Description

Technical Field

[0001] The utility model relates to the technical field of amorphous product processing, and in particular to a coated amorphous strip, an amorphous alloy profile, an alloy product structure and a processing system. Background Art

[0002] At present, amorphous alloy materials are widely used in light and heavy industries. Amorphous alloy materials can usually be selected in the form of a winding strip structure to meet storage applications, while preparing materials for the next step of cutting and processing into different profile structures.

[0003] In the prior art, in order to meet the specific structural setting of amorphous alloy materials, it is necessary to perform shape processing on the amorphous alloy materials to obtain profiles with specific structural shapes for application; however, due to the brittle characteristics after heat treatment, the prior art generally requires the amorphous alloy materials to be cut into shapes before performing the heat treatment process; amorphous alloy materials that have not been heat treated have the characteristic of strong material toughness, so under the premise of not being heat treated, the profiles obtained by punching and cutting will have different degrees of curling and burrs, and secondary processing is required, otherwise the stacking coefficient of the product made from the profile will be reduced by 20-35%, and the saturation magnetic induction intensity Bs value of the product will be reduced.

[0004] After the amorphous alloy is heat treated to remove internal stress, the disordered atomic structure (no grain boundaries) causes the amorphous alloy to deform in a local shearing manner, making the amorphous alloy exhibit irregular intermittent rheological behavior during deformation. It manifests as brittle fracture, which is the essence of the glassy state of amorphous alloys; if the shearing operation is directly performed to process alloy material profiles of specific shapes and specifications, the continuous alloy material surface will be broken during the shearing process. This is the bottleneck that limits the large-scale engineering application of amorphous alloys. How to improve the plastic deformation capacity of amorphous alloys and meet the requirements of more free cutting and processing of amorphous alloy materials after heat treatment is a technical problem in the industry.

[0005] For the processing of special-shaped amorphous alloy profiles, if heat treatment is performed before cutting and forming, the shape of the amorphous alloy material will be regular, and the material's internal stress will be removed more fully when heated evenly in the treatment furnace. The magnetic properties of the heat-treated material will be consistent, and the performance will be stable and will not fluctuate. If heat treatment is performed after cutting and forming, the shape of the amorphous alloy will be irregular after cutting and forming, and there will be uneven heating and insufficient removal of the material's internal stress during the heat treatment process. As amorphous alloy materials are very sensitive to heat and stress, the magnetic properties of the heat-treated material will not be consistent, and the performance will fluctuate evenly. Utility Model Content

[0006] The purpose of the utility model is to provide a coated amorphous strip, an amorphous alloy profile, an alloy product structure and a processing system in order to overcome the deficiencies of the prior art.

[0007] The coated amorphous strip is in the shape of a long strip as a whole and comprises an amorphous alloy layer applied after heat treatment. An adhesive film is arranged on at least one side of the amorphous alloy layer, and the adhesive film forms film stress on the surface of the amorphous alloy material in the amorphous alloy layer.

[0008] The structure setting principle is as follows:

[0009] The coated amorphous strip is made by setting an adhesive film on the surface of the amorphous alloy strip after heat treatment. The adhesive film will form film stress (adhesion and / or tension) on the surface of the amorphous alloy strip. Under the action of the film stress, the coated amorphous strip can remain continuous during shearing and will not cause brittle fracture and breakage.

[0010] In the composite application of the amorphous alloy strip as a bonding film, an amorphous alloy profile can be obtained by cutting the strip; the amorphous alloy profile is in a circular, triangular, square, polygonal, or irregular shape, and has a cutting edge on the periphery, and the cutting edge is smooth and flat.

[0011] Of course, the amorphous alloy profile is not limited to the one obtained by cutting in the coated amorphous strip; based on the characteristics of the coating, the obtained amorphous alloy profile can also be further cut and processed for a second time.

[0012] Preferably, in the application of the coated amorphous strip and amorphous alloy profile, the material of the amorphous alloy layer can be selected to be one or more of an iron-based amorphous alloy, an iron-nickel-based amorphous alloy, a cobalt-based amorphous alloy, an iron-based nanocrystalline alloy, and an ultra-microcrystalline alloy. Without exceeding the principle of this solution, this solution is also applicable to the conventional soft magnetic alloy profile in the art.

[0013] Furthermore, the adhesive film includes a first adhesive film, which can be applied based on the protective film layer structure with adhesive in the prior art; specifically, the adhesive film includes an adhesive layer, and an upper film is arranged on the upper side of the adhesive layer; through the adhesive layer, the adhesive film is adhered to the surface of the amorphous alloy layer as a whole; wherein, the adhesive film is arranged to be one of a silicone PET protective film, an acrylic PET protective film, a PET-based tape or a tape without a base material, a BOPP tape, a cloth-based tape, a kraft paper tape, a masking tape, a fiber tape, a PVC tape, and a PE foam tape.

