Abstract

The invention discloses a drawing die structure which comprises a male die seat, a binder ring and a male die. The male die seat is provided with an installation table, and the male die is installed on the side, away from the male die seat, of the installation table; the male die is installed on the male die seat through installation keys and bolts, and the four installation keys are located at the upper edges of the four side faces of the installation table correspondingly; the projection of the installation table on the male die seat is located in the projection of the male die on the male die seat; the side faces of the installation tables are provided with first guide sliding faces, the projections of the first guide sliding faces on the male die seat are located in the projection of the male die on the male die seat; and the binder ring is installed on the male die seat through safe stroke bolts, and the inner wall of the binder ring is provided with second guide sliding faces matched with the first guide sliding faces. The drawing die structure is small in size while meeting the same rigidity condition.

Description

technical field [0001] The invention relates to the technical field of drawing dies, in particular to a drawing die structure. Background technique [0002] In the design of large-scale stamping parts, especially outer cover parts, in order to ensure the formability of stamping parts and the structural strength of the mold, the size of the mold is generally relatively large. At present, the length of most machine tool tables is 4.5 meters and the width is 2.5 meters. Some large stamping parts have a mold size larger than this size, and part of the mold structure will be exposed outside the machine tool table, which not only affects the formability of stamping parts, but also has certain safety hazards . Although the tabletop can be increased by repurchasing or transforming the machine tool, this method is costly and economically poor. [0003] In prior art, please refer to Figure 1 to Figure 3 , figure 1 It is a structural schematic diagram of a drawing die disclosed in...
