Description

Technical Field

[0001] The present invention relates to the technical field of cable cutting, in particular to a cable cutting device and a cutting method. Background Art

[0002] In the production process of cables, the cutting of cables is indispensable. The traditional cutting method is to hold the cables by hand and then cut them with a switch. This cutting method is not only unsafe, but also has large cutting errors. In addition, there is another method that presses one end of the cable with a pressure block and then cuts it with a switch. Although the safety of cutting is improved, the cutting efficiency and cutting quality are still not up to par.

[0003] Therefore, automated cutting equipment is particularly important. Currently, commonly used automated cutting equipment usually uses front and rear dual conveying parts, and the middle position is set to cut parts. There are still the following problems in its use:

[0004] Since the cut cable will be flattened and deformed at the cut position, the deformed end is not easy to reinsert into the shear tool, and is also not easy to re-transport to the conveying parts located at the rear station.

[0005] When processing the cut end of the cable, since the cut end of the cable is close to the cutting edge, how to solve the obstruction formed by the cutting edge when processing the cable end is also an urgent problem to be solved.

[0006] Since there is a certain gap between the shearing tool and the conveying parts of the subsequent workstation, the processed cable end is prone to deflection when it re-passes through the cutting edge and connects with the conveying parts of the subsequent workstation, which has a certain impact on the cutting angle accuracy of the subsequent cable. Summary of the invention

[0007] 1. Technical issues to be resolved

When processing the cut end position of the cable, since the cut end position of the cable is close to the cutting edge position, how to solve the obstruction formed by the cutting edge when processing the cable end is also an urgent problem to be solved. In addition, since there is a certain gap space between the shear tool and the conveying parts of the rear section station, the processed cable end is prone to deflection when it passes through the cutting edge again and connects with the conveying parts of the rear section station, thereby affecting the cutting angle accuracy of the subsequent cable.

[0020] A cable cutting method comprises the following steps:

[0021] S1: First, one end of the cable to be cut passes through the middle of a plurality of relatively staggered compression sleeves, and then a pair of sliders are tightened to apply tension, so that the slider drives the compression sleeve on the mounting frame to apply pressure to the cable, and because the plurality of compression sleeves are relatively staggered, the cable passing through them is straightened;

[0022] S2: The pre-straightened cable then passes through the straightening hole opened in the straightening block, and since the inner diameter of the straightening hole is equal to the outer diameter of the cable and the straightening hole has a certain length, the cable passing through the straightening hole is further straightened and flattened;

[0023] S3: The cable straightened by the double leveling process then passes through the front driving assembly, the adjusting assembly and the cutting assembly and passes out of the rear driving assembly, and the initial position of the rotating frame is horizontal due to the tension applied by the tension spring 2 provided in the adjusting assembly, thereby adaptively adjusting the conveying position of the cable;

[0024] S4: During transportation, the servo motor 1 of the front drive assembly and the rear drive assembly is started, the servo motor 1 rotates to make the rotating shaft 2 drive the supporting wheel to rotate, and the pressing wheel is pressed against the cable passing through the annular groove provided on the supporting wheel by the pressing spring, so that the cable is driven to be transported by the friction between the supporting wheel and the cable;

[0025] S5: When cutting, by starting the shear cylinder, one end of the shear cylinder piston rod extends and drives the upper shear frame and the upper shear knife to move downward. At the same time, through the gear, the upper rack moves downward while the lower rack drives the lower shear frame to move upward synchronously, so that the lower shear knife set on the lower shear frame moves towards the upper shear knife and cuts the cable located therein through the V-shaped blade.

[0026] S6: The cut cables in the rear process are transported through the rear drive assembly, while the cables in the front process need to be reinserted into the shearing tool and the rear drive assembly through the front drive assembly. Therefore, the finger cylinder set by the clamping mechanism moves the clamping arm to clamp the cable. Since the inner diameter of the jacket set by the smoothing mechanism is equal to the cable diameter, the jacket set by the smoothing mechanism wraps the cable. Then, by starting the servo motor 2, the servo motor 2 drives the synchronous pulley to rotate through the synchronous belt. At this time, the synchronous belt drives the smoothing mechanism to move along the guide rail 1 to the position state 2, so that the jacket set by the smoothing mechanism moves along the cable to the cut end and rounds it.

