Description

Technical Field

[0001] This invention relates to the field of hardware processing technology, and in particular to a hardware product processing equipment. Background Technology

[0002] Currently, in the hardware processing industry, when trimming the edges of metal products such as bowls and cups, it is usually necessary to trim the edges to achieve a smooth and even finish. Commonly used trimming equipment has a relatively simple structure, typically employing a fixed or manually adjustable cutting mechanism to cut the rotating workpiece. However, in practical use, it has been found that when the cutting speed is too high, it not only easily damages the cutting blade, affecting its lifespan, but also leads to uneven edges, excessive burrs, and other problems, thus reducing the processing quality of the product. Furthermore, existing trimming equipment has limited functionality and lacks an effective control and adjustment mechanism for the cutting process, making it difficult to meet the high-efficiency, high-quality trimming requirements of hardware products of different specifications. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a hardware product processing equipment that can improve the quality of edge cutting.

[0004] According to the present invention, a hardware product processing equipment includes a machine base, a rotating device, and a cutting device. The rotating device is disposed on the machine base and is used to fix the position of the hardware product and drive the hardware product to rotate. The cutting device includes a first frame, a first sliding seat, a pushing mechanism, and a cutting blade. The first frame is disposed on the machine base, and the first sliding seat is slidably connected to the first frame. A roller is rotatably disposed on the first sliding seat. The cutting blade is fixedly installed on the first sliding seat. The pushing mechanism includes a pushing plate and a first driving structure. The first driving structure is connected to the pushing plate and drives the pushing plate to move in a direction perpendicular to the sliding direction of the first sliding seat. The pushing plate is provided with an inclined groove that cooperates with the roller. The extending direction of the inclined groove is inclined to the moving direction of the pushing plate. When the pushing plate moves, it can force the roller to move along the inclined groove, thereby driving the first sliding seat to move so that the cutting blade approaches or moves away from the edge of the hardware product.

[0005] The hardware processing equipment according to the above embodiments of the present invention has at least the following beneficial effects: The hardware processing equipment provided in this invention uses a rotating device to drive the hardware product to rotate, and in conjunction with a cutting device having a roller and a slanted groove structure, achieves stable and controllable movement of the cutting blade, allowing the cutting blade to accurately approach or move away from the edge of the hardware product. It can be understood that the rotating device fixes the hardware product and drives it to rotate at a uniform speed, providing a stable processing reference for the cutting operation. This ensures that the workpiece edge is always in a continuous movement state during the cutting process, which is beneficial for the cutting blade to cut evenly along the circumferential direction and avoids excessive local force affecting the cutting quality. The roller and the slanted groove on the push plate cooperate to form a mechanical linkage structure. When the push plate is pushed by the first drive mechanism, due to the inclination angle of the slanted groove, the roller is forced to slide along the slanted groove, thereby driving the sliding seat to slide along the first frame. This converts the linear motion of the push plate into a controllable displacement of the sliding seat, allowing the cutting blade to slowly and smoothly approach or move away from the edge of the workpiece. Furthermore, the inclination angle of the sloping groove determines the speed and amplitude of the sliding seat movement. By rationally designing the sloping groove angle, the feed speed of the cutting blade can be controlled, avoiding damage to the cutting blade or uneven cutting edges due to excessive feed. Simultaneously, the roller and sloping groove use a rolling contact method, reducing frictional resistance, improving transmission efficiency, and ensuring smooth movement. On the other hand, by controlling the action parameters (such as speed and stroke) of the first drive mechanism, precise adjustment of the cutting blade feed amount and feed speed can be achieved, adapting to the cutting requirements of hardware products of different materials, thicknesses, or shapes. In summary, this embodiment of the invention, through the linkage structure of the roller and sloping groove, combined with a controllable propulsion mechanism and a rotating device, effectively achieves smooth feeding and precise control of the cutting blade, not only improving cutting quality and efficiency but also extending the service life of the cutting blade, demonstrating promising prospects for industrial applications.

