Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as Figure 1-2 As shown, in a sealed bottom plug according to the present invention, the top of the bottom plug body 1 is in the shape of an inverted cone, and the inverted cone angle α at the top of the bottom plug body 1 is 140 to 160 degrees; the bottom plug The body 1 is provided with an inner stepped surface 1-7 matching the pipe body 2; the bottom plug body 1 is made of plastic material. After the coating process is completed, since the bottom plug body 1 is made of plastic, it will shrink and deform after repeated baking in the oven. After the drum core coating and baking is completed, the bottom plug body 1 will be free from the product. In addition, because the top of the bottom plug body 1 is in the shape of an inverted cone, it is also very conducive to the smooth flow of the paint, and no unstable coating defects will be formed at the end of th...

Abstract

The invention relates to the technical field of coating industry and particularly relates to a sealed bottom plug, wherein the top of a bottom plug body is inversely conical, and the inverted cone angle at the top of the bottom plug body ranges from 140 degrees to 160 degrees; the bottom plug body is provided with an inner stepped surface matched with a pipe body. When the sealing type bottom plug is used, the port of the pipe body is plugged with the bottom plug body, so that coating is prevented from entering the pipe body, a procedure of internal erasing to the pipe body during the coating process can be eliminated, and product yield and production can be improved greatly. The sealing type bottom plug provided by the invention has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of the coating industry, in particular to a sealed bottom plug. Background technique [0002] As we all know, the existing coating process uses cylinders and air bags to grab aluminum tubes, making the inside of the aluminum tubes a closed space, and then immerses them in the paint for coating. During this process, because the air inside the tube will be compressed, the paint will still enter part of the aluminum tube. After a coating action is completed, a certain wiping action must be performed on the inside of the aluminum tube. This wiping action will have various degrees of adverse effects on the aluminum tube and the next coating. Therefore, how to prevent the paint from entering the interior of the aluminum tube has become a hot research topic in the industry. Contents of the invention [0003] The object of the present invention is to provide a sealed bottom plug with simple structure, reasonabl...
