Abstract
The utility model relates to a tooling, in particular to a carburizing and quenching tooling of a gear hub, which pertains to the technical field of heat treatment. The carburizing and quenching tool comprises a circular main body; and the outer diameter of the circular main body is matched with that of a center hub of the gear, the inner diameter of the main boy is larger than or equal to that of the center hub, and two end surfaces of the main body are respectively distributed with supporting blocks with equal height at intervals. When in use, the carburizing and quenching toolings are arranged among a group of gear hubs which are stacked up and are to be carburized and quenched, and are aligned to the center hub of the gear, thus leading to smooth flow of quenching oil at the hub and good cooling effect due to the intervals among the supporting blocks, and further being beneficial to improving the quenching effect of heat treatment and reducing deformation of the gears. Simultaneously, the carburizing and quenching tooling has an integral structure, therefore, the tooling does not shift in carburization and quenching, thus guaranteeing hoisting safety in carburization and quenching, and reducing deformation of the gears.
Description
Technical field
The utility model relates to a kind of frock, and especially a kind of gear wheel hub carburizing and quenching frock belongs to the heat treatment technics field.
Background technology
Understand according to the applicant, the high-speed heavy loading locomotive gear requires to harden in hub positions.This type gear is special-shaped asymmetric gear, and general gear hub positions does not require hardens, and is the stack shove charge in the shove charge of carburizing and quenching process middle gear, and middle hub positions does not separate.In the past, can only use the arc cushion block to this type of high-speed heavy loading locomotive gear that requires to harden.Because the contact area of cushion block is bigger, cooling oil enters area and reduces during quenching, and wheel hub quenching quality is had a negative impact; Because cushion block separates placement, very easily in the carburizing and quenching process, be subjected to displacement, even fall in the quenching tank in addition, thereby also can have a negative impact the lifting safety of carburizing and quenching, the distortion of gear (as face runout, gear disc distortion).
The utility model content
The purpose of this utility model is: the problem at above-mentioned prior art exists proposes a kind of gear wheel hub carburizing and quenching frock that helps to guarantee the gear thermal treatment quality.
In order to reach above purpose, gear wheel hub carburizing and quenching frock of the present utility model comprises annular body; The external diameter of the external diameter of described annular body and the center hub of described gear matches, and internal diameter is more than or equal to the internal diameter of described center hub, and both ends of the surface are intervally distributed with highly consistent back-up block respectively.
During use, the carburizing and quenching gear wheel hub is each other every putting frock of the present utility model one group for the treatment of of stacking, and make it to align with the center hub of gear, like this, by the interval between the back-up block, can make the circulation of hub positions quenching oil smooth and easy, good cooling results, thereby help to improve the heat-treatment quenching quality, reduce gear shifting quadrant texturing.Simultaneously,, therefore in the carburizing and quenching process, can not be subjected to displacement, thereby the lifting safety of assurance carburizing and quenching reduces gear shifting quadrant texturing because frock of the present utility model is an one-piece construction.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the perspective view of Fig. 1.
Fig. 3 is the user mode synoptic diagram of Fig. 1 embodiment.
Embodiment
Embodiment one
The gear wheel hub carburizing and quenching frock of present embodiment as depicted in figs. 1 and 2, comprise annular body 1, the internal diameter and the external diameter of the central axle sleeve of the internal diameter of annular body 1 and external diameter and gear wheel hub match, one group of eight back-up block 2 that both ends of the surface are highly consistent uniformly at intervals respectively.During concrete the manufacturing, according to the forged annular body 1 of the size design of gear wheel hub, in addition, back-up block 2 is along the circumference of annular body uniform distribution radially, shape (back-up block sum n can change as required, forms 360 °/n angle between adjacent two back-up blocks) in angle of 45 degrees between adjacent two back-up blocks, behind uniform distribution on the forged circumferential body both ends of the surface, welding is fixing, carries out turning again, guarantees the parallelism of upper and lower end face.Usually the back-up block sum is at least 3, is advisable with 4 to 8.
During use, as shown in Figure 3, on the lifting chassis 6 of center fixation suspension rod 3, place this frock earlier, again gear 4 is lain on this frock, and the like, until the suitable number of plies.By the interval of the frock back-up block of present embodiment, guaranteed that the gear hub positions has sufficient carburizing atmosphere circulation, quenching oil can smooth and easy circulation during quenching.And because the gear spacing increases, the support of being convenient to the adjustable preventing deformation bolt 5 in gear border is installed, and helps to reduce that gear face is beated and the distortion of gear disc.
Big with the arc cushion block contact area of present use, cooling oil enters shortcomings such as area reduces and compares when quenching, the frock of present embodiment has reduced the contact area with the gear wheel hub, the circulation of carburizing atmosphere and quenching oil is smooth and easy when helping carburizing, improved the effect of hardening.Conclusion is got up, and present embodiment has following outstanding advantage:
1, frock is inserted in the carburizing and quenching suspension rod, can not slip into quenching tank, has guaranteed lifting safety.
2, increase height between gear, be convenient to the installation of the adjustable preventing deformation bolt in gear border, reduced the distortion of face runout and gear disc.
3, help the circulation of the carburizing atmosphere of hub positions between gear and quenching oil, make the above and below cooling of gear more even, being more evenly distributed of stress field during quenching reduced the tapering up and down of gear.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
