Automobile safety air bag steel pipe production line

Abstract

The invention relates to an automobile safety air bag steel pipe production line. A steel bar equal-length breaking machine adopts an automatic equal-length opening cutting method, and is used for breaking a steel bar; a straightening machine is additionally provided with a safety material delivery roll; a detection machine adopts a low-frequency eddy detection device and a high-frequency eddy detection device; the detection machine is provided with two discharging devices with structures that a discharging rod is inserted into an U-shaped groove hole in a sleeving way, a discharging arm and a rotary arm are fixedly arranged on each discharging rod, the other end of each rotary arm is hinged to a piston rod of a discharging air cylinder, a support roll is arranged on each discharging bracket, a receiving cloth belt bypasses a support rod and is wound on a receiving and discharging cloth roll, a roll shaft of each receiving and discharging cloth roll is fixedly connected with an output shaft of a gear reducer, an input shaft of each gear reducer is fixedly connected with a rotary shaft of a discharging motor, and the two discharging devices are symmetrically arranged at the two sides of a conveying roller. The automobile safety air bag steel pipe production line has the advantages that the steel bar equal-length breaking machine has a high automation degree; the steel pipe straightening machine adopts the rubber roll to deliver the material, so as to avoid the safety accidents; the detection mechanism adopts the semi-automatic charging method, so the manual labor intensity is decreased, and the surface and the inner wall of the steel pipe can be simultaneously detected.

Description

Technical field: [0001] The invention relates to the technical field of steel pipe production, in particular to a steel pipe production line for automobile safety airbags. Background technique: [0002] The production of steel pipe generally has to go through several steps of steel rod breaking, steel rod perforation, steel pipe pickling, steel pipe cold drawing, steel pipe straightening and flaw detection. The degree of automation is low, and the labor intensity is high. Its steel pipe straightening machine uses manual feeding, which has potential safety hazards. Its flaw detection mechanism can only detect flaws on the surface of the steel pipe, and the automation of loading and unloading is low. Invention content: [0003] The purpose of the present invention is to address the deficiencies in the prior art and provide a production line for automobile safety airbag steel pipes. Its steel rod breaking machine has a high degree of automation, and its steel pipe straighteni...
