[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figures 1-10 This embodiment provides a special component mold for 24B chains, including a chain cover unit and a chain riveting unit. The chain cover unit is used to automatically position and assemble the chain cover onto the semi-finished chain, and the chain riveting unit is used to automatically rivet and assemble the chain cover with the semi-finished chain. By automating the chain cover step in the chain assembly process, labor is saved and work efficiency is improved.

[0017] In this embodiment, as Figure 2As shown, the chain cover unit includes a punch press 1. A pair of parallel upper rails 2 are fixedly connected to the loading position of the punch press 1, forming a first conveying channel for conveying the chain. One upper rail 2 has a cover conveying mechanism 3 located at the loading position of the punch press 1 at its loading end. The other upper rail 2 has a first chain positioning mechanism 4 located at the loading position of the punch press 1, corresponding to the position of the cover conveying mechanism 3. A cover positioning mechanism 7 is located on the punch press 1 at the cover conveying mechanism 3. A chain locking mechanism 5 is located on the side of the cover conveying mechanism 3 away from the upper rails 2. A chain positioning mechanism 4, located away from the chain clamping mechanism 5, is fixedly connected to a guide chain positioning side plate at the loading position of the punch press 1. The guide chain positioning side plate corresponds to the position of the first chain positioning mechanism 4. During assembly, the semi-finished chain is conveyed in the first conveying channel formed by a pair of upper rails 2. The position of the semi-finished chain is positioned by the working mechanism 4. Then, the chain cover is conveyed by the cover plate conveying mechanism 3 and moved to the semi-finished chain. Then, the chain cover is positioned and assembled onto the semi-finished chain by the cover plate positioning mechanism 7, thus completing the assembly of the chain cover and the semi-finished chain.

[0018] In this embodiment, as Figure 5 As shown, the first chain positioning mechanism 4 includes a first positioning seat 401 fixedly connected to the punch press 1. A first positioning slider 403 is slidably installed inside the first positioning seat 401. A locking block adapted to be inserted into the semi-finished chain is provided at one end of the first positioning slider 403 near the first conveying channel. The first chain positioning mechanism 4 also includes a first positioning cylinder 402 fixedly installed on the punch press 1 for driving the first positioning slider 403 to move. The output end of the first positioning cylinder 402 is fixedly connected to the first positioning slider 403. The first positioning cylinder 402 is used to drive the first positioning slider 403 to move closer to or away from the first conveying channel. When the semi-finished chain moves into place, the first positioning cylinder 402 drives the first positioning slider 403 to move within the first positioning seat 401, moving the first positioning slider 403 closer to the first conveying channel, so that the locking block on the first positioning slider 403 is inserted into the semi-finished chain, fixing the position of the semi-finished chain and adjusting and correcting the position of the semi-finished chain to prevent the semi-finished chain from being misaligned at the cover sheet conveying mechanism 3.

