Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip plating, in particular to a wire hot-dip plating mechanism. Background Art

[0002] In industrial production, it is necessary to cover the surface of various metal wires with another metal coating to achieve purposes such as anti-corrosion and easy welding. A relatively common method is to immerse the wire in molten coating metal, which is called hot-dip plating. For wires with a very long length, it is necessary to use hot-dip plating equipment to continuously hot-dip the wire.

[0003] In the prior art, a structure of a guide wheel immersed in the coating metal melt is mostly adopted. A guide wheel is added during the conveying process of the wire, and the wire is forced to turn and pass through the coating metal melt. The following defects mainly exist:

[0004] 1. Fine impurities (dust in the environment, attachments dropped due to the extrusion of the guide wheel and the wire, etc.) will be introduced before the wire enters the melt. Under the pressure of the guide wheel, they will adhere to the wire and be wrapped by the coating, affecting the product quality.

[0005] 2. The wire needs to bear more traction force to drive the guide wheel to rotate, increasing the risk of wire breakage for thinner and lower-strength wires. Once the wire breaks, a whole roll of finished products and production time will be lost.

[0006] Therefore, it is necessary to design a wire hot-dip plating mechanism. Content of the Utility Model

[0007] Aiming at the defects in the prior art, the utility model provides a wire hot-dip plating mechanism.

[0008] The technical solution adopted by the utility model is: a wire hot-dip plating mechanism, including a furnace cage and a furnace liner installed on the furnace cage. A furnace body shell is arranged on the outer side of the furnace cage; hollow rotating shafts are arranged on the outer sides of both ends of the furnace cage, and a wire inlet and outlet assembly located at the center of the hollow rotating shaft is arranged on the furnace cage. An installation base matching with the wire inlet and outlet assembly is arranged on the inner side of the furnace liner.

[0009] To better implement the utility model, a plurality of heating sleeves are arranged between both ends of the furnace liner, and electric heating tubes are arranged in each heating sleeve.

[0010] To better implement the utility model, a heat preservation space is formed between the furnace body shell and the furnace liner, and heat preservation materials are filled in the heat preservation space.

[0011] To better implement the utility model, the furnace cage includes two furnace cage end plates, and a plurality of furnace cage beams are connected between the two furnace cage end plates. The furnace liner is placed on the furnace cage beams.

[0012] To better implement the present utility model, a plurality of furnace liner supports are provided on both the furnace cage end plate and the furnace cage beam, and the furnace liner is in contact with the furnace liner supports.

[0013] To better implement the present utility model, the wire inlet and outlet assembly includes a wire passing nozzle installed on the installation base.

[0014] To better implement the present utility model, an air chamber is installed on the installation base, the wire passing nozzle is arranged on the air chamber, and an air connector for blowing air inward is arranged on the air chamber.

[0015] To better implement the present utility model, a lifting ear is detachably installed on the outer side of the furnace cage end plate.

[0016] The beneficial effects of the present utility model are as follows: The wire hot-dip plating mechanism of the present utility model, through the cooperation of the furnace cage, the furnace liner, the furnace body shell, the hollow rotating shaft, the wire inlet and outlet assembly, and the installation base, etc., when in use, the wire passes through the wire inlet and outlet assembly for hot-dip plating. The furnace body shell can cooperate with the flipping mechanism. When the flipping mechanism flips, the liquid level of the hot-dip plating metal liquid in the furnace liner changes. When the liquid level is higher than the height of the wire, hot-dip plating operation can be carried out. When the liquid level is lower than the height of the wire, the hot-dip plating stops. At this time, operations such as replenishing the hot-dip plating metal liquid, replacing the wire, and replacing the wire inlet and outlet assembly can be carried out. Compared with the prior art of using guide wheels to forcibly change the direction of the wire and immerse it in the hot-dip plating metal liquid, no slag will be introduced, no excessive pressure will be applied to the wire, the risk of product damage is reduced, and the product quality can be greatly improved.

