Description

Production process and device of high-solid-content self-adhesive enameled wire

Technical Field

The invention relates to a production process of an enameled wire, in particular to a production process and a production device of a high-solid-content self-adhesive enameled wire.

Background

The enameled wire can be wound to a wire coil by a winding machine after being processed, and the enameled wire on the wire coil is drawn out by a pay-off machine for subsequent use and then is wound. However, when the conventional paying-off machine draws the wire, the wire coil is horizontally placed on the ground, and the enameled wire is drawn from the upper side, so that the enameled wire can be contacted with the edge of the flange at the end of the wire coil to be bent when being drawn, and the enameled wire is worn. And along with taking out gradually of enameled wire, the enameled wire that is located the drum inlayer can and the lateral distance at baffle edge crescent, leads to the angle of bending and the wearing and tearing effect of enameled wire also can aggravate thereupon to further influence the stability of enameled wire. Although the bending effect has small influence on the enameled wire with a large wire diameter at present, the fine enameled wire with the diameter less than 0.1mm is easy to break during paying off; in order to improve the paying-off stability of the enameled wire, manufacturers generally adopt a wire coil with the specification of below 120mm to wind the micro enameled wire, namely, the transverse distance between an inner layer enameled wire in the wire coil and a rib of the wire coil is reduced, so that the bending amplitude and the wire breakage rate of the enameled wire during paying-off are reduced. However, the reduction of the wire coil specification means the reduction of the wire take-up capacity, the capacity of the conventional wire coil with the specification of 120mm is generally within 4kg, and the production and transportation cost of the enameled wire is increased, so that the economic benefit of manufacturers is damaged.

In addition, with the gradual improvement of the current environmental protection standard, the wire enamel with high solid content is more and more widely applied to the wire enamel due to the characteristics of less solvent and small volatilization of harmful components. Meanwhile, the self-adhesive wire enamel can be bonded for the second time by heating or electrifying, so that the gaps in the wire grooves can be filled after the wire is wound, and compared with the conventional wire enamel, the wire enamel dipping process is reduced, and good economic benefit and environmental protection effect are brought. Under the effect, the self-adhesive enameled wire with high solid content becomes the research focus of the current manufacturers.

However, the current method for electrifying the enameled wire after winding is simpler, and the wiring end of the winding motor is directly connected with the power generation module and then electrified by the power generation module. However, in this way, on one hand, the motor needs to be installed and wired manually, so that the power-on equipment is often in an idle state, and the power-on efficiency is low. On the other hand, the motor is not protected in the electrifying process, so that the motor is easy to be broken by external collision to influence the electrifying stability of equipment; and the installer is easy to touch the electrified part by mistake to cause electric shock, so that the safety hazard is high.

Therefore, the existing self-adhesive enameled wire with high solid content of less than 0.1mm has the problems of high production cost, low production efficiency and poor safety.

The working principle of the invention is as follows: during production, the wire drawing machine, the annealing furnace and the enamelling furnace sequentially perform wire drawing, annealing and film coating processes on a copper wire to form a required self-adhesive enameled wire with high solid content, and then the enameled wire after being processed is wound into a wire coil 3 by the wire winding machine. When the take-up machine works, a wire coil 3 is sleeved on a support frame 6 and locked through a round nut, then the torque motor 5 drives the wire coil 3 to take up wires through a mandrel 2, and meanwhile wire arrangement is carried out through a lead slider 4, so that enameled wires are arranged in the wire coil 3 layer by layer. In the winding process, the weight of the wire coil 3 is detected by the weighing sensor 7, and the working voltage of the torque motor is adjusted by the control system after the weight reaches a threshold value, so that the torque and the rotating speed of the torque motor on the wire coil can be correspondingly reduced after the voltage is reduced, the extrusion of the enameled wire on the inner layer of the enameled wire in the winding process is reduced, and the stability and the structural strength of the enameled wire after winding are improved. Meanwhile, the distance sensor 10 can also move transversely along with the lead slider 4, and the thickness of the wire layer on the wire coil 3 is detected in the moving process; when the line layer thickness of certain position is higher than other positions on the drum, then can adjust the translation rate of lead wire slider 4 in this position through control system, and then make the winding displacement on the drum 3 can keep in even thickness range, avoid causing the extrusion between the enameled wire impaired because of the winding displacement is too close, further improve the rolling effect to the enameled wire.

