橡胶垫上的孔加工,一般用钻头或漏冲,但这些方法只限于加工小孔径。若需加工φ30以上的孔径时,用钻头或漏冲很难达到所需要的光洁度和精度。我们在实践中制作一个橡胶垫孔加工工具(如图所示),把工具体装在立钻上,加工了内燃机气缸体试水机上的橡胶垫孔,孔径为φ105毫米,光洁度达到5以上,尺寸精度达到±0.15毫米。这种划刀结构简单,易于制造,适合修理和试制工作。我们对软硬不同的耐油橡胶和高分子橡胶都成功地进行了加工。同理,也可以用此划刀在
Hole on the rubber mat processing, the general drill or leak Chong, but these methods are limited to the processing of small aperture. If you need to work with a diameter of φ30 or more, it is difficult to achieve the required finish and accuracy with a drill or leak-through. In practice, we make a rubber hole machining tool (shown), the tool body mounted on the vertical drilling, processing engine cylinder engine cylinder rubber pad hole, a hole diameter of φ105 mm, the finish of more than 5, Dimensional accuracy of ± 0.15 mm. This knife structure is simple, easy to manufacture, suitable for repair and trial work. We have successfully processed hard and soft oil-resistant rubbers and high-molecular rubbers. Similarly, you can also use this knife in
