Segmented Lower Jacking Member for Stable Wire Withdrawal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squaring machines face challenges in stabilizing edge scraps during the wire withdrawal process, as the structural limitations of upper and lower jacking members make it difficult to ensure axial fixation, leading to issues like lateral tipping and instability.
Innovation Solution
A lower jacking member with at least two single components, each connected to a drive structure, is used to abut against the bottom surface of edge scraps, with varying spacings from the cutting edge, and a sequence control mechanism to manage vertical displacement of pressing blocks, ensuring stable wire withdrawal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional single-component jacking member is used, then the device complexity is low, but the edge scrap stability during wire withdrawal is insufficient
Solution Approach 1:
The jacking member is divided into multiple single components (first single component, second single component, etc.) arranged along the axial direction. Each component has independent drive structures that can be controlled separately. This segmentation allows different components to perform different functions: some components press against the edge scrap to prevent tipping, while others provide support or positioning, thereby improving stability without requiring a single complex structure
Solution Approach 2:
Different single components are positioned at different locations along the axial direction with different spacings from the cutting edge. The drive structures are independently connected to provide localized control. This local quality approach allows each component to be optimized for its specific function at its specific location, with closer components providing stronger pressing force near the cutting edge and farther components providing support at distances
2Reliability
If multiple single components with independent drive structures are used, then the edge scrap stability is improved, but the device complexity increases
Solution Approach 1:
The drive structures are segmented into independent units, each connected to a specific single component. This allows independent control of each component's pressing action, enabling precise control over the jacking process and improving reliability while keeping each individual drive unit relatively simple
Solution Approach 2:
The system allows dynamic control of the multiple single components through independent drive structures. The components can be activated sequentially or simultaneously based on the wire withdrawal process requirements, enabling adaptive response to different process conditions while maintaining structural simplicity in each individual component
3Reliability
If sequence control of pressing blocks is implemented, then the wire withdrawal stability is improved, but the control complexity increases
Solution Approach 1:
The sequence control is designed to activate pressing blocks in a predetermined order based on their spacing from the cutting edge. Components closer to the cutting edge are activated first to provide immediate support during the critical wire withdrawal phase, followed by activation of farther components. This preliminary sequencing ensures stable wire withdrawal while using simple control logic based on spatial positioning

AI summary
Disclosed are a lower jacking member, a wire withdrawal method based on the lower jacking member, and a squaring machine including the lower jacking member. The lower jacking member is used for axially fixing a bottom surface of an edge scrap formed by cutting a round rod, and a bottom outline of the edge scrap has a cutting edge. The lower jacking member includes at least two single components, and drive structures independently connected to the single components. A spacing between at least one of the single components and the cutting edge is different from a spacing between the rest of the single components and the cutting edge; and the drive structures are used for driving tops of the single components to abut against the bottom surface of the edge scrap.
