Description

A copper-clad aluminum wire tension device Technical Field

[0001] This invention relates to the field of wire drawing machine technology, specifically to a tension device for copper-clad aluminum wire. Background Technology

[0002] Copper-clad aluminum wire is a special type of electrical wire. Its main body is an aluminum core, while the outer layer is covered with a certain proportion of copper. This structure combines the lightweight properties of aluminum with the excellent conductivity of copper, making copper-clad aluminum wire widely used in the electrical field. The manufacturing process of copper-clad aluminum wire employs advanced cladding and welding technology, ensuring a strong interatomic metallurgical bond between the copper layer and the aluminum core. This allows the two metal materials to become an inseparable whole, and they can be drawn and annealed like single metal wires. During the drawing process, the copper and aluminum diameters change proportionally, while the volume ratio of the copper layer remains relatively stable. The unique feature of copper-clad aluminum wire lies in its composite properties. It possesses both the high conductivity of copper and the low density of aluminum. This characteristic allows copper-clad aluminum wire to exhibit conductivity similar to pure copper wire when transmitting high-frequency signals (greater than 5MHz), due to the "skin effect" of high-frequency signals. Furthermore, copper-clad aluminum wire also has good welding performance thanks to its outer copper layer, making it widely used in electrical equipment and coaxial cable conductors.

[0003] The drawing process of copper-clad aluminum wire is a crucial processing step. First, high-quality copper-clad aluminum wire material is prepared and placed on the drawing machine's reel for neat arrangement, ensuring smooth transmission during the drawing process. The wire is first lengthened through a forward pull to reduce its diameter. Next, a rough drawing step is performed, further lengthening the wire with a larger tensile force. During this process, the rough drawing ratio and speed must be precisely controlled to ensure wire uniformity and prevent breakage. After rough drawing, the wire undergoes localized annealing. The main purpose of annealing is to refine the material's crystal structure, improving the wire's plasticity and toughness. After annealing, the wire enters the intermediate and fine drawing stages. Intermediate drawing further lengthens the wire with a smaller tensile force, while fine drawing uses an even smaller tensile force to ultimately lengthen the wire to the required dimensions. Finally, the drawn copper-clad aluminum wire undergoes a quality inspection, including checking the wire diameter, surface quality, and tensile uniformity. During the process, tension adjustment equipment is needed to regulate the tension of the raw material during wire drawing. However, in practical applications, the inventors discovered that the suspension rod on the tension adjustment equipment often "wobbles" due to factors such as the wire and tension control. Under normal circumstances, this "wobbling" does not have much impact on the wire harness. However, when the wire harness tension fluctuates significantly, the frequency and amplitude of the "wobbling" of the suspension rod increase. Although this "wobbling" does not cause the suspension rod to adjust as a whole (the suspension rod will only adjust its angle when the tension is adjusted), a large frequency and amplitude of the suspension rod "wobbling" will affect product quality. Specifically, the suspension rod wobbling may cause unstable wire tension, which in turn affects the dimensional accuracy, surface quality, and mechanical properties of the copper-clad aluminum wire. For example, the wobbling may cause defects such as scratches and pits on the wire surface, or inconsistent wire diameters. On the other hand, the suspension rod wobbling may cause wire breakage and jamming during the wire drawing process, requiring operators to frequently stop the machine for adjustments, thereby reducing production efficiency.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This copper-clad aluminum wire tension device uses multiple buffer panels in contact with the surface of the boom to cushion the boom's sway. Simultaneously, the sliding plate frame and buffer springs absorb the force of the swaying motion, effectively reducing the boom's sway. Furthermore, by combining the timing of the button's touch, the sway frequency of the boom can be accurately determined, allowing staff to monitor the boom's sway condition.

[0018] This copper-clad aluminum wire tensioning device limits the movement of the sliding shaft by adjusting the groove, thereby causing the actuating shaft to drive the force-applying rod frame and the contact shaft on it to make corresponding angle adjustments under the action of the sliding plate frame. By calculating the time difference between two adjacent touches of the timing button, the swaying frequency of the boom can be effectively determined.

