Technical Field

The invention relates to a paint removing device, in particular to a special removing tool for bolt paint and a removing method for bolt paint.

Background

In real life, bolts are used in various industries, such as valve connections, flowmeter installation, etc., where bolts are required. In order to prevent the exposed bolt from being corroded, paint spraying, rust prevention and beautification treatment is often required to be carried out on the surface of the bolt. However, when some equipment is overhauled, the bolts are required to be removed, and paint on the threaded surfaces of the bolts can prevent the bolts from being removed, so that the paint on the threaded surfaces of the bolts needs to be removed first. The conventional method for removing the paint on the surface of the screw thread of the bolt is to firstly soften the paint surface by using a paint remover and then manually remove the paint. However, bolts fastened in places where some positions are restricted have a problem that the paint on the surface thereof is hardly removed. Moreover, for thicker painted bolts, multiple cleanups are required to remove paint from the threaded surface of the bolt, resulting in a long time required to disassemble a bolt. While this is a small problem, various industries are involved. Particularly, the maintenance tasks to be completed within a limited time are more required to be completed rapidly, and the bolt paint removal and disassembly are further required to be completed rapidly, so that the production can be restored on time.
