Description

Technical Field

[0001] The invention relates to the technical field of surface treatment of seamless steel pipe mandrels, in particular to a surface strengthening device for seamless steel pipe mandrels. Background Art

[0002] In the production process of seamless steel pipes, the mandrel plays an important role as a key component. However, due to long-term use, the mandrel is prone to wear, resulting in a decline in product quality. At present, there are some methods and technologies for strengthening the surface of the mandrel on the market, such as electroplating and thermal spraying. Although these methods can improve the wear resistance and corrosion resistance of the mandrel to a certain extent, there are still some shortcomings. For example, the thickness of the electroplating layer is uneven and easy to fall off; the thermal spraying process is complicated, the cost is high, and the coating adhesion is poor. Although various methods such as electroplating, thermal spraying, and laser quenching can improve the surface properties of the mandrel to varying degrees, there are still some common problems. First, the uneven coating thickness affects the overall performance of the mandrel; second, the process is complicated, the cost is high, and it is not suitable for large-scale production; finally, the environmental pollution is serious, which does not conform to the concept of modern industrial green production, and the efficiency is low when it is processed. Summary of the invention

[0003] In order to make up for the deficiencies of the prior art and solve at least one of the problems raised in the background technology, a surface strengthening device for a seamless steel tube mandrel is proposed.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a surface strengthening device for a seamless steel pipe mandrel, comprising a frame, a processing mechanism for processing the surface of the mandrel is fixedly installed on the upper end of the frame, and a fixing mechanism for assembling the mandrel is fixedly installed inside the frame below the processing mechanism, and the mandrel is located directly below the output end of the processing mechanism after being fixed, a dust removal mechanism for collecting dust is fixedly installed on the lower end of the frame, and a control host is fixedly installed on one side of the frame, the control host is electrically connected to the processing mechanism, the fixing mechanism and the dust removal mechanism, and when in use, the mandrel to be surface treated is placed on the fixing mechanism The fixing mechanism drives the core rod to rotate after being fixed, and the processing mechanism first performs sandblasting on the core rod to remove scale and impurities on the surface of the core rod, and at the same time increases the surface roughness to improve the effect of subsequent processing. During sandblasting, the rotation of the core rod and the lateral movement of the processing mechanism improve the uniformity of the surface treatment of the core rod. After the sandblasting is completed, the position of the core rod is adjusted by the fixing mechanism, and the surface of the core rod is cleaned, such as by spraying water or air, to improve the cleanliness of the surface of the core rod. During the surface treatment of the core rod, the dust removal mechanism is used to collect the dust generated during the treatment to avoid pollution and facilitate use.

[0005] Preferably, the processing mechanism includes a crossbeam, which is an inverted U-shaped structure and is fixedly installed on both sides of the upper end of the frame, a lifting electric telescopic rod is fixedly installed in the middle position of the crossbeam, a lifting frame is fixedly installed between the output ends of the lifting electric telescopic rod, and a first electric slide and a second electric slide are fixedly installed on both sides of the lower end of the lifting frame, respectively, a sandblasting gun is hinged at the output end of the first electric slide, and a cleaning nozzle is fixedly installed at the output end of the second electric slide, and when in use, the first electric slide and the second electric slide are used to facilitate the position of the sandblasting gun and the cleaning nozzle The position of the lifting frame can be reciprocated laterally to improve the uniformity of sandblasting and cleaning the surface of the core rod, and the height of the lifting frame can be adjusted conveniently through the lifting electric telescopic rod, which is not only convenient for adjusting the distance between the sandblasting gun and the cleaning nozzle when processing the core rod, but also avoids the influence of the processing mechanism when adjusting the position of the core rod. When adjusting, the lifting frame rises to a high position, which is convenient for adjusting the position of the core rod, so that the core rod is adjusted from the sandblasting gun position to the cleaning nozzle position, which is convenient for cleaning the surface of the core rod after sandblasting, and the cleaning nozzle sprays cleaning water or cleaning gas, which is convenient for use.

[0009] Preferably, a turntable is installed at the output end of the rotating motor and the output end of the multi-stage electric telescopic rod, and a clamp is installed on the turntable. The turntable and the output end of the rotating motor are fixedly connected, and the turntable and the output end of the multi-stage electric telescopic rod are rotatably connected. The clamp facilitates the installation of the mandrel between the turntables, and the rotation of the rotating motor drives the turntable to rotate, so that the mandrel itself rotates, thereby improving the uniformity during surface treatment.

[0011] Preferably, a guide hole is transversely opened at the upper end of the filter plate, and a slider is slidably engaged inside the guide hole, cleaning plates are fixedly installed at both ends of the slider, and a brush is fixedly installed at the lower end of the cleaning plate, one side of the brush is in contact with the surface of the filter plate, and the slider reciprocates inside the guide hole, so that the brush on the cleaning plate cleans the surface of the filter plate, so that the filtered particles or dust fall into the bottom of the filter plate with a V-shaped structure, and through the cleaning port, the collected particles or dust can be cleaned and collected for easy use.

Through the use of sand blasting, high-pressure gas carries fine sand particles to hit the surface of the core rod at high speed, removing oxide scale and impurities, while increasing surface roughness and improving the effect of subsequent treatment. Through the cooperation of the treatment mechanism and the fixed structure, the quality and uniformity of the core rod surface treatment are improved, the service life of the core rod is extended, and the maintenance frequency is reduced.

[0014] 2. The two groups of structures for fixing the core rods in the fixing mechanism make it easy to process two core rods at the same time, or to clean the other core rod while processing one core rod, thereby improving the processing efficiency.
