A Synchronous Control System for Continuous Rolling of Wide Lead Strip Production Line

Abstract

The invention discloses a continuous rolling synchronous control system for a wide lead strip production line, which includes motors, several rough rolling mills and a finishing mill arranged behind the last rough rolling mill. The continuous rolling synchronous control system for a wide lead strip production line also includes a PLC control system and needle microswitches, where each motor independently controls a roughing mill or a finishing mill, all motors are connected to the PLC control system, and the needle microswitches are set at the roughing mills except the last roughing mill On the rolling mill, it is used to detect the accumulation of lead-free strips between the roughing mills and feed back to the PLC control system. It can also be composed of an angle sensor, a supporting plate and an air cylinder through a buffer mechanism, and cooperate with monitoring the torque current to control the rolling speed of the rough rolling mill or the finishing mill, so as to accurately control the tension of the lead strip within an acceptable range, and can Self-healing and adjusting lead belt cumulative error to quickly adjust when dealing with different situations.

Description

technical field [0001] The invention relates to a synchronous control system for continuous rolling of lead strips, in particular to a synchronous control system for continuous rolling of wide lead strip production lines. Background technique [0002] The commonly used method for producing battery grids is the gravity casting method. This method has low production requirements, but the product grid grains are coarse, intergranular corrosion is prone to occur, and the production efficiency is also low. Nowadays, a relatively advanced extended stretching method is widely used to make lead blocks into grids of various specifications through continuous casting, strip cutting, continuous rolling, trimming, drying, winding and other processes through molten lead alloys. . Generally, 6 rough rolling motors and 1 finishing rolling motor are selected to complete the whole process, and the 6 rough rolling motors are combined with a single motor to match the output speed ratio of the ...

Problems solved by technology

However, this method requires high mechanical precision, and it is relatively rigid in the specific use process, and cannot be adjusted according to the actual situation. Once the product leaves the factory, the product is basically finalized, and it is relatively weak to deal with different situations.

Moreover, when dealing with grid products of different specifications, due to the mechanical cooperation and fixation between the rolling mills, it directly leads to the fixed and single product types.

And in actual use, there are certain fluctuations in working conditions, or changes in temperature, or changes in material formula, which makes the adjustment and adaptation of all the original technologies quite inconvenient and unintelligent.

In particular, the cumulative error of the lead tape caused by other subtle influences in the specific operation cannot be self-repaired and adjusted.
