Description

Technical Field

[0001] The invention belongs to the technical field of twisting equipment, and in particular relates to a twisting machine. Background Art

[0002] Wire twisting machines are used to twist various soft and hard conductor wires such as copper wire, enameled wire or copper clad aluminum, so that each stranded single wire is twisted together into a whole. Wire twisting is generally divided into two types: concentric layer twisting and bundle twisting. Concentric layer twisting means that each stranded single wire is twisted around the stranded wire in layers and in an orderly manner with the center line of the stranded wire as the axis; bundle twisting means that multiple stranded single wires are twisted together in the same direction and pitch without layers. In the process of twisting, each stranded single wire needs to be unwound and spread from its own coil before twisting.

[0003] During the twisting process, the tension of each strand affects the tightness of the strands. If the tension is too small, the strands will be loose and loose. If the tension is too large, the strands will be broken. However, in existing stranding machines, the tension of each strand is completely adjusted by human experience and touch, which has the defect of poor adjustment accuracy and makes it difficult to keep the tension of each strand consistent.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It should be noted that the terms “setting” and “connection” should be understood in a broad sense. For example, it can be directly setting or connecting, or it can be indirectly setting or connecting through a central component or a central structure.

[0035] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner unless there is any contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in the present invention will not be described separately.

[0036] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a wire twisting machine, which controls each process of the twisting production process by a cabinet, and has good control convenience. The wire twisting machine includes a wire twisting device 1, a wire take-up device 2 and a wire passing buffer device 3. The wire twisting device 1 rotates to twist a plurality of twisted single wires into a twisted wire body. The "twisted single wire" refers to the wire before twisting (such as a conductor wire or silk thread used for twisting), and does not refer to the wire formed after twisting; the wire take-up device 2 is used to collect the twisted twisted wire body, and the collection method can be rolled into a tube shape or bundled; and the wire passing buffer device 3 is used to pull the twisted wire body to transfer the twisted wire body to the wire take-up device 2, so as to realize continuous collection of the twisted wire body. At the same time, under the pulling action of the wire buffer device 3, not only can the twisted wire body obtained after twisting be kept in a tensioned state at all times, which is convenient for stable transmission to the take-up device 2 for collection, but also each twisted single wire can be kept tensioned to maintain a stable twisting state, ensuring that the entire twisting work can be carried out continuously and reliably.

[0037] In the process of gathering and twisting the twisted single wires, it is necessary to first release the wires from their respective coils and keep them in an open state so that they can be smoothly output. During the process of opening and outputting the twisted single wires, the twisted single wires need to be kept in a tensioned state at all times to achieve the purpose of continuous and stable twisting. Therefore, in the embodiment of the present invention, in order to ensure that the tension of each twisted single wire is maintained within a stable and appropriate range, the twisting device 1 is configured to include a release device 11 (refer to Figure 1 ), since multiple twisted single wires need to be provided during the twisting process, multiple unwinders 11 are provided, and each unwinder 11 is used to open and output a single twisted single wire separately. The open output refers to opening the twisted single wire in the winding state and outputting it in a taut state. Since the unwinder 11 can accurately adjust the tension and can intuitively know the value of the tension. Therefore, by providing the unwinder 11, the autonomous and accurate adjustment of the tension of the twisted single wire is achieved. In addition, the accuracy and convenience of adjustment when the tension of each unwinder 11 is kept consistent are improved, and the defect of poor accuracy of keeping the tension of each unwinder 11 consistent by relying entirely on human experience is overcome. Since the tension of each unwinder 11 can be kept consistent through adjustment, the balanced twisting of each twisted single wire is achieved, so that the tightness of the twisted wire body obtained after twisting is kept uniform and consistent, and the quality of the product after twisting is improved.

