Description

Technical Field

[0001] This invention relates to the field of brazing alloy processing technology, specifically to a composite rolling equipment for self-brazing alloy mixed powder and core material. Background Technology

[0002] The multilayer self-brazing alloy composite material comprises at least one or two layers of self-brazing alloy bonded to the core material. This multilayer self-brazing alloy consists of at least one layer of Al-Si alloy powder mixed with Nocolok flux and multiple Al-Si alloy plates, with the mixed powder layer sandwiched between two or more Al-Si alloy plates. The total amount of flux and the total Si element content of the multilayer self-brazing alloy are determined based on the final product thickness and usage conditions. This processing method effectively solves the problem of powder sticking to the rolls and causing rolling interruptions when directly rolling powder. Furthermore, if lubricating oil is used to lubricate the rolls, the lubricating oil penetrates into the powder, preventing the powder particles from bonding and thus hindering the deformation and bonding of the powder to the core material to form a composite plate.

[0003] Current composite rolling equipment for brazing alloy processing typically requires manual labor or a separate drive structure to add powder between alloy plates, followed by rolling with rolling rolls. The former has low automation, consumes a lot of manpower, is unsafe to operate, and has high labor costs. The latter does not utilize the movement and driving effect of the brazing alloy during the rolling process, but instead uses a separate drive structure, resulting in high production and usage costs, making it difficult to promote and causing energy waste.

[0004] To address the above issues, a composite rolling equipment for self-brazing alloy mixed powder and core material is proposed. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To address the issue that composite rolling equipment for brazing alloy processing typically requires manual labor or a separate drive structure to add powder between alloy plates before rolling via rolling rolls 3, the following solutions are needed. The former method suffers from low automation, high labor costs, and operational safety issues. The latter method fails to utilize the movement of the brazing alloy during rolling, relying instead on a separate drive structure, resulting in high production and operating costs, hindering widespread adoption, and causing energy waste. Figures 1-9 As shown, the following preferred technical solutions are provided:

[0029] A composite rolling device for self-brazing alloy mixed powder and core material includes a base 1 and a rolling shell 2 fixedly installed at the center of the top surface of the base 1. Several sets of rolling rolls 3 are arranged in the inner cavity at one end of the rolling shell 2, with each set of rolling rolls 3 arranged in parallel at equal intervals. Several upper support rolls 4 and several lower support rolls 5 are movably installed in the inner cavity at the other end of the base 1, with the upper support rolls 4 and lower support rolls 5 respectively located at the other end of the rolling rolls 3. A parallel support roll 10 is movably installed between the lower support rolls 5 and the rolling rolls 3. The alloy to be rolled first passes through the lower end of the lower support roller 5, and then enters the rolling roller 3 through the upper end of the parallel support roller 10. A vibrating roller 6 and a feeding box 7 are respectively provided at the upper end of the parallel support roller 10, and the vibrating roller 6 is located directly above the feeding box 7. A scraper block 9 is provided at one end of the lower end of the feeding box 7, and the two ends of the scraper block 9 are respectively fixedly installed on the inner wall of the inner cavity of the rolling shell 2. Storage barrels 8 are respectively inserted and fixedly installed on the top surface of the middle of both sides of the rolling shell 2, and the two ends of the feeding box 7 are respectively connected to the storage barrels 8.

[0030] A narrow through hole 21 is provided on the outer wall of the middle part of one end of the rolled shell 2, and a wide through hole 22 is provided on the outer wall of the middle part of the other end of the rolled shell 2. The narrow through hole 21 and the wide through hole 22 are connected by a rolling inner groove 23. Insertion grooves 24 are provided at the middle of both sides of the top surface of the rolled shell 2. L-shaped through holes 25 are provided on the bottom surface of the inner cavity of the insertion grooves 24. The lower ends of the L-shaped through holes 25 are connected to the rolling inner groove 23. An inner rotating groove 27 is provided on the top inner wall of the lower end of the inner cavity of the L-shaped through hole 25. A compensating inner groove 28 is provided on the inner wall of the inner cavity of the inner rotating groove 27. An inner connecting hole 26 is provided on the inner side inner wall of the inner cavity of the inner rotating groove 27. The inner end of the inner connecting hole 26 is connected to the rolling inner groove 23. An embedding groove 29 is provided on the bottom surface of the lower end of the inner cavity of the L-shaped through hole 25.

[0031] Specifically, when the operator uses the rolling shell 2 to roll the alloy, the upper alloy and the lower alloy can be passed through the upper support roller 4 and the lower support roller 5, the parallel support roller 10 and the rolling roller 3 respectively, and exit through the narrow through hole 21. During this process, the powder is laid on the surface of the lower alloy through the feeding box 7, and the powder can be evenly laid through the scraper block 9. Finally, the brazing alloy can be composite rolled through the rolling roller 3, thus solving the problem that the powder will stick to the roller when rolled directly, and ensuring the rolling effect.

