Description

Technical Field

[0001] The invention belongs to the technical field of flexible X-ray flaw detection, and in particular relates to a flexible X-ray flaw detection method. Background Art

[0002] Castings are industrial products formed by pouring high-temperature molten iron into a mold cavity and then cooling it. Due to the structural factors of the casting itself, there are some fixed heat nodes. During the cooling process, due to the different cooling speeds, the last cooled area cannot be effectively compensated for shrinkage, which easily leads to shrinkage holes and shrinkage defects, and there is a risk of fatigue fracture of the casting. Therefore, internal quality inspection of castings is a clear requirement of customers.

[0003] The intrinsic quality of castings - density. Currently, X-ray non-destructive testing is a commonly used method. The method generally used in the industry is a single-machine flaw detector. Manually take the workpiece and put it into the flaw detector, close the door, turn on the ray switch for detection, open the door, manually take out the workpiece, and continue the next cycle, or use a straight-line linear array scanning flaw detection method. Although this method is efficient, it has low resolution and is only suitable for flat castings with uniform thickness. For castings with complex structures, repeated detection is required, and the efficiency is greatly reduced, and it is difficult to achieve automation. There are also circular detection methods, but most of them cannot meet the various needs of customers, and the flaw detection method cannot meet the customized needs of customers (such as more convenient maintenance, qualified and defective marking functions for castings, one-time satisfaction of multi-angle detection needs, etc.), the overall efficiency is low, and the satisfaction is not high.

[0004] Therefore, it is necessary to provide a new flexible X-ray flaw detection method to solve the above technical problems. Summary of the invention

[0005] The technical problem solved by the present invention is to provide a flexible X-ray flaw detection method that can meet the needs of users for different roller heights, manual loading and unloading, robot automatic loading and unloading, convenient equipment maintenance, multi-angle one-time detection of complex structural parts, defective product marking function, and higher radiation safety protection requirements.

[0006] In order to solve the above technical problems, the flexible X-ray flaw detection method provided by the present invention comprises: X-ray flaw detection equipment and flaw detection method;

[0007] The X-ray flaw detection equipment includes: production line, loading station, unloading station, operating table, electric control cabinet, conveyor loop, detection station, lifting and transplanting, high pressure and oil cooling, maintenance door station, monitoring movement mechanism, protective lead room, robot, pallet, pallet roller line, protective lead room and radiation source;

[0008] The production line is provided with castings.

[0009] As a further solution of the present invention, the flaw detection method comprises the following steps:

[0010] S1. Arrange the loading and unloading stations together, so that only one person is needed to load and unload materials;

[0011] S2. Set the robot next to the production line and use the robot to automatically load and unload materials, so that the castings are transferred from the production line to the pallet on the pallet roller line, thereby meeting the user's automation needs.

[0012] As a further solution of the present invention, the height of the pallet roller line can be freely adjusted using the jacking mechanisms on both sides, thereby conveniently adapting to the height of the production line.

[0013] As a further solution of the present invention, the flaw detection method further comprises the following steps:

[0014] S3. The radiation source is arranged at the bottom of the equipment and connected by a snap-on method, which is convenient for disassembly and maintenance;

[0015] S4. The pallet adopts 360° rotation + C-arm ±45° swing for flaw detection, which can meet the multi-angle detection needs of complex castings at one time, greatly improving the flaw detection efficiency of complex castings.

[0016] As a further solution of the present invention, the protective lead room is provided with an ear room, so that an extra layer of protection is provided when the casting enters and exits the radiation lead room, which is safer.

[0017] As a further solution of the present invention, when the casting enters or leaves the ear room, the interlocking radiation source is turned off to improve safety.

[0018] As a further solution of the present invention, the radiation source is based on its penetrating property. When the radiation penetrates the object to be tested, defects or foreign matter inside the object will cause differences in the intensity of the penetrating radiation. By detecting the intensity of the radiation after penetration, it is converted into an image according to a certain method, and analyzed and evaluated to achieve the goal of non-destructive testing.
