Description
Technical field
This practical disk gear quenching prevents the technical field of heat treatment technology of being out of shape.
Background technology
Most gear in use all needs to apply suitable load, makes it bend, and produces stress under compression.Want to make gear material reach these performance requriementss, will heat-treat it, along with the carrying out of quenching process, generation is out of shape by disk gear.In order to pinion distortion and obtain stable tolerance of dimension, adopt Quenching press to utilize the disk gear die set that quenches to quench to disk gear, thus decrease distortion, ensure that quality.
Utility model content
The technical problem that the utility model solves deforms when being and preventing disc type gear from quenching.
The technical solution adopted in the utility model is disk gear quenching molding press device, Quenching press worktable center is provided with groove, the boss of groove and disk gear lower surface is suitable, the compression of disk gear upper surface compressible type ring, die mould ring is provided with spline, spline is meshed with gear, adjusting pad is provided with above die mould ring, adjusting pad is by the driving of Quenching press power set, the groove center of press worktable is also provided with pin-and-hole, steady brace is provided with in pin-and-hole, steady brace and pin-and-hole keep gap, the through hole at steady brace upper end and disk gear center is suitable, steady brace center is provided with through hole, steady brace hole wall is provided with at least two nozzle openings.
Die mould ring and disk gear position of fitting is provided with arc groove.
Die mould ring external diameter increases from the bottom to top gradually.
Nozzle opening is 4 groups, often organizes the arrangement of nozzle opening vertical direction, and each group nozzle opening relative positioning pin axis is symmetrical.
The beneficial effects of the utility model are, by the location to gear, avoid the distortion of part in quenching process, be all provided with allow the free-pouring hole of quenching oil, uniform quenching to gear between the parts position and gear, avoid producing stress.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Disk gear 5 of the present utility model quenches Compression mould apparatus, comprise Quenching press, groove 6 is provided with in Quenching press worktable 4, groove 6 is locating surface, suitable with the boss of disk gear 5 lower surface, die mould ring 2 external diameter increases from the bottom to top gradually, is provided with adjusting pad 1 above die mould ring 2, adjusting pad 1, by the driving of Quenching press power set, compresses disk gear 5 downwards.Press worktable 4 groove 6 center is also provided with pin-and-hole, steady brace 3 is provided with in pin-and-hole, steady brace 3 and pin-and-hole keep gap, the through hole at steady brace 3 upper end and disk gear 5 center is suitable, steady brace 3 is provided with through hole in center, steady brace 3 sidewall is provided with at least two nozzle openings 31, nozzle opening 31 and by can allow that quenching oil flows in part.
When disk gear 5 Quenching Soaking Time to be processed reach come out of the stove condition time, move to rapidly on press worktable groove 6, the steady brace 3 at worktable groove 6 place rises, and fits, play positioning action to disk gear 5 with disk gear 5 endoporus.Quenching press decline applied pressure is contacted with disk gear 5 spline place by the spline position of die mould ring 2, ensures that disk gear 5 is parallel without boss face.
Install the die set that quenches, regulate adjusting pad 1 simultaneously, ensure the level turnover action of worktable, on platform, disk gear 5 is 3-5mm with mould the top distance.
Quenching die mould ring 2 has arc groove with disk gear 5 contact site, and steady brace 3 center is provided with through hole simultaneously, and hole wall is provided with nozzle opening 31, is used for ensureing the flowing repeatedly of quenching oil, reaches good quenching effect.
Start press and perform quenching, quenching die set repeats vibrations up and down and contacts with disk gear 5, hardening liquid is spray disk gear 5 from steady brace 3 surrounding nozzle opening 31 rapidly, first harden in disk gear 5 surface, then die set continues the compression disk gear 5 that declines, now disk gear 5 is fully immersed in hardening liquid, continues cooling through hardening.
After the scheduled time, hydrojet stops, and quencher's station, disk gear 5 and die mould ring 2 rise, and steady brace 3 declines, and depart from from disk gear 5 endoporus, disk gear 5 shifts out automatically with worktable from press.
