Abstract
The utility model discloses an acetylene pulse vacuum carburization device. The acetylene pulse vacuum carburization device comprises a carburization furnace and an acetylene storage pot, wherein the acetylene pulse vacuum carburization device further comprises multiple cavities having the same shape and the same volume; each cavity is communicated with the acetylene storage pot; openings as many as the cavities are arranged on the upper surface and the lower surface of the carburization furnace at equal intervals; each cavity is correspondingly communicated with an upper surface opening and a lower surface opening; a first electromagnetic valve is arranged at the place where each opening locates; and each cavity and the acetylene storage pot are provided with a second electromagnetic valve. The acetylene pulse vacuum carburization device solves the problems that the oxidization of a crystal boundary is relatively serious due to gas carburization and a carburization layer inside a fine hole of a work-piece having the fine hole is not uniform enough in the prior art, can carburization on a work-piece with a relatively complex shape and on the inner part of the work-piece having the fine hole through an interval type acetylene carburization way, and also can obtain a relatively uniform carburization layer. The acetylene pulse vacuum carburization device, disclosed by the utility model, has the advantages of nearly no oxidization of the crystal boundary, good appearance of a finished product, low energy consumption, no environment pollution and a capability of guaranteeing high quality.
Description
Technical field
The utility model has related to a kind of acetylene pulse Vacuum cementing plant, belongs to the heat treatment technics field.
Background technology
Acetylene can obtain very high carbon potential, is a kind of carburizing agent very commonly used in the carburization process.Existing employing acetylene carries out that the process of carburizing normally carries out in air, because gas cementation causes grain boundary oxidation more serious, for the workpiece of pore, the cementation zone of pore inside is even not.
The utility model content
Technical problem to be solved in the utility model provides a kind of acetylene pulse Vacuum cementing plant, makes the cementation zone of the workpiece that utilizes this device to finish carburizing more even, does not have grain boundary oxidation to produce, and carburizing time is short, and energy consumption is little.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of acetylene pulse Vacuum cementing plant, comprise cementing furnace and acetylene storage tank, described a plurality of shapes, the cavity that capacity is identical of also comprising, each cavity is connected with described acetylene storage tank, the upper and lower surface of described cementing furnace all equidistantly is provided with the opening identical with described number of cavities, a corresponding upper surface open and the lower surface opening of being communicated with of each cavity, described each opening part is provided with the first magnetic valve, and described cavity and acetylene storage tank are provided with the second magnetic valve.
Aforesaid acetylene pulse Vacuum cementing plant is characterized in that: also be connected with vacuum extractor on the described cementing furnace.
Aforesaid acetylene pulse Vacuum cementing plant is characterized in that: at least one described cavity pressure warning unit is installed.
Aforesaid acetylene pulse Vacuum cementing plant is characterized in that: the quantity of described cavity is 6.
The beneficial effects of the utility model are: the mode of the acetylene carburizing by interval type, can carry out carburizing to the comparatively complicated workpiece of shape, the inside workpiece of pore carries out carburizing, also can obtain more uniform cementation zone, and workpiece surface cleaning light, vacuum pulse carburizing infiltration rate is very fast, time is shorter, metallographic structure is even, and grain boundary oxidation is almost nil, the finished product outward appearance is good, power consumption less, non-environmental-pollution, again can guarantee high-quality.
Description of drawings
Fig. 1 is the structural representation of acetylene pulse Vacuum cementing plant of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of acetylene pulse Vacuum cementing plant, comprise cementing furnace 1 and acetylene storage tank 2, describedly also comprise a plurality of shapes, the cavity 3 that capacity is identical, each cavity 3 is connected with described acetylene storage tank 2, on the described cementing furnace 1, lower surface all equidistantly is provided with the opening identical with described cavity 3 quantity, each cavity 3 a corresponding upper surface open and lower surface opening of being communicated with, described each opening part is provided with the first magnetic valve 4, described cavity 3 is provided with the second magnetic valve 7 with acetylene storage tank 2, also be connected with vacuum extractor 5 on the described cementing furnace 1, at least one described cavity 3 pressure warning unit 8 be installed, the quantity of described cavity 3 is 6.
When utilizing this device to finish carburization process, close on the cementing furnace 1, the first magnetic valve 4 of lower surface opening part, open the second magnetic valve 7, by 2 pairs of cavitys of acetylene storage tank, the 3 interior acetylene gas that fill simultaneously, read pressure in the cavity 3 by pressure warning unit 8, when force value satisfies the pressure of carburizing needs, close the second magnetic valve 7, utilize vacuum extractor 5 to vacuumize in the cementing furnace 1, then open first magnetic valve 4 at cementing furnace 1 upper surface open place, acetylene gas is entered from cementing furnace 1 top, product 6 is carried out carburizing, behind the certain hour, close first magnetic valve 4 at cementing furnace 1 upper surface open place, utilize vacuum extractor 5 to vacuumize in the cementing furnace 1, open the second magnetic valve 7, by 2 pairs of cavitys of acetylene storage tank, the 3 interior acetylene gas that fill simultaneously, read pressure in the cavity 3 by pressure warning unit 8, when force value satisfies the pressure of carburizing needs, close the second magnetic valve 7, then open the first magnetic valve 4 of cementing furnace 1 lower surface opening part, acetylene gas is entered from cementing furnace 1 bottom, product 6 is carried out carburizing, behind the certain hour, close the first magnetic valve 4 of cementing furnace 1 lower surface opening part, utilize vacuum extractor 5 to vacuumize in the cementing furnace 1, the circulation said process is realized product 6 is carried out interval type vacuum carburization.
In sum, the acetylene pulse Vacuum cementing plant that the utility model provides makes the cementation zone of the workpiece that utilizes this device to finish carburizing more even, does not have grain boundary oxidation to produce, and carburizing time is short, and energy consumption is little.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
