Description

Technical Field

[0001] This utility model relates to the field of louver production and processing technology, specifically to a punching device for aluminum alloy frames. Background Technology

[0002] In the production and processing of louvers, the punching process of the aluminum alloy frame is a crucial step to ensure the assembly accuracy of the product. It is necessary to process mounting holes, ventilation holes, etc. that meet the size requirements at designated positions on the frame to facilitate the subsequent assembly of blades and connectors.

[0003] Chinese Patent Announcement No.: CN206702031U discloses a punching device for aluminum alloy frames, including a machine base and a punching machine. The punching machine is equipped with a punching table, which is divided into three layers, from top to bottom: a punching layer, a placement layer, and a base plate layer. The upper surface of the placement layer is the punching surface, and the side adjacent to the punching surface is the extrusion surface. The punching surface and the extrusion surface form a right angle. A limit block is provided at one end of the extrusion surface, and a fixture is provided at the position opposite to the extrusion surface.

[0004] However, the aforementioned patents can only achieve punching processing of a single specification. When it is necessary to process aluminum alloy frames with different hole sizes and spacings, it is necessary to frequently change molds and adjust equipment parameters. This is not only cumbersome to operate, but also greatly increases the processing preparation time, seriously affecting production efficiency and making it difficult to adapt to the needs of multi-specification and batch production of louvers. Based on this, this utility model designs an aluminum alloy frame punching equipment to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A punching device for aluminum alloy frames includes a base, on the top of which a first lower die, a second lower die, and a third lower die are fixedly connected. A collection cover is fixedly connected to the upper inside of the base, and the collection cover communicates with the first, second, and third lower dies. An installation frame is fixedly connected inside the base, and a collection box is slidably connected inside the installation frame, with the collection box located below the collection cover.

[0007] In one embodiment, springs are fixedly connected to both sides inside the mounting frame, and a limit block is fixedly connected to one end of each spring. The limit block is arc-shaped.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] In one embodiment, please refer to the appendix to the specification. Figures 1-5A punching device for aluminum alloy frames includes a base 1. A first lower die 24, a second lower die 25, and a third lower die 26 are fixedly connected to the top of the base 1. A collection cover 17 is fixedly connected to the upper part of the inside of the base 1. The collection cover 17 communicates with the first lower die 24, the second lower die 25, and the third lower die 26. An installation frame 18 is fixedly connected to the inside of the base 1. A collection box 19 is slidably connected inside the installation frame 18. The collection box 19 is located below the collection cover 17. Springs 22 are fixedly connected to both sides inside the installation frame 18. A limit block 23 is fixedly connected to one end of the spring 22. The limit block 23 is arc-shaped. Limit holes 21 are opened on both sides of the collection box 19. The limit block 23 is engaged inside the limit hole 21. A handle 2 is fixedly connected to one side of the collection box 19.

[0024] In this embodiment, the design of the collection cover 17 directly connecting with the first lower die 24, the second lower die 25, and the third lower die 26 allows aluminum chips and waste generated during punching to fall into the lower collection box 19 in real time, preventing waste from scattering onto the equipment surface or workbench, reducing cleaning workload, and preventing waste accumulation from affecting punching accuracy, thus maintaining a clean and orderly production environment. The collection box 19 is easy to assemble and disassemble, and has high maintenance efficiency: the spring 22 inside the mounting frame 18 cooperates with the arc-shaped limiting block 23 to quickly engage with the limiting holes 21 on both sides of the collection box 19 for fixation, preventing the collection box 19 from shifting during equipment operation; with the help of the handle 2 on one side, the limiting can be released and the collection box 19 can be pulled out with a gentle pull, eliminating the need for complicated waste cleaning operations and greatly improving the convenience and efficiency of equipment maintenance. 3. Stable and reliable limiting structure, extending equipment life: The arc-shaped limiting block 23 and the limiting hole 21 fit tightly together, which not only ensures the stability of the collection box 19 during operation, but also reduces mechanical wear during disassembly and assembly; the elastic force of the spring 22 can adapt to the installation position of the collection box 19, avoiding damage to components caused by hard contact, and indirectly extending the service life of key equipment structures. 4. Multi-mold collaborative design, improving production efficiency: The first lower mold 24, the second lower mold 25, and the third lower mold 26 are set synchronously above the base 1, which can simultaneously punch multiple aluminum alloy frame workpieces, or perform synchronous operations on different hole positions of the same workpiece. Compared with single-mold equipment, the processing cycle is greatly shortened, which is suitable for the batch operation needs of louver production and improves the overall production efficiency.