[0027] S7: At the same time, when the smoothing mechanism moves and disengages from the photoelectric switch 1 in position state 1, the photoelectric switch 1 senses and cuts off the power supply of the electromagnetic lock, and the electromagnetic lock tongue retracts and disengages from the lock sleeve. At the same time, the smoothing mechanism moves through the extrusion plate to contact and squeeze the force plate provided in the cutting component, so that the mounting seat moves along the guide rail 3 through the slide table, and avoids the position of the cable end after cutting;

[0028] S8: After the cable end is flattened, the flattening mechanism is reset to position state 1. At this time, the cutting assembly is reset by the reset spring, and the photoelectric switch 1 senses the reset of the flattening mechanism and connects the power supply of the electromagnetic lock, so that the electromagnetic lock tongue is extended and re-engaged with the lock sleeve, thereby fixing the cutting assembly;

[0029] S9: The clamping mechanism then releases the clamping state of the cable, and conveys the cable by starting the front drive assembly, so that the straightened cable passes through the blade of the cutting assembly, and the cable end conveyed from the blade is guided and positioned by the guide cone tube, so that the cable is conveyed along a preset trajectory, and the gap with the rear drive assembly is reduced by the extension tube, so that the cable enters the rear drive assembly. At this time, the rear drive assembly rotates and re-compresses the cable to form a compressed conveying state, thereby completing the high-precision cutting operation of the cable.

[0030] (III) Beneficial effects

[0031] Compared with the prior art, the present invention provides a cable cutting device and a cutting method, which have the following beneficial effects:

[0032] 1. The cable cutting equipment in the present invention integrates the processing steps of conveying, straightening, cutting and post-processing of cutting, and each processing step is closely coordinated. The equipment is highly integrated and automated, and the cable cutting process is not only highly accurate, but also significantly efficient.

[0033] 2. The finger cylinder of the clamping mechanism of the present invention moves the clamping arm to clamp the cable, and then the clamping sleeve of the smoothing mechanism moves along the cable to the cut end, and rounds the cut cable end, so as to facilitate the reinsertion of the cable into the shearing tool.

[0034] 3. The present invention cooperates with an electromagnetic lock and a photoelectric switch, and the smoothing mechanism moves through the extrusion plate to contact and squeeze the force plate set in the cutting component, so that the cutting component moves and the position of the cable end after cutting is avoided, effectively avoiding the situation where it hinders the cable end from being rounded by the smoothing mechanism.

[0035] 4. The present invention guides and positions the end of the cable conveyed from the knife edge through a guiding cone tube, so that the cable is conveyed along a preset trajectory, and reduces the gap with the rear drive assembly through an extension tube, thereby effectively improving the cable conveying accuracy.

[0036] 5. The present invention pre-straightens the cable by using multiple sets of compression sleeves provided by the pre-straightening component, and then the pre-straightened cable is secondarily flattened through the straightening holes provided by the secondary straightening component, thereby effectively improving the straightening and flattening effect of the cable.

[0037] 6. The present invention applies tension to the rotating shaft 3 through the force arm by means of two tension springs 2 provided in the adjustment component, so that the rotating frame can not only rotate at an adaptive angle, but also the tension applied by the tension spring 2 makes the initial position of the rotating frame horizontal, thus enabling the rotating frame to adaptively adjust the conveying position of the cable.

DETAILED DESCRIPTION

[0056] 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.

