Description

nopvtufla T, Coils can be connected either separately or simultaneously with the help of switches 9 and 10. When switched on, both of their coils oscillate in the longitudinal and transverse directions are folded (see, fig. 2). The motion of the core in the region is described by the equations X a – Co5; Y.Ob8lnoC. Square both sides of the equation and add it; their term by term, this is the equation of a circle, the investigator: but, the trajectories of the movement are the surroundings of the radius A with the center at the beginning. The start of the count lies at the point, N and the circumferential motion occurs in the direction of the arrow with a frequency of 100 Hz. The upper and lower coils of the same direction are connected in series with capacitors 11 and 12, the capacitance of which provides a phase shift of the voltage amplitude by 1/4 period. Due to this, the amplitude (A) of the oscillations of the electrically-driven vibrator is mixed by 1/2 of the period T., and thus the deflection angle of the wire is doubled. The amplitude of oscillations of the core is regulated by resistances 13 and 14 within the limits 0-0, 2 mm. Such values are sufficient to obtain the required angles of inclination (with a thickness of 3–10 mm) or required gaps at an output of 30–100 µm along the entire contour, for example, for precision punches. With the help of the proposed device, it is possible to process parts in variants, depending on the arrangement of harvesting and the inclusion of vibrators: parts with inclined forming a small magnitude of up to 1 ° (see, fig. 3, a); and parts with oblique forming a large size-more than 1 (see Fig, 3, b) and parts with forming in the form of broken lines (see Fig. 3, c).

For small-scale breakdowns, the billet is placed closer to the fixed guide jaw and includes one of the vibrators. The longitudinal feed loop is processed with the vibrator's transverse coil turned on, and the transverse current is applied in series with capacitors, the capacitance of which is chosen from the conditions of the phase shift of the amplitude of the voltage of each vibrator by 1 / period and the coils of one direction by 1/4 period. when the vibrator's longitudinal coil is turned on, when processing a contour located below to the guides of the coordinate table not equal to 90 ° or along the radius, they include both vibrator coils. When machining parts with inclined, forming a large size, the edge of the workpiece is placed in the middle of the distance between the guide jaws and includes both vibrators. When processing the contours with the generators. In the form of a broken line, the preform is positioned so that the intersection point of the generatrix line is located in the middle of the distance between the guide jaws, and also includes both vibrators. The treatment in the last two variants is carried out as follows: when processing longitudinal feed, include transverse rolls of the upper and lower vibrators, when processing cross feed, longitudinal rolls, when processing a contour along the radius, all four rolls. The design provides high accuracy and performance. The effectiveness of the device is ensured by the absence of rearrangements after processing each line of the circuit and the simultaneous activation of the vibrator rolls and feed drives. The invention is a device for electroerosive cutting of complex circuits with inclined electrode-wire, rewind along the jaws located on both sides of the workpiece, using a guiding mechanism, characterized in that, the guiding mechanism consists of two vibrators in each of the core rigidly fixed on the said sponge and two electromagnets arranged mutually perpendicularly. coils which are connected to the network re
