Tube Cutting with Fixing Element to Prevent Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cutting tubes to length face challenges in preventing the displacement of the tube fixing element with respect to the tube sheathing or the inner tube when a clamping sleeve is applied, leading to insecure clamping and potential collisions during crimping.
Innovation Solution
The method involves using a severable tube fixing element that completely encloses the outer tube sheathing in the circumferential direction, such as single-sided adhesive tape, shrink tubes, or injection-molded surrounds, to prevent relative displacement by ensuring secure adhesion and positioning, and employing cutting tools that develop heat to fuse components for secure bonding.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the clamping sleeve is produced with a significantly greater inner diameter to avoid collision during pushing-on, then the risk of collision between braiding ends and clamping sleeve is reduced, but the radial distance increases causing disadvantageous effects in the subsequent crimping operation
Solution Approach 1:
The tube fixing element is applied to the tube before the clamping sleeve is pushed on. This preliminary action secures the tube sheathing and inner tube in position, preventing displacement during the pushing-on operation, thereby allowing the use of a clamping sleeve with appropriate inner diameter without excessive radial distance
2Ease of manufacture
If the clamping sleeve inner diameter is adapted closely to the tube outer diameter to improve crimping, then the radial distance is minimized for better crimping, but the tube fixing element may be pushed back with respect to the tube sheathing causing insecure clamping
Solution Approach 1:
The tube fixing element is applied in advance to secure the tube components before the clamping sleeve is installed. This preliminary securing action prevents the tube fixing element from being pushed back during the pushing-on operation, ensuring reliable clamping while allowing optimal crimping geometry
3Ease of operation
If the tube fixing element is not secured against displacement, then the application process is simpler, but the tube sheathing may displace with respect to the inner tube leading to insecure clamping
Solution Approach 1:
The tube fixing element acts as an intermediary component that is applied to the tube sheathing and inner tube. It provides a simple application process while simultaneously preventing displacement of the tube components, thereby ensuring secure clamping without complex procedures

AI summary
A method for cutting to length a piece of tube having an inner tube and an outer tube sheathing, the piece of tube being detached with the aid of a cutting tool at a cutting site in a plane oriented transversely to the longitudinal extent of the tube. The tube sheathing is surrounded by a severable tube fixing element, which covers over the intended cutting site before the piece of tube is detached using the cutting tool at the cutting site, and the tube fixing element completely encloses the outer tube sheathing in the circumferential direction. The tube fixing element is fixed on the tube sheathing and/or the tube enclosed by the tube fixing element is severed with the cutting tool such that a relative displacement of the tube fixing element with respect to the tube sheathing or of the tube sheathing with respect to the inner tube is prevented.
