Benefits of technology

The inventive dies used during this process are designed specifically for use on an airplane's leading edge section (LEP). These dies have three parts - one part called the turning tool or bolt-holder plate, another two made up by welded metal plates, and finally some other components like springs. By doing these processes, it becomes possible to create precision accurate and uniformly shaped structures without excess material being left behind inside them due to poor fill quality caused by overlapping layers between different materials when forming certain ferrous metals such as aluminum alloys.

Problems solved by technology

This patented problem addressed by this patents relates to improving the design of dies used for making metal parts that are critical components of airplanes' wingspan due to their weight and complexity. These engines require strong connections between different structures like those found on other portions of the wing (the tail). Existing methods have limitations such as lacked precision when creating complicated shapes needed for these types of metals.

Embodiment Construction

[0026] In view of this, the core of the present invention is to provide a die forging process for the main lifting joint of the aircraft, which can effectively avoid the phenomenon of insufficient filling, folding, and flow-through at the high ribs of the main starting joint, thereby obtaining high dimensional accuracy and uniform deformation structure die forgings.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The die forging process method for the main lifting joint of the aircraft disclosed in the embodiment of the present invention includes: 1) heating the ingot blank 1, and adopting the free forging method to open the rotary blank 1 to form the free forging blank 2; 2) forming the free forging blank 2; The blank 2 is processed into a preform 3 of a predetermined shap

Abstract

The invention discloses a die forging process method of a main starting connector of an airplane. The die forging process method includes the steps that 1), a cast ingot blank is heated, and the rotary blank is cogged with a free forging method to form a free forging blank; 2), the free forging blank is machined into a prefabricated blank with a preset shape; 3), the prefabricated blank is machined into a pre-pressed part with a pre-formed high line; and 4), a main starting joint die forging finally-pressed part is formed by the pre-pressed part through a final pressing procedure. By means ofthe die forging process method of the main starting connector of the airplane, the phenomena that insufficient filling, folding, cross flowing and the like exist at the position of the high line of the main starting connector can be effectively avoided, and therefore a die forging with high dimensional precision and a uniform deformation structure is obtained.
