Description

Technical Field

[0001] The present invention relates to the technical field of stranding machines, and particularly relates to a frame-type stranding machine equipped with an adaptive tension adjustment structure. Background Art

[0002] A stranding machine is an important device in the wire and cable manufacturing industry. Its working principle is to rotate a stranding device to twist multiple single-wire conductors into one or more strands of stranded wire in a certain stranding direction and pitch, forming a wire and cable product with certain structure and performance, which is widely used in the production fields of wire and cable, overhead line, optical fiber cable, etc.

[0003] In the prior art, when feeding the material from the coiling cylinder, there is a lack of an effective clamping device to fix the remaining conductors. There are already partially stranded conductors or cables between the rotating cage and the stranding die. Since this part of the conductors is not clamped and fixed, it is very easy to become loose and deformed. When a new coiling material is put on the line, due to the looseness of the previously stranded part, the tension system is difficult to quickly return to a stable state, so that the tension of the new coiling material during the stranding process is unstable, affecting the tightness and uniformity of stranding, and further reducing the quality of the wire and cable product. Summary of the Invention

[0004] Aiming at the above-mentioned disadvantages of the prior art, the present invention provides a frame-type stranding machine equipped with an adaptive tension adjustment structure, which can effectively solve the problems in the prior art that when feeding the material from the coiling cylinder, there is a lack of an effective clamping device to fix the remaining conductors, there are already partially stranded conductors or cables between the rotating cage and the stranding die, and since this part of the conductors is not clamped and fixed, it is very easy to become loose and deformed. When a new coiling material is put on the line, due to the looseness of the previously stranded part, the tension system is difficult to quickly return to a stable state, so that the tension of the new coiling material during the stranding process is unstable, affecting the tightness and uniformity of stranding, and reducing the quality of the wire and cable product.

A wire passing hole is opened inside one of the rotating plates close to the stranding part, and a clamping assembly for fixing the conductor is arranged inside this rotating plate;

[0008] Among them, the clamping assembly includes a fixed clamping plate disposed inside the placement cavity. The outer surface of the fixed clamping plate is fixedly connected to one side of the rotating plate away from the wire twisting member, and a reciprocating clamping plate is slidably connected to one side of the rotating plate close to the fixed clamping plate. The fixed clamping plate and the reciprocating clamping plate are distributed on both sides of the wire threading hole, and arc-shaped grooves are formed on the outer surfaces of the fixed clamping plate and the reciprocating clamping plate close to the wire threading hole.

[0009] Further, it further includes a blanking part. The blanking part includes a moving seat.

A blanking fork is slidably connected to one side of the moving seat close to the rotating frame, and a moving member for pushing the reciprocating clamping plate to move is provided on one side of the blanking fork close to the rotating frame.

[0010] Further, two fixed clamping plates and two reciprocating clamping plates are provided. A connecting block is fixedly connected between the two fixed clamping plates, and the fixed clamping plates and the reciprocating clamping plates are arranged in an alternating manner. One side of the two reciprocating clamping plates away from the fixed clamping plate is fixedly connected through a connecting plate, and the outer surface of the connecting plate is slidably connected to a buckle fixed on the inner wall surface of the connecting plate.

[0011] Further, the moving member includes a pressure plate that fits on the outer surface of the connecting plate.

[0012] Further, a magnetic plate is provided on one side of the buckle away from the fixed clamping plate, and the one side of the connecting plate away from the fixed clamping plate is designed with a magnetic connection with the outer surface of the magnetic plate.

