Abstract

A forming and shearing device for the leads on electronic components permits the simultaneous formation of curved stand-off supports with the trimming of the leads to a desired, correct length. With reference to Figs. 1, 2 and 3, the device comprises a sliding form plate 1 and a sliding cutter plate 2 respectively sliding between, and under, a pair of spaced, fixed plates 3 and 4. These two fixed plates are provided with lead apertures 5 and 6 spaced apart in accordance with the desired lead spacing.

Lead Forming and Trimming for Components

A forming and shearing device for the leads on electronic components permits the simultaneous formation of curved stand-off supports with the trimming of the leads to a desired, correct length. With reference to Figs. 1, 2 and 3, the device comprises a sliding form plate 1 and a sliding cutter plate 2 respectively sliding between, and under, a pair of spaced, fixed plates 3 and 4. These two fixed plates are provided with lead apertures 5 and 6 spaced apart in accordance with the desired lead spacing. With a component's leads 10 passed through the lead apertures, movement of the form plate 1 causes the divergent inner faces 7 and 8 to effect a localized outward bulging 11 of the respective leads, and when the desired bulge has been completed to form standoffs, the lead

ing edge of the cutter plate, lagging behind the form plate, trims the ends 12 of the lead to the correct length. The form plate 1 and the cutter plate 2 are both connected to an air cylinder arm which provides the requisite reciprocal motive force.
