DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.
[0024] Such as Figure 1As shown in the figure, a bending device for building hardware that is convenient to adjust includes a gantry 2. A bending assembly 1 is arranged on the upper side of the gantry 2. The lower end of the gantry 2 is fixedly connected with a fixed frame 4. On the upper left and right sides of the upper end of the fixed frame 4, fixing assemblies 3 are symmetrically arranged.
[0025] In a specific implementation, in the initial state, the bending assembly 1 is in an upper position and cannot perform the bending operation on the steel bar. Place the steel bar to be bent horizontally on the structures of the two fixing assemblies 3 that clamp the steel bar. According to the different models of the steel bars, adjust the two fixing assemblies 3 to fix the two sides of the steel bar tightly respectively, and then start the bending assembly 1 to continuously move downward to perform the bending operation on the steel bar.
[0026] Specifically, in order to enable construction workers to adjust the fixation of the steel bar according to the different models of the steel bar while completing the bending operation on the steel bar, thus providing convenience for the steel bar bending operation. Referring to the figure, the bending assembly 1 includes a motor 11 and a second rotating rod 14. The motor 11 is fixedly connected to the right side of the upper horizontal part of the gantry 2. The second rotating rod 14 is rotatably connected to the left side of the upper horizontal part of the gantry 2. The lower end of the second rotating rod 14 penetrates through the upper horizontal part of the gantry 2 and extends to the lower side of the gantry 2. The output end of the motor 11 is fixedly connected with a first rotating rod 13 through a coupling. The lower end of the first rotating rod 13 penetrates through the upper horizontal part of the gantry 2 and extends to the lower side of the gantry 2. A pulley 12 is fixedly connected to the upper sides of the outer surfaces of the first rotating rod 13 and the second rotating rod 14. Threaded rods 15 are fixedly connected to the lower ends of the first rotating rod 13 and the second rotating rod 14. Slide plates 16 are threadedly connected to the outer surfaces of the two threaded rods 15. Limiting assemblies 17 are arranged on the left and right sides of each slide plate 16. The middle part of the lower end of the slide plate 16 is fixedly connected with a bending body 18;
[0027] Further referring to Figure 3 , both of the two limiting assemblies 17 include a first slider 171. The two first sliders 171 are respectively fixedly connected to the left and right ends of the slide plate 16. Middle parts of the opposite ends of the vertical part of the gantry 2 are respectively provided with chutes 172. The first slider 171 and the chute 172 on the same side are slidably connected;
[0028] Further referring to Figure 4 , both of the two fixing assemblies 3 include rectangular plates 31. The two rectangular plates 31 are both fixedly connected to the upper end of the fixed frame 4. Electric cylinders 32 are fixedly connected to the mutually remote ends of the two rectangular plates 31. Sliding assemblies 33 are arranged on the upper sides of the two electric cylinders 32;
[0029] Further referring to Figure 5, both of the two sliding components 33 include a first slide rail 331, a second slider 332, and two second round blocks 335. The two first slide rails 331 are respectively fixedly connected to the middle of the mutually remote ends of the rectangular plate 31. The second sliders 332 on the same side are slidably connected to the first slide rail 331. On the front and rear sides of the mutually remote ends of the two second sliders 332, first round blocks 333 are fixedly connected. On the outer surfaces of the two first round blocks 333 on the same side, connecting rods 334 are rotatably connected. On the outer surfaces of the two connecting rods 334 and the two second round blocks 335 on the same side, they are respectively rotatably connected. On the upper sides of the two first slide rails 331, clamping components 336 are arranged; both of the two clamping components 336 include a second slide rail 3362 and two sliding bodies 3361. The two second slide rails 3362 are respectively fixedly connected to the upper ends of the two rectangular plates 31. The two sliding bodies 3361 on the same side are slidably connected to the second slide rail 3362. The two second round blocks 335 and the two sliding bodies 3361 on the same side are respectively fixedly connected. On the upper ends of the four sliding bodies 3361, clamping plates 3363 are fixedly connected; on the opposite ends of the two clamping plates 3363 on the same side, a number of rubber blocks 3364 are arranged in a rectangular array.
