For example, a packet 3 is a conventional device having a tubular, aluminum tubular body of an inductor that heats the current induced by the inductors to drive the tubular body. The disadvantage of this type of device is that it uses a "large-scale approach" to heat this result to show that the heating time is extended due to the heat diffusion in the body of the (four) tube. In addition to the decrease in productivity, The result of the elongation is accompanied by a corresponding higher energy consumption and an equal ratio of the cold portion time. The device described above also has the disadvantage that it exhibits a poor efficiency relative to inductive heating. SUMMARY OF THE INVENTION It is an object of the present invention to provide a simple, low cost method and apparatus. 200906232 is used to heat tubular or core members by means of a side anthill for shaping a tubular member from a composite material.

Therefore, the invention relates to a device for heating a tubular or solid body comprising: f
一被設計用來包含零件之金屬管體； 一被安置於管體内和被設計用來與零件相接觸之電氣 傳導内層； 圍繞著官體用以產生一磁場之感應機構； 包含機構之裝置使得磁場能夠藉由該感應機構經過管 體而產生，因此，在内層中直接感應得到電流，且導致在 介於内層與待加熱零件中間之介面部位的附近產生局部加 熱作用。 因此’經由本發明，感應得到的電流和加熱作用是被 局限於内層’直接是在待加熱管件的附近，且並非是在管 體的厚度内產生。於是，依照本發明之裝置所具有的優點 是局部加熱塑造區域，直接是在介於塑造區域與材料中間 之介面部位的附近’且並非是在塑造管體的厚度内，此項 結果表示出主要的耗能節省狀況。此種裝置亦具有簡單和 製造成本低的優點。 在一項實施例中，包含機構之裝置使得在管體内的磁 場穿透深度是大於管體的厚度。 7 200906232 ^在—項實施例中，磁場的穿透深度是由下列公式來決 50x ( p/ ( 1/2 ’其中p為組成管體之非磁 !生材料的電阻係數’ μί·為材料的相對導磁係、數和F為在感 應機構内流動的電流頻率。 在一項實施例中，内層被安置於管體的内部表面上。a metal tube body designed to contain a part; an electrically conductive inner layer disposed within the tube body and designed to contact the part; an inductive mechanism surrounding the body for generating a magnetic field; The magnetic field can be generated by the induction mechanism passing through the tube body, so that current is directly induced in the inner layer, and local heating is caused in the vicinity of the interface portion between the inner layer and the part to be heated.

In this application example, the device is designed to create a cylindrical part consisting of a re-enterment of a ± W. The garment or model 1 has a tubular body 12 surrounded by a salty and sturdy body 14. Carcass 12 & consists of - non-magnetic material composed of stainless steel. The main body of the pipe body 〖2 is Α in the real column. The surface is lined with an inner layer 16 of a magnetic material, such as a nickel based alloy. It has an alloy of, for example, nickel, chromium or titanium. The inner layer 16 constitutes a region in which the two regions are designed to be used for the virtual force 敎* field and the heating region „ ^ Temple heating parts and/or parts to be molded are in contact with each other when the frequency is F. _ Electric 1丨 is supplied to the sensor mechanism for 14 days. The device is configured to make the current -12 when the magnetic _ 14 is used. The magnetic susceptor is generated in the magnetic inner layer 图. The model is used to twist: a ten-sided-half-section view of this ', ', S-shaped part or tube 18. The thickness of the part to be heated is ~ 200906232 is placed in the tube body 12 ^ J Π 4. The camping member 18 is, for example, made of a thermoplastic medium or a thermosetting medium composite ^^ ΛΑ ® 1 , and the sensor machine C ^ A, 143, A, " 5 is placed in the tube body: near the surface of the part' The above loops are passed through the inner cooling channel 15 through which the cooling fluid is allowed to flow. In order to induce a current in the ^ ^ oyster layer 16, the value of the thickness _ layer must not be: = The magnetic % generated around the loop of the tube 12 must be the penetration of the magnetic field through the tube of thickness ~ The degree is defined by a known skin thickness. The thickness of the skin 5 in the tube 12 is W and is determined by the following formula: δ = 5 〇χ ( ρ / ( Fx 〇) 1/2 where P is The resistivity of the non-magnetic material constituting the tube body 12 (unit: micro ohm 麓 m) = the relative magnetic flux and F is the frequency of the induced current (in Hz - for the non-magnetic material, called, Then the above formula becomes valley - 5 〇 X (P / F) 1/2. Therefore, it is known that the thickness of the skin is proportional to the resistivity of the non-magnetic material constituting the tube 12. For example, the resistivity is 3 A micro-ohm Dong meter, a non-magnetic material with a frequency F equal to 3 Hz, which has a skin thickness δ of 5 mm. Selecting a non-magnetic material with a resistivity 'helps the magnetic field to obtain the desired wear. Throughout the situation, the result of selecting stainless steel (4) is a suitable safety scheme between the resistivity and the mechanical resistance. In a device, the shaping process can be carried out. In the process, the pipe body 12 must bear the main Stress. However, the tube body u has a high resistivity Any non-magnetic material is made, for example, a manganese-based alloy having an alloying element such as nickel and copper. 