The clamping structure can ensure the stability of the cable that has been partially stranded between the rotating plate and the outer end stranding die, and avoid the occurrence of situations such as loosening and deformation of this part of the cable. After the operation of loading the new bobbin is completed, the new and old wires are connected near the wire dividing block. At this time, the clamping assembly divides the wire into two parts: the new wire and the old wire. Among them, the new wire covers the interval from the start of the bobbin to the joint, while the old wire extends from the joint to the outer end stranding die. Then, the tension of the new wire is finely restored by means of the tension adjusting member. In this way, when the clamping assembly is loosened, the new wire can achieve a seamless and smooth transition with the old wire, ensuring the coherence and stability of the wire connection process, effectively avoiding various problems caused by sudden changes in tension or poor connection. After the clamping assembly is loosened, the tension system can quickly return to a stable state, so that the tension of the new coil is stable during the stranding process, ensuring the tightness and uniformity of the stranding, and improving the quality of the cable product.

[0033] Embodiment:

[0034] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a frame-type wire twisting machine equipped with an adaptive tension adjustment structure, including:

[0035] Placing part 1, the placing part 1 includes a support frame 11 fixed above the base. The support frame 11 is rotatably connected with a rotating plate 12 through a bearing arranged inside it. A rotating frame 13 is fixedly connected between the two rotating plates 12. The placing cavity 131 and the driving cavity surrounded by the rotating frame 13 are distributed staggeredly. The two side walls of the placing cavity 131 are designed in parallel. The base is rotatably provided with a wire twisting part 17 fixedly connected to the outer surface of the rotating plate 12 through a fixing frame arranged on its upper surface. A wire passing hole 121 is opened inside one of the rotating plates 12 close to the wire twisting part 17, and a clamping assembly 14 for fixing the wire is arranged inside this rotating plate 12; There are four placing cavities 131 and driving cavities respectively. The placing cavity 131 is used for placing wire coiling drums. The wire twisting part 17 includes a wire twisting die inside, which can twist multiple single-strand wires into one or more stranded wires according to a certain twisting direction and pitch.

[0036] Among them, the clamping assembly 14 includes a fixed clamping plate 141 arranged inside the placing cavity 131. The outer surface of the fixed clamping plate 141 is fixedly connected to the side of the rotating plate 12 away from the wire twisting part 17. A reciprocating clamping plate 142 is slidably connected to the side of this rotating plate 12 close to the fixed clamping plate 141. The fixed clamping plate 141 and the reciprocating clamping plate 142 are distributed on both sides of the wire passing hole 121. Arc-shaped grooves are opened on the outer surfaces of the fixed clamping plate 141 and the reciprocating clamping plate 142 close to the wire passing hole 121.

[0037] It further includes a blanking part 2. The blanking part 2 includes a moving seat 21. The base is slidably connected to the bottom of the moving seat 21 through a slide rail opened on its upper surface. A blanking fork 22 that fits against the bottom of the external wire coiling drum is slidably connected to the side of the moving seat 21 close to the rotating frame 13. A moving part 23 for pushing the reciprocating clamping plate 142 to move is arranged on the side of the blanking fork 22 close to the rotating frame 13. A plurality of notches are opened inside the blanking fork 22 to facilitate simultaneous blanking of multiple coiling drums on one side.

[0038] There are two fixed clamping plates 141 and reciprocating clamping plates 142 respectively. A connecting block is fixedly connected between the two fixed clamping plates 141, and the fixed clamping plates 141 and the reciprocating clamping plates 142 are distributed staggeredly. The sides of the two reciprocating clamping plates 142 away from the fixed clamping plates 141 are fixedly connected through a connecting plate 143. The outer surface of the connecting plate 143 is slidably connected to a buckle fixed on the inner wall surface of the connecting plate 143.

[0039] The moving member 23 includes a pressing plate 231 that fits against the outer surface of the connecting plate 143. The pressing plate 231 is fixedly connected to the outer surface of the blanking fork 22 through a reinforcing rib plate provided on its outer surface. A reciprocating clamping plate 142 near one side of the wire threading hole 121 is slidably connected with a limiting post 232 through a receiving groove opened on its upper surface. A spring connected to the lower surface of the limiting post 232 is provided at the bottom end of the inner wall of the receiving groove. The side of the connecting block near the reciprocating clamping plate 142 is designed with an inclined surface, and the top end of the limiting post 232 is designed to fit against the inclined surface of the connecting block.

