AI Technical Summary
Technical Problem
In existing air-conditioning fin molds, the connection strength between the strike block and the guide rod is poor, which can easily lead to the breakage of the guide rod or pin, resulting in the failure of the rod punch function.
Method used
The interference fit between the guide rod and the strike block is used, and the strike block is locked on the guide rod through threaded holes and screw plugs to ensure uniform transmission of impulse pressure and avoid stress concentration.
Benefits of technology
It effectively avoids the fracture phenomenon between the guide rod and the strike block, and improves the service life and functionality of the rod structure.

Abstract
The utility model belongs to the technical field of fin dies, and discloses an improved structure of a beating rod of a transverse cutting sub-die, which comprises a guide rod and a beating block, the beating block is provided with a transverse through hole and a threaded hole vertically communicated with the through hole, the guide rod is arranged in the through hole in a penetrating manner and is in interference fit with the beating block, and a screw plug is assembled in the threaded hole. The end of the screw plug abuts against the surface of the guide rod. According to the improved structure of the beating rod of the transverse cutting sub-mold, the guide rod is in interference fit with the beating block, and the position of the beating block on the guide rod is locked through the screw plug, so that punching force borne by the beating block is uniformly transmitted to the guide rod, stress concentration is avoided, the breakage phenomenon is effectively avoided, and the service life of the beating rod structure is prolonged; and the functionality of the knock-out rod structure is ensured.
