Abstract
The utility model discloses a kind of diamond disc saw blades, including saw bit matrix, the saw bit matrix includes centre bore and cutting edge, the cutting edge circumferentially offers several arc grooves, the side radian of this arc groove is higher than its other side radian, in irregular wave shape wave, and the size for being located at the arc groove of circular saw bit four directions position is much larger than the arc groove size of other positions, serve as chip space, the cutting edge is outer and arc groove, the intrados of chip space is coated with diamond, the centre bore is externally provided with terminal pad block, the terminal pad block is connect by several heat sink strips with saw bit matrix, there are heat-dissipating spaces between the terminal pad block and saw bit matrix.A kind of diamond disc saw blade provided by the utility model can realize the service life for increasing diamond disc saw blade very well.
Description
Technical field
The utility model relates to a kind of circular saw bit, especially a kind of diamond disc saw blade.
Background technique
No explosion cutting main construction techniques: circular sawing machine (vertically separated) → rope saw (horizontal separation) → hydraulic vertical
Straight brill and hydraulic splitting machine (quarry stone decomposition) → digging machine, fork truck, dumper (stone transport).
The diamond saw blade that circular sawing machine uses covers one layer of diamond coatings in saw sword and cutting edge surface, when in use,
Diamond coatings just not can guarantee sharpness after being worn, service life is short.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of diamond disc saw blade.
The technical solution of the utility model are as follows: a kind of diamond disc saw blade, including saw bit matrix, the saw bit matrix packet
Centre bore and cutting edge are included, the cutting edge circumferentially offers several arc grooves, and the side radian of this arc groove is higher than
Its other side radian is in irregular wave shape wave, and the size for being located at the arc groove of circular saw bit four directions position is much larger than other
The arc groove size of position serves as chip space, and the cutting edge is outside and the intrados of arc groove, chip space is coated with gold
Hard rock, the centre bore are externally provided with terminal pad block, and the terminal pad block is connect by several heat sink strips with saw bit matrix, described
There are heat-dissipating spaces between terminal pad block and saw bit matrix.
Preferably, the chip space is centrosymmetric arrangement on the saw bit matrix relative to the saw bit matrix center of circle.
Preferably, the heat sink strip is arranged along terminal pad block week radiotropism.
Compared with prior art, the utility model has the following beneficial effects: a kind of diamond provided by the utility model
The diamond of circular saw bit, cutting edge is first worn, after Diamond Wear, the diamond of arc groove, chip space inner face
Continue to use as cutting edge, relative to normal diamond, its service life increases significantly；Meanwhile chip space can be used as chip removal and make
With；Last terminal pad block not only contributes to the axis connection of circular saw bit, and connection mounting opening also facilitates, its heat of axis body adstante febre
Also it can be dissipated in heat-dissipating space, further extend service life.
Detailed description of the invention
Fig. 1 is the vertical view figure structure schematic representation of the utility model.
Fig. 2 is the front sectional view of the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1 to Figure 2, a kind of diamond disc saw blade, including saw bit matrix 1, saw bit matrix 1 include centre bore 2
With cutting edge 3, cutting edge 3 is circumferential to offer several arc grooves 4, and the side radian of this arc groove 4 is higher than its other side
Radian (being in irregular wave shape wave), and the size for being located at the arc groove of the cubic position of saw bit matrix 1 is much larger than other positions
Arc groove size, serves as chip space 5, and chip space 5 is centrosymmetric arrangement on saw bit matrix 1 relative to the saw bit matrix center of circle.
Outside cutting edge 3 and the intrados of arc groove 4, chip space 5 is coated with diamond.
Centre bore 2 is externally provided with terminal pad block 7, and there are heat-dissipating spaces between terminal pad block 7 and saw bit matrix 1；Terminal pad block 7
It is connect by several heat sink strips 6 with saw bit matrix 1, several heat sink strips 6 are arranged along 7 weeks radiotropisms of terminal pad block.
The above embodiments are only the preferred embodiment of the utility model, and the right of the utility model cannot be limited with this
Range, therefore, modification made according to the patent scope of the utility model, equivalent variations, improvement etc. still belong to the utility model institute
The range covered.
