Description

Technical Field

[0001] The utility model relates to the field of wire heat treatment equipment, in particular to a salt bath wire anti-rust treatment device. Background Art

[0002] Salt bath treatment is a common strengthening treatment method for high-carbon steel wires. In salt bath treatment, hot-rolled high-carbon steel wires are processed on a salt bath production line through wire feeding, high-temperature heating, isothermal salt bath, cleaning, and wire winding to produce wires with good strength and plasticity for downstream users to draw. Inevitably, there is a small amount of residual salt on the surface of the salt bath wires after cleaning. Due to the absorption of moisture and deliquescence of the surface salt, a liquid film with electrolytes is formed, and the salt bath wires are more likely to rust on the surface compared with hot-rolled wires. Therefore, adding an anti-rust treatment after cleaning is very important for ensuring the storage of salt bath wires.

[0003] To ensure production efficiency, 10 to 20 wires need to be processed simultaneously in salt bath treatment. Due to the space limitation of the production line, the distance between the wires is less than 10 cm. Therefore, the anti-rust treatment device needs to ensure a compact structure and be able to process multiple wires simultaneously.

[0004] Currently, on-line oil coating / oil spraying treatment is commonly used for wire anti-rust. For example, the Chinese utility model patent with the publication number CN 217796827 U discloses "a wire anti-rust oil spraying device for high-speed wire rolling", which uses an oil spraying box to realize the cleaning and oil spraying treatment of the wire surface. However, it is used to process a single wire and has a relatively complex structure, and is not suitable for anti-rust treatment of a large number of wires simultaneously.

[0005] For example, the Chinese utility model patent with the publication number CN 219051840 U discloses "an on-line wire oil coating device", which uses an oil coating cloth to perform the oil coating operation on the metal wire. Its structure is compact, but it has high requirements for the lateral positioning of the wire. During the continuous production process of the wire, there are inevitably phenomena such as deviation and bending in the forward direction. If the lateral position is restricted by guide wheels, additional mechanical structures need to be added, and the risk of wire scratching is increased. Summary of the Invention

[0006] The purpose of the utility model is to provide a salt bath wire anti-rust treatment device to solve the problems that the mechanical structure of the wire anti-rust treatment device in the above background is complex and it is impossible to perform anti-rust treatment on a large number of wires simultaneously.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A rust prevention treatment device for salt bath wire, comprising a rust prevention oil spraying pipe and a rust prevention oil collecting tank. The rust prevention oil spraying pipe is arranged above along the direction perpendicular to the movement direction of the wire, and the rust prevention oil collecting tank is arranged below the spraying pipe. An oil outlet pipe is provided on the side of the rust prevention oil collecting tank and is connected to a circulation pump, and an oil inlet pipe is provided in the middle of the rust prevention oil spraying pipe and is connected to the circulation pump. The rust prevention oil collecting tank, the oil outlet pipe, the circulation pump, the oil inlet pipe, and the rust prevention oil spraying pipe together form a rust prevention oil circulation loop.

[0009] Further, the above-mentioned rust prevention oil spraying pipe is a cylindrical pipe, and a spraying tank for spraying the rust prevention oil is provided at the bottom, and a pressing mechanism including an eccentric wheel, a handle on the eccentric wheel, a pressing rod support frame, a pressing rod, and a spring is provided above.

[0010] Further, the upper part of the pressing rod is connected to the eccentric wheel through a shaft hole, the pressing rod passes through a through hole at the top of the rust prevention oil spraying pipe, sealing flanges are respectively provided on both sides of the middle part of the pressing rod above and below the through hole, the sealing flange is in contact with the spring above, and an arc-shaped sealing gate is fixed at the bottom of the pressing rod.

[0011] Further, a sealing groove and a sealing ring are provided around the through hole above the rust prevention oil spraying pipe, and a rubber coating is provided at the bottom of the sealing gate.

[0012] Through the above technical solution, the rust prevention oil spraying pipe can be effectively sealed.

[0013] Further, the bottom of the rust prevention oil collecting tank is a V-shaped inclined plane, and the oil outlet is arranged in the middle of the rust prevention oil collecting tank, and a filter screen is provided at the oil outlet.

[0014] Through the above technical solution, the suspended particles in the rust prevention oil can be promoted to deposit at the bottom of the tank, which is convenient for collection and cleaning, and reduces the particulate matter from entering the circulation loop.

[0015] Further, multiple groups of spraying tanks and corresponding pressing rods are arranged horizontally on the rust prevention oil spraying pipe.

[0016] Through the above technical solution, selective spraying of rust prevention oil on the wire can be realized, and each group of rust prevention oil spraying tanks can cover an area.

[0017] The rust prevention treatment device for salt bath wire of the present utility model has the following beneficial effects:

[0018] 1. By arranging multiple groups of spraying tanks on a rust prevention oil spraying pipe, rust prevention treatment can be simultaneously carried out on a large number of closely arranged wires, and there is a certain tolerance for the lateral position of the wires, and it can be arranged in the middle section of the production line, making full use of the wire guiding mechanism of the production line and avoiding adding redundant guiding structures.