[0057] Reference Figure 1-Figure 17A cable cutting method includes a machine body, a stand 3 is provided on the top of the machine body, a cutting assembly 4 is provided on one side of the stand 3, a front driving assembly 5 and a rear driving assembly 1 for conveying the cable are provided at the front and rear stages of the cutting assembly 4, a smoothing assembly 2 for smoothing the end surface of the cut cable is provided at one side of the stand 3 and between the front driving assembly 5 and the cutting assembly 4, a pre-straightening assembly 6 and a secondary straightening assembly 9 for flattening the cable are provided at one side of the stand 3 and at the front station of the front driving assembly 5, and a The cable is cut before guiding the adjustment component 8, and one side of the cutting component 4 is provided with a guide component 10 for positioning the cable delivered to the rear drive component 1. One end of the reeled cable passes through the pre-straightening component 6, so that the cable passing therethrough is pre-straightened. The pre-straightened cable passes through the secondary straightening component 9 for further straightening. Then, the straightened cable after the double flattening process passes through the front drive component 5 and the cutting component 4 and passes out from the rear drive component 1. Since there is a certain gap between the front drive component 5 and the cutting component 4, it is necessary to ensure that the cable is in the front drive component 5 and the cutting component 4. The guiding positioning of the cutting component 4 during transportation, and the cable will be pulled tightly when it is cut by the cutting component 4, further affecting the guiding accuracy, so the adjusting component 8 is set to adaptively adjust the transportation position angle of the cable, and because the blade of the cutting component 4 is at a certain distance from the rear drive component 1, the cable in transportation is prone to deviation, resulting in problems in the connection between the cable end and the rear drive component 1 after cutting, so the guiding component 10 is set here to position the cable and transport it according to the preset trajectory, so as to improve the cable transportation accuracy, and after the cable is cut by the cutting component 4, the cut position of the cut cable will be flattened and deformed. If it is not rounded, the deformed end is not easy to reinsert into the shear tool, and it is not easy to re-insert into the rear drive component 1, so the deformed end is straightened by the smoothing component 2, which effectively improves the accuracy and efficiency of the cut cable automatically inserted into the subsequent processing station, this cable cutting equipment integrates the processing procedures of transportation, straightening, cutting and post-processing of cutting, and the various processing procedures are closely coordinated, the equipment is integrated and the degree of automation is high, the cable cutting process is not only high in accuracy, but also significantly improved in efficiency.

[0058] In order to realize the cutting operation with avoidance function, the cutting assembly 4 in the present invention includes two guide rails 3 61, and the two guide rails 3 61 are fixed to one side of the stand 3 by bolts. A mounting seat 55 is slidably connected between the two guide rails 3 61 through a slide, and a lower shearing frame 65 and an upper shearing frame 68 are slidably connected in the mounting seat 55 through a slide rail. The lower ends of the lower shearing frame 65 and the upper shearing frame 68 are respectively fixed with two lower shearing knives 66 and an upper shearing knife 69 that fit each other through bolts, and the lower shearing knife 66 and the upper shearing knife 69 are both provided with a V-shaped blade 70, and the upper ends of the lower shearing frame 65 and the upper shearing frame 68 are respectively fixed with a lower rack 64 and an upper rack 67 through bolts, and a gear rotatably connected to the lower rack 64 and the upper rack in the mounting seat 55 through an embedded bearing. A gear 63 meshed with 67, a shear cylinder 56 is fixed to one side of the mounting seat 55 by bolts, and one end of the piston rod of the shear cylinder 56 is fixed to the upper shear frame 68, a positioning frame 62 for blocking the position of the mounting seat 55 is fixed to one side of the vertical frame 3 by bolts, both ends of the positioning frame 62 are fixed with a reset spring 60 by bolts, and one end of the reset spring 60 is fixed to the mounting seat 55, a locking assembly 7 for fixing the position of the mounting seat 55 is provided on one side of the vertical frame 3, a force plate 57 is fixed to one side of the mounting seat 55 by bolts, by starting the shear cylinder 56, one end of the piston rod of the shear cylinder 56 is extended and drives the upper shear frame 68 and the upper shear knife 69 to move downward, and at the same time, the upper rack 67 is moved downward through the gear 63. At the same time, the lower rack 64 drives the lower shear frame 65 to move upward synchronously, so that the lower shear knife 66 and the upper shear knife 69 arranged on the lower shear frame 65 move toward each other and cut the cable located therein through the V-shaped blade 70. The locking assembly 7 includes an electromagnetic lock 58, which is fixed to one side of the stand 3 by bolts. The top of the mounting seat 55 is fixed with a lock sleeve 59 that is engaged with the lock tongue of the electromagnetic lock 58 by bolts. By starting the electromagnetic lock 58, the lock tongue is extended and inserted into the lock sleeve 59, so that the position of the cutting assembly 4 is fixed. The guide assembly 10 includes a mounting frame 71, which is fixed to one side of the mounting seat 55 by bolts. The bottom end of the mounting frame 71 is fixed with two fixing positions for the cable delivery position by bolts. There are two guide conical tubes 73 at the positions, and one end of each of the two guide conical tubes 73 is welded with an extension tube 72. After the cutting is completed, the cut cable at the subsequent station is transported through the rear drive component 1, and the cable at the preceding station is rounded by the smoothing component 2, and then continues to be transported through the front drive component 5 and passes through the blade of the cutting component 4. At this time, since the blade is at a certain distance from the rear drive component 1, the cable being transported is prone to deviation, resulting in problems in the connection between the cable end and the rear drive component 1. Therefore, by arranging the guide conical tube 73 here, the cable end transported from the blade can be guided and positioned, so that the cable is transported according to the preset trajectory, and the gap with the rear drive component 1 is reduced through the extension tube 72, thereby effectively improving the cable transportation accuracy.

