Description

Technical Field

[0001] The present invention relates to the field of cable production, and in particular to a cable armor forming and processing device. Background Art

[0002] Armoured cable is a type of power or communication cable that has an additional protective layer to increase the cable's resistance to mechanical damage. The cable's name comes from the "armour" covering it, which is usually made of braided metal tape or wire to provide additional strength and protection.

[0003] Traditionally, armored cable production involves wrapping metal tape around the outer wall of the cable core using a cable armoring machine. Current thick cable armoring processes require the use of a double layer of tape, with one layer wound in a spiral and the other layer covering the gaps between the previous layers, also wrapped in a spiral.

[0004] However, after the double-layer tape is wound, the two layers of tape are simply overlapped and fixed to each other, and the tapes cannot be tightly connected. During the subsequent cable winding process, the tapes will slip relative to each other or even bulge, affecting the stability of the armor layer, which needs to be improved. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a cable armor forming and processing device, which has the effect of improving the stability of the armor layer.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A cable armor forming and processing device, comprising:

[0008] Threading pipes are horizontally arranged at both ends of the machine base and are used for threading cables;

[0009] The armoring mechanism includes a support frame, an unwinding reel, a guide pulley, and a strip discharging head. The support frame is horizontally rotatably connected to the machine base and allows the cable to be horizontally passed through. A pair of unwinding reels are rotatably arranged on both sides of the support frame. The guide pulley is rotatably connected to the support frame and allows the metal strip to cross over. The strip discharging head is arranged at an end position of the support frame and allows the metal strip to pass through.

[0010] The press-fitting mechanism includes a press-fitting tube, a wheel frame and a press wheel. The cross-section of the press-fitting tube is rectangular and is used for the metal strip to pass through. The wheel frame is arranged on both sides of the press-fitting tube. The press wheel is rotatably connected to the wheel frame and is located inside the press-fitting tube. The top wall of the press-fitting tube is provided with a press groove for the edge position of the press wheel to be embedded.

[0013] In a preferred example, the present invention can be further configured as follows: a cleaning pipe for the metal strip to pass through is provided at the discharge position of the unwinding reel.

[0017] In a preferred example, the present invention can be further configured as follows: the outlet position of the oil coating box is horizontally rotatably connected to a coating pipe for the cable to pass through.

[0018] In a preferred example, the present invention can be further configured as follows: a pair of spirally arranged brushes are provided on the inner wall of the coating tube, and the brushes are arranged in a step-like manner and respectively contact the inner and outer metal strips.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 、 Figure 2 、 Figure 3 As shown, a cable armor forming and processing device includes a machine base 1, a threading tube 2, an armoring mechanism 3 and a pressing mechanism 4.

[0033] like Figure 1 As shown, the machine base 1 is set on the ground, and the wire threading pipes 2 are horizontally arranged at both ends of the machine base 1 for the cables to pass through.

[0034] like Figure 2 、 Figure 3 As shown, the armoring mechanism 3 includes a support frame 31, an unwinding reel 32, a guide pulley 33, and a strip delivery head 34. The support frame 31 is horizontally rotatably connected to the machine base 1 and allows the cable to be passed horizontally. A pair of unwinding reels 32 are rotatably mounted on either side of the support frame 31. The guide pulley 33 is rotatably connected to the support frame 31 and allows the metal strip to pass over it. The strip delivery head 34 is located at the end of the support frame 31 and allows the metal strip to pass through.

[0035] like Figure 3 、 Figure 4 As shown, the press-fitting mechanism 4 comprises a press-fitting tube 41, a wheel frame 42, and a pressing wheel 43. The press-fitting tube 41 has a rectangular cross-section and is used to thread the metal strip. The wheel frames 42 are positioned on either side of the press-fitting tube 41. The pressing wheel 43 is rotatably connected to the wheel frames 42 and positioned within the press-fitting tube 41. The top wall of the press-fitting tube 41 is provided with a pressing groove 44 into which the edge of the pressing wheel 43 is inserted.

[0036] like Figure 3 、 Figure 4 As shown, a gantry 45 spanning the wheel frame 42 is provided on the press-fitting tube 41, and the wheel frame 42 is vertically slidably connected to the gantry 45. A screw 46 is threadedly connected to the gantry 45, and the screw 46 is rotatably connected to the wheel frame 42.

[0037] like Figure 1 、 Figure 5 As shown, the tail portion of the threading tube 2 at the rear is rotatably connected to an extrusion ring 5 , an inner wall of the extrusion ring 5 is provided with a pressing block 51 , and a spiral groove 52 is provided on the pressing block 51 .

[0038] When the cable needs to be armored, the cable core is passed through the two threading tubes 2 and the support frame 31, and the cable core is pulled slowly. The metal strip is then passed over the guide pulley 33 and then through the strip head 34. The metal strip is then passed through the press tube 41, and the screw 46 is controlled to rotate, causing the wheel frame 42 to drive the pressing wheel 43 to slide inward, causing the pressing wheel 43 to press on both sides of the metal strip to form stamped ridges, which then fit into the pressing groove 44.

