Description
Technical field
This utility model relates to induction heat treatment technical field, especially a kind of quenching inducer for low-speed big live axle。
Background technology
Low-speed big live axle (material 42CrMo steel) is the key on high-power (more than 160 horsepowers) wheeled tractor, safety feature, for meeting tractor demand of farming and transport under different operating modes, the structural design relative complex of live axle, and version can not arbitrarily change, otherwise can make partial loss of function, reducing the usability of tractor, severe patient even has influence on the safety of complete machine。The load that this live axle bears in low-speed big work process is mainly bent/twisted alternate load so that its top layer subjects the stress higher than heart portion, meanwhile, because using inclement condition, very easily cracks, causes early fracture。For improving the service life of such live axle, this part heat treatment of current designing requirement is modified+mid-frequency induction hardening, impewdance matching layer requires relatively deep and continuous, and to bottom the tooth bar of part, keyway, spline and the impewdance matching layer depth at each step place propose and clearly require, must there is suitable hardened depth, to obtaining good mechanical performance。
At present, the induction heat processing method of relevant to low-speed big live axle axial workpiece is analyzed as follows:
1, the induction heat processing method with tooth bar axial workpiece
(1) contact induction heat treatment, carries out selective hardening process to tooth bar class part, and its quench-hardened case is at below 2mm, and quenching quality is good。
But it is disadvantageous in that: the method cannot realize having the requirement of the live axle induction heat treatment of tooth bar, keyway, multi-step and four kinds of structure types of spline simultaneously, can not realize very deep quench-hardened case。
(2) stage-hardening, it may be achieved the surface peening of part zones of different, meets the technology requirement of each portion faces strengthening of tooth bar, improves the practicality of part。
But it is disadvantageous in that: stagewise induction heat processing method makes to exist in the middle of each region of part quenching transition region, and this district's impewdance matching floor is weak link, and namely impewdance matching layer is discontinuous。
2, the induction heat processing method of step axial workpiece
(1) rectangular loop induction apparatus one piece heating, it is ensured that spline and boss and bar portion hardened layer uniformly continuous。Overall heating manufacturability is better, and part deformation is little, it is simple to realizing automatization, productivity ratio is higher。
But it is disadvantageous in that: this induction heat processing method needs sizable power, is difficult to because of the limitation of conditions in big-powered tractor low-speed big live axle induction heat treatment and adopts。
(2) annular laser heating quenching mode successfully solves the induction heat treatment requirement of big reducing step axial workpiece, and below 100 horsepowers, the part such as the live axle of tractor, power output shaft is well used, and obtains good economic benefits。
But it is disadvantageous in that: the method cannot realize having the requirement of the low-speed big live axle induction heat treatment of tooth bar, keyway, multi-step and four kinds of structure types of spline simultaneously, and due to the kelvin effect principle of induction heat treatment, directly use this method, can cause and not reach hardening heat bottom part such as tooth bar, and the phenomenon that its tip is overheated, it is impossible to realize expection purpose。
3, the induction heat processing method of semiaxis
(1) annular induction apparatus continuous heat processing method, its induction apparatus passes through particular design, improves its efficiency of heating surface, reduces the degree of superheat of boss face, to ensure each cross section homogeneous heating。
This technical scheme mainly solves the intensity of ring flange arc surface, improves the performance of semiaxis, but is disadvantageous in that: if this induction heat processing method is used for heating tooth bar, will be unable to realize flank of tooth homogeneous temperature, thus producing quality accident。
(2) bigger semiaxis factory, for improving productivity ratio, often selects heat treatment method of rectangle induction apparatus, and the method needs to select high power frequency conversion power supply, devises energy controller for this research worker, thus controlling thermal treatment quality。
But being disadvantageous in that: heat treatment method of rectangle induction apparatus, needing bigger power supply and auxiliary facility complicated, cost is high, is unsuitable for the induction heat treatment of high-power wheeled tractor low-speed big live axle。
From technical standpoint analysis, the surface peening at tooth bar, keyway, step and spline position is induction heat treatment difficult point, but high-power wheeled tractor low-speed big live axle part is substantially all and has tooth bar, keyway, step and four kinds of structure types of spline simultaneously, and larger in size (length is be more than or equal to 800mm, the diameter of axle is be more than or equal to 60mm), the induction heat treatment difficulty of part is bigger。The existence of these structures causes part when sensing heating owing to the reason of kelvin effect, sharp angle effect causes subregion non-uniform temperature, local temperature is difficult to reach hardening heat, cause that quenching layer is discontinuous, and piece surface fluctuation is big, during quenching, hardening crack tendency strengthens, and the quench-hardened case of this kind of part requirements is relatively deep simultaneously, with high content of technology, impewdance matching difficulty is big, its difficult quality guarantee of quenching, belongs to sensing heating knotty problem。
