In the related art, the powder filling rate of the flux-cored welding wire is not the same everywhere. In the production of flux-cored welding wire, in order to ensure that the filling rate of the traditional Chinese medicine powder of the flux-cored welding wire meets the production requirements, it is mainly determined whether the filling rate meets the requirements by stopping sampling during the production process to check the filling rate. A section of the welding wire is peeled off, the powder is taken out, and the weight of the powder and the metal are respectively weighed to calculate the filling rate. This detection method easily leads to increased work, reduced production efficiency, and resulted in a large amount of waste of materials.

Referring to FIG. 1 , the present embodiment provides a controller 16 , an apparatus 1 for detecting the filling rate of a flux-cored wire, and a method for detecting the filling rate of a flux-cored wire, which can effectively improve the above-mentioned technical problems.

Specifically, please refer to FIG. 1 , the flux-cored wire filling rate detection device 1 includes an acting member 12 , a collecting member 13 and a controller 16 , and the acting member 12 is configured to bend the bending portion 21 of the flux-cored welding wire 2 to a preset value. Curvature, the collecting part 13 is configured to output a first signal representing the actual deflection when the bending part 21 is bent to reach the preset curvature, the controller 16 communicates with the collecting part 13, and after the controller 16 receives the first signal, The actual deflection can be compared with the preset deflection range, and according to the comparison result, it can be determined whether the actual filling rate of the bent portion 21 is within the preset range.

In this way, the flux-cored wire filling rate detection device 1 can detect whether the filling rate of the flux-cored welding wire 2 is within a preset range without stripping the flux-cored welding wire 2 , which can effectively improve production efficiency and reduce material waste.

It can be understood that, in this embodiment, since the actual deflections are different when the bending portions 21 with different filling rates are bent to the preset curvature, it is determined by judging that the bending portion 21 is bent to the preset curvature Whether the actual deflection is within the preset deflection range, it can be determined whether the actual filling rate of the bent portion 21 is within the preset range. The above detection principle will be described in detail below.

When the bending portion 21 of the flux-cored welding wire 2 is bent to a preset curvature, the outer contour of the bending portion 21 forms a smooth deflection line. At point B of the section as shown in Figure 2-4, when there is too much or too little powder in the flux-cored welding wire 2, it is most likely to have a sudden change in curvature at point B, resulting in sharp sawtooth cracks or sharp angles, that is, an obvious sudden change in deflection . Specifically, when the content of the powder inside the flux-cored welding wire 2 is too high, that is, when the filling rate is too high, a sawtooth crack will occur on the outside of point B according to FIG. 3 , and the maximum fluctuation range of the actual deflection will exceed the preset deflection range. When the content of the powder inside the flux-cored wire 2 is too small, that is, when the filling rate is too low, a sharp angle will be formed on the inside of point B in combination with Fig. 4. At this time, the maximum fluctuation range of the actual deflection will also exceed the preset deflection range.

In this way, by comparing whether the actual deflection of the bent portion 21 is within the preset deflection range, it can be determined whether the actual filling rate of the bent portion 21 is within the preset range.

It should be noted that, generally, in actual production, the preset range of the filling rate of the bent portion 21 is set to 8% to 15%. The preset deflection range is the range of deflection composition when the filling rate is within the range of 8% to 15%. The curvature of the curve is the rotation rate of the tangent direction angle to the arc length for a point on the curve, which is defined by differentiation, indicating the degree to which the curve deviates from the straight line. A numerical value that mathematically indicates how much a curve bends at a certain point. The greater the curvature, the greater the curvature of the curve. In this embodiment, the preset curvature cannot be too large, otherwise it is easy to cause the flux-cored welding wire 2 to be bent too much and to be broken or damaged. Of course, the preset curvature cannot be too small, so that the deflection of the flux-cored welding wire 2 will not change much, which will result in inaccurate detection of the filling rate. Specifically, the preset curvature may be determined according to parameters such as the material of the actual flux-cored welding wire 2 , the diameter of the flux-cored welding wire 2 , and the bending strength of the flux-cored welding wire 2 .

In addition, the principle that the actual powder content inside the flux-cored wire 2 affects the actual deflection is:

若药芯焊丝2药粉的填充量不合格，取极限的情况为空心的情况，则药芯焊丝2的截面为空心圆形截面，此时，对于圆心点的截面极惯性矩I_p＝πD⁴(1-a⁴)/32，a＝d/D。An important geometric parameter to measure the bending resistance of the flux-cored wire 2 is the polar moment of inertia of the section. The orthogonal coordinate system shown in Figure 2 can be set. The polar moment of inertia of a section at any point is equal to the sum of the quadratic moments of the section in any set of orthogonal coordinate systems with the point as the origin. Take a section of the flux-cored welding wire 2 at point B, referring to FIG. 5 , in this section, the outer diameter of the flux-cored welding wire 2 is D, and the inner diameter (the diameter of the powder) is d. If the flux-cored welding wire 2 is filled with qualified powder, the flux-cored welding wire 2 is solid. At this time, the cross-section of the flux-cored welding wire 2 is a solid circular cross-section.

