Description

Technical Field

[0001] This utility model relates to the field of steel bar processing, specifically to an intelligent steel bar bending and shearing device. Background Technology

[0002] In the construction of ultra-deep seepage barriers, the steel cage, as the core load-bearing structure that bears the enormous ground pressure and the self-weight of the wall, often uses high-strength steel bars with a main reinforcement of Φ20mm~Φ32mm or even larger specifications, while the steel bars commonly used in ordinary buildings are usually Φ6mm~Φ25mm, in order to meet the bearing requirements of the enormous pressure and the self-weight of the wall in ultra-deep environments.

[0003] The processing method commonly used in existing technology for processing equipment of this type of large-diameter, high-strength steel bars is to treat the fixed-length shearing and bending of the steel bars as two separate processes. This relies on traditional fixed shearing and bending equipment to operate separately. The steel bars are mainly transferred and re-clamped by crane or by manual handling between processes. This is not only labor-intensive but also extremely inefficient. The separation of processes and the high degree of manual dependence make it impossible to effectively connect the shearing and bending processes and to build continuous, efficient, and automated production.

[0004] Secondly, traditional shearing equipment lacks an effective rebar positioning and balancing mechanism. When shearing large rebars, the rebars are suspended in the air, which can easily cause quality defects such as bevels, burrs, and flattening at the cut. These defects can become fatigue crack sources for the rebars under complex loads at ultra-deep depths, threatening structural safety. Utility Model Content

[0005] To address the issues of unautomated continuous production and rebar balancing in existing technologies, this application provides an intelligent rebar bending and shearing device.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: An intelligent rebar bending and shearing device includes a hydraulic shearing mechanism and a rebar bending mechanism, and a sorting and transport trough disposed on the discharge side of the hydraulic shearing mechanism. The sorting and transport trough contains at least two sets of positioning and sorting units. Each positioning and sorting unit includes a first wedge block, a feeding roller, and a second wedge block arranged sequentially at intervals. Both the first and second wedge blocks are telescopic structures and are inclined relative to each other, forming a V-shaped angle. At least one side of the sorting and transport trough is also provided with a material preparation rack, and the other side of the material preparation rack is provided with a positioning angle groove. The positioning angle groove is inclined at an angle of 10°-40° along its length. The rebar bending mechanism is disposed at the lower end of the positioning angle groove's outlet. The device also includes a main control unit, which is electrically connected to the hydraulic shearing mechanism, the rebar bending mechanism, and the positioning and sorting units.

[0007] Furthermore, the rebar bending mechanism includes a machine body and a fixed wheel assembly and a moving wheel mounted on the machine body; the fixed wheel assembly includes two fixed wheels, and the moving wheel is located on one side of the fixed wheel assembly, situated on the perpendicular bisector of the line connecting the centers of the two fixed wheels, forming a bending channel between the moving wheel and the two fixed wheels for the rebar to pass through; the moving wheel is connected to an adjustment mechanism for driving the moving wheel closer to or further away from the fixed wheels to adjust the width of the bending channel.

[0008] Furthermore, the table surface of the material preparation rack is inclined at an angle of 10°-40° along its own width direction, and the positioning corner groove 31 is provided on the lower side of the table surface.

[0009] Furthermore, it also includes a robotic arm located on the side of the positioning corner groove for feeding the cut steel bars that have slid into the positioning corner groove into the steel bar bending mechanism.

[0010] Furthermore, the positioning corner groove is provided with a transmission roller whose rolling direction is toward the steel bar bending mechanism 4.

[0011] Furthermore, a linear drive push rod for pushing the sorted steel bars into the steel bar bending mechanism is installed in the positioning corner groove.

[0012] Furthermore, the material preparation rack is equipped with a material level detection device that is signal-connected to the main control unit and used to detect the stacking status of the sorted steel bars. The material level detection device includes a through-beam photoelectric sensor.