[0021] Reference Figures 1 to 7According to the present invention, a hardware product processing equipment includes a machine base 100, a rotating device, and a cutting device. The rotating device is mounted on the machine base 100 and is used to fix the position of the hardware product 900 and drive the hardware product 900 to rotate. The cutting device includes a first frame 310, a first sliding seat 320, a pushing mechanism, and a cutting blade 330. The first frame 310 is mounted on the machine base 100, the first sliding seat 320 is slidably connected to the first frame 310, and a roller 340 is rotatably mounted on the first sliding seat 320. The cutting blade 330 is fixedly mounted on the first frame 100. On a sliding seat 320, the pushing mechanism includes a pushing plate 350 and a first driving structure. The first driving structure is connected to the pushing plate 350 and drives the pushing plate 350 to move in a direction perpendicular to the sliding direction of the first sliding seat 320. The pushing plate 350 is provided with a groove 351 that cooperates with the roller 340. The extension direction of the groove 351 is inclined to the moving direction of the pushing plate 350. When the pushing plate 350 moves, it can force the roller 340 to move along the groove 351, thereby driving the first sliding seat 320 to move so that the cutting blade 330 is close to or away from the edge of the hardware product 900.

[0022] It is understood that the hardware processing equipment provided in this embodiment of the invention drives the hardware product 900 to rotate through a rotating device, and in conjunction with a cutting device having a roller 340 and a slanted groove 351 structure, achieves stable and controllable movement of the cutting blade 330, enabling the cutting blade 330 to accurately approach or move away from the edge of the hardware product 900. It is also understood that the rotating device fixes the hardware product 900 and drives it to rotate at a uniform speed, providing a stable processing reference for the cutting operation. This ensures that the workpiece edge is always in a continuous motion state during the cutting process, which is beneficial for the cutting blade 330 to cut evenly along the circumferential direction and avoids excessive local stress that could affect the cutting quality. The roller 340 and the inclined groove 351 on the push plate 350 cooperate to form a mechanical linkage structure. When the push plate 350 is pushed by the first drive mechanism, due to the inclination angle of the inclined groove 351, the roller 340 is forced to slide along the inclined groove 351, which in turn drives the sliding seat to slide along the first frame 310. This converts the linear motion of the push plate 350 into the controllable displacement of the sliding seat, allowing the cutting blade 330 to slowly and smoothly approach or move away from the edge of the workpiece. Furthermore, the inclination angle of the inclined groove 351 determines the speed and amplitude of the sliding seat's movement. By reasonably designing the inclination angle of the inclined groove 351, the feed speed of the cutting blade 330 can be controlled, avoiding damage to the cutting blade or uneven cutting edges due to excessive feed. At the same time, the roller 340 and the inclined groove 351 adopt a rolling contact method, which reduces frictional resistance, improves transmission efficiency, and ensures the smoothness of movement. On the other hand, by controlling the motion parameters (such as speed and stroke) of the first drive mechanism, the feed amount and feed speed of the cutting blade 330 can be precisely adjusted to adapt to the cutting requirements of hardware products 900 with different materials, thicknesses, or shapes. In summary, the embodiments of the present invention, through the linkage structure of the roller 340 and the inclined groove 351, combined with the controllable propulsion mechanism and the rotation device, effectively achieve stable feeding and precise control of the cutting blade 330, which not only improves the cutting quality and efficiency but also extends the service life of the cutting blade, and has good prospects for industrial application.

