Description
本發明係有關於一種螺絲，特別是有關於具耐熱且具低膨脹系數的低熱膨脹螺絲。The present invention relates to a screw, and more particularly to a low thermal expansion screw having heat resistance and a low coefficient of expansion.
請參照圖1繪示先前技術的螺絲螺合二相異材質的物件示意圖。因應世界精密工業設備及半導體光電產業需求，在許多設備中，皆具有藉由螺絲10以將陶瓷材料零件1與金屬材料零件2鎖在一起的部位。然而，機台使用中會產生熱量，若連結的螺絲10使用一般金屬螺絲，便會因熱脹冷縮使陶瓷材料零件1破裂造成機台故障，故此螺絲10目前通常為陶瓷材料螺絲。Please refer to FIG. 1 , which is a schematic diagram of an object of the prior art screw-screw two-phase material. In response to the needs of the world's precision industrial equipment and the semiconductor optoelectronic industry, in many devices, there are screws 10 for locking the ceramic material part 1 and the metal material part 2 together. However, when the machine is used, heat is generated. If the connected screw 10 uses a general metal screw, the ceramic material part 1 may be broken due to thermal expansion and contraction, so the screw 10 is usually a ceramic material screw.
然而，陶瓷材料螺絲雖具有良好的低熱膨脹性質以及生產變異性小。但是，陶瓷材料螺絲在成形上較為困難，因此製造成本相對較高。其次，陶瓷材料螺絲制震能較低、延展性能不佳，故很容易在受到機台運作時產生的震動，產生碎裂的情形。However, ceramic material screws have good low thermal expansion properties and low production variability. However, ceramic material screws are difficult to form, so the manufacturing cost is relatively high. Secondly, the ceramic material has low vibration-damage energy and poor ductility, so it is easy to generate vibration when it is subjected to the operation of the machine.
為解決上述問題，本發明揭露一種具耐熱，且具較低的熱膨脹系數的螺絲。In order to solve the above problems, the present invention discloses a screw having heat resistance and a low coefficient of thermal expansion.
本發明所揭露的螺絲，其係以低熱膨脹合金形成，並包括一柄軸部。柄軸部具有螺紋，螺絲之柄軸部的材質為一鐵鎳合金，鐵鎳合金除鐵之外的成份與重量百分比包括：鎳：33.0至36.0wt%；碳：1.7至2.0wt%；錳：至少0.4wt%；矽：1.0至2.0wt%；磷：至少0.4wt%；以及，鈮：0.1至9.0wt%。The screw disclosed in the present invention is formed of a low thermal expansion alloy and includes a shaft portion. The shank shaft has a thread, the shaft portion of the screw is made of an iron-nickel alloy, and the composition and weight percentage of the iron-nickel alloy other than iron include: nickel: 33.0 to 36.0 wt%; carbon: 1.7 to 2.0 wt%; manganese : at least 0.4 wt%; 矽: 1.0 to 2.0 wt%; phosphorus: at least 0.4 wt%; and, 铌: 0.1 to 9.0 wt%.
本發明之特點係在於本發明的螺絲受熱時可避免過度膨脹而導致所鎖固的陶瓷材料部件破裂，而且適用於高溫環境及設備。其次，本發明所揭露螺絲的制震能較高、延展性能佳，故不容易受到機台運作時產生的震動而產生碎裂的問題，適用性亦較高。而且，亦不需要為螺絲鎖固的部位以額外設計導熱性控制結構，亦能提升元件於機台的配置彈性。The present invention is characterized in that the screw of the present invention can avoid excessive expansion when heated, resulting in cracking of the locked ceramic material component, and is suitable for high temperature environments and equipment. Secondly, the screw disclosed in the present invention has high seismic energy and good ductility, so it is not susceptible to the vibration generated by the operation of the machine and causes chipping, and the applicability is also high. Moreover, there is no need to additionally design a thermal conductivity control structure for the screw locking portion, and it can also enhance the flexibility of the component arrangement on the machine table.
茲配合圖式將本發明較佳實施例詳細說明如下。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described in detail below with reference to the drawings.
