Description

Technical Field

[0001] The utility model relates to the technical field of automatic detection equipment, in particular to an ultrasonic automatic detection equipment for forgings. Background Art

[0002] During the forging process, internal quality inspections are required. Currently, the vast majority of companies use a portable ultrasonic testing instrument, where qualified inspectors apply a coupling agent to the surface of roughly machined large forgings before manually scanning them. The inspectors observe the portable testing equipment's display throughout the process, determining the forging's internal quality based on the waveform displayed. A small number of companies producing smaller forgings use complete sets of automated testing equipment with accompanying water immersion tanks. These ultrasonic tests are performed by completely immersing the finished forgings in water, allowing the equipment to automatically determine the forging's internal quality.

[0003] In the prior art, inspectors use portable equipment to manually scan and inspect, which is affected by many factors such as the inspector's experience, hand feel, scanning speed, coupling effect, repeated coverage, and visual fatigue. The inspection results are greatly affected by human factors, and the inspection process is difficult to track and monitor. The inspection time of large forgings is long, and inspectors need to bend over for a long time and scan repeatedly, which is labor-intensive. During manual scanning, a handheld probe is scanned back and forth on the surface of the forging. Due to the inconsistency of different personnel's techniques and experience, it is easy to cause the reciprocating scans of local positions to not overlap during the inspection process, and there is a risk of missed inspections due to non-standard manual scanning. During manual scanning, inspectors need to use segmented repeated scanning to ensure full volume coverage during the inspection process. According to industry standards, the inspection process must not only ensure horizontal coverage, but also require a certain ratio of coverage between each scan segment. The efficiency of a single scan is low, and the inspection efficiency is low. The coupling method required for manual scanning is manual application of coupling agent. The uniformity and duration of the coupling agent application have a certain degree of influence on the inspection results.

[0004] Water immersion testing equipment is expensive to manufacture and requires significant investment. Furthermore, the equipment cannot be moved freely, which increases the handling costs for the production and testing of large forgings. Due to their large size, automated water immersion testing requires the construction of large immersion tanks, which must maintain water purity. Given the processing and testing environments of forgings, the cost of manufacturing and maintaining these tanks is high. Furthermore, the use of water immersion for large forgings is subject to significant limitations during transport and entry and exit of the tanks. Furthermore, the testing equipment is a precision instrument, which can easily lead to inaccurate test results due to contact with the forgings. Therefore, it is necessary to propose an automatic ultrasonic testing device for forgings to address these issues. Utility Model Content
