Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing sheet metal profiles for drawer slides are limited, as they can only form flanges from the edge of the sheet metal with smaller thicknesses, making them unsuitable for various applications, and there is a lack of disclosure on manufacturing sheet metal profiles or drawer slides using these methods.
Innovation Solution
A method to produce sheet metal profiles for drawer slides by laterally protruding webs from a flat surface, where the web is initially squeezed out and then reduced in width and increased in height through multiple process steps, allowing for customizable dimensions suitable for specific applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flange is formed from sheet metal edge using conventional method, then flange can be produced, but flange thickness is smaller than starting sheet metal thickness and flange can only be formed at edge area
Solution Approach 1:
The method performs preliminary squeezing of the web protrusion before final dimensioning. In the first method step, the web is squeezed out to create a protrusion with desired lateral extension. Subsequent method steps then refine this protrusion to achieve the precise final dimensions. This preliminary action allows the web to be formed at any location on the flat surface while maintaining dimensional precision through controlled subsequent deformation steps.
Solution Approach 2:
The manufacturing process is divided into multiple sequential method steps. The first step creates the web protrusion by squeezing material laterally, and subsequent steps independently adjust the web's width and height through additional squeezing operations. This segmentation of the forming process enables precise control over final web dimensions while maintaining flexibility in web location on the sheet metal profile.
2Manufacturing precision
If web is squeezed out and then squeezed together in multiple steps, then web width is reduced and height is increased to desired dimensions, but process complexity increases
Solution Approach 1:
The method systematically changes geometric parameters of the web through controlled material deformation. By applying squeezing forces in specific directions during different method steps, the process transforms the web from an initial protrusion state to a final state with precisely controlled width and height. This parameter control is achieved through progressive deformation that reduces width while simultaneously increasing height, allowing exact dimensional specification despite multiple process steps.
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
This method enables the production of sheet metal profiles with desired width and height parameters, suitable for use in drawer slides, overcoming the limitations of existing techniques by allowing web formation anywhere on the sheet metal surface and adapting dimensions as needed.
Implementation Method 1
at least one web that protrudes laterally, in particular vertically, and extends in the longitudinal direction of the sheet metal strand, is squeezed out of at least one flat surface of a sheet metal strand
Implementation Method 2
the at least one web is squeezed together in at least one further method step, preferably in 10 to 15 further method steps, is reduced in width and increased in height