[0014] Furthermore, the adhesive film includes a second adhesive film, the second adhesive film includes a coating film coated on one side of the amorphous alloy layer, and the coating film is set to be one of acrylic glue, epoxy resin glue, silicone, AC glue coating, and acrylic resin. The adhesive film is processed and applied on the amorphous alloy strip by spraying or scraping in the existing technology.

[0015] Furthermore, both side surfaces of the amorphous alloy layer are processed by applying the first adhesive film and / or the second adhesive film.

[0016] Furthermore, the amorphous alloy profiles are stacked and / or spliced ​​to obtain amorphous alloy products. Based on the application of stacking, splicing and other technical applications, the amorphous alloy profiles of the utility model can be used for processing and application of amorphous alloy motor stator and rotor core products, or processed to form corresponding amorphous alloy electromagnetic shielding sheet products and inductor core products in the prior art.

[0017] A processing system for processing and preparing the coated amorphous strip as described above; it includes a heat treatment system, a splicing processing equipment is arranged at the discharge end of the heat treatment system, the splicing processing equipment includes a frame, a strip unwinding roller for unwinding the wound amorphous alloy strip is arranged on the frame; a coating device for performing a bonding film coating treatment on the unwound amorphous alloy strip is arranged on one side of the strip unwinding roller.

[0018] Preferably, in order to carry out the processing and application of the first adhesive film, the coating device includes a film feed roller for attaching the wound adhesive film and a waste roller for guiding waste from the wound film feed roller, which are arranged on the frame; a pressing roller group is arranged on one side of the discharge end of the strip feed roller and the film feed roller. Specifically, the roller group in the pressing roller group adopts a silicone roller structure, the material hardness of the silicone roller is 70-95HB; the diameter of the silicone roller is 50-80mm.

[0019] Furthermore, two groups of film unloading rollers are provided, one group of film unloading rollers is provided on one side of the discharge end of the strip unloading roller, and the other group of film unloading rollers is provided on the other side of the discharge end of the strip unloading roller.

[0020] In view of an application of bonding and laminating an amorphous alloy strip with an adhesive film with an adhesive layer, the processing system is arranged in the form of roller processing to engage and cooperate the wound adhesive film and the amorphous alloy strip, so that the adhesive film is bonded to one side of the amorphous alloy strip; then, a pressing roller group is used for pressing to squeeze out the air between the bonded adhesive film and the amorphous alloy strip, so that the adhesive film and the amorphous alloy strip are more tightly bonded, thereby obtaining the coated amorphous strip.

[0021] A finishing section is provided at the discharge end of the lamination roller group; the finishing section comprises a finishing winding roller for winding and storing the formed coated amorphous strip, so as to wind up the produced coated amorphous strip and then sell it as an independent product.

[0022] The finishing section also includes a cutting device for cutting the coated amorphous strip. The cutting device is a stamping cutting device. By coating both side surfaces of the amorphous alloy strip with an adhesive film and cooperating with the stamping cutting process of the prior art, during the punching process, the upper blade of the punching applies shear stress to the upper surface of the amorphous alloy strip coated on the upper side, and the lower blade applies shear stress to the lower surface of the amorphous alloy strip coated on the lower side, so that the strip will break in the direction of the shear stress when punched by the die, and will not produce glass-like irregular brittle and arbitrary fractures, thereby realizing the profile shape processing and cutting application of the heat-treated amorphous alloy strip.

[0023] The finishing section includes a coating device for performing secondary coating treatment on the coated amorphous strip. For example, in order to be used for processing the second adhesive film, the coating device is configured as a coater or a sprayer.

[0026] 2. Based on the application of the structural combination setting of the processing system, the adhesive film can be effectively attached to the surface of the amorphous alloy strip after the heat treatment of the winding. The application of the pressing roller group can effectively press and adhere the introduced adhesive film and the amorphous alloy strip, avoiding crushing the amorphous alloy strip and ensuring that the adhesive film is tightly adhered to the amorphous alloy strip.

[0038] The amorphous alloy profiles are stacked and / or spliced ​​to obtain an amorphous alloy product.

[0039] Embodiment 1:

[0040] As a preferred embodiment, the utility model provides a processing system for executing the processing steps of the above-mentioned coated amorphous strip, amorphous alloy profile and amorphous alloy product.

