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 seat for prolonging the service life of a trimming die bore convex-narrow structure. The die seat comprises three main parts including a fixing concave die dovetail (1), a support concave die boss (2) and a support boss base plate (3), wherein the fixing concave die dovetail (1) is located at the uppermost part of the middle of the die seat, and comprises a positioning base surface, a left fixing inclined plane and a right fixing inclined plane, the support concave die boss (2) is located at a front upper end below the fixing concave die dovetail (1) in the middle of the die seat and above the support boss base plate (3); the support boss base plate (3) is located at the lowest part of the middle of the die seat. By using the die seat, the service life of the conventional trimming die can be directly prolonged, and the use cost of the conventional trimming die is lowered.

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.