[0023] It should be noted that the inventors have discovered through experiments that there is a direct relationship between the inclination angle of the slant 351 and the feed speed of the cutting blade 330. Specifically, the smaller the inclination angle of the slant 351, the slower the feed speed of the cutting blade 330; conversely, the larger the inclination angle of the slant 351, the faster the feed speed of the cutting blade 330. When the push plate 350 moves forward in its direction of movement, the roller 340 moves along the slant 351. If the inclination angle of the slant 351 is small, then for every unit length the push plate 350 moves, the vertical displacement of the roller 340 within the slant 351 (i.e., the distance the sliding seat and the cutting blade 330 move closer to or further away from the edge of the hardware product 900) will be smaller. Therefore, the feed speed of the cutting blade 330 will be relatively slow, which helps to achieve a more precise and smooth cutting operation, improves the cutting quality, and reduces the risk of blade damage, making it suitable for scenarios with high requirements for edge processing quality. Conversely, a larger sloping groove 351 tilt angle means that for the same travel distance of the feed plate 350, the roller 340 will have a larger vertical displacement, causing the cutting blade 330 to approach or move away from the workpiece more quickly, thereby speeding up the feed rate. This is more suitable for rough machining or scenarios where the material hardness is low and excess parts need to be removed quickly.

[0024] Furthermore, refer to Figure 3 According to some embodiments of the present invention, the angle between the centerline of the inclined groove 351 along the length direction and the centerline of the propulsion plate 350 along the length direction is α, and satisfies: 5°≤α≤15°.

[0025] Understandably, the inventors have concluded through experiments that the inclination range of the aforementioned slant groove 351 can ensure that the cutting blade 330 has a certain feed speed while effectively slowing down the feed rate, avoiding problems such as blade wear or uneven cutting caused by excessive feed, thus balancing processing efficiency and cutting quality, and is the preferred range for achieving cutting stability.

[0026] Preferably, according to some embodiments of the present invention, the angle between the centerline of the inclined groove 351 along the length direction and the centerline of the propulsion plate 350 along the length direction is α, and satisfies: α = 8°. However, it is not limited to this, and other angles that satisfy the above-mentioned inclination angle range can be used according to the actual situation, which will not be elaborated here.

[0027] Understandably, the inventors determined through experiments that the angle of the aforementioned inclined groove 351, as the optimal angle, is an ideal value obtained after comprehensively considering the cutting speed, cutter life, cutting quality, and equipment operational stability. This angle ensures a smooth and controllable cutting process, allowing the cutting blade 330 to have a relatively uniform speed distribution when approaching the workpiece, reducing vibration and impact caused by speed changes, and further improving the stability and consistency of the cutting process, without excessively reducing processing efficiency. It is suitable for cutting operations on most conventional hardware products 900 and has wide applicability.

[0028] Furthermore, refer to Figure 1 and Figure 5 According to some embodiments of the present invention, the rotating device includes a turntable 210, an inner liner 220, a second drive structure 290, and a pressing mechanism. The turntable 210 is rotatably mounted on the machine base 100. The inner liner 220 is fixedly connected to the turntable 210. The outer diameter of the inner liner 220 is adapted to the inner diameter of the hardware product 900. The hardware product 900 is fitted downwards into the inner liner 220. The second drive structure 290 is connected to the turntable 210 and is used to drive the turntable 210 to rotate. The pressing mechanism is mounted on the machine base 100 and is used to press the hardware product 900 down onto the inner liner 220.

[0029] Understandably, the rotatable turntable 210, in conjunction with the inner liner 220, provides stable clamping of the metal product 900, ensuring uniform force and continuous rotation of the workpiece during the cutting process. The second drive structure 290 provides stable power output, guaranteeing smooth and controllable rotation; the pressing mechanism further enhances the stability of the workpiece during processing, preventing uneven cutting or damage to the cutting tool due to vibration or displacement. The overall structure improves the equipment's adaptability to different specifications of metal products 900 and its cutting accuracy.

