Description

Technical Field

[0001] The invention relates to the technical field of metal fiber manufacturing, and in particular to a preparation device and a preparation method for iron-nickel alloy fibers. Background Art

[0002] Ni-Fe is a nickel-iron magnetic alloy with about 80% nickel and 20% iron. It has a very high magnetic permeability, which makes it useful as a core material for electrical and electronic devices, and also for magnetic shielding to block magnetic fields. In addition to high permeability, its other magnetic properties are low coercivity, near-zero magnetostriction, and significant anisotropic magnetoresistance. Low magnetostriction is critical for industrial applications, allowing it to be used in thin films where otherwise variable stresses would cause devastatingly large changes in magnetic properties.

[0003] As a new type of material, iron-nickel alloy fiber has both the inherent advantages of iron-nickel alloy itself and the characteristics of fiber materials, and is widely used in high-tech fields such as electromagnetic shielding and telecommunications electronics. Due to the difficulty in processing iron-nickel alloy fibers, the minimum diameter of iron-nickel alloy fibers currently produced on the market is 40μm, which limits their application in some high-end fields. At the same time, the transportation during the processing of material products is usually completed by a wire drawing machine, which needs to be collected and fixed, then disassembled and put into the next processing pool for processing, and then collected and fixed, which has low efficiency. Based on this, the present invention provides a preparation method and preparation equipment for iron-nickel alloy fibers. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention aims to provide a method for preparing small-diameter iron-nickel alloy fibers and a preparation device for assisting product transfer.

[0005] The technical solution adopted by the present invention is: a method for preparing an iron-nickel alloy fiber, comprising the following steps:

[0006] S1. The iron-nickel alloy wire is successively subjected to pickling activation treatment, pre-nickel plating treatment, and surface copper plating treatment to obtain a copper-plated iron-nickel alloy wire and then dried;

[0007] S2. 500 to 3000 copper-plated iron-nickel alloy wires obtained in step S1 are loaded into the inner cavity of a copper tube with equal length for coating to obtain a prefabricated alloy wire;

[0008] S3. Using a drawing die to stretch the prefabricated alloy wire in S2 to obtain a composite wire;

[0009] S4: the composite wire obtained in S3 is repeatedly drawn continuously, and annealed when the deformation reaches 50% to 60%. The composite wire is annealed at a temperature of 700° C. to 800° C. for 20 min to 50 min. The drawing and annealing are repeated multiple times to obtain a rough finished wire having a target finished product diameter.

[0010] S5: removing the copper tube layer and the electroplated copper layer on the surface of the crude finished product wire obtained in S4 to obtain an iron-nickel alloy fiber.

[0011] In one embodiment, the iron-nickel alloy wire has a diameter of 0.1-0.3 mm.

[0012] In one embodiment, the pickling activation treatment is implemented as an immersion pickling solution post-treatment: the pickling solution is a sulfuric acid solution with a unit volume of 150g / L to 300g / L; the pickling temperature is 20 to 35°C, the power-on voltage is 3 to 5V, and the pickling time is 40 to 60S.

[0013] In one embodiment, the pre-nickel plating treatment is implemented as a post-treatment of immersing in a nickel plating solution; the nickel plating solution comprises: 40-80 g / L nickel chloride, 0.1-0.5 mol / L hydrochloric acid; the current density is 4-8 A / dm 3 The pre-plating temperature is 30-40° C., and the pre-plating time is 2-3 minutes. After the implementation, a nickel layer is obtained on the surface of the iron-nickel alloy.

[0014] In one embodiment, the nickel plating layer has a thickness of 1 to 5 μm.

[0015] In one embodiment, the surface copper plating treatment includes immersion in a main plating solution post-treatment, the main plating solution includes: 1mol / L~2mol / L sulfuric acid solution, 100~200g / L copper sulfate solution; the current density is 20~40A / dm3, the temperature is 30~40℃, and the main plating time is 30~40min.

[0016] In one embodiment, the copper-to-steel ratio of the copper-plated iron-nickel alloy wire is 25% to 35%.

[0017] In one embodiment, the deformation amount of a single pass in drawing is 3-6%, and the moving speed between wire bodies is 4-8 m / min.

