Solution Overview

Problem

Existing rolling machines for assembling heat-cut profiles have limited adjustability of roller positions, making it difficult to accommodate profiles of different extensions and weights, and the working area is not easily accessible, complicating the assembly process.

Innovation Solution

A rolling machine with adjustable working assemblies featuring rollers at different elevations and offset parallel working axes, supported by extensive actuation means, including motors and gear systems, allowing for flexible positioning and easy access to the working area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the supporting shaft of the upper roller has a smaller diameter than the hollow shaft, then the upper roller can be supported in rotation inside the hollow shaft, but the length of the protruding shaft section must be limited to avoid excessive deformations under radial loads

Engineering Contradiction:
Improveroller support structureVSAvoidwork elevation adjustment range
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The invention replaces the fixed cantilever shaft support with a dynamic adjustment mechanism. The upper roller's supporting shaft is made adjustable along the hollow shaft axis through actuation means, allowing the work elevation to be dynamically changed while maintaining structural integrity. This resolves the contradiction by enabling both compact shaft design and wide adjustment range without excessive deformations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the parameter of shaft position along the hollow shaft axis. By making the supporting shaft position adjustable rather than fixed, the system can optimize the protruding length to avoid excessive deformations while achieving wide work elevation adjustment range. The actuation means enables controlled parameter changes to adapt to different profile requirements.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If the working assembly has limited adjustment of roller elevations, then the structure remains simple, but it is difficult to accommodate profiles of different extensions and weights

Engineering Contradiction:
Improveroller support structureVSAvoidprofile accommodation capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The invention introduces dynamic adjustability to both upper and lower roller elevations. The upper roller supporting shaft is adjustable along the hollow shaft axis, and the lower roller supporting shaft is adjustable along its own axis. This dynamic capability allows the working assembly to adapt to profiles of different extensions and weights while maintaining relatively simple actuation means.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention creates a universal working assembly that can handle multiple profile types. By providing adjustment means for both upper and lower rollers, the same working assembly can accommodate various profile configurations (different extensions, weights, and geometries) without requiring dedicated support apparatuses for each specific profile type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If the support apparatuses are arranged above the rollers, then the structure is stable, but the working area becomes less accessible

Engineering Contradiction:
Improveroller support stabilityVSAvoidworking area accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The invention inverts the conventional arrangement by placing the actuation means below the rollers rather than above them. The first actuation means is arranged below the first roller to actuate its supporting shaft, and the second actuation means is arranged below the second roller. This inversion maintains structural stability while significantly improving working area accessibility for profile loading and unloading.

Inventive Principle:
Principle #13The other way round (Inversion)
