Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of tube stranding technology, and more specifically, to a tube stranding machine for wire and cable processing with good heat dissipation. Background Technology
[0002] In the process of wire and cable processing, tube stranding machines are often used to process wires and cables. The tube stranding machine mainly consists of a stranding forming part, a control system and a motor drive part. Its working principle is based on the physical characteristics of stranded wire. By repeatedly rotating and twisting multiple wires along the rotation axis, the wires are finally twisted and formed. In the existing technology, tube stranding machines easily generate a lot of heat due to the high-speed stranding of wires. If the heat dissipation is not good, it will affect the life of the equipment and the quality of the cable. In particular, during the high-speed rotation of the main shaft of the tube stranding machine, there is continuous friction between the main shaft and the bearing. If the bearing is not sufficiently lubricated, the coefficient of friction will increase significantly, resulting in a sharp increase in heat. If it is operated for a long time, it may cause the bearing to overheat and be damaged, and the heat dissipation effect is not good. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a wire and cable processing tube stranding machine with good heat dissipation effect, which solves the technical problem in the prior art that the continuous friction between the spindle and the bearing leads to a sharp increase in heat, which may cause the bearing to overheat and be damaged if it is operated for a long time, resulting in poor heat dissipation effect.
[0004] According to one aspect, at least one embodiment of this disclosure provides a tube stranding machine for wire and cable processing with good heat dissipation, including a tube stranding machine body. The tube stranding machine body includes a base, and a mounting seat is fixedly disposed on the base. A bearing is disposed in the mounting seat, and the bearing is coaxially fixedly engaged with a main shaft. A slot is formed on the mounting seat. The machine also includes an oil tank, a lubrication mechanism, a return flow assembly, and a cooling mechanism. The oil tank is disposed on the base, the lubrication mechanism is disposed on the base for spraying lubricating oil onto the bearing, the return flow assembly is disposed on the mounting seat for collecting the lubricating oil and returning it to the oil tank, and the cooling mechanism is disposed on the base for reducing the temperature of the bearing.
[0005] Preferably, the lubrication mechanism includes a first water pump, a spray pipe, and a spray head. The first water pump is mounted on the base, the input end of the first water pump is connected to one end of the oil storage tank, one end of the spray pipe is connected to the output end of the first water pump, and one end of the spray head is connected to the other end of the spray pipe.
[0006] Furthermore, the reflux assembly includes an oil inlet pipe, a collection hopper, and an opening and closing element. One end of the oil inlet pipe is connected to the top of the oil storage tank, one end of the collection hopper is connected to the other end of the oil inlet pipe, and the opening and closing element is disposed on the oil inlet pipe to control the flow of lubricating oil.
[0007] Furthermore, the opening and closing component includes a baffle and an electric cylinder. A sliding groove is provided on the oil inlet pipe. The baffle slides in conjunction with the inner wall of the sliding groove. The electric cylinder is installed on the inner side wall of the empty groove. The output end of the electric cylinder is fixedly connected to one end of the baffle.
[0008] As a further embodiment of this application, the cooling mechanism includes a coolant tank, a second water pump, an outlet pipe, a spiral pipe, a return pipe, and a water storage tank. The coolant tank is mounted on the base, the second water pump is mounted on the base, the input end of the second water pump is connected to the coolant tank, one end of the outlet pipe is connected to the output end of the second water pump, the spiral pipe is disposed within the mounting base and sleeved on the outside of the bearing, one end of the spiral pipe is connected to the other end of the outlet pipe, one end of the return pipe is connected to the other end of the spiral pipe, and the water storage tank is mounted on the base, with its top end connected to the other end of the return pipe.
[0009] As a further embodiment of this application, in order to fix the spray pipe and place the other end of the spray pipe on one side of the bearing, the spray head can be directed toward the bearing to spray lubricating oil. The mounting base is provided with a through groove that mates with the spray pipe, the middle part of the spray pipe is disposed in the through groove, and the spray head is inclined and directed toward the bearing.
[0010] Based on the aforementioned scheme, in order to quickly dissipate the heat generated by the bearing and to cool it down in conjunction with the cooling mechanism, a heat-conducting layer is provided on the bearing, and a cooling cavity that cooperates with the spiral tube is provided in the mounting base. The cooling cavity is an annular cavity, and multiple through holes are provided on the inner wall of the cooling cavity.
