厌氧胶是一种新型胶粘剂,它与环氧树脂胶粘剂区别在于:厌氧胶在空气中呈液态,不会凝固,而当注入(或渗入)金属接缝,与空气隔绝时,在常温下即能自行固化;单组分,无需配方和加热即能使用,操作和使用十分方便;并具有粘接强度高,密封性、浸渗性和吸振性好,粘接力大,仍可拆下等特点,用于夹具零件的粘接,能提高夹具的精度,简化结构和工艺,节约材料,延长夹具的使用寿命,具有较大的经济效益。我厂在夹具上推广应用厌氧胶粘接工艺(胶粘剂均为ZY800型系列厌氧胶),经六年来的试验和生产验证,技术经济效果很好。现将应用十一例介绍如下: 1.加工箱体类工件的镗模如图1所示。前支架镗套孔d_1对于后支架镗套孔d的同轴度允差φt不易控制。如采用前后支架分别
Anaerobic adhesive is a new type of adhesive, which is different from the epoxy adhesive is: anaerobic adhesive in the air liquid, will not solidify, and when injected (or infiltration) metal seams, isolated from the air at room temperature That can be self-curing; one-component, without prescription and heating that can be used, the operation and use of very convenient; and has high bonding strength, sealing, impregnation and vibration absorption, adhesion, can still be removed And other characteristics for the fixture parts bonding, can improve the accuracy of fixture, simplify the structure and process, save material, extend the service life of the fixture, with greater economic benefits. I plant in the fixture on the promotion of anaerobic adhesive bonding process (adhesives are ZY800 series anaerobic adhesive), after six years of testing and production verification, technical and economic good. The eleven examples will now be introduced as follows: 1. Processing box type workpiece boring mold shown in Figure 1. Front bracket bore hole d_1 for the rear bracket bore hole d coaxial degree tolerance φt difficult to control. Such as the use of before and after stent
