Description

Technical Field

[0001] This utility model relates to the technical field of metal wire processing equipment, and more specifically, to a self-locking device for the shaft core of an I-beam wheel. Background Technology

[0002] Twisting machines are widely used equipment in the production of steel wire rope. In the process of winding and unwinding steel cord, steel wire is released from the I-beam reel, and a drive motor rotates to twist the wire into steel cord. The I-beam reel then collects the twisted steel cord. During production, empty reels need to be frequently replaced with full ones. Generally, the I-beam reel shaft in twisting machines is fixed with a hexagonal nut or a retaining spring, making disassembly inconvenient. Existing technology (CN202543709U) discloses a quick-release I-beam reel mechanism for steel cord twisting machines, including a clamping plate and an I-beam reel shaft. The clamping plate is directly clamped onto the I-beam reel shaft. However, vibrations generated during operation can cause wear between the clamping plate and the I-beam reel shaft.
