Description

Technical Field

[0001] The present invention relates to the technical field of cable pipe production equipment, and specifically relates to a flaring device based on the production of MPP cable pipes. Background Technique

[0002] MPP cable pipes use modified polypropylene as the main raw material. It is a construction project for laying pipelines, cables, etc. in special sections such as roads, railways, buildings, and riverbeds without a large amount of dredging, excavation, and road surface damage. During the production and processing of MPP cable pipes, after the cable pipes are cut and segmented, in order to facilitate subsequent docking, it is necessary to flare one end opening of each group of cable pipes so that each group of cable pipes can be docked with each other. When flaring the cable pipes, a specific flaring device needs to be used for processing.

[0003] When flaring MPP cable pipes, usually the cable pipes are first heated and flared, and then the flaring process is carried out. However, in the existing flaring equipment during processing, it is impossible to clean the impurities on the inner side wall of the end of the cable pipe to be flared. When flaring, if there are more or larger impurities on the inner side wall of the end of the cable pipe to be flared, these impurities are likely to affect the quality of the formed cable pipe after flaring, and in severe cases, it will directly cause damage to the cable pipe. And because the cable pipe is flared after heating, this may cause the flaring punch to adhere to the cable pipe. When separating the flaring punch from the cable pipe, damage occurs at the flared part of the cable pipe, which is not conducive to actual processing. Summary of the Invention

During operation, place the cable pipe body across the upper end of the lower clamping seat at one end of the transmission base, and transmit the cable pipe body through the conveyor chain plate; when the end of the cable pipe body to be flared is aligned with the heating port of the heating device, place the heating device over the end of the cable pipe body to be flared and heat the end of the cable pipe body to be flared.

[0016] 2. After the end of the cable pipe body to be flared is heated, transmit it to directly below the downward pressing assembly through the conveyor chain plate, align the end of the cable pipe body to be flared with the flaring punch; the downward pressing assembly in the clamping mechanism moves downward, and the clamping groove of the clamping pad catches on the upper end of the cable pipe body, and the cable pipe body is clamped and fixed through the cooperation of the downward pressing assembly and the lower clamping seat to prevent shaking and sliding during the flaring of the cable pipe body.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 8, the present invention provides a technical solution: a flaring device for the production of MPP cable pipes, including a transmission base 1. Inside the transmission base 1, a conveyor chain plate 11 is rotatably installed. A plurality of groups of lower clamping seats 12 are fixedly installed at equal intervals on the conveyor chain plate 11. The number of each group of lower clamping seats 12 is two, and the two lower clamping seats 12 in each group are symmetrically distributed front and back. A cable pipe body 13 is placed across the upper ends of the two lower clamping seats 12 in each group. At the upper end of a side plate of the transmission base 1, a reinforcing plate 14 is fixedly installed. Inclined surfaces are provided at both ends of the reinforcing plate 14. An outer support platform 2 is fixedly installed on the outer side of the transmission base 1. The support platform 2 and the reinforcing plate 14 are jointly installed on the outer side and top of a side plate. A front-back moving mechanism is installed at the upper end of the support platform 2. A heating device 25 and a rotary transmission mechanism are respectively installed on the front-back moving mechanism. A flaring punch 4 is installed at one end of the rotary transmission mechanism close to the conveyor chain plate 11. A cleaning mechanism for cleaning the inner wall of one end of the cable pipe body 13 is installed at one end of the flaring punch 4 close to the conveyor chain plate 11.

[0024] An L-shaped positioning baffle is fixedly installed on the outer side of the transmission base 1. By means of the provided L-shaped positioning baffle, one end of the cable pipe body 13 newly placed on the two lower clamping seats 12 is positioned, so that the cable pipe body 13 can be accurately loaded. When loading the cable pipe body 13, it is loaded from one end of the transmission base 1, unloaded at the other end of the transmission base 1, and loaded at the end close to the heating device 25.

