According to the cross-sectional shape, there are mainly channel steel, angle steel, I-beam, round steel, flat steel and H-beam. Among them, round steel represented by rebar is the most widely used. In construction, rebar usually needs to be processed into various shapes, the most basic of which is to bend it at the required angle.

[0003] Chinese patent CN112845965A discloses a steel structure profile bending and forming processing system, which relates to the field of steel structure profile processing devices, including a support frame arranged on the ground and a driving wheel set arranged above the support frame for driving the steel bar feeding, and a clamping mechanism for clamping the steel bar and a bending mechanism for bending the steel bar are sequentially arranged on one side of the length direction of the support frame and in the direction away from the support frame.

[0005] The purpose of the present invention is to provide a steel structure profile bending device and an operating method thereof, so as to solve the problem that the bending angle of the steel bar cannot be measured in time and accurately, resulting in low bending processing quality.

[0006] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0008] When the free end of the telescopic rod is extended and drives the bending mechanism to move backward, the bending mechanism and the two guide wheels jointly bend the steel bar;

[0009] A measuring mechanism is arranged between the bottom surface of the bending mechanism and the top surface of the bottom plate, and the measuring mechanism is used to measure the angle at which the steel bar is bent.

[0010] Preferably, the bending mechanism comprises a mounting head and a bending shaft, the mounting head is fixedly mounted on the free end of the telescopic rod, the cross section of the mounting head is a U-shaped structure, and the bending shaft is vertically fixed inside the U-shaped structure.

[0011] Preferably, the sides of the two guide wheels are provided with annular grooves along the circumferential direction, and the two annular grooves jointly support the steel bars. When the mounting head moves backward, the mounting head drives the bending axis to move backward to bend the steel bars.

[0012] Preferably, the measuring mechanism includes a pressure sensor, a camera and scale lines, the scale lines are arranged on the top surface of the base plate and distributed along the length direction of the base plate, the pressure sensor is arranged between the inner wall of the mounting head and the bending axis, and the camera is installed on the bottom surface of the mounting head.

[0013] Preferably, a mounting tube is vertically fixed on the bottom surface of the mounting head, the camera is arranged inside the mounting tube, and the bottom end of the camera is higher than the bottom end of the mounting tube.

[0014] Preferably, a brush is installed on the rear end of the bottom surface of the mounting head, and the bottom end of the brush is closely distributed along the scale line.

[0015] Preferably, a mounting through hole is radially opened in the bending shaft, and a resistance plate, a spring and a resistance rod are arranged in the mounting through hole. The resistance plate is distributed closely against the pressure sensor, and the resistance rod is slidably inserted in the mounting through hole. The outer end of the resistance rod extends to the outside of the mounting through hole, and the spring is arranged between the resistance plate and the resistance rod.

[0016] Preferably, sliders are fixed on both sides of the mounting head via L-shaped rods, a strip slide groove is provided on the top surface of the base plate, the strip slide groove and the telescopic rod are parallel to each other, and the slider is slidably arranged in the strip slide groove.

[0017] Preferably, it also includes a control center, a display module and a computing module, the pressure sensor, the camera, the telescopic rod, the display module, the computing module are all electrically connected to the control center, and the display module is arranged on the top surface of the base plate.

[0018] In addition, the present invention also discloses an operating method of a steel structure profile bending device, comprising the following steps:

[0019] S1: The control center starts and extends the telescopic rod, and the free end of the telescopic rod drives the bending axis to move backward through the mounting head;

[0020] S2: When the pressure sensor detects that the pressure value is greater than zero, the camera is turned on through the control center, and the camera captures the scale value of the corresponding scale line at this time;

[0021] S3: The camera transmits the captured scale value to the control center in real time, and the control center calculates the bending angle of the steel bar in real time through the calculation module, and the display module displays the bending angle of the steel bar in real time;

[0022] S4: When the bending angle of the steel bar reaches a predetermined angle, the telescopic rod is closed through the control center.

