A shot blasting device with double splitting wheels and double directional sleeves

Abstract

A shot blasting machine with double shot blasting wheels and double directional sleeves, including a main shaft, a casing, a shot inlet tube, a shot blasting wheel, a directional sleeve, an impeller body, and a shot blasting blade; Two, the inner shot wheel and the main shaft are fixed by bolts; the right end of the outer shot wheel and the inner connecting cylinder are connected by splines; the coaxial line of the inner directional sleeve is located between the inner shot wheel and the outer shot wheel Between; the left end of the inner directional sleeve is provided with a conical feeding pipe whose inner diameter gradually increases along the direction from feeding to discharging; It is equal-diameter docked with the shot pipe; the two orientation sleeves are relatively fixed and the shot blasting windows of the two are located on both sides of the axis and are set opposite to each other at 180 degrees. The shot blasting is more uniform, the shot blasting speed is faster, the shot blasting amount is increased, the efficiency is high, and the surface quality of the processed parts is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of shot blasting devices. Background technique [0002] The surface cleaning of castings is one of the important processes in the casting production process. Cleaning includes removing the sticky sand on the surface of the casting and the core of the inner cavity, removing the riser, drape, burr and metal oxide scale formed by heat treatment. In the past 30 years, it has been expanded to strengthen the surface of the workpiece, improve the service life of the workpiece, remove rust, remove scale and sand and core of castings, etc. [0003] Shot blasting machine is the most important general-purpose basic equipment in workpiece surface cleaning machinery and equipment. It is widely used in metal surface treatment such as derusting, polishing, and sand cleaning in industries such as ships, automobile engineering, and machinery manufacturing. The domestic and foreign markets have huge demand. [0004] The sho...
