Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mechanical property testing of metal materials, and in particular, the present application relates to an observation and determination device and method of an automatic hot top forging test system. BACKGROUND

[0002] According to the black metallurgical industry standard YB / T 5293-2014 "Metal Material Top Forging Test Method", the top forging test is a process test method for testing the plastic deformation capacity of metal and detecting surface defects by applying axial pressure to the sample and compressing the sample according to the specified forging pressure ratio. The standard specifies that the sample size: the cross-sectional size of the hot top forging sample ranges from 5mm to 200mm, and the sample height is 1.5 to 2 times the cross-sectional size (allowable deviation ±5% h).

[0003] The existing manual operation process is as follows:

[0004] (1) Sample clamping: manually place the sample in the top forging test machine clamp, adjust the position to ensure the axis is aligned;

[0005] (2) Top forging execution: apply pressure to the specified forging pressure ratio (such as 1 / 3), and compress the sample to the target height;

[0006] (3) Crack detection: after top forging, manually transfer the sample to the observation platform, use pliers or manually rotate the sample, and visually check the 360° side cracks;

[0007] (4) Sample processing: manually transport the sample to the scrap area, and regularly clean the iron oxide skin on the platform.

[0008] The existing automatic process has the following limitations:

[0009] (1) Partially automated systems use mechanical hands and other automatic devices to only achieve mechanical control of the top forging pressure application process, but subsequent detection, marking, and cleaning still rely on manual labor;

[0010] (2) The sample observation needs to be laid on a large platform, and manual rotation is low in efficiency and prone to missing cracks (especially for large-sized samples);

[0011] (3) The accumulation of iron oxide skin needs to be cleaned frequently, and manual transportation of heavy samples (such as φ160mm) poses a safety hazard;

[0012] (4) The sample has no marking, and the test data cannot be associated with the physical sample, which can easily cause confusion in laboratory management.

[0013] In summary, the technical defects of the existing technology are summarized as follows:

[0014] (1) Low detection efficiency: manual observation requires checking each surface, and small cracks may be missed due to viewing angle limitations.

[0015] (2) Labor burden: sample handling (weight up to 50 kg), scale cleaning, sample crack observation, data recording all need manual operation, high labor intensity, long time occupation.

[0016] (3) Poor traceability: the sample has no unique identification, and the test results cannot be accurately associated with the process parameters, which violates the laboratory management requirements.

[0017] (4) Environmental hazards: hot upset forging sample high temperature residue (80℃-200℃), manual handling easy to cause burns; scale dust affects laboratory cleanliness.

Adopting rotating turntable 5 + photoelectric positioning technology: The turntable 5 is driven by servo motor 8 and the number of revolutions is precisely controlled by photoelectric sensor, achieving 360° detection of the specimen without blind spots, and improving the upset detection efficiency by 80%;

[0095] S5, robot 2 grabs the sample and transfers it to the waste cart;

[0096] S6, control the scraper rod to extend, drive the turntable 5 to rotate one circle and then stop;
