Solution Overview
Problem
Existing press quenching devices can only process a single target object at a time, limiting the ability to perform batch processing of multiple objects simultaneously, and there is a need for a method and device that can perform press quenching on multiple objects while minimizing deformation.
Innovation Solution
A quenching method and restraint quenching device that allows for the simultaneous processing of multiple objects by switching between restraint and unrestraint states, using positioning and restraint members to maintain object positions and prevent deformation during cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a press quenching device is designed to process multiple target objects simultaneously, then productivity is improved, but device complexity increases
Solution Approach 1:
The device is divided into multiple independent restraint quenching units, each capable of processing one target object. This segmentation allows the device to handle multiple objects simultaneously while keeping each unit's structure relatively simple and manageable.
Solution Approach 2:
Each restraint quenching unit is designed with universal functionality to process various target objects through standardized restraint and quenching mechanisms, enabling batch processing without requiring entirely different device configurations for each object type.
2Manufacturing precision
If restraint is applied to prevent deformation during quenching, then manufacturing precision is improved, but the quenching process becomes more complex
Solution Approach 1:
The restraint members are pre-positioned on the target objects before the quenching process begins. This preliminary positioning ensures that the objects are properly constrained to prevent deformation during cooling, while simplifying the overall process by combining positioning and restraint functions.
Solution Approach 2:
Restraint members act as intermediary elements between the quenching medium and the target objects. These members transmit the quenching medium's cooling effect while simultaneously providing mechanical restraint to prevent deformation, thus mediating between the conflicting requirements of rapid cooling and shape stability.
