Description

Technical Field

[0001] The present invention relates to the technical field of cable protection pipe production, and specifically relates to a flaring tool for cable protection pipe production. Background Art

[0002] A cable protection pipe refers to a protective pipe with a certain mechanical strength that is laid on the outer layer of a cable to prevent the cable from being damaged. When the cable protection pipe enters a cable trench (tunnel) or a cable well, in order to protect the outer protective layer of the cable from being cut by the pipe orifice, it is generally required to expand the pipe orifice.

[0003] For example, in a Chinese patent with the publication number CN213593627U and the name "A Flaring Device for Cable Protection Pipe Production", it includes a frame, a flaring assembly, a pressing assembly, an inclined feeding table, a cable protection pipe, and a control device arranged on the frame. A heating assembly is arranged on one side of the pressing assembly close to the flaring assembly. The pressing assembly, the flaring assembly, and the heating assembly are all electrically connected to the control device. In practical applications, the cable protection pipe to be flared rolls into the pressing assembly from the inclined feeding table. The control device controls the pressing assembly to press the cable protection pipe to be flared, heats the cable protection pipe to be flared through the heating assembly, flares the heated cable protection pipe through the flaring assembly, and after the flaring is completed, the flared cable protection pipe can be taken out by loosening the pressing assembly. The utility model is convenient for loading and unloading, has uniform flaring thickness of pipe fittings, good flaring effect, and high production efficiency.

[0004] Although the above-mentioned flaring device for cable protection pipe production in the above patent is practical and convenient, it also has deficiencies. The above patent can only flare one end of one cable protection pipe at a time, and cannot flare both ends of a batch of cable protection pipes cyclically, with low working efficiency and unable to meet the requirement of flaring both ends of the protection pipe.

The cable protection pipe with one end already flared is transported into the transfer table, and the first clamping member clamps the cable protection pipe with one end already flared that is closest to each other in the transfer table. During the movement of the first clamping member, the flaring column and the heating sleeve slide synchronously through the second transmission component to respectively expand the holes and heat the two corresponding cable protection pipes on the synchronous belt. During the reverse movement of the first clamping member, the first clamping member drives the clamped cable protection pipe with the rotated end already flared to rotate 180° through the adjustment component. When the synchronous belt rotates intermittently, the other end of the cable protection pipe with one end already flared can undergo subsequent heating and flaring processes. During the reverse movement of the first clamping member, secondary hole expansion and secondary heating are performed through the second transmission component to improve the hole expansion effect and heating efficiency. The overall device has high working efficiency and can continuously operate to flare both ends of a batch of cable protection pipes. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Please refer to Figures 1-8 , a technical solution provided by an embodiment of the present invention: The flaring device for producing a cable protection pipe includes a base 1, a first transmission component, an adjustment component, and a second transmission component. A synchronous belt 10 is intermittently rotatably connected to the base 1. A plurality of positioning members for positioning the cable protection pipe are equidistantly arranged on the synchronous belt 10. A flaring column 45 and a heating sleeve 44 are synchronously slidably connected to the base 1. Above the synchronous belt 10, a first clamping member and a second clamping member are synchronously reciprocatingly slidably connected. A transfer table 46 is provided on the base 1. The first transmission component is driven by the sliding of the first clamping member to intermittently rotate the synchronous belt 10. During the sliding of the first clamping member, the first clamping member is rotated by the adjustment component. The second transmission component is driven by the sliding of the first clamping member to synchronously slide the flaring column 45 and the heating sleeve 44. Specifically, one end of the flaring column 45 facing the positioning member is frustum-shaped, which is convenient for flaring the cable protection pipe. A first fixing plate 2 and a second fixing plate 3 are fixedly connected to the base 1. A driving roller 8 and a driven roller 9 are rotatably connected between the first fixing plate 2 and the second fixing plate 3. The synchronous belt 10 is rotatably sleeved on the circumferential sides of the driving roller 8 and the driven roller 9.

