Technical Field

[0001] This application relates to the field of metal cutting equipment technology, and in particular to a profile cutting device and a profile cutting method. Background Technology

[0002] Profiles (such as I-beams, angle steel, and channel steel) are key structural components widely used in construction, machinery, bridges, and shipbuilding. Their cutting accuracy and efficiency directly affect project quality and construction progress. Currently, profile cutting relies heavily on manual labor, which is time-consuming and inefficient. Furthermore, profile cutting depends on operator experience, and issues such as tilting and burrs on the cut surface can lead to errors in subsequent welding or assembly. Manual operation also presents challenges such as high labor intensity, excessively high temperatures, and significant safety hazards (e.g., grinding wheel splashes and dust inhalation).

The locking mechanism includes a pin. One end of the pin is fixedly connected to the frame, and the other end of the pin is movable to insert into or abut against the floating plate, so that the floating plate and the frame are locked together.

[0008] In some embodiments of this application, the floating plate is provided with a plug groove, the plug groove has an opening on the outer edge of the floating plate, and the pin can be rotated along one end so that the other end is inserted into the plug groove from the opening.

[0011] The moving module further includes a second guide rail, which is disposed in the first movable mechanism and is arranged along a first direction. The mounting platform is connected to the first movable mechanism and the second guide rail, and the second guide rail is used to guide the mounting platform to move along a second direction.

[0012] In some embodiments of this application, the rotating mechanism includes a rotating drive, a transmission belt, and a rotating seat. The rotating drive and the rotating seat are disposed at both ends of the mounting platform along a first direction. The cutting mechanism is connected to the rotating seat. The transmission belt is sleeved on the outer periphery of the rotating seat and the output end of the rotating drive. The transmission belt is used to drive the rotating seat to rotate under the drive of the rotating drive, so as to make the cutting device rotate.

[0013] In some embodiments of this application, the cutting module includes multiple cover plates, which are disposed on the mounting platform and enclose a receiving space.

This means the mounting platform can move the cutting module to any position on the movable plane, thus meeting the cutting requirements of the steel profile. The rotating mechanism drives the cutting mechanism to rotate, ensuring that the cutting mechanism maintains its output direction towards the profile while moving around its outer contour, achieving the cutting purpose. The cooperation between the moving module and the rotating mechanism allows the cutting mechanism to move along the steel profile's trajectory, achieving accurate and efficient cutting. Since the moving trajectory of the mounting platform is within the movable plane, and the movable plane is perpendicular to the length direction of the profile, the cutting device can cut the steel in a plane perpendicular to the length direction of the profile. During the cutting process, the moving module and the cutting module can be used to complete the process automatically, thereby improving the degree of automation in cutting. Compared with manual cutting, this helps to improve the accuracy and efficiency of cutting, and avoids the safety hazards to personnel that exist in manual cutting operations.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] In this application, the profile can be aluminum profile, steel (section steel), etc. Taking steel as an example, the steel can have different cross-sectional shapes, such as I-beams (H-beams), angle steel, channel steel, C-beams, Z-beams, etc., and the steel is usually set in a rod-like form, that is, the extension direction of the steel is the length direction of the steel. When cutting the steel, the steel is cut along a direction perpendicular to its length.

[0038] Please see Figures 1 to 3 as well as Figure 6 The first aspect of this application proposes a profile cutting device 1000 (hereinafter referred to as cutting device 1000), which includes a support module 100, a moving module 200 and a cutting module 300. The support module 100 includes a clamping structure 110 for clamping and fixing the profile to be cut; the moving module 200 includes a first movable mechanism 210, a second movable mechanism 220, and a mounting platform 230. The mounting platform 230 is mounted on the first movable mechanism 210. The first movable mechanism 210 drives the mounting platform 230 to move along a first direction. The first movable mechanism 210 is mounted on the second movable mechanism 220. The second movable mechanism 220 drives the first movable mechanism 210 to move along a second direction, so that the mounting platform 230 can move along a movable plane perpendicular to the length direction of the profile. The first direction and the second direction are set at an angle; the cutting module 300 includes a cutting mechanism 310 and a rotating mechanism 320. The rotating mechanism 320 is disposed on the mounting platform 230 and is used to drive the cutting mechanism 310 to rotate. The moving module 200 and the rotating mechanism 320 drive the cutting mechanism 310 to cut the profile along the contour of the profile.

