Abstract
The invention relates to a metal stacking/drawing deformation detection device in steel tube diagonal continuous rolling, belonging to the field of seamless steel tube diagonal rolling production. The detection device is characterized by comprising front and back revolving bodies, and a middle non-revolving body, wherein the front and back revolving bodies are respectively connected with free shift ends of driving shafts of front and back rolling mill sections of a diagonal continuous rolling mill; and a displacement sensor is installed in the middle non-revolving body and used for reflecting stacking/drawing steel deformation of the rolled piece, thereby adjusting the speed of the driving shaft of the back rolling mill section in time. The detection device can effectively solve the problems in stacking/drawing steel and speed matching in the diagonal continuous rolling process.
Description
Technical field
The invention belongs to seamless steel pipe oblique milling production field and in particular in a kind of oblique tandem rolling of steel pipe metal stack draw deformation
Detection means.
Background technology
At present, steel pipe's production equipment is mainly made up of perforating apparatus, rolling tube equipment and follow-up equipment etc., and its shortcoming is: work
Skill long flow path, equipment investment is big.A kind of oblique tandem rolling of three rollers producing tubing or bar is mentioned in patent of invention cn103316917b
Machine, its structural feature is that it includes leading portion milling train and back segment milling train.In front and back section milling train, construction identical, every section of milling train
Inside there are 3 groups of roll shaftings being both needed to drive, in every group of roll shafting through shaft coupling and motor connection, the other end can for drive shaft one end
Free play.Due in front and back's section milling train, frame be bolted together so that free play end concentrates on entirely
In the middle of frame, drive end is dispersed in front end and end.In continuous rolling process, whether section milling train, speed mate in front and back, direct shadow
Ring the operation of rolling be smoothed out and rolled piece quality.The speed of leading portion milling train is constant, if back segment rolling mill speed mistake
Soon it may appear that drawing steel phenomenon, or even break rolled piece；If back segment rolling mill speed excessively slow it may appear that piling of steel phenomenon, rolled piece can be twisted
Fried dough twist.
Content of the invention
The present invention seeks to proposing the detection means that metal stack in a kind of oblique tandem rolling of steel pipe draws deformation, can effectively solve to send out
Oblique tandem mill push-and-pull steel problem present in rolling in bright patent cn103316917b, and section milling train, speed in front and back
The problem joined.
The present invention is realized in.As shown in Figure 1, 2, 3, it is characterized in that including forward and backward revolving body and middle non-time
Swivel.The structure of described middle non-revolved body is that inner sleeve 5 is sleeved in outer sleeve 7, and the flat key 9 by axially moving
Link together；The big section of the little axle in front end 3 of step is arranged in the leading portion of inner sleeve 5 by front end ball bearing 13, front end
Transparent cover 4 is arranged on the front end of inner sleeve 5 by screw, and the top of the little axle in front end 3 is connected with front end universal joint 2, front end universal joint 2
The other end be connected with first axle side pressure lid 1；The big section of the little axle in rear end 3 ＇ is arranged on outer sleeve 7 by rear end ball bearing 13 ＇
In back segment, rear end transparent cover 4 ＇ is arranged on the rear end of outer sleeve 7 by screw, and the top of the little axle in rear end 3 ＇ is with rear end universal joint 2 ＇ even
Connect, the other end of rear end universal joint 2 ＇ is connected with the second axle head gland 1 ＇；It is provided with tactile fast 12 in the chamber of outer sleeve 7, including
The displacement transducer 6 being connected with control system is installed in sleeve 5 chamber, the contact of displacement transducer 6 is inconsistent with contact block 12；The
One axle head gland 1 and the second axle head gland 1 ＇ respectively with front and back section milling train, be connected.
Advantage of the present invention and good effect are as follows:
The present invention can efficiently solve the rolled piece push-and-pull problem on deformation occurring in the oblique continuous rolling process of steel pipe.

Specific embodiment:
As shown in figure 3, first axle side pressure lid 1 is connected with the drive shaft of leading portion milling train free play end, by the second axle head
Gland 1 ＇ is connected with the drive shaft of back segment milling train free play end.When initial, after there is certain stroke in compression displacement sensor 6
It is fixed in inner sleeve 5 chamber, displacement transducer 6 has an initial value, during work, the drive shaft turns of leading portion milling train, before drive
Revolving body rotates；The drive shaft turns of back segment milling train, after drive, revolving body rotates；Middle non-revolved body is in resting state.
When drive shaft speed n2 of drive shaft speed n1 of present segment milling train and back segment milling train does not match that, rolled piece meeting
Produce heap and draw deformation, lead to roll shafting meeting play, the displacement transducer 6 being arranged in inner sleeve 5 chamber can measure play in time
Amount, is adjusted drive shaft speed n2 of back segment milling train in time, is allowed to drive shaft speed n1 with leading portion milling train by control system
Match.