[0011] Furthermore, in order to increase the sealing between the baffle and the inner wall of the oil inlet pipe, a sealing sleeve is fitted on the baffle.
[0012] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, through the cooperation of the oil tank, lubrication mechanism and return assembly, due to the long-term operation of the bearing and spindle, the internal friction coefficient of the bearing increases and a large amount of heat is generated. By starting the first water pump, the lubricating oil is drawn out and sprayed towards the bearing through the spray head. There may be too much lubricating oil sprayed on the bearing, and the lubricating oil flowing out of the bearing will slide down the outer wall of the mounting base into the collection hopper and be on the baffle. Due to the high temperature of the bearing, the lubricating oil may heat up. After the lubricating oil cools down, the electric cylinder is started to "release" the blockage of the lubricating oil, so that the lubricating oil flows back into the oil tank for long-term use. This reduces the friction coefficient of the bearing and indirectly reduces the heat generation of the bearing. 2. In this disclosure, a cooling mechanism is provided. The second water pump is started to draw coolant from the coolant tank and transfer it to the spiral tube through the outlet pipe. The coolant flows in the spiral tube and enters the water storage tank through the return pipe. The coolant cools the mounting base, so that the temperature in the cooling chamber is conducted to the heat-conducting layer through multiple through holes. The heat generated by the bearing is transferred to the heat-conducting layer, and the low temperature in the cooling chamber cools the heat-conducting layer. This reduces the temperature of the bearing and avoids damage caused by excessive bearing temperature. Attached Figure Description

[0022] like Figures 1-6 As shown, it illustrates a wire and cable processing tube stranding machine with good heat dissipation in one embodiment of the present disclosure, including a tube stranding machine body 1, a base 2, a mounting seat 3 fixedly disposed on the base 2, a mounting hole opened in the mounting seat 3, a bearing 4 disposed in the mounting seat 3, the outer side wall of the bearing 4 being fixedly connected to the inner wall of the mounting hole, the bearing 4 being coaxially fixedly engaged with the main shaft 27, a drive mechanism 26 disposed on the base 2, the drive mechanism 26 being used to drive the main shaft 27 to rotate, a slot 5 opened on the mounting seat 3, and also includes an oil tank 6, a lubrication mechanism, a return flow assembly and a cooling mechanism; like Figures 2-4 As shown, the oil storage tank 6 is mounted on the base 2, and the lubrication mechanism is mounted on the base 2 for spraying lubricating oil onto the bearing 4. The lubrication mechanism includes a first water pump 7, a spray pipe 8, and a spray head 9. The first water pump 7 is mounted on the base 2, and the input end of the first water pump 7 is connected to one end of the oil storage tank 6. One end of the spray pipe 8 is connected to the output end of the first water pump 7. The input end of the first water pump 7 is connected to the oil storage tank 6 through a pipe. One end of the spray head 9 is connected to the other end of the spray pipe 8. In order to fix the spray pipe 8 and make the other end of the spray pipe 8 on one side of the bearing 4, the spray head 9 can spray lubricating oil toward the bearing 4. A through groove 21 that cooperates with the spray pipe 8 is opened in the mounting base 3. The middle part of the spray pipe 8 is set in the through groove 21. The spray head 9 is tilted and faces the bearing 4. By starting the first water pump 7, the first water pump 7 works to draw out the lubricating oil in the oil storage tank 6. The lubricating oil is transferred to the spray head 9 through the spray pipe 8 and sprayed toward the bearing 4. like Figure 4As shown, the return assembly is mounted on the mounting base 3 to collect lubricating oil and return it to the oil reservoir 6. The return assembly includes an oil inlet pipe 10, a collection hopper 11, and an opening and closing component. One end of the oil inlet pipe 10 is connected to the top of the oil reservoir 6, and one end of the collection hopper 11 is connected to the other end of the oil inlet pipe 10. The width of one end of the collection hopper 11 is greater than the width of the mounting base 3. The opening and closing component is mounted on the oil inlet pipe 10 to control the flow of lubricating oil. The opening and closing component includes a baffle 12 and an electric cylinder 14. A groove 13 is provided on the oil inlet pipe 10, and the baffle 12 slides in cooperation with the inner wall of the groove 13. The electric