[0038] like Figure 3 and Figure 4 As shown, the stranding device 1 (refer to Figure 1) also includes a chassis 12, a twisting drum 13 and a twisting driving member 14. The chassis 12 is used for fixing and installing each unwinder 11 and the twisting drum 13. Each unwinder 11 is distributed on the chassis 12 and preferably fixed on the chassis 12 in a uniformly distributed manner. Each twisted single wire output by each unwinder 11 is connected to the twisting drum 13, and the twisting drum 13 gathers each twisted single wire into one strand above the twisting drum 13. It is preferred that the twisting drum 13 is set at the center of the area formed by the combination of each unwinder 11 to ensure that each twisted single wire is subjected to balanced force and achieve balanced twisting. During the twisting process, the twisting drive 14 provides power to drive the chassis 12 to rotate, so that each unwinder 11 can rotate around the twisting drum 13. At the same time, the twisting drum 13 itself also rotates synchronously with the chassis 12. Each unwinder 11 and the twisting drum 13 remain relatively still, so that each twisted wire can be twisted into one body to achieve the twisting of the twisted wire body. Under the continuous pulling of the wire buffer device 3, each twisted single wire can be continuously twisted, and the twisted wire body obtained by twisting is promptly transported to the take-up device 2 for collection. In this way, the twisting machine realizes the synchronous output, twisting and collection of the twisted wire body after twisting of the twisted single wire, and achieves the production purpose of continuous twisting. In this embodiment, the twisting drive 14 is a motor, and the rotation of the chassis 12 is realized by belt transmission.

[0039] like Figure 4 and Figure 5 As shown, the unwinder 11 includes a support seat 111, a mounting frame 118, a wire reel mounting shaft 112 and a conductor wheel assembly 113. The support seat 111 is fixedly connected to the chassis 12, and the mounting frame 118 is connected to the support seat 111 for installation and connection of the wire reel mounting shaft 112. The wire reel mounting shaft 112 is fixed on the mounting frame 118, and is used to connect a wire reel wound with twisted single wires. According to the production method, each twisted single wire is initially wound on a wire reel. Therefore, by providing the wire reel mounting shaft 112, it is convenient to load and fix the wire reel, so as to realize the continuous supply of twisted single wires. The conductor wheel assembly 113 is fixed on the support seat 111, and is used to guide the output of the twisted single wire wound on the wire reel, ensuring that the output twisted wire body can be accurately and smoothly transported to the stranding drum 13. In the embodiment of the present invention, in order to ensure that the wire coil always maintains tension when outputting the twisted single wire and prevent the wire coil from becoming loose, a tension regulator 114 for adjusting the tension of the twisted single wire output is connected to the wire coil installation shaft 112. The tension regulator 114 generates a torsion force in the opposite direction of the twisted single wire output, and the torsion force acts directly on the wire coil, so that the problem of the output twisted single wire becoming loose due to the excessive rotation of the wire coil can be avoided during the wire coil unwinding process, and the twisted single wire is always kept in a tensioned state, ensuring stable and smooth output.

[0040] The setting of the tension regulator 114 can realize the accurate adjustment of the tension of the twisted single wire output, and the tension regulator 114 has a scale that directly displays the tension. In this way, in the tension adjustment operation, after adjusting the tension of one unwinder 11, other unwinders 11 can refer to the value for adjustment, thereby improving the efficiency and accuracy of the tension adjustment of each unwinder 11. It eliminates the error caused by adjusting the tension based on experience and feel, which leads to the problem of unstable product quality. The tension of each twisted single wire is consistent, and balanced twisting is achieved.

[0041] like Figure 5 As shown, the tension regulator 114 includes a main body 1141 and a resistance adjusting member 1143. The main body 1141 is connected to the mounting frame 118, and is used to generate a torque opposite to the output direction of the twisted single wire, and the main body 1141 is connected to the wire coil mounting shaft 112 through a connecting member 1144, and the connecting member 1144 can be a coupling or a connecting sleeve, etc. The resistance adjusting member 1143 is arranged on the main body 1141, and is used to adjust the magnitude of the torque generated by the main body 1141 to meet the different requirements for the tension of the twisted wire when twisting different types of twisted wire bodies. In this embodiment, the tension regulator 114 is a magnetic damper, which can provide stable and balanced torque, and the twisting size is easy to adjust.

