Description

Technical Field

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

[0002] Aluminum profiles, with their excellent properties such as light weight, high strength, corrosion resistance, and ease of processing, have been widely used in many fields, including building curtain walls, rail transit vehicle bodies, aerospace structural components, and electronic equipment frames. In the processing of aluminum profiles, cutting is a key process that connects profile forming with subsequent assembly. Its cutting precision directly determines the assembly adaptability, structural stability, and appearance quality of the aluminum profile.

[0003] Existing cutting devices mostly only clamp and limit the aluminum profiles on both sides, or use single-sided stops for positioning, without effectively constraining the upper end of the aluminum profile. Because aluminum profiles (especially thin-walled, long strip profiles) have relatively weak rigidity, the high-speed rotating cutting blade exerts radial impact force on the aluminum profile during cutting, causing it to move vertically or laterally. Even in devices with side limits, poor contact between the limit components and the aluminum profile surface, as well as uneven clamping force, cause slight displacement of the aluminum profile during feeding. These displacements directly lead to skewed or wavy cut ends, or deviations in cutting length exceeding design tolerances, reducing production efficiency and wasting aluminum profile material. Therefore, this invention proposes a novel solution. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a high-precision cutting device for aluminum profile processing. This device can solve the problem that offset will directly cause the cutting end face to be skewed or wavy, or cause the cutting length deviation to exceed the design tolerance, which not only reduces production efficiency, but also causes waste of aluminum profile raw materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision cutting device for aluminum profile processing, comprising a base and a cutting table;

[0006] An aluminum profile limiting component is installed on a cutting table. The aluminum profile limiting component includes a carriage, which is slidably connected to the cutting table.

[0007] The slide has two first electric telescopic rods fixedly connected inside, and aluminum profile limiting plates are fixedly connected to the output ends of the two first electric telescopic rods. Two aluminum profile support plates are fixedly connected to the inside of the slide. The two aluminum profile limiting plates are slidably connected to the corresponding aluminum profile support plates, and the two aluminum profile support plates are slidably connected to the cutting table.

[0008] The carriage is fixedly connected to connecting frames on both the left and right sides. A second electric telescopic rod is fixedly connected inside each of the two connecting frames. An aluminum profile limiting block is fixedly connected to the output end of each of the two second electric telescopic rods.

[0009] Preferably, both of the aluminum profile support plates have graduated grooves on their surfaces.

[0010] Preferably, a first guide frame and a second guide frame are fixedly connected to the lower end of the cutting table, and the first guide frame and the second guide frame are located on the left and right sides of the lower end of the cutting table, respectively.

[0011] A first drive motor is fixedly connected to the front end of the first guide frame. A threaded rod is fixedly connected to the output end of the first drive motor. The threaded rod is rotatably connected to the first guide frame. A first slide is threaded onto the surface of the threaded rod. The first slide is slidably connected to the first guide frame.

[0012] Preferably, a guide rod is fixedly connected inside the second guide frame, and a second slide is slidably sleeved on the surface of the guide rod. The second slide is slidably connected to the second guide frame, and both the first slide and the second slide are fixed to the slide frame by bolts.

[0013] Preferably, a cutting frame is installed at the upper end of the base. The cutting frame is "F" shaped, and two second drive motors are installed on the left side of the cutting frame. Cutting blades are installed at the output ends of the two second drive motors.

[0014] Preferably, the surface of the cutting table has a groove.

[0015] Preferably, the surface of the cutting table is provided with a guide groove.

[0016] Preferably, the inner side of the carriage may have two slots, which are respectively engaged with the first slide and the second slide.

[0017] Preferably, the aluminum profile limiting block can have three sliding grooves inside, and the limiting shaft is slidably connected inside the three sliding grooves. Each of the three sliding grooves is provided with a return spring, and the upper and lower ends of the three return springs are respectively fixed to the corresponding sliding groove and the limiting shaft.

