Description

Technical Field

[0001] This invention relates to the field of hinge production line technology, and more particularly to a hinge production line. Background Technology

[0002] A hinge is a device used for connection or rotation, allowing doors, covers, or other swinging parts to be opened or closed by rotation. It typically consists of a pair of metal leaf sleeves connected by a pin. As the most important component of a swing door, the hinge is responsible for bearing the entire weight and ensuring smooth opening of the door leaf.

[0003] The existing hinge production process is too complex, with low production efficiency and a lot of wasted raw materials. The cumbersome and complicated production process also requires multiple handling and feeding of production materials during the production process. Moreover, in order to ensure the stability of cutting, the end of the hinge usually needs to be placed inside the drop rail before cutting. The cut hinge needs to be pushed to the end of the drop rail by the subsequent hinge before it can be dropped, which causes the hinge to stay in the drop rail for a long time, resulting in low dropping efficiency.

[0065] In one embodiment of the present invention, such as Figure 1-15As shown, a hinge production line includes a first feeding device 11, a second feeding device 12, a straightening device 21, a first punching device 22, a cutting device 23, an oil tank 3, a winding device 4, a first conveying device 51, a second conveying device 52, a pressing and shaping device 6, a second punching device 7, a folding and unloading device 8, a drilling device 9, a placement rack 101, and a height rack 102. The first feeding device 11 is located to the left of the straightening device 21. The first feeding device 11 is used to feed hinge sheet material, and the straightening device 21 is used to straighten and level the hinge sheet material. The first punching device 22 is located on the left side of the straightening device 21. On the right side of 1, the first punching device 22 is used to punch rectangular holes in the hinge sheet material. The cutting device 23 is located to the right of the first punching device 22 and is used to cut the hinge sheet material into two halves. The second feeding device 12 is located behind the first feeding device 11 and is used to feed the central shaft core. The oil tank 3 is located to the right of the cutting device 23 and is equipped with a partition column 31. The winding and threading device 4, the first conveying device 51, the pressing and forming device 6, and the second punching device 7 are respectively installed on the placement frame 101. The winding and threading device 4 is located on the right side of the first feeding device 11. On the right side of the oil tank 3, the winding and threading device 4 is used to install the central shaft core onto two long hinge pieces and form a long hinge. The first conveying device 51 is located to the right of the winding and threading device 4 and is used to convey the long hinge. The pressing and forming device 6 is located to the right of the first conveying device 51 and is used to press and shape the formed long hinge again. The second punching device 7 is located to the right of the pressing and shaping device 6 and is used to punch through holes in the formed hinge. The height frame 103 is installed on the placement frame 101, and the folding and unloading device... The placement frame 8 includes a cutting assembly 81, an auxiliary support assembly 82, a folding and unloading assembly 83, and an unloading rail 84. The second conveying device 52, the cutting assembly 81, and the drilling device 9 are respectively installed on the height frame 103. The second conveying device 52 is located to the right of the drilling device 9, and the cutting assembly 81 is located to the left of the drilling device 9. One end of the unloading rail 84 is connected to the cutting assembly 81, and the other end of the unloading rail 84 is installed on the auxiliary support assembly 82. The bottom surface of the unloading rail 84 is provided with an unloading groove 841. The auxiliary support assembly 82 is installed on the placement frame 101.The folding and unloading assembly 83 is installed on the unloading rail 84. Multiple folding and unloading assemblies 83 are arranged along the length of the unloading rail 84. Each folding and unloading assembly 83 abuts against the central axis of the hinge, causing the hinge to fold along the central axis and unload from the unloading groove 841. In this embodiment, the first feeding device 11, the second feeding device 12, the straightening device 21, the first punching device 22, the cutting device 23, the pressing and forming device 6, the second punching device 7, and the drilling device 9 are all prior art. During operation, the first feeding device 11 conveys the hinge sheet material to the straightening device 21 for straightening and leveling. After straightening and leveling, the hinge sheet material is punched with rectangular through holes by the first punching device 22, and then the cutting device 23 cuts the hinge sheet material into two halves as required. When the two long hinge halves pass through the oil tank 3, they are separated by the dividing post 31. To prevent the two long hinge pieces from tangling or colliding and scratching each other, the second feeding device 12 conveys the central core to the winding and threading device 4. The winding and threading device 4 then installs the central core at the connection point of the two long hinge pieces, forming a long hinge. The first conveying device 51 provides power to convey the long hinge. After being formed, the long hinge passes through the pressing and shaping device 6 and is then conveyed to the second drilling device 7 for punching holes, laying the foundation for subsequent drilling. The long hinge is then bent and flipped upwards along the conveying direction and conveyed to the second conveying device 52. Flipping the long hinge facilitates observation of the drilling process and assessment of the drilling quality. The second conveying device 52 provides power to convey... A long hinge is conveyed by a power supply. After being drilled by the drilling device 9, the long hinge passes through the cutting assembly 81 and enters the discharge rail 84. The cutting assembly 81 cuts the long hinge to the required length according to production needs. The cut hinge is then located in the discharge rail 84. Then, the output end of the folding and discharge assembly 83 extends downward and abuts against the central axis of the hinge. The hinge folds along the central axis and falls from the discharge chute 841. A conveyor line or discharge box can be set below the discharge chute 841 to facilitate the conveying or collection of products. This application utilizes the first feeding device 11, the second feeding device 12, the straightening device 21, and the first... The punching device 22, the cutting device 23, the separator column 31 of the oil tank 3, the winding device 4, the first conveying device 51, the second conveying device 52, the pressing and shaping device 6, the second punching device 7, the folding and blanking device 8, the drilling device 9, the placement rack 101, and the height rack 102 allow the hinge sheet material to sequentially pass through leveling, punching rectangular holes, cutting into two long hinge sheets, separating the two hinge sheets, winding the central core and the two hinge sheets into a long hinge, shaping the long hinge, punching through holes, flipping and drilling holes, cutting into hinges of the required length, and blanking the material. This process is convenient and fast, and achieves the effect of improving the production efficiency and production quality of the hinge production line.Furthermore, through the cutting component 81, the folding and unloading component 83, and the unloading groove 841 of the unloading rail 84, long hinges are cut according to production requirements and then unloaded from the unloading groove 841. They do not need to be pushed to the end of the unloading rail 84 by subsequent hinges, thus avoiding the problem of hinges lingering in the unloading rail for extended periods. This improves the unloading efficiency of the folding and unloading device 8. Additionally, the folding and unloading component 83 is three in number and is evenly distributed along the length of the unloading rail 84, facilitating the folding and unloading of hinges of different lengths after cutting, thereby improving the versatility of the folding and unloading device 8.

