Description

Technical Field

[0001] This utility model relates to the field of condenser heat sink processing technology, and in particular to a drilling machine for air conditioner condenser heat sinks. Background Technology

[0002] The function of air conditioner condenser fins is to help improve the heat exchange efficiency of the air conditioner. By increasing the surface area in contact with air, they promote the transfer of heat from the refrigerant to the air, thereby lowering the condenser temperature and maintaining the efficient operation of the air conditioning system. The fins are typically installed on the outside of the air conditioner condenser, usually located in the outdoor unit. They are closely arranged around the condenser pipes, and a fan blows air to accelerate the heat dissipation process, ensuring effective heat dissipation during air conditioner operation and preventing overheating damage.

[0003] The function of a heat sink drilling machine is to increase the surface area of ​​heat sinks by drilling holes, thereby improving heat dissipation efficiency. Precise drilling optimizes airflow paths, promotes more efficient heat exchange, enhances heat dissipation, and ensures that each heat sink meets the designed hole diameter and spacing. Its importance lies in improving product performance, extending equipment lifespan, reducing energy consumption, and ensuring the stability and efficiency of equipment during long-term operation.

[0004] However, while existing heat sink drilling machines can perform basic processing functions, they still have some shortcomings. First, traditional scrap collection systems often cannot efficiently sort and clean debris of different sizes, easily causing waste accumulation or blockages, affecting the continuity and stability of production. Existing systems usually rely on manual or basic mechanical cleaning methods, which not only increases labor costs but also reduces production efficiency. Second, mold changes and hole spacing adjustments on existing drilling machines are often cumbersome, requiring mold disassembly or complex manual adjustments, which not only wastes production time but also limits production flexibility.

[0005] To address the above problems, a drilling machine for air conditioner condenser heat sinks is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a drilling machine for air conditioner condenser heat sinks, aiming to solve the problems of low scrap recycling efficiency and inconvenient hole spacing adjustment in the existing drilling machine for air conditioner condenser heat sinks during operation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a drilling machine for air conditioner condenser heat sink, including a base, a drilling machine is provided on the top of the base, a lower mold is provided on the top of one side of the drilling machine, a plurality of punches are slidably connected inside the lower mold, and a hole spacing adjustment component is provided between the two, a drilling plate is provided directly below the punches, and a storage mechanism is provided directly below the drilling plate.

[0008] The storage mechanism includes a debris collection component, a fragment collection component, and a sealing plate. The debris collection component includes a collection frame that is slidably connected inside the punching machine, and a handle is provided on the front side of the collection frame.

[0009] As a further description of the above technical solution:

[0010] The debris collection assembly includes a sieve plate located directly above the collection frame and tilted at a certain angle. A brush is provided on the top of the sieve plate, and limit plates are fixedly connected to both ends of the brush. Sliding grooves are provided on both sides of the inside of the punching machine.

[0011] As a further description of the above technical solution:

[0012] The bottom of the brush is slidably connected to the top of the sieve plate, and the limiting plate is slidably connected inside the groove.

[0013] As a further description of the above technical solution:

[0014] The sealing plate is rotatably connected to the right side of the punching machine, and the sealing plate is close to the inclined bottom of the screen plate.

[0015] As a further description of the above technical solution:

[0016] The top side of the punching machine is provided with a control area, and the bottom side of the top of the punching machine is provided with a pressure area. A support plate is fixedly connected to the bottom side of the punching disc.

[0017] As a further description of the above technical solution:

[0018] The pressure zone is located between the punch and the lower die, and the sealing plate is rotatably connected inside the support plate.

[0019] As a further description of the above technical solution:

[0020] The lower die has multiple mounting slots inside, and the punch is slidably connected inside the mounting slots.

[0021] As a further description of the above technical solution:

[0022] The hole spacing adjustment assembly includes multiple fixing pins, and multiple threaded rods are threadedly connected between the tops of the multiple horizontally arranged punches. The fixing pins are inserted between the interiors of the multiple vertically arranged punches, and a control plate is provided at the end of the multiple threaded rods.