[0059] In order to solve the problem of deformation of the cable end after being cut, the smoothing component 2 in the present invention includes a mounting frame 3 42, which is fixed to one side of the stand 3 by bolts, and the top of the mounting frame 3 42 is provided with a clamping mechanism 38 for clamping and fixing the cable and a smoothing mechanism 39 for smoothing the end surface of the cut cable, the clamping mechanism 38 is fixed to the top of the mounting frame 3 42 through a connecting frame 1 44, the smoothing mechanism 39 is slidably connected to two guide rails 1 43 fixed on the top of the mounting frame 3 42 through a slide, and the top of the mounting frame 3 42 is rotatably connected to two synchronous pulleys 41 through bearings. , two synchronous pulleys 41 are connected by synchronous belt transmission, and the synchronous belt is connected and fixed to the smoothing mechanism 39, the bottom of the mounting frame 3 42 is fixed with a servo motor 2 45 by bolts, one end of the output shaft of the servo motor 2 45 is fixed to one of the synchronous pulleys 41, and the top of the mounting frame 3 42 is fixed with a photoelectric switch 1 46 and a photoelectric switch 2 47 for positioning the position of the smoothing mechanism 39 by bolts, the model of the photoelectric switch is E3F-DS30C4, and the smoothing mechanism 39 has two position states: position state 1, which corresponds to the position of the photoelectric switch 1 46, that is, the initial state;Position state two, at this time corresponding to the position of the photoelectric switch two 47, the clamping mechanism 38 and the smoothing mechanism 39 both include a connecting plate 53, the top of the connecting plate 53 is fixed with a guide rail two 54 by bolts, the top of the guide rail two 54 is slidably connected with a connecting frame two 51 through a slide, one side of the connecting frame two 51 is fixed with a finger cylinder 50 by bolts, the model of the finger cylinder 50 is MHZ2-40D, the two driving arms of the finger cylinder 50 are fixed with clamping arms 49 by bolts, the two clamping arms 49 are respectively fixed with two clamping sleeves 48 distributed in an opposite manner by bolts, the top of the connecting plate 53 is fixed with an adjusting cylinder 52 by bolts, and the adjusting cylinder 52 One end of the piston rod is fixed to the second connecting frame 51, so that the horizontal position of the jacket 48 is finely adjusted by adjusting the cylinder 52, so that the cable is located in the middle of the two jackets 48. The inner diameter of the jacket 48 set on the clamping mechanism 38 is smaller than the cable diameter, and the inner diameter of the jacket 48 set on the smoothing mechanism 39 is equal to the cable diameter. One side of the connecting frame 51 provided with the smoothing mechanism 39 is fixed with an extrusion plate 40 for pushing the force plate 57 by bolts. Since the cut position of the cut cable will be flattened and deformed, if it is not rounded, the deformed end is not easy to reinsert into the shearing tool, and is also not easy to re-insert into the rear drive assembly 1, so The finger cylinder 50 provided by the clamping mechanism 38 needs to move the clamping arm 49 to make the jacket 48 clamp and fix the cable, and because the inner diameter of the jacket 48 provided by the smoothing mechanism 39 is equal to the diameter of the cable, the jacket 48 provided by the smoothing mechanism 39 forms a package around the cable, and then the servo motor 2 45 is started to drive the synchronous pulley 41 to rotate through the synchronous belt, and at this time the synchronous belt drives the smoothing mechanism 39 to move to the second position along the guide rail 1 43, so that the jacket 48 provided by the smoothing mechanism 39 moves along the cable to the cut end and rounds it. However, due to the difference between the cable cutting position and the cutting group The blade position of the component 4 is close, which hinders the smoothing mechanism 39. Therefore, when the smoothing mechanism 39 moves and disengages from the photoelectric switch 1 46 in position state 1, the photoelectric switch 1 46 senses and cuts off the power supply of the electromagnetic lock 58. At this time, the lock tongue of the electromagnetic lock 58 retracts and disengages from the locking sleeve 59. At the same time, the smoothing mechanism 39 moves through the extrusion plate 40 to contact and squeeze the force plate 57 set in the cutting component 4, so that the mounting seat 55 moves along the guide rail 3 61 through the slide table, and avoids the position of the cut cable end, effectively avoiding the situation that it hinders the cable end when it is rounded through the smoothing mechanism 39. ;

