[0002] In the metal products processing industry, CNC milling machines are commonly used processing equipment, capable of precisely milling metal raw materials to meet diverse product requirements. However, most existing CNC milling machines still rely on manual loading for raw material preparation, a method with numerous drawbacks. Firstly, manual loading is inefficient and unsuitable for large-scale production. Secondly, manual operation is prone to errors, leading to inaccurate loading, affecting product processing precision, and potentially causing safety accidents. While some automatic loading devices exist, existing ones are complex in structure, costly, and lack close integration with CNC milling machines, failing to achieve efficient and precise automated production. Utility Model Content

[0003] This utility model aims to at least partially solve one of the problems in related technologies. Therefore, one of the objectives of this utility model is to provide an automatic feeding mechanism for metal product raw materials, used to achieve efficient and precise conveying of raw materials from the feed cylinder to the CNC milling machine worktable.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] like Figure 1 - Figure 4 As shown, the automatic feeding mechanism 1 for metal product raw materials provided in this application includes:

[0030] Support frame 10;

[0031] The material conveying cylinder 20 is mounted on the support frame 10. The inside of the material conveying cylinder 20 is used to hold metal product raw materials, and its raw material outlet corresponds to the worktable of the CNC milling machine 2.

[0032] The material conveying drive assembly 30 includes a drive member 31, a connecting rod 32, and a pusher plate 33. The pusher plate 33 is disposed inside the material conveying cylinder 20. One end of the connecting rod 32 is connected to the drive end of the drive member 31, and the other end is connected to the pusher plate 33.

[0033] A basic and crucial feeding system framework is constructed through the combination of support frame 10, feeding cylinder 20, and feeding drive assembly 30. In short, this framework design eliminates the complex multi-component structure of traditional automatic feeding devices, laying the foundation for efficient and precise feeding. Specifically, support frame 10 provides stable support for the entire mechanism, ensuring stable operation of feeding cylinder 20 and feeding drive assembly 30; feeding cylinder 20 is used to hold metal product raw materials, and its raw material outlet is designed to correspond to the worktable of CNC milling machine 2, allowing the raw material to be directly transported to the processing position, reducing intermediate transmission links; the drive component 31 in feeding drive assembly 30 drives the pusher plate 33 to move within feeding cylinder 20 via connecting rod 32, thereby pushing the raw material towards the outlet and realizing automatic material feeding. The rationale is that existing feeding devices suffer from complex structures and high costs, while by simplifying the structure, automatic feeding is achieved using only necessary components, reducing the number of parts and assembly complexity, thereby lowering equipment manufacturing and maintenance costs, while also improving feeding efficiency and reliability.

[0034] Furthermore, the bottom of the support frame 10 is provided with adjustable anchor bolts.

[0035] As the foundation of the mechanism, the stability of the support frame 10 is crucial, and the adjustable anchor bolts further optimize its performance. Specifically, when the anchor bolts are adjustable, they can be adjusted according to different installation ground conditions to keep the support frame 10 level, thereby ensuring the accurate tilt angle of the conveying cylinder 20 and guaranteeing smooth material transport within it. Whether the ground is slightly uneven or the installation location is different, the adjustable anchor bolts can adapt, enhancing the equipment's environmental adaptability. The rationale is that in actual installation, the ground may be uneven. If the support frame 10 cannot be adjusted, the tilt angle of the conveying cylinder 20 will change, affecting material transport. The adjustable anchor bolt design effectively solves this problem, improving the convenience of equipment installation and operational stability.

[0036] Furthermore, the feed cylinder 20 is inclined, with the relatively higher end being the raw material inlet and the relatively lower end being the raw material outlet.

[0037] The inclined design of the feed cylinder 20 is a crucial design element for achieving automated raw material conveying. Together with the supporting frame 10 and anchor bolts, it forms a more complete feeding mechanism. Specifically, with the feed cylinder 20 inclined, the raw material tends to slide downwards under gravity. Combined with the pushing action of the feeding drive component 30, it can move more efficiently towards the outlet, reducing the energy consumption of the drive component. Simultaneously, the design with the high end as the raw material inlet and the low end as the raw material outlet, with the outlet corresponding to the worktable, ensures that the raw material, after entering from the inlet, directly reaches the worktable under the action of gravity and thrust, shortening the conveying path and improving feeding efficiency. The rationale behind this analysis is that gravity, as a natural force, can reduce energy consumption and improve the economy of conveying when used rationally. This inclined design and outlet position conform to the mechanical principles of raw material conveying, ensuring that the raw material reaches the processing position quickly and accurately, meeting the needs of automated production.