If the filling amount of the flux-cored welding wire 2 is unqualified, and the limit is taken as the hollow case, the cross-section of the flux- _cored welding wire ² is a hollow circular cross-section. (1-a ⁴ )/32, a=d/D.

Here, it can be inferred that the polar moment of inertia of the cross section of the flux-cored welding wire 2 is different depending on the content of the powder. When the polar moment of inertia of the section is different, the bending section coefficient W (W=I _p /D) is different. Under the same bending force, the maximum deflection on the deflection line is finally different (plastic deformation degree).

Therefore, in this embodiment, it can be determined whether the actual filling rate of the bent portion 21 is within the preset range by whether the actual deflection of the bent portion 21 of the flux-cored welding wire 2 is within the preset deflection range. The filling rate of the bending part 21 that is not easy to detect is converted into the actual deflection of the bending part 21 that is intuitive and easy to detect, which is convenient for detection, effectively improves the production efficiency, and at the same time does not cause waste of the flux-cored welding wire 2 .

It should be noted that, in this embodiment, an image acquisition device is selected for the acquisition part 13, and the image acquisition device is configured to output a first signal representing an actual outer contour image when the bending portion 21 is bent to a preset curvature, and the controller 16 After receiving the first signal, compare the actual outer contour image with the preset outer contour image to determine whether the actual outer contour image is within the range covered by the preset outer contour image. If the actual outer contour image is within the range covered by the preset outer contour image, it means that the actual filling rate of the bending portion 21 is within the preset range, which is a qualified state. Correspondingly, if part or all of the actual outer contour image exceeds the range covered by the preset outer contour image, it means that the actual filling rate of the bent portion 21 is not within the preset range, which is an unqualified state.

In other embodiments, the collecting element 13 can also use a deflection measuring device, which can directly output a first signal representing the actual deflection value when the bending portion 21 is bent to a preset curvature, and the controller 16 receives the first signal Afterwards, by comparing the actual deflection value with the preset deflection range, it can also be determined whether the actual filling rate of the bent portion 21 is within the preset range.

It should be noted that, in this embodiment, a pulley is selected as the acting member 12 . When the flux-cored welding wire 2 goes around the pulley, under the action of the pulley, the bent portion 21 of the flux-cored welding wire 2 can be bent to a preset curvature. In practical applications, pulleys of different specifications can be replaced according to the preset curvature value.

Referring to FIG. 1 , in this embodiment, the flux-cored welding wire 2 can move along the preset track 15 . When the flux-cored welding wire 2 moves along the preset track 15 , the different bending portions 21 of the flux-cored welding wire 2 are continued by the acting member 12 . Bend to preset curvature. In this way, during the movement of the flux-cored welding wire 2 along the preset track 15, the collecting member 13 can collect the actual outer contour images of the different bending parts 21, and can determine whether the filling rate of the different bending parts 21 is within the preset range, so as to The detection operation of the entire flux-cored welding wire 2 can be completed.

Specifically, in this embodiment, the flux-cored welding wire filling rate detection device 1 further includes a winding device 17 , and the winding device 17 acts on the flux-cored welding wire 2 to drive the flux-cored welding wire 2 to move along the preset track 15 . It should be noted that the movement of the flux-cored welding wire 2 along the preset track 15 may be a uniform movement or a variable speed movement. When moving at a constant speed, it is more favorable for the acting member 12 to bend the different bending parts 21 of the flux-cored welding wire 2 .

Referring to FIG. 1 , in this embodiment, the number of the acting members 12 is multiple, the multiple acting members 12 are arranged at intervals, and the flux-cored welding wire 2 is wound around the multiple acting members 12 at the same time. The above-mentioned preset track 15 can be formed between the acting members 12 , and the flux-cored welding wire 2 extends along the preset track 15 and moves along the preset track 15 under the action of the winding device 17 .

In this way, when the flux-cored welding wire 2 moves along the preset track 15 , the same bending part 21 can be bent by different acting members 12 to reach the preset curvature at different times, and can adjust the actual deflection of the same bending part 21 . Perform multiple tests to improve the accuracy of test results.

It should be noted that, in this embodiment, two adjacent acting members 12 are arranged in a staggered manner, and the two adjacent acting members 12 are configured to act on opposite sides of the flux-cored welding wire 2 respectively. The bending directions of the different bending parts 21 bent by the two acting members 12 are opposite, so that the concave sides of the two adjacent bending parts 21 have opposite directions. Such an arrangement makes it easier for the bending portions 21 that are bent to reach the preset curvature at the same time to interfere with each other, and also facilitates the smooth movement of the flux-cored welding wire 2 along the preset track 15 .

Specifically, with reference to FIG. 1 , in this embodiment, the plurality of acting members 12 are distributed along the first preset direction, and the drug core detection device further includes a plurality of adjusting members 14 , the number of which is the same as the number of the acting members 12 The same and one-to-one correspondence, that is to say, one adjusting member 14 is configured to adjust one acting member 12 . Specifically, the adjustment member 14 is drive-connected with the corresponding action member 12, so that the action member 12 can move along the second preset direction, wherein the first preset direction and the second preset direction are set at an included angle k, 0° <k<180°.

