Embodiment Construction
[0028] The invention discloses a processing method of high-precision cold-rolled steel pipes, which includes the following steps:
[0029] (1) Pretreatment: Set the discharge mechanism 11 in the pickling tank 12, and inject pickling solution into the pickling tank 12, then install the cold-rolled steel coil on the discharge mechanism 11 and completely soak it in the pickling tank 12. in solution.
[0030] (2) Slitting process: the cold-rolled steel coil is input into the slitting machine 20. The slitting machine 20 includes a tailing detection device 21, a leveling mechanism 22, an electric eye intermediate detection device 23, and a circular knife wheel arranged in sequence. Assembly 24, length difference detection device 25 and coiling wheel assembly 26, the pickled cold-rolled steel coil passes through tailing detection device 21, leveling mechanism 22, electric eye intermediate detection device 23, round cutter wheel assembly 24. The length difference detection device 25 ...

The invention discloses a processing method for high-precision cold-rolled steel pipes. The processing method includes the following steps: 1) pretreatment: arranging a material unwinding mechanism in an acid pickling trough, filling the acid pickling trough with an acid pickling solution, and installing a cold-rolled steel coil on the material unwinding mechanism and completely soaking the cold-rolled steel coil in the acid pickling solution; 2) strip cutting treatment: feeding the cold-rolled steel coil into a strip cutting machine; 3) production and shaping of pipes: feeding steel strips into a pipe producing machine, which successively includes a cold-rolling mechanism, a shaping mechanism, a high-frequency welding mechanism, a shape finishing mechanism and an output work bench; and 4) test on finish products. Through the method, the cold-rolled steel pipes are produced in an automatic manner in the whole process. The method replaces a conventional method in which every step employs manual auxiliary mechanical devices for production, so that the method greatly increases automation degree, effectively increases production efficiency, reduces labor intensity and labor cost, and effectively ensures product precision.
Description
technical field [0001] The invention relates to the technology in the field of cold-rolled steel pipes, in particular to a processing method for high-precision cold-rolled steel pipes. Background technique [0002] Precision cold-rolled welded steel pipes for structural use are not only economical and practical, but also cost far less than seamless steel pipes, and can be used instead of seamless steel pipes in many occasions. At present, cold-rolled steel pipes have been widely used in automobiles, such as car seats, car dashboards, etc. [0003] At present, each process in the production of cold-rolled steel pipes is completed by manual auxiliary mechanical equipment, which has a low degree of automation, resulting in low production efficiency, labor-intensive, and increased labor costs. In addition, product accuracy cannot be guaranteed. Contents of the invention [0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main pur...
