Abstract
The utility model relates to a saw blade type milling cutter which comprises a cutter head and a plurality of cutter blades, wherein a plurality of tooth parts and positioning convex parts are formed at the periphery of the cutter head in a staggered manner at intervals, and the cutter blades are respectively clamped between each tooth part and each positioning convex part of the cutter head. Due to the design, when the cutting edge of one cutter blade is broken and damaged, all that is needed is to demount the damaged cutter blade for replacement, and the entire saw blade milling cutter is not required to be discarded due to the damage of one cutter blade, thereby achieving the purpose of efficiently saving the material cost.
Description
Technical field
The utility model is about a kind of saw blade type milling cutter, especially refers to a kind ofly be provided with some removable blades in a cutterhead, so that the saw blade type milling cutter that can change individually during breaks down.
Background technology
Saw blade type milling cutter is a kind of dish-type that roughly is, and is provided with the cutter of plural blade in the periphery spacer ring.This kind saw blade type milling cutter is arranged on the toolroom machine in use, the driving of mat toolroom machine and at a high speed rotation, and then in order to metal materials such as cutting copper coin, aluminium sheets, or in order to cut wood, also can be in order to the plastic sheet of cutting as circuit board and so on.Under the design of precision and distance were adjusted, this saw blade type milling cutter also can process shallow slot on slim sheet material, so that after this sheet material machines, can fracture and disassembled and be a plurality of sub-sheets along this shallow slot.
Referring to the saw blade type milling cutter 30 of a prior art shown in Figure 5, it includes a cutterhead 31 and a plurality of blade 32: cutterhead 31 generally is made with the high-speed steel material, on its periphery at interval radially projection plurality of pins portion 311 is arranged; Blade 32 is a block, generally is made with hard artificial diamond or wolfram steel material, and is fixed in respectively with welding manner in each tooth portion 311 of cutterhead 31, and wherein the section of the end of each blade 32 is reverse V-shaped and forms a sharp-pointed blade 321.
Above-mentioned 32 on cutterhead 31 and blade are not made after affixed design mutually again, main purpose is to wish to use costliness but hard artificial diamond or wolfram steel gets final product in cutting place of key, and is too high with the cost of avoiding whole saw blade type milling cutter.
Yet, although the general material of the hardness of artificial diamond and wolfram steel is high, but after using a period of time, the blade 321 of blade 32 still can produce cracked, but because of blade 32 is fixed on the cutterhead 31 with welding manner, even therefore have only the blade 321 of one of them blade 32 to damage, and the blade 321 of other blades 32 is still intact, but the blade 32 for fear of this damage destroys sheet material to be processed, still must change whole saw blade type milling cutter, so will cause the waste of material, especially artificial diamond costs an arm and a leg, more can cause pecuniary loss, so the saw blade type milling cutter of prior art still has it to treat further improvements.
The utility model content
In view of aforementioned the deficiencies in the prior art, the utility model provides a kind of saw blade type milling cutter, wish that the blade of the saw blade type milling cutter of design solution prior art is fixed on the cutterhead with welding manner by this, thereby the shortcoming that can't only change at the blade of one damage.
In order to reach above-mentioned creation purpose, the technological means that the utility model utilized has a saw blade type milling cutter:
One cutterhead, its periphery at interval radially projection plurality of pins portion is arranged, between the two adjacent teeth portion radially projection one location protuberance is arranged;
A plurality of blades, it is an elongated block respectively, and an end of each blade is a cutting part, and the other end is a joint portion, and the section of this cutting portion is reverse V-shaped and forms a sharp-pointed blade, and this joint portion is fastened between the tooth portion and positioning convex portion of cutterhead.
Advantage of the present utility model is, this blade is located on the cutterhead in the fixing mode, therefore when the blade fracture damage of a blade wherein, as long as the blade that will damage can be changed by unloading on the cutterhead, need not be only because of a breaks down wherein just abandons whole saw blade type milling cutter, can effectively reach the purpose of saving material cost.

The specific embodiment
Referring to shown in Figure 1, saw blade type milling cutter of the present utility model includes a cutterhead 10 and a plurality of blade 20, wherein:
Cooperation is referring to shown in Figure 2, cutterhead 10 is one to be round flat plate body, on its periphery at interval radially projection plurality of pins portion 11 is arranged, between the two adjacent teeth portion 11 radially projection have one the location protuberance 12, make the adjacent and corresponding wherein side of this tooth portion 11 and positioning convex portion 12 be respectively a locating surface 111,121, further referring to shown in Fig. 3 and 4, this locating surface 111,121 are a convex surface respectively, wherein, angle theta between free-ended cutterhead 10 circumferential surfaces of the locating surface 111 of this tooth portion 11 and tooth portion 11 is an acute angle, and the locating surface 111 that makes this tooth portion 11 is an inclined-plane, and further indent is formed with a caulking groove 112 on the locating surface 111 of this tooth portion 11;
Cooperation is referring to shown in Figure 3, when the joint portion 22 of this blade 20 is arranged between the tooth portion 11 of cutterhead 10 and the positioning convex portion 12, mainly be that the fixing face 221 and the locating surface 111,121 of concavo-convex cooperation between the mat three is positioned blade 20 packings between this tooth portion 11 and the positioning convex portion 12; In addition, more the joint portion 22 of mat blade 20 is arranged in the caulking groove 112 of tooth portion 11 of cutterhead 10 and is resisted against on the wall of this caulking groove 112, and the limited block 23 of blade 20 fastens in the end of the positioning convex portion 12 of cutterhead 10, makes this blade 20 can be positioned specific location on the cutterhead 10; Again, this locating surface 111 that is the inclined-plane in the tooth portion 11 of cooperation cutterhead 10, when being arranged on the cutterhead 10, this blade 20 is oblique setting, that is its major axis bearing of trend can be by the axle center of cutterhead 10, design by this, can drive by a toolroom machine and during high speed rotating, this blade 20 firmly is combined on the cutterhead 10 at this cutterhead 10.
Aforesaid design, when a blade 20 damages therein, as long as this blade 20 of ejection, with it by unloading on the cutterhead 10, then just can a newer blade 20 of replacing be fastened on the cutterhead 10 and use, keeping the cutting effect of this saw blade type milling cutter, need not be only, a blade 20 wherein just whole metal saw be abandoned because of damaging, can effectively reach the purpose of saving material cost.
The above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model as described above discloses with preferred embodiment, yet be not in order to limit the utility model, any those of ordinary skill in the art, in the scope that does not break away from technical solutions of the utility model, should utilize the technology contents of above-mentioned announcement to make a little change or modification, become the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
