Description

Technical Field

[0001] The invention relates to a profiled wire production device, in particular to a profiled wire conductor drawing and forming device and a production process thereof. Background Art

[0002] In recent years, the wire and cable industry has maintained a high growth rate and has occupied an important position in the industrial manufacturing industry. In 2019, the total output value of the wire and cable industry exceeded that of automobiles, becoming the largest industrial industry. Most of my country's power cable manufacturers use round compressed conductors. When twisting the conductors, the annealed copper monofilaments are re-compressed and hardened, and the lattice deformation is serious, the resistance increases, and the amount of copper material increases accordingly. Compared with traditional round compressed copper conductors, profiled wire conductors have certain advantages in terms of structural size, material consumption and production efficiency. China has issued and implemented the national standard GB / T 20141-2006 "profiled wire concentric stranded overhead conductor" [2], but profiled wire power cable conductors have not been promoted. Although profiled wire power cable conductor technology has been adopted in developed countries in Europe and the United States, it is not compatible with round compressed conductor equipment in China due to equipment constraints. The investment cost of special profiled wire equipment is too high, which has become a huge obstacle to the promotion of profiled wire. This article introduces the characteristics of the profiled wire conductor technology, and how to draw the profiled wire single wire through mold ratio without changing the equipment; and then use process methods to complete the application of profiled wire twisting on ordinary twisting equipment.

[0003] In the production process of wire conductors, wire drawing machines will inevitably be used.

[0004] The wire drawing machine is equipped with two wire drawing dies and wire drawing rollers. The two wire drawing dies are located on the front and rear sides of the wire drawing roller respectively. The wire body in the wire conductor to be processed must first pass through the first wire drawing die for pre-drawing treatment, and then be wound on the outer roller wall of the wire drawing roller for straightening treatment, and finally pass through the second wire drawing die for post-drawing treatment. The wire body after drawing and straightening treatment is transported to other workstations for subsequent processing of the wire conductor.

[0005] Although the wire drawing machine of the above structure can complete the basic drawing and straightening actions, the different numbers of wires wound on the wire drawing roller will have different effects on the straightening effect. Therefore, the number of wire windings on the wire drawing roller needs to be determined according to the wires of different specifications.

[0006] The wire body wound on the wire drawing roller will form two ends, one of which is located near the first wire drawing die, and the other is located near the second wire drawing die.

[0007] The wire needs to be laid flat and wound on the drawing roller. When the number of wire turns on the drawing roller is large, the distance between the wire conductor close to the first drawing die and the wire conductor close to the second drawing die becomes larger. At this time, the two fixed drawing dies will produce lateral pulling force on the wire wound on the drawing roller. The winding of the wire on the drawing roller is unstable, and the drawing die cannot stably receive the incoming and outgoing wires. Summary of the invention

[0008] In view of this, the first object of the present invention is to provide a wire conductor drawing and forming device, which can adjust the relative position of the drawing die according to actual needs and meet the wire drawing and forming needs of the wire body in wire conductors of different specifications.

[0019] Of course, the diameters of the first wire drawing roller and the second wire drawing roller may also be different, so that wire conductors of different models and different straightening requirements can be straightened.

[0030] Through the above technical solution, during normal use, for the first wire drawing roller, the elastic force of the first wire drawing spring acts on the first wire drawing extrusion end, and the first wire drawing extrusion end is wedge-matched with the end of the first wire drawing limit block, so that the first wire drawing limit block and the outer roller surface of the first wire drawing roller are limited, and then the first wire drawing retaining edge is fixed on the first wire drawing roller; for the second wire drawing roller, the elastic force of the second wire drawing spring acts on the second wire drawing extrusion end, and the second wire drawing extrusion end is wedge-matched with the end of the second wire drawing limit block, so that the second wire drawing limit block and the second wire drawing roller are fixed.

