Floating Block Hub Mold for Heat-Treatment Deformation Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hub products experience significant deformation during heat treatment, leading to increased material consumption, high costs, and low production efficiency when traditional mechanical cutting methods are used to achieve the required size.
Innovation Solution
A hub shaping mold featuring a floating block with inner and outer support members having staggered bulges, which are driven by mechanisms to shape the hub's inner and outer walls, allowing for precise contouring and reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical cutting mode is used to eliminate deformation, then required size can be obtained, but material consumption increases greatly
Solution Approach 1:
The mold performs preliminary shaping action during the heat treatment process itself, pre-forming the hub to close to final dimensions before any cutting operations. This preliminary action by the mold reduces or eliminates the need for subsequent material removal, directly addressing the contradiction between achieving precise size and minimizing material consumption
2Manufacturing precision
If mechanical cutting mode is used to eliminate deformation, then required size can be obtained, but production efficiency decreases
Solution Approach 1:
The mold performs preliminary shaping during heat treatment, combining two operations (heat treatment and shaping) into one process step. This eliminates separate cutting operations and associated setup time, directly improving production efficiency while maintaining size precision
Solution Approach 2:
The invention merges the heat treatment process with the shaping process by incorporating the floating block mold into the heat treatment setup. This combination of operations reduces the total number of process steps and improves overall production efficiency
3Device complexity
If traditional mold structure is used, then simple design is maintained, but shaping precision and material utilization are insufficient
Solution Approach 1:
The floating block structure allows the mold to dynamically adapt to the workpiece during shaping. The block can float and adjust its position to accommodate variations in the hub geometry, improving shaping precision without requiring an overly complex fixed mold structure
Solution Approach 2:
The staggered bulge structure concentrates shaping action at specific locations where material removal is most effective. This local quality approach improves shaping precision by applying force where needed most, rather than distributing complexity throughout the entire mold structure
