Tube Flaring Tool With Movable Punch Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tube flaring tools require multiple punches and an additional positioning member, making the process inconvenient for users as they need to secure a specified tube length and operate multiple punches for flaring.
Innovation Solution
A tube flaring tool with a carrier and a movable punch assembly that allows for straight, curved, or rotational movement to align punches with the tube, enabling a single punch to flare the tube to a predetermined length without the need for multiple punches or positioning adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional flaring tool uses a single punch, then the operation is simpler, but it cannot flare the tube to the final shape and size
Solution Approach 1:
The punch assembly is designed to be movable relative to the carrier, allowing the punch to be positioned at different locations. The punch can be moved to a first location for preliminary flaring and to a second location for final flaring, enabling multi-stage flaring operations with a single punch through dynamic repositioning.
2Manufacturing precision
If multiple punches are used to flare the tube, then the flaring precision is improved, but the device complexity increases
Solution Approach 1:
The punch assembly includes a punch holder with multiple punches arranged at different locations, and a movable punch that can be selectively positioned. This segments the flaring function into multiple discrete punch locations while maintaining a unified movable structure, allowing precise multi-stage flaring without requiring multiple separate tools.
Solution Approach 2:
A single movable punch serves multiple functions by being repositionable to different locations on the punch holder. The same punch can perform preliminary flaring at one location and final flaring at another location, making one component perform the work of multiple fixed punches.
3Manufacturing precision
If a positing member is used to keep the tube with specified length, then the flaring precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The tube itself serves as the positioning element by being inserted into the clamping assembly where it is automatically secured at the correct position. The tube's own geometry and the clamping assembly's design work together to establish the proper tube end position without requiring separate positioning members or additional adjustment operations.

AI summary
A tube flaring tool, which is adapted to clamp a tube and align the tube with a punch driver, includes a carrier having a clamping assembly slot and a punch assembly slot; a clamping assembly received in the clamping assembly slot of the carrier to clamp a tube; and a punch assembly having a main member and a plurality of punches movably coupled to the main member. The main member is movably received in the punch assembly slot, so that the main member of the punch assembly is able to be moved to select one of the punches to flare the tube.
