Description

Technical Field

[0001] This utility model relates to the field of steel profile processing equipment, and in particular to a sawing device for processing inclined steel profiles. Background Technology

[0002] Section steel, a type of bar steel with a specific cross-sectional shape and size, such as I-beams, channel steel, and angle steel, is widely used in building structures, bridge engineering, and machinery manufacturing. In practical applications, section steel is typically cut to a fixed length to meet the requirements of structural splicing, welding, or installation. Especially in steel structure welding processes, to ensure weld strength and joint quality, it is often necessary to bevel the end faces of the section steel (i.e., beveling) or cut at non-perpendicular angles.

[0003] However, most existing steel profile sawing equipment has a relatively simple structure. Its sawing components can usually only move vertically or have only a simple horizontal rotation function. When it is necessary to cut beveled sections of steel, the tilt of the saw blade cannot be directly adjusted due to the limitations of the equipment structure. Operators can usually only change the contact angle between the steel and the saw blade by manually moving and raising one end of the steel, or by using handheld cutting equipment for manual grinding and cutting.

[0004] This traditional processing method has significant shortcomings: First, for heavy steel sections that are large and long, manually adjusting their tilt is not only extremely labor-intensive, but also prone to wobbling during cutting due to unstable support, resulting in uneven cut surfaces and severely affecting processing accuracy. Second, the lack of a precise angle adjustment mechanism makes it difficult to quantitatively control the bevel angle, leading to poor processing consistency, and frequent manual intervention also poses significant safety hazards. Therefore, there is an urgent need for a sawing device that can flexibly adjust the saw blade tilt angle, has high-precision positioning capabilities, and is easy to operate.

[0005] Therefore, this utility model proposes a sawing device for processing inclined steel sections to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a sawing device for processing inclined steel sections, which aims to improve the structural defects in the existing technology, such as cumbersome adjustment of the inclined cutting angle, low clamping and positioning efficiency, and difficulty in ensuring cutting accuracy during the steel section processing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sawing device for processing inclined steel, comprising: a workbench, and a U-shaped frame disposed below the workbench, wherein a first limiting rod is fixedly connected to the upper inner side of the U-shaped frame; and a cutting mechanism installed on the U-shaped frame, an adjusting mechanism installed inside the workbench, and a driving mechanism installed on the outer wall of the workbench.

[0008] The cutting mechanism features a structure capable of multi-dimensional posture adjustment. Specifically, the cutting mechanism includes a first motor mounted on one side of the outer wall of the U-shaped frame. The output end of the first motor passes through the U-shaped frame and is connected to a first threaded rod. A slider is threadedly connected to the outer wall of the first threaded rod.

[0009] Furthermore, the first connecting frame, the semicircular plate, and the rotating plate are combined by rotational engagement. The first motor drives the slider to move to achieve lateral positioning, the rotating plate rotates relative to the semicircular plate to achieve tilt adjustment, and the second hydraulic rod drives the saw blade to rise and fall to achieve cutting, thus forming a complete spatial multidimensional cutting system.

[0010] Preferably, a first hydraulic rod is installed on one side of the semicircular plate, and a connecting rod is connected to the output end of the first hydraulic rod. The other end of the connecting rod is fixedly connected to the outer wall of the rotating plate. An arc-shaped guide groove is formed inside the semicircular plate, and the connecting rod is slidably connected in the arc-shaped guide groove. The connecting rod is driven to slide along the groove by the extension and retraction of the first hydraulic rod, thereby precisely controlling the deflection angle of the rotating plate.

[0011] Preferably, a limiting block is fixedly connected to the outer wall of the rotating plate near the second hydraulic rod, and a second limiting rod is fixedly connected to the upper side of the hinge block. The second limiting rod is slidably connected to the inside of the limiting block.

[0012] Preferably, a rotating block is rotatably connected to one side of the hinge block, and the second connecting frame is rotatably connected to the hinge block through the rotating block; a threaded block is rotatably connected to one side of the second connecting frame, and a second threaded rod is threadedly connected inside the threaded block. By adjusting the second threaded rod, the second connecting frame is driven to rotate slightly around the rotating block to achieve high-precision compensation of the saw blade angle.

[0013] Preferably, the driving mechanism includes a third motor fixed to the outer wall of the worktable, the output end of the third motor is connected to a third threaded rod, the bottom of the U-shaped frame is threaded to the outer wall of the third threaded rod, and the U-shaped frame is slidably connected to a third limiting rod fixed to the bottom of the worktable. The third motor drives the U-shaped frame to move longitudinally along the third limiting rod to adjust the front and rear processing positions.

