Description

Technical Field

[0001] This utility model relates to the field of building material processing equipment technology, specifically a multi-angle cutting device for building profiles. Background Technology

[0002] In the field of building material processing technology, the cutting of building profiles (such as square tubes, angle steel, channel steel, etc.) is a common process before construction or during assembly. In order to meet the needs of complex building structures, it is often necessary to cut the profiles into specific angles, such as for mitering or splicing.

[0003] Currently, most common profile cutting devices on the market are simple cutting tables or fixed cutting machines. These devices typically have the following shortcomings: First, their cutting angles are relatively limited, mostly only capable of 90° vertical cutting or cutting at a few fixed angles. When cutting at other arbitrary angles is required, the operation is extremely inconvenient and cannot meet the requirements of multi-angle and complex processing. Second, existing devices often require multiple bolts to be tightened one by one when clamping profiles, which is a cumbersome and time-consuming process that cannot achieve rapid positioning and clamping of the profiles, affecting processing efficiency. In addition, they lack angle adjustment mechanisms, making it difficult to quickly adjust the angle of the profile to be cut, which needs further improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-angle cutting device for building profiles, which has the advantages of flexible and adjustable cutting angle and quick and convenient profile clamping, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-angle cutting device for building profiles includes a base plate, a frame fixed to the upper end of the base plate, a fixed plate fixed to the upper end of the frame, a cutting mechanism for cutting mounted on the frame, a fixed frame fixed to the upper end of the base plate, and a multi-angle adjustment mechanism mounted on the fixed frame. The multi-angle adjustment mechanism includes two U-shaped blocks fixed to the end of the fixed frame away from the fixed plate, a ramp rotatably mounted on both sides of the inner wall of one of the U-shaped blocks, and a second electric cylinder hinged to the other U-shaped block. The output end of the second electric cylinder is hinged to the lower end of the ramp. A limiting mechanism for limiting the position is provided at the upper end of the inclined platform; A limiting groove is provided through the upper end of the fixed plate, and the cutting end of the cutting mechanism is located inside the limiting groove; The frame is equipped with a dust collection mechanism for collecting dust during the cutting process, and the end of the U-shaped block away from the fixed frame is equipped with a clamping mechanism for positioning the profile placed inside the two U-shaped blocks.

[0006] Preferably, the limiting mechanism includes multiple slots that pass through the upper inclined surface of the inclined platform, two inserts inserted into the inner wall of the slots, and a limiting block fixed to one end of the two inserts that is far apart from each other. The lower end of the limiting block is in contact with the upper inclined surface of the inclined platform.

[0007] It is worth noting that the limiting mechanism achieves adjustable limiting through the cooperation of slots and blocks, which can adapt to building profiles of different sizes and shapes, ensuring that the profiles remain stable during the cutting process and preventing slippage or displacement. The limiting block fits against the upper inclined surface of the ramp, providing uniform support and enhancing the reliability of the limiting.

[0008] Preferably, the cutting mechanism includes a base fixed to the upper end of the frame, a first electric cylinder fixed to the upper end of the base, two guide rails fixed to the upper end of the base, a slider slidably disposed on the side wall of the guide rail, a bearing plate fixed to the upper end of the two sliders, a first mounting seat and a second mounting seat fixed to the upper end of the bearing plate, a motor fixed to the upper end of the first mounting seat, and a cutting disc rotatably mounted on the second mounting seat. The cutting disc is located inside the limiting groove. The output shaft of the motor is fixedly connected to a first synchronous pulley. The rotating shaft of the cutting disc passes through the second mounting seat and is fixedly connected to a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are rotatably connected by a transmission belt. A fixed plate is fixedly connected to the lower end of the bearing plate, and the output shaft of the first electric cylinder is fixedly connected to the fixed plate.

[0009] It is worth noting that the cutting mechanism adopts an electric cylinder and guide rail slider system, which realizes the precise linear motion of the cutting disc, ensuring the controllability of cutting depth and position. The synchronous belt pulley transmission structure ensures the stability of the high-speed rotation of the cutting disc and the efficiency of power transmission, reduces vibration and noise, and extends the service life of the equipment. The first electric cylinder pushes the bearing plate through the fixed plate, making the cutting process smooth and responsive, improving cutting accuracy and repeatability.

