Description

Technical Field

[0001] This utility model relates to the field of metal material processing quality inspection, specifically to a device for inspecting the flaring of the fusion joint of marine thin-walled aluminum alloy pipes. Background Technology

[0002] Thin-walled aluminum alloy tubing is widely used in rail transportation, aerospace, and other fields, and the quality of its fusion joint directly affects the mechanical properties and service safety of the components. Currently, traditional flaring tests for fusion joint quality inspection use conical molds, which can easily lead to uneven stress on multi-cavity tubing, causing misjudgments. Furthermore, this method only records the final fracture state and lacks crucial data such as force-displacement curves and deformation rates during the flaring process. Traditional fusion joint tests involve marking the fusion joint after macroscopic metallographic etching, then machining samples, and finally performing a compression test using an aluminum profile pressure testing machine. This process is complex and delays the inspection cycle. While non-destructive testing methods such as ultrasonic testing and X-rays are used to assess fusion joint quality, they require highly skilled operators, cannot directly reflect the mechanical properties of the fusion joint, have low testing efficiency, and are unsuitable for rapid sampling inspection on production lines.

[0003] To address the shortcomings of existing flaring joint inspection technologies for thin-walled aluminum alloy pipes, such as high inspection costs, long processing times, limited data acquisition, and limited applicability, there is an urgent need for a dedicated, efficient, accurate, and automated flaring joint inspection device. This device primarily addresses the following technical issues: First, it solves the pipe inspection compatibility problem by using a modular flaring fixture design and a wedge force conversion mechanism to achieve synchronous and precise force application to each flaring joint of irregularly shaped multi-cavity pipes, avoiding the uneven force distribution caused by traditional single-point loading. Second, it quantifies the inspection process data by integrating high-precision sensors to collect key parameters such as flaring force-displacement curves and deformation rates in real time, establishing a correlation between flaring joint quality and mechanical behavior, overcoming the limitation of traditional methods that can only determine the final fracture state. Finally, it optimizes inspection efficiency by employing hydraulic drive and automated control technology to reduce the inspection time per piece to less than one minute, meeting the rapid sampling inspection needs of production lines. Through standardized inspection procedures and an intelligent judgment system, it reduces reliance on operator experience, significantly improving the consistency of inspection results compared to manual judgment.

The lower end of the expanding tool slider 7 passes through the through groove, and the expanding tool cutter head 8 is connected to the lower end of the expanding tool slider 7. The expanding tool slider 7 converts the circular motion of the rotating disk 3 into the precise radial linear reciprocating motion of the expanding tool cutter head 8 along the expanding tool slide 6. The controller 9 is connected to the motor 2 and is used to control the speed of the motor 2.

The four flaring tool slides 6 are evenly distributed in a cross shape on the worktable 1-2, used to convert the circular motion of the rotating disk 3 into the radial linear reciprocating motion of the flaring tool slider 7 along the flaring tool slide 6. Through the coordinated design of the modular expanding die cutter head 8 and expanding die slide 6, synchronous and uniform force is applied to each fusion joint of multi-cavity pipes, solving the misjudgment problem caused by uneven force distribution in traditional conical dies, and improving inspection accuracy by more than 40%.

[0038] Step 2: Start-up detection: Controller 9 controls motor 2 to start, which drives the rotating disk 3 to rotate through connecting rod shaft 10, which is converted into linear motion of the expander slider 7 along the expander slide.

[0039] Step 3: Synchronous flaring: The flaring tool head 8 advances radially in a straight line along the flaring tool slide 6, applying a uniform radial force to the fusion joint of the aluminum alloy pipe to achieve standardized flaring.
