Specific embodiment
It should be noted that the feature in embodiment and embodiment in the case where not colliding, in the invention
It can be combined with each other.
Detailed description of specific embodiments of the invention is provided below.
A kind of ductule tip machine particular manufacturing craft, as shown in Figures 1 to 4, including the shaping mould in pedestal 1 and pedestal；Institute
It states shaping mould to be made of several petal bodies 2, forms the forming cavity 3 of pyramidal structure inside shaping mould；To guarantee mold overall structure
Stability, die body between pedestal inner wall of the hole installing at maximum gap at a distance from 2-5mm, such structure arrangement can be with
Guarantee the stability of mold when tip processing to greatest extent, spacing is excessive between being unlikely to die body, avoids out existing significantly abnormal
The case where play.
The pedestal rear end is equipped with tailstock 4；The base interior is equipped with the mounting hole 5 of cone cell, is equipped with and peace inside tailstock
The corresponding inner cavity in hole is filled, and its intracavity diameter is greater than mounting hole smallest end diameter；In general, tailstock intracavity diameter is than mounting hole minimum
Diameter 5-15mm or so is held, when guaranteeing that each petal body is opened or is closed, die body tail portion will not be interfered with the inner wall of inner cavity, institute
Tailstock inner wall is stated to be equipped with for forming the positioning plate 6 limited to each die body；
Above-mentioned positioning plate can guarantee that each die body is not in offset deviation on die length direction, in general, positioning
Plate can be the cyclic structure around cavity wall in tailstock, while being formed and being limited to each die body.Each die body tail portion is not and fixed
Position plate is fixed, and in the adjustment of forming cavity size adaptation, does not influence the movement of die body, no interference happens.
The mounting portion inner wall is equipped with several demarcation plate 7, and correspondence is equipped with a die body, phase between every two demarcation plate
It is equipped with the first holder 8 for tensing this two die bodys tail portion between adjacent two die bodys, corresponds to each die body on the base and is all provided with
Having for keeping each die body is in the second holder 9 of mutual tightening state；
Each equal side of die body is equipped with travelling arm 10, and the other side is equipped with the sliding slot 11 cooperated with the travelling arm of adjacent die body；
Two adjacent die bodys are that the travelling arm of a die body is inserted into the sliding slot of another die body；
The both ends that the in vivo surface is in rotation direction are equipped with molding blade 12.Molding blade referred herein is really
It is made of the fillet between in vivo surface and its side wall, is not additional cutting edge structure, molding blade acts predominantly at this
When tip processing, it can constantly be squeezed ductule end that (under the thrust of the second holder, each die body is oriented
The active force that center is gathered, that is, for die body after by conduit active force " spreading ", the second holder can push die body to center always),
During pushing back die body reset, the curved form in actual motion track (the non-straight line straight up and down of certain point at molding blade
Movement), or even the operating mode for being similar to and rolling can be reached.In addition, shaping mould is under the drive of pedestal in rotation in addition
State (pedestal driven rotation realizes tip work production), therefore, greatly improves the quality of ductule tip processing,
Meanwhile processing efficiency also has very big promotion.
After ductule one end is pushed into the forming cavity of this mold, each die body can generate adaptive adjustment, that is, forming cavity is opened
Mouth size can be first by " swell ", and as further tip is processed, can have under the active force of the first, second holder
The trend of " tightening " forming cavity opening, such structure design ensure that and be adapted to plurality of specifications diameter ductule, versatility
It is good.
Preferably, first holder uses tension spring, which is separately fixed at corresponding side die body tail portion 13.
Second holder uses pressure spring, one end of which is fixed in the slot 14 of base internal wall, the other end inherently with die body outer surface
The jacking block 15 of cooperation；The jacking block is equipped with and the consistent groove 16 of die body outer surface radian towards the side at shaping mould center.
It should be noted that jacking block can be rubber pad, nylon cushion or copper packing, damping property is good, and can smoothly and mould
It shows consideration for and closes, guarantee the stable power that plays a role of the second holder.
The travelling arm is in arc structure, and radian is consistent with die body radian.It is mutual " tightening " or " spreading " in each die body
During, for each die body by the pulling of the first holder and the thrusting action power of the second holder, each die body institute is loaded
Lotus size and direction are consistent, and therefore, mutual spacing is also consistent substantially, per between adjacent two die body close to or far from mistake
Cheng Zhong, the smooth sliding in the sliding slot of another die body of the travelling arm of one of die body guarantee always to be in cone at each die body center
The forming cavity of shape, that is, " rolling " effect is formed to ductule tip always.
Preferably, the equal chamfered in mounting hole both ends of the pedestal.The height of the partition is less than the thickness of die body, and
Partition is not interfered with travelling arm.Cooperate between each component and stablize, partition cooperates between will not influence die body.In general, the die body
3-6 are uniformly arranged along base central, and each die body size, shape are identical.
In an alternative embodiment, adjustment mechanism, the adjustment mechanism are equipped between each die body and pedestal
Stretch out the fixed block 17 that is arranged on the outer surface of pedestal one end including die body, be removably equipped on the pedestal for fixation
The fixed connector 18 of block.Each motif position can be fixed according to processing needs.
It should be pointed out that attachment base 19 can be set on the base, connector is arranged on attachment base, specifically,
Attachment base can be the ring structure around the setting of forming cavity open outer side, that is, every a connection piece respectively corresponds on corresponding die body
Fixed block, for being connected and fixed corresponding die body.In general, connector uses complete thread screw, the company of screwing can according to need
Fitting screws in the depth of fixed block, and then the forming cavity openings of sizes for changing die body can consolidate each die body by adjusting mechanism
It is fixed, that is, to fix forming cavity shape, to meet specific processing needs.
It should be noted that can be and be installed on the chuck of lathe in application this mold progress tip production, it can also
To realize the rotation stable with moving base by corresponding driving mechanism (being such as fixed on one end of drive shaft).In tip
When production, the ductule of heating one end to be processed is gradually inserted in the forming cavity of mold cone cell, gradually forms point using die body
Head.How to be fixed as pedestal, those skilled in the art can be designed according to actual needs.It can be through bolt etc. even
Fitting, is also possible to be connected by key or the fit forms such as card slot, is not specifically limited herein, it is fixed i.e. can to consolidate installation
It can.
The invention structure is simple, and rationally, the processing of suitable for various size ductule tip can also be according to design for design
Using needs, the forming cavity of shaping mould is fixed on a certain specific shape, meets special process requirements, versatility is good, processing
It is high-efficient, quality of finished product good.
It is obvious to a person skilled in the art that the invention is not limited to the details of above-mentioned exemplary embodiment, and
And without departing substantially from the spirit or essential attributes of the invention, wound that the present invention can be realized in other specific forms
It makes.
