Integrated Drilling Device for Section Member Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods require relocating large section members after cutting for drilling and beveling operations, resulting in inefficiencies and additional equipment needs.
Innovation Solution
A drilling device integrated within the cutting system, featuring swinging support arms with sliding rollers and controllable carriages and motors, allowing for perpendicular drilling and milling at section member vertex points without repositioning, accommodating various angles like 90° and 60°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If section members are cut by a band sawing machine and then relocated to another machine for drilling operations, then the drilling operation can be performed on cut section members, but additional equipment and repositioning are required which reduces efficiency
Solution Approach 1:
The patent combines the drilling device with the band sawing machine by integrating a carriage that travels along the sawing machine's support arms. This allows drilling operations to be performed at the cutting line without relocating section members to separate drilling machines, thereby eliminating the need for additional equipment and improving operational efficiency
Solution Approach 2:
The support arms of the band sawing machine are made multi-functional by adding a carriage that can perform both cutting and drilling operations. The carriage travels along the support arms and can position drilling tools at various locations, allowing the same equipment to handle multiple manufacturing operations without requiring separate dedicated machines
2Loss of time
If a drilling device is integrated within the cutting system with swinging support arms and controllable carriages, then drilling and milling can be performed directly at the cutting line without repositioning section members, but the device structure becomes more complex
Solution Approach 1:
The patent employs dynamic support arms that can swing and adjust their position, allowing the carriage to reach different locations along the section member. This dynamic capability enables the drilling device to adapt to various cutting positions and section member orientations without requiring complex fixed positioning mechanisms or repositioning of the section members themselves

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient drilling and milling of section member side portions directly in the cutting line, reducing equipment needs and improving workflow by maintaining the drilling tool's perpendicular alignment with the section member sides.
