Abstract
The utility model relates to a tool for carburizing and quenching a synchronizing cone of an automobile and particularly relates to a mandrel for carburizing, quenching and shaping the synchronizing cone. The mandrel comprises a cylindrical mandrel body, wherein six oil grooves are uniformly and axially disposed on the circumferential surface of the cylindrical mandrel body; and the cross section of each oil groove is rectangular. The synchronizing cone can be carburized and quenched in one time in a heat treatment furnace, thus the production efficiency can be improved by 200%; and due to the arrangement of six oil grooves disposed on the cylindrical mandrel body uniformly, the synchronizing cone can be cooled more uniformly after being quenched, the deformation of the internal spline hole of the synchronizing cone is controlled, the detection by a plug gauge shows that the comprehensive qualification rate of an internal spline is 100%, and the quality of the product is guaranteed.
Description
Technical field
Apparatus when the utility model relates to vehicle synchronous cone carburizing and quenching, particularly a kind of synchronous cone carburizing and quenching setting mandrel.
Background technology
The vehicle synchronous cone needs carburizing and quenching to process before assembling, normally by carburizing in advance, then puts into the fixture second-heating and quenches.Not only increase operation, needed twice loading, unloading stove, inefficiency, and also waste product is many, single-piece synchronous cone M value of internal spline variation≤0.05mm, and with crowd synchronous cone M value of internal spline variation≤0.13mm, comprehensive feeler gauge checks internal spline qualification rate≤70%.
The utility model content
The utility model purpose is to provide a kind of synchronous cone carburizing and quenching setting mandrel, guarantees that synchronous cone M value of internal spline variation is little, product qualification rate reaching 100%.
Technical solutions of the utility model: a kind of synchronous cone carburizing and quenching setting mandrel, comprise cylindrical mandrel, be evenly arranged vertically six oil grooves on the periphery of cylindrical mandrel.
The cross section of described oil groove is rectangle.
Adopt the utility model can once complete carburizing and the quenching two procedures of synchronous cone in heat treatment furnace, production efficiency improves 200%; It is more even when on cylindrical mandrel, six uniform rectangle oil grooves make the synchronous cone quench cooled, controlled the distortion of synchronous cone internal splined hole, single-piece synchronous cone M value of internal spline variation≤0.04mm, with crowd synchronous cone M value of internal spline variation≤0.06mm, comprehensive feeler gauge checks internal spline qualification rate 100%, has guaranteed quality product.
Description of drawings
Fig. 1 is that the utility model uses view.
Fig. 2 is Fig. 1 vertical view (after removing synchronous cone).
In figure: 1 cylindrical mandrel, 2 rectangle oil grooves, 3 synchronous cones (product).
Embodiment
As shown in drawings, during use, the synchronous cone conical surface is stacked on cylindrical mandrel down, together puts into heat treatment furnace, once completes carburizing and quenching two procedures.
Due to cylindrical mandrel and synchronous cone endoporus spline fitted tight, add six rectangle oil grooves that are evenly arranged vertically, changed the loop direction of cooling oil, in heat treatment process, the distortion of synchronous cone endoporus spline obviously reduces, and single-piece synchronous cone M value of internal spline variation≤0.04mm is with crowd synchronous cone M value of internal spline variation≤0.06mm, comprehensive feeler gauge checks internal spline qualification rate 100%, has avoided the generation of substandard product.
Claims (2)
1. a synchronous cone carburizing and quenching setting mandrel, is characterized in that: comprise cylindrical mandrel, be evenly arranged vertically six oil grooves on the periphery of cylindrical mandrel.
2. a kind of synchronous cone carburizing and quenching setting mandrel according to claim 1, it is characterized in that: the cross section of described oil groove is rectangle.