[0019] 2. Through a simply designed pressing and sealing mechanism, selective and effective sealing of multiple groups of rust prevention oil spraying pipes can be realized.

[0020] 3. By means of an anti-rust oil tank with a V-shaped ramp bottom surface and an oil outlet with a filter screen, the entry of sediments into the anti-rust oil circulation circuit is reduced. Brief Description of the Drawings

Detailed Embodiment

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] In this specification, the scale of the drawings does not represent the actual scale. It is only used to reflect the relative positional relationship and connection relationship between components. Components with the same name or the same reference numeral represent similar or identical structures, and are for illustrative purposes only.

[0028] The present utility model provides a technical solution: a salt bath wire anti-rust treatment device, as Figure 1 and Figure 2As shown in the figure, the antirust oil spraying pipe 1 is arranged above along the direction perpendicular to the movement direction of the wire 2, and the antirust oil collecting tank 3 is arranged below the spraying pipe. An oil outlet pipe 5 is provided in the middle of the side of the antirust oil collecting tank 3, and an oil inlet pipe 7 is in the middle of the antirust oil spraying pipe 1. The circulation pump 6 is arranged on the side of the antirust oil collecting tank 3. The antirust oil spraying pipe 1 is a cylindrical pipe, and a spraying groove 18 for spraying antirust oil is provided at the bottom, and a pressing mechanism including an eccentric wheel 10, a handle 9 on the eccentric wheel, a pressing rod support frame 11, a pressing rod 16, and a spring 12 is provided above. The antirust oil collecting tank 3, the oil outlet pipe 5, the circulation pump 6, the oil inlet pipe 7, and the antirust oil spraying pipe 1 together constitute an antirust oil circulation loop. During use, the salt-bath wire 2 continuously passes below the antirust oil spraying pipe 1. The antirust oil enters the circulation pump 6 through the oil outlet pipe 5, and then is transported to the antirust oil spraying pipe 1 through the oil inlet pipe 7, and then evenly sprayed onto the surface of the wire through the antirust oil spraying groove 18 to form a corrosion-inhibiting protective film, delaying the corrosion of the salt-bath wire.

[0029] As Figure 2 shown in the figure, there is a pressing rod 16 in the middle of the antirust oil spraying pipe. The upper part of the pressing rod 16 is connected to the eccentric wheel 10 through a shaft hole. The pressing rod 16 passes through the through hole at the top of the antirust oil spraying pipe 1. Sealing flanges 13 are respectively arranged on both sides of the through hole above and below the middle of the pressing rod 16. The upper part of the sealing flange 13 is in contact with the spring 12, and an arc-shaped sealing gate plate 17 is fixed at the bottom of the pressing rod 16. A sealing ring 14 is arranged around the through hole above the antirust oil spraying pipe 1, and a rubber coating is arranged at the bottom of the sealing gate plate 17. During the use process, when the handle 9 is rotated to the left, the eccentric wheel 10 rotates to drive the pressing rod 16 to rise to the highest position, the spring 12 is compressed, the second sealing flange 132 is pressed against the second sealing ring 142 beside the through hole, and a gap for the antirust oil to pass through is formed between the sealing gate plate 17 and the antirust oil spraying groove 18. On the contrary, when the handle is rotated to the right, the pressing rod 16 descends to the lowest position, the spring 12 rebounds, the first sealing flange 131 is pressed against the first sealing ring 141, and the sealing gate plate 17 is pressed against the antirust oil spraying groove 18 to block the outflow of the antirust oil, realizing effective sealing.

[0030] As Figure 3 shown in the figure, multiple groups of spraying grooves 18 and corresponding pressing rods 16 are arranged horizontally on the antirust oil spraying pipe 1. During the use process, if there is no wire 2 passing below the spraying groove 18, the handle 9 can be rotated to lower the pressing rod 16 to close the spraying groove 18, reducing the waste of antirust oil. Since the spraying groove 18 can cover a certain width horizontally, the wire 2 is allowed to swing within a certain range without affecting the antirust treatment.

[0031] As Figure 1As shown, the bottom of the rust preventive oil collection tank 3 is a V-shaped inclined plane. During the rust prevention process, the rust preventive oil is sprayed from the rust preventive oil spraying pipe 1, falls on the surface of the wire 2, and then falls into the rust preventive oil collection tank 3. The V-shaped inclined plane at the bottom of the tank plays a role in promoting the deposition and aggregation of particulate matters, facilitating collection and cleaning. The oil outlet pipe 5 is arranged in the middle of the rust preventive oil collection tank 3, and a filter screen 4 is arranged on the oil outlet pipe 5 to reduce the sediment entering the circulation loop.

[0032] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