[0040] A magnetic plate 144 is provided on the side of the buckle away from the fixed clamping plate 141. The side of the connecting plate 143 away from the fixed clamping plate 141 is designed with a magnetic property that magnetically connects with the outer surface of the magnetic plate 144.

[0041] A rubber block 145 is fixedly connected to the inner wall surface of the arc-shaped groove, and a groove is opened on the outer surface of the rubber block 145. The groove is opened along the outer surfaces of the fixed clamping plate 141 and the reciprocating clamping plate 142, which can prevent the internal wire from twisting.

[0042] A wire dividing block 15 fixedly connected to the outer surface of the rotating frame 13 is provided inside the moving cavity. A wire dividing hole 151 is opened inside the wire dividing block 15. The wire dividing block 15 is provided with a cutting member 16 through a sliding cavity opened inside it. The wire dividing hole 151 is communicated with the inside of the sliding cavity.

[0043] The cutting member 16 includes a cutting plate 161. The cutting plate 161 is slidably connected through a sliding groove opened inside the wire dividing block 15. A tension spring 162 connected to the outer surface of the cutting plate 161 is provided on the inner wall surface of the sliding groove. A lifting plate 163 that fits against the inclined surface of the cutting plate 161 is slidably connected inside the wire dividing block 15. A connecting rod 164 is fixedly connected to the outer surface of the lifting plate 163. A lifting plate 165 is fixedly connected to the side of the blanking fork 22 near the cutting plate 161. A cutting edge for cutting the wire is opened on the side of the cutting plate 161 away from the lifting plate 165.

[0044] A tension adjusting member is provided inside the driving cavity. The tension adjusting member can ensure that the coil material always maintains an appropriate and stable tension during the unwinding process, prevent the coil material from being pulled apart due to excessive tension, or prevent problems such as slack and disordered wires due to too small tension, and ensure the tightness and uniformity of the twisted wires.

[0045] Four groups of wire threading holes 121 are provided inside the rotating plate 12 and are circumferentially arrayed around the rotating plate 12. Correspondingly, four groups of clamping assemblies 14 and wire dividing blocks 15 are provided, and are respectively located on one side near the wire twisting member 17 inside the four placing cavities 131.

[0046] The process of fixing the wire:

[0047] In practical applications, when it is detected that a wire coil inside the stranding machine is about to run out, the driving unit drives the rotating frame 13 and the rotating plate 12 to stop rotating inside the support frame 11, and aligns any one of the placement cavities 131 with the direction where the moving seat 21 is located, so that the bottom of the wire coil material inside the placement cavity 131 is parallel to the upper surface of the blanking fork 22. During this process, the tension adjusting member inside the driving cavity keeps each wire coil material stable, and an electronic control system and actuators such as motors are used to adjust the tension to avoid continuous rotation under the action of inertia. At this time, each wire coil material remains stable, and there is still a part remaining inside it. It passes through the remaining wire dividers inside the placement cavity 131, through the wire dividing block 15, between the fixed clamping plate 141 and the reciprocating clamping plate 142, and finally reaches the stranding member 17 through the wire passing hole 121 inside the rotating plate 12. After multiple strands of wires reach here, they enter the stranding die and are stranded into a whole.

[0048] A driving unit is arranged inside the driving cavity, and the tension adjusting member is placed inside the driving unit. The output end of the driving unit penetrates through the rotating frame 13 and is connected with a rotating seat. The rotating seat is inside the movable cavity, which is used to fix the axis position of the external wire coil material and drive the external wire coil material to rotate. The circumferential diameter of the rotating seat is smaller than the diameter of the bottom of the external wire coil cylinder, and the distance between the fork slots of the blanking fork 22 is larger than the diameter of the rotating seat and smaller than the diameter of the external wire coil cylinder.

