Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel wire production equipment, in particular to a steel wire coating device. Background Art
[0002] Steel strand is a steel product composed of multiple steel wires twisted together. The surface of the steel strand can be coated with galvanized layer, zinc-aluminum alloy layer, aluminum layer, copper plating layer, epoxy resin coating, etc. as needed. The specific production process is: pickling and phosphating the wire rod as the mother bar, dry drawing the phosphated mother bar to obtain the intermediate steel wire, twisting the intermediate steel wire into prestressed steel strand, and stabilizing the twisted steel strand to obtain the finished product.
[0003] Phosphate coating refers to the production of a phosphate film on the surface of the wire rod to increase the lubrication performance of the wire rod surface during the production process to protect the surface quality of the steel wire. During the phosphating process, the water temperature of the phosphating pool is strictly required and must be guaranteed to be between 70℃-80℃, so that the surface quality of the wire rod can be the best. The existing technology is to set a heating element in the phosphating pool to heat the water temperature of the phosphating pool, for example, the reference prestressed steel strand non-acid washing phosphating device-CN 212640608 U, which is heated by an electric heating plate; a steel strand phosphating device-CN217536159U, which is heated by heating oil.
[0004] Although the water temperature of the phosphating bath is kept in a suitable temperature range by heating in the prior art, the phosphating solution and the steel wire are in contact with each other and cooled down due to the low temperature when the steel wire enters the phosphating bath, so the phosphating effect cannot be guaranteed. Utility Model Content
[0005] The utility model aims to provide a steel wire coating device to solve the problem in the prior art that the temperature of the steel wire when entering the phosphating bath is low, resulting in poor phosphating effect.
[0006] In order to achieve the above object, the utility model provides the following technical solutions:
[0007] A steel wire coating device comprises a phosphating tank, a heating chamber is provided at the bottom of the phosphating tank, and a heating element is provided in the heating chamber; and a connecting frame is arranged at the top of the phosphating tank, and the connecting frame is provided with a guide roller extending into the phosphating tank, and the connecting frame is provided with a first heating mechanism and a second heating mechanism on both sides of the guide roller, respectively, the first heating mechanism comprises a heating cylinder, and a heating wire is provided inside the heating cylinder, and the second heating mechanism comprises a blower cylinder with a hollow interior, and the blower cylinder is connected to a hot air pipe, and one end of the blower cylinder is connected to a plurality of blowing holes facing the phosphating tank along its circumferential direction.
[0008] The working principle and beneficial effects of the utility model are as follows: a heating chamber is provided at the bottom of the phosphating tank, which separates the heating element and the phosphating tank, and the heating element heats the phosphating liquid in the phosphating tank. The steel wire passes through the heating cylinder, the guide roller and the blower in sequence and then extends out, and the steel wire extends into the phosphating liquid at the guide roller. The heating cylinder is heated by the heating wire, and the steel wire is also heated and heated when passing through the heating cylinder, and the heated steel wire immediately enters the phosphating tank; when the steel wire is separated from the phosphating liquid, the hot air pipe blows hot air into the blower, and one end of the blower is connected to a plurality of blowing holes facing the phosphating tank along its circumferential direction. The hot air passes through the plurality of blowing holes and blows toward the steel wire, and the hot air continues to heat the steel wire, and blows the excess phosphating liquid on the steel wire into the phosphating tank.
[0009] The present application first heats the steel wire through a heating cylinder so that the surface of the steel wire is heated to a suitable phosphating temperature. After the steel wire enters the phosphating tank, the phosphating liquid will not be cooled, causing the temperature of the phosphating liquid to drop, and the high surface temperature of the steel wire is conducive to the phosphating liquid entering the interior of the steel wire for phosphating; at the same time, after the steel wire is separated from the phosphating liquid, hot air is blown to the steel wire through multiple blowing holes, and the hot air continues to heat the steel wire, which can prevent the phosphating liquid on the surface of the steel wire from cooling down quickly in the air, thereby prolonging the phosphating time of the steel wire by the phosphating liquid, thereby improving the phosphating effect.
[0010] Furthermore, the connecting frame is provided with traction rollers located on both sides of the guide roller, and the traction rollers and the guide rollers on both sides are arranged in a triangle in space. Such an arrangement can smoothly pull the steel wire into the phosphating tank for phosphating coating.
[0011] Furthermore, the number of the blowing holes is 8 to 12, and they are evenly spaced along the circumferential direction of the blowing cylinder. The steel wire is heated by blowing through the 8 to 12 blowing holes, and the heating effect is better.
[0012] Furthermore, the axes of the heating cylinder and the blowing cylinder are both inclined toward the bottom of the phosphating tank, so that the heating of the steel wire is more uniform.
[0013] Furthermore, a stirring shaft is rotatably connected to the bottom of the phosphating tank, and the stirring shaft is provided with spiral blades. The stirring shaft drives the spiral blades to rotate to stir the phosphating solution, thereby increasing the heating speed of the phosphating solution.
[0014] Furthermore, the diameter of the blowing hole is 5 to 10 mm, so that the steel wire can be blown more easily. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The connecting frame 4 is located on both sides of the guide roller 1 and is fixedly provided with a first heating mechanism and a second heating mechanism. The first heating mechanism includes a heating cylinder 2. The heating cylinder 2 is fixedly connected to a support rod 14. The support rod 14 and the connecting frame 4 are fixedly connected.
[0023] A heating wire 12 is fixedly disposed inside the heating tube 2; Figure 3 As shown, the second heating mechanism includes a blow tube 7 with a hollow interior, the blow tube 7 is connected to and fixed with a hot air pipe 5, the hot air pipe 5 passes through the connecting frame 4 and is fixedly connected, and the end face of one end of the blow tube 7 is connected to two blowing holes 13 facing the phosphating tank 6 along its circumferential direction.

The heating rod 9 heats the phosphating solution in the phosphating pool 6. The steel wire 10 passes through the traction roller 3, the heating cylinder 2, the guide roller 1 and the blowing cylinder 7 in sequence and then extends out. The steel wire 10 extends into the phosphating solution at the guide roller 1. The heating cylinder 2 is heated by the heating wire 12, so the steel wire 10 is also heated and heated when passing through the heating cylinder 2.

After the steel wire 10 enters the phosphating pool 6, the phosphating liquid will not be cooled, causing the temperature of the phosphating liquid to decrease, and the high surface temperature of the steel wire 10 is conducive to the phosphating liquid entering the steel wire 10 for phosphating; at the same time, after the steel wire 10 is separated from the phosphating liquid, the hot air passes through the two blowing holes 13 and blows toward the steel wire 10, and the hot air continues to heat the steel wire 10, which can prevent the phosphating liquid on the surface of the steel wire 10 from cooling down quickly in the air, thereby prolonging the phosphating time of the steel wire 10 by the phosphating liquid, so as to improve the phosphating effect.
