Abstract

The invention relates to equipment for welding and surfacing, mainly to multi-core surfacing with adjustable surfacing pitch and lengths of weld beads. The purpose of the invention is to improve the quality of the cladding by continuously performing the process and adjusting the distance between adjacent weld beads. On the column 1 is pivotally mounted console 2 with frame 6, cam 3 and pantograph 4, the extreme hinge 5 of which is fixed to frame 6, and the other hinge 7 is movably fixed to frame 6 by means of a rack and pinion with rack 8 and gear 9. On the hinged console 13 a surfacing head with a torch 11, an oscillator 12 and a magnetic copy roller 10 coaxially mounted with the torch 11 is installed. The plates of copier 3 are made with slots. Roller 10 is moved along the surfaces of the plates and the slits, with continuous surfacing of the rollers with a step determined by the distance between the plates. This distance is adjusted by interchangeable patterns fixed between the plates of copier 3, as well as by moving the hinges of the pantograph 4 by means of a pinion gear. The device provides the surfacing of the rollers on the flat parts with a small allowance, their subsequent machining. 6 Il.

The invention relates to equipment for welding and surfacing, mainly to multi-core surfacing with adjustable surfacing pitch and lengths of weld beads.

The purpose of the invention is to improve the quality of the cladding by continuously performing the process and adjusting the distance between the adjacent weld beads.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. 1 in FIG. 3 is a view B in FIG. one; in fig. 4 - section bb in fig. 2; in fig. 5 is a view of FIG. 2; in fig. 6 is a section DD-D in FIG. 2

The device consists of a column 1, to which the rotary rigid console 2 is fastened. The copier consists of plates 3 fastened by pantograph bottom hinges 4. The lower hinge 5 of the pantograph 4 is rigidly connected to the frame 6. The lower hinge 7 of the pantograph 4 is connected to the gear shaft - which 8, which engages with the gear wheel 9 mounted on the frame 6. The magnetic roller 10 contacts the plate 3 of magnetic material and has a geometric center that coincides with the center of the welding torch 11. The burner 11 is connected to oscillatory 12, which to fixed to the articulated arm 13, Shar Nirni fixed to the column 1. The EMA is fused part 14 is fixedly mounted.

The copier plates 3 can slide along the guides 15 and are made in the form of a rectangle with a width equal to the diameter of the magnetic roller 10. At one end of the plate 3 at a distance of m + t + t / 2 a half-height slot is cut in the shape of a half-cylinder with a diameter equal to plate width t. Between the parts of the template 16, a removable insert 18 is fixed on the guide 17, fixed by a screw 19.

The device works as follows.

On the one side of the copier between the plates 3, the templates 16 are installed with the guide 17. If necessary, change the distance between the plates

3, interchangeable inserts 18 are inserted between the templates 16 and fixed to the screw 19 by sliding fit. The templates 16 and the inserts 18 on the guide 17 are fixed with slots. Move to

controlling 17 along plates 3, adjust the length of the weld beads.

The pantograph 4, the lower hinges of which are connected to the plates 3, presses the templates 16 to the plates 3 by means of a toothed rack 8 and gear 9. In order to maintain the same distance along the entire length between the plates 3, the latter are moved along the guides 15 in the slots of the frame 6.

When the diameter of the magnetic roller t, the width t of the plates of the copier and the distance between the center of the plates is 4t, the process of rolling the plates 3 by the magnetic roller 10 proceeds continuously and the distance between the centers of the weld rollers is maintained the same.

The welding torch 11 is installed in the corner of the part 14 so that when the torch oscillates perpendicular to the direction of deposition, the point of movement is at the edge of the part 14.

The size of the slit on the plates, equal to t + t / 2, is chosen so that the magnetic roller 10 in the process of rolling the copier does not touch the frame 6 and, having passed the plate 3 along its width, has moved to its other side.

By successive rolling of the plate 3, the magnetic roller 10 and the burner 11 below it, making transverse oscillations, weld the part 14. In the case when the diameter of the magnetic roller 10 is not equal to the width of the plate 3, it is necessary to change the distance between the centers of the plates with the pantograph 4 neither between the centers of the weld rollers is the same. At that, the arc and the supply of the surfacing material when the magnetic roller 10 is being run in the semi-cylindrical part of the plate 3 is turned off and the welding is carried out only when the magnetic Roller 10 along the rectilinear sides of the plates 3. Thus, flat rectangular surfaces are continuously deposited.

The device provides plasma-powder surfacing on flat parts of a thin uniform-height layer, reduces the machining allowances and improves the quality of the weld metal. At the same time, by adjusting the width of the deposited beads and the pitch of the deposition, they provide the desired height of the weld metal.

Formula of the Invention The device for surfacing, containing a stationary column, a horizontal console hinged on the column, consisting of links hingedly connected to each other, and a welding head placed on the console with a welding torch, characterized in that by continuously performing the process and adjusting the distance between adjacent weld rollers, the column is equipped with a rigid horizontal console with a frame, a multi-link pantograph that is hinged to it m and co
