Description

Technical Field

[0001] This utility model relates to the field of lubricant testing, and in particular to a device for testing the performance of wet-stretch lubricants. Background Technology

[0002] The wet drawing lubricant performance testing device is a specialized device used to evaluate the various properties of lubricants in the wet drawing process. Its core functions include testing the extreme pressure properties, friction reduction properties, wear resistance, temperature stability, and protective ability of the lubricant on the metal surface.

[0003] The existing wet-stretch lubricant performance testing equipment is mainly a four-ball friction and wear tester. However, when the four-ball friction and wear tester tests the performance of lubricating oil under different temperature conditions, it only heats the lubricating oil through the heating device inside the oil box. The heating time is long and the temperature of the lubricating oil rises unevenly, which affects the test results.

[0004] Therefore, it is necessary to provide a new wet-stretching lubricant performance testing device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wet-stretch lubricant performance testing device, which solves the problem that heating the lubricating oil solely through the heating device inside the oil box results in a long heating time and uneven temperature rise of the lubricating oil, thus affecting the test results.

[0006] The wet-stretch lubricant performance testing device provided by this utility model includes a test bench, a testing mechanism installed on the test bench, a constant temperature heating platform installed on the test bench, and a preheating tank placed on the constant temperature heating platform.

[0007] Two uprights are symmetrically fixed on the test stand. A pump body is fixed on one side of each upright. The inlet end of the pump body is connected to the preheating tank through a hose, and the outlet end of the pump body is connected to the top side of the oil box in the detection mechanism through a hose.

[0008] In a preferred embodiment, a stirring shaft is movably installed inside the preheating tank, and several stirring blades are fixed on the stirring shaft.

[0009] In a preferred embodiment, the top of the stirring shaft extends out of the preheating tank and is fixed with a crank handle.

[0010] In a preferred embodiment, a first arc-shaped positioning plate is fixed on one of the uprights, and a plurality of sliding columns are provided through the other upright, with a second arc-shaped positioning plate fixed on the sliding columns. The preheating tank is located between the first arc-shaped positioning plate and the second arc-shaped positioning plate.

[0011] In a preferred embodiment, a threaded sleeve is provided through the support, the threaded sleeve is movably connected to the support, and a tightening screw is threadedly provided at the threaded sleeve, one end of the tightening screw being fixedly connected to the second arc-shaped positioning plate.

[0012] In a preferred embodiment, a hexagonal block is fixed on the threaded sleeve.

[0013] The beneficial effects of this utility model are:

[0014] Before adding lubricant at a certain temperature into the oil box, the tester can first pour the lubricant into the preheating tank, start the constant temperature heating platform to heat the preheating tank, and turn the crank to drive the stirring shaft to rotate. Stirring the lubricant can ensure that its temperature rises evenly. When the temperature of the lubricant in the preheating tank reaches the required value, start the pump to draw the lubricant into the oil box through the hose. By uniformly heating the lubricant to be tested in advance, the accuracy of the test results is further improved.

[0015] The preheating tank can be effectively fixed by two arc-shaped positioning plates, ensuring that the preheating tank will not shake during stirring. When it is necessary to clean the preheating tank, simply use a wrench to turn the hexagonal block to remove the limiting action on the preheating tank and remove it. The operation is simple and convenient. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 The main structure of the wet-stretching lubricant performance testing device provided by this utility model is shown in stereoscopic view. Figure 1 ; Figure 2 The main structure of the wet-stretching lubricant performance testing device provided by this utility model is shown in stereoscopic view. Figure 2 ; Figure 3 for Figure 2 The diagram shows an enlarged structural representation of A.

[0022] In the specific implementation process, such as Figures 1-3 As shown, it includes a test bench 1, on which a testing mechanism 2 is installed. Since the testing mechanism 2 is a very mature technology in this field, its specific working principle will not be described in detail here. Those skilled in the art can refer to the existing four-ball friction and wear testing machine.

[0023] A constant temperature heating platform 3 is installed on the test platform 1. A preheating tank 4 is placed on the constant temperature heating platform 3. The top of the preheating tank 4 is closed and a liquid inlet / outlet is reserved. A stirring shaft 8 is installed inside the preheating tank 4. Several stirring blades 9 are fixed on the stirring shaft 8. The top of the stirring shaft 8 extends out of the preheating tank 4 and is fixed with a hand crank 10. Turning the hand crank 10 drives the stirring shaft 8 and several stirring blades 9 to rotate, which can stir the lubricant inside the preheating tank 4.

[0024] Two uprights 5 are symmetrically fixed on the test bench 1. A pump body 6 is fixed on one side of the uprights 5. The inlet end of the pump body 6 is connected to the preheating tank 4 through a hose, and the outlet end of the pump body 6 is connected to the top side of the oil box 7 in the detection mechanism 2 through a hose.

[0025] One of the support bases 5 is fixed with a first arc-shaped positioning plate 11, and the other support base 5 is provided with multiple sliding columns 12. A second arc-shaped positioning plate 13 is fixed on the sliding column 12. The preheating tank 4 is located between the first arc-shaped positioning plate 11 and the second arc-shaped positioning plate 13. A threaded sleeve 14 is provided through the support base 5 and is movably connected to the support base 5. A tightening screw 15 is threaded on the threaded sleeve 14. One end of the tightening screw 15 is fixedly connected to the second arc-shaped positioning plate 13. A hexagonal block 16 is fixed on the threaded sleeve 14. When the preheating tank 4 needs to be cleaned, the hexagonal block 16 is turned with a wrench to rotate the threaded sleeve 14. Under the rotation of the threaded sleeve 14, the tightening screw 15 drives the second arc-shaped positioning plate 13 to move along the direction of the sliding column 12, thus canceling the limiting work on the preheating tank 4. The installation of the preheating tank 4 is the same.

[0026] The working principle of this utility model is as follows: Before adding lubricant at a certain temperature into the oil box 7, the tester can first pour the lubricant into the preheating tank 4, start the constant temperature heating platform 3 to heat the preheating tank 4, and at the same time, turn the hand crank 10 to drive the stirring shaft 8 to rotate. By stirring the lubricant, its temperature can be raised evenly. When the temperature of the lubricant in the preheating tank 4 rises to the required value, start the pump body 6 to draw the lubricant into the oil box 7 along the hose, which further improves the accuracy of the test results.

[0027] The preheating tank 4 can be effectively fixed by two arc-shaped positioning plates to ensure that the preheating tank 4 will not shake during stirring. When the preheating tank 4 needs to be cleaned, use a wrench to turn the hexagonal block 16 to drive the threaded sleeve 14 to rotate. Under the rotation of the threaded sleeve 14, the tightening screw 15 drives the second arc-shaped positioning plate 13 to move along the direction of the sliding column 12, thus canceling the limiting work on the preheating tank 4. The same method applies to installing the preheating tank 4.

[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
