Description
Technical Field
The invention relates to the field of steel pipe welding laser cleaning devices, in particular to laser cleaning equipment for processing welded joint steel pipes.
Background
With the development of technology, people pay more attention to the quality of life, and environmental protection consciousness is also stronger. The conventional cleaning methods, such as mechanical cleaning, chemical cleaning and ultrasonic cleaning, have failed to meet the needs of people, and people have begun to pursue new cleaning methods which are neither harmful to health nor pollute the environment, and thus laser cleaning machines have been developed.
The laser cleaning technology is a process of irradiating the surface of a workpiece with a high-energy laser beam to instantaneously evaporate or peel dirt, rust or coating on the surface, and effectively remove attachments or coating on the surface of a cleaning object at a high speed, thereby achieving cleaning. The laser cleaning is a novel high-efficiency environment-friendly cleaning technology, and is a novel technology based on the interaction effect of laser and substances. Unlike traditional mechanical cleaning, chemical cleaning and ultrasonic cleaning (wet cleaning process), it does not need any organic solvent of CFC class to destroy ozone layer, has no pollution, no noise, is harmless to human body and environment, is a "green" cleaning technology, and gradually replaces traditional cleaning process in numerous fields. The principle of laser rust removal is that, in short, the rust layer is broken by using the high-frequency vibration (1000 times per second) generated by the laser with the wavelength of 1064nm which is specially used for cleaning and is generated by a Nd-YAG solid laser; the rust layer is peeled off the surface of the base material by utilizing the instant high temperature generated by the laser, thereby achieving the aim of rust removal.
The laser cleaning can not damage the surface of the substrate, even can not change the physical characteristics of the substrate, and can really not damage the substrate. The laser rust removing device is characterized in that the laser rust removing device is a laser with certain peak power and single pulse energy, when the laser contacts with a working surface, the laser can be imagined as sequentially removing the laser with small energy balls, rust can absorb energy, and because the action time is short, the rust on the surface absorbs energy and instantaneously vaporizes, and cannot conduct heat downwards, the effect that the rust on the surface instantaneously disappears without damaging a workpiece is caused, the mirror for the laser is changed into linear laser, and the processing speed is relatively high.
The traditional laser cleaning equipment is handheld, and the metal surface such as rust, paint and the like is burnt out mainly through laser that the laser rifle head produced, uses metal reflection characteristic simultaneously, ensures that part itself does not damage. The principle of this laser cleaning machine is that when rust is subjected to high temperature, it instantaneously evaporates, and after plasma separation, the rust-removed portion is not damaged even if exposed to laser light due to high reflectivity of underlying metal to light, and thus this laser cleaning method is effective and safe, and can clean the corners of parts such as letters and bolts even perfectly. Therefore, whether or not rust is difficult to remove can be easily handled. As long as the light can reach, the rust is hidden.
However, the existing handheld laser cleaning equipment needs a worker to hold the laser gun head for operation, when the laser gun head is out of hand, laser generated by the laser gun head can possibly irradiate surrounding workers, and unpredictable potential safety hazards exist; when the welding line of the steel pipe is subjected to laser cleaning, a worker can only carry out laser cleaning treatment on the welding line outside the steel pipe, can not carry out laser cleaning operation on the welding line inside the steel pipe at the same time, the whole cleaning efficiency is required to be improved, and secondly, when the welding line inside the steel pipe is subjected to laser cleaning, the worker holds a laser gun head to carry out laser cleaning treatment on the inside of the steel pipe, so that the stability of the hand of the worker is extremely high, and the welding line of the deep area inside the steel pipe cannot be treated due to the limited length of the hand of the worker, so that obvious limitation exists, and in addition, the inside of the steel pipe cannot be completely observed by human eyes, so that when the laser cleaning is carried out on the inside of the steel pipe, the worker can often miss the steel pipe partial area, defective products cannot be effectively controlled, the follow-up detection of defective steel pipes is difficult, and the steel pipe with fine defects is very easy to leave a factory.
Therefore, it is very necessary to invent a laser cleaning device for processing welded steel pipes.
