Description

Technical Field

[0001] This invention relates to the field of rebar cutting, and in particular to a laser rebar cutting machine for engineering construction based on steel-concrete structures. Background Technology

[0002] Rebar cutting is a crucial construction procedure in reinforced concrete structure engineering. Before cutting, the cutting length of the rebar must be accurately calculated based on the design drawings and construction specifications. Factors such as the rebar's bending adjustment value, anchorage length, and lap length must be considered to ensure that the cut rebar length meets engineering requirements. For example, for structures with seismic resistance requirements, there are strict regulations regarding the anchorage length and lap length of the rebar, and the calculation of the cutting length must be accurate. Then, rebar cutters, abrasive wheel cutters, gas cutting equipment, etc., are used to cut the rebar to the specified length.

[0003] With the development of technology, laser cutting has become increasingly popular in steel bar cutting. However, existing laser cutting equipment cannot automate the cutting of steel bars, nor can it autonomously control the cutting length. It can only perform manual cutting operations segment by segment, resulting in low efficiency and failing to meet the large-scale cutting needs of engineering construction. Therefore, a laser cutting machine for steel bars in reinforced concrete structures is proposed. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a laser cutting machine for steel reinforcement in engineering construction based on steel-concrete structures. It can automatically feed steel reinforcement, perform efficient and large-scale laser cutting, and ensure that steel reinforcement of a specified length is cut.

[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

The cutting bracket is equipped with a laser cutting component, and the conveying bracket is connected to a support frame. The support frame has two sets of guide grooves along the conveying direction. The cutting bracket is connected to a crossbeam, and flip plates are rotatably connected to both sides of the crossbeam. A support platform for horizontal support of the lower side of the flip plates is also slidably connected to the cutting bracket. A slide rail is connected to the support frame between the two sets of guide grooves. A slider is slidably connected in the slide rail, and a sliding plate is connected to the slider. An inclined block is connected to the sliding plate.

[0007] The slide rail is connected to a frame that slides against the inclined block. The inclined surface of the inclined block is also rotatably connected to a rotating plate that slides against the frame via a spring hinge. The slide plate is connected to a clamping assembly, which is used to clamp the reinforcing bars between the two sets of guide grooves. The conveying bracket is slidably connected to a top frame, which abuts against the slider. The conveying bracket is equipped with a telescopic component two, which is connected to the top frame. The conveying bracket is also equipped with a linkage assembly, which is used to drive the support platform to move downward when the top frame slides.

[0008] Preferably, the laser cutting assembly includes a longitudinal guide rail, a longitudinal guide block, a telescopic component, a transverse guide rail, a transverse guide block, and a laser cutting blade. The longitudinal guide rail is connected to the cutting bracket along the conveying direction of the reinforcing bar.

[0010] Preferably, a groove is provided on the inclined surface of the inclined block, the rotating plate is rotatably connected to the inner wall of the groove, and the plane of the rotating plate is coplanar with the inclined surface of the inclined block. A mounting frame is connected to the conveying bracket, the telescopic component is installed on the mounting frame, and collection frames are also connected to both sides of the cutting bracket.

[0011] Preferably, the clamping assembly includes a clamping frame and an arc-shaped clamping seat. The clamping frame is arranged symmetrically in two parts, one above the other, and each clamping frame is connected to the corresponding skateboard. The arc-shaped clamping seat is arranged in multiple sets on both sides of the skateboard and is installed on the skateboard by bolts.

[0012] Preferably, an arc-shaped metal retaining ring is connected to the arc-shaped clamp, and a rubber inner liner is also connected to the inner wall of the arc-shaped metal retaining ring.

[0013] Preferably, the slide rails are provided on both sides along the direction of steel bar conveying and are parallel to each other. Both ends of each slider extend on the two outer sides of the slide rail. The extended ends of the sliders on both sides are connected to mounting seats. The upper and lower sides of the mounting seats are connected to guide rods. The slide plates are slidably sleeved on the outer side of the guide rods on their respective sides. A spring is sleeved on the outer side of the guide rods between the slide plates and the mounting seats. The two ends of the clamping frame are respectively connected to the upper and lower slide plates on the same side. The upper and lower arc-shaped clamps are installed on the side of the upper and lower clamping frames that are close to each other.

[0014] Preferably, sleeves are connected to the extended ends of the sliders on both sides that are away from each other, and guide rods are also connected to the slide rails on both sides that are away from each other. The sleeves are slidably fitted on the outside of the guide rods. A spring is connected between the sleeves and the guide rods and is fitted on the outside of the guide rods. A top block is connected to the side of the sleeve away from the slide rails, and the top frame and the top block cooperate to abut against each other.