[0030] Furthermore, refer to Figures 1 to 4 According to some embodiments of the present invention, a first frame 310 is arranged on one side of a turntable 210, one side of a first sliding seat 320 is slidably connected to the side of the first frame 310 near the turntable 210, and a roller 340 is rotatably provided on the other side of the first sliding seat 320. An extension arm 321 extending toward the inner liner 220 is provided at the bottom of the first sliding seat 320. A cutting blade 330 is fixedly installed at the end of the extension arm 321 and located directly below the edge of the hardware product 900. The first driving structure includes a first telescopic cylinder 360, which is fixedly installed on the first frame 310 and located on the side of the first sliding seat 320. The end of the telescopic rod of the first telescopic cylinder 360 is fixedly connected to a push plate 350. The inclined groove 351 is inclined downward along the forward direction of the push plate 350 (i.e., the extension direction of the telescopic rod of the first telescopic cylinder 360).

[0031] Understandably, the aforementioned structural layout is reasonable, enabling the cutting blade 330 to precisely act directly below the edge of the metal product 900, improving cutting efficiency and edge quality. The inclined groove 351 design of the feed plate 350, in conjunction with the roller 340, achieves smooth displacement control of the first sliding seat 320, ensuring that the cutting blade 330 slowly and steadily approaches or moves away from the workpiece, effectively avoiding damage to the cutting blade 300 or poor edge cutting caused by excessive feed. Furthermore, the cylinder-driven method offers rapid response and flexible control, making it suitable for automated operation.

[0032] Furthermore, refer to Figure 2 and Figure 4 According to some embodiments of the present invention, the propulsion mechanism further includes two guide plates 370 symmetrically arranged on both sides of the first sliding seat 320. The guide plates 370 are fixedly connected to the first frame 310. The guide plates 370 are provided with guide grooves 371, and the propulsion plate 350 passes through the two guide grooves 371 in sequence.

[0033] Understandably, the guide plate 370 and guide groove 371 provide excellent guiding support for the push plate 350, ensuring its straightness and stability during movement and preventing deviation or swaying from affecting the cutting accuracy. The symmetrical arrangement also enhances the structure's balance and resistance to eccentric loads, thereby improving the reliability and service life of the equipment.

[0034] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the edge trimming device further includes a first feeding mechanism, which includes a first guide rail 380 and a third drive structure 390. The first guide rail 380 is fixedly mounted on the machine base 100. A first slider 311 is fixedly connected to the bottom of the first frame 310. The first slider 311 is slidably connected to the first guide rail 380. The third drive structure 390 is connected to the first frame 310 and can drive the first frame 310 to move along the first guide rail 380 so that the edge trimming blade 330 moves to directly below or away from the edge of the metal product 900.

[0035] Understandably, the first feed mechanism enables the entire trimming device to move precisely in the horizontal direction, facilitating the quick and accurate positioning of the trimming blade 330 to the processing position. It also allows for rapid retraction after processing, improving work efficiency. The guide rail and slider's cooperative structure ensures smooth operation, facilitating integration with an automated control system and enhancing the equipment's versatility and flexibility. Specifically, the worker places the metal product 900, which needs to be trimmed, into the inner liner 220, then starts the rotating device, the pressing mechanism starts and presses the metal product 900 onto the inner liner 220. Then, the second drive structure 290 drives the turntable 210 to rotate, thereby rotating the metal product 900. Subsequently, the first feed mechanism starts to drive the first frame 310 to move and drive the trimming blade 330 to directly below the edge of the metal product 900. Immediately afterwards, the first drive structure starts to drive the push plate 350 forward, and through the cooperation of the inclined groove 351 and the roller 340, drives the first sliding seat 320 to move upward so that the trimming blade 330 slowly and smoothly approaches the edge of the metal product 900, thereby performing the trimming work.

[0036] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the trimming device further includes a first adjustment mechanism, which includes a first base 410, a first lead screw 420, a first nut 430, and a first handwheel 440. The first base 410 is fixedly connected to the machine base 100, and a first guide rail 380 is fixedly connected to the first base 410. The first base 410 is provided with a first groove 411 extending in the same direction as the first guide rail 380. The first lead screw 420 is installed in the first groove 411, and one end of the first lead screw 420 away from the turntable 210 extends out of the first base 410 and is fixedly connected to the first handwheel 440. The first nut 430 is threadedly connected to the first lead screw 420 and fixedly connected to the bottom of the first frame 310.

