我厂开发试制的CQA204型梳棉机是先进的纺织机械。剌毛辊(图1)为该设备上的一个重要部件。它的材质为HT200铸铁,总长1387mm,两端轴颈尺寸为φ40_(+0.002)~(+0.08)mm,螺纹部分长1013mm,为10头方牙螺纹,螺纹大径φ242±0.2mm,导程25.4mm,螺距2.54mm,螺纹槽宽1.017_0~(+0.025)mm,槽深1.525±0.05mm,螺纹表面粗糙度R_01.6,螺纹槽底圆柱面对A、B面的直线度0.05mm。刺毛辊尺寸精度要求高,加工难度大。为及时解决刺毛辊螺纹沟槽的加工,我们研制了一种特殊的加工刺毛辊螺纹沟槽的梳刀(图2)。
Our trial development CQA204-card is an advanced textile machinery. Embossing roller (Figure 1) is an important part of the device. It is made of HT200 cast iron with a total length of 1387 mm and a journal size of φ40 _ (+0.002) ~ (+0.08) mm at both ends. The thread length is 1013 mm and is 10 square threads. The thread diameter is φ242 ± 0.2 mm. 25.4mm, pitch 2.54mm, thread groove width 1.017_0 ~ (+0.025) mm, groove depth 1.525 ± 0.05mm, thread surface roughness R_01.6, the thread groove bottom cylindrical surface A, B surface straightness 0.05mm. Bristle roller dimensional accuracy requirements, processing difficult. In order to promptly solve the processing of the thread groove of the bristle roller, we developed a special comb knife for processing the thread groove of the bristle roller (Fig. 2).
