Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a continuous wire feeding mechanism for processing compression springs. Background Technology

[0002] In the field of mechanical engineering, springs are an indispensable basic component of various mechanical equipment and have extremely wide applications in many industries such as automobiles, aerospace, and electronic equipment. As an important type of spring, the processing accuracy and efficiency of compression springs play a key role in ensuring the overall performance of products and production efficiency. Therefore, a continuous wire feeding mechanism for compression spring processing is particularly needed.

[0003] However, in existing compression spring wire feeding mechanisms, the conductor plate usually needs to be installed above the wire feeding groove. However, due to the limitations of its structural design, it is difficult to achieve stable installation of the conductor plate in this position, which seriously affects the wire feeding accuracy and stability. In addition, traditional compression spring wire feeding mechanisms are mostly rigidly fixedly connected to the spring processing device. Once the equipment fails, the entire wire feeding mechanism must be removed during maintenance, which is extremely inconvenient and greatly reduces production and maintenance efficiency. Utility Model Content

In addition, the traditional spring wire feeding mechanism is mostly rigidly fixedly connected to the spring processing device. Once the equipment fails, the entire wire feeding mechanism must be removed during maintenance, which is extremely inconvenient and greatly reduces the efficiency of production and maintenance.

The wire feeding groove is fixedly connected to the upper surface of the height fine-tuning plate. The first engaging groove is fixedly connected to the upper surface of the wire feeding groove. A second engaging limit is fixedly connected to the upper surface of the device. A threaded rod is rotatably connected to one side surface of the wire feeding groove. A knob is fixedly connected to one side surface of the threaded rod. A bearing is fixedly connected to one side surface of the threaded rod.

[0007] Preferably, two sets of electric push rods are symmetrically arranged on the upper central surface of the height fine-tuning plate, and one set of telescopic sleeves is arranged at each of the four corners of the height fine-tuning plate.

[0008] Preferably, the wire feeding groove is connected to the height fine-tuning plate by means of an electric push rod and a telescopic sleeve, and the first engaging groove is located on the central axis symmetrical plane at the end of the wire feeding groove away from the working surface.

[0009] Preferably, two sets of the second engagement groove are provided on the central axis surface of the wire feeding groove. One set is located at the center of the wire feeding groove, and the other set is symmetrical to the first engagement groove through the second engagement groove of the first set.

[0010] Preferably, a set of telescopic blocks is provided at each of the four corners of the wire feeding groove, and their positions correspond to the positions of the telescopic sleeve. The first engaging limit and the second engaging limit are engaged and connected with the first engaging groove and the second engaging groove.

[0011] Preferably, the threaded rod, knob, and bearing are provided in one set in each section of the wire feeding groove, for a total of six sets. The displacement motor housing is slidably connected in the sections separated by the wire feeding groove by the rotation of the threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This continuous wire feeding mechanism for compression spring processing, through the setting of the wire feeding mechanism, allows for the setting of relevant parameters via the operation panel. The electric push rod extends and retracts according to the command. Due to its cooperation with the telescopic sleeve, it drives the wire feeding groove to slide up and down on the height fine-tuning plate, thereby precisely adjusting the height position of the wire feeding groove to adapt to different processing requirements or to better connect with other components. Subsequently, the first and second locking grooves are respectively engaged with the first and second locking limits to achieve locking connection. Then, the steel wire is placed above the first and second locking grooves to limit the steel wire and ensure stable wire feeding during the wire feeding process. Then, the knob is rotated, and the knob drives the limiting groove through the displacement motor housing to clamp the steel wire. Finally, the micro motor works, driving the rotating disk to rotate. The rotating disk and the clamping disk work together to apply driving force to the steel wire in the wire feeding groove, so that it is stably fed towards the wire exit hole at the set speed and direction. Finally, the steel wire enters the shearing and winding module through the wire exit hole for the subsequent compression spring winding process. This setting allows the conductor plate to be installed stably at this position, improving the wire feeding accuracy and stability. In addition, traditional compression spring wire feeding mechanisms are mostly connected to the spring processing device in a modular way. If the equipment fails, only the faulty area needs to be repaired or replaced, improving production and maintenance efficiency. Attached Figure Description

[0021] Please see Figure 1-5 This utility model provides a technical solution: a continuous wire feeding mechanism for spring processing, including a base 1, a feeding groove 2 on the upper surface of the base 1, a connecting column 3 fixedly connected to one side surface of the base 1, an operation panel 4 fixedly connected to one side surface of the connecting column 3, a working surface 5 fixedly connected to the upper surface of the base 1, a wire outlet hole 6 on the upper surface of the working surface 5, a shearing and winding module 7 fixedly connected to one side surface of the working surface 5, a lifting block 8 fixedly connected to the upper surface of the base 1, and a wire feeding mechanism 9 provided on the upper surface of the lifting block 8;

