The rectangular block 9 is fixedly installed on the output shaft of the hydraulic cylinder 6; the rectangular block 9, the rectangular rod 12, the vertical guide rods 10, the springs 11 and the stopping blocks 13 are arranged in cooperation. The hydraulic cylinder 6 is used to drive the rectangular block 9 to move downward. The rectangular block 9 drives the punching cutter head 5 to move downward through the rectangular rod 12. The rectangular block 9 drives the inverted U-shaped pressing seat 7 to move downward synchronously through the springs 11. The inverted U-shaped pressing seat 7 drives the two arc-shaped anti-slip rubber sheets 16 to press downward on the building steel bars. The continuously downward moving rectangular block 9 compresses the springs 11. The compressed springs 11 are used to drive the inverted U-shaped pressing seat 7 to tightly press and fix the building steel bars. The continuously downward moving punching cutter head 5 moves downward to perform punching and blanking work, achieving the effect of single-drive integrated automatic fixing and punching and blanking of building steel bars.

[0030] The usage method of this embodiment is as follows: First, place the building steel bars on the tops of the two steel bar supports 2. Adjust the position of the T-shaped limit seat 17 according to the length required for punching and blanking. When adjusting, start the electric telescopic rod 18 in the forward direction to drive the T-shaped limit seat 17 to move to the right, changing its blocking and limiting position. After adjusting to the appropriate position, turn off the electric telescopic rod 18 and place the right end of the building steel bar against the right inner wall of the T-shaped limit seat 17, which is convenient for quickly adjusting the limit position according to the punching and blanking requirements.

[0031] When blanking, the hydraulic cylinder 6 is started forward to drive the rectangular block 9 to move downward. The rectangular block 9 drives the punching cutter head 5 to move downward through the rectangular rod 12. When the rectangular block 9 moves downward, it also drives the inverted U-shaped pressing seat 7 to move downward synchronously through two springs 11. The inverted U-shaped pressing seat 7 drives the two sliding sleeves 14 to slide downward on the corresponding T-shaped guide rods 15 respectively. At the same time, the inverted U-shaped pressing seat 7 drives the two arc-shaped anti-slip rubber sheets 16 to gradually press down on the building steel bars and be blocked and restricted by them. At this time, the continuously downward-moving rectangular block 9 drives the two vertical guide rods 10 and the rectangular rod 12 to move downward alone and compress the spring 11. The compressed spring 11 is used to drive the inverted U-shaped pressing seat 7 to tightly press and fix the building steel bars. The rectangular rod 12 that continues to move downward alone drives the punching cutter head 5 to move downward to cut the building steel bars for blanking work. By borrowing the downward movement force of the punching cutter head 5 to automatically elastically tighten and press the steel bars integrally, the effect of single-drive integral automatic fixing and blanking of building steel bars is achieved, without the need to separately set and operate the driving equipment for fixing, improving the use convenience and energy saving;

[0032] After blanking is completed, the hydraulic cylinder 6 is started in reverse to drive the rectangular block 9 to move upward. The rectangular block 9 releases the compression force on the spring 11 upward. At the same time, the rectangular block 9 drives the punching cutter head 5 to move upward and be received into the inverted U-shaped pressing seat 7 through the rectangular rod 12. After the compression force is released, the continuously upward-moving rectangular block 9 squeezes the stop block 13 to move upward. The stop block 13 drives the inverted U-shaped pressing seat 7 to move upward and reset, releasing the pressing state, so that it is convenient to automatically receive and hide the punching cutter head 5 for protection when lifting after use, avoiding the phenomenon of accidentally touching the punching cutter head 5 when taking and placing the building steel bars, and improving the use safety.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