[0014] Preferably, the adjustment mechanism includes a support plate located above the workbench, a rotating column fixedly connected to the lower part of the support plate, the rotating column rotating through the workbench and having a gear fixedly connected to its bottom end, a third hydraulic rod installed on the lower surface of the workbench, and a rack connected to the output end of the third hydraulic rod, the rack meshing with the gear, the rack driving the gear to rotate through linear motion, thereby causing the support plate to adjust its horizontal orientation.

[0015] Preferably, an L-shaped bracket is fixedly connected to the lower surface of the workbench, and the rack is slidably connected to the inner groove of the L-shaped bracket; multiple rollers are rotatably connected to the inner bottom surface of the L-shaped bracket, and the bottom surface of the rack rolls against the upper surface of the rollers, thereby reducing frictional resistance and supporting and guiding the rack.

[0016] Preferably, the support plate has two parallel bidirectional threaded rods rotatably connected inside, and each bidirectional threaded rod has a clamping block threadedly connected to both sides of its outer wall. The support plate has a sliding groove, and the clamping block is slidably connected in the sliding groove. One end of one of the bidirectional threaded rods extends to the outside of the support plate and is fixedly connected to a belt roller.

[0017] Preferably, a belt roller is also fixedly connected to the corresponding end of the other bidirectional threaded rod, and a transmission belt is sleeved on the outer side of the two belt rollers. The transmission belt enables the two bidirectional threaded rods to rotate synchronously, thereby driving the four sets of clamping blocks to move synchronously towards the center, so as to realize the automatic centering and clamping of the steel section.

[0018] Preferably, a scale is fixedly connected to the center of the upper surface of the workbench, and the rotating column rotates through the central through hole of the scale to visually display the rotation angle of the support plate.

[0021] 2. In this utility model, by setting an adjustment mechanism, the rack is driven by a hydraulic rod to mesh with the gear at the bottom of the rotating column, and the roller in the L-shaped bracket provides rolling auxiliary support for the rack. This solves the problems of manual handling, high labor intensity and inaccurate positioning required for adjusting the horizontal cutting angle of heavy steel sections in the prior art. It achieves the technical effect of automatically driving the workpiece to rotate and change position, smooth and labor-saving transmission, and convenient and efficient angle control.

[0022] 3. In this utility model, by setting two parallel bidirectional threaded rods in the support plate and using belt rollers and transmission belts to achieve synchronous linkage of the two threaded rods, the problem of existing clamping devices being mostly unidirectional clamping, causing the steel profile to deviate from the machining center, and the low efficiency of locking one by one is solved.

[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:

[0032] Please refer to Figures 1 to 5 This utility model provides a sawing device for processing inclined steel sections, which aims to solve the structural defects in the prior art that make it cumbersome to adjust the inclined cutting angle, have low clamping and positioning efficiency, and make it difficult to guarantee cutting accuracy during the processing of steel sections.

[0033] The inclined steel section processing and sawing device includes a workbench 1 and a U-shaped frame 2 set below the workbench 1. The workbench 1 serves as the main mounting base of the entire device, supporting the steel section to be processed and the internal adjustment components. The U-shaped frame 2 supports the upper cutting components and realizes longitudinal displacement adjustment. A first limiting rod 3 is fixedly connected to the upper side inside the U-shaped frame 2. The first limiting rod 3 horizontally spans between the two inner walls of the U-shaped frame 2, providing guide support for the lateral movement of the subsequent cutting components.

[0034] To achieve longitudinal position adjustment of the U-shaped frame 2 relative to the worktable 1, the device is equipped with a drive mechanism 6 installed on the outer wall of the worktable 1. The drive mechanism 6 includes a third motor 601 fixed to the outer wall of the worktable 1 by bolts. The output end of the third motor 601 is connected to a third threaded rod 602 via a coupling. The bottom of the U-shaped frame 2 is threadedly connected to the outer wall of the third threaded rod 602. That is, the bottom of the U-shaped frame 2 is provided with a threaded hole or nut seat that matches the third threaded rod 602. The bottom of the U-shaped frame 2 is slidably connected to a third limiting rod 603 fixed to the bottom of the worktable 1. The third limiting rod 603 is set parallel to the third threaded rod 602. When the third motor 601 starts running, it drives the third threaded rod 602 to rotate. Using the thread transmission principle, the U-shaped frame 2 is driven to slide smoothly longitudinally back and forth along the third limiting rod 603, thereby adjusting the overall front and rear position of the cutting station to meet the processing requirements of steel sections of different sizes.

[0035] Based on this basic framework, the device also integrates a cutting mechanism 4 installed on the U-shaped frame 2 and an adjustment mechanism 5 installed inside the worktable 1. The cutting mechanism 4 is used to realize multi-dimensional tilting and cutting of the steel profile, and the adjustment mechanism 5 is used to realize horizontal rotation adjustment and bi-directional synchronous clamping and fixing of the steel profile to be processed. The various mechanisms cooperate with each other to form a complete automated processing system.