[0010] Preferably, the dust collection mechanism includes a dust collection body fixed to the frame, a first trough opened at the upper end of the dust collection body, and a second trough opened on one side of the dust collection body. A second collection box is placed at the upper end of the frame, and the second collection box is located below the second trough.

[0011] It is worth noting that in this preferred embodiment, the dust collection mechanism effectively captures the dust and debris generated during the cutting process through the dust collection body, the first trough, and the second trough structure. The first trough and the second trough can guide the dust into the second collection box, which facilitates the rapid collection of some of the dust generated during cutting.

[0012] Preferably, the ramp is a triangular structure, and the sides of the ramp are acute triangles.

[0013] It is worth noting that the inclined platform adopts a triangular structure with acute-angled triangles on the sides, which provides high structural strength and stability, reduces material usage and weight, and facilitates installation and adjustment.

[0014] Preferably, the two sides of the inclined platform and the inner walls of the two sides of the U-shaped block are fitted together.

[0015] It is worth noting that in this preferred design, the two sides of the inclined platform are closely fitted to the inner wall of the U-shaped block, ensuring the stability and alignment accuracy of the inclined platform during rotation, effectively reducing the risk of swaying and offset. This fitted design makes the pushing and pulling action of the second electric cylinder more effective, achieving precise angle control.

[0016] Preferably, a groove is provided in the middle of the upper end of the inclined platform, and the middle of the groove corresponds to the limiting groove.

[0017] It is worth noting that in this preferred solution, the groove in the middle of the upper part of the inclined platform corresponds to the limiting groove on the fixed plate, allowing the cutting plate of the cutting mechanism to pass smoothly, avoiding interference with the inclined platform during the cutting process, and ensuring the continuity and integrity of the cutting. This design optimizes the spatial layout and improves the cutting efficiency, and is especially suitable for long profiles or multi-point cutting tasks. The groove also facilitates the falling of debris and reduces the risk of accumulation.

[0018] Preferably, a first collection box is placed on the upper part of the base plate, and the first collection box is located below the two U-shaped blocks.

[0019] It is worth noting that in this preferred solution, the first collection box is located below the U-shaped block on the base plate, which effectively collects the debris and dust falling from the inclined platform and cutting area, realizing centralized management of waste materials and reducing cleaning frequency and maintenance costs.

[0020] Preferably, the clamping mechanism includes an internally threaded cylinder fixed to the end of the U-shaped block away from the fixed frame and a bolt threaded onto the inner wall of the internally threaded cylinder. The end of the U-shaped block away from the fixed frame has a through hole, and the inner wall of the through hole is flush with the inner wall of the internally threaded cylinder.

[0021] It is worth noting that in this preferred embodiment, the clamping mechanism achieves rapid clamping and fixing of the profile through the cooperation of the internal threaded cylinder and bolts, preventing it from moving or rotating during the cutting process, ensuring the accuracy of the cutting position. The design of the through hole being flush with the inner wall of the internal threaded cylinder facilitates the smooth entry and exit of the bolt, reduces friction and wear, and improves the reliability and service life of the clamping. The mechanism has a simple structure and is easy to operate, allowing users to adjust the clamping force as needed. It is suitable for profiles of different sizes and enhances safety and stability.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The second electric cylinder in the multi-angle adjustment mechanism is connected to the inclined platform by a hinge. When the second electric cylinder extends or retracts, it drives the inclined platform to rotate around one of the U-shaped blocks, thereby changing the tilt angle of the inclined platform and realizing stepless adjustment of the angle to be cut of the profile. The inclined platform adopts a triangular body structure with acute-angled triangles on the sides, which provides stable support and ensures the accuracy and reliability of angle adjustment. It can meet the cutting needs of multiple angles and overcome the limitation of existing devices that can only perform fixed-angle cutting. 2. The limiting mechanism, through the cooperation of slots and inserts, allows users to quickly adjust the position of the limiting block according to the size and shape of the profile, thus achieving the initial positioning of the profile. The clamping mechanism, through the cooperation of the internal threaded cylinder and bolts, passes through the through hole on the U-shaped block and directly clamps the profile, eliminating the need for multiple bolts to be tightened one by one, simplifying the clamping process and significantly improving clamping efficiency. 3. The cutting mechanism drives the support plate to move along the guide rail through the first electric cylinder, which drives the cutting disc to move in a straight line, ensuring that the cutting depth and position are controllable. The synchronous belt pulley transmission ensures the stability of the high-speed rotation of the cutting disc, reduces vibration and noise, and improves the cutting quality. 4. The dust collection mechanism captures the dust and debris generated during the cutting process through the dust collection body, the first tank and the second tank, and guides them to the second collection box. At the same time, the first collection box set on the bottom plate is located below the U-shaped block, which effectively collects the debris falling from the inclined platform, realizing the centralized treatment of waste and maintaining a clean working environment.

