Description
Technical field
The utility model relates to tubing process equipment field, relates in particular to a kind of spiral head.
Background technology
The naturally cooling or oil cooling of the cooling general employing of spiral head. When producing the tubing of special formulation and squeezingWhen output is larger, plug and spirochetal temperature rise, easily cause inwall premature aging. Use natureCooling, heat exchange deficiency, cooling velocity is too slow. Use oil cooling, oil circuit is for a long time 160～230 DEG C of temperature worksDo, oil decomposition makes the easy coking obstruction of oil circuit, or oil sealing leakage of oil, the oil temperature machine that finally makes temperature control useCisco unity malfunction, delays production; And profit heat exchange, water wasting expense electricity. Oil cooling cooling is fast, but meetingCause temperature big ups and downs.
Utility model content
The purpose of this utility model is to provide a kind of spiral head, solves the problem of existing spiral head heat radiation,So object has better heat dispersion in the temperature of head inside, for processing temperature being had to higher wantingThe tubing of asking.
For addressing the above problem, the utility model embodiment provides a kind of spiral head, comprise head cover andConveyor screw, described conveyor screw is sheathed in described head cover, and described conveyor screw is provided with some to for windCold air channel, every pair of described air channel comprises air inlet duct and exhaust passage, described air inlet duct comprises air inlet, instituteState exhaust passage and comprise gas outlet, described air inlet and gas outlet are located at conveyor screw surface and are exposed to head coverOutward.
Optionally, some air channel is uniformly distributed along conveyor screw circumferencial direction.
Optionally, described air inlet duct and described exhaust passage distribute along Central Symmetry, adjacent two air inlet ductsInterval is equal, and the interval of adjacent two exhaust passages equates, and air inlet duct interval equates with interval, exhaust passage.
Optionally, some to air channel along helicoid shaft to stacked setting.
Optionally, in the middle of air channel, be provided with multiple-way valve, described multiple-way valve connects all air inlet ducts and all air-outRoad.
Optionally, the quantity in described air channel is three pairs.
The utility model spiral head adopts air cooling way to dispel the heat, and in contrast to the cooling and oil cooling side of natureFormula, cooling rate is moderate, can not cause the problem that temperature big ups and downs or cooling velocity are slow.
Compared with prior art, the technical program has the following advantages:
1, conveyor screw internal cooling medium is air, does not have evaporating, emitting, dripping or leaking of liquid or gas situation, can not wear and tear in inside, needsThe part of safeguarding is all in spiral head outside, and maintaining is convenient;
2, the specific heat of air is large, cooling even, can pass through to regulate vacuum (air-breathing speed) and intake air temperature, rightThe temperature of die head regulates;
3, cooling needed energy is less.

Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, to the technical solution of the utility model carry out clear,Complete description.
As shown in Figure 1, a kind of spiral head, comprises head cover 1 and conveyor screw 2. In head cover 1, be provided withCavity, conveyor screw 2 is positioned in cavity. Conveyor screw 2 is provided with some to air channel 3, and wrap in every pair of air channel 3Draw together air inlet duct 31 and exhaust passage 32. Air channel 3 air inlets and gas outlet are located at conveyor screw 2 surfaces and are exposed toOutside head cover 1.
Spiral head of the present utility model uses air-cooled, and air inlet uses air-cooling apparatus 6 to enter air intakeRow is cooling, and gas outlet is used vavuum pump 5 air-breathing, thereby makes air in the interior circulation of conveyor screw 2, makes headInner temperature has better heat dispersion. Therefore, this screw machine head is more applicable for processing temperatureThe tubing having higher requirements.
With regard to the set-up mode in air channel 3, there is various embodiments, explain for convenience, below realExecute routine air channel 3 quantity and be three pairs.
Embodiment mono-
As shown in Fig. 2 to 3, three pairs of air channels 3 are uniformly distributed along conveyor screw 2 circumferencial directions. Every pair of air channel 3Air inlet duct 31 and exhaust passage 32 distribute along Central Symmetry, the air inlet duct of now conducting 31 and exhaust passage 32Be 180 ° of settings, place along the diametric(al) of conveyor screw 2 circumference in air channel 3. Adjacent two air inlet ducts 31Interval equate with the interval of adjacent air inlet duct 31 and exhaust passage 32, angle is 60 °. As Fig. 3 to 4Shown in, the three pairs of air channels 3 along conveyor screw 2 axially stacked (B place in figure) arrange, i.e. three pairs of air channels 3Mid portion is not in same level, and now, the length in every pair of air channel 3 is unequal, more high-rise windRoad 3 length are longer.
The advantage of the present embodiment is, exhaust passages 32 corresponding to single air inlet duct 31, circulation of air speedHurry up.
Embodiment bis-
As shown in Fig. 2 and 5, the three pairs of air channels 3 along conveyor screw 2 circumferencial directions be uniformly distributed (divide by region,Every 120 ° arrange a pair of air channel 3). As shown in Figure 5, adjacent path is with a pair of air channel 3, every pair of air channel 3Between not mutually intersect.
The advantage of the present embodiment is that conveyor screw 2 integral heat sinks are even, can not cause local temperature too high.
Embodiment tri-
As shown in Fig. 2 and 6, three pairs of air channels 3 are uniformly distributed along conveyor screw 2 circumferencial directions. Every pair of air channel 3Air inlet duct 31 and exhaust passage 32 distribute along Central Symmetry, the air inlet duct of now conducting 31 and exhaust passage 32Be 90 ° of settings, place along the diametric(al) of conveyor screw 2 circumference in air channel 3. Adjacent two air inlet ducts 31Interval equate with the interval of adjacent air inlet duct 31 and exhaust passage 32, angle is 60 °. I.e. three pairs of air channels3 mid portion, not in same level setting, is provided with multiple-way valve in the middle of air channel 3, multiple-way valve connects instituteThere are air inlet duct 31 and all exhaust passages 32.
The advantage of the present embodiment, each air inlet all can corresponding many air outlets, when each air outlet stops upTime, can flow out by other exhaust passage 32.
