External threaded rod rust removal device

Abstract

The invention discloses an external threaded rod rust removal device. The external threaded rod rust removal device comprises a bottom plate, a clamping seat is fixedly mounted on the bottom plate, a rotating wheel is rotatably arranged on the clamping seat, multiple limiting clamping blocks are mounted on the inner wall of the rotating wheel, a rust removal barrel is fixedly mounted on the bottom plate, one end of the rust removal barrel is fixedly connected with a fixed barrel, one end of the fixed barrel is fixedly connected with the clamping seat, a rust removal cavity is formed in the rust removal barrel, multiple movable tables are movably arranged in the rust removal cavity, a connecting rod is fixed to one end of each movable table, a limiting plate is fixedly connected to one end of each connecting rod, and each limiting plate is in an arc shape and is elastic. Compared with the prior art, gas in extrusion balls is conveyed into a movable groove through connecting gas pipes, the gas pressure in expansion air bags can be increased through the gas, elastic plates deform, rotating plates are pushed to rotate outwards, cleaning barbs can abut against the inner wall of a thread, rust removal cleaning is conducted on the inner wall of the thread, and the rust removal effect on the interior of the thread is further enhanced.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to an external thread rod derusting device. Background technique [0002] Metal processing, referred to as metalworking, is a technology that processes metal materials into objects, parts, and components, including large parts such as bridges and ships, as well as tiny components of engines, jewelry, and watches. It is widely used in different fields such as science, industry, arts and crafts. [0003] Screws are often used for the connection between parts or equipment. The screw will rust after a long time of non-use. If you want to continue to use it, you need to derust the screw. The existing derusting methods are manual derusting with tools. Manually using tools to derust is not only time-consuming and laborious, but also the derusting is not clean, and the screw rods that are not derusted can not be used continuously. Therefore, we propose a derusting device for exter...

Problems solved by technology

[0003] Screws are often used for the connection between parts or equipment. The screw will rust after a long time of non-use. If it is to be used again, the screw must be derusted. The existing derusting methods are manual derusting with tools. Manually using tools to remove rust is not only time-consuming and laborious, but also rust removal is not clean, and the screw rods that are not rust-removed cannot continue to be used. Therefore, we propose an external threaded rod rust removal device to solve the above problems
