Description

The invention relates to mechanical engineering and can be used for cutting long products into pieces at a given weight.

The purpose of the invention is to increase the accuracy of the cut-off volume of the product and increase productivity.

The drawing shows a diagram of the device.

The installation comprises a feed roller 1 with drive rollers, a device for determining the volume of the cut-off part 2 with a radioisotope device for continuously measuring the mass of a moving pipe with a detector 3, a calculator 4 and a pipe installation with drive supporting 15 rollers 5, 6 and pressure rollers 7, 8, displacement sensor 9, mass adjuster of the cut-off workpiece 10, computing device 11, adjustable control station 12, control circuit of the installation 13, cutting device 14.

Installation works as follows.

The pipes are fed to the feed roller 1, and moving along the roller table, they enter the device for determining the volume of the cut part 2, where the pipe is fixed in the installation unit by the drive support rollers 5, 6 and pressure rollers 7.8.

Information about the current mass measurements from the detector 3 of the radioisotope device through the calculator 4 is fed to the inputs of the computing device 11, to the other input of which pulsed signals from the displacement sensor 9 are supplied. The division value of the impulse of the sensor corresponds to the division value of a single measurement of the mass of the pipe.

The other inputs of the computing device 1 1 are supplied with the mass of the cut-off part of the pipe from the setter 10. In the computing device 11, the current mass G · is calculated according to the formula Gt == “2g i where is the unit measurement of the mass of the pipe, g / mm;

p - the number of pulses of the displacement sensor (the price of one pulse is 1 mm).

At the same time, the given mass G _{3 is} compared with the current C +. Upon reaching the equality bz == £ t s. of the computing device 11, a command is fed into the control circuit 13 to turn off the feed roller 1, and the command "Switch to reduced speed" is sent to the adjustable control station 12 of the drive rollers 5, 6.

After this, the rough is transported at reduced speed to the cutting device 14. In this case, the distance traveled by the pipe from the moment the pipe switches to a lower speed to the cutting line of the cutting device 14 is calculated in the computing device 11 (information is received from the displacement sensor 9). Since the distance from the measurement axis of the radioisotope device to the cutting device 14 is known (L _P = const), when L _{P is} reached, the computing device 11 sends a Stop command to the adjustable control station 12.

Moving the pipe at a reduced speed ensures accurate pipe stopping on the cutting line and flawless pipe cutting, which increases productivity, and calculating the current mass using a displacement sensor improves the accuracy of measuring the mass of the pipe.
