Description

Technical Field

[0001] This utility model relates to the field of power cable processing, specifically a wire stranding machine for power cable processing. Background Technology

[0002] Cables are commonly used devices for transmitting electrical energy or signals, and are generally composed of a single conductor, several conductors, or several groups of conductors. Because multiple conductors, after being twisted together, have advantages such as good flexibility, high reliability, high strength, and good stability, all multi-conductor cables currently use a stranding machine to twist the copper wires together to form a single conductor.

[0003] According to Chinese Patent No. CN220821204U, a stranding machine for power cable processing is disclosed. This utility model has the advantages of convenient observation through the observation window, which allows for timely adjustment by personnel. The support plate can limit the entry position of the wire, thereby preventing the wire from getting tangled together and breaking due to friction during the entry process, thus improving its practicality. The limiting tube limits the position of the cable, preventing the cable from deviating and being unable to enter the placement tube.

[0004] Regarding the aforementioned patent content, a method is used that involves setting up two gears and a wire winch, with one gear mounted on the wire winch. The two gears mesh and rotate to rotate the wire winch, thereby achieving the purpose of wire winch. However, after prolonged meshing and transmission, in order to prevent the gears from wearing out too quickly, lubricating oil needs to be applied to the gears for lubrication. However, manually applying lubricating oil to the gears takes a lot of time and is quite troublesome, thus reducing the lubrication efficiency of the gears. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a wire stranding machine for power cable processing to solve the technical problem of inconvenient rapid lubrication of gears.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire stranding machine for power cable processing, comprising a base plate, a wire stranding box mounted on the top of the base plate, a fixing plate fixed to one side of the inside of the wire stranding box, and a fixing ring mounted on the top of the fixing plate, an oil immersion assembly provided inside the wire stranding box, the oil immersion assembly comprising two guide rods mounted on the bottom of the fixing plate and a lead screw mounted on the lower inside of the wire stranding box via a bearing, a slide seat sleeved on the outer wall of the lead screw, a lifting plate sleeved between the two guide rods, and a push plate connected between the lifting plate and the slide seat via a rotating shaft, and an oil immersion box mounted on the top of the lifting plate, one end of the lead screw extending to the outside of the wire stranding box and connected to a rotating handle.

[0007] By adopting the above technical solution, when the slide moves, it will push the push plate to rotate, and the push plate can push the lifting plate to move, so that the lifting plate will drive the oil immersion tank to move upward.

[0008] Furthermore, two oil baffles are installed on the top of the oil immersion tank. The side walls of the oil baffles are smooth, and the oil baffles are inclined downward along the direction of the oil immersion tank.

[0009] By adopting the above technical solution, the oil baffle can block splashing lubricating oil and prevent the lubricating oil on the surface of the driven gear and the driving gear from splashing onto the inner wall of the winding box when they rotate.

[0010] Furthermore, the oil-immersion assembly also includes a limiting rod installed inside the wire-spinning box, the limiting rod passing through the slide block.

[0011] By adopting the above technical solution, the limiting rod can guide the slide, thereby improving the stability of the slide when it moves.

[0012] Furthermore, the inside of the fixed ring is connected to a wire spool via a bearing, the wire spool has multiple first wire inlet holes, and a driven gear is installed on the outer wall of the wire spool.

[0013] By adopting the above technical solution, when the driven gear rotates, it will drive the stranding disc to rotate, thereby performing stranding operations on multiple wires.

[0014] Furthermore, a motor is installed on the other side of the inside of the wire-winding box, and the output end of the motor is connected to a drive gear, which meshes with the driven gear.

[0015] By adopting the above technical solution, when the wire reel needs to rotate, the motor can be started. The operation of the motor can drive the drive gear to rotate, which in turn drives the driven gear to rotate.

[0016] Furthermore, a wire inlet plate is installed on one side of the wire twisting box, and multiple second wire inlet holes are opened in the wire inlet plate. Multiple connecting rods are also fixed on one side of the wire twisting box, and a support plate is installed at one end of the connecting rod. Multiple third wire inlet holes are opened on the support plate.

[0017] By adopting the above technical solution, the second and third wire inlets are designed so that the wires can be inserted into the wire twisting box, which facilitates subsequent wire twisting operations.

[0018] Furthermore, a wire outlet is provided on the other side of the wire box.

[0019] By adopting the above technical solution, the outlet is designed so that the cable can pass through the strand box.