[0025] The conveyor chain plate 11 drives a plurality of groups of lower clamping seats 12 to rotate in a cycle, and the conveyor chain plate 11 drives a plurality of groups of lower clamping seats 12 to move intermittently. Each time the conveyor chain plate 11 stops, there will always be a group of lower clamping seats 12 aligned with the flaring punch 4 and the cleaning mechanism. The conveyor chain plate 11 is driven by the output shaft of a stepping motor. Each time the stepping motor starts, the conveyor chain plate 11 advances a certain distance, thereby driving a group of lower clamping seats 12 to move a certain distance. The cable pipe body 13 is driven by the lower clamping seats 12. In this way, the cable pipe body 13 is driven to move from one end of the transmission base 1 to the other end. During this process, the cable pipe body 13 will first be heated by the heating device 25, then be cleaned by the cleaning mechanism and flared by the flaring punch 4, and finally be unloaded.

[0026] Please refer to Figure 1 、 Figure 2 and Figure 4, the front and rear moving mechanism includes an L-shaped transmission plate 22 that is slidably mounted on the upper end of the support table 2 in the front and rear directions. A hydraulic cylinder 24 is fixedly installed on one side of the L-shaped transmission plate 22, and the hydraulic cylinder 24 is fixedly installed on the upper end of the support table 2. A convex groove 21 is formed in the upper end of the support table 2. A convex block 23 is fixedly installed at the lower end of the L-shaped transmission plate 22, and the convex block 23 is slidably connected to the convex groove 21 in the front and rear directions. The heating device 25 is fixedly installed on the side of the L-shaped transmission plate 22 close to the conveyor chain plate 11.

[0027] The number of the hydraulic cylinders 24 can be selected according to needs. When the number of the hydraulic cylinders 24 is two or more, multiple hydraulic cylinders 24 are controlled to expand and contract through an electro-hydraulic closed-loop control system. The electro-hydraulic closed-loop control system includes a servo valve, cross-coupling control, and a displacement sensor. The displacement sensor is used to monitor the positions of the two hydraulic cylinders 24 in real time. After the controller compares the signals, the controller outputs an electrical signal to drive the servo valve, dynamically adjusts the opening of the servo valve, adjusts the flow direction and magnitude to compensate for errors. Cross-coupling control: Bidirectionally couples the synchronization errors of the two hydraulic cylinders 24, and dynamically adjusts the motion commands of the two, so as to realize the synchronous expansion and contraction operation of the two hydraulic cylinders.

[0028] The telescopic movement of the inner rod of the hydraulic cylinder 24 drives the L-shaped transmission plate 22 to move back and forth along the upper end of the support table 2. The L-shaped transmission plate 22 drives the convex block 23 to slide back and forth along the convex groove 21, so that the L-shaped transmission plate 22 can move back and forth stably. When the L-shaped transmission plate 22 moves forward and approaches the conveyor chain plate 11, the L-shaped transmission plate 22 drives the heating device 25, the cleaning mechanism, and the flaring punch 4 to move forward, so that the heating device 25 heats the end to be flared of the cable pipe body 13, and at the same time the cleaning mechanism cleans the end to be flared of the heated cable pipe body 13, and the flaring punch 4 performs a flaring operation on the end to be flared of the heated cable pipe body 13.

[0029] Please refer to Figure 5 , Figure 6 and Figure 8, a rotating circular hole is formed through the side surface of the L-shaped transmission plate 22. The rotating transmission mechanism includes a U-shaped frame 3 fixedly installed on the side surface of the L-shaped transmission plate 22. The U-shaped frame 3 is distributed on the inner side wall of the L-shaped transmission plate 22. A rotating cylinder 31 is rotatably installed in the rotating circular hole. Both ends of the rotating cylinder 31 penetrate through both ends of the rotating circular hole respectively. One end of the rotating cylinder 31 extends to the inner side of the U-shaped frame 3. An external gear ring 32 is fixedly sleeved on the end of the rotating cylinder 31 located inside the U-shaped frame 3. A gear 33 is meshed with the side surface of the external gear ring 32. The gear 33 is driven by the motor shaft of a servo motor fixedly installed on the outer side of the U-shaped frame 3. The motor shaft is rotatably connected to the U-shaped frame 3. The motor shaft and the gear 33 are fixedly sleeved or fixedly connected through a flange or the like. A limiting ring plate 34 is fixedly sleeved on the end of the rotating cylinder 31 close to the conveying chain plate 11.

[0030] The rotating cylinder 31 is rotatably connected to the rotating circular hole through a bearing. The external gear ring 32 and the limiting ring plate 34 are respectively in rotational contact with the two side walls of the L-shaped transmission plate 22. Through the cooperation of the arranged external gear ring 32 and the limiting ring plate 34, the rotating cylinder 31 can rotate stably along the rotating circular hole.

