Abstract
The invention provides an external-die-free thin-walled empty-can expanding device which comprises a power shaft, a power cam, a transmission shaft, a transmission wheel, a transmission bracket, a push rod, a transition shaft, an expanding die, a guide block and an annular spring. The power shaft drives the power cam to move circumferentially on a horizontal plane, the power cam drives the push rod to move vertically through the transmission shaft, the transmission shaft and the transmission bracket, the transition shaft moves vertically at the same time, a circular cone top at the upper end of the transition shaft forces the expanding die to move with a motion trail performing diffusion or contraction motions along a center, the circular cone top at the upper end of the transition shaft acts on the expanding die when the transition shaft jacks upwards, under the action of the guide block, and the outer surface of the expanding die contacts with a to-be-processed thin-walled empty can and is shaped; when the circular cone top at the upper end of the transition shaft moves downwards, the expanding die is restored through restoring force of the annular spring. The external-die-free thin-walled empty-can expanding device is free of external dies, high in speed, reasonable in transmission results and compact.

Summary of the invention
Outside the deficiency existing in the problems referred to above, the invention provides a kind ofly without the thin ancient piece of jade, round, flat and with a hole in its centre slack tank of external mold expander, without external mold, speed is fast, and the result of transmission is more reasonable, compactness.
In order to address the above problem, the invention provides a kind of without the thin ancient piece of jade, round, flat and with a hole in its centre slack tank of external mold expander, comprise line shaft (1), power cam (2), power transmission shaft (3), drive (4), transmission bracket (5), push rod (6), transition axis (7), expander die (8), guide pad (9) and ring spring (10), wherein, described 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, its movement locus is for to spread and contractile motion along the center of circle, when transition axis up pushes up, the circular cone top of transition axis upper end acts on expander die, expander die is by the effect of guide pad, 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, when down move in circular cone top, the upper end of transition axis, restoring force by ring spring resets, force slack tank mould to shrink along the direction of guide pad.
Further, described expander die is comprised of ten 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.
Further, described transition axis is taper.
Further, by described guide pad, realize the control to transition axis.
Further, described expander die is consistent with the profile of tank body.
Compared with prior art, the present invention has the following advantages:
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 when moulding, simultaneously owing to there is no external mold, makes the demoulding very convenient, adopts 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.
Secondly, the shaping speed of thin ancient piece of jade, round, flat and with a hole in its centre slack tank is fast.
Finally, by rational drive path, make decrease machining cost, stable drive, reducing noise.
Accompanying drawing explanation
Fig. 1 is of the present invention without the thin ancient piece of jade, round, flat and with a hole in its centre slack tank of external mold expander structural representation.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and example, the present invention is described in further detail.But example is not as a limitation of the invention.
As shown in Figure 1, the invention provides a kind of without the thin ancient piece of jade, round, flat and with a hole in its centre slack tank of external mold expander, comprise line shaft (1), power cam (2), power transmission shaft (3), drive (4), transmission bracket (5), push rod (6), transition axis (7), expander die (8), guide pad (9) and ring spring (10), wherein, described 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, its movement locus is for to spread and contractile motion along the center of circle, when transition axis up pushes up, the circular cone top of transition axis upper end acts on expander die, expander die is by the effect of guide pad, 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, when down move in circular cone top, the upper end of transition axis, restoring force by ring spring resets, force slack tank mould to shrink along the direction of guide pad.
Preferably, described expander die is comprised of ten 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.
Preferably, described transition axis is taper.
Preferably, by described guide pad, realize the control to transition axis.
Preferably, described expander die is consistent with the profile of tank body.
Below introduce in detail transmission mechanism and principle without the thin ancient piece of jade, round, flat and with a hole in its centre slack tank of external mold expander, (referring to without the thin ancient piece of jade, round, flat and with a hole in its centre slack tank of external mold expander driver composition), line shaft (not marking in figure) 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 of expander and principle are introduced, when transition axis up pushes up, the circular cone top 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, ten compositions of expander die and same structure, make 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.When down move in circular cone top, the upper end of transition axis, the restoring force by ring spring resets, and forces slack tank mould to shrink along the direction of guide pad, and 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.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
