Description

The invention relates to the processing of metals by pressure and can be used in devices for cutting long products into blanks.

The purpose of the invention is to improve the reliability and performance of the process of cutting rolled „

The drawing shows a diagram of a rolling control system

The rental cutting control system contains a contactless induction phase shifter 1, the output of which is electrically connected to the analog signal-to-digital signal conversion device 2, the output of which is connected to the computing-command operations device 3, the second input of which is connected to the digital input device 4 , and the sensor 5 of the position of the butt cut end, which is equipped with a memory unit 6, electrically connected with the device 3 of the implementation of computational and command operations, one output of which th drive circuit connected to the control 7 8 9 scissors, and the other - with a drive control circuit 10 n feeder 12 rental 13, wherein the contactless phase shifter 1 rigidly connected to the driven sprocket shaft 14 of the feeder 12.

The system works as follows about

In the initial position, the rolling 13 is oriented in the longitudinal direction and fixed in the feed mechanism 12. When the feed mechanism 12 is turned on, the front end of the hire 13

passes through the divorced knives of the cutting mechanism of scissors 9 and is detected by the sensor 5 of the position of the butt cut, the signal from which is sent to the device 3 to perform computational and command operations through the memory block 6, the sensor 5 is simultaneously turned off the drive of the feeder and the scissors drive control circuit 7 for executing the programmed length of the calibration cut. In the memory block, a zero coordinate (the calibration cut line) is written, from which yshem vedets movement countdown rolled. With further advancement of the rental signal from a non-contact, ontact induction phase rotation

The body 1, whose phase shift is proportional to the angle of rotation, is converted into device 2 in the current linear displacement code. The length of the cut workpiece is set by the device 4 for inputting numerical data (linear displacement adjuster) 0

The device 3 performs a continuous comparison of the linear displacement master codes and the current displacement increment codes from the analog signal-to-digital code conversion device 2, when they are equal at the output of the device 3, the signal arrives at the feed control actuator circuit 10 for a shear drive control circuit 7 for performing the next cut of the rolled stock. The change in the size of the length of the workpiece is made by changing the digital code of the device 4 by the operator or from an external information management system.

The process is then repeated, with the sum of the zero coordinate and the lengths of the previous cut blanks taken as the reference coordinate of the increment of movement.
