Blasting device

Abstract

Provided is a compact blasting device capable of automatically and continuously performing a blasting process without leaking sprayed material or dust from a blasting chamber. The blasting device comprises a blasting chamber having a wall for dividing an interior into at least two spaces, classification means for extracting reusable sprayed material from sprayed material and dust sprayed by a blasting nozzle installed in the blasting chamber, recovery means for drawing in and recovering non-reusable sprayed material and dust, and sprayed material replenishing means for replenishing sprayed material. The blasting chamber is provided with a turning means that has at least two holding members for holding a blasted object, and also has a columnar member for holding and moving the holding members. The holding members are disposed in a radial formation so that an end surface of one member is orthogonal to the columnar member.

Description

technical field [0001] This invention relates to the shot processing apparatus which can perform surface treatment continuously. Background technique [0002] Shot peening equipment is used in the field of surface treatment such as surface roughening, smooth finishing, surface roughness adjustment, chamfering, deburring, and etching of workpieces. For the shot blasting processing device, usually, after the processed object is put into the shot blasting processing chamber having a space communicated with the dust collecting device through the classification device and the pipeline, the shot or abrasive is sprayed toward the processed object by using the injection nozzle. Processing media such as cutting materials (hereinafter referred to as "blasting materials") are processed. The above-mentioned blasting material and the dust generated by the shot blasting process are transported out of the shot blasting processing room by the above-mentioned dust collecting device. Since ...

Problems solved by technology

However, as a method of preventing the above-mentioned blasting material or dust from blowing, it has been proposed to provide a partition wall that separates the workpieces from each other, or to provide a method of opening and closing doors that are opened and closed in parallel with the rotation of the above-mentioned turntable. However, in recent years, Recently, in shot blasting, the demand for more precise processing has increased, and the use of finer blasting materials for precise processing has increased.

In the case of using a fine blasting material, it is considered that the above-mentioned blowout prevention method is not sufficient.

In addition, it is considered that the blasting material and dust adhering to the workpiece and the above-mentioned turntable cannot be sufficiently removed, and the blasting material and dust leak to the outside of the shot blasting chamber by the rotation of the turntable.
