Abstract

The invention relates to matrix printing tools and allows for enhanced functionality and improved print quality. When axially acting on the punch, its actuator additionally informs it of vibrations in the direction perpendicular to the direction of its movement during printing. To communicate the transverse vibrations, an electromagnetic drive with a movable bark is used, in which a guide channel is provided for installing a punch in it. 1 il.

Description

the frequency and at the moment of time coinciding or not coinciding (depending on the optical density of the print) with the drive of the 12 punches

The actuator 12 and the initiator 5 start to operate simultaneously. Anchor 7, under the driving magnetic field of coil 9, begins to vibrate, for example, with frequency f, periodically turning around axis 0 through an angle ± q, channel 8 begins to shift by the same angle h of its original position. With about three inches, the opposite ends of the channel 8 begin to interact with a part of the surface of the punch 1, jointly wavy oscillations with the frequency of excitation f the whole punch, and the relative average size of the hole in the channel 8 decreases by the magnitude, the equivalent optical density of the original elements

At the time of contact of the punch 1 with b by the magic 13, the kinematic energy accumulated in the punch (or in its additional mass, for example, in the crust: 1 electric drive 12), turns into a potential impact energy, the pulse compression energy of the punch — beauty — roller — roller. The sharpening the pusher 1 is more, the rigidity C (punch) depends on the frequency and amplitude of oscillations of the core 7 of the mechanical modulator - vibrator 5, the smaller the slot in channel 8, the smaller the punch deflection at the moment of impact, the greater energy is transferred to elem print envelope, more ink is transferred to the well, higher optical density of the print

If the elements of the image decomposition column have a different optical density, then the column is printed sequentially, with each punch 1 in the matrix being reported from initiator 5 by different ultrasonic vibrations (with different frequencies and amplitudes).