[0066] like Figure 4-7 As shown, the folding and unloading assembly 83 includes a first driving unit 831, a fourth mounting base 832, and a top plate 833; mounting plates 842 are respectively provided on the front and rear sides of the unloading rail 84, and the front and rear ends of the fourth mounting base 832 are respectively mounted on the two mounting plates 842; the top of the unloading rail 84 is provided with a clearance groove 843, which is directly opposite the unloading groove 841; the first driving unit 831 is mounted on the fourth mounting base 832, and the top plate 833 is mounted on the output end of the first driving unit 831; the first driving unit 831 is used to drive the top plate 833 to move up and down, and the top plate 833 is located in the clearance groove 843; the top plate 833 is provided with rounded corners 8331, which face the material receiving direction of the unloading rail 84. In this embodiment, the first driving unit 831 is a cylinder, which is mounted on the top surface of the fourth mounting base 832. The output end of the first driving unit 831 passes through the fourth mounting base 832 and is connected to the top plate 833. The top plate 833 can move up and down within the clearance groove 53. During operation, when the hinge is conveyed to the area below the top plate 833, the output end of the first driving unit 831 extends, causing the top plate 833 to move downward within the clearance groove 843. This causes the bottom of the top plate 833 to abut against the central axis of the hinge, thereby causing the hinge to fold and fall from the drop chute 841, which is convenient and quick. The top plate 833 is provided with rounded corners 8331, which face the material feeding direction of the drop rail 84. This prevents the right angle of the top plate 833 from jamming or even damaging the moving long hinge, ensuring the production quality of the product and the service life of the top plate 833.

