Description
[technical field]
The present invention relates to carbon packing ring manufacture craft, particularly relate to a kind of waste and old graphite karbate impervious graphite packing ring
Preparation method.
[background technology]
It is close that known carbon packing ring is that one is applied in the industries such as oil, chemical industry, generating to carry out machinery
A kind of seal that envelope uses, in sealed product manufacturing, graphite is the raw material of a kind of indispensability, profit
With widely, some industrial production of graphite application often produce the waste and old graphite of part, so-called useless
Old graphite, it is simply that the remaining tailing of industrial production, residue the part that cannot use such as chips, the past this
A little remainders can only abandon, and not only pollutes environment but also cause the substantial amounts of wasting of resources, has run counter to us and chased after
" energy-saving and emission-reduction, the low-carbon environment-friendly " theory asked；In sealed product manufacturing, graphite is a kind of indispensable
Raw material, utilize widely, in conventional production, remaining leftover pieces account for about 20-30%, this
It is quite surprising that kind is wasted in long-term production process, therefore, based on the utilization of the waste and old graphite of this part
Become a problem demanding prompt solution in the industry.
[content of the invention]
It is an object of the invention to effectively overcome the deficiency of above-mentioned technology, provide one to utilize waste and old graphite to make
The preparation method of the waste and old graphite karbate impervious graphite packing ring of carbon packing ring.
The technical scheme is that and be achieved in that: it comprises the following steps:
A, the selection mould supporting with product and hydraulic press, the tolerance of its mould should meet
The requirement of GB/T1804；
B, graphite waste is cleaned process, will be cleaned process after graphite waste be tailored into suitably
Graphite scrap；
C, being weighed the graphite block after tailoring by weighing utilities, its quality presses M=ρ ∏ (D2-d2)H/4
Calculate so that it is meet the requirement of JB/T6370-92 Midst density；
Wherein: ρ: the density of product during temperature t DEG C, unit is g/cm3；
The quality of M: product, unit is g；
The external diameter of D: product, unit is cm；
The internal diameter of d: product, unit is cm；
The average height of H: product, unit is cm；
D, will weigh after graphite scrap add hydraulic press；
E, the pressure of adjustment hydraulic press are to 0.3 to 0.4mpa, after maintaining 10 to 20s, in 10s at the uniform velocity
It is loaded onto 30mpa to 40mpa, maintain unloading after 55-65s, form carbon packing ring；
F, the surface to the carbon packing ring being formed in step D carry out fineness process, to reduce coefficient of friction,
Strengthen sensory effects.
Preferably, in described step D, the pressure of forcing press adjusts to 0.35mpa, after maintaining 15s, at 10s
It is inside at the uniform velocity loaded onto 35mpa, maintain unloading after 60s, form carbon packing ring.
Preferably, the weighing utilities using in described step C is the balance that sensibility reciprocal is 0.001g.
The beneficial effects of the present invention is: one, the present invention utilize waste and old graphite to make stone by hydraulic press
Ink packing ring, (about whole graphite cake of the tailing after the processing of monoblock graphite cake and residue can being chipped
20-30%) etc. be collected, then make carbon packing ring by the preparation method of the present invention, waste material entered
Row recycling, reduces enterprise's production cost, improves stock utilization, meets the theory of energy-conserving and environment-protective；
Two, product quality obtains corresponding raising, owing to waste and old graphite has re-started Combined machining after being pulverized,
The density making packing ring is more uniformly moderate, thus obtains more particularly suitable compression ratio, and can be random
Adjust so that it is meeting actual requirement, rebound degree is greatly improved, and have employed matched simultaneously
Process for treating surface, makes coefficient of friction obtain corresponding reduction, reaches better seal effect.
[detailed description of the invention]
Below in conjunction with embodiment, the invention will be further described.
What the present invention disclosed is the preparation method of a kind of waste and old graphite karbate impervious graphite packing ring, by this making side
Waste and old graphite can be carried out recycling and make carbon packing ring by method；It comprises the following steps:
A, the selection mould supporting with product and hydraulic press, the tolerance of its mould should meet
The requirement of GB/T1804, it is ensured that the tolerance of the carbon packing ring after shaping meets GB/T1804.
B, graphite waste is cleaned process, for example remove the removal of impurity, dust etc., will be cleaned process after
Graphite waste be tailored into suitable graphite scrap, it is simple to add hydraulic press；
C, being weighed the graphite block after tailoring by weighing utilities, its quality presses M=ρ ∏ (D2-d2)H/4
Calculate so that it is meet the requirement of JB/T6370-92 Midst density；
Wherein: ρ: the density of product during temperature t DEG C, unit is g/cm3；
The quality of M: product, unit is g；
The external diameter of D: product, unit is cm；
The internal diameter of d: product, unit is cm；
The average height of H: product, unit is cm；
In this weighing stage, according to the size requirements specifically producing carbon packing ring, calculate and produce required giving up
The quality of old graphite, so that the carbon packing ring of final molding meets wanting of JB/T6370-92 Midst density
Ask；Additionally, it is also preferred that the left the weighing utilities using in this step is the balance that sensibility reciprocal is 0.001g.
D, will weigh after graphite scrap add hydraulic press, utilize hydraulic press to suppress waste and old graphite；
E, the pressure of adjustment hydraulic press, to 0.35mpa, after maintaining 15s, are at the uniform velocity loaded onto 35mpa in 10s,
Maintain unloading after 60s, form carbon packing ring；
F, the surface to the carbon packing ring being formed in step D carry out fineness process, to reduce coefficient of friction,
Strengthen sensory effects.
The present invention utilizes waste and old graphite to make carbon packing ring by hydraulic press, can process monoblock graphite cake
After tailing and residue chip the 20-30% of graphite cake (about whole) etc. be collected, then pass through
The preparation method of the present invention makes carbon packing ring, carries out recycling to waste material, reduces enterprise and produces into
This, improve stock utilization, meet the theory of energy-conserving and environment-protective；Secondly, product quality obtains corresponding raising,
Owing to waste and old graphite has re-started Combined machining after being pulverized, the density making packing ring is more uniformly moderate,
Thus obtain more particularly suitable compression ratio, and can arbitrarily adjust so that it is meet actual requirement, resilience
Rate is greatly improved, and have employed matched process for treating surface simultaneously, makes coefficient of friction obtain
Corresponding reduction, reaches better seal effect.
Described above is only presently preferred embodiments of the present invention, and above-mentioned specific embodiment is not to the present invention
Limit.In the technological thought category of the present invention, various deformation and modification, all this areas general can occur
Retouching, modification or the equivalent that logical technical staff is made as described above, belongs to the present invention and is protected
