Method and device for controlling cold-bending forming production line

Abstract

The invention relates to a method for controlling a cold-bending forming production line. The method includes an uncoiling and leveling step, a feeding and punching step and a sheet forming and fixed-length cutting step, and particularly includes writing various parameters; starting a leveler, a servo feeder and a sheet forming machine; lengthening sheets and enabling the sheets to droop; temporarily stopping the leveler from running if an uncoiling and feeding buffer position sensor outputs signals or the running time of the leveler is longer than T1; continuing judging whether the uncoiling and feeding buffer position sensor outputs the signals or not. The method and the device have the advantages that a CPU (central processing unit) automatically controls starting and stopping of various devices according to running conditions of the uncoiling and feeding buffer position sensor, a feeding and forming buffer position sensor, the leveler, the servo feeder and the sheet forming machine, so that the sheets cannot be excessively long or short, and the safety of motors and other mechanical mechanisms is protected; manual participation is reduced, and an automation degree is greatly improved.

Description

technical field [0001] The invention relates to a cold-bending production line, in particular to a control method and device for a cold-bending production line, which belongs to the technical field of electromechanical. Background technique [0002] At present, in the profile processing industry, the production of a profile is usually completed by multiple people working together, that is, one person loads and uncoils the material, and cuts it according to the required length; two to three people bend it, and each person bends one to two pieces on the bending machine. Bending, one person collects and packs the completed product, so to produce a profile, many people and multiple processes are required, the work efficiency is low, and the product uniformity is poor. Enterprises with conditions can simply combine the equipment in the above processes to form a production line, but the control methods of each equipment are independent, and each process also requires manual partic...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a control method for a cold roll forming production line in view of the above deficiencies, which overcomes the deficiencies of low production efficiency and poor product uniformity in the prior art. After adopting the control method of the present invention, the entire production line only Using one person to operate and one person to collect materials not only saves labor costs, but also greatly improves production efficiency by 3-6 times compared with traditional production methods, and at the same time, safety and product uniformity have been greatly improved.
