Description
Technical field
The utility model relates to the technological improvement substituting godet rolling device when light-wall pipe produced by a kind of pipe mill with guide agency, substitutes disc guiding device when light-wall pipe produced by especially a kind of pipe mill with guide agency.
Background technology
ACCU ROLL pipe mill is a kind of novel pipe mill based on Diesel's pipe mill developed by Ai Tena standard engineering company of the U.S., main feature is tapered, the large godet of roll, roll axis crossingly with roll line forms roll off angle, adopt retained mandrel to operate simultaneously, maximum percentage elongation can reach 3.0, diameter-wall-rate reaches 35, product scope is wide, milling train operating flexibility is large, and product surface quality, geometric accuracy are high, and lumber recovery is very high.This machine adopts major diameter to rotate godet, and object is the longitudinal pulling force increasing rolled piece, is conducive to metal and flows in pass, be limited in pass and spread.But this machine is because the flash corners of steel pipe whipping phenomenon by godet working face collapses in the operation of rolling, and large godet working face very easily weares and teares, and add steel pipe manufacturing cost, steel tube surface precise decreasing, directly affects product surface quality simultaneously.In addition, owing to using large godet pass closure bad, especially when rolling D/S >=28 light-wall pipe, operation of rolling extremely unstable, instrument consumption is large, and the problems such as scuffing, end wall thickness low precision often appear in product surface.Therefore, need a kind of guide plate to substitute disc guiding device when light-wall pipe produced by ACCU ROLL pipe mill, change after wearing and tearing and save time, save material, reduce tube rolling production cost.
Summary of the invention
The deficiency that the utility model exists for prior art, disc guiding device is substituted with guide agency when providing a kind of pipe mill to produce light-wall pipe, not only structure is simple, volume is little for it, lightweight, install and change easily, and pass good seal, rolling is stable, good product quality, light-wall pipe lumber recovery are high.
The utility model solves the technical scheme that its technical problem adopts: substitute disc guiding device with guide agency when light-wall pipe produced by the pipe mill be made up of guide plate, cone-shaped roll, plug, frame, its special character is: the left and right cone-shaped roll that a little tail is large is arranged in the roller case of pipe mill main frame roll device, left and right is arranged, driven separately by direct current generator, two-dimentional adjustable all around; Upper and lower two pieces of arc-shaped guide plates are arranged on the upper and lower guide plate clamping device on upper and lower guide plate frame respectively, and upper and lower guide plate clamping device is for arrange up and down, and front and back are adjustable up and down; Matched by left and right two cone-shaped rolls and upper and lower two pieces of guide plates and form a blind bore type space, by adjusting device adjustment pass size.
Described upper guide plate clamping device, is provided with guide plate stay hook in side, upper guide plate frame bottom, and opposite side is provided with the guide plate sliding hook be connected with bolt, and upper guide plate is arranged between guide plate stay hook and guide plate sliding hook, and by the nut check on bolt.
Described bottom guide clamping device, is provided with guide plate stay hook in the side, top of bottom guide frame, and opposite side is provided with the guide plate sliding hook be connected with bolt, and bottom guide is arranged between guide plate stay hook and guide plate sliding hook, and by the nut check on bolt.
Described pipe mill guide plate, the front portion of its longitudinal direction is approach cone, and rear portion is for going out prostomum, approach cone and going out between prostomum for compression strap, the cross section of guide plate is provided with flash and low limit, and its flash coordinates with roll, and guide plate two ends are provided with the fixed block matched with guide plate clamping device.
Make godet into guide plate, when pipe mill carries out pass adjustment, by guide plate flash near roll, the closure of pass can be improved, reduce gap values between rollers, solve the problem of closure difference before and after former pipe mill rolled bands, effective restriction metal lateral flow, prevents deformable metal from flowing to roll gap, reduces and rolls card, rolling is stablized, for rolling thin-wall pipe provides advantage.

Detailed description of the invention
In Fig. 1 ~ 4: substitute disc guiding device with guide agency when light-wall pipe produced by the pipe mill be made up of guide plate, cone-shaped roll, plug, frame, the cone-shaped roll that little tail is large is arranged in the roller case of pipe mill main frame roll device, left and right is arranged, driven separately by direct current generator, two-dimentional adjustable all around; Upper and lower two pieces of arc-shaped guide plates are arranged on the upper and lower guide plate clamping device on upper and lower guide plate frame respectively, and upper and lower guide plate clamping device is for arrange up and down, adjustable up and down by front and back; Matched by left and right two cone-shaped rolls and upper and lower two pieces of guide plates and form a blind bore type space, by adjusting device adjustment pass size.Upper guide plate clamping device is for be provided with guide plate stay hook in side, upper guide plate frame bottom, and opposite side is provided with guide plate sliding hook, and upper guide plate is arranged between guide plate stay hook and guide plate sliding hook, and passes through nut check.Bottom guide clamping device is that the side, top of bottom guide frame is provided with guide plate stay hook, and opposite side is provided with guide plate sliding hook, and bottom guide is arranged between guide plate stay hook and guide plate sliding hook, and passes through nut check.The front portion of pipe mill guide plate longitudinal direction is approach cone, and rear portion is for going out prostomum, and approach cone and going out for compression strap between prostomum, flash and low limit are divided in the cross section of guide plate, and guide plate two ends are provided with the fixed block matched with guide plate clamping device.
The technological process of its light-wall pipe rolling is: raw material preparation → heating of pipe blank → roll piercing → tube rolling → sizing → cooling → aligning → Non-Destructive Testing → crop, tail → finished product inspection → spray mark → packaging → warehouse-in
The roll unit after the utility model is used to be made up of one " annular pass " the cone-shaped roll of two actives, guide plate fixing up and down and a long plug, roll shaft and roll line are interlaced arrangement, form two angles between the two in space: feed angle and roll off angle.Roll barrel by approach cone, wall-reducting section, smooth section and go out prostomum four sections and form.Corresponding deformed area is divided into sizing reduction section 16, wall-reducting section 15, expansion section 14 and expanding circular section 13 4 sections.Guide plate longitudinally by approach cone, compression strap, go out prostomum and form, corresponding with the related variation district of the cone-shaped roll body of roll.In the one end of the hollow billet that punch is sent here, after inserting long plug, the roll sent in pipe mill by pinch roll coordinates the pass space formed to be rolled with guide plate, and hollow billet rotates after nipping, successively by each section of deformed area, through tube reducing, subtract wall, expansion and expanding circle of returning and form hollow forging.
