Abstract
The utility model discloses an inner tooth ring pressure quenching device comprising a mould core (2) and a mould core cover plate (1) which are connected with each other through a bolt, wherein an oil hole (3) is formed in the mould core (2). According to the inner tooth ring pressure quenching device, a mould has the effects of reducing deformation of workpieces during quenching and ensuring the accuracy of the workpieces.
Description
Technical field
The utility model relates to a kind of ring gear and presses quenching device.
Background technology
Large ring gear is due to highly higher, and wall is thinner, adopts traditional pressure mould of quenching to press while quenching, and because seam portion has core rod, supports, and can shrink generation tapering, thereby not reach design requirements, can not meet mounting condition.
Summary of the invention
For addressing the above problem, the utility model provides a kind of ring gear to press quenching device, and this mould can reduce workpiece distortion when quenching, and guarantees the mould of workpiece accuracy.
The utility model has adopted following technical scheme: a kind of ring gear is pressed quenching device, core rod and core rod cover plate, consists of, and both are bolted, and are provided with away oilhole on core rod.
The described below car of walking oilhole has annular recess; Described core rod cover plate is comprised of two circular cover, and the size of the circular cover in outside and the path of ring gear match, and size and the core rod of the circular cover of inner side match.
The utlity model has following beneficial effect: the ring gear mould structure that the utility model provides is simple, easy for installation; Apply this ring gear mould and press while quenching, workpiece is enclosed within on core rod, seam oil spout is upward pressed and quenched, and can suppress well distortion, well eliminates the tapering that has guaranteed ring gear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is that a kind of ring gear is pressed quenching device, core rod 2 and core rod cover plate 1, consists of, both are bolted, and are provided with away oilhole 3 on core rod 2, described in walk oilhole 3 below car have annular recess, for oily play, can make quenching oil more even; Described core rod cover plate 1 is comprised of two circular cover, and the size of the circular cover in outside and the path of ring gear match, and the size of the circular cover of inner side and core rod 2 match, and that avoids core rod 2 walks oilhole 3 simultaneously.
Claims (3)
1. ring gear is pressed a quenching device, it is characterized in that being comprised of core rod (2) and core rod cover plate (1), and both are bolted, and are provided with away oilhole (3) on core rod (2).
