热镀锌机组活套小车左右导向板异型曲面的加工

The machining for non-conventional camber of left and right guide plate used in the looper carriage of the galvanizing line

热镀锌机组中,活套小车装配的导向板是典型的细长件,细长件的加工历来是机械加工中的难点,而且活套小车配装的左右导向板的导向面为异形曲面,这就使加工难度更大,制造方法更复杂。本文介绍了热镀锌机组活套小车左右导向板的制造工艺特点。通过合理安排各部位的加工留量及自然时效工序,专项措施与数控技术相结合,采取工序分散的加工原则,使产品质量完全达到了设计要求。

Normally it is very difficulty to machine the long and thin work piece, the guide plate for the looper carriage is a kind of typical long and thin piece, and the guide surface of left and right guide plates assembled on the looper carriage is a kind of non - conventional camber, which has more difficulties for the machining. This article introduces the characteristic of the manufacturing process for the guide plates. reasonable arrange machining allowance for each location and the process of nature maturing , meanwhile the special measures have, to be taken together with NC technology so that the quality of the products has been satisfactory.
