In specific implementation, selection and adaptive adjustment of the design should be made according to actual needs.
[0037] In this embodiment, the steel bar bending device includes a bracket 10 and a bending mechanism, and the bending mechanism includes a fixed baffle 100, a work station disk 200, a movable disk 400, a push column 500 and a push rod 600. The fixed baffle 100 is fixedly connected to the bracket 10, the movable disk 400 is coaxially arranged with the work station disk 200, the radius of the movable disk 400 is greater than the radius of the work station disk 200, and a connecting shaft 300 is fixedly provided at the center of the movable disk 400. One end of the work station disk 200 and the fixed baffle 100 are both rotatably connected to the connecting shaft 300. The fixed baffle 100 is provided with a support seat 110, and the support seat 110 is provided with a support for accommodating The steel bar accommodating groove 111, the outer peripheral surface of the work station 200 is provided with a guide groove 210, the notch of the steel bar accommodating groove 111 is opposite to the notch of the guide groove 210, the steel bar accommodating groove 111 is used to accommodate a partial segment of the first end of the steel bar to be bent, the groove wall surface of the steel bar accommodating groove 111 is used to support the first end of the steel bar, relative to the bracket 10, the position of this end of the steel bar is fixed, the guide groove 210 guides the middle section of the steel bar, the groove wall of the guide groove 210 can limit the outer surface of the steel bar to avoid large distortion of the steel bar during the bending process, and the inner wall of the guide groove 210 becomes the fulcrum of the middle part of the steel bar. The push column 500 is arranged at an eccentric position of the movable disk 400, and the distance between the axis of the push column 500 and the movable disk 400 is greater than the radius of the station disk 200, and the push column 500 is perpendicular to the disk surface of the movable disk 400; the push rod 600 is fixedly connected to the outer peripheral surface of the movable disk 400; in this way, when an external force is applied to the push rod 600, the push rod 600 can drive the movable disk 400 and the push column 500 to rotate, and the outer surface of the push column 500 can push the other end of the steel bar, so that the second end of the steel bar is bent relative to the first end of the steel bar, so that a certain bending angle is formed between the first end and the second end of the steel bar. In this way, the steel bar bending device can achieve the bending of the steel bar through the bending mechanism.
[0038] The steel bar bending device also includes an angle adjustment mechanism, which includes a limit stop frame 700 and a movable stop frame 800. One end of the limit stop frame 700 is rotatably connected to the other end of the fixed stop frame 100, one end of the movable stop frame 800 is fixedly connected to the connecting shaft 300, and the other end of the movable stop frame 800 is used to adapt and connect with different positions in the extension direction of the limit stop frame 700. When the push rod 600 drives the movable disk 400 and the push column 500 to rotate, the second end of the steel bar rotates around the connecting shaft 300. In this process, the movable block frame 800, the push column 500, the push rod 600 and the movable disk 400 all rotate at the same angle and at the same time. When the movable block frame 800 stops rotating, the push column 500 can no longer continue to rotate and apply pressure to the second end of the steel bar. Therefore, by controlling the movable block frame 800 to be connected to different positions of the extension direction of the limit block frame 700, the limit block frame 700 can limit the movable block frame 800 at the end position of the rotation of the movable block frame 800, so that the movable block frame 800 at the end position of the rotation cannot continue to rotate, thereby controlling the rotation angle of the second end of the steel bar driven by the push column 500 relative to the first end of the steel bar. That is, when the limit block frame 700 is connected to the other end of the movable block frame 800 at different positions in the extension direction, the corresponding steel bar presents a bending angle of different angle values. In this way, the steel bar bending device can pre-set and control the bending angle of the steel bar through the angle adjustment mechanism, thereby ensuring the accuracy of the steel bar bending angle and improving the qualified rate of the steel bar bending. In specific implementation, the steel bar bending process is as follows:
[0039] It is known that the steel bar needs to be bent at an angle of α, and when the bending angle of the steel bar is α, the position-limiting retaining frame 700 can be adapted and connected with the other end of the movable retaining frame 800 at P in the extension direction. In the initial state, that is, before the steel bar is bent, the steel bar is in a straight line. At this time, the angle between the movable retaining frame 800 and the fixed retaining frame 100 is the smallest, and the distance between the end of the movable retaining frame 800 away from the work station 200 and the end of the fixed retaining frame 100 away from the work station 200 is the smallest. The other end of the movable retaining frame 800 cannot be connected to the position P of the position-limiting retaining frame 700, and the position-limiting retaining frame 700 cannot limit the movable retaining frame 800. When the bending work starts, the first end of the steel bar is placed in the steel bar receiving groove 111, and the middle section of the steel bar is placed in the guide groove 210. The pushing rod 600 is operated to rotate the pushing rod 600. Driven by the pushing rod 600, the pushing column 500, the movable disk 400 and the movable baffle 800 rotate at the same time until the pushing column 500 is against the second end of the steel bar. The rotation angle at this time is recorded as 0°. The pushing rod 600 continues to rotate and force is applied to the pushing rod 600. The pushing rod 600 pushes the second end of the steel bar and causes the second end of the steel bar to begin to bend. At the same time, the pushing rod 600, the pushing column 500, the movable disk 400 and the movable baffle 800 continue to rotate, and when the rotation angle is β, where β=180°-α, the P of the limit baffle 700 can be adapted and connected to the other end of the movable baffle 800, indicating that the bending angle of the steel bar has reached the preset bending angle α.
