Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Gear ring type parts quenching press clamp structure as shown in Figure 1, Figure 2, Figure 3 shows, including press base platform 9, described
Being provided with annular gear structure 8 on press base platform 9, in described annular gear structure 8, socket is provided with the core 4 that rises, described in the core 4 that rises overlap
Connecing and be provided with combination dilator 2, described combination dilator 2 is made up of dilator top 24, pad 22 and dilator bottom 21, institute
State pad 22 to be fixed between dilator top 24 and dilator bottom 21 by dismountable pad fixing device 23.
Bright spot of the present utility model is: by inner circle ovality after ring gear die quenching and upper and lower tapering change in size
Trend, is adjusted flexibly the thickness of the pad 22 of combination dilator 2, and adjusts the contact position combining dilator 2 and the core 4 that rises, logical
Cross the different-thickness value adjusting pad 22 adjusting combination dilator 2, thus change the contact point of combination dilator 2 and the core 4 that rises
Position, the radial force that the core 4 that reaches to rise transmits to annular gear structure 8 reaches unanimity, and makes the inner headed face of annular gear structure 8 quench whole
Being in basically identical pressure limit shape during fire, geometrical variations trend is consistent, reach annular gear structure about 8 tapering and
Radially ovality relative changing value is less, after the optimum thickness value adjusting pad determines, this sleeve clamp parameter is fixed and is used
In production, there is change in any part of this sleeve clamp, it is necessary to re-start process certification.Wherein, part combination dilator 2 He
The core 4 that rises is the kernel component of this die quenching special fixture, and its accuracy of manufacture is to affect the weight of ring gear distorsion during quenching size
Want factor.Part combination dilator 2 and the core 4 that rises use hot die steel to carry out grinding, size essence after carrying out Quenching Treatment
Degree reaches the requirement of drawing technology, taper fit face carries out coordinating fine grinding, after match grinding completes, carries out linear cutter respectively.Combination
Dilator 2 general line by drawing cutting is divided into 7 parts, cleans stand-by；The core 4 that rises has been measured after height dimension by drawing
Line cuts apart, on request grinding line facet, and grinding simultaneously has completed one group of the pad of heat treatment, the thickness of general pad 22
Degree is suitable for linear cutter size, differ 0.01 respectively, 0.02,0.03,0.05, each two panels of 0.1mm, clean stand-by.
In order to ensure the installation and removal of pad 22 convenient reliably, as shown in Figure 2, described pad can be selected to fix
Device 23 is connecting bolt.
Additionally, in order to change the core 4 asymmetric stress in process of expansion that rises, allow and combine the dilator 2 radial direction to the core 4 that rises
Dissipating component evenly consistent, it is consistent that the core 4 that rises expands outwardly speed, and same circumference rise core tends to one to the pressure of gear ring inner circle
Causing, the core pressure limit shape effect that rises that gear ring inner circle is radially subject in whole quenching cooling procedure reaches unanimity, and reaches ring gear
In quenching process, ovality variation tendency reaches unanimity, and the core 4 that can select to rise described in allowing is by the identical core that rises of odd number structure
Assembly 41 is around composition.As it is shown on figure 3, odd number rises, core assembly 41 allows combination dilator 2 to the radially component of the core 4 that rises more
Uniformity, thus obtain more preferably processing effect.General, preferably described in the core assembly 41 that rises be seven.In order to ensure
Rise core 4 spreading rate uniform when expanding outwardly, and can select to set up socket and be arranged at the support ring 5 of core 4 periphery of rising, described
Support ring 5 is arranged at and rises between core 4 and press base platform 9.
In order to allow combination dilator 2 automatic homing at the end of operation, thus carry out operation next time, can be selected this
The scheme of sample: include that dilator elastic support structure 3, the socket of described dilator elastic support structure 3 are arranged at combination dilator 2
In, described dilator elastic support structure 3 is coaxially arranged with combination dilator 2.Based on same design, in order to allow the core 4 that rises exist
Automatic homing at the end of operation, can select such scheme: include the core elastic support structure 6 that rises, described in rise core resilient support
Structure 6 is arranged at and rises between core 4 and support ring 5.General, dilator center-pole 7 is arranged at above combination dilator 2.
The operation principle of this structure is such that when gear ring quenching carries out die quenching, and mechanical hand is by zero before quenching
Part is positioned over core 4 periphery of rising in situ, starts quenching program, and inner pressure ring 1 and dilator center-pole 7 move down simultaneously, combination expansion
Device 2 moves down, and the core 4 that rises is displaced outwardly contacting with the inner circle of annular gear structure 8 in footpath under the driving of combination dilator 2, in making
The inner headed face of gear ring structure 8 is in basically identical pressure limit shape in whole quenching process, and geometrical variations trend is consistent,
Reach annular gear structure about 8 tapering and radial direction ovality relative changing value is less.After a part die quenching completes, expand
Moving on prop center-pole 7, combination dilator 2 is moved up by the retroaction of dilator elastic support structure 3, reduces the core 4 that rises
Active force, the core 4 of rising is moved to center by the retroaction of the core elastic support structure 6 that rises, and returns in situ, and now mechanical hand will complete
Next station transferred to by gear ring after quenching, and program carries out next circulation.