[0067] like Figure 4-7As shown, the auxiliary support assembly 82 includes a support frame 821, a support wheel 822, and a hanger 823.

It also includes a second drive unit 85. The height frame 102 is provided with a slide rail 1021. The cutting assembly 81 is movably mounted on the slide rail 1021. The second drive unit 85 is used to drive the cutting assembly 81 to move left and right. The support wheel 822 is rotatably mounted on the support frame 821, and the hanger 823 is movably hung on the support wheel 822. In this embodiment, one end of the dropping rail 84 is connected to the cutting assembly 81, and the other end of the dropping rail 84 is hung on the support wheel 822 of the support frame 821 via the hanger 823, thereby improving the installation stability of the dropping rail 84. In this embodiment, the second drive unit 85 is a cylinder, which is mounted on the height frame 1021. The output end of the second drive unit 85 is connected to the cutting assembly 81. By extending and retracting the second drive unit 85, the cutting assembly 81 moves left and right on the height frame 1021, thereby moving the dropping rail 84 left and right. This allows control of the hinge's dropping position, improving the applicability of the folding and dropping device. Furthermore, the rotatable support wheel 822 and the hanger 823 enhance the smoothness and stability of the dropping rail 84's movement.

One end of the first conveying roller 521 is equipped with the first gear 524, and the first conveying roller 522... The other end of 1 is equipped with the first pulley 526, and the end of the second conveying roller 522 is equipped with the second gear 525, which meshes with the first gear 524; the fourth drive unit 529 is mounted on the fixed base 523, and the output end of the fourth drive unit 529 is equipped with the second pulley 527, which is connected to the first pulley 526 through the transmission belt 528; the fixed base 523 is provided with a sliding groove 5231, and the guide wheel 5210 is slidably mounted in the sliding groove 5231. In this embodiment, the first conveying device 51 and the second conveying device 52 have the same structure. The fourth drive unit 529 is a motor. The interior of the fixed base 523 has a hollow structure. The first conveying roller 521 and the second conveying roller 522 are both installed inside the fixed base 523. One end of the first conveying roller 521 is equipped with the first gear 524, and the other end of the first conveying roller 521 passes through the side wall of the fixed base 523 and protrudes from the side wall of the fixed base 523, and is equipped with the first pulley 526. The second conveying roller 522 is located above the first conveying roller 521. During operation, the fourth drive unit 529 drives the second pulley 527 to rotate. 7. The first pulley 526 is driven to rotate by the transmission belt 528, thereby causing the first conveying roller 521 to rotate. The first conveying roller 521 causes the second conveying roller 522 to rotate through the first gear 524 and the second gear 525. The long hinge is located between the first conveying roller 521 and the second conveying roller 522, thereby achieving the purpose of conveying. It is convenient, fast and stable. Furthermore, there are four sliding grooves 5231 and four guide wheels 5210. The four guide wheels 5210 can be slidably installed in the sliding grooves 5231. The two guide wheels 5210 can not only guide the long hinge and improve its smooth movement, but also be suitable for guiding and conveying long hinges of different widths, with high versatility.

