A control method for automatic adjustment of copper strip pickling line

Abstract

The invention discloses a novel automatic adjustment copper strip pickling line and a control method thereof, belonging to the field of strip production and processing. It includes an unwinding machine, a water brush machine, a passivation machine, a drying furnace and a winder. The first frequency converter is installed on the passivation machine; Between; both the first frequency converter and the second frequency converter are connected with the water brush machine. A vertical pressure roller is installed at the outlet of the water brush machine, and an arc-shaped detection plate is fixed on the end of the vertical pressure roller. The control method of the present invention uses the distance detection sensor to detect different heights of the vertical pressure rollers, generates signal sources of different sizes, and inputs them into the second frequency converter, and the second frequency converter fine-tunes the operating frequency through the signal source. The invention reduces the operating stations of the water brushing machine, saves labor costs, and can realize automatic control of the operation of the pickling line only by inputting a frequency conversion signal. The phenomenon of scratches between the loose and the ground.

Description

technical field [0001] The invention belongs to the field of strip production and processing, and more specifically relates to a control method for automatically adjusting a copper strip pickling line. Background technique [0002] Copper alloy flat wire is mainly used in the production of zippers for clothing and bags. At present, the traditional copper alloy flat wire forming equipment includes wire flattening machine, annealing furnace, cooling water pool, pickling tank and finished product drawing machine. Firstly, the copper alloy wire rod is transported to the wire rod machine, and the round wire rod is flattened into a thick flat wire to make a flat wire blank. Due to the large deformation of the wire rod during the flattening process, the flat wire becomes extremely hard and difficult. Subsequent processing, and the loss of subsequent processing equipment is serious, so it is necessary to soften the rough billet flat wire in an annealing furnace. The surface is sev...

AI Technical Summary

Problems solved by technology

In the whole process, the semi-finished product is composed of multiple processes of flattening, annealing, and pickling. The traditional pickling process is to transport the wire to the pickling tank for manual pickling, and the weight of the flat wire coil pickled by manual pickling is small. After pickling, it needs to be transported to the pickling tank for manual pickling, which consumes a lot of water, is labor-intensive, and takes time