[0029] As a preferred technical solution, the first transmission assembly includes a first gear 7 and a first irregular gear 6 meshing with the first gear 7. The first gear 7 and the first irregular gear 6 are rotatably connected to one side of the first fixing plate 2, and one end of the first gear 7 is coaxially and fixedly connected to one end of the driving roller 8. A support plate 4 is fixedly connected to one side of the first fixing plate 2, and a motor 5 is provided on the support plate 4. The output end of the motor 5 is coaxially and fixedly connected to the first irregular gear 6. Specifically, when the motor 5 is started, the motor 5 drives the first irregular gear 6 to rotate. When the first irregular gear 6 meshes with the first gear 7, the synchronous belt 10 rotates a certain distance. When the first irregular gear 6 does not mesh with the first gear 7, the synchronous belt 10 stops rotating.

[0030] As a preferred technical solution, the other end of the first irregular gear 6 is coaxially and fixedly connected to a rotating rod 12. Two helical grooves 13 connected end to end are formed on the rotating rod 12. A moving plate 11 is reciprocally slidably connected to the rotating rod 12. A protrusion 14 is provided in the moving plate 11. Both helical grooves 13 are slidably engaged with the protrusion 14. A first guide rod 15 is horizontally arranged on the other side of the first fixing plate 2. The moving plate 11 is slidably sleeved on the first guide rod 15. A first connecting block 16 is provided on the side of the moving plate 11 close to the first clamping member. A connecting rod 17 is provided between the first clamping member and the first connecting block 16. The connecting rod 17 is rotatably connected to one side of the first connecting block 16. Specifically, the first irregular gear 6 drives the rotating rod 12 to rotate. Through the sliding cooperation between the protrusion 14 and the two helical grooves 13, and at the same time, the first guide rod 15 restricts the circumferential rotation of the moving plate 11, so that the moving plate 11 drives the first clamping member to reciprocally slide through the first connecting block 16 and the connecting rod 17.

[0031] As a preferred technical solution, the adjusting assembly includes a second bracket 27, a first rack 28, and a second gear 18 meshing with the first rack 28. The second gear 18 is sleeved on the connecting rod 17. The second bracket 27 is fixedly connected to the base 1. The first rack 28 is horizontally and fixedly connected to the top of the second bracket 27. During the sliding process of the first clamping member, the first rack 28 has a meshing position meshing with the second gear 18. Specifically, after the first clamping member moves into the transfer table 46 and clamps a cable protection pipe with one end flared, during the process of moving towards the synchronous belt 10, through the meshing rotation between the second gear 18 and the first rack 28, the first clamping member drives the clamped cable protection pipe to rotate 180 degrees, so that the other end of the clamped cable protection pipe can undergo the next heating and reaming processes, and the two ends of the cable protection pipe can be flared, which can meet the needs of society.