[0071] like Figure 10As shown, the threading device 4 includes an auxiliary turning component 41, a pre-bending component 42, and a threading component 43. The auxiliary turning component 41, the pre-bending component 42, and the threading component 43 are respectively installed on the top surface of the placement rack 102. The auxiliary turning component 41 is located to the left of the pre-bending component 42 and is used to assist the long hinge in changing from a horizontal state to a vertical state. The pre-bending component 42 is located to the left of the threading component 43 and is used to initially bend the long hinge pieces into shape. The threading component 43 is used to roll the two long hinges into a circle and thread them into the central core. In this embodiment, during operation, two long hinge pieces are conveyed from the previous process to the auxiliary transition component 41. The auxiliary transition component 41 gradually changes the two long hinge pieces from a horizontal conveying state to an inclined conveying state, and finally to a vertical conveying state. Then, the two vertically positioned long hinge pieces are inserted into the pre-bending component 42. The pre-bending component 42 performs preliminary bending and shaping on the two long hinge pieces. It should be noted that the central core of the hinge passes through the auxiliary transition component 41 and the pre-bending component 42 in sequence, and is inserted into the rolled-up portion of the two long hinge pieces in the rolling-through component 43. Specifically, the rolling-through component 43 first rolls up the bent portion of the two long hinge pieces. Then, the rolled-up portions of the two long hinge pieces are used to tightly wrap and form the inserted central core. This application, through the auxiliary transition component 41, the pre-bending component 42, and the winding and threading component 43, enables the long hinge pieces to be conveyed in a straight state before the auxiliary transition component 41 changes state. This is convenient, fast, and less prone to collision damage, thereby improving the conveying efficiency and production quality of the long hinge pieces. After the auxiliary transition component 41 changes state, the long hinge pieces can gradually change from a horizontal state to a vertical state, which facilitates the bending and forming of the pre-bending component 42 and the rolling and threading component 43, thereby improving the production efficiency of the winding and threading device.

[0072] like Figure 11As shown, the auxiliary rotating component 41 includes a pad 411, a third mounting base 412, rotating wheels 413, and a synchronizing rod 414. The pad 411 is mounted on the top surface of the placement frame 102, and the third mounting base 412 is mounted on the top surface of the pad 411. The two rotating wheels 413 are rotatably mounted on the third mounting base 412, and each rotating wheel 413 has a rotating groove 4131. A gap 4132 is formed between the two rotating wheels 413. The synchronizing rod 414 is rotatably mounted on the third mounting base 412, and the two rotating wheels 413 are mounted on the synchronizing rod 414. In this embodiment, there are two rotating wheels 413, and both rotating wheels 413 are provided with rotating grooves 4131. During operation, two hinge pieces are conveyed from the previous process to the rotating wheels 413. Specifically, each long hinge piece is placed obliquely in the rotating groove 4131. During the conveying process, the long hinge piece moves in the rotating groove 4131 in an oblique state and gradually turns into a vertical state before the pre-bending assembly 42 bends it. The central core of the hinge passes through the gap between the two rotating wheels 413. The pad block 411 serves to raise the height of the third mounting base 412, thereby ensuring that the rotating groove 4131 is directly opposite the output end of the pre-bending assembly 42. The two rotating wheels 413 are respectively installed on the same synchronizing rod 414. During operation, the two rotating wheels 413 rotate synchronously with the synchronizing rod 414, thereby ensuring the synchronous conveying of the two rotating wheels 413, preventing the conveying speed difference between the two long hinge pieces, and ensuring the working stability and reliability of the winding device.

