Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a wire drawing machine for high-power transmission cables. Background Art

[0002] Transmission cable is a cable used to transmit electrical energy, signals or data. The wire drawing process of transmission cable is a key step in manufacturing cable conductors. The wire drawing process gradually draws large diameter metal wires through a series of dies into conductors of the required diameter. The transmission cable wire drawing machine is a device used to gradually draw large diameter metal wires into conductors of the required diameter. When drawing the cable, the cable needs to be lubricated. At present, the cable is immersed in oil. However, if the cable is directly immersed in oil, the oil is easy to adhere to the cable, and the oil on the cable is easy to drip at will, thereby polluting the production environment, and causing waste of oil, increasing production costs. Utility Model Content

[0003] The utility model provides a wire drawing machine for high-power transmission cables, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A wire drawing machine for high-power transmission cables, comprising a vertical plate, a wire drawing die, an oil storage box and a bottom plate, wherein a first support plate, a wire drawing die and a third support plate are provided on the bottom plate, a guide roller is mounted on the bottom plate via the support of the first support plate, a wiping roller and a coating roller are mounted on the bottom plate via the support of the second support plate, and an oil storage box is provided on the second support plate below the coating roller, an extrusion roller is mounted on the bottom plate via the support of the third support plate, an vertical plate is provided on one end of the bottom plate close to the extrusion roller, a wire drawing die is inlaid on the vertical plate, and an extrusion hole is provided on the wire drawing die.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a fixing hole is provided on the vertical plate, a bolt is installed in the fixing hole, and the vertical plate and the wire drawing die are connected and fixed by bolts.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] The fixing holes and bolt connection make the installation and removal between the vertical plate and the drawing die more convenient and quick. You only need to tighten or loosen the bolts to easily complete the installation and replacement of the vertical plate and the drawing die, saving operation time and labor costs.

[0010] Furthermore, the extrusion roller is provided with shaping grooves, and the positions and numbers of the shaping grooves correspond one to one with the extrusion holes.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The shaping grooves on the extrusion roller correspond to the extrusion holes one by one, ensuring the shape consistency of the metal wire during the extrusion process. Each extrusion hole corresponds to a shaping groove, so that the shape of the metal wire can be accurately controlled during the extrusion process, ensuring the consistency of the geometric shape and size of the product. Through the one-to-one correspondence design between the extrusion holes and the shaping grooves, multiple metal wires can be shaped at one time, improving production efficiency. When the metal wire passes through the extrusion roller, it can be shaped into multiple products of the same shape at the same time, reducing the process and time in the production process and improving production efficiency.

[0013] Furthermore, the guide roller is provided with guide grooves, and the positions and numbers of the guide grooves correspond to the shaping grooves one by one.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The guide groove on the guide roller can effectively guide the metal wire through the squeeze roller and ensure that the position and direction of the metal wire are consistent with the shaping groove on the squeeze roller. In this way, the metal wire can be accurately shaped when passing through the squeeze roller, thereby ensuring the consistency of the shape and size of the product. Since the position and number of the guide groove and the shaping groove correspond to each other, there is no need to frequently adjust and calibrate the position and angle of the guide roller, reducing the maintenance cost and operation difficulty of the equipment.

[0016] Furthermore, an oil spreading roller is provided in the oil storage box, and the coating roller is in rolling contact with the wiping roller and the oil spreading roller respectively. The oil spreading roller spreads the oil in the oil storage box on the coating roller, and evenly spreads the oil on the treated metal wire through the coating roller, and absorbs excess oil on the metal wire through the wiping roller, so that the excess oil can flow back to the oil storage box.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The oil in the oil storage box is evenly applied to the coating roller through the oil spreading roller, and then the oil is evenly applied to the treated metal wire through the coating roller. This ensures that the oil lubrication is evenly distributed on the surface of the metal wire, avoiding production quality problems caused by insufficient or excessive lubrication. The design of the wiping roller helps to absorb excess oil on the surface of the metal wire and ensure that the amount of lubricating oil is just right. This not only helps to avoid waste caused by excessive oil, but also reduces the possibility of oil residue on the surface of the metal wire and improves the appearance quality of the product. After the excess oil is absorbed by the wiping roller, it is convenient for the excess oil to flow back to the oil storage box. This design helps to achieve the recycling of oil, reduce oil waste, reduce production costs, and is more environmentally friendly.

[0019] The beneficial effects of the utility model are:

[0020] The lubrication system composed of the coating roller and the oiling roller can ensure that the surface of the metal wire is smoothly and evenly coated with oil, which is of great significance for reducing the friction between the metal wire and the die, improving the wire drawing efficiency, reducing losses and ensuring product quality. And the excess oil is absorbed by the wiping roller and returned to the oil storage box, realizing the recycling of oil, reducing oil waste, reducing production costs, and being more environmentally friendly.

