Pipe Cutting Chuck Layout for Two-Sided Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices struggle with machining non-straight or heavy elongate work pieces, and require repositioning for machining both sides of work pieces.
Innovation Solution
A device with movable secondary chucks and supports, allowing for both rotational and conveyor modes, enabling cutting of non-rotatable and rotatable elongate work pieces, and featuring movable supports to clear the path for the trolley.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the work piece is positioned on a table and cut from one side, then cutting operation is simple, but machining both sides requires repositioning the work piece
Solution Approach 1:
The device adds the dimension of work piece rotation around its longitudinal axis. By rotating the work piece in place during cutting, both sides become accessible to the cutting tool without requiring physical repositioning of the work piece on the table, thus saving time while maintaining operational simplicity.
2Stability of the object's composition
If secondary chucks have substantial height for work piece support, then work piece support stability is improved, but movement between stored and support positions becomes more complex
Solution Approach 1:
The secondary chucks are extracted from the main chuck assembly and positioned on separate movable supports. This separation allows the secondary chucks to be independently moved between stored and support positions, reducing the complexity of integrating their movement with the main chuck while maintaining substantial height for stable work piece support.

AI summary
The invention relates to a device for cutting elongate work pieces, such as pipes and profiles, which device comprises: - an elongate machine bed; - a trolley having a main rotatable chuck for rotating an elongate work piece held in the main rotatable chuck, which trolley is movable over the machine bed in longitudinal direction; - at least two secondary chucks having a through hole for rotatably supporting an elongate work piece held by the main rotatable chuck, which at least two secondary chucks are arranged on the elongate machine bed space apart from each other; - a cutting station for cutting an elongate work piece held in the main rotatable chuck, which cutting station is arranged adjacent the machine bed; and - at least two supports having a number of rollers for supporting an elongate work piece held by the main chuck, which at least two supports are arranged on the elongate machine bed spaced apart from each other; wherein the at least two secondary chucks are movable between a support position, in which the elongate work piece can extend through the through hole of and be supported by the secondary chuck, and a stored position, in which the at least secondary chucks are positioned outside of the path of the elongate work piece; and wherein the at least two supports are movable between a support position, in which the elongate work piece is supported onto the rollers of the support, while the elongate work piece is held by the main chuck, and a stored position, in which the at least two supports are positioned outside of the path of the elongate work piece.
