement cost to a certain extent. When the size of the sleeve blank is small, the top disc, the bottom disc and the C-shaped plate do not need to change their existing state; Step three, when the end of the sleeve blank is conveyed to the start button on the signal release device of the length limiting module by the sleeve conveying module, the start button is squeezed, and the signal release device releases the start signal to the cutting module. After the signal receiver of the cutting module receives the signal start signal, the cylinder starts to work. When the cylinder works, the cylinder rod moves downward, and the first square block, the screw base, the second square block and the cutting knife move downward together. The cutting knife can cut the sleeve blank instantly. Before the cutting knife falls, the worker needs to start the screw servo motor through the controller in advance, so that the screw starts to rotate, and then the screw thread mover moves horizontally on the screw with the polishing sandpaper. The polishing sandpaper is used to polish the burrs on the end face of the sleeve blank. When the cutting knife falls, the polishing sandpaper also polishes the end face part of the sleeve blank that has been cut, so as to reduce the possibility of affecting the appearance and quality of the product due to the burrs on the end face of the sleeve blank to a certain extent; Step four, when the sleeve blank is conveyed to the front of the length limiting module by the sleeve conveying module, because the worker will move the front plate, the fifth spring connected thereto, the back plate and the signal release device to the appropriate position in the long chute plate through the chute block in advance before starting work according to the actual cutting length, and then fix the chute block on the long chute plate by using the connecting bolt, at this time, the worker will first open the signal release device, when the end of the sleeve blank is conveyed to the starting button on the signal release device, the signal release device will release the cylinder starting signal to the cutting module, so that the cutting module completes the cutting action, when the cutting module cuts, the extrusion force generated during cutting will extrude the cut sleeve blank towards the front plate, the front plate is extruded, the fifth spring is compressed and deformed, and then the front plate moves towards the back plate, because the front plate shrinks after cutting, the cut sleeve blank lacks a force to resist, so the sleeve blank directly falls onto the second base, and the middle part of the second base is provided in the form of a slide, and the falling sleeve blank slides into the collection vehicle prepared in advance.

[0015] Compared with the prior art, the present application has at least the following beneficial effects: In the above scheme, the sleeve conveying module is provided, so that the device can adapt to various models and various diameters of sleeve channels, which makes it unnecessary for the factory to purchase conveying devices suitable for different models of sleeves, thereby reducing the procurement cost of the factory to a certain extent.

[0016] The cutting module is provided, so that the device can perform deburring on the end face of the sleeve while cutting the sleeve, which can reduce the possibility of affecting the appearance and quality of the product due to burrs on the end face of the sleeve to a certain extent.

[0017] The length limiting module is provided, so that the device can limit the cutting length of the pipe and automatically drop the cut sleeve through mechanical linkage, which can reduce the probability of device failure after long-term use, thereby reducing the possibility of normal work suspension of the factory due to mechanical equipment failure.

[0018] In summary, the present application has the advantages that the device can adapt to various models and sizes of sleeves, reduces the procurement cost of the factory, can perform deburring on the end face of the sleeve, reduces the possibility of affecting the appearance and quality of the product, and the device automatically drops the sleeve through a pure mechanical way, thereby reducing the probability of device failure.

[0043] By setting the length limiting module 5, the device can not only limit the cutting length of the pipe, but also automatically drop the cut sleeve through mechanical linkage, which may reduce the probability of device failure after long-term use, thereby reducing the possibility of normal work suspension of the factory caused by mechanical equipment failure.

[0044] The electrical components appearing in this article are all connected with the main controller and 220V mains electricity, and the main controller can be a computer or other commonly known devices that can be controlled.