[0021] The shaping grooves on the extrusion roller can press the wire into the desired shape, ensuring the accurate size and shape of the conductor. This precise shaping process and the coordination between the various components make the size, shape and quality of the product more consistent, and improve the reliability and stability of the product. The extrusion hole can shape the wire into the desired cross-sectional shape by extrusion. When the wire passes through the extrusion hole, the wire will be subjected to greater pressure, causing the wire to undergo plastic deformation. Depending on the shape and size of the extrusion hole, the wire will obtain a corresponding cross-sectional shape, such as round, square or other specific shapes. The extrusion hole will also have a certain improvement effect on the surface of the wire, because the wire will be subjected to a certain degree of surface extrusion and plastic flow during the extrusion process, which helps to remove surface defects and oxides and improve the surface quality of the wire.

The bottom plate 15 is provided with a first support plate 11, a wire drawing die 3 and a third support plate 14. A guide roller 10 is supported and installed on the bottom plate 15 through the first support plate 11. The guide roller 10 is provided with guide grooves 9. The positions and numbers of the guide grooves 9 and the shaping grooves 5 correspond one to one. The guide grooves 9 on the guide roller 10 can effectively guide the metal wire to pass through the extrusion roller 6 and ensure that the position and direction of the metal wire are consistent with the shaping grooves 5 on the extrusion roller 6. In this way, the metal wire can be accurately shaped when passing through the extrusion roller 6, thereby ensuring the consistency of the shape and size of the product. Since the positions and numbers of the guide grooves 9 and the shaping grooves 5 correspond to each other, there is no need to frequently adjust and calibrate the positions and angles of the guide rollers 10, thereby reducing the maintenance cost and operation difficulty of the equipment. The wiping roller 8 and the coating roller 7 are supported and installed on the bottom plate 15 through the second support plate 13, and an oil storage box 12 is provided on the second support plate 13 below the coating roller 7. An oil distribution roller 16 is provided in the oil storage box 12, and the coating roller 7 is in rolling contact with the wiping roller 8 and the oil distribution roller 16 respectively. The oil distribution roller 16 applies the oil in the oil storage box 12 to the coating roller 7, and evenly applies the oil to the treated metal wire through the coating roller 7, and absorbs excess oil on the metal wire through the wiping roller 8, so that the excess oil can flow back to the oil storage box 12, and the oil in the oil storage box 12 is evenly applied to the coating roller 7 through the oil distribution roller 16, and then evenly applies the oil to the treated metal wire through the coating roller 7. This ensures that the oil lubrication is evenly distributed on the surface of the metal wire, avoiding production quality problems caused by insufficient or excessive lubrication. The design of the wiping roller 8 helps to absorb excess oil on the surface of the metal wire and ensure that the amount of lubricating oil is just right. This not only helps to avoid waste caused by excessive oil, but also reduces the possibility of oil residue on the surface of the metal wire and improves the appearance quality of the product. After the excess oil is absorbed by the wiping roller 8, it is convenient for the excess oil to flow back into the oil storage box 12. This design helps to achieve the recycling of oil, reduce the waste of oil, reduce production costs, and is more environmentally friendly. The bottom plate 15 is supported and installed with an extrusion roller 6 through a third support plate 14.

Each extrusion hole 4 corresponds to a shaping groove 5, so that the metal wire can be accurately controlled in shape during the extrusion process, ensuring the consistency of the geometric shape and size of the product. Through the one-to-one correspondence design between the extrusion holes 4 and the shaping grooves 5, it is possible to shape a plurality of metal wires at one time, thereby improving production efficiency.When the metal wire passes through the extrusion roller 6, it can be molded into multiple products of the same shape at the same time, which reduces the process and time in the production process and improves production efficiency.

And the excess oil is absorbed by the wiping roller 8 and returned to the oil storage box 12, so that the oil is recycled, the waste of oil is reduced, the production cost is reduced, and it is more environmentally friendly.

The extrusion hole 4 can shape the metal wire into the desired cross-sectional shape by extrusion. When the metal wire passes through the extrusion hole 4, the metal wire will be subjected to a large pressure, so that the metal wire will undergo plastic deformation. According to the shape and size of the extrusion hole 4, the metal wire will obtain a corresponding cross-sectional shape, such as round, square or other specific shapes. And the extrusion hole 4 will also have a certain improvement effect on the surface of the metal wire, because the metal wire will be subjected to a certain degree of surface extrusion and plastic flow during the extrusion process, which helps to remove surface defects and oxides and improve the surface quality of the metal wire.