[0039] In this embodiment, the clamping structure 110 fixes the relative positions of the profile to be cut and the cutting device 1000, ensuring that there is no displacement between the profile and the support module 100 of the cutting device 100 during the cutting process, thus improving cutting accuracy. The moving module 200 includes a first movable mechanism 210 and a second movable mechanism 220, enabling the mounting platform 230 to move in the first and second directions. This means the mounting platform 230 can move the cutting module 300 to any position on the movable plane, thus meeting the cutting requirements of the steel profile. The rotating mechanism 320 drives the cutting mechanism 310 to rotate, ensuring that the output direction of the cutting mechanism 310 remains facing the profile as it moves around the outer contour of the profile, achieving the cutting objective. The cooperation between the moving module 200 and the rotating mechanism 320 enables the cutting mechanism 310 to move along the contour of the steel profile. For example, the steel profile can be an H-beam, angle steel, channel steel, C-beam, Z-beam, etc. Different steel profiles have different cross-sectional shapes. Therefore, the cutting mechanism 310 can move according to the cross-sectional shape of the steel profile, achieving accurate and efficient cutting. Since the moving trajectory of the mounting platform 230 is within the moving plane, and the moving plane is perpendicular to the length direction of the profile, the cutting device 1000 can cut the steel 2000 in a plane perpendicular to the length direction of the profile. During the cutting process, the moving module 200 and the cutting module 300 can automatically complete the process, thereby improving the degree of automation. Compared with manual cutting, this helps to improve the accuracy and efficiency of cutting and avoids the safety hazards to personnel present during manual cutting operations.

[0040] Optionally, the mounting platform 230 can be a mounting structure other than the first movable mechanism 210, used to support the movement of the cutting module 300 to achieve cutting. Alternatively, the mounting platform 230 can also be formed by the movable output end of the first movable mechanism 210. That is, the first movable mechanism 210 can be, for example, a robotic arm, a motor, or other structure, and has a movable output end to achieve movement along a first direction. Therefore, the movable output end of the first movable mechanism 210 can be directly formed as the mounting platform 230, and the cutting module 300 can be connected to the output end of the first movable mechanism 210.

[0041] In some embodiments, the support module 100 further includes a floating plate 120, with the clamping structure 110 and the moving module 200 respectively mounted on two opposing surfaces of the floating plate 120. By mounting the clamping structure 110 and the moving module 200 on the opposing surfaces of the floating plate 120, the moving module 200 can be connected to the support module 100, resulting in a more compact assembled structure. This also avoids interference between the clamping structure 110 and the moving module 200 during operation, improving their independence and reliability. The clamping structure 110 includes a clamping drive 111 and two clamping arms 112. The two clamping arms 112 are rotatably connected to the floating plate 120. The clamping drive 111 drives the two clamping arms 112 to move closer together or open apart to clamp or release the profile. The driving action of the clamping drive 111 enables the automatic rotation of the clamping arms 112, thereby clamping or releasing the profile. Before cutting, the clamping drive 111 drives the two clamping arms 112 to rotate and move closer to each other in one direction to clamp the steel. After cutting, the clamping drive 111 drives the two clamping arms 112 to rotate and move away from each other in the other direction to release the steel.

[0042] Optionally, the clamping drive 111 can be a power component such as a motor or cylinder, and its output end can extend or retract in a straight line.

[0043] In some embodiments, the clamping structure 110 further includes two jaws 113 for clamping the profile. The two jaws 113 are respectively connected to one end of two clamping arms 112, and the other end of the two clamping arms 112 is connected to the output end of the clamping drive member 111. The clamping arms 112 and the jaws 113 are rotatably connected, and the connection point serves as the fulcrum for the rotation of the clamping arms 112. When the output end of the clamping drive member 111 extends, it pushes the two clamping arms 112 to open up to each other, and the clamping arms 112 drive the jaws 113 to open up to each other. When the output end of the clamping drive member 111 retracts, it pulls the two clamping arms 112 closer to each other, thereby causing the jaws 113 to retract to each other.

[0044] Taking an I-beam as an example, the jaw 113 can clamp onto the flange of the I-beam.