[0019] In this embodiment, as Figure 3 and Figure 4As shown, the cover sheet conveying mechanism 3 includes a mounting plate 301 fixedly connected to the punch press 1. A blanking die base 302 is fixedly connected to the top of the mounting plate 301. A feeding plate 305 is slidably installed inside the blanking die base 302. A feeding cylinder 304 for driving the feeding plate 305 to move is also fixedly connected to the top of the mounting plate 301. The output end of the feeding cylinder 304 is fixedly connected to the feeding plate 305. The feeding cylinder 304 is used to drive the feeding plate 305 to move into or away from the first conveying channel. A cover sheet blanking pipe 303 is fixedly connected to the top of the blanking die base 302. The cover sheet blanking pipe 303 is connected to the cover sheet conveying equipment. The cover sheet conveying device is used to arrange chain-driven cover sheets within the cover sheet feeding tube 303. The cover sheet conveying device can employ existing technologies such as a vibrating feeder. The feeding die base 302 has a cover sheet feeding slot corresponding to the position of the cover sheet feeding tube 303. The top of the feeding plate 305 has a cover sheet receiving slot 3051 for accommodating cover sheets. A guide rail 306 is fixedly connected to the top of the mounting plate 301. The guide rail 306 drives in the same direction as the feeding cylinder 304. A guide slider 307, which slidably connects to the guide rail 306, is fixedly connected to the bottom of the feeding plate 305. A magnetic base 404 is fixedly connected to the top of the first positioning seat 401. An electromagnet for attracting cover plates is installed on the magnetic base 404. The electromagnet is electrically connected to the controller of the mold and is powered by the power supply module of the mold. The electromagnet is existing technology, and its specific structure and working principle will not be described in detail here. When the chain cover plates are fed, the feeding cylinder 304 drives the feeding plate 305 to move towards the first conveying channel. During the movement of the feeding plate 305, the feeding plate 305 slides on the guide rail 306 through the guide slider 307, which plays a limiting and guiding role for the feeding plate 305 and improves the stability of the movement of the feeding plate 305. The chain cover plates placed in the cover plate dropping tube 303 fall from the cover plate dropping tube. The material passes through the feed chute and falls into the cover plate receiving groove 3051 of the feed plate 305. It should be noted that the cover plate receiving groove 3051 can only hold one chain cover plate at a time. The feed plate 305 is driven by the operation of the feed cylinder 17 to move towards the first conveying channel. The feed plate 305 pushes out the chain cover plate at the bottom of the cover plate drop tube 303 and pushes the chain cover plate directly above the semi-finished chain. At this time, the chain cover plate is attracted by the electromagnet. Then the feed cylinder 17 retracts and returns to the origin. The chain cover plate in the cover plate drop tube 303 slides down and falls into the cover plate receiving groove 3051 of the feed plate 305, completing the feeding of the chain cover plate.

[0020] In this embodiment, as Figure 6As shown, the cover plate positioning mechanism 7 includes an upper template 701 fixedly connected to the drive end of the punch press 1. A cover plate upper die 702 is mounted at the bottom of the upper template 701, located at the first chain positioning mechanism 4. A pair of guide bumpers 703 are fixedly connected to the bottom of the cover plate upper die 702. An upper protruding die seat 704 is also mounted at the bottom of the upper template 701, and a protruding die 705 is fixedly connected to the bottom of the upper protruding die seat 704. When assembling the chain cover plate with the semi-finished chain, the punch press 1 drives the upper template 701 to descend and move, thereby causing the cover plate upper die 702 and the upper protruding die seat 704 to descend and move synchronously, so that the pair of guide bumpers 703 are inserted into the two pin holes of the chain cover plate. When the electromagnet is de-energized, it releases the attraction of the chain cover plate. The guide bumper 703 continuously moves downwards, initially assembling the chain cover plate onto the semi-finished chain. The guide bumper 703 guides the chain cover plate to fall precisely to the center of the pin on the semi-finished chain, ensuring a good initial positioning and assembly. Meanwhile, the upper protruding mold base 704 drives the protruding mold 705 to move downwards synchronously, pressing down the initially assembled chain cover plate. This allows the pin on the semi-finished chain to pass through the pin hole on the chain cover plate, effectively protruding the chain and ensuring the chain cover plate does not fall off during transport between the chain cover plate unit and the chain riveting unit.

[0021] In a preferred embodiment of this invention, a pair of guide posts are vertically fixedly connected to the upper template 701 on the punch press 1, and a guide sleeve is fixedly connected to the upper template 701 at the guide posts. The upper template 701 slides with the guide posts through the guide sleeve.

[0022] In this embodiment, as Figure 7 As shown, the chain locking mechanism 5 includes a chain locking seat 501 fixedly connected to the punch press 1. A chain locking slider 502 is slidably installed inside the chain locking seat 501. A limiting post 503 is fixedly connected inside the chain locking seat 501. A notch 5021 is opened on the chain locking slider 502 at the limiting post 503. A spring 504 is fixedly connected between one side of the limiting post 503 and the inner wall of the notch 5021. Under the action of the spring 504, the chain locking slider 502 is pushed to move inside the chain locking seat 501, moving the chain locking slider 502 towards the first conveying channel. The chain locking slider 502 presses the semi-finished chain against the guide chain positioning side plate, so that the semi-finished chain is always in an upright and taut state, so as to ensure the positioning and assembly effect of the chain cover and the semi-finished chain.

