Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of lubricating devices of armoring machines, and in particular, to a novel lubricating device of a cable armoring machine. BACKGROUND

[0002] In the cable armoring process, the mold of the armoring machine is a key component for guiding the covering of the cable armor layer (such as steel tape or steel wire), and the lubricating effect directly affects the surface quality of the cable and the service life of the equipment. However, the traditional lubricating device of the armoring machine generally has problems such as uneven lubrication and poor real-time performance, which leads to serious damage to the mold due to excessive friction when the cable passes at high speed, and becomes a technical bottleneck restricting production efficiency and cost control.

[0003] Existing armoring machines mostly use manual greasing or intermittent oil spraying, which cannot dynamically adjust the lubricating amount according to parameters such as cable diameter and armoring speed. For example, when the cable passes through the mold at a speed of 200-500 r / min, the traditional device often has local dry friction due to long oil supply intervals (usually manual oiling 1-2 times per hour), which causes scratches on the surface of the inner hole of the mold and aggravates the wear, and the average service life is shortened to about 300 hours. At the same time, uneven lubrication can cause scratches on the surface of the cable armor layer, affecting the insulation performance, and even causing short circuit risk in later use.

[0004] Although some equipment is equipped with an automatic lubricating pump, it uses a fixed flow oil supply mode, and when the mold gap becomes larger due to wear, it still supplies oil according to the initial parameters, which not only wastes lubricating oil, but also causes metal debris to be adsorbed and form abrasive particles due to the accumulation of excess grease in the mold groove, further aggravating wear. According to statistics, under the traditional lubrication mode, the armoring machine mold needs to be replaced 2-3 times per week, and each replacement takes about 4 hours, which not only increases the operation and maintenance cost (the cost of a single mold is several thousand yuan), but also causes frequent shutdown of the production line, resulting in a loss of production capacity of more than 15%.

[0005] With the increasing demand for high-voltage cables and special cables, the armoring precision requirement is improved to ±0.1 mm, and the traditional lubricating device cannot meet the requirements of mold life extension and cable quality control. It is urgent to develop a new device with dynamic self-adaptive lubrication and wear monitoring function to solve the industry pain points such as short service life and frequent maintenance of the mold due to friction damage, and promote the development of cable armoring process towards high efficiency and intelligence.

[0036] A micro water pump 3 installed on the side surface of the lubricating storage tank 2 and a docking assembly 5 arranged between the fixed frame 1 and the lubricating storage tank 2;

[0037] An oil covering assembly 4 arranged at the bottom of the fixed frame 1;

[0038] The oil covering assembly 4 comprises a fitting wheel 4-1 rotatably connected to the side surface of the fixed frame 1, the surface of the fitting wheel 4-1 is provided with a covering layer 4-2, the bottom of the fixed frame 1 is provided with a base frame 4-3, a rectangular port 4-4 is opened on the surface of the fixed frame 1, the base frame 4-3 is located below the rectangular port 4-4, a transition box 4-5 is arranged in the base frame 4-3, a hose 4-6 is arranged on the side surface of the transition box 4-5, the output end of the micro water pump 3 is insertedly connected with the hose 4-6, a recess 4-7 is opened on the surface of the transition box 4-5, the recess 4-7 is filled with adsorbing cotton 4-8, a connecting wheel 4-9 is rotatably connected in the rectangular port 4-4, the connecting wheel 4-9 is in close contact with the surface of the adsorbing cotton 4-8 and the covering layer 4-2, a plurality of oil outlets 4-10 are opened in the recess 4-7, a drive motor 4-11 is arranged at the bottom of the base frame 4-3, a cam 4-12 is arranged at the output end of the drive motor 4-11, connecting rods 4-13 are arranged on both sides of the transition box 4-5, the connecting rods 4-13 are movably sleeved in the base frame 4-3, springs 4-14 are sleeved on both ends of the connecting rods 4-13, a pair of protrusions 4-15 are arranged at the bottom of the transition box 4-5, and the cam 4-12 is located between the protrusions 4-15.

[0039] In some examples, in order to achieve the lubricating effect of uniform oil covering on the surface of the cable, the oil covering assembly 4 is designed, which takes the fitting wheel 4-1 rotatably connected to the side surface of the fixed frame 1 as the core, the surface covering layer 4-2 adopts high-elasticity fiber material, which can closely contact the surface of the cable and carry lubricating oil, the transition box 4-5 is arranged in the base frame 4-3 at the bottom of the fixed frame 1, the adsorbing cotton 4-8 filled in the recess 4-7 in the box is communicated with the micro water pump 3 through the hose 4-6, the water pump delivers the lubricating oil in the lubricating storage tank 2 to the adsorbing cotton 4-8 to keep it in a wet state, the connecting wheel 4-9 in the rectangular port 4-4 is in close contact with the adsorbing cotton 4-8 and the covering layer 4-2 at the same time, when the cable pulls the connecting wheel 4-9 to rotate, the connecting wheel 4-9 rubs the adsorbing cotton 4-8 to absorb lubricating oil, and the lubricating oil is transmitted to the surface of the covering layer 4-2 through contact.

[0040] The driving motor 4-11 at the bottom of the chassis 4-3 drives the cam 4-12 to rotate periodically, and the cam 4-12 is located between the protrusions 4-15 at the bottom of the transition box 4-5. When rotating, the protrusions 4-15 are pressed to make the transition box 4-5 sway left and right along the connecting rod 4-13. The oil outlet hole 4-10 in the groove 4-7 avoids staying in one position to slow down and cause wear on the adsorbing cotton 4-8. The springs 4-14 at both ends of the connecting rod 4-13 provide a restoring force to ensure that the transition box 4-5 sways smoothly.

[0041] Through the oil storage and conduction of the adsorbing cotton 4-8, the contact oil transmission of the contact wheel 4-9, the surface smearing of the cover layer 4-2, and the vibration oil supplement of the cam 4-12, the oil covering assembly 4 realizes efficient transmission of lubricating oil from the storage tank to the surface of the cable, ensuring that the cable is continuously and uniformly lubricated during the cabling process.

[0043] In some examples, the docking assembly 5 is designed to realize quick assembly and disassembly and stable connection of the lubricating storage tank 2 and the fixed frame 1. The assembly takes the connecting plate 5-1 fixed at the bottom of the lubricating storage tank 2 as the installation carrier, and the T-shaped splicing grooves 5-2 at the side end face of the connecting plate 5-1 are accurately matched with the sliding protrusions on the outer side of the fixed frame 1, so that the fixed frame 1 can be vertically inserted into the splicing grooves 5-2 to form preliminary positioning. Bolt holes are opened at the corresponding positions of the connecting plate 5-1 and the fixed frame 1, and after the bolts are inserted and tightened, the two can be rigidly fixed to avoid shaking of the storage tank during equipment operation. When disassembling, the bolts are loosened, and the storage tank is lifted upward to complete the separation, which is convenient to operate.

[0044] This plug-in structure design not only ensures the stability of the storage tank after installation, but also facilitates periodic disassembly, cleaning or replacement, which adapts to the maintenance needs of the cabling and armor machine. Through the guiding positioning of the splicing grooves 5-2 and the fastening connection of the bolts, the docking assembly 5 realizes the quick assembly and disassembly function of the lubricating storage tank 2, providing convenience for the daily use and maintenance of the equipment.

[0045] For example, as shown in Figure 1 , the side surface of the lubricating storage tank 2 is provided with a battery pack 6 and a controller 7.

[0046] In some examples, the battery pack 6 and the controller 7 can cooperate to control the delivery amount of lubricating oil in the lubricating storage tank 2.
