Detailed Implementation

[0030] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1As shown, this embodiment discloses a wire stranding device with a lubrication system, including a fixed shaft 1. One end of the fixed shaft 1 is fixedly connected to the base 2 via a frame. A stranding mechanism 3 is rotatably connected to the fixed shaft 1. One side of the stranding mechanism 3 is connected to a drive mechanism 4, and a pressing die 5 is provided on the other side of the stranding mechanism 3. A take-up device 7 is provided on the side of the pressing die 5 away from the stranding mechanism 3. A detachable protective cover 6 is provided between the stranding mechanism 3 and the pressing die 5. The protective cover 6 is mounted on the base via a frame. A drainage groove 6-1 is provided inside the protective cover 6, and a collection box 8 is provided below the protective cover 6. The wire released from the stranding mechanism 3 is shaped and sized by the pressing die 5, and finally taken up by the take-up device 7. The pressing die 5 is a prior art and will not be described in detail here.

[0032] An oil nozzle 9 is provided at one end of the fixed shaft 1, and the oil nozzle 9 is located inside the protective cover 6. The oil nozzle 9 is connected to the oil pump 11 through an oil pipe 10, which is also located inside the fixed shaft 1. An oil storage tank 12 is provided below the oil pump 11, and the oil pump 11 is connected to the oil storage tank 12. In this embodiment, the oil nozzle 9 is an atomizing nozzle, and multiple oil nozzles 9 are provided in a ring arrangement. When the twisting mechanism 3 twists the steel wire, oil is supplied to the oil nozzle 9 through the oil pump 11, and the oil nozzle 9 sprays oil mist onto the steel wire. The atomized oil mist can adhere more evenly.

[0033] like Figure 2 As shown, the protective cover 6 has several annular guide grooves 6-2 on its cylindrical wall, and a guide groove 6-1 is located at the lowest point of the annular guide grooves 6-2 and communicates with them. The collection box 8 has an oil inlet 8-1 located at the lowest point of the guide groove 6-1. The oil mist sprayed from the nozzle 9 is contained within the protective cover 6. Excess oil mist falling onto the cylindrical wall of the protective cover 6 flows through the annular guide grooves 6-2 into the guide groove 6-1, and then through the oil inlet 8-1 into the collection box 8 for unified recycling. The design of the protective cover 6 avoids the problem of lubricating oil splashing during twisting and solves the problem of lubricating oil waste through the collection box 8. The protective cover 6 is a detachable structure that can be disassembled into two halves, which are connected to the outside of the nozzle 9 and the steel wire, facilitating subsequent cleaning of the protective cover 6.

[0034] like Figures 3 to 5As shown, the twisting mechanism 3 includes a sleeve 3-1, which is sleeved on the fixed shaft 1 and rotatably connected to the fixed shaft 1 via bearings. A pay-off reel 3-2 is fixedly connected to the sleeve 3-1. A first pulley 3-3 is provided on the side of the pay-off reel 3-2 facing the drive mechanism 4, and the first pulley 3-3 is connected to the drive mechanism 4 via a synchronous belt. The pay-off reel 3-2 includes two disc bodies 3-2-1, with a wire outlet hole provided on the disc body 3-2-1 facing the fuel injector 9. A pay-off roller 3-2-2 is provided between the two disc bodies 3-2-1. The pay-off roller 3-2-2 is a cradle frame with a tensioning function. Cradle frames with tensioning functions are existing technology and will not be described in detail here. A wire pressing disc 3-4 is fixedly connected to the end of the sleeve 3-1 away from the drive mechanism 4, and the wire pressing disc 3-4 is located inside the protective cover 6. Multiple sets of winding wheels 3-4-1 arranged in a ring are provided on the wire pressing disc 3-4, with three winding wheels in each set. A guide disc 3-5 is provided between the wire pressing disc 3-4 and the wire feeding disc 3-2. The guide disc 3-5 is fixedly mounted on the sleeve 3-1, and has corresponding wire outlet holes at positions corresponding to the wire outlet holes of the disc body 3-2-1. The positions of the wire outlet holes of each set of winding wheels 3-4-1, the guide disc 3-5, and the disc body 3-2-1 are aligned. The steel wire is released from the wire feeding roller 3-2-2, passes through the disc body 3-2-1, the guide disc 3-5, and the three winding wheels 3-4-1, and is finally compressed in the wire pressing die 5.

[0035] In this embodiment, a reinforcing frame 3-2-3 is also provided between the disc body 3-2-1 and the guide disc 3-5 to provide auxiliary support.