[0013] Furthermore, the hydraulic shearing mechanism also includes a rebar clamping mechanism. The hydraulic shearing mechanism is equipped with a first hydraulic power component for driving the shearing head to rise and fall, and a second hydraulic power component for driving the rebar clamping mechanism; the shearing head is a beveled shearing head.

[0014] Furthermore, both the feeding roller and the material preparation rack are covered with a rubber layer.

[0015] Beneficial effects: The intelligent rebar bending and shearing device provided in this application, by setting up a V-shaped positioning opening between multiple sets of feeding rollers with a first wedge block and a second wedge block that can be raised and lowered and have opposite inclined surfaces, automatically constrains and centers the rebar before shearing, effectively overcoming the problems of slanted cuts and burrs caused by the rebar being suspended or unstable in positioning in traditional shearing. Furthermore, by utilizing the independent telescopic control of the wedge blocks in conjunction with the inclined material rack and positioning corner groove, the device realizes the automatic sorting and directional sliding conveying of the sheared rebar, seamlessly connecting the shearing, transfer and bending processes, and constructing a complete automated production line. This significantly reduces manual handling and secondary clamping while ensuring the precision of rebar processing, thus greatly improving production efficiency. In addition, by setting up a material level detection device linked with the main control unit, the stacking status of the prepared materials can be monitored in real time and the sorting path can be intelligently scheduled. The independent rebar clamping mechanism and the coordinated control of the inclined blade shearing head further ensure the static state of the rebar at the moment of shearing, further improving the cutting quality and operational safety. This constitutes a complete intelligent rebar processing solution, effectively solving the technical problems of difficult quality control and production process disruption in the construction of ultra-deep anti-seepage walls for large-diameter rebar.

[0022] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this application does not imply that the component is required to be absolutely horizontal or suspended, but rather that it may be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it may be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] like Figure 1 , Figure 2 As shown in the figure, this utility model discloses a specific structure of an intelligent rebar bending and shearing device, including a hydraulic shearing mechanism 1 and a rebar bending mechanism 4. It also includes a sorting and transport trough 2 located on the discharge side of the hydraulic shearing mechanism 1. The sorting and transport trough 2 contains at least two sets of positioning and sorting units. Each positioning and sorting unit includes a first wedge block 22, a feeding roller 21, and a second wedge block 23 arranged sequentially at intervals. Both the first wedge block 22 and the second wedge block 23 are telescopic structures and are inclined relative to each other, forming a V-shaped angle. At least one side of the sorting and transport trough 2 is also provided with a material preparation rack 3, and the other side of the material preparation rack 3 is provided with a positioning angle groove 31. The positioning angle groove 31 is inclined at an angle of 10°-40° along its length. The rebar bending mechanism 4 is located at the lower end of the positioning angle groove 31. The device also includes a main control unit, which is electrically connected to the hydraulic shearing mechanism 1, the rebar bending mechanism 4, and the positioning and sorting units.

[0025] The working principle of this utility model will be further explained below by combining its states when it is not in operation and when it is in operation.

[0026] When this utility model is not in operation, both the first wedge block 22 and the second wedge block 23 are retracted into the sorting and transport trough 2. At this time, the highest point of the first wedge block 22 and the second wedge block 23 is not higher than the feeding roller 21.

[0027] When in operation, the steel bars to be processed are fed into the sorting and transport trough 2. During this process, the feeding roller 21 is simultaneously controlled by the main control unit to rotate and provide forward power. When the length of the steel bar to be processed is fully entered into the sorting and transport trough 2, the main control unit controls the first wedge block 22 and the second wedge block 23 to rise, so that the steel bar to be processed rolls into the V-shaped angle. At this time, the lowest point of the inclined surface of the first wedge block 22 and the second wedge block 23 is higher than the sorting and transport trough 2.

[0028] The reason for pre-balancing the reinforcing bars is to avoid burrs on the end face of the reinforcing bars after they are cut. After balancing, the hydraulic shearing mechanism 1 presses down and the reinforcing bars to be processed are cut off. Then, the first wedge block 22 or the second wedge block 23 retracts and the cut reinforcing bars roll down the inclined surface of the wedge block into the material rack 3 located on one side of the sorting and transport trough 2, and enter the positioning corner groove 31. Since the positioning corner groove 31 has a certain inclination angle along the length direction, the reinforcing bars will slide into the bending mechanism 4 and be bent by the bending mechanism 4.

