Welded Wire Mesh Bending Head With Variable Bending Trajectory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bending heads for welded wire mesh have limited bend capabilities due to fixed bending trajectories, require large movement spaces and installation spaces, leading to inefficiencies and safety concerns.
Innovation Solution
The bending head features a support with a separate drive system, allowing independent adjustment of the bending arm and support, enabling a variable bending trajectory and reducing the required movement and installation spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed bending trajectory is used to simplify the control mechanism, then the device complexity is reduced, but the adaptability for different wire parameters and bend types is limited
Solution Approach 1:
The bending trajectory is made dynamically adjustable through the control unit, which coordinates the first and second drive devices to move the bending arm along different trajectories based on the selected bend type and wire parameters, rather than using a fixed mechanical trajectory
2Manufacturing precision
If a large movement space is provided for the bending arm to achieve full bending range, then the bending precision is improved, but the installation space requirement increases
Solution Approach 1:
The bending arm is enabled to move in multiple dimensions through the coordinated action of the first drive device (rotating the bending arm about a first axis) and the second drive device (moving the bending face along a trajectory), allowing precise bending control within a compact installation footprint
3Ease of operation
If a large table cutout is made to accommodate the bending arm movement, then the bending arm has sufficient movement space, but the bracing of the welded wire mesh becomes insufficient leading to sagging
Solution Approach 1:
The drive system is segmented into two independent drive devices: the first drive device controls the rotational movement of the bending arm, while the second drive device controls the movement of the bending face along the trajectory. This segmentation allows the bending arm to have sufficient movement space without requiring a large table cutout, as the bending face movement is controlled independently

AI summary
A bending head for welded wire mesh includes a frame, a bending face to be moved relative to the frame for bending a wire in a welded wire mesh, a counterholder on which the wire can be braced during bending by the bending face, a bending die which, at least in part, has a predefined bending radius, a bending arm on which the bending face is arranged, and an arm drive device with which the bending arm can be adjusted relative to the frame. A support is provided at which the bending arm is movably mounted. A support drive device, with which the support can be adjusted relative to the frame and which is separate from the arm drive device, is provided.