[0018] Preferably, the slide groove, the return spring, and the limiting shaft are each arranged in two sets inside the corresponding aluminum profile limiting block.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This high-precision cutting device for aluminum profile processing uses an aluminum profile limiting plate that slides along an aluminum profile support plate. The limiting plate can fit tightly against both sides of the aluminum profile, forming a rigid lateral clamping, which prevents the aluminum profile from shifting laterally due to the radial impact force of the cutting blade during cutting. At the same time, the limiting block limits the upper end of the aluminum profile, and the two aluminum profile support plates form a stable bottom support for the aluminum profile. The synergistic effect of the limiting plate, limiting block, and support plates significantly improves the fit between the aluminum profile and the limiting structure, distributes the clamping force evenly, controls the minute displacement of the aluminum profile during cutting, improves production efficiency, effectively avoids skewing and wavy lines on the cut end face, and meets the high-precision requirements for the verticality of the aluminum profile end face in building curtain walls and electronic equipment frames.

[0021] 2. This high-precision cutting device for aluminum profile processing features two staggered cutting blades on the cutting frame, with the lowest point of the upper blade higher than the highest point of the lower blade. During cutting, the upper blade first performs a non-through cut on the upper end of the aluminum profile, initially forming a cutting groove and dispersing the cutting stress of the lower blade. Subsequently, the lower blade performs a secondary cut on the uncut area, ultimately completely cutting off the aluminum profile. This reduces localized cutting heat and prevents deformation of the aluminum profile due to high temperatures, making it particularly suitable for cutting thin-walled, soft aluminum profiles and improving production efficiency. At the same time, the dispersed cutting force and heat reduce the wear rate of the cutting blades, extend their service life, and lower equipment maintenance costs. Attached Figure Description

[0031] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Please see Figure 1-7 This utility model provides a technical solution: a high-precision cutting device for aluminum profile processing, wherein the upper end of the base 1 is fixedly connected to the cutting table 2 to provide overall stable support for the device; the upper end of the base 1 is also fixedly connected to the cutting frame 3, which has an "F" shaped structure, and its left side is used to install cutting components, providing a fixed and working space for the cutting blade 13, avoiding collision and interference of aluminum profiles or components during cutting, and solving the problem of poor cutting stability caused by the loose structure of traditional cutting frames.

[0036] The lower left and right sides of the cutting table 2 are fixedly connected to the first guide frame 4 and the second guide frame 5, respectively. The front end of the first guide frame 4 is fixedly connected to the first drive motor 6. The output end of the first drive motor 6 is coaxially fixed with the threaded rod 7. The threaded rod 7 is rotatably connected to the first guide frame 4. The threaded rod 7 is threadedly fitted with the first slide table 8, and the first slide table 8 is slidably connected to the first guide frame 4. This structure drives the threaded rod to rotate through the motor, which drives the first slide table 8 to slide smoothly, replacing manual pushing and avoiding cutting deviation caused by uneven feed speed.

[0037] The interior of the second guide frame 5 is fixedly connected to the guide rod 9, and the surface of the guide rod 9 is slidably sleeved with the second slide table 10. The second slide table 10 is slidably connected to the second guide frame 5. The first slide table 8 and the second slide table 10 are both fixed to the slide frame 11 by bolts, and a slot 15 can be opened on the inner side of the slide frame 11 to form a double fixation of "slotting and bolting". This solves the problem that simple bolt connection is prone to stripping after long-term use, which causes the slide frame 11 to deviate from the feed, and improves the stability of the drive feed.

[0038] The interior of the carriage 11 is fixedly connected to two first electric telescopic rods 16. The output end of the first electric telescopic rods 16 is fixedly connected to the aluminum profile limiting plate 17. The aluminum profile limiting plate 17 is slidably connected to the aluminum profile support plate 21. The two aluminum profile support plates 21 are fixedly connected to the inner side of the carriage 11 and slidably connected to the cutting table 2. The surface of the aluminum profile support plate 21 is provided with a scale groove, which can help read the cutting length and solve the problem of length deviation caused by traditional positioning relying on visual estimation. The aluminum profile limiting plate 17 can rigidly clamp the two sides of the aluminum profile to avoid lateral displacement.

