Description
Technical field
The utility model relates to a kind of synchronous ring quenching frock, specifically a kind of synchronous ring pressure side face quenching frock.
Background technology
In synchronous ring manufacturing processed, press quenching is absolutely necessary a procedure, due to needs thermal treatment, causes synchronous ring to be out of shape very large, if not school shape, then can not meet the needs of workpiece performance, therefore must correct heat treatment of workpieces distortion.
Existing synchronous ring quenching frock comprises counterdie, patrix and quenching mandrel, according to the difference of workpiece, the size of quenching mandrel is different, to ensure that workpiece axial dimension (planeness) and radial dimension (circularity) reach processing requirement, during work, workpiece is enclosed within quenching mandrel, by counterdie and Ccope closing machine, then quench, shrink when utilizing workpiece quenching and be fitted on inner conical surface to ensure circularity, because upper die and lower die exist pressure when shrinking always, ensure that the axial dimension (planeness) of workpiece large end face and small end face is qualified.
The defect of existing quenching frock is: due to this pressure quench frock be by quenching mandrel thickness come spacing, to ensure that upper die and lower die directly do not contact with workpiece end face, and the thickness of workpiece and the thickness requirement of quenching mandrel have very high fitness, not so synchronous ring heat treatment deformation is just large, and end face is lifted up seriously lame.If thickness of workpiece is higher than quenching mandrel, product easily weighs wounded; Require that thickness of workpiece is lower than the thickness of quenching mandrel, but can not lower than too much, otherwise cannot correcting plane degree, therefore require very high to thickness of workpiece, increase the difficulty of processing of product.
Utility model content
The purpose of this utility model is: the defect existed for existing quenching frock, provides a kind of synchronous ring pressure side face quenching frock improving radial and axial size qualification rate when pressure is quenched.
To achieve these goals, the utility model is by the following technical solutions:
Synchronous ring pressure side face quenching frock, comprise counterdie, patrix and quenching mandrel, also comprise backing plate, vexed oil cover, top plate, limited block, locating shaft, oil cylinder link gag lever post, butterfly spring, ejection cylinder, thin cylinder, lower bolster, floating junction, terminal pad and guidepost; Backing plate, counterdie and lower bolster are connected by screw; Quenching mandrel, limited block link gag lever post with locating shaft and oil cylinder and are connected; Oil cylinder link gag lever post is connected with ejection cylinder with butterfly spring; Thin cylinder is connected on top plate; Patrix, floating junction are connected with thin cylinder with terminal pad, and guidepost is connected with patrix, top plate and terminal pad; Vexed oil cover is connected with patrix.
The utility model, by being linked gag lever post, butterfly spring and ejection cylinder formed position-limit mechanism by backing plate, counterdie, lower bolster, quenching mandrel, limited block, locating shaft, oil cylinder, controls quenching mandrel ejection height.Thin cylinder, top plate, patrix, floating junction, guidepost composition floating pressure regulating mechanism, regulates quench pressure.Vexed oil cover controls the distance of patrix and counterdie, eliminates the oil cylinder working-pressure of patrix to the impact of quenching.
During quenching, the large end face of workpiece is positioned on counterdie, the downward matched moulds of top plate is made by oil cylinder working-pressure, after vexed oil cover and counterdie close up, patrix and thin cylinder, floating junction and terminal pad connect to form adjustable jointly, relocatable upper die body, upper die body and counterdie apply corresponding constant pressure to workpiece, according to the size of workpiece, wall thickness, regulate the power of thin cylinder, thin cylinder, top plate, patrix, floating junction, the floating pressure regulating mechanism of guidepost composition, regulate quench pressure, make workpiece both ends of the surface and patrix, counterdie quenches under the effect of controllable force, quenching mandrel rises to fixing height by the position-limit mechanism controlling quenching mandrel ejection height simultaneously, now quenching oil out quenches to workpiece from the outlet-port backing plate, vexed oil cover controls the distance of patrix and counterdie, eliminate the oil cylinder working-pressure of patrix to the impact of quenching, the distortion of calibration of workpieces axial (planeness), but the product not affecting workpiece radial direction (circularity) shrinks, when workpiece is shunk, endoporus is fitted on quenching mandrel completely, after quenching terminates, ejection cylinder moves downward, make product stripping, patrix separates with lower bolster simultaneously, whole quenching process terminates, reach the effect correcting products radial and axial dimension and (both ensure that the end face plane degree of workpiece, in turn ensure that the circularity of workpiece).
Effect of the present utility model is: pressure side face quenching frock quenching frock spacing for end face being changed to adjustable pressure.Be placed on counterdie by the large end face of workpiece, during quenching, small end face contacts with patrix, ensure that the planeness of end face, circularity, corrects heat treatment of workpieces distortion, improves the qualification rate of the radial and axial size of workpiece.Because patrix is floating, even if so the parallelism of workpiece both ends of the surface is bad, also impact is not had during quenching, therefore the difficulty of processing of product is greatly reduced, and the quenching mandrel of quenching frock is spacing by limited block, ensure that the ejection height of quenching mandrel, and then during work-piece cools, workpiece is fitted in the consistent size on quenching mandrel, drastically increases quality product.
