The positioning mechanism 3 is used to position and fix the left and right sides of the U-shaped steel template 2; the buffer mechanism 4 is arranged in the U-shaped steel template The plate 2 has two ends connected to the inner top surface of the U-shaped steel template 2 and the top surface of the positioning mechanism 3 respectively, and the buffer mechanism 4 is used to reduce the vibration generated during the punching process; the squeezing and pushing mechanism 5 is arranged on the mounting platform 1, and is respectively located on the left and right sides of the U-shaped steel template 2, and the squeezing and pushing mechanism 5 is used to fix the left and right sides of the outside of the U-shaped steel template 2, and drive the U-shaped steel template 2 to move for continuous punching; the punching mechanism 6 is arranged on the mounting platform 1, and is connected to the left and right sides of the mounting platform 1, and its middle part is located above the U-shaped steel template 2, and the punching mechanism 6 is used to punch the U-shaped steel template 2.

[0031] The positioning mechanism 3 includes a force block 21, a double-headed cylinder 22, and a push plate 23. The force block 21 is horizontally arranged on the mounting platform 1 and is located in the U-shaped steel template 2. The front and rear sides of the force block 21 are provided with installation grooves that penetrate left and right. The double-headed cylinder 22 is fixedly arranged in the installation groove, and its two piston rods extend out of the installation groove to the left and right respectively. There are two push plates 23 arranged along the left and right horizontal directions, and the opposite sides of the two push plates 23 are fixedly connected to the two piston rods of the double-headed cylinder 22 respectively. Start the double-headed cylinder 22, so that the two piston rods of the double-headed cylinder 22 extend synchronously, driving the push plate 23 to move to the left and right sides of the inside of the U-shaped steel template 2, thereby positioning and fixing the U-shaped steel template 2. At the same time, it can be applied to U-shaped steel templates 2 of different specifications and widths, thereby improving the scope of application.

[0032] In another embodiment, the positioning mechanism 3 further includes a protective pad 24; two protective pads 24 are provided along the left and right horizontal directions, and the two protective pads 24 are respectively fixedly connected to the opposite sides of the two push plates 23.

Start the squeezing and pushing cylinder 54, drive the top plate 55 to press the left and right sides of the U-shaped steel template 2, and further fix the U-shaped steel template 2, thereby improving the fixing effect of the U-shaped steel template 2 and ensuring the stability of the U-shaped steel template 2 during the punching process. At the same time, the slider 53 slides on the slide rail 52, driving the squeezing cylinder 54 to move, so that the top plate 55 drives the U-shaped steel template 2 to move, thereby switching to another punching position of the U-shaped steel template 2 to achieve continuous punching.

[0035] In another embodiment, the squeezing and pushing mechanism 5 further includes an anti-skid pad 56, which is fixedly arranged on the side opposite to the top plate 55. The anti-skid pad 56 is used to increase the friction between the squeezing and pushing mechanism 5 and the U-shaped steel template 2, thereby improving the fixing effect of the U-shaped steel template 2.

[0036] The punching mechanism 6 includes a hydraulic rod 61, a horizontal plate 62, and a punching head 63; two hydraulic rods 61 are vertically arranged, respectively arranged on the top surface of the mounting platform 1 and located outside the squeezing mechanism 5, and the top ends thereof extend upwardly out of the top surface of the U-shaped steel template 2; the horizontal plates 62 are arranged horizontally from left to right, and the bottom ends thereof are fixedly connected to the tops of the two hydraulic rods 61; the punching head 63 is arranged vertically, and the top ends thereof are fixedly connected to the middle part of the bottom surface of the horizontal plates 62. The hydraulic rod 61 is started to shrink, so that the horizontal plates 62 drive the punching head 63 to move downward, thereby punching holes in the U-shaped steel template 2.

[0037] The pressing plate 42, the force bearing block 21 and the mounting platform 1 are all provided with vertically penetrating through grooves 7; they also include connecting plates 8 and guide plates 9; the connecting plates 8 are horizontally arranged between the two legs 21 of the mounting platform 1; one end of the guide plate 9 is fixedly connected to the connecting plate 8, and the other end is tilted upward and located below the through groove 7. When the punching mechanism 6 punches the U-shaped steel template 2, the waste falls from the through groove 7 to the guide plate 9 and falls along the guide plate 9, which is convenient for collecting the waste.

[0038] The working mode of the present invention is:

[0039] Place the U-shaped steel formwork 2 on the pressure plate 42 of the buffer mechanism 4 with the opening facing downward. The damping telescopic rod 41 and the spring 43 of the buffer mechanism 4 push the U-shaped steel formwork 2 to create a gap between the bottom of the U-shaped steel formwork 2 and the bottom of the mounting platform 1. Start the double-headed cylinder 22 of the positioning mechanism 3, so that the two piston rods of the double-headed cylinder 22 extend synchronously, driving the push plate 23 and the protective pad 24 to move to the left and right sides of the inside of the U-shaped steel formwork 2, so that the protective pad 24 presses the U-shaped steel formwork 2 to position and fix the U-shaped steel formwork 2; start the squeezing and pushing cylinder 54, drive the top plate 55 and the anti-skid pad 56 to move, so that the anti-skid pad 56 presses the left and right sides of the U-shaped steel formwork 2 to further fix the U-shaped steel formwork 2.

[0040] After fixing, the hydraulic rod 61 of the punching mechanism 6 is started, and the hydraulic rod 61 contracts, so that the horizontal plate 62 drives the punching head 63 to move downward, thereby punching the U-shaped steel template 2. The waste material falls from the through groove 7 into the guide plate 9 and falls along the guide plate 9.

[0041] When punching the next position, start the hydraulic rod 61 of the punching mechanism 6, the hydraulic rod 61 is extended, driving the cross plate 62 to rise, so that the punching head 63 leaves the U-shaped steel template 2; start the double-headed cylinder 22 of the positioning mechanism 3, so that the two piston rods of the double-headed cylinder 22 are synchronously contracted, so that the protective pad 24 no longer presses the U-shaped steel template 2; the slider 53 slides on the slide rail 52, driving the pushing cylinder 54 to move, so that the anti-slip pad 56 drives the U-shaped steel template 2 to move, thereby switching to another punching position of the U-shaped steel template 2, and starting the punching mechanism 6 again to continue punching.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
