Terminal Housing Corner Forming Without CNC Milling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing efficiency of terminal device housings is low due to the need for time-consuming numerical control milling machining to reduce the size of rounded corners, which also leaves texture traces on the appearance surface.
Innovation Solution
Implement pressure machining to reduce the radius of rounded corners by allowing plastic deformation at these corners, using structural portions with grooves and extrusion surfaces to minimize the impact on structural integrity and eliminate the need for milling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If numerical control milling machining is used to reduce the size of rounded corners, then the appearance and refinement of the housing is improved, but the manufacturing time is increased and production efficiency is lowered
Solution Approach 1:
The patent applies preliminary action by designing the bending mold with pre-formed rounded corner structures that directly create the desired small-radius rounded corners during the bending process itself, eliminating the need for subsequent numerical control milling operations. The mold includes rounded corner forming sections that shape the housing corners in advance, achieving both appearance quality and manufacturing efficiency.
2Shape
If the rounded corner size is reduced to improve appearance, then the refinement of the housing is improved, but the structural strength may be compromised
Solution Approach 1:
The patent applies parameter changes by optimizing the bending parameters and mold design parameters to achieve small-radius rounded corners while maintaining structural strength. The bending process parameters are carefully controlled to create the desired corner geometry without compromising the overall structural integrity of the housing. The mold design includes specific pressure distribution and forming parameters that ensure both appearance and strength requirements are met.

AI summary
Embodiments of this application relate to the field of terminal device technologies, and provide a housing, a manufacturing method therefor, and a terminal device, which can resolve a problem of high manufacturing costs of the housing of the terminal device in related technologies. The includes a bottom wall and a side wall bent and connected to an edge of the bottom wall, where a part of the side wall away from the bottom wall is bent inward to form an inner bent wall, and a part of the side wall located between the inner bent wall and the bottom wall is a vertical wall; and a first corner formed by the inner bent wall and the vertical wall is provided with a first structural portion formed by pressure machining, so that plastic deformation occurs at a first rounded corner located on an outer side of the first corner, to reduce a radius of the first rounded corner.
