[0022] In order to solve the technical problem that the existing steel bar bending machine is unable to simultaneously bend both ends of steel bars of different lengths, the utility model provides a steel bar bending machine that can simultaneously bend both ends of steel bars of different lengths.

The axis of the bending rod 26 is parallel to the axis of the pressure rod 25. When one end of the steel bar is placed on the pad 22, the pressure rod 25 is driven by the telescopic member 23 to extend to the top of the pad 22, so that the driving member 24 drives the bending rod 26 to rotate around the axis of the pressure rod 25 to bend the steel bar.

[0024] In this embodiment, a plurality of movable rollers 11 are provided at the bottom of the workbench 1. It should be noted that at least one of the movable rollers 11 has a braking function.

[0025] In one embodiment, both bending units 2 are movably connected to the top of the workbench 1. In addition, an adjustment unit 3 is provided on the workbench 1, and the adjustment unit 3 includes a forward and reverse screw rod 31. The forward and reverse screw rod 31 is rotatably provided on the workbench 1, and the two threaded parts of the forward and reverse screw rod 31 are respectively threadedly connected to the two base plates 21.

[0026] Specifically, a rotating hand wheel 32 is provided at one end of the forward and reverse screw rod 31 . By rotating the hand wheel 32 to drive the forward and reverse screw rod 31 to rotate, the two bottom plates 21 can be driven closer or farther away to accommodate steel bars of different lengths.

[0027] In this specific embodiment, the telescopic member 23 includes an electric push rod 231 and a guide seat 232. The guide seat 232 is fixed on the base plate 21. The electric push rod 231 is fixed on the guide seat 232. The pressure rod 25 slides through the guide seat 232. The output end of the electric push rod 231 is connected to the pressure rod 25.

[0028] It should be noted that the pressure rod 25 and the bending rod 26 have high strength. Specifically, the pressure rod 25 and the bending rod 26 are both made of high-carbon steel rods.

[0029] Furthermore, the electric push rod 231 can drive the pressure rod 25 to retract into the guide seat 232, making it convenient for the operator to place one end of the steel bar on the pad; in addition, the length of the pressure rod 25 extending outside the guide seat 232 is equal to the length of the pad.

[0030] In one embodiment, five steel bars can be placed between the two spacers at the same time, that is, the steel bar bending machine can bend both ends of the five steel bars at the same time, thereby improving the bending efficiency of the steel bars.

[0031] In this specific embodiment, the driving member 24 includes a forward and reverse motor 241 and a turntable 242. The forward and reverse motor 241 is fixed on the base plate 21.

The mounting frame 41 is fixedly connected to the top of the workbench 1, and at least one pneumatic cylinder 42 is connected to the mounting frame 41. The output end of the pneumatic cylinder 42 is fixedly connected to the pressing plate 43. When the steel bar is spanned between the two pads 22, the pneumatic cylinder 42 can drive the pressing plate 43 to contact the middle part of the steel bar; further, an elastic rubber pad is provided on the lower surface of the pressing plate 43.

[0033] In addition, a support block 5 is fixedly provided on the workbench 1 between the two bottom plates 21 , and the highest point of the support block 5 and the cushion block 22 are located on the same plane.

[0034] It should be noted that the pressure plate 43 is driven by the pneumatic cylinder 42 to squeeze the steel bar so that the middle part of the steel bar is fixed between the pressure plate 43 and the support block 5, which can effectively prevent the steel bar from moving when it is bent.

[0035] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0036] According to the required length of the bent steel bars, the distance between the two base plates 21 is adjusted by rotating the forward and reverse screw rods 31, and the two ends of the multiple steel bars are aligned. The opposite ends of the multiple steel bars are respectively placed on the two pads 22, and the two electric push rods 231 respectively push the two pressing rods 25 to extend above the two pads 22. At the same time, the pneumatic cylinder 42 drives the pressing plate 43 to press the steel bars, and the two forward and reverse motors 241 respectively drive the two bending rods 26 to rotate to bend the two ends of the steel bars.
