Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring devices for elongated rolling stock are inefficient and unreliable, particularly when using hammers or knife arrangements, which often result in unsatisfactory deburring of end faces.
Innovation Solution
A deburring device with a height adjustment mechanism and detection systems to precisely control a swing arm with a knife arrangement, allowing for accurate removal of combustion beards by adjusting the height and angular position of the cutting edge relative to the rolling stock's end faces, using a control device connected to location and height detection devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hammers are used to remove burrs, then the deburring process is simple, but the deburring quality is inaccurate and inefficient
Solution Approach 1:
The patent replaces the traditional hammer-based mechanical impact system with a knife arrangement that uses controlled mechanical cutting action. The knife arrangement is guided by a swing arm mechanism to precisely remove burrs from end faces, transforming the deburring process from impact-based to cutting-based, thereby improving accuracy while maintaining mechanical simplicity
Solution Approach 2:
The patent introduces a dynamic swing arm mechanism that can pivot to adjust the position and angle of the knife arrangement relative to the rolling stock. This dynamic adjustment capability allows the knife to optimally engage with the end faces at different positions, improving deburring precision while adapting to variations in rolling stock dimensions
2Manufacturing precision
If a knife arrangement is used for shearing off burrs, then deburring precision improves, but reliability deteriorates due to unsatisfactory results and mechanical stress during continuous use
Solution Approach 1:
The swing arm mechanism provides dynamic positioning capability, allowing the knife arrangement to pivot and adjust its angle of attack on the burrs. This dynamic adjustment reduces mechanical stress by optimizing the cutting angle, preventing excessive force application, and thereby improving reliability during continuous operation while maintaining precision
Solution Approach 2:
The patent changes the operational parameters of the knife arrangement by introducing angular adjustment through the swing arm mechanism. By varying the angle and position parameters of the knife relative to the rolling stock, the system achieves effective burr removal with reduced mechanical stress, enhancing both precision and reliability
3Manufacturing precision
If height adjustment device and detection systems are added, then deburring precision improves, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where detection devices monitor the position and dimensions of the rolling stock, and this information is used by the control device to automatically adjust the height and angle of the knife arrangement via the swing arm mechanism. This closed-loop feedback system achieves high precision while automating the adjustment process, reducing the need for complex manual intervention
4Adaptability or versatility
If the swing arm pivots to reach end faces at different positions, then adaptability improves, but mechanical stress on the pivoting device increases
Solution Approach 1:
The swing arm mechanism enables dynamic adaptation to different end face positions through controlled pivoting. The dynamic nature of the swing arm allows it to smoothly transition between positions, distributing mechanical stress over the pivoting motion rather than requiring excessive force at fixed positions, thereby achieving adaptability while managing mechanical stress

AI summary
An elongated rolled stock (3) has a front and a rear end face (4, 5) and a burn mark (6, 7) on each of its end faces (4, 5). A de-bearding device includes a transport device by means of which the rolled stock (3) is conveyed at a transport speed (v) in a transport direction (x). A swing arm (8), a pivoting device (9), and a height adjustment device (10) are arranged below the transport device. The swing arm (8) can be pivoted by means of the pivoting device (9) about a horizontal pivot axis (12) arranged at a lower end of the swing arm (8) and orthogonal to the transport direction (x). The swing arm (8) has a knife arrangement (13) at an upper end facing the transport device, by means of which the burn marks (6, 7) present on the end faces (4, 5) can be removed from the rolled stock (3).The height adjustment device (10) allows the cutting unit to be set to a height that the knife assembly (13) reaches when the swing arm (8) pivots about the pivot axis (12). The beard removal device has a position detection device (15) and a height detection device (18), by means of which the position of each end face (4, 5) in the transport direction (x) and the height of an underside (17) of the rolled material (3) in the area of the respective end face (4, 5) can be detected at each detection time. A control unit (14) of the beard removal device is connected to the position detection device (15) and the height detection device (18) via data transmission to receive the respective detected position and height, and is connected to the pivoting device (9) and the height adjustment device (10) via control transmission to issue control signals.
