Description
Technical Field
The invention relates to the field of amorphous alloy materials, in particular to an amorphous alloy iron core shearing forming auxiliary device and an amorphous alloy iron core auxiliary forming method.
Background
The amorphous alloy material is a high and new technology soft magnetic material, and is generally obtained by rapidly condensing liquid metal into a thin strip, stripping, grabbing and coiling the thin strip, and finally obtaining the amorphous strip. Because the liquid metal is not crystallized and the unordered arrangement of liquid atoms is kept in a greenhouse or at a low temperature, the atoms are not in long-range order, periodicity and regular arrangement any more, but are in a long-range unordered arrangement state. It is this "disordered atomic arrangement" structure that makes the amorphous alloy free from grain boundaries, subgrain boundaries, and second phase particles that hinder the movement of magnetic domain walls, so that the amorphous alloy is easily magnetized with little loss of magnetization, which results in very excellent soft magnetic properties.
Due to the technical process and other reasons, the amorphous strip produced in the prior art has some concave-convex and long marks on the surface, the strip is easy to break and generate scraps when being pressed in the winding process, the thickness of the strip is uneven and the like. These factors affect the performance of amorphous alloy cores, and in actual amorphous core production, the thickness of amorphous strip is often uneven, and the cross section of the strip is thicker and thinner, which affects the performance of the manufactured product (such as an iron core transformer).

the thickness measuring structure vertically corresponds to the conveying surface of the conveying table, and comprises a first thickness measurer for measuring the width of the amorphous alloy strip on one side in the width direction and a second thickness measurer for measuring the width of the amorphous alloy strip on the other side in the width direction;
the rotating mechanism is connected with the conveying table in a transmission way and can drive the conveying table to rotate 180 degrees in the horizontal direction so that the two wide sides of the amorphous alloy strip carried on the conveying table are in a switching state;

When the device in the embodiment is used, the amorphous alloy strip is conveyed onto the conveying table, and the conveying table is controlled to stop conveying when the amorphous alloy strip is conveyed to the trigger position sensor. Then, the thickness of the two sides of the amorphous alloy strip is measured respectively by the thickness measuring structures on the two sides, and if the difference (marked d) between the thickness of one side of the amorphous alloy strip in the width direction and the thickness of the other side of the amorphous alloy strip in the width direction on the conveying table is measured to be smaller than a set thickness deviation limit value (marked dmax), the conveying table conveys the amorphous alloy strip backwards to the next procedure; if d is greater than dmax, the rotating mechanism is started to drive the conveying table to horizontally rotate for 180 degrees so that the two wide sides of the amorphous alloy strip carried on the conveying table are in a state of being reversed, and then the first driver reversely operates so that the amorphous alloy strip still transfers the amorphous alloy strip to the next working procedure backwards. Thus, the amorphous alloy ribbon with d less than dmax is conveyed back in its original state, while the amorphous alloy ribbon with d greater than dmax is conveyed back in a wide direction to a reverse direction.