cylinder 14 is mounted on the inner wall of the empty groove 5. The output end of the electric cylinder 14 is fixedly connected to one end of the baffle 12. In order to increase the sealing between the baffle 12 and the inner wall of the oil inlet pipe 10, a sealing sleeve 25 is provided on the baffle 12. The lubricating oil sprayed on the bearing 4 may be too much, and the lubricating oil flowing out of the bearing 4 will slide down the outer wall of the mounting seat 3 into the collection hopper 11 and be above the baffle 12. Due to the high temperature of the bearing 4, the lubricating oil may heat up. After the lubricating oil cools down, the electric cylinder 14 is started. The output end of the electric cylinder 14 drives the baffle 12 to move, "releasing" the blockage of the lubricating oil, so that the lubricating oil flows back into the oil storage tank 6. like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a cooling mechanism is mounted on the base 2 to reduce the temperature of the bearing 4. The cooling mechanism includes a coolant tank 15, a second water pump 16, an outlet pipe 17, a spiral tube 18, a return pipe 19, and a water storage tank 20. The coolant tank 15 is mounted on the base 2 and contains coolant. The second water pump 16 is mounted on the base 2, with its input end connected to the coolant tank 15. One end of the outlet pipe 17 is connected to the output end of the second water pump 16. The spiral tube 18 is mounted inside the mounting base 3 and sleeved on the outside of the bearing 4. One end of the spiral tube 18 is connected to the other end of the outlet pipe 17. To quickly dissipate the heat generated by the bearing 4 and to cooperate with the cooling mechanism for cooling, a heat-conducting layer 22 is fitted onto the bearing 4. A cooling cavity 23, which mates with the spiral tube 18, is provided inside the mounting base 3. The cooling cavity 23 is an annular cavity. The cross-sectional area of cavity 23 is larger than that of mounting hole. Multiple through holes 24 are provided on the inner wall of cooling cavity 23. One end of return pipe 19 is connected to the other end of spiral pipe 18. Water tank 20 is set on base 2. The top of water tank 20 is connected to the other end of return pipe 19. By starting the second water pump 16, the second water pump 16 draws coolant from coolant tank 15 and transfers it to spiral pipe 18 through outlet pipe 17. Coolant flows in spiral pipe 18 and enters water tank 20 through return pipe 19. Coolant cools mounting base 3, especially cooling cavity 23. The temperature in cooling cavity 23 is reduced, so that the temperature in cooling cavity 23 is conducted to heat conduction layer 22 through multiple through holes 24. The heat generated by bearing 4 is transferred to heat conduction layer 22, and the low temperature in cooling cavity 23 cools heat conduction layer 22, thus reducing the temperature of bearing 4. Working principle: When this wire and cable processing pipe stranding machine with good heat dissipation is working, due to the long-term operation of the bearing 4 and the main shaft 27, the internal friction coefficient of the bearing 4 increases and a large amount of heat is generated. By starting the first water pump 7, the first water pump 7 works to draw out the lubricating oil in the oil storage tank 6. The lubricating oil is transferred to the spray head 9 through the spray pipe 8 and sprayed towards the bearing 4. There may be too much lubricating oil sprayed on the bearing 4, and the lubricating oil flowing out of the bearing 4 will slide down the outer wall of the mounting base 3 into the collection hopper 11 and be above the baffle 12. Due to the high temperature of the bearing 4, the lubricating oil may heat up. After the lubricating oil cools down, the electric cylinder 14 is started. The output end of the electric cylinder 14 drives the baffle 12 to move, "releasing" the blockage of the lubricating oil, so that the lubricating oil flows back into the oil storage tank 6. This reduces the friction coefficient of the bearing 4 and indirectly reduces the heat generated by the bearing 4. By starting the second water pump 16, the second water pump 16 draws coolant from the coolant tank 15 and transfers it to the spiral tube 18 through the outlet pipe 17. The coolant flows in the spiral tube 18 and enters the water storage tank 20 through the return pipe 19. The coolant cools the mounting base 3, especially the temperature in the cooling chamber 23. This allows the temperature in the cooling chamber 23 to be conducted to the heat-conducting layer 22 through multiple through holes 24. The heat generated by the bearing 4 is transferred to the heat-conducting layer 22, while the low temperature in the cooling chamber 23 cools the heat-conducting layer 22, thus reducing the temperature of the bearing 4.