[0039] The left and right sides of the slide 11 are fixedly connected to the connecting frame 18. The interior of the connecting frame 18 is fixedly connected to the second electric telescopic rod 19. The output end of the second electric telescopic rod 19 is fixedly connected to the aluminum profile limiting block 20. Three sliding grooves 22 can be opened inside the aluminum profile limiting block 20. The limiting shaft 24 is slidably connected in the sliding groove 22. The return spring 23 is also fixed in the sliding groove 22. Traditional devices do not have an upper limit. This structure constrains the upper end of the aluminum profile through the aluminum profile limiting block 20, which solves the problem of the aluminum profile moving up and down during cutting. It is especially suitable for thin-walled and long strip aluminum profiles.

[0040] The surface of the cutting table 2 is provided with a guide groove 25, which can guide the aluminum profile to quickly align with the cutting path and reduce the positioning and adjustment time. The surface of the cutting table 2 is also provided with a groove 14, which provides clearance space for the lower cutting blade 13 to avoid collision between the cutting blade 13 and the cutting table 2, and collects cutting debris to ensure smooth cutting.

[0041] The left side of the cutting assembly cutting frame 3 is fixedly connected to two second drive motors 12, and the output end of the second drive motor 12 is fixedly connected to the cutting blade 13; the two cutting blades 13 are staggered vertically, and the lowest point of the upper cutting blade 13 is higher than the highest point of the lower cutting blade 13; this solves the problem of local overheating and deformation caused by a single cutting blade penetrating the aluminum profile at one time, and realizes multi-stage cutting to improve the cutting accuracy.

[0042] Working principle: The aluminum profile to be cut is placed on the surface of two aluminum profile support plates 21 above the cutting table 2. The two aluminum profile support plates 21 provide horizontal support for the aluminum profile, preventing positioning deviation caused by the aluminum profile sagging due to insufficient rigidity. At the same time, one end of the aluminum profile is pushed to slide along the guide groove 25 opened on the surface of the cutting table 2. The guide groove 25 guides the aluminum profile to quickly align with the preset path of the cutting component through the preset groove trajectory. The cutting benchmark can be initially determined without repeated adjustments, realizing rapid positioning of the cutting position.

[0043] Because the surface of the aluminum profile support plate 21 has graduated grooves, the operator can observe the alignment between the end of the aluminum profile and the graduated grooves on the surface of the aluminum profile support plate 21, accurately read and determine the cutting length, replacing the traditional positioning method of "visual estimation" or "extra measuring", controlling the positioning error to the minimum range, and laying the foundation for subsequent high-precision cutting.

[0044] The two first electric telescopic rods 16 fixed inside the slide 11 are activated. The output ends of the two first electric telescopic rods 16 synchronously push the corresponding aluminum profile limiting plates 17 to slide along the surface of the aluminum profile support plate 21. This continues until the inner walls of the two aluminum profile limiting plates 17 are tightly fitted with the left and right sides of the aluminum profile, and a uniform clamping force is applied. This achieves rigid lateral constraint on the aluminum profile, preventing lateral displacement of the aluminum profile due to the radial impact force of the cutting blade 13 during the cutting process, and ensuring the perpendicularity of the cutting end face.

[0045] The second electric telescopic rods 19 inside the connecting frames 18 fixed on the left and right sides of the slide 11 are started simultaneously. The output ends of the two second electric telescopic rods 19 drive the corresponding aluminum profile limiting blocks 20 to move vertically downward until the lower end surfaces of the two aluminum profile limiting blocks 20 are in close contact with the upper end surface of the aluminum profile and a preset pressure is applied, thus completing the vertical limiting constraint of the aluminum profile and preventing the aluminum profile from moving up and down due to vibration during cutting, thereby further improving the fixing stability of the aluminum profile.

