Sliding Spindle Support Bench for Stable Pipe Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pipe bending machine structure is overly complex due to interconnected parts that create unnecessary constraints, affecting stability and functionality.
Innovation Solution
Structurally separating the bending unit from the pipe support arm and using a spindle with a sleeve member and rotatable spindle frame mounted on a platform with spherical supports to allow free sliding on a support bench, reducing component parts and enabling stable support during bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the support arm and small arms are interconnected to sustain the support arm, then the support arm can be sustained during oscillation, but the structure becomes complex and creates unnecessary constraints
Solution Approach 1:
The invention extracts and removes the small arms from the system. Instead of having the bending unit sustain the support arm through interconnected small arms, the support arm is allowed to oscillate freely under gravity. This eliminates the complex interconnected structure while maintaining the necessary support function during the bending operation.
2Adaptability or versatility
If the spindle is mounted oscillating on the support arm, then the spindle follows the oscillation of the pipe, but the spindle structure becomes more complex and stability is reduced
Solution Approach 1:
The invention introduces a spherical support as an intermediary between the spindle and the support arm. This spherical support acts as a mediator that allows the spindle to follow the oscillation of the pipe while maintaining stable support. The spherical geometry enables smooth tracking of pipe position changes without creating complex mounting mechanisms.
3Reliability
If multiple small arms are connected to both the bending unit and support arm, then the support arm can be sustained, but unnecessary constraints are created that affect functionality
Solution Approach 1:
The invention removes the small arms that create unnecessary constraints. By eliminating these intermediate connecting elements, the system gains functional flexibility while maintaining reliability through direct gravitational support of the support arm during oscillation.

AI summary
An assembly of a machine for bending an elongated piece (T) and relevant support bench is described. The elongated piece (T) is supported by a spindle (3) that comprises a sleeve member (4) suitable to be connected to the elongated piece (T) to be bent, and a spindle frame (5) which rotatably supports the sleeve member (4). The spindle frame (5) is mounted on a platform (6) provided at its bottom with at least a spherical support (7) so that the spindle (3) is able to slide freely on a support bench (2), while the elongated piece (T) is bent.
