一种组合式异型铸造管及生产方法
摘要：
本发明涉及一种组合式异型铸造管及生产方法，它属于一种异型离心铸铁管及其生产方法。本发明主要是解决现有的异型管存在着精度低、效率低、综合价格高和内外表面粗糙度差的技术问题。本发明采用的技术方案是：一种组合式异型铸造管，它由粘接件、粘接剂和直管构成，所述粘接件由砂铸法铸造成型；直管由离心铸造制作，直管的粘接面与粘接件的粘接配合面采用粘接剂粘接使直管和粘接件连成一体。该生产方法的步骤为：a.对粘接件的粘接配合面进行机加工；b.对直管的粘接面进行机加工；c.配制粘接剂；d.粘接粘接件和直管；e.晾置铸管。
摘要（英）：

The invention relates to a combined special-shaped cast pipe and a production method thereof, and belongs to a special-shaped centrifugation cast iron pipe and a production method thereof. The technical problems of low precision, low efficiency, high comprehensive price and poor outer surface roughness degree of the existing special-shaped pipe can be mainly solved. The combined special-shaped cast pipe is characterized in that the combined special-shaped cast pipe consists of a bonding part, a bonding agent and a straight pipe, wherein the bonding part is cast and shaped by a sand casting method; the straight pipe is cast and made through centrifugation; the bonding surface of the straight pipe and the bonding matching surface of the bonding part are bonded by bonding agents so that the straight pipe and the bonding parts are connected into a whole. The production method comprises the following steps of a, performing machine processing on the bonding matched surface of the bonding part; b, performing machine processing on the bonding surface of the straight pipe; c, preparing the bonding agents; d, bonding the bonding part and the straight pipe; e, drying the cast pipe.