[0018] In one embodiment, the method for removing the copper tube layer in step S5 is: immersing in nitric acid with a unit capacity of 150-300 g / L; the method for removing the electroplated copper layer in step S5 is: immersing in ammonium sulfate with a unit capacity of 100-200 g / L, 50-100 g / L copper sulfate and 3 mol / L ammonia solution.

[0019] In one embodiment, a device for preparing iron-nickel alloy fiber is also included, comprising:

[0020] A box body, which is multiple and arranged in parallel, is provided with a material transfer member on the box body, and the material transfer member includes a fixed rotating rod, the fixed rotating rod is arranged in the inner cavity of the box body, two groups of top rotating rods are arranged above the fixed rotating rod, and a driving motor is arranged on the top rotating rod, and a conveyor belt is arranged between the fixed rotating rod and the top rotating rod, and a material collecting plate is arranged at the bottom end of the box body, and the material collecting plate includes a ramp plate and a connected arc-shaped edging plate, and the material collecting plate closes the bottom of the box body, and a swing motor is arranged on the side of the material transfer member close to the connected box body, and a material-pickling rod is arranged on the swing motor;

[0021] There are multiple lifting members, the lifting devices are evenly arranged on a group of the conveyor belts, the lifting members and the material transfer members are staggered, the lifting members include right-angle rods, an inclined plate is arranged at one end of the right-angle rods close to the conveyor belt, a first spring is arranged between the inclined plate and the conveyor belt, a material guard plate is arranged at one end of the right-angle rods away from the conveyor belt, and a second spring is arranged between the material guard plate and the right-angle rods;

[0022] The number of the leaking parts is the same as that of the lifting parts. The leaking parts are arranged on another conveyor belt close to the lifting machine. The leaking parts include a lifting plate, and a plurality of leaking holes are arranged on the lifting plate.

[0023] The beneficial effects of the present invention are as follows: the present invention is a preparation device for iron-nickel alloy fiber, and the specific implementation method is as follows:

[0024] First, after pouring the liquid required to treat the iron-nickel alloy wire into different boxes in turn, the iron-nickel alloy wire is put into the liquid to be treated first, and then the slope plate and the arc-shaped edging plate are used to gather and sink it to the bottom of the liquid pool. After the soaking, heating, ionization and other processes in the above operations are implemented, the driving motor is started to drive the conveyor belt on the top rotating rod to rotate periodically. Since the material transmission parts and the lifting parts are staggered, during the movement of the conveyor belt, the cooperation of the right-angle rod and the lifting plate tilts and lifts the iron-nickel alloy wire, and the lifting height of the material transmission parts is kept higher than the lifting plate, so that the iron-nickel alloy wire can be first overlapped with the right-angle rod and then separated from the soaking liquid. Due to the effect of the tilt, the excess soaking flows out from the leakage hole on the lifting plate, and at the same time, the auxiliary strong exhaust fan accelerates the drying. This is the existing technology for existing liquid cleaning, so it will not be repeated. Since the iron-nickel alloy wire is first overlapped with the lifting plate, one side is higher than the right-angle rod, and then it is flipped by gravity. The inclined plate and the material protection plate are separated from the right-angle rod and fall and overlapped again to avoid the inability to effectively clear the residual liquid when it is separated from the liquid;

[0025] At this time, it can be determined whether to put the iron-nickel alloy wire into the liquid-containing box of the next process. If not, the iron-nickel alloy wire continues to fall into the box under the action of the conveyor belt. If necessary, start the swing motor, and after the conveyor belt lifts one side of the iron-nickel alloy wire, the swing motor swings the material removal rod to fall under the iron-nickel alloy wire. When the conveyor belt drops the iron-nickel alloy wire, the swing motor drives the material removal rod to return to its position, so that the iron-nickel alloy wire falls into the adjacent box with one side tilted, thereby completing the transportation of the iron-nickel alloy wire without the need for a wire drawing machine to fix it.

[0026] Through the cooperation of the above method and preparation equipment, the fiber size of the iron-nickel alloy wire is effectively reduced to 12μm. At the same time, the problem of low efficiency caused by multiple transfers of different boxes during the pretreatment of the iron-nickel alloy wire before fiber production is simplified. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
