Described measurement mechanism 4 is scale measurement mechanisms, directly by being provided with and the corresponding flexibility scale of the amount of feeding, thereby push pipe axle 3 amount of feeding is converted to the flexibility for the treatment of crooked steel pipe 2, and by manually reading flexibility, and then Artificial Control push pipe axle 3.Certainly, also can not change, and by the configuration transitions table, obtain the corresponding amount of feeding of flexibility by tabling look-up before construction, by amount of feeding control, but this mode is more loaded down with trivial details.

Concrete, described measurement mechanism 4 comprises with the needle pivot 42 of push pipe axle 3 axially-movables, the scale 41 of fixed-site.By the cooperate indicating graduation of needle pivot 42 with scale 41.Certainly, the scale measurement mechanism also can be to be hinged on the push pipe axle 3 and with the pointer that 3 motions of push pipe axle swings, to reach corresponding angle scale, perhaps tape measure, tolling measurement structure etc.

At this moment, the amount of feeding of corresponding different tube diameters steel pipe can be corresponding respectively by a plurality of different scales of sign to the conversion of flexibility, and this mode accuracy of reading is not high, but simple in structure, cost is low.

Measurement mechanism 4 also can be a self-operated measuring unit, and as distance measuring sensor, displacement transducer etc., measurement result is by digital display and by manually reading, and then Artificial Control push pipe axle 3.The characteristic point that sensor is set with certain frequency scanning, the amount of feeding can show this mode accuracy of reading height, but cost height by corresponding change-over circuit conversion and by numeral to the conversion of flexibility.

When measurement mechanism 4 adopts self-operated measuring unit, also can be by reading automatically, at this moment, control device adopts automaton, automaton reads the position signalling or the amount of feeding signal of self-operated measuring unit scanning acquisition automatically and calculates in real time and obtains flexibility, forms the control signal of push pipe axle 3 simultaneously, and driver element drives push pipe axle 3 under control signal is controlled, this mode control accuracy is the highest, but cost is also the highest.

Adopt and manually to read, and then during Artificial Control push pipe axle 3,, make push pipe axle 3 in the stroke end in order further to increase the accuracy of control, when promptly flexibility meets the demands, feed-disabling automatically, described control device comprises the position limiting structure of push pipe axle 3.Thereby when the stroke end, the position-limiting action by position limiting structure makes push pipe axle 3 feed-disablings.