[0023] In this embodiment, as Figure 2 As shown, the chain mechanism 5, located away from the cover sheet conveying mechanism 3, is rotatably connected to the guide wheel 6 on the punch press 1. The guide wheel 6 guides the semi-finished product chain conveying.

[0024] In this embodiment, as Figure 8 and Figure 9As shown, the chain riveting unit includes a riveting table frame 8. A pair of guide rails 9 are fixedly connected to the top of the riveting table frame 8, forming a second conveying channel for conveying the chain between the pair of guide rails 9. A sprocket 12 is provided at one of the guide rails 9, with part of the sprocket 12 passing through the guide rail 9 and placed in the second conveying channel. A servo motor for driving the sprocket 12 to rotate is fixedly installed inside the riveting table frame 8. The sprocket 12 is used to drive the chain to move and convey within the second conveying channel. A second chain positioning mechanism 11 is provided on the side of one guide rail 9 near the chain cover unit, and the other guide rail 9 is near the chain cover unit. A riveting positioning side plate 10 is provided, which corresponds to the position of the second chain positioning mechanism 11. A chain riveting mechanism 13 is installed on the riveting table frame 8 at the second chain positioning mechanism 11. The initially assembled chain is conveyed in the second conveying channel formed by a pair of guide rails 9. The sprocket 12 is driven to rotate by the operation of the servo motor, which can drive the chain to advance one link at a time. The chain is fixed at the chain riveting mechanism 13 by the second chain positioning mechanism 11 in conjunction with the riveting positioning side plate 10. Then, the chain cover plate is riveted and assembled with the semi-finished chain by the chain riveting mechanism 13 to complete the chain assembly.

[0025] In this embodiment, as Figure 10 As shown, the second chain positioning mechanism 11 includes a second positioning seat 1101 fixedly connected to the top of the riveting table frame 8. A second positioning slider 1103 is slidably installed inside the second positioning seat 1101. A locking block adapted to be inserted into the chain is provided at one end of the second positioning slider 1103 near the second conveying channel. The second chain positioning mechanism 11 also includes a second positioning cylinder 1102 fixedly installed on the top of the riveting table frame 8 for driving the second positioning slider 1103 to move. The output end of the second positioning cylinder 1102 is fixed to the second positioning slider 1103. The second positioning cylinder 1102 is used to drive the second positioning slider 1103 to move closer to or away from the second conveying channel. When the chain moves into position, the second positioning cylinder 1102 drives the second positioning slider 1103 to move inside the second positioning seat 1101, moving the second positioning slider 1103 closer to the first conveying channel, so that the locking block on the second positioning slider 1103 is inserted into the chain, fixing the chain position and adjusting and correcting the chain position to prevent the chain from being misaligned at the chain riveting mechanism 13.

[0026] In this embodiment, as Figure 9As shown, the chain riveting mechanism 13 includes four riveting slide columns 1301 fixedly connected to the top of the riveting table frame 8. A riveting upper fixing plate 1302 is fixedly connected to the top of all four riveting slide columns 1301. A hydraulic cylinder 1303 is fixedly installed on the top of the riveting upper fixing plate 1302. The output end of the hydraulic cylinder 1303 passes through the riveting upper fixing plate 1302 and is fixedly connected to a movable module 1304. Sliding sleeves are fixedly connected to each of the four riveting slide columns 1301 on the movable module 1304. The movable module 1304 interacts with the riveting mechanism through these sliding sleeves. The sliding column 1301 is slidably engaged, and the bottom of the movable module 1304 is fixedly connected to the rivet head block 1305. The movable module 1304 is driven to move up and down by the working of the hydraulic cylinder 1303. The movable module 1304 slides on the rivet sliding column 1301 through the sliding sleeve, which plays a limiting and guiding role for the movable module 1304, improving the stability of the movement of the movable module 1304. The rivet head block 1305 can move up and down with the movable module 1304, and the chain cover plate is riveted and assembled with the semi-finished chain through the rivet head block 1305.

