Abstract
The invention relates to a method for protecting a non-spraying inner diameter surface of a sprayed part, which is characterized in that a protective tool made of steel plates with the thickness is selected to protect the non-spraying part of the inner diameter surface of the part, and a square protective tool is convenient to process, high in processing efficiency and low in consumption cost.
Description
Technical Field
The invention relates to a protection method, in particular to a method for protecting a non-spraying inner diameter surface of a part.
Background
The inner diameter surfaces of various parts need to be subjected to thermal spraying treatment to endow the surfaces with new characteristics, the inner diameter surfaces of the parts are usually subjected to local spraying, and non-spraying parts of the inner diameter surfaces need to be protected in the spraying process, so that the non-spraying parts are prevented from being polluted. The non-spraying position of the inner diameter surface is protected by a special tool or a special protective adhesive tape, the special tool is usually prepared by a metal material, and the protective adhesive tape is usually a fiber cloth adhesive tape. The method for protecting the non-spraying part of the inner diameter surface often has the following problems:
1. the special tool is poor in universality, each part needs to be prepared according to the non-spraying part of the inner diameter surface of the part, and the processing cost is high. Meanwhile, in the spraying process, the tool is easy to thermally deform due to poor heat dissipation conditions of the inner cavity, so that the service life of the tool is shortened;
2. the protective adhesive tape needs to be manually stuck to the non-spraying part of the inner diameter surface, and the required working hours are long. For a part lumen of "slim" construction, maneuverability is poor. Poor heat dissipation conditions in the cavity during the spraying process often lead to failure of the tape.
Disclosure of Invention
The invention aims to provide a protection method for a non-spraying inner diameter surface of a spraying part, which meets the following points:
1) the protection tool is convenient to prepare, good in universality and low in processing cost;
2) the service life of the tool cannot be shortened and the tool cannot be failed due to poor heat dissipation conditions of the inner cavity;
3) the protection tool is convenient and quick to mount and dismount, and production efficiency is effectively improved.
The technical solution of the invention is that a method for protecting the non-spraying inner diameter surface of a spraying part comprises the following steps:
(1) designing and processing a protection tool: designing and processing a protection tool according to a non-spraying part of the inner diameter surface of the part to be protected, wherein the protection tool is made of a steel plate with the thickness of 0.3-0.5mm, the plate is processed into a square shape, the length dimension of the square shape is the same as the axial length of the non-spraying part of the inner diameter surface of the part, and the width dimension of the square shape is more than 1.1 times of the radial perimeter of the inner diameter surface;
(2) installation: the plate is curled into a cylinder shape along the width direction and is placed in the inner cavity of the part, the two cylindrical ends of the plate are aligned with the boundary of the non-spraying part of the inner diameter surface, and the plate is tightly attached to the inner diameter surface by utilizing the elastic recovery action of the plate;
(3) spraying: spraying the parts;
(4) disassembling: and after the spraying is finished, taking out the protection tool.
The invention selects the steel plate with the thickness of 0.3-0.5mm to manufacture the protection tool to protect the non-spraying part of the inner diameter surface of the part, and the square protection tool is convenient to process, high in processing efficiency and low in consumption cost. The protection tool is good in universality, and one protection tool can be used for protecting various parts with similar sizes. Due to the fact that the structure is simple, after spraying, thermal deformation of the protective tool is easy to correct, and the service life is long. In addition, the protection tool is convenient and quick to mount and dismount, and the spraying production efficiency can be effectively improved.
Detailed Description
The non-spraying inner diameter surface protection method for the spraying part comprises the following steps:
(1) designing and processing a protection tool: designing and processing a protection tool according to a non-spraying part of the inner diameter surface of the part to be protected, wherein the protection tool is made of a steel plate with the thickness of 0.3-0.5mm, the plate is processed into a square shape, the length dimension of the square shape is the same as the axial length of the non-spraying part of the inner diameter surface of the part, and the width dimension of the square shape is more than 1.1 times of the radial perimeter of the inner diameter surface;
(2) installation: the plate is curled into a cylinder shape along the width direction and is placed in the inner cavity of the part, the two cylindrical ends of the plate are aligned with the boundary of the non-spraying part of the inner diameter surface, and the plate is tightly attached to the inner diameter surface by utilizing the elastic recovery action of the plate;
(3) spraying: spraying the parts;
(4) disassembling: and after the spraying is finished, taking out the protection tool.
Examples
Some parts are through hole structures, and the size of the inner diameter surface is phi 50 multiplied by 100. The upper end edge phi 50 multiplied by 20 of the inner diameter surface needs to be sprayed with the polyphenyl ester aluminum-silicon coating, and the other inner diameter surfaces do not need to be sprayed. The non-spraying part of the inner diameter surface is required to be free from pollution and damage. The specific implementation method comprises the following steps:
(1) designing and processing a protection tool: the protection tool material is 45# steel plate with the thickness of 0.3 mm. Processing the plate into a square shape by adopting a cutting processing mode, wherein the length dimension is 80, and the width dimension is 190;
(2) installation: the plate is curled into a cylinder shape along the width direction and is placed in the inner cavity of the part, the two cylindrical ends of the plate are aligned with the boundary of the non-spraying part of the inner diameter surface, and the plate is tightly attached to the inner diameter surface by utilizing the elastic recovery action of the plate;
(3) spraying: spraying a polyphenyl ester aluminum-silicon coating on the part;
(4) disassembling: and after the spraying is finished, taking out the protection tool.
The final result is: the non-spraying part of the inner diameter surface has good protection effect and no pollution and damage phenomena.
