Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bending die technologies have complex configurations that complicate operation and lead to extended formation cycles and burr generation when forming three-dimensionally bent rod-shaped bodies, as they require intricate movements and retraction of components to avoid interference during clamping.
Innovation Solution
A bending die with a pair of forming dies clamped in the Z direction, featuring semicircular rod-shaped body-forming recess portions and V-shaped comb-like guide portions that allow for easy alignment and bending of rod-shaped bodies in a three-dimensional XYZ direction without interference, enabling quick and reliable bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If opening/closing split dies with upright wall and core are used to bend parison, then three-dimensional bent shape can be formed, but device complexity increases and operation becomes difficult
Solution Approach 1:
The die is divided into two separate forming dies with distinct functions: one die has a rod-shaped body-forming recess portion for defining the final shape, while the other die has a guide portion for directing the rod-shaped body into position. This segmentation allows each component to be simpler while collectively achieving three-dimensional bending capability.
Solution Approach 2:
The guide portion is designed with a V-shape that spreads outward from both sides of the rod-shaped body-forming recess portion, creating a three-dimensional guiding path. The comb-like structure extends in multiple directions to guide the rod-shaped body along a three-dimensional trajectory during forming.
2Ease of operation
If upright wall and core are retracted before closing dies, then interference during clamping is avoided, but formation cycle lengthens
Solution Approach 1:
The guide portion is designed to automatically guide the rod-shaped body into the correct position as the dies close, eliminating the need for preliminary retraction actions. The V-shaped comb-like structure预先 positions the rod-shaped body along the forming path, allowing continuous operation without interruption.
3Ease of operation
If upright wall and core are retracted before closing dies, then interference is avoided, but burr generation occurs due to parison position change
Solution Approach 1:
The guide portion acts as an intermediary element between the rod-shaped body and the forming recess portion. It maintains continuous contact with the rod-shaped body during die closing, ensuring accurate positioning throughout the process and preventing burr formation at the interface.
4Device complexity
If simple die configuration is used without core, then device complexity reduces, but parison loading control becomes difficult
Solution Approach 1:
The guide portion is designed to automatically perform the function of loading and positioning the rod-shaped body without requiring a separate core component. The V-shaped comb-like structure self-adjusts to guide the rod-shaped body into the correct position as the dies close, achieving both simplicity and operational ease.
