[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.
[0028] Soft metals, such as aluminum alloys after thermoplastic deformation, for example, 6 series aluminum alloys, are very soft products. The Webster hardness before cutting into fixed lengths is generally ≤5. Burrs are likely to remain on the end after sawing. In order to ensure that the aluminum alloy can meet the use requirements after sawing, it is necessary to place it on a grinding machine or other equipment for grinding to remove the residual burrs. The manufacturing process is relatively complicated and the manufacturing cost is relatively high. The same saw blade has no burrs on the profile after aging, which means that the residual burrs on the end are mainly affected by the low hardness of the profile. The embodiment of the utility model provides a saw blade for sawing the end face of soft metal. In this process, the end face burrs can also be removed, as described below.
[0029] The utility model provides a saw blade, taking the saw blade for processing the end face of an aluminum profile as an example. Figure 1-Figure 2 As shown, the saw blade includes: a saw body 100, saw teeth 200, and a grinding layer 300; the saw body 100 is a disc-shaped structure; the saw teeth 200 are fixedly arranged on the outer peripheral side of the saw body 100, and the end faces of the saw teeth 200 are arranged at an obtuse angle to the end faces of the saw body 100, and the thickness of the outer edge of the saw teeth 200 is greater than the thickness of the saw body 100; the grinding layer 300 is fixedly arranged on the end face of the saw body 100, and the end face of the saw body 100 is arranged at an obtuse angle to the surface of the grinding layer 300; projected along the radial direction of the saw body 100, the end edge of the saw tooth 200 can be projected onto the surface of the grinding layer 300.
[0030] In the embodiment of the utility model, the end face of the saw tooth 200 is set at an obtuse angle with the end face of the saw body 100, so the edge of the saw tooth 200 protrudes from the end face of the saw body 100 on the same side, the grinding layer 300 is fixed to the end face of the saw body 100 and is set at an obtuse angle with the end face, and is projected along the radial direction of the saw body 100 onto the axis of the saw body 100, and the projection of the outer edge of the saw tooth 200 falls into the projection of the grinding layer. In this way, the end face of the saw tooth 200 and the grinding layer are arranged. The surfaces of 300 are inclined relative to the end faces of the saw body 100, and the inclination directions are opposite, that is, the end faces of the saw tooth 200, the end faces of the saw body 100, and the surface of the grinding layer 300 form a trapezoidal groove structure, and the end face of the saw body 100 is located at the bottom of the trapezoidal groove, the end face of the saw tooth 200 and the surface of the grinding layer 300 are two opposite inner wall surfaces of the trapezoidal groove, the opening size of the groove is larger than the bottom size of the groove, and the extension height of the grinding layer 300 is larger than the extension height of the saw tooth. During use, the saw teeth 200 cut the end face of the aluminum product. During this processing, there is a gap between the end face of the saw body 100 and the end face of the aluminum product to be cut and the end face of the aluminum product after cutting, so there is no adverse effect such as wear on the end face of the saw body 100. When cutting to a certain depth, the burrs and other protrusions on the end face of the aluminum product after cutting can be ground off after contacting the grinding layer 300, thereby achieving simultaneous cutting and grinding deburring. Obviously, compared with the prior art that the cut aluminum product must be placed in a special grinding device, the saw blade provided by the embodiment of the utility model does not need to place the cut aluminum product in other grinding equipment, and burrs are removed simultaneously during the process of cutting the end face, which not only simplifies the processing technology, but also reduces the processing cost and improves the processing efficiency.
[0031] It should be noted that the saw blade provided in the embodiment of the utility model can not only cut aluminum products, but also cut other soft metals, which is not limited here.
[0032] Specifically, in the embodiment of the present utility model, Figure 1 As shown, the root of the saw tooth 200 is flush with the end surface of the saw body 100 .
[0033] In the embodiment of the utility model, Figure 1 As shown, the middle area of the saw body 100 has a groove, one end of the grinding layer 300 is fixedly embedded in the groove, and the other end protrudes from the end surface of the saw body 100. In this way, the groove has a positioning function and increases the contact area between the grinding layer 300 and the saw body 100, thereby improving the installation accuracy and stability between the two. Specifically, the cross-sectional shape of the groove is a rectangular structure, that is, the side wall and the bottom wall of the groove are arranged vertically.