[0045] In actual cutting scenarios, the steel 2000 can be placed vertically or horizontally. For example, the steel 2000 is inserted vertically into the ground, the cutting device 1000 is close to the steel 2000, and the cutting mechanism 310 cuts the steel 2000 in a movable plane parallel to the horizontal plane. When the steel 2000 is set horizontally, such as when the steel 2000 is erected horizontally on a storage rack or support frame, the movable plane is set vertically, and the cutting mechanism 310 cuts the steel 2000 in a vertical plane.

[0046] In some embodiments, the profile cutting device 1000 further includes a frame 410 and a locking mechanism. The frame 410 is movable to approach or move away from the profile to be cut. The support module 100 also includes a sliding mechanism 130. The sliding mechanism 130 and the clamping structure 110 are both disposed on the bottom surface of the floating plate 120. The floating plate 120 is slidably connected to the frame 410 through the sliding mechanism 130. The floating plate 120 is used to drive the clamping structure 110 closer to the profile. The locking mechanism includes a pin 421. One end of the pin 421 is fixedly connected to the frame 410, and the other end of the pin 421 is movable to insert into or abut against the floating plate 120, so that the floating plate 120 and the frame 410 are locked together. By setting the frame 410, the entire cutting device 1000 can be moved flexibly, and can be moved to the vicinity of the steel 2000 before cutting. After cutting, the frame 410 is moved away from the steel 2000 and moved closer to another steel 2000 to continue cutting. On the one hand, compared to moving the steel 2000, the mobile cutting device 1000 offers greater feasibility and flexibility. Furthermore, the steel 2000 used in construction is typically large and heavy. Therefore, using a fixed steel 2000 and a mobile cutting device 1000 offers lower operational difficulty and higher safety compared to moving the steel 2000, thus improving the feasibility and convenience of the cutting operation. On the other hand, it also helps improve the efficiency of cutting the steel 2000. The locking mechanism secures the relative position between the floating plate 120 and the frame 410, preventing the floating plate 120 from moving during the cutting process, thereby improving cutting accuracy. By employing a sliding connection between the frame 410 and the floating plate 120, multi-level positioning for cutting the steel 2000 can be achieved. Specifically, moving the frame 410 close to the steel 2000 quickly achieves initial positioning of the cutting device 1000 and the steel 2000. Next, the clamping structure 110 on the floating plate 120 extends and clamps the steel 2000, fixing the cutting device 1000 and the steel 2000 together, achieving the second level of positioning. Furthermore, sliding the floating plate 120 on the frame 410 closer to the steel 2000 and fixing it to the frame 410 using the locking mechanism's pin 421 allows the floating plate 120 to drive the moving module 200 and the cutting module 300 further closer to the steel 2000, achieving the third level of positioning. In an alternative embodiment, the steps of moving the floating plate 120 and the clamping structure 110 extending and clamping the steel 2000 can be interchanged. By using a multi-level positioning scheme to determine the relative positional relationship between the cutting device 1000 and the steel 2000, positioning accuracy can be improved from coarse to fine, which helps to improve the positioning efficiency and the cutting accuracy of the steel 2000.

[0047] In some embodiments, the floating plate 120 is provided with a insertion groove 121, and the insertion groove 121 has an opening 1211 on the outer edge of the floating plate 120. The pin 421 can be rotated along one end so that the other end is inserted into the insertion groove 121 through the opening 1211. By using the insertion engagement of the pin 421 and the insertion groove 121, the locking stability and reliability of the pin 421 can be improved. By using the opening 1211 formed on the outer edge of the floating plate 120 by the insertion groove 121, the pin 421 can easily enter or leave through the opening 1211, reducing the difficulty of inserting the pin 421.

[0048] In some embodiments, the frame 410 includes a frame 411 and a pulley 412. The pulley 412 is mounted on the bottom surface of the frame 411, and the top surface of the frame 411 is provided with a sliding groove 4111. The sliding mechanism 130 includes a ball seat 131 and a ball 132. The ball 132 is housed in the ball seat 131, with a portion protruding from the ball. The ball seat 131 is mounted on the bottom surface of the floating plate 120, and the ball 132 is slidably disposed in the sliding groove 4111. Utilizing the rolling action of the ball 132, a sliding connection between the floating plate 120 and the frame 411 can be achieved. Furthermore, two-dimensional adjustment of the floating plate 120 at any position on the plane can be realized, thereby reducing the difficulty of adjusting the position of the floating plate 120 and improving the convenience and accuracy of positioning operations. The sliding groove 4111 can constrain the movement range of the ball 132, limiting the movable range of the ball 132 within the sliding groove 4111, thereby limiting the movement range of the floating plate 120. By utilizing the pulley 412, the frame 410 can move freely on the ground, reducing the difficulty of pushing the frame 410.

