Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The C-shaped frame structure in press apparatuses experiences elastic deformation and axis displacement during workpiece pressing, making it challenging to maintain processing accuracy, and increasing the frame's thickness to mitigate this is limited by miniaturization and cost constraints.
Innovation Solution
A C-shaped frame structure with a specific configuration where the lower frame is supported movably in the upward and downward direction, and the frame is designed to elastically deform by tilting its components to minimize axis displacement between the fixed and movable dies, allowing for effective cancellation of displacements through balanced tilting angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the thickness of the C-shaped frame is increased to minimize elastic deformation, then processing accuracy is improved, but the apparatus size and cost increase
Solution Approach 1:
The C-shaped frame is divided into multiple segments (first C-shaped frame, second C-shaped frame, third C-shaped frame) connected by coupling portions. This segmentation allows each segment to be optimized independently and enables the frame to deform elastically in a controlled manner to cancel axis displacement, achieving high processing accuracy without increasing overall frame thickness.
Solution Approach 2:
The invention changes the structural parameters of the frame by introducing coupling portions with specific rigidity and allowing controlled elastic deformation of frame segments. By adjusting the rigidity distribution and deformation characteristics, the frame can compensate for axis displacement under load, maintaining processing accuracy without increasing frame volume.
2Manufacturing precision
If the thickness of the C-shaped frame is increased to minimize elastic deformation, then processing accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The frame is segmented into multiple parts that can be manufactured separately and assembled. This allows for cost-effective production of individual components with optimized thickness, avoiding the need to manufacture a single thick frame structure, thereby reducing material costs and manufacturing complexity.
Solution Approach 2:
The invention introduces dynamic elastic deformation capabilities to the frame structure through coupling portions. This allows the frame to adaptively compensate for displacement under load through controlled deformation, replacing the need for a statically rigid (thicker) frame, thus reducing material usage and manufacturing cost while maintaining accuracy.
3Manufacturing precision
If a mechanism is incorporated to prevent axis displacement, then processing accuracy is improved, but device complexity increases
Solution Approach 1:
The invention merges the function of preventing axis displacement into the frame structure itself through the coupling portions and elastic deformation mechanism. Instead of adding a separate compensation mechanism, the frame's own structural features (coupling portions, segment rigidity) perform the displacement cancellation function, simplifying the overall device complexity.
Solution Approach 2:
The frame structure serves itself by using its own elastic deformation capability to cancel axis displacement. The coupling portions and frame segments automatically adjust under load to maintain alignment, eliminating the need for external compensation mechanisms or complex control systems.

AI summary
A frame structure includes a C-shaped frame having a front side that opens in a forward and rearward direction among the forward and rearward direction, a leftward and rightward direction and an upward and downward direction, which are perpendicular to each other, an upper action section supported by an upper front portion of the C-shaped frame, and a lower action section supported by a lower front portion of the C-shaped frame, wherein, when a reaction force is applied through the upper action section, the C-shaped frame is deformed such that a displacement of the upper action section in the forward and rearward direction, which occurs according to an elastic deformation of the C-shaped frame, is canceled out and such that a displacement of a pivotal movement about a leftward and rightward direction axis of the upper action section is canceled out.
