TECHNICAL FIELD

[0001] The utility model relates to mould technical field especially relates to a shaping mould of bow-shaped shackle. BACKGROUND

[0002] The bow-shaped shackle is widely used on the ship or mooring platform, and has the technical features of high strength and toughness. The bow-shaped shackle has high performance and size requirements for the inner file part, chain diameter and ball head part, otherwise the assembly of the chain and other accessories will be affected. In daily production, the traditional shaping process of the bow-shaped shackle is to place the inner file mould in the product inner file, then knock the outer side of the shackle ball head through the free forging hammer, so that the shackle shape is attached to the inner file mould, until the shape meets the requirements of the product drawing. This method is feasible for the production of small size bow-shaped shackles, but it is not suitable for the production of large size bow-shaped shackles. Not only the operation is complicated, but also the shape of the chain diameter part and the ball head part cannot be absolutely guaranteed to be consistent with the design drawing. In order to facilitate production, a shaping mould matched with the bow-shaped shackle is specially designed to improve the efficiency and reduce the cost. SUMMARY

[0003] The utility model aims at solving the above technical problem, and provides a shaping mould of bow-shaped shackle.

[0004] In order to realize the above technical purpose and achieve the above technical requirements, the utility model adopts the technical scheme that a shaping mould of bow-shaped shackle, including upper shaping mould, lower shaping mould, the upper shaping mould is connected with the upper anvil of press, the lower shaping mould is connected with the lower anvil of press, the lower shaping mould is same with the upper shaping mould in structure, and is arranged symmetrically, the lower surface of upper shaping mould is provided with upper shaping mould cavity, the upper surface of lower shaping mould is provided with lower shaping mould cavity, the upper shaping mould cavity and lower shaping mould cavity constitute the shaping mould cavity of bow-shaped shackle, and the cavity shape is matched with the target geometric dimension of bow-shaped shackle.

[0005] Preferably, the upper shaping mould cavity includes an omega-shaped cavity arranged in the middle and half flat drum-shaped cavities symmetrically arranged at both ends, and the omega-shaped cavity and the half flat drum-shaped cavities are smoothly connected.

[0006] Preferably, the half flat drum-shaped cavities are middle curved surface structures and both sides are flat structures.

[0007] Compared with the traditional structure, the utility model has the beneficial effects that the structure is simple, the operation is convenient, the shaping of the shackle is completed by using the integral shaping mould, the shaping precision is high, the size of the chain diameter part and the ball head part of the shackle is guaranteed to be consistent with the design drawing, the product quality is guaranteed, the production efficiency is improved, the production cost is reduced, and the production of different specifications of bow-shaped shackles can be applied.
