Abstract
Circular silica wool cutting means relates to a cutting means, especially a circular silica wool cutting means. Circular silica wool cutting means, its characterized in that the device comprises handle, body, solid fixed ring and the edge of a knife, and the body is cavity cylindrical pipe, and the handle symmetry is fixed on the pipe wall of body, and the body bottom sets up solid fixed ring, and the edge of a knife passes through the fixed screw and installs in solid fixed ring bottom. The utility model discloses a circular silica wool cutting means, the design science, simple structure, convenient to use has simplified the cotton manufacturing process that keeps warm, and the cotton overall dimension that keeps warm makes accurately, has improved the cotton preparation efficiency that keeps warm.
Description
Technical field
This utility model is related to a kind of cutting tool, especially a kind of circular quartz cotton cutting tool.
Background technology
Vgf(VGF) method is by the use of crucible as container, under low vacuum environment, by accurate temperature controlling,
By material, melt crystalline substance reuse a kind of method that VGF carries out crystal growth, vgf method due to growth monocrystalline when temperature
Degree gradient is relatively low, and growth rate is less, has become one of growth major diameter, the mainstream technology of low-dislocation-density crystal at present.
In vgf method, the making of heat-preservation cotton is the important component part for stove for the early stage, because vgf method grows germanium single crystal
It is a very long process, from intensification, material, the molten time planted, lower the temperature, cool down needs nearly two weeks.In the process, protect
Whether warm cotton meets size of burner hearth, whether uniformly insulation, whether Homogeneouslly-radiating, and the uniformity of whole thermal field grows to monocrystalline
Close important.Therefore, whether the standard that heat-preservation cotton makes directly affects the thermal field uniformity of crystal growth, is directly connected to germanium single crystal
The qualification rate of crystal during growth.
At present during making heat-preservation cotton, the heat-preservation cotton cutting method of employing is generally first with compasses or circular ferrum
Piece simple graph circle in heat-preservation cotton, then with blade or shears along arc track, heat-preservation cotton is cut into or is cut into requirement
Size, place into burner hearth use.But in manufacturing process, this method operation inconvenience, work efficiency are low, are difficult to be cut into
, when the heat-preservation cotton cutting puts into burner hearth, because heat-preservation cotton is uneven, easily seam between heat-preservation cotton and burner hearth in standard circular
Gap, thus have influence on crystal growth thermal field uniformity.
Content of the invention
To be solved in the utility model is exactly in current vgf germanium single crystal growth, and heat-preservation cotton makes inconvenience, makes not
Uniformly affect the problem of crystal growth thermal field uniformity, a kind of circular quartz cotton cutting tool is provided.
Circular quartz cotton cutting tool of the present utility model is it is characterised in that this device is by handle, body, retainer ring and knife
Mouth is constituted, and body is hollow cylindrical tubing, and symmetric handles are fixed on the tube wall of body, and body bottom arranges retainer ring,
The edge of a knife is arranged on retainer ring bottom by fixed screw.
Described handle is made up of two small cylindrical tube materials.
The described edge of a knife is annular.
Described body adopts cast iron quality, to increase deadweight, is easy to cut.
Circular quartz cotton cutting tool of the present utility model, design science, structure is simple, easy to use, simplifies insulation
The manufacturing process of cotton, heat-preservation cotton overall dimensions make accurately, improve the make efficiency of heat-preservation cotton.
Brief description
Fig. 1 is the front view of this utility model understructure；
Fig. 2 is the top view of this utility model understructure；
Fig. 3 is the axonometric chart of this utility model understructure.
Wherein, handle 1, body 2, the edge of a knife 3, retainer ring 4, fixed screw 5.
Specific embodiment
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1: circular quartz cotton cutting tool, it is made up of handle 1, body 2, retainer ring 4 and the edge of a knife 3, during body 2 is
Hollow-cylindrical tubing, is divided into internal diameter, external diameter, wall thickness, and size is pressed actual demand and designed, and body 2 adopts cast iron quality, to increase certainly
Weight, is easy to cut, handle 1 is made up of two small cylindrical tube materials, is symmetrically fixed on the tube wall of body 2, and body 2 bottom sets
Put retainer ring 4, the edge of a knife 3 is annular, big low height is pressed actual demand and designed, and the edge of a knife 3 is arranged on fixation by tightening fixed screw 5
Ring bottom.
Heat-preservation cotton is laid on the plank of one piece of horizontal positioned, both hands catch handle 1, the edge of a knife 3 is put by pull-up body 2
Heat-preservation cotton presses, heat-preservation cotton is cut through the edge of a knife 3, is changed into round pie, is pressed within body 2.With above method successively
The heat-preservation cotton of tiling presses, until body 2 is filled up by heat-preservation cotton cake, then takes out heat-preservation cotton, you can complete heat-preservation cotton
Make.
These are only a kind of embodiment of the present utility model, as long as employing structures described above, all should be fallen into this
The protection domain of utility model.