[0049] In the initial state, taking the placement cavity 131 on the side close to the moving seat 21 in the stopped state as an example, the outer surface of the connecting plate 143 is closely attracted to the outer surface of the magnetic plate 144, driving the two reciprocating clamping plates 142 to be on the side farthest from the fixed clamping plate 141 (within the stroke range of the reciprocating clamping plate 142). The magnetic force received by the connecting plate 143 is greater than the gravity of the reciprocating clamping plate 142 and the connecting plate 143. Under the action of the tension spring 162, the cutting plate 161 in the cutting member 16 is on the side close to the lifting plate 163 within this forming range, and the cutting plate 161 is in contact with the inclined surface of the lifting plate 163. The lifting plate 163 is at the bottommost end within its forming range. And the distance between the reciprocating clamping plate 142 and the fixed clamping plate 141 inside each placement cavity 131 is the largest, and the cutting plates 161 are all on the side close to the lifting plate 163, being in a contracted state, avoiding damage to the wire by the cutting edge of the cutting plate 161.

[0050] Start the slide rail inside the starting base, driving the moving seat 21 to move towards the rotating frame 13. At this time, the lower surface of the blanking fork 22 is slightly higher than the bottom of the inner wall of the placement cavity 131 at the corresponding position and lower than the bottom of the wire coiling cylinder. As the distance between the blanking fork 22 and the axis of the rotating frame 13 decreases, the adjacent surfaces of the pressure plate 231 and the connecting plate 143 approach until the fork slot of the blanking fork 22 starts to enter the periphery of the rotating seat. At this time, the pressure plate 231 at the outer end of the blanking fork 22 contacts the outer surface of the connecting plate 143. As the moving seat 21 continues to move, the pressure plate 231 pushes the connecting plate 143 towards the axis of the rotating frame 13.

[0051] The connecting plate 143 is fixedly connected to the two reciprocating clamping plates 142, driving them to move towards the fixed clamping plate 141 together under the action of the buckle. The arc-shaped groove of the fixed clamping plate 141 is at the same position as the wire threading hole 121. When the adjacent surfaces of the fixed clamping plate 141 and the reciprocating clamping plate 142 start to coincide, the arc-shaped grooves opened on their adjacent surfaces form a circular hole with the same size as the wire threading hole 121. As the reciprocating clamping plate 142 continues to move, the rubber block 145 on the inner wall of its arc-shaped groove first contacts the tensioned wire and drives multiple wires inside to approach the arc-shaped groove of the fixed clamping plate 141 at the same time. The arc-shaped grooves opened on their adjacent surfaces start to coincide, and the area of the formed circular hole gradually decreases.

[0052] At the same time, the arc-shaped surface at the top of the limiting post 232 in the extended state fits with the inclined surface of the connecting block. The spring at the bottom of the limiting post 232 is subjected to extrusion pressure and undergoes elastic deformation. The limiting post 232 gradually moves downward until the top of the limiting post 232 no longer contacts the inclined surface but contacts the flat surface of the inner wall of the connecting block. At this time, both the fixed clamping plate 141 and the rubber block 145 inside the reciprocating clamping plate 142 are in contact with the outer surface of the wire. The rubber block 145 starts to deform and stably fixes the wire inside the clamping assembly 14 through the grooves opened on its outer surface. At this time, the two fixed clamping plates 141 and the two reciprocating clamping plates 142 completely cross and coincide. The side of the reciprocating clamping plate 142 away from the blanking fork 22 extends out of the side of the two fixed clamping plates 141 close to the axis of the rotating frame 13. After the limiting post 232 is no longer restricted, under the action of the elastic force of the spring, it is pushed upward, and the side on the circumferential outer surface of the limiting post 232 fits with the side of the connecting block away from the blanking fork 22. Thus, when blanking, the wire is stably fixed inside the clamping assembly 14 through the moving part 23.