[0020] Furthermore, a sealing door is installed on the outer surface of the wire twisting box via a hinge, and a glass plate is provided on the sealing door.

[0021] By adopting the above technical solution, the glass plate is installed so that staff can see the inside of the wire-winding box.

[0022] Furthermore, the lead screw is threadedly connected to the slide block.

[0023] By adopting the above technical solution, when the lead screw rotates, it will drive the slide to move, so as to adjust the position of the slide.

[0024] Furthermore, the oil immersion tank and the lifting plate are slidably connected to the guide rod, the diameter of the drive gear is smaller than the length of the oil immersion tank, and the drive gear is located directly above the oil immersion tank.

[0025] By adopting the above technical solution, when the oil immersion tank is moved upward, the bottom of the drive gear can be immersed into the inside of the oil immersion tank in order to lubricate the drive gear.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model features an oil immersion assembly. The oil immersion tank stores lubricating oil. When lubrication of the driving gear and driven gear is required, the operator can rotate the lead screw via a handle. The rotation of the lead screw will drive the slide to move. When the slide moves, it will push the push plate to rotate. The push plate will then push the lifting plate to move, causing the lifting plate to move the oil immersion tank upward. This allows the bottom of the driving gear to be immersed in the oil immersion tank for lubrication. Since the driving gear and driven gear are meshed, when the driving gear rotates, it will drive the driven gear to rotate, allowing the lubricating oil on the driving gear to be transferred to the teeth of the driven gear for lubrication. This method allows for quick lubrication of the driving gear and driven gear without the need for the operator to manually apply lubricating oil to the driving gear and driven gear, simplifying the operation steps and improving the lubrication efficiency of the driving gear and driven gear.

[0028] 2. This utility model is equipped with an oil baffle plate, which can block splashing lubricating oil and prevent the lubricating oil on the surface of the driven gear and the driving gear from splashing onto the inner wall of the wire winch box when they rotate. Because the oil baffle plate is tilted, the lubricating oil on the oil baffle plate can flow back into the oil immersion tank.

[0029] 3. This utility model provides a limiting rod to guide the slide block and prevent it from rotating, thereby improving the stability of the slide block during movement. The guide rod also guides the lifting plate and the oil immersion tank. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A wire stranding machine for processing power cables, such as Figures 1-6As shown, the device includes a base plate 1, a wire twisting box 2 mounted on top of the base plate 1, a fixing plate 4 fixed to one side of the inside of the wire twisting box 2, and a fixing ring 6 mounted on the top of the fixing plate 4. The top of the fixing ring 6 is connected to the wire twisting box 2 via a fixing rod. An oil-immersed assembly 9 is provided inside the wire twisting box 2. A wire twisting disc 7 is connected to the inside of the fixing ring 6 via a bearing. The wire twisting disc 7 has multiple first wire inlet holes 8. A driven gear 10 is mounted on the outer wall of the wire twisting disc 7. When the driven gear 10 rotates, it drives the wire twisting disc 7 to rotate, thereby twisting multiple strands of wire. A motor 15 is mounted on the other side of the inside of the wire twisting box 2. A drive gear 16 is connected to the output end of the motor 15. The drive gear 16 meshes with the driven gear 10. When it is necessary to rotate the wire twisting disc 7, the motor 15 can be started. The operation of the motor 15 can drive the drive gear 16 to rotate, thereby driving the driven gear 10 to rotate.

[0041] See Figure 1 , Figure 2 , Figure 3 and Figure 6 A wire inlet tray 5 is installed on one side of the wire twisting box 2. The wire inlet tray 5 has multiple second wire inlet holes 11. Multiple connecting rods 12 are also fixed on one side of the wire twisting box 2. A support plate 13 is installed at one end of the connecting rod 12. Multiple third wire inlet holes 14 are opened on the support plate 13. The second wire inlet holes 11 and the third wire inlet holes 14 are set so that the wire can be passed into the wire twisting box 2, which is convenient for subsequent wire twisting operations. A wire outlet 3 is opened on the other side of the wire twisting box 2. The wire outlet 3 is set so that the cable can pass through the wire twisting box 2. A sealing door 17 is installed on the outer surface of the wire twisting box 2 by a hinge. A glass plate 18 is set on the sealing door 17 so that the operator can see the internal situation of the wire twisting box 2. A control panel 19 is installed on the top of the wire twisting box 2. The control panel 19 is electrically connected to the motor 15.

