Description
Technical Field
[0001] This utility model belongs to the technical field of pipe fitting production equipment, specifically disclosing a thin-walled round pipe fixed-length cutting device. Background Technology
[0002] Thin-walled tubes are typically made by piercing steel ingots or solid tube blanks to form a rough tube, which is then hot-rolled, cold-rolled, or cold-drawn. Thin-walled tubes hold an important position in my country's steel pipe industry. During the manufacturing process of thin-walled tubes, they usually need to be cut to obtain finished products of a predetermined length.
[0003] In the process of cutting thin-walled circular tubes to a fixed length, the operator first needs to measure and position the tube before cutting. However, when cutting a batch of small-diameter thin-walled circular tubes, the above process needs to be repeated continuously. Manual measurement, positioning, and cutting are inefficient, labor-intensive, and traditional cutting processes have low cutting accuracy, poor adaptability to different tube diameters, and long changeover and adjustment times. Ultimately, this results in low cutting efficiency, poor accuracy, insufficient cutting precision, high scrap rate, and wasted time, labor, and materials. Our company produces a titanium alloy thin-walled tube for use in special fields. Manual cutting is inefficient, and mature thin-walled tube cutting equipment on the market has low cutting efficiency. Furthermore, the cutting process can change the properties of raw materials due to factors such as high temperature.
