Large stainless steel container surface sand blasting equipment and automatic sand blasting production line

Abstract

The invention discloses large stainless steel container surface sand blasting equipment and an automatic sand blasting production line. The equipment comprises a lifting column and a lifting column servo driving module, a spray gun rotating mechanism is arranged at the lower end of the lifting column and comprises a driving device and a spray gun fixing device, and a plurality of spray guns with downward spray nozzles are arranged on the spray gun fixing device. The driving device drives the spray gun fixing device to rotate in the sand blasting direction, and the spray guns are connected with a sand conveying hose and a compressed air conveying hose. The sand blasting production line comprises sand blasting equipment, a sand blasting room body and a stainless steel container conveying mechanism. An opening is formed in the top of the sand blasting room body, a supporting framework is arranged at the opening, the lifting column servo driving module is arranged on the supporting framework, the stainless steel container conveying mechanism comprises a ground rail, a servo driving trolley and a servo driving roller frame, and a stainless steel container is placed on the servo driving roller frame. According to the sand blasting equipment and the production line, the color uniformity of the sand blasting surface of the stainless steel container and the uniformity of the sand blasting strength can be improved, and the sand blasting efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of workpiece sand blasting, and in particular relates to a large stainless steel container surface sand blasting equipment and an automatic sand blasting production line. Background technique [0002] Sand blasting equipment includes dry sand blasting equipment and wet sand blasting equipment. It uses high-pressure gas as power to accelerate the sand material to form a high-speed jet beam to spray the sand material onto the surface of the workpiece to be treated at high speed, so that the appearance of the outer surface of the workpiece or The shape changes, and under the impact and cutting action of the abrasive on the surface of the workpiece, the cleanliness and roughness of the workpiece surface are improved, thereby improving the mechanical properties of the workpiece surface, improving the fatigue resistance of the workpiece, and increasing the wear resistance of the workpiece. The adhesion between the...

Problems solved by technology

[0003] However, at present, manual sandblasting is still used for sandblasting on the surface of large stainless steel containers. Since one person can only hold one spray gun, the efficiency of sandblasting is low, the working environment is harsh, and manual sandblasting is labor-intensive; because the surface of large stainless steel containers is rotary There is a spherical or elliptical head at the end of the stainless steel container, a cylindrical surface or a conical surface in the middle, and a number of pipe joints, flanges and accessories of different sizes on the surface of the stainless steel container. The diameter of the stainless steel container varies from several From hundreds of millimeters to several thousand millimeters, the length of the stainless steel container ranges from a few meters to more than ten meters. Due to the complex shape of the stainless steel container, the shape changes greatly, and is limited by the complex structure of the workpiece. At present, there is no automatic wet sandblasting on the surface of large stainless steel containers. Technology
