Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window hinge manufacturing technology, and in particular to a fully automated production line for door and window hinges. Background Technology
[0002] As the core moving connector of building doors and windows, hinges directly affect the flexibility of opening and closing and the load-bearing stability of doors and windows. Modern door and window hinge production lines use metal sheets as raw materials, employing core processes such as feeding, precision cutting, multi-station stamping, CNC drilling and tapping, and automated assembly, combined with conveyor belts to achieve continuous production. The production process utilizes mold processing to ensure product dimensional accuracy, and surface treatment processes enhance rust resistance, ultimately forming standardized hinge assemblies containing hinge shafts, blades, and fixing seats, meeting the comprehensive requirements of building doors and windows for durability, load-bearing capacity, and aesthetics.
[0003] Traditional door and window hinge production lines employ a single-sided, single-machine, asymmetrical layout, making it impossible to process frame and sash hinges simultaneously. This results in low production efficiency and a large equipment footprint. The material conveying process lacks precise control via cylinder-motor linkage, leading to feeding deviations or jamming. The cutting process uses only a single cutting tool, making it difficult to handle both roughing and precision cutting of irregular shapes, resulting in poor cut surface quality and burrs. Stamping relies on step-by-step operations, unable to achieve dynamic continuous bending using multiple molds, requiring frequent machine stops for adjustments. Drilling and tapping processes suffer from secondary positioning deviations, making it difficult to guarantee thread accuracy. Furthermore, the lack of a precise sorting mechanism for shaft core feeding easily leads to multiple incorrectly supplied shafts. Assembly relies on manual intervention, limiting assembly accuracy and efficiency. Overall, the lack of a PLC system for comprehensive process control results in poor coordination between processes, weak equipment flexibility, and difficulty in quickly adapting to the production needs of different product specifications.

[0017] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0018] like Figure 1 As shown in the figure, the present invention provides a fully automatic production line for door and window hinges, including a main frame 1 symmetrically placed in the horizontal direction. Each main frame 1 is equipped with a control box 2 and a conveyor belt 3. The left main frame 1 is provided with a frame hinge feeding device 4, a frame hinge cutting device 5, a frame hinge punching device 6 and a frame hinge drilling and tapping device 7 in sequence along the direction of the conveyor belt 3. The symmetrically arranged dual main racks 1 enable parallel processing of workpieces on both sides, significantly improving production capacity and optimizing space utilization. The control box 2 integrates a PLC control system to realize sequential collaborative operation of each workstation. The conveyor belt 3 adopts variable frequency speed regulation technology to ensure the continuity and stability of material flow between each process.
[0019] The right-side main frame 1 is provided with a fan hinge feeding device 8, a fan hinge cutting device 9, a fan hinge punching device 10, and a fan hinge drilling and tapping device 11 in sequence along the direction of the conveyor belt 3. The independently configured fan hinge processing module and frame hinge module form a mirror configuration. The modular design meets the differentiated processing needs of different components, and the layout of simultaneous production on both sides shortens the production cycle, making it particularly suitable for production scenarios with large-volume orders.
[0020] An assembly platform 12 is provided at the intersection of the two conveyor belts 3. A shaft core feeding device 13 is provided on one side of the assembly platform 12, and a finished product assembly mechanism 14 is provided at the bottom of the assembly platform 12.
[0021] The assembly platform 12 at the intersection of conveyor belts 3 serves as a key hub, integrating automatic core feeding and finished product assembly functions, achieving seamless connection from disassembled parts to finished products.
[0022] like Figure 2 As shown, the frame hinge feeding device 4 includes a raw material placement rack 41 and a raw material conveying mechanism 42; The raw material placement rack 41 is fixedly installed on the ground, and its rotating shaft is at the same horizontal position as the conveyor belt 3. The starting end of the conveyor belt 3 is located on the raw material conveying mechanism 42.
[0023] The raw material placement rack 41 adopts a low-level storage design, which reduces the labor intensity of workers loading materials. The structure of the rotating shaft being flush with the conveyor belt 3 eliminates the height difference of material transfer and reduces the risk of material deviation caused by gravity acceleration. The raw material conveying mechanism 42 is connected to the conveyor belt 3 to form a continuous material supply chain, avoiding the energy consumption of equipment idling caused by traditional intermittent loading.