[0029] After completing this processing, the main control unit controls the first wedge block 22 or the second wedge block 23 to retract into the sorting and transport trough 2, and the cutter head of the hydraulic shearing mechanism 1 is raised and reset to prepare for the next processing.

[0030] It is understandable that in practical applications, material racks 3 can also be set on both sides of the sorting and transport trough 2 to sort steel bars of different lengths. Since the first wedge block 22 and the second wedge block 23 both have inclined surfaces, after the steel bars are cut, the main control unit can selectively control the first wedge block 22 or the second wedge block 23 to retract individually according to the preset program.

[0031] If the steel bars need to be sorted to the right-side storage rack, keep the first wedge block 22 raised and only retract the second wedge block 23. The steel bars will roll into the right-side area along the inclined surface of the first wedge block 22. Conversely, if the steel bars need to be sorted to the left-side storage rack, retract the first wedge block 22 and the steel bars will slide into the left-side storage rack along the inclined surface of the second wedge block 23.

[0032] Technical effects: This invention solves the problem of end-face burrs caused by the suspension of steel bars in traditional shearing by automatically centering and stabilizing the steel bars through a liftable V-shaped angle composed of retractable wedge blocks. Then, by utilizing the telescopic movement of the wedge blocks and the inclined channel design, it realizes automatic sorting and gravity-flow conveying of the sheared steel bars, seamlessly connecting the shearing, transfer and bending processes to form a highly automated and continuous processing flow. This improves production efficiency and reduces equipment complexity and manual labor intensity while ensuring processing accuracy.

[0033] Example 2: To achieve better technical results, this embodiment makes further improvements based on the first embodiment. The difference between this embodiment and the first embodiment is that an auxiliary device for feeding in the cut steel bars and a detection device for detecting the state of the stacked steel bars are added, and specific limitations are made on the steel bar bending mechanism 4.

[0034] Specifically, in this embodiment, combined with Figure 3 and Figure 4As shown, the rebar bending mechanism 4 mainly includes a machine body, a fixed wheel assembly mounted on the machine body, and a moving wheel 43. The fixed wheel assembly consists of a first fixed wheel 41 and a second fixed wheel 42 arranged side by side with a certain gap; the moving wheel 43 has a certain gap with the fixed wheel assembly, which forms a rebar bending channel for the rebar to pass through. To adapt to the processing needs of rebars of different specifications, an adjusting mechanism 44 is connected below the moving wheel 43. In this embodiment, the adjusting mechanism 44 is preferably a lockable screw structure. By rotating the screw, the moving wheel 43 is driven to move closer to or away from the fixed wheel assembly, thereby precisely adjusting the width of the bending channel. Behind the bending channel, an adjustable auxiliary pin 45 is provided to suppress the stress rebound of the rebar during bending and ensure the stability of the formed curvature. After the bending operation is completed, the formed rebar is sent to the discharge platform 5 at the rear.

[0035] It is understandable that both the fixed wheel assembly and the moving wheel 43 can rotate, and the driving method can adopt conventional technical means such as motors. During operation, the sheared steel bars slide from the preparation table 3 into the inclined positioning angle groove 31 and are automatically guided into the bending channel; by adjusting the channel gap and driving the wheel assembly to rotate, the straight steel bars can be bent to the preset curvature. The smaller the width of the steel bar bending channel, the greater the final curvature.

[0036] In addition, the first fixed wheel 41, the second fixed wheel 42 and the moving wheel 43 are all provided with anti-slip structures on the wheel surfaces that come into contact with the reinforcing bars to increase the friction with the surface of the reinforcing bars.

