技术领域technical field
本发明涉及丝攻技术领域，具体是指新型无屑丝攻。The invention relates to the technical field of wire tapping, in particular to a novel chipless wire tapping.
背景技术Background technique
目前，铝合金压铸件在汽车领域使用越来越广泛。尤其是国家倡导节能减排的今天，铝合金压铸件在新能源汽车的应用更加突出。其中铝合金电子控制器外壳它不仅保护着汽车计算机的神经中枢，还起着散热.密封及电路屏蔽的作用。所以，加工出合格的电控外壳尤为重要。目前，电子控制器外壳的内螺纹加工有以下两种方式。At present, aluminum alloy die castings are more and more widely used in the automotive field. Especially today when the country advocates energy saving and emission reduction, the application of aluminum alloy die castings in new energy vehicles is more prominent. Among them, the aluminum alloy electronic controller shell not only protects the nerve center of the car computer, but also plays the role of heat dissipation, sealing and circuit shielding. Therefore, it is particularly important to process a qualified electronic control housing. At present, the internal thread processing of the electronic controller housing has the following two methods.
1.切削加工：切削加工方式可加工出标准牙型的内螺纹。但加工后的螺纹受制于压铸件缩孔及沙孔的影响，螺纹强度会有所降低，无法满足汽车产品的螺纹扭矩要求。1. Cutting processing: the cutting processing method can process the internal thread of the standard tooth shape. However, the processed thread is subject to the influence of shrinkage cavity and sand hole in the die-casting part, and the thread strength will be reduced, which cannot meet the thread torque requirements of automotive products.
2.挤压加工：挤压加工方式通过挤压金属成型，使金属材料发生塑性变形流动，从而形成内螺纹，挤压时在螺纹表面形成力一层冷硬层，可以提高螺纹的强度和耐磨性。可满足汽车产品的螺纹扭矩要求。但该加工方式无法加工出标准牙型的内螺纹，该方式加工的内螺纹牙尖处呈不规则的火山口形状，该牙尖形状很容易因外力作用而脱落。由于压铸铝材料中的硅含量均在7％-13％之间，随着硅的含量增加铝合金材料的抗拉强度会逐渐下降。由于压铸铝合金材料的特性就使得挤压加工方式加工的内螺纹牙尖很容易在螺牙检测.清洗.装配等环节中受力脱落，从而造成产品清洁度超标，脱落的较大铝渣甚至可能造成电路板短路。。2. Extrusion processing: the extrusion processing method is formed by extruding metal, so that the metal material undergoes plastic deformation and flow, thereby forming an internal thread. During extrusion, a layer of chilled hard layer is formed on the thread surface, which can improve the strength and durability of the thread. Abrasive. It can meet the thread torque requirements of automotive products. However, this processing method cannot produce standard tooth-shaped internal threads, and the cusps of the internal threads processed by this method have an irregular crater shape, and the cusp shape is easy to fall off due to external force. Since the silicon content in the die-casting aluminum material is between 7% and 13%, the tensile strength of the aluminum alloy material will gradually decrease as the silicon content increases. Due to the characteristics of the die-casting aluminum alloy material, the cusp of the internal thread processed by extrusion processing is easy to fall off under the force of the thread inspection, cleaning, assembly, etc., resulting in excessive cleanliness of the product, large aluminum slag that falls off or even It may cause a short circuit on the circuit board. .
