Abstract

The invention provides a cold-rolled steel coil core welding method based on a joint robot. The cold-rolled steel coil core welding method comprises the following steps that firstly, a steel coil coreautomatic-welding device is mounted in a stepping beam area at an outlet for the procedure before batch annealing, wherein the steel coil core automatic-welding device mainly comprises the joint robot, a linear sliding table, a detection unit and a welding machine; secondly, motion interlocking is established between a stepping beam and the joint robot; thirdly, the height of a steel coil is detected; fourthly, the end face position of the steel coil is detected; and fifthly, welding motion teaching programming is conducted, specifically, at each coil welding position, a steel coil with the maximum width and the minimum diameter is used as a reference work condition for teaching programming for the joint robot, and in every two adjacent coil positions, the steel coil with the maximum width and the maximum diameter is used as a reference work condition for teaching programming for the joint robot. According to the cold-rolled steel coil core welding method based on the joint robot, manual welding work is replaced by the robot, so that automatic and unmanned welding of steel coil cores is achieved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for welding cores of cold-rolled steel coils based on joint robots. Background technique [0002] In the cold-rolled bell-type annealing process, the steel coil is hoisted by a vertical spreader. In order to prevent the core steel strip from being damaged and core-pulling failure caused by the loose core of the steel coil, the inner ring of the steel coil core must be welded and fixed. [0003] At present, manual arc welding or hand-held remote welding methods are generally used for coil core welding in domestic steel production lines. Manual arc welding, the labor intensity of operators is high, and personal health is endangered. With the use of handheld remote welding, the labor intensity and personal health hazards of the operator are alleviated, but the welding process still requires the participation of the operator.