A furnace body shell 3 is arranged outside the furnace cage 5; hollow rotating shafts 6 are arranged on the outer sides of both ends of the furnace cage 5, and a wire inlet and outlet assembly 7 located at the center of the hollow rotating shafts 6 is arranged on the furnace cage 5. An installation base 10 cooperating with the wire inlet and outlet assembly 7 is arranged inside the furnace liner 4. The wire hot-dip plating mechanism of the present utility model, through the cooperation of the furnace cage 5, the furnace liner 4, the furnace body shell 3, the hollow rotating shafts 6, the wire inlet and outlet assembly 7, and the installation base 10, etc., when in use, allows the wire 9 to pass through the wire inlet and outlet assembly 7 for hot-dip plating. The furnace body shell 3 can cooperate with a flipping mechanism. When the flipping mechanism flips, the liquid level of the hot-dip plating metal liquid 23 in the furnace liner 4 changes. When the liquid level is higher than the height of the wire 9, hot-dip plating operations can be carried out. When the liquid level is lower than the height of the wire 9, the hot-dip plating stops. At this time, operations such as replenishing the hot-dip plating metal liquid 23, replacing the wire 9, and replacing the wire inlet and outlet assembly 7 can be carried out. Compared with the prior art where guide wheels are used to forcibly change the direction of the wire 9 and immerse it in the hot-dip plating metal liquid 23, no slag will be introduced, no excessive pressure will be exerted on the wire 9, the risk of product damage is reduced, and the product quality can be greatly improved.

[0033] As a preferred embodiment, a plurality of heating sleeves 14 are arranged between the two ends of the furnace liner 4, and electric heating tubes 12 are arranged inside each heating sleeve 14. After such a design, when the electric heating tubes 12 are energized for heating, the heat is transferred to the hot-dip plating metal liquid 23 through the heating sleeves 14 to keep it in a liquid state continuously, facilitating the hot-dip plating operation. The heating tubes 12 do not come into direct contact with the hot-dip plating metal liquid 23, which can improve the service life of the heating tubes 12 and is also convenient for disassembly and replacement.

[0034] As a preferred embodiment, a heat preservation space 13 is formed between the furnace body shell 3 and the furnace liner 4. Heat preservation materials are filled in the heat preservation space 13, which can play a role in heat preservation, reduce heat loss, and also play a role in preventing scalding. The heat preservation materials can be materials such as asbestos and glass fiber.

[0035] As a preferred embodiment, the furnace cage 5 includes two furnace cage end plates 15. A plurality of furnace cage beams 16 are connected between the two furnace cage end plates 15, and the furnace liner 4 is placed on the furnace cage beams 16.

After such a design, the furnace liner 4 can be conveniently carried. It should be noted that some of the furnace cage beams 16 located at the top can be set to be movably installed, which is convenient for the installation of the furnace liner 4. The setting of the furnace liner supports 17 can conveniently press against the furnace liner 4 and improve the stability.

[0036] As a preferred embodiment, the wire inlet and outlet assembly 7 includes a wire passing nozzle 20 installed on the installation base 10 for the wire 9 to pass through.

After such a design, the air joint 19 is connected to a gas source and continuously blows air into the air chamber 18. On the one hand, it can give a certain pressure to the hot-dip metal liquid 23 to prevent the hot-dip metal liquid 23 from flowing out of the wire passing nozzle 20 along with the wire 9. On the other hand, it also plays a role in rapid cooling, enabling the wire 9 after hot-dip plating to be rapidly cooled.

[0038] As a preferred embodiment, a lifting ear 11 is detachably installed on the outer side of the furnace cage end plate 15. The lifting ear 11 can be detachably installed on the outer side of the furnace cage 5. When the lifting ear 11 faces upward, it can be used for lifting. When the lifting ear 11 faces downward, it can be used to block the end of the movably installed furnace cage beam 16 and play a stabilizing role.