[0053] The process of cutting the wire:

[0054] When the wire fixing is completed, the blanking fork 22 is located at the periphery of the rotating disk. The lifting plate 165 on the outer surface of the blanking fork 22 is below the connecting rod 164. The blanking fork 22 moves upward inside the moving seat 21 through the arc groove, so that the upper surface of the blanking fork 22 fits against the bottom end of the wire coiling cylinder, and the wire coiling cylinder is slightly lifted upward. At the same time, the lifting plate 165 moves upward with the blanking fork 22 and fits against the bottom of the connecting rod 164, driving the connecting rod 164 to move upward. Among them, the lifting plate 165 adopts a bifurcated design, and the distance between the forks inside it is greater than the thickness of the wire dividing block 15, facilitating the lifting plate 165 to extend to the outer surface of the wire dividing block 15 and support the lower surface of the connecting rod 164 protruding outside.

[0055] During the upward movement of the blanking fork 22, the connecting rod 164 is fixedly connected to the lifting plate 163 and moves upward inside the wire dividing block 15 following the upward lifting of the blanking fork 22. During the movement, the inclined surface of the lifting plate 163 is in close contact with the inclined surface of the cutting plate 161, pushing the cutting plate 161 towards the axis of the rotating frame 13. The tension spring 162 is compressed and elastically deformed, and the cutting edge on the outside of the cutting plate 161 gradually protrudes from the wire dividing hole 151 and moves towards the direction of the wire in a taut state inside the wire dividing hole 151. After the blanking fork 22 lifts the coiling cylinder, the connecting rod 164 and the lifting plate 163 also reach the highest point within their formation range. The cutting edge of the cutting plate 161 completely passes through the wire dividing hole 151 and is close to the inner wall surface of the sliding groove. The cutting plate 161 completely cuts off the wire during this process to facilitate the smooth blanking of the wire coiling cylinder.

[0056] The process of blanking the wire coiling cylinder:

[0057] After the cutting part 16 cuts off the wire, the driving unit inside the driving cavity drives the wire coiling cylinder to rotate several circles, so that the remaining wire inside the wire coiling cylinder is retracted from the other wire dividing parts. The rotating disk at the bottom shrinks downward, and the gravity of the wire coiling cylinder is completely on the blanking fork 22. The moving seat 21 retracts in the electric slide rail inside the base in the direction away from the rotating frame 13, completing the synchronous blanking action of multiple drums on one side.

[0058] After the blanking fork 22 follows the moving seat 21 and returns to the initial position, the connecting rod 164 is no longer supported by the lifting plate 165. Under the action of the tension spring 162, the cutting plate 161 is pushed towards the connecting rod 164, making the cutting plate 161 hidden inside the wire dividing block 15 again. The cutting plate 161 is at the position closest to the connecting rod 164 within this stroke range. Under the action of its own gravity and the push from below the cutting plate 161, the lifting plate 163 is at the lowest point within this stroke range and returns to the initial state, hiding the cutting plate 161 to avoid harm to the staff or other wires.

[0059] The driving unit starts, driving the rotating plate 12 and the rotating frame 13 to continue rotating by ninety degrees, so that the next placement cavity 131 is in the same position, and the above steps are repeated for the wire reel in this placement cavity 131 for the blanking operation. The feeding equipment can be correspondingly placed above the base, and the feeding equipment and the blanking part 2 are symmetrically distributed on the left and right sides of the rotating frame 13. While blanking is carried out on one side, the feeding action is completed on the other side. When the feeding of the reel in the placement cavity 131 in the rotating frame 13 is completed, the new reel is unsealed, and the wire end is found and passed through each wire dividing part in the placement cavity 131 and reaches the wire dividing block 15 and passes through the wire dividing hole 151. At this time, the clamping assembly 14 still clamps the wire remaining from the previous time. Since there is a certain distance between the reciprocating clamping plate 142 and the wire dividing block 15, there is still a certain distance left for the remaining wire, which is convenient for joining with the wire in the new wire reel. After the joining is completed, the tension adjusting part in the driving cavity is started, so that the two batches of wires are both in a tensioned state. Then, by pressing the limit post 232, the spring inside it is compressed, and the reciprocating clamping plate 142 is moved in the direction away from the fixed clamping plate 141 under the guidance of the card slot, realizing the separation action between the two, and the outer surface of the connecting plate 143 is attracted to the magnetic plate 144, and the wire is no longer subject to the clamping action and can continue the stranding work of the cable.