Detailed Implementation

[0025] 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.

[0026] To address the problems of limited cutting angles, cumbersome profile clamping processes, and lack of rapid angle adjustment mechanisms in existing technologies, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-6 ; A multi-angle cutting device for building profiles includes a base plate 1, a frame 2 fixed to the upper end of the base plate 1, a fixed plate 3 fixed to the upper end of the frame 2, a cutting mechanism 4 set on the frame 2 for cutting, a fixed frame 5 fixed to the upper end of the base plate 1, and a multi-angle adjustment mechanism set on the fixed frame 5. The multi-angle adjustment mechanism includes two U-shaped blocks 6 fixed to one end of the fixed frame 5 away from the fixed plate 3, a ramp 7 rotatably mounted on both sides of the inner wall of one of the U-shaped blocks 6, and a second electric cylinder 10 hinged to the other U-shaped block 6. The output end of the second electric cylinder 10 is hinged to the lower end of the ramp 7. The upper end of the inclined platform 7 is equipped with a limiting mechanism for limiting the position; A limiting groove 16 is formed through the upper end of the fixed plate 3, and the cutting end of the cutting mechanism 4 is located inside the limiting groove 16; The frame 2 is equipped with a dust collection mechanism for collecting dust during the cutting process of the cutting mechanism 4, and the end of the U-shaped block 6 away from the fixed frame 5 is equipped with a clamping mechanism for positioning the profile placed in the two U-shaped blocks 6.

[0027] In use, the profile is placed on the upper end of the inclined platform 7, and the clamping mechanism is used to press the profile against the inner wall of the U-shaped block 6. Then, the limiting mechanism is used to limit the profile. When it is necessary to adjust the placement angle of the profile, the second electric cylinder 10 is activated to extend and retract its output shaft from the cylinder body, which can adjust the angle of the inclined platform 7, thereby realizing the rapid adjustment of the placement angle of the profile. Then, the cutting mechanism 4 is activated to cut the limited profile, thus realizing the rapid cutting of the profile at a specific angle.

[0028] In this embodiment, specifically: the limiting mechanism includes multiple slots 9 that pass through the upper inclined surface of the inclined platform 7, two inserts 11 inserted into the inner wall of the slots 9, and a limiting block 12 fixed to one end of the two inserts 11 that is far away from each other. The lower end of the limiting block 12 is in contact with the upper inclined surface of the inclined platform 7.

[0029] In this embodiment, specifically: the cutting mechanism 4 includes a base 41 fixed to the upper end of the frame 2, a first electric cylinder 42 fixed to the upper end of the base 41, two guide rails 43 fixed to the upper end of the base 41, a slider 44 slidably disposed on the side wall of the guide rail 43, a support plate fixed to the upper end of the two sliders 44, a first mounting seat 45 and a second mounting seat 46 fixed to the upper end of the support plate, a motor 47 fixed to the upper end of the first mounting seat 45, and a cutting disc 48 rotatably mounted on the second mounting seat 46. The cutting disc 48 is located inside the limiting groove 16. The output shaft of the motor 47 is fixedly connected to a first synchronous pulley. The rotating shaft of the cutting disc 48 passes through the second mounting seat 46 and is fixedly connected to a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are rotatably connected through a transmission belt. A fixed plate is fixedly connected to the lower end of the support plate, and the output shaft of the first electric cylinder 42 is fixedly connected to the fixed plate.