[0042] like Figure 5 As shown, the wire wheel assembly 113 includes a first guide wheel 1131, a second guide wheel 1132 and a guide assembly 1133. The first guide wheel 1131 is used for winding the twisted single wire output from the wire reel; the second guide wheel 1132 is used for winding the twisted single wire after passing through the first guide wheel 1131; and the guide assembly 1133 is used to guide the twisted single wire after passing through the second guide wheel 1132 to pass through the twisted wire drum 13 (refer to Figure 3 ) connection. And, wherein, the first guide wheel 1131 and the second guide wheel 1132 are both fixedly connected to the support seat 111 through the connecting frame 115, and the guide assembly 1133 is arranged above the wire coil through the support plate 116. Through such an arrangement, when performing winding connection, the twisted single wire output from the wire coil is first wound on the first guide wheel 1131, and then wound on the second guide wheel 1132, and finally passed through the guide assembly 1133 and connected to the stranded wire drum 13. After being guided by the various components in the wire wheel group 113, the output of the twisted single wire is stable and smooth. In this embodiment, the first guide wheel 1131 and the second guide wheel 1132 are ceramic rings with a smooth surface and low hardness. In this way, the ceramic ring can not only provide guidance for the output of the twisted single wire, but also ensure that the twisted single wire will not be damaged during the sliding process of the twisted single wire wrapped on the ceramic ring.

[0043] like Figure 5As shown, since the first guide wheel 1131 and the second guide wheel 1132 are fixedly supported by the connecting frame 115, and the connecting frame 115 is connected to the support seat 111. Therefore, the mounting frame 118 can be fixed on the connecting frame 115, and the fixed installation of the mounting frame 118 can also be achieved.

[0044] like Figure 5 As shown, in the embodiment of the present invention, two opposing stop bars 117 are further provided on the mounting frame 118, and the twisted single wire output from the wire coil passes through between the two stop bars 117 and then is wound on the first guide wheel 1131. In this way, under the limiting effect of the two stop bars 117, it is ensured that the position of the twisted single wire wound on the first guide wheel 1131 remains relatively stable and will not fall off from the first guide wheel 1131.

[0045] like Figure 3 and Figure 4 As shown, the wire stranding device 1 further includes a detection switch 15 and a wire break detection assembly 16. The detection switch 15 is arranged adjacent to the support seat 111 through the support rod 18. In a specific arrangement, the wire stranding machine is provided with a bottom plate 10 to install the support chassis 12, so that the support rod 18 is fixed on the bottom plate 10. The wire break detection assembly 16 is movably connected to the mounting frame 118 (refer to Figure 5 ) is used to compress the twisted single wires and can touch the detection switch 15 when the wire is broken, triggering the detection switch 15 to cut off the power and stop twisting. Figure 5 , the wire break detection assembly 16 includes a wire pressing wheel 161 for pressing the twisted single wire, a contact rod 162 for contacting the detection switch 15, a torsion spring 163, an adjusting gear 164 and a mounting rod 165. The magnitude of the force applied by the wire pressing wheel 161 on the twisted single wire is provided by the torsion spring 163, and the magnitude of the pressure can be adjusted by adjusting the gear 164. The torsion spring 163 is sleeved on the mounting rod 165, the adjusting gear 164 is connected to one end of the mounting rod 165, and the adjustment of the torque generated by the torsion spring 163 is achieved in combination with the lever 166. The mounting rod 165 is connected to the mounting frame 118 and supported and fixed by the mounting frame 118. In this way, the torsion spring 163 generates pressure to press the wire pressing wheel 161 on the twisted single wire, and the twisted single wire is pressed. At this time, the contact rod 162 is raised and cannot touch the detection switch 15 during the rotation process. When the twisted single wire is broken, the wire pressing wheel 161 will drop, thereby driving the contact rod 162 to drop, so that the position of the contact rod 162 can touch the detection switch 15. After touching the detection switch 15 during the rotation process, the circuit connected to the detection switch 15 will form a loop, which serves to remind the disconnection. This setting method realizes accurate detection of disconnection. In this embodiment, the wire pressing wheel 161 is arranged between the first guide wheel 1131 and the second guide wheel 1132.

