A non-slip sleeve 46 is sleeved on the outer end side wall of the operating rod 26, because a large force is required when bending the flat steel. If the anti-slip sleeve 46 is not added, it is easy to slip during the operation, and the anti-slip sleeve 46 can be It has a non-slip effect and is easy to operate.

In use, the weight 14 is pulled outward, and the telescopic rod is extended outward by the pulling force to increase the distance between the weight 14 and the base. The telescopic cylinder 16 is controlled to extend to the right by the control device and drives the two first lift cylinders 17 together with the components thereon to move rightward along the chute 4 to a suitable position. Before bending, one of the clamping discs 29 on the bending adjustment device is pushed outward, and the elastic force of each of the clamping springs 31 on the corresponding side is overcome by the external force and the guiding rods on the corresponding side are made. 30 outward movement, when the gap between the two clamping springs 31 is greater than the width of the processed flat steel, the lower end of the flat steel is passed through the insertion hole 32, at this time, the clamping of the clamping circular plate 29 is stopped, in two The elastic force of the side clamping spring 31 will Clamp the flat steel and continue to press down the flat steel so that the lower end of the flat steel is lower than the fixed baffle 19. After the detection switch 23 detects the flat steel, the control device controls the two clamping cylinders 21 to close each other and pass the clamping plate. 22 The lower end of the flat steel is clamped, and the control device can adjust the clamping force of the clamping cylinder 21 according to the inductor 24 on the two clamping plates 22. At this time, the hands are released, and the flat steel does not continue to fall downward under the clamping action of the clamping spring 31 and the clamping cylinder 21. Holding the anti-slip sleeve 46 of the operating rod 26 and pressing down the operating rod 26 with force, the rotation of the operating rod 26 under the action of the external force will drive the rotating tube to rotate around the fixed shaft 3, and the left side wall of the lower end of the flat steel under the action of external force Abutting on the fixed baffle 19, the middle portion of the flat steel in the insertion hole 32 is inclined to the right by the external force, and the side of the flat steel in the insertion hole 32 is opposite to the guide support plate 28. Then, the other side of the flat steel will abut against the outer side wall of the rotating tube 25, and continuing to press the operating rod 26 downward will bend the flat steel. By observing the corresponding positional relationship between the indicating block 34 and the angle line on the dial and pressing the operating lever 26 downward, the flat steel of different bending angles can be obtained, and the versatility is strong. In the process of pressing down the operating rod 26, a large force is required, because the weight 14 is pulled out and the distance from the base is long, in which case the weight 14 can function as a counterweight. The base is more stable when the flat steel is bent hard. In addition, the difference in length between the two sides of the flat steel can be achieved according to the difference in the length of the flat steel pressed downward, which can be better applied to the construction of the project. After the bending of the flat steel is completed, the two clamping cylinders 21 are controlled to be reset by the control device, and the components on the telescopic cylinder 16 are controlled to move to the left and reset, and the lower end of the bent flat steel is in a free state. Then, the operating lever 26 is held by the operating lever 26 to push the operating lever 26 backward. Since the bent flat steel has only the clamping action of the clamping spring 31, the control device controls the electromagnet base 10 to be energized and generates a strong magnetic force, which is attracted by the magnetic force. The flat steel will overcome the clamping force of the clamping spring 31 and will be adsorbed and fixed on the sensing plate 13 after falling through the drop hole 6. When the sensing plate 13 detects the falling of the flat steel, the information is fed back to the control device, and the control device controls the positioning and adjusting the drilling device to work, and the moving motor tube 40 is adjusted to be adjusted above the sensing plate 13 by the guiding motor 38 and the adjusting motor. The position is detected by the infrared detecting block 43 and the monitoring device 41 monitors and feeds back to the control device to detect the position and contour of the flat steel. After determining the position and contour of the flat steel, the control device continues to control the adjustment of the moving square tube 40 to a suitable position, and the second lifting cylinder 42 projects downwardly and drives the drilling motor 44 and the drill bit 45 to descend for drilling, according to the control device. The profile of the flat steel being monitored and the requirements during construction are used to control the spacing and depth of the borehole. After drilling is completed, the control unit controls the various components to reset and wait for subsequent work. The device has the advantages of simple structure, reasonable design and simple operation, and the flat steel profile can be quickly bent, or the flat steel scrap on the construction site can be quickly bent, which saves time and labor, has good bending forming effect, and can be Need to, the flat steel to complete the required bending angle, in the large area construction can ensure the flatness of the place, to ensure the construction quality. In addition, after the folding, the bent flat steel can be automatically drilled, which saves the operation steps in the subsequent construction. The adjusting device can be clamped according to the thickness of the flat steel, which has strong versatility and more effectively meets people's needs.
