Description

Technical Field

[0001] The invention belongs to the field of aluminum ingot product detection, and in particular relates to a finished product quality detection device for recycled aluminum ingot products. Background Art

[0002] Recycled aluminum ingots are aluminum alloy products made by recycling waste aluminum products and remelting them, then casting them. In the process of producing recycled aluminum ingots, it is necessary to conduct strict quality inspections on the produced recycled aluminum ingots, including chemical composition, density, mechanical properties, etc., to ensure that the products meet the standards required by customers.

[0003] When conducting tensile property testing on recycled aluminum ingot products, a tensile tester is mainly used for testing. However, the current tensile tester mainly stretches the two ends of the aluminum ingot by setting a certain tensile force value, and then measures the thickness change of the aluminum ingot to calculate its ductility. However, due to the different clamping positions at the two ends of the aluminum ingot, the center position where the thickness change is the smallest after the aluminum ingot is stretched to both sides is also different, so that the thickness change at the center position of the aluminum ingot cannot be accurately obtained. When measuring the thickness change, it is necessary to measure the symmetrical positions on both sides of the center point multiple times with a laser measuring instrument, and the result after a single measurement needs to be repeatedly checked and tested to ensure that the measured thickness change data is accurate. However, the above measurement method is cumbersome and inefficient, and it is difficult to ensure the accuracy and consistency of the symmetrical measurement positions of the center point.

At the same time, the cross plate 12 can be provided to support the recycled aluminum ingot product to be tested. The avoidance groove facilitates the tensile tester 4 to clamp and fix the two ends of the aluminum ingot product for tensile testing.

[0025] See also Figure 1 The limiting mechanism 2 includes a distance-adjusting screw 21 which is rotatably arranged on the front and rear inner walls of the rectangular sink 11 respectively, and the distance-adjusting screw 21 is provided with threads in opposite directions; two transverse limit plates 22 are symmetrically arranged on the distance-adjusting screw 21 by means of threaded connection, and the positions of the transverse limit plates 22 on the two distance-adjusting screws 21 correspond one to one; the two distance-adjusting screws 21 are connected together by a pulley transmission, and a motor 1 is connected to the end of any one of the distance-adjusting screws 21.

[0027] When the recycled aluminum ingot product to be tested is limited and fixed, the recycled aluminum ingot product to be tested is first placed on the cross plate 12, and then one of the adjustable pitch screws 21 is driven to rotate by motor 1, and then the other adjustable pitch screw 21 is driven to rotate synchronously with the pulley, and the two transverse limit plates 22 on the same adjustable pitch screw 21 approach each other until they hit the left and right side walls of the recycled aluminum ingot to be tested; then, the two-way adjustment screw 24 is driven to rotate by motor 2, and the two-way adjustment screw 24 controls the L-shaped longitudinal limit plates 23 on the front and rear sides to approach each other until they fit the front and rear side walls of the recycled aluminum ingot to be tested. In order to increase the friction with the surface of the aluminum ingot, rubber pads can be respectively set on the end faces of the transverse limit plates 22 and the L-shaped longitudinal limit plates 23 that fit the aluminum ingot.

[0028] In the present invention, by clamping and limiting in four directions, and by designing the front and rear directions and the left and right directions in a synchronous movement manner, the recycled aluminum ingot product placed on the cross plate 12 can be centered, so that the subsequent detection mechanism 3 can quickly find the center point position, thereby improving the detection efficiency and the accuracy of the detection results.

[0029] See also Figure 5 The L-shaped longitudinal limit plate 23 is composed of two straight plates fixed with bolts, one of which is threadedly connected to the bidirectional adjustment screw 24, and the other is in contact with the aluminum ingot product to be tested; in order to increase the detection data of the stretching center point of the aluminum ingot product, the straight plates on the front and rear sides that are respectively in contact with the aluminum ingot product to be tested can be replaced with straight plates of different widths to further improve the diversity of the detection results.

A positioning plate 32 is provided on the horizontal section of the inverted U-shaped frame 31 for sliding forward and backward. The positioning plate 32 can prevent the two U-shaped frames 35 from being separated from the upper end face of the recycled aluminum ingot product being detected when they move forward and backward toward each other; a bar-shaped through groove is also provided on the horizontal section of the inverted U-shaped frame 31, and a bidirectional lead screw 33 is provided for rotation inside the bar-shaped through groove, and one end of the bidirectional lead screw 33 passes through the bar The through slot is located outside the inverted U-shaped frame 31, and two moving bars 34 are threadedly connected to the bidirectional lead screw 33.

If the data on one side is consistent, it indicates that there is no error in the thickness detection, and then the data on both sides are compared. By comparing the data on both sides, it can be analyzed whether the tension is located at the tension point during stretching. Whether the thickness changes of the recycled aluminum ingot products on both sides of the stretching center line are consistent, and then the inverted U-shaped frame 31 is driven by the electric slider 13 to move horizontally to measure the thickness changes at the symmetrical positions in the left and right directions; at the same time, the left and right movement can obtain the thickness data of the distance from the stretching center point, which is convenient for subsequent analysis. After the horizontal movement is completed, continue to operate the rocker to drive the two-way screw 33 to rotate, and measure the thickness changes at the symmetrical positions in the front and rear directions. Finally, perform data processing and comprehensive analysis, combine data analysis to obtain the stretching change value, and compare it with the standard data to determine whether it meets the stretching quality requirements.
