Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, specifically a long-life double-cutting blade for heat sink production. Background Technology

[0002] With the increasing demands for heat dissipation in electrical equipment and automotive thermal management systems, the production efficiency and quality of radiator strips, as a key heat dissipation component, are becoming increasingly important. In the manufacturing process of radiator strips, the cutting process is one of the critical steps.

[0003] Traditional heat sink cutters often have the following drawbacks: the blade wears out quickly, which leads to a decline in product quality and eventually requires replacement, causing production interruptions and increasing manufacturing costs; they can only cut one heat sink at a time, resulting in low efficiency; and the cutter has a one-piece structure, making maintenance inconvenient, and if any part is damaged, the entire unit needs to be replaced, resulting in wasted resources.

[0004] Based on this, a long-life dual-cutting blade for heat sink production is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a long-life dual-cutting blade for heat sink production, which improves the blade's service life, reduces replacement frequency, and lowers operating costs. It employs a modular design to replace the integrated blade, solving the problem of needing to replace the entire blade when local performance deteriorates, thus improving product quality and resolving issues such as uneven cuts, burrs, and curled edges in heat sink production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a long-life dual-cutting blade for heat sink production, including a mounting back plate, wherein a blade assembly is provided on the outer side of the mounting back plate;

[0007] The cutting tool assembly includes an upper cutting tool holder and a lower cutting tool holder. The upper cutting tool holder is mounted on the front of the mounting back plate, and two upper cutting tool blades are mounted on the front of the upper cutting tool holder. The lower cutting tool holder is located below the upper cutting tool holder, and two lower cutting tool blades are mounted on the upper side of the lower cutting tool holder. Limiting strips are provided on both the left and right sides of the upper cutting tool holder, and pressure blocks are provided on both the upper and lower sides of the lower cutting tool holder.

[0008] Furthermore, the front of the upper cutting blade holder is provided with two first grooves that are adapted to the upper cutting blade, and the two upper cutting blades are respectively embedded in the inner side of the two first grooves.

[0009] Furthermore, the upper side of the lower cutting blade holder is provided with two second grooves that are adapted to the lower cutting blade, and the two lower cutting blades are respectively embedded in the inner side of the two second grooves.

[0010] Furthermore, the limiting strip is installed on the edge of the mounting back plate, and the lower cutting blade holder is fixed to the mounting back plate by screws passing through the limiting strip.

[0011] Furthermore, the number of pressure blocks is four, and the pressure blocks are installed on the outer wall of the limiting strip.

[0012] Compared with the prior art, this utility model provides a long-life dual-cutting blade for heat sink production, which has the following beneficial effects:

[0013] This long-life dual-cutting blade for heat sink production, with its dual-cutting design, doubles the cutting efficiency compared to traditional single-sided blades, significantly shortening the heat sink production cycle and improving production efficiency. Its modular design allows for individual replacement of each module, facilitating disassembly and installation. When the blade wears or the positioning module malfunctions, it can quickly and accurately locate and replace the corresponding module, reducing operating costs and maintenance difficulty, minimizing the risk of overall scrap due to partial failures, and improving resource utilization.

[0018] 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.

[0019] Please see Figures 1 to 3This embodiment provides a long-life dual-cutting blade for heat sink production, comprising a mounting back plate 1. A blade assembly is provided on the outer side of the mounting back plate 1. The blade assembly includes an upper cutting blade holder 2 and a lower cutting blade holder 6. The upper cutting blade holder 2 is mounted on the front of the mounting back plate 1, and two upper cutting blades 3 are mounted on the front of the upper cutting blade holder 2. The lower cutting blade holder 6 is located below the upper cutting blade holder 2, and two lower cutting blades 5 are mounted on the upper side of the lower cutting blade holder 6. Limiting strips 4 are provided on both the left and right sides of the upper cutting blade holder 2, and pressure blocks 7 are provided on both the upper and lower sides of the lower cutting blade holder 6. There are four pressure blocks 7, which are mounted on the outer wall of the limiting strips 4.

[0020] It should be noted that the upper cutting tool holder 2 and the lower cutting tool holder 6 are both made of ordinary alloy, while the upper cutting tool blade 3 and the lower cutting tool blade 5 are both made of high-strength, wear-resistant cemented carbide.

[0021] The upper cutting blade holder 2 has two first grooves on its front side that are adapted to the upper cutting blade 3, and the two upper cutting blades 3 are respectively embedded in the inner side of the two first grooves. The lower cutting blade holder 6 has two second grooves on its upper side that are adapted to the lower cutting blade 5, and the two lower cutting blades 5 are respectively embedded in the inner side of the two second grooves. The limiting strip 4 is installed on the edge of the mounting back plate 1, and the lower cutting blade holder 6 is fixed to the mounting back plate by screws passing through the limiting strip 4.

[0022] It is understandable that the two limit bars 4 are used to facilitate the positioning of the upper cutting tool holder 2, and the four pressure blocks 7 are used to facilitate the positioning of the lower cutting tool holder 6.

[0023] It should be noted that in other embodiments, the number of the first groove and the second groove can be set to a single one, so that the number of upper cutting blade 3 and lower cutting blade 5 installed is one, becoming a single-cutting tool, which is convenient to adapt to other working scenarios.

[0024] The working principle of the above embodiments is as follows:

[0025] In use, the upper cutting blade 3 is embedded into the upper cutting blade holder 2 and locked with screws. The overall structure is limited by the left and right sides of the limiting strips 4 and by the cooperation of the four pressure blocks 7. The upper cutting blade 3 is fixed to the front and rear limiting structure on the mounting back plate 1 by screws passing through the limiting strips 4 and sliding up and down relative to each other. The lower cutting blade 5 is embedded into the lower cutting blade holder 6 and locked with screws. After that, the upper cutting blade 3 is fixed to the mounting back plate 1 by screws passing through the limiting strips 4 and finally the upper cutting blade 3 slides to the lower cutting blade 5 to perform reciprocating cutting work.
