在汽车生产中,用普通机用丝锥在中、低碳钢等塑性材料上加工小规格(尤其是M8以下)的螺孔,普遍存在着效率低、质量差、丝锥寿命低、易折断等弊病.随着汽车产品上轻合金材料的广泛应用(以铝合金居多),因内螺纹的疲劳强度和静强度低而导致螺纹秃扣的质量问题十分突出.而挤压丝锥的推广应用,将会使这些问题得到理想的解决.
In automobile production, ordinary machine taps are used to manufacture small-sized (especially M8 or less) screw holes on plastic materials such as medium and low carbon steel, which generally have the defects of low efficiency, poor quality, low tap life and easy breakage With the wide application of light alloy materials (mostly aluminum alloy) on automobile products, the quality problem of thread bald buckle is very prominent due to the fatigue strength and static strength of the internal thread, and the popularization and application of squeeze tap will So that these problems can be solved ideally.
