Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of cold-rolled precision steel pipes, and more specifically to a grinding device for the production of cold-rolled precision steel pipes. Background Art

[0002] Finished rolled tube is also called cold-rolled precision steel tube, which is a production process of seamless steel tube. Finished rolled tube is one of the higher-grade varieties among seamless steel tube products. It has the characteristics of high precision and surface finish requirements and is widely used in the fields of automobiles and motorcycles. When using cold-rolled precision steel tube to process parts, it is necessary to cut the cold-rolled precision steel tube according to the actual required part size. After cutting, the incision needs to be polished, which requires a grinding device for cold-rolled precision steel tube production.

[0003] The utility model patent with patent publication number CN209021773U discloses a steel pipe end face grinding machine. The setting of the slide seat and the slide frame allows the grinder to move horizontally and vertically relative to the steel pipe. The grinding head grinds the entire end of the steel pipe, which is suitable for steel pipes with poor end flatness. The cut steel pipe ends have high uniformity. The main problem is burrs. Although grinding the entire steel pipe end face can also remove burrs, it will grind off the steel pipe end, shorten the steel pipe size, and it takes a long time to grind the entire steel pipe end face. Therefore, it is necessary to design a steel pipe end grinding device.

[0004] In the prior art, in view of this, we propose a grinding device for the production of cold-rolled precision steel pipes. Utility Model Content
