Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of non-ferrous metal processing, and particularly relates to a metal wire lubricating coating coating production line. BACKGROUND

[0002] In the metal wire processing process, the wire processed by the previous process has poor surface roughness, which affects the post-processing of the wire. In the actual production process, a uniform thickness lubricating coating needs to be brushed on the surface of the metal wire to solve the problems existing in the post-processing of the wire product. To achieve the above goal, patent numbers [ZL201510578035.8] and [ZL201510579272.6] propose an immersion coating method, but due to design defects, the system has problems such as high center line of the take-up, poor equipment stability, and low automation, which cannot realize the continuous production of the metal wire. To solve the above problems, the patent number [ZL201620357611.6] proposes a pre-bending and then coating processing method, which effectively solves the problems of high center line of the coating system and cannot realize continuous production. However, since it does not consider the process requirements of some types of metal wires that do not need to be polished or need to be polished multiple times before coating, the coating of this type of wire cannot be realized. At the same time, the system does not consider that the mismatch between the wire feeding and take-up speed of the metal wire will cause the wire to deviate from the center of the arc-shaped induction coil and rub against the arc-shaped induction coil, causing sparking, burning of the wire, damage to the equipment, and even quality and safety accidents. In addition, it does not consider that the coating quality is affected by changes in air temperature and other factors, and also has problems such as low stability, low yield, and low automation.

The belt traction machine 5-1 and the take-up machine body 5-2 adopt a constant torque mode to prevent speed mismatch between the belt traction machine 5-1 and the take-up machine body 5-2 from causing abnormal alarm of the motor and other problems.

[0038] The wire coated by the production line is dry and smooth, without falling off, air holes, and vertical flow scar phenomena. The detected lubricating coating has the characteristics of uniform thickness, tight combination, and strong adhesion.

[0039] The application is used for on-line self-adaptive continuous coating operation of suitable coated metal coil wire, and the specific working process is as follows:

[0040] 1. Pre-examination work:

[0041] 1) Check that the adjustable damping vertical pay-off device 1 is empty of material, the damping brake disc 1-3 is in the open state, and the rotating disc 1-2 can rotate freely;

[0042] 2) Check that the water level in the cooling device 2 is normal, and the connecting pipeline is sealed well without leakage;

[0043] 3) Check that the surface of the arc-shaped induction coil 3-2 is well insulated;

[0044] 4) Check that the water level of the water bath heating device 4-12 is normal, and the circulating pipeline is sealed well without leakage;

[0045] 5) Check that the coating liquid level in the mixing device 4-14 is normal, the coating has no agglomeration, and the liquid supply and return pipeline is not damaged;

[0046] 6) Check that the belt traction speed measuring take-up device 5 is at the original position.

[0047] 2. Preparatory work and threading work:

[0048] 1) Start the cooling device 2 to supply cooling water to the induction power supply system 3;

[0049] 2) Set the preheating temperature of the water bath heating device 4-12, and start the device;

[0050] 3) Start the mixing device 4-14, and the coating starts to be stirred in the mixing device;

[0051] 4) Adjust the expansion and contraction diameter of the I-shaped expansion and contraction wheel 5-3 to the appropriate position;

[0052] 5) Take a coil of suitable coated coil wire after treatment and place it on the rotating disc 1-1 of the adjustable damping vertical pay-off device 1, manually adjust the opening and closing angle of the damping brake disc 1-3 to make the adjustable damping pay-off device 1 have a certain resistance;

[0053] 6) Open the straightening device 4-1, manually pull one end of the wire into the straightening device 4-1, close the straightening device 4-1, and adjust the guide wheel of the straightening device 4-1 to the appropriate position;

[0054] 7) power the servo motor 4-2-11 for pre-bending rotation, drive the lower bending guide wheel 4-2-10 to move downward to the original position, supply air to the cylinder 4-2-3 to drive the upper belt assembly 4-2-5 to move upward, so that a certain gap is generated between the upper belt assembly 4-2-5 and the lower belt assembly 4-2-6. The manual traction wire is sent into the gap between the upper belt assembly 4-2-5 and the lower belt assembly 4-2-6, and at the same time, the air supply to the cylinder 4-2-3 is reversed to drive the upper belt assembly 4-2-5 to move downward to the position where the wire is completely pressed by the belt;

[0055] 8) power the servo motor 4-2-2 for traction, drive the belt 4-2-7 to rotate, and use the friction between the belt 4-2-7 and the wire to transmit the wire head to the right end of the guide wheel on the right side of the upper bending guide wheel 4-2-9. Set the wire diameter and bending radius, and the program automatically reverses the power supply to the servo motor 4-2-11 for pre-bending lifting to drive the lower bending guide wheel 4-2-10 to move upward to the specified position to bend the wire head;

