Description

Technical Field

[0001] The utility model relates to the technical field of forging experimental equipment, in particular to an experimental device for powder forging workpieces. Background Art

[0002] Powder forging generally refers to a forming process in which a preform of sintered powder is heated and then forged into a part in a closed die. It is a new process that combines traditional powder metallurgy with precision forging, combining the advantages of both. It can produce powder forgings with densities close to the theoretical density of the material, overcoming the low density disadvantage of conventional powder metallurgy parts. Certain physical and mechanical properties of powder forgings reach or even exceed those of conventional forgings, while retaining the advantages of conventional powder metallurgy processes, such as low-chip or zero-chip production. Through the rational design of the preform and the implementation of low-flash or zero-flash forging, it achieves precise forming, high material utilization, and low forging energy consumption.

[0003] Powder forged workpieces produced through powder forging require surface hardness testing. Before testing with a Vickers hardness tester, the surface must be polished to remove impurities, oxide layers, or coatings to ensure accurate and reliable testing. Polishing involves selecting the appropriate polishing tool, following the correct polishing procedures, and paying attention to the surface quality and cleanliness after polishing. In industrial production, the Vickers hardness tester is an important tool for measuring the surface hardness of materials. To ensure accurate and reliable test results, the surface must be polished before testing.

[0004] During the experimental stage, the powder forging workpiece is usually manually polished, which makes it difficult to remove surface impurities, oxide layers or coatings, resulting in deviations in the experimental test data. Utility Model Content

[0023] The following is a combination of the embodiments of the present invention Figure 1-Figure 3 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0024] An experimental device for powder forging a workpiece, specifically comprising a base 1, on which a first mounting plate 2 and a second mounting plate 3 are vertically spaced apart, and a first plane grinding assembly and a second plane grinding assembly are symmetrically arranged at ends of the first mounting plate 2 and the second mounting plate 3 facing each other;

[0025] The first plane grinding assembly includes a first shaft 4 and two second shafts 5 arranged above the first shaft 4, the two second shafts 5 are arranged horizontally at intervals, the first shaft 4 and the second shaft 5 are arranged between the first mounting plate 2 and the second mounting plate 3, and the two second shafts 5 are rotatably sleeved with a first slide 6, the first shaft 4 and the two first slides 6 are sleeved with a first grinding belt 7, and the first mounting plate 2 is provided with a first motor 8 for driving the first shaft 4 to rotate;

[0026] The second plane grinding assembly includes a third shaft 9 and two fourth shafts 10 arranged below the third shaft 9, the two fourth shafts 10 are arranged horizontally and spaced apart, and a second slide 11 is rotatably sleeved on the two fourth shafts 10, and a second grinding belt 12 is sleeved on the third shaft 9 and the two second slides 11, and a second motor 13 for driving the third shaft 9 to rotate is provided on the second mounting plate 3;

[0027] The lower end of the second grinding belt 12 and the upper end of the first grinding belt 7 form a grinding section.

[0028] The upper and lower surfaces of the powder forging workpiece are polished simultaneously by the first plane polishing assembly and the second plane polishing assembly which are symmetrically arranged up and down. Compared with manual polishing, it is not only more labor-saving and eliminates bottoming, but also can perform double-sided polishing, thereby improving the polishing efficiency and also helping to improve the accuracy of experimental testing of the powder forging workpiece.

[0029] Specifically, the first motor 8 drives the first shaft 4 to rotate, the first shaft 4 drives the first grinding belt 7 to rotate, and the second motor 13 drives the third shaft 9 to rotate, and the third shaft 9 drives the second grinding belt 12 to rotate, and the powder forging workpiece is placed in the grinding interval between the first grinding belt 7 and the second grinding belt 12, and the upper and lower surfaces of the powder forging workpiece are simultaneously ground by the first grinding belt 7 and the second grinding belt 12, so as to facilitate the subsequent experimental detection of the surface hardness of the powder forging workpiece by a Vickers hardness tester.

[0030] The second mounting plate 3 includes an upper plate 14 and a lower plate 15 connected to the upper plate 14. The lower end of the upper plate 14 is provided with a slide groove, and the upper end of the lower plate 15 is slidably set in the slide groove. The upper plate 14 is vertically provided with a plurality of first screw holes arranged at intervals. The upper plate 14 is provided with a bolt 16, and the bolt 16 is threaded through the first screw hole and conflicts with the lower plate 15.

[0031] When it is necessary to grind the surface of powder forging workpieces of different thicknesses, it is necessary to adjust the upper and lower positions of the second grinding belt 12. Specifically, the upper plate 14 is slid in the slide groove of the lower plate 15 until the second grinding belt 12 is adjusted to a suitable position, and then the bolt 16 is passed through the first screw hole and the bolt 16 is tightly in contact with the upper plate 14 to prevent the upper plate 14 and the lower plate 15 from sliding relative to each other.

[0032] The upper plate 14 and the first mounting plate 2 are both provided with a tension adjustment assembly;

[0033] The tension adjustment assembly includes a concave-shaped frame plate 17, a roller 18 rotatably disposed within the frame plate 17, a fixing plate 19 and a screw 20 disposed on one side of the frame plate 17, a second screw hole disposed on the fixing plate 19, one end of the screw 20 threadedly passing through the second screw hole and connected to the frame plate 17, and a nut 21 threadedly connected to the other end;

[0034] The two fixing plates 19 are fixedly connected to the upper plate 14 and the first mounting plate 2 respectively, and the two rollers 18 are respectively in contact with the first grinding belt 7 and the second grinding belt 12.

[0035] The frame plate 17 is moved by rotating the screw 20 until the roller 18 conflicts with the adjacent first grinding belt 7 or the second grinding belt 12, and is threadedly connected to the screw 20 through the nut 21, and the spiral is adjusted to conflict with the fixed plate 19. At this time, the tightness adjustment of the first grinding belt 7 and the second grinding belt is completed, which facilitates the first grinding belt 7 and the first shaft 4 to be closely connected, and at the same time facilitates increasing the friction between the first grinding belt 7 and the first shaft 4, so that the first shaft 4 drives the first grinding belt 7 to rotate. Similarly, the second grinding belt 12 and the third shaft 9 are closely connected, which facilitates increasing the friction between the second grinding belt 12 and the third shaft 9, so that the third shaft 9 drives the second grinding belt 12 to rotate.

[0036] Example 2:

[0037] The first mounting plate 2 and the second mounting plate 3 are both provided with a support plate 22 . The two support plates 22 are used to install the first motor 8 and the second motor 13 , respectively. The first motor 8 and the second motor 13 are fixed to the two support plates 22 by bolts 16 , respectively.

[0038] The upper end of the first grinding belt 7 and the lower end of the second grinding belt 12 are arranged in parallel, so as to facilitate grinding the upper and lower surfaces of the powder forging workpiece.

[0039] The third shaft 9 and the fourth shaft 10 are both provided with a limiting disc 23 at one end away from the upper plate 14 . The setting of the limiting disc 23 prevents the second grinding belt 12 from being separated from the third shaft 9 and the fourth shaft 10 .

[0040] The surface roughness of the first grinding belt 7 and the second grinding belt 12 is consistent, which is convenient for grinding the upper and lower surfaces of the powder forging workpiece to the same degree and facilitating test comparison.

[0041] The surface roughness of the first grinding belt 7 and the second grinding belt 12 are different, which facilitates the study and comparison of the grinding effects of grinding belts with different roughness on powder forging workpieces.

[0042] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various deformations, modifications, and substitutions of the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
