Embodiment Construction

[0025] A forming process of a cup body part, comprising the following steps:

[0026] (1) Cutting

[0027] CNC machine tools are used for milling and blanking, and the blanking size is Ф85;

[0028] (2) Hemisphere deep drawing with flange

[0029] 100T punching machine is used for the first deep drawing, and the part is processed into a hemispherical shape with a flange edge;

[0030] (3) Intermediate annealing

[0031] Eliminate internal stress during part forming;

[0032] (4) Transition deep drawing

[0033] 100T punch press is used for the second deep drawing;

[0034] (5) Final deep drawing

[0035] Use 100T punch press for the third deep drawing;

[0036] (6) Die-cut trimming

[0037] Trimming is carried out with a trimming die and a rubber bladder hydroforming machine;

[0038] (7) Hole making and shape correction

[0039] Hole making and shape correction are carried out using molds.

Abstract

The invention belongs to metal plate forming field, and in particular relates to a forming technology for cup body parts. The existing cup body parts are formed by the spinning technology, the surface quality of the formed parts is poor, the part material thickness change is uneven, the surface of the formed part is polished, the production efficiency is low, qualified part delivery cannot be ensured and the rejection rate is relatively high. A novel forming technology for cup body parts is provided, the parts are formed by deep drawing for many times, the surface quality and uneven thickness phenomenon of the formed parts can be effectively improved, the production efficiency is improved, the processing period of parts is shortened and the parts are ensured for good quality for delivery.