[0015] Preferably, the linkage assembly includes a top rod, a second slide block, and a rotating rod. The top rod is connected to the side of the top frame away from the slider. The second slide block is slidably connected to the conveying bracket and cooperates with the top rod to abut.

[0016] Preferably, multiple sets of guide rods are connected to both sides of the cutting bracket, and a slide seat is slidably sleeved on the outer side of each set of guide rods. The support platform is connected to the upper end of the slide seat. A spring is sleeved on the outer side of the guide rod between the slide seat and the cutting bracket. A guide rod is connected to the conveying bracket, and a slide seat is slidably sleeved on the outer side of the guide rod.

[0017] The beneficial effects of this invention are:

[0018] 1. The technical solution of this invention uses the telescopic component two to drive the top frame to contact the slider, which pushes the slider to slide towards the cutting bracket in the slide rail. During the sliding process, the inclined block connected to the sliding plate of the slider and the rotating plate connected to the inclined block will contact the frame, causing the clamping frames on the upper and lower sides to move closer to each other and clamp the steel bar through the arc-shaped clamping seat. When the inclined blocks on the upper and lower sides are compressed into the frame through contact and sliding, the inclined blocks can slide in the frame, thereby driving the steel bar clamped by the clamping frame to be delivered to the cutting bracket side. When the inclined block slips off from the end of the frame close to the cutting bracket, the sliding plate and the inclined block are bounced up and slide out of the frame again. Then the telescopic component two is retracted, and under the action of the spring three, the inclined block will be pushed to slide back to the outside of the frame. During the process, the lower end of the rotating plate will contact the frame and rotate, ensuring that the slider can be smoothly returned to the end away from the cutting bracket. By sliding back and forth, the steel bar can be continuously delivered and cut, improving the cutting efficiency.

[0019] 2. The technical solution of the present invention has a horizontally supported flip plate connected to both sides of the crossbeam. When the laser cutting component cuts the delivered steel bar, the steel bar falls onto the flip plate on both sides. As the cut steel bar accumulates, it will press the support platform down under the action of gravity, which will drive the end of the flip plate away from the crossbeam to rotate downward, so as to facilitate the unloading of the cut steel bar on it.

[0020] 3. The technical solution of the present invention can also drive the slide block two to pull the rotating rod to rotate through the telescopic component two, thereby actively pulling the support platform down, so that the end of the flip plate away from the crossbeam rotates. In this way, when the weight of the cut steel bar on the flip plate is not enough to press down the support platform, but the flip plate still needs to rotate to unload the material, it can be actively carried out by the drive of the telescopic component two.

[0033] The following will be combined with the appendix Figure 1 To be continued Figure 10 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are 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, including a cutting bracket 1 and a conveying bracket 2. The cutting bracket 1 is equipped with a laser cutting component. The conveying bracket 2 is connected to a support frame 6, and the support frame 6 has two sets of guide grooves 17 along the conveying direction. The cutting bracket 1 is connected to a crossbeam 3, and flip plates 4 are rotatably connected to both sides of the crossbeam 3. The cutting bracket 1 is also slidably connected to a support platform 15 for horizontal support of the lower side of the flip plates 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 a slide plate 22 is connected to the slider 19. An inclined block 24 is connected to the slide plate 22.

[0036] The cutting bracket 1 and the conveying bracket 2 are also fixedly connected to increase the overall stability of the equipment. At the same time, when necessary, an automated feeding module can be set on the side of the conveying bracket 2 away from the cutting bracket 1 to realize the automated feeding of the steel billet into the guide groove 17 on the conveying bracket 2.

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

[0038] A groove 25 is provided on the inclined surface of the inclined block 24. 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 frame 36 is connected to the conveying bracket 2, and the telescopic component 37 is installed on the mounting frame 36. A collection frame 5 is also connected to both sides of the cutting bracket 1, so that the rotating plate 26 can abut against the inner wall of the groove 25 under the action of the spring hinge. When an external force is applied to the rotating plate 26, if the direction of the force is towards the inclined block 24, the rotating plate 26 can stably abut against the inner wall of the groove 25 and remain parallel to the inclined surface of the inclined block 24. When the external force rotates the rotating plate 26 away from the inclined block 24, the rotating plate 26 rotates against the force of the spring hinge.

