Abstract
The utility model discloses a salt-bath furnace for surface colouration machining for piston ring spiral bracing springs and relates to the technical field of machining for piston ring spiral bracing springs. The salt-bath furnace disclosed by the utility model comprises a rectangular iron plate box provided with an open hole on the upper part, wherein a cubic stainless steel groove provided with an open hole on the upper part is arranged in the rectangular iron plate box, a heat-insulating layer is arranged between the rectangular iron plate box and the cubic stainless steel groove, and an electric heating bar is inserted in the heat-insulating layer in a penetrating manner. By virtue of the salt-bath furnace disclosed by the utility model, hot melting for sodium nitrite due to a high temperature can be effectively guaranteed, and the temperature uniformity of the sodium nitrite liquid can be realized, so as to guarantee uniform colouration and no chromatic aberration in the handled work, and achieve the purposes of high efficiency and energy conservation.
Description
Technical field
The utility model relates to the processing technique field of piston ring helical supporting spring.
Background technology
In the processing of piston ring helical supporting spring, the client's proposition that has needs the requirement of sorrel or filemot piston ring helical supporting spring, for this reason; Existing manufacturing enterprise great majority adopt pit furnace, and perhaps other devices of heating carry out heat treated with piston ring helical supporting spring; Reaching painted purpose, but in these heating units, air can not produce complete convection current; Heat energy only depends on conduction or thermal radiation, and temperature is seriously inhomogeneous, when piston ring helical supporting spring is put into heating unit; The central point piston ring helical supporting spring is with very serious near the piston ring helical supporting spring aberration of furnace wall, and the product of producing is difficult to reach requirement of client, and; Piston ring helical supporting spring is prone to produce reaction with oxygen at the hot conditions lower surface, the piston ring helical supporting spring surface is produced oxidation takes place, and gets rusty easily; Also exist production efficiency low in addition, the phenomenon that tank liquor is difficult in maintenance.
In order to change the defective of prior art, the contriver proposes a kind ofly to adopt liquid high-temperature sub SODIUMNITRATE that piston ring helical supporting spring is carried out the working method of immersion treatment, and it is even to have a piston ring helical supporting spring surface chromaticness, the characteristics that the percentage of A-class goods is high.
Summary of the invention
The utility model purpose is to be the supporting piston ring helical supporting spring surface colour refined salt liquid furnace of soaking technology.
The utility model comprises that the top is provided with open rectangle iron plate case; Be provided with open square stainless steel groove above in said rectangle iron plate case, being provided with; Between said rectangle iron plate case and square stainless steel groove, thermal insulation layer is set, in thermal insulation layer, is interting electrically heated rod.
Earlier Sodium Nitrite is devoted in the square stainless steel groove,, make the electrically heated rod heating, make temperature conduct to square stainless steel groove equably, melt to reach the Sodium Nitrite elevated temperature heat through thermal insulation layer with the electrically heated rod energising.After certain hour insulation, can make the Sodium Nitrite in the square stainless steel groove reach uniform high temperature, and then piston ring helical supporting spring is immersed Sodium Nitrite liquid carry out surface colour and handle.
The utility model can effectively ensure not only Yin Gaowen and heat is melted of Sodium Nitrite, also can realize the temperature homogeneity of Sodium Nitrite liquid, with work uniform coloring and the no color differnece that guarantee is processed, reaches efficient, purpose of energy saving.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model is provided with the top and is provided with open rectangle iron plate case 1; Be provided with open square stainless steel groove 2 above in rectangle iron plate case 1, being provided with, between rectangle iron plate case 1 and square stainless steel groove 2, thermal insulation layer 3 be set, in thermal insulation layer 3, interting electrically heated rod 4.
