深圳螺丝厂家介绍自攻螺丝的由来及发展历程

自1914年自攻螺丝开始商品化。第一次的设计主要源自木螺丝─系属可渗碳钢锥尾A型螺纹成型螺丝。当时主要的用途是用在空调系统导管上铁皮的接合,因此又叫做铁皮螺丝。经过80余年的发展,共可分为四个时期─螺纹成型、螺纹切削、螺纹滚成及自钻。Since 1914 self-tapping screws began commercialization. The first design is mainly from wood screws - is a carbonaceous steel cone-shaped A-type thread forming screws. At that time the main purpose is to use in the air conditioning system on the catheter on the metal joint, so called metal screws. After more than 80 years of development, can be divided into four periods - thread forming, thread cutting, thread rolling and self drilling.

螺纹成型自攻螺丝(ThreadFormingTappingScrews)─系直接由铁皮螺丝发展而来,螺纹成型自攻螺丝使用时须预先钻孔,再将螺丝旋入孔中,强力挤出配合阴螺纹,而原来在阴螺纹位置上的材料将被挤到阳螺纹之间,因此螺纹成型自攻螺丝。仅可适用于薄且具有可塑性的材料,因此又发展出;螺纹切削自攻螺丝(ThreadCuttingTappingScrews)在螺纹的尾端切割出或多道的切削口,使能在旋入预钻孔时,利用螺丝尾部及牙部以类似螺丝攻的方式切削出配合阴螺纹。它可以用在厚板,比较坚硬或易碎等不易塑造的材料上。Threading screw (ThreadFormingTappingScrews) ─ ─ directly from the development of metal screws, thread forming self-tapping screws to be used in advance drilling, and then screw into the hole, the strong extrusion with the female thread, and the original in the female thread The material on the position will be squeezed between the male threads, so the thread is molded from the tapping screw. Can only be applied to thin and plastic materials, and therefore developed; thread cutting tapping screws (ThreadCuttingTappingScrews) at the end of the thread cut out or multi-channel cutting mouth, enabling the screw in the pre-drilled hole, the use of screws The tail and the teeth in a similar way to cut the screw with the female thread. It can be used in thick plate, relatively hard or fragile and so difficult to shape the material.

 

  螺纹滚成自攻螺丝(ThreadRollingTappingScrews)、三角牙自攻螺丝,又称为TypeTT(TypeTai目前仍有专利)系基于成型自攻螺丝攻的原理发展而成,螺纹滚成自攻螺丝具有特殊设计的螺纹及尾端使螺丝可以在断续的压力下自行滚成配合的阴螺纹。同时在孔周围的材料可以更轻易的填补自攻螺丝螺纹及牙底的空间,由于其磨擦力较螺纹成型自攻螺丝为小,因此可以使用在更厚的材料上,旋转所需的扭矩更好控制,且组合后强度更高。螺纹滚成自攻螺丝其工程标准定义比成型或切削自攻螺丝在材料,热处理,强度上的定义更高且更为明确,使得螺纹滚成自攻螺丝成为真正的”构造用”扣件。ThreadTollingTappingScrews, Triangle Teeth Screws, Also known as TypeTT (TypeTai is still patented) is based on the principle of forming self-tapping screw attack, the thread rolled into a self-tapping screw with a specially designed Thread and tail so that the screw can be intermittently under the pressure of their own rolling into the female thread. At the same time in the hole around the material can be more easily fill the tapping screw thread and tooth bottom space, because of its friction than the thread forming tapping screws for small, so you can use in thicker materials, the torque required for rotation Good control, and the combination of higher strength. Threaded into a self-tapping screw The engineering standard defines a higher and more definite definition of the material, heat treatment, strength than the forming or cutting tapping screw, making the thread roll into a self-tapping screw to become a true "structural" fastener.

 

钻尾自攻螺丝(SelfDrillingTappingScrews)─又称为Tec,在组装自攻螺丝的所有过程中,很耗费成本的是预钻孔的准备.自攻螺丝的使用,必需先钻孔。而且孔径也必需限制。无需预钻孔而在某些方面可以节省成本。这就是集钻,攻,旋紧于一次作业的钻尾自攻螺丝。钻尾螺丝的表面硬度及心部硬度比一般自攻螺丝高一点,这是因为钻尾螺丝多了一个钻孔的作业,另外钻尾螺丝尚需作贯穿试验,用以测试螺丝可以在规定时间内钻孔并攻出螺纹。Self-tapping screw (SelfDrillingTappingScrews), also known as Tec, are costly pre-drilled in all the processes of assembling self-tapping screws. The use of self-tapping screws requires drilling first. And the aperture must also be limited. No pre-drilled holes can be saved in some way. This is the set of drilling, attack, tightened in a job drilling tail tapping screws. Drilling screw surface hardness and hardness of the heart than the general self-tapping screws a little higher, this is because the drilling screw more than a drilling operation, while drilling tail screws still need to run through the test to test the screw can be specified in the time Drill holes and thread.

 

上述为四种主要自攻螺丝的设计及发展过程,另有两种为特殊螺纹设计的螺丝:

 

  第一种为:高低牙自攻螺丝(High–LowTappingScrews)─使用在塑料或其它低密度材料。双螺纹设计,高螺纹(牙部外径较大)具有更平更尖锐螺纹角为30度的螺纹型式。低螺纹(牙部外径较小)具有一60度的螺纹角,牙高只有高螺纹的一半。高低螺纹的组合设计降低了旋转扭矩,改善了拉出强度,大幅降低了组合工件破裂的危险性另一种用在建筑工业上乾墙(Drywall)的组装用途上。具有此类螺纹设计的自攻螺丝特别适合于塑料,零件板及木头。High and low tooth tapping screws (High-LowTappingScrews) - used in plastic or other low-density materials. Double thread design, high thread (larger tooth diameter) with more flat and more sharp thread angle of 30 degrees of thread type. Low thread (smaller tooth diameter) has a screw angle of 60 degrees, tooth height only half of the high thread. The combined design of the high and low threads reduces the rotational torque, improves the pull-out strength, significantly reduces the risk of the combined workpiece rupture, and the other is used in the assembly of drywall in the construction industry. Self-tapping screws with such thread design are particularly suitable for plastics, parts boards and wood.

 

  第二种为:双螺纹自钻尾喇叭头自攻螺丝(TwinLeadSelfDrillingPointTappingScrews)─组装时可以轻易旋入乾墙,在钢铁牙条上自钻一洞并攻出配合的阴螺纹。其喇叭头具凹入的承受面可以在旋入时不至于破坏到壁纸或石膏表面。大多数的自攻螺丝均属于商业用途,例如当自攻螺丝以组合螺丝(SEMS)提供时,可以提供更紧密的服务。而螺丝如具有粗细螺纹特殊设计者则系著眼于组装后的防松。Double thread self-tapping tail tapping screw (TwinLeadSelfDrillingPointTappingScrews) - assembly can be easily screwed into the dry wall, in the steel teeth on the drill hole and attack with the female thread. The horn head with a concave bearing surface can be inserted into the wallpaper or gypsum surface will not damage. Most of the self-tapping screws are commercially available, for example, when the tapping screws are supplied with combined screws (SEMS), they can provide tighter service. While the screw, such as the thickness of the thread with a special designer is tied to the assembly after the anti-loose.
