Rolling Stand Support Frame With Replaceable Spacer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling stands face challenges in simplifying and ensuring precise, repeatable equipping of chocks during roll movement and replacement, leading to reduced accuracy and quality in rolled metal products due to complex and error-prone adjustment processes.
Innovation Solution
A support frame with a first and second shoulder, mounted on a mobile slider, and a replaceable spacer element that defines the desired distance between the shoulders, allowing for simplified and repeatable positioning of chocks without cascade adjustments, enabling standardized and automatic operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cascade adjustment of chocks is performed sequentially (lower horizontal roll first, then vertical rolls, then upper horizontal roll), then the positioning can be completed step by step, but the operating time increases and positioning accuracy decreases due to accumulation of errors
Solution Approach 1:
The support frame is segmented into multiple independent support elements (first support element, second support element, third support element) that can be independently positioned and adjusted. Each support element has its own adjustment mechanism, allowing simultaneous independent adjustment of multiple chocks rather than sequential cascade adjustment. This segmentation enables parallel operation, reducing total equipping time while maintaining positioning accuracy through individual adjustment control.
2Adaptability or versatility
If independent adjustment of each chock position is allowed, then flexibility in positioning is improved, but the complexity of the equipping operation increases
Solution Approach 1:
The support frame employs universal support elements that can accommodate different types of rolls (horizontal and vertical rolls) at different positions. Each support element is designed with multi-functional capability to support various roll configurations through standardized interfaces and adjustment mechanisms. This universality provides flexibility in positioning while reducing operational complexity through standardized procedures and components that can be reused across different roll configurations.
3Adaptability or versatility
If the reciprocal distance between vertical rolls needs to be adjusted, then the positioning references of all chocks must be moved, but this increases the risk of accidental modification and reduces repeatability
Solution Approach 1:
The support frame incorporates pre-positioned support elements with predetermined positions and spacing. When adjusting the reciprocal distance between vertical rolls, only the specific support elements related to vertical rolls need to be moved, while other support elements remain in their pre-positioned locations. This preliminary positioning of reference elements reduces the risk of accidental modification and improves repeatability, as the unchanged support elements serve as stable reference points for subsequent positioning operations.

AI summary
Support frame (10) for a rolling stand, in which a first horizontal rolling roll (22) and a second horizontal rolling roll (23) are provided, opposite each other with respect to a nominal rolling axis (X). The first horizontal roll (22) is supported at its ends by two first chocks (22a, 22b) and the second horizontal roll (23) is supported at its ends by two second chocks (23a, 23b). The support frame (10) comprises a first shoulder (1 1) disposed on a first side with respect to the nominal rolling axis (X) so as to maintain in a determinate position one of the first chocks (22a) and one of the second chocks (23 a), and a second shoulder (12) disposed on a second side opposite the first side with respect to the nominal rolling axis (X), so as to maintain, in coordinated positions with respect to the first shoulder (1 1), the other of the first chocks (22b) and the other of the second chocks (23b). The support frame (10) comprises a spacer element (19) of the replaceable type interposed between the two shoulders (1 1, 12) so as to define a desired and modifiable reciprocal distance between the two shoulders (1 1, 12).
