Section Bar Processing Machine Clamping Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing section bar processing machines are either expensive and complex due to multiple synchronized motors or prone to slippage and synchronization issues with non-motorized clamping vices, which compromise processing accuracy.
Innovation Solution
A machine design featuring two roller support devices with movable rollers, a feeding system with independent horizontal and vertical slides, and a combination of motorized and non-motorized clamping vices, where the non-motorized vice is locked to the track by a locking device, ensuring integral movement without slippage, and an overhead crane for cutting and milling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one clamping vice is motorised and the other is non-motorised, then cost and complexity are reduced, but slippage occurs and synchronization is compromised
Solution Approach 1:
The patent replaces the mechanical coupling system (where the second vice is dragged along the base) with a locking device that engages with a guide track. This substitution eliminates slippage while maintaining the cost advantage of having only one motorized vice, as the locking device provides reliable mechanical engagement without requiring additional motors.
Solution Approach 2:
The guide track acts as an intermediary element between the two clamping vices. The locking device on the second vice engages with this track, providing a stable reference that ensures synchronized movement without direct mechanical coupling between the vices themselves. This intermediary structure prevents slippage while maintaining system simplicity.
2Ease of operation
If three motors are used to move feeding unit and two clamping vices, then independent control is achieved, but cost and complexity increase
Solution Approach 1:
The patent merges the control functions by making the first and second clamping vices integral with each other through the locking device engagement with the guide track. This allows both vices to move together as a unified system, eliminating the need for separate motor control while maintaining synchronized operation. The single motorized vice provides sufficient control when combined with the mechanical coupling.
3Device complexity
If non-motorised clamping vice is dragged along base, then cost is reduced, but slippage occurs due to lubricating oil
Solution Approach 1:
The patent replaces the direct dragging mechanism (where the vice moves along the base surface) with a track-based system. The locking device engages with the guide track, providing a dedicated running surface that is not affected by lubricating oil on the base. This substitution maintains the non-motorized design while eliminating slippage caused by oily surfaces.

AI summary
In a machine for processing section bars (2), each section bar (2) is fed through a processing station (16) by a first motorised holding and transporting device (33) and a second holding and transporting device (34), which is selectively coupled to the first holding and transporting device (33) so as to be moved forward by said first holding and transporting device (33).