[0023] As a further description of the above technical solution:

[0024] The punching disc has retaining edges installed on both its front and rear sides.

[0025] This utility model has the following beneficial effects:

[0026] 1. In this invention, the heat sink to be processed is placed on a perforated plate. After processing by the punch, large particles of debris fall through the large holes in the perforated plate onto a sieve plate in the lower collection mechanism, while smaller debris is filtered through the sieve plate and falls into a collection frame below. A handle allows for easy extraction of debris from the collection frame. To prevent debris accumulation and clogging of the sieve plate, the system is equipped with an adjustable limit plate and a brush. The sieve plate can be cleaned by moving the limit plate, ensuring smooth system operation. Larger debris slides laterally through the sieve plate and can be easily removed by opening the sealing plate.

[0027] 2. In this invention, multiple transverse punches are pierced by a multi-segment threaded rod, while the longitudinal punches are fixed by retaining pins. When the hole spacing needs to be changed, the operator only needs to easily pull out the retaining pins and rotate the multi-segment threaded rod to adjust the distance between the punches. This modular design greatly simplifies the hole spacing adjustment process, reduces production mold change time, and improves production efficiency. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1 - Figure 5This utility model provides an embodiment of a drilling machine for air conditioner condenser fins, comprising a base 1 with a drilling machine 2 mounted on its top for precise drilling of the fins. A control area 21 is provided on one side of the top of the drilling machine 2 for operating the equipment, adjusting parameters, and monitoring the drilling process, improving the automation and ease of use of the equipment. A pressure area 22 is provided on the lower side of the top of the drilling machine 2, which is mainly used to apply punching pressure to ensure the accuracy and consistency of the drilling. A drilling plate 6 serves as a platform for placing the fins, and a support plate 23 is fixedly connected to one side of its bottom to enhance stability and prevent displacement or vibration during the drilling process. A lower die 3 is provided on the top of one side of the drilling machine 2 for cooperating with a punch 4 to complete the drilling operation. The lower die 3 has multiple mounting grooves 31 inside to accommodate the punch 4 and ensure that the punch 4 can slide and adjust within a fixed track, thereby achieving adaptation to different hole spacings. The mounting slot 31 is equipped with a hole spacing adjustment component 5, which includes multiple multi-segment threaded rods 52 and fixing pins 51. This component can precisely control the distance between the punches 4, making adjustments quicker and avoiding the cumbersome operation of disassembling the mold required by traditional equipment. A punching plate 6 is installed directly below the punches 4 to receive the heat sink and ensure accurate punching position. At the same time, baffles 61 are installed on both the front and rear sides to prevent the heat sink from shifting or sliding during processing and to prevent debris from scattering during processing, ensuring punching accuracy and equipment cleanliness. To improve the efficiency of scrap collection, a collection mechanism 7 is provided directly below the punching plate 6, which includes a multi-stage screening device that can separate larger debris from smaller particles. Larger debris can slide laterally along the screen plate 721 and be removed by opening the sealing plate 73, while smaller debris enters the collection frame 711 below, which is pulled out by the handle 712 for recycling. In addition, the storage mechanism 7 is equipped with a limiting plate 723 and a brush 722, which can be used to clean the screen plate 721 regularly, prevent debris from accumulating and affecting normal operation, improve the overall scrap recycling efficiency, reduce material waste, and enhance the sustainability of the equipment.

