Connecting shackle and manufacturing equipment and manufacturing method thereof

Abstract

The invention discloses a connecting shackle and manufacturing equipment and a manufacturing method thereof. The connecting shackle is formed by forging and pressing a sheet and is riveted by a rivet.When the connecting shackle is buckled, a pressure arm of an inner core needs not to be pressed and a buckling hole of a shackle plate or a round ring of a shackle section is pressed directly, so that the connecting shackle can be buckled and is convenient to use. Industrial automatic production can be achieved and the connecting shackle is light in weight. The manufacturing equipment comprises arack. A plurality of stations are arranged on the rack. Corresponding functional devices are correspondingly arranged in the stations. Each functional device comprises an inner core shearing and forging and pressing device, a shell shearing and forging and pressing device, a rivet forming device, a rivet insertion device, a rivet riveting device, a spring forming device, a spring guiding device,an inner core close-up device and a product detection device. The connecting shackle is high in degree of automation and convenient and efficient to use. By adopting a reasonable manufacturing method,the prior art is optimized, the weight of the equipment is reduced and the connecting shackle is convenient to use and is more humanized.

Description

technical field [0001] The invention relates to the technical field of buckles, in particular to a buckle and its manufacturing equipment and manufacturing method. The design and manufacturing method of the automatic chain buckle of the present invention is mainly used to replace the traditional ring spring buckle used in general lighter chains, and optimize the chain buckle specification of the traditional lobster clasp mode, so that it can be used for thinner diameter and The current mainstream products on the chain with lighter weight include the manufacturing material technology of the chain buckle, especially a reasonable mechanical design mode, increased structural strength and convenient buckle insertion mode and manufacturing method, so that the product of the present invention can be used in The lightest weight among similar or similar models. Background technique [0002] In the jewelry industry, there are two types of precious metal chain clasps. One is ring spri...

AI Technical Summary

Problems solved by technology

[0003] In the existing process, there are many production procedures for the ring-shaped spring buckle, the workpiece is small, the precision of the equipment is very high, and it is not easy to produce at high speed and stably

Due to the design and production process of the lobster clasp, it is impossible to manufacture small and light-weight clasps. In theory, it is impossible to achieve fully automatic production, because the semi-finished products need to be polished after welding, and the assembly line cannot be connected to this process. Otherwise, each process will be affected. And the requirements of the workpiece and the precision requirements are very high, and it is still not easy to produce at high speed and stably

However, the casting model has problems such as the weight cannot be reduced, and the labor cost is high and the process is complicated.
