Spring Forming Tool Rotation and Retraction Without Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spring forming machines lack flexibility in tool rotation, often resulting in jamming and difficulty in retracting tools, leading to processing blind angles, low yield, and increased need for secondary processing and reworks.
Innovation Solution
The spring forming machine employs an inner circle core rotation transmission mechanism and an outer circle tool rotation transmission mechanism, allowing independent 360-degree rotation of discs, and incorporates a swing component and tool component for lever-like movements to facilitate smooth tool retraction, enabling flexible processing without blind angles and reducing the need for reworks.

Engineering Contradiction Analysis
1Device complexity
If the tool rotates synchronously together with the axle core (unitary transmission), then the structure is simple, but the tool lacks flexibility and is liable to being jammed
Solution Approach 1:
The transmission system is segmented into two independent rotation systems: an inner circle core rotation transmission mechanism for the axle core, and an outer circle tool rotation transmission mechanism for the tool. This segmentation allows each component to rotate independently, eliminating the jamming issue while maintaining structural manageability through modular design.
Solution Approach 2:
The system transitions from a static synchronous rotation to a dynamic independent rotation system. The tool can now rotate independently from the axle core, allowing flexible adjustment of rotation angles and speeds to adapt to different spring forming requirements, thereby improving versatility without excessive complexity.
2Adaptability or versatility
If the tool rotates independently from the axle core, then processing flexibility increases, but the device complexity increases
Solution Approach 1:
The inner circle core rotation transmission mechanism is nested within the outer circle tool rotation transmission mechanism. The core rotation bridge gear is positioned at the center, with the rotary beak seat mechanism and tool rotation gears arranged concentrically around it. This nested arrangement allows independent rotation capabilities while maintaining a compact and organized structure.
Solution Approach 2:
The core rotation bridge gear acts as an intermediary component that connects the inner circle core rotation to the outer circle tool rotation system. It mediates the transmission between the two independent rotation systems, enabling flexible tool rotation while maintaining structural coherence and managing complexity through a clear transmission path.
3Device complexity
If conventional tool retraction mechanism is used, then the structure is simple, but tool retraction fails or jams
Solution Approach 1:
The tool retraction mechanism uses dynamic lever-like turning and flipping movements instead of simple linear retraction. The swing component performs oscillating motion to drive the tool component upward for retraction, providing reliable tool withdrawal while maintaining moderate structural complexity through the use of swing and lever mechanisms.
