Description
Technical field
The invention belongs to hydraulic pump field more particularly to a kind of heat treatment works of the copper steel dual alloy blank of hydraulic pump
Dress.
Background technique
Copper steel pairing metal parts refer to the part manufactured by copper steel dual alloy material, and copper steel dual alloy material is by relatively thin
The material that layers of copper and thicker steel layer are combined into.Copper steel pairing metal parts have extensive in hydraulic pump (also known as hydraulic motor)
Application, be mainly used in the friction pair accessory of hydraulic pump, while with higher-strength, also have preferable abrasion-resistant
Property and fatigue resistance.It when copper steel pairing metal parts produce, needs first to process blank with copper steel dual alloy material, then by blank
Part is directly heat-treated (quenching treatment, rapid cooling after heating), makes the steel layer strength enhancing of blank, finally by blank
Finishing obtains finished product.Blank is in heat treatment, since the thermal expansion coefficient difference between layers of copper and steel layer is larger, blank
Rapid cooling can make the faying face between layers of copper end face and layers of copper and steel layer generate larger tensile stress, may result in blank
Layers of copper occur cracking or layers of copper separated with steel layer, the heat treatment qualification rate of blank is low, only 30% or so.
Therefore, blank, which directly carries out being heat-treated, haves the shortcomings that qualification rate is low.
Summary of the invention
The object of the present invention is to provide a kind of heat treatment toolings of copper steel dual alloy blank.Existing blank uses
The present invention carry out heat treatment have the advantages that qualification rate is high, the present invention with the processing is simple, be easily installed with it is reusable
Advantage.
Technical solution of the present invention: a kind of heat treatment tooling of copper steel dual alloy blank, including pedestal, pedestal are equipped with
Blind hole, blind hole is interior to be equipped with heat insulating mattress, and pedestal is equipped with fixed structure.
In the heat treatment tooling of copper steel dual alloy blank above-mentioned, the heat insulating mattress is asbestos pad.
In the heat treatment tooling of copper steel dual alloy blank above-mentioned, heat insulating mattress with a thickness of 3-8mm.
In the heat treatment tooling of copper steel dual alloy blank above-mentioned, the fixed structure is to be set on blind hole inner wall
Internal screw thread.
Compared with prior art, blank will be installed on the present invention to be heat-treated, the steel layer of blank is largely sudden and violent
It is exposed to outside pedestal, a part of steel layer and whole layers of copper reduce layers of copper at blank heat in pedestal, through pedestal and asbestos pad
The cooling velocity during rapid cooling is managed, after keeping steel layer cooling, layers of copper is still in the condition of high temperature, at this point, layers of copper still has
There are the higher coefficient of expansion and plasticity, the tensile stress between layers of copper and steel layer can be reduced, prevents the layers of copper of blank from cracking
Or layers of copper is separated with steel layer, improves the qualification rate of blank heat treatment.It is found through experiment that blank, which is installed on the present invention, carries out heat
Processing, heat treatment qualification rate is up to 85% or more, compared to the blank being directly heat-treated, intensity, rub resistance and anti-
Fatigability is also held essentially constant, and meets requirement after being processed into accessory.Moreover, the configuration of the present invention is simple, so that processing letter
List is easily installed, also reusable.
Therefore, blank using the present invention carry out heat treatment have the advantages that qualification rate is high, the present invention with the processing is simple,
It is easily installed and reusable advantage.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 blank is installed on schematic diagram of the invention.
The label in accompanying drawing is: 1- pedestal, 2- blind hole, 3- heat insulating mattress, 4- fixed structure, 5- layers of copper, 6- steel layer.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment 1.A kind of heat treatment tooling of copper steel dual alloy blank, as shown in Figure 1, including pedestal 1, on pedestal 1
Equipped with blind hole 2, heat insulating mattress 3 is equipped in blind hole 2, pedestal 1 is equipped with fixed structure 4.
The heat insulating mattress 3 is asbestos pad.
Heat insulating mattress 3 with a thickness of 3,5 or 8mm, the internal diameter of the diameter of heat insulating mattress 3 close to blind hole 2.
The fixed structure 4 is the internal screw thread being set on 2 inner wall of blind hole.
The circumferential surface of pedestal 1 is equipped with pin shaft hole.
Blank (in blank layers of copper material of the above-mentioned tooling for YZBXX-3005 type dual alloy rotor in hydraulic pump
QSn6.5-0.1, steel layer material 40CrNiMoA) heat treatment when, first blank have layers of copper one end external threading, outer spiral shell
Line extends on the outer peripheral surface of steel layer, then write off axis is inserted into pin shaft hole, then pedestal 1 is set on blank, makes internal screw thread
It is engaged with external screw thread, is rotated using pin shaft band moving base 1, be fixed to pedestal 1 on blank, complete blank and of the invention
Installation.Dual alloy rotor is heat-treated using the present invention, the qualification rate of heat treatment can be increased to 85% from 30%.Blank
After completing heat treatment, the external screw thread on surface can remove in subsequent finishing passes.
Blank (in blank layers of copper material of the above-mentioned tooling for YZBXX-2001 type dual alloy rotor in hydraulic pump
ZQSn10-2-3, steel layer material 30Cr3WVE) heat treatment when, blank and mounting means of the invention and above-mentioned mounting means
Identical, the qualification rate of heat treatment can be increased to 87% from 35%.
Therefore, blank using the present invention carry out heat treatment have the advantages that qualification rate is high, the present invention with the processing is simple,
It is easily installed and reusable advantage.
