AI Technical Summary
In the measurement of elongation of aluminum alloy samples, irregular arc and elasticity of the samples lead to unstable marking, with large errors in the pitch points, which affects the accuracy of the test.
An aluminum alloy rectangular sample marking drill is designed, including a handle, a marking wheel and a marking tooth tip. By flattening the handle along the center line of the sample and moving the marking drill, the marking wheel moves smoothly to ensure that the marking points are evenly placed on the test piece. The surface of the sample should be flattened to avoid deformation affecting the marking accuracy.
It achieves uniform and precise marking on the surface of the sample, improves the quality of tensile sample preparation and test performance indicators, and solves the problems of unstable marking and large errors.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum alloy production, in particular to an aluminum alloy rectangular sample marking drill. Background Art
[0002] The elongation of materials is an important indicator of product quality. The elongation is mainly measured and calculated by tensile test. Before measurement, the test sample must be evenly marked with dots, and the change between the gauge lengths before and after stretching must be measured to calculate the elongation. Therefore, whether the dots on the sample are even and whether the dots are well marked directly affects the measurement of the material's elongation. At present, when measuring elongation, the dots on the sample are generally marked manually or by a marking machine. Manual marking usually involves placing the sample in a sample slot, selecting a dot drill that matches the gauge length, aligning the dot drill with the sample, and using a hand hammer to mark the dots. Marking by a marking machine usually involves placing the sample in a sample slot of the marking machine, turning on the marking machine to automatically mark the dots. However, in actual marking, the quenched sample cannot be pressed flat, and the processed rectangular sample will also present an irregular arc shape when released, making the sample arc-shaped and elastic. When manual marking is used, the sample is very easy to splash and slip, resulting in low marking efficiency; when a marking machine is used for marking, the irregular arc on the sample causes different degrees of protrusions between the marking points when the marking head is pressed down, resulting in the actual distance between the marking points being greater than the marking point spacing, resulting in the inability to accurately reflect the tensile extension length during the test measurement. Therefore, in order to eliminate the influence of the irregular arc shape and its own elasticity of the sample on the marking accuracy, it is necessary to further optimize the marking device of the aluminum alloy sample to ensure the accuracy of the tensile test. Utility Model Content
[0003] The utility model provides an aluminum alloy rectangular sample marking drill to solve the problems existing in the above background.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The utility model discloses an aluminum alloy rectangular sample marking drill, comprising a handle, a marking wheel rotatably provided on the handle, and a plurality of marking tooth tips evenly distributed on the circumferential side of the marking wheel.
[0006] Furthermore, a mounting cavity is provided in the center of the handle, screws are provided on both sides of the mounting cavity and pass through the handle, bearings are sleeved on the circumferential side of the screws, and the punctuation wheel is fixedly sleeved on the circumferential side of the bearings.
[0007] Furthermore, a plurality of through holes are symmetrically and evenly distributed on both sides of the handle.
[0008] The utility model has the following beneficial effects:
[0009] The utility model provides an aluminum alloy rectangular sample marking drill, which is mainly composed of a handle, a mounting cavity, a marking wheel, a screw and marking tooth tips. The handle is flattened along the center line of the sample and the marking drill is moved as a whole, so that the marking wheel moves smoothly along the center line of the sample, thereby ensuring that the marking tooth tips with preset spacings evenly mark the marks on the sample surface, and at the same time effectively flattens the sample, avoiding the influence of sample deformation on the accuracy of the marking process, thereby improving the overall quality of tensile sample preparation and the performance indicators of the test, and solving the problem that when conducting elongation measurement tests on aluminum alloy samples, the commonly used marking method is often affected by factors such as sample deformation when marking the sample, resulting in unstable sample slipping and large error in the spacing between marking points, resulting in reduced accuracy of the sample when conducting tensile tests.
[0010] The provision of the through hole in the utility model effectively reduces the overall weight of the marking drill, thereby improving the overall application convenience of the marking drill.
[0011] The installation of the screw and the bearing on the marking wheel in the utility model effectively improves the convenience of disassembly and assembly of the marking drill as a whole, thereby improving the practicality of the marking drill as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0016] like Figure 1 As shown, an aluminum alloy rectangular sample marking drill comprises a handle 1, on which a marking wheel 4 is rotatably mounted, and a plurality of marking tooth tips 7 are evenly welded on the circumferential side of the marking wheel 4.
[0017] A mounting cavity 3 is provided in the center of the handle 1 , and screws 5 are installed on both sides of the mounting cavity 3 and through the handle 1 . A bearing 6 is welded and installed on the circumferential side sleeve of the screw 5 , and the punctuation wheel 4 is fixedly welded and sleeved on the circumferential side of the bearing 6 .
[0018] A plurality of through holes 2 are symmetrically and evenly distributed on both sides of the handle 1 .
[0019] When the utility model is used in a specific application, the marking drill is pre-checked to be well installed as a whole, and then the processed high-strength thin-walled pipe rectangular sample is placed flat on the test table, the marking drill is picked up in a direction parallel to the sample, the marking wheel 4 is aligned with the center line of one side of the sample, both hands are held on the handles 1 on both sides, and while pressing down hard, it moves along the center line of the sample toward the other end of the sample. During the movement, the marking tooth tip 7 evenly marks the marks on the sample, and the sample is flattened during the marking process, which effectively eliminates the influence of the irregular arc shape and the elasticity of the sample on the marking accuracy, and can efficiently mark the marks with accurate preset spacing. After the marking is completed, the tensile test and the elongation measuring machine are calculated, which effectively improves the overall quality of the tensile sample preparation and the performance index of the test. Therefore, the marking drill has good practicality.
