Abstract
The invention discloses a pressure quenching mould for an inner ring gear. The pressure quenching mould is composed of a mould core (2) and a mould core cover plate (1) which are connected with each other by a bolt, wherein the mould core (2) is provided with an oil passing hole (3). According to the pressure quenching mould for the inner ring gear, the deformation of a workpiece can be alleviated in the quenching process and the precision of the workpiece can be guaranteed.
Description
Technical field
The present invention relates to a kind of ring gear and press the mould of quenching.
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 section has core rod, supports, and can shrink the generation tapering, thereby not reach design requirements, can not meet mounting condition.
Summary of the invention
For addressing the above problem, the invention provides a kind of ring gear and press the mould of quenching, this mould can reduce workpiece distortion when quenching, and guarantees the mould of workpiece accuracy.
The present invention has adopted following technical scheme: a kind of ring gear is pressed the mould of quenching, and 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 the outside and the path of ring gear are complementary, and size and the core rod of inboard circular cover are complementary.
The present invention has following beneficial effect: ring gear mould structure provided by the invention 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is that a kind of ring gear is pressed the mould of quenching, and 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, and the described below car of walking oilhole 3 has 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 the outside and the path of ring gear are complementary, and size and the core rod 2 of inboard circular cover are complementary, and that avoids core rod 2 walks oilhole 3 simultaneously.
Claims (3)
1. a ring gear is pressed the mould of quenching, and 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).