[0030] In this embodiment, specifically: the dust collection mechanism includes a dust collection body 17 fixed to the frame 2, a first trough 18 opened at the upper end of the dust collection body 17, and a second trough 19 opened on one side of the dust collection body 17. A second collection box 20 is placed at the upper end of the frame 2, and the second collection box 20 is located below the second trough 19.

[0031] In this embodiment, specifically: the inclined platform 7 is a triangular structure, and the side of the inclined platform 7 is an acute triangle.

[0032] In this embodiment, specifically: the two sides of the inclined platform 7 and the inner walls of the two sides of the U-shaped block 6 are fitted together.

[0033] In this embodiment, specifically: a groove 8 is provided in the middle of the upper end of the inclined platform 7, and the middle of the groove 8 corresponds to the limiting groove 16.

[0034] In this embodiment, specifically: a first collection box 15 is placed on the upper end of the base plate 1, and the first collection box 15 is located below the two U-shaped blocks 6.

[0035] In this embodiment, specifically: the clamping mechanism includes an internally threaded cylinder 13 fixed to the end of the U-shaped block 6 away from the fixed frame 5 and a bolt 14 threadedly installed on the inner wall of the internally threaded cylinder 13. The end of the U-shaped block 6 away from the fixed frame 5 has a through hole, and the inner wall of the through hole is flush with the inner wall of the internally threaded cylinder 13.

[0036] This clamping mechanism achieves rapid clamping and fixing of the profile through the threaded engagement of the internal threaded cylinder 13 and the bolt 14. Its structure is simple and reliable. During operation, only rotating the bolt 14 is needed to generate a stable clamping force. The optimized design of the through hole being flush with the inner wall of the internal threaded cylinder 13 makes the bolt 14 move in and out smoothly, reducing friction and wear and extending its service life. This device can effectively restrict the movement and rotation of the profile during the cutting process, ensuring the accuracy of the cutting position and significantly improving the clamping efficiency.

[0037] To achieve automated control, the cutting device of this utility model may further include a controller (not shown in the figure). The controller may preferably be a PLC (Programmable Logic Controller) or a microprocessor, which is electrically connected to the first electric cylinder 42, the second electric cylinder 10 and the motor 47 via a line or wireless means. The controller stores a control program to coordinate the action sequence and logic of each actuator. The operator can set the cutting angle and start or stop the cutting process through a human-machine interface (such as a touch screen or button panel) connected to the controller.

[0038] Working principle: During operation, the building profile to be cut is first placed on the upper inclined surface of the inclined platform 7. According to the size of the profile and the cutting requirements, the appropriate slot 9 is selected and the insert block 11 is inserted, so that the limiting block 12 is close to the side of the profile for initial positioning. Then, the bolt 14 of the clamping mechanism is rotated to push it inward, and the end of the bolt 14 is directly pressed to the end of the profile to achieve quick fixation. When the cutting angle needs to be adjusted, the second electric cylinder 10 of the multi-angle adjustment mechanism is activated, causing its output shaft to extend and retract, driving the inclined table 7 to rotate around the rotation fulcrum of the U-shaped block 6 through the hinge point, thereby causing the profile fixed on the inclined table 7 to tilt synchronously to the required angle. After clamping, the cutting program is started by the controller. The controller first starts the motor 47, which drives the cutting disc 48 to rotate at high speed through the transmission system. Then, the controller drives the first electric cylinder 42 to push the fixed plate, which drives the bearing plate to move downward along the guide rail 43, so that the rotating cutting disc 48 can accurately cut the profile through the limiting groove 16 of the fixed disc 3 and the groove 8 of the inclined table 7. After the cutting is completed, the first electric cylinder 42 automatically retracts and the motor 47 stops running. During the cutting process, some of the debris and dust fall directly into the first collection box 15 on the base plate 1, while the other part is captured by the dust collector 17 through the first trough 18 and guided through the second trough 19 to the second collection box 20, thus realizing the centralized collection and treatment of waste.
