[0021] In order to improve the stability of the movement of the first pneumatic clamp 32 and the stability of the opening and closing of the clamp plate 35, as an embodiment, a guide mechanism 9 is further included, the guide mechanism 9 includes a guide rod 91 and a movable seat 92 that is slidably connected with the guide rod 91, the guide rods 91 are arranged in parallel in three, and the three guide rods 91 are extended along the feeding direction.

[0022] Similarly, in order to improve the stability of the opening and closing of the clamping plate 35 of the second pneumatic clamp 33 , a second connecting seat 38 slidably connected to the opening and closing direction of the clamping plate 35 of the first pneumatic clamp 32 is fixed on the mounting platform 21 .

[0023] As an implementation method, Figure 2As shown, the pneumatic mechanism 36 includes a fixed plate 364, a vertical fixed rod 363, a clamping rod 362 and a second cylinder 361 for controlling the opening and closing of the clamping rod 362.

The telescopic movement of the third cylinder 53 can drive the push plate 52 to move, thereby pushing out a row of steel bars.

[0025] The working principle of the utility model is:

[0026] The steel bars to be bent are arranged on the material box, and the first moving mechanism 6 is used to drive the material box to move horizontally so that one of the material discharge grooves corresponds to the first limiting groove 7. The third cylinder 53 drives the push plate 52 to move, and pushes the multiple steel bars on the material discharge groove to extend to the first limiting groove 7. Due to the limiting effect of the first limiting groove 7, the stable arrangement of the multiple steel bars can still be guaranteed. Then, the clamping plate 35 of the second pneumatic clamp 33 is used to clamp the multiple steel bars extending out of one end of the first limiting groove 7, and is pushed to the bending mechanism 2 for bending under the drive of the second moving mechanism 34. During the bending process, the clamping plate 35 of the second pneumatic clamp 33 can effectively clamp the multiple steel bars to be bent on the fixed column, and cooperate with the second limiting groove 8 for further limiting, to ensure the stability of the clamping of the multiple steel bars during the bending process, and to ensure the bending accuracy. After bending, the bent steel bar is manually removed.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