[0045] The operation method of the cutting machine for bolt sleeve blanks comprises the following steps when in use: Step one, the worker needs to adjust the length limiting module 5 to a suitable position according to the actual cutting demand, then the worker puts the sleeve blank into the sleeve conveying module 2 with his hand, the sleeve blank entering the sleeve conveying module 2 will be straightly conveyed until the end of the sleeve blank hits the length limiting module 5, when the sleeve blank hits the length limiting module 5, the length limiting module 5 will be triggered to start by the sleeve blank, so that the length limiting module 5 transmits the start signal to the cutting module 3, after receiving the start signal, the cutting module 3 will cut off the sleeve blank directly, the cut sleeve blank will directly fall onto the cutting module 3 and finally fall into the second base 4, and then roll along the second base 4 and fall into the collecting vehicle placed in advance; Step two, when the worker holds the sleeve blank, the worker should hold the sleeve blank at the rear end position to prevent hand injury. After the sleeve blank end is inserted into the sleeve conveying module 2, the sleeve blank will be squeezed between the top disc 218 and the bottom disc 222. When the diameter of the sleeve blank is large, the sleeve blank will be squeezed upward and left and right, so that the top disc 218 and the bottom disc 222 move upward and downward respectively, and then the third spring 220 between them is stretched, and the second spring 217 and the fourth spring 223 are squeezed, so that the top disc 218 and the bottom disc 222 adapt to the size of the sleeve blank. At the same time, the horizontal squeezing force of the sleeve blank will squeeze the C-shaped plate 203 towards the lateral vertical plate 201. When the C-shaped plate 203 is squeezed towards the lateral vertical plate 201, the first spring 202 will also be compressed and deformed, and then the C-shaped plate 203 will actively adapt to the horizontal squeezing of the sleeve blank, so that the C-shaped plate 203 adapts to the size of the sleeve blank in the horizontal direction, and the two actively adapt to the size of the sleeve blank in the vertical and horizontal directions, so that the device can help the factory reduce the procurement cost to a certain extent. When the size of the sleeve blank is small, the top disc 218, the bottom disc 222 and the C-shaped plate 203 do not need to change their existing state; Step three, when the end of the sleeve blank is conveyed to the start button 509 on the signal release device 507 of the length limiting module 5 by the sleeve conveying module 2, the start button 509 is squeezed, and the signal release device 507 releases the start signal to the cutting module 3. After the signal receiver 303 of the cutting module 3 receives the signal start signal, the cylinder 302 starts to work. When the cylinder 302 works, the cylinder rod 305 moves downward, and the first square block 306, the screw base 307, the second square block 314 and the cutting knife 315 move downward together. The cutting knife 315 can cut the sleeve blank instantly. Before the cutting knife 315 falls, the worker needs to start the screw servo motor 308 through the controller 309 in advance, so that the screw rod 310 starts to rotate, and then the screw thread mover 311 moves horizontally on the screw rod 310 with the polishing sandpaper 313. The polishing sandpaper 313 is used to polish the burrs on the end face of the sleeve blank. When the cutting knife 315 falls, the polishing sandpaper 313 also polishes the end face part of the sleeve blank that has been cut, so as to reduce the possibility of affecting the appearance and quality of the product due to the burrs on the end face of the sleeve blank to a certain extent; Step four, when the sleeve blank is delivered in front of the length limiting module 5 by the sleeve conveying module 2, because the worker will move the front plate 504, the fifth spring 505 connected with the front plate 504, the back plate 506 and the signal releaser 507 to the appropriate position in the long chute plate 501 through the chute block 503 in advance according to the actual cutting length before starting work, and then fix the chute block 503 on the long chute plate 501 by using the connecting bolt 502, at this time the worker will open the signal releaser 507, when the end of the sleeve blank is delivered and reaches the start button 509 on the signal releaser 507, the signal releaser 507 will release the cylinder start signal to the cutting module 3 at this time, so that the cutting module 3 completes the cutting action, when the cutting module 3 cuts, the extrusion force generated during cutting will extrude the cut sleeve blank to the front plate 504 direction, the front plate 504 is extruded, the fifth spring 505 will be compressed and deformed, and then the front plate 504 will move to the back plate 506 direction, because the front plate 504 shrinks after cutting, the cut sleeve blank lacks a force to resist, so the sleeve blank directly falls onto the second base 4, and the middle part of the second base 4 is set in the form of a slide, the falling sleeve blank slides along the slide to the collection car prepared in advance.

