Description
Technical Field
The invention relates to a metal product quality inspection device, in particular to an integrated machine for realizing automatic ultrasonic online detection and hardness online detection in the same area aiming at large-caliber steel products with the diameter of more than 400mm, belonging to the field of electromechanical integration application.
Background
With the development of material engineering and industrialization, more and more gases are being developed and applied in a renewable mode. Particularly, a new energy power supply with environmental protection benefits is gradually pursued, and in order to prolong the sustainability of energy released by stored gas under a unit volume, a storage mode of high-power compression is needed to be adopted for implementing inflation. Based on the requirement, the performance requirements on related steel products such as gas cylinders, buried steel pipes and the like are more and more strict, and respective strict detection specifications are provided in corresponding fields.
In pursuit of higher quality yield, the production process of large-caliber steel products is optimized in detail. The various process links from purification, proportioning, smelting, ingot forming, piercing, rolling, hot expanding to multiple cold drawing of metal raw materials are widely described in various technical data and patent documents disclosed in the prior art. Although the process optimization and improvement can improve the performance and the excellent rate of finished products, the hidden troubles of unbalanced wall thickness distribution, hidden damage and cracks of the products and the like caused by production environment or other factors cannot be avoided. If the performance quality detection is not strictly specified, the rated inflation pressure strength cannot be met after the pneumatic tire is put into industrial application. The rated inflation pressure is obtained by gas cylinder experiments or theoretical derivation with ideal performance or very close to the ideal performance, when the steel gas cylinder has dark injury and is forcibly inflated to reach the rated strength, the pressure of the gas stored in the steel gas cylinder towards the wall surface of the inner cavity of the gas cylinder is uniformly distributed, the wall surface of the inner cavity except the dark injury point naturally and effectively resists the pressure of expansion deformation, but the expansion deformation resistance of the wall surface of the inner cavity where the dark injury is located is lower than the average level of the wall surfaces of the peripheral inner cavities, so that pressure focusing is easily caused and the explosion of the cylinder body is possibly caused.
The existing method for carrying out nondestructive detection and hardness detection on a metal-bearing large-caliber steel gas cylinder and a steel pipe to judge whether a product is qualified or not is one of common nondestructive detection methods, ultrasonic detection is one of the common nondestructive detection methods, and the detection methods for both nondestructive detection and hardness detection relate to a manual or automatic implementation mode, but the two-aspect detection is usually carried out independently, and is carried out by dividing a field and arranging detection equipment, so that the equipment occupies a larger field, has high purchase cost and is more in labor investment. And for finished products with mass which is often measured in tons, the circulation among different detection devices also needs to consume higher energy consumption. At present, a technical solution for organically combining the two aspects of detection and realizing on-line automatic detection does not exist, and the mass production and quality inspection efficiency of related large-caliber steel products are greatly restricted.

For clear understanding of the design and functional implementation principles outlined above, what needs to be explained is: the all-in-one machine well develops the common characteristics and equipment requirements in the ultrasonic flaw detection and hardness detection aiming at the similar products and the opportunity that the two detection processes can be fused. The system is characterized in that a certain field space needs to be consumed, induction components such as a bearing machine tool, a detection probe facing the surface operation of a product and the like, a detection equipment reading or remote industrial control PC and preloaded detection software thereof are required, and the system also comprises a power subsystem which is arranged on the bearing machine and drives the product to rotate; the detection modules dedicated for the two processes are integrated and combined into the common features.
In view of further detailed features, as shown in fig. 5, the inspection operation cabinet 2 is provided with an operation table 22 and more than two display screens integrally connected based on an industrial control PC 21, wherein one display screen 23 receives signals of the industrial control PC to display results related to ultrasonic inspection, and the other display screen 24 receives signals of the industrial control PC to display results related to hardness inspection. By utilizing the industrial PC, the detection software of the two processes can be integrated, and the detection software synchronously runs under the two processes of the system and is respectively called for information man-machine interaction. The two display screens are selected to respectively present the detection results of the two aspects, so that on one hand, the phenomenon that the operation complexity is increased due to the display interface switching and the accidental pause phenomenon is avoided, on the other hand, the display resolution of the single-process detection result interface is favorably improved, and the result is clearly presented. Therefore, the industrial control PC or the detection software of the corresponding process has a software part for graphically displaying the detection result, so that the result displayed on the display screen is more intuitive and understandable.

Wherein the polishing assembly comprises a polishing cylinder and a polishing head integrally connected with the end part of the polishing cylinder, and the polishing assembly is provided with a purging spray head beside the polishing head. Unlike the output of the servo motor, the sanding assembly is preferably a pneumatic cylinder type drive in order to create an impact collision on the surface of the product. And different force application can be output corresponding to the polishing heads with different specifications.
