Batch Manufacturing Bracelet Links via Profile Bar Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for manufacturing bracelet links are inefficient and costly due to their piece-by-piece nature, resulting in low production rates and high costs.
Innovation Solution
A method for batch manufacturing bracelet links involves machining a profile bar in a single piece, cutting it into rings with multiple blanks, and then separating and shaping the links, allowing for batch machining and reduced costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If piece-by-piece machining techniques are used for bracelet links, then manufacturing precision can be maintained, but productivity is low and cost price is high
Solution Approach 1:
Multiple bracelet link blanks are merged into a single profile bar structure, allowing simultaneous machining of multiple links. The profile bar contains multiple blanks arranged in batches, and machining operations are performed on the entire batch at once, transforming the piece-by-piece process into a batch process that increases productivity while maintaining precision through consistent machining parameters.
Solution Approach 2:
The profile bar is prepared in advance with multiple link blanks already positioned and delimited within it before machining begins. This preliminary arrangement of blanks in a structured batch configuration allows the machining process to operate on pre-organized groups rather than individual pieces, improving manufacturing efficiency and reducing setup time for each link.
2Productivity
If links are machined separately one by one, then each link can be precisely finished, but production time increases and costs rise
Solution Approach 1:
Multiple link machining operations are combined into a single machining cycle by arranging blanks in batches within the profile bar. The machining tool processes all blanks simultaneously or in sequence within the same setup, eliminating repeated positioning and setup times between individual links, thus dramatically reducing total manufacturing time while maintaining quality standards.
3Ease of manufacture
If traditional embossing or die stamping is used to make blanks, then link formation is achieved, but subsequent machining must be done piece-by-piece increasing cost
Solution Approach 1:
Link blanks are preliminarily formed within the profile bar structure during the extrusion process, with slots delimiting individual blanks before machining begins. This preliminary formation in a batch configuration eliminates the need for separate embossing or die stamping operations on each individual link, allowing subsequent machining to be performed on batches rather than pieces, thereby reducing cost and improving productivity simultaneously.

AI summary
1. Method of batch manufacturing bracelet links, characterized in that the method includes the steps of:a) taking a profile bar made of a material in which the link blanks are delimited in relation to each other transversely by slots extending in a general direction of extrusion of the profile bar;b) machining a first blank, if necessary, in the profile bar, while it is still in a single piece,c) cutting the profile bar over a determined length defining the width of the link blanks so as to obtain a ring having the link blanks at the periphery thereof;d) shaping the link blanks into the final form by a final rough machining operation;e) thinning the surface of the ring forming the connection between the link blanks until the links are separated from each other.