[0060] In order to realize the zoning transmission of cables, the front drive assembly 5 and the rear drive assembly 1 in the present invention both include a support wheel 25 and a pressure wheel 23. The support wheel 25 is rotatably connected to the inside of the stand 3 through a rotating shaft 24. Two annular grooves 26 equal to the diameter of the cable are provided on the outer circumference of the support wheel 25. A mounting frame 29 is fixed to the other side of the stand 3 by bolts. A servo motor 1 30 is fixed to one side of the mounting frame 29 by bolts, and one end of the output shaft of the servo motor 1 30 is fixed to the rotating shaft 24 by a coupling.

A rotating shaft 21 is rotatably connected in the moving block 28, and the rotating shaft 21 is rotatably connected in the moving block 28. The shaft 21 is connected and fixed with the pressure wheel 23 by a key, and a rubber sleeve 22 is bonded to the outer circumference of the pressure wheel 23. A clamping spring 27 is provided between the moving block 28 and the top inner wall of the slide groove 19. The moving block 28 can move freely up and down in the slide groove 19, and the clamping spring 27 can exert a downward force on the moving block 28 through elastic force, and make the pressure wheel 23 arranged on the moving block 28 clamp the cable passing through the annular groove 26 opened on the support wheel 25, and the cable is protected by the rubber sleeve 22 while the friction between the pressure wheel 23 and the cable is greatly increased. Then, by starting the servo motor 30, the servo motor 30 rotates to make the rotating shaft 24 drive the support wheel 25 to rotate, and drive the cable to perform the conveying operation through the friction force.

[0061] In order to realize the flattening and straightening treatment before the cable is cut, the pre-straightening component 6 in the present invention includes a mounting groove 12, in which a plurality of light rods 11 are fixed by bolts, a slider 13 is slidably connected between two adjacent light rods 11, a mounting frame 14 is fixed to one side of the slider 13 by bolts, two compression sleeves 15 are fixed to the end of the mounting frame 14 by bolts, the opening directions of the compression sleeves 15 arranged on the two adjacent mounting frames 14 are opposite, a tensioning spring 16 is fixed to one side of the plurality of sliders 13 by bolts, and one end of the tensioning spring 16 is fixed to the stand 3, one end of the retracted cable passes through the middle of the plurality of relatively distributed compression sleeves 15, and then is tensioned by the tensioning spring 16. 16 applies a pulling force to the slider 13, so that the slider 13 drives the compression sleeve 15 on the mounting frame 14 to apply pressure to the cable, and because the plurality of compression sleeves 15 are staggered and relatively distributed, the cable passing therethrough is straightened. The secondary straightening component 9 includes a straightening block 18, and the straightening block 18 is fixed to one side of the stand 3 by bolts. Two straightening holes 17 for secondary flattening of the cable are provided inside the straightening block 18. The pre-straightened cable passes through the straightening hole 17 provided in the straightening block 18, and because the inner diameter of the straightening hole 17 is equal to the outer diameter of the cable, and the straightening hole 17 has a certain length, the cable passing through the straightening hole 17 is further straightened and flattened.

[0062] In order to realize the guiding and positioning of the conveying position of the cable, the adjusting component 8 in the present invention includes a rotating shaft 34, which is rotatably connected to the inside of the stand 3 through an embedded bearing, and one end of the rotating shaft 34 is fixed with a rotating frame 33 by bolts, and a plug block 32 is detachably connected to the rotating frame 33 by screws, and two hole grooves 31 are provided in the plug block 32, and the center line of the hole groove 31 coincides with the center line of the straightening hole 17, and a fixing column 37 is fixed with bolts on the other side of the stand 3, and two force arms 35 are fixed with bolts on the other end of the rotating shaft 34, and the ends of the two force arms 35 are fixed with tension springs 2 36 by bolts, and the ends of the tension springs 2 36 are fixed to the fixing column 37. There is a certain gap between the driving component 5 and the cutting component 4, and the guiding and positioning of the cable during the transportation process of the front driving component 5 and the cutting component 4 must be ensured. The cable will be pulled tightly when it is cut by the cutting component 4, further affecting the guiding accuracy. Therefore, an adjusting component 8 is provided to allow one end of the cable transported through the front driving component 5 to pass through the hole groove 31, so that the cable is guided and positioned, and two tensioning springs 2 36 apply tension to the rotating shaft 3 34 through the force arm 35, so that the rotating frame 33 can not only rotate at an adaptive angle, but also the tension applied by the tensioning springs 2 36 makes the initial position of the rotating frame 33 horizontal, so that it has the function of adaptively adjusting the transportation position of the cable.

