Abstract

The invention relates to the technical field of strip steel welding, in particular to a single-sided double-point spot welding equipment. The equipment comprises an installing support, a welding mechanism and a transformer assembly, wherein the welding mechanism comprises a welding mechanism mounting base, a driving mechanism and a welding gun main body, the welding mechanism installing seat is arranged at the front end of the installing support in a floating mode, the driving mechanism and the welding gun main body are two sets, the driving mechanism is arranged on the welding mechanism mounting seat and drives the welding gun main body to move up and down, the transformer assembly is fixedly arranged on the installation support and is electrically connected with the welding gun main body. The equipment provided by the invention is high in anti-welding pressure reaction capacity and stable in electrode stress, the tension loss of the steel coil after spot welding can be reduced, and proper tension can be kept.

Description

technical field [0001] The invention relates to the technical field of strip steel welding, in particular to a single-side double-point spot welding equipment. Background technique [0002] Bell annealing after strip cold rolling is an important process in cold rolling production. In order to ensure the annealing quality, according to the process requirements, the steel coil in the annealing furnace needs to maintain an appropriate tension and the tension fluctuation range is controlled at 1% to 2%. If the tension of the steel coil is too high, in the state of high temperature annealing, the side atoms between the layers of the steel coil will interpenetrate and cause bonding; if the tension of the steel coil is too small, it will cause defects such as collapse and poor coil shape, so , the control of the tension of the steel coil becomes particularly important. According to the process characteristics of bell annealing, there is a temperature gradient in the radial directi...