[0039] The crossbeam 3 is rotatably connected to two horizontally supported flaps 4 by support platforms 15. When the laser cutting assembly cuts the delivered steel bars, the steel bars fall onto the flaps 4 on both sides. As the cut steel bars accumulate, they will press the support platform 15 down under the action of gravity, causing the end of the flap 4 away from the crossbeam 3 to rotate downward, which facilitates the unloading of the cut steel bars on it. At the same time, the unloaded cut steel bars can 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, this invention discloses a laser cutting machine for steel bars in engineering construction based on a steel-concrete structure. Compared with Embodiment 1, 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 component 9, a transverse guide rail 10, a transverse guide block 11, and a laser cutting blade 12. The longitudinal guide rail 7 is connected to the cutting bracket 1 along the conveying direction of the steel bar. The longitudinal guide block 8 is slidably connected inside the longitudinal guide rail 7. The telescopic component 9 is installed at the lower end of the longitudinal guide block 8. The transverse guide rail 10 is installed at the output end below the telescopic component 9. The transverse guide block 11 is slidably connected inside the transverse guide rail 10. The laser cutting blade 12 is installed at the lower side of the transverse guide block 11.

[0043] The laser cutting blade 12 can slide along the direction of rebar conveying via the sliding of the longitudinal guide block 8 within the longitudinal guide rail 7, and simultaneously slide in a direction perpendicular to the direction of rebar conveying via the sliding of the transverse guide block 11 within the transverse guide rail 10. This allows the laser cutting blade 12 to be flexibly adjusted within the area of ​​the cutting bracket 1, and its height can also be adjusted via the telescopic component 9. Therefore, in specific operation, when the rebar passes through the left end of the delivery and cutting bracket 1 (the left end in the instruction manual is the...), the laser cutting blade 12 can slide along the direction of rebar conveying via the sliding of the longitudinal guide block 8 within the longitudinal guide rail 7, and simultaneously slide in a direction perpendicular to the direction of rebar conveying via the sliding of the transverse guide block 11 within the transverse guide rail 10. Figure 1 For example, on the left side (that is, the end in the direction of rebar delivery), after the rebar is aligned with the longitudinal guide block 8, the distance between it and the left end of the cutting bracket 1 can be adjusted by controlling the sliding of the longitudinal guide block 8. This distance is the length of the rebar to be cut, thus enabling the cutting of rebars of any required length according to different needs.

[0044] The lower end of the longitudinal guide rail 7 near the conveyor support 2 is connected to an alignment plate 43 that abuts against the end of the rebar. Two sets of transverse guide rails 10 are symmetrically arranged on both sides of the longitudinal guide rail 7. Each transverse guide rail 10 has a transverse guide block 11 slidably connected inside. This makes the laser cutting blade 12 symmetrically arranged on both sides of the longitudinal guide rail 7, which can achieve synchronous and efficient cutting of the rebar. There is an area between the transverse guide rails 10 on both sides that can fill the crossbeam 3, so that the rebar cut by the laser cutting blade 12 will eventually be supported on the flip plates 4 on both sides. This makes it convenient to press down on the support platform 15 by the weight of the cut rebar, and drive the end of the flip plate 4 away from the crossbeam 3 to rotate, so as to unload the cut rebar.

[0045] The alignment plate 43 is designed so that when the rebar is clamped and delivered to the top of the cutting bracket 1 by the clamping assembly, and does not contact the left end of the cutting bracket 1, the clamping can be canceled first. By controlling the sliding of the longitudinal guide block 8, the transverse guide rail 10 is moved to the left end of the rebar. Then the telescopic member 9 extends, causing the alignment plate 43 to move down and fit close to the cutting bracket 1, but without contact. At this time, the transverse guide rail 10 is controlled to move to the right, so that the alignment plate 43 moves to the right, and the left ends of the rebars that are not placed in the guide grooves 17 are contacted and aligned. Then, through reciprocating clamping and delivery, until it contacts the left end of the cutting bracket 1, and then cutting is performed to obtain a neat rebar segment of the required length.

[0046] Example 3:

[0047] like Figure 1-9 As shown, this invention discloses a laser cutting machine for steel bars in engineering construction based on a steel-concrete structure. Compared with Embodiment 2, 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 arranged symmetrically at the top and bottom, and each clamping frame 32 is connected to the corresponding slide plate 22. Multiple sets of arc-shaped clamping seats 33 are arranged on both sides of the slide plate 22 and are installed on the slide plate 22 by bolts.

[0049] The slide rails 18 are set on both sides along the direction of steel bar conveying and are parallel to each other. The two ends of each slider 19 extend on the two outer sides of the slide rail 18. The extension ends of the sliders 19 on both sides are connected to the mounting bases 20. The upper and lower sides of the mounting bases 20 are connected to the guide rods 21. The slide plates 22 are slidably sleeved on the outer side of the guide rods 21 on their respective sides. The slide plates 22 and the mounting bases 20 are connected by springs 23 sleeved on the outer side of the guide rods 21. The two ends of the clamping frame 32 are respectively connected to the slide plates 22 on the same upper and lower sides. The upper and lower arc-shaped clamps 33 are installed on the sides of the upper and lower clamping frames 32 that are close to each other. This arrangement can stabilize the sliding of the slide plates 22 on the sliders 19. When there is no external force, the slide plates 22 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 springs 23. The upper and lower clamping frames 32 and the arc-shaped clamps 33 will also be separated from each other.