[0030] In a specific implementation, the bending body 18 is in a state where it is located at a relatively high position and cannot perform bending operations on the steel bars. According to the model of the steel bars to be bent, the electric cylinder 32 is activated to extend the piston rod, thereby driving the second slider 332 to slide horizontally upward, thereby driving the two connecting rods 334 on the same side to rotate. The state changes from being vertically extended to being obliquely contracted. The force that causes the state of the two connecting rods 334 on the same side to change from being vertically extended to being obliquely contracted drives the two sliding bodies 3361 on the same side to slide horizontally away from each other simultaneously, so that the distance between the two clamping plates 3363 becomes larger until the two clamping plates 3363 on the same side move to a position where they cannot clamp and fix the steel bars tightly. Then, the electric cylinder 32 is turned off. By operating in this way, the other fixing component 3 is also adjusted to a state where it cannot clamp and fix the steel bars tightly;
[0031] The steel bars are horizontally placed in the two fixing components 3. At this time, the left and right sides of the steel bars are respectively located between the two clamping plates 3363 on the same side. The electric cylinder 32 is adjusted to contract the piston rod, driving the second slider 332 to slide horizontally downward, thereby causing the two connecting rods 334 on the same side to rotate. The state changes from being obliquely contracted to gradually changing in the direction of vertical extension, thereby driving the two sliding bodies 3361 to slide towards each other simultaneously, thereby driving the two clamping plates 3363 on the same side to approach the steel bars simultaneously until the steel bars are clamped and fixed tightly. Then, the electric cylinder 32 is turned off. The arranged a number of rubber blocks 3364 can play a role in increasing the friction force, making the clamping of the steel bars by the clamping plates 3363 more stable. By operating in this way, the other fixing component 3 also clamps and fixes the other side of the steel bars tightly;
[0032] After the two fixed components 3 fix both sides of the horizontally placed steel bar tightly respectively, start the motor 11 to drive the first rotating rod 13 to rotate clockwise. Under the action of the pulley 12, drive the second rotating rod 14 to rotate, thereby driving both threaded rods 15 to rotate, thereby driving the slide plate 16 to continuously slide downward, thereby driving the position of the bending body 18 to continuously move downward. The two first sliders 171 and the two chutes 172 can limit the movement of the slide plate 16 when the slide plate 16 slides downward, so that the slide plate 16 keeps moving horizontally downward, and the bending body 18 continuously moves downward until the bending operation on the lower steel bar is completed. Then adjust the motor 11 to drive the first rotating rod 13 to rotate counterclockwise, thereby driving the position of the bending body 18 to continuously move upward until the bending body 18 moves to a position where it will not obstruct the removal of the bent steel bar from the two fixed components 3, and then turn off the motor 11;
[0033] According to the above operation, adjust the electric cylinder 32 so that the clamping plate 3363 releases the clamping and fixing of both sides of the steel bar, and then take out the bent steel bar from the two fixed components 3 for subsequent work.
[0034] It should be particularly noted that the specific installation method, the connection method of the circuit and the control method of the motor 11 and the two electric cylinders 32 adopted in the present utility model are all conventional designs, and the present utility model will not elaborate in detail.
[0035] The working principle of the present utility model is:
[0036] In the initial state, the position of the bending body 18 is relatively high and cannot perform the bending operation on the steel bar. According to the steel bar model, start the electric cylinder 32 to extend the piston rod, so that the distance between the two clamping plates 3363 on the same side becomes larger, so that the steel bar cannot be clamped and fixed. In this way, both fixed components 3 are adjusted to a state where the steel bar cannot be clamped and fixed;
[0037] Place the steel bar horizontally in the fixed component 3. At this time, both sides of the steel bar are respectively in the middle positions between the two clamping plates 3363 on the same side. Start the electric cylinder 32 to contract the piston rod, so that the distance between the two clamping plates 3363 on the same side becomes smaller until the steel bar is clamped and fixed tightly. Such an operation makes the other fixed component 3 also clamp and fix the other side of the steel bar tightly;
[0038] Start the motor 11 to drive the first rotating rod 13 to rotate clockwise, so that the bending body 18 continuously moves horizontally downward until the bending operation on the lower steel bar is completed. Then start the motor 11 to drive the first rotating rod 13 to rotate counterclockwise, so that the position of the bending body 18 slides upward, and then take out the bent steel bar from the two fixed components 3.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
