Abstract
Description
Technical Field
[0001] This invention relates to the field of wire coil shaping technology, specifically to a wire coil shaping device. Background Technology
[0002] Wire coils are an important raw material form in metal processing, construction materials, and other fields. Their regularity directly affects the efficiency and quality of subsequent unwinding and processing. Early wire coil shaping was limited by production scale and technical conditions, and mostly relied on simple mechanical fixing methods. The development of simple mechanical fixing methods was due to two main reasons: firstly, early wire production was small and specifications were limited, so simple mechanical fixing could complete basic coil shaping based on experience; secondly, simple mechanical fixing equipment was simple in structure and low in cost, and clamping in one direction could meet the low standards of coil regularity required at the time, making it widely used in small and medium-scale production scenarios. However, with the development of large-scale and diversified wire production, simple mechanical fixing can only achieve rigid clamping in one direction and cannot provide all-round constraint on the coil. The coil is subjected to uneven forces in the radial and circumferential directions, and the internal wire is prone to gaps and wrinkles. Moreover, there is a lack of effective vibration and repositioning mechanism, and loose wire is difficult to align naturally. In order to improve the regularity, it is necessary to add a secondary sorting step of simple mechanical fixing, which increases labor costs and makes it difficult to guarantee the stability of the shaping quality. Summary of the Invention
[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a wire coiling shaping device that solves the problems of simple mechanical fixing only achieving rigid clamping in one direction, failing to provide all-round constraint on the coil, uneven stress in the radial and circumferential directions, easy formation of gaps and wrinkles in the internal wire, lack of an effective vibration return mechanism, and difficulty in naturally aligning loose wire. To improve regularity, a secondary straightening step of simple mechanical fixing is necessary, which increases labor costs and makes it difficult to guarantee the stability of shaping quality.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a shaping device for wire coiling, which has the following advantages: 1. This wire coil forming device, through the combined effects of internal and external fixation, vibration positioning, and flexible protection, achieves the following during the wire coil forming process: a hydraulic cylinder drives a rectangular fixing plate and contact plate for clamping and positioning; a dual-axis cylinder drives a support rod to achieve internal and external fixation with the fixing plate, forming a circumferential constraint on the coil. This ensures uniform force on the coil in both radial and circumferential directions, guaranteeing neat coil forming and effectively avoiding problems such as tangled coils and misalignment. This significantly improves subsequent wire release efficiency. A vibration motor drives a vibrating plate and the wire coil to vibrate synchronously, while a push plate and rubber pad provide flexible support. This achieves a comprehensive effect of precise positioning, stable internal and external fixation, and vibration positioning of the wire coil. Compared to traditional methods that rely solely on simple mechanical fixing, this device can adapt to the forming needs of wire coils of different specifications, ensuring natural alignment of the wire inside the coil, eliminating gaps and wrinkles, preventing local loosening or deformation, and improving the neatness of the wire coil and its adaptability to subsequent processing.
[0013] 2. The wire coil shaping device has a rectangular groove on the vibrating plate that provides positioning space for the wire coil placement rack, ensuring that the wire coil is located in the preset position on the opposite side of the two contact plates during each shaping. The four auxiliary rods on the lower surface of the push plate slide in cooperation with the vibrating plate, providing vertical guidance for the push plate to rise and fall, preventing the push plate from shifting during the wire coiling process, ensuring that the push plate always remains horizontal, and ensuring that the wire coil rises and falls smoothly and that the center point is precisely aligned with the fixed clamp and support rod.
[0014] 3. The wire coiling shaping device uses an auxiliary spring between the contact plate and the rectangular fixing plate to adjust the position of the contact plate through elastic extension and contraction during the shaping process. When the wire coil undergoes slight deformation due to vibration, it avoids damage to the wire surface caused by rigid contact. The arc-shaped rubber pad on the push plate makes flexible contact with the lower surface of the wire coil. The rectangular rubber pad on the opposite side of the fixing plate enhances the friction with the outer wall of the coil, ensuring both support and fixing stability, and preventing the wire from being scratched or slipping during vibration or clamping, thus ensuring the surface quality of the wire.
