Detailed description of the invention
As shown in Figure 1-2, the one described in the utility model embodiment, without the thin ancient piece of jade, round, flat and with a hole in its centre slack tank of external mold expander, comprising: line shaft 1, the dynamic cam 2 of described line shaft 1 outer cover; Transmission bracket 5 middle parts are separately installed with bottom the drive 4 that matches with described power cam 2 and rotate, and the curved protrusion of described power cam 2 is between two described drives 4; Push rod 6 is arranged on described transmission bracket 5 upper ends; Transition axis 7 assigns into described push rod 6 tops, and base 9 is arranged on described push rod 6 tops, and guide pad 8 is installed on described base, and the expander die 10 of multiple same structures is arranged on described base 9 tops; Described expander die 10 upper and lower end inner sides are equipped with ring spring 11.Described transition axis 7 is fixedly connected with by connector with described push rod 6, described push rod 6 lower ends assign in the groove of described transmission bracket 5 upper ends and fix by key, power transmission shaft 3 is fixedly connected with described transmission bracket 5 by bolt, and the mode that described drive 4 is matched in clearance is sleeved on described power transmission shaft 3.First, the moulding of this thin ancient piece of jade, round, flat and with a hole in its centre slack tank, without external mold, makes to become very convenient in the time of moulding, owing to there is no external mold, make the demoulding very convenient simultaneously, adopt this device, as long as change the profile of expander die, nearly all thin ancient piece of jade, round, flat and with a hole in its centre slack tank profile can moulding, and secondly, the shaping speed of thin ancient piece of jade, round, flat and with a hole in its centre slack tank is fast, by rational drive path, make decrease machining cost, stable drive, reducing noise.
As shown in Figure 3, described transition axis 7 is taper.
As shown in Figure 4, described expander die 10 quantity are even number.
When concrete use: line shaft drives power cam to make the circular motion on horizontal plane, power cam passes through power transmission shaft, drive and transmission bracket drive push rod to move up and down, transition axis also moves up and down simultaneously, the circular cone top of transition axis upper end forces expander die motion, and its movement locus is for to spread and contractile motion along the center of circle.The route of this power drive mechanism transmission is simple, and motion steadily, reliable.Now the course of work to expander and principle are introduced, in the time that transition axis up pushes up, the circular cone addendum cone face of transition axis upper end acts on expander die, expander die is by the effect of guide pad, the elastic force that overcomes ring spring outwards moves along the direction of diameter, the outer surface of expander die contacts and moulding with thin ancient piece of jade, round, flat and with a hole in its centre slack tank to be processed, expander die has ten compositions of same structure, makes the thin ancient piece of jade, round, flat and with a hole in its centre slack tank outer surface transition after moulding round and smooth.In the time that transition axis down moves, by the restoring force of ring spring, force slack tank mould along the direction of diameter, to center of circle contraction, the thin ancient piece of jade, round, flat and with a hole in its centre slack tank after moulding takes out by other device, and a hole enlargement process completes.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