[0032] As a preferred technical solution, the second transmission assembly includes a push rod 33, a first spring 35, a slider 36, an abutting block 38, a second guide rod 40, a second spring 41, a second connecting block 42 and a third connecting block 43. A first chute 34 and a second chute 37 which is perpendicular to and communicates with the first chute 34 are formed in the second fixing plate 3. The push rod 33 and the slider 36 are horizontally slidably connected in the first chute 34, and the abutting block 38 and the second connecting block 42 are horizontally slidably connected in the second chute 37. The push rod 33 penetrates through one end of the slider 36. The first spring 35 is sleeved on the push rod 33, and two ends of the first spring 35 are respectively fixedly connected with one end of the slider 36 close to the push rod 33 and the inner wall of the first chute 34. The other end of the slider 36 is slidably abutted against one end of the abutting block 38. The abutting block 38 is slidably sleeved on the second guide rod 40. The second guide rod 40 is horizontally and fixedly connected in the second chute 37. The second spring 41 is sleeved on the second guide rod 40, and two ends of the second spring 41 are respectively fixedly connected with the other end of the abutting block 38 and the inner wall of the second chute 37. The second connecting block 42 is arranged between the bottom of the third connecting block 43 and the top of the abutting block 38. Two ends of the third connecting block 43 are respectively fixedly connected with the heating sleeve 44 and the flaring column 45. One end of the abutting block 38 close to the slider 36 is inclined. One end of the push rod 33 close to the first connecting block 16 is conical. The first connecting block 16 is slidably abutted and matched with the end of the push rod 33 far from the slider 36. Specifically, a guide hole 39 is formed in the abutting block 38, and the abutting block 38 is slidably sleeved on the second guide rod 40 through the guide hole 39. During the process that the moving plate 11 drives the first connecting block 16 to move towards the transfer table 46, since one end of the push rod 33 close to the first connecting block 16 is conical and the first connecting block 16 is slidably abutted against the push rod 33, the push rod 33 can be driven to drive the slider 36 to move towards the abutting block 38. Also, since one end of the abutting block 38 close to the slider 36 is inclined, the abutting block 38 can drive the heating sleeve 44 and the flaring column 45 to move towards the first fixing plate 2 through the second connecting block 42 and the third connecting block 43, so as to heat and flare the two cable protection pipes respectively. When the first connecting block 16 is not in contact with the push rod 33, the slider 36 slides reversely through the elastic deformation of the first spring 35. During the reverse sliding process of the slider 36, the abutting block 38 drives the heating sleeve 44 and the flaring column 45 to slide reversely through the elastic deformation of the second spring 41 through the second connecting block 42 and the third connecting block 43. During the process that the moving plate 11 drives the first connecting block 16 to move towards the first fixing plate 2, the two cable protection pipes can be heated and flared for the second time respectively, improving the flaring effect and the heating efficiency.

[0033] As a preferred technical solution, each positioning member includes a connecting plate 29, a cylinder 30, a first positioning groove 31 and a second positioning groove 32. The connecting plate 29 is arranged on the synchronous belt 10. The cylinder 30 is horizontally and fixedly connected to one side of the connecting plate 29. The first positioning groove 31 and the second positioning groove 32 are both opened on one side of the connecting plate 29, and the inner diameter and outer diameter of the first positioning groove 31 are both smaller than those of the second positioning groove 32. Specifically, the inner diameter of the cylinder 30 is adapted to that of the cable protection pipe, the cable protection pipe is sleeved on the cylinder 30, and the non-flared end of the cable protection pipe is clamped and fitted in the first positioning groove 31, while the flared end of the cable protection pipe is clamped and fitted in the second positioning groove 32. Preferably, after one end of the cable protection pipe is flared, the overall length of the cable protection pipe is shortened, and the depth of the first positioning groove 31 is deeper than that of the second positioning groove 32, which can ensure that the heating and flaring degrees at both ends are the same.

[0034] As a preferred technical solution, the first clamping member includes an L-shaped first clamping block 19, a first clamping plate 20, a rotating shaft 21 and a torsion spring 22. One side of the first clamping block 19 is fixedly connected to one end of the connecting rod 17. The rotating shaft 21 is arranged in the first clamping block 19. The first clamping plate 20 is rotatably sleeved on the rotating shaft 21. The torsion spring 22 is arranged between the first clamping plate 20 and the rotating shaft 21, and the torsion spring 22 is sleeved on the rotating shaft 21. Specifically, the clamping of the cable protection pipe is realized through the elastic deformation of the torsion spring 22. And when the first clamping member sleeves the cable protection pipe with one end already flared on the corresponding cylinder 30, the first irregular gear 6 meshes with the first gear 7, so that the cable protection pipe moves horizontally, and the first clamping plate 20 rotates through extrusion. When the cable protection pipe is released from the clamping, the first clamping plate 20 is reset through the elastic deformation of the torsion spring 22. Preferably, when the first clamping plate 20 and the first clamping block 19 move towards the transfer table 46, one side of the first clamping plate 20 and the first clamping block 19 is inclined, which is convenient for clamping the cable protection pipe.

