Description

Technical Field

[0001] The utility model specifically relates to the technical field of grinding devices, and specifically is a stainless steel square pipe edge grinding device. Background Technique

[0002] A stainless steel square pipe is a hollow long steel bar, called a square pipe because its cross-section is square. It is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsion resistance strengths are the same, it is lighter in weight, so it is also widely used in manufacturing mechanical parts and engineering structures.

[0003] Chinese Utility Model Publication No. CN 216126951 U discloses a stainless steel square pipe burr grinding device, including a bracket for transporting stainless steel square pipes. A first clamping part for clamping the stainless steel square pipe and driving it to move back and forth is arranged on the bracket. A fixed second clamping part is arranged at one end of the bracket, and a robotic arm is arranged on the side of the second clamping part. A grinding machine for burring the stainless steel square pipe is arranged on the robotic arm.

[0004] For the above-mentioned stainless steel square pipe burr grinding device, it is ground by a grinding machine. However, when grinding the edges of the square pipe, it is necessary to grind the edges of each plane one by one, and it needs to be adjusted many times, resulting in a reduction in efficiency. Therefore, we provide a stainless steel square pipe edge grinding device. By setting two horizontal grinding machines to grind the two sides of the stainless steel square pipe, and a vertical grinding machine to grind the upper part of the square pipe, it only needs to grind the bottom surface of the square pipe once to complete grinding and polishing, which is more convenient to use, improves work efficiency, and effectively makes up for the above problems.