[0041] like Figure 2As shown, the processing system includes a heat treatment system (heat treatment furnace) for heat treatment of the wound amorphous alloy strip. It also includes a splicing processing equipment, which includes a frame, on which are arranged a strip unwinding roller 1 for attaching the amorphous alloy strip wound after heat treatment, a film unwinding roller 2 for attaching the first adhesive film 11 for winding, and a waste roller 3 for guiding waste out of the wound film unwinding roller 2; a pressing roller group 4 is arranged on one side of the discharge end of the strip unwinding roller 1 and the film unwinding roller 2, and a finishing part for subsequent processing of the coated amorphous strip is arranged at the discharge end of the pressing roller group 4.

[0042] In this embodiment, the arranging part is applied as an arranging winding roller 5 for winding and storing the coated amorphous strip.

[0043] The specific structural layout of the processing system is as follows: the strip unloading roller 1 is arranged on one side of the frame, the film unloading roller 2 is arranged on the side of the strip unloading roller 1 facing the other side of the frame, and the film unloading roller 2 is located on the upper side of the strip unloading roller 1; the waste roller 3 is arranged on the side of the film unloading roller 2, and the waste roller 3 is located on the upper side of the film unloading roller 2 and arranged toward one side of the frame; a guide wheel 21 is arranged between the film unloading roller 2 and the strip unloading roller 1.

[0044] The first adhesive film 11 includes an adhesive layer 111 and an upper film 112 located on the upper side of the adhesive layer 111, and a lower film located on the lower side of the adhesive layer 111; the sub-guide wheel 21 is used to guide and separate the torn lower film; a splicing channel is formed between the film unloading roller 2, the sub-guide wheel and the strip unloading roller 1 to guide the first adhesive film 11 with the upper film 112 and the adhesive layer 111 to be initially bonded and spliced ​​with the amorphous alloy strip; a waste channel is formed between the strip unloading roller 1, the sub-guide wheel 21 and the waste roller 3 to uniformly recycle and sort the torn lower film (waste).

[0045] The pressing roller group 4 is arranged at the lower side of the strip material discharge roller 1 and toward the other side of the frame. The pressing roller group 4 includes an upper pressing roller and a lower pressing roller.

A pressing channel is formed between the strip material discharge roller 1 and each group of pressing roller groups 4. Each group of pressing roller groups 4 presses and splices the input amorphous alloy strip and the first adhesive film 11 for preliminary bonding and splicing in turn, so that the first adhesive film 11 and the amorphous alloy strip are more stably bonded, and the excess air between the film and the amorphous alloy strip is discharged. From one side of the frame to the other side, the pressing forces applied by each group of pressing roller groups 4 to the input material are set to increase in sequence; after being pressed by the pressing roller groups 4, the amorphous alloy strip and the first adhesive film 11 are combined to form the coated amorphous strip.

[0050] Embodiment 2:

[0051] In this embodiment, another configuration and application scheme of the processing system of the utility model is illustrated.

[0052] The difference between this embodiment and the above-mentioned embodiment 1 lies in the specific application of the finishing part. In this embodiment, the finishing part includes a cutting device 6 for cutting the coated amorphous strip, and the cutting device 6 is a punching cutting device.

[0053] The material is led out from the discharge end of the lamination roller group 4, and the led out bonded and spliced ​​coated amorphous strip is input into the cutting device 6.

[0054] Embodiment 3:

[0055] In this embodiment, another configuration and application scheme of the processing system of the utility model is illustrated.

[0056] like Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiment 1 lies in the specific application difference of the finishing part. In this embodiment, the finishing part includes a coating device 7 for performing secondary coating treatment on the coated amorphous strip.

[0057] The coating device 7 is applied as a coating machine or a spraying machine; through the existing spraying technology, acrylic glue, epoxy resin glue, silicone, AC glue coating, acrylic resin and other adhesive coatings are sprayed and coated on the other side of the amorphous alloy strip that is not coated with the adhesive film, and the second adhesive film 12 is coated on the other side of the amorphous alloy strip for application. The coated amorphous strip with films on both sides is obtained in a single processing flow.

[0058] Subsequently, the coated amorphous strip with films on both sides can be input into the corresponding cutting device 6 for cutting to obtain an amorphous alloy profile. The corresponding amorphous alloy product structure can be obtained through manual stacking or automatic splicing.

[0059] In the prior art, if the amorphous alloy material (amorphous alloy strip) after heat treatment is directly cut, the obtained amorphous alloy profile will have curling and burrs, which does not meet the characteristics of a qualified product.

[0060] Based on the forming process of the amorphous alloy material of the utility model, a coated amorphous strip is first prepared, and then punched and cut to simply obtain an amorphous alloy profile with smooth and flat cutting edges in any shape.

[0061] The above is only a preferred implementation of the present invention. Those skilled in the art can still modify the embodiments without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as within the protection scope of the present invention.
