Abstract
The utility model discloses a kind of thin-walled synchronous ring quenching frock for the press quenching of synchronous ring manufacturing processed.It comprises counterdie, patrix, quenching mandrel and coupling shaft, and quenching mandrel connects firmly on patrix by coupling shaft; Counterdie has ring groove and annular table.The utility model is that existing pressure side face quenching frock is changed to the face quenching frock of presenting a theatrical performance as the last item on a programme, and while quenching, workpiece large end face contacts with patrix, and workpiece table top is placed in the mould contact of annular table up and down, and workpiece small end face is placed in ring groove.The utility model presses the dimensional uniformity of quenching good, has improved the qualification rate of the radial and axial size of workpiece; Quenching quality is high, good reliability, has prevented from pressing the distortion of thin-walled synchronous ring after quenching, and has improved product processing quality.
Description
Technical field
The utility model relates to a kind of synchronous ring quenching frock, specifically a kind of thin-walled synchronous ring quenching frock.
Background technology
Synchronous ring is the vitals of synchronizer of automotive gear box.In synchronous ring manufacturing processed, the press quenching procedure that is absolutely necessary, due to needs thermal treatment, causes synchronous ring distortion very large.
The press quenching of existing synchronous ring adopts presses end hardening.As shown in Figure 3, pressure side face quenching frock comprises counterdie 1, patrix 4 and quenching mandrel 2, according to the difference of workpiece 9, the size difference of quenching mandrel 2, to ensure that workpiece axial dimension (planeness) and radial dimension (circularity) reach processing requirement, when work, workpiece 9 is enclosed within on quenching mandrel 2, by counterdie 1 and patrix 4 matched moulds, then quench, while utilizing workpiece 9 to quench, shrink and be fitted on inner conical surface to ensure circularity, there is pressure in upper/lower die when shrinking always, qualified to ensure the planeness of workpiece 9 large end faces and small end face.
The defect of above-mentioned existing quenching frock is: for thin-walled and the reeded synchronous ring workpiece of small end face, when quenching, the reeded place of small end face is only subject to counterdie power upwards on corresponding large end face, and be not subject to the downward power of patrix, cause the large end face of the fluted position of small end face upwards to shrink, and small end face other do not have reeded place to be subject to the power of upper and lower mould, the trend that has stoped large end face upwards to shrink simultaneously.Due to this species diversity, cause the planeness of synchronous ring workpiece large end face to be difficult to ensure, cause workpieces in subsequent processing difficulties, even scrap.
Utility model content
The utility model object is: the defect existing for existing quenching frock, and provide one can ensure that workpiece presses quench axial dimension and radial dimension, prevent from pressing the thin-walled synchronous ring quenching frock of synchronous ring distortion after quenching.
To achieve these goals, the utility model is by the following technical solutions:
Thin-walled synchronous ring quenching frock, comprises counterdie, patrix, quenching mandrel and coupling shaft, and quenching mandrel connects firmly on patrix by coupling shaft; Counterdie has ring groove and annular table.
The utility model is that existing pressure side face quenching frock is changed to the face quenching frock of presenting a theatrical performance as the last item on a programme, and when quenching, workpiece large end face contacts with patrix, and workpiece table top is placed in the annular table up and down mould contact of counterdie; Annular table plays supporting workpiece table top, applies a uniform power upwards in the time quenching.Workpiece small end face is placed in the ring groove of counterdie, because workpiece small end face is not subject to upper die and lower die applied pressure, thereby can not affect the stressed distortion that causes workpiece large end face of workpiece large end face.After upper die and lower die matched moulds, quenching mandrel drops on workpiece inner conical surface, patrix contacts with workpiece large end face, now workpiece table top and workpiece large end face are simultaneously stressed, have ensured axial dimension (end face planeness) and radial dimension (circularity) when the reeded synchronous ring workpiece pressure of thin-walled and small end face is quenched.
Effect of the present utility model is: compared with existing frock, the utility model presses the dimensional uniformity of quenching good, has improved the qualification rate of the radial and axial size of workpiece; Quenching quality is high, good reliability, has prevented from pressing the distortion of thin-walled synchronous ring after quenching, and has improved product processing quality.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1 and Figure 2, the utility model comprises counterdie 1, quenching mandrel 2, coupling shaft 3 and patrix 4.Counterdie 1 has ring groove 7 and annular table 8; Quenching mandrel 2 connects firmly on patrix 4 by coupling shaft 3, and fastening by packing ring 5 and nut 6.
The utility model is that existing pressure side face quenching frock is changed to the face quenching frock of presenting a theatrical performance as the last item on a programme.When quenching, workpiece large end face A places upward, contacts with patrix 4; Workpiece table top B is placed in annular table 8 up and down moulds 1 and contacts, and annular table 8 plays the workpiece table top B of support, applies a uniform power upwards in the time quenching.Workpiece small end face C is placed in ring groove 7, because workpiece small end face C is not subject to patrix 4 and counterdie 1 applied pressure, thereby can not affect the distortion of the stressed workpiece large end face A causing of workpiece large end face A.After patrix 4 and counterdie 1 matched moulds, it is upper that quenching mandrel 2 drops on workpiece inner conical surface D, and patrix 4 contacts with workpiece large end face A, and now workpiece table top B and workpiece large end face A are simultaneously stressed.When quenching, workpiece inner conical surface D shrinks, the male cone (strobilus masculinus) of workpiece inner conical surface D and quenching mandrel 2 is fitted completely, play the effect that ensures workpiece 9 radial dimensions (circularity), and the axial dimension of workpiece 9 in the time shrinking because workpiece table top B and workpiece large end face A are evenly subject to patrix 4 and counterdie 1 applied pressure, therefore shrink high conformity, ensured the axial dimension (workpiece end face planeness) of workpiece 9, for the processing quality of subsequent handling provides guarantee.
Claims (1)
1. thin-walled synchronous ring quenching frock, comprises counterdie, patrix and quenching mandrel, it is characterized in that: described frock is also provided with coupling shaft, and quenching mandrel connects firmly on patrix by coupling shaft; Described counterdie has ring groove and annular table.