[0063] The present invention also provides a cable cutting method, comprising the following steps:

[0064] S1: First, one end of the cable to be cut passes through the middle of the multiple compression sleeves 15 that are relatively staggered, and then the tension spring 16 is tightened to apply tension to the slider 13, so that the slider 13 drives the compression sleeve 15 on the mounting frame 14 to apply pressure to the cable, and because the multiple compression sleeves 15 are relatively staggered, the cable passing through them is straightened;

[0065] S2: The pre-straightened cable then passes through the straightening hole 17 opened by the straightening block 18. Since the inner diameter of the straightening hole 17 is equal to the outer diameter of the cable and the straightening hole 17 has a certain length, the cable passing through the straightening hole 17 is further straightened and flattened.

[0066] S3: The cable straightened by the double leveling process then passes through the front drive assembly 5, the adjustment assembly 8 and the cutting assembly 4 and passes out of the rear drive assembly 1, and the initial position of the rotating frame 33 is horizontal due to the tension applied by the tension spring 2 36 provided in the adjustment assembly 8, thereby adaptively adjusting the delivery position of the cable;

[0067] S4: During transportation, the servo motor 1 30 of the front drive assembly 5 and the rear drive assembly 1 is started, and the servo motor 1 30 rotates to make the rotating shaft 24 drive the supporting wheel 25 to rotate, and the pressing wheel 23 presses the cable passing through the annular groove 26 provided on the supporting wheel 25 through the pressing spring 27, so that the cable is driven to be transported through the friction between the supporting wheel 25 and the cable;

[0068] S5: When cutting, by starting the shear cylinder 56, one end of the piston rod of the shear cylinder 56 extends and drives the upper shear frame 68 and the upper shear knife 69 to move downward. At the same time, through the gear 63, the upper rack 67 moves downward and the lower rack 64 drives the lower shear frame 65 to move upward synchronously, so that the lower shear knife 66 and the upper shear knife 69 arranged on the lower shear frame 65 move toward each other and cut the cable therein through the V-shaped blade 70;

[0069] S6: The cut cable in the rear process is transported through the rear drive assembly 1, while the cable in the front process needs to be reinserted into the shear tool and the rear drive assembly 1 through the front drive assembly 5. Therefore, the finger cylinder 50 provided by the clamping mechanism 38 moves through the clamping arm 49 to clamp the cable with the jacket 48. Since the inner diameter of the jacket 48 provided by the smoothing mechanism 39 is equal to the diameter of the cable, the jacket 48 provided by the smoothing mechanism 39 wraps the cable. Then, by starting the servo motor 2 45, the servo motor 2 45 drives the synchronous pulley 41 to rotate through the synchronous belt. At this time, the synchronous belt drives the smoothing mechanism 39 to move along the guide rail 1 43 to the second position state, so that the jacket 48 provided by the smoothing mechanism 39 moves along the cable to the cut end and rounds it.

[0070] S7: At the same time, when the smoothing mechanism 39 moves and disengages from the photoelectric switch 1 46 in position state 1, the photoelectric switch 1 46 senses and cuts off the power supply of the electromagnetic lock 58. At this time, the lock tongue of the electromagnetic lock 58 retracts and disengages from the locking sleeve 59. At the same time, the smoothing mechanism 39 moves through the extrusion plate 40 to contact and squeeze the force plate 57 provided in the cutting component 4, so that the mounting seat 55 moves along the guide rail 3 61 through the slide table, and avoids the position of the cable end after cutting;

[0071] S8: After the cable end is smoothed, the smoothing mechanism 39 is reset to position state 1. At this time, the cutting component 4 is reset by the reset spring 60, and the photoelectric switch 1 46 senses the reset of the smoothing mechanism 39 and connects the power supply of the electromagnetic lock 58, so that the lock tongue of the electromagnetic lock 58 is extended and re-engaged with the lock sleeve 59, so that the cutting component 4 is fixed;

[0072] S9: Then the clamping mechanism 38 releases the clamping state of the cable, and conveys the cable by starting the front drive component 5, so that the straightened cable passes through the blade of the cutting component 4, and the cable end conveyed from the blade is guided and positioned by the guide conical tube 73, so that the cable is conveyed according to the preset trajectory, and the gap with the rear drive component 1 is reduced by the extension tube 72, so that the cable enters the rear drive component 1. At this time, the rear drive component 1 rotates and re-compresses the cable to form a compressed conveying state, thereby completing the high-precision cutting operation of the cable.

