Sand blasting equipment for preventing deformation of aluminum alloy thin workpiece

Abstract

The invention discloses sand blasting equipment for preventing deformation of an aluminum alloy thin workpiece. The sand blasting equipment comprises a work box, wherein a sand blasting cavity is formed in the work box, a lifting mechanism is arranged on the inner wall of the left side of the sand blasting cavity, a power conversion mechanism is arranged on the inner bottom wall of the sand blasting cavity, an iron sand cavity is formed in the inner top wall of the sand blasting cavity, a conveying cavity is formed in the inner top wall of the iron sand cavity, a conveying mechanism is arranged in the conveying mechanism, an iron sand discharge block which extends upward into the conveying cavity is fixedly arranged on the inner top wall of the iron sand cavity, and an iron sand dischargecavity which communicates the conveying cavity to the iron sand cavity is arranged in the iron sand discharge block in a penetrating manner. The sand blasting equipment prevents deformation of a thinwall of a workpiece when sand blasting treatment is carried out on the aluminum alloy workpiece and can recycle the iron sand after sand blasting automatically, so that production is facilitated. Thesand blasting equipment is suitable for being popularized in major machining plants.

Description

technical field [0001] The invention relates to the related field of metal materials, in particular to a sand blasting device for preventing deformation of thin aluminum alloy parts. Background technique [0002] Aluminum alloy materials have been widely used in aviation, medical equipment, rail transit and other industries, but there will be knife marks, scratches, flashes on the surface after machining, and oxidation spots generated during later storage and transportation. In order to understand and eliminate the above adverse factors, sand blasting has been widely used as a surface pretreatment process that is simple to operate, low in cost and can meet the surface requirements. [0003] At this stage, when the ordinary sandblasting method is used to process aluminum alloy thin-walled parts, the impact force of the sandblasting medium is likely to cause deformation of the aluminum alloy thin-walled parts, which affects the assembly of parts and cannot meet the design requ...