[0073] like Figure 12As shown, the pre-bending assembly 42 includes a first mounting base 421, a lower bending die 422, an upper bending die 423, a first connecting base 424, a first guide rod 425, a first fixing block 426, and a fifth driving unit 427. The first mounting base 421 is mounted on the top surface of the placement frame 102, and the lower bending die 422 is mounted on the top surface of the first mounting base 421. One end of the first guide rod 425 is mounted on the first mounting base 421, and the other end of the first guide rod 425 is connected to the first fixing block 426. The first connecting base 424 is movably mounted on the first guide rod 425, and the upper bending die 423 is mounted on the bottom of the first connecting base 424. The fifth driving unit 427 is used to drive the first connecting base 424 to move up and down. In this embodiment, the fifth driving unit 427 is a cylinder. The fifth driving unit 427 is installed on the top of the first fixing block 426. The output end of the fifth driving unit 427 passes through the first fixing block 426 and is connected to the first connecting seat 424. During operation, the two long hinge pieces that need to be bent are inserted into the lower bending die 422. The fifth driving unit 427 drives the upper bending die 423 to descend along the length direction of the first guide rod 425 through the first connecting seat 424, so that the upper bending die 423 and the lower bending die 422 are closed for bending, which is convenient and quick.

[0074] like Figure 13As shown, the lower bending die 422 is provided with a bending block 4221 and a first placement groove 4222. The first placement groove 4222 is used to place long hinge pieces. The bending block 4221 has a through hole 42211, which is used to place the central core. The two end corners of the top of the bending block 4221 are provided with bending portions 42212. The upper bending die 423 is provided with a bending groove 4231, which is directly opposite the bending portion 42212. The front and rear sides of the upper bending die 423 are respectively provided with guide blocks 4232. One end of the guide block 4232 is installed on the outer side of the upper bending die 423, and the other end of the guide block 4232 can fit against the outer side of the lower bending die 422 and move up and down. In this embodiment, there are two of each of the first placement groove 4222, the bending portion 42212, and the bending groove 4231. During operation, the two long hinge pieces are placed in the first placement groove 4222. At this time, the top of the two long hinge pieces is higher than the top surface of the bending block 4221. When the bending upper die 423 is pressed down, the top of the long hinge pieces is bent into shape under the action of the bending portion 42212 and the bending groove 4231, which is convenient and quick. The central core extends through the through hole 42211 to the winding assembly 43. In this embodiment, there are four guide blocks 4232. Two guide blocks 4232 are respectively provided on the front and rear sides of the upper bending die 423. When the upper bending die 423 moves downward, the upper bending die 423 drives the guide blocks 4232 on its front and rear sides to move downward. The inner side of the guide block 4232 is in contact with the outer side of the lower bending die 422 and moves downward. The guide block 4232 plays a guiding role to prevent the upper bending die 423 and the lower bending die 422 from misaligning when they are closed, thereby improving the production quality of the pre-bending assembly 42.

[0075] like Figure 14-15As shown, the winding assembly 43 includes a second mounting base 431, a lower clamping die 432, an upper clamping die 433, a second connecting base 434, a second guide rod 435, a second fixing block 436, and a sixth driving part 437. The second mounting base 431 is mounted on the top surface of the placement frame 102, and the lower clamping die 32 is mounted on the top surface of the second mounting base 431. One end of the second guide rod 435 is mounted on the top surface of the second mounting base 431, and the other end of the second guide rod 435 is connected to the bottom surface of the second fixing block 436. The second connecting base 434 is movably mounted on the second guide rod 435, and the upper clamping die 433 is mounted on the bottom surface of the second connecting base 434. The sixth driving part 437 is used to drive the second connecting base 434 to move up and down. The lower clamping die 432 is provided with a second placement groove 4321 for placing long hinge pieces, and the upper clamping die 433 is provided with a clamping groove 4331. In this embodiment, the sixth driving part 437 is a cylinder. The sixth driving part 437 is installed on the top of the second connecting seat 434. The output end of the sixth driving part 437 passes through the second fixing block 436 and is connected to the second connecting seat 434. There are two second placement slots 4321. During operation, the two long hinge pieces are placed in the two second placement slots 4321. Then, the sixth driving part 437 drives the pressing upper mold 433 to move downward through the second connecting seat 434. The pressing slots 4331 make the tops of the two long hinge pieces tightly wrap around the central shaft core to form a shape, which is convenient and quick.
