Introduce the shot blasting technology of mobile shot blasting machine

Dalian sand blasting and shot blasting processing, sand blasting is a way to clean the surface of parts by blowing out quartz sand at high speed with compressed air. It is also called sand blowing in the factory. It can not only remove rust, but also remove oil. It is very useful for coating. It is often used for rust removal on the surface of parts; Finish the surface of parts (this is the use of small wet sand blasting machine sold in the market. The sand is usually corundum and the medium is water); In steel construction, the use of high-strength bolts for connection is a relatively advanced method, because high-strength connection uses the friction between the joint surfaces to transfer force, so the quality requirements of the joint surface are very high. At this time, it is necessary to treat the joint surface with sand blasting.

The shot blasting technology of mobile shot blasting machine is one of the advanced processes for surface cleaning, strengthening, polishing and deburring of various mechanical parts in the world. The equipment is mainly composed of shot blasting device, wear-resistant rubber ring belt, winch, lifting, separator, feed conveying, dust remover and cleaning machinery. Generally, shot blasting is used for regular shapes. How many throwing heads are about the same height, which has high efficiency and small infection. Shot blasting and sand blasting are widely used in repair and shipbuilding industry. However, both shot blasting and sand blasting are the application of compressed air.

Of course, it is not shot blasting that requires a high-speed rotating impeller. In the repair and shipbuilding industry, shot blasting (small steel shot) is generally used in steel plate pretreatment (rust removal before coating); Sand blasting (mineral sand used in repair and shipbuilding) is mostly used in formed ships or sections. Its function is to remove the old paint and rust on the steel plate and paint it again. In the repair and shipbuilding industry, the important role of shot blasting and sand blasting is to increase the adhesion of steel plate coating paint. Whether the abrasive cyclone separator works normally.

In the process of sand blasting, the recovered abrasive and dust shall be effectively separated to the storage hopper. Before sand blasting, the dust removal system shall be checked to ensure that there is no dust overflow during cleaning (whether the pulse recoil device effectively removes the dust accumulated on the outer wall of the filter element during equipment operation). At the end of each shift, the scattered abrasive shall be cleaned manually, which is the cabin recovery room of the front and rear sections.

How to correctly set the processing route of WEDM: the part that is easy to process and has little impact on the performance of the workpiece should be selected for one knife of WEDM; Reasonably set up wire cutting processing route to save material loss; The cutting route needs to keep a certain distance from the end face of the workpiece; One side of the material that does not need to be processed and one end of the clamping shall be arranged on the route as far as possible.