Taking FIG. 1 as an example, the first preset direction is the direction indicated by the arrow g and the arrow h in FIG. 1 , the second preset direction is the direction indicated by the arrow s and the arrow t in FIG. The second preset directions are perpendicular to each other.

In the actual production process, according to the different preset curvatures, the distance between the two adjacent acting members 12 in the second preset direction can be changed under the adjustment action of the adjusting member 14, so that the bending portion 21 The preset curvatures achieved by the bending of the acting member 12 are different.

Specifically, in this embodiment, the adjusting member 14 is made of a screw, the axial direction of the adjusting member 14 is the same as the second preset direction, the adjusting member 14 and the acting member 12 are threadedly matched, and when the adjusting member 14 rotates around its own axis, The acting member 12 can be driven to move along the axial direction of the adjusting member 14 .

Please refer to FIG. 1 , in this embodiment, the flux-cored wire filling rate detection device further includes a handle 18 , and one end of each adjusting member 14 is connected with a handle 18 , and the handle 18 is convenient for the staff to hold, and the staff rotates the handle 18 When the adjusting member 14 is driven to rotate around its own axis, the acting member 12 can move along the axial direction of the adjusting member 14 .

In addition, in this embodiment, each adjustment member 14 is movable along the first preset direction, so that the adjustment member 14 can also drive the action member 12 along the first preset direction during the movement of the adjustment member 14 along the first preset direction. By moving, the distance between the two adjacent acting members 12 in the first preset direction can be changed, so that the preset curvatures of the bending portion 21 obtained by bending the acting members 12 are different.

It can be understood that, in the actual production process, the specific preset curvature value that the bending portion 21 needs to be bent to reach is determined according to the material, diameter and other factors of the flux-cored welding wire 2 . The adjustment action of the device determines the installation positions of the plurality of action pieces 12 to form the preset track 15 . Then, the flux-cored welding wire 2 is extended along the preset track 15 , and the winding device 17 is activated to drive the flux-cored welding wire 2 to move along the preset track 15 .

It should be noted that, in this embodiment, during the movement of the flux-cored welding wire 2 along the preset track 15 , the acting member 12 can rotate relative to the adjusting member 14 around its own axis, which can reduce the distance between the flux-cored welding wire 2 and the flux-cored welding wire 2 . Friction, reducing the damage of the flux-cored wire 2.

It should be noted that, the communication mode between the acquisition module 161 and the acquisition component 13 may be wired communication or wireless communication.

In this embodiment, the actual deflection of the bending portion 21 is represented by the outer contour image of the bending portion 21 , and the collecting component 13 outputs the first image representing the actual outer contour image when the bending portion 21 is bent to reach the preset curvature. A signal, after the acquisition module 161 acquires the first signal, the comparison module 162 compares the actual outer contour image with the range covered by the preset outer contour to determine whether the actual outer contour image is within the range covered by the preset outer contour.

In other embodiments, the actual deflection of the bending portion 21 can be represented by an actual value, and the collecting component 13 outputs a first signal representing the actual deflection value when the bending portion 21 is bent to reach a preset curvature, and the acquisition module After 161 acquires the first signal, the comparison module 162 compares the actual deflection value with the preset deflection range to determine whether the actual deflection value is within the preset deflection range.

It should be noted that, in this embodiment, the controller 16 further includes a sending module 164, and the sending module 164 is configured to send a second signal indicating that the actual filling rate is not within the preset range, the flux-cored wire filling rate detection The device 1 further includes an actuator 19, and the actuator 19 is configured to receive the above-mentioned second signal and perform a reminding action.

The actuator 19 may be an alarm, and after receiving the second signal, the alarm will sound an alarm to remind the relevant staff.

The actuator 19 may also be a display screen. After receiving the second signal, the display screen displays information that the filling rate of the bending portion 21 is unqualified at this time, so as to remind the relevant staff.

In this embodiment, the above-mentioned rewinding device 17 can also receive the second signal. After receiving the second signal, the rewinding device 17 will stop working, which is convenient for the staff to find the bent portion 21 with an unqualified filling rate.

It should be noted that the communication mode between the sending module 164 and the actuator 19 may be wired communication or wireless communication. Similarly, the communication mode between the sending module 164 and the winding device 17 may be wired communication, or Can be wireless communication.

In this way, the method for detecting the filling rate of the flux-cored welding wire can detect whether the filling rate of the flux-cored welding wire 2 is within the preset range without stripping the welding wire, which can effectively improve the production efficiency and reduce the waste of materials.

It should be noted that, the method for detecting the filling rate of the flux-cored welding wire can be completed by the controller 16 mentioned above, and can also be used by a specific inspector. Wherein, when comparing the actual deflection with the preset deflection range, the inspecting personnel can judge whether the actual filling rate of the bending portion 21 is within the preset range through experience.