[0040] To sum up, the steel bar bending device can realize the bending of steel bars through the bending mechanism, and can pre-set and control the bending angle of the steel bars through the angle adjustment mechanism. The steel bar bending device has a simple structure and is easy to operate. By adapting and connecting the other end of the movable baffle frame with different positions in the extension direction of the limit baffle frame, the bending angle of the steel bars can be controlled and adjusted to ensure the accuracy of the bending angle of the steel bars and improve the qualified rate of the steel bar bending.
[0041] See also Figures 1 to 3 In some embodiments, the other end of the limit stop frame 700 is provided with a plurality of tooth grooves 710 arranged along the extension direction of the limit stop frame 700, and the other end of the movable stop frame 800 is provided with a positioning rod 810, and the positioning rod 810 is used to engage with one of the tooth grooves 710. In this embodiment, the positioning rod 810 of the movable stop frame 800 can be adapted to engage with one of the plurality of tooth grooves 710 in the extension direction of the limit stop frame 700, so that the limit stop frame 700 limits the rotation position of the movable stop frame 800. In addition, the limit stop frame 700 and the movable stop frame 800 are adapted to be connected in a manner of engaging the tooth grooves 710 with the positioning rod 810, and the connection method is reliable and the structure is simple.
[0042] In a specific implementation, the multiple tooth grooves 710 of the limit stop frame 700 correspond to different preset bending angles of the steel bars respectively. In implementation, scale marks corresponding to the preset bending angles can be set above the tooth grooves 710.
[0043] In some embodiments, the movable disk 400 is located below the work disk 200; the angle adjustment mechanism also includes a dial 900, which is located between the movable disk 400 and the work disk 200, the dial 900 is coaxial with the work disk 200, and the dial 900 is fixedly connected to the fixed bracket 100, and the radius of the dial 900 is greater than the radius of the work disk 200 and smaller than the radius of the movable disk 400.
[0044] In this embodiment, because the scale plate 900 is coaxial with the work station 200 and the scale plate 900 is fixedly connected to the fixed baffle 100, the scale plate 900 is fixed; when the push rod 600 rotates, the movable baffle 800 rotates at the same time, and the movable baffle 800 rotates to a certain extent relative to the scale plate 900, and its rotation angle is complementary to the bending angle of the steel bar. Therefore, during the bending process, by observing the rotation angle of the movable baffle 800 relative to the scale plate 900, the accurate bending angle of the steel bar can be known at all times. In a specific implementation, when the second end of the steel bar is pushed to bend to a complementary angle close to the preset bending angle, the rotation speed of the push rod 600 can be slowed down to avoid excessive bending of the steel bar due to the failure of timely adaptation and connection between the other end of the movable baffle 800 and the other end of the limit baffle 700.
[0045] See also Figure 3 In some embodiments, both the reinforcement groove 111 and the guide groove 210 are semicircular grooves. In this way, it is more suitable for the outer surface shape of most steel bars, which is conducive to increasing the contact area between the steel bars and the groove walls of the reinforcement groove 111 and the guide groove 210, and improving the support of the reinforcement groove 111 and the guide groove 210 to the first end and the middle of the steel bars.
[0046] See also Figures 1 to 3 In some embodiments, the extension direction of the push rod 600 passes through the axis of the movable disk 400 and the axis of the push column 500. In this way, the rotation angle of the push rod 600 is consistent with the rotation angle of the movable disk 400 and the push column 500, which is conducive to saving the force acting on the push rod 600, and the steel bar bending device is more labor-saving.
[0047] See also Figure 1 and Figure 2In some embodiments, the movable baffle 800 includes a first plate 820 and a second plate 830 arranged in the up-down direction, and the first plate 820 and the second plate 830 are fixedly connected by a connecting column 840 to improve the structural strength of the movable baffle 800; one end of the first plate 820 is fixedly connected to the connecting shaft 300, and one end of the second plate 830 is provided with an avoidance portion 850, and the avoidance portion 850 is fixedly connected to the disk surface of the fixed disk, and the avoidance portion 850 is provided with an avoidance groove 851, and the notch of the avoidance groove 851 is opposite to the notch of the guide groove 210, and the avoidance groove 851 can prevent the second plate 830 from interfering with the steel bar, and the avoidance groove 851 is used to insert the steel bar.
[0048] See also Figures 1 to 3 In some embodiments, the width of the steel bar groove 111 is equal to the width of the guide groove 210, and the steel bar groove 111 and the guide groove 210 are located on the same horizontal plane. In this way, the first end of the steel bar and the middle section are ensured to be placed horizontally, so as to avoid the steel bar from being twisted during the bending process and improve the bending effect of the steel bar.