首先請參照圖2繪示本發明揭露的螺絲結構示意圖之第一實施例。此結構皆是將具低熱膨脹合金的工件，經由滾製或切割，以在工件外環表面形成螺紋，再將工件經由溶液熱處理、淬火、回火與表面處理等熱處理作業以完成螺絲的製作。其中，熱處理條件為加熱到850℃並持溫一小時，然後淬水處理，回火處理條件為回火至350℃並持溫二小時，然後爐冷至室溫。First, please refer to FIG. 2 to illustrate a first embodiment of a screw structure schematic diagram disclosed in the present invention. This structure is to make a workpiece with a low thermal expansion alloy, through rolling or cutting, to form a thread on the outer ring surface of the workpiece, and then through the heat treatment of solution heat treatment, quenching, tempering and surface treatment to complete the screw. The heat treatment condition is heating to 850 ° C and holding the temperature for one hour, and then quenching the water, and the tempering treatment condition is tempering to 350 ° C and holding the temperature for two hours, and then cooling the furnace to room temperature.
圖2繪示的螺絲20，其為低熱膨脹合金所形成。螺絲20具有一柄軸部21。此柄軸部21具有螺紋22，依據設計需求可為外螺紋或內螺紋，於此以外螺紋進行說明。柄軸部21的材質為鐵鎳合金，此鐵鎳合金成份與重量百分比包括：鎳：33.0至36.0wt%；碳：1.7至2.0wt%；錳：至少0.4wt%；矽：1.00至2.00wt%；磷：至少0.4wt%；鈮：0.1至9.0wt%。其餘部分為鐵以及其他不純物質含量。其中，wt指重量(weight)。Figure 2 illustrates a screw 20 formed of a low thermal expansion alloy. The screw 20 has a stem portion 21. The shank portion 21 has a thread 22, which may be an external thread or an internal thread depending on design requirements, and the other threads are described. The material of the shank portion 21 is an iron-nickel alloy, and the composition and weight percentage of the iron-nickel alloy include: nickel: 33.0 to 36.0 wt%; carbon: 1.7 to 2.0 wt%; manganese: at least 0.4 wt%; 矽: 1.00 to 2.00 wt. %; phosphorus: at least 0.4% by weight; 铌: 0.1 to 9.0% by weight. The rest is iron and other impurities. Where wt refers to weight.
柄軸部21的一端連接於一螺絲頭部23，此螺絲頭部23的材質可為碳鋼、輕合金(如鋁合金)、或是與柄軸部21的材質相同，即鐵鎳合金。其中，當製造者亦使用鐵鎳合金作為螺絲頭部23的材質時，可以一體成形的方式以製造此螺絲20。One end of the shank portion 21 is connected to a screw head portion 23, which may be made of carbon steel, a light alloy (such as an aluminum alloy), or the same material as the shank portion 21, that is, an iron-nickel alloy. Here, when the manufacturer also uses an iron-nickel alloy as the material of the screw head 23, the screw 20 can be manufactured integrally.
而且，為彈性的調節螺絲20硬度，亦可於製造螺絲20的淬火、回火處理後，對螺絲20進行滲碳處理。Further, for the elasticity of the adjusting screw 20, the screw 20 may be carburized after the quenching and tempering treatment of the screw 20.
此外，可對螺紋22部位加以硬式陽極化處理，以於螺紋22部位表面形成一氧化層。或更進一步者，於螺紋22部位進行降低磨擦力浸漬處理，如對螺紋22表面碳化、氮化處理，以於氧化層上附加一抗磨擦力鍍層。或再更進一步，將螺絲20以聚四氟乙烯(即俗稱的鐵弗龍)加以浸漬。藉此，除提升螺絲20硬度，亦能提升螺絲20的耐用性。In addition, the portion of the thread 22 can be hard anodized to form an oxide layer on the surface of the portion of the thread 22. Or, further, a friction reducing impregnation treatment is performed on the portion of the thread 22, such as carbonizing and nitriding the surface of the thread 22 to apply an anti-friction coating to the oxide layer. Or still further, the screw 20 is impregnated with polytetrafluoroethylene (commonly known as Teflon). Thereby, in addition to the hardness of the lifting screw 20, the durability of the screw 20 can be improved.
另一方面，亦可對螺紋22部位只進行抗磨擦力浸漬處理，以形成抗磨擦力鍍層，藉此提升螺絲20的耐用性。On the other hand, only the portion of the thread 22 can be subjected to an anti-friction immersion treatment to form an anti-friction coating, thereby improving the durability of the screw 20.