[0038] Furthermore, the inner wall of the feed cylinder 20 is provided with a wear-resistant lining.

[0039] During long-term use, the conveyor cylinder 20 will experience wear due to the transport of raw materials. The wear-resistant lining is a protective measure for the conveyor cylinder 20, enabling it to maintain good working condition for a longer period. Specifically, when metal raw materials are transported inside the conveyor cylinder 20, friction occurs with the cylinder wall, especially with long, thin metal materials, which may cause significant wear. The wear-resistant lining effectively resists this friction, reducing the wear of the conveyor cylinder 20, extending its service life, and lowering maintenance and replacement costs. The rationale is that wear of equipment components is a common problem in actual production, and the application of wear-resistant materials can significantly improve the durability of components. Therefore, the wear-resistant lining on the inner wall of the conveyor cylinder 20 meets the durability requirements of industrial production, ensuring the long-term stable operation of the automatic feeding mechanism.

[0040] Furthermore, the feed cylinder 20 has a feed inlet 21 at the top near the raw material inlet, and the feed cylinder 20 is also provided with a flip cover 23, which is rotatably connected to one side edge of the feed inlet 21.

[0041] The placement of the feed inlet 21 and the flip cover 23 enhances the raw material feeding function of the conveying cylinder 20, further improving the operational convenience and equipment protection of the entire feeding mechanism. Specifically, the feed inlet 21 is located near the top of the raw material inlet of the conveying cylinder 20, facilitating the placement of metal products into the cylinder by operators. This ergonomic design makes operation more convenient. The rotating connection design of the flip cover 23 allows the feed inlet 21 to be closed when no raw materials are being fed, preventing dust and debris from entering. It also reduces dust leakage during raw material transport, maintaining a clean working environment and improving equipment safety. The rationale is that in industrial production, operational convenience and environmental protection are crucial factors. The placement of the feed inlet 21 facilitates manual material feeding, while the flip cover 23 meets the needs for dust prevention and safety, making the feeding mechanism design more rational and complete.

[0042] Furthermore, the driving component 31 is a drive motor or a cylinder.

[0043] As the power source for the material conveying drive assembly 30, the choice of drive component 31 significantly impacts the performance and applicable scenarios of the entire feeding mechanism. Offering both a drive motor and a cylinder increases the adaptability and flexibility of the equipment. Specifically, the drive motor features stable power output and high control precision, making it suitable for applications requiring high conveying speed and position control. It can precisely control the movement of the pusher plate 33, thereby accurately controlling the conveying speed and position of the raw materials and ensuring accurate delivery to the CNC milling machine 2 worktable. The cylinder, on the other hand, offers advantages such as fast response, simple maintenance, and lower cost, making it more suitable for production scenarios where control precision requirements are not particularly high but rapid response is necessary. The rationale is that different production scenarios have different power source requirements. Providing multiple drive component options allows the automatic feeding mechanism to be configured according to actual production needs, improving the equipment's versatility, meeting the requirements of different users and production conditions, and further reducing operating costs.

[0044] Furthermore, the shape of the pusher plate 33 is adapted to the inner wall of the feed cylinder 20.

[0045] As the component that directly pushes the raw material, the fit between the pusher plate 33 and the inner wall of the conveying cylinder 20 is one of the key factors in ensuring smooth material conveying. This design makes the conveying drive assembly 30 more efficient and reliable. Specifically, when the shape of the pusher plate 33 is adapted to the inner wall of the conveying cylinder 20, the pusher plate 33 can fit against the cylinder wall to the maximum extent when moving inside the conveying cylinder 20, reducing the possibility of the raw material getting stuck in the gap between the pusher plate 33 and the cylinder wall, and ensuring that the raw material can be pushed smoothly. At the same time, this adapted shape also allows the pushing force of the pusher plate 33 to be evenly distributed on the raw material, avoiding tilting or deformation of the raw material due to uneven force, thereby improving the stability and accuracy of raw material conveying. The analysis is based on the fact that in mechanical transmission, the fit between components directly affects the transmission efficiency and working effect. The adaptation design of the pusher plate 33 and the inner wall of the conveying cylinder 20 conforms to the basic principles of mechanical design, can effectively solve the problem of jamming in the raw material conveying process, improve the working efficiency and reliability of the feeding mechanism, and ensure the smooth operation of the automatic feeding process.