3. A cable cutting method according to any one of claims 1 to 2, It is characterized in that It includes the following steps: S1: First, one end of the cable to be cut passes through the middle of a plurality of relatively staggered compression sleeves (15), and then a tension force is applied to the slider (13) by tightening the tension spring (16), so that the slider (13) drives the compression sleeve (15) on the mounting frame (14) to apply pressure to the cable, and because the plurality of compression sleeves (15) are relatively staggered, the cable passing through them is straightened; S2: The pre-straightened cable then passes through the straightening hole (17) opened by the straightening block (18), and since the inner diameter of the straightening hole (17) is equal to the outer diameter of the cable and the straightening hole (17) has a certain length, the cable passing through the straightening hole (17) is further straightened and flattened; S3: The cable straightened through the double leveling process then passes through the front drive assembly (5), the adjustment assembly (8) and the cutting assembly (4) and passes out from the rear drive assembly (1), and the tension applied by the second tension spring (36) provided in the adjustment assembly (8) makes the initial position of the rotating frame (33) horizontal, thereby adaptively adjusting the conveying position of the cable; S4: During transportation, the servo motor 1 (30) of the front drive assembly (5) and the rear drive assembly (1) is started, and the servo motor 1 (30) rotates to cause the rotating shaft 2 (24) to drive the supporting wheel (25) to rotate, and the pressing wheel (23) is pressed against the cable passing through the annular groove (26) provided on the supporting wheel (25) by the pressing spring (27), so that the cable is driven to be transported by the friction force between the supporting wheel (25) and the cable; S5: When cutting, the shear cylinder (56) is started, and one end of the piston rod of the shear cylinder (56) is extended to drive the upper shear frame (68) and the upper shear knife (69) to move downward. At the same time, the gear (63) causes the upper rack (67) to move downward, and the lower rack (64) drives the lower shear frame (65) to move upward synchronously, so that the lower shear knife (66) and the upper shear knife (69) provided on the lower shear frame (65) move toward each other and cut the cable therein through the V-shaped blade (70); S6: The cut cable in the rear process is transported through the rear drive assembly (1), while the cable in the front process needs to be reinserted into the shearing tool and the rear drive assembly (1) through the front drive assembly (5). Therefore, the finger cylinder (50) provided by the clamping mechanism (38) moves through the clamping arm (49) to clamp the cable with the jacket (48). Since the inner diameter of the jacket (48) provided by the smoothing mechanism (39) is equal to the diameter of the cable, the jacket (48) provided by the smoothing mechanism (39) wraps the cable. Then, by starting the servo motor 2 (45), the servo motor 2 (45) drives the synchronous pulley (41) to rotate through the synchronous belt. At this time, the synchronous belt drives the smoothing mechanism (39) to move along the guide rail 1 (43) to the second position state, so that the jacket (48) provided by the smoothing mechanism (39) moves along the cable to the cut end and rounds it. S7: At the same time, when the smoothing mechanism (39) moves and disengages from the photoelectric switch 1 (46) in position state 1, the photoelectric switch 1 (46) senses and cuts off the power supply of the electromagnetic lock (58), and the lock tongue of the electromagnetic lock (58) retracts and disengages from the locking sleeve (59).

At this time, the cutting component (4) is moved and reset by the reset tension spring (60). At this time, the photoelectric switch 1 (46) senses the reset of the smoothing mechanism (39) and connects the power supply of the electromagnetic lock (58), so that the lock tongue of the electromagnetic lock (58) is extended and re-engaged with the lock sleeve (59), thereby fixing the cutting component (4); S9: The clamping mechanism (38) then releases the clamping state of the cable and starts the front drive assembly (5) to convey the cable, so that the straightened cable passes through the blade of the cutting assembly (4), and the guide conical tube (73) guides and positions the end of the cable conveyed from the blade, so that the cable is conveyed along a preset trajectory, and the extension tube (72) reduces the gap with the rear drive assembly (1), so that the cable enters the rear drive assembly (1).
