Solution Overview

Problem

Existing die press assemblies for powder pressing of carbide steel inserts require frequent manual intervention for exchanging dies and punches, limiting batch production efficiency and necessitating multiple sizes of inserts in stock.

Innovation Solution

A die press assembly with a radial locking pin system that allows the die, lower punch, and core pin to be clamped and held together as a single unit, enabling automatic handling and exchange using a robot gripper, where the locking pin engages recesses in each component for secure alignment and movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual handling and exchanging of die and punches is used, then操作简单性 is maintained, but productivity is reduced and time loss increases

Engineering Contradiction:
Improveproduction batch timeVSAvoidautomatic changing capability
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The die, lower punch, and core pin are merged into a single integrated assembly that can be handled as one unit. The locking pin system combines multiple components (die, punch, core pin) into a unified structure that enables automated gripping and exchange by robot grippers, eliminating manual intervention and enabling high-speed automatic changing.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If frequent exchange of die and punches is required, then adaptability is improved, but time loss and productivity are worsened

Engineering Contradiction:
Improveinsert size variation capabilityVSAvoidexchange time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system is segmented into interchangeable assemblies, each configured for a specific insert size. The die assembly (comprising die, lower punch, and core pin as one unit) can be quickly exchanged for another assembly of different size configuration. This segmentation enables rapid switching between different insert sizes without manual disassembly or adjustment.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple sizes of inserts are kept in stock, then adaptability is improved, but quantity of substance increases

Engineering Contradiction:
Improveinsert size availabilityVSAvoidinsert stock quantity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Instead of maintaining physical stock of multiple insert sizes, the system changes the parameters of the die assembly itself. By exchanging entire die assemblies with different dimensional parameters (size, shape, configuration), the system provides adaptability for various insert sizes without requiring physical inventory of each variant. This reduces stock requirements to essentially one unit per assembly type.

Inventive Principle:
Principle #35Parameter changes