[0015] 4. The wire coiling shaping device uses a vibrating plate connected to a fixed base plate via four high-strength auxiliary vibration springs. The springs act as buffers and amplify the amplitude during vibration. Meanwhile, the internal auxiliary telescopic rods ensure that the vibrating plate vibrates only in the vertical direction, avoiding horizontal displacement that could affect the shaping accuracy. The vibration generated by the vibration motor is transmitted to the wire coiling through the vibrating plate, causing the loose wire inside to naturally return to its original position under the vibration. Compared with a single fixed or vibrating structure, this device can ensure both the vibration shaping effect and the overall structural vibration stability, preventing component displacement and damage.

[0018] 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.
[0019] Please see Figure 1-7 This invention provides a new technical solution: a wire coiling shaping device, including a fixed base plate 1. The fixed base plate 1 is the basic bearing component of the device. A shaping component is provided on the fixed base plate 1. Four high-strength auxiliary vibration springs 3 are fixedly connected to the upper surface of the fixed base plate 1. Two cylinders 16 are fixedly connected to the lower surface of the fixed base plate 1. The fixed base plate 1 provides stable support for the entire device, ensuring accurate installation of each component. The upper surface provides the installation foundation for the vibration structure, and the cylinders 16 on the lower surface provide power support for the lifting and lowering of the push plate 13.
[0020] High-strength auxiliary vibration spring 3: The high-strength auxiliary vibration spring 3 plays a role in buffering and amplifying the amplitude during vibration. It connects the fixed base plate 1 and the vibrating plate 14 to ensure that the vibration can be effectively transmitted to the wire coil. At the same time, it absorbs the vibration impact through elastic deformation and protects the structure of the device.
[0021] Vibratory plate 14: The lower surface of the vibratory plate 14 has four auxiliary rods 15 slidingly passing through its lower end. The vibratory plate 14 is the core carrier for vibration transmission and installation of the moving component. The rectangular slide groove 17 provides sliding guidance for the moving plate 5. The vibration motor 2 on the lower surface provides the vibration source. The hydraulic cylinder 4 provides power for the clamping structure and provides a through channel for the cylinder extension end and the auxiliary rods 15.
[0022] Auxiliary telescopic rods: The upper ends of the four auxiliary telescopic rods are fixedly connected to the lower surface of the vibrating plate 14. The auxiliary telescopic rods limit the vibration direction of the vibrating plate 14, ensuring that it vibrates only in the vertical direction, avoiding horizontal displacement from affecting the shaping accuracy, and enhancing the stability of the vibration structure.
[0023] Vibration motor 2: Four vibration motors 2 are fixedly connected to the lower surface of the vibrating plate 14. The vibration motor 2 is the vibration source of the device. When working, it generates vibration and transmits it to the vibrating plate 14, which in turn drives the wire coil to vibrate synchronously, so that the loose wire inside naturally returns to its position under the action of vibration, eliminating gaps and wrinkles in the coil.
[0024] Hydraulic cylinder 4: Hydraulic cylinder 4 provides power for the movement of the clamping structure. Through the extension and retraction of the telescopic end, it drives the connecting plate 6, the moving plate 5 and the L-shaped moving plate 7 to move, so as to realize the initial positioning and clamping of the wire coil by the rectangular fixing plate 9.
[0025] Connecting plate 6: Connecting plate 6 is the connecting medium between hydraulic cylinder 4 and moving plate 5. It transmits the power of hydraulic cylinder 4 to moving plate 5, realizes the conversion and transmission of power direction, and ensures that moving plate 5 moves synchronously with the extension and retraction of hydraulic cylinder.
[0026] Movable plate 5: Two movable plates 5 are slidably connected to the inner walls of two rectangular slide grooves 17 respectively. An L-shaped movable plate 7 is fixedly connected to the upper surface of each of the two movable plates 5. The movable plates 5 slide along the rectangular slide grooves 17, driving the L-shaped movable plate 7 and the rectangular fixed plate 9 above to move synchronously, thereby realizing the left and right position adjustment of the clamping structure and adapting to different specifications of wire coils.