[0046] The technical scheme provided by the present application is: workers need to adjust the length limiting module 5 to a suitable position according to the actual cutting demand, and then workers put the sleeve blank into the sleeve conveying module 2 by hand, the sleeve blank entering the sleeve conveying module 2 will be straightly conveyed until the end of the sleeve blank abuts against the length limiting module 5, when the sleeve blank abuts against the length limiting module 5, the length limiting module 5 will be triggered and started by the sleeve blank, so that the length limiting module 5 transmits a starting signal to the cutting module 3, after receiving the starting signal, the cutting module 3 will cut the sleeve blank directly, the cut sleeve blank directly falls on the cutting module 3 and finally falls into the second base 4, and then falls into the collecting vehicle placed in advance along the second base 4, when workers hold the sleeve blank, the holding position should be at the rear position of the end of the sleeve blank to prevent the hand from being squeezed, after the end of the sleeve blank is put into the sleeve conveying module 2, the sleeve blank will be squeezed between the top disc 218 and the bottom disc 222, when the diameter of the sleeve blank is large, the sleeve blank will be squeezed upward and left and right, so that the top disc 218 and the bottom disc 222 move upward and downward respectively, thereby stretching the third spring 220 between them, and the second spring 217 and the fourth spring 223 are squeezed, so that the top disc 218 and the bottom disc 222 adapt to the size of the sleeve blank, while the top disc 218 and the bottom disc 222 adapt to the size of the sleeve blank by moving up and down, the horizontal squeezing force of the sleeve blank will squeeze the C-shaped plate 203 to the lateral vertical plate 201, when the C-shaped plate 203 is squeezed to the lateral vertical plate 201, the first spring 202 will also be compressed and deformed, thereby the C-shaped plate 203 actively adapts to the horizontal squeezing of the sleeve blank, so that the C-shaped plate 203 adapts to the size of the sleeve blank in the horizontal direction, and the two actively adapt to the size of the sleeve blank in the vertical direction and the horizontal direction, so that the device can help the factory to reduce the procurement cost to a certain extent, when the size of the sleeve blank is small, the top disc 218, the bottom disc 222 and the C-shaped plate 203 do not need to change their existing states, when the end of the sleeve blank is conveyed to the starting button 509 on the signal release device 507 of the length limiting module 5 by the sleeve conveying module 2, after the starting button 509 is squeezed, the signal release device 507 releases a starting signal to the cutting module 3, and after the signal receiver 303 of the cutting module 3 receives the signal starting signal, the cylinder 302 starts to work, when the cylinder 302 works, the cylinder rod 305 moves downward, and when the cylinder rod 305 moves downward, the first square block 306, the screw base 307, the second square block 314 and the cutting knife 315 move downward together, the cutting knife 315 can cut the sleeve blank instantly, before the cutting knife 315 falls, the worker needs to start the screw servo motor 308 through the controller 309 in advance,The screw rod 310 starts to rotate, and then the screw rod 310 moves horizontally with the abrasive paper 313, so as to polish the burrs on the end face of the sleeve blank, and the abrasive paper 313 also polishes the end face of the sleeve blank when the cutting knife 315 falls, so that the burrs on the end face of the sleeve blank can be polished, and the possibility of affecting the appearance and quality of the product can be reduced, when the sleeve blank is conveyed to the front of the length limiting module 5, the worker will move the front plate 504, the fifth spring 505 connected with the front plate 504, the back plate 506 and the signal release device 507 to the appropriate position in the long groove plate 501 through the sliding groove block 503 in advance before starting work according to the actual cutting length, and then the sliding groove block 503 is fixed on the long groove plate 501 by using the connecting bolt 502, at this time, the worker will open the signal release device 507, when the end of the sleeve blank is conveyed to the start button 509 on the signal release device 507, the signal release device 507 releases the cylinder starting signal to the cutting-off module 3, so that the cutting-off module 3 completes the cutting action, when the cutting-off module 3 cuts, the extrusion force generated during cutting extrudes the cut sleeve blank to the front plate 504, the front plate 504 is extruded, and the fifth spring 505 is compressed and deformed, so that the front plate 504 moves to the back plate 506, because the front plate 504 is contracted, the cut sleeve blank lacks a force to resist, so the sleeve blank directly falls on the second base 4, and the middle part of the second base 4 is provided with a slide, and the falling sleeve blank slides to the collecting vehicle prepared in advance.