[0031] The motor shaft of the servo motor drives the gear 33 to rotate. The gear 33 drives the external gear ring 32 to rotate. The external gear ring 32 drives the rotating cylinder 31 to rotate along the rotating circular hole. The rotating cylinder 31 drives the limiting ring plate 34 to rotate.

[0032] A plurality of docking insertion rods 35 are fixedly connected in an annular array at one end of the rotating cylinder 31 close to the flaring punch 4. A connecting ring seat 41 is fixedly sleeved on the outer side of one end of the flaring punch 4 close to the rotating cylinder 31. A plurality of docking holes 42 are formed in an annular array at one end of the flaring punch 4 close to the rotating cylinder 31. The number of the docking holes 42 matches the number of the docking insertion rods 35. The docking insertion rods 35 are inserted into the docking holes 42. The inner cavity of the rotating cylinder 31 is communicated with the inner cavity of the flaring punch 4. A fixed connection is provided between the connecting ring seat 41 and the limiting ring plate 34. The fixed connection mode between the connecting ring seat 41 and the limiting ring plate 34 is a detachable connection, such as a bolt connection, a clamping connection or other structures, which can stably lock between the connecting ring seat 41 and the limiting ring plate 34, make the connecting ring seat 41 and the limiting ring plate 34 relatively fixed, and only need to maintain stable synchronous rotation.

[0033] The limiting ring plate 34 rotates to drive the connecting ring seat 41 to rotate. The connecting ring seat 41 drives the flaring punch 4 to rotate.

[0034] The flaring punch 4 rotates while moving forward. By inserting the flaring punch 4 into the end to be flared of the cable pipe body 13 after heating is completed, the flaring operation of the cable pipe body 13 is realized. Since the flaring punch 4 is always in a rotating state, it can effectively prevent the flaring punch 4 from adhering to the inner side wall of the cable pipe body 13, ensuring the quality of the flaring process of the cable pipe body 13.

[0035] Please refer to Figures 4 to 8 , the cleaning mechanism includes a support cross plate 5 arranged in the inner cavity of the flaring punch 4. One end of the support cross plate 5 sequentially passes through one end of the inner cavity of the flaring punch 4, the inner cavity of the rotating cylinder 31 and is fixedly connected to the inner side wall of the C-shaped frame 3. The other end of the support cross plate 5 is fixedly connected with a circular block 51. A blowing and cleaning mechanism is fixedly installed at one end of the flaring punch 4 close to the conveying chain plate 11. The blowing and cleaning mechanism is sleeved on the outer side of the circular block 51. A brush cleaning mechanism that can shake back and forth is installed on the side of the blowing and cleaning mechanism away from the flaring punch 4.

[0036] The blowing and cleaning mechanism includes an annular seat 43 fixedly installed at one end of the flaring punch 4 close to the conveying chain plate 11. An annular cavity 44 is formed on the inner side of the annular seat 43. A plurality of jet nozzles 45 are fixedly installed in an annular array on the side of the annular seat 43 away from the flaring punch 4. An annular sealing cover 53 is fixedly installed on the outer side of the circular block 51. The annular sealing cover 53 is clamped with the inner side of the annular seat 43, and the inner side of the annular seat 43 can rotate along the annular sealing cover 53. The cross section of the annular sealing cover 53 is distributed in an L shape. The annular cavity 44 is sealed through the annular sealing cover 53 and the opening of the annular cavity 44. By setting the annular sealing cover 53 and the annular seat 43, the annular cavity 44 is a sealed cavity. At this time, the gas can only be ejected along the jet nozzles 45, and the jet nozzles 45 are distributed obliquely outward; Symmetrically fixed on the annular sealing cover 53 are connecting air pipes 57. Installation grooves are symmetrically formed on both sides of the support cross plate 5. The two connecting air pipes 57 are respectively installed in the two installation grooves. The two connecting air pipes 57 both penetrate through the C-shaped frame 3 and extend to the outside. The ends of the two connecting air pipes 57 away from the annular sealing cover 53 are jointly connected to a tee joint 56. One port of the tee joint 56 is connected to one end of a hose 55. The other end of the hose 55 is connected to the air outlet end of an air pump 54. The air pump 54 can be installed on the support table 2 or at other positions, which can be selected according to the actual situation as long as it is reasonable.

