(54) УСТРОЙСТВО ДЛЯ РИХТОВКИ ВЫВОДОВ ТРАНЗИСТОРОВ(54) DEVICE FOR RICHTOV TRANSMISSION OUTPUTS

Изобретение касаетс обработки металлов давлением и относитс к устройствам дл рихтовки выводов электро- и радиодеталей (транзисторов).The invention relates to the processing of metals by pressure and relates to devices for leveling the leads of electrical and radio components (transistors).

Известно устройство дл рихтовки выводов радиодеталей 1, содержащее два ползуна, на одном из которых размещены расчесывающие лезви , а на другом - .клинь . Ползуны имеют скосы, по которым они перемещаютс один относительно другого в одной плоскости. После внедрени между выводами, расчесывающие лезви , закрепленные в ползуне шарнирно, осуществл ют движение в клинь х вдоль выводов от места их креплени к корпусу. Рихтовка производитс , в одной плоскости. После рихтовки выводы остаютс параллельными друг другу, а не отклоненными под углом к оси, как требуетс дл автоматизированного монтажа . При рихтовке воздаютс осевые усили , которые могут привести к бракуиздели . Недостатком устройства вл етс невозможность рихтовки выводов в двух взаимно перпендикул рных плоскост х и исключени х осевых усилий на выводы.A device is known for straightening the leads of radio components 1, containing two sliders, on one of which combing blades are placed, and on the other - a wedge. Sliders have bevels in which they move relative to one another in the same plane. After insertion between the leads, combing the blades, hinged in the slider, move in wedges along the leads from the point of their attachment to the housing. Straightening is done in the same plane. After leveling, the leads remain parallel to each other, rather than deflected at an angle to the axis, as is required for automated installation. When straightening, axial forces are exerted that can lead to marriage. The drawback of the device is the impossibility of leveling the leads in two mutually perpendicular planes and excluding the axial forces on the leads.

В предлагаемом устройстве, содержащем два расположенных в направл ющих ползуна , на одном из которых размещены расчесывающие клинь со скосами, а на другом - пуансоны, имеетс механизм изменени рассто ни между расчесывающими клинь ми, а боковые пуансоны снабжены ловител ми и размещены на ползуне с возможностью взаимодействи со скосами клиньев посредством пружины. С целью фиксации выводов под углом к его оси дл последующего автоматизированного монтажа на платы, расчесывающие клинь вы10 полнены с конусной задней гранью.In the proposed device, which contains two slides located in the guides, one of which contains combing wedges with bevels, and the other punches, there is a mechanism for changing the distance between the combing wedges, and side punches are equipped with catchers and placed on the slider with interaction with bevels of wedges by means of a spring. In order to fix the leads at an angle to its axis for subsequent automated installation on the boards, combing the wedges are completed with a tapered rear edge.

Claims

On the lower slider 1 there are two combing wedges 2 connected by a screw 3. In the upper slider 4 a punch 5 is fixed and side punches 7 are fixed by means of a spring 6. The punches 7 are equipped with catchers 8 in the form of combs with teeth. The radio component (transistor) is mounted on the lower slider so that its two terminals 9 are in the horizontal plane, and the third (middle) is below them. The transistor is mounted by a collet (not shown in the drawings). Slides 1 and 4 are separated so that a gap is provided for the free passage of the transistor leads. Grip with a fixed transistor; under: led from the point of the wedges 2. The device works as follows, When the lower slider moves, 1 wedge 2 enters the gap between the terminals. When the extreme ends are touching the base of the wedges, turning the screw 3, the wedges 2 approach each other, the richth is the average output in the horizontal plane. After that, the upper crawler 4 begins to move. The stationary punch 5 enters the groove formed by the wedges and provides a leveling of the middle lead in the vertical plane. The side punches 7, due to the presence of the spring b, slide along the bevels of the wedges 2, moving the extreme, conclusions to their base. At the same time, the catchers of punches provide the correct position of the horizontal leads, turning them aside. After the end of the movement of the slider 4, the teeth of the catchers 8 will enter the lower recesses of the slider, ensuring rigid fixation of the horizontal leads. The upper slider can do several blows, forging by forging. The deviation of conclusions at a certain angle from the axis is provided by a wedge shape. Claim 1. Device for straightening the leads of transistors, containing two sliders arranged in guides, on one of which there is a combing wedge with bevels, and on the other punches, characterized in that two mutually perpendicular planes and exclusion of axial forces on the conclusions, it is equipped with a mechanism for changing the distance between the combing wedges and catchers placed on the punches, while the punches are placed on the slide to cooperate with wedge bevels by means of the pressure spring.

2. The device according to claim 1, characterized in that, in order to fix the leads of the transistors at an angle to its axis for subsequent automated mounting of the transistors to the boards, combing the wedge is made with a tapered back face. Information sources taken into account in the examination 1. U.S. Patent No. 3520336, Cl. 140-147, 1970.