[0037] Reference Figure 1 - Figure 3The collection mechanism 7 is mainly used for the efficient recycling of scrap materials generated during the drilling process, reducing debris residue during production, and improving workshop cleanliness and material utilization. The collection mechanism 7 includes a debris collection component 71, a fragment collection component 72, and a sealing plate 73. The debris collection component 71 stores smaller debris, the fragment collection component 72 separates larger waste particles, and the sealing plate 73 controls the discharge of debris, preventing leakage or accumulation that could affect equipment operation. The debris collection component 71 includes a collection frame 711, which is slidably connected to the inner bottom of the drilling machine 2 for easy removal and cleaning. A handle 712 is provided on the front side of the collection frame 711, allowing operators to easily pull out and empty the debris, improving maintenance convenience. The debris collection assembly 72 includes a sieve disc 721, which is located directly above the collection frame 711 and is designed with a certain angle of inclination to guide larger debris to slide to one side using gravity, ensuring that debris does not directly accumulate on the surface of the sieve disc 721 and affect the screening effect. A brush 722 is provided on the top of the sieve disc 721, with its bottom slidably connected to the top of the sieve disc 721. This brush can clean the surface of the sieve disc 721 when needed, preventing debris from clogging the sieve holes and improving screening efficiency. To ensure that the brush 722 slides evenly on the surface of the sieve disc 721, limit plates 723 are fixedly connected to both ends to prevent displacement from affecting the cleaning effect. The punching machine 2 has grooves 724 on both sides inside, with the limit plates 723 slidably connected inside the grooves 724 to ensure its operational stability and prevent misalignment due to impact or vibration. The sealing plate 73 is rotatably connected to the right side of the puncher 2 and hinged to the inside of the support plate 23, allowing it to open or close as needed to control the discharge of debris. The sealing plate 73 is in close contact with the inclined bottom of the screen plate 721, ensuring that larger debris screened out does not fall into the collection frame 711, but slides smoothly to the designated recycling area for centralized processing.

[0038] Reference Figure 4 - Figure 5The hole spacing adjustment assembly 5 is used to adjust the distance between the punches 4, thereby adapting to the drilling requirements of different specifications of heat sinks and improving production flexibility and applicability. The hole spacing adjustment assembly 5 mainly includes multiple fixing pins 51, multi-segment threaded rods 52, and a control plate 53. The multiple fixing pins 51 are used to connect and fix the longitudinally arranged punches 4, ensuring their stability during drilling and providing reliable fixing points when adjusting the hole spacing. The tops of the multiple laterally arranged punches 4 are connected by threads to the multi-segment threaded rods 52. These multi-segment threaded rods 52 adopt a segmented thread design, allowing the punches 4 in different areas to be adjusted independently to meet the needs of different drilling specifications. The multi-segment threaded rods 52 make the adjustment process more convenient; operators can change the distance between the punches 4 by rotating the multi-segment threaded rods 52 without disassembling the entire mold, thereby significantly improving production efficiency and reducing equipment downtime. The end of the multi-segment threaded rod 52 is provided with a control plate 53, which provides an operating interface for rotation adjustment. The operator can adjust the multi-segment threaded rod 52 synchronously by rotating the control plate 53, thereby quickly adjusting the distance between the punches 4 and ensuring the accuracy of the punching position.

[0039] Working principle: The air conditioner condenser fins to be processed are placed on top of the punching plate 6. After the punching machine 2 is started, the pressure zone 22 located on the lower side of the top of the punching machine 2 applies downward punching pressure. At the same time, the punches 4 in the lower die 3 move vertically downward under the pressure and punch holes in the fins. The operator first pulls out the fixing pin 51, and then drives the multi-segment threaded rod 52 to rotate by rotating the control plate 53, thereby driving multiple horizontally arranged punches 4 to move synchronously or independently in the mounting groove 31, changing the distance between the punches 4. After the punches 4 complete the punching, the punched debris will fall into the collection mechanism 7 located below the punching plate 6. Larger debris first falls on the screen plate 721. Due to the inclination of the screen plate 721, the debris slides down the screen plate 721 under the action of gravity and finally concentrates at the sealing plate 73. Rotating the sealing plate 73 discharges the large debris. Smaller debris falls through the sieve holes on the sieve plate 721 into the collection frame 711 below. The operator can pull out the collection frame 711 for cleaning using the handle 712. Above the sieve plate 721, the brush 722 slides along the slide groove 724 inside the punching machine 2 via the limiting plates 723 connected at both ends to clean the surface of the sieve plate 721.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
