The cylinder 61 is provided in the middle of the front side of the top of the shell 1, and the push rod 62 is provided on the rear side of the telescopic rod of the cylinder 61. Racks 63 are slidably provided on the left and right sides of the push rod 62. First springs 64 are provided between the front side of the rack 63 and the push rod 62, and the first springs 64 are all wound around the outside of the push rod 62.

[0038] The discharging assembly 7 includes a guide rod 71, a first support rod 72, a baffle 73 and a second spring 74. The guide rod 71 is symmetrically arranged on the upper rear part of the inner wall of the shell 1. The front end of the guide rod 71 is connected to the rear side of the support frame 3. The front side of the guide rod 71 is slidably provided with a first support rod 72. A baffle 73 is arranged between the front lower part of the first support rod 72. When people put steel bars into the shell 1, the baffle 73 can support the steel bars. When the baffle 73 moves backward, the steel bars can fall down, thereby completing the discharging work. The second spring 74 is wound around the guide rod 71, and the two ends of the second spring 74 are respectively connected to the first support rod 72 and the shell 1.

[0039] When people need to use the building material steel bar bending equipment, first put the steel bar into the shell 1 through the round hole, so that the steel bar passes through the lower part of the two turntables 4, the baffle 73 can block the bottom of the steel bar, so as to support the steel bar, and the turntable 4 can also play a certain role in fixing the steel bar, and then start the cylinder 61 to control the extension of the telescopic rod of the cylinder 61, so as to drive the push rod 62 to move backward, and the push rod 62 drives the first spring 64 and the rack 63 to move backward.

Under the action of gravity, the bent steel bar can fall down into the collection frame 2, and then the telescopic rod of the control cylinder 61 is shortened, thereby driving the push rod 62 to move forward and reset. At this time, the first spring 64 first recovers to its original state. When the push rod 62 is separated from the first support rod 72, the second spring 74 recovers to its original state, driving the first support rod 72 to move forward and reset. The first support rod 72 drives the baffle 73 to move forward and reset. When the first spring 64 is completely restored to its original state, the push rod 62 drives the first spring 64 and the rack 63 to move forward and reset. The rack 6 3 drives the spur gear 53 to reverse, thereby driving the transmission shaft 51 and the first bevel gear 52 to reverse, the first bevel gear 52 drives the second bevel gear 54 to reverse, and the second bevel gear 54 drives the turntable 4 to reverse and reset. When the rack 63 is separated from the spur gear 53, the spur gear 53 stops rotating, so that the turntable 4 stops rotating. Repeat the above operation to bend the steel bar again. When people do not need to use the building material steel bar bending equipment, close the cylinder 61, then pull the collection frame 2 forward, take out the steel bars in the collection frame 2, and finally push the collection frame 2 backward to reset.

[0041] It also includes a disengagement component 9, which includes a first connecting rod 91, a sixth spring 92 and a second connecting rod 93. The first connecting rod 91 is slidably provided in the middle of the rear side of the upper part of the support frame 3, and a sixth spring 92 is provided between the top of the first connecting rod 91 and the support frame 3. A second connecting rod 93 is provided on the upper part of the first push block 87, and the second connecting rod 93 is in contact with the first connecting rod 91. When the first connecting rod 91 moves upward, it can drive the second connecting rod 93 and the first push block 87 to move upward, so that the second fixed block 82 can move forward to loosen the steel bar.

[0042] When people put the steel bar into the shell 1 through the round hole, the steel bar is located between the first fixing block 81 and the second fixing block 82. When the push rod 62 moves backward, it drives the second support rod 84 to move backward, the second support rod 84 drives the support block 85 to move backward, the support block 85 drives the first push block 87 to move backward, the first push block 87 squeezes the second fixing block 82 to move backward, the third spring 83 is compressed, so that the first fixing block 81 and the second fixing block 82 can clamp the middle part of the steel bar. When the second fixing block 82 can no longer move backward, the second fixing block 82 can move backward. When the baffle plate 73 moves backward, the first push block 87 and the support block 85 stop moving, the second support rod 84 continues to move backward, the fourth spring 86 is compressed, and when the baffle plate 73 moves backward, the baffle plate 73 no longer blocks the bottom of the steel bar. When the baffle plate 73 contacts the first connecting rod 91, the baffle plate 73 squeezes the first connecting rod 91 to move upward, the sixth spring 92 is compressed, the first connecting rod 91 drives the second connecting rod 93 to move upward, the second connecting rod 93 drives the first push block 87 to move upward, the fifth spring 88 is compressed, and when the first push block 87 is separated from the second fixing block 82, the first push block 87 is moved upward. When the push rod 62 moves forward and resets, the third spring 83 returns to its original state, driving the second fixing block 82 to move forward and reset, so that the first fixing block 81 and the second fixing block 82 loosen the steel bars, and the bent steel bars can fall down into the collection frame 2. At the same time, the fourth spring 86 returns to its original state, driving the first push block 87 to move backward, and the first push block 87 drives the support block 85 to move backward. When the push rod 62 moves forward and resets, it drives the second support rod 84 to move forward and reset, and the second support rod 84 drives the support block 85 to move forward and reset, and the support block 85 drives the first push block 87 to move backward. The first push block 87 moves forward to reset, and at the same time, the baffle 73 moves forward to reset, the baffle 73 is separated from the first connecting rod 91, the sixth spring 92 returns to its original state, driving the first connecting rod 91 to move downward to reset, so that the first connecting rod 91 is separated from the second connecting rod 93. At this time, the top of the second fixed block 82 presses against the bottom of the first push block 87, and the fifth spring 88 cannot return to its original state. When the first push block 87 is completely reset, the second fixed block 82 no longer presses against the first push block 87, and the fifth spring 88 returns to its original state, driving the first push block 87 to move downward to reset.

[0043] It also includes a pushing assembly 10, which includes a third connecting rod 101, a seventh spring 102, a second pushing block 103, an eighth spring 104, a clamping rod 105 and a ninth spring 106.

When the baffle plate 73 moves backward, the baffle plate 73 no longer blocks the bottom of the steel bar. When the baffle plate 73 contacts the third connecting rod 101, the third connecting rod 101 is squeezed to move downward. The seventh spring 102 is compressed. Since the clamping rod 105 clamps the second push block 103, the second push block 103 cannot move downward. The eighth spring 104 is compressed. When the second fixing block 82 moves forward to reset, the clamping rod 105 is driven to move forward to reset.
