2, be that the thin-wall metal pipe (as stainless pipe) of 0.2～0.5mm is inserted respectively in each chopsticks template chamber of mould with wall thickness, and by compress the two ends actinal surface and the two sides of metal circular tube by the horizontal module of hydraulic cylinder control and vertical module;
3, utilize inlet nozzle that pressure oil is injected metal circular tube, make it to be full of;
4, the pressure that produces by the electric-controlled hydraulic pump pressurizes to metal circular tube, and pressurize was 20～30 seconds when pressure was 30～100MPa value, and making metal circular tube by hydraulic coupling is side-circle chopsticks spline structure pipe according to the mold cavity warpage;
5, utilize the pressure oil in oil outlet general side-circle structure chopsticks sample shape pipe to draw off, remove vertical module and horizontal module, chopsticks spline structure plumber part is taken out;
6, by welding manner end socket is welded at chopsticks spline structure pipe two ends, forms hollow chopsticks, behind each hollow chopsticks sanding and polishing, chopsticks body surface scribe or air brushing on calligraphy and painting pattern, make metal hollow chopsticks.
The metal hollow chopsticks former that is used to finish above moulding process and develops comprises mould and hydraulic system two-part structure, wherein, said mould be in its that form by upper die and lower die along flat to the parallel member that is provided with multiple tracks side-circle chopsticks spline structure die cavity, be provided with vertical guide pillar and the vertical mould that can move up and down along vertical guide pillar on the top of mould, sidepiece at mould is provided with horizontal guide pillar, be equipped with mould at an end of horizontal guide pillar and adjoin the fixed die that connects, the other end at horizontal guide pillar is provided with the horizontal mould that can do horizontal movement along horizontal guide pillar, is provided with the conical surface oil nozzle slotted eye that can be communicated with various accent end in the mould in fixed die and horizontal mould; The member of said hydraulic system then comprises following member: 1., hydraulic pump, 2., the precursor overflow valve that is connected work with hydraulic pump oil duct pipeline, 3., be connected four solenoid directional control valves of work and 4. with precursor overflow valve oil duct pipeline with hydraulic pump, by the control of solenoid directional control valve be used to drive vertical mould and make vertically vertical hydraulic cylinder to motion, 5., by the cross cylinder that is used for the horizontal mould horizontal movement of driving of solenoid directional control valve control and 6., the conical surface oil nozzle that injects or draw off pressure oil to fixed die and horizontal mould inner conical surface oil nozzle slotted eye that is respectively applied for by other two solenoid directional control valves control.In the course of work, behind each chopsticks template chamber of the thin-wall metal pipe being inserted mould, drive side and the two ends that vertical module and horizontal module compress metal circular tube by vertical hydraulic cylinder and cross cylinder, order about conical surface oil nozzle injection pressure oil in metal circular tube by solenoid directional control valve, make the metal circular tube side of being shaped to-circle structure by hydraulic coupling; After the moulding,, and vertical module and horizontal module are removed, taken out workpiece, finish the shaping work of chopsticks sample hollow metal tube again by conical surface oil nozzle downstream line inner fluid.
Compared with prior art; the present invention has that the material use performance is good, production efficiency is high, be convenient to advantages such as large-scale production; metal hollow chopsticks surface high conformity, light, the comfortable feel of quality of utilizing this method and apparatus to produce; help this area and progressively replace the particularly wooden chopsticks of disposable bamboo of bamboo wooden chopsticks, protect forest resources with metal matter chopsticks.