[0042] Specifically, the oil immersion assembly 9 includes two guide rods 901 installed at the bottom of the fixed plate 4 and a lead screw 904 installed inside the lower part of the wire spool box 2 via bearings. A slide 907 is fitted onto the outer wall of the lead screw 904. A lifting plate 903 is fitted between the two guide rods 901, and a push plate 906 is connected to the lifting plate 903 and the slide 907 via a rotating shaft. An oil immersion tank 902 is installed on the top of the lifting plate 903. One end of the lead screw 904 extends to the outside of the wire spool box 2 and is connected to a handle 908. When the slide 907 moves, it pushes the push plate 906 to rotate, and the push plate 906 can... The lifting plate 903 is pushed to move, causing the lifting plate 903 to move the oil immersion tank 902 upward. The lead screw 904 is threadedly connected to the slide 907. When the lead screw 904 rotates, it will drive the slide 907 to move, so as to adjust the position of the slide 907. The oil immersion tank 902 and the lifting plate 903 are slidably connected to the guide rod 901. The diameter of the drive gear 16 is smaller than the length of the oil immersion tank 902. The drive gear 16 is located directly above the oil immersion tank 902, so that when the oil immersion tank 902 moves upward, the bottom of the drive gear 16 can be immersed into the interior of the oil immersion tank 902 for lubrication.

[0043] Example 2:

[0044] Based on the above embodiment 1, in order to prevent lubricating oil from splashing onto the inner wall of the wire winch box 2 when the driving gear 16 and the driven gear 10 rotate, the following structure will be provided.

[0045] Specifically, two oil baffles 909 are installed on the top of the oil immersion tank 902. The side walls of the oil baffles 909 are smooth and the oil baffles 909 are inclined downward along the direction of the oil immersion tank 902. The oil baffles 909 can block splashing lubricating oil and prevent the lubricating oil on the surface of the driven gear 10 and the driving gear 16 from splashing onto the inner wall of the wire winch box 2 when they rotate.

[0046] Example 3:

[0047] Based on the above embodiment 1, in order to improve the stability of the slide 907 when it moves, it needs to be guided, so the following structure will be set.

[0048] See Figures 2-5 The oil-immersion assembly 9 also includes a limiting rod 905 installed inside the wire-spinning box 2. The limiting rod 905 passes through the slide 907 and can guide the slide 907, thereby improving the stability of the slide 907 when it moves.

[0049] The working principle of this utility model is as follows: First, when using it, the operator can pass one end of the wire through the third inlet hole 14 on the support plate 13, then through the second inlet hole 11 on the inlet plate 5, and finally insert it into the first inlet hole 8 on the twisting plate 7. After the wire is positioned, the operator closes the sealing door 17 and starts the motor 15. The motor 15 can drive the drive gear 16 to rotate, which in turn drives the driven gear 10 to rotate. When the driven gear 10 rotates, it will drive the twisting plate 7 to rotate, thereby twisting the multiple wires. After the twisting is completed, the cable is passed out through the outlet 3.

[0050] Since the oil immersion tank 902 stores lubricating oil, when lubrication of the driving gear 16 and driven gear 10 is required, the operator can rotate the lead screw 904 through the handle 908. The rotation of the lead screw 904 will cause the slide 907 to move. The movement of the slide 907 will push the push plate 906 to rotate, which in turn will push the lifting plate 903 to move. This causes the lifting plate 903 to move the oil immersion tank 902 upwards, allowing the bottom of the driving gear 16 to be immersed in the oil immersion tank 902 for lubrication. At this time, the motor 15 is started, and the motor 15 drives the driving gear 16 to rotate slowly. When gear 6 rotates, it will drive the driven gear 10 to rotate, so that the lubricating oil on the driving gear 16 can be transmitted to the teeth of the driving gear 10 to lubricate the driving gear 10. After the driving gear 16 and the driven gear 10 are lubricated, the operator can rotate the lead screw 904 in the opposite direction to reset the slide 907 and move it. Then, the lifting plate 903 and the oil immersion tank 902 will move down, so that the bottom of the driving gear 16 will no longer be immersed in the oil immersion tank 902. The oil baffle 909 can block the splashing lubricating oil and prevent the lubricating oil on the surface of the driven gear 10 and the driving gear 16 from splashing onto the inner wall of the wire winch box 2 when they rotate.