[0022] The wire feeding mechanism 9 includes a support plate 901, a height fine-tuning plate 902, an electric push rod 903, a telescopic sleeve 904, a wire feeding groove 905, a first engaging groove 906, a second engaging groove 907, a telescopic block 908, a first engaging limit 909, a second engaging limit 910, a threaded rod 911, a knob 912, a bearing 913, a displacement motor housing 914, a spring 915, a connecting tongue 916, a connecting disc 917, a micro motor 918, an engaging disc 919, a rotating disc 920, and a limiting groove 921. The support plate 901 is fixedly connected to the upper surface of the lifting block 8. The height fine-tuning plate 902 is fixedly connected to the upper surface of the support plate 901. The electric push rod 903 is fixedly connected to the upper surface of the height fine-tuning plate 902. The height fine-tuning plate 904... A telescopic sleeve 904 is fixedly connected to one side surface of the height adjustment plate 902. A wire feeding groove 905 is fixedly connected to the upper surface of the height adjustment plate 902. A first engaging groove 906 is fixedly connected to the upper surface of the wire feeding groove 905. A second engaging limit 910 is fixedly connected to the upper surface of the wire feeding groove 905. A threaded rod 911 is rotatably connected to one side surface of the wire feeding groove 905. A knob 912 is fixedly connected to one side surface of the threaded rod 911. A bearing 913 is fixedly connected to one side surface of the threaded rod 911. A displacement motor housing 914 is fixedly connected to one side surface of the bearing 913. A spring 915 is fixedly connected to the inner surface of the displacement motor housing 914. A connecting tongue 916 is slidably connected to the upper surface of the displacement motor housing 914. The upper surface of the connecting tongue 916... A connecting disc 917 is fixedly connected to the surface of the device. A micro motor 918 is fixedly connected to the upper surface of the connecting disc 917. A locking disc 919 is fixedly connected to the upper surface of the connecting disc 917. A rotating disc 920 is fixedly connected to the upper surface of the micro motor 918. A limiting groove 921 engages with the upper surface of the connecting disc 917. The device is connected via a support plate 901, a height fine-tuning plate 902, an electric push rod 903, a telescopic sleeve 904, a wire feeding groove 905, a first locking groove 906, a second locking groove 907, a telescopic block 908, a first locking limit 909, a second locking limit 910, a threaded rod 911, a knob 912, a bearing 913, a displacement motor housing 914, a spring 915, a connecting tongue 916, a connecting disc 917, and a micro motor 918. The motor 918, locking disc 919, rotating disc 920, and limiting groove 921 are configured so that, during use, relevant parameters are set on the operation panel 4, and the electric push rod 903 extends and retracts according to the command. Due to its cooperation with the telescopic sleeve 904, it drives the wire feeding groove 905 to slide up and down on the height fine-tuning plate 902, thereby precisely adjusting the height position of the wire feeding groove 905 to adapt to different processing requirements or to better connect with other components. Subsequently, the first locking groove 906 and the second locking groove 907 are respectively engaged with the first locking limit 909 and the second locking limit 910 to lock and connect. Then, the steel wire is placed above the first locking groove 906 and the second locking groove 907 to limit the steel wire and ensure stable wire feeding during the wire feeding process.Then, rotating knob 912 causes the displacement motor housing 914 to drive the limiting groove 921 to clamp the steel wire. Finally, the micro motor 918 operates, driving the rotating disk 920 to rotate. The rotating disk 920, in conjunction with the clamping disk 919, applies a driving force to the steel wire in the wire feeding groove 905, ensuring it is stably fed towards the wire exit hole 6 at a set speed and direction. Ultimately, the steel wire enters the shearing and winding module 7 through the wire exit hole 6 for subsequent spring winding processing. This design allows the conductor plate to be stably installed at this position, improving wire feeding accuracy and stability. Furthermore, traditional spring wire feeding mechanisms are often connected to the spring processing device in a modular manner. If the equipment malfunctions, maintenance only requires repairing or replacing the affected area, improving production and maintenance efficiency.

[0023] Furthermore, two sets of electric push rods 903 are symmetrically arranged on the upper central surface of the height fine-tuning plate 902, and one set of telescopic sleeves 904 are arranged at each of the four corners of the height fine-tuning plate 902. With the arrangement of the electric push rods 903, during use, the two sets of electric push rods 903 are symmetrically arranged on the upper central surface of the height fine-tuning plate 902, which can apply a uniform force to the height fine-tuning plate 902 during the extension and retraction process, avoiding tilting or imbalance caused by single-point force application. The telescopic sleeves 904 at the four corners further assist in support and guidance, making the displacement of each point of the height fine-tuning plate 902 more synchronized when it moves up and down, thereby ensuring the stability of the wire feeding groove during the height adjustment process.

