Fig. 2 is the top view of Fig. 1.
In above Fig. 1-Fig. 2:
The specific embodiment
In order further to understand the utility model, below in conjunction with embodiment, the utility model preferred embodiment is described, but should be appreciated that these describe just in order to further illustrate feature and advantage of the present utility model, rather than to the restriction of the utility model claim.
The utility model provides a kind of cutting knife, and it can cut out round and smooth circular port on the carbon felt, reduced cutting error.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the cutting knife that the utility model embodiment provides is used for incising circular hole on the carbon felt, and wherein, the blade of cutting knife surrounds blade part 1 cylindraceous.
In the cutting knife that the present embodiment provides, be set to blade part 1 cylindric, when the carbon felt is cut, put it on the surface at carbon felt position to be cut, then press down blade part 1, make each position of cylindric blade part 1 cut the carbon felt simultaneously, and then cut out the circular port identical with blade part 1 internal diameter on the carbon felt.
The cutting knife that the present embodiment provides, the mode that adopts 1 pair of carbon felt of cylindric blade part to cut, the mode that replaces original employing paper knife incising circular hole, make the cut surface that cuts the circular port that forms more round and smooth, reduced cutting error, make circular port can be better and the parts of single crystal growing furnace fit, reduce heat loss, and then make monocrystalline silicon to produce more smoothly.In addition, the cutting knife that adopts the present embodiment to provide cuts the faster and more convenient operation that makes the incising circular hole to the carbon felt, improved cutting efficiency.
In addition, the cutting knife that the present embodiment provides can be made a plurality of simultaneously, to adapt to the cutting demand of different-diameter circular port.
In order further to optimize technique scheme, in the cutting knife that the present embodiment provides, the lateral surface 2 of blade part 1 be taper seat, and the medial surface 3 of blade part 1 is the parallel arc surface of axis of the cylinder that surrounds with blade part 1, as shown in Figure 1.In the present embodiment, the lateral surface 2 of blade part 1 is set to taper seat, namely in order to form the less cutting edge of lifting surface area, the lateral surface 2 of blade part 1 is polished, make it form the inclined plane, and then the resistance when reducing to cut the carbon felt, its medial surface 3 is the parallel original arc surface structure of axis of the cylinder that surrounds of maintenance and blade part 1.In the process of reality, the difficulty that the medial surface 3 of cylindric blade part 1 is processed is larger, and the lateral surface 2 of blade part 1 is more convenient for processing the operation of polishing, so this kind set-up mode can be simplified process greatly.Certainly, under the prerequisite of not considering difficulty of processing, blade part 1 also can be set to medial surface 3 and be taper seat, lateral surface 2 is the structure of the parallel arc surface of the axis of the cylinder that surrounds with blade part 1, perhaps medial surface 3 and lateral surface 2 all are set to taper seat, and the incline direction of two taper seats is about former arc surface symmetrical structure.
Concrete, the blade section 4 of cutting knife is cylindric blade section, and its internal diameter equates with the internal diameter of blade part 1, as depicted in figs. 1 and 2.In the present embodiment, the processing and manufacturing of the cutting knife that the present embodiment provides namely is convenient in the cylindric blade section that preferably blade section 4 is set to that internal diameter equates with the internal diameter of blade part 1, also can save material.Certainly, under the prerequisite that does not affect the cutting knife normal operation that the present embodiment provides, blade section 4 can also be other shape, and for example the cross section of its side is polygonal tubular blade section.
Further, the blade section 4 of cutting knife is provided with away from an end of blade part 1 boss 5 that protrudes blade section 4 sides, as depicted in figs. 1 and 2.The effect that boss 5 is set is to increase the lifting surface area that cutting knife bears the power source applied pressure, many power such as to bear and to extend service life of the cutting knife that the present embodiment provides, when employing is manually exerted pressure to cutting knife, this boss 5 can make cutting knife be subject to larger pressure and the more quick and easy carbon felt is cut, simultaneously also can be so that operating personnel use more comfortable.
Preferably, the blade section 4 of cutting knife and blade part 1 are respectively stainless steel blade section 4 and stainless steel blade part 1.Select stainless steel as the manufactured materials of blade section 4 and blade part 1, can reduce the corrosion that blade section 4 and blade part 1 are subject to, make the cutting knife that the present embodiment provides service life can be longer, maintenance cost be lower.In addition, in the situation that satisfy the cutting knife job requirement that the present embodiment provides, the manufactured materials of blade section 4 and blade part 1 can also be common steel alloy.
