Description

Technical Field

[0001] This utility model relates to the field of saw blade cutting technology, specifically a test device for bidirectional saw blade cutting. Background Technology

[0002] In the production and application of metal products, the metal coating (such as plating, coating, etc.) on the surface of the metal substrate plays a crucial role. It not only improves the appearance quality of metal products, but also enhances their corrosion resistance, wear resistance, and other properties. The adhesion strength between the metal coating and the metal substrate directly determines the effectiveness of the coating's function and the service life of the metal product. One method for testing the adhesion strength of metal coatings is the sawing method. The procedure is as follows: the tester holds a hacksaw and saw blade and saws from the substrate to the coating or from the coating to the substrate. During the sawing process, a certain sawing speed and sawing angle need to be controlled. After sawing, pressure-sensitive tape is used to stick to the sawed area, and then the tape is peeled off. The adhesion strength of the metal coating is judged by checking whether the coating has peeled off.

[0003] The existing technology of using a handheld saw to test the adhesion strength of metal coatings has drawbacks such as uncontrollable cutting angle, uncontrollable cutting depth, easy deviation of cutting direction, and low operational safety, which further leads to inaccurate test results.

[0004] Based on this, this utility model designs a two-way sawing test device for saw blades to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a test device for bidirectional cutting saw blade.

[0006] To achieve the above objectives, a two-way sawing test device for saw blades is designed, including a machine base, a fixed clamping assembly, a vertical moving assembly, and a horizontal fixed moving assembly; The machine is equipped with a clamping assembly for fixing the sample and a vertical moving assembly for vertical movement. The horizontal fixing and moving assembly is connected to the vertical moving assembly and is used for horizontal movement. The vertical moving component includes a supporting moving component and a mounting block. The supporting moving component is mounted on the machine base, and the mounting block is connected to the supporting moving component and to the horizontal fixed moving component. Furthermore, the supporting moving assembly includes a support frame, a slide rail, a slider, and a tension spring. The support frame is fixedly installed on the machine base, the slide rail is fixedly installed on the support frame, the slider is slidably connected to the slide rail and fixedly connected to the mounting block, one end of the tension spring is fixedly connected to the support frame, and the other end of the tension spring is connected to the horizontal fixed moving assembly.

[0007] Furthermore, the supporting moving assembly also includes an adjusting block and an adjusting bolt. The adjusting block is slidably connected to the slide rail, and the adjusting bolt is threadedly connected to the adjusting block and is used to press against the slide rail, thereby fixing the adjusting block.

[0008] Furthermore, the fixed clamping assembly includes a sample stage, clamping blocks, locking bolts, and anti-slip pads. The sample stage is fixedly installed on the machine base, and an anti-slip pad is fixedly installed on the sample stage. There are two clamping blocks, each with several threaded holes for the locking bolts to be threaded together. Similarly, several threaded holes for the locking bolts to be threaded together are also provided on the sample stage. The two locking bolts are first threadedly connected to the clamping blocks respectively, so that the clamping blocks are located above the locking bolts and then threadedly connected to the sample stage.

[0009] Furthermore, the horizontal fixed moving assembly includes a horizontal moving assembly and a clamping assembly. The horizontal moving assembly is mounted on the mounting block and is connected to the clamping assembly.

[0010] Furthermore, the horizontal moving component includes a mounting bracket, a second slide rail, and a second slider. The mounting bracket is fixedly mounted on the mounting block, the second slide rail is fixedly mounted on the mounting bracket, the second slider is slidably connected to the second slide rail, the second slider is connected to the clamping component and has multiple threaded holes for connecting to the clamping component, and the second slider is fixedly connected to the other end of the tension spring.

[0011] Furthermore, the clamping assembly includes a contour block and a fixing bolt. The contour block has multiple threaded holes that are threadedly connected to the fixing bolt. The fixing bolt is sequentially threadedly connected to the contour block and the slider.