請參閱圖3繪示本發明揭露的螺絲結構示意圖之第二實施例。圖3繪示的螺絲30具有一柄軸部31，柄軸部31表面具有螺紋32。柄軸部31的材質為第一實施例所述的鐵鎳合金。Please refer to FIG. 3 , which illustrates a second embodiment of the screw structure disclosed in the present invention. The screw 30 illustrated in FIG. 3 has a shank portion 31 having a thread 32 on its surface. The material of the shank portion 31 is the iron-nickel alloy described in the first embodiment.
柄軸部31的一端連接於一螺絲頭部33，此螺絲頭部33為六角頭。螺絲頭部33的材質可為前述的碳鋼、輕合金、或是與柄軸部31材質相同的鐵鎳合金。其中，當鐵鎳合金作為螺絲頭部33的材質時，此螺絲30可以一體成形的方式而被製造。One end of the shank portion 31 is coupled to a screw head 33 which is a hex head. The material of the screw head 33 may be the aforementioned carbon steel, a light alloy, or an iron-nickel alloy having the same material as that of the arbor portion 31. Among them, when an iron-nickel alloy is used as the material of the screw head 33, the screw 30 can be manufactured integrally.
請參閱圖4繪示本發明揭露的螺絲結構示意圖之第三實施例。圖4繪示的螺絲40具有一柄軸部41，柄軸部表面具有螺紋42。柄軸部41的材質為第一實施例所述的鐵鎳合金。Please refer to FIG. 4 , which illustrates a third embodiment of the structure of the screw disclosed in the present invention. The screw 40 illustrated in FIG. 4 has a shank portion 41 having a thread 42 on its surface. The material of the shank portion 41 is the iron-nickel alloy described in the first embodiment.
柄軸部41的第一端44連接於一螺絲頭部43，第二端45連接於一螺絲尖部46。螺絲40被製造時，螺紋42可被設計延伸至螺絲尖部46，以使整個螺絲40形成一自攻螺釘。The first end 44 of the shank portion 41 is coupled to a screw head portion 43, and the second end portion 45 is coupled to a screw tip portion 46. When the screw 40 is manufactured, the thread 42 can be designed to extend to the screw tip 46 such that the entire screw 40 forms a self-tapping screw.
螺絲頭部43與螺絲尖部46的材質可為前述的碳鋼、輕合金、或是與柄軸部材質相同的鐵鎳合金。其中，當螺絲頭部43與螺絲尖部46的材質為鐵鎳合金時，此螺絲40可以一體成形的方式而被製造。The material of the screw head portion 43 and the screw tip portion 46 may be the aforementioned carbon steel, a light alloy, or an iron-nickel alloy having the same material as that of the shank portion. Here, when the material of the screw head portion 43 and the screw tip portion 46 is an iron-nickel alloy, the screw 40 can be manufactured integrally.
請參閱圖5繪示本發明揭露的螺絲螺合二相異材質的物件示意圖。前述中的第一實施例至第三實施例，鐵鎳合金的熱膨脹係數會被控制小於或等於4.5x10-6 /℃。於20℃至200℃之間的熱膨脹係數幾乎相等。Please refer to FIG. 5 , which is a schematic diagram of the object of the screw-screwed two-phase material disclosed in the present invention. In the first to third embodiments of the foregoing, the coefficient of thermal expansion of the iron-nickel alloy is controlled to be less than or equal to 4.5 x 10 -6 /°C. The coefficients of thermal expansion between 20 ° C and 200 ° C are almost equal.
以現今精密工業設備及半導體光電產業需求的許多設備為例，此類設備多半具有需將陶瓷材料零件1與金屬材料零件2鎖在一起的部位。此例中，以圖4繪示的螺絲30為例。藉由螺絲30以螺合陶瓷材料零件1與金屬材料零件2時，即便機台使用中產生熱量，螺絲30亦不會有過度的熱脹冷縮而使陶瓷材料零件破裂，進而造成機台故障的情形發生。For example, many of the equipment required by today's precision industrial equipment and the semiconductor optoelectronic industry, such equipment mostly has a portion where the ceramic material part 1 and the metal material part 2 need to be locked together. In this example, the screw 30 shown in FIG. 4 is taken as an example. When the ceramic material part 1 and the metal material part 2 are screwed by the screw 30, even if heat is generated during the use of the machine, the screw 30 does not have excessive thermal expansion and contraction, and the ceramic material part is broken, thereby causing the machine to malfunction. The situation happened.