[0037] The air pump 54 injects gas into the hose 55. The gas flows through the hose 55, passes through the tee joint 56 and enters the two connecting air pipes 57 respectively, then flows into the annular cavity 44 along the two connecting air pipes 57, and finally is ejected along the jet nozzles 45; At this time, if the jet nozzles 45 are in the inner cavity of the cable pipe body 13, the gas ejected by the jet nozzles 45 can clean the impurities attached to the inner side wall of the cable pipe body 13.

[0038] When the flaring punch 4 rotates, it drives the annular seat 43 at its end to rotate synchronously. The annular seat 43 rotates along the annular seal cover 53. At the same time, the annular seat 43 drives the air jet head 45 thereon to rotate synchronously, so that the air jet head 45 can rotate along the inner side wall of the cable pipe body 13, thereby being able to clean the impurities on the inner side wall of the cable pipe body 13 better and more comprehensively.

[0039] The brush cleaning mechanism includes a positioning frame 6 arranged on the side of the annular seat 43 away from the flaring punch 4. Symmetrically fixed to the side of the positioning frame 6 close to the circular block 51 are hemispherical rotating blocks 61. Symmetrically fixed to the side of the circular block 51 close to the positioning frame 6 are hemispherical fixed blocks 52. A plurality of sliding rods 62 are inserted through the side surface of the positioning frame 6 in an annular array. One end of the sliding rod 62 passes through the positioning frame 6 and is fixedly connected to the annular seat 43. The other end of the sliding rod 62 is sleeved with a return spring 63. A retaining ring is fixedly sleeved at the end of the sliding rod 62 away from the annular seat 43. The two ends of the return spring 63 are respectively abutted against the positioning frame 6 and the retaining ring. The return spring 63 exerts an elastic force on the positioning frame 6. The positioning frame 6 is slidably connected to the sliding rod 62. Fixedly connected to the side of the positioning frame 6 away from the circular block 51 is a brush barrel 64. A plurality of soft brush rods are arranged in an annular array on the outer side of the brush barrel 64 which is an annular cylinder.

[0040] The rotation of the annular seat 43 drives the plurality of sliding rods 62 to rotate. The sliding rods 62 drive the positioning frame 6 to rotate. The positioning frame 6 drives the hemispherical rotating blocks 61 and the brush barrel 64 to rotate. The impurities on the inner side wall of the cable pipe body 13 are cleaned by the rotation of the brush barrel 64. When the hemispherical rotating block 61 rotates, the hemispherical rotating block 61 approaches the hemispherical fixed block 52. When the hemispherical rotating block 61 contacts the hemispherical fixed block 52, the hemispherical rotating block 61 continues to rotate. At this time, the hemispherical fixed block 52 pushes the hemispherical rotating block 61 to move away from the circular block 51 until one end of the hemispherical fixed block 52 contacts one end of the hemispherical rotating block 61. At this time, the distance between the hemispherical rotating block 61 and the circular block 51 is the largest. The hemispherical rotating block 61 drives the positioning frame 6 to move away from the circular block 51. The positioning frame 6 drives the brush barrel 64 to move away from the circular block 51. At this time, the positioning frame 6 slides along the sliding rod 62, and at the same time, the positioning frame 6 compresses the return spring 63. When the hemispherical rotating block 61 separates from the hemispherical fixed block 52, under the action of the elastic force of the return spring 63, the positioning frame 6 moves closer to the circular block 51. The positioning frame 6 drives the hemispherical rotating blocks 61 and the brush barrel 64 to move closer to the circular block 51. By moving the hemispherical rotating block 61 closer to and then away from the hemispherical fixed block 52 in a reciprocating manner, the positioning frame 6 drives the brush barrel 64 to move closer to and then away from the circular block 51, so that the brush barrel 64 can vibrate back and forth during rotation, enabling the brush barrel 64 to effectively clean the impurities on the inner wall of the cable pipe body 13.

[0041] Through the cooperation of the set air blowing cleaning mechanism and the brush cleaning mechanism that can vibrate back and forth, the impurities on the inner wall of the cable pipe body 13 can be effectively cleaned, and the cleaning effect is good, effectively preventing the quality of the cable pipe from being affected by impurities after flaring.