[0024] Furthermore, the wire feeding trough 905, through the setting of the electric push rod 903 and the telescopic sleeve 904, forms an up-and-down sliding connection with the height fine-tuning plate 902. The first engaging groove 906 is set on the central axis symmetrical plane at the end of the wire feeding trough 905 away from the working surface 5. Through the setting of the height fine-tuning plate 902, the electric push rod 903, the telescopic sleeve 904 and the wire feeding trough 905, during use, the height position of the wire feeding trough 905 can be precisely adjusted according to different compression spring processing requirements, such as the different requirements of different specifications of compression springs for the wire feeding height. This ensures that the wire can enter the subsequent processing steps at the optimal height, improves processing accuracy and product quality, ensures the smoothness of the wire during the conveying process, and reduces problems such as wire jamming or wear caused by height mismatch.

[0025] Furthermore, two sets of second locking grooves 907 are provided on the central axis surface of the wire feeding groove 905. One set is located at the center of the wire feeding groove 905, and the other set is symmetrical to the first locking groove 906 through the second locking groove 907 of the first set. Through the setting of the second locking grooves 907, in use, the two sets of second locking grooves 907 cooperate with the first locking groove 906 to limit the wire multiple times, effectively preventing the wire from moving left and right or shaking in the wire feeding groove 905, so that the wire maintains a more stable state during the conveying process and reduces the possibility of jamming or collision with other components caused by wire deviation.

[0026] Furthermore, a set of telescopic blocks 908 is provided at each of the four corners of the wire feeding trough 905, and their positions correspond to the positions of the telescopic sleeve 904. The first engaging limit 909 and the second engaging limit 910 are engaged with the first engaging groove 906 and the second engaging groove 907. Through the setting of telescopic blocks 908 and telescopic sleeve 904, in use, the corresponding telescopic blocks are engaged with the telescopic grooves to fix the wire feeding trough from multiple directions, restricting the horizontal displacement of the wire feeding trough, making the wire feeding trough more stable during height adjustment and wire feeding, reducing shaking, and thus ensuring the stability of wire conveying.

[0027] Furthermore, each section of the wire feeding trough 905 has one set of threaded rod 911, knob 912, and bearing 913, for a total of six sets. The displacement motor housing 914 slides within the sections of the wire feeding trough 905 through the rotation of the threaded rod 911. The use of the threaded rod 911, knob 912, and bearing 913 provides a modular design for each section of the wire feeding trough. During equipment maintenance, personnel can repair or replace components in specific sections without requiring large-scale disassembly and repair of the entire wire feeding system, reducing maintenance difficulty and cost, and improving equipment maintainability and management efficiency.

[0028] Furthermore, multiple anti-slip textures are formed on one side surface of the knob 912. The displacement motor housing 914 is slidably connected to the connecting tongue 916 on the horizontal surface through the setting of the spring 915. With the setting of the knob 912, the anti-slip texture can effectively prevent accidental operation due to hand slippage during use, reduce the possibility of equipment failure or safety accidents caused by accidental operation, and improve the safety of equipment operation. Moreover, this sliding connection method allows the displacement motor housing to adaptively adjust its position within a certain range according to the actual working conditions, ensuring the smoothness and stability of wire feeding.

[0029] Working Principle: This continuous wire feeding mechanism for spring processing, through the setting of the wire feeding mechanism 9, allows for the setting of relevant parameters via the operation panel 4. The electric push rod 903 extends and retracts according to the command. Due to its cooperation with the telescopic sleeve 904, it drives the wire feeding groove 905 to slide up and down on the height fine-tuning plate 902, thereby precisely adjusting the height position of the wire feeding groove 905 to adapt to different processing requirements or better connect with other components. Subsequently, the first engaging groove 906 and the second engaging groove 907 cooperate with the first engaging limit 909 and the second engaging limit 910 respectively to achieve engagement connection. Then, the steel wire is placed above the first engaging groove 906 and the second engaging groove 907 to limit the steel wire and ensure stable wire feeding during the process. Finally, the knob 912 is rotated, and the knob 912 drives the displacement motor housing 914 to... The moving limit groove 921 clamps the steel wire. Finally, the micro motor 918 works, driving the rotating disk 920 to rotate. The rotating disk 920 and the clamping disk 919 work together to apply driving force to the steel wire in the wire feeding groove 905, so that it is stably fed towards the wire outlet hole 6 at a set speed and direction. Finally, the steel wire enters the shearing and winding module 7 through the wire outlet hole 6 for the subsequent compression spring winding process. This setting allows the conductor plate to be installed stably at this position, improving the wire feeding accuracy and stability. In addition, traditional compression spring wire feeding mechanisms are mostly connected to the spring processing device in a modular way. If the equipment fails, only the faulty area needs to be repaired and replaced, improving production and maintenance efficiency. The electric push rod 903 is model XYDHA24-800, and the micro motor 918 is model WL-37RS528.
