Gripping Head Workpiece Feed for Bending Straightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bending straightening machines for long workpieces face accuracy limitations due to frictional forces between the workpiece and roller conveyors, which hinder elastic recovery and precision during the bending process.
Innovation Solution
A feed and removal device for bending straightening machines that employs height-adjustable detection devices with gripping heads to support and rotate workpieces, allowing for precise positioning and movement along the processing path, enabling efficient and accurate bending of workpieces of varying lengths by excluding horizontal conveyors and using non-positive gripping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a roller conveyor is used to transport and support the workpiece during bending straightening, then the workpiece can be easily moved and positioned, but frictional forces between the workpiece and roller conveyor hinder elastic recovery and reduce bending accuracy
Solution Approach 1:
The invention extracts the workpiece from continuous contact with the roller conveyor by using detection devices with gripping heads to lift and hold the workpiece at specific positions. This removes the harmful frictional contact while maintaining easy positioning through the gripping mechanism, resolving the contradiction between ease of operation and bending precision.
2Manufacturing precision
If detection devices with gripping heads are used to support and rotate the workpiece, then elastic recovery is improved and bending precision increases, but the device complexity increases due to additional gripping and rotation mechanisms
Solution Approach 1:
The detection devices are designed with multi-functionality, serving both as detection instruments and as gripping/rotation mechanisms. By combining these functions into single integrated components, the invention improves bending precision through controlled positioning and rotation while minimizing the increase in device complexity that would result from adding separate mechanisms.
3Adaptability or versatility
If the detection devices are height-adjustable and movable along the processing path, then the machine can handle workpieces of varying lengths and improve adaptability, but the device complexity and adjustment requirements increase
Solution Approach 1:
The detection devices are designed with dynamic capabilities, being height-adjustable and movable along the processing path. This allows the system to adapt to workpieces of varying lengths and positions. The dynamic adjustment mechanisms are integrated into the detection device structure, enabling versatility while controlling complexity through unified design rather than separate adjustment systems.

AI summary
The invention relates to a device for feeding long workpieces (W) into and removing same from a processing machine, such as a bending-straightening machine, in which the long workpiece (W) located in the processing positions defines a processing section (WP) and the long workpiece (W) is supported at both end regions thereof by a respective gripping arrangement (2A, 2B). In straight extension (EPA, EPB) of the processing section (WP), a horizontal conveying means (3) for the long workpiece (W) adjoins at least one head end (WPA, WPB) of the processing section (WP). At least one of the gripping arrangements (2A, 2B) has a gripper head (8A, 8B) for frictionally gripping an end (WA, WB) of the workpiece (W) conveyed by the horizontal conveying means and drive means for drawing the workpiece (W) to be straightened into the processing section (WP) and for pushing out the straightened workpiece onto the at least one horizontal conveying means by means of the gripper head.
