Solution Overview
Problem
The existing workpiece machining apparatuses are heavy due to thick plate-shaped members, leading to inconvenience and potential deterioration in machining quality due to deformation when flexible members are used.
Innovation Solution
A workpiece machining apparatus with a first and second plate-shaped member, where a first pressure member and a second pressure member apply pressures to specific portions, and changing units align the pressurized areas to maintain machining quality while reducing weight by adjusting the position of the second pressure member relative to the first pressure member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thick plate-shaped abutment member is used to support the machining member, then the machining quality is maintained by preventing protrusion of cutting blades and creasers, but the apparatus becomes heavy and causes inconvenience
Solution Approach 1:
The patent divides the single thick abutment member into two separate thin plate-shaped members (first and second plate-shaped members) positioned on opposite sides of the machining member. This segmentation allows each plate to be thin and lightweight while collectively providing the support function that previously required a single thick plate, thus reducing overall apparatus weight while maintaining machining quality.
Solution Approach 2:
The patent transitions from a single-dimensional thick plate structure to a two-dimensional configuration with two thin plates positioned on opposite sides. By distributing the support function across two dimensions (above and below the machining member), the system achieves the same structural support with reduced material thickness and weight in each individual component.
2Weight of stationary object
If flexible plate-shaped members are used to reduce weight, then apparatus weight is reduced, but the members may deform when pressure member positions are changed, deteriorating machining quality
Solution Approach 1:
The patent combines the functions of two thin plate-shaped members (first and second plate-shaped members) positioned on opposite sides to collectively provide the support and stabilization function. By merging their support actions from both sides, the system achieves the same functional outcome as a single thick plate, preventing deformation even when the members are flexible and lightweight.
Solution Approach 2:
The patent applies pressure members (first and second pressure members) that can be positioned beforehand on the respective plate-shaped members to prevent deformation before machining operations begin. This prior application of controlled pressure stabilizes the flexible plates, preventing quality deterioration while allowing the use of lightweight flexible members.
3Adaptability or versatility
If the position of the first pressure member is changed on the first plate-shaped member, then adaptability is improved, but the second plate-shaped member deforms, deteriorating machining quality
Solution Approach 1:
The patent employs dynamic positioning capabilities for both the first pressure member on the first plate-shaped member and the second pressure member on the second plate-shaped member. This allows both pressure members to be adjusted independently to different positions, providing adaptability for various machining configurations while the opposing plate structure prevents deformation that would compromise quality.

Function Achieved in This Case
This configuration allows for weight reduction and minimizes the risk of machining quality deterioration by ensuring proper alignment and pressure distribution, even when the apparatus components are flexible, thus maintaining efficient machining performance.
Implementation Method 1
a first pressure member for applying a first pressure directed from the one first principal surface side toward the other first principal surface side to a portion of the one first principal surface; a second pressure member for applying a second pressure directed from the other second principal surface side toward the one second principal surface side to a portion of the other second principal surface

AI summary
A pressure plate 12 has an upper surface 12a and a lower surface 12b. A blade die unit 16 for machining a workpiece by applying a pressure to a principal surface of the workpiece is arranged on the lower surface 12b. A face plate 24 has an upper surface 24a and a lower surface 24b, and is arranged such that the upper surface 24a faces the lower surface 12b with the blade die unit 16 interposed therebetween. An upper pressure roller 20 applies a pressure directed from the upper surface 12a side toward the lower surface 12b side of the pressure plate 12 to a portion of the upper surface 12a. A lower pressure roller 22 applies a pressure directed from the lower surface 24b side toward the upper surface 24a side of the face plate 24 to a portion of the lower surface 24b. A motor changes a portion that the upper pressure roller 20 pressurizes, and also, a portion that the lower pressure roller 22 pressurizes is changed such that the portion that the lower pressure roller 22 pressurizes is aligned with the portion that the upper pressure roller 20 pressurizes when viewed from a direction crossing the lower surface 24b.