[0024] The raw material conveying mechanism 42 includes a first guide roller 421, a first slider 422, a first slide rail 423, a first cylinder 424, and a first motor 425; Two first guide rollers 421 are provided and distributed along the vertical direction of the main frame 1. The lower first guide roller 421 is rotatably connected to the inner wall of the main frame 1, and the two ends of the upper first guide roller 421 are fixedly connected to the first slider 422 respectively. The first slide rail 423 is embedded in the main frame 1, and the first slider 422 is slidably disposed in the first slide rail 423; The first cylinder 424 and the first motor 425 are both fixedly installed on the outside of the main frame 1. The output end of the first cylinder 424 passes through the main frame 1 and is fixedly connected to the first slider 422. The output end of the first motor 425 passes through the main frame 1 and is fixedly connected to the conveyor shaft of the conveyor belt 3.
[0025] The upper and lower double-layer first guide rollers 421 constitute a composite guiding system. The upper first guide roller 421 achieves height self-adjustment through a slider-rail mechanism, which can be compatible with metal plates of different thicknesses. The first slider 422 works in conjunction with the first rail 423 to ensure smooth and jam-free material conveying.
[0026] The first slider 422 driven by the first cylinder 424 can achieve rapid forward and backward movement. Combined with the rotational speed of the first guide roller 421 controlled by the first motor 425, a "push-convey" composite motion mode is formed, which ensures both the accuracy of material feeding and the conveying efficiency. The first motor 425 is a servo motor with an encoder to achieve closed-loop control of the conveying speed.
[0027] like Figure 3 As shown, the frame hinge cutting device 5 includes a first hydraulic cylinder 51, a raw material cutting knife 52, and a raw material mold cutting knife 53; The first hydraulic cylinder 51 is fixedly installed on the outside of the main frame 1, and its output end is fixedly connected to the upper end of the raw material cutting knife 52 and the raw material mold cutting knife 53. The raw material cutting blade 52 is located at one end near the frame hinge feeding device 4; The raw material mold cutter 53 is located at one end away from the frame hinge feeding device 4.
[0028] The dual-blade configuration enables graded processing of roughing and fine cutting. The raw material cutting blade 52 is responsible for the initial cutting, while the raw material mold cutting blade 53 completes the precision cutting of irregular contours. The first hydraulic cylinder 51 provides constant pressure output to ensure that the cut is flat and burr-free. The distance between the two blades can be digitally adjusted according to the product size parameters. When switching models, only the CNC program needs to be modified, which greatly shortens the mold change time.
[0029] like Figure 4 As shown, the frame hinge stamping device 6 includes a first stamping machine 61, a first punching die 62, a first frame hinge bending die 63, a second frame hinge bending die 64, and a third frame hinge bending die 65. The first stamping press 61 is hollow in the middle, and the conveyor belt 3 extends out from the middle of the first stamping press 61; The first punching die 62, the first frame hinge bending die 63, the second frame hinge bending die 64, and the third frame hinge bending die 65 are placed sequentially along the direction of the conveyor belt 3.
[0030] The hollow design of the first stamping press 61 allows the conveyor belt 3 to pass through, realizing a dynamic operation mode of "processing while moving". Multiple sets of bending dies are arranged in the process sequence, which can complete the continuous bending of complex shapes at one time. The control box 2 real-time monitoring system can automatically compensate for material thickness deviation and ensure the stability of forming quality.
[0031] like Figure 5 As shown, the frame hinge drilling and tapping device 7 includes a first electric cylinder 71 and a thread drill bit 72; The first electric cylinder 71 is fixedly installed on the outside of the main frame 1, and its middle part is hollow. The conveyor belt 3 passes through the middle part of the first electric cylinder 71. The end of the threaded drill bit 72 is fixedly mounted on the output shaft of the first electric cylinder 71, and the number of threaded drill bits 72 and the corresponding drilling positions are equal to those of the first punching die 62.
[0032] The thread drill bit 72 driven by the first electric cylinder 71 can achieve high-speed forward and reverse rotation, and immediately perform tapping operation after drilling, reducing the number of clamping operations. The hollow structure of the first electric cylinder 71 facilitates the removal of iron filings and extends the service life of the tool. The axis of the thread drill bit 72 is kept perpendicular to the conveyor belt to ensure hole position accuracy. The first electric cylinder 71 has a built-in overload protection device that automatically stops the machine when encountering abnormal resistance to prevent damage to the equipment. The strict correspondence between the number of 72 thread drill bits and the punching position ensures that each pre-punched hole can achieve precise thread processing. This matching design eliminates secondary positioning errors and is particularly suitable for high-precision hinge connection hole processing. At the same time, it simplifies the programming logic, and only requires calling the same set of coordinate data to complete the linkage control of two processes.