[0046] Furthermore, such as Figure 4 As shown, the surface of the pusher plate 33 is covered with an elastic buffer layer.

[0047] The elastic buffer layer on the surface of the pusher plate 33 is a protective measure for the quality of raw materials and the operating condition of the equipment, enabling the feeding mechanism to better protect the raw materials and equipment while ensuring conveying efficiency. Specifically, for metal raw materials, especially those with high surface quality requirements, if the pusher plate 33 has a hard surface, it may cause scratches or indentations when pushed by the pusher plate 33. The elastic buffer layer acts as a buffer when the pusher plate 33 comes into contact with the raw material, reducing the direct hard impact of the pusher plate 33 on the raw material, thereby protecting the surface quality of the raw material and preventing damage during the feeding process. At the same time, the elastic buffer layer can also absorb some of the impact energy during the movement of the pusher plate 33, reducing noise and vibration during equipment operation, making the entire feeding mechanism run more smoothly. The rationale is that in industrial production, protecting the surface integrity of some high-precision or high-surface-quality metal raw materials is crucial. The design of the elastic buffer layer meets the needs of raw material protection, while also improving the comfort and stability of equipment operation, reducing equipment wear caused by impact and vibration, and extending the service life of the equipment.

[0048] Furthermore, such as Figure 4 As shown, the surface of the pusher plate 33 is provided with a spiral groove adapted to the raw material of the metal product.

[0049] The spiral grooves on the surface of the pusher plate 33 are an optimized design for raw material conveying, enabling the feeding mechanism to convey long strip metal raw materials more accurately and stably, meeting higher production requirements. Specifically, when the surface of the pusher plate 33 has spiral grooves adapted to the metal raw material, the long strip metal raw material will embed itself into the spiral grooves during the pushing process. This not only increases the friction between the pusher plate 33 and the raw material, preventing the raw material from slipping during the pushing process, but also guides and positions the raw material through the shape of the spiral grooves, allowing the raw material to move along a specific path within the conveying cylinder 20, thereby more accurately controlling the conveying position and posture of the raw material. Especially for processing scenarios that require conveying in a specific direction or have high positioning requirements, this spiral groove design can significantly improve the feeding accuracy. The analysis is based on the fact that the spiral structure has a guiding and transmission function in mechanical transmission. Applying it to the cooperation between the surface of the pusher plate 33 and the metal raw material can utilize the characteristics of the spiral to achieve precise control of the raw material, meeting the needs of high-precision processing and production. It solves the problems of easy slippage and inaccurate positioning during raw material conveying in existing technologies, improving the processing accuracy and production efficiency of the product.

[0050] This utility model also proposes a CNC milling machine 2, which includes a CNC milling machine body and an automatic feeding mechanism for metal products. The specific structure of the automatic feeding mechanism for metal products is as described in the above embodiments. Since this CNC milling machine 2 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0051] Specifically, the main body of the CNC milling machine includes a bed, spindle box, worktable, tool system, and control system. This CNC milling machine 2, by integrating an automatic feeding mechanism, achieves a fully automated process from raw material feeding to machining completion, eliminating the need for manual raw material feeding operations. This significantly reduces manual intervention, lowers labor intensity, and avoids potential errors associated with manual feeding, improving machining stability and reliability. The automatic feeding mechanism works closely with the worktable, control system, and other components of the CNC milling machine 2. The control system coordinates the operation of the automatic feeding mechanism and all components of the CNC milling machine 2, achieving seamless integration of automatic feeding and machining processes, thus improving production efficiency. The analysis is based on the fact that existing CNC milling machines 2 rely on manual feeding, resulting in low efficiency and poor accuracy. However, by integrating the automatic feeding mechanism, utilizing its high efficiency and precision feeding characteristics, combined with the high-precision machining capabilities of the CNC milling machine 2, a complete automated machining system is formed, meeting the needs of large-scale, high-precision production, and demonstrating significant technological advancement and practical value.
