[0037] Please refer to Figure 1 、 Figure 4 And Figure 5 Two clamping mechanisms 4 are symmetrically arranged on the punching member 6, for pre-limiting the purlin 7 to be punched before punching. The clamping mechanism 4 includes a connecting seat 41 fixedly connected to the end of the punching seat 66 by bolts, an outer cylinder 43 and an inner rod 44 are arranged on one side of the connecting seat 41, the inner rod 44 extends into the sliding cavity 42 and is slidably connected thereto, the outer cylinder 43 is fixedly connected with the connecting seat 41, the sliding cavity 42 is formed in the inner side of the outer cylinder 43, one end of the inner rod 44 located in the inner side of the outer cylinder 43 is fixedly connected with a movable disc 46, and the movable disc 46 is in sliding fit with the sliding cavity 42. A rubber sleeve 45 is sleeved on the end of the inner rod 44 away from the outer cylinder 43, and a supporting spring 47 is fixedly connected between the movable disc 46 and the sliding cavity 42. Before the two punching members 6 on the two right-angle seats 34 punch, the rubber sleeve 45 on the inner rod 44 is in contact with the purlin 7 to be punched in advance, and as the two right-angle seats 34 approach each other, the inner rod 44 shrinks into the outer cylinder 43, and the supporting spring 47 is compressed, thereby limiting the purlin 7 to be punched on the U-shaped sleeve frame 81 or the convex sleeve frame 91 by the rubber sleeve 45.

[0038] Please refer to Figure 1A collecting assembly 5 is arranged at the bottom of the base 11 to collect the debris generated during the punching process.

The waste generated during the punching process falls into the collecting frame 51 through the leakage grooves 55 for collection. The right-angle frames 54 and the eaves plates 53 facilitate the installation and removal of the collecting frame 51.

[0039] Working principle and use process: during work, the appropriate punching limiting die is selected and installed on the top of the base 11 to limit the purlin 7 to be punched. When the three sides of the same purlin 7 to be punched need to be punched simultaneously, the purlin 7 to be punched is sleeved on the outer side of the U-shaped sleeve frame 81. When three purlins 7 to be punched need to be punched simultaneously, the three purlins 7 to be punched are respectively sleeved on the three protruding ends of the convex sleeve frame 91. During the punching work, the electric hydraulic device 2 is started to drive the H-shaped lifting plate 13 to move up and down. During the downward movement of the H-shaped lifting plate 13, the T-shaped movable frame 31 is driven to move downward. During the downward movement of the T-shaped movable frame 31, the transmission inclined chute 32 can press the transmission inclined support 39 downward. Under the cooperation of the T-shaped sliding block 35 and the T-shaped sliding groove 111, the transmission inclined support 39 can drive the right-angle seat 34 to stably slide away from the fixed seat 38, so that the guide rod 37 slides in the fixed seat 38, the return spring 36 is stretched, and the two right-angle seats 34 approach each other, so that the punching part 6 installed on the lifting seat 14 can punch in the up-down direction, and the two punching parts 6 on the two right-angle seats 34 can punch in the left-right direction, which greatly improves the work efficiency. Before the two punching parts 6 on the two right-angle seats 34 punch, the rubber sleeve 45 on the inner rod 44 is in contact with the purlin 7 to be punched. As the two right-angle seats 34 approach each other, the inner rod 44 is retracted into the outer cylinder 43, the supporting spring 47 is compressed, and the purlin 7 to be punched is pressed and limited on the U-shaped sleeve frame 81 or the convex sleeve frame 91 by the rubber sleeve 45, which improves the stability during punching. The waste generated during the punching process falls into the collecting frame 51 through the leakage grooves 55 for collection. Under the cooperation of the right-angle frames 54 and the eaves plates 53, the collecting frame 51 is convenient to install and remove. After the punching is completed, the transmission inclined chute 32 removes the downward pressing effect on the transmission inclined support 39 during the upward movement of the T-shaped movable frame 31. At this time, the right-angle seat 34 is automatically moved and reset by the good elastic property of the return spring 36.

[0040] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
