Technique scheme of the present invention also can be further perfect, and as preferably, its cross section of described uncovered thin-wall construction is flute profile or U-shaped.
As preferably, the flute profile or the U-shaped of protrusion bottom being, its cross section of described uncovered thin-wall construction arranged.Also can be that two sides have stagewise flute profile or U-shaped.
As preferably, described connecting rod is a degree of lip-rounding closing structure on an empty stomach.This helps improving the intensity of whole caliper.
For helping improving the intensity and the rigidity of jaw, as preferably, described battery lead plate is flute profile with jaw inwall contact portion or U-shaped cooperates.That is the inwall of jaw and the electrode pad outside matches, and uses adhesive bond, makes it to form an integral body.
The closed treatment electricity of a kind of medical ligation speed pincers processing technique,
It is characterized in that: metal caliper processing technique approach is:
A. metal plate material blanking;
B. connecting rod flanging;
C. main body stretches;
D. jaw is cut edge;
E. heat treatment;
F. jaw grinding.
Technique scheme of the present invention also can be further perfect, as preferably, carries out shaping behind the heat treatment and handle on punch press; After the jaw grinding, carry out the processing of the anti-electric shock of incrustation processing and surface insulating barrier.After Overheating Treatment, micro-deformation might appear in jaw, and this micro-deformation can be proofreaied and correct at punch press.Incrustation one is that consideration is attractive in appearance, the 2nd, play the protective effect of surface layer.Anti-electric shock insulating barrier is handled and can be formed a layer insulating on the jaw surface, makes it to have certain anti-electric shock ability.
As preferably, described heat treatment adopts vacuum hardening, and hardness is HRC40-HRC50.More the hardness of You Huaing is HRC 45-HRC48.
As preferably, described incrustation is handled and is adopted the inferior light chromium of plating.
Therefore, beneficial effect of the present invention is: because traditional metalworking operation that prior art adopted has been abandoned in the processing of metal caliper, but adopt the metallic plate punching drawing and forming, thereby form hollow jaw and the closed connecting rod technology of empty stomach, and the one, need adopt the cumbersome manufacturing procedure of multiple lathe to become very simple prior art; The 2nd, improved labor productivity, its production efficiency improves more than 30 times; The 3rd, improved the utilization rate of material to greatest extent, saved the energy, material can be saved more than 2/3, and machining accuracy guarantees that easily steady quality greatly reduces production cost, has stopped cross infection, welcome by various big hospital and patient.
