[0003] During the production process of stainless steel wire, in order to achieve the required diameter, it needs to be stretched through multiple dies with gradually decreasing diameters. However, during the stretching process of the stainless steel wire through the die, due to insufficient lubrication, the surface of the stainless steel wire is usually worn, and the service life of the die is short. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel wire lubricating device and process for avoiding die wear in order to solve the problems of thin lubricating film layer on the surface of existing steel wires, resulting in die wear, decline in steel wire performance, surface scratches, and wire breakage.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme: A steel wire lubricating device for avoiding die wear, which includes:

[0006] A wire pay-off stand, a lubricating mechanism, an electrostatic spraying mechanism, and a winding roller arranged in sequence; wherein,

[0007] The lubricating mechanism includes an oil storage tank and a lubricating roller, and the lubricating roller is rotatably connected in the oil storage tank;

[0008] The electrostatic spraying mechanism includes two spraying components and a turning component. The turning component is located between the two spraying components. The spraying component includes a material tank, a spray gun, a negative electrode plate, and a positive electrode plate. The spray gun is arranged at the discharge port of the material tank, the spray gun is vertically downward and directly faces the steel wire, the negative electrode plate is arranged at the nozzle of the spray gun, the positive electrode plate is located below the negative electrode plate, and the positive electrode plate is grounded.

[0009] As a further description of the above technical scheme:

[0010] A dispersing component is arranged at the bottom of the material tank, and the spray gun is arranged at the discharge port of the dispersing component.

[0011] As a further description of the above technical scheme:

[0012] The crushing component includes a housing, a drum and a screen. The housing is connected to the discharge port of the feed bin. The drum is rotatably connected inside the housing. A number of cylinders are evenly arranged on the surface of the drum. The screen is arranged at the bottom of the drum.

[0013] As a further description of the above technical solution:

[0014] The screen includes an upper screen and a lower screen, and the upper screen and the lower screen are arranged in a staggered manner.

[0015] As a further description of the above technical solution:

[0016] The spraying component further includes a sealing shell and a dust suction pipe. The feed bin, the spray gun, the negative electrode plate and the positive electrode plate are all located inside the sealing shell. The dust suction pipe is fixedly connected inside the sealing shell and is located on one side of the spray gun.

[0017] As a further description of the above technical solution:

[0018] The steering component includes two guide rollers arranged in parallel.

[0019] As a further description of the above technical solution:

[0020] The lubricating roller is arranged on the driving shaft of the motor, and a lubricating rubber sleeve is arranged on the lubricating roller.

[0021] As a further description of the above technical solution:

[0022] A guide wheel is arranged on one side of the oil storage tank.

[0023] The present invention discloses a lubrication process for a wire lubrication device to avoid die wear, which includes the following steps:

[0024] S1: The wire is drawn out from the wire pay-off stand, and then passes through the lubrication mechanism, the electrostatic spraying mechanism and the wire drawing die in sequence and is connected to the winding roller.

[0025] S2: When the wire passes through the lubrication mechanism, the motor drives the lubricating roller to rotate. The lubricating rubber sleeve can soak the lubricating liquid in the oil storage tank and apply the lubricating liquid on the wire.

[0026] S3: When the wire coated with the lubricating liquid passes through the electrostatic spraying mechanism, the lubricating powder falls into the housing from the feed bin, is crushed again by the drum, flows out from the screen and is sprayed out by the spray gun. The negative electrode plate installed at the nozzle of the spray gun and the grounded positive electrode plate work simultaneously to form a high-voltage electric field. Under the action of the high-voltage air flow and the high-voltage electric field, the lubricating powder is adsorbed on the surface of the wire, and the lubricating powder gradually covers the surface of the wire to form a lubricating film layer with a certain thickness.

[0027] S4: The steel wire attached with lubricating fluid and lubricating powder is drawn through a wire drawing die to obtain a finished product, and finally wound by a winding roller.

[0028] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0029] 1. In the present invention, through the set lubricating mechanism, when the steel wire passes through the lubricating mechanism, a lubricating film can be formed on the steel wire. Then, when the steel wire passes through the electrostatic spraying mechanism, another lubricating film can be formed on the steel wire, so that two lubricating films can be formed on the steel wire, which can effectively reduce the friction coefficient, reduce the heat generation degree of the steel wire and the die, improve the die life, the performance and surface quality of the steel wire, and further improve the product quality and precision, improve the production efficiency, and reduce the product production cost.

[0030] 2. In the present invention, the motor drives the lubricating roller to rotate in the oil storage tank, so as to facilitate the lubricating rubber sleeve to soak the lubricating fluid. The upper surface of the lubricating rubber sleeve located above the lubricating fluid contacts the steel wire, which can prevent the steel wire from sticking with excess lubricating fluid. In this way, the lubricating rubber sleeve can efficiently apply the lubricating oil in the oil storage tank evenly on the steel wire.

[0031] 3. In the present invention, the lubricating powder falls from the material box into the shell, is dispersed again through the roller, flows out from the sieve and is sprayed out by the spray gun. The negative electrode plate installed at the nozzle of the spray gun and the grounded positive electrode plate work simultaneously to form a high-voltage electric field. Under the action of the high-voltage air flow and the high-voltage electric field, the lubricating powder is adsorbed on the surface of the steel wire. As the lubricating powder gradually covers the surface of the steel wire to form a lubricating film layer with a certain thickness, when the lubricating powder gradually covers the surface of the steel wire to form a coating with a certain thickness, the charges will repel each other, and the lubricating powder will no longer be adsorbed and accumulated continuously, so that a lubricating film layer with a uniform thickness is formed on the surface of the steel wire.

