Have employed principle of the present utility model, the design philosophy of technique scheme and provide the benefit that:
nullIn this utility model, handle and the caliper of pliers made by the rustless steel of soft，Jaw is made with the rustless steel of higher hardness，Caliper、Jaw size differs，To facilitate the seam crossing that solder flux is coated in both，By caliper、Jaw is first screwed or first blue female by both clampings with folder，The solder flux of similar fusing point is coated in both seam crossings again，Caliper、Jaw size differs，To facilitate solder flux in the coating of seam crossing，This is coated with the workpiece of solder flux place in the crawler furnace of vacuum drying oven or band gas shield quenching and while quenching solder melts carry out welding，Binding clip and jaw is made to be connected as one overall，Last round binding clip、The cutting of jaw line or grinding machine make finished product after being excised by excess stock，So jaw is the rustless steel that hardness is higher，Handle and the rustless steel that caliper is middle soft，Solve jaw blackout very well、The problem got rusty.
It is emphasized that core innovative point of the present utility model is not only that selection and the replacement of jaw material especially, but be that quenching is carried out with welding simultaneously；Specifically, owing to low or middle soft rustless steel is different with the rustless steel hardening heat of high rigidity, general field technical staff does not takes into account that both materials quench simultaneously, especially with PH stainless steels such as 17-4, as caliper material, (such material is typically after high temperature quenching " also known as admittedly melting ", the ideal effect of this material is can be only achieved) through complexity tempering " also known as timeliness ", because using such material as handle and binding clip, only use partial properties (the part hardness of this material, intensity and rustless property), the requirement of handle and caliper can be met.
And this utility model is mainly in view of the hardening heat of jaw material, it is ensured that jaw hardness reaches to design requirement.Also being a subject additionally, due to soldering processes, due to the difference of soldering oven (vacuum drying oven and gas shield stove), use solder flux the most different, this needs to select suitable solder flux, and the welding temperature of solder flux is higher than 800 degree.
If first quenching, then welding, the welding temperature of such solder flux typically relatively low (less than 500 degree), the most original quenched materials will be annealed；And solder flux in general adhesive strength with lower temperature (less than 500 degree) is relatively low, easily comes off, existing a kind of technique welding hard alloy the most easily turns around；And the general rustless property of this type of solder flux is poor, easily rust or blackout.
If first welding, further quenching, welding was lost efficacy at once；Namely solder flux can lose efficacy in quenching.
If first by the stainless steel material of two kinds of different hardness sub-arc-welding or laser welding or butt-joint, owing to these welding can only be in surface soldered, and major part pliers is held jaw (or edge of a knife) and finally all can be machined to central core, so the pliers of so welding all can seam defect, have a strong impact on attractive in appearance and intensity.
In sum, the stainless steel material of two kinds of different hardness is carried out quenching, welding procedure by this utility model simultaneously, first it must consider the temperature province of quenching jaw high-hardness stainless steel, to take into account the requirement that can meet handle and caliper after middle soft rustless steel quenches under this hardening heat simultaneously, choose the solder flux being suitably suitable for stove and temperature in this hardened area simultaneously；Hardening heat is slightly above solder melts temperature, make both to meet quenching requirement, solder melts is made again to reach the purpose of welding, comparing more above-mentioned several welding procedure, this utility model quenching welding is carried out simultaneously, and welding can be made more convenient, cost is lower, simultaneously because use high temperature fluxes, making soldering strength higher, effect is more preferable.
Further say, caducous problem is held in order to preferably solve jaw, first binding clip is linked together with jaw CARBURIZING FURNACE FOR STAINLESS FASTENER, it is coated in binding clip again with solder flux, the seam crossing of jaw and the head surrounding of screw, the workpiece that this has been coated with solder flux is put into the crawler furnace quenching of vacuum drying oven or band gas shield and welds simultaneously, make the two kinds of stainless steel material shapes linked together integral, finally cut with line or grinding machine is by binding clip, the unnecessary material of binding clip excises to make finished product, so jaw is the rustless steel that hardness is higher, handle and the rustless steel that binding clip is middle soft, in succession with the screw of solder flux and band solder flux between caliper and jaw simultaneously, highly stable reliably, solve the problem that comes off of jaw well.
The processing that structure of the present utility model and processing method are applicable not only to medical calm, cut, is also equally applicable to other industry, kind pincers, the processing cut.