[0012] Furthermore, the sample stage is positioned at a 45-degree angle to the horizontal plane, and a clearance groove is provided on the sample stage to avoid saw blade cutting.

[0013] Compared with the prior art, this utility model has the following advantages: (1) In this utility model, the vertical moving component and the horizontal fixed moving component are repeatedly and slowly pushed to test whether the vertical moving component and the horizontal fixed moving component move smoothly. After the test is smooth, the sample is placed on the fixed clamping component and the sample is fixed by the fixed clamping component. The saw blade clamping component is placed into the horizontal fixed moving component and fixed. The cutting depth required for the saw blade clamping component to cut the sample is adjusted by the supporting moving component. The saw blade clamping component is driven to move horizontally in one direction by the horizontal fixed moving component. After the cutting is completed, the vertical moving component is moved to lift the saw blade clamping component and cut again from the direction of the substrate. The saw blade clamping component always keeps the sample horizontally cut. At the same time, the operator does not need to hold the sample and the saw blade directly with his / her hand, which significantly improves the safety of the operation.

[0014] (2) By replacing the tension spring, the pre-compression of the tension spring can be adjusted, thereby adjusting the initial position of the slider one. By moving the slider one, the mounting block can be moved, thereby driving the horizontal fixed moving component to move vertically. The horizontal fixed moving component can drive the saw blade clamping component to cut the sample in the same direction, ensuring the consistency and stability of the cutting direction. At the same time, after each cut, the saw blade needs to be lifted, and the next cut can be started from the direction of the substrate. By the cooperation of the slide rail one and the slider one, the initial sawing position and angle of the saw blade can be ensured. At the same time, the tension spring has a buffering effect on the horizontal fixed moving component, which can prevent the saw blade on the saw blade clamping component from causing excessive impact on the sample during the downward sawing process, thus protecting the sample and the saw blade.

[0015] (3) By moving the adjustment block on the slide rail, the adjustment block is positioned at the position of the slider when the preset cutting depth is reached. The adjustment block is fixed by tightening the adjustment bolt. At this time, the slider moves vertically, which drives the horizontal fixed moving component to move vertically. When the saw blade clamping component cuts the sample to be tested, after cutting to the preset cutting depth, the bottom of the slider abuts against the adjustment block, thereby preventing the slider from cutting further downward, thus achieving precise control of the sample cutting depth.

[0016] (4) This utility model inserts the sample to be cut between the clamping block and the sample stage, rotates the locking bolt to make the clamping block press the sample to be cut against the sample stage and fix it, and further fixes the sample to be cut by the anti-slip pads on the clamping block and the sample stage, ensuring that the cutting angle between the saw blade and the sample is strictly controlled at 45 degrees during the test. The structure ensures the accuracy of the sawing angle, prevents the sample from sliding during the cutting process, and avoids the locking bolt from being over-tightened, which would cause damage to the sample surface.

[0017] (5) This utility model tests whether slider one and slider two run smoothly on slide rail one and slide rail two by repeatedly and slowly pushing slider one and slider two. After the test is smooth, insert the sample into the sample stage and clamping block, fix the sample position by tightening, replace the tension spring, thereby adjusting the pre-compression amount of the spring, and then adjust the initial position of slider one. By moving the position of the adjustment block on slide rail one, the adjustment block is positioned at the position of slider one when the preset cutting depth is reached. When slider one moves to the adjustment block, it is blocked by the adjustment block, thereby fixing the vertical movement distance of slider one. At this time, unscrew the fixing bolt and place the saw blade clamping assembly in the groove of slider two and the contour block. At this time, screw the fixing bolt into slider two to fix the saw blade clamping assembly. The saw blade clamping assembly can be adjusted according to different specifications of saw blades to fix the saw blade. Move slider two to drive the saw blade on the saw blade clamping assembly to cut the sample. After the cutting is completed, slider one needs to be moved to lift the saw blade and then start the next cutting from the direction of the substrate. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A two-way sawing test device for saw blades includes a machine base 1, and also includes a fixed clamping assembly 2, a vertical moving assembly 3 and a horizontal fixed moving assembly 4; A fixing clamping assembly 2 for fixing the sample and a vertical moving assembly 3 for vertical movement are installed on the machine 1. A horizontal fixing moving assembly 4 is connected to the vertical moving assembly 3 and is used for horizontal movement. The vertical moving component 3 includes a supporting moving component 31 and a mounting block 32. The supporting moving component 31 is mounted on the machine base 1, and the mounting block 32 is connected to the supporting moving component 31 and to the horizontal fixed moving component 4.

