Embodiment
Further illustrate this practical technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in figure 1, a kind of hard alloy shell knife includes cutter hub 100, tool rest 200, cutting edge 110, tool rest 200 is used for
Cutter hub 100 is fixed, cutter hub 100 is circular shape, and cutting edge 110 is arranged at the one end of cutter hub 100 away from tool rest 200, cutting
Sword 110 includes the first blade 111, and is arranged on the second blade 112 of the both sides of the first blade 111, and the first blade 111 is located at knife
Body 100 is provided with the host cavity 113 for installing the first blade 111, the first knife in the distalmost end of tool rest 200, cutter hub 100
Mounting hole is provided with sword 111, and mounting hole is corresponded on the surface of cutter hub 100 and is provided with fixing hole, the first blade 111 is by setting
The bolt 212 being placed in mounting hole and fixing hole is fixed with cutter hub 100.
First blade 111 is located at cutter hub 100 apart from the distalmost end of tool rest 200, therefore during actual cut, the first knife
Sword 111 contacts with grit layer at first, and abrasion is very fast, and the degree of wear of the second blade 112 substantially reduces, and the first blade 111 wears
Cutting effect is influenceed, therefore the first blade 111 is designed to replaceable, avoids changing whole cutter hub 100, causes the wasting of resources,
The first blade 111 more renewed, so that shell knife can continue to use, improve cutting-tool's used life.By being arranged at installation
Bolt 212 in hole and fixing hole, the first blade 111 is fixed with cutter hub 100, using bolt 212 by the first blade 111 and knife
Body 100 is fixed, simple in construction, easy to process, and cost is low, can be realized and be dismantled the first blade 111 from cutter hub 100, and
By the convenient installation and removal speed that first blade 111 is arranged on cutter hub 100, improves the first blade 111, construction effect is improved
Rate.
For the ease of the replacing of the first blade 111, further, the quantity of first blade 111 and host cavity 113
It it is 3, and the first blade 111 is corresponded with host cavity 113 and set.Because shell knife is in working angles, away from tool rest
200 3 the first blades 111 contact sandstone at first, thus 3 the first blades 111 wear most fast, the abrasion of the second blade 112
Degree is relatively low, so design changes 3 the first blades 111 relatively appropriately, it is simple to operate, easily realize.
As shown in Fig. 2 for the ease of the cutting of the first blade 111, further, the free end of first blade 111
It is trapezoidal, by the free end design of the first blade 111 in echelon, it is easy to cut, improves stock-removing efficiency.
As shown in figure 3, being arranged on for the ease of the second blade 112 on cutter hub 100, further, set on the cutter hub 100
The groove 114 for installing second blade 112 is equipped with, the fixing end both sides of second blade 112 are provided with one wave part
112a, the side wall of the groove 114 are adapted with the shape of the one wave part 112a, are easy to the second blade 112 being fixed on recessed
In groove 114, the second blade 112 is set to be completely embedded with groove 114.
In order to reduce the abrasion to the first blade 111, further, first blade 111 and second blade 112
The periphery of equal spaced set cutter hub 100, when shell knife is cut, the cutting output of each blade is reduced so that the first blade 111
Suffered cutting force is accordingly reduced, and reduces the abrasion to the first blade 111 in working angles so that cutting-tool's used life increases
Add.
In order to realize the fixation of tool rest 200 and cutterhead 300, further, end has fixed part on the tool rest 200
210, it is provided with bolt hole 212 on the fixed part 210, the tool rest 200 passes through the bolt that is arranged in the bolt hole 212
It is connected with cutterhead 300, sets fixed part 210 tool rest 200 is contacted with cutterhead 300, by bolt 212 by fixed part 210 and knife
Disk 300 is fixed, and is easy to dismantle tool rest 200 from cutterhead 300, also allows for tool rest 200 being arranged on cutterhead 300.
In order to ensure tool rest 200 and the stable connection of cutterhead 300, further, the number of the bolt hole 211 is 6, respectively
Bolt is provided with bolt hole 211, fixed part 210 is disc-shape, and 6 bolts hole 211 are respectively provided with the same of fixed part 210
On one circular arc, and it is evenly distributed on fixed part 210, so that the contact surface uniform force of fixed part 210 and tool rest 200,
Make the uniform force of bolt 212, it is ensured that the stability of shell knife working angles.
Installed for the ease of the cooperation of tool rest 200 and cutterhead 300, further, the fixed part 210 is away from the tool rest
200 side is provided with the trapezoid boss 220 for guiding, sets trapezoid boss 220, is advantageous to being installed into tool rest 200
Row is oriented to, and is easy to assemble tool rest 200 on cutterhead 300.
This practicality is described with reference to the preferred embodiments, and those skilled in the art know, is not departing from this practicality
In the case of spirit and scope, various changes or equivalence replacement can be carried out to these features and embodiment.This practicality is not by this
The limitation of specific embodiment disclosed in place, other embodiments fallen into claims hereof belong to this practicality protection
Scope.