[0049] Optionally, the frame 410 may also be provided with a handlebar 413, which is attached to the frame 411 for pushing the frame 410 to move.

[0050] Alternatively, in other examples, the cutting device 1000 can also be installed in other auxiliary devices to cut the steel 2000 above the ground, such as at a high altitude. For example, a corresponding track can be set at the location where the steel 2000 needs to be cut, and the frame 410 or floating plate 120 of the cutting device 1000 can be set on the track. In this way, the cutting device 1000 can be moved to the target position to clamp, fix and cut the steel 2000.

[0051] Therefore, in some embodiments, please refer to Figure 7 The steel 2000 is set horizontally and is erected on the support frame in the horizontal direction. At this time, the cutting device 1000 cuts the steel 2000 in the vertical plane, that is, the movable plane is set vertically at this time.

[0052] It is understandable that the moving module 200, cutting module 300, and support module 100 can achieve the functions of positioning, clamping, fixing, and cutting the steel 2000, and can selectively connect with the frame 410 and locking mechanism. By utilizing the separation and reconfiguration of the modules, different cutting scenarios can be achieved. When it is necessary to cut the steel 2000 at a position near the ground, the moving module 200, cutting module 300, and support module 100 can be installed on the frame 410, and the locking mechanism can also be set on the frame 410 to lock the frame 410 and the floating plate 120 in the support module 100. When it is necessary to cut the steel 2000 at a high position, the frame 410 and other structures can be removed, and the moving module 200, cutting module 300, and support module 100 can be connected to high-altitude auxiliary equipment (such as a track). The movement of the track can then drive the cutting device 1000 to the target position. Furthermore, the orientation of the support module 100 can be flexibly adjusted according to the orientation of the steel 2000 (e.g., vertical or horizontal), thereby adjusting the orientation of the movable plane and ensuring that the movable plane is perpendicular to the length direction of the steel 2000. This modular design helps improve the adaptability and versatility of the cutting device 1000, meeting the cutting needs of various scenarios.

[0053] In some embodiments, the moving module 200 further includes a first guide rail 240, which is spaced apart from the second movable mechanism 220 on the floating plate 120 of the support module 100. The first guide rail 240 is arranged along a second direction, and the first movable mechanism 210 is connected to the second movable mechanism 220 and the first guide rail 240. The first guide rail 240 is used to guide the first movable mechanism 210 to move along the second direction. By setting the first guide rail 240, it can not only guide the first movable mechanism 210 during movement, but also support the first movable mechanism 210, distributing the weight of the first movable mechanism 210 to the first guide rail 240 and the second movable mechanism 220, thereby improving the stability and reliability of the first movable mechanism 210 during movement.

[0054] In some embodiments, the moving module 200 further includes a second guide rail 250, which is disposed in the first movable mechanism 210 and is arranged along a first direction. The mounting platform 230 is connected to the first movable mechanism 210 and the second guide rail 250, and the second guide rail 250 is used to guide the mounting platform 230 to move along a second direction. Similarly, the second guide rail 250 can provide guidance and distribute gravity for the mounting platform 230, improving the stability of the mounting platform 230 during movement, thereby improving the stability and cutting accuracy of the cutting module 300.

[0055] Optionally, taking the first movable mechanism 210 as an example, the first movable mechanism 210 can employ a combination of a motor and a screw. A slider is mounted on the screw for connection to the mounting platform 230. The motor drives the screw to rotate, thereby causing the slider to move linearly, thus achieving linear drive of the mounting platform 230. The second movable mechanism 220 can be configured in the same way as the first movable mechanism 210. Of course, in other examples, the first movable mechanism 210 and the second movable mechanism 220 can also be structures such as cylinders; no specific limitations are made here.

