The invention relates to mechanical engineering and can be used in the manufacture of the igniter and electric detonators for mining operations.
Known machine manufacturing coils of wire, carrying the measuring wire and pruning, which consists of two parallel screws, rotating around its axis and around a common axis of symmetry. When rotating around a common axis is winding wire, and when the rotation of the screw is offset from the coil to the edge, where it is cut and removed from the screw (U.S. Patent No. 2527662, CL 242-53 1971).
The advantage of this machine is that it is due to the measuring can produce coils of a given length starting from a certain minimum.
The disadvantage of this machine is that it does not clears the ends of the conductors.
As a prototype renting a machine for the manufacture of coils of wire placed on the pivot housing mechanisms engaged in the longitudinal and transverse winding, cutting and trimming of the ends of the conductors (Copyright certificate №738028, H 02 G 1/12, 1976).
The disadvantage of this machine is to manufacture coils of only one length.
The purpose of the invention is to expand the range of manufactured machine coils of wire.
This goal is achieved by the fact that in the machine manufacture of coils of wire, terasem two coils with the stock wires, node straightening, drive, stacker wires, a rotatable housing with nodes cutting and Stripping wires, the longitudinal and transverse winding, a reset of the finished coil of wire, a software device consisting of a kinematically connected between a sector gear with a sector copier, which is installed coaxially with the opportunity to interact with the rotating body, and a disk with a sector copier, Manager stacker wires and the mechanism of locking sector gear, additionally there is the rpm sensor swivel housing, counter, solenoid, key inclusion on the shaft of the sector disc, interacting in such a way that when the preset number of revolutions counter includes a solenoid which releases the key on and the disk with a sector copier performs one revolution.
Figure 1 shows a machine for the manufacture of coils of wire.
Figure 2 shows the kinematic diagram of the machine manufacturing coils of wire.
Machine manufacturing coils of wire, shown in figure 1, consists of the frame (position 1), drive (2), a rotary body (3) with the node cutting and Stripping the insulation from the wire ends (pos.4), host of the longitudinal and transverse winding (5), node reset ready coil wire (pos.6).
Software the device consists of a sector gear (pos.7) and disk (pos.8) with a sector copier (p is s, 10, 11), which interact with the locking mechanism (pos.12) sector gear (pos.7), stacker wire (POS) and pneumatic valve (POS).
On the side of the stacker wire (POS) posted by two straightening node (POS) and two coils (POS) with the stock wires.
Figure 2 additionally shows the locking mechanism (pos.12) sector gear (pos.7), rpm sensor (pos.16) rotary body (3), count (pos.17), the solenoid (pos.18), key inclusion (POS), gear (POS) drive shaft and gear (POS) output shaft, gear (pot and 23)and the levers (24) of the node of the longitudinal and transverse winding (5).
Machine manufacturing coils of wire works as follows.
In the initial state, the solenoid (pos.18) de-energized, the key enable (POS) is turned off and the rotation of the gears (POS and 21) is not transmitted to the sector disc (pos.8). Sector gear (pos.12) occupies its original position relative to the rotary body (3). When this gear (.23) is located at the edge of the gear sector gear (pos.7).
Wire coils (POS), after passing through the straightening unit (POS) and stacker wire (POS), are fixed to the levers (24). When turning on the actuator (2) the rotary body (3) is rotated counterclockwise. The wire begins to gather around protruding levers (24) of the node of the longitudinal and transverse winding pos.5). The signal from the rpm sensor swivel housing (pos.16) summarized techdecades counter (pos.17). The outputs of the counter (pos.17) in unitary decimal code served on switches that have the specified number of turns. When the preset value is given intermittent signal to the solenoid (pos.18), which releases the key enable (POS).
Drive (pos.8) with a sector copier starts to rotate 360°. Sector copier (position 9) turns stacker wire (POS) in the host side of the cutting and Stripping (pos.4).
Upon further displacement of the rotary body (3) wires are placed in the node cutting and Stripping (pos.4), which then is clamped, cut and remove the insulation from the ends of the cut wire. After that, the stacker wire (POS) returns to its original position.
Sector copier (10) includes a locking mechanism (pos.12) sector gear (pos.7), which up to this point rotated together with the rotary body (3). When the stop sector gear (pos.7) rolls bevel gear (POS) and through the gear (.23) transmits the rotation to the node of the longitudinal and transverse winding (5). This causes the transverse winding. At this point is pulling the cut ends of the wires from a node cut of innate isolation (pos.4).
The ends of the wires coming from the stacker wire (POS), held by the node cutting and Stripping (pos.4) before winding the next coil of wire.
Once wound, the levers (24) are installed in the original position and raspoliruyte. Next comes in the node reset (pos.6), the plate which is placed at the center of the rotary body, relieve the finished coil of wire.
Copier (pos.11) includes short pneumocele (POS)applying a stream of air at the site of the cutting and Stripping (pos.4) to remove the removed insulation.
At this time, the disk (pos.8) with a sector copier (position 9, 10, 11) makes one revolution and the key enable (POS) is disconnected from the drive (pos.2). At the same time disables the locking mechanism (pos.12). The levers (24) of the node of the longitudinal and transverse winding (5) fixed in position complete longitudinal winding.
Next, the manufacturing cycle of the strand of wire is repeated.
The length of wire on a reel is defined as the sum of the number of longitudinal coils wound on the levers (24) of the node of the longitudinal and transverse winding (5) and a fixed part determined by the kinematics of the boot.
Using switches on the meter (pos.17) sets the number of longitudinal coils, and install the levers (24) with different geometric sizes to alter the length of one turn.
pity sample machine produces coils of wire length from 0.3 to 5 meters
Thus, fabrication of a prototype machine for the manufacture of coils of wire and the test confirms that the previously set goals. This allows us to consider the proposed solution meets the criterion of "industrial application" and "novelty."
