Abstract
The utility model discloses a special alloy saw blade for cutting aluminium materials. The special alloy saw blade comprises a saw blade base body and an alloy cutter head; the alloy cutter head is fixed at the periphery of the saw blade base body; the thickness of the saw blade base body is 1.5-5 mm; the thickness of the alloy cutter head is 1.8-6 mm; silencing grooves and expansion grooves are formed on the saw blade base body at intervals; mounting holes are formed at the periphery of a central hole in the middle of the saw blade base body; the alloy cutter head is formed by trapezoidal teeth and flat teeth which are mutually crossed; the trapezoidal teeth are higher than the flat teeth by 0.1-0.5 mm; and the side surfaces of the trapezoidal teeth and the flat teeth adopt are inclined surfaces, and the inclination angle of the inclined surface is 1 DEG. When the special alloy saw blade is used for cutting the aluminium materials, the influence on the cutter head caused by the vibration is effectively reduced, the possibility that the teeth of the cutter head are broken is prevented, the service life of the cutter head is prolonged, the finish degree of the sawn joint is improved while the cutting efficiency is ensured, the deformation caused by the heat produced when the saw blade cuts is eliminated, and the cutter head adjacent to the expansion grooves is protected.
Description
Technical field
The utility model relates to a kind of cutting special metals saw blade, is widely used in the cutting of hard wood, softer metals, is particularly useful for the cutting of aluminium.
Background technology
Along with the development of society, the raising of productivity when people improve the cutting tool quality requirement, is also had higher requirement to the cutting processing precision, and the noise requirements during particularly to the loss of cutting life-span, material and cutting is significantly improved.The primary structure of alloy saw blade is to have to be welded on saw bit matrix alloy cutter head on every side, when cutting object is hard wood, soft metal, have significantly different to the requirement and the cutting common wood of adhesion, tip size, pattern and matrix between alloy cutter head and the matrix.
The open defect of existing aluminium cutting special metals saw blade is: 1, cutting accuracy is low, and slot is crude; 2, the adhesion between alloy cutter head and the matrix is lower, collapses tooth easily; 3, the discharge of aluminium bits is not smooth, is bonded at easily on the cutter head, influences cutting accuracy and saw life; Saw blade serious vibration when 4, cutting, noise is bigger, and environment is had bigger noise pollution.
Summary of the invention
The purpose of this utility model is for overcoming the defective of above-mentioned prior art, a kind of aluminium cutting special metals saw blade is provided, the fineness at alloy saw blade slot place is increased substantially, and can reduce the vibration of alloy saw blade and the noise in when cutting, the bulk strength and the service life of improving saw blade simultaneously.
The technical solution adopted in the utility model is: be made up of saw bit matrix and alloy cutter head, saw bit matrix circumferentially is fixed with alloy cutter head, and the thickness of saw bit matrix is 1.5～5mm, and the thickness of alloy cutter head is 1.8～6.0mm; Be provided with noise reduction groove and expansion slot on saw bit matrix, noise reduction groove and expansion slot are spaced apart; Around the centre bore in the middle of the saw bit matrix, be provided with installing hole; Described alloy cutter head is made up of stepped tooth and the mutual cross arrangement of flat tooth, and stepped tooth is 0.1～0.5mm than flat tooth depth and difference in height h; It is 1 ° inclined-plane that the side of stepped tooth and flat tooth is the inclination angle.
The beneficial effects of the utility model are:
1, adopts silver-bearing copper component alloy weld tabs welding alloy cutter head, can effectively reduce the influence of vibration during cutting, reduced the possibility that cutter head collapses tooth, prolonged the life-span of cutter head cutter head.
2, adopt stepped tooth and flat tooth cross arrangement, and the flat tooth height of stepped tooth aspect ratio is big, stepped tooth plays cutting action, and flat tooth works to revise, optimize saw kerf, has improved the fineness of saw kerf like this when guaranteeing cutting efficiency greatly.
3, have the noise reduction groove on the saw bit matrix, the noise pollution when having reduced the saw blade cutting, the vibration that has alleviated saw blade has simultaneously improved the integral rigidity of saw blade.Expansion slot effect on the saw bit matrix is: saw blade can produce a large amount of heats when cutting; therefore saw bit matrix can expand, and makes saw blade that small deformation take place, because the existence of expansion slot; the cutter head adjacent with expansion slot also protected in the distortion that heating causes when having eliminated saw blade because of cutting simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model front view.
Fig. 2 is the enlarged drawing of local A among Fig. 1.
Among the figure: 1. noise reduction groove; 2. expansion slot; 3. centre bore; 4. installing hole; 5. saw bit matrix; 6. alloy cutter head; 7. stepped tooth; 8. flat tooth.
The specific embodiment
As Fig. 1, aluminium cutting special metals saw blade is made up of saw bit matrix 5 and alloy cutter head 6, saw bit matrix 5 circumferentially be fixed with alloy cutter head 6, alloy cutter head 6 is by silver-colored and copper component alloy weld tabs, and, require smooth welded seam even along circumferentially being fixedly welded on the saw bit matrix 5 of saw bit matrix 5.The thickness range of saw bit matrix 5 is 1.5mm～5mm, and the thickness range of alloy cutter head 6 is 1.8mm～6.0mm.If when cutting object was the bigger aluminium of aluminium bar equal thickness, saw bit matrix 5 thickness were 1.8～5mm, alloy cutter head 6 thickness are 2.0～6.0mm.Be provided with noise reduction groove 1 and expansion slot 2 on saw bit matrix 5, noise reduction groove 1 and expansion slot 2 are spaced apart.Around the centre bore in the middle of the saw bit matrix 53, have installing hole 4.Do the stress processing again after on saw bit matrix 5, holding the noise reduction groove successfully, resist saw blade stress and strain owing to stressed generation when cutting.
As Fig. 2, alloy cutter head 6 is made up of stepped tooth 7 and flat tooth 8 mutual cross arrangement, and stepped tooth 7 is than flat tooth 8 height, and stepped tooth 7 is 0.1mm～0.5mm with the difference in height h of flat tooth 8, and cutting object thickness is big more, and the h value is big more.Stepped tooth 7 is the inclined-plane that has certain gradient with the side of flat tooth 8, and inclination angle C is 1 °, and purpose is to make alloy cutter head 6 bring into play dissection the biglyyest.
