Description

6 1 g 6. d - ;; № / d; 13 The invention relates to equipment for cutting continuously moving profiles and pipes and can be used for cutting to dimensional lengths of profiles and pipes produced in rolling mills, roll forming machines and pipe welding mills. A device for cutting continuously moving length-dimensional blanks into segments of a desired length is known, containing two or more carriages, moved together, and also receiving relative mutual displacement with the help of a running screw and nuts installed on it, each of which is associated with one Noah from carriages. Each carriage carries a cutting tool mounted on it. This makes it possible to increase the range of relative movement of the carriages with the cutting tool. The proposed device is characterized in that the spindle screw is made without the possibility of rotation, and each nut is provided with an independent drive, informing it of rotation. In addition, in order to simplify and improve the installation of the carriages with the cutting tool at a distance that cuts the workpieces from cutting a given plate, the nuts are equipped with graduated discs associated with the rotational drives of the nuts using sensors. FIG. 1 shows a device diagram; in fig. 2 - node I on Ф: -1г. 1. The device comprises a frame 1, along the guides of which the drive platform 2 moves and the driven platform 3 connected to it. Each plate is equipped with a clamping device 4 and a cutting head 5 with independent drives. The movement of the molds is carried out using a rack-and-pinion gear transmission 6. On the drive platform 2, a mechanism 7 is installed giving a command to the segment when the specified length of the segment is reached. Platforms 2 and 3 are connected by means of a non-rotating screw 8 and mutually acting with it (see Fig. 2) installed in the gearboxes 9 nuts 10, each of which receives rotation from its drive. Nuts 10 are kinematically connected to command disks 11, which record the magnitude of the rotation angles of the nuts, and consequently, the movement of the platforms and interacting with the sensors 12, for example photodiodes. The counting result is transmitted to the totalizer. At the same time, a continuously moving pipe is cut into measured parts, which is carried out twice with the separation of two parts from the pipe. Upon reaching a certain (somewhat smaller than a predetermined length of the metering mechanism, it gives the command to accelerate the driven and associated slave platform. When the specified length is reached (and at this moment the platform and pipe move speeds are almost equal), the metering mechanism sends the second command to pick up the pipe the clamping devices and (the platforms move with the pipe as one unit) are made to cut the pipes. After the end of the cut, a command is given to expand the pipe and return to the initial position of the platforms (idle) The pipe cut by the head The mold 3 enters the roller conveyor, and the pipe cut off by the head of platform 2 is transported further through the opened clamp and the cutting head of platform 3, then enters the roller conveyor. The distance between the platforms (and hence the length of the pipes to be cut) is adjusted as follows. the idle time on the command from the control panel or software control system, such as a computer, changes the metering mechanism and drives the nuts 10 to approach (dilute) the platforms. The amount of movement of the platforms is counted by command disks interacting with the sensors 12 transmitting a signal to the summing device. Upon reaching a predetermined approach (dilution) value of the platform, a command is issued to disable the actuators of the nuts 10.

DEVICE FOR CUTTING CONTINUOUSLY MOVING DYNOMETRIC Billets 1. Device for cutting continuously moving lengthy workpieces, such as profiles and pipes, into segments of the required length, containing at least two carriages carrying cutting tools, moved together, and also receiving relative mutual movement by means of a lead screw nuts installed on it, each of which is associated with one of the carriages, characterized in that, in order to increase the range of relative movement of the carriages with a cutting tool, the lead screw is non-rotatable, and each nut is equipped with an independent drive, which informs it of rotation. 2. The device according to claim 1, characterized in that, in order to simplify and improve the accuracy of the installation of carriages with a cutting tool at a distance that ensures cutting of workpieces into segments of a given length, the nuts are equipped with graduated disks that interact with sensors that give a signal to the nut rotation drives .