[0027] L-shaped moving plate 7: The L-shaped moving plate 7 connects the rectangular fixed plate 9 and the moving plate 5, transmits the power of the moving plate 5 to the rectangular fixed plate 9, and provides a stable mounting platform for the dual-axis cylinder 8, ensuring that the dual-axis cylinder 8 does not shake when it is working.
[0028] Rectangular fixing plate 9: Rectangular grooves 10 are provided on the upper surfaces of the two rectangular fixing plates 9 and the two contact plates 19. The rectangular fixing plates 9 provide the mounting base for the contact plates 19, guide rods 11 and the actuators of the dual-axis cylinder 8. The rectangular through grooves 20 provide sliding channels for the slider 21 and the fixing clamp 12. The rectangular grooves 10 provide positioning space for the wire coil placement rack.
[0029] Contact plate 19: The opposing surfaces of the two contact plates 19 are fixedly connected to one end of the eight auxiliary springs 23. The contact plates 19 directly contact the coiled wire. Flexible contact is achieved through the elastic extension and contraction of the auxiliary springs 23 to avoid rigid collision damage to the surface of the wire. At the same time, the rectangular fixing plate 9 is used to achieve the initial clamping of the coiled wire.
[0030] Guide rod 11: The outer walls of the eight guide rods 11 are all slidably sleeved with auxiliary springs 23. The guide rods 11 guide the movement of the contact plate 19, prevent the contact plate 19 from shifting under the action of the auxiliary springs 23, and ensure that the contact plate 19 always maintains parallel contact with the wire coil.
[0031] Auxiliary springs 23: Eight auxiliary springs 23 are slidably sleeved on the outer wall of eight guide rods 11 respectively. The front and rear ends of the eight auxiliary springs 23 are fixedly connected to the corresponding contact plates 19 and rectangular fixing plates 9 respectively. The auxiliary springs 23 adaptively adjust the position of the contact plates 19 through elastic extension and contraction. When the wire coil undergoes slight deformation due to vibration, it avoids damage to the wire surface caused by rigid contact, and at the same time enhances the fit between the contact plates 19 and the wire coil.
[0032] Rectangular through slot 20: The rectangular through slot 20 provides a sliding guide channel for the slider 21 and the fixed clamping plate 12, ensuring that the actuator driven by the dual-axis cylinder 8 can move smoothly in the horizontal direction and achieve precise fixation of the wire coil.
[0033] Dual-axis cylinder 8: Dual-axis cylinder 8 provides power for the inner and outer fixing components. The front dual-axis cylinder 8 drives the support rod 18 to support the inner wall of the wire coil, and the rear dual-axis cylinder 8 drives the fixing clamp 12 to clamp the outer wall of the wire coil.
[0034] Rectangular connecting fixing plate 22: The rectangular connecting fixing plate 22 connects the dual-axis cylinder 8 and the slider 21, transmits the power of the dual-axis cylinder 8 to the slider 21, drives the support rod 18 to move synchronously, and ensures that the support rod 18 moves smoothly.
[0035] Slider 21: The rear surfaces of both sliders 21 are fixedly connected to support rods 18. The sliders 21 slide along the rectangular through groove 20 to guide the support rods 18, ensuring that the support rods 18 can be accurately inserted into the inside of the wire coil and move radially to achieve stable support.
[0036] Support rod 18: Support rod 18 is used to support the inner wall of the wire coil. Driven by the dual-axis cylinder 8, it supports from the inside to the outside and forms a ring-shaped constraint with the outer fixed clamp 12, so that the coil is subjected to uniform force in the radial and circumferential directions.
[0037] Fixed clamp 12: Fixed clamp 12 is used to fix the outer wall of the wire coil. Driven by the dual-axis cylinder 8, it is squeezed from the outside to the inside. With the help of the support rod 18, the wire coil is clamped inside and out. The rectangular rubber pad enhances the friction and prevents the wire from slipping when vibrating.
[0038] Rectangular rubber pads: Rectangular rubber pads are set on the opposite sides of the two fixed clamping plates 12. The rectangular rubber pads enhance the friction between the fixed clamping plates 12 and the outer wall of the wire coil, preventing the wire coil from slipping during vibration shaping. At the same time, they play a flexible buffering role, avoiding excessive clamping force that could damage the wire surface.
