Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a high-precision aluminum profile cutting device. Background Technology

[0002] Aluminum profiles are aluminum alloy materials produced through an extrusion process, typically with a specific cross-sectional shape. They are made primarily of aluminum, with small amounts of other alloying elements (such as copper, magnesium, and silicon), through processes including smelting, extrusion, and cooling. Due to their excellent properties, aluminum profiles are widely used in the construction industry for door and window frames, curtain walls, stair railings, as well as in transportation and machinery manufacturing.

[0003] Aluminum profiles require cutting and trimming according to specific application scenarios. During the cutting process, quality issues such as cut defects and dimensional inaccuracies often arise. High-speed rotating cutters generate eccentric motion, causing axial vibration, and the cutter edge's rotation trajectory deviates under centrifugal force, producing periodic ripples. Furthermore, errors in the positioning of the fixing fixtures during aluminum profile cutting cause deviations in the actual position. All these factors reduce the cutting accuracy of aluminum profiles, which directly affects the quality of their operation. For example, deviations in the cut length of door and window frames can prevent the four corners from closing properly, affecting their airtightness. After curtain wall unit installation, deviations in frame length can lead to stress concentration in the glass, increasing the risk of glass breakage. Therefore, a device is needed to improve the cutting accuracy of aluminum profiles, reduce product scrap rates, and lower carbon emissions during waste recycling. Utility Model Content

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention utilizes a rolling component in the cutter stabilization device that fits into the cutter.

Detailed Implementation

[0030] 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.

[0031] Example 1:

[0032] like Figure 1 , 4As shown, this utility model discloses a high-precision aluminum profile cutting device, including a cutting table 1 and a cutter 2, with the cutter 2 positioned at the center of the cutting table 1. It also includes a cutter stabilizing device 3, positioned above the cutter 2. The cutter stabilizing device 3 comprises a U-shaped plate 31 and two mounting bases 32. The U-shaped plate 31 is mounted above the cutter 2, with its open ends fixedly connected to the mounting bases 32. Both mounting bases 32 are fixedly mounted on the cutting table 1. Grooves 35 are provided on the inner walls of the two sides near the top of the U-shaped plate 31. Multiple rolling components 36 are provided within the grooves 35, each rolling component 36 being in contact with the surface of the cutter 2. The rolling components 36 are ball bearings 363 disposed within the grooves 35. After the ball bearings 363 are in contact with the cutter 2, when the cutter 2 rotates at high speed, the friction between the cutter 2 and the ball bearings 363 drives the ball bearings 363 to rotate as well. The ball bearing 363 can suppress the deviation of the rotation trajectory under the action of centrifugal force, avoid the periodic ripples generated by the cutter during the cutting process, and thus avoid cutting errors. At the same time, it can prevent the cutter stabilization device 3 from reducing the speed of the cutter 2 and affecting the cutting efficiency.

[0033] In this utility model, the ball bearings in the cutter stabilization device are in close contact with the cutter. When the cutter is rotating at high speed, the ball bearings will suppress the deviation of the rotation trajectory under the action of centrifugal force without affecting the rotation speed, thus avoiding the generation of periodic ripples in the cutter during the cutting process and causing cutting errors.

[0034] Example 2:

