Solution Overview

Problem

Conventional bending devices are unable to perform a 3-dimensional bending process simultaneously in up and down and side directions, leading to reduced productivity due to the need for multiple bending processes.

Innovation Solution

A bending device with a die frame, fixed and moving laminated moldings formed by slidably layered molding plates, and compression moldings that allow for simultaneous bending in up and down directions by using a moving cylinder and arrangement means to deform the moldings, enabling a single 3-dimensional bending process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional bending devices are used, then the bending process can be performed in traditional ways, but the productivity deteriorates due to requiring multiple bending processes for 3-dimensional bending

Engineering Contradiction:
Improvebending process efficiencyVSAvoidbending device structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The molding plates are divided into multiple segments that can slide relative to each other along guide rails. Each molding plate can independently deform to achieve bending in different directions (up-down and side directions simultaneously), enabling 3-dimensional bending in a single process while maintaining manageable device complexity through modular segmentation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The molding plates are designed with sliding capability along guide rails, allowing them to dynamically adjust their positions and deformation angles during the bending process. This dynamic configuration enables the device to achieve complex 3-dimensional bending trajectories while maintaining control over the bending forces applied to the workpiece

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If multiple bending processes are used for 3-dimensional bending, then the bending precision can be maintained, but the loss of time increases due to multiple processing steps

Engineering Contradiction:
Improvebending accuracyVSAvoidprocessing cycle time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

Multiple bending operations that would traditionally require separate processing steps are merged into a single simultaneous operation. The laminated molding structure with multiple slidable plates allows up-down bending and side bending to occur concurrently in one clamping cycle, eliminating the need for multiple sequential bending processes while maintaining precision through controlled deformation of each plate layer

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bending process achieves continuous deformation in multiple directions simultaneously rather than through discrete sequential steps. The sliding mechanism allows the molding plates to continuously adjust their deformation throughout the single clamping cycle, maintaining precise control over the bending trajectory while eliminating idle time between processing steps

Inventive Principle:
Principle #20Continuity of useful action

AI summary

The present invention relates to a bending device of which a beam is inserted between laminated moldings formed by slidably layering a plurality of molding plates, and the bending device of which deformation of the laminated moldings may simultaneously realize bending of up and down directions and side directions of a curved portion of a beam, and thus the bending device may realize a 3-dimensional bending process at once.