[0020] In this invention, the vertical moving component 3 and the horizontal fixed moving component 4 are repeatedly and slowly pushed to test whether the vertical moving component 3 and the horizontal fixed moving component 4 move smoothly. After the test is smooth, the sample is placed on the fixed clamping component 2 and fixed by the fixed clamping component 2. The saw blade clamping component 5 is placed into the horizontal fixed moving component 4 and fixed. The cutting depth required for the saw blade clamping component 5 to cut the sample is adjusted by the supporting moving component 31. The horizontal fixed moving component 4 drives the saw blade clamping component 5 to move horizontally in one direction. After the cutting is completed, the vertical moving component 3 is moved to lift the saw blade clamping component 5 and cut again from the direction of the substrate. This ensures that the saw blade clamping component 5 always keeps the sample horizontally during cutting. At the same time, the operator does not need to hold the sample and saw blade directly with their hands, which significantly improves the safety of operation.

[0021] The supporting moving assembly 31 includes a support frame 311, a slide rail 312, a slider 313, and a tension spring 314. The support frame 311 is fixedly installed on the machine base 1, the slide rail 312 is fixedly installed on the support frame 311, the slider 313 is slidably connected to the slide rail 312 and is fixedly connected to the mounting block 32, one end of the tension spring 314 is fixedly connected to the support frame 311, and the other end of the tension spring 314 is connected to the horizontal fixed moving assembly 4.

[0022] In this embodiment, the support frame 311 is provided with a scale for easy reading.

[0023] In this invention, by replacing the tension spring 314, the pre-compression of the tension spring is adjusted, thereby adjusting the initial position of the slider 313. Moving the slider 313 drives the mounting block 32 to move, which in turn drives the horizontal fixed moving assembly 4 to move vertically. The horizontal fixed moving assembly 4 drives the saw blade clamping assembly 5 to cut the sample in a consistent direction, ensuring the consistency and stability of the cutting direction. After each cut, the saw blade needs to be lifted, and the next cut can start from the direction of the substrate. The cooperation between the slide rail 312 and the slider 313 ensures the initial sawing position and angle of the saw blade. At the same time, the tension spring 314 has a buffering effect on the horizontal fixed moving assembly 4, which can prevent the saw blade on the saw blade clamping assembly 5 from causing excessive impact on the sample during the downward sawing process, thus protecting the sample and the saw blade.

[0024] Example 2: The supporting moving component 31 further includes an adjusting block 315 and an adjusting bolt 316. The adjusting block 315 is slidably connected to the slide rail 312, and the adjusting bolt 316 is threadedly connected to the adjusting block 315 and is used to press against the slide rail 312, thereby fixing the adjusting block 315.

[0025] In this invention, by moving the adjustment block 315 to the position of the slide rail 312, the adjustment block 315 is positioned at the position of the slider 313 at the preset cutting depth. The adjustment block 315 is fixed by tightening the adjustment bolt 316. At this time, moving the slider 313 drives the horizontal fixed moving component 4 to move vertically, thereby driving the saw blade clamping component 5 to cut the sample to be tested. After cutting to the preset cutting depth, the bottom of the slider 313 abuts against the adjustment block 315, thereby preventing the slider 313 from continuing to cut downwards, thus achieving precise control of the sample cutting depth.

