[0002] Steel bar is a very common building material with very high rigidity. Usually, when building a house, steel bars are needed to make keels, and then concrete is poured. When using steel bars, they often need to be bent in order to match the corresponding buildings, so as to achieve the same angle as the concrete pouring building. At present, steel bars are mostly bent by bending machines. After putting the steel bars into the bending machine, hold the handle and rotate the bending part to bend the steel bars. Since the bending of the steel bars generates a large deformation force, the steel bars are easy to burst out to both sides of the outside of the bending machine when bending, thereby causing injuries to the user. At the same time, in order to increase the speed of bending multiple steel bars during construction on the construction site, no cover that needs to be frequently opened or closed is set on the outside of the bending machine to protect the user.

[0016] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The outside of the bending collar 12 is provided with a clamping assembly for fixing the bent end of the steel bar, and the clamping assembly includes a hoop 20, a support sleeve 21 and a pressing plate 23 for placing the bent end of the steel bar. The hoop 20 is fixedly connected to the outside of the bending collar 12, and the support sleeve 21 is fixedly connected to the side of the outside of the bending collar 12 close to the hoop 20. The pressing plate 23 movably penetrates the support sleeve 21 and the hoop 20 and extends into the inside of the hoop 20.

At the same time, before placing it into the hoop 20, the pushing plate 22 is retracted and not moved to make the pressing plate 23 shrink into the inside of the supporting sleeve plate 21, and one end of the steel bar is completely placed inside the hoop 20. At this time, the pushing plate 22 is released, and the elastic force generated by the sleeve spring 26 drives the pressing plate 23 and the resist plate 24 to squeeze the surface of the steel bar inside the hoop 20.

[0017] See also Figure 2A storage component for placing steel bars is provided on the outside of the bending processing table 10, and the storage component includes a steel bar placement box plate 50, which is fixedly connected to the side of the outside of the bending processing table 10. The outside of the steel bar placement box plate 50 is provided with an outer notch 51 for conveniently taking out the steel bars. By placing multiple steel bars inside the steel bar placement box plate 50, and taking out the steel bars from the outer notch 51 when the steel bars need to be bent, the effect of quickly placing and taking out the steel bars is achieved.

[0018] Working principle: When in use: the first step is to put one end of the steel bar into the hoop 20, and at the same time, before putting it into the hoop 20, use the retracted push plate 22 to retract the pressure plate 23 into the support sleeve 21, and put one end of the steel bar completely into the hoop 20. At this time, release the push plate 22 and the elastic force generated by the sleeve spring 26 drives the pressure plate 23 and the abutment plate 24 to squeeze the surface of the steel bar into the hoop 20, so as to achieve the effect of stably fixing one end of the steel bar between the bending ring 12 and the hoop 20.

[0019] In the second step, after fixing one end of the steel bar inside the hoop 20, the other end of the steel bar is overlapped on the outside of the drawstring 34, and the handle 13 is held to drive the end of the steel bar located in the hoop 20 to bend. When one end of the steel bar is bent, downward pressure is applied to the other end, and the other end of the steel bar approaches the pressing ring 16 and drives the drawstring 34 to press downward. After the other end of the steel bar is placed and contacts the surface of the pressing ring 16, the tension applied by the drawstring 34 to the line plates 33 on both sides and the protective baffles 30 on both sides makes the protective baffles 30 on both sides respectively use the two rotating rods 32 as the center. The centers of the steel bars are rotated close to each other to close, and the protective baffles 30 on both sides are rotated to close on the outside of the steel bars, so as to protect the outside of the steel bars when the steel bars are bent. At the same time, after the steel bar bending process is completed, the bending ring 12 is driven by the handle 13 to rotate and reset, and the protective baffles 30 on both sides are automatically rotated and separated with the rotating rods 32 on both sides as the center due to gravity. At this time, the bent steel bars can be quickly taken out, thereby achieving the effect of protecting the steel bars during the bending process while quickly processing the steel bars, and effectively protecting the safety of the users.

[0020] The third step is to rotate the turntable 41 to drive the screw 42 to rotate inside the support beam 40, and the screw 42 is spirally transmitted inside the support beam 40 in the direction of the bending ring 12. The screw 42 drives the circular plate 43 to spirally transmit inside the circular groove 45 and pushes the connecting plate 44 in the direction of the bending ring 12. The connecting plate 44 drives the short plates 15 on both sides to make the pressure ring 16 move synchronously in the direction of the bending ring 12. By adjusting the distance between the pressure ring 16 and the bending ring 12, the device can be adapted to different diameters of steel bars for bending.
