Description

Technical Field

[0001] The utility model belongs to the technical field of burr treatment, and more specifically relates to a device for removing burrs from welded pipes. Background Art

[0002] When welding pipes, gap structures such as weld edges will be left on the outside of the weld. The burrs need to be polished off before normal use. If the burrs and other structures are not removed, they will pose a safety hazard and easily serve as a foothold for microorganisms. In the long run, this will cause corrosion of the pipeline and reduce its lifespan.

[0003] Based on the above, the deburring device currently used mainly fixes the pipe and rotates the pipe using a fixed grinding device to grind the pipe. It is inconvenient to install and cannot grind longer pipes or already installed pipes. Utility Model Content

[0004] In order to solve the above technical problems at least to a certain extent, the utility model provides a welded pipe burr removal device.

[0005] The purpose and effect of the weld pipe burr removal device of the utility model are achieved by the following specific technical means:

[0008] Furthermore, two groups of L-shaped frames are fixedly provided on both sides of the main frame, and cylinders are fixedly provided at the rear ends of the L-shaped frames, and the telescopic ends of the cylinders are fixedly connected to the control frame.

[0009] Furthermore, an air pump is fixedly installed at the bottom of the U-shaped bracket, and the air pump is connected to the four groups of cylinders through pipelines.

[0010] Furthermore, a rubber frame is fixedly provided on the front edge of the collector, and notches are provided in the middle of both ends of the rubber frame and brushes are installed thereon.

[0012] Furthermore, through holes are provided on the outside of the receiving tube and an interception net is fixedly provided thereon, and a non-return structure is integrally provided in the middle of the inside of the receiving tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] A positioning roller is set to provide a rotation function for grinding. The brush is aligned to the position outside the weld. The air pump is used to prop up and extend the cylinder, and the control frame is forced toward the main frame, thereby pushing the connecting rod to move. The connecting rod is pushed to merge the U-shaped wheel frames on both sides, and the positioning roller is used to position and clamp the pipe fitting, so that the device is rotated and positioned outside the pipe fitting. It can be flexibly adapted according to the installation characteristics of the pipeline and can be used to grind the installed pipeline.

[0015] A rubber frame is set to provide a closed protection function. The manually controlled hand lever pushes the collector close to the pipe fitting. The rubber frame fits outside the pipe and the brush fits outside the weld. Then the grinding motor is started to drive the grinding rod to rotate to grind the weld. The entire device is rotated outside the pipe to completely grind the weld, and the burrs polished off can be prevented from splashing.

[0016] A collecting tube is provided to collect burrs and waste chips. The side fan can be started to extract air. The outside air passes through the filter and enters the internal channel of the tilting frame, and then passes through the side fan and enters the collecting tube for interception and collection. The excess air is discharged through the interception net. BRIEF DESCRIPTION OF THE DRAWINGS