[0050] Both sides of the slider 19 are connected to sleeves 28 at their respective ends, and both sides of the slide rail 18 are connected to guide rods 30 at their respective ends. The sleeves 28 are slidably fitted on the outside of the guide rods 30. A spring 31 is fitted on the outside of the guide rods 30 between the sleeves 28 and the guide rods 30. A top block 29 is connected to the side of the sleeve 28 away from the slide rail 18. The top frame 38 and the top block 29 cooperate to abut against each other, so that when the telescopic member 2 37 drives the top frame 38 to abut against the top block 29, it can drive the slider 19 to slide closer to the cutting bracket 1 and compress the spring 31. Then, when the telescopic member 2 37 retracts, the slider 19 gradually slides away from the cutting bracket 1 under the action of the spring 31 against the sleeve 28 until it returns to the initial state.

[0051] When the telescopic component 37 causes the top frame 38 to abut against the slider 19, the inclined block 24 connected to the sliding plate 22 of the slider 19 and the rotating plate 26 rotatably connected to the inclined block 24 will abut against the frame 27, causing the upper and lower clamping frames 32 to move closer together. The sliding plate 22 compresses the spring 23. At this time, the arc-shaped clamping seat 33 on the side of the upper and lower clamping frames 32 that are close to each other clamps the steel bar. When the inclined blocks 24 on the upper and lower sides are compressed into the frame 27 through the abutment and sliding, the inclined blocks 24 can slide within the frame 27, thereby causing the steel bar clamped by the clamping frame 32 to move towards the cutting direction. When the support 1 delivers the steel bars, and the inclined block 24 slides off the end of the frame 27 near the cutting support 1, the slide plate 22 and the inclined block 24 will be bounced up by the action of the second spring 23 and slide out of the outside of the frame 27 again. Then the telescopic part 37 is retracted, and the inclined block 24 will be pushed to slide and reset on the outside of the frame 27 by the action of the third spring 31. During the process, the lower end of the rotating plate 26 will contact the frame 27 and rotate, ensuring that the slider 19 can be reset smoothly to the end away from the cutting support 1. By sliding back and forth, the steel bars are continuously delivered and cut, which greatly improves the degree of automation and cutting efficiency.

[0052] The arc-shaped clamp 33 is connected to an arc-shaped metal retainer 34, and the inner wall of the arc-shaped metal retainer 34 is also connected to a rubber inner liner 35. This makes the arc-shaped clamp 33 easy to replace, so that when clamping steel bars with large diameter changes, the arc-shaped metal retainer 34 of different diameters can be replaced in time to ensure that the steel bars can be clamped firmly and delivered stably. When the diameter of the steel bars changes small, it can be adapted by the deformation of the rubber inner liner 35.

[0053] Example 4:

[0054] like Figure 1-10 As shown, this invention discloses a steel bar laser cutting machine for engineering construction based on a steel-concrete structure. Compared with Embodiment 3, this embodiment discloses the structure of the linkage component.

[0055] The linkage assembly includes a top rod 39, a slide block 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 slide block 41 is slidably connected to the conveyor bracket 2 and cooperates with the top rod 39 to abut. The rotating rod 42 is rotatably connected between the support platform 15 and the slide block 41.

[0056] When the slider 19 is in the slide rail 18 away from the cutting bracket 1, the telescopic component 37 can continue to drive the top frame 38 away from the slider 19, thereby driving the top rod 39 to abut against the slide block 41, causing the slide block 41 to pull the rotating rod 42 to rotate, thereby actively pulling the support platform 15 down, so that the end of the flip plate 4 away from the crossbeam 3 rotates. In this way, when the weight of the cut steel bar supported on the flip plate 4 is not enough to press down the support platform 15, but the flip plate 4 still needs to rotate to unload the material, it can be actively carried out by the drive of the telescopic component 37.

[0057] Multiple sets of guide rods 13 are connected to both sides of the cutting bracket 1. Each set of guide rods 13 has a sliding seat 14 slidably fitted on its outer side. The support platform 15 is connected to the upper end of the sliding seat 14. A spring 16 is fitted on the outer side of the guide rod 13 between the sliding seat 14 and the cutting bracket 1. A guide rod 40 is connected to the conveying bracket 2. A sliding seat 41 is slidably fitted on the outer side of the guide rod 40. This ensures that the support platform 15 slides stably on the cutting bracket 1. Without external force, the spring 16 will drive the support platform 15 to slide to a higher position and provide horizontal support for the flip plate 4. At the same time, the sliding seat 41 can also slide stably on the conveying bracket 2.

[0058] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention.