[0025] In one embodiment, please refer to the appendix to the specification. Figures 1-5A punching device for aluminum alloy frames, wherein fixed rods 11 are fixedly connected to the four corners above the base 1, a top plate 12 is fixedly connected to the top of the fixed rods 11, a hydraulic cylinder 13 is fixedly connected to the middle of the top plate 12, a lower pressure plate 10 is fixedly connected to the output end of the hydraulic cylinder 13, the lower pressure plate 10 and the fixed rods 11 are slidably connected, a first pressure block 14, a second pressure block 15 and a third pressure block 16 are fixedly connected below the lower pressure plate 10, the first pressure block 14, the second pressure block 15 and the third pressure block 16 are respectively located above the first lower die 24, the second lower die 25 and the third lower die 26, and a baffle 27 is provided on one side of the first lower die 24, the second lower die 25 and the third lower die 26, and the three baffles 27 are fixedly connected to the top of the base 1.

[0026] In this embodiment, the fixing rods 11 at the four corners of the base 1 and the top plate 12 form a rigid frame, providing stable support for the hydraulic cylinder 13 and the lower pressure plate 10. The lower pressure plate 10 slides with the fixing rods 11 to ensure accurate vertical displacement during the stamping process and avoid deviation. The first pressure block 14, the second pressure block 15, and the third pressure block 16 are precisely aligned with the corresponding first lower die 24, second lower die 25, and third lower die 26, which greatly improves the dimensional accuracy and positional consistency of the holes in the aluminum alloy frame, meeting the high precision requirements of louver assembly. The output end of the hydraulic cylinder 13 in the middle of the top plate 12 is directly connected to the lower pressure plate 10, resulting in a short power transmission path and low loss, which can provide stable and sufficient stamping force.

[0027] Working principle: The aluminum alloy frame workpiece to be processed is placed on the first lower die 24, the second lower die 25 and the third lower die 26 above the base 1 respectively. The position of the workpiece is quickly calibrated by the baffle 27 fixedly connected to one side of each lower die, which restricts the horizontal displacement of the workpiece during the stamping process and ensures accurate hole positioning.

[0028] The hydraulic cylinder 13, fixed in the middle of the top plate 12, is activated. The output end of the hydraulic cylinder 13 generates a downward driving force, which drives the lower pressure plate 10, which is fixedly connected to it, to slide vertically downward along the fixing rods 11 at the four corners of the base 1. The first pressure block 14, the second pressure block 15, and the third pressure block 16 below the lower pressure plate 10 move down accordingly and precisely fit with the corresponding lower molds 24 / 25 / 26. The synchronous punching process of the aluminum alloy frame is completed through the pressure action.

[0029] Aluminum shavings and waste generated during the punching process fall directly into the collection box 19 below the collection cover 17 through the connecting channels between the first lower die 24, the second lower die 25 and the third lower die 26 and the collection cover 17 inside the base 1, thereby realizing real-time centralized collection of waste and avoiding scattered pollution.

[0030] After punching is completed, the hydraulic cylinder 13 drives the lower pressure plate 10 to reset upward along the fixed rod 11. The worker can then remove the processed workpiece and proceed to the next batch of work. When the waste material in the collection box 19 accumulates to a certain amount, the handle 2 on one side of the collection box 19 is pulled outward. At this time, the spring 22 in the mounting frame 18 is compressed and contracts, and the arc-shaped limiting block 23 disengages from the limiting holes 21 on both sides of the collection box 19. The collection box 19 can then be directly pulled out to clean the waste material. After cleaning, the collection box 19 is pushed back into the mounting frame 18, and the spring 22 resets and pushes the limiting block 23 to re-engage into the limiting hole 21, thus achieving rapid fixing of the collection box 19 and ensuring continuous operation of the equipment.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
