Description
Technical Field

[0002] The testing process of tension and compression usually involves the testing of brittle materials, such as rock wool boards and aerated blocks. In order to facilitate the testing work, the plate-like brittle materials (plates) are usually cut into several test blocks by a cutting machine, and then the test blocks are bonded with auxiliary plates and sent to the tension and compression device for tension and compression testing.
[0003] In the prior art, the cutting machine used is usually provided with a platform for fixing the plate, and a movable cutting assembly is provided under the platform. The saw blade in the cutting assembly extends upward through the opening on the platform, and the plate is cut as the cutting assembly moves (through two horizontal and vertical cutting, a number of test blocks are formed). Although this method can ensure the cutting of the test block, it involves brittle materials, which are easily broken after being subjected to external forces (after being subjected to the cutting force of the cutting saw blade, the plate has a slight vibration). The cutting surface of the test block finally produced is relatively rough, the flatness is poor, and the cutting effect of the test block is poor, which makes it inconvenient to bond the auxiliary plate later, and will also have a certain impact on the test data, and has poor practicality.

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0038] Please also read Figures 1 to 3 Now, the cutting device of the brittle test block provided by the utility model is described. The cutting device of the brittle test block comprises a machine base 10, a sliding clamping seat 20, a cutting structure 30 and a pressing structure 40. A gantry 11 is provided on the top of the machine base 10, and a slide rail portion 12 is provided on the machine base 10. The slide rail portion 12 is located at the bottom of the gantry 11 and passes through the gantry 11 horizontally. The sliding clamping seat 20 is slidably arranged on the slide rail portion 12, and the top of the sliding clamping seat 20 has a placement platform for fixing the plate 50. The cutting structure 30 is arranged on the gantry 11, and has a cutting portion that can move along the vertical direction. The cutting structure 30 can cut the plate 50 in the process of the sliding clamping seat 20 driving the plate 50 to pass through the gantry 11. The pressing structure 40 is arranged on the gantry 11, and has two pressing portions respectively located on both sides of the cutting portion. The pressing structure 40 can drive the two pressing portions to press on the upper plate surface of the plate 50 in the process of the plate 50 being cut.
[0039] Compared with the prior art, the cutting device for brittle test blocks provided in this embodiment is capable of clamping and fixing the plate 50 in the sliding clamping seat 20, thereby ensuring that the packaging material can move synchronously with it. The gantry 11 can ensure the fixed installation of the cutting structure 30 and the pressing structure 40. The cutting structure 30 can cut the plate 50 while the plate 50 moves with the sliding clamping seat 20. The two pressing parts on the pressing structure 40 can be pressed on the upper plate surface of the plate 50 on both sides of the cutting part, respectively, which can avoid vibration at the cutting position of the plate 50 after the plate 50 is affected by the cutting part, ensure the stability of the plate 50, and effectively ensure the flatness of the cutting surface. In addition, by moving the plate 50 to fix the cutting structure 30, it can also avoid to a certain extent the influence of the cutting effect on the cutting effect due to the vibration of the cutting structure 30, thereby ensuring the cutting effect, and having strong practicality.
[0040] In this embodiment, regarding the cutting of the test block, the plate 50 is first cut to obtain a spline, and then the spline is rotated 90° and the spline is cut to equal lengths by a cutting assembly to form a test block.
[0041] In some embodiments, the sliding clamping seat 20 can be used as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The sliding clamping seat 20 includes a sliding seat 21, a fixed baffle 22, a sliding baffle 23 and a first telescopic structure 24. The sliding seat 21 is slidably connected to the slide rail portion 12, and the end surface of the top of the sliding seat 21 is a placement platform. The fixed baffle 22 is arranged on the placement platform and is arranged along the length direction of the slide rail portion 12. The sliding baffle 23 is arranged parallel to the fixed baffle 22 and spaced apart, and a clamping space for placing the plate 50 is formed between the sliding baffle 23 and the fixed baffle 22. The first telescopic structure 24 can drive the sliding baffle 23 to move relative to or away from the fixed baffle 22.
[0042] The slide 21 can ensure that the plate 50 is driven to move on the slide rail 12. The slide 21 can be driven by manual pushing and pulling, or by a screw transmission structure arranged under the machine base 10. The above methods are all existing technologies and will not be repeated here. The first telescopic structure 24 can drive the sliding baffle 23 to move closer to or away from the fixed baffle 22 to adapt to plates 50 of different sizes, and can ensure that the plate 50 is clamped and fixed in two directions, thereby ensuring that the plate 50 is stably fixed on the placement platform.
[0043] In this embodiment, the distance between the fixed baffle 22 and the cutting portion can be fixed to serve as one or more dimensions of the test block. Specifically, the fixed baffle 22 can be adjusted by an adjustment screw disposed on the slide 21 to adjust the distance between the fixed baffle 22 and the cutting portion.