[0035] like Figures 1-3As shown, this utility model discloses a high-precision aluminum profile cutting device, including a cutting table 1 and a cutter 2, with the cutter 2 positioned at the center of the cutting table 1. It also includes a cutter stabilization device 3, positioned above the cutter 2. The cutter stabilization device 3 comprises a U-shaped plate 31 and two mounting bases 32. The U-shaped plate 31 is mounted above the cutter 2, with its open ends fixedly connected to the mounting bases 32. Both mounting bases 32 are fixedly mounted on the cutting table 1. Grooves 35 are provided on the inner walls of the two sides near the top of the U-shaped plate 31. Multiple rolling components 36 are provided within the grooves 35, each rolling component 36 fitting against the surface of the cutter 2. Each rolling component 36 includes a fixed shaft 361 and rotating wheels 362. The fixed shaft 361 is fixedly connected within the groove 35, and multiple rotating wheels 362 are connected to its shaft. After the rotating wheel 362 is in contact with the cutter 2, when the cutter 2 rotates at high speed, the friction between the cutter 2 and the rotating wheel 362 will drive the rotating wheel 362 to rotate as well. On the one hand, the rotating wheel 362 can suppress the deviation of the rotation trajectory under the action of centrifugal force, and avoid the cutter from generating periodic ripples during the cutting process, thereby causing cutting errors. On the other hand, the rolling assembly 36 can rotate together, preventing the rotating wheel 362 from reducing the rotation speed of the cutter 2 and affecting the cutting efficiency. A triangular fixing piece 33 is fixedly connected to the top of each of the mounting bases 32. The triangular fixing piece 33 can increase the connection stability between the mounting base 32 and the "U"-shaped plate 31, ensuring that the cutter stabilization device 3 can be stably set on the base 32.

[0036] In this embodiment, as Figure 1 , 5As shown, the cutting table 1 is equipped with two "T"-shaped slide rails 4, both parallel to the cutter 2. Each "T"-shaped slide rail 4 is equipped with a clamp mounting seat 41, the bottom of which matches the "T"-shaped slide rail 4 to ensure that the clamp mounting seat 41 can slide horizontally on the "T"-shaped slide rail 4. Each end of each "T"-shaped slide rail 4 is equipped with a limiting block 42. Each clamp mounting seat 41 is equipped with a pneumatic clamp 5. The pneumatic clamp 5 has two grippers 51 on its upper part, and each gripper 51 has a soft rubber layer 52 on its inner side. The "T"-shaped slide rail 4 and the clamp mounting seat 41 cooperate to allow the pneumatic clamp 5 to slide horizontally on the "T"-shaped slide rail 4. The pneumatic clamp 5 controls the output force through a pneumatic pressure regulating valve to provide specific clamping force, preventing deformation of the aluminum profile. It can clamp with high precision, reducing machining allowance. Compared with intermittent air supply from an air compressor, it is 60% more energy-efficient than a hydraulic system. The soft rubber layer 52 on the gripper 51 can effectively provide excessive clamping force while preventing deformation of the aluminum profile. Through precise force control, rapid response, and flexible adaptation, the pneumatic clamp can improve the fixing stability of the aluminum profile and reduce cutting errors.

[0037] In this embodiment, as Figures 1-3 As shown, a pressure oil reservoir 6 is fixedly connected above the cutter stabilization device 3; each of the two plates of the "U"-shaped plate 31 is equipped with an oil supply pipe 61, and each oil supply pipe 61 is connected to the pressure oil reservoir 6; on the inner walls of the two sides near the bottom of the "U"-shaped plate 31, there is a lubricating oil nozzle 62, and each lubricating oil nozzle 62 is connected to the oil supply pipe 61. The pressure oil reservoir 6 delivers lubricating oil to the lubricating oil nozzle 62 through the oil supply pipe 61. The lubricating oil nozzle 62 evenly sprays lubricating oil to the vicinity of the rotating shaft of the cutter 2. During the high-speed rotation of the cutter, the lubricating oil diffuses towards the edge of the cutter 2 under the action of centrifugal force to reduce the cutting error caused by the friction between the aluminum profile and the cutter 2.

[0038] This invention utilizes a cutting blade stabilization device where a rotating wheel engages with the cutting blade. When the cutting blade rotates at high speed, the rotating wheel suppresses rotational trajectory deviation under centrifugal force without affecting the rotational speed, preventing periodic ripples and cutting errors during the cutting process. The pneumatic clamp in this design securely positions and fixes the aluminum profile to be cut, avoiding errors caused by unstable clamping during cutting. The pressure oil reservoir and lubricating oil nozzle work together to spray lubricating oil near the cutting blade's rotation axis. Under centrifugal force, the lubricating oil spreads towards the edge of the cutting blade, reducing friction between the cutting blade and the aluminum profile during cutting and minimizing stress concentration caused by friction, thus reducing cutting errors.

[0039] Although the present invention 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 invention should be included within the protection scope of the present invention.
