Description

Technical Field

[0001] The utility model belongs to the technical field of pickling tanks, and in particular relates to a pickling tank anti-twisting line device. Background Art

[0002] A pickling tank is a container used to hold aqueous solution during the pickling process to remove the metal surface film. It is generally used in production workshops and is durable, convenient, and has a large workload.

[0003] Since the steel wire itself has the characteristic of linear jump, an anti-twisting device is generally provided to prevent the steel wire from escaping from the pickling tank due to jump during pickling. The anti-twisting device currently used in the market is a single hollow plastic roller without a fixed material, which is simply placed on the steel wire. However, the steel wire with relatively large jumps can easily lift up the hollow roller, jump out of the original groove, and enter the adjacent groove, causing the two steel wires to advance in one groove, causing scratches on the surface of the steel wire, and easily causing the annealing furnace to have a constant force inconsistent before and after the two steel wires are tangled together, causing the steel wire to shrink in diameter. In view of the above situation, in the prior art, workers generally open the pickling tank cover intermittently and hook the steel wire back to its original position with an iron hook, but the acid in the pickling tank has a strong irritating odor, which can cause discomfort to the human body. Summary of the invention

[0004] The utility model aims to provide a pickling tank anti-tangling wire device, which can ensure that the stainless steel wire cannot jump out of the pickling tank and will not cause the stainless steel wire to be tangled together, avoid the disadvantages caused by the workers frequently opening the pickling tank cover in the prior art, and reduce the labor intensity.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: a pickling tank anti-wire tampering device, the anti-wire tampering device is vertically arranged in the pickling tank steel wire feeding direction, the anti-wire tampering device includes fixed blocks fixedly welded on both sides of the inner wall of the pickling tank, the upper end of the fixed block is provided with a through hole along the width direction of the fixed block, a screw passes through the through hole, and the screw is connected to the fixed block via a nut; the upper end of the fixed block is also provided with a U-shaped groove connected with the through hole, a solid plastic roller is provided above the bottom end of the U-shaped groove and is located below the screw, and the bottom end point of the U-shaped groove is higher than the surface of the steel wire.

[0006] Among them, the steel wire is stainless steel wire.

[0007] Preferably, there are several anti-twisting devices, and the several anti-twisting devices are arranged in parallel and perpendicular to the direction in which the steel wire enters the pickling tank.

[0008] More preferably, the number of the anti-wire twisting devices is 3.

[0009] Preferably, the screw is connected to the fixing block via a nut to form an upper limit position, the bottom end of the U-shaped groove is a lower limit position, and the solid plastic roller moves up and down between the upper limit position and the lower limit position.

[0010] Preferably, the fixing block is a plastic fixing block.

[0011] Preferably, the screw is a plastic screw, and the nut is a plastic nut.

[0012] More preferably, the plastic screw is a plastic fiber screw M8×60, and the plastic nut is a plastic limit nut M8.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] The pickling tank anti-tangle wire device of the present invention can ensure that the stainless steel wire does not jump out of the pickling tank, and will not cause the stainless steel wire to be tangled together, thereby avoiding the disadvantages caused by workers frequently opening the pickling tank cover in the prior art, and reducing labor intensity. Among them, a through hole is provided at the upper end of the fixed block along the width direction of the fixed block, and a screw is passed through the through hole. The screw is connected to the fixed block through a nut to form an upper limit. A U-shaped groove connected to the through hole is also provided at the upper end of the fixed block. A solid plastic roller is provided above the bottom end (lower limit) of the U-shaped groove and is located below the upper limit. The solid plastic roller moves up and down between the upper limit and the lower limit, so that the jumping stainless steel wire in the pickling tank is buffered and part of the impact force is unloaded. When the solid plastic roller is in the lowest position, its lowest surface is also higher than the surface of the steel wire. The stainless steel wire that moves forward normally without jumping will not contact the solid plastic roller, thereby avoiding the disadvantage that the hollow pressure roller in the prior art is always in contact with the stainless steel wire and presses on the surface of the steel wire, which will cause bending of the thin steel wire.

DETAILED DESCRIPTION

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-5 As shown, a pickling tank anti-twisting device, the anti-twisting device 1 is vertically arranged in the pickling tank 2 in the direction of the steel wire 3 entering the wire, specifically: the number of the anti-twisting devices 1 is three, and the three anti-twisting devices 1 are arranged in parallel and vertically in the direction of the steel wire 3 entering the pickling tank 3. Among them, the pickling tank 2 is a rectangular pickling tank, and the steel wire 3 is a stainless steel wire.

[0023] The anti-tampering wire device 1 includes a fixed block 1.1 fixedly welded on both sides of the inner wall of the pickling tank 2, that is, the fixed block 1.1 includes a left fixed block and a right fixed block, which are respectively fixedly welded on the left and right sides of the inner wall of the pickling tank 2, and the upper end of the fixed block 1.1 is provided with a through hole 1.2 along the width direction of the fixed block 1.1, and a screw 1.3 passes through the through hole 1.2, and the screw 1.3 is fixedly connected to the fixed block 1.1 through a nut 1.4 and forms an upper limit 4.1; the upper end of the fixed block 1.1 A U-shaped groove 1.5 connected to the through hole 1.2 is also provided, and the bottom end of the U-shaped groove 1.5 is a lower limit 4.2. A solid plastic roller 1.6 is provided above the bottom end of the U-shaped groove 1.5 and is located below the screw 1.3, that is, the solid plastic roller 1.6 can be movably moved up and down between the upper limit 4.1 and the lower limit 4.2, so that the jumping steel wire 3 is buffered, and part of the impact force is removed, and the jumping steel wire 3 is limited below the solid plastic roller 1.6 and cannot jump out of the pickling tank 2. The bottom end of the U-shaped groove 1.5 is higher than the surface of the steel wire 3, that is, the lowest surface of the solid plastic roller 1.6 is higher than the surface of the steel wire 3. With this arrangement, the steel wire 3 that is traveling normally without jumping will not contact the solid plastic roller 1.6, and will not cause friction, which will not affect the surface quality of the steel wire 3 and reduce the wear on the anti-twisting wire device 1.

[0024] Among them, the fixing block 1.1 is a plastic fixing block, the plastic screw is a plastic fiber screw M8×60, and the plastic nut is a plastic limit nut M8.

[0025] In practical applications, first, the two fixing blocks 1.1 are welded to the left and right sides of the inner wall of the pickling tank 2 respectively, ensuring that the lower limit of the fixing block 1.1 is higher than the surface of the steel wire 3, and one end of the solid plastic roller 1.6 is placed above the bottom end of the U-shaped groove 1.5 of one fixing block 1.1, and the other end of the solid plastic roller 1.6 is placed above the bottom end of the U-shaped groove 1.5 of the other fixing block 1.1, and then the screw 1.3 passes through the through hole 1.2 and is fixedly connected to the fixing block 1.1 through the nut 1.4. When the stainless steel wire 3 in the pickling tank 2 moves forward, the solid plastic roller 1.6 presses the jumping steel wire 3 to prevent it from jumping out of the pickling tank 2. When the stainless steel wire 3 needs to be replaced, the screw 1.3 and the nut 1.4 are removed, and the solid plastic roller 1.6 is taken out. After the replacement is completed, the solid plastic roller 1.6, screw 1.3 and nut 1.4 are installed in sequence.

[0026] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
