Description

one

The invention relates to equipment for thermal cutting of metal and can be used for oxy-fuel cutting of parts in chemical and transport machinery. structure, shipbuilding and other industries of the industrial sector.

A caliper of a gas-cutting machine is known, which contains a driving swivel mechanism mounted on a bracket with the possibility of free movement, on the output 10 shaft of which a shaft with cutting torches and cam followers mounted on a bracket l are fixed.

This device does not provide the required quality of the initial section of the cut, due to the fact that the speed of movement of the butt end of the cutter when turning from the initial position to the position of the beginning of the cut varies according to a complex law, since with the same angular speed of the rod's lift the linear speed of the cutter face different in the area of about 30 mm

For the quality of the initial section of the cut, the pivot mechanism is equipped with a cogging sector mounted on a crank-25

not connected with the rod, while the axis of rotation of the sector is aligned with the axis of the copy rollers.

FIG. 1 shows a profile projection of the proposed device; in FIG. 2. frontal projection is shown; Fig. 3 shows a horizontal projection of the device; Fig, 4 shows the location of the cutter in the cutting process.

Claims (1)

The gas-cutting machine support consists of a slider 1, to which is attached a bracket 2 with a drive mechanism 3 (Fig. 1) on the output shaft 4 of which gear 5 is attached, hooked onto the teeth of sector 6. Sector 6 rests on axis 7. This axis is mounted in the hole of the bracket 8, rigidly fixed to the housing of the drive mechanism 3 and carries the roller 9. Dp rigidity of the structure to the sector 6 is attached to the sleeve 10 with the plate 11. The specified plate rests on the axis 12, also installed in the hole of the bracket 8 and the carrier roller 13, Through sleeve the rod 14, on which the cutters 1517 are mounted, is rigidly attached to it; All cutters can be installed on the R (hey height relative to the treated surface. In the slots of Sector 6, stops 18 and 19 are installed, and on the drive mechanism 3, the final destination 2O and 21 are placed. The drive mechanism 3 is equipped with a handle 22 with a latch 23 connected to an arm groove. The support of the gas-cutting machine works in the following way. When the drive is turned on (not shown), the slider 1 is lowered down to the canal of the rollers 9 and 13 from the surface being processed. In this case, the cutters 15-17, the entry shies in a shoot, for example, upright, are positioned above the edge of the surface to be treated, or at its specified points. Then implements. from the start-up and ignition of the mixture of the aa-oxygen mixture on the cutters 15, 16 and 17. Upon reaching a steady metal burning process, at. is driven into motion by a reduced gas cutting gas machine (not shown in the drawing) and at the same time the drive mechanism 3 is turned on to change the inclination of the cutters 15-17 relative to the treatment of my surface. The said drive mechanism is switched off when the pack {ph 18 is in contact, which sets the inclination angle of the cutters in the process of speed, cutting, with the final switch on 2O. This causes the gear to stop rotating. 5. In this case, the sector. 6 with a 14 barbell, the cutters 15, 16 and 17 will be set to the working position, i.e. at a given angle of attack to the front of the cut on the abutting surface. At the same time, the pressing of the stop 18 with the limit switch 2O and the cessation of movement of the drive mechanism 3 simultaneously, the system (not shown in the drawing) of a smooth increase in the speed of movement of the gas-cutting machine, which goes to a predetermined mode of operation, turns on. Since the sector 6 with parts and cutters 15-17 fixed on it, to achieve the required angle of inclination, turns around the axes 7 and 12 of the rollers 9 and 13 in contact with the Bend surface, the torches of the cutters practically develop around the line of intersection of the plane of these cutters with the treated surface. Point A {see FIG. 1) one of the points of the line. If it is necessary to switch from a longitudinal cut to the transverse body of the drive mechanism 3, which has a cylindrical glass (not shown in the drawing), which is installed in the bore of the bracket 2, rotate 90 together with the bracket 8 rigidly connected with it. Both positions of the device are secured by a stopper 23 The use of gas cutting machines with the proposed caliper is effective, as it allows to coordinate the automated process of starting the cut with the movement of the machine, to ensure an optimal mode of operation, as the established process ie cutting the same when plunging into the kick. The process is controlled from the model command-and-logic commands. This makes for a great deal of progress. The total technical and economic effect from the implementation of the invention may be expressed by the sum of 9OOOO rub. in year. Formula for gaining A caliper of a gas-cutting machine, containing a driving swivel mechanism mounted on a bracket with the possibility of free movement, a boom with cutting torches is fixed on the KOTOpoixi output wrap, and the copy rollers fixed on the bracket, in order to improve the quality of the initial section of the cut The swivel mechanism is equipped with a toothed sector mounted on a bracket and connected with a rod, while the axis of rotation of the sector is aligned with the axis of the cam rollers.
