Embodiment Construction

[0033] Attached below Figure 1-14 Embodiments of the present invention are described.

[0034] The special mold for stamping inner bending parts has a first mold assembly and a second mold assembly. The first mold assembly includes a punch I1, a die I2, a mold upper plate 3, a fixed plate 4, a pad 5, and a mold The lower plate 6 and the ejector 7, the two sides of the lower end of the punch I1 are formed with avoidance grooves 9; the second mold assembly includes the punch II12, the die II13, the handle II14, the mold base 15, and the lower template 16 And the crowbar 17, the lower part of the punch II 12 is formed with a V-shaped transition section 20, the lower part of the V-shaped transition section 20 is formed with a forming straight section 21, and the lower part of one side of the forming straight section 21 is formed with an inclined stamping forming section 22. The lower part of the inclined stamping forming section 22 is formed with a direct pressing forming sectio...

Abstract

The invention discloses a special die for stamping an inward bending part and a stamping method. The special die for stamping the inward bending part is provided with a first die component and a second die component, a bottom round angle of a blank is precisely bent through the first die component, and the second die component bends the blank into the part shape which conforms to size requirements based on keeping the bottom round angle. The special die for stamping the inward bending part has high practical value.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a special die for stamping inner curved parts and a stamping method. Background technique [0002] Most of the existing textbooks, professional design tool materials, and atlas cases introduce the classic U-shape, V-shape, Shape, Huff Shape and other stamping and bending forming process and related die design. while the shape is curved inwards Shaped parts belong to atypical special-shaped structure, the stamping process is relatively poor, it is difficult to formulate the stamping process plan, and it is also difficult to design the stamping die. This part is a special elastic element dedicated to a large aircraft, and the size and structure of the part cannot be changed. According to the traditional stamping process for mold design, The strength of the curved fillet at the bottom of the shape is insufficient, the fillet at the bottom of the part is freely formed,...