The enameled wire is stored and transported in a wire coiling mode after being wound, the wire coiling is drawn out by a pay-off machine during subsequent use and then wound on a motor stator through a winding machine, the enameled wire is electrified by an electrifying device, so that a high-solid-content self-adhesive paint film on the surface of the enameled wire can be converted into a semi-molten state and subjected to secondary adhesion after being electrified, gaps in a stator wire slot are filled, and the slot fullness rate of a motor is improved. Because the extension and the extrusion damage of enameled wire in the rolling in-process can be avoided to the enameled wire under above-mentioned cooperation for the problem of broken string can not appear because of buckling at the unwrapping wire in-process of enameled wire, improves the unwrapping wire stability of enameled wire. Under the effect, the wire coil with the specification of 160mm can be used for winding, so that the capacity of the enameled wire of each wire coil can reach 10kg, the production efficiency of the enameled wire is effectively improved compared with the existing production process, and the corresponding production cost is saved.

When the enameled wire is electrified, a treating person firstly installs a motor to be electrified on the fixed seat 13 and connects the wire outlet end of the motor with the electric clamp 14; after wiring, the treating personnel horizontally move the protection plate 15 again to enable the sliding seat 17 on one side and the compression spring 19 to be attached to each other; at this time, the contact sensor 20 and the slide holder 17 are displaced from each other, and the pinch roller 25 is located at the edge of the V-shaped pipe 26 in the horizontal direction.

After the protection plate 15 is in place, a worker rotates the control handle 24, so that the control handle 24 drives the inner ring 22 to rotate after rotating, the inner ring 22 pulls the swinging piece 23 through the lantern ring 28 in the rotating process, and the swinging piece 23 swings towards the V-shaped pipe 26 after being pulled. When the swinging piece 23 swings inward, the pressing wheel 25 at the end part gradually draws close to the inner side along the V-shaped surface of the V-shaped pipe 26, so that the protection plate 15 is driven by the outer ring body 21 to move transversely, and the protection plate 15 can overcome the elastic force of the compression spring 19 and compress the compression spring 19 when moving. When pinch roller 25 rotates to and spacing step 261 mutual laminating, pinch roller 25 is located the center of V-arrangement pipe 26 on the horizontal direction, and sliding seat 17 sideslip is to laminating completely with contact sensor 20 simultaneously for contact sensor 20 can open the power module after detecting and carry out the circular telegram processing to the motor.

When the motor is powered on, the protective plate 15 can be limited in the transverse position through the matching of the pinch roller 25 and the V-shaped pipe 26, and the power failure of the power generation module caused by the deviation of the protective plate 15 when the lateral force is applied is avoided; meanwhile, the compression spring 19 can pre-tighten the protection plate 15 after compression, and then the limiting of the compression wheel 25 is matched to play a clamping effect, so that the possibility that the protection plate 15 rotates and loosens after being vibrated is relieved and the control handle 24 is vibrated. When the control handle 24 is rotated to the right position, the clamping block 222 on the inner ring 22 is located at the end of the arc-shaped strip 212, and the outer ring 21 at the position of the sliding groove 211 is slightly deformed through interference fit of the clamping block and the arc-shaped strip, so that the inner ring 22 is pressed by virtue of the deformation effect, the control handle 24 is prevented from being loosened in the electrifying process, and the electrifying stability of the invention is improved.

Under the effect, the protection plate 15 can realize a stable protection effect when being electrified, and avoid electric shock caused by mistaken touch of external personnel when being electrified; when the protection plate 15 moves accidentally, the power generation module can be powered off under the induction of the contact sensor 20, so that the problem of electric shock is further avoided, and the protection plate has good stability and safety. Under the protection effect of the protection plate 15, the treating personnel can stably avoid the contact with the electrified part, so that the motor can be arranged on the fixed seat 13 at the other side in the electrifying process, and the treating efficiency of the invention is improved. After the electrification is finished, the power failure can be finished by loosening the control handle 24 and sliding the protection plate 15 by a treating person; when the protection plate 15 is in a free sliding state, the compression spring 19 at the end part can play a role in blocking the protection plate 15, so that the sliding seat 17 cannot slide to the position overlapped with the contact sensor 20 in the free state, the mistaken electrification of the invention is further avoided, and the safety of the invention is further improved.