[0019] This copper-clad aluminum wire tension device uses a detection shaft and a ball at its end to effectively detect the degree of bending of the boom. Under the action of the spring mechanism, when the boom bends significantly, the pressure shaft will contact the sensing element and act on it. This causes the sensing element to send information to the terminal in the form of an electrical signal, allowing staff to understand the degree of bending of the boom and prevent it from bending excessively.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please refer to Figures 1-11. A copper-clad aluminum wire tensioning device is described. This invention addresses the technical problems in the background art by making corresponding improvements. Because the suspension rod 33 on the tension adjusting device 3 has a certain length, and the end adjusting the wire tension is a certain distance from the fixed end (i.e., the drive shaft 32 in the following description), this end of the suspension rod 33 often wobbles during tension adjustment. To address this, this invention includes the following design: a frame 1, multiple winding mechanisms 2 fixedly installed inside the frame 1, and a tension adjusting device 3 fixedly installed inside the frame 1. The tension adjusting device 3 includes a body 3. 1. The drive shaft 32, which is rotatably connected to the body 31, and the suspension rod 33, which is movably connected to the drive shaft 32, are further explained as follows: This tension adjustment device 3 is a prior art structure, and therefore, this invention does not describe it in detail. An annular connecting frame 4 is fixedly installed on the drive shaft 32, and a support plate frame 41, which is slidably connected to the body 31, is fixedly installed on the annular connecting frame 4. Therefore, when the suspension rod 33 adjusts the tension of the wire harness, i.e., the drive shaft 32 drives the suspension rod 33 to adjust its angle accordingly, the annular connecting frame 4 is fixedly installed on the drive shaft 32, and thus the annular connecting frame 4 moves with the drive shaft 32. The shaft 32 drives the support plate frame 41 to adjust synchronously. Multiple limiting sleeves A5 and B6 are fixedly installed on the support plate frame 41. The limiting sleeves A5 and B6 are symmetrically fixed on the support plate frame 41 with the center line of the lifting rod 33 as the axis. The limiting sleeve A5 is located above the lifting rod 33, and the limiting sleeve B6 is located below the lifting rod 33. A sliding plate frame 7 is installed inside each of the limiting sleeves A5 and B6, and a buffer spring 8 connected to the sliding plate frame 7 is also installed inside each of the limiting sleeves A5 and B6. An extension shaft 71 is installed on each sliding plate frame 7. One end of the extension shaft 71 is located outside the limiting sleeve A5 and the limiting sleeve B6. It should be noted that the extension shaft 71 is rotatably connected to the sliding plate frame 7. A buffer panel 72 is fixedly installed at the outer end of the extension shaft 71, and the buffer panel 72 is in contact with the hanger 33. Furthermore, the buffer panel 72 in this invention is made of rubber to buffer the hanger 33. Since the buffer panel 72 is always in contact with the surface of the hanger 33, when the hanger 33 shakes, the buffer panel 72 can effectively absorb part of the shaking force, effectively reducing the shaking of the hanger 33.

[0034] As described above, and referring to Figures 1-6, since multiple buffer panels 72 are in contact with the surface of the boom 33, when the boom 33 sways, the boom 33 acts on the buffer panels 72, and the buffer panels 72 are subjected to force to drive the sliding plate frame 7 to slide within the limiting sleeve A5 (or limiting sleeve B6) through the extension shaft 71. During this process, the sliding plate frame 7 acts on the buffer spring 8, and the buffer spring 8 plays a buffering role on the sliding plate frame 7, thereby reducing the swaying of the boom 33.

[0035] Furthermore, when the tension adjustment of the wire harness fluctuates greatly or the hanger 33 is bent or worn, the swaying frequency of the hanger 33 will increase. In order to accurately understand the swaying frequency of the hanger 33, the present invention makes the following design: an annular frame 61 is fixedly installed at one end of the limiting sleeve B6, and an action shaft 73 is fixedly installed on the side of the sliding plate frame 7 away from the extension shaft 71. The end of the action shaft 73 penetrates the inner wall of the limiting sleeve B6 and extends into the interior of the annular frame 61. Sliding shafts 74 are symmetrically installed on the sliding plate frame 7, and multiple sliding shafts 74 are provided on the inner wall of the limiting sleeve B6 for... The adjusting grooves 75 define the movement trajectory of the sliding shaft 74 and are interconnected. As a further limitation of the invention, each adjusting groove 75 includes a straight-line descending region 751, a spiral region 752, and a guide plate frame 753. One end of the spiral region 752 is connected to the straight-line descending region 751, and the other end of the spiral region 752 is connected to the straight-line descending region 751 of the adjacent adjusting groove 755. It should be noted that one side of the guide plate frame 753 in this invention is an inclined surface, and the other side is a right-angled surface. Referring to Figure 7, one end of the spiral region 752 is connected to the straight-line descending region 751. The descending region 751 is connected near its highest point, and the other end of the spiral region 752 is connected to the straight descending region 751 near its middle area. The guide plate frame 753 is installed at the connection point between the straight descending region 751 (near its middle area) and the other end of the spiral region 752. The inclined surface of the guide plate frame 753 is close to the highest point of the straight descending region 751, and the right-angled surface is close to the lowest point of the straight descending region 751. In the initial state, i.e., when the boom 33 is not swaying, the sliding shaft 74 on the sliding plate frame 7 is located at the highest point of the straight descending region 751. Furthermore, when… When the sliding plate frame 7 descends, the sliding shaft 74 will move along the trajectory of the straight descent area 751 and pass through the inclined surface of the guide plate frame 753 during the movement. It should be noted that the sliding shaft 74 in this invention is a telescopic shaft. The actuating shaft 73 is fixedly installed at one end inside the annular frame 61 with a force-applying rod frame 731, and a touch shaft 732 is fixedly installed at the end of the force-applying rod frame 731. A timing button 62 is fixedly installed on the inner wall of the annular frame 61, and the timing button 62 is located below the touch shaft 732 and on the movement trajectory of the touch shaft 732.