[0037] The platform of the material preparation rack 3 is inclined at a certain angle along its width direction. The preferred range of the inclination angle is between 10° and 40°. The positioning corner groove 31 is set on the lowest side of the inclined platform. By using gravity, the steel bars that fall into the material preparation rack 3 after being sheared will automatically roll to the lower side and finally gather and be oriented into the positioning corner groove 31.

[0038] The specific value of the tilt angle of the material preparation table 3 will have different technical effects depending on different application scenarios and requirements: When the inclination angle is set to a small angle of 10°-20°, the downward force of the steel bar is relatively gentle, which can effectively avoid the violent collision, bouncing or surface damage caused by the heavy steel bar rolling down at too high speed.

[0039] When the inclination angle is set at a moderate angle of 20°-30°, the optimal balance between conveying efficiency and stability can be achieved. At this angle, the reinforcing bars can roll normally into the positioning groove 31 by their own weight, avoiding jamming that may occur due to an excessively small angle. At the same time, their motion inertia is easy to control, making it applicable to most engineering projects.

[0040] When the inclination angle increases to a larger angle of 30°-40°, the steel bars will obtain the maximum gravitational acceleration, enabling rapid conveying, improving the emptying efficiency of the material preparation rack and the response speed to high-frequency shearing operations. This design is particularly suitable for construction scenarios with high-intensity production. Correspondingly, a rubber layer is also provided on the material preparation rack 3 to reduce the vibration of the steel bars at large angles.

[0041] This tilt angle design enables the material preparation rack 3 to meet the specific requirements for smoothness, efficiency and durability of conveying under different working conditions while ensuring the automatic collection function of steel bars.

[0042] To improve the automation level of steel bar processing for ultra-deep seepage-proof walls, this utility model adopted an inclined material preparation rack 3 and a positioning corner groove 31 from the initial design stage. However, during the implementation of on-site construction, the inventors found that there were still uncertainties in the steel bar transportation process. To eliminate such hidden dangers and ensure smooth production flow, this utility model further made redundant designs by introducing a sensor-based real-time monitoring link and an independent auxiliary propulsion device to form an intelligent anti-jamming closed-loop control, ensuring the high reliability of the device.

[0043] Specifically, in the first preferred embodiment, the auxiliary propulsion device is set as a robotic arm 6. The end effector of the robotic arm 6 can be a gripper. When the robotic arm 6 detects that the rebar is stuck in the positioning corner groove 31, it performs a gripping action. The robotic arm 6 picks up the rebar from the positioning corner groove 31 and moves it to the processing station of the rebar bending mechanism 4 in an arc trajectory. By actively gripping, the risk of the rebar getting stuck in the slide due to friction and collision is avoided.

[0044] It is understood that the robotic arm 6 described in this embodiment of the present invention can be a multi-degree-of-freedom industrial robotic arm commonly used in this technical field. The structure, drive, and autonomous control principles of such robotic arms are well known to those skilled in the art and belong to mature existing technology. The inventive point of this invention is not to improve any structure or basic function of the robotic arm 6 itself, but to innovatively integrate it as an automated execution terminal into a continuous production system of shearing, sorting, and bending. Its main contribution is the specific functions of grasping, transferring, and placing in the overall control logic, thereby cooperating with other components of the system to form an unmanned and intelligent steel bar processing production line.

[0045] In the second preferred embodiment, the auxiliary propulsion device is configured as a plurality of transmission rollers installed in the positioning corner groove 31 along the inclined direction of the positioning corner groove 31. When the reinforcing bar slides into the positioning corner groove 31 and presses on the rollers, the continuously rotating rollers provide a stable axial thrust for the reinforcing bar, helping it to overcome frictional resistance and ensuring that the reinforcing bar can slide smoothly and reliably to the bending position.

[0046] In the third preferred embodiment, the auxiliary propulsion device is configured as a linear drive push rod, which can be a hydraulic cylinder or an electric screw module. When the reinforcing bar is detected to have slid into the positioning groove 31, the push rod pushes the reinforcing bar and sends it into the reinforcing bar bending mechanism 4 through linear motion.

