Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.

[0034] Example:

[0035] In this embodiment, it is achieved through the joint action of several measures for rolling a steel bar 2# flying shear. During the implementation of the embodiment, continuous debugging is required to achieve the target effect. This embodiment adopts Siemens STEP software and 6RA7025 DC speed control device. Including the following measures:

[0036] A. If Figure 5 As shown, the thermal detection signal of the flying shear is changed from the previous level signal to the edge signal by using the rising edge command in the Siemens STEP software. The edge signal is also called a pulse signal. The difference between a pulse signal and a level signal is that the signal intercepted ...

Abstract

A method to improve the response speed of flying shears. It performs rising edge processing on the heat detection signal in the control software program corresponding to flying shears; uses the rising edge signal of the signal to lock the state of the signal, and uses the normally closed state of the signal after a delay To reset the locked state, realize signal filtering processing; adjust the transmission parameters of the DC speed control device, mainly adjust the PI parameters of its speed loop system and current loop system, and the speed loop system curve and current loop system curve must be guaranteed to be second-order Damping system; on the basis of the original program, a new calculation program block for the shear velocity of the flying shear is added, and the calculation program block processes the rising and falling edges of the signal of the proximity switch. Through the analysis and calculation of the system configuration, the present invention can properly optimize the control program of the flying shear to ensure the timeliness of its signal reception; cooperate with the control program to properly optimize the electric drive system to achieve the purpose of shortening the flying shear action cycle , thus improving the response speed of the flying shear.

Description

technical field [0001] The invention relates to the technical field of metallurgical rolling, in particular to a method for improving the response speed of flying shears. Background technique [0002] With the continuous improvement of bar production technology, the continuous and automatic level of bar production line is constantly improving. Flying shear is one of the important shearing equipment on bar production line, and its response speed will directly affect the production efficiency of the entire production line. . Due to the accelerated production pace of steel rolling flying shears, the phenomenon that the flying shears cannot respond when the head and tail are cut is completed, which leads to steel stacking accidents. Contents of the invention [0003] The invention provides a method for improving the response speed of flying shears, which is used for the purpose of shortening the action period of flying shears and improving the response speed of flying shears....
