Ceramic Slide Plates for Profile-Rolling Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile-rolling machines with bronze carriage and nitrided track slide plates are sensitive to wear and require complex and costly lubricant management, as they function optimally only with pure lubricants and are prone to dirt penetration.
Innovation Solution
The use of ceramic or non-metallic materials for the slide plates, either entirely or through coatings, reduces wear and improves lubrication behavior, allowing for a closed lubricant system and the use of a combined coolant and lubricant medium, which reduces costs and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bronze carriage slide plates and nitrided track slide plates are used, then sliding function is achieved, but the system becomes sensitive to wear and requires complex lubricant management
Solution Approach 1:
The patent applies composite materials by combining ceramic materials (such as silicon carbide or aluminum oxide) with metal substrates to create slide plates that exhibit both the hardness and wear resistance of ceramics and the toughness and ductility of metals. This composite structure eliminates the need for complex lubricant management while providing superior wear resistance compared to conventional bronze or nitrided steel slide plates.
Solution Approach 2:
The patent substitutes the mechanical lubrication system with a self-lubricating ceramic-based slide plate system. The ceramic material inherently provides low friction and wear properties without requiring external lubricants, thereby replacing the complex lubricant management system with a simpler, maintenance-free mechanical solution.
2Ease of operation
If pure lubricant is used with conventional slide plates, then sliding function is maintained, but the lubricant requires collection, purification, and return in a closed system
Solution Approach 1:
The ceramic-based slide plates are self-lubricating, meaning they inherently provide the necessary lubrication for sliding operations without requiring external lubricant supply systems. The material composition and surface properties of the ceramic plates enable them to reduce friction and wear autonomously, eliminating the need for lubricant collection, purification, and return systems.
3Reliability
If conventional slide plates are used, then the system is sensitive to dirt penetration, but ceramic or non-metallic materials significantly reduce this sensitivity
Solution Approach 1:
The patent uses composite materials consisting of ceramic particles or layers combined with metal matrices to create slide plates that are highly resistant to dirt penetration. The ceramic component provides hardness and chemical inertness, preventing dirt and contaminants from adhering to or penetrating the slide surface, while the metal matrix ensures structural integrity and ease of manufacturing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces wear and sensitivity to dirt, enabling the reuse of lubricants and the integration of coolant and lubricant functions into a single system, thereby saving costs and simplifying maintenance.
Implementation Method 1
the pair of slides formed in this way is both significantly less susceptible to wear and also significantly less sensitive with regard to its lubrication behavior
Implementation Method 2
the pair of slides formed in this way is both significantly less susceptible to wear
Implementation Method 3
The use of a lubricant between the pair of slides advantageously reduces the friction resistance between it
Implementation Method 4
the pair of slides made according to the invention also allows the use of a combined coolant and lubricant medium, i.e. a medium that fulfills both cools and lubricates

AI summary
The invention relates to a profile-rolling machine for rolling a profile in a blank, wherein the profile-rolling machine has a first and a second profile-rolling jaw. The second profile-rolling jaw (126) is guided—held by a carriage (124)—in a guide track (130) relative to the first profile-rolling jaw (110) for the purpose of rolling the profile into the blank. The carriage (124) has a carriage slide plate (122) and the guide track (130) has a guide slide plate (132). The two slide plates together form a sliding pairing and slide on each other. In order to render said sliding pairing less susceptible to dirty lubricant and less susceptible to wear, it is proposed according to the invention to manufacture the guide slide plate (132) and/or the carriage slide plate (122) at least partially from ceramic or from a non-metallic material or to coat the same with such materials.
