Description

Technical Field

[0001] The utility model relates to the technical field of bent pipe installation, in particular to a bent pipe welding point grinding device. Background Art

[0002] A pipe elbow is a pipe with a curved shape. It is a commonly used pipe component, including metal and plastic types. It can be used to change the direction of the pipe and is currently widely used. During the installation of metal pipe elbows, the two ends of the pipe elbow are generally welded and fixed to straight pipes or other pipe elbows with different degrees of curvature to adapt to use in different environments, such as stair handrails. After the welding of the pipe elbow is completed, the weld points need to be polished to increase the aesthetics.

[0003] The existing methods of grinding bent pipes are: first, directly welding the bent pipes in the processing workshop, grinding the welding points with a grinder, and then transporting them to the construction site for integrated installation. This method has great limitations. The second method is to directly weld and grind the bent pipes at the construction site, but when grinding at the construction site, it is generally done manually with a grinding wheel, and the angle of the grinding disc needs to be repeatedly adjusted to ensure that the entire circle of the bent pipe is ground, which is rather troublesome. For this reason, we provide a device for grinding the welding points of bent pipes to solve the above problems. Utility Model Content
