Drum-type shot blasting machine

Abstract

The invention discloses a drum-type shot blasting machine. The drum-type shot blasting machine comprises a shot blasting chamber, a shot blasting device, a spiral conveyor, a lifter, a separator, a shot supply device, a dust removal system and an electric control system. The shot blasting chamber comprises a chamber body; a long-strip-shaped opening is formed in the front side wall of the chamber body; the shot blasting device is fixedly installed at the upper inclined corner of the rear side of the chamber body; a drum, a drum support, a rotary speed reducer and a drum swing mechanism are installed in the chamber body; the drum support is rotationally installed in the chamber body; the drum is installed in the drum support; the rotary speed reducer is installed at the bottom of the drum support and connected with the drum so as to drive the drum to rotate; and the drum swing mechanism controls the drum to swing by different amplitudes. By the adoption of the drum-type shot blasting machine, the shot blasting strength can be effectively improved, the cleaning time of one shot blasting process is greatly shortened, the cleaning effect is achieved, and cost is reduced; and meanwhile, the drum-type shot blasting machine is simple in structure, batch feeding tasks can be completed, the damage to operators is reduced, the production efficiency is improved, and the requirement for semi-automatic production and machining is met.

Description

technical field [0001] The invention relates to the technical field of shot blasting machines, in particular to a drum type shot blasting machine. Background technique [0002] The shot blasting machine sends the steel shot to the high-speed rotating disc, and uses the centrifugal force to make the high-speed shot hit the surface of the part to achieve the purpose of smooth cleaning. In the prior art, there are many different models of shot blasting machines, for example, according to the structure of the casting carrier, they are divided into drum type, chain plate type, rotary table type, trolley type, squirrel cage type and hanging type shot blasting machine Etc., the drum type shot blasting machine is suitable for cleaning all kinds of castings, forgings and precision workpieces that are not afraid of collisions and scratches. It is an ideal equipment for cleaning residual sand and scale on the surface of workpieces in small heat treatment workshops. However, the tradit...

Problems solved by technology

However, the traditional drum type shot blasting machine also needs to manually feed the workpiece to be cleaned, which has problems such as high labor intensity, low work efficiency, and unsafe operation; at the same time, the drum type shot blasting machine in the prior art is performing the blast cleaning process. The fixed rotary shot blasting station is easy to sink to the bottom for some smaller workpieces to be cleaned. It is in the lower layer of the drum shot blasting and is not easy to be turned over. The cleaning effect is poor, which wastes the cost of projectile processing. The cleaning time is long and the cleaning efficiency is low. question
