Overhead Rail Hanger Hook Type Shot Blasting Machine

Overhead Rail Hanger Hook Type Shot Blasting Machine is suitable for surface cleaning or strengthening treatment of small and medium-sized castings and forgings in locomotive, motor, casting, construction, machine tool and other industries. Especially suitable for surface cleaning and shot blasting strengthening of castings and steel structures of many varieties and small batches to remove a small amount of sand core, sticky sand and scale on the surface of the workpiece; suitable for slender and thin-walled parts that are not suitable for collision Clean up.

    Overhead Rail Hanger Hook Type Shot Blasting Machine can be designed and manufactured according to the size of shot blasting workpiece. The workpiece is cleaned by shot blasting at one time, which can not only remove rust, welding slag, welding beans, oxide layer, impurities, dust, etc. on the surface of the workpiece, expose the true color of the metal, but also form a uniform surface on the polished surface, machining surface and other surfaces State and roughness. It can also eliminate the welding stress of the workpiece, improve the fatigue resistance of the workpiece, increase the adhesion of the paint film when the workpiece is sprayed, and finally achieve the purpose of improving the surface and internal quality of the entire structural member.

    The quality requirements for the shot blasting treatment on the surface of the steel workpiece: the projectile can reach the area coverage rate of 100%.

   It can complete the feeding, fast running to the front sealed room, frequency conversion speed regulation and slow speed shot blasting cleaning, fast running to the rear sealed room, and the hook automatically returns to the loading station through the track.

   The arrangement of the shot blasting chamber body and shot blasting device are determined by computer three-dimensional dynamic shot simulation.

    The electrical system is controlled by PLC.

    The hoist, separator, spiral, with pulse detection device can realize the automatic fault detection and alarm function.

   Adopt two-stage dust removal method to ensure the dust removal effect (settlement room + pulse back blowing bag type dust collector).

   The main wearing parts are made by new precision casting process to ensure long-term use of wearing parts.

　　Automotive Shot Blasting and Peening solutions

　　Sandblasting is to use compressed air to spray abrasive to the surface of workpiece at high speed. The purpose of sandblasting is to improve the appearance quality of workpiece surface by removing oxide layer and rust. Shot peening is to make the high-speed hard particles (generally steel particles) hit the surface of metal workpiece, in order to improve the fatigue strength of metal surface. Sand blasting and shot blasting are two different processes and different tools are used. However, both of them can be recycled.

　　The technology of shot blasting cleaning machine replaces the common cold and hot forming process to form large thin-walled aluminum parts, which can not only avoid the residual tensile stress on the surface of the parts, but also obtain the favorable compressive stress for the parts.

　　It should be noted that the service temperature of the parts treated by shot blasting machine should not be too high, otherwise the compressive stress will disappear automatically at high temperature, thus the expected effect will be lost. Their service temperature is determined by the material of the parts, which is about 260-290 ℃ for general steel parts and 170 ℃ for aluminum parts.