[0037] Understandably, the first adjustment mechanism uses the first lead screw 420 to manually adjust and move the first frame 310 for fine-tuning, facilitating precise horizontal positioning of the cutting blade 330 to meet the cutting requirements of workpieces of different sizes. The first handwheel 440 provides intuitive and convenient operation, allowing for quick on-site adjustments and enhancing the equipment's applicability and ease of use.

[0038] Furthermore, refer to Figure 2 and Figure 4According to some embodiments of the present invention, the trimming device further includes a second adjusting mechanism, which includes a second lead screw 510, a second nut 520, a second handwheel 530, a second sliding seat 540, a connecting plate 550, and a first slide table 560. A vertical second slide groove 312 is provided on the side of the first frame 310 near the turntable 210. The second lead screw 510 is installed in the second slide groove 312, and the top end of the second lead screw 510 extends out of the first frame 310 and is fixedly connected to the second handwheel 530. The second nut 520 is threadedly engaged with the second lead screw 510. The second sliding seat 540 is fixedly connected to the first frame 310. The second slide table 313 is provided along the second slide groove 312. The second sliding seat 540 and the second slide table 313 can be slidably connected up and down. The side of the second sliding seat 540 away from the second slide groove 312 is fixedly connected to the connecting plate 550. The first telescopic cylinder 360 is fixedly installed on the connecting plate 550. The first slide table 560 and the guide plate 370 are fixedly connected to the side of the connecting plate 550 away from the second sliding seat 540. The first sliding seat 320 and the first slide table 560 can be slidably connected up and down.

[0039] Understandably, the second adjustment mechanism enables precise vertical adjustment of the trimming device, allowing the trimming blade 330 to be flexibly adjusted according to the workpiece height, adapting to hardware products 900 of different thicknesses or shapes. Simultaneously, the mating structure between the second sliding seat 540 and the second slide table 313 ensures the smoothness and repeatability of the adjustment process, contributing to improved trimming quality and equipment adaptability.

[0040] Furthermore, refer to Figure 5 According to some embodiments of the present invention, the rotating device further includes an ejection mechanism, which includes a push rod 230, an elastic element 240, and an ejection plate 250. The top of the inner liner 220 is provided with a mounting groove 221. The push rod 230 can be telescopically installed in the mounting groove 221. The bottom end of the push rod 230 is connected to the bottom wall of the mounting groove 221 through the elastic element 240. The top end of the push rod 230 extends out of the mounting groove 221 and is fixedly connected to the ejection plate 250. The diameter of the ejection plate 250 is adapted to the inner diameter of the hardware product 900.

[0041] Understandably, after the trimming operation is completed and both the trimming device and the pressing mechanism are reset, the ejector mechanism can automatically eject the workpiece through elastic reset, facilitating subsequent part removal operations and avoiding safety hazards caused by manual intervention. Simultaneously, the ejector plate 250 matches the inner diameter of the hardware product 900, effectively protecting the inner surface of the hardware product 900 from damage during processing, thus improving production efficiency and product yield.

[0042] Furthermore, refer to Figure 5According to some embodiments of the present invention, the pressing mechanism includes a hydraulic cylinder 260 and a pressure plate 270. The hydraulic cylinder 260 is fixedly installed on the machine base 100 and located directly above the turntable 210. The output rod of the hydraulic cylinder 260 faces downward and is rotatably connected to the pressure plate 270.