[0039] Cylinder 16: Cylinder 16 provides power for the lifting and lowering of push plate 13. Through the extension and retraction of the telescopic end, push plate 13 is driven to lift or lower the wire coil, realizing the separation of wire coil from the placement rack and position adjustment.
[0040] Push plate 13: The upper surface of push plate 13 is provided with an arc-shaped rubber pad, and the lower surface of push plate 13 is fixedly connected with four auxiliary rods 15. Push plate 13 is used to lift the wire coil and raise and lower it to the height corresponding to the fixed clamp plate 12 and the support rod 18. The arc-shaped rubber pad achieves flexible contact with the lower surface of the wire coil to avoid scratching the wire.
[0041] Curved rubber pad: The curved rubber pad is set on the upper surface of the push plate 13. The curved rubber pad is in flexible contact with the lower surface of the wire coil, which not only ensures the stability of the support, but also buffers the impact force during vibration, prevents the bottom of the wire coil from being scratched, and protects the surface quality of the wire.
[0042] Auxiliary rod 15: The auxiliary rod 15 provides vertical guidance for the lifting and lowering of the push plate 13, preventing the push plate 13 from deviating during the wire coiling process, ensuring that the push plate 13 always remains horizontal, and ensuring smooth lifting and lowering of the wire coiling.
[0043] Rectangular groove 10: The rectangular groove 10 provides positioning space for the wire coil placement rack, ensuring that the wire coil is located at the preset position on the opposite side of the two contact plates 19 during each shaping, thereby improving the repeatability and accuracy of the shaping operation.
[0044] Wire coil placement rack: The wire coil placement rack is set on the inner wall of four rectangular slots 10. The wire coil placement rack is concave in shape, and the front surface of the wire coil placement rack has a concave groove. The wire coil placement rack is used to carry wire coils that are to be shaped and those that have already been shaped. The concave groove plays a preliminary positioning role for the wire coils, which facilitates the feeding and unloading of the coils by the external conveying components.
[0045] Furthermore, when using the wire coil shaping device, the wire coil placement rack carrying the wire coil is first moved above the vibrating plate 14 by the external conveying assembly, and the external conveying assembly is turned off when the wire coil is located on the opposite side of the two contact plates 19. Subsequently, two hydraulic cylinders 4 are activated. The telescopic ends of the two hydraulic cylinders 4 retract through the connecting plate 6, the moving plate 5, and the L-shaped moving plate 7. The rear dual-axis cylinder 8 drives the two rectangular fixed plates 9 to move to the relative position, so that the two contact plates 19 contact the wire coil. At the same time, the two fixed clamping plates 12 and the two support rods 18 move synchronously. The two fixed clamping plates 12 are located on the left and right sides of the wire coil, and the two support rods 18 are located on the inner side of the wire coil. Then, the two cylinders 16 are activated, and the telescopic ends of the two cylinders 16 push the push plate 13 to move upward. The push plate 13 pushes the wire coil to move upward. When the two fixed clamps 12 and the two support rods 18 are aligned with the center point of the wire coil, the two cylinders 16 are closed. At this time, the wire coil does not contact the wire coil placement rack. Then, two hydraulic cylinders 4 are activated again, which drive two rectangular fixing plates 9 to further clamp the wire coil. Then, two dual-axis cylinders 8 are activated. The dual-axis cylinder 8 located on the front side drives two support rods 18 to move to opposite positions to support the inner wall of the wire coil. The dual-axis cylinder 8 located on the rear side drives two fixing plates 12 to move to opposite positions to clamp the outer wall of the wire coil. Among them, two support rods 18 support from the inside out and two fixed clamps 12 squeeze from the outside in, forming a ring-shaped constraint on the coil, so that the coil is subjected to uniform force in both radial and circumferential directions, ensuring that the coil is shaped and regular, effectively avoiding problems of tangled coils and misalignment, and significantly improving the efficiency of subsequent wire laying. After the wire coil is fixed inside and out, the four vibration motors 2 on the lower surface of the vibrating plate 14 are started. The vibration motors 2 generate vibration and transmit it to the vibrating plate 14. The vibrating plate 14 is connected to the fixed base plate 1 through four high-strength auxiliary vibration springs 3. The high-strength auxiliary