[0046] In the specific twisting process, in addition to the torsion force of twisting the strands, each strand will also generate a torsion internal stress opposite to the twisting direction. The existence of the torsion internal stress can easily cause the shape of the stranded wire to be unstable, resulting in the loosening of the stranded wire. Therefore, the stranding device 1 also includes a detwisting component 17 (see FIG. 1 ) disposed in the chassis 12 for eliminating the torsion internal stress of the stranded wire. Figure 2 ), under the action of the back-twisting component 17, the back-twisting operation of each twisted single wire can be achieved during the twisting process, avoiding the loosening of the twisted wire body after twisting, thereby ensuring the good quality of the twisted wire body.

[0047] like Figure 3 and Figure 6 As shown, the backtwist assembly 17 includes a backtwist drive 171, a driving gear 172 and a planetary gear 173 for connecting to a support seat 111. Each support seat 111 is connected to a planetary gear 173, and the planetary gear 173 is connected to the driving gear 172 through a transition gear 174. At the same time, the backtwist drive 171 is connected to the driving gear 172 through a backtwist transmission member. In this way, in the specific backtwist process, the driving force generated by the backtwist drive 171 is transmitted to the driving gear 172 through the backtwist transmission member, and the rotation of the driving gear 172 can drive the transition gear 174 to rotate, and then under the transmission action of the transition gear 174, the planetary gears 173 are rotated at the same time, and then the support seats can be rotated to realize the backtwist of each twisted single wire. This backtwist is carried out by the mutual meshing transmission between gears, and the synchronization is good, ensuring that each unwinder 11 can rotate at the same time to achieve synchronous backtwist.

[0048] like Figure 3 and Figure 6 As shown, in the embodiment of the present invention, ten pay-off devices 11 are arranged on the chassis 12, so that transmission can be realized by adopting a mode of sharing a transition gear 174 between every two planetary gears 173, which can also realize synchronous transmission and improve the simplicity of the structure. Of course, in other embodiments, the transmission can be realized by selecting a combination of sharing and individually setting the transition gear 174 according to the number of pay-off devices 11 arranged on the chassis 12, and the setting flexibility is good.

[0049] In the embodiment of the present invention, the stranding machine realizes stranding transmission and back-twisting transmission respectively by arranging a main shaft at the center of the chassis 12, and arranging a stranding transmission member and a back-twisting transmission member on the main shaft. This method realizes the stranding and back-twisting functions of each stranded single wire by sharing a main shaft, has a simple structure, and is ingeniously arranged.

