Cutting-off process for high-quality Bundy tubes

Abstract

The invention discloses a cutting-off process for high-quality Bundy tubes. The cutting-off process comprises the following steps: firstly, correcting and guiding the Bundy tubes by using a correction wheel to enter a first conveying wheel set; conveying first sections of Bundy tubes with preset conveying lengths into a horizontal straightening device by the first conveying wheel set to carry out horizontal straightening; then, conveying the first sections of Bundy tubes with the preset conveying lengths into a vertical straightening device by a second conveying wheel set to carry out vertical straightening; next, conveying the first sections of Bundy tubes with the preset conveying lengths into a clamping and fixing device by a third conveying wheel set to carry out clamping and fixing; and finally, cutting off the first sections of clamped and fixed Bundy tubes by using a cutting-off device. By using the cutting-off process, the effect on straightening the Bundy tubes before cutting-off is good, wastes are prevented from being generated, meanwhile, the requirement for rapidly cutting off a mass of Bundy tubes when the mass of Bundy tubes with the same length are required is met, and the cutting efficiency of the Bundy tubes is effectively increased.

Description

technical field [0001] The invention relates to a high-quality Bondi tube cutting process, belonging to the technical field of mechanical processing. Background technique [0002] Bondi tube was invented by Detroit City Ford Motor Company Bondi in the early 1930s, so it is called Bondi tube. Bondi tube refers to a thin steel pipe with a diameter of 4.6-10.6, which is mainly used as a fluid guide for automobiles and refrigerators. The air guide tube and the Bondi tube are made of cold-rolled strip steel sheet coiling, welding and galvanizing. Most of the existing Bondi tubes are cut off by conventional chip cutters. Because the texture of the Bondi tube is relatively It is soft, so it is necessary to straighten the Bondi tube before cutting. However, most of the existing straightening methods use wheel straightening. The straightening effect is not good, which affects the later cutting and use of the Bondi tube, which is easy to produce Scrap, cutting Bondi tubes is ineffici...

Problems solved by technology

[0002] Bondi tube was invented by Bondi of Ford Motor Company in Detroit, USA in the early 1930s, so it is called Bondi tube. Bondy tube refers to a thin steel pipe with a diameter of 4.6-10.6. The air duct and the Bondi tube are made of cold-rolled strip steel coil, welded, and galvanized. Most of the existing Bondi tubes are cut by conventional chip cutters. Therefore, it is necessary to straighten the Bondi tube before cutting it. However, most of the existing straightening methods adopt the wheel-type straightening method. The straightening effect is not good, which affects the later cutting and use of the Bondi tube, and is prone to Scrap, inefficient cutting of Bundy tubes when large batches of equal length Bundy tubes are required
