Abstract
Description
Technical Field
[0001] This utility model relates to a flat coil bending machine. Background Technology
[0002] In modern manufacturing, flat coils are widely used in various fields such as electronics, electrical engineering, and machinery, playing a particularly important role in equipment such as transformers, motors, and relays. Flat coils are usually made of metallic materials (such as copper and aluminum), and their shape is relatively flat and thin, making precise control of their shape during the production process crucial.
[0003] Currently, the bending of flat coils is mostly achieved using mechanical bending equipment. However, existing coil bending technology has some obvious shortcomings and technical defects in application, mainly reflected in the following aspects:
[0004] Flat coils, due to their flat shape and flexible characteristics, are prone to displacement or deformation during bending. Traditional bending machines typically fix the coil manually or using rough clamping methods, but this method cannot precisely control the coil's position and angle, resulting in unstable bending quality and potentially damaging the coil.
[0005] Existing bending machines often struggle to achieve high-precision bending, especially for flat coils requiring precise positioning. Inadequate design of the bending device or the lack of an effective positioning system can lead to inaccurate bending angles and coil position deviations, affecting product quality and performance.
[0006] Traditional coil bending equipment typically requires lengthy setup and manual operation, especially during frequent model changes or small-batch production, making rapid switchover or continuous operation difficult. Furthermore, the low level of automation and significant manual intervention in the bending process result in low overall production efficiency.
[0007] Because existing bending equipment lacks an effective control system and stability guarantee during operation, vibration and errors during the bending process can lead to uneven or unstable coil bending, further affecting production efficiency and product quality.
[0008] Existing equipment often requires a lot of manual intervention and monitoring, and is complex and labor-intensive to operate, which not only increases production costs but also increases the difficulty of operation, especially in large-scale production or high-precision applications. Utility Model Content

[0035] See Figure 1-2 As shown, a flat coil bending machine includes:
[0036] Base 1,
[0037] Coil placement slot 2 is mounted on base 1 and is used to place coils;
[0038] The coil bending groove 3 is set on the base 1 and is used to accommodate the coil bending pin;
[0039] The coil pressing device 4 is mounted on the base 1 and located above the coil placement slot 2;
[0040] The coil bending device 5 is mounted on the base 1 and located in front of the coil placement slot 2;
[0041] The coil pressing device 4 includes: lifting rods 41 disposed on both sides of the coil placement slot 2; lifting seat 42 disposed on the lifting rods 41; lifting cylinder 43 installed on the lifting seat 42 for controlling the lifting seat 42 to perform lifting operations; coil bending plate 44 disposed at the front of the lifting seat 42; and coil fixing head 45 disposed behind the coil bending plate 44.
[0042] The coil bending device 5 includes: a traveling track 51 located in front of the coil placement slot 2; a traveling track 52 located on the traveling track 51; a coil bending head 53 installed on the traveling track 52; and a pushing cylinder 54 located behind the traveling track 51 for pushing the traveling track 52 to move.
[0043] By incorporating the lifting rod 41, lifting seat 42, lifting cylinder 43, coil bending plate 44, and coil fixing head 45 in the coil pressing device 4, the coil can be precisely fixed and displacement or deformation can be prevented during bending. The synergistic effect of the lifting cylinder 43 and the coil fixing head 45 ensures the stability and positioning accuracy of the coil during processing, thereby improving the precision and consistency of the bending process.
[0044] The design of the traveling track 51 and traveling track carriage 52 in the coil bending device 5 ensures that the bending head moves precisely along the fixed track during the bending process, avoiding the error problems of traditional bending machines and providing more precise control over the bending angle and position. Whether in mass production or small-batch customized production, it can achieve high-precision bending results, greatly improving product quality.
[0045] By employing pneumatic components (such as lifting cylinder 43 and pushing cylinder 54) to control the bending process, manual intervention and operational steps are reduced. This automated design not only speeds up the clamping, pressing, and bending process of the coils, reducing operation time, but also significantly improves production efficiency, making it particularly suitable for large-scale production and production environments with rapid changeovers of multiple product types. The automated control system effectively reduces manual intervention, simplifies operation, and enhances ease of use. The use of lifting cylinder 43 and pushing cylinder 54 allows the entire equipment to automatically complete the bending process without excessive manual intervention. This not only reduces human error but also improves production safety.
[0046] Thanks to the use of stable pneumatic components and mechanical structures in its design, the entire machine operates more smoothly, reducing malfunctions caused by equipment vibration and wear. Compared to the mechanical moving parts of traditional bending equipment, the application of the pneumatic control system can effectively reduce the frequency and cost of maintenance during long-term use. The automation and precision control of the entire bending process ensure that the bending quality and accuracy of each batch of coils remain consistent. The stable movement of the bending head along the travel track 51, the precise pressing of the coil bending plate 44, and the effective positioning of the fixed pressure head all ensure a high degree of product quality consistency, meeting high product standards.
[0047] A first elastic mechanism 451 for abutting the coil fixing pressure head 45 is provided behind the coil fixing pressure head 45; the lifting cylinder 43 is connected to the lifting seat 42 through the first telescopic rod body to control the lifting of the lifting seat 42 in the vertical direction; the pushing cylinder 54 is connected to the traveling railcar 52 through the second telescopic rod body to control the forward and backward movement of the traveling railcar 52 in the horizontal direction.