[0036] In this embodiment, the pay-off reel 3-2, the guide plate 3-5, and the fixing frame 3-6 are rotatably connected. The fixing frame 3-6 provides auxiliary support for the pay-off reel 3-2 and the guide plate 3-5.

[0037] like Figure 4 As shown, the drive mechanism 4 includes a first motor 4-1 mounted on the base 2. The output end of the first motor 4-1 is provided with a second pulley 4-2. The second pulley 4-2 is connected to the first pulley 3-3 via a synchronous belt. When the first motor 4-1 rotates, it drives the first pulley 3-3, the wire feeding reel 3-2, the sleeve 3-1, the guide plate 3-5, and the pressure plate 3-4 to rotate as a whole by means of the synchronous belt, thereby realizing the twisting of the steel wire.

[0038] like Figure 6As shown, the fixing frame 3-6 includes a fixing frame body 3-6-1, which is mounted on the base 2. Three fixing plates 3-6-2 are mounted on the fixing frame body 3-6-1. Each fixing plate 3-6-2 has a circular hole, and a slide rail 3-6-3 is mounted on the inner wall of the circular hole. Slide grooves are provided on the circumferential walls of the two discs 3-2-1 and the guide disc 3-5. The two discs 3-2-1 and the guide disc 3-5 are rotatably connected to the fixing frame body 3-6-1 via the slide rails 3-6-3. Therefore, the fixing frame 3-6 provides support for the rotation of the wire feeding disc 3-2 and the guide disc 3-5.

[0039] like Figure 7 As shown, the take-up device 7 includes a take-up platform 7-1. On the side of the take-up platform 7-1 facing the wire pressing die 5, there are two horizontal pressing rollers 7-2 and two vertical pressing rollers 7-3. The two horizontal pressing rollers 7-2 are placed side by side in the horizontal direction, and the two vertical pressing rollers 7-3 are placed one above the other in the vertical direction. The stranded wire rope passes through the two horizontal pressing rollers 7-2 and the two vertical pressing rollers 7-3 in sequence. The two horizontal pressing rollers 7-2 press tightly on both sides of the wire rope in the horizontal direction for further horizontal pressing, and the two vertical pressing rollers 7-3 press tightly on both sides of the wire rope in the vertical direction for further vertical pressing.

[0040] A take-up wheel 7-4 is provided on the side of the take-up table 7-1 away from the wire pressing die 5. The take-up wheel 7-4 is connected to the second motor 7-5 via a synchronous belt. This synchronous belt connection method is the same as the synchronous belt connection method between the first motor 4-1 and the wire feeding reel 3-2, and will not be described in detail here.

[0041] In this embodiment, two tension rollers 7-6 are provided between the take-up reel 7-4 and the vertical pressing roller 7-3. Both tension rollers 7-6 are mounted on the take-up table 7-1 via a frame. The two tension rollers 7-6 are arranged in a staggered pattern, one in front of the other and one at a different height, with the tension roller 7-6 closer to the take-up reel 7-4 positioned lower. The wire rope passes over the tension roller 7-6 on the side furthest from the take-up reel 7-4 and under the tension roller 7-6 on the side closer to the take-up reel 7-4, finally winding itself onto the take-up reel 7-4. The height of both tension rollers 7-6 is adjustable to facilitate tensioning of the wire rope.

[0042] The working process of this utility model is as follows:

[0043] First, the steel wire is released from the pay-off roller 3-2-2, passes through the reel 3-2-1, the guide plate 3-5, and three winding wheels 3-4-1, and is finally compressed in the pressing die 5. The first motor 4-1 is started, which drives the first pulley 3-3, pay-off reel 3-2, sleeve 3-1, guide plate 3-5, and pressing reel 3-4 to rotate as a whole. The steel wire is twisted under the compression of the pressing die 5 and the rotation of the twisting mechanism 3. At the same time, the oil pump 11 is started, and the oil nozzle 9 sprays oil mist onto the steel wire. The oil mist sprayed by the oil nozzle 9 is covered in the protective cover 6. When the excess oil mist falls on the cylinder wall of the protective cover 6, it flows through the annular guide groove 6-2 into the diversion groove 6-1, and then through the oil inlet 8-1 into the collection box 8 for unified recycling and treatment.

[0044] After being twisted, the wire rope passes through two horizontal pressing rollers 7-2, two vertical pressing rollers 7-3, and two tension rollers 7-6 in sequence. After being pressed horizontally again by the two horizontal pressing rollers 7-2 and vertically by the two vertical pressing rollers 7-3, it is then tightened by the two tension rollers 7-6 and finally wound onto the take-up reel 7-4. The take-up reel 7-4 is driven by the second motor 7-5 to achieve the winding action.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