200906232 Since the resistivity of the tube 12 is known, the frequency f of the induced current L is selected to be larger than the thickness. The skin thickness of ei. Preferably, the highest frequency system that produces such a condition will be selected. In fact, the Joule energy induced by the heat effect is proportional to #. Therefore, the energy generated when ϋ is higher The larger the application, the composition, the composition, the processing: the material, the processing will be in the frequency from 100 Hz to several kilohertz:: within the circumference to obtain a skin thickness of tens of millimeters. Therefore, the magnet body and the inner layer 16 are generated, and an induced current is generated in the inner layer 16 as a thirst current). Then, under the action of the above induced current 12, 2 is also heated by Joule action, so that in a very short time, the two β members 18 are heated and reach the desired temperature. Therefore, the present invention can be achieved by using inductive heating as a target in the vicinity of the interface portion of the material. In terms of the matter, it is limited to the thickness "...the thickness...in comparison with the thickness of the model 1〇, the thickness = ..., the effect. In addition - the aspect 'because the tube 12 is the crucible: the tube is Will bear a very small inductive: material benefits = ^ point is its surface heating effect:: Registered ", water from the device body" and the advantages of the structure of the pipe body 12 In fact, and fatigue) and 埶 properties (low mechanical resistance (for stress effects, etc.), the upper two efficient heat transfer for cooling will not provide the above: quality 200906232 in a preferred variant' The penetration depth of the magnetic field is such that the induced current in the inner layer 16 is generated at the interface between the inner layer 16 and the tube body 12. Therefore, the surface of the inner surface 16 that is in contact with the tube to be heated does not have any induced current. In other words, the thickness δ of the skin is greater than ei but 疋 is less than (ei+e2). Then, 'the surface of the inner layer 16 and the tube body 12. The p-position is heated by induction, and the heat generated is generated. Then, by conduction The sending direction is intermediate between the inner layer 丄6 and the part 丄8; the I surface σ| stands. For example, a resistivity is i 〇 micro ohm shame and the relative magnetic permeability is 500, and the frequency F is 3 〇〇. Hertz's inner layer of recording has a depth of penetration of about 41 mm in the magnetic field. Next, a sufficient thickness is provided to the inner layer, for example at least 0.5 μm, to ensure contact with the part. There will be no induced current passing through. The 2 sub-current is induced to be generated between the inner layer 16 and the part to be heated. The 4th position of this variant has the advantage of providing surface heating in accordance with the present invention. At the same time, the heating effect of the electrical transmission _ (for example, made of carbon fiber) is generated. The action of fixing the inner layer 1 of the magnetic material to the model tube is performed in different ways, for example, by attaching a metal piece or By the hoarding action of the material 'for example, plasma or electrolytic deposition. The magnetic material for the inner layer b is a magnetic compound having a salient temperature, together with a resistivity higher than copper. For example, magnetic The compound can be a recorded, complex and/or titanium-based steel. + u is sufficient to provide a more efficient heating result by induction. The main resistivity of the inner/inner layer is one. Excellent, the magnetic permeability of the material constituting the inner layer also affects the efficiency of induction 12 200906232 (refer to the formula mentioned above). In the variant, the model 1 〇 contains the tube 丨The internal internal press #20 (refer to Fig. 2) of 8 and is applied to the outer surface of the tubular member 18 during the molding operation. The above pressure mechanism 20 is, for example, a telescopic airbag device (in metal) Or Shi Xicheng 1) 4 is a cylindrical metal part, which may be tubular or solid, provided with juice for expansion as the temperature increases, and the expansion result is sufficient to place the tube 18 directly against the inner surface 16 . In another application example, the shape memory function of some alloys can also be used, so that the parts made of such materials can be used for the temperature (more (4) is the temperature value between the external environment temperature and the plastic k temperature) And have different shapes. Such a part is, for example, a thin metal plate wound thereon. Figure 3 shows a variation of the apparatus in which the inner layer is placed on the metal cores ~22. In this configuration, the device enables the magnetic field generated by the inductor to pass through the tubular body 12 and the tubular member 18 to the core & in other words, the depth of penetration of the magnetic field within the model 1〇 is greater than ^. In fact, the thickness of the skin is greater than ei' because the magnetic field will pass through the part to be heated, and the magnetic field will reach the inner layer 16 directly. Since it does not have electrical conductivity, the part 18 has no effect on the magnetic field environment. In the application example of the prior variation, the magnetic field induces eddy currents in the inner layer. The inner layer 16 is disposed on the outer surface of the core 22. In this variation, the tubular member 18 @heating action is obtained by the action of its internal surface. In this application example, the magnetic material of the 22 is similar to the material constituting the inner layer 16, and the material element of the α μ material is then composed of a single element of 2009 200932 32, thereby simplifying the manufacturing method of the core 22 . In a variant not shown in the drawings, the device 1G has two magnetic inner layers 'where the first layer is placed on the inner surface of the tubular body 12 (as shown in Figure 2) and the second layer is Placed on the outer surface of the core (as shown in Figure 3). In this configuration, the sensing mechanism is implemented such that the penetration depth