[0043] Understandably, the hydraulic cylinder 260 provides stable and adjustable pressure output, and the pressure plate 270 has a large contact area with the metal part 900, enabling uniform pressure application and preventing the metal part 900 from shifting or falling off during high-speed rotation. This ensures the safety and consistency of the trimming process, making it particularly suitable for high-precision or high-strength machining applications. Simultaneously, the pressure plate 270 can rotate with the metal part 900, reducing rigid contact between them during processing and effectively protecting the surface of the metal part 900 from damage, thus improving production efficiency and product yield.

[0044] Furthermore, refer to Figure 5 According to some embodiments of the present invention, the inner liner 220 has different specifications, and the bottom of the inner liner 220 is fixedly connected to a flange 280, which is detachably fixedly connected to the turntable 210 by bolts.

[0045] Understandably, the above design enhances the equipment's compatibility with various specifications of hardware products 900. Users can replace the inner liner 220 with different sizes according to actual processing needs without reconfiguring the entire rotating device, which significantly improves the equipment's versatility and ease of maintenance, and reduces operating costs.

[0046] Furthermore, refer to Figure 6 and Figure 7 According to some embodiments of the present invention, the hardware product processing equipment further includes an edge grinding device, which includes a second frame 610, a grinding disc 620, and a second feeding mechanism. The second frame 610 is disposed on the machine base 100 and located on one side of the turntable 210. The grinding disc 620 is installed on the side of the second frame 610 near the turntable 210 and is arranged at an angle. The second feeding mechanism is connected to the second frame 610 and is used to drive the second frame 610 to move so that the grinding disc 620 approaches and contacts the edge of the hardware product 900 or moves away from the hardware product 900.

[0047] Understandably, the addition of the edge grinding device enables the equipment to perform integrated edge cutting and grinding, reducing process changeover time and improving production continuity. The inclined grinding disc 620 better conforms to the edge contour of the workpiece, helping to achieve efficient and high-quality edge grinding, and improving product appearance and process quality.

[0048] Furthermore, refer to Figure 6According to some embodiments of the present invention, the second feeding mechanism includes a second guide rail 630 and a fourth driving structure 640. The second guide rail 630 is fixedly mounted on the machine base 100. A second slider 611 is fixedly connected to the bottom of the second frame 610. The second slider 611 is slidably connected to the second guide rail 630. The fourth driving structure 640 is connected to the second frame 610 and drives the second frame 610 to move along the second guide rail 630.

[0049] Understandably, the second feed mechanism ensures the stable horizontal movement of the grinding disc 620, achieving controllability and precision in the grinding process. The mating structure between the second guide rail 630 and the second slider 611 operates smoothly, facilitating integration into automated systems and enhancing the equipment's intelligence level.

[0050] Furthermore, refer to Figure 6 According to some embodiments of the present invention, the edge grinding device further includes a third adjustment mechanism, which includes a second base 710, a third lead screw 720, a third nut, and a third handwheel 730. The second base 710 is fixedly connected to the machine base 100, and the second guide rail 630 is fixedly connected to the second base 710. The second base 710 is provided with a third slide groove in the same direction as the extension of the second guide rail 630. The third lead screw 720 is installed in the third slide groove, and one end of the third lead screw 720 away from the turntable 210 extends out of the second base 710 and is fixedly connected to the third handwheel 730. The third nut is threadedly connected to the third lead screw 720 and fixedly connected to the bottom of the second frame 610.

[0051] Understandably, the third adjustment mechanism can finely adjust the grinding disc 620 in the horizontal direction to adapt to the edge position of workpieces of different sizes, ensuring the accuracy of the grinding path and improving processing precision and equipment flexibility.

[0052] Furthermore, refer to Figure 6 According to some embodiments of the present invention, the edge grinding device further includes a fourth adjustment mechanism, which includes a fourth lead screw 810, a fourth nut, a fourth handwheel 820, a third slide table 830, and a third sliding seat 840. A vertical fourth slide groove is provided on the side of the second frame 610 near the turntable 210. The fourth lead screw 810 is installed in the fourth slide groove. The top end of the fourth lead screw 810 extends out of the second frame 610 and is fixedly connected to the fourth handwheel 820. The fourth nut is threadedly connected to the fourth lead screw 810 and is fixedly connected to the third sliding seat 840. The third slide table 830 is provided on the second frame 610 along the fourth slide groove. The third sliding seat 840 and the third slide table 830 are slidably connected. The grinding disc 620 is installed on the side of the third sliding seat 840 away from the fourth slide groove.

