Sand blasting device for motor train unit air compressor crankcase casting mold machining

Abstract

The invention proposes a sand blasting device for motor train unit air compressor crankcase casting mold machining. The sand blasting device comprises a sand blasting box, an object carrying plate for placing workpieces, a first sand blasting module, a second sand blasting module, a third sand blasting module, a first inductor, a second inductor, a third inductor and a controller; a separation plate is horizontally arranged in the sand blasting box; a conveying roller set for conveying the object carrying plate is arranged between a feed end and a discharge end of the separation plate; the first inductor is used for monitoring the in-place condition of the object carrying plate and sending monitored signals to the controller; the second inductor is used for detecting the in-place condition of the object carrying plate and sending monitored signals to the controller; the third inductor is used for detecting the in-place condition of the object carrying plate and sending monitored signals to the controller; and the first sand blasting module, the second sand blasting module and the third sand blasting module are mounted at the top end of the sand blasting box in sequence. The sand blasting device is universal in sand blasting and high in sand blasting quality, and improves the sand blasting efficiency of a motor train unit air compressor crankcase casting mold.

Description

technical field [0001] The invention relates to the technical field of sandblasting equipment, in particular to a sandblasting device for processing a casting mold for an air compressor crankcase of an EMU. Background technique [0002] Sandblasting machine is a kind of mechanical equipment that can spray abrasives onto the surface of workpieces by means of compressed air power. The abrasive is sprayed at high speed to the surface of the workpiece to be treated for impact grinding, so that the shape or shape of the outer surface of the workpiece surface changes. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness The degree improves the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, prolonging the durability of the coating film, and is also co...

AI Technical Summary

Problems solved by technology

During the sandblasting process of the existing EMU air compressor crankcase casting mold sandblasting machine, there will be incomplete sandblasting on the details, resulting in low sandblasting quality, increasing the chance of rework, and low work efficiency
