Abstract
The utility model discloses a hanging disc for crankshaft nitrogen treatment, which comprises an upper floral disc, a lower floral disc and a lifting hook, wherein the upper floral disc is connected with the lower floral disc through upright posts; the lifting hook penetrates through the upper floral disc and is connected with the lower floral disc. The utility model provides the hanging disc for crankshaft nitrogen treatment, which is simple in structure and convenient to operate, can enable a crankshaft to be in full contact with cooling solvent and greatly improve the cooling efficiency.
Description
Technical field
The utility model relates to a kind of crankshaft nitriding processing and coils with extension.
Background technology
Gas nitriding technique is that workpiece is placed in nitriding furnace, utilizes NH3 gas directly to be input in nitriding furnace to make NH3 gas to be decomposed into (N) gas of atomic condition and carries out the nitriding processing with (H) gas.It makes product surface produce wear-resisting, corrosion-resistant compound layer is main purpose.Crankshaft nitriding not only will be put into bent axle the nitriding furnace nitrogenize, and need to be undertaken cooling by the bent axle after nitrogenize.Currently used bent axle cooling of tool exists bent axle fully not contact with solvent when cooling, the problem that cooling efficiency is low.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of crankshaft nitriding to process and uses the extension dish, and it is simple in structure, easy to operate, can make bent axle fully contact with cooling solvent, has greatly improved cooling efficiency.
The utility model is the purpose that reaches above-mentioned, and the utility model adopts following technical scheme:
A kind of crankshaft nitriding is processed and is used the extension dish, comprises floral disc, lower floral disc and hangs ditch, and wherein said upper floral disc is connected with lower floral disc by column; The described ditch that hangs runs through floral disc and is connected with lower floral disc.
Offer respectively permeable hole on described upper floral disc and lower floral disc.
Offer respectively permeable groove on described upper floral disc and lower floral disc.
The beneficial effects of the utility model are: the utility model provides a kind of crankshaft nitriding to process and uses the extension dish, and it is simple in structure, easy to operate, can make bent axle fully contact with cooling solvent, has greatly improved cooling efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of crankshaft nitriding processing and uses the extension dish, comprises floral disc 1, lower floral disc 2 and hangs ditch 3, and wherein said upper floral disc 1 is connected with lower floral disc 2 by column 6; The described ditch 3 that hangs runs through floral disc 1 and is connected with lower floral disc 2.Offer respectively permeable hole 4 on described upper floral disc 1 and lower floral disc 2.Offer respectively permeable groove 5 on described upper floral disc 1 and lower floral disc 2.
The described a kind of crankshaft nitriding of the present embodiment is processed with the extension dish in use, bent axle can be placed between upper floral disc 1 and lower floral disc 2, because upper floral disc 1 and lower floral disc 2 offer respectively permeable hole 4 and permeable groove 5, thereby can make bent axle and cooling solvent fully contact, greatly improve cooling efficiency.
The described a kind of crankshaft nitriding of the present embodiment is processed and is used the extension dish, and it is simple in structure, easy to operate, can make bent axle fully contact with cooling solvent, has greatly improved cooling efficiency.