[0036] The cutting mechanism 4 includes a first motor 401 fixedly installed on one side of the outer wall of the U-shaped frame 2. The output shaft of the first motor 401 horizontally passes through the side wall of the U-shaped frame 2 and is connected to a first threaded rod 402 via a coupling. The first threaded rod 402 is horizontally positioned above the inside of the U-shaped frame 2. A slider 404 is threadedly connected to the outer wall of the first threaded rod 402. At the same time, the slider 404 is slidably sleeved on the outer wall of the first limiting rod 3. A first connecting frame 403 is fixedly connected to one side of the slider 404 by bolts. The first connecting frame 403 serves as the mounting carrier for the subsequent angle adjustment assembly. When the first motor 401 drives the first threaded rod 402 to rotate, the slider 404 is constrained by the threaded thrust and the guidance of the first limiting rod 3, which drives the first connecting frame 403 and the entire cutting head assembly to move horizontally, thereby precisely adjusting the lateral coordinate of the sawing position.

[0037] To adjust the tilt angle of the sawing plane, a vertically downward-facing semicircular plate 405 is welded and fixed to the outer wall of the first connecting frame 403. A rotating plate 406 with a matching shape is rotatably connected to the inner arc surface of the semicircular plate 405. A first hydraulic rod 407 is installed on one side of the outer wall of the semicircular plate 405. A connecting rod 408 is hinged to the telescopic output end of the first hydraulic rod 407. The other end of the connecting rod 408 passes through the semicircular plate 405 and is fixedly connected to the outer wall of the rotating plate 406. To limit the rotation trajectory and distribute the force, an arc-shaped guide groove concentric with the rotation center is opened inside the semicircular plate 405. The connecting rod 408 is slidably embedded in the arc-shaped guide groove. When the first hydraulic rod 407 moves to extend or retract, it pushes the connecting rod 408 to slide along the arc-shaped guide groove, forcing the rotating plate 406 to rotate circumferentially relative to the semicircular plate 405, thereby driving the subsequent saw blade assembly to change the cutting angle of the steel section and realize the bevel cutting function.

[0038] Furthermore, in order to achieve vertical feed action and ensure cutting rigidity, a vertically downward second hydraulic rod 410 is installed on one side of the rotating plate 406. The output end of the second hydraulic rod 410 is fixedly connected to a hinge block 411 through a flange. A limit block 409 is fixedly connected to the outer wall of the rotating plate 406 near the second hydraulic rod 410. A second limit rod 412 is vertically fixedly connected to the upper side of the hinge block 411. The second limit rod 412 is slidably inserted into the internal through hole of the limit block 409. This guide post cooperation structure eliminates the lateral swing of the hinge block 411 during the lifting and lowering process, ensuring smooth feed.

[0039] In the design of the end effector, a rotating block 413 is rotatably connected to one side of the hinge block 411. The second connecting frame 414 is rotatably connected to the hinge block 411 through the rotating block 413. A second motor 415 providing cutting power is installed on the side of the second connecting frame 414. A saw blade 416 is installed on the output shaft of the second motor 415. In order to achieve high-precision angle fine-tuning compensation on the basis of coarse adjustment, a second threaded rod 418 is rotatably connected inside the second connecting frame 414. A threaded block 417 is threadedly connected to the outer wall of the second threaded rod 418. The threaded block 417 is hinged to the outer wall of the rotating block 413. When the second threaded rod 418 is rotated by a knob or micro motor, the threaded block 417 is displaced. The lever principle drives the second connecting frame 414 to deflect around the rotating block 413 by a small angle, thereby correcting the final posture of the saw blade 416.

[0040] In a preferred embodiment, to achieve horizontal rotation angle adjustment of the steel section to be processed, the adjustment mechanism 5 mainly consists of a drive assembly and a rotating carrier. The adjustment mechanism 5 includes a support plate 504 horizontally suspended above the worktable 1. The support plate 504 is used to place the workpiece. A rotating column 502 is vertically welded and fixed to the bottom center of the support plate 504. The rotating column 502 passes downward through the worktable 1 and is rotatably connected to the worktable 1 through a bearing. The bottom end of the rotating column 502 extends to the bottom of the worktable 1 and is keyed to a gear 503. A horizontally arranged third hydraulic rod 511 is mounted on the lower surface of the worktable 1 through a bracket. A rack 512 is fixedly connected to the telescopic output end of the third hydraulic rod 511. The tooth surface of the rack 512 meshes with the gear 503. When the third hydraulic rod 511 drives the rack 512 to move linearly, the rotating column 502 and the support plate 504 above it are driven to rotate horizontally through the gear and rack transmission, so that the horizontal orientation of the steel section can be adjusted without moving it.