[0048] The first elastic mechanism 451 is located behind the coil fixing head 45 to provide a reverse elastic force, which effectively resists the coil fixing head 45 and enhances its stability during operation. This design prevents the head from shifting or loosening due to excessive pressure or impact during operation, thereby improving the reliability of the fixing head and the accuracy of coil fixing. This design also helps ensure that the coil does not deform during bending, reducing errors and thus improving processing accuracy and consistency.
[0049] The lifting cylinder 43 is connected to the lifting seat 42 via the first telescopic rod, enabling precise control of the vertical lifting of the lifting seat 42. This structure allows the coil pressing device 4 to perform lifting actions quickly and stably, and different lifting heights can be achieved by adjusting the stroke or pressure of the cylinder to accommodate coils of different sizes and shapes. This lifting system design ensures that the coil can be precisely fixed or released before and after bending, improving the stability and precision of the processing.
[0050] The push cylinder 54 is connected to the traveling railcar 52 via the second telescopic rod, controlling the horizontal movement of the traveling railcar 52. This design can precisely control the horizontal movement path of the bending head, ensuring operational accuracy during the bending process; the use of the push cylinder 54 enables the traveling railcar 52 to move forward and backward smoothly, reducing errors or deviations caused by unstable railcar movement, thereby improving bending accuracy and adapting to the bending requirements of coils of different angles and sizes.
[0051] The design of the first elastic mechanism 451 helps to buffer pressure during bending, preventing excessive impact force from acting directly on the coil fixing head 45 and other components, thereby reducing wear and fatigue of mechanical parts and extending the service life of the equipment; at the same time, the cylinder control method can reduce the losses and failures caused by friction, jamming and other problems in traditional mechanical devices.
[0052] By controlling the vertical and horizontal movement of the lifting platform 42 and the traveling railcar 52 with cylinders, the operator only needs to set the target parameters, and the automated system can execute them accurately. This reduces the complexity and potential errors of manual operation and improves production efficiency. The implementation of automated control can reduce human error and ensure the consistency and accuracy of each bending operation, especially in mass production, it can ensure stable quality.
[0053] The coil bending plate 44 has two recessed surfaces 441 at its front end, which are used to bend the coil pins placed in the coil placement slot 2 downwards; the coil bending slot 3 is located at the position of the lifting seat 42 corresponding to the coil placement slot 2, and cooperates with the coil bending head 53 in a horizontal position.
[0054] The coil bending plate 44 has two recessed surfaces 441 at its front end, which can precisely bend the coil leads placed in the coil placement slot 2 downwards. This design ensures that the leads will not shift during the bending process, thereby achieving higher bending accuracy. The recessed surfaces 441 can evenly distribute the pressure applied to the leads, avoiding bending errors or lead damage caused by uneven pressure.
[0055] The coil bending groove 3 is located at the position of the coil placement groove 2 corresponding to the lifting seat 42, and cooperates with the coil bending head 53 in a horizontal position. This design ensures that the coil is stably fixed in the correct position during the bending process, avoiding any offset or displacement of the coil during bending. Through precise cooperation, the bending head and bending groove ensure that the bending action of each coil is consistent, reducing errors and the generation of defective products.
[0056] This design, through the combination of bending grooves and bending plates, simplifies and automates operation, improving production line efficiency. During the bending process, the coil is automatically guided to the correct position and precisely bent, reducing the need for manual intervention, minimizing errors in production, and thus improving overall work efficiency. Combined with automated equipment, it can significantly increase production speed and product consistency.
[0057] The base 1 is also provided with a vertically arranged cylinder mounting plate 11, and the lifting cylinder 43 is fixed on the cylinder mounting plate 11; the traveling railcar 52 is also provided with a limiting block 521 for abutting the coil pin, and a second elastic mechanism 522 for abutting the limiting block 521 is provided behind the limiting block 521, and the limiting block 521 is located above the coil bending head 53.
[0058] The limiting pressure block 521 is used to accurately abut the coil pin, ensuring that the coil remains in a fixed position during bending. The second elastic mechanism 522 is located behind the limiting pressure block 521 and can provide appropriate elastic pressure to ensure that the positioning of the pressure block on the pin is stable and adjustable, avoiding the offset or deformation of the coil pin during bending, and improving positioning accuracy and bending consistency.
[0059] By fixing the lifting cylinder 43 to the vertically mounted cylinder mounting plate 11, the working stability of the cylinder is enhanced. The vertical mounting method can more effectively transmit the force of the cylinder vertically to the lifting system, avoiding inaccurate lifting actions caused by cylinder tilting or instability, thereby improving the control accuracy of the entire lifting process and ensuring the accuracy and consistency of coil bending.
[0060] The limiting pressure block 521 and the second elastic mechanism 522 work together to effectively alleviate damage caused by excessive pressure while maintaining the stability of the coil leads. The elastic design of the elastic mechanism can automatically adapt to coil leads of different sizes and materials, avoiding over-clamping or damage, thus reducing the failure rate and improving production efficiency and product quality. In addition, the stable bending and positioning system reduces operator intervention, lowers the risk and human error in the production process, and further enhances production safety.