[0042] Please refer to Figures 1 to 3 , the upper end of the support table 2 is fixedly installed with an L-shaped support seat 7. The upper end of the L-shaped support seat 7 extends directly above the flaring punch 4. The upper inner side of the L-shaped support seat 7 is equipped with a clamping mechanism for locking the cable pipe body 13.

[0043] The air pump 54 can be installed at the upper end of the L-shaped support seat 7.

[0044] The clamping mechanism includes a pushing component fixedly installed at the upper inner side of the L-shaped support seat 7. One end of the pushing component away from the L-shaped transmission plate 22 is installed with a downward pressing component; The pushing component includes a rectangular cylinder 71 fixedly installed at the upper inner side of the L-shaped support seat 7. A rectangular rod 72 is movably inserted through the inner cavity of the rectangular cylinder 71. One end of the rectangular rod 72 close to the L-shaped transmission plate 22 is fixedly connected to a round rod 73. A buffer spring 74 and an extrusion sleeve 75 are sequentially sleeved on the round rod 73. The two ends of the buffer spring 74 are respectively in contact with the rectangular rod 72 and the extrusion sleeve 75. The extrusion sleeve 75 is slidably connected to the round rod 73. The lower end of the extrusion sleeve 75 is fixedly connected to the upper end of the L-shaped transmission plate 22. One end of the rectangular rod 72 away from the L-shaped transmission plate 22 is rotatably installed with a downward pressing movable arm 8 through a hinge. One end of the downward pressing movable arm 8 away from the rectangular rod 72 is connected to the downward pressing component.

[0045] When the L-shaped transmission plate 22 moves forward closer to the conveyor chain plate 11, the L-shaped transmission plate 22 drives the extrusion sleeve 75 to move synchronously. The extrusion sleeve 75 pushes the buffer spring 74. By compressing the buffer spring 74 with the extrusion sleeve 75, under the elastic force of the buffer spring 74, the rectangular rod 72 is pushed to slide forward along the rectangular cylinder 71. The rectangular rod 72 pushes the downward pressing movable arm 8 to rotate. The lower end of the downward pressing movable arm 8 moves downward. The downward pressing component is driven by the downward pressing movable arm 8 to move downward until the downward pressing component is stuck on the upper end of the cable pipe body 13. The cable pipe body 13 is clamped and fixed by the cooperation of the downward pressing component and the lower clamping seat 12; At this time, the L-shaped transmission plate 22 drives the extrusion sleeve 75 to continue moving forward. At this time, the downward pressing assembly cannot continue to move downward, so that the downward pressing movable arm 8 cannot move downward. At the same time, the rectangular rod 72 and the round rod 73 cannot move forward. At this time, the extrusion sleeve 75 slides along the round rod 73, and the extrusion sleeve 75 presses the buffer spring 74. Under the action of the elastic force of the buffer spring 74, a thrust is applied to the rectangular rod 72, so that the rectangular rod 72 maintains the tendency to move forward. At the same time, the downward pressing movable arm 8 maintains the tendency to move downward, so that the downward pressing assembly is firmly stuck at the upper end of the cable pipe body 13.

[0046] The downward pressing assembly includes an upper clamping seat 81 connected to the lower end of the downward pressing movable arm 8 through a hinge. A clamping pad 82 is fixedly installed at the lower end of the upper clamping seat 81. A clamping groove is opened at the lower end of the clamping pad 82. The clamping groove of the clamping pad 82 is stuck at the upper end of the cable pipe body 13. Symmetrically fixed connections of the upper ends of the upper clamping seat 81 are provided with smooth rods 83. The upper ends of the smooth rods 83 penetrate upward through the upper end of the L-shaped support seat 7 and extend to the outside. A positioning ring and an upper pushing spring 84 are movably sleeved on the upper ends of the smooth rods 83 from top to bottom. The positioning ring is fixedly connected to the upper end of the smooth rod 83. The two ends of the upper pushing spring 84 are respectively abutted against the upper end of the L-shaped support seat 7 and the positioning ring. The upper pushing spring 84 applies an upward thrust to the positioning ring. The smooth rod 83 is slidably connected to the L-shaped support seat 7 up and down.

