Description

Technical Field

[0001] The present invention relates to the field of steel bar cutting, in particular to a steel bar laser cutting machine for engineering construction based on steel-concrete structures. Background Art

[0002] Rebar cutting is a critical construction process in steel-concrete structural engineering. Before cutting, the desired length must be accurately calculated based on the design drawings and construction specifications. Factors such as the bar's bending adjustment, anchorage length, and overlap length must be considered to ensure the cut length meets project requirements. For example, for structures requiring earthquake resistance, strict regulations exist for anchorage and overlap lengths, necessitating accurate calculation of the cut length. The rebar is then cut to the specified length using a rebar cutter, abrasive cutter, or gas cutting equipment.

[0003] With the advancement of technology, laser cutting is becoming increasingly popular for rebar cutting. However, existing laser cutting equipment cannot automatically cut rebar or independently control the cutting length.

[0033] The following will be combined with the Figure 1 To the attached Figure 10 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0034] Example 1:

[0035] like Figure 1-8 As shown, the present invention discloses a steel bar laser cutting machine for engineering construction based on steel-concrete structure, comprising a cutting bracket 1 and a conveying bracket 2. The cutting bracket 1 is provided with a laser cutting assembly, the conveying bracket 2 is connected to a support frame 6, and the support frame 6 is provided with two sets of guide grooves 17 along the conveying direction, the cutting bracket 1 is connected to a crossbeam 3, both sides of the crossbeam 3 are rotatably connected to a flap 4, the cutting bracket 1 is further slidably connected to a support platform 15 for horizontally supporting the lower side of the flap 4, the support frame 6 between the two sets of guide grooves 17 is connected to a slide rail 18, a slider 19 is slidably connected in the slide rail 18, and the slider 19 is connected to a slide plate 22, and the slide plate 22 is connected to an inclined block 24;

[0036] The cutting bracket 1 and the conveying bracket 2 are also fixedly connected to increase the stability of the entire device. If necessary, an automated loading module can be provided on the side of the conveying bracket 2 away from the cutting bracket 1 to automatically load the steel bar blank into the guide groove 17 on the conveying bracket 2.

[0037] The slide rail 18 is connected to a frame 27 that slides in contact with the inclined block 24. The inclined surface of the inclined block 24 is also rotatably connected to a turn plate 26 that slides in contact with the frame 27 through a spring hinge. The slide plate 22 is connected to a clamping assembly, which is used to clamp the steel bars between the two sets of guide grooves 17. The conveying bracket 2 is slidably connected to a top frame 38, and the top frame 38 is in contact with the slider 19. A telescopic part 2 37 is installed on the conveying bracket 2, and the telescopic part 2 37 is connected to the top frame 38. A linkage assembly is also provided on the conveying bracket 2, which is used to drive the support platform 15 to move downward when the top frame 38 slides.

[0038] A groove 25 is provided on the inclined surface of the inclined block 24, and the rotating plate 26 is rotatably connected to the inner wall of the groove 25, and the plane of the rotating plate 26 is coplanar with the inclined surface of the inclined block 24. A mounting bracket 36 is connected to the conveying bracket 2, and the telescopic part 2 37 is installed on the mounting bracket 36. The collecting frames 5 are also connected to both sides of the cutting bracket 1, so that the rotating plate 26 can contact the inner wall of the groove 25 under the action of the spring hinge. Then, when an external force acts on the rotating plate 26, when its action direction is toward the side of the inclined block 24, the rotating plate 26 can stably contact the inner wall of the groove 25 and maintain parallelism with the inclined surface of the inclined block 24. When the external force on the rotation of the rotating plate 26 is away from the side of the inclined block 24, the rotating plate 26 overcomes the force of the spring hinge and rotates.

[0039] The two sides of the beam 3 are rotatably connected with horizontal flaps 4 supported by the support platform 15, so that when the laser cutting assembly cuts the delivered steel bars, the steel bars fall onto the flaps 4 on both sides, and as the cut steel bars gather, the support platform 15 will be pressed downward under the action of gravity, driving the flap 4 to rotate downward away from one end of the beam 3, making it convenient to unload the cut steel bars supported on it. At the same time, the cut steel bars after unloading can also be collected in the collection frames 5 on both sides of the cutting bracket 1.

[0040] Example 2:

[0041] like Figure 1-8 As shown, the present invention discloses a steel bar laser cutting machine for engineering construction based on steel-concrete structure. Compared with the first embodiment, this embodiment discloses the structure of the laser cutting component.

