[0027] Specifically, the electric push rod 16 is started to press the main traction frame 10 downward, and as the main traction frame 10 moves downward, the linkage push rod 7 moves downward, and at the same time, the angle of the linkage push rod 7 changes with the pressure, and the linkage push rod 7 generates an outward thrust on the side traction frame 14, when the drill bits of the middle puncher 13 and the side puncher 15 pass through the holes inside the pressing arc plate 11, thereby drilling holes in the leaf spring, and drilling is performed at multiple points at the same time. By drilling holes at multiple points at the same time, the efficiency of drilling holes in the leaf spring is further accelerated.

[0029] Specifically, the steel leaf spring to be punched is placed inside the spring support frame 8, and the arc surface of the steel leaf spring will fall into the middle of the spring support frame 8. The cylinder 5 is started to push the push rod 4 downward, thereby pressing the pressing frame 6 downward, and the pressing frame 6 exerts downward pressure on the side support frame 9 and the pressing frame 12, thereby moving the pressing arc plate 11 downward inside the spring support frame 8. The pressing arc plate 11 applies downward pressure on the steel leaf spring, and the spring will expand outward with the pressure, thereby fitting the steel leaf spring inside the spring support frame 8 for stabilization. The debris generated by the punching will fall into the collection space frame 17 and fall into the collection box 18 for collection with the vibration, so that the steel leaf spring can be stabilized while expanding, avoiding vibration of the steel leaf spring due to its own elasticity during the punching process, thereby improving the quality of the punching.

[0031] Specifically, when the arc pressing plate 11 is pressed downward, the limit moving rod 3 moves inside the mounting frame 2 accordingly, and limits the downward pressing of the arc pressing plate 11, thereby ensuring the stability of the downward pressing.

[0032] Working principle: Place the leaf spring to be punched inside the spring support frame 8, the arc surface of the leaf spring will fall in the middle of the spring support frame 8, start the cylinder 5 to push the push rod 4 downward, thereby pressing the pressing frame 6 downward, and the pressing frame 6 exerts downward pressure on the side support frame 9 and the pressing frame 12, thereby moving the pressing arc plate 11 downward inside the spring support frame 8, and the pressing arc plate 11 applies downward pressure to the leaf spring, and the spring will expand outward with the pressure, thereby fitting the leaf spring inside the spring support frame 8, thereby stabilizing it. When the leaf spring is completed When pressed, the electric push rod 16 is started to press the main traction frame 10 downward, and as the main traction frame 10 moves downward, the linkage push rod 7 moves downward, and at the same time, the linkage push rod 7 changes its angle as the pressure produces, and the linkage push rod 7 produces an outward thrust on the side traction frame 14, when the drill bits of the middle puncher 13 and the side puncher 15 pass through the holes inside the pressing arc plate 11, thereby drilling holes in the leaf spring, and punching is performed at multiple points at the same time, and the debris generated by the punching will fall into the collection space frame 17, and fall into the collection box 18 for collection as the vibration occurs.