[0041] To improve the stability of the rack 512's movement and reduce frictional resistance, an L-shaped bracket 509 is fixedly connected to the lower surface of the worktable 1. The L-shaped bracket 509 is located below the rack 512, providing support and limiting. The rack 512 is slidably embedded in the inner groove formed inside the L-shaped bracket 509. Several rollers 510, evenly spaced along the length direction, are rotatably mounted on the inner bottom surface of the L-shaped bracket 509. The bottom surface of the rack 512 rolls and adheres to the upper surface of these rollers 510. This rolling friction design significantly reduces driving resistance and ensures transmission accuracy.

[0042] As another preferred embodiment, in order to achieve efficient synchronous centering and clamping of steel sections of different widths, please refer to... Figure 5 The support plate 504 has two parallel bidirectional threaded rods 505 that are horizontally rotatably connected inside it along its width direction. Each bidirectional threaded rod 505 has two clamping blocks 506 symmetrically threaded on its outer wall. The four clamping blocks 506 on the two threaded rods together form a clamping array. The upper surface of the support plate 504 has a T-shaped groove that cooperates with the bottom slider of the clamping block 506. The clamping block 506 is slidably locked in the T-shaped groove to restrict its rotation and guide its linear movement.

[0043] To achieve synchronous action on both sides under a single power source, one end of a bidirectional threaded rod 505 extends outward through the side wall of the support plate 504 and is keyed to a belt roller 507. The corresponding end of the other bidirectional threaded rod 505 on the same side is also equipped with a belt roller 507. The outer circumference of the two belt rollers 507 is tensioned with a transmission belt 508. The operator only needs to rotate one of the bidirectional threaded rods 505 with a handwheel or connected to a drive motor. The transmission belt 508 will drive the other threaded rod to rotate synchronously in the same direction, thereby driving the four sets of clamping blocks 506 to move towards the center or separate outward simultaneously, quickly completing the centering and clamping operation of the steel section.

[0044] In addition, to facilitate intuitive reading of the horizontal rotation angle value, a scale 501 is concentrically fixed at the center of the upper surface of the worktable 1, and the rotating column 502 passes through the central through hole of the scale 501. By observing the position of the edge of the support plate 504 relative to the indicated position of the scale line on the scale 501, the operator can accurately control the rotation angle.

[0045] Working principle: When it is necessary to process the steel profile, the workpiece is first clamped and positioned. The steel profile to be processed is placed on the upper surface of the support plate 504. At this time, one of the bidirectional threaded rods 505 is manually rotated. Through the transmission action of the belt roller 507 and the transmission belt 508, the other bidirectional threaded rod 505 is driven to rotate synchronously. The four sets of clamping blocks 506 on the two rods are driven by the threads to move synchronously toward the center, thereby quickly and steadily clamping the steel profile and automatically centering it to ensure the accuracy of the processing center line.

[0046] Subsequently, the horizontal angle and longitudinal position of the steel section are adjusted according to the cutting requirements. The third hydraulic rod 511 is activated, which pushes the rack 512 to slide smoothly on the roller 510 inside the L-shaped bracket 509. The rack 512 drives the gear 503 to rotate, which in turn drives the rotating column 502 and the support plate 504 above it to rotate together with the steel section. The angle is adjusted to the preset horizontal cutting angle with reference to the dial 501. At the same time, the third motor 601 is activated to drive the third threaded rod 602 to rotate, which drives the U-shaped frame 2 to move longitudinally along the third limit rod 603, and the cutting mechanism 4 is coarsely positioned at the section of the steel section to be cut.

[0047] Next, the posture of the cutting mechanism 4 is set according to the process requirements. If bevel cutting is required, the first hydraulic rod 407 is activated to extend and retract, and the rotating plate 406 is pushed to rotate within the semi-circular plate 405 through the connecting rod 408, so that the saw blade 416 is tilted to the target bevel angle. At the same time, the first motor 401 is activated to fine-tune the lateral position of the slider 404 on the first limit rod 3 to align with the cutting point. If higher precision angle correction is required, the deflection angle of the second connecting frame 414 relative to the hinge block 411 can be fine-tuned by rotating the second threaded rod 418.

[0048] Finally, the sawing action is executed. The second motor 415 is started to drive the saw blade 416 to rotate at high speed. The second hydraulic rod 410 is controlled to extend and push the hinge block 411 to drive the saw blade 416 to descend vertically and smoothly along the second limit rod 412. The clamped and positioned steel is precisely cut. After the cutting is completed, each mechanism reverses its movement to reset and the finished product is taken out.
