Abstract
The utility model discloses the special frame used by a kind of austempered ductile iron spiral bevel gear austenitizing and isothermal hardening, it is made up of pallet and limitation vertical rod, limitation vertical rod is fixed on the center of pallet, tray upper surface is evenly distributed with several projections.Treat that the spiral bevel gear casting of austenitizing and isothermal hardening is overlayed on pallet with central shaft hole through limitation vertical rod, treat the flank of tooth of austenitizing and the spiral bevel gear casting of isothermal hardening down.Because the nethermost spiral bevel gear casting for treating austenitizing and isothermal hardening is supported by several projections, there is gap between pallet, flank of tooth energy thermally equivalent and the cooling of austenitizing and the spiral bevel gear casting of isothermal hardening are treated, so, reduce or eliminate deflection.
Description
Technical field
The present invention relates to a kind of support, more particularly to a kind of austempered ductile iron spiral bevel gear austenitizing and isothermal hardening institute
Special frame.
Background technology
Existing austempered ductile iron spiral bevel gear in production and manufacturing process, austempered ductile iron spiral bevel gear austenitizing and
Isothermal hardening process, is that spiral bevel gear casting is placed on surface plate to carry out.Due to nethermost spiral bevel gear casting
It is very close to each other between pallet, treat that the flank of tooth of austenitizing and the spiral bevel gear casting of isothermal hardening is heated and inhomogeneous cooling
It is even, it result in deflection excessive.
The content of the invention
The purpose of this utility model is the change in order to solve spiral bevel gear casting during austenitizing and isothermal hardening
The problem of shape amount is excessive, and provide it is a kind of can reduction can eliminate the austempered ductile iron spiral bevel gear austenitizing and isothermal of deformation and quench
Special frame used by fire.
The utility model is made up of pallet and limitation vertical rod, and limitation vertical rod is fixed on the center of pallet, tray upper surface
It is evenly distributed with several projections.
Use process and beneficial effect of the present utility model：
Treat that the spiral bevel gear casting of austenitizing and isothermal hardening overlays pallet with central shaft hole through limitation vertical rod
On, treat the flank of tooth of austenitizing and the spiral bevel gear casting of isothermal hardening down.Treat austenitizing due to nethermost and wait
The spiral bevel gear casting of temperature quenching is supported by several projections, is had gap between pallet, is treated austenitizing and isothermal
The flank of tooth energy thermally equivalent of the spiral bevel gear casting of quenching and cooling, so, reduce or eliminate deflection.
Brief description of the drawings
Fig. 1 is schematic perspective view of the present utility model.
Embodiment
As shown in figure 1, the present embodiment is made up of pallet 1 and limitation vertical rod 2, limitation vertical rod 2 is fixed in pallet 1
The heart, the upper surface of pallet 1 is evenly distributed with several projections 3.Treat the spiral bevel gear casting of austenitizing and isothermal hardening with center
Axis hole is overlayed on pallet 1 through limitation vertical rod 2, treats the flank of tooth court of austenitizing and the spiral bevel gear casting of isothermal hardening
Under.Because the nethermost spiral bevel gear casting for treating austenitizing and isothermal hardening is supported by several projections 3, with pallet
There is gap between 1, flank of tooth energy thermally equivalent and the cooling of austenitizing and the spiral bevel gear casting of isothermal hardening, institute is treated
To reduce or eliminate deflection.
