Rotatable Lower Die Structure for Multi-Size Button Badge Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional button badge making machines have a large number of costly components, require high replacement costs due to the need for different die parts for various badge sizes, and face issues with inconsistent press forces for different making steps.
Innovation Solution
A button badge making machine design featuring a support frame with adjustable resilient units and a lower die that can change positions to accommodate different press strokes, allowing for a single lower die to perform both making steps with varying resilient support, reducing component count and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two lower dies are used to provide different press strokes for two making steps, then the press stroke requirements are met, but the number of component parts increases and manufacturing cost rises
Solution Approach 1:
A single lower die is designed to perform both making steps by incorporating a lower peripheral die seat that can rotate between two angular positions. This allows one die to provide two different press strokes: a first longer press stroke for the first making step and a second shorter press stroke for the second making step, eliminating the need for two separate lower dies and reducing component complexity
Solution Approach 2:
The lower peripheral die seat is made rotatable relative to the lower support member about a rotating axis, allowing dynamic repositioning between the first and second angular positions. This dynamic adjustment enables the same die structure to adapt to different press stroke requirements for different making steps, resolving the contradiction between maintaining precision and reducing complexity
2Adaptability or versatility
If all component parts of upper and lower dies are replaced for making different sizes of button badges, then various badge sizes can be produced, but replacement cost and inconvenience increase
Solution Approach 1:
The lower die structure with rotatable peripheral die seat is designed to accommodate different badge sizes through rotation and resilient movement, reducing the frequency of complete die replacements. The resilient units allow the same die to adapt to different press stroke requirements for various badge types
Solution Approach 2:
The rotatable and resiliently movable lower peripheral die seat provides dynamic adaptability for different badge sizes and press stroke requirements, allowing operators to adjust the die configuration rather than replacing entire die sets, thereby improving ease of operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine achieves efficient production of various button badge sizes with reduced component complexity and lower replacement costs, while maintaining precise control over press forces for each making step.
Implementation Method 1
a first resilient unit and a second resilient unit which extend in the upright direction and project upwardly from the lower support member... The first and second support surfaces are resiliently movable downwardly relative to the lower support member
Implementation Method 2
press the upper body and the pattern layer together and transfer the upper body and the pattern layer to the upper die against a first counteracting force generated as a result of a first downward resilient movement of the lower peripheral die seat and the first support surface

AI summary
A button badge making machine includes a support frame and a lower die. The support frame includes a lower support member and first and second resilient units projecting upwardly from the lower support member and respectively having upwardly facing first and second support surfaces. The lower die includes a lower center die seat disposed on the lower support member, and a lower peripheral die seat surrounding and movable relative to the lower center die seat. The lower peripheral die seat is turnable about a rotating axis relative to the lower support member between first and second angular positions to be supported by the first and second support surfaces, respectively, with different resilient supports.
