Abstract
The utility model discloses a detachable hob cutter of granulator. The technical scheme has the main points that the cutter shaft is in the shape of a gear wheel, the gear wheel is provided with blades, the blades are connected with the cutter shaft through a fastener, and the cutting direction of the blades is consistent with the involute direction of the gear wheel. According to the detachable hob cutter of granulator, design of the cutting edge and the cutter shaft is improved, the machining process is simplified, change of the blades is facilitated, and the machining cost is reduced.
Description
Technical field
The utility model relates to the plastics machinery technical field, more particularly, relates to the detachable hobboing cutter of a kind of plastic grain cutting machine.
Background technology
The pelleter hobboing cutter need to be fit to the selection of the blade material chemical composition of the different demands of user, the different objects of cutting, needs the knife edge angular that is fit to, has both kept the sharp of blade, makes again blade have some strength and tipping in use not.It need to carry out good heat treatment process with the suitable hardness that reaches blade and very little internal stress, in use is unlikely to distortion.Cutter tooth is made along cylinder or circular cone the Gear Processing cutter tool ﹐ that helix arranges and is used for by generating processing circle post tooth wheel ﹑ worm gear and other cylindrical toothed workpiece (seeing that the tooth wheel adds work ﹑ gear).Be divided into Chi wheel Gun Dao ﹑ Wo wheel Gun Dao ﹑ non-involute generate hobboing cutter and single position hob etc. according to different ﹐ hobboing cutter of purposes.
at present, the pelleter hobboing cutter that occurs on market, blade and cutter shaft are Integral designs, the part of the cutting of blade, the blade cut part is higher than cutter shaft to the hardness requirement of strength of material, but because blade makes the material of both use identical with the design of cutter shaft one, this also will certainly increase processing cost, and the design of blade and cutter shaft one also can make processing cumbersome, any careless mistake and mistake have not been allowed in the process of hobboing cutter, otherwise whole hobboing cutter is scrapped, in use wherein the knife edge damage of some blades will be changed whole hobboing cutter, if the blade of keeping in mind originally damage keeps in repair the new blade of burn-oning, but the intensity not as original one-body molded blade, also can cause because welding incessantly makes the blade sliver of again burn-oning drop to and cut in the plastic rubber material of completing, also can cause the feeding augering screw of ejaculator by the blade scratch, lose more than gain on the contrary.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of pelleter detachable hobboing cutter, and the detachable hobboing cutter of this pelleter has improved the design of blade and cutter shaft, has simplified process, is convenient for changing blade, but also cuts down finished cost.
For achieving the above object; the utility model provides following technical scheme: the detachable hobboing cutter of pelleter; described cutter shaft be shaped as gear shape; described gear is provided with blade; described blade is connected by securing member with cutter shaft, and the cutting direction of described blade is consistent with the involute direction of gear.
By adopting technique scheme, blade separates design with cutter shaft, and this just can make the material of blade and cutter shaft not identical, has reduced the cost of processing, and has facilitated the processing of hobboing cutter.
Described blade is connected by securing member with cutter shaft, can when some breaks down wherein, just can change whole hobboing cutter so that blade is for convenience detach, only needs to change the blade that damages just passable.
The utility model further is set to: described blade is bar shaped, and described blade is fixed by bolt and gear.
The utility model further is set to: the end face of described cutter shaft is provided with locating hole, and described locating hole is symmetrical around the cutter shaft axis.
By adopting technique scheme, the cutter shaft end face is provided with locating hole, and locating hole has coordinated fixation with the projection in the pelleter rotating shaft.
Description of drawings
Fig. 1 is the structural representation of the utility model pelleter hobboing cutter embodiment;
Fig. 2 is the top view of the utility model pelleter hobboing cutter embodiment.
The specific embodiment
Referring to figs. 1 through Fig. 2, the detachable hobboing cutter embodiment of the utility model pelleter is described further.
The detachable hobboing cutter of a kind of pelleter; comprise cutter shaft 1; described cutter shaft 1 be shaped as gear shape; described gear is provided with blade 2; described blade 2 and cutter shaft 1 by bolt 3(it should be noted that herein described fastener can be also other securing member as pin, consider that blade 2 is to the convenience of dismounting, therefore the present embodiment is preferably; described securing member is bolt 3) connect, the cutting direction of described blade 2 is consistent with the involute direction of gear.By adopting technique scheme, blade 2 separates design with cutter shaft 1, and this just can make the material of blade 2 and cutter shaft 1 not identical, has reduced the cost of processing, and has facilitated the processing of hobboing cutter.Blade 2 is connected by securing member with cutter shaft 1, can when some blades 2 damages wherein, just can change whole hobboing cutter so that blade 2 is for convenience detach, only needs to change the blade 2 that damages just passable.
The utility model further is set to: the end face of described cutter shaft 1 is provided with locating hole 11, and described locating hole 11 is symmetrical (it should be noted that, the stability event locating hole 11 when considering the hobboing cutter rotation is symmetric) herein around cutter shaft 1 axis.
By adopting technique scheme, cutter shaft 1 end face is provided with locating hole 11, and locating hole 11 has coordinated fixation with the projection in the pelleter rotating shaft, thereby the rotation of pelleter rotating shaft drives the function that the rotation of hobboing cutter realizes cutting.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art, in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
