Abstract

The invention discloses a variable speed control method for cooling table output roller beds. The cooling table output roller beds are sequentially grouped when conveying towards cold shears, and a control circuit of each group of roller beds is provided with a controller used for controlling the operation speed of a roller bed motor. The principle is simple, the transform difficulty is low, the cost is low, the labor intensity is small, the control way for the cooling table output roller beds is changed through frequency conversion, grouping and PLC analog quantity control technology, the control performance for the cooling table output roller beds is improved, the noise in the working environment is lowered, energy conservation and environmental protection are achieved, the improved cooling table output roller beds are stable and reliable in operation, and production efficiency is high.

Description

technical field [0001] The invention relates to a speed-variable control method for an output roller table of a cooling bed, and belongs to the technical field of speed control of an output roller table of a cooling bed. Background technique [0002] The role of the cooling bed output roller table is to transport the rebar that has been cooled in the cooling bed to the cold shear for cutting to length, and then transport it to the collection area for collection. The stability of the output roller table affects the processing capacity of the cooling bed and cold shear, and directly affects the production rhythm. The entire technological process of the existing cooling bed output roller table is controlled by PLC, and the PLC receives the signal (forward or backward) from the console, controls the contactor to close and break, and achieves the control of starting and stopping the motor. For accurate braking, when the contactor is powered off during the parking process, the au...