[0056] In some embodiments, please combine Figure 4 and Figure 5 The rotating mechanism 320 includes a rotating drive 321, a transmission belt 322, and a rotating base 323. The rotating drive 321 and the rotating base 323 are arranged at both ends of the mounting platform 230 along a first direction. The cutting mechanism 310 is connected to the rotating base 323. The transmission belt 322 is sleeved on the outer periphery of the output end of the rotating base 323 and the rotating drive 321. The transmission belt 322 is used to drive the rotating base 323 to rotate under the drive of the rotating drive 321, so that the cutting device 1000 rotates. By utilizing the transmission action of the transmission belt 322, the rotating drive 321 and the cutting mechanism 310 can be respectively arranged at both ends of the mounting platform 230. When the cutting mechanism 310 cuts the steel 2000, the rotating drive 321 can avoid obstructing the cutting mechanism 310, and interference between the rotating mechanism 320 and the steel 2000 can be avoided, thereby allowing more space for the cutting mechanism 310 to rotate and improving the convenience of the cutting mechanism 310's operation and its reliability.

[0057] In some embodiments, the cutting module 300 includes a plurality of cover plates 330, which are disposed on the mounting platform 230 and enclose a receiving space 331. The output end of the rotary drive 321 extends into the receiving space 331, and the transmission belt 322 is disposed within the receiving space 331. The rotary drive 321 and the cutting mechanism 310 are disposed on the cover plate 330 at the top of the receiving space 331. On the one hand, the cover plate 330 has a supporting force, which can be used to support the rotary drive 321, the rotating seat 323, and other structures, and can hide the transmission belt 322 within the receiving space 331, reducing the space occupied on the surface of the mounting bracket and making the structure of the cutting module 300 more compact. On the other hand, placing the transmission belt 322 within the receiving space 331 can prevent the transmission belt 322 from getting caught in the peripheral components during use, thereby improving the safety of the cutting module 300.

[0058] Optionally, the cutting mechanism 310 can be a cutting gun. The cutting gun can be fixed to the rotating base 323 using a movable pressure plate 311. The movable pressure plate 311 can be opened or closed using bolts, facilitating the installation, replacement, or maintenance of the cutting gun. The rotation drive component 321 can be a motor, etc.

[0059] In some embodiments, the profile cutting device 1000 further includes a controller electrically connected to the first movable mechanism 210, the second movable mechanism 220, and the rotating mechanism 320. The controller controls the cutting mechanism 310 to move along the contour of the profile. Using the controller's control function, the trajectory of the cutting mechanism 310 can be set, and the cutting mechanism 310 can move along the set trajectory under the combined action of the first movable mechanism 210, the second movable mechanism 220, and the rotating mechanism 320, thereby achieving the cutting of the steel 2000. It is understood that the movement trajectory of the cutting mechanism 310 is set according to the cross-sectional shape (i.e., different types of steel 2000, such as I-beams and angle steel), size, specifications, etc., of the steel 2000. The controller can be a microcontroller, a single-chip microcomputer, an MCU component, etc.

[0060] Secondly, please refer to Figure 8 This application provides a profile cutting method, including:

[0061] S100. Push the frame 410 closer to the profile to be cut;

[0062] S200. Adjust the position of the support module 100 on the frame 410 so that the support module 100 is close to the profile;

[0063] S300. Drive clamping structure 110 clamping profile;

[0064] S400. The locking mechanism locks the support module 100 and the frame 410 together;

[0065] S500. The moving module 200 drives the cutting module 300 to move on the movable plane, and the cutting mechanism 310 cuts the profile along the contour trajectory of the profile.

[0066] The above-described cutting method enables multi-level positioning for cutting steel 2000. First, pushing the frame 410 closer to the profile to be cut achieves initial positioning of the cutting device 1000 and the steel 2000, i.e., rapid coarse positioning. Second, by adjusting the position of the support module 100 on the frame, the support module 100 can drive the moving module 200 and the cutting module 300 closer to the steel 2000, achieving a second level of positioning. Third, the clamping structure 110 on the floating plate 120 extends and clamps the steel 2000, achieving mutual fixation between the cutting device 1000 and the steel 2000, thus achieving a more precise third level of positioning. Utilizing this multi-level positioning scheme to determine the relative positional relationship between the cutting device 1000 and the steel 2000 enables positioning accuracy from coarse to fine, helping to improve positioning efficiency and the cutting precision of the steel 2000.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