[0036] Specifically, when the boom 33 wobbles, the buffer panel 72 extends the shaft 71 to drive the sliding plate frame 7 to slide within the limiting sleeve B6. Simultaneously, the sliding shaft 74 on the outer wall of the sliding plate frame 7 descends along the straight-line descent area 751. During descent, the sliding shaft 74 passes the inclined surface of the guide plate and moves to the other side. The actuating shaft 73 on the other side of the sliding plate frame 7 then drives the force-applying rod frame 731 to move synchronously. It should be noted that initially, the timing button 62 is located directly below the force-applying rod frame 731, and the sliding shaft 74 moves within the straight-line descent area 751. During descent, the force-applying lever 731 activates the timing button 62, which begins timing. Subsequently, the sliding plate 7 moves in the opposite direction under the action of the buffer spring 8, i.e., it ascends. At this time, the sliding shaft 74 moves along the trajectory of the straight descent area 751. When it reaches the right-angled surface of the guide plate, it is obstructed, thus moving along the trajectory of the spiral area 752. This causes the sliding plate 7 to adjust its angle within the limiting sleeve B6, which in turn causes the force-applying lever 731 at the end of the shaft 73 to adjust its angle synchronously. At this time, the contact shaft at the end of the force-applying lever 731... Body 732 is no longer directly above the timing button 62, and the sliding shaft 74 enters the initial position of the straight descent area 751 of another adjustment groove 75. Subsequently, the buffer panel 72 continues to drive the extension shaft 71 to descend under the action of the lifting rod 33. That is, the sliding shaft 74 continues to descend along the straight descent area 751 of the adjustment groove 75, repeating the above operation. However, during this descent, the touch shaft 732 will not affect the timing button 62. The touch shaft 732 will only move after the force rod frame 731 and the touch shaft 732 on it rotate one full circle (i.e., 360°) with the sliding plate frame 7. Move the timing button 62 directly above the timing button 62, and then touch the timing button 62 again. The time difference between the touches can effectively determine the swaying frequency of the boom 33. It should be noted that in this invention, when the boom 33 sways, the sliding shaft 74 will always cross the inclined surface of the guide plate. In actual production applications, the length of the adjusting groove 75 needs to be adjusted according to the actual data. For the sake of simplicity, this invention provides a corresponding enlarged description of the length of the adjusting groove 75. Through the structural design of this invention, the swaying frequency of the boom 33 can be effectively determined, thus facilitating the staff to effectively understand the swaying condition of the boom 33.

[0037] As a further extension of the present invention, when impurities or oil stains are present on the surface of the wire harness, the tension adjustment device 3 is prone to wear. The worn suspension rod 33 will, on the one hand, increase the frequency and amplitude of the swaying of the suspension rod 33, and on the other hand, it will easily lead to the breakage of the wire harness. In this regard, the present invention adds an embodiment: a mounting frame 34 is fixedly installed on one side of the body 31, and a rotating shaft 341 is provided inside the mounting frame 34. Both ends of the rotating shaft 341 are fixedly installed with lead screws 342, and the two lead screws 342 rotate in opposite directions. The end of one lead screw 342 is rotatably connected to the inner wall of the mounting frame 34. A servo motor 343 is fixedly installed on the top of the mounting frame 34, and the output end of the servo motor 343 passes through the inner wall of the top of the mounting frame 34 and extends into its interior, and is connected to the other lead screw 342. The end of the rod 342 is fixedly connected, and guide shafts 344 are symmetrically installed inside the mounting frame 34. Each lead screw 342 is equipped with a cleaning mechanism 345, and the cleaning mechanism 345 slides at the upper limit of the guide shaft 344. The cleaning mechanism 345 includes two drive sliders 346. One drive slider 346 is installed on the lead screw 342, and the other drive slider 346 is slidably connected to the guide shaft 344. The drive sliders 346 are connected to each other through a cleaning roller 347, and the cleaning roller 347 is rotatably connected to the drive slider 346. The rotation of the servo motor 343 causes the lead screw 342 to rotate. Since the rotation directions of the threads of the two lead screws 342 are opposite, the drive slider 346 drives the cleaning roller 347 to effectively clean the surface of the wire harness.