[0027] The 24B chain-specific mold in the above embodiments is suitable for assembling 24B single-row chains. In other embodiments, if it is necessary to assemble 24B double-row or triple-row chains, the upper cover mold 702 and the upper protruding mold base 704 are detachably installed with the upper template 701. The single-row upper cover mold 702 and the upper protruding mold base 704 can be removed and replaced with 24B double-row or triple-row upper cover mold 702 and the upper protruding mold base 704. Furthermore, a displacement sensor is installed on the riveting fixing plate 1302. The displacement sensor is used to detect the moving distance of the movable module 1304, that is, the length of the hydraulic cylinder 1303. By adjusting the corresponding moving distance of the movable module 1304 through the 24B double-row or triple-row chains, the assembly of 24B double-row or triple-row chains can be achieved without replacing the chain riveting mechanism 13, which is highly practical.

[0028] In this embodiment, when the chain is first conveyed from the chain cover unit and the chain riveting unit, a traction chain pulls the chain into the chain cover unit and the chain riveting unit until the sprocket 12 drives the finished chain to be output.

[0029] The control method of this utility model is through the controller of the mold. The control program of the controller can be implemented by those skilled in the art through simple programming. Therefore, the control method and circuit connection will not be explained in detail in this utility model.

[0030] Working principle: During assembly, the semi-finished chain is conveyed in the first conveying channel formed by a pair of upper rails 2. Under the action of the spring 504 of the chain clamping mechanism 5, the chain clamping slider 502 is pushed to move within the chain clamping seat 501, moving the chain clamping slider 502 towards the first conveying channel. The chain clamping slider 502 presses the semi-finished chain against the guide chain positioning side plate, keeping the semi-finished chain in an upright and taut state at all times. When the semi-finished chain moves into position, the first positioning cylinder 402 drives the first positioning slider 403 to move within the first positioning seat 401, moving the first positioning slider 403 closer to the first conveying channel. This causes the locking block on the first positioning slider 403 to insert into the semi-finished chain, fixing the position of the semi-finished chain and adjusting and correcting its position to prevent the semi-finished chain from interfering with the cover sheet conveying mechanism. With three misalignments, the feeding cylinder 17 drives the feeding plate 305 to move towards the first conveying channel. The feeding plate 305 pushes out the chain cover plate at the bottom of the cover plate drop pipe 303, pushing the chain cover plate directly above the semi-finished chain. The punch press 1 drives the upper template 701 to move downward, so that the cover plate upper mold 702 and the upper protruding mold seat 704 move downward synchronously, so that a pair of guide bumpers 703 are inserted into the two pin holes of the chain cover plate. At this time, the electromagnet is de-energized to release the attraction effect on the chain cover plate. Through the continuous downward movement of the guide bumpers 703, the chain cover plate is initially assembled onto the semi-finished chain. The upper protruding mold seat 704 drives the protruding mold 705 to move downward synchronously, pressing down the initially assembled chain cover plate, so that the pins on the semi-finished chain pass through the pin holes on the chain cover plate, thus achieving the protruding work of the chain. The semi-finished chain with the pre-positioned chain cover plate is conveyed in the second conveying channel formed by a pair of guide rails 9. A servo motor drives the sprocket 12 to rotate, enabling the chain to advance one link at a time. When the chain reaches its position, the second positioning cylinder 1102 drives the second positioning slider 1103 to move inside the second positioning seat 1101, bringing the second positioning slider 1103 closer to the first conveying channel. This causes the locking block on the second positioning slider 1103 to insert into the chain, thus positioning the chain. The chain position is fixed and adjusted to prevent misalignment at the chain riveting mechanism 13. The movable module 1304 is moved up and down via the hydraulic cylinder 1303. The movable module 1304 slides on the riveting slide post 1301 via a sliding sleeve, which limits and guides its movement, improving stability. This allows the riveting head block 1305 to move up and down with the movable module 1304, riveting the chain cover to the semi-finished chain. The above embodiment is a preferred implementation of this utility model. However, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
