Description
Technical field
The utility model is related to pipe fitting technical field of heat treatment technology, particularly a kind of pipe fitting quenching unit.
Background technology
Quenching is that steel is heated into critical-temperature Ac3 (sub-eutectoid steel) or Ac1 (hypereutectoid steel) temperatures above, is incubated one section
Time, all or part of austenitizing is allowed to, being then as cold as martensite transfor mation soon with the cooling rate more than critical cooling rate starts
Below temperature Ms (or Ms nearby isothermal) carries out the Technology for Heating Processing of martensite (or bainite) transformation, including heating, insulation, cold
But 3 stages；Quenching technical is widely used in modern mechanical manufacturing industry, machinery in strength member, especially automobile,
The steel part applied in aircraft, rocket nearly all passes through Quenching Treatment, and militarily, gun barrel, and the pipe fitting such as gun tube is even more too busy to get away
Quenching.
To make steel high temperature phase --- austenite is transformed into low temperature metastable phase in cooling procedure --- martensite in quenching,
Cooling velocity have to be larger than the critical cooling rate of steel, and workpiece is in cooling procedure, and the cooling velocity of surface and center portion has necessarily
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 less than critical
The center portion of cooling velocity can not be transformed into the situation of martensite, be needed to ensure all to be changed into whole cross section martensite 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 applications, a kind of continuous pressurizing oil-injection quenching dress is disclosed
Put；It by feeding device, roller-bottom type continuous furnace, take piece manipulator, oil injection quenching press, discharging manipulator, discharging shift
Guipure, oil groove etc. are constituted；Heating furnace is used to make its meet quenching requirement lamellar body progress heating and thermal insulation；Piece manipulator is taken to be up to
Suppress and oil spout quenching in the saw bit matrix feeding oil injection quenching press that quenching is required, hardening media delivers to Quenching press again
Recycle stream oil-recovery tank.Quenching unit in the patent is although simple to operate, and continuous compacting oil spout quenching can be carried out to workpiece,
But, because its oil spout quenching is quenching mode that is being carried out in oil holding slot and using pipeline system, to workpiece
Quenching velocity is limited, can cause that workpiece hardness is small and hardness is uneven, it is impossible to effectively improve its quenching degree.
In Publication No. CN103572035A Chinese patent application, disclose a kind of annular work piece process for quenching and
Quenching unit used in this method；The process for quenching of the annular work piece includes following process：By interior mould be arranged at
Carry out the process of cooling down workpiece in the state of workpiece inner circumferential side after hardening heat heating；Less than 500 DEG C are reached in workpiece temperature simultaneously
And before martensite start temperature is reduced to, if the inner peripheral surface of workpiece starts to be bound, one with interior contacting dies
Side persistently carries out constraint and presses workpiece with low pressure in the direction of the width on one side and workpiece is inserted into the process in outer mold；And
If after workpiece temperature is reached below martensite start temperature, by pressing workpiece in the direction of the width with high pressure, thus
Workpiece is fettered in the direction of the width, and fetters using outer mold the outer peripheral face of the workpiece of volumetric expansion because of martensitic traoformation
Process.
Although refer to the quenching to annular work piece in the patent, the main purpose of the patent is：In ring-type work
Before the outer peripheral face of part expands because of martensitic traoformation, insert it into outer mold, suppress the outer peripheral face and outer mold of workpiece
Contact and produce cut, reduce the allowance of the grinding of workpiece, so as 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 interior mould is assigned inside annular work piece, instead
And cooling velocity can be reduced, cause workpiece hardness small and hardness is uneven, it is impossible to effectively improve its quenching degree.
In Publication No. CN104232871A Chinese patent application, a kind of train wheel integral quenching new technology is disclosed：
(1) workpiece is loaded into lower vacuum heat-insulation die cavity and lower positioning mould intracavitary first, top die declines with upper vacuum heat-insulation die cavity
Vacuum heat-insulation die cavity clamps workpiece and pressurizeed；(2) the Integral quenching device rapid decrease of above-mentioned clamping workpiece and immerse quenching it is cold
But in medium, vibration is descended on the whole, is moved horizontally, the stirring of quenching medium jet flow；(3) after cooling terminates, rise overally, on
Pressing mold is lifted with upper vacuum heat-insulation die cavity, and workpiece is drawn off.
But the type of cooling is to clamp the Integral quenching device rapid decrease of workpiece and immerse quenching cooling to be situated between in the patent
In matter, vibration is descended on the whole, is moved horizontally, quenching medium jet flow stirring, although quicker than usual manner, but quenching cooling
Medium overall flow difference can cause quenching degree, the problems such as hardness is uneven.