[0042] The laser cutting assembly includes a longitudinal guide rail 7, a longitudinal guide block 8, a telescopic piece 9, a transverse guide rail 10, a transverse guide block 11, and a laser cutting knife 12. The longitudinal guide rail 7 is connected to the cutting bracket 1 along the transmission direction of the steel bar, the longitudinal guide block 8 is slidably connected in the longitudinal guide rail 7, the telescopic piece 9 is installed at the lower end of the longitudinal guide block 8, the transverse guide rail 10 is installed at the output end on the lower side of the telescopic piece 9, the transverse guide block 11 is slidably connected in the transverse guide rail 10, and the laser cutting knife 12 is installed on the lower side of the transverse guide block 11.

[0043] The laser cutting knife 12 can slide along the direction of steel bar transmission by the sliding of the longitudinal guide block 8 in the longitudinal guide rail 7, and at the same time slide in the direction perpendicular to the direction of steel bar transmission by the sliding of the transverse guide block 11 in the transverse guide rail 10, so that the laser cutting knife 12 can be flexibly adjusted in the area of ​​the cutting bracket 1, and the height can also be adjusted by the telescopic member 9. In the specific operation, when the steel bar passes through the left end of the delivery and cutting bracket 1 (the left end in the specification is the left end), the laser cutting knife 12 can be adjusted flexibly in the area of ​​the cutting bracket 1. Figure 1 For example, after the left side (that is, one end in the direction of steel bar delivery) is aligned with each other, the distance between the longitudinal guide block 8 and the left end of the cutting bracket 1 can be adjusted by controlling the sliding of the longitudinal guide block 8, which is the length of the cut steel bar, so that steel bars of any required length can be cut according to different needs.

[0044] The lower end of the longitudinal guide rail 7 close to the conveying bracket 2 is connected to an alignment plate 43 that cooperates with the end of the steel bar. Two groups of transverse guide rails 10 are symmetrically arranged on both sides of the longitudinal guide rail 7. Each transverse guide rail 10 is slidably connected to a transverse guide block 11, so that the laser cutting knife 12 is symmetrically arranged on both sides of the longitudinal guide rail 7, which can realize synchronous and efficient cutting of the steel bars. There is an area between the transverse guide rails 10 on both sides that can fill the crossbeam 3, so that the steel bars cut by the laser cutting knife 12 will eventually be carried on the flaps 4 on both sides, so as to facilitate the downward pressure of the support platform 15 by the weight of the cut steel bars, and drive the flap 4 to rotate away from the end of the crossbeam 3 to discharge the cut steel bars.

[0045] The setting of the alignment plate 43 allows, when the steel bar is clamped and delivered to the top of the cutting bracket 1 by the clamping assembly and does not conflict with the left end of the cutting bracket 1, the clamping can be canceled first, and by controlling the sliding of the longitudinal guide block 8, the transverse guide rail 10 is driven to the left end of the steel bar, and then the telescopic member 9 is extended, driving the alignment plate 43 to move down and fit close to the cutting bracket 1, but without conflict. At this time, the transverse guide rail 10 is controlled to move right, so that the alignment plate 43 moves right, so that the left ends of the unevenly placed steel bars in each guide groove 17 can be conflicted and aligned, and then they are delivered through reciprocating clamping until they conflict with the left end of the cutting bracket 1, and then cutting is performed to obtain a neat steel bar segment of the required length.

[0046] Example 3:

[0047] like Figure 1-9 As shown, the present invention discloses a steel bar laser cutting machine for engineering construction based on steel-concrete structure. Compared with the second embodiment, this embodiment discloses the structure of the clamping component.

[0048] The clamping assembly includes a clamping frame 32 and an arc-shaped clamping seat 33. The clamping frame 32 is symmetrically arranged in two upper and lower parts. Each clamping frame 32 is connected to the corresponding slide 22. There are multiple groups of arc-shaped clamping seats 33 on both sides of the slide 22 and are installed on the slide 22 by bolts.

[0049] The slide rails 18 are arranged on both sides along the steel bar transmission direction and are parallel to each other. The two ends of each slider 19 extend on both outer sides of the slide rail 18. The sliders 19 on both sides are close to each other and are connected to the mounting seat 20 on one side of the extension end. The upper and lower sides of the mounting seat 20 are connected to the guide rod 21. The slide plate 22 is slidably sleeved on the outer side of the guide rod 21 on each side. A spring 23 sleeved on the outer side of the guide rod 21 is connected between the slide plate 22 and the mounting seat 20. The two ends of the clamping frame 32 are respectively connected to the slide plate 22 on the same side of the upper and lower sides, and the upper and lower arc clamping seats 33 are installed on the side where the upper and lower clamping frames 32 are close to each other. Such an arrangement can stabilize the sliding of the slide plate 22 on the slide plate 19, and when there is no external force, the slide plates 22 sliding on the upper and lower sides of each slider 19 will be in a state of moving away from each other under the action of the spring 23, and the upper and lower clamping frames 32 and the arc clamping seats 33 are also separated from each other.