[0038] In practical applications, the swaying frequency and amplitude of the suspension rod 33 are also related to its bending condition. Because uneven tension is common during wire drawing, some parts may experience greater tension than others. This causes the suspension rod 33 to bend under the tension of the wire. Normally, small bends do not affect the normal use of the suspension rod 33, but when the degree of bending reaches a certain level, it will exacerbate the swaying frequency and amplitude of the suspension rod 33. Therefore, the present invention incorporates the following design, wherein... A magnetically shielding outer frame 51 is fixedly installed on a limiting sleeve A5, with the magnetically shielding outer frame 51 close to one end of the lifting rod 33. An electromagnetic mechanism 52 is fixedly installed on the inner wall of one end of the magnetically shielding outer frame 51, and a sliding frame 53 is provided on one side of the electromagnetic mechanism 52. The sliding frame 53 slides within the magnetically shielding outer frame 51, and a force-receiving magnetic plate 531 is fixedly installed on the side of the sliding frame 53 close to the electromagnetic mechanism 52. When the electromagnetic mechanism 52 is energized, it generates a repulsive force on the force-receiving magnetic plate 531. A slot 511 is provided at the bottom of the magnetically shielding outer frame 51. An extension plate frame 532, which is slidably connected to the slot 511, is fixedly installed at the bottom of the sliding frame 53. A detection sleeve 54 is fixedly installed on the extension plate frame 532, and the detection sleeve 54 is located above the hanger 33. A return spring 55 is connected between the side of the sliding frame 53 away from the force-bearing magnetic plate 531 and the side wall of the magnetic shielding outer frame 51. An annular plate frame 541 is installed inside the detection sleeve 54, and the annular plate frame 541 is slidably connected to the inner wall of the detection sleeve 54. A spring is also connected between the annular plate frame 541 and the inner wall of the detection sleeve 54. Mechanism 542, and spring mechanism 542 is in a compressed state. A detection shaft 543 is fixedly installed on the side of the annular plate frame 541 away from spring mechanism 542. The end of detection shaft 543 penetrates the inner wall of detection sleeve 54 and extends to the outside. A ball 544 is installed at the end of detection shaft 543 and rotatably connected to it. A pressure shaft 545 is fixedly installed on the annular plate frame 541. A sensing element 546 is installed inside detection sleeve 54. The sensing element 546 is located on the movement trajectory of pressure shaft 545.

[0039] As described above, the operator sets the program to control the electromagnetic mechanism 52 to be energized periodically. The energization of the electromagnetic mechanism 52 generates a repulsive force on the magnetic plate 531, causing the sliding frame 53 to slide within the magnetically shielded outer frame 51. During this process, the return spring 55 is compressed, and the sliding frame 53 drives the detection sleeve 54 to move synchronously via the extension plate 532. Because the ball 544 at the end of the detection shaft 543 is in close contact with the lifting rod 33, and the spring mechanism 542 is compressed, when the lifting rod 33 bends significantly, the annular plate 541, under the action of the spring mechanism 542, will drive the pressure shaft 545 to apply a force to the sensing element 546. 46. ​​Information is sent to the terminal in the form of an electrical signal. Furthermore, under normal conditions, the boom 33 does not sway, and there is a certain distance between the pressure shaft 545 and the sensing element 546. Therefore, when the boom 33 sways to a certain extent, the pressure shaft 545 will not contact the sensing element 546. However, if the boom 33 is bent to a large extent, and swaying occurs, the pressure shaft 545 will contact the sensing element 546 during this process. Thus, through the structural design of the present invention, the degree of bending of the boom 33 can be effectively understood, and the boom 33 can be prevented from bending to a large extent. This can effectively prevent the aggravation of the swaying frequency and amplitude of the boom 33, thereby improving the drawing quality of the copper-clad aluminum wire.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