vibration springs 3 play a role in buffering and amplifying the amplitude during vibration. At the same time, the auxiliary telescopic rod inside ensures that the vibrating plate 14 vibrates only in the vertical direction, avoiding horizontal displacement from affecting the shaping accuracy. The vibration is transmitted through the vibrating plate 14 to the L-shaped moving plate 7, the rectangular fixed plate 9 and the contact plate 19, thereby driving the wire coil to vibrate synchronously, so that the loose wire inside the wire coil naturally returns to its position under the action of vibration, eliminating gaps and wrinkles in the coil. During the vibration shaping process, when the wire coil undergoes slight deformation due to vibration, the auxiliary spring 23 adaptively adjusts the position of the contact plate 19 through elastic extension and contraction to avoid damage to the wire surface caused by rigid contact. The eight guide rods 11 guide the movement of the contact plate 19 to prevent it from shifting. The arc-shaped rubber pad on the upper surface of the push plate 13 makes flexible contact with the lower surface of the wire coil, ensuring the stability of the support and preventing the bottom of the wire coil from being scratched during vibration. The rectangular rubber pad on the opposite side of the fixing clamp 12 enhances the friction with the outer wall of the wire coil, preventing the wire coil from sliding during vibration and ensuring the shaping effect. According to the material and regularity requirements of the wire coil, the working time of the vibration motor 2 is set. After the preset time is reached, the vibration motor is turned off. After the vibrating plate 14 is completely still, the two dual-axis cylinders 8 are started in reverse. The dual-axis cylinder 8 on the front side drives the two support rods 18 to move to the opposite position and detach from the inner wall of the wire coil. The dual-axis cylinder 8 on the rear side drives the two fixed clamps 12 to move to opposite positions and loosen the outer wall of the wire coil. Then, the two hydraulic cylinders 4 are started in reverse, driving the two rectangular fixed plates 9 to move to opposite positions and the contact plate 19 separates from the wire coil. Then, the two cylinders 16 are started in reverse. The telescopic ends of the two cylinders 16 drive the push plate 13 to move down, and the wire coil falls down and is placed back in the concave groove of the wire coil placement rack. Finally, the shaped wire coil and placement rack are moved out of the shaped area by the external conveying component, completing one shaped operation. In the process of wire coiling and shaping, the hydraulic cylinder 4 drives the rectangular fixing plate 9 and the contact plate 19 to clamp and position the coil, and the dual-axis cylinder 8 drives the support rod 18 and the fixing clamp 12 to achieve internal and external fixation, forming a ring-shaped constraint on the coil. This ensures that the coil is subjected to uniform force in both the radial and circumferential directions, ensuring that the coil is shaped neatly and effectively avoiding problems such as tangled coils and misalignment. This significantly improves the efficiency of subsequent wire feeding. The vibration motor 2 drives the vibrating plate 14 and the wire coil to vibrate synchronously, and the push plate 13 and the rubber pad provide flexible support. This achieves a comprehensive effect of precise positioning of the wire coil, stable internal and external fixation, and vibration-based positioning. Compared with the traditional method that only relies on simple mechanical fixing and shaping, this method can adapt to the shaping needs of wire coils of different specifications, ensure that the wire inside the coil is naturally positioned, eliminate gaps and wrinkles, avoid local loosening or deformation, and improve the neatness of the wire coil and its adaptability to subsequent processing. The rectangular groove 10 on the vibrating plate 14 provides positioning space for the wire coil placement rack, ensuring that the wire coil is located at the preset position on the opposite side of the two contact plates 19 during each shaping. The four auxiliary rods 15 on the lower surface of the push plate 13 slide with the vibrating plate 14, providing vertical guidance for the lifting and lowering of the push plate 13, preventing the push plate 13 from shifting during the pushing of the wire coil, ensuring that the push plate 13 always remains horizontal, and ensuring that the lifting and lowering of the wire coil is smooth and that the center point is precisely aligned with the fixed clamping plate 12 and the support rod 18. During the shaping process, the auxiliary spring 23 between the contact plate 19 and the rectangular fixing plate 9 adjusts the position of the contact plate 19 by elastic extension and contraction. When the