Description

A kind of cutter of processing graphite thermal field device

[technical field]

The utility model relates to manufacture field, especially relates to a kind of cutter that is used for processing graphite thermal field device.

[background technology]

At present; Along with the extensive use of monocrystalline silicon at industry-by-industry; Particularly human development and use to solar energy cause the demand of graphite thermal field to continue to increase, and the core component in the graphite thermal field mainly contain heater, graphite crucible, heat-preservation cylinder, interior external flow guiding cylinder etc.; Because this material of graphite is not only crisp but also hard; Therefore a lot of enterprises produce graphite device spare according to the processing technology of processing metal spare; But so; Cutting graphite raw material down just can only be regarded leftover bits and pieces and disposed in process, and promptly these cut the graphite raw material that gets off owing to can not moulding, so can only have been wasted; At present; Though the existing cutter that can when the processing heater, draw out complete graphite core avoids in process, producing particle; But owing to still there is suitable cutter not processed once more by graphite cores of being drawn out, it is made as other devices in the graphite thermal field to these, like volume less than the graphite crucible of heater or interior external flow guiding cylinder etc.; Therefore, processing graphite thermal field device is to a certain degree existing the bigger phenomenon that wastes raw material present stage.

[summary of the invention]

In order to overcome the deficiency in the background technology; The utility model provides a kind of cutter of processing graphite thermal field device; Described cutter can be processed the graphite core that processing is drawn out during heater once more; Thereby effectively raise the utilization rate of raw materials for production, for manufacturing enterprise has saved production cost.

For realizing the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of cutter of processing graphite thermal field device, described cutter comprises handle of a knife, knife bar and cutter head; Described handle of a knife is longer than knife bar, and the end face of handle of a knife one end is made as the inclined-plane; Described knife bar shaft one end is fixedly connected with the inclined-plane of handle of a knife, and knife bar after the fixed connection and the angle between the handle of a knife are 105 degree; The other end of knife bar shaft is provided with cutter head, and the parallel axes of the knife edge of cutter head and handle of a knife.

The cutter of described processing graphite thermal field device, described handle of a knife and knife bar are made as integrative-structure.

The cutter of described processing graphite thermal field device, described knife bar and cutter head are made as integrative-structure.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The cutter of the described processing graphite thermal field of the utility model device can be processed the graphite core that processing is drawn out during heater once more; And graphite core is processed into other devices in the graphite thermal fields such as graphite crucible or interior external flow guiding cylinder; Thereby effectively in the link of processing graphite thermal field device, improved the utilization rate of raw materials for production, for manufacturing enterprise has saved production cost.

Among the figure: 1, handle of a knife; 2, knife bar; 3, cutter head.

[specific embodiment]

Can explain the present invention in more detail through following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope, and the utility model is not limited to following embodiment;

In conjunction with the cutter of accompanying drawing 1 described processing graphite thermal field device, described cutter comprises handle of a knife 1, knife bar 2 and cutter head 3; Described handle of a knife 1 is longer than knife bar 2; And the end face of handle of a knife 1 one ends is made as the inclined-plane; An end of being convenient to knife bar 2 shafts is fixedly connected with handle of a knife 1 through the inclined-plane of handle of a knife 1; And make knife bar 2 and the angle between the handle of a knife 1 after the fixed connection be 105 degree, thereby the graphite core of drawing out when utilizing this angle to the processing heater draw accordingly and dig, reach when not damaging graphite core and draw the purpose of digging out graphite crucible or interior external flow guiding cylinder through cutter head 3; For ease of making described cutter, can described handle of a knife 1 be made as integrative-structure with knife bar 2; The other end of said knife bar 2 shafts is provided with cutter head 3, and the parallel axes of the knife edge of cutter head 3 and handle of a knife 1, and when promptly utilizing described cutter to process corresponding graphite core, the knife edge of cutter head 3 can not hindered because of the action of handle of a knife 1 when digging graphite core drawing; Add the dynamics of digging of drawing in man-hour for strengthening cutter head 3, can described knife bar 2 be made as integrative-structure with cutter head 3.

Implement the cutter of the described processing graphite thermal field of the utility model device; The graphite core of drawing out in the time of will processing heater earlier passes through computer Simulation; Calculate the graphite crucible that to process or the size or the angle of interior external flow guiding cylinder; Select the cutter of appropriate size then; And the cutter handle of a knife of selecting is fixed on the compound tool rest, according to the angle of the internal diameter size of graphite crucible or interior external flow guiding cylinder cutter being adjusted to behind the suitable position graphite core drawn again and digging processing, the blank of crucible or interior external flow guiding cylinder is drawn out the most at last; In addition; According to graphite core and graphite crucible to be processed and in the concrete condition of external flow guiding cylinder; Utilize described cutter to add man-hour, can also process the blank of a graphite crucible earlier, and then the blank of external flow guiding cylinder in remaining graphite core, processing; Thereby effectively utilized graphite core, for manufacturing enterprise has saved production cost.

Carefully not stating in the above content is prior art partly, does not state so run business into particular one.
