Description
Technical field
The present invention relates to pipe fitting technical field of heat treatment technology, particularly a kind of pipe fitting quenching apparatus.
Background technology
Quenching is that steel is heated to critical-temperature Ac3 (sub-eutectoid steel) or Ac1 (hypereutectoid steel) temperatures above, is incubated one section
Time, it is allowed to all or part of austenitizing, then started with being as cold as martensite transfor mation soon more than the cooling rate of critical cooling rate
(or Ms nearby isothermal) below temperature Ms carries out the Technology for Heating Processing that martensite (or bainite) changes, include heating, be incubated, cold
But 3 stages；Quenching technical is widely used in modern mechanical manufacturing industry, machinery in strength member, especially automobile,
In aircraft, rocket, the steel part of application is nearly all through Quenching Treatment, and militarily, gun barrel, the pipe fitting such as gun tube is even more and be unable to do without
Quenching.
Steel high temperature phase austenite will be made in quenching to be transformed into low temperature metastable phase martensite in cooling procedure,
Cooling velocity have to be larger than the critical cooling rate of steel, and in cooling procedure, surface is had necessarily workpiece with the cooling velocity of center portion
Difference, if this species diversity is sufficiently large, is likely to result in and is partially converted to martensite more than critical cooling rate, and be less than critical
The center portion of cooling velocity can not be transformed into the situation of martensite, for ensureing that being all changed into martensite in whole cross section needs from cold
But the sufficiently strong hardening media of ability, to ensure that workpiece center portion has sufficiently high cooling velocity, reaches raising pipe fitting quenching degree, carries
High quenching hardness and make the uniform purpose of product hardness.
At present, in Publication No. CN202139274U Chinese patent application, disclose a kind of continuous pressurizing oil-injection quenching dress
Put；It by feeding device, roller-bottom type continuous furnace, take piece manipulator, oil injection quenching press, discharging manipulator, discharging transfer
Guipure, oil groove etc. are constituted；Heating furnace makes it meet quenching requirement for lamellar body is carried out with heating and thermal insulation；Piece manipulator is taken to be up to
The saw bit matrix that quenching requires is sent into and is carried out compacting oil spout quenching in oil injection quenching press, and hardening media delivers to Quenching press again
Recycle stream oil-recovery tank.Although the quenching unit in this patent is simple to operate, workpiece can continuously be suppressed with oil spout quenching,
But, because its oil spout quenching is quenching mode that is carrying out in oil holding slot and using pipeline system, to workpiece
Quenching velocity is limited, workpiece hardness can be led to little and hardness uneven it is impossible to effectively improve its quenching degree.
In the Chinese patent application of Publication No. CN103572035A, disclose a kind of process for quenching of annular work piece and
The quenching unit that the method is used；The process for quenching of described annular work piece includes following operation：By inner mold be arranged at
The operation of cooling down workpiece is carried out in the state of workpiece inner circumferential side after hardening heat heating；Reach less than 500 DEG C in workpiece temperature simultaneously
And before being reduced to martensite start temperature, if the inner peripheral surface of workpiece is contacted with inner mold and starts in bond, one
Side persistently carries out fettering and on one side presses workpiece with low pressure in the direction of the width and workpiece is inserted into the operation in outer mold；And
If after workpiece temperature reaches below martensite start temperature, by the direction of the width workpiece being pressed with high pressure, thus
Fetter workpiece in the direction of the width, and fetter the outer peripheral face of the workpiece of volumetric expansion because of martensitic traoformation using outer mold
Operation.
Although refer to the quenching to annular work piece in this patent, the main purpose of this patent is：In ring-type work
Before the outer peripheral face of part expands because of martensitic traoformation, insert it in outer mold, suppress outer peripheral face and the outer mold of workpiece
Contact and produce cut, reduce the allowance of the grinding of workpiece such that it is able to reduce the grinding step cycle, its core does not exist
In how quickly to be cooled down to ring-type or tubular workpiece, it is additionally, since its needs and assigns inner mold inside annular work piece, instead
And cooling velocity can be reduced, lead to workpiece hardness little and hardness uneven it is impossible to effectively improve its quenching degree.
In the Chinese patent application of Publication No. CN104232871A, disclose a kind of train wheel integral quenching new technology：
(1) first workpiece is loaded in lower vacuum heat-insulation die cavity and lower positioning die cavity, top die and upper vacuum heat-insulation die cavity decline with
Vacuum heat-insulation die cavity clamping workpiece simultaneously pressurizes；(2) the Integral quenching device rapid decrease of above-mentioned clamping workpiece and immerse quenching cold
But in medium, descend vibration on the whole, move horizontally, quenching medium jet flow stirs；(3), after cooling terminates, rise overally, on
Pressing mold is drawn off with upper vacuum heat-insulation die cavity lifting, workpiece.
But the type of cooling is the Integral quenching device rapid decrease of clamping workpiece and immerses quenching cooling Jie in this patent
In matter, descend vibration on the whole, move horizontally, the stirring of quenching medium jet flow is although quicker than usual manner, but quenching cooling
Medium overall flow difference can cause quenching degree, the problems such as hardness is uneven.
