SU1253698A1 - Method of deformation of blanks - Google Patents

Description

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

The aim of the invention is the expansion of technological capabilities and the intensification of the process.

The drawing shows the design of the press for carrying out the method. In the guides of the press frame 1, a slider 2 is mounted on which the device 3 is fixed. The slider 4 reciprocates along the groove 5, which informs it 6 to connect the axis 7 of the eccentric 8 to the axis 9 located in the crawler 4. The carrier 10, connected to the axis 7, receives a swinging movement in the same vertical plane (panic motion). Due to the fact that the axis 11 pressed into the housing can move along the groove 12, the carrier is fixed and the punch 13 with its working points has no spread with sliding on the workpiece 14 placed in the matrix 15.

reversing the deformation of the workpiece 14, the slider 2 slows down the axial movement and the sensor 16 of the speed of movement of the slider 2 gives a signal to the thyristor controller 17 for smoothly adjusting the revolutions of the motor 18, transmitting the rotational movement of the axis 19, which rotates the eccentric 8,

As the deformation resistance of the workpiece 14 increases and the axial movement of the slide 2 slows down, the motor 18 increases the speed, which leads to an increase in the oscillatory movements of the carrier 10 per unit of time, and this contributes to the intensification of the process of deforming the workpiece 14,

The proposed method contributes to the intensification of the process, since the deformation rate (the number of oscillations per unit time) has a softening effect on the deforming material, increases the amount of heat of plastic deformation, and heats the metal. An increase in temperature leads to an intense softening of the metal.