[0039] Then fix the metal strip to the outer wall of the cable core and control the support frame 31 to rotate. At this time, as the cable core slides and the support frame 31 rotates, the metal strip will be automatically pulled out, and ridges will be automatically pressed out on both sides of the metal strip. At the same time, the metal strip is wrapped around the outer wall of the cable core.

[0040] During the winding process, the inner metal strip is spirally wound around the outer wall of the cable core, with convex ridges formed on both sides. Simultaneously, the outer metal strip is wrapped around the gaps in the inner metal strip, and the ridges on the inner and outer metal strips engage with each other, thus achieving winding of the armor layer and a stable connection between the armor layers.

[0041] Finally, the inner core of the cable with the armor layer passes through the extrusion ring 5, so that the raised ridges on the outside of the armor layer are embedded in the card groove 52 on the pressure block 51. As the extrusion ring 5 rotates, the pressure block 51 automatically presses the ridges at the card connection positions of the inner and outer metal strips together to complete the stable processing of the armor layer.

[0042] Therefore, by arranging a pressing mechanism 4 behind the armoring mechanism 3, convex and concave ridges can be pressed out on both sides of the inner and outer metal strips, and in the process of mutual winding and lamination of the inner and outer metal strips, the ridges on the inner and outer strips are clamped and fixed to each other, thereby achieving fixation between the double-layer strips and improving the stability of the armor layer.

[0043] At the same time, by providing a rotating extrusion ring 5 and arranging a pressure block 51 with a card slot 52 in the extrusion ring 5, the armor layer can pass through the extrusion ring 5, and the convex ridges on the inner and outer layers of the belt sheet that are engaged with each other are embedded in the card slot 52, thereby realizing the extrusion of the inner and outer layers of the belt sheet, making the armor layer more stably connected together, thereby improving the stability of the armor layer.

[0044] like Figure 3 、 Figure 6 As shown, a cleaning tube 6 for the metal strip to pass through is installed at the discharge position of the unwinding reel 32. The cleaning tube 6 comprises a fixed tube 61, a movable tube 62, and a cotton cloth 63. The fixed tube 61 and the movable tube 62 are both C-shaped and interlocked. The cotton cloth 63 is attached to the inner walls of the fixed tube 61 and the movable tube 62. Hooks 64 are installed at both ends of the fixed tube 61, and a hole 65 is provided on the movable tube 62 for the hooks 64 to pass through.

[0045] When the metal strip is unwound, it passes through the cleaning tube 6, automatically wiping away impurities on its surface. After using the cleaning tube 6 for a period of time, the hook 64 is pressed out of the locking hole 65 to separate the fixed tube 61 and the movable tube 62, making it easier to remove and replace the cotton cloth 63. The fixed tube 61 and the movable tube 62 are then fastened together, and the hook 64 is inserted into the locking hole 65, completing the installation of the cleaning tube 6 and allowing for continued use.

[0046] like Figure 1 、 Figure 7As shown, an oiling box 7 is provided at the rear of the machine base 1, and upper guide wheels 71 are provided on the upper side walls on both sides of the oiling box 7, and lower guide wheels 72 are provided on the lower side walls. The cable crosses the upper guide wheel 71 and the lower guide wheel 72, and is located in the oiling box 7 in a U shape.

[0047] like Figure 7 As shown, the lower guide wheel 72 is vertically slidably connected to the oiling box 7, and a lead screw 73 is vertically threadedly connected to the oiling box 7, and the lower end of the lead screw 73 is rotatably connected to the lower guide wheel 72.

[0048] like Figure 7 As shown, the outlet position of the oil coating box 7 is horizontally connected to a coating tube 74 for the cable to pass through. The inner wall of the coating tube 74 is provided with a pair of spirally arranged brushes 75. The brushes 75 are arranged in a step shape and respectively contact the inner and outer metal strips.

[0049] After the cable armoring is complete, the lead screw 73 is first rotated, causing the pair of lower guide wheels 72 to move upward and position above the upper guide wheels 71. The cable is then passed through the oiling tank 7 and over the pair of upper guide wheels 71. The lead screw 73 is then reversed, causing the pair of lower guide wheels 72 to move downward, bending the cable and forming a U-shape within the oiling tank 7, where it is immersed in lubricating oil. The cable is then passed through the brushing tube 74, where the stepped brushes 75 contact the inner and outer metal strips.

[0050] When the cable passes through the oil coating box 7, it can be automatically dipped in lubricating oil. As the cable moves, the brushing tube 74 is controlled to rotate. At this time, the brush 75 in the oil coating tube evenly coats the grease on the inner and outer metal strips, and ensures the uniform coating of the coating, completing the uniform application of the lubricating oil.

[0051] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