[0023] Compared with the prior art, the steel structure profile bending device using the above technical solution has the following beneficial effects:

[0024] 1. During use, the staff first places the steel bar between the two annular grooves. The two annular grooves can stably support the steel bar to prevent the steel bar from accidentally falling, which is beneficial to the subsequent bending of the steel bar. When the free end of the telescopic rod extends backward, the free end of the telescopic rod drives the installation head to move backward, and the installation head drives the bending shaft to move backward. The backward movement of the bending shaft can bend the steel bar, and at the same time, the steel bar slides relatively in the two annular grooves to adapt to the bending of the steel bar. In addition, a recessed structure is formed between the installation head and the bending shaft, and the steel bar is limited by the recessed structure and the two annular grooves, so that the steel bar is always bent in the horizontal plane, thereby improving the bending quality of the steel bar;

[0025] 2. During use, when the bending axis moves backward and just touches the steel bar, the bending axis is squeezed by the steel bar and slightly deformed. The bending axis squeezes the pressure sensor so that the detection pressure of the pressure sensor is greater than zero. At this time, turn on the camera and shoot the corresponding scale value on the scale line, and record the corresponding scale value when the steel bar is about to bend, so as to facilitate the subsequent calculation and processing of the bending angle of the steel bar. In addition, during the process of the camera moving backward, the camera shoots the scale value on the scale line in real time and transmits the scale value to the control center. The control center calculates the bending angle of the steel bar through the calculation module and transmits the bending angle to the display module in real time. The staff can understand the bending angle of the steel bar in real time through the display module, so as to grasp the bending condition of the steel bar in real time, so that when the steel bar is bent to the required angle, the operation can be stopped in time, thereby improving the operation accuracy;

[0026] 3. During use, when the bending shaft moves backward, the bending shaft drives the resistance rod to move backward. When the outer end of the resistance rod contacts and squeezes the steel bar, the steel bar reacts to the resistance rod, so that the inner end of the resistance rod squeezes the spring, and the spring squeezes the resistance plate forward, and the resistance plate squeezes the pressure sensor forward, so that the pressure value detected by the pressure sensor is greater than zero, which means that the steel bar is just at the critical point where it is about to bend and deform. Among them, the spring has a buffering effect, which can prevent the resistance plate from rigidly squeezing the pressure sensor, and plays a role in protecting the pressure sensor, so as to smoothly measure the bending angle of the steel bar. In addition, when the steel bar is taken out after the bending is completed, the resistance rod moves and returns to its initial position under the elastic force of the spring to facilitate the next angle measurement operation;

[0027] 4. During use, when the installation head moves backward, the installation head drives the brush to move backward, and at the same time, the bottom end of the brush moves backward to clean up the steel bar debris that has fallen on the scale line, to prevent the steel bar debris from blocking the scale value on the scale line, so that the camera can accurately capture the scale value, which is conducive to the smooth measurement of the bending angle of the steel bar.

[0036] The present invention is further described below in conjunction with the accompanying drawings, wherein the terms "front", "rear", "left" and "right" in this embodiment are all Figure 3 Specifically, the position of the fixed block 21 is the front, and the position of the scale line 5 is the back.

[0037] Embodiment 1:

[0038] like Figure 1-4 A steel structure profile bending device shown in the figure includes a horizontally arranged base plate 1, wherein the base plate 1 is a rectangular plate-shaped structure, guide wheels 3 are rotatably provided at positions on both sides of the top surface of the base plate 1, and the guide wheels 3 are located at a middle and rear position of the base plate 1, and a telescopic rod 2 is provided directly above the base plate 1 through a fixed block 21, wherein the fixed block 21 is fixedly arranged at a middle position of the front end of the top surface of the base plate 1, the telescopic rod 2 is an electric telescopic rod and is distributed in the horizontal direction, and the two guide wheels 3 are symmetrically distributed about the telescopic rod 2, wherein the bottom end of the guide wheel 3 is rotatably connected between the rotating shaft and the top surface of the base plate 1, and a bending mechanism 4 is installed on the free end of the telescopic rod 2, and a steel bar 7 to be bent is inserted between the bending mechanism 4 and the two guide wheels 3.

[0039] In use, the staff first places the steel bar 7 to be bent between the two guide wheels 3, then starts and extends the telescopic rod 2. When the free end of the telescopic rod 2 extends and drives the bending mechanism 4 to move backward, the bending mechanism 4 and the two guide wheels 3 jointly clamp the steel bar 7, continue to extend the free end of the telescopic rod 2, and the bending mechanism 4 continues to move backward. Thus, under the joint action of the bending mechanism 4 and the two guide wheels 3, the bending mechanism 4 bends the steel bar 7. The steel bar 7 moves relative to the two guide wheels 3, and at the same time, the guide wheel 3 rotates around its own axis to facilitate the movement of the steel bar 7, thereby bending the steel bar 7.

