Shot blasting machine

Abstract

The invention belongs to an abrasive jet machine tool or device and particularly discloses a shot blasting machine comprising a base, a first friction wheel, a second friction wheel, a motor and a roller and also comprising an electromagnet, a normally-opened trigger switch and a rack, wherein the second friction wheel is matched with the first friction wheel; the roller is provided with a steel shot; the surface of the roller is sleeved by the first friction wheel; the second friction wheel is arranged on the base and presses against the second friction wheel; the motor is connected with the second friction wheel through a conveying belt; the normally-opened trigger switch is electrically connected with the electromagnetic; and the electromagnet is fixedly arranged on the rack and is located above the steel shot. Compared with the traditional shot blasting machine, the shot blasting machine has the advantages that besides a way of driving the roller to rotate by the motor, a way of arranging the electromagnet is adopted, so that the rotating speed of the roller is kept stable, the motion of the steel shot is enhanced, and furthermore the shot blasting efficiency is effectively increased.

Description

technical field [0001] The invention belongs to abrasive jetting machine tools or devices, in particular to a shot blasting machine. Background technique [0002] After the production and processing of heat-treated parts, castings, forgings, castings, etc., they need to be cleaned to remove surface oxidation to achieve the effect of smoothness and dust removal. Now the factory generally uses artificial atmosphere to achieve the effect after processing, but this not only reduces the work efficiency, and cannot guarantee the quality of cleaning. [0003] The patent with the application number of 201010556820.0 discloses a drum type shot blasting machine, which includes a base, and a support is provided on the upper surface of the rear of the base. Hollow structure, the orifice of the body is placed vertically, the front of the body is movably connected with an end cover, a circle of bumps is provided on the outer circumference of the front and rear of the body, two support se...

Problems solved by technology

However, it mainly relies on the motor to drive the drum, and the rolling speed of the drum is relatively slow, which leads to poor shot blasting effect of the steel shot.

However, if you switch to a high-horsepower motor to forcibly accelerate the drum, although the efficiency can be improved to a certain extent, the increase in the speed of the drum will greatly increase the instability of the drum, which will easily cause the drum to slip heavily from the base
