Description

The known automatic machines for the manufacture of coils from bell wire to electrical detonators FOR mining operations, equipped with a rotary formers with a rotary plug for winding the wire, do not allow the manufacture of coils with stripped (bare) wire sections and twisted ends.

The proposed machine, with the aim of producing coils with stripped wire sections and twisted ends, is made with two movable carriages, one of which is equipped with rotating sharps for stripping the wire, and the other with turning punches for trimming the stripped wire and spindles for twisting the bare ends of the coils. In this case, the fingers of the forks of the automat are rotated in two PLANES and are rotated when the spindles of the spindles located on the moving carriages are formed.

The drawing shows the kinematic scheme of the proposed device.

The camshaft 1 is driven through the pin 2 from the electric motor (not shown). On the camshaft 1 on the hub 3 with the Maltese cross 4, a movable reel 5 is mounted, which through the cross 4 is driven by a lever 6 fixed on the roller 7.

Roller 7 rotates with a pair of gears

8. For one revolution of the camshaft / Maltese cross 4 with a reel 5 will rotate around its axis by / 4 part full

turnover.

Four forks mounted on reel 5

9, which are brought into periodic rotation-around their axes 10 from a fixed conical sector, // fixed on

plate base (not shown). Each fork 9 has but two finger holders 12 with fingers 13 inserted into them. The finger holders are rotated by means of shpindles 14, which receive rotation

from the cams 15 through the racks 16 and the corresponding gears. On the left side of the reel 5, the movable carriage 17 of the sharks 18 is open, on the right side, on the carriage 19 of the head 20 with rotary punches (not shown) for cutting the bare wire and twisting the ends. The movable carriage 17 is fed progressively to the wires from the cam 21 via a gear 22, 23, 24, 25, and the movable carriage 19 is

from the cam 26 through the gear train 27, 28, 29, 30. In this case, the buckle 18 is driven through the belt drive from the shchikov 31 and 32, and the head 20 for trimming and twisting the ends rotates from the cam 33 through the system 41, intended for cable removal after trimming and twisting the ends to the first manual feed position, is rotated through the levers 42, the ratchet wheel 43 and the gear wheel 44 and 45.

The roller 46 is intended for the continuous unwinding of the wires 48 of the coils 49.

To turn on the machine, wire 48 is manually filled from coils 49 through rollers 47 and 46. From roller 41, wires are inserted into the grooves of the fingers 13 of the right upper plug 9. The reel 5 turns around its axis and the wires begin to wind on fingers 13. After turning the reel 5, the inlet 9 with imotaped wires becomes iodine at an angle of 45 ° on the opposite side of its original position. The second plug 9, lifting from the bottom out from under the wires, seizes the wires into the grooves of the paldev 13 and, together with the wires, stands in the same position as the previous plug 9. The location of the plugs 9 is not equal to the wires; The right fork is located parallel to the direction of the wires, and the left is perpendicular. After turning the reel 5, the moving carriage 17 of the slings is fed and the insulating sheath is removed from the copper wire. Then, the carriage 17 is retracted to its original position and a gotovka 20 with rotary punches is supplied to the wires to trim the stripped

wires and shpinddel for twisting bare K01 SHCHOV coils. The ends twisted by the head 20 are brought closer to the ends of the right upper fork 9 with the roller 47 and the machine is prepared for the filling. The removal of the skein is made by a pin (not shown in the drawing) inside the fingers 13 raised by the cam 52.

The machine provides complete mechanization of the manufacture of coils of wire for electric detonators.

Subject invention

1. An automatic machine for making coils from a bell ring, equipped with a reel with rotary plugs for winding a rod, characterized in that, for the purpose of producing coils with stripped (bare) sections of wire and twisted ends, the machine is made with two movable carriages, one of which is equipped striking balls for stripping wire, and the other - with swiveling punches for trimming the stripped wire and spies for twisting the bare ends of the coils.

2. Automatic but also. 1, characterized in that, in order to make the coils with transverse windings, the fingers of the forks of the reel of the automaton are rotatable in two planes and are rotated in the formation of transverse windings with shpindles located on movable carriages.