[0040] like Figure 5-7 As shown, the bending mechanism 4 includes a mounting head 41 and a bending shaft 42. The mounting head 41 is fixedly mounted on the free end of the telescopic rod 2. The cross section of the mounting head 41 is a U-shaped structure, and the opening end of the U-shaped structure is distributed backward. The bending shaft 42 is vertically fixed inside the U-shaped structure. Figure 4 As shown, the sides of the two guide wheels 3 are provided with annular grooves 31 along the circumferential direction, and the two annular grooves 31 jointly support the steel bars 7 .

[0041] During use, the staff first places the steel bar 7 between the two annular grooves 31. The two annular grooves 31 can stably support the steel bar 7 to prevent the steel bar 7 from accidentally falling, which is beneficial to the subsequent bending of the steel bar 7. When the free end of the telescopic rod 2 extends backward, the free end of the telescopic rod 2 drives the installation head 41 to move backward, and the installation head 41 drives the bending shaft 42 to move backward. The backward movement of the bending shaft 42 can bend the steel bar 7. At the same time, the steel bar 7 slides relatively in the two annular grooves 31 to adapt to the bending of the steel bar 7. In addition, a concave structure is formed between the installation head 41 and the bending shaft 42, and the steel bar 7 is limited by the concave structure and the two annular grooves 31, so that the steel bar 7 is always bent in the horizontal plane, thereby improving the bending quality of the steel bar 7.

[0042] like Figure 5-7 As shown, a measuring mechanism is provided between the bottom surface of the bending mechanism 4 and the top surface of the bottom plate 1, and the measuring mechanism is used to measure the bending angle of the steel bar 7. Specifically, the measuring mechanism includes a pressure sensor 43, a camera 441 and a scale line 5, wherein the scale line 5 is provided on the top surface of the bottom plate 1 and distributed along the length direction of the bottom plate 1, wherein the scale line 5 is located directly below the extension line of the telescopic rod 2, the pressure sensor 43 is provided between the inner wall of the mounting head 41 and the bending shaft 42, the camera 441 is installed on the bottom surface of the mounting head 41, and the camera 441 is distributed vertically downward.

[0043] like Figure 8 As shown, it also includes a control center, a display module 6 and a computing module. The pressure sensor 43, the camera 441, the telescopic rod 2, the display module 6, and the computing module are all electrically connected to the control center, and the display module 6 is arranged on the top surface of the base plate 1.

[0044] In use, when the bending shaft 42 moves backward and just contacts the steel bar 7, the bending shaft 42 is squeezed by the steel bar 7 and slightly deformed. The bending shaft 42 squeezes the pressure sensor 43 so that the detection pressure of the pressure sensor 43 is greater than zero. At this time, the camera 441 is turned on and the corresponding scale value on the scale line 5 is photographed, and the corresponding scale value when the steel bar 7 is just about to bend is recorded, so as to facilitate the subsequent calculation and processing of the bending angle of the steel bar 7. In addition, in the process of the camera 441 moving backward, the camera 441 captures the scale value on the scale line 5 in real time and transmits the scale value to the control center. The control center calculates the bending angle of the steel bar 7 through the calculation module and transmits the bending angle to the display module 6 in real time. The staff can understand the bending angle of the steel bar 7 in real time through the display module 6, so as to grasp the bending condition of the steel bar 7 in real time, so that when the steel bar 7 is bent to the required angle, the operation can be stopped in time, thereby improving the operation accuracy. Specifically, if the initially recorded scale value is X0 and the scale value at a certain moment is X1, it represents that the moving distance L of the camera 441 is X1-X0, where the distance between the two guide wheels 3 is L0, and the steel bar 7 forms an isosceles right triangle between the two guide wheels 3. The bending angle of the steel bar 7 can be calculated according to the trigonometric function relationship in mathematics.

[0045] like Figure 7 As shown, a mounting through hole is radially opened in the bending shaft 42, wherein the mounting through hole is a cylindrical structure and is distributed in the horizontal direction, and a resistance plate 422, a spring 423 and a resistance rod 421 are provided in the mounting through hole, and the resistance plate 422 is distributed closely to the pressure sensor 43, and the resistance rod 421 is slidably inserted in the mounting through hole, and the outer end of the resistance rod 421 extends to the outside of the mounting through hole, and the spring 423 is arranged between the resistance plate 422 and the resistance rod 421.

