Solution Overview

Problem

The increasing demand for motor core performance and the varying length of post-punching processing steps necessitate an improved degree of freedom in the arrangement of laminated body manufacturing apparatuses, as the preferred arrangement place changes frequently.

Innovation Solution

A laminated body manufacturing apparatus with a support portion disposed at the same height as or above the ground plane, allowing for easy rearrangement and integration with post-punching processing apparatuses on a common floor, and a conveyance system that includes elevating paths to facilitate efficient conveyance and access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the support portion is disposed below the ground plane, then the laminated body can be supported during punching, but the degree of freedom in arrangement is reduced

Engineering Contradiction:
Improvedegree of freedom in arrangementVSAvoidaccessibility to laminated body
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The support portion is positioned at the same height as or above the ground plane, utilizing the vertical dimension to provide support while maintaining horizontal accessibility. This dimensional change allows the support structure to be integrated into the same floor level as the die unit, improving arrangement flexibility without compromising operational access to the laminated body during punching operations

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the support portion is disposed above the ground plane, then the degree of freedom in arrangement is improved, but additional space requirements are introduced

Engineering Contradiction:
Improvedegree of freedom in arrangementVSAvoidspace requirements
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The support portion serves multiple functions: it supports the laminated body during punching, provides a platform for post-punching processing apparatus, and enables integration with conveyance systems. By making the support structure multi-functional, the patent reduces the need for separate dedicated spaces for each operation, thereby improving arrangement flexibility without proportionally increasing total space requirements

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A laminate manufacturing apparatus of the present disclosure comprises a die unit (10) that performs a stamping process using an upper die (11) and a lower die (12), a base (20) that has a ground-contact surface for a floor (FL) and supports the lower die (12), and a support unit (30) that supports, from below, a workpiece that has been stamped by the upper die (11) and the lower die (12). The lower end portion (301) of the support unit (30) is disposed on or higher than the ground-contact surface of the base (20), and lower than an upper surface (121) of the lower die (12).