[0056] 9) At the same time, power the servo motor 4-2-2 for traction and the servo motor 4-2-11 for pre-bending lifting, and the wire is continuously fed into the bending under the joint action of the belt and the bending wheel. The pre-bent wire passes through the cross roller assembly 4-5 and the guide wheel assembly 4-7 in turn, enters from the bottom of the paint tank 4-9, comes out of the upper opening, passes through the center of the arc-shaped induction coil 3-2, pushes the balance lever 4-10-3, makes the outer side of the guide wheel 4-10-4 of the speed measuring guide wheel assembly 4-10 contact with the wire, passes through the rear cross roller assembly, enters the belt traction machine 5-1 of the belt traction speed measuring take-up device 5, and finally fixes the wire head to the I-shaped expansion and contraction wheel 5-3;

[0057] 10) Point adjustment of the belt and bending wheel of the belt traction pre-bending device 4-2 is observed. The offset position of the wire relative to the center of the arc-shaped induction coil 3-2 and the swing direction of the balance lever 4-10-3 in the speed measuring guide wheel assembly 4-10 are observed. The wire is basically in the center position of the arc-shaped induction coil 3-2 before the device is started, and the displacement recorded by the displacement sensor assembly 4-6 at this time is set as zero point and confirmed;

[0058] 11) Use special coating material to wrap the wire to a certain diameter, and insert it into the wire inlet at the bottom of the paint tank 4-9. Fill the gap and repeatedly swing to make the coating material completely contact with the wire and can slide relative to each other. This process is used to block the gap between the paint tank 4-9 and the wire, without causing paint leakage.

[0059] 12) Start the paint pump 4-13, and the paint starts to circulate and pump into the paint tank 4-9, completely immersing the wire within the range of the paint tank 4-9, and basically keeping the liquid surface still;

[0060] 13) Start the fan assembly 4-11, start the tail gas treatment;

[0061] 3. Coating operation:

[0062] 1) After setting the coating speed, induction power input and other parameters in the operation system, one-key start the production line, that is, the servo motor 4-2-2 for pulling, the servo motor 4-2-8 for pre-bending rotation, the induction power system 3 and the belt traction speed measuring take-up device 5 all start to run;

[0063] 2) After the production line starts, the wire is continuously bent and sent into the coating tank 4-9, after being coated by the coating, it is sent out from the outlet of the coating tank 4-9, before entering the arc induction coil, the excess coating on the wire flows back to the coating tank under the action of gravity, at this time, the wire has been continuously coated with a uniform thickness lubricating coating, and enters the arc induction coil 3-2. Since the wire passes through the arc induction coil 3-2, an eddy current is formed inside the wire to heat the wire, and finally dry the uniform lubricating coating. After drying, it is sent out from the outlet of the arc induction coil 3-2 and enters the speed measuring guide roller assembly 4-10, at this time, the speed measuring guide roller assembly 4-10 can sense the offset position of the wire relative to the center of the arc induction coil 3-2 in real time. The actual effect is: if the wire offsets towards the arc center of the arc induction coil 3-2, the balance bar 4-10-3 of the speed measuring guide roller assembly 4-10 rotates counterclockwise around the central shaft 4-10-2, thereby increasing the displacement detected by the displacement sensor assembly 4-6 and feeding back to the system for response adjustment, the response result is to slow down the traction speed of the belt traction machine 5-1, and finally make the wire offset away from the arc center of the arc induction coil 3-2; on the contrary, if the wire offsets away from the arc center of the arc induction coil 3-2, the balance bar 4-10-3 of the speed measuring guide roller assembly 4-10 rotates clockwise around the central shaft 4-10-2, thereby reducing the displacement detected by the displacement sensor assembly 4-6 and feeding back to the system for response adjustment, the response result is to increase the traction speed of the belt traction machine 5-1, and finally make the wire offset towards the arc center of the arc induction coil 3-2. Such repeated oscillation adjustment makes the wire basically in the center of the arc induction coil 3-2 during the operation of the production line;

[0064] 3) The wire after coating and drying is repeatedly taken up and densely arranged on the I-shaped expanding and contracting wheel 5-2 of the belt traction speed measuring take-up device 5. The wire coated by the production line is dry and smooth, without falling off, air hole and vertical flow scar phenomenon, and the coating has the characteristics of uniform thickness, tight combination and strong adhesion after detection;

[0065] After the coating and take-up are completed, the production line stops running, the coated and wound wire is packed, the diameter of the I-shaped expanding and contracting wheel 5-2 is reduced, and then the wire is taken off, and thus the whole process of the production line is completed.