[0034] In the embodiment of the utility model, Figure 1As shown, the grinding layer 300 is symmetrically arranged on both sides of the saw body 100. The grinding layer 300 is a truncated cone structure, with its large end fixed to the end surface of the saw body 100 and its small end protruding from the end surface of the saw body 100. The grinding layer 300 is arranged coaxially with the saw body 100. In this arrangement, the thickness of the grinding layer 300 gradually increases from the outer peripheral side to the middle area, so that the overall structure of the saw blade is thick in the middle and thin at the edges, thereby ensuring the running stability of the saw blade.
[0035] Specifically, the lower end of the grinding layer 300 has a circumferential surface adapted to the groove in the middle area of the saw body 100 , and the thickness of the circumferential surface is the same as the depth of the groove, that is, the upper edge of the circumferential surface is flush with the end face of the saw body 100 .
[0036] In the embodiment of the utility model, the center of the saw body 100 has a first mounting hole 110, and the center of the grinding layer 300 has a second mounting hole 310. The second mounting hole 310 is adapted to the first mounting hole 110 and is used for fixed installation on the sawing shaft. For example, it can be fixedly installed by fasteners such as bolts and nuts. Specifically, the first mounting hole 110 and the second mounting hole 310 have the same diameter and are arranged opposite to each other.
[0037] In the embodiment of the utility model, the grinding layer 300 is detachably fixed to the saw body 100, such as by welding, connection through fasteners, clamping, interference fit formed by mechanical extrusion, etc. The specific connection method is not limited here.
[0038] In the embodiment of the utility model, there is an adjustment structure (not shown in the figure) between the grinding layer 300 and the saw body 100 to adjust the axial relative position of the grinding layer 300 relative to the saw body 100. The adjustment structure can be an adjustment structure in the prior art, and no limitation is made to this. With such a configuration, when the grinding layer 300 is ground and thinned, the relative position between it and the saw teeth 200 can be adjusted by adjusting the relative position.
[0039] Specifically, in the embodiment of the utility model, the grinding layer 300 is a grinding wheel, which is a special-shaped grinding wheel with a frustum structure. After being installed on the saw body 100, they form a structure with a thick middle and thin edges.
[0040] In the embodiment of the utility model, the saw tooth 200 and the saw body 100 are integrally arranged. In addition, the two can also be connected in other ways, such as welding, or the saw tooth 200 and the saw body 100 are detachably fixedly connected, such as snap-fitting, interference fit formed by mechanical extrusion, etc. The specific connection method is not limited here.
[0041] In the embodiment of the utility model, the size of the saw blade is not limited, for example, it can be: the saw blade diameter is 405mm, the number of teeth of the saw tooth 200 is 128, the thickness of the saw tooth 200 is 3.2mm, the width (radial) of the saw tooth 200 is 2.6mm, the outer thickness of the saw body 100 is 2.8mm, the thickness of the central area of the saw body 100 (between the bottom of the two grooves) is 2.2mm, the saw body 100 and the grinding layer 300 share a mounting hole, and the diameter of the mounting hole is 30mm; the thickness of the thin outer side of the grinding layer 300 is 0.6mm, and the thickness close to the shared mounting hole is 2.5mm; the width (radial) of the central area of the saw body 100 is 10mm.
[0042] When the saw blade provided by the embodiment of the utility model is used, after the saw body 100 and the grinding wheel (grinding layer 300) are assembled, they are fixedly installed on the sawing shaft. Since the thickness of the saw body 100 is less than the thickness of the saw teeth, when sawing, the saw teeth first contact the profile and cut the profile into a saw cut. The saw continues to move forward, and the saw body 100 does not contact the profile. The saw continues to move forward. The thin parts around the upper and lower special-shaped grinding wheels do not contact the profile. The saw continues to move forward. When the sum of the thickness of the upper and lower special-shaped grinding wheels and the thickness of the center saw body is greater than the thickness of the saw teeth, the grinding wheel contacts the profile and grinds the end face of the profile. At this time, the special-shaped grinding wheel will grind the end of the aluminum profile to achieve the purpose of deburring.
