Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.

Implementation Method 1
first recirculating ballscrews (13) with a substantially vertical arrangement... coupled to first nuts (not shown in the figures) associated with the bed (7)... in order to actuate the alternating translational motion thereof
Implementation Method 2
The supporting shaft of the upper roller is subjected to radial loads due to the contact reaction of the semi-finished product being worked, which tend to subject it to bending stresses
