Description

The invention relates to the processing of metals by pressure and is intended for the manufacture of wire jumpers installed on printed circuit boards.

The aim of the invention is the expansion of technological capabilities.

FIG. 1 shows a kinematic diagram of the device; in fig. 2 - bending mechanism.

The device contains (Fig. 1) the electrical device operates as follows. The wire from the coil 7 through the correct device 6 enters the matrix 8. The mechanism 5 is flexible, which is driven into rotation from the electric motor in the gripping section when the lever 10 with the knife 11 is in the unfolded position Does not touch the wire, but passes it by.

On the section of the wire clamp, the working profile of the cam 9 ensures reliable

on the ledge of the cam 9, sets the movement of the lever 10 with a knife 11, which cuts off the finished jumper. She falls into a tara. When cut, the groove in the matrix provides a 20 knife entry. At this point, the second knife enters

cam 9 and two levers 10, located on the matrix at an angle of 180 °. On the levers attached to the MS removable knives 11, rollers 12, springs 13 return the levers to their original position.

the clamping zone and, having seized the wire, the clamping cam profile is made in such a way that it fits to the matrix. With the rotation of the mecharaze, in order to ensure the seizure of the conductance of the bend, the cycle is repeated,