[0050] like Figure 1 and Figure 2As shown, in an embodiment of the present invention, the wire twisting machine is mainly used for concentric layer twisting. Therefore, the wire twisting machine includes two wire twisting devices 1, which are stacked up and down and remain coaxial. In this way, in the actual twisting process, the lower wire twisting device 1 can be used to twist the stranded wire, and then the upper stranded single wires can be layered and orderly twisted around the stranded wire by the upper wire twisting device 1, thereby realizing the overall twisting of the stranded wire body. In the actual setting, the number of wire unwinders 11 in the upper and lower wire twisting devices 1 can be selected according to specific production needs, and can be kept consistent or different. In an embodiment of the present invention, refer to Figure 3 and Figure 4 The structural difference between the upper and lower stranding devices is that the number of wire unwinders 11 is different. The stranding device 1 located on the upper layer is provided with ten wire unwinders 11, and the stranding device 1 located on the lower layer is provided with three wire unwinders 11. Of course, it can be understood that in the actual stranding process, not all wire unwinders 11 must be stranded at the same time, and the number of wire unwinders 11 used can be selected according to the actual stranding requirements. At the same time, the stranding machine can set the number of stranding devices 1 according to the specific stranding type requirements, and it is not just two stranding devices stacked, but can also be stacked to three or four or other numbers. In addition, the working mode of each stranding device 1 can also be selected as needed, which can be to make each stranding device 1 stranded at the same time, or to choose to strand separately. Moreover, when more than two stranding devices 1 are used for stranding at the same time, the stranding directions can be opposite or the same. The specific stranding method is selected according to the actual production needs and is not limited here.

[0051] like Figure 1 and Figure 2 As shown, the stranding machine also includes a housing 4 and a slide assembly 5 for adjusting the stranding density of the stranded wire body. Figure 7 The slide assembly 5 includes a slide frame 51, a wire die 52, and a slide frame driving member 53 for driving the slide frame 51 to move up and down. The slide frame driving member 53 is fixed on the housing 4. The slide frame 51 is provided with a wire die groove 54. The wire die 52 is installed in the wire die groove 54. The wire die 52 is provided with a wire hole 521 for the stranded wire body to pass through. Through such a setting, each stranded single wire can be gathered in the wire hole 521, so that in the process of stranding, the wire hole 521 can be used to limit the position of each stranded single wire to be finally stranded. In this way, under the drive of the slide frame driving member 53, the position of the slide frame 51 can be adjusted as needed, and then the position of the wire die 52 can be adjusted. When the wire die 52 is away from the stranding barrel 13, the tightness of the obtained stranded wire body is relatively loose; and when the wire die 52 is close to the stranding barrel 13, the stranded wire body is relatively tight. In this way, the stranding of different types of stranded wire bodies is realized, and the production direction is wide.

[0052] like Figure 7 As shown, in the specific setting, in order to improve the convenience of threading, the wire mold 52 is set to include two interconnected wire mold monomers 522, and the wire hole 521 is formed between the two wire mold monomers 522. In this way, the wire mold 52 is composed of two dispersed wire mold monomers 522, so that the twisted wire body is placed between the two wire mold monomers 522, and then the two wire mold monomers 522 are combined and connected as a whole to achieve fast threading. In this setting mode, a wire passing groove connected to the wire mold groove 54 is opened on the sliding frame 51. In order to meet the operation of threading the twisted wire body into the wire hole 521, the twisted wire body is first allowed to enter the wire mold groove 54 through the wire passing groove, and then the two wire mold monomers 522 are combined and connected.

[0053] like Figure 7 As shown, in the embodiment of the present invention, the line buffer device 3 includes a mounting plate 31, and the mounting plate 31 is fixedly connected to the housing 4 (refer to Figure 1 ). The wire buffer device 3 also includes a wire routing wheel 32, a ceramic sleeve 33, a rubber-coated wheel 34 and a wire-passing tension adjustment assembly 35, which are respectively fixed on the mounting plate 31 in sequence along the output direction of the stranded wire body. The rubber-coated wheel 34 is connected to a rubber-coated wheel driving component 36 for driving the rubber-coated wheel 34 to rotate. The wire routing wheel 32, the ceramic sleeve 33, the rubber-coated wheel 34 and the wire-passing tension adjustment assembly 35 are fixed on the same side of the mounting plate 31, and the rubber-coated wheel driving component 36 is fixed on the reverse side of the mounting plate 31. Through such an arrangement, the stranded wire body passed through the wire mold 52 is first wound on the wire routing wheel 32, then wound on the ceramic sleeve 33, and then wound on the rubber-coated wheel 34, and finally transported to the wire take-up device 2 (refer to Figure 2 ). In the specific wire passing process, the rubber-coated wheel driving member 36 drives the rubber-coated wheel 34 to rotate, thereby pulling the stranded wire body, realizing the pulling of the stranded wire body during the twisting process, and conveying the stranded wire body to the take-up device 2. At this time, the take-up device 2 operates synchronously to realize the collection of the stranded wire body. In order to improve the reliability of pulling out the stranded wire body, the rubber-coated wheel 34 is made of a material with high friction, and at the same time, the stranded wire body is arranged on the wire-guiding wheel 32 in a manner of winding multiple turns. Thereby, the contact area between the stranded wire body and the rubber-coated wheel 34 and the wire-guiding wheel 32 can be increased, the friction force is improved, and reliable pulling can be achieved.

