Section Bar Work Centre Clamping for Wide Profiles and Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work centers for processing section bars, particularly those made of aluminum, light alloys, or PVC, face challenges in securely holding wide section bars and preventing vibrations from affecting processing precision due to limitations in clamping vice jaw design.
Innovation Solution
The work center incorporates a U-shaped base with longitudinal guide members, a gantry overhead crane, and adjustable cross members with clamping vices featuring elastically deformable bumpers and a support system that includes rotating rollers and pneumatically controlled support blocks to ensure secure holding and precise processing of wide section bars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional clamping vices with fixed jaw configuration are used, then the device structure remains simple, but wide section bars cannot be securely held and vibrations affect processing precision
Solution Approach 1:
The clamping vice is divided into multiple independent components: a first clamping jaw, a second clamping jaw, and at least one intermediate jaw positioned between them. Each jaw can be independently adjusted along the cross member to provide multiple clamping points across the width of the section bar, enabling secure holding of wide sections while maintaining structural modularity
Solution Approach 2:
The jaws are designed with adjustable positions along the cross member rather than being fixed. This dynamic configuration allows the clamping vice to adapt to different section bar widths and provide optimal clamping distribution, preventing vibrations during processing while accommodating varying workpiece dimensions
2Stability of the object's composition
If the number of clamping points is increased to secure wide section bars, then holding stability improves, but the device complexity and adjustment difficulty increase
Solution Approach 1:
The cross member serves multiple functions: it acts as a structural support element, a guide rail for jaw movement, and an adjustment mechanism backbone. The jaws can move along the entire length of the cross member, providing universal clamping capability across different positions and widths, simplifying the adjustment process while maintaining holding stability
Solution Approach 2:
The system allows continuous adjustment of jaw positions along the cross member, changing the spatial parameters of clamping points. This enables optimization of clamping distribution for different section bar widths and materials, achieving stable holding without requiring complex discrete adjustment mechanisms
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 configuration effectively secures wide section bars and minimizes vibrations, ensuring precise processing by providing a stable support surface that adjusts to accommodate varying widths and maintains processing accuracy.
Implementation Method 1
Each jaw is provided with a bumper, which is made of an elastically deformable material and is designed to cooperate with a lateral face of the section bar
Implementation Method 2
a support roller, which extends through the two jaws in the second direction and defines, together with the other support rollers, a support surface for the section bar

AI summary
A work centre to process section bars (2) has an elongated base (3) and a plurality of cross members (11), each of which is mounted on the base (3) and supports at least one first support member (25) defining a first support surface (PI) for the section bars (2), a clamping vice (22) provided with two jaws (23, 24), which are movable relative to one another between a clamping position and a release position to clamp and release the section bars (2), and at least one second support member (34, 37), which defines a second support surface (P2) for the section bars (2), is connected to a pneumatic suction device and is movable between a lowered position, in which the second support surface (P2) extends under the first support surface (PI), and a lifted position.
