SU1253697A1 - Method of spheroidizing stamping of blanks - Google Patents

Description

one

The invention relates to the processing of metals by pressure and may find application in the engineering industries.

The aim of the invention is to reduce energy consumption and intensify the process.

The drawing shows the structure of the device for implementing the method.

On the press frame 1, reciprocating movement of the slide 2 from the drive 3 is performed. On the slide the spherical device 4 is rigidly fixed. The engine 5 through the gearbox 6 and the shaft 7 rotates the gear system (not shown) in the sphere of the rover 4, This rotational movement turns into the circular rocking tool holder 8 and the punch 9. The workpiece 10, laid in the matrix 11, mounted on the die plate 12,

fixed on the table 13, the precipitation is deformed on the side of the punch 9. With an increase in the deformation resistance of the workpiece 10 5, the slider slows down the axial advancement and the sensor 14 of the speed of the creep movement gives a signal to the thyristor controller 5 for smoothly adjusting the revolutions of the engine 5 of the spherical device 4 increasing deformation resistance and slowing the progress of the slider 2, the number of revolutions of the engine increases.

The proposed method contributes to the intensification of the process, since the deformation rate has a softening effect on the deformable metal, increases the amount of heat of plastic deformation and heats the metal. An increase in temperature leads to an intense softening. With a rocking tool, the effect increases. 25,
