Description

Technical Field

[0001] This utility model relates to the technical field of diamond wire saw testing equipment, specifically to a device for testing the surface adhesion and wear resistance of diamond wire saws. Background Technology

[0002] Diamond wire saws are wire cutting tools made by electrochemically depositing diamond abrasive onto the surface of steel wire using metallic nickel as a binder. They are widely used for cutting hard and brittle materials such as silicon wafers, sapphire, magnetic materials, ceramics, marble, and silicon carbide. Therefore, the bonding strength (firmness of bonding) between the diamond and steel wire surfaces and the wear resistance are important physical indicators for evaluating the cutting ability of diamond wire saws, and also important guiding principles for diamond wire saw production debugging and process development.

[0003] Currently, the industry's diamond wire saw performance testing equipment includes: tensile testing machines, torsion testing machines, microstructure analyzers, micrometers, microparticle size analyzers, microparticle shape analyzers, and diamond wire saw surface morphology analyzers. Surface bonding strength and wear resistance are crucial technical indicators for wire saws, and currently, testing relies on customer feedback or manual perception. There is no stable testing device, and existing verification methods suffer from the following problems:

[0004] (1) The production cycle of diamond wire is relatively long. To complete a roll of wire saw that meets the client's verification requirements, a long production and transportation cycle is needed. This results in a long and slow wire saw R&D and verification cycle. In addition, there are many variables and interference factors in the experimental verification process, and the communication cost is high.

[0005] (2) Manual touch test: The difference in the force, speed, angle and test material of each person's touch test will affect the premature peeling of the surface coating or the invalidation of the test, which will affect the judgment of the result.

[0006] (3) None of the above verification and testing methods can accurately set the testing parameters, form specific testing values, or form quantifiable comparison data results. Utility Model Content

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0038] This utility model provides a device for testing the surface adhesion and wear resistance of diamond wire saws, the testing device including a base 1.

[0039] like Figure 1 and Figure 2 As shown, the detection device includes a support plate 2, which includes a first support plate 21 and a second support plate 22. The support plate 2 can be fixed on the base 1, for example, it can be vertically fixed on the base 1. A vertical movement component 3 can be fixed on the first support plate 21.

[0040] The vertical motion component 3 includes a linear module 31, which is a prior art technology. Specifically, it can be driven by a motor to move a lead screw or a synchronous belt, thereby driving a slider connected to the lead screw or synchronous belt to move on a guide rail. Specifically, the linear module 31 includes a first slider 31a.

[0041] In some embodiments, the linear module 31 may be a KNK synchronous belt linear module.

The first sensing guide wheel 34b and the second sensing guide wheel 35b can detect the tension of the wire saw by converting the deformation caused by the external force applied to them when the diamond wire saw is wound around them into an electrical signal.

[0047] In some embodiments, the vertical motion component 3 includes a monitoring lens 33, which may be mounted on the connecting plate 32.

[0049] like Figure 3As shown, the lateral motion component 4 includes a drive motor 41 and a slide rail 42. One end of the drive motor 41 is fixed to one end of the slide rail 42. A second slider 43 is slidably connected to the slide rail 42. End plates 47 are provided at both ends of the slide rail 42. Through holes are provided on the end plates 47, and bearings 45 are provided at the through holes. The lateral motion component 4 includes a lateral lead screw 44.

[0051] like Figure 1 As shown, in some embodiments, the detection device further includes a control component 5, which includes a control cabinet. The bottom of the control cabinet is fixed on the base 1. The control cabinet can be a human-machine interface control cabinet, such as the Siemens KTP700 Basic model. The control component 5 can include a PLC controller located in the control cabinet, such as the Siemens S7-1200 PLC controller.

[0052] The control unit 5 can be electrically connected to the linear module 31, the drive motor 41, the first induction guide wheel 34b, the second induction guide wheel 35b, and the monitoring lens 33.

[0053] Example 1

[0054] The testing device of this invention was used to test 0.25mm diamond wire saws manufactured using two different processes, A and B, according to the following operating procedure:

[0055] 1. Take a 0.25mm diamond wire saw to be tested, manufactured using process A, and fix one end at the first clamping part 34.

[0056] 2. After fixing one end of the 0.25mm wire saw, pass it around the first induction guide wheel 34b and lead it to the second clamping member 35 on the lower side.

[0057] 3. After tightening the 0.25mm wire saw that passes over the lower second induction guide wheel 35b, fix it on the second locking buckle and remove the excess diamond wire saw.

[0058] 4. Select 800-mesh white fused alumina test material 100 with dimensions of 120*50*50, clamp it with clamp assembly 49, and adjust the angle to ensure that the side of the white fused alumina test material 100 is parallel to the wire saw.

[0059] 5. The human-machine interface on the control unit 5 is set to detect tension of 21N. The program controls the transverse motion component 4 to move the white corundum test material 100 close to the wire saw to be tested. When the electrical signal transmitted from the first induction guide wheel 34b and the second induction guide wheel 35b shows that the real-time test tension is 21N, the preset detection tension is reached, the transverse motion component 4 reaches the set position and stops moving.

[0060] 5. Operate the human-machine interface, set the test speed of the vertical motion component 3 to 200mm / s, preset the reciprocating frequency to 50 times, and start the detection switch.

[0061] Example 2

[0062] Using the same parameters, a wire saw manufactured by another process B was tested. After the test, the steel wire was compared and analyzed.

[0063] like Figures 5 to 8 As shown in the comparison and analysis, it is clear that process B has significant performance advantages and does not exhibit the same nickel layer peeling and flaking issues as process A.

[0064] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
