Die forging of the structure of the craft die forging is mainly by forging die cavity to shape the blank, the shape of the forging is more complex. However, in order to reduce the cost of die forging and simplify the die forging process, the design of die forging parts should conform to the following principles according to the characteristics of die forging and process requirements, so as to facilitate the production of die forging and reduce the cost.

(1) The die forging parts must have a reasonable parting surface, so as to ensure that the die forging parts are easy to take out from the forging die, and conducive to metal filling, reducing the remaining pieces and dressings, making the forging die easy to manufacture.

(2) The non-machined surface perpendicular to the parting surface shall be designed with a die forging slope to facilitate the removal of the forgings from the die bore. The intersections of the non-machined surfaces should be rounded to facilitate metal flow filling in the die cavity and to prevent stress concentration.

(3) The setting of too dense reinforcement or too large aspect ratio should be avoided in order to facilitate the metal filling of the mold cavity.

(4) In order to reduce deformation resistance, make metal easy to fill the mold cavity and reduce the process, the appearance of the parts to be simple, straight and symmetrical, try to avoid the difference between the sections of the parts too large, the web is too thin (, or with thin wall, high reinforcement, convex structure.

(5) under the condition of the parts of structure allows, the design should avoid deep hole or porous structure, facilitate molding and reduce the residual block, as shown in figure 5-51 four Φ 20 mm hole cannot of forging, can only use mechanical processing forming.

(6) The combined structure of forging - welding, forging - thread connection, etc. should be adopted for the complex parts to simplify the die and reduce the spare parts and simplify the die forging process

(7) Due to the high dimensional precision and low surface roughness value of the die forging parts, only the surface matched with other parts needs to be machined, and other surfaces should be designed as non-machined surfaces.