[0054] like Figure 7 As shown, after being pulled by the rubber-coated wheel 34, the stranded wire body needs to be wound on the wire tension adjustment component 35 and then transmitted to the wire take-up device 2. Under the monitoring of the detection sensor, the wire tension adjustment component 35 can monitor the tightness of the stranded single wire winding in real time to ensure that the tension of the output stranded wire body is always kept within a suitable range.

[0055] like Figure 8 As shown, the wire-taking device 2 includes a wire-taking drive 21, a reducer 22, a wire-arranging device 23 and a wire-arranging drum 24. The reducer 22 and the wire-arranging device 23 are fixed on the housing 4. The drive is connected to the reducer 22, and the wire-arranging drum 24 is connected to the wire-arranging device 23. At the same time, the reducer 22 and the wire-arranging device 23 are connected by a transmission belt 25. The rotating shaft of the reducer 22 is connected to the wire-taking drum 7, and the wire-taking drum 7 rotates synchronously with the rotating shaft, so that the stranded wire body can be continuously wound on the wire-taking drum 7. In the actual wire-taking process, the stranded wire body first passes through the wire-arranging drum 24 and then is wound on the wire-taking drum 7, and the wire-arranging device 23 drives the wire-arranging drum 24 to move back and forth, and arranges the position of the winding of the stranded wire body so that the stranded wire body can be evenly wound on the wire-taking drum 7.

[0056] like Figure 2 As shown, since the wire passing buffer device 3 and the wire taking-up device 2 are respectively arranged on the inner and outer sides of the housing 4, it is necessary to open a through hole 41 on the housing 4 (refer to Figure 1 ) for the stranded wire to pass through and connect to the take-up device 2. Therefore, in order to ensure that the stranded wire passes through the through hole 41 smoothly and safely, the stranding machine is configured to also include a routing assembly 6 (refer to Figure 1 The wire routing assembly 6 is disposed between the wire passing buffer device 3 and the wire taking-up device 2, and is used to guide the stranded wire body from the wire passing buffer device 3 to the wire taking-up device 2. In this way, under the guidance of the wire routing assembly 6, the stranded wire body can be prevented from contacting the edge of the through hole 41, so that the stranded wire body can be reliably output and collected.

[0057] In the wire twisting machine provided in the embodiment of the present invention, the wire twisting device 1 twists a plurality of twisted single wires into a twisted wire body, and under the pulling action of the wire passing buffer device 3, the twisted wire body is transferred to the wire taking-up device 2 for collection. The wire twisting device 1 is configured to include a wire unwinder 11, and the wire unwinder 11 can not only open and output the twisted single wires, but also adjust the tension of each twisted single wire. In this way, the setting of the wire unwinder 11 realizes accurate adjustment of the tension, and the tension value can also be intuitively known. Thereby, the accuracy and convenience of adjustment when the tension of each unwinder 11 is kept consistent are improved, and the defect of poor accuracy existing in keeping the tension of each unwinder 11 consistent by relying entirely on human experience is overcome. The tension adjustment of the unwinder 11 is convenient and accurate, so that the wire twisting machine can achieve balanced twisting and ensure the stability of product quality.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
