Inner wall trimming device for composite steel pipe

Abstract

The invention discloses an inner wall trimming device for a composite steel pipe. The inner wall trimming device comprises a workbench and a polishing device. A first clamp is fixedly installed at oneside of the workbench, and a second clamp is fixedly installed at one side of the first clamp. A driving device is fixedly installed at the other side of the workbench. A motor is arranged in an inner cavity of the driving device. A spindle of the motor is connected with a rotating shaft in a rotating mode. The polishing device is connected with the rotating shaft in a rotating mode and is further composed of a polishing rod and a liquid spraying pipe. The polishing rod and the liquid spraying pipe are fixedly connected through a fixing shaft. Polishing wheels are installed at the two ends ofthe polishing rod in a rotating mode, and one side of each polishing wheel is provided with a spring piece. Spraying nozzles are arranged at the two ends of the liquid spraying pipe, and one end of each spraying nozzle is provided with a valve. A connecting piece is fixedly installed at the lower end of the driving device. A ball screw is arranged on the workbench. A servo motor is arranged at one end of the ball screw. The inner wall trimming device for the composite steel pipe is simple in structure, convenient to use and practical.

Description

technical field [0001] The invention relates to the technical field of composite steel pipe production, in particular to an inner wall trimming device for composite steel pipes. Background technique [0002] There are many types of existing pipe inner wall trimming devices. Although the most commonly used equipment can produce honing and polishing marks in the same direction as the fluid flow, the polishing effect is poor, and it is easy to cause damage to the processed parts and damage to the trimming equipment. In addition, this type of device has a complex structure, high cost, and inconvenient operation. The process can only be completed well under the operation of professional workers in the prefabricated delivery room. If the operation is improper, it will affect the dressing effect, resulting in uneven wear marks and even Tube wall thickness is not uniform. Contents of the invention [0003] The purpose of the present invention is to provide a device for trimming t...