[0046] The first drive motor 6, fixed at the front end of the first guide frame 4 above the cutting table 2 on the upper part of the base 1, drives the threaded rod 7, which is coaxially fixed with it, to rotate inside the first guide frame 4. Since the first slide 8, threadedly fitted on the surface of the threaded rod 7, slides in cooperation with the first guide frame 4, the rotation of the threaded rod 7 causes the first slide 8 to move along the length of the first guide frame 4 towards the cutting frame 3. Simultaneously, the second slide 10, slidably fitted on the surface of the guide rod 9 fixed inside the second guide frame 5 on the other side of the lower part of the cutting table 2, moves synchronously with the first slide 8. Finally, the slide 11 drives the aluminum profile fixed on it to smoothly approach the cutting blade 13 along a preset path, achieving uniform, linear feeding of the aluminum profile and avoiding feeding deviations caused by manual pushing or single drive.

[0047] When the aluminum profile is fed to the bottom of the cutting frame 3, the two second drive motors 12 installed on the left side of the cutting frame 3 are started. The output end of the second drive motor 12 drives the corresponding cutting blade 13 to rotate at high speed, performing multiple cuts:

[0048] The upper cutting blade 13 first contacts the upper end of the aluminum profile. Since the two cutting blades 13 are staggered, the upper cutting blade 13 only cuts the upper area of ​​the aluminum profile, initially forming a cutting groove to disperse the stress of subsequent cutting.

[0049] As the aluminum profile continues to feed, the lower cutting blade 13 contacts the lower end area of ​​the aluminum profile. Since the lower cutting blade 13 is located inside the groove 14 opened on the surface of the cutting table 2, the groove 14 provides cutting clearance space for the lower cutting blade 13. The lower cutting blade 13 performs secondary cutting on the area of ​​the aluminum profile that is not completely cut off, and finally completely cuts off the aluminum profile.

[0050] This "top-to-bottom" multi-stage cutting method avoids localized overheating caused by a single cutting blade penetrating the aluminum profile in one go; it reduces the deformation of the aluminum profile caused by high temperature, while also reducing the cutting resistance of the cutting blade 13, reducing burr generation, and significantly improving the cutting accuracy and cut quality of the aluminum profile.

[0051] After the aluminum profile is cut, the second drive motor 12 is turned off to stop the cutting blade 13 from rotating. At the same time, the first drive motor 6 is controlled to rotate in the opposite direction, driving the slide 11 and the cut aluminum profile to move away from the cutting frame 3 and return to the initial position. Subsequently, the first electric telescopic rod 16 and the second electric telescopic rod 19 are controlled to move in the opposite direction, driving the aluminum profile limiting plate 17 and the aluminum profile limiting block 20 to detach from the surface of the aluminum profile, releasing the limiting constraints. Finally, the operator takes out the cut aluminum profile, completing a single high-precision cutting process.

[0052] Furthermore, by sliding the aluminum profile limiting plate 17 along the aluminum profile support plate 21, the aluminum profile limiting plate 17 can be tightly fitted with both sides of the aluminum profile to form a rigid lateral clamping, preventing the aluminum profile from shifting laterally due to the radial impact force of the cutting blade 13 during cutting. At the same time, the aluminum profile limiting block 20 limits the upper end of the aluminum profile, and the two aluminum profile support plates 21 form a stable bottom support for the aluminum profile. The aluminum profile limiting plate 17, the aluminum profile limiting block 20, and the aluminum profile support plate 21 work together to significantly improve the fit between the aluminum profile and the limiting structure, distribute the clamping force evenly, control the small displacement of the aluminum profile during cutting, improve production efficiency, effectively avoid skewing and wavy patterns on the cut end face, and meet the high precision requirements of the verticality of the aluminum profile end face for building curtain walls and electronic equipment frames.