wire coil undergoes slight deformation due to vibration, rigid contact is avoided to prevent damage to the wire surface. The arc-shaped rubber pad on the push plate 13 makes flexible contact with the lower surface of the wire coil. The rectangular rubber pad on the opposite side of the fixing clamp 12 enhances the friction with the outer wall of the coil, ensuring both support and fixing stability, and preventing the wire from being scratched or slipping during vibration or clamping, thus ensuring the surface quality of the wire. The vibrating plate 14 is connected to the fixed base plate 1 through four high-strength auxiliary vibration springs 3. The springs 3 play a role in buffering and amplifying the amplitude during vibration. At the same time, the auxiliary telescopic rod inside ensures that the vibrating plate 14 vibrates only in the vertical direction, avoiding horizontal displacement that affects the shaping accuracy. The vibration generated by the vibration motor 2 is transmitted to the wire coil through the vibrating plate 14, so that the loose wire inside naturally returns to its position under the action of vibration. Compared with a single fixed or vibrating structure, it can not only ensure the vibration shaping effect, but also ensure the overall structural vibration stability and avoid component displacement and damage.
[0046] Example: Application of curved anti-slip struts replacing original strut 18 in the shaping of fine diameter wire coils. When a certain electronic wire processing plant was processing fine-diameter wire coils, the original support rod 18 was a straight rod structure, which had a small contact area with the inner wall of the wire coil. The fine-diameter wire was relatively soft, and the local pressure concentration of the straight rod support rod could easily cause the wire to deform. Moreover, during the forming vibration, the friction between the straight rod and the inner wall was insufficient, which could easily lead to relative slippage and failure to form stable support. As a result, after the coil was formed, there were still local loose and disordered coil problems, which affected the accuracy of subsequent wire laying. At this time, the original support rod 18 was replaced with an arc-shaped anti-slip support rod. The installation dimensions were completely consistent with the original parts. The side of the support rod that contacts the wire was designed with an arc shape, and the surface was added with anti-slip texture. The arc design increases the contact area between the strut and the inner wall of the coiled fine-diameter wire, dispersing local pressure and preventing deformation of the soft wire due to pressure concentration, thus ensuring the original roundness of the wire. The anti-slip texture on the surface enhances the friction between the strut and the wire during vibration, preventing relative slippage and forming stable inner support. This solves the problems of deformation and unstable support of fine-diameter wire caused by the small contact area and insufficient friction of traditional straight struts, and meets the core needs of non-damaging support and stable shaping of coiled fine-diameter soft wire. The arc-shaped structure can adaptively conform to the curvature of the inner wall of the wire coil, ensuring that the support force is evenly distributed on the inner side of the coil. It forms a more precise circumferential constraint with the outer fixing clamp 12, so that the coil is subjected to balanced radial force. When vibrating and returning to position, the loose wire inside can be arranged more smoothly and naturally. In coordination with the power output of the dual-axis cylinder 8, the arc-shaped support rod is subjected to more stable force, avoiding support offset caused by local slippage, further improving the circumferential regularity of the coil. In coordination with the vibration of the vibration motor 2, the stable support makes the vibration energy evenly transmitted to the entire coil, eliminating local looseness and wrinkles, and improving the consistency of shaping. The installation shaft diameter and length of the arc-shaped anti-slip support rod are exactly the same as the original support rod 18. It can be directly fixed to the slider 21 without modifying the structure of the dual-axis cylinder 8, rectangular through groove 20, etc. The overall thickness of the support rod is equivalent to that of the original part, which does not affect the fit gap with the inner wall of the wire coil or the clamping space of the fixing clamp 12. The anti-slip texture is made of wear-resistant material, and its service life is equivalent to that of the original support rod. During maintenance, only the support rod needs to be replaced. The operation process is the same as that of the original part, and it can be quickly adapted to the existing fine diameter wire coiling and shaping production line.
