Abstract

The invention relates to rolling production and can be used in the manufacture of rolling rolls with a complex shape of a strand gauge. The aim of the invention is to improve the quality and reduce the complexity of manufacturing calibers. The device consists of a lathe 1 with a plate 2, a tool holder 3, a cutter 4, a copier 14 with a cylindrical axial bore, which additionally has radial grooves and grooves parallel to its axis. A copier 14 is fixed to the surface 11 of the neck 6 through the gaskets 12. The inner face of the gasket 12 is made less rough than the outer face. By means of the pin 17, the copier 14 is attached to the side face 10 of the barrel 8 of the roll 5. On the stove 2 there are two supports 18, supporting the shaft 19 with the levers 20. The roller 21 of the counterweight is pressed against the copier 14. 2 Il. with b cl

The invention relates to rolling production, in particular, to the manufacture of rolls with strands of gauges having a cross-sectional cross-section along the perimeter, and can be used in metallurgy and mechanical engineering in the manufacture of rolls with a complex shape of a strand gauge.

The aim of the invention is to improve the quality, reduce the complexity of manufacturing calibers.

FIG. 1 shows the proposed device, the cut; in fig. 2 - the same, side view.

The device (figure 2) consists of a lathe 1 with a plate 2, a tool holder (caliper) 3, a cutter 4, a roller 5, consists of a neck 6, three fa 7, a barrel 8. The roll barrel 8 has an outer radial surface 9 and an end surface 10 flat shape. The cam has radial grooves and grooves parallel to the axis of the copier. On the surface 11 of the neck 6, through the gaskets 12, the copier 14 is fixed with bolts 13 with a cylindrical axial bore. The inner edge 15 of the gasket 12 is less rough than the outer edge 16. By means of the pin 17, the copier 14 is fixed to the end face 10 of the barrel 8 of the roll 5. The copier 14 can be mounted on the neck 6 close to the side face 10 of the barrel B or at some distance 1, dependent on the radius g of the interface of the end face 10 of the barrel 8 and the outer surface 11 of the neck 6. The inner face 15 of the gasket 12 is made polished in order to prevent damage to the surface 11 of the neck 6 of the roll 5. The outer face 16 of the gasket 12 is made roughly rough withan increase in adhesion between the bolt 13 and the gasket 12. On the slab 2, there are two bearings 18 that support the shaft 19 with the arms 20. The roller 21 of the counterweight is pressed against the copy 14.

The device works as follows.

On the lathe 1 is set roll 5. On the outer surface

supporting shaft 19 with levers 20. Roller 21 pressed against counterweight to copier 14, moving on it by means of leverage 20 moves caliper 3 of machine 1 with cutter 4 fixed on it, which moves in one direction or another, thus giving shape to a caliber brook in accordance with the profile of copier 14. Due to the fact that the copier 14 is fastened with longitudinal pins 17, which ensures equality of inertia forces along the length of the pins, or is attached close to the face, the possibility of skewing in the system of levers, shaft and roller is significantly reduced The possibility of the copier 14 sliding along the perimeter of the neck 6 of the roll 5 and displacing along it is controlled. The device has a high rigidity due to the small lengths of the lever 20 and the shaft 19. In addition, the provision of the ability to rotate the copier relative to the axis makes it possible to make streams on a roll of a modular design, i.e. on the rings.

Example. A roll with a diameter of 550 mm is installed in the rolling mill workshop of the rolling mill of a metallurgical plant at a turning sta-fnok. On the neck of the roll is fixed copier 80 mm wide, maximum diameter of which is 500 mm. Between the inner surface of the copier and the neck of the roll laid pads, the inner edges of which are polished. The copier is fixed to the side face of the roll barrel with four pins with a diameter of 10 mm.

The use of the device significantly improves the accuracy of the manufacture of calibers, eliminates additional manual operations for fine-tuning the dimensions of the calibers to the desired accuracy, reduces the complexity of manufacturing and increases productivity. Providing the ability to manufacture gauges with high accuracy and a wide variety of shapes allows you to expand the range of highly efficient rolled sections.