10. The method of operating the cutting machine for bolt sleeve blanks according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: The worker needs to adjust the length limiting module (5) to a suitable position according to the actual cutting requirements. Then, the worker inserts the sleeve blank into the sleeve conveying module (2) by hand. The sleeve blank entering the sleeve conveying module (2) will be conveyed straight until one end of the sleeve blank hits the length limiting module (5). When the sleeve blank hits the length limiting module (5), the length limiting module (5) will be triggered by the sleeve blank, so that the length limiting module (5) transmits the start signal to the cutting module (3). After receiving the start signal, the cutting module (3) will cut the sleeve blank directly. The cut sleeve blank will fall directly onto the cutting module (3) and finally into the second base (4). Then, it will roll down along the second base (4) into the collection car that has been placed in advance. Step 2: After the worker picks up the sleeve blank (the worker should pick it up from the rear of the end of the sleeve blank to prevent hand injury), the sleeve blank is inserted into the sleeve conveying module (2) at the end. The sleeve blank will first be squeezed between the top disc (218) and the bottom disc (222). When the diameter of the sleeve blank is large, the sleeve blank will be squeezed upward and to the left and right, so that the top disc (218) and the bottom disc (222) move upward and downward respectively, which will stretch the third spring (220) between them, while the second spring (217) and the fourth spring (223) will be squeezed, so that the top disc (218) and the bottom disc (222) adapt to the size of the sleeve blank. While adapting to the size of the cylindrical blank through up-and-down movement, the horizontal extrusion force of the cylindrical blank will cause the C-shaped plate (203) to be extruded towards the lateral vertical plate (201). When the C-shaped plate (203) is extruded towards the lateral vertical plate (201), its first spring (202) will also be compressed and deformed, thereby causing the C-shaped plate (203) to actively adapt to the horizontal extrusion of the cylindrical blank, so that the C-shaped plate (203) adapts to the size of the cylindrical blank in the horizontal direction. Both adapt to the size of the cylindrical blank in the vertical and horizontal directions, so that the device can help the factory reduce procurement costs to a certain extent. When the size of the cylindrical blank is small, the top disc (218), bottom disc (222), and C-shaped plate (203) do not need to change their existing state. Step 3: When the end of the sleeve blank is conveyed by the sleeve conveying module (2) to the start button (509) on the signal release device (507) of the length limiting module (5), after the start button (509) is squeezed, the signal release device (507) will release a start signal to the cutting module (3). After the signal receiver (303) of the cutting module (3) receives the start signal, the cylinder (302) starts to work. When the cylinder (302) works, the cylinder rod (305) will move downward. When the cylinder rod (305) moves downward, it will drive the first square block (306), the lead screw base (307), the second square block (314) and the cutting blade (315) to move together. During the downward movement, the cutting blade (315) can instantly cut the sleeve blank. Before the cutting blade (315) falls, the worker needs to start the lead screw servo motor (308) in advance through the controller (309) so that the lead screw (310) starts to rotate. Then, the thread actuator (311) carries the sandpaper (313) to make horizontal movement on the lead screw (310). The sandpaper (313) is used to smooth the burrs on the end face of the sleeve blank. When the cutting blade (315) falls, the sandpaper (313) will also grind the end face of the sleeve blank that has been cut, thereby reducing the possibility of affecting the aesthetics and quality of the product due to the presence of burrs on the end face of the sleeve to a certain extent. Step 4: When the sleeve blank is conveyed to the length limiting module (5) by the sleeve conveying module (2), the worker will move the front plate (504) and the connected fifth spring (505), back plate (506) and signal release device (507) to the appropriate position in the long slide plate (501) in advance through the slide block (503) according to the actual cutting length requirements before starting work. Then, the slide block (503) is fixed to the long slide plate (501) using the connecting bolt (502). At this time, the worker will first open the signal release device (507). When the end of the sleeve blank touches the start button (509) on the signal release device (507) during conveying, the signal release device (507) will then open. 7) The cylinder start signal will be released to the cutting module (3), so that the cutting module (3) completes the cutting action. When the cutting module (3) cuts, the extrusion force generated during the cutting will press the cut sleeve blank towards the front plate (504). When the front plate (504) is compressed, the fifth spring (505) will be compressed and deformed, and then the front plate (504) will move towards the back plate (506). Because the front plate (504) is contracted, the cut sleeve blank lacks a force to resist it, so the sleeve blank falls directly onto the second base (4). The middle part of the second base (4) is set with a slope. The fallen sleeve blank slides along the slope into the pre-prepared collection vehicle.