[0033] like Figure 6 As shown, the shaft core feeding device 13 includes a feeding box 131, a feeding trough 132, a push rod 133, and a shaft core cylinder 134; The feeding box 131 is fixedly installed on the upper surface of the main frame 1. Its upper surface has an opening smaller than the feeding box 131. One side of the feeding box 131 has a slot for the shaft core to pass through. The feeding box 131 is provided with a feeding groove 132 in the opening direction; One end of the push rod 133 is located in the feeding trough 132, and the other end is fixedly connected to the output end of the shaft cylinder 134.
[0034] The feeding box 131 uses gravity to achieve orderly arrangement of shaft cores, and the anti-disorder structure ensures that only a single shaft core is released each time. The push rod 133 is wrapped with elastic material to ensure pushing force while avoiding scratching the shaft body. The shaft core cylinder 134 drives the shaft core to meet the needs of high-speed assembly. The bottom tilt angle of the feeding groove 132 has been calculated and optimized to ensure that the shaft core rolls smoothly to the designated position.
[0035] The assembly platform 12 has a hole of the same size as the push rod 133 on the side relatively close to the push rod 133, and a double door 15 with a hollow bottom. The double door 15 is hinged to the inner wall of the assembly platform 12 and electrically connected to the control box 2. A conveyor belt 3 is provided below the double door 15.
[0036] The precisely matched hole design allows the push rod 133 to extend fully out of the surface of the assembly platform 12, accurately delivering the shaft core into the assembly station. This structure facilitates observation of the assembly status and provides an unobstructed view. The double door 15 design enables automatic unloading of finished products. When the control box 2 detects that the finished product has arrived, the double door 15 opens quickly, and the conveyor belt 3 below transports the finished product away from the assembly area. The hollow assembly platform 12 facilitates the cleaning of fallen small parts. The double door 15 ensures smooth opening and closing and good sealing to prevent dust from entering.
[0037] like Figure 7 As shown, the finished product assembly mechanism 14 includes symmetrically distributed assembly push rods 141 and assembly cylinders 142; The assembly platform 12 has square through holes on both sides, and the assembly push rod 141 is located in the square through holes and can slide. The assembly cylinder 142 is fixedly mounted on the upper surface of the main frame 1, and its output end is fixedly connected to the end of the assembly push rod 141.
[0038] The two symmetrically arranged assembly units can process the workpieces on the left and right sides at the same time, doubling the assembly efficiency. The square through hole serves as a guide rail, restricting the movement trajectory of the assembly push rod 141 and ensuring the straightness of the assembly action. The assembly cylinder 142 ensures the vertical transmission of the assembly force.
[0039] The fan hinge feeding device 8, fan hinge cutting device 9, fan hinge stamping device 10, and fan hinge drilling and tapping device 11 have the same structure as the frame hinge feeding device 4, frame hinge cutting device 5, frame hinge stamping device 6, and frame hinge drilling and tapping device 7, respectively.
[0040] The completely identical left and right main frame design not only facilitates equipment maintenance but also enables the interchangeability of parts, reducing spare parts inventory costs. The symmetrical structure provides uniform stress distribution, effectively extending the service life of the equipment. The standardized modular design also reserves interfaces for subsequent production line expansion, supporting the addition of more processing units.
[0041] In summary, the fully automated door and window hinge production line provided by this utility model embodiment, during use, coordinates the entire process operation through a PLC control system. The left main frame 1 sequentially executes the frame hinge production process: the raw material is smoothly conveyed to the raw material conveying mechanism 42 via the raw material placement rack 41, and precise feeding is achieved by cylinder-motor linkage; after entering the cutting station, the raw material cutting knife 52 and the raw material mold cutting knife 53 driven by the first hydraulic cylinder 51 complete the rough cutting and irregular fine cutting of the raw material; subsequently, the first punching machine 61, together with the first punching mold 62, the first frame hinge bending mold 63, the second frame hinge bending mold 64 and the third frame hinge bending mold 65, performs dynamic continuous bending forming; the first The thread drill 72 driven by the electric cylinder 71 completes the thread processing synchronously, and the number of thread drills 72 corresponds strictly to the punching position to eliminate secondary positioning errors. At the same time, the fan hinge processing module is mirrored on the right main frame 1 to realize parallel production on both sides. The processed components are delivered to the assembly platform 12 via the conveyor belt 3. The shaft core feeding device 13 achieves precise feeding of a single shaft core through the push rod 133 and the shaft core cylinder 134. The symmetrically arranged assembly push rods 141 complete the precision assembly of the hinge and the shaft core under the drive of the assembly cylinder 142. The finished product is automatically unloaded to the output conveyor belt 3 through the double door 15 at the bottom of the assembly platform 12, forming a fully automated closed-loop production system from raw material feeding to finished product delivery.
[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
