Box-shaped workpiece shot peening moving rotary device and shot peening machine containing the same

Abstract

The invention discloses a device for moving and rotating a large box-shaped workpiece during shot blasting. The device comprises a supporting platform arranged on a track in a box-shaped shot-blasting chamber in a sliding manner, wherein the two ends of the supporting platform in the sliding direction are connected to a winding drum capable of bidirectionally rotating through cables, and the two cables are oppositely wound on the winding drum; a rolling path, a rolling ring which corresponds to the rolling path and is used for supporting a box-shaped workpiece to be processed, and a clamping power head used for driving the box-shaped workpiece to be processed to bidirectionally rotate are arranged on the supporting platform. A whole shot-blasting machine can be controlled in a manner of limiting the device in the shot-blasting chamber through travel switches. Through the device, the overall surface of the large box-shaped workpiece can be subjected to uniform shot blasting through once clamping, so that the production efficiency is high.

Description

technical field [0001] The invention relates to a box-shaped workpiece shot blasting moving and turning device and a shot blasting machine containing the device, belonging to the technical field of shot blasting machines. Background technique [0002] Shot peening is a surface strengthening process widely used in factories. It is a method of derusting the surface of metal parts before surface treatment after the metal parts leave the factory or complete a certain process. Due to the large dust during shot peening, the shot peening chamber of the shot peening equipment is generally a closed structure. In the previous equipment of this kind, most of the corresponding parts and workpieces were arranged together in a large steel cleaning chamber to prevent projectiles from splashing and dust from overflowing. Since there are multiple openings on the chamber, sealing is also a problem. [0003] Furthermore, when a box-shaped metal product is to be polished, the current shot blas...

Problems solved by technology

[0003] Furthermore, when a box-shaped metal product is to be polished, current shot blasting equipment causes blind spots in the projection towards the workpiece, so that it is not possible to completely polish the entire surface of the workpiece to be treated

Furthermore, the spray guns of the shot peening equipment in the prior art generally cannot realize the precise automatic control of the distance and angle. When processing parts with high requirements for shot peening strength and coverage, this type of shot blasting machine cannot meet the requirements.

In addition, for the processing of large curved surface parts, only straight-line movement trajectory can be used for shot peening, and the shot peening intensity and coverage will be greatly affected. In order to achieve uniform shot peening on the part surface, the parts need to be clamped many times. Processing efficiency is low
