[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] A steel bar bending machine for construction engineering includes a bending machine body 1, a protective component 2 fixedly connected to the top of the bending machine body 1, two auxiliary components 3 provided on the top of the bending machine body 1, a rotating disk 4 fixedly connected to the top of the bending machine body 1, and a center rod 5 fixedly connected to the top of the rotating disk 4.
[0029] The protective component 2 includes a fixing block 201. A sliding groove 202 is provided on the front side of the fixing block 201. A servo motor body 203 is fixedly connected inside the fixing block 201. A threaded rod 204 is fixedly connected to the top of the servo motor body 203. A sliding block 205 is threadedly connected to the surface of the threaded rod 204. A frame 206 is fixedly connected to the front side of the sliding block 205. A base plate 207 is provided at the bottom of the frame 206. A sliding groove 208 is provided on the top of the base plate 207. A slider 209 is slidably connected inside the sliding groove 208. The slider 209 is rotatably connected to the bottom of the base plate 207. A first circular hole 210 is provided on the top of the base plate 207.
[0030] In this embodiment: by setting up a bending machine body 1, an auxiliary component 3, a rotating disk 4, and a center rod 5, the position of the auxiliary component 3 is adjusted, and the rotating disk 4 is adjusted by the bending machine body 1 to make the rebar contact the surface of the center rod 5. With the adjustment of the bending machine body 1, the rebar is bent. By setting up a protective component 2, the rebar is prevented from deviating during the bending process by contacting the top of the rebar. By setting up a fixed block 201, a sliding groove 202, a servo motor body 203, a threaded rod 204, a sliding block 205, a frame 206, a base plate 207, a sliding groove 208, a slider 209, and a first circular hole 210, the servo motor body 203 in the fixed block 201 is connected to the threaded rod 204. When the servo motor body 203 is started, it drives the threaded rod 204 to rotate. Since the threaded rod 204 is threadedly connected to the sliding block 205, the sliding block 205 will be fixed in the fixed block 201. The front sliding groove 202 moves up and down. This design can precisely adjust the height of the frame 206 and the base plate 207 according to the actual height of the steel bar and the bending operation requirements, so that the base plate 207 can accurately contact the top of the steel bar, effectively limiting the top of the steel bar and preventing the steel bar from shifting position due to lack of constraint at the top during bending. The sliding groove 208 on the top of the base plate 207 and the sliding block 209, as well as the rotating connection design between the block 209 and the bottom of the base plate 207, give the base plate 207 a certain degree of flexibility during the limiting process. When the shape of the steel bar changes during bending, the block 209 can slide and rotate in the sliding groove 208, so that the base plate 207 can better fit the deformation of the steel bar and continuously provide a stable limiting effect for the steel bar, ensuring the smooth progress of the steel bar bending operation. The first circular hole 210 opened at the bottom of the base plate 207 can be used in conjunction with the center rod 5.
[0031] Specifically, such as Figure 3 As shown, the auxiliary component 3 includes a groove 301, a spiral rod 302 is rotatably connected inside the groove 301, and a square block 303 that mates with the groove 301 is threaded onto the surface of the spiral rod 302.
[0032] Specifically, such as Figure 3 As shown, the top of the square block 303 is provided with a mounting hole 304, and an auxiliary roller 305 is threadedly connected to the inner wall of the mounting hole 304. A protective sleeve 306 is fitted on the surface of the auxiliary roller 305.
[0033] Specifically, such as Figure 3 As shown, an auxiliary groove 307 is provided at the bottom of the inner wall of the groove 301, and an auxiliary block 308 is fixedly connected to the bottom of the square block 303. The auxiliary block 308 is located inside the auxiliary groove 307, and the side of the auxiliary block 308 away from the square block 303 is in contact with the inner wall of the auxiliary groove 307.
[0034] In this embodiment: by setting a groove 301, a spiral rod 302, a square block 303, an auxiliary roller 305, and a protective sleeve 306, the spiral rod 302 adjusts the square block 303 on the inner wall of the groove 301. Then, the auxiliary roller 305 is threadedly connected to the square block 303. Next, the protective sleeve 306 contacts the reinforcing bar, thus adjusting it according to the bending requirements of the reinforcing bar. By setting an auxiliary groove 307 and an auxiliary block 308, the square block 303 can be easily moved and adjusted on the inner wall of the groove 301.