Examples
Fig. 1 is a schematic structural view of an amorphous alloy core shear molding auxiliary device 100 according to an embodiment of the present invention. Fig. 2 is another view from the perspective of fig. 1. Referring to fig. 1 and 2, an embodiment of the present invention provides an amorphous alloy core shear molding auxiliary device 100, which includes a rotation mechanism B1, a transfer table 9, a thickness measuring structure 5, and a position sensor 3. The transfer table 9 is driven by a first driver 12, and the transfer table 9 is capable of controlled conveyance of the object placed thereon in the forward or reverse direction. The position sensor 3 is electrically connected with the first driver 12, and can be excited and control the first driver 12 to stop driving the conveying action of the conveying table 9 when the amorphous alloy strip conveyed by the conveying table 9 is sensed to be in place. The thickness measuring structure 5 vertically corresponds to the conveying surface of the conveying table 9, and the thickness measuring structure 5 includes a first thickness measurer 17 for measuring the width of the amorphous alloy strip in one widthwise direction and a second thickness measurer 18 for measuring the width of the amorphous alloy strip in the other widthwise direction. The rotating mechanism B1 is configured to be in transmission connection with the conveying table 9 and can drive the conveying table 9 to rotate 180 degrees in the horizontal direction so that the two wide sides of the amorphous alloy strip carried on the conveying table 9 are in a switching state. Further, when the difference between the thickness value of the corresponding side measured by the first thickness measuring device 17 and the thickness value of the corresponding side measured by the second thickness measuring device 18 is smaller than the set thickness deviation limit value, an operation of rotating 180 degrees is performed.
When the device in this embodiment is used, the amorphous alloy strip is transferred onto the transfer table 9, and the transfer table 9 is controlled to suspend the transfer when the amorphous alloy strip is transferred to the trigger position sensor 3. Then, the thickness of the amorphous alloy strip in the width direction is measured by the thickness measuring structures 5 on both sides, and if the difference (denoted as d) between the thickness of one side of the amorphous alloy strip in the width direction and the thickness of the other side of the amorphous alloy strip in the width direction on the conveying table 9 is measured to be smaller than the set thickness deviation limit value (denoted as dmax), the conveying table 9 conveys the amorphous alloy strip to the next process. If d is greater than dmax, the rotating mechanism B1 is started to drive the conveying table 9 to horizontally rotate for 180 degrees so that the two wide sides of the amorphous alloy strip carried on the conveying table 9 are in a state of being reversed, and then the first driver 12 is reversely operated so that the amorphous alloy strip still backwards transfers the amorphous alloy strip to the next working procedure. Thus, the amorphous alloy ribbon with d less than dmax is conveyed back in its original state, while the amorphous alloy ribbon with d greater than dmax is conveyed back in a wide direction to a reverse direction. In this way, the thickness deviations of the two sides of the amorphous alloy strip passing through the two states at least partially cancel each other out when superimposed, so that the total thickness deviation of the two sides of the core formed by superimposing a plurality of the amorphous alloy strips is sufficiently small.
For convenience of installation and operation, the amorphous alloy core shear molding auxiliary device 100 of the present embodiment further includes a base 13. The rotation mechanism B1 includes a second driver 11 fixedly attached to the base 13. The transfer table 9 is connected to the output end of the second driver 11 through a vertically arranged rotating shaft 10, and can rotate under the driving of the second driver 11. The conveyor table 9 comprises a support frame 6 connected to a base 13 and a conveyor belt structure 8 arranged on the support frame 6. The conveyor belt structure 8 is transported in a horizontal direction.
In one implementation of the present embodiment, the mounting bracket 14 is also included. The mounting frame 14 includes a stand 15 and a cross frame 16 connected to the top of the stand 15 and extending in a horizontal direction to correspond to above the transfer table 9. The lower end surface of the cross frame 16 is a mounting surface, and the thickness measuring structure 5 and the position sensor 3 are respectively arranged on the mounting surface of the downward corresponding conveying table 9 of the mounting frame 14. Alternatively, the first thickness measurer 17 includes a plurality of rows of gauges distributed along the length of the amorphous alloy strip, and the lateral width of the amorphous alloy strip is represented as an average value of the thicknesses measured by the plurality of gauges of the row. The second gauge 18 comprises a plurality of rows of gauges distributed along the length of the amorphous alloy strip, the lateral width of the amorphous alloy strip being represented by the average of the thicknesses measured by the rows of gauges. For example, the first thickness measurer 17 and the second thickness measurer 18 are illustrated as including 4 gauges, respectively. The measurer may be, for example, a thickness sensor.
In one implementation of the present embodiment, the position sensors 3 are two in total and are spaced apart along the length of the amorphous alloy strip by a distance equal to the length of the amorphous alloy strip. One of which is activated when the entry of the amorphous alloy strip is detected and the other of which is activated when the in-place amorphous alloy strip is detected. When the two position sensors 3 are respectively excited, the control conveying table 9 stops, so that the amorphous alloy strip stops at a determined position. The position sensor 3 may be a laser sensor.
In one implementation of the present embodiment, a display 2 is further provided on the mounting frame 14, and the display 2 is electrically connected to the thickness measuring structure 5 and is used for displaying the measurement result of the thickness measuring structure 5. The display 2 may be, for example, a liquid crystal display. By displaying the thickness value, personnel can know the thickness change of the amorphous alloy strip conveniently, and manual intervention interference adjustment is facilitated when large abnormality occurs for example.
In this embodiment, a controller 1 is also provided, and the controller 1 may be provided on the mounting frame 14, and may be provided integrally with the display 2. Wherein the controller 1 is electrically connected to the position sensor 3 and the first driver 12 and is configured to control the first driver 12 to stop upon receiving an excitation signal of the position sensor 3. The controller 1 is electrically connected to the first thickness measurer 17, the second thickness measurer 18 and the second driver 11, and is configured to control the second driver 11 to be started to drive the conveying table 9 to rotate 180 degrees when a difference between a thickness value of a corresponding side of the amorphous alloy strip measured by the first thickness measurer 17 and a thickness value of a corresponding side of the amorphous alloy strip measured by the second thickness measurer 18 is smaller than a set thickness deviation limit value.
Referring to fig. 1 and 2, the embodiment of the invention further provides an auxiliary forming method of the amorphous alloy iron core, which is based on the auxiliary device 100 for shearing and forming the amorphous alloy iron core. The auxiliary forming method of the amorphous alloy iron core comprises the following steps:
causing the amorphous alloy strip to be transferred onto the transfer table 9, the transfer table 9 being controlled to suspend the transfer when the amorphous alloy strip is transferred to the trigger position sensor 3;
the thickness of the amorphous alloy strip is measured by the thickness measuring structures 5 on both sides in the width direction, and if the difference (denoted as d) between the thickness of one side of the amorphous alloy strip in the width direction and the thickness of the other side of the amorphous alloy strip in the width direction on the conveying table 9 is measured to be smaller than the set thickness deviation limit value (denoted as dmax), the conveying table 9 conveys the amorphous alloy strip to the next process. If d is greater than dmax, the rotating mechanism B1 is started to drive the conveying table 9 to horizontally rotate for 180 degrees so that the two wide sides of the amorphous alloy strip carried on the conveying table 9 are in a state of being reversed, and then the first driver 12 is reversely operated so that the amorphous alloy strip still backwards transfers the amorphous alloy strip to the next working procedure. Thus, the amorphous alloy strip with d less than dmax is conveyed back in the original state, while the amorphous alloy strip with d greater than dmax is conveyed back in the wide direction in the opposite direction;
by the method, the thickness deviations of the two sides of the amorphous alloy strips in two states can be at least partially counteracted, so that the total thickness deviation of the two sides of the iron core formed by overlapping a plurality of amorphous alloy strips is small enough.
