Make fixed turn round around articulated shaft clockwise movement.
Existing simple joint bone forceps binding clip can be bent, and improve its versatility, and tightness is high.
As an improvement, the pincers with least one of binding clip of chromium carbide reinforced aluminum matrix composites being made.Carbonization
Chromium reinforced aluminum matrix composites preparation method is as follows, step 1：By carbon black, electrolytic chromium powder and aluminium powder according to weight（1-2）:5：
100 uniformly mixing；
Step 2：Material after step 1 is gone out to use hot-forming method, briquet is made.
Step 3：With heating rate's briquet of 10 DEG C -50 DEG C/min, 1400 DEG C -1700 DEG C are heated to, carbon black and chromium
Powder reaction generation chromium carbide enhancing phase；
Step 4：Above-mentioned element is subjected to enhancing element homogenization heat treatment；
Step 5：Composite material after above-mentioned processing is subjected to hot extrusion；
Step 6：Hot rolling treatment is carried out more than recrystallization temperature；
Step 7：Alloy after step 6 is subjected to solution treatment.
Wherein carbon black and electrolytic chromium powder can use common raw material, its scale effect to enhancing phase in step 1
Particle diameter, more tiny in order to allow to reach, the mass ratio of carbon black and electrolytic chromium powder is（1-2）:5.And the particle diameter for strengthening phase is big
The small and uniformity coefficient of base phase can add control by adjusting heating-up temperature, the heating-up temperature selection 1400 in the present invention
DEG C -1700 DEG C, and the size of the rate of heat addition determines the speed of preheating.
As an improvement, the particle diameter of the electrolytic chromium powder is 400 mesh.
As an improvement, the aluminium powder is superfine aluminium power, the precision of aluminium powder is 16 ~ 30 μm.
As an improvement, the rate of heat addition of the step 3 kind is 20 DEG C/min.
As an improvement, the heat treatment temperature of the step four is 600 DEG C -800 DEG C, heat treatment time is 20 min-
100min, heat treatment carry out under an inert gas.
As an improvement, the hot extrusion ratio of the step 5 is 20:1-8:Between 1, extrusion temperature is controlled at 500 DEG C -700
℃。
As an improvement, the heating-up temperature of the step 3 is 1500 DEG C -1600 DEG C, and then the size controlling of chromium carbide is existed
Preferably horizontal, further preferably heating-up temperature is 1550 DEG C.
As an improvement, it is 25%-30% that carbon black, which accounts for enhancing phase raw material weight, in the step one, in this preferable case
Under, the chromium carbide obtained in the original location among generating process is more fine and close, reaches Nano grade, and fully dispersed can arrive base
Among body material.
Composite material disclosed by the invention is applied in aluminium alloy 3D printing field, enables to the properties of product printed
Reach the effect of forging, and existing is typically the performance for not reaching forging.
Chromium carbide enhancing mutually can reach Nano grade, the simple joint bone of preparation in aluminum matrix composite disclosed by the invention
Clamp light and portable, this nano ceramics aluminium alloy is light-weight, and with high rigidity, high intensity, antifatigue, low bulk, high-damping,
The features such as high temperature resistant, compared to titanium alloy and high temperature alloy, can significantly increase the dimensional stability of simple joint bone forceps.