[0053] Understandably, the fourth adjustment mechanism enables flexible vertical adjustment of the grinding disc 620, ensuring a good fit with the edge of the hardware product 900. It is suitable for grinding tasks of different heights or curved edges. The adjustment process is simple and highly accurate, which helps to improve the quality and efficiency of grinding.

[0054] Furthermore, refer to Figure 6 and Figure 7 According to some embodiments of the present invention, the edge grinding device further includes a buffer mechanism, which includes two hinged links 650 and an elastic element 240. One end of one link 650 is fixedly connected to a third sliding seat 840, and the end of the other link 650 is mounted with a grinding disc 620. The two links 650 are connected by the elastic element 240.

[0055] Understandably, the buffer mechanism can absorb the impact force caused by uneven edges or operational errors of the hardware product 900 during the edge grinding process, preventing the grinding disc 620 from directly colliding with the workpiece and causing damage. The elastic element 240 can also give the edge grinding process a certain degree of adaptability, improving the stability and safety of the equipment.

[0056] Furthermore, refer to Figure 6 and Figure 7 According to some embodiments of the present invention, the elastic element 240 includes a spring 660, both ends of the spring 660 are provided with hooks 661, and the side of the connecting rod 650 is provided with a connecting post 651, and the hooks 661 can be hooked onto the connecting post 651.

[0057] Understandably, by using spring 660 as a buffer element, the structure is simple and the response is sensitive. The connection method between hook 661 and connecting post 651 is convenient for installation and replacement. At the same time, the preload of spring 660 can be adjusted as needed to adapt to different grinding strengths and working conditions.

[0058] Furthermore, refer to Figure 6 and Figure 7 According to some embodiments of the present invention, one of the connecting rods 650 has a threaded shaft 652 at its end, and the grinding disc 620 is fitted onto the threaded shaft 652 and fixed by a locking nut 653.

[0059] Understandably, the above structure facilitates the quick replacement of grinding discs 620 with different materials or grit sizes to meet the grinding needs of different materials. At the same time, the locking nut 653 ensures that the grinding disc 620 is stable and reliable during high-speed rotation, preventing loosening and falling off, and improving operational safety and maintenance convenience.

[0060] To further explain, the edge-cutting device is used to precisely cut the edges of the hardware product 900, removing excess material; while the edge-grinding device is used to grind the cut edges, removing burrs and improving the surface finish. Both are driven by independent but coordinated mechanisms, achieving a continuous processing flow on the same machine. Compared to traditional processing, where edge cutting and grinding are usually completed step-by-step on different machines, resulting in cumbersome procedures and long processing times, this equipment integrates the edge-cutting and edge-grinding devices onto the same machine 100, allowing for completion of both operations in a single setup, significantly shortening the processing cycle and improving production efficiency. Secondly, since the two devices are located in the same working area and can automatically switch positions via guide rails, slides, and other feeding mechanisms, operators do not need to frequently change workpiece positions or manually adjust equipment parameters, thus significantly reducing labor intensity and minimizing quality issues caused by human error. Thirdly, immediate edge grinding after cutting ensures a stable and consistent edge condition, avoiding oxidation and deformation problems caused during handling or waiting that could affect subsequent grinding results. The close integration of the two processes helps improve the dimensional accuracy and surface quality consistency of the products, thereby increasing the pass rate. Fourthly, by setting an adjustable edge-cutting blade 330 and grinding disc 620 structure, as well as a matching feed and adjustment mechanism, the equipment can flexibly adjust the cutting and grinding parameters according to the different materials, thicknesses, or shapes of the hardware products 900. This design enables the equipment to meet various process requirements from roughing to finishing, and has wide applicability. Fifthly, the edge-cutting device and the edge-grinding device adopt a modular design, each with its own independent drive and adjustment system, while sharing a unified working platform. This layout not only saves installation space, but also provides a good foundation for the future introduction of automated functions such as automatic loading and unloading and multi-station linkage. Sixthly, since the edge-cutting device is responsible for the initial removal of excess material, it reduces the load on the edge-grinding device, making the friction force on the grinding disc 620 less during the grinding process, thereby extending the service life of the grinding wheel and reducing energy consumption. At the same time, staged processing also helps to control vibration and thermal deformation during processing, improving the overall stability of the machine. In summary, the coordinated operation of the edge-cutting and edge-grinding devices not only achieves efficient and high-quality edge processing of 900-type hardware products, but also enhances the functional completeness and automation potential of the equipment. This design effectively solves the problems of low efficiency and unstable quality caused by the single function and process separation of traditional equipment, providing a practical technical solution for the batch and precision processing of 900-type hardware products, and has good application value.