[0044] In addition, it should be noted that an auxiliary stopper may be provided at one end of the slide 21, and the auxiliary stopper may be fixed on the slide 21, and may abut against one end of the plate 50 in the length direction of the slide rail 12 to limit the plate 50 in another direction, thereby further ensuring the stability of the plate 50. In the cutting process adopted at this time, the slide 21 needs to be pushed at one end of the auxiliary stopper.
[0045] In some embodiments, the first telescopic structure 24 may be configured as follows: Figure 2 See the structure shown. Figure 2There are multiple first telescopic structures 24, and each first telescopic structure 24 is arranged at intervals along the length direction of the slide rail portion 12. Multiple first telescopic structures 24 can ensure precise adjustment of the sliding baffle 23 and ensure that the sliding baffle 23 is evenly stressed. The first telescopic structure 24 can be an electric cylinder.
[0046] In some embodiments, the cutting structure 30 may be implemented as follows: Figure 1 and Figure 2 See the structure shown. Figure 1 and Figure 2 The cutting structure 30 includes a lifting seat 31, a second telescopic structure 32, a cutting saw blade 33 and a driver 34. The lifting seat 31 is arranged in the gantry 11. The second telescopic structure 32 is fixed on the gantry 11 and connected to the lifting, and can drive the lifting seat 31 to move up and down. The cutting saw blade 33 is rotatably arranged on the lifting seat 31, and the rotation axis is arranged along the horizontal direction perpendicular to the length direction of the slide rail part 12, and the bottom end of the cutting saw blade 33 is the cutting part. The driver 34 is arranged on the lifting seat 31, and can drive the cutting saw blade 33 to rotate.
[0047] The second telescopic structure 32 drives the lifting seat 31 downward so that the cutting saw blade 33 passes through the plate 50. At the same time, the cutting saw blade 33 rotates under the drive of the driver 34 to ensure the cutting of the plate 50. This cutting method has a simple structure, is easy to manufacture, has a good cutting effect, and can quickly adjust the cutting depth.
[0048] In this embodiment, the lifting seat 31 can be connected to the gantry 11 in a limited sliding manner along the vertical direction. Specifically, two guide rods can be set on the lifting seat 31. The two guide rods are set along the vertical direction and are located on both sides of the cutting saw blade 33. The top of each guide rod is slidably connected to the gantry 11, which can effectively ensure the sliding stability of the lifting seat 31, thereby ensuring the stability of the cutting saw blade 33 during operation and ensuring the flatness of the cutting surface.
[0049] In some embodiments, the above-mentioned placement platform can be used as follows Figure 1 See the structure shown. Figure 1 A long groove corresponding to the cutting saw blade 33 is provided on the mounting platform. The setting of the long groove can ensure the insertion of the bottom end of the cutting saw blade 33, thereby ensuring that the plate 50 is completely cut off, while also avoiding interference between the cutting saw blade 33 and the slide seat 21, and effectively protecting the cutting saw blade 33.
[0050] In some embodiments, the above-mentioned pressing structure 40 can be adopted as follows Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2The pressing structure 40 includes a lifting plate 41, a third telescopic structure 42, a vertical plate 43 and a pressure wheel group. The lifting plate 41 is arranged in the gantry 11 and is located below the lifting seat 31. The lifting plate 41 is provided with a long strip opening 45 for the cutting saw blade 33 to pass through. There are two third telescopic structures 42, and the two third telescopic structures 42 are respectively located on both sides of the lifting seat 31, and are both fixed on the gantry 11 and connected to the lifting plate 41, and can drive the lifting plate 41 to move up and down. There are two vertical plates 43, and the two vertical plates 43 are fixed at the bottom end of the lifting plate 41 and are respectively located on both sides of the long strip opening 45. There are two pressure wheel groups, and the two pressure wheel groups are respectively arranged on the two vertical plates 43. Each pressure wheel group includes a plurality of pressure rollers 44, and each pressure roller 44 is rotatably arranged on the corresponding vertical plate 43, and the rotation axis is arranged along the horizontal direction perpendicular to the length direction of the slide rail part 12. The bottom ends of the pressure wheels in each pressure wheel group are combined to form a pressure setting part.
[0051] The lifting plate 41 is located below the lifting seat 31, which can avoid interference between the lifting plate 41 and the lifting seat 31, and the third telescopic structure 42 drives the lifting plate 41 to move up and down, which can ensure that the pressure wheel group is separated from or abuts against the plate 50, and can also adapt to plates 50 of different thicknesses. The setting of the vertical plate 43 can ensure the installation of the pressure wheel group, and the two pressure wheel groups are respectively located on both sides of the long strip opening 45, which can ensure that the plate 50 is pressed on both sides of the cutting saw blade 33 during the working process of the cutting saw blade 33, avoiding large vibration at the cutting position, and also preventing the top surface of the plate 50 from being cracked by the cutting saw blade 33. The structure is simple, the operation is convenient, and the practicability is strong.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