[0046] In use, when the bending shaft 42 moves backward, the bending shaft 42 drives the contact rod 421 to move backward. When the outer end of the contact rod 421 contacts and squeezes the steel bar 7, the steel bar 7 reacts on the contact rod 421, so that the inner end of the contact rod 421 squeezes the spring 423, the spring 423 squeezes the contact plate 422 forward, and the contact plate 422 squeezes the pressure sensor 43 forward, so that the pressure value detected by the pressure sensor 43 is greater than zero, which means that the steel bar 7 is just at the critical point where bending deformation will occur. Among them, the spring 423 has a buffering effect, which can prevent the contact plate 422 from squeezing the pressure sensor 43 hard, and plays a role in protecting the pressure sensor 43, so that the bending angle of the steel bar 7 can be measured smoothly. In addition, when the steel bar 7 is taken out after bending, under the elastic force of the spring 423, the contact rod 421 moves and returns to the initial position to facilitate the next angle measurement operation.

[0047] like Figure 7As shown, a mounting tube 44 is vertically fixed on the bottom surface of the mounting head 41 , the camera 441 is arranged inside the mounting tube 44 , and the bottom end of the camera 441 is higher than the bottom end of the mounting tube 44 .

[0048] During use, when the steel bar 7 is bent and deformed, debris will appear on the surface of the steel bar 7 and fall to the surroundings. The design of hiding the camera 441 inside the mounting tube 44 can prevent the camera 441 from being hit by the debris, thereby protecting the camera 441, thereby extending the service life of the camera 441 and ensuring the smooth measurement of the bending angle of the steel bar 7.

[0049] like Figure 5-7 As shown, a brush 9 is installed on the rear end of the bottom surface of the mounting head 41, wherein a mounting rod is vertically fixed to the bottom surface of the mounting head 41, and the brush 9 is arranged on the bottom end of the mounting rod. The brush 9 is distributed in the horizontal direction, and the bottom end of the brush 9 is distributed closely to the scale line 5.

[0050] During use, when the installation head 41 moves backward, the installation head 41 drives the brush 9 to move backward, and at the same time, the bottom end of the brush 9 moves backward to clean up the steel bar debris that has fallen on the scale line 5, so as to prevent the steel bar debris from blocking the scale value on the scale line 5, so that the camera 441 can accurately capture the scale value, which is conducive to the smooth measurement of the bending angle of the steel bar 7.

[0051] Embodiment 2:

[0052] The difference between this embodiment and the first embodiment is that:

[0053] like Figure 1-3 As shown in Figure 5, sliders 82 are fixed on both sides of the mounting head 41 through L-shaped rods 81, a strip slide groove 83 is opened on the top surface of the base plate 1, the strip slide groove 83 and the telescopic rod 2 are parallel to each other, and the slider 82 is slidably set in the strip slide groove 83, wherein the cross-sections of the slider 82 and the strip slide groove 83 are both T-shaped structures, and the two strip slide grooves 83 are respectively located on both sides of the telescopic rod 2.

[0054] During use, when the installation head 41 moves backward, the installation head 41 drives the two sliders 82 to move backward at the same time through the two L-shaped rods 81. The two sliders 82 move in the two strip slide grooves 83 respectively, which has a guiding function and improves the stability of the installation head 41 when moving. Among them, the cross-sections of the sliders 82 and the strip slide grooves 83 are both T-shaped structures, which can prevent the sliders 82 from upwardly detaching from the strip slide grooves 83, so that the installation head 41 keeps moving in the horizontal plane, so that the steel bar 7 is always bent in the horizontal plane, thereby improving the stability of the bending of the steel bar 7 and improving the bending quality of the steel bar 7.

[0055] In addition, the present invention also discloses an operating method of a steel structure profile bending device, comprising the following steps:

[0056] S1: The control center starts and extends the telescopic rod 2, and the free end of the telescopic rod 2 drives the bending shaft 42 to move backward through the mounting head 41;

[0057] S2: When the pressure sensor 43 detects that the pressure value is greater than zero, the camera 441 is turned on through the control center, and the camera 441 captures the scale value of the scale line 5 corresponding to this time;

[0058] S3: The camera 441 transmits the captured scale value to the control center in real time, and the control center calculates the bending angle of the steel bar 7 in real time through the calculation module, and the display module displays the bending angle of the steel bar 7 in real time;

[0059] S4: When the bending angle of the steel bar 7 reaches a predetermined angle, the telescopic rod 7 is closed through the control center.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