[0026] The fixed clamping assembly 2 includes a sample stage 21, a clamping block 22, a locking bolt 23, and an anti-slip pad 24. The sample stage 21 is fixedly installed on the machine base 1. The anti-slip pad 24 is fixedly installed on the sample stage 21. There are two clamping blocks 22, and each clamping block 22 has several threaded holes for threaded connection of the locking bolt 23. Similarly, the sample stage 21 has several threaded holes for connection of the locking bolt 23. The two locking bolts 23 are first threadedly connected to the clamping blocks 22 respectively, so that the clamping blocks 22 are located on the upper end of the locking bolts 23 and then threadedly connected to the sample stage 21.

[0027] In this embodiment, the placement surface of the sample stage 21 is at a 45-degree angle to the horizontal plane, and the sample stage 21 is provided with a clearance groove for avoiding saw blade cutting.

[0028] In this embodiment, an anti-slip pad 24 is fixedly installed on the contact surface between the clamping block 22 and the sample.

[0029] In this invention, the sample to be cut is inserted between the clamping block 22 and the sample stage 21, and the locking bolt 23 is rotated to make the clamping block 22 press the sample against the sample stage 21 and fix it. The anti-slip pads 24 on the clamping block 22 and the sample stage 21 further fix the sample to be cut, ensuring that the cutting angle between the saw blade and the sample is strictly controlled at 45 degrees during the test. The structure ensures the accuracy of the sawing angle, prevents the sample from sliding during the cutting process, and avoids the locking bolt 23 from being over-tightened, which would cause the clamping block 22 to damage the sample surface.

[0030] The horizontal fixed moving component 4 includes a horizontal moving component 41 and a clamping component 42. The horizontal moving component 41 is mounted on the mounting block 32 and is connected to the clamping component 42.

[0031] The horizontal moving component 41 includes a mounting bracket 411, a second slide rail 412, and a second slider 413. The mounting bracket 411 is fixedly mounted on the mounting block 32, the second slide rail 412 is fixedly mounted on the mounting bracket 411, the second slider 413 is slidably connected to the second slide rail 412, the second slider 413 is connected to the clamping component 42 and has multiple threaded holes for connecting to the clamping component 42, and the second slider 413 is fixedly connected to the other end of the tension spring 314.

[0032] The clamping assembly 42 includes a contour block 421 and a fixing bolt 422. The contour block 421 has multiple threaded holes that are threadedly connected to the fixing bolt 422. The fixing bolt 422 is threadedly connected to the contour block 421 and the slider 413 in sequence.

[0033] In this embodiment, the slider 413 has the same groove as the contour block 421.

[0034] In this embodiment, the mounting bracket 411 is provided with a scale for easy reading.

[0035] In this embodiment, the saw blade clamping assembly 5 adopts a Bestway adjustable hacksaw frame.

[0036] In this invention, the smoothness of sliders 313 and 413 running on slide rails 312 is tested by repeatedly and slowly pushing slider 313 and 413, respectively. After testing for smoothness, the sample is inserted into the sample stage 21 and clamping block 22. The sample position is fixed by tightening 23. The tension spring 314 is replaced to adjust the pre-compression of the spring, thereby adjusting the initial position of slider 313. The position of adjusting block 315 on slide rail 312 is moved so that adjusting block 315 is located at the position of slider 313 at the preset cutting depth. When slider 313 moves to adjusting block 315, The vertical movement distance of slider 1 313 is fixed by the adjustment block 315. At this time, the fixing bolt 422 is unscrewed, and the saw blade clamping assembly 5 is placed in the groove of slider 2 413 and contour block 421. Then, the fixing bolt 422 is screwed into slider 2 413 to fix the saw blade clamping assembly 5. The saw blade clamping assembly 5 can be adjusted according to different specifications of saw blades to fix the saw blade. Sliding slider 2 413 is moved to drive the saw blade on the saw blade clamping assembly 5 to cut the sample. After the cutting is completed, slider 1 313 needs to be moved to lift the saw blade and then start the next cutting from the direction of the substrate.
