Description

A kind of compound silencing circular saw disc

Technical field

The utility model discloses a kind of compound silencing circular saw discs, belong to cutting mechanics field, and in particular to a kind of compound Silencing circular saw disc.

Background technology

Saw blade will produce larger noise pollution in sawing process, larger to the harm of environment and human body, therefore circle The noise reduction problem of saw blade, causes the enough attention of people already；But intensity is universal under traditional sandwich saw blades stack pile Decline.So not influencing cutting efficiency, under the premise of the basis for cutting stability and other performances, in common noise reduction On the basis of saw blade, a kind of Novel saw blade that can control and reduce well noise pollution of making.

The structure of traditional sandwich saw blades, which is generally in two layers of saw blade, is mingled with one layer of noise reduction layer, is offset and is sawed by noise reduction layer The quieter material of the vibration of piece ontology, middle layer is combined into stacking knot using metal materials such as aluminium foil, copper foils by welding manner Structure.There is the silent saw blade matrix middle layer of particular type to use nonmetallic materials, for example, plastics, rubber, fiber etc., by viscous It closes or spot welding mode combines.The mode for taking joint-cutting filling clay also makes saw blade eliminate larger make an uproar in cutting process Sound reduces noise, etc. using noise elimination slot structure.But the measure of these current reduction noises, is all by saw blade base Body is overlapped.

Utility model content

Based on the above issues, the utility model provides a kind of unconventional silent saw blade matrix.

The utility model is made of following scheme：

A kind of compound silencing circular saw disc, including：Two clamping plates, two copper foils and a saw bit matrix, described two Clamping plate is symmetrically distributed in the both sides of saw bit matrix, and described two clamping plates etc. are big, and two copper foils are symmetrically fixed on clamping plate Between saw bit matrix；The saw bit matrix is in the form of annular discs and with centre bore, and the copper foil and disk etc. are big, and described two A clamping plate carries centre bore, and described two clamping plate radiuses are less than the difference of saw bit matrix radius and depth of cut.

Further, the saw bit matrix edge is processed into corresponding sawtooth and solderable cutter head.

Further, the saw bit matrix section diameter is 200mm-600mm, thickness >=1mm, the plane of the matrix Degree is less than 0.15mm.

Further, mounting hole and location hole can be carried on the saw bit matrix.

Further, the connection type between the copper foil and saw bit matrix, between clamping plate and copper foil and saw bit matrix For welding.Further, the distance in the location hole distance center hole is more than the radius of clamping plate, the mounting hole and positioning The shape in hole can be round, rectangular, linear or curved shape.

Further, the clamping plate material is the materials such as 75Cr1,65Mn, 30CrMo, and two clamping plates are material of the same race, It can spot-welded height, medium carbon steel.

The utility model has the advantage of：

1) the utility model changes the structure of traditional sandwich silent saw blade, and the copper foil for absorbing vibrations is welded on saw The both sides of sheet matrix, and the clamping plate of unlike material is set, higher support strength is provided for saw bit matrix, effectively can reduce or disappear Except saw blade internal stress, its intensity can be improved, or under the premise of ensureing its intensity in the case of equivalent weight, saved former The dosage of material；More efficient action can be performed quickly when high speed rotation is cut, it is not necessary to excessive worry tradition sandwich structure The strength reduction brought causes saw blade when high-speed cutting to be damaged.

2) the utility model uses the material of the absorption vibrations based on copper foil, utilizes the different physical properties of copper and saw blade Slow down the vibrations that saw bit matrix is generated in high-speed cutting, since copper foil is welded on the two sides of saw blade, actually two layers The cushioning ability of copper foil is above traditional sandwich structure saw blade.

3) the utility model is also provided with the clamping plate with saw bit matrix unlike material, is equivalent in saw bit matrix and copper foil Outer layer is superimposed one layer of silencing apparatus again, and the two is its intrinsic vibration frequency when vibrating using made of different materials Difference, therefore generation resonance is avoided, to further reduced noise.