[0060] During this process, the equipment has the following advantages:

[0061] Advantage 1: Automatic control is adopted, and multiple wire reels on one side can be blanked synchronously, improving the blanking efficiency, reducing the time loss of blanking for a single reel, meeting the requirements of mass production, helping to improve the overall production efficiency, and reducing the complexity and error probability of manual intervention.

[0062] Advantage 2: By using the action of inserting the blanking fork 22 in the blanking part 2 into the interior of the placement cavity 131, the connecting plate 143 is pushed before blanking, driving the reciprocating clamping plate 142 to move towards the fixed clamping plate 141, and then the two are cross-distributed. The outer end of the reciprocating clamping plate 142 near the wire threading hole 121 penetrates outside the fixed clamping plate 141, and the hole formed by the reciprocating clamping plate 142 and the arc-shaped groove in the fixed clamping plate 141 becomes smaller, fixing the wire. The clamping assembly 14 can ensure the stability of the cable that has been partially stranded between the rotating plate 12 and the outer end stranding die, avoiding the occurrence of situations such as the loosening and deformation of this part of the cable. After completing the loading operation of the new coil cylinder, the new and old wires are joined near the wire dividing block 15. At this time, the clamping assembly 14 divides the wire into two parts, new and old wires. Among them, the new wire covers the interval from the start of the coil cylinder to the joint, and the old wire extends from the joint to the outer end stranding die. Then, the tension of the new wire is finely restored by means of the tension adjusting member. In this way, when the clamping assembly 14 is released, the new wire can achieve a seamless and smooth transition with the old wire, ensuring the coherence and stability of the wire connection process, effectively avoiding various problems caused by sudden changes in tension or poor connection. After the clamping assembly 14 is released, the tension system can quickly return to a stable state, so that the tension is stable during the stranding process of the new coil, ensuring the tightness and uniformity of the stranding, and improving the quality of the cable product.

[0063] Advantage 3: There is a certain gap between the clamping assembly 14 and the wire dividing block 15, which can leave a certain distance for the wire while the fixed clamping plate 141 and the reciprocating clamping plate 142 clamp the previous wire, facilitating the connection with the new wire, simplifying the wire connection process, reducing the search and adjustment of the manual connection position, and improving the coherence and efficiency of production.

[0064] Advantage 4: The fixed clamping plate 141 and the reciprocating clamping plate 142 are cross-distributed, greatly increasing the friction force. At the same time, the use of the internal rubber block 145 and the groove increases the friction force and can adapt to the shape of the wire, ensuring that the wire is stably fixed, preventing the wire from sliding or falling off during subsequent operations, improving the reliability of the operation. The groove is designed perpendicular to the end face of the rotating plate 12, which can effectively avoid the situation where the wire rotates inside the fixed clamping plate 141 and the reciprocating clamping plate 142 due to the residual stranding force, reducing the occurrence of situations such as the loosening and deformation of the wire that has been partially stranded between the rotating plate 12 and the outer end stranding die.

[0065] Advantage 5: Except when the cutting plate 161 enters the wire dividing hole 151 during blanking and cuts the wire, the cutting plate 161 is automatically hidden inside the wire dividing block 15 at other times, avoiding damage to the staff or the wire during normal work, ensuring the integrity of the wire, being beneficial to subsequent stranding and use, improving the product quality, and ensuring the safety of production.
