Wide lead belt production line continuous rolling synchronous control system

Abstract

The invention discloses a wide lead belt production line continuous rolling synchronous control system which comprises motors, a plurality of roughing mills and a finishing mill arranged behind the last roughing mill. The wide lead belt production line continuous rolling synchronous control system further comprises a programmable logic controller (PLC) control system and needle type microswitches, each motor controls one roughing mill or one finishing mill singly, all motors are connected to the PLC control system, the needle type microswitches are arranged on the roughing mills except the last roughing mill and used for detecting whether lead belt accumulation exists between the roughing mills, and results are fed back to the PLC control system. Through a buffer mechanism composed of an angle sensor, a supporting plate and a cylinder, rolling speed of the roughing mills or the finishing roll is controlled by matching with torque monitoring current so that tension of a lead belt can be controlled within an acceptable range accurately, accumulative error of the lead belt can be self-repaired and adjusted, and adjustment can be performed rapidly under different conditions.

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. [0002] Background technique [0003] 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 rat...

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.
