Embodiment Construction

[0021] A kind of die holder (such as Figure 3a and Figure 3b Shown), including three main components of fixed die dovetail 1, support die boss 2 and support boss bottom plate 3.

[0022] The fixed die dovetail 1 is located at the uppermost part in the middle of the mold base (including the positioning bottom surface and one fixed slope on the left and right sides), the supporting die boss 2 is located below the fixed die dovetail 1 in the middle of the mold base, and the support boss bottom plate 3 above the front upper end, the support boss bottom plate 3 is located below the support die boss 2 and at the bottom of the middle of the mold base, the above three main components are integrated structure (compact structure and sufficient strength); the heat treatment hardness of the mold base It is 41~47HRC.

[0023] The length x width x depth x dovetail slope of the fixed die dovetail 1 is 200mm x 200mm x (90-60)mm x 10°, which is the same as Figure 2a and Figure 2b The l...

Abstract

The invention relates to a die base for improving the service life of the convex and narrow structure in the inner hole of the trimming die. The die base includes a fixed die dovetail (1), a support die boss (2) and a support boss bottom plate (3). The main components; the fixed die dovetail (1) is located at the uppermost part in the middle of the mold base, including the positioning bottom surface and one fixed slope on the left and right, and the supporting die boss (2) is located in the middle of the die base. The fixed die dovetail ( Below 1), the front upper end above the support boss bottom plate (3), the support boss bottom plate (3) is located at the bottom in the middle of the mold base. By using the mold base of the invention, the service life of the existing trimming die can be directly improved and the use cost of the existing trimming die can be reduced.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a die base for improving the service life of the convex and narrow inner hole structure of a trimming die. Background technique [0002] When the inner hole of the existing trimming die has a local convex and narrow structure with low service strength, the local convex and narrow structure of the inner hole is always in a suspended state and is subjected to a large bending moment when the edge is trimmed, and it is very easy to break in the inner hole. The root of the local convex and narrow structure of the hole is broken; once the local convex and narrow structure is broken, the existing trimming die will be scrapped as a whole (it will be easier to break after it is broken and repaired by welding), and the service life is extremely low, so , the service life of the local convex and narrow structure determines the overall service life of the existing trimming die.
