[0014] The present invention will be further described below.
[0015] See attached document Figures 1-4 A transmission structure for a shaping arm of an anchor chain looper includes a shaping cylinder 1 and a shaping arm 5. A piston rod 8 is provided inside the shaping cylinder 1. A concave pad 2 and a convex nut 3 are provided at the front end of the piston rod 8. The concave pad 2 and the convex nut 3 are hinged together. A concave top plate 4 is provided on the inner end face of the shaping arm 5. The ball end of the piston rod 8 is connected to the concave surface of the concave top plate 4 to ensure a tight connection during the forward and backward movement of the shaping arm 5. A displacement sensor 6 is connected to the top of the shaping arm 5 via a connecting rod.
[0016] In this preferred embodiment, the front end of the shaping arm 5 is provided with a groove 51, and the concave pad 2, the convex nut 3, and the concave top plate 4 are all disposed in the groove 51.
[0017] In this preferred embodiment, the concave surface of the concave pad 2 engages with the convex surface of the convex round nut 3.
[0018] In this preferred embodiment, the displacement sensor 6 is horizontally positioned.
[0019] In practice, by setting a concave pad 2, a convex nut 3, and a concave top plate 4, the forming arm 5 and the forming cylinder 1 are tightly and reliably connected, possessing high degrees of freedom and capable of transmitting heavy loads. A displacement sensor 6 is connected to the forming arm 5. When the forming arm 5 moves, the displacement sensor 6 sends a signal to the PLC. The PLC controls the sensitive opening and closing of the electro-hydraulic servo valve, thereby precisely controlling the displacement of the forming cylinder 1. The forming arm 6 bends the heated bar material, meeting the precise positioning dimensions required for the production of anchor chains of different specifications, achieving a reliable forming effect.
