Description
Technical field
The present invention relates to a kind of hot melt processing technology, especially a kind of hot melt cutter head is specifically a kind of that set can be achieved
The self- recoverage shape memory alloy heat of material processing melts cutter head.
Background technique
It is well known that metal, ceramics, polymer are the three classes typical materials in engineering.Wherein, polymer is because of its wearability
The good, overall merits such as light weight, resistance to corrosion are strong and be used widely.Polymer product mostly using molding, pultrusion at
Type, however above-mentioned method can only form simple structure, it is essential for small, labyrinth also to need at following process
Reason.Currently, in the market all using hot melt knife processable polymer product, but existing hot melt cutter head can only realize polymer material
Cutting and surface processing.Also immature for the three-dimension process technology of polymer product, existing greatest problem is exactly nothing
Method realizes fracture.
It consults pertinent literature regarding to the issue above and patent is learnt, one kind is exempted to remove plastic foam slotting machine for thermal insulating board,
Cutter is heated as more metallic sheets composition, melts waste material in slot by heating sheet metal.Although solid may be implemented in the cutter head
Processing, but there are still very big defects.On the one hand, which does not use thermal cutting fracture, falls slot using high temperature melting
Interior excess stock can generate a large amount of pernicious gases in this way；On the other hand, the waste material of processing has the bad phenomenon of sintering cutter, causes
Keep cutter head loss serious, or even having can be by the possibility of breaks down.
By the retrieval to domestic and international pertinent literature, not yet find that one kind can safe and efficient realization polymer material at present
The hot melt cutter head of three-dimension process.
Summary of the invention
The purpose of the present invention is for there has been no a kind of hot melt cutter heads of achievable polymer three-dimension process currently on the market
Problem, the self- recoverage shape memory alloy heat for designing a kind of achievable overlaying processing melt cutter head.
The technical scheme is that
A kind of molten cutter head of the self- recoverage shape memory alloy heat of achievable overlaying processing, it is characterised in that: the hot melt cutter head is main
It is made of flexible blade 1 and two sides blade 2, flexible blade 1 forms rectangular recess structure, bendable tulwar with two sides blade 2
1 one end of piece is equipped with preset clearance at the blade cutter head of two sides, be equipped at the knife tail 3 of two sides blade 2 for heating device phase
The connecting rod 5 connected and the reinforcing rod 6 for reinforcing cutter head integral strength.
The cutter head is handled by micro-impact briquetting, and using average tempering, and tempering temperature is at 450-550 DEG C.
The material of the cutter head is two-way memory alloy TiNiB, and the content of B is 0.03%-0.05%.
The device for heat treating can provide 5-24V adjustable voltage.
The flexible blade 1 can realize bending by " memory training " at high temperature, and when low temperature can restore original sample, remaining
Part then still keeps original shape at high temperature.
The length by length in the gap that the flexible blade is reserved at the blade of two sides is to need to process on polymer pipeline
1.5 times of groove depth, width can be 0.025-0.05mm.
The connecting rod 5 is a bucking ladder.
On described 2 two medial surfaces of blade and/or bottom surface is equipped with the reinforcing rib for preventing deformation, and reinforcing rib can be right for one
Linea angulata shape diagonal bar or several parallel muscle or right-angled intersection muscle.
Beneficial effects of the present invention:
(1) hot melt cutter head of the present invention, by regulating and controlling temperature, be adjusted the curved blades with round trip memory bending and
It replys, creatively realizes fracture in overlaying processing, provide a kind of new-type heat-melting overlaying processing for polymer solid forming
Tool.
(2) hot melt cutter head of the present invention, has many advantages, such as high in machining efficiency, easy making process.
(3) hot melt cutter head of the present invention is applicable to various hot-working occasions, has stronger engineering adaptability.
Marmem is that one kind can perceive environmental factor variation (heat, electricity, light, magnetic etc.) and generate shape and restore to ring
The intellectual material answered, and its shape is restored to respond and can be activated by clearance-type during entire restore, in addition each
Response terminate when its shape can be kept again, therefore by this material intelligent response and response holding characteristic, it can be achieved that
Heating blade, there is temperature to drive intelligent controllable, automatic chip breaking ability.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but this cannot be used for limit of the invention
System, those skilled in the art's basic thought according to the present invention can make various modifications or improvements, but without departing from this
The basic thought of invention, is all within the scope of the present invention.
As shown in Figs. 1-3.
A kind of molten cutter head of the self- recoverage shape memory alloy heat of achievable overlaying processing, the hot melt cutter head is mainly by flexible
Blade 1 and two sides blade 2 form, and the end profile of cutter head is a rectangular recess (shape is inverted U-shaped), as shown in Figure 1.It can
Curved blades 1 and two sides blade 2 form rectangular recess structure, and flexible 1 one end of blade is equipped at two sides blade (cutter head)
Preset clearance 4, gap length L are 1.5 times of groove depth, and width B can be 0.025-0.05mm, are equipped at the knife tail 3 of two sides blade 2
Connecting rod 5 for being connected with heating device and the reinforcing rod 6 for reinforcing cutter head integral strength, as shown in Figure 2.The knife
Head be by micro-impact briquetting, and use average tempering, tempering temperature is at 450-550 DEG C.The material of the cutter head is round trip note
Recall alloy TiNiB, the content of B is 0.03%-0.05%.Device for heat treating can provide 5-24V voltage.Flexible blade 1 is in high temperature
When can realize bending, when low temperature, can reply as former state.When it is implemented, in order to improve the intensity of blade, deformation when preventing high temperature is removed
Carrying out " memory training " to flexible blade 1 makes it at high temperature and can realize restore outer as former state when bending, low temperature, to blade
Other parts should then be designed to still keep original shape at high temperature；Meanwhile the elevated temperature strength in order to guarantee blade, it prevents from becoming
Shape can also be equipped with the reinforcing rib (not shown) for preventing deformation on 2 two opposite medial surfaces of blade and/or on bottom surface,
Reinforcing rib can be a diagonal linear diagonal bar or several parallel muscle or right-angled intersection muscle.
The processing object of the present embodiment is polymer petroleum pipeline side keyway.Its application method is as shown in figure 3, first will be hot
Molten cutter head is inserted into heating device, and adjusts voltage swing, so that tool temperature is between 140-200 DEG C, flexible blade 1 at this time
It is not bent；Secondly, hot melt cutter head is slowly inserted into polymer pipe end face to required depth after positioning；Then heating device electricity is adjusted
Pressure, at this point, flexible blade is bent downwardly, completes fracture process so that blade temperature rises to 250 DEG C or so；It is last to be curved
When tulwar piece is no longer bent, cutter head is slowly extracted out, take out cut waste material, and heating device is adjusted to low-grade location, make to be bent
Blade is cooling, restores as former state.
Part that the present invention does not relate to is the same as those in the prior art or can be implemented by using the prior art.
