Abstract

Usage: in the processing of metals, pressure in various branches of engineering. SUMMARY OF THE INVENTION: The shape of the bottom is defined by the translational movement of the workpiece and its position relative to the forming rollers. The surface of the drive roller is formed by conical and cylindrical surfaces mating by means of a toroidal surface. The surface of the driven roller has adjacent conical and toroidal sections. The radii of the toroidal surfaces of both rollers are equal. 1 C.p. f-ls, 4 ill.

Description

The invention relates to the processing of metals by pressure and can be used in the chemical industry, agricultural and other engineering industries.

It is an object of the invention to improve the quality of the bottoms by employing rolling by profiled rollers.

 In FIG. 1 shows a device for manufacturing conical bottoms; in FIG. 2 - lower roller; in FIG. 3 - top roller; in FIG. 4 - conical bottom.

The device for producing conical bottoms comprises a base 1 on which a drive 2 is mounted, which drives the lower roller 3. The kinematic diagram of the lower roller drive is shown in FIG. 1. On the base 1, a rectangular box-shaped frame 4 is installed, in which a lower roller 3 is mounted (the fastening device of the lower roller in Fig. Not shown) and the upper roller 5, which is made with the possibility of vertical movement (device for moving the upper roller in FIG. . not shown). The caliper 6 is mounted on a table 7 with the possibility of reciprocating movement using a hydraulic cylinder 8, the cylinder of which is attached to the rack 9, and the rod to the body 10.

The table 7 is installed and fixed on the base 1 and in the frame 4. On the support b, a workpiece mounting unit is installed, consisting of a housing 10. On which the glass 11 is rotated, the position of the glass relative to the housing is fixed by nut 12, In the glass 11, finger 13 is mounted on ball bearings rotatable around its axis. By means of washers 14 and 15, a conical bottom 16 is fixed on the finger 13, 17 — a sheet of blank with a central hole is round, not installed on the finger 13 at the initial moment of rolling. In FIG. 2 shows the lower roller, where R is the radius

rounding at the junction of two surfaces of the cylindrical and conical, and - the angle of the conical surface of the lower roller. In FIG. 3 shows the upper roller, where R is the radius of the toroidal surface of the upper roller, and is the angle of the conical part of the roller. In FIG. 4 shows a conical bottom, an a-angle section at the apex of the cone.

The device operates as follows. ;

The workpiece 17 is installed on the finger 13

and secured with washers 14, 15 and a nut (not shown in FIG.).

In this case, the upper roller 5 is lifted up by the upper roller moving device (the upper roller moving device is not shown in Fig.). Next, the drive 2 is turned on, as a result of which the lower roller 3 comes into rotation, after which the upper roller 5 is lowered until it contacts the workpiece 17, the workpiece 17 comes into rotational motion. By lowering the upper roller 5, the required thinning of the workpiece 17 is achieved. By turning on the hydraulic cylinder 8, the workpiece mounted and secured to the support 6 through the workpiece holding device, consisting of elements 1.0-15. they are moved parallel to the axis of rotation of the upper 5 and lower 3 rollers, and the conical bottom 16 is obtained by rolling the rollers with a predetermined angle at the apex of the cone.
