Face is cone-shaped shaped like the conjunction of upper and lower two cone bottom buckles, and the cone bottom faying face of upper lower cone is seamlessly transitted by curved surface, by this structure
Hole wall combines each regular hexagon honeycomb to be formed, thereon under along open area be all larger than hole inner section product.
In the present invention, the position of annular constant-current support frame is not higher than a quarter of guide shell.
The utility model has the advantage of, due in the utility model guide shell be placed in outer groove and be immersed in quenching cooling
In liquid, guide shell bottom centre be center flow deflector group and its around be uniformly distributed flow deflector group, be all provided in each flow deflector group
There is the flow deflector for extending to entrance, flow deflector forms annular groove in guide shell bottom, quenches coolant liquid can be formed by annular groove one
A face is even into guide shell.Especially be furnished with an all standing annular constant-current support frame, can again profile adjustment quenching it is cold
But the uniformity for going out the water surface of liquid.Since circulating pump uses the speed regulating motor of synchronously control, the annular of an especially all standing is steady
Support frame is flowed, the specific hole wall structure of regular hexagon honeycomb, can further be adjusted in the annular constant-current support frame of covering
With the flow field velocity and flow field quality for improving quenching coolant liquid.Since the position of annular constant-current support frame is not higher than the four of guide shell
/ mono-, it is ensured that guide shell has sufficiently large working space.Since guide shell and outer groove are arranged concentrically, the top of outer groove is
The upper edge hole of necking, guide shell turns up, and the bead of outer groove is greater than the upper edge hole of guide shell, it can be ensured that workpiece to be machined in work
Guide shell can be accurately placed in.Guide shell bead turn up can also to circulation quenching coolant liquid guiding drainage, reduce circulation in
Flow resistance.
The utility model is compact-sized, easy to maintain.
