Abstract

The invention relates to the processing of metals by pressure, and m. used in devices for volumetric spherical strapping of parts. The goal is to expand the technological capabilities of a spherical device. The carrier (B) 7 of the device with a spherical bearing surface is rotated by the rotation of a gear wheel, in the eccentric hole about the vertical axis of the device of which pin B 7 is located. The axis B 7 has a constant angle of inclination relative to the vertical axis of the device. The tool used for die forgings may be reset relative to the axis of the carrier. The reinstallation is carried out by using an axisymmetric tool holder (I) 16 installed and fixed in a cavity formed at the end B 7 by intersection of a spherical surface whose center is at the center of the spherical support surface B 7 with a plane inclined to the end B 7. And 16 also has an end that is angled at the angle m, and the angle of inclination of end And 16 is equal to the angle of inclination of the flat surface of cavity B 7. The tool holder has a flange with a spherical side surface in contact with the sphere nical surface of a cavity formed in an end face of the carrier. When C 7 of the rolling motion is communicated, tool 17 will deform the workpiece 13. 1 Cp f-ly, 2 ill. and

I The invention relates to the processing of metals by pressure and can be used in devices for volumetric spherical forming of parts.

The purpose of the invention is to expand the technological capabilities of the sphere-moving device.

FIG. Figure 1 shows schematically a tool holder with a vertical axis; in fig. 2 is the same, the position is coaxially with the axis of the carrier for conducting spho-mobile punching.

 On the frame 1 in the direction: there are 2 of them installed with the possibility of Bertizno | - about moving the slider 3 with the hinge 4 fixed on it. The housing 4 contains gear 5 with an eccentric hole, in which the spherical rolling bearing 6 is installed the hinge axle is seated in it 7. The hinge carrier during operation is a spherical skidding 8 sliding, at ||; mounted in the hull 4. The latter is at 1, and the guides of columns 9 and sleeves 10 are connected with a die section 11 , the matrix of which 12 is fixed with moldable workpiece 13. At the end of the carrier there is a cylindrical If there is a cavity, the end surface of which is made with the angle of inclination / z,. In the boring hole of the z. Press, a spherical thong 14, with the spherical surface of which contacts the flange 15 of the tool holder 16, made in the form of a round plate, on the end of which the tool 17. is fixed. The center of the spherical surface of the baffle 14 is located at the center of the spherical reference EiepxHocTH carrier. The end face of the tool holder 16 is sloped to its axis, as well as the flat surface of the cavity, at an angle. The tool holder & is fixed to the flat surface of the carrier with screws 18. The tool holder and can be reinstalled relative to the axes by 180 ° with the relative position of the carrier and tool holder fixed by means of the slots 19, made in the spherical bolster 14, and the lock 20, fixed on the tool holder with screws 21.

The device works as follows.

An electric motor using a gear (not shown) transmits a vrach gear 5, which, as a result of an eccentric located in the bore of the bearing 6, causes the carrier 7 to oscillate (without vrasha) with an angle of inclination relative to the vertical axis a. Resetting the tool during extrusion, reduction, etc., is performed as follows. The screws 18 are unscrewed, the tool holder 16 is removed and reinstalled in the carrier cavity, and the retainer 20 falls into the groove 19 of the spherical sub 14, located at an angle of 180 ° from the groove in which the retainer was located prior to reinstalling the tool holder. In the position when the angles of inclination of the planes of the carrier and the end of the tool holder are summed, the angle of inclination of the tool 17 k

is () os (see

(see Fig. 1). Angle setting

occurs when the electric motor is turned off; Te; ie, the drive. With the help of a special device, the stoppage of the carrier is made at a certain moment at which the plane of the angle of inclination of the carrier and the carrier coincides with the plane in which the fixing groove of the baffle 14 and the angle of the reference plane of the carrier 7 are located.

5, the spherical device is converted by means of a reinstallation of the tool holder 16 into a traditional stamping press, with which it is possible to perform stamping operations requiring the alignment of the tool. These operations are carried out with the slide moving downward with the drive motor of the spherical device off.
