Description
Technical field
This utility model relates to a kind of Anti-tarnishing frock, is specifically related to a kind of vacuum heat treatment furnace workpiece Anti-tarnishing work
Dress.
Background technology
Heat treatment production process of the prior art there are a lot of steel alloy, rustless steel, high temperature alloy etc. are required for using
Non-oxidation heat treatment, non-oxidation heat treatment includes atmosphere protection non-oxidation heat treatment and vacuum heat etc., and main purpose is to make
Obtain workpiece and realize heat treatment in the environment of atmosphere protection or vacuum, to obtain metallographic structure and the mechanical property that workpiece needs
Energy.Wherein vacuum heat because have does not aoxidizes, not decarburization, deforms little, degassing, surface of the work purification and the thermal efficiency
High free of contamination advantage is widely adopted.The cooling procedure of vacuum heat typically can use noble gas (such as argon and nitrogen)
Circulation temperature lowering, but in actual production owing to the degree of purity of cooling gas is not enough, in equipment life-time service stove not cleaning with
And cooling gas is directly by convection into the problems such as surface of the work so that workpiece asking of variable color occurs in the last rear surface of coming out of the stove that cools down
Topic.
In order to solve above-mentioned workpiece discoloration problem, a lot of heat treatment producers buy the higher noble gas of degree of purity, or
Often prepurging.These methods can alleviate surface of the work discoloration problem to a certain extent, but it is high, inefficient to there is cost
Problem.
Utility model content
The purpose of this utility model is to solve pure due to cooling gas of the cooling of vacuum heat in prior art
Cleanliness is not enough, equipment life-time service cleans not and cools down gas in causing stove and is directly by convection into the problem of surface of the work, makes
Obtain workpiece, in the last rear surface of coming out of the stove that cools down, variable color, and the noble gas of purchase high purity, or often prepurging one-tenth occur
This problem high, inefficient.And then provide a kind of vacuum heat treatment furnace the special frock preventing workpiece variable color.
The technical solution of the utility model is: a kind of vacuum heat treatment furnace workpiece Anti-tarnishing frock includes upper cover, barrel
With go to the bottom, go to the bottom and go to the bottom for step-like, barrel is cylindrical barrel, and barrel is welded on the step gone to the bottom, and upper cover lid is contained in cylinder
The contact surface of the port of wall, upper cover and barrel is taper seat, and taper seat is that A, A are in the range of 30 with the angle of the central shaft of barrel
To 45.
This utility model also includes disc cover plate, and the outside diameter of disc cover plate is than the little 1mm of interior circular diameter of barrel
To 2mm.
Going to the bottom and be made up of cylindrical first step and cylindrical second step, the diameter of cylindrical first step is than barrel
The little 0.5mm to 1mm of interior circular diameter, the diameter 5mm to 8mm bigger than the outside diameter of barrel of cylindrical second step.
This utility model also include upper cover handle and cover plate handle, upper cover handle and cover plate handle be respectively welded at upper cover and
On the upper surface of cylindrical cover.
The surface roughness of the contact surface of upper cover and barrel is Ra1.6.
Upper cover handle, cover plate handle, upper cover, barrel, cover plate and all employing heat resisting steel of going to the bottom are made.
This utility model compared with prior art has the effect that
1, during operation, workpiece 7 is placed in barrel, it is to avoid workpiece 7 directly contacts with stove, only need to be to this utility model
Being carried out, this utility model simple in construction, cylindrical barrel is easy to cleaning, without dead angle.This technical scheme can have
Effect ground solves the cooling of vacuum heat in prior art, owing to cleaning not in equipment life-time service stove, makes workpiece the coldest
But come out of the stove the problem that variable color occurs in rear surface.
2, when carrying out vacuum heat, owing to processed workpiece is placed in barrel, it is to avoid the direct convection current of cooling gas
To surface of the work, workpiece 7 is made to cool down, last, the problem that variable color occurs in rear surface of coming out of the stove.
3, the higher noble gas of degree of purity is bought, or often prepurging, it is possible to alleviate surface of the work to a certain extent
Discoloration problem, but cost is high, efficiency is low.And this utility model makes simple, easy to operate, and suppress surface of the work to become
The effect of color is notable, and frock can be reused, it is possible to is prevented effectively from the problems referred to above, and processing cost reduces 45%, due to nothing
Workpiece need to be discolored process, save operation, make working (machining) efficiency improve 60%.
4, upper cover of the present utility model is taper seat with the contact surface of barrel, and this taper seat with the angle of barrel central shaft is
30 to 45, the purpose of this design is during evacuation, and the air in frock is extracted out without obstruction, until
Vacuum reaches desired value.
5, cover plate outside diameter is than the little 1mm to 2mm of interior circular diameter of barrel, is equipped with the purpose of cover plate in this utility model
It is to realize the workpiece second protection when carrying out heat treatment.