[0032] The vibrating roller 6 includes a central support roller 61 and rotating shafts 62 fixedly installed on the outer walls of the middle parts of both ends of the central support roller 61. A limiting central shaft 63 is fixedly installed on the outer end of the rotating shaft 62. A multiple locking wheel 64 is fixedly sleeved on the outer peripheral wall of the middle part of the limiting central shaft 63. The rotating shaft 62 is movably installed in the inner connecting hole 26. The multiple locking wheel 64 is set in the compensation inner groove 28. A number of triangular driving blocks 641 are fixedly installed on the outer peripheral wall of the multiple locking wheel 64. The triangular driving blocks 641 are arranged densely and are connected head-to-head.

[0033] The feeding box 7 includes a feeding box body 71 and L-shaped feeding pipes 72 respectively connected and fixedly installed at both ends of the feeding box body 71. An elastic telescopic column 73 is installed at the bottom of the L-shaped feeding pipe 72. The L-shaped feeding pipe 72 is longitudinally slidably disposed within the inner cavity of the L-shaped through hole 25. The bottom of the feeding box body 71 is triangularly conical. This design allows the powder to continuously move downwards along the inclined surface of the feeding inner groove 711 during the overall shaking of the feeding box 7, thus ensuring the powder spreading effect. A feeding inner groove 711 is provided in the middle of the inner cavity of the feeding box body 71, and the shape of the feeding inner groove 711 is the same as the shape of the feeding box body 71. Several feeding holes 712 are provided on the bottom surface of the feeding box body 71, and the feeding holes 712 are respectively connected to… The inner grooves 711 are connected. The elastic telescopic column 73 includes an installation cylinder 731 and an elastic sliding groove 732 located in the middle of the top surface of the installation cylinder 731. A telescopic block 734 is elastically slidably installed at the inner opening of the elastic sliding groove 732 by a return spring 733. The installation cylinder 731 is embedded and fixedly installed in the embedded groove 29. The upper end of the telescopic block 734 is fixedly installed on the bottom surface of the L-shaped feed pipe 72. The L-shaped feed pipe 72 includes a feed pipe body 721 and an insertion slide 722 fixedly installed in the middle of the top surface of the upper end of the feed pipe body 721. A triangular driven block 723 is fixedly installed at the top of the lower end of the feed pipe body 721. The triangular driven block 723 and the triangular driving block 641 are movably engaged.

[0034] Specifically, after the upper alloy passes through the upper support roller 4 and the rolling roller 3, the upper alloy will bend in a Z-shape, causing its bottom surface to contact the surface of the middle support roller 61. Through the friction between the middle support roller 61 and the alloy surface, the middle support roller 61 will rotate while the upper alloy moves. At this time, the middle support roller 61 will drive the limiting shaft 63 to rotate through the rotating shaft 62, causing the multi-load-bearing roller 64 to rotate continuously on the triangular drive block 641. Through the setting of the triangular driven block 723, the triangular drive block 641 and the elastic telescopic column 73, the L-shaped feed tube 72 can be continuously driven to shake up and down rapidly. At this time, the powder will continuously leak out through the feed hole 712 and fall onto the surface of the lower alloy, thus realizing the addition of powder between the upper alloy and the lower alloy for rolling. It cleverly utilizes the driving effect during the movement of the alloy plate. It is not only simple in structure and fully automatic, saving production and usage costs, but also greatly saves manpower compared to manual operation, ensures processing safety, and is convenient to use.

[0035] To address the technical challenge of automatically replenishing the feeding box 7 and reducing the overall replenishment frequency, such as... Figures 4-7 As shown, the following preferred technical solutions are provided:

[0036] An L-shaped discharge hole 7211 is provided in the middle of the main body 721 of the feed tube, and the L-shaped discharge hole 7211 is connected to the inner discharge groove 711. A first funnel hole 7221 is provided in the middle of the inserted slide tube 722, and the first funnel hole 7221 is connected to the L-shaped discharge hole 7211.

[0037] The storage hopper 8 includes a hopper body 81 and a threaded pipe 82 that is fixedly installed at the middle of the top surface of the hopper body 81. The upper end of the threaded pipe 82 is fitted with a threaded cap 83. The inner cavity of the hopper body 81 is provided with a storage trough 811. The lower end of the storage trough 811 is connected to a second funnel hole 812. An insertable slide tube 722 is inserted and slidably installed in the lower end cavity of the second funnel hole 812.

[0038] Specifically, after opening the threaded cap 83, powder material can be added to the inner cavity of the barrel 81. When the feed box 7 shakes up and down continuously, it can simultaneously drive the insertion slide tube 722 to slide up and down at the lower end of the inner cavity of the second funnel hole 812, thereby continuously guiding the powder in the barrel 81 into the feed tube body 721. Then, through the shaking of the feed tube body 721 and the tilting setting of the lower end of the L-shaped feed hole 7211, powder can be continuously replenished into the feed trough 711, thereby achieving automatic feeding. The structure is ingeniously designed, and multiple effects can be achieved simultaneously by using the shaking action of the feed box 7, saving manpower and reducing the feeding frequency.
