Description

Technical Field

[0001] This utility model relates to the field of corrugated roll forming machine technology, specifically a movable outer tube corrugated roll forming machine. Background Technology

[0002] Cables are typically rope-like cables made up of several or groups of conductors (at least two conductors per group) twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being energized internally and insulated externally. When corrugating the outer tube of a cable, an outer tube corrugating machine is used.

[0003] Referring to patent publication number "CN102248051B", a corrugated pipe outer conductor rolling device is disclosed. Its features are mainly composed of a rolling base, a blade holder, an angle adjuster, and a depth adjuster. The rolling base is annular, and a blade holder is rotatably provided in the middle of the annulus. A rolling cutter is provided on the blade holder. One end of the blade holder is connected to the angle adjuster, and the other end of the blade holder is connected to the depth adjuster. The rolling base is provided with a balance adjustment groove. The balance adjustment groove is two arc-shaped grooves with steps, which are symmetrically arranged on both sides of the annulus of the rolling base.

[0004] As shown in the above technology, when producing cables using an outer tube corrugating machine, the cable is in a moving state. The part inside the corrugating machine is under pressure, while the part coming out of the corrugating machine is no longer under pressure. As a result, the cable on the outside may sway irregularly, thus affecting subsequent processing. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The mobile outer tube corrugating mill offers two technical solutions:

[0026] The first implementation includes a base 1, with a slide rail 2 fixedly mounted on the top of the base 1. A movable seat 3 is slidably connected to the slide rail 2, and front and rear corrugating seats are mounted on the movable seat to achieve double support. A motor is mounted on the movable seat 3 and drives the corrugating head to rotate via a synchronous belt. A corrugating cutter is mounted on the corrugating head, and the corrugation of the pipe is achieved by the rotation of the corrugating cutter. The depth of the corrugation is electrically adjustable. A feed motor drives a threaded shaft to move back and forth via a pair of gears. A slanted feed cutter is mounted on the threaded shaft, and the back and forth movement of the slanted block causes the corrugating cutter to move up and down, thereby achieving the corrugation. The depth of the corrugation is determined by a pull-rope type sensor encoder installed between the moving seat and the fixed seat, which can detect the position of the moving seat on the fixed seat in real time. The smooth round tube is electrically fed into the corrugating machine by an independent traction machine from the previous process. The rotation of the corrugating machine and the traction machine are electrically synchronized through the pull-rope sensor encoder, which fully ensures the stability of the corrugation pitch, with low resistance and a beautiful and stable corrugation appearance without scratching the surface. The right side of the moving seat 3 is equipped with a support and stabilization mechanism for stabilizing the outer tube. The support and stabilization mechanism includes an adjustment component 4 and a vibration damping component 5.

[0027] The adjustment assembly 4 includes a fixed block 41, which is fixedly connected to the right side of the movable seat 3. The top of the fixed block 41 has two sliding grooves 42, and a bidirectional threaded rod 43 is rotatably connected between opposite sides of the inner walls of the two sliding grooves 42. The surface of the bidirectional threaded rod 43 is threadedly connected to two support rods 44, and the top of the two support rods 44 is fixedly connected to a sliding seat 46. The inner surface of the sliding seat 46 is slidably connected to a sliding rod 47, and one end of the sliding rod 47 is mounted with an arc plate 48 through the mounting assembly 6. The other end of the sliding rod 47 is connected to the support rod 44 through the vibration damping assembly 5. The two support rods 44 are slidably connected to the inner surfaces of the two sliding grooves 42 respectively. The back of the fixed block 41 is fixedly connected to an adjustment motor 45, and the output end of the adjustment motor 45 is fixedly connected to one end of the bidirectional threaded rod 43.

[0028] The vibration damping assembly 5 includes a first U-shaped seat 51 and a second U-shaped seat 52. The first U-shaped seat 51 is fixedly connected to one side of the support rod 44, and the second U-shaped seat 52 is fixedly connected to the other end of the slide rod 47. A first circular plate 53 is rotatably connected inside the first U-shaped seat 51. A damper 54 is fixedly connected to one side of the first circular plate 53, and a second circular plate 55 is fixedly connected to the telescopic end of the damper 54. A vibration damping spring 56 is sleeved on the surface of the damper 54 between the damper 54 and the second circular plate 55. A guide rod 59 is fixedly connected between the left and right sides of the inner wall of the second U-shaped seat 52. A connecting block 57 is fixedly connected to the other side of the second circular plate 55, and a guide groove 58 is opened inside the connecting block 57. The guide rod 59 passes through the inside of the guide groove 58.

[0029] When the outer tube corrugation is completed and it comes out of the corrugating machine, the support and stabilization mechanism clamps and stabilizes both sides of the outer tube, thereby keeping the outer tube stable during movement and reducing the impact on subsequent processing. Furthermore, when the outer tube rotates irregularly while being clamped by the arc plate, the vibration damping component 5 dampens the outer tube, ensuring stability and improving the practicality of the device.

[0030] The second embodiment differs from the first embodiment in that the mounting assembly 6 includes two fixing bolts 61 and a fixing sleeve 62. The two fixing bolts 61 are fixedly connected to the top and bottom of the slide rod 47, and the fixing sleeve 62 is fixedly connected to the outer side of the arc plate 48. The top and bottom of the fixing sleeve 62 are provided with U-shaped grooves 64, and a positioning groove 65 is provided in the middle of the U-shaped groove 64. The surfaces of the two fixing bolts 61 are threaded with locking nuts 63. Rotating the locking nuts 63 causes the locking nuts 63 to enter the positioning groove 65 to install and fix the arc plate 48.

[0031] The arc plate 48 is mounted on one end of the slide rod via the mounting assembly 6. When dealing with outer tubes of different sizes and with different corrugations, the appropriate arc plate 48 can be quickly replaced, improving the applicability of the device.

[0032] In use, after the outer tube corrugated section is machined, the adjusting motor 45 is started to rotate the bidirectional threaded rod 43. The rotation of the bidirectional threaded rod 43 drives the two support rods 44 to move closer to each other, thereby bringing the arc plate 48 closer to both sides of the outer tube and aligning the limiting strip 481 with the threads on the surface of the outer tube. This process needs to be carried out slowly. After alignment, the limiting strip 481 enters the corrugations of the outer tube and maintains contact. The vibration generated during the rotation and movement of the outer tube is transmitted to the arc plate 48 and then to the slide rod 47. The slide rod 47 slides, at which point the guide rod 59 contacts the inner wall of the guide groove 58, thereby causing the damper 54 to extend and retract. The damper 54 absorbs the force generated by the vibration and resets it through the damping spring 56, thus ensuring the stability of the outer tube. In addition, when it is necessary to stabilize the outer tube of different sizes, rotate the two locking nuts 63. The locking nuts 63 rotate and come out of the positioning groove 65, at which point the arc plate 48 can be removed.