[0053] The two cutting blades 13 on the cutting frame 3 are staggered vertically, with the lowest point of the upper cutting blade 13 being higher than the highest point of the lower cutting blade 13. During cutting, the upper cutting blade 13 first performs a non-through cut on the upper end of the aluminum profile, initially forming a cutting groove and dispersing the cutting stress of the lower cutting blade 13. Subsequently, the lower cutting blade 13 performs a secondary cut on the uncut area, ultimately completely cutting off the aluminum profile. This reduces local cutting heat and prevents the aluminum profile from deforming due to high temperatures, making it particularly suitable for cutting thin-walled soft aluminum profiles and improving production efficiency. At the same time, the dispersed cutting force and heat can reduce the wear rate of the cutting blades 13, extend their service life, and reduce equipment maintenance costs.

[0054] Example 1: Connection reinforcement example with a slot 15 on the inner side of the carriage 11

[0055] A slot 15 is opened on the inner side of the slide 11. The shape of the slot 15 matches the end protrusions of the first slide 8 and the second slide 10. During assembly, the end of the first slide 8 is first inserted into the slot 15 on one side of the slide 11, and the end of the second slide 10 is inserted into the slot 15 on the other side of the slide 11. Then, the first slide 8 and the second slide 10 are fixed to the slide 11 with the original bolts, forming a dual connection structure of "slot-fitting and bolt fastening" to replace the traditional "simple bolt connection".

[0056] Heavy aluminum profiles are heavy, and when the first drive motor 6 drives the slide 11 to feed, the first slide 8 and the second slide 10 need to bear the huge thrust and torque transmitted by the slide 11. If they are only fixed by bolts, long-term use will easily cause stress concentration, resulting in bolt stripping and gaps in the connection surface between the first slide 8 and the slide 11, which will cause the slide 11 to deviate in feed and reduce the cutting accuracy.

[0057] The slot 15 can pre-position the first slide 8 and the second slide 10 to avoid misalignment between the first slide 8, the second slide 10 and the slide 11 during bolt installation, and ensure that the connecting surfaces of the first slide 8, the second slide 10 and the slide 11 are fully fitted, reducing stress concentration points.

[0058] The snap-fit ​​structure can share the torque and thrust borne by the bolt, improve the connection strength of the first slide 8, the second slide 10 and the carriage 11, and reduce the perpendicularity of the cutting end face; after the connection of "slot 15 and bolt", it is easy to improve the connection stability of the first slide 8, the second slide 10 and the carriage 11, and meet the high-precision assembly requirements of industrial machinery for aluminum profiles.

[0059] Example 2: Adaptive limiting embodiment of aluminum profile limiting block 20 with added sliding groove 22 + return spring 23 + limiting shaft 24

[0060] Three sliding grooves 22 are evenly opened along the length direction inside the aluminum profile limiting block 20; a limiting shaft 24 is slidably connected inside each sliding groove 22, and the lower end of the limiting shaft 24 extends out of the aluminum profile limiting block 20 to contact the upper end of the aluminum profile; a return spring 23 is also provided inside each sliding groove 22, the upper end of the return spring 23 is fixed to the top of the sliding groove 22, and the lower end is fixed to the upper end of the limiting shaft 24, forming a "spring-driven, shaft-adaptive" limiting structure, replacing the traditional "rigid planar aluminum profile limiting block 20".

[0061] When the second electric telescopic rod 19 drives the aluminum profile limiting block 20 to press down, the limiting shaft 24 will first contact the upper end of the aluminum profile. As the aluminum profile limiting block 20 continues to move down, the return spring 23 will automatically compress or extend according to the curvature of the upper end of the aluminum profile, so that the lower ends of the three limiting shafts 24 respectively fit with different curvature points of the upper end of the aluminum profile, forming a "three-point adaptive positioning" and increasing the limiting contact area.

[0062] Adaptive bonding can prevent deformation of aluminum profiles caused by excessive local stress, reduce the vertical movement of aluminum profiles during cutting, control the perpendicularity error of the cut end face, reduce burr height, and improve production efficiency.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