[0047] The clamping pad 82 is an anti-slip pad with a certain elasticity, so as to protect the cable pipe body 13, prevent damage to the cable pipe body 13 caused by excessive clamping force, and at the same time prevent slipping between the clamping pad 82 and the cable pipe body 13.

[0048] When the lower end of the downward pressing movable arm 8 moves downward, the downward pressing movable arm 8 pushes the upper clamping seat 81 downward. The upper clamping seat 81 drives the clamping groove of the clamping pad 82 to be stuck at the upper end of the cable pipe body 13. At the same time, the upper clamping seat 81 drives the smooth rod 83 to slide downward along the upper end of the L-shaped support seat 7. The smooth rod 83 drives the positioning ring to move downward. At this time, the positioning ring presses the upper pushing spring 84.

[0049] When the L-shaped transmission plate 22 drives the extrusion sleeve 75 to move backward, the extrusion sleeve 75 slides backward along the round rod 73 until the L-shaped transmission plate 22 and the extrusion sleeve 75 are reset; At this time, under the action of the elastic force of the upper pushing spring 84, the positioning ring moves upward. The positioning ring drives the round rod 73 to move upward. The round rod 73 drives the upper clamping seat 81 and the clamping pad 82 to move upward. At the same time, when the lower end of the downward pressing movable arm 8 moves upward, it will drive the upper clamping seat 81 to move upward synchronously, so that the clamping pad 82 releases the clamping and fixing of the cable pipe body 13, so that the upper clamping seat 81 and the clamping pad 82 are reset.

[0050] Working principle: During operation, at one end of the transmission base 1, the cable pipe body 13 is horizontally placed across the upper end of the lower clamping seat 12, and the cable pipe body 13 is transmitted through the conveyor chain plate 11; When the end of the cable pipe body 13 to be flared aligns with the heating port of the heating device 25, the inner rod of the hydraulic cylinder 24 extends to drive the L-shaped transmission plate 22 to move forward. The L-shaped transmission plate 22 drives the heating device 25 to sleeve on the end of the cable pipe body 13 to be flared, and heats the end of the cable pipe body 13 to be flared; after heating is completed, the inner rod of the hydraulic cylinder 24 contracts, and the L-shaped transmission plate 22 drives the heating device 25 to reset.

[0051] After the end of the cable pipe body 13 to be flared is heated, it is transmitted to directly below the downward pressing assembly through the conveyor chain plate 11, so that the end of the cable pipe body 13 to be flared aligns with the flaring punch 4.

[0052] Then, the inner rod of the hydraulic cylinder 24 extends to drive the L-shaped transmission plate 22 to move forward. The L-shaped transmission plate 22 drives the heating device 25, the rotary transmission mechanism, the flaring punch 4, and the cleaning mechanism to move forward. At this time, the cleaning mechanism cleans the inner side wall of the end of the cable pipe body 13 that has just been heated, and then the flaring punch 4 performs a flaring operation on the end of the cable pipe body 13 that has been cleaned; Meanwhile, the heating device 25 heats the end of the next cable pipe body 13 to be flared. When heating one cable pipe body 13, a flaring operation can be performed on another cable pipe body 13 at the same time, greatly improving the working efficiency.

[0053] The specific operation is as follows: When the L-shaped transmission plate 22 moves forward, the L-shaped transmission plate 22 drives the extrusion sleeve 75 to move synchronously. The extrusion sleeve 75 pushes the buffer spring 74, and under the action of the elastic force of the buffer spring 74, the rectangular rod 72 is pushed to slide forward along the rectangular cylinder 71. The rectangular rod 72 pushes the lower end of the downward pressing movable arm 8 downward, and the downward pressing movable arm 8 pushes the upper clamping seat 81 downward. The upper clamping seat 81 drives the clamping groove of the clamping pad 82 to clamp on the upper end of the cable pipe body 13, and the cable pipe body 13 is clamped and fixed through the cooperation of the downward pressing assembly and the lower clamping seat 12 to prevent shaking and sliding during the flaring of the cable pipe body 13; Moreover, the movement of the downward pressing assembly and the flaring punch 4 can be synchronized, and the situation of improper timing control will not occur, that is, the flaring punch 4 flares first, but the cable pipe body 13 has not been clamped yet. At this time, the cable pipe body 13 will move, affecting the accuracy of flaring the cable pipe body 13.

