Surface paint spraying method for U-shaped curve galvanized pipe

Abstract

The invention relates to the field of building material surface paint spraying treatment, and particularly relates to a surface paint spraying method for a U-shaped curve galvanized pipe. An operation machine tool is provided. The surface paint spraying method is characterized in that the operation machine tool is in a U shape, and a gear movement rail is arranged in the middle of the operation machine tool in the horizontal direction and used for limiting movement of an inner gear; supporting frames are arranged at the four corners of the lower portion of the operation machine tool, and a main motor is fixedly arranged on the inner wall of each supporting frame; a paint spraying system is included and comprises an execution ring, a hydraulic sleeve is fixedly arranged on one side of the outer ring of the execution ring, a special U-shaped hydraulic rod is arranged in the hydraulic sleeve, the middle of the special U-shaped hydraulic rod is sleeved with a horizontal gear, the horizontal gear is arranged in the gear movement rail, and therefore the machine tool can spray paint to the turning position of the U-shaped galvanized pipe; before paint spraying, surface cleaning is conducted on the paint spraying target galvanized pipe at a time, the paint hanging rate is increased, and cost is saved; and meanwhile, due to the special arrangement of the machine tool, the length of the paint spraying system can be changed, and therefore the paint spraying requirement of U-shaped galvanized pipes with different turning radiuses is met.

Description

technical field [0001] The invention belongs to the field of paint spraying treatment on the surface of building materials, in particular to a surface paint spraying method for U-shaped curved galvanized pipes. Background technique [0002] As an important building material, galvanized pipe has the advantages of durability, high reliability, and strong coating toughness. However, at the same time, the zinc layer of galvanized pipe is an electroplated layer, and the coating and steel pipe are independently layered, so it is easy to fall off, so it is corrosion-resistant If the corrosion resistance is poor, it needs to be painted before use to improve its corrosion resistance. [0003] At present, the common painting of galvanized pipes is mainly manual painting and automatic straight pipe painting. Manual painting is prone to uneven paint surface, while automatic straight pipe painting is convenient and efficient, but it encounters U-shaped bend pipes. If it cannot be used, ...

[0002] As an important building material, galvanized pipe has the advantages of durability, high reliability, and strong coating toughness. However, at the same time, the zinc layer of galvanized pipe is an electroplated layer, and the coating and steel pipe are independently layered, so it is easy to fall off, so it is corrosion-resistant Poor corrosion resistance, it needs to be painted before use to improve its corrosion resistance

[0003] At present, the common painting of galvanized pipes is mainly manual painting and automatic straight pipe painting. Manual painting is prone to uneven paint surface, while automatic straight pipe painting is convenient and efficient, but it encounters U-shaped bend pipes. Can't be used, can only be painted manually
