液压飞剪机的剪切控制

为了扩大生产规模，自行设计制造了一条冷弯机组生产线。该机组主要用来生产开口型材，所以采用了简单、实用的液压飞剪机。介绍了飞剪机的组成及控制原理等，并指出它的特点是控制简单，维护方便。

Cut-off Control of the Hydraulic Flying-Cut machine

In order to enlarge the production scale, on cold bending production line was designed and manufactured. It is mainly used to produce the open-type structural steel, so it adopts the simple and applicable hydraulic flying-cut machine. This article also introduces the structure and control principle of the flying-cut machine and points out its characteristic: simple control and easy maintenance.
