Have employed the principle of the present invention of technique scheme, design philosophy and beneficial effect is:
During the present invention uses, handle and the caliper of pliers made by the stainless steel of soft, jaw is made with the stainless steel of higher hardness, caliper, jaw size differs, to facilitate seam crossing solder flux being coated in both, by caliper, jaw is first screwed or first both is clamped with the blue mother of folder, again the solder flux of similar fusing point is coated in both seam crossings, caliper, jaw size differs, to facilitate the coating of solder flux at seam crossing, the workpiece this being coated with solder flux is put into vacuum drying oven again or is with the crawler furnace of gas shield to quench and solder melts implementation welding while quenching, it is an entirety that binding clip is connected with jaw, last round binding clip, finished product is made after excess stock excises by jaw Linear cut or grinding machine, such jaw is the stainless steel that hardness is higher, handle and caliper are the stainless steel of middle soft, solve jaw blackout very well, the problem of getting rusty.
It is emphasized that core innovative point of the present invention is not only selection and the replacement of jaw material especially, but be that quenching is carried out with welding simultaneously, specifically, because low or middle soft stainless steel is different with the stainless steel hardening heat of high rigidity, general field technical staff can not consider that this bi-material quenches simultaneously, especially with PH stainless steels such as 17-4, as caliper material, (such material is generally after quench hot " also known as admittedly melting ", the ideal effect of this material just will can be reached) through complicated 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 the present invention mainly considers the hardening heat of jaw material, ensure that jaw hardness reaches designing requirement.In addition because soldering processes are also more abstruse subjects, due to the difference of soldering oven (vacuum drying oven and gas shield stove), use solder flux also different, this needs to select suitable solder flux, and the welding temperature of solder flux is higher than 800 degree.
If first quench, then weld, the welding temperature of such solder flux generally lower (less than 500 degree), otherwise will anneal by original quenched materials; And with the solder flux of lower temperature (less than 500 degree), in general adhesive strength is lower, and easy Off falls, and existing a kind of technique of welding carbide alloy just easily turns around; And the general rustless property of this type of solder flux is poor, easily rust or blackout.
If first weld, then quench, 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 weld or butt-joint, because these welding can only in surface soldered, and most of pliers is held jaw (or edge of a knife) and finally all can be machined to central core, so the pliers of like this 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 the present invention simultaneously, first it must consider the temperature province of quenching jaw high-hardness stainless steel, the requirement that can meet handle and caliper after middle soft stainless steel quenches under this hardening heat to be taken into account simultaneously, choose the suitable solder flux being applicable to stove and temperature in this hardened area simultaneously; Hardening heat is a little more than solder melts temperature, make both to meet quenching requirement, solder melts is made again to reach the object of welding, compare above-mentioned several welding procedure, the present invention's welding of quenching is carried out simultaneously, and welding can be made more convenient, cost is lower, simultaneously owing to using high temperature fluxes, make soldering strength stronger, better effects if.
Again furtherly, caducous problem is held in order to solve jaw better, first binding clip and jaw CARBURIZING FURNACE FOR STAINLESS FASTENER are linked together, binding clip is coated in again with solder flux, the seam crossing of jaw and the head surrounding of screw, the workpiece this being coated with solder flux is put into the crawler furnace quenching of vacuum drying oven or band gas shield and welds simultaneously, make two kinds of stainless steel material shapes linking together in aggregates, finally with Linear cut or grinding machine by binding clip, binding clip unnecessary material excision to make finished product, such jaw is the stainless steel that hardness is higher, handle and binding clip are the stainless steel of middle soft, in succession with the screw of solder flux and band solder flux between caliper and jaw simultaneously, reliably highly stable, solve the problem that comes off of jaw well.
The processing that structure of the present invention and processing method are not only applicable to medical calm, cut, is also equally applicable to other industry, kind pincers, the processing of cutting.