[0035] Specifically, such as Figure 4 As shown, an electric telescopic rod body 6 is fixedly connected inside the rotating disk 4, a T-shaped groove 7 is provided on the top of the rotating disk 4, a T-shaped block 8 is slidably connected inside the T-shaped groove 7, and a limit post 9 is fixedly connected to the top of the T-shaped block 8.
[0036] Specifically, such as Figure 4 As shown, both the center rod 5 and the limiting post 9 are fitted with anti-slip sleeves 10, and both anti-slip sleeves 10 are made of rubber.
[0037] In this embodiment: by setting up the electric telescopic rod body 6, T-shaped groove 7, T-shaped block 8 and limiting post 9, the electric telescopic rod body 6 can adjust the T-shaped block 8 on the inner wall of the T-shaped groove 7, so that the limiting post 9 can move at the top position of the rotating disk 4, and cooperate with the center rod 5 to facilitate adjustment according to the diameter of different steel bars. By setting up two anti-slip sleeves 10, it is easy to contact with the steel bars and to handle the bending of the steel bars.
[0038] Specifically, such as Figure 5 As shown, a soft pad 11 is fixedly connected to the bottom of the base plate 207, and a second circular hole 12 is opened on the surface of the soft pad 11 to cooperate with the first circular hole 210.
[0039] Specifically, such as Figure 1 As shown, a support rod 13 is fixedly connected to the bottom of the bending machine body 1, and an anti-slip plate 14 is fixedly connected to the bottom of the support rod 13.
[0040] In this embodiment: by setting up a soft pad 11 and a second circular hole 12, the soft pad 11 can be used in conjunction with the first circular hole 210 to contact the top of the steel bar, so as to protect the steel bar. By setting up a support rod 13 and an anti-slip plate 14, the bending machine body 1 can be supported.
[0041] Working principle: Based on the diameter of the rebar to be bent and the bending requirements, adjust the auxiliary component 3 and rotate the spiral rod 302 in the groove 301. Since the spiral rod 302 is threadedly connected to the square block 303, the square block 303 will move within the groove 301. When the square block 303 moves, the auxiliary block 308 at its bottom slides within the auxiliary groove 307, ensuring stable movement of the square block 303. Install the auxiliary roller 305 in the mounting hole 304 at the top of the square block 303 via a threaded connection, and cover it with a protective sleeve 306, so that the auxiliary roller 305 can be properly positioned. Adjusting the position of the reinforcing bar to prepare for supporting the reinforcing bar during subsequent processing, the electric telescopic rod body 6 inside the rotating disk 4 is activated. The electric telescopic rod body 6 pushes the T-shaped block 8 to slide within the T-shaped groove 7. The limiting post 9 at the top of the T-shaped block 8 moves accordingly. By adjusting the position of the limiting post 9, it is made to cooperate with the center rod 5 to adapt to the diameter of the reinforcing bar and provide suitable space for the bending of the reinforcing bar. At the same time, the servo motor body 203 of the protective component 2 is activated. The servo motor body 203 drives the threaded rod 204 to rotate, causing the sliding block 205 to move within the sliding groove 202. Raise or lower the frame 206 to adjust the height of the bottom plate 207, ensuring it contacts the top of the reinforcing bar. Place the reinforcing bar on the bending machine body 1, ensuring it contacts the center rod 5 and the limiting post 9. Start the bending machine body 1, which drives the rotating disk 4 to rotate. The center rod 5 rotates accordingly, and the reinforcing bar begins to bend under the constraint of the center rod 5 and the limiting post 9. During bending, the reinforcing bar contacts the auxiliary roller 305. The protective sleeve 306 on the surface of the auxiliary roller 305 protects the surface of the reinforcing bar and reduces friction. 305 can also provide support when the steel bar is bent, preventing the steel bar from swaying in the horizontal direction. The base plate 207 of the protective component 2 slides and rotates in the groove 208 through the slider 209 to adapt to the bending deformation of the steel bar and continuously limit the top of the steel bar to prevent the top of the steel bar from deviating. The soft pad 11 and the second circular hole 12 at the bottom of the base plate 207 contact the top of the steel bar, which can not only prevent the steel bar from being scratched, but also enhance the limiting effect. The support rod 13 and the anti-slip plate 14 at the bottom of the bending machine body 1 play a supporting and anti-slip role, ensuring the stability of the bending machine during operation.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
