Background technology
At present, our known die surface processing mode is mainly nitriding, carburizing and cured film deposition technique.And nitridation process is subdivided into gas nitriding, liquid nitriding, glow discharge nitriding, but gas nitriding technology exist production cycle length, nitriding speed is slow, efficiency is low, costly, to shortcomings such as material requirements are strict, additionally, there is the shortcomings such as infiltration layer work surface digital control processing thin, unrelated difficulty in liquid nitriding technique.Therefore, can not bear the biggest contact stress and high shock loading with the nitriding part of gas nitriding and liquid nitriding technique, applicable scope is narrow.
Summary of the invention
The invention aims to overcome above-mentioned technical disadvantages to provide a kind of small-sized glow ion die treatment equipment.
The present invention solves the technical scheme of technical problem employing: a kind of small-sized glow ion die treatment equipment, including tank body, electrical control cabinet and workpiece pending in being placed on tank body, described inner tank wall is provided with heat-insulation layer, described tank body is provided with low density gas ascending pipe, described tank body is also associated with vacuum pump, cathode radiant heating plate it is provided with in described tank body, described cathode radiant heating plate and pending workpiece are respectively by connecting the connection of wire lug the most corresponding with electrical control, described tank body is provided with hermatic door, described hermatic door is provided with locking button.
Being provided with cooling layer between described tank body and heat-insulation layer, this cooling layer is bosh, connects and have the cooling fan that heat in cooling water can be passed on described bosh.
The heat screen of energy heat-insulation and heat-preservation it is provided with inside described heat-insulation layer.
Present configuration is reasonable in design, easy and simple to handle, speed of production is fast, the most especially prominent when nitriding time is shorter, ion-nitriding layer organizational structure is controlled, the good toughness of ion-nitriding layer, significantly expand glow discharge nitriding range of application, the steel grade that not only ordinary gas nitridation is applied can carry out glow discharge nitriding, applies also for the workpiece of nitrocarburizing (tufftride), and very energy-conserving and environment-protective.