The spraying component 31 includes a material box 311, a spray gun 312, a negative electrode plate 313 and a positive electrode plate 314. The spray gun 312 is arranged at the discharge port of the material box 311, the spray gun 312 is vertically downward and directly faces the wire, the negative electrode plate 313 is arranged at the nozzle of the spray gun 312, the positive electrode plate 314 is located below the negative electrode plate 313, and the positive electrode plate 314 is grounded.

[0044] A dispersion component 5 is provided at the bottom of the material box 311, and the spray gun 312 is provided at the discharge port of the dispersion component 5. The dispersion component 5 includes a housing 51, a drum 52 and a screen 53. The housing 51 is connected to the discharge port of the material box 311. The drum 52 is rotatably connected within the housing 51. A number of cylinders are evenly arranged on the surface of the drum 52. The screen 53 is provided at the bottom of the drum 52. During use, when the lubricating powder falls from the material box into the housing and lands on the drum, the drum rotates. Specifically, the drum is driven to rotate by a motor. The cylinders on the drum disperse the falling lubricating powder. After passing through the screen, it enters the spray gun, thereby achieving the best electrostatic spraying effect.

[0045] The screen 53 includes an upper screen 531 and a lower screen 532, and the upper screen 531 and the lower screen 532 are arranged in a staggered manner. It can disperse the lubricating powder in a staggered manner, enabling the powder to be thoroughly dispersed.

[0046] The spraying component 31 further includes a sealing shell 315 and a dust suction pipe 316. The material box 311, the spray gun 312, the negative electrode plate 313 and the positive electrode plate 314 are all located within the sealing shell 315. The dust suction pipe 316 is fixedly connected within the sealing shell 315, and the dust suction pipe 316 is located on one side of the spray gun 312. The dust suction pipe is connected to a vacuum cleaner, which can suck away the excess lubricating powder to prevent the lubricating powder from remaining on the steel wire and affecting wire drawing.

[0047] The steering component 32 includes two guide rollers arranged in parallel. The guide rollers are used to change the steel wire from being face-up to being back-up during the conveying process, so that it can be sprayed again by the subsequent spraying component.

[0048] The lubricating roller 22 is provided on the drive shaft of the motor 6, and a lubricating rubber sleeve 7 is provided on the lubricating roller 22. A guide wheel 8 is provided on one side of the oil storage tank 21. The lubricating rubber sleeve can efficiently apply the lubricating oil in the oil storage tank evenly onto the steel wire.

[0049] The lubrication process of a steel wire lubricating device for avoiding die wear includes the following steps:

[0050] S1: The steel wire is drawn out from the wire pay-off rack 1, and then passes through the lubrication mechanism 2, the electrostatic spraying mechanism 3 and the wire drawing die in sequence and is connected to the take-up roller 4;

[0051] S2: When the steel wire passes through the lubrication mechanism, the motor drives the lubricating roller 22 to rotate. The lubricating rubber sleeve can soak the lubricating liquid in the oil storage tank and apply the lubricating liquid onto the steel wire;

[0052] S3: When the steel wire coated with lubricant enters the electrostatic spraying mechanism 3, the lubricating powder drops from the feed hopper 311 into the housing. After being dispersed again by the drum, it flows out from the sieve and is sprayed out by the spray gun. The negative electrode plate 313 installed at the nozzle of the spray gun and the grounded positive electrode plate 314 work simultaneously to form a high-voltage electric field. Under the action of the high-pressure air flow and the high-voltage electric field, the lubricating powder is adsorbed on the surface of the steel wire, and the lubricating powder gradually covers the surface of the steel wire to form a lubricating film layer with a certain thickness.

[0053] S4: The steel wire attached with lubricant and lubricating powder enters the wire drawing die for drawing to obtain the finished product, and finally is wound by the winding roller 4.

[0054] Working principle: The steel wire is drawn out from the wire pay-off rack 1 and then passes through the lubricating mechanism 2, the electrostatic spraying mechanism 3 and the wire drawing die in sequence and is connected to the winding roller 4. The motor drives the lubricating roller to rotate in the oil storage tank, so that it is convenient for the lubricating rubber sleeve to be immersed in the lubricant. The upper surface of the lubricating rubber sleeve located above the lubricant contacts the steel wire, which can prevent the steel wire from sticking with excessive lubricant. In this way, the lubricating rubber sleeve can efficiently apply the lubricating oil in the oil storage tank evenly on the steel wire. The lubricating powder drops from the feed hopper into the housing. After being dispersed again by the drum, it flows out from the sieve and is sprayed out by the spray gun. The negative electrode plate installed at the nozzle of the spray gun and the grounded positive electrode plate work simultaneously to form a high-voltage electric field. Under the action of the high-pressure air flow and the high-voltage electric field, the lubricating powder is adsorbed on the surface of the steel wire, and the lubricating powder gradually covers the surface of the steel wire to form a lubricating film layer with a certain thickness. After the lubricating powder gradually covers the surface of the steel wire to form a coating with a certain thickness, charge repulsion will occur, and the lubricating powder will no longer be adsorbed and accumulated continuously, so that a lubricating film layer with a uniform thickness is formed on the surface of the steel wire. In the present invention, through the provided lubricating mechanism, when the steel wire passes through the lubricating mechanism, a lubricating film can be formed on the steel wire. Then when the steel wire passes through the electrostatic spraying mechanism, a lubricating film can be formed on the steel wire again. Thus, two lubricating films can be formed on the steel wire, which can effectively reduce the friction coefficient, reduce the heat generation degree of the steel wire and the die, improve the die life, the performance and the surface quality of the steel wire, and further improve the product quality and precision, improve the production efficiency and reduce the product production cost.