[0032] The elastic force of the second wire drawing spring acts on the second wire drawing extrusion end and causes the second wire drawing trigger end to protrude from the side wall of the second wire drawing rib;

[0034] Through the above technical scheme, when it is necessary to increase the overall length of the wire winding, the limiting effect of the second limiting member on the second wire drawing roller is released, and the second wire drawing roller approaches the position of the first wire drawing roller, the first wire drawing release end is abutted against the second wire drawing contact end, the first wire drawing limit block is no longer tightly pressed against the outer roller body of the first wire drawing roller, and the second wire drawing limit block is no longer tightly pressed against the outer roller body of the second wire drawing roller. At this time, the first wire drawing rib and the second wire drawing rib are always kept close to each other, so that the first wire drawing rib and the second wire drawing rib can be moved to one side together; in the above action, the automatic separation between the first wire drawing rib and the first wire drawing roller and the automatic separation between the second wire drawing rib and the second wire drawing roller are realized.

[0035] Preferably, a first magnetic attraction portion is provided on a side of the first drawing rib facing the second drawing rib, and a second magnetic attraction portion is provided on a side of the second drawing rib facing the first drawing rib, and the first magnetic attraction portion and the second magnetic attraction portion are magnetically attracted to each other.

The third magnetic attraction part is used to magnetically attract the second magnetic attraction part. The contact sensing part is electrically connected to the lifting drive part. When the contact sensing part contacts the second drawing rib, the lifting drive part drives the telescopic rod to move upward.

[0043] Through the above technical scheme, when the second wire drawing roller moves toward the first wire drawing roller, the first wire drawing roller will squeeze the first rod end of the trigger rod, and the trigger rod moves in the direction away from the first wire drawing roller. The second rod end of the trigger rod drives the telescopic rod through the transmission gear set, and the telescopic rod moves to the side of the second wire drawing rib. When the end of the telescopic rod close to the first wire drawing roller is close to the second wire drawing rib, the third magnetic attraction part is magnetically attracted to the second magnetic attraction part. At this time, the first magnetic attraction part, the second magnetic attraction part, and the third magnetic attraction part are magnetically attracted to each other, that is, the first wire drawing rib, the second wire drawing rib, and the telescopic rod are attached together. At the same time, after the contact sensing part contacts the second wire drawing rib, the lifting drive part drives the telescopic rod to move upward, and the telescopic rod is disengaged from the transmission gear set. Under the influence of the tension of the third wire drawing spring, the telescopic rod drives the first wire drawing rib and the second wire drawing rib to move simultaneously toward the side of the second wire drawing roller. At this time, the wire body can be wound and straightened using the outer roller surfaces of the first wire drawing roller and the second wire drawing roller.

[0044] Therefore, the above action fully utilizes the approaching action between the second wire drawing roller and the first wire drawing roller, so that the first wire drawing rib and the second wire drawing rib are automatically moved to one side of the second wire drawing roller, and the operation is convenient.

DETAILED DESCRIPTION

[0059] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0060] Embodiment 1:

[0061] The invention discloses a wire drawing and forming device for a shaped wire conductor, which is used for processing a wire body of the shaped wire conductor, and the wire body is generally a copper wire.

[0062] In addition to round wire twisting, conductors with single-wire twisting such as trapezoidal, fan-shaped, Z-shaped, and S-shaped can all be called shaped wire conductors.

[0063] At present, the main low-wind pressure conductors are trapezoidal, Z-shaped and arc-grooved. The typical types are as follows: Figure 6 The structures a, b, and c are shown.

[0064] It is worth noting that Figure 6 The c shown is a low-wind pressure conductor with an arc groove shape. Under the same conditions of impact force, impact angle, wind speed and wind direction, a golf ball with many small dimples on its surface will fly farther than a ball with a smooth surface. A sphere or cylinder with many small dimples on its surface will experience less wind resistance than a sphere or cylinder with a smooth surface, indicating that a sphere or cylinder with a certain "roughness" on its surface has a smaller wind resistance coefficient. Changing the shape of the outer surface of the conductor can reduce the reflow area and thus reduce the wind resistance coefficient.