[0061] Furthermore, according to some embodiments of the present invention, the first telescopic cylinder 360 adopts a detachable installation structure, which can be achieved by means of bolts, buckles, or other structural methods. At the same time, the first sliding seat 320 is provided with a rotating shaft 322 for rotatably installing the roller 340, and the rotating shaft 322 can be used to detach and install the edge-rolling knife. By removing the first telescopic cylinder 360, the roller 340, and the push plate 350, and then installing the edge-rolling knife on the rotating shaft 322, the edge-rolling work of the hardware product 900 can be performed. The detachment and installation structure between the edge-rolling knife or the roller 340 and the rotating shaft 322 can be achieved by means of pins, buckles, bolts, or other structural methods, which can be determined according to the actual situation and are not specifically limited here.

[0062] Understandably, the aforementioned structural design enables the edge-cutting device to quickly replace functional components. Through simple disassembly, the original edge-cutting blade can be replaced with a curling blade, allowing the equipment to complete different processing tasks (such as edge cutting and curling) without altering the main structure, significantly improving its versatility and applicability. Utilizing the existing rotating shaft 322 on the first sliding seat 320 simultaneously achieves the rotation of the roller 340 and the installation of the curling blade, avoiding the need for a separate installation structure for the curling function, thus reducing the number of parts and the overall equipment size. This structural reuse mechanism not only reduces manufacturing costs but also facilitates equipment maintenance and management. The first telescopic cylinder 360 adopts a detachable installation method, improving the maintainability and replacement convenience of the cylinder and related components. In case of malfunction or the need for functional replacement, operators can quickly disassemble and replace components, reducing downtime and improving production efficiency. Furthermore, since the edge-cutting device supports modular replacement, various types of blade modules (such as grinding heads and stamping heads) can be further developed in the future, working in conjunction with an automatic tool changer to achieve multi-process integrated processing, providing a solid foundation for the equipment's development towards intelligence and automation. The design of the multi-functional rotating shaft 322 enables rapid switching between the edge-cutting and edge-rolling devices, effectively improving the equipment's versatility, maintainability, and adaptability. This design not only simplifies the overall structure and reduces manufacturing and maintenance costs, but also provides ample room for future functional expansion and automation upgrades, demonstrating promising industrial application prospects and significant potential for widespread adoption.

[0063] It should be noted that, in the embodiments of the present invention, each driving structure may be a cylinder, motor, hydraulic cylinder, or other similar structure, which can be determined according to the actual situation, and will not be elaborated further here. The adjusting mechanisms are not limited to the above-mentioned handwheel and ball screw pair structure, and may also be cylinders, motors, hydraulic cylinders, or other similar structures, and will not be elaborated further here.
