[0024] A steel bar bending machine, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a base plate 10; an active pressure roller 11 movably mounted on the top surface of the base plate 10 for squeezing and pushing the steel bar to deform, and two limiting bodies 12 symmetrically arranged on the top surface of the base plate 10 for limiting the bending angle of the steel bar; the limiting body 12 adjusts and locks the angle through a locking structure, and the locking structure includes a through hole 30, a rotating shaft 31 and a thrust rod 33. The wall surface of the limiting body 12 is provided with a through hole 30, and the rotating shaft 31 passes through the through hole 30 and is rotatably connected to the base plate 10. The thrust rod 33 is elastically connected to the rotating shaft 31 and is clamped with the base plate 10 to lock the angle of the limiting body 12. The active pressure roller 11 is pushed and maintained in linear displacement by the driving structure. The limiting body 12 forms an angle iron structure with an L-shaped cross section. The through hole 30 is opened at the top of the vertical part of the limiting body 12, and the through hole 30 passes through the limiting body 12. The rotating shaft 31 passes through the through hole 30 It is fixedly connected to the limiting body 12, and the length of the rotating shaft 31 is greater than the height of the limiting body 12. In the present embodiment, by adjusting the angles of the two symmetrically distributed limiting bodies 12, when the active pressure roller 11 approaches the two limiting bodies 12, the limiting body 12 pushes the steel bar to bend and form an arc-shaped bend. When the extended part of the steel bar hits the two limiting bodies 12, the bending angle of the steel bar is limited. The limiting body 12 with adjustable angle can adjust the bending angle of the steel bar within a certain range, thereby having better adjustability and production adaptability. Specifically, when adjusting the angle of the limiting body 12, the thrust rod 33 is pushed to slide, and the thrust rod 33 is separated from the base plate 10. After the limiting body 12 is rotated to adjust the position, the thrust rod 33 is released, and the thrust rod 33 is again engaged with the base plate 10 to lock the angle of the limiting body 12, which is easy to operate.

[0025] like Figure 4 As shown, the locking structure also includes a horizontal groove 32. Two horizontal grooves 32 are symmetrically provided on the end surface of the rotating shaft 31. The same thrust rods 33 are arranged in the two horizontal grooves 32. A spring is also provided in the horizontal groove 32. The thrust rod 33 is elastically connected to the rotating shaft 31 through the spring. The horizontal groove 32 forms a rectangular notch. The horizontal groove 32 runs through the entire rotating shaft 31. The thrust rod 33 is adapted to the horizontal groove 32 and slides in the horizontal groove 32. The two ends of the spring are fixedly connected to the thrust rod 33 and the inner wall surface of the rotating shaft 31 respectively. By setting the horizontal groove 32 and utilizing the thrust given to the thrust rod 33 by the spring in the horizontal groove 32, the thrust rod 33 and the base plate 10 are automatically locked.

[0026] like Figure 2 and Figure 5As shown, the locking structure also includes a rotation hole 34 and a side groove 35. The top surface of the base plate 10 is provided with a rotation hole 34, and a plurality of side grooves 35 are equidistantly provided on the inner wall surface of the rotation hole 34. The side grooves 35 are adapted to the thrust rod 33, and the rotation hole 34 is adapted to the rotating shaft 31. The thrust rod 33 can be inserted into the side grooves 35 at different positions to lock the angle of the limiting body 12. The rotating shaft 31 is limited by the rotation hole 34 so that the rotating shaft 31 maintains circular rotation. Multiple side grooves 35 can clamp the thrust rod 33. Multiple side grooves 35 are distributed in a circular array. The two symmetrically distributed thrust rods 33 can better provide limiting for the rotating shaft 31, and the locking strength is higher. In order to ensure the angle adjustment effect of the limiting body 12, a scale is also provided on the top surface of the base plate 10 to display the specific angle of the limiting body 12.

The sliding channel 20 is provided on the top surface of the substrate 10, and the slider 21 slides in the perforation 30. The active pressure roller 11 is rotatably connected to the slider 21, and the screw rod 22 is rotatably connected to the substrate 10 and threadedly connected to the slider 21. The slider 21 and the sliding channel 20 cooperate with each other. A threaded hole is provided on the wall surface of the slider 21, and the screw rod 22 is connected to the threaded hole of the slider 21. The end surface of the screw rod 22 is rotatably connected to the substrate 10. By rotating the screw rod 22, the screw rod 22 drives the slider 21 to slide in the perforation 30, so that the active pressure roller 11 can maintain linear displacement to push the steel bar to deform. A motor can be installed on the wall surface of the substrate 10, and the motor output shaft is connected to the screw rod 22 to realize the driving of the screw rod 22. With the limitation of the two limiting bodies 12, the steel bar bending step is optimized, the bending effect is good, and the efficiency is high.

[0028] The working principle of the utility model is as follows: pinch the two thrust rods 33, the thrust rods 33 slide in the horizontal grooves 32 and squeeze the springs to deform, the thrust rods 33 are disengaged from the side grooves 35 at the corresponding positions, and after the limiting body 12 is rotated to a specified angle, the thrust rods 33 are released, the springs push the thrust rods 33 to reset and snap into the side grooves 35 at the corresponding positions, so as to achieve the angle adjustment of the limiting body 12;

[0029] The screw rod 22 is rotated to drive the slider 21 to slide in the perforation 30 , so that the active pressure roller 11 can maintain linear displacement to push the steel bar to deform, and the bending arc is completed when the extended part of the steel bar contacts the limiting body 12 .
