Stabilizer Through-Hole Forging With Recessed Perforation Ends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The durability of perforating members used to form through holes in stabilizers is compromised due to wear from applied loads during perforation, limiting the number of uses.
Innovation Solution
A method involving forging processing to create a recess at the through hole formation position, followed by heating, perforation, and burr removal to enhance the durability of the perforating member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a through hole is formed by perforating the end of the stabilizer with a perforating member, then the through hole is successfully formed, but the perforating member is worn by the load applied from the base material, reducing its durability
Solution Approach 1:
A recess is formed at the through hole formation position in the base material before the perforation process. This preliminary action creates a cavity that reduces the material thickness at the perforation point, thereby reducing the load on the perforating member during the actual through hole formation and improving its durability.
Solution Approach 2:
The base material is modified locally at the through hole formation position by creating a recess. This local modification reduces the material density and thickness only at the specific location where the through hole will be formed, without affecting the overall structure of the base material. The recessed area requires less force to penetrate, protecting the perforating member from excessive wear.
2Reliability
If the end of the base material is flattened to form a recess, then the recess is successfully formed to reduce perforation load, but additional processing steps are required
Solution Approach 1:
The recess formation process is merged with the existing flattening operation of the stabilizer end. By integrating the recess creation into the flattening step, the patent avoids adding a separate processing step while still achieving the load-reducing recess structure. The flattening tool is configured to simultaneously flatten the end surface and create the recessed area.

AI summary
A method of manufacturing a stabilizer having a through hole at each of both ends by performing forging processing on a base material includes: a recess forming step of forming a recess at a through hole formation position corresponding to the through hole of the stabilizer at an end of the base material; and a through hole forming step of forming a through hole by performing perforation at the through hole formation position including the recess.