[0047] The linear drive push rod described is the same as that of the robotic arm 6, and is also a commonly used product in this field, so it will not be described in detail here.

[0048] In this embodiment, the detection device is set as a through-beam photoelectric sensor. Under normal operation of this device, there are generally no steel bars left on the preparation platform 3, because this device usually adopts an intelligent production line setting that integrates shearing and bending. If the detection device detects steel bars left on the preparation platform 3, it means that the operation has stalled. This status signal is fed back to the main control unit as the highest priority basis for the sorting path decision of the sorting transport trough 2. Once a stall is determined, the main control unit will immediately command the sorting transport trough 2 to stop sorting to that side, thereby realizing the closed-loop linkage between sorting execution and downstream station status, ensuring the smooth operation of the entire production line.

[0049] Furthermore, the hydraulic shearing mechanism 1 includes two independent hydraulic drive systems. The first hydraulic power component 12 serves as the main shearing power source, directly driving the oblique shearing head 11 to move vertically up and down to complete the shearing action. Simultaneously, a second hydraulic power component 13 is specifically designed to drive an independent rebar clamping mechanism, which can take the form of hydraulic clamps or pressure blocks. In the actual shearing process, the main control unit issues commands according to a strict timing sequence: first, it commands the second hydraulic power component 13 to operate, driving the clamping mechanism to lock the rebar, which has been initially positioned at a V-angle; then, it activates the first hydraulic power component 12, driving the oblique shearing head 11 downwards to complete the shearing, ensuring that the rebar remains stationary at the moment it is subjected to enormous shearing force.

[0050] Even with the existing V-shaped angle providing initial radial positioning, a dedicated independent rebar clamping mechanism is still installed to further ensure the end processing quality of the ultra-deep seepage-proof wall rebar cage. The specially designed oblique shearing head generates a significant axial force during operation, causing the rebar to move along its axis. While the V-shaped angle effectively prevents rebar rolling, it is insufficient to resist this axial movement. Without rigid clamping, the rebar will experience a slight axial displacement during shearing, which, although insufficient to affect quality, should be avoided as much as possible. The combined effect of these two mechanisms creates a stable process environment for the shearing action, thereby obtaining high-quality rebar end faces.

[0051] The workflow of this utility model is as follows: Figures 1-6As shown, when the device is not in operation, both the first wedge block 22 and the second wedge block 23 are retracted into the sorting and transport trough 2, not higher than the feeding roller 21. When processing begins, the steel bar to be processed is fed into the sorting and transport trough 2, and the feeding roller 21 rotates under the control of the main control unit to provide feeding power. After the steel bar reaches the predetermined length, the main control unit controls the first wedge block 22 and the second wedge block 23 to rise, so that the steel bar rolls into the V-shaped angle formed by the inclined surfaces of the two wedge blocks for automatic centering and balancing, so as to avoid burrs on the end face during shearing. After balancing, the steel bar clamping mechanism in the hydraulic shearing mechanism 1 first acts to rigidly lock the steel bar to be sheared, and then the inclined shearing head presses down to complete the shearing. After shearing, the main control unit selectively retracts according to the preset program. The first wedge block 22 or the second wedge block 23 is returned, causing the cut steel bars to roll down the inclined surface into the material rack 3 on one side. The inclined platform of the material rack 3 allows the steel bars to automatically gather into the positioning corner groove 31 by gravity and slide towards the steel bar bending mechanism 4. During this process, if the material level detection device 32 detects that there are steel bars stuck in the material rack 3, the main control unit will pause the sorting to that side. The auxiliary propulsion device, such as the robotic arm 6, grabs and transfers the steel bars, the transmission roller assists in pushing, or the linear push rod pushes to ensure that the steel bars smoothly enter the steel bar bending mechanism 4. After the steel bar bending mechanism 4 bends the steel bars, the processed steel bars are placed into the discharge table 5. The main control unit controls the first or second wedge block to retract and the hydraulic cutter head to reset, preparing for the next processing cycle.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