[0035] As a preferred technical solution, the second clamping member includes an L-shaped second clamping block 24, a second clamping plate 25, and a second irregular gear 26. The second irregular gear 26 is horizontally rotatably connected to the bottom end of the second clamping block 24, and the second clamping plate 25 is fixedly connected and integrally formed with the second irregular gear 26. The top of the second clamping block 24 and one side of the first connecting block 16 are respectively fixedly connected to both ends of the first bracket 23. Specifically, a transfer groove 48 is formed in the transfer table 46, and a second rack 47 engaged with the second irregular gear 26 is horizontally arranged in the transfer groove 48. When the synchronous belt 10 rotates, the cable protection pipe closest to the second clamping member is squeezed into the space between the second clamping block 24 and the second clamping plate 25 through the positioning member. The first connecting block 16 drives the second clamping block 24 and the second clamping plate 25 to move through the first bracket 23. The second clamping block 24 and the second clamping plate 25 drive the clamped cable protection pipe to move towards the transfer table 46. Through the engagement between the second irregular gear 26 and the second rack 47, the second clamping plate 25 is driven to rotate, releasing the clamping force on the lower part of the clamped cable protection pipe. The clamped cable protection pipe rolls into the transfer groove 48 by its own gravity, facilitating subsequent clamping and transfer by the second clamping member. A first through hole 49 and a second through hole 50 communicating with the transfer groove 48 are formed in the transfer table 46. The first through hole 49 and the second through hole 50 are provided to adapt to the first clamping member and the second clamping member, avoiding hindering the movement strokes of the first clamping member and the second clamping member.

[0036] Working principle: When starting the motor 5 of the flaring tool for cable protection pipe production, the motor 5 drives the first irregular gear 6 to rotate. When the first irregular gear 6 meshes with the first gear 7, the synchronous belt 10 rotates, driving the horizontal displacement of the cable protection pipe between the first clamping block 19 and the first clamping plate 20. Through extrusion, the first clamping plate 20 rotates, causing the cable protection pipe to break away from the clamping. At the same time, the cable protection pipe closest to the second clamping member is extruded between the second clamping block 24 and the second clamping plate 25 through the positioning member. When the first irregular gear 6 does not mesh with the first gear 7, the synchronous belt 10 does not rotate, and the first clamping member and the second clamping member hold the cable protection pipe with one end already flared and move towards the transfer table 46 at the same time. Through the meshing between the second irregular gear 26 and the second rack 47, the second clamping plate 25 rotates, releasing the clamping force on the lower part of the clamped cable protection pipe. The clamped cable protection pipe rolls into the transfer groove 48 by its own gravity, facilitating the subsequent clamping and transfer by the second clamping member. The first clamping member clamps the cable protection pipe with one end already flared that is closest to each other in the transfer table 46 through the elastic deformation of the torsion spring 22. During the process of the moving plate 11 moving towards the transfer table 46, the first connecting block 16 slides and abuts against the push rod 33, enabling the push rod 33 to drive the slider 36 to move towards the abutting block 38, enabling the abutting block 38 to drive the heating sleeve 44 and the flaring column 45 towards the first fixing plate 2 through the second connecting block 42 and the third connecting block 43, heating and flaring the two cable protection pipes respectively. When the first connecting block 16 does not contact the push rod 33, the slider 36 slides in the reverse direction through the elastic deformation of the first spring 35. During the reverse sliding process of the slider 36, the abutting block 38 drives the heating sleeve 44 and the flaring column 45 to slide in the reverse direction through the elastic deformation of the second spring 41. During the reverse movement of the moving plate 11, through the meshing rotation between the second gear 18 and the first rack 28, the first clamping member drives the clamped cable protection pipe to rotate 180 degrees, enabling the other end of the clamped cable protection pipe to undergo the next heating and reaming processes, achieving flaring of both ends of the cable protection pipe, meeting the needs of society. At the same time, the two cable protection pipes can be reamed and heated for the second time, improving the reaming effect and heating efficiency. The overall device has high working efficiency and can continuously operate to flare both ends of a batch of cable protection pipes.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
