Description
Technical field
The present invention relates to a kind of ring parts and sense process and the equipment of orthopedic mold pressing Q-tempering.
Background technology
Generally to be improved bearing capacity and the life-span of part by heat treatment in machine components manufacture process.For thin-walled ring
Class part after heat treatment deforms relatively big, and including losing circle, interior space-variant cone, plane warping etc., percent defective is higher.At present to deformation
The mechanism produced is to use press quenching mode also in conceptual phase, the means of relatively effective suppression deformation.It it is i.e. employing one
Individual external-heat heating furnace, workpiece heat to hardening heat, is then transferred in a device with mechanically dip mold adding necessarily
Pressure and quench.An inflatable core is the most also included in order to position pressing mold.Unclamp dip mold after having quenched then will
Workpiece need to clean and transfer to be tempered in another one heating furnace, completes heat treatment step.
Heating furnace is usually the external-heat cycle such as electric heating, combustion gas stove or the continous way such as annular furnace, converter.Owing to workpiece is at height
Shifting under temperature state, therefore transfer device wants to clamp the part of heat, more complicated.Upper dip mold has for reducing plane warping
Certain effect, but thermal expansion mould is the most reliable for the control of Roundness of Workpiece；If using overall core, then due to quenching
Time contraction, workpiece to be unloaded down tempering and be necessary for being extracted by core by the biggest external force, and this often results in mandrel surface very
To pulling of inner hole of workpiece, die life is short, and cost is high.
Conventional method need to be many with equipment, and intermediate transfer uses artificial then labour intensity big；Especially in heating process by
Being installed and mistake circle that the factor such as deadweight causes in workpiece, conventional die quenching method can not be improved.Therefore, qualification rate phase
To relatively low.
Summary of the invention
It is an object of the invention to provide a kind of ring parts and sense process and equipment, the method for orthopedic mold pressing Q-tempering
The mistake circle etc. caused in part operation before heat treatment can be corrected deform, the deformation of heat treatment process can be limited again, significantly simultaneously
Improve the qualification rate that ring parts is heat-treated.
The method of the present invention is to use a set of sensing heating and mould pressing Q-tempering equipment to carry out part at whole Q-tempering heat
The operation of science and engineering sequence；Its equipment includes induction heating power, the quenching machine implementing whole process actions and cooling water, quenching liquid
EGR.Wherein the executing agency of the parts such as heating inductor, quenching liquid ejection cartridge, upper dip mold, core and motion thereof with
And workpiece grip mechanism is installed on the framework of quenching machine.Induction heating power and cooling water, quenching liquid EGR pass through
Pipeline and the heating inductor of lathe, upper dip mold and core and quenching liquid ejection cartridge and drive mechanism thereof are connected, and pass through
Machine tool control system completes whole program behavior.Its step:
First workpiece use manual or automatic mechanism by workpiece feeding to lower bearing support, and by the inductor of cincture by workpiece
It is heated to hardening heat.Carry out subsequently correcting and die quenching step:
Induction heating power cuts off, and be positioned on lower support mould is heated on the annular workpieces of hardening heat by an insertion
The overall core location in hole, with orthopedic, is pushed down by mechanical force by the top die being positioned on same axis immediately, and now inductor moves
Move the quenching ejection cartridge closed on and be positioned on same axis and move to the quenching position of workpiece, the quenching liquid injection apparatus of surrounding and
The ejection channel of mould inside under external control simultaneously or successively flash quenching liquid complete quenching, injection stops；Now workpiece by
Hug on core in contraction, carry out induction tempering step subsequently:
Quenched outside ejection cartridge leaves quenching position；Inductor moves on to heating location；Now induction heating power is open-minded, sensing
Workpiece, by between upper dip mold and the quenching workpiece that hugs on core is heated to temperature, is tempered by device.After tempering
Owing to the thermal expansion at this moment core of workpiece can easily deviate from workpiece.Workpiece is cooled to temperature the blanking subsequently that can shift.
Described each step successively order be feeding, sensing heating, insert core, upper and lower die quenching, induction tempering with under
Material.
Described each step can use same set of induction heating power and same set of mould to complete on a station.Also may be used
To complete on adjacent station.Wherein the movement between inductor and workpiece is relative, can be i.e. workpiece (or workpiece
And mould) mobile, it is also possible to it is that inductor moves；The mechanical mechanism being moved through lathe of each assembly realizes；
Described core is relevant with workpiece shapes and final size, the high-precision solid or mould of hollow structure, its
Material is nonmagnetic or weak magnetic；Hollow core has hole in its surface as required, and lower end is connected with the quenching liquid circulatory system
Connect, have quenching liquid to spray from hole in quenching process, the inner surface of Cooling Quenching workpiece；Owing to the size of core is more than reality
The hole size of part, therefore, in quenching process, ring-shaped work pieces can shrink and hold tightly at mandrel surface, thus reaches orthopedic and limit
Rounding degree, the effect of tapering.
Described core shape is relevant with workpiece shapes and final size, and its profile can be that cylinder is (when in workpiece
When hole is cylinder), it is also possible to it is that the column of uniform or non-uniform band tooth is (when the surface that inner hole of workpiece is band tooth
Time)；
Described top die and lower support mould, with to be quenched accessory size relevant, core can be processed as required or not
Processing quenching liquid duct.When workpiece quenching, lathe applies certain mechanical pressure and passes to quenching workpiece through upper dip mold, with
Time quenching liquid spray to from the duct of quenching liquid ejection cartridge and upper dip mold workpiece (the need to), reach uniform hardening and restriction
The purpose of plane deformation；
Described upper dip mold and workpiece keep revolution by mechanical mechanism during heating and pressure are quenched, not only make heating and
Cooling is uniform, and beneficially Reducing distortion.Rotating speed can be that constant speed can also speed change；
Described quenched the quenching liquid flow of box injection and temperature-controllable by upper dip mold and outer workpiece, cooling order and
It is spaced the most controlled.
It is an advantage of the invention that the method can complete the whole heat treatment process of Q-tempering of annular workpieces on an equipment, whole
Individual system needs equipment few, compact conformation, and floor space is little.
It is an advantage of the invention that accurate core be in the case of gapless restrained deformation but enter and leave under having gap state
Quenching workpiece, thus it is little to wear and tear, the life-span is long.
It is an advantage of the invention that the pattern heated parts using sensing heating, heated by inside workpiece eddy current, heating speed
Degree is fast, and electric conversion efficiency is high, energy-conservation.
It is an advantage of the invention that the quenching liquid of employing is that water base polymer is easy, during quenching, non smoke is polluted and need not volume
Outer matting；Save transfer device and extra human cost.