of the magnetic field can be greater than (eh), causing the magnetic field to pass through the inner layer of the tubular body 12f and the part to be heated (without any effect on the magnetic field environment) In the inner layer, in the county, inductive electricity k is generated in the second inner layer. This configuration is used to obtain double heating of the tubular part, while occurring on its inner or outer surface. In fact, the tube 12 is an opening element so that the finished part can be discharged. In this application example, the tubular body 12 1 is composed of two τ members 121, 122 which are mutually movable with each other (refer to Fig. 4 or Fig. 5), and the tubular members constitute a tubular member. The tubular body 12t also has a cooling groove which is disposed in the thickness of the tubular body 12 and has a direction parallel to the symmetrical axis of the tubular body 12. The above grooves allow the cooling fluid to flow through, and after the deformation of the member, the parts are cooled. In a variation as shown in Figure 4, the tubular body includes an electric brake on a radial plane thereof for use by Jiang Xing. In this configuration, the electrical isolation between the two layers (2) ^ ^ and the 兀 兀 Ϊ 21 and 122 acts as an air gap, and the magnetic field generated by the inductor is Flow in the air gap. The magnetic field letter covers each component (2) #(2) on the inner and outer surfaces of the two components. 14 200906232 produces induced currents 13 and 14 . The advantage of this configuration is the ability to remove the effect of the penetration depth of the magnetic field within the 兀"21 and 122.

The enamel layer 16 T has the effect of removing the thickness of the electromagnetic skin as described above. The advantage of the shape is that it can be used to provide a greater degree of freedom to select 2 = to the current frequency in the inductor mechanism 14. All parameters $ are = 疋 'known to increase the frequency of the electromagnetic field will improve the effect of heating is the neck: the fruit will further reduce the thickness of the skin. Therefore, the advantage is made of magnetic material ..., for example, a kind And composition: is: (4) made to assemble to each of the two (tubes) with the electrical isolation layer 12I* 122 'in this application example, the non-such 125 is to be provided by the same isolation layer 123 Isolation. The garment is ideally implemented at a high frequency (for example, between _ kilohertz). In fact, the frequency of the snow will be chosen, :: the surface thickness is less than the thickness of the non-magnetic outer layer (will Is greater than i millimeters, Μ?: Due to the non-magnetic outer layer 124, the composition - electromagnetic shielding ^ electricity _ is unable to penetrate to the outer surface of the tube U. In addition, 15 200906232 = magnetic shielding: the layer is non-magnetic and has a low resistivity, The electromagnetic shielding = a very small feeling In the same way, as in the case of progressive Qitian fans, since the current 13 flows inside the tube body 12, the tube body 12# is made of a non-magnetic material, the s 12 It will react violently to inductive heating, thus producing a considerable amount of heating, producing electricity in the core, 22 in order. Therefore, double heating is applied to the tubular zero #18, simultaneously occurring on its inner surface. And on the outer surface. In order to prevent any heat loss in the tubular part, a non-magnetic shielding layer is provided between each of the elements 121, 122 and the isolating layer (2). A variation shown in FIG. Also provided for a tube made of a magnetic material having two electrically isolated portions (2) and 122 and having a non-magnetic shielding layer 124 and 125, but having no internal core. In addition to the magnetic inner layer 16 is located on the inner surfaces of the elements 121 and 122. The operation principle is the same as the application example of the g 4 (5). Therefore, the inner layer 16 is directly passed through the induced currents ^ and u, so that it is locally heated. In the above, since the inner layer 16 is made of the same magnetic material, the inner layer 16 is not significantly different from the inner surface of the tube. In order to prevent any energy loss, as shown in Fig. 5, the non-magnetic layer i 24 The upper layer and the upper layer will also separate the elements 121 and 122 of the spacer layer 123. If necessary, the above two mask layers will extend upward to reach the height of the inner layer 16. Such an arrangement can be particularly applied to the heating of solid parts and Molding effect. The device of the present invention is particularly suitable for use in a tubular or round body part made of a composite material such as a thermoplastic or thermosetting matrix composite. The device can be used to substantially reduce The required cycle time. The fact that Bu Xian Xi a part of the deformation processing is carried out, the sensing ι§ can be Jin I ancient & Because the device is directly injected into the inner layer 16. The attack 丨〇 is not used, in a large-scale manner, the thickness is often small, so that the inner layer 10 does not reach the required temperature. Α τ contact surface can quickly reach a traditional device with a real Gans... Known 洫 degree value, compared to the out and a short time L (five) only the rut less energy is dissipated, Eight, Yu Yu, because of the less heat for additional Xingqin ++ q phase twist, therefore, the 12 temples * and the cold department can be placed in the tube body ... close to the inner layer. Finally, because it is used to induce economics.
