Segmented Pressure Beam with Dynamic Closure for Sawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sawing devices, particularly panel dividing systems, pressure bars often collide with workpiece feed devices due to the need for optimal workpiece positioning, leading to suboptimal cutting quality and vibration during the sawing process.
Innovation Solution
The pressure bar is equipped with a closure device featuring a pressing surface that ensures additional pressing of the workpiece against the support table, providing continuous pressure support and sealing the feed-through openings to prevent dust and chips from adhering to the workpiece, while a suction device is integrated to enhance dust extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the workpiece feed device is positioned close to the sawing line for optimal material utilization, then material utilization is improved, but the pressure bar collides with the workpiece clamps causing vibration and reduced cutting quality
Solution Approach 1:
The pressure bar is segmented by introducing feed-through openings that allow the workpiece clamp to pass through. This segmentation enables the pressure bar to accommodate the clamp structure without collision, allowing the workpiece feed device to be positioned optimally for material utilization while maintaining cutting quality
Solution Approach 2:
The feed-through opening acts as an intermediary structure that mediates between the pressure bar and workpiece clamp. It allows the clamp to pass through the pressure bar region without causing collision, enabling close positioning of the feed device while maintaining structural integrity and cutting precision
2Object-affected harmful factors
If feed-through openings are provided in the pressure bar to allow workpiece clamp passage, then collision is avoided, but the suction channel becomes open allowing dust and chips to adhere to the workpiece
Solution Approach 1:
The closure device is designed to dynamically open and close the feed-through opening based on the position of the workpiece clamp. When the clamp approaches, the opening closes to maintain suction channel integrity and prevent dust adhesion. When the clamp needs to pass, the opening opens temporarily. This dynamic operation resolves the contradiction between collision prevention and dust prevention
Solution Approach 2:
The closure device operates in advance to close the feed-through opening before the workpiece clamp reaches the pressure bar region. This preliminary action ensures the suction channel remains sealed during the critical sawing operation, preventing dust and chips from adhering to the workpiece while allowing the clamp to pass through the opened state
3Object-generated harmful factors
If closure devices are used to seal the feed-through openings, then dust extraction is improved, but additional pressing force is needed to maintain continuous pressure support on the workpiece
Solution Approach 1:
The closure device is designed with dual functionality: it seals the feed-through opening to maintain suction channel integrity for dust extraction, and simultaneously provides pressing surfaces that apply additional pressing force to the workpiece. This multi-functionality resolves the contradiction by combining sealing and pressing actions in a single device, ensuring both dust extraction and continuous pressure support without requiring separate mechanisms

AI summary
The joist (1) has a movable bar that presses the saw workpiece (6) to a support table (7). The movable bar is provided with an aperture into which the workpiece clamper is inserted. The aperture is partially closed by the closure device. The closure device is provided for pressing the press surface (13) to press the saw workpiece to the support table of the sawing apparatus.
