Triaxial Spring Tool Layout for Multi-Type Spring Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring-making machines are limited in their ability to produce multiple types of springs due to fixed spatial arrangements of processing tools, making it difficult to manage different spring types and increasing complexity, especially when mixed types need to be processed.
Innovation Solution
A triaxial spring-making machine with a working tool device featuring movable members that allow tools to be mounted on multiple surfaces and move synchronously in opposite directions, enabling three-axis operations and easy switching between tools without requiring tool repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If processing tools are arranged in a fixed radial manner on the base, then the machine can produce one type of spring with a fixed program, but the machine cannot easily switch to produce different types of springs without redesigning the tool arrangement
Solution Approach 1:
The patent transforms the fixed radial arrangement of processing tools into a dynamic modular system. Processing tools are mounted on movable carriers that can be repositioned along the wire axis and rotated around the wire guide member, enabling the machine to adapt to different spring types while maintaining efficient production for each specific configuration.
Solution Approach 2:
The patent divides the processing tool system into modular segments. Each processing tool is mounted on an independent carrier that can be individually positioned and configured. This segmentation allows tools to be rearranged for different spring types without affecting the entire tool system, resolving the contradiction between fixed efficient production and flexible adaptability.
2Adaptability or versatility
If the number of processing tools is increased to handle mixed types of springs, then the machine can process more spring varieties, but the spatial arrangement becomes increasingly complex and tools interfere with each other's movement
Solution Approach 1:
The patent introduces additional spatial dimensions for tool arrangement. Instead of confining tools to a two-dimensional radial plane, tools are positioned in three-dimensional space with adjustable positions along the wire axis, radial distance from the wire guide, and angular orientation. This dimensional expansion allows multiple tools to coexist without interference while maintaining versatility for processing various spring types.
3Device complexity
If processing tools are mounted on a fixed base with approximate radial arrangement, then the structure is simple, but the tools cannot move in a movable working space without interfering with one another
Solution Approach 1:
The patent creates a universal base structure that supports multiple functions. The base maintains its simple radial mounting configuration but incorporates movable carriers with adjustable positioning mechanisms. This allows the same base structure to serve both as a stable mounting platform and as a system that enables tool repositioning for different spring types, eliminating the need for redesign when changing production requirements.

AI summary
A method for making spring includes providing a wire at a working plane by a wire feeding machine; shaping the wire by a first working tool based on a first structure for the spring; and shaping the wire by a second working tool based on a second structure for the spring. In particular, the first working tool and the second working tool are configured to be movable in a reversed-reciprocation way along a direction perpendicular to the working plane.
