The invention relates to jexnono-uc-plumming equipment for heavy-duty radio equipment, in particular, devices for simultaneously bending and cutting the leads, and can be used to prepare the planarip chips for mounting on printed circuit boards.

Child - the expansion of technological capabilities.

Pa figs. Figure 1 shows a device for forming microcircuit pins, twisted from the side, a cut in the plane coinciding with the direction of feed of the microcircuit (in two positions: left in the open position, right in the closed position, left in the pocket for trimmings made deaf, in the right - through) ;

in fig. 2 - the device, a section in the flat surface, perpendicular to the direction of supply of the chip; in fig. 3 - a fragment of a longitudinal section of a part of the device along the centering grooves (on the right - the pins of the microcircuit in the position before the molding, on the left - after the unloading of the microcircuit); in fig. 4 shows a section A-A along a plane coinciding with the connector line of the centering grooves in FIG. 3

The device for forming the leads of the pixels contains the upper plate 1, on which the die for cutting with the four cut-off knives 2 is installed.

In the cavity of this matrix a bending matrix 3 is installed with four working elements on each side of the perimeter “Inside the bending matrix

That her four groups of conclusions were grounded by pairwise different elements of tools. The conditions for bending lateral leads are created between the grooves, and the front and rear groups of leads directly by the clamping elements 4.

Further, as the upper part is lowered, the power rods 8 and 9 of the first provide sufficient clamping force for the leads, and the second result in a flexible matrix with four parts 3.

Further, after the bend of the protrusion of the ridge and the system of the links 11, 3, 4, R and 9 has stopped, the knives of the matrix 2 of the inspection section of the segment of conclusions when n 1aim..device of four with the elements of pu / .nson-; nineteen ,

The process of fopmiani of the conclusions of the microcircuits „; During the reverse course, it is all-time; on the nza.gmodeys gnu g in the reverse v. Sledona i apyyusti. The knives of the milligree 2 are the first to retract, a bending matrix with elements of 3 presses 4. At which the ejector 14 is raised. , Ianet. the gutters 17 and 19 are consumed, the batten 10 departs and releases the microcircuit from the prices of the spinning action of the pins of the additional centering element 23.

Thus, the proposed device provides an increase in the point of centering of the microcircuit relative to the tools, and also provides the possibility of forming microcircuits with four groups of leads, i.e. The device is suitable for forming pins approximately and from two and three sides of the microcircuit.