[0054] At this time, the L-shaped transmission plate 22 drives the extrusion sleeve 75 to continue moving forward. At this time, the downward pressing assembly cannot continue to move downward. At this time, the extrusion sleeve 75 slides along the round rod 73, and the extrusion sleeve 75 presses the buffer spring 74. Under the action of the elastic force of the buffer spring 74, a thrust is applied to the rectangular rod 72, so that the rectangular rod 72 maintains a tendency to move forward, and at the same time, the downward pressing movable arm 8 maintains a tendency to move downward, so that the downward pressing assembly is firmly stuck at the upper end of the cable pipe body 13.

[0055] When the L-shaped transmission plate 22 moves forward, the motor shaft of the servo motor drives the gear 33 to rotate. The gear 33 drives the external tooth ring 32 to rotate. The external tooth ring 32 drives the limit ring plate 34 to rotate through the rotating cylinder 31. The limit ring plate 34 drives the flaring punch 4 to rotate through the connecting ring seat 41. The flaring punch 4 drives the cleaning mechanism to rotate, and at the same time, the air pump 54 is started; When the cleaning mechanism is inserted into the inner cavity of the to-be-flared end of the cable pipe body 13, through the cooperation of the brush cleaning mechanism and the air blowing cleaning mechanism, the impurities on the inner side wall of the cable pipe body 13 can be well cleaned, and the cleaning effect is good, effectively preventing the quality of the cable pipe from being affected by impurities after flaring, and cleaning the inner side wall of the to-be-flared end of the cable pipe body 13.

[0056] Both the air blowing cleaning mechanism and the brush cleaning mechanism rotate synchronously with the flaring punch 4. The annular seat 43 in the air blowing cleaning mechanism drives the jet head 45 thereon to rotate, so that the jet head 45 can rotate along the inner side wall of the cable pipe body 13; the brush barrel 64 in the brush cleaning mechanism rotates along the inner side wall of the cable pipe body 13, and at the same time, the brush barrel 64 can shake back and forth during the rotation process, so as to better and more comprehensively clean the impurities on the inner side wall of the cable pipe body 13.

[0057] After the impurities on the inner side wall of the cable pipe body 13 are cleaned, the flaring punch 4 is inserted into the to-be-flared end of the heated cable pipe body 13, so as to realize the flaring operation of the cable pipe body 13; Since the flaring punch 4 is always in a rotating state, it can effectively prevent the situation that the flaring punch 4 adheres to the inner side wall of the cable pipe body 13, and ensure the quality of the flaring processing of the cable pipe body 13.

[0058] After the flaring processing of one cable pipe body 13 is completed, and at the same time the heating of another cable pipe body 13 is completed. At this time, the inner rod of the hydraulic cylinder 24 contracts to drive the L-shaped transmission plate 22 to move backward. The L-shaped transmission plate 22 drives the heating device 25, the rotary transmission mechanism, the flaring punch 4 and the cleaning mechanism to move backward for resetting; When the L-shaped transmission plate 22 drives the extrusion sleeve 75 to move backward, the extrusion sleeve 75 slides backward along the round rod 73 until the L-shaped transmission plate 22 and the extrusion sleeve 75 are reset; At this time, under the action of the elastic force of the upward pushing spring 84, the positioning ring moves upward. The positioning ring drives the round rod 73 to move upward, and the round rod 73 drives the upper clamping seat 81 and the clamping pad 82 to move upward. At the same time, when the lower end of the pressing movable arm 8 moves upward, it will drive the upper clamping seat 81 to move upward synchronously, so that the clamping pad 82 releases the clamping and fixing of the cable pipe body 13, so that the upper clamping seat 81 and the clamping pad 82 are reset and wait for the next clamping operation.

[0059] At this time, the conveyor chain plate 11 runs again to move the cable pipe body 13 with the flaring completed from below the pressing component, transport the newly heated cable pipe body 13 to below the pressing component, and at the same time transport the unheated cable pipe body 13 to align with the heating port of the heating device 25, and then perform the above operations. In this way, the cable pipe body 13 can be continuously processed. When the cable pipe body 13 is transported to the other end of the transmission base 1, the cable pipe body 13 with the flaring completed can be unloaded.

The scope of the present invention is defined by the appended claims and their equivalents.
