Technical Field
[0001] The utility model relates to the technical field of natural slope angle detection equipment, in particular to a natural slope angle detection device for metal powder. Background Art
[0002] The natural slope angle is one of the commonly used indicators for evaluating powder fluidity. It refers to the maximum angle that the surface of a pile of powder may produce with a plane. The traditional natural slope angle measurement is carried out by a protractor. In actual measurement work, a special protractor with high precision is also required, so the applicability of the protractor is not wide. When the metal powder detection device in the prior art is used, the natural slope angle of the metal powder is estimated by visual inspection. The visual inspection method is prone to large errors, thereby affecting the accuracy of the natural slope angle finally calculated. Utility Model Content

[0017] Example: Please refer to Figure 1-3A detection device for the natural slope angle of metal powder comprises a base 1, a column 2, a beam support 3 and a funnel 4. The column 2 is vertically installed on the base 1, and the beam support 3 is slidably connected with the column 2. Specifically, the beam support 3 is connected with the column 2 through an adjusting knob 9. Rotating the adjusting knob 9 can adjust the tightness of the beam support 3 and the column 2, thereby facilitating the adjustment of the height of the beam support 3 to meet the detection requirements of the natural slope angles at different heights; a fixing ring 7 is installed on the beam support 3, and the fixing ring 7 is used to place the funnel 4. A sufficient amount of metal powder is poured into the funnel 4, and the metal powder flows out of the funnel 4 flows out and accumulates on the transparent glass plate 6 until the metal powder increases to the bottom of the funnel 4 and forms a stable cone. The base 1 is provided with scale lines 5 in the x-axis and y-axis directions. The top of the base 1 is provided with a transparent glass plate 6. The transparent glass plate 6 is easy to clean and prevents contamination of the scale lines 5 on the upper surface of the base 1. Among them, the height h from the end surface of the bottom of the funnel 4 to the upper surface of the transparent glass plate 6 is used as the height of the cone and can be directly measured. The degrees x1 and x2 of the negative x-axis and the positive x-axis are read respectively through the x-axis, and the average value of x1 and x2 is taken as the first degree of the bottom circle of the cone. A radius r1, read the degrees y1 and y2 of the negative y-axis and the positive y-axis respectively through the y-axis, take the average value of y1 and y2 as the second radius r2 of the base circle of the cone, according to the height h from the end face of the bottom of the funnel 4 to the upper surface of the transparent glass plate 6 and the first radius r1 of the base circle of the cone, use the inverse trigonometric function to calculate the first natural slope angle θ1 in the x-axis direction, according to the height h from the end face of the bottom of the funnel 4 to the upper surface of the transparent glass plate 6 and the second radius r2 of the base circle of the cone, use the inverse trigonometric function to calculate the second natural slope angle θ2 in the y-axis direction, The average value of the first natural slope angle θ1 and the second natural slope angle θ2 is taken as the final natural slope angle θ; the center of the funnel 4 is perpendicular to the center of the scale line 5, and the intersection of the scale lines in the x-axis direction and the y-axis direction is the center of the scale line 5, so that the center of the cone falls on the center of the scale line 5; a baffle 8 is provided at the bottom of the funnel 4, and the baffle 8 is slidably connected to the funnel 4. Specifically, a slide groove for inserting the baffle 8 is provided at the bottom of the funnel 4, and the switch of the funnel 4 outlet is controlled by the baffle 8. A universal wheel 10 is provided at the bottom of the base 1 to facilitate the movement of the detection device for the natural slope angle of metal powder.
[0018] The working principle of this embodiment is as follows: when in use, the detection device for the natural slope angle of metal powder is placed on a horizontal ground, a sufficient amount of metal powder is put into the funnel 4, and after the baffle 8 is opened, the metal powder flows out of the funnel 4 and accumulates on the transparent glass plate 6 until the metal powder increases to the bottom end of the funnel 4 and forms a stable cone. The natural slope angle is calculated by the scale line 5 and the height from the end face of the bottom of the funnel 4 to the upper surface of the transparent glass plate 6. Therefore, the utility model does not need to be equipped with a special protractor and has a wide applicability; it does not need to be measured by visual inspection, which improves the accuracy of natural slope angle detection.