[0050] The extending ends of the sliders 19 on both sides that are away from each other are connected with sleeves 28, and the sliding rails 18 on both sides that are away from each other are also connected with guide rod three 30. The sleeve 28 is slidably sleeved on the outside of the guide rod three 30, and a spring three 31 sleeved on the outside of the guide rod three 30 is connected between the sleeve 28 and the guide rod three 30. The side of the sleeve 28 away from the slide rail 18 is connected with a top block 29, and the top frame 38 cooperates with the top block 29 to interfere with each other, so that when the telescopic part 2 37 drives the top frame 38 to interfere with the top block 29, it can drive the slider 19 to slide toward the side close to the cutting bracket 1 and compress the spring three 31. Then, when the telescopic part 2 37 contracts, the slider 19 gradually slides away from the cutting bracket 1 under the interference of the spring three 31 on the sleeve 28 until it returns to its initial state.

[0051] When the telescopic member 237 drives the top frame 38 to contact the slider 19, the inclined block 24 connected to the slide 22 of the slider 19 sliding up and down and the rotating plate 26 connected to the inclined block 24 will contact the frame 27, driving the clamping frames 32 on the upper and lower sides to approach each other, and compressing the spring 23 through the slide 22. At this time, the arc-shaped clamping seat 33 on the side where the upper and lower clamping frames 32 are close to each other clamps the steel bars. When the inclined blocks 24 on the upper and lower sides are compressed into the frame 27 through the conflicting sliding, the inclined blocks 24 can slide in the frame 27, thereby driving the steel bars clamped by the clamping frames 32 to the cutting edge. The bracket 1 is delivered from one side. When the inclined block 24 slips off the end of the frame 27 close to the cutting bracket 1, the slide plate 22 and the inclined block 24 will be bounced up by the action of the spring 23 and slide out of the outside of the frame 27 again. Then the telescopic part 2 37 will be retracted, and the inclined block 24 will be pushed to slide and reset on the outside of the frame 27 under the action of the spring 31. During the process, the lower end of the rotating plate 26 will contact with the frame 27 and rotate, ensuring that the slider 19 can be smoothly reset to the end away from the cutting bracket 1, and the reciprocating sliding can realize the continuous delivery and cutting of the steel bars, which greatly improves the degree of automation and cutting efficiency.

[0052] An arc-shaped metal clamping ring 34 is connected to the arc-shaped clamping seat 33, and the inner wall of the arc-shaped metal clamping ring 34 is also connected to a rubber inner liner 35, so that the arc-shaped clamping seat 33 is easy to disassemble and replace, so that when clamping steel bars with large diameter changes, the arc-shaped metal clamping ring 34 of different diameters can be replaced in time to ensure that the steel bars can be firmly clamped for stable delivery. When the diameter of the steel bars changes slightly, it can adapt to the changes through the deformation of the rubber inner liner 35.

[0053] Example 4:

[0054] like Figure 1-10 As shown, the present invention discloses a steel bar laser cutting machine for engineering construction based on steel-concrete structure. Compared with the third embodiment, this embodiment discloses the structure of the linkage component.

[0055] The linkage assembly includes a top rod 39, a second slide 41, and a rotating rod 42. The top rod 39 is connected to the side of the top frame 38 away from the slider 19. The second slide 41 is slidably connected to the conveying bracket 2 and cooperates with the top rod 39. The rotating rod 42 is rotatably connected between the support platform 15 and the second slide 41.

[0056] When the slider 19 is in the slide rail 18 and away from the end of the cutting bracket 1, the telescopic part 2 37 can continue to drive the top frame 38 to slide away from the slider 19, thereby driving the top rod 39 to resist the slide 2 41, driving the slide 2 41 to pull the rotating rod 42 to rotate, and then actively pull the support platform 15 downward, so that the flap 4 rotates away from one end of the beam 3. In this way, when the weight of the cut steel bars supported by the flap 4 is not enough to press down the support platform 15, but the flap 4 still needs to rotate to unload it, it can be actively carried out by the drive of the telescopic part 2 37.

[0057] There are multiple groups of guide rods 13 connected to both sides of the cutting bracket 1, and a slide 14 is slidably sleeved on the outer side of each group of guide rods 13. The support platform 15 is connected to the upper end of the slide 14, and a spring 16 is connected between the slide 14 and the cutting bracket 1 and is sleeved on the outer side of the guide rod 13. A guide rod 4 40 is connected to the conveying bracket 2, and a slide 2 41 is slidably sleeved on the outer side of the guide rod 4 40. This can ensure that the support platform 15 slides stably on the cutting bracket 1, and in the absence of external force, the spring 16 will drive the support platform 15 to slide to a high place and horizontally support the flap 4. At the same time, the slide 2 41 can also slide stably on the conveying bracket 2.

[0058] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention.
