Description
Technical field:
The utility model relates to rolling mill device in a kind of metallurgical industry, especially a kind of device of preventing deformed bars from bending.
Background technology:
In the prior art, the finished product screw-thread steel all has slight curved steel phenomenon, and this screw-thread steel presents the irregular crooked curved steel phenomenon that rises and falls along axis direction, and is particularly evident to the screw-thread steel of minor diameter specification.Though the curved steel phenomenon of screw-thread steel does not influence the serviceability of screw-thread steel, but, be screw-thread steel product appearance qualitative one big defective after all, this is that known technology does not have the problem that can solve, and also is the existing in prior technology weak point that screw-thread steel is produced.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and provide a kind of device technique scheme of preventing deformed bars from bending, this scheme adopts at the product outlet conduit of rolling mill and wears and installs coaxial vibrationproof clamper between the water pipe conduit additional, after screw-thread steel is come out by the product outlet conduit of rolling mill, directly enter the vibrationproof clamper, by enter again behind the vibrationproof clamper wear water pipe go the cooling, can make the finished product screw-thread steel eliminate curved steel phenomenon, guarantee the presentation quality of screw-thread steel product.
This programme is realized by following technical measures: include the product outlet conduit and have the water pipe of wearing of wearing the water pipe conduit, and two axial lines is coaxial, the characteristics of this programme are at described product outlet conduit and wear and have a clamper installation sleeve to be fixed on by support between the water pipe conduit to wear on the water pipe, the vibrationproof clamper of tape gripper entry conductor is housed, the axis of described vibrationproof clamper and described product outlet conduit and the axis coaxle of wearing water pipe on described clamper installation sleeve.The concrete characteristics of this programme also have, described vibrationproof clamper reverses frame, be connected with axis on the frame two side on the vertical plane of same vibrationproof clamper axis reversing, and identical last roll shaft and the lower roller shaft that is parallel to each other again of diameter, on the last roll shaft pinch upper roll is housed, the pinch under roll identical with pinch upper roll is housed on the lower roller shaft, and pinch upper roll and pinch under roll can be simultaneously tangent with vibrationproof clamper axis, and the described roll shaft of going up is connected with a roll spacing governor motion with lower roller shaft simultaneously.Described roll spacing governor motion is the same side at last roll shaft and lower roller shaft, eccentric last roll shaft adjusting gear is housed on the last roll shaft, the lower roller shaft adjusting gear identical with last roll shaft adjusting gear is housed on the lower roller shaft, last roll shaft adjusting gear is connected with a roll adjustment bar with the lower roller shaft adjusting gear simultaneously, last screw-threaded engagement on last roll shaft adjusting gear and the roll adjustment bar, following screw-threaded engagement on lower roller shaft adjusting gear and the roll adjustment bar, the rotation direction of last screw thread and following screw thread is opposite.The described other end of going up roll shaft and lower roller shaft respective roller distance regulating mechanism is contained in respectively in two identical excentric sleeves.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, at the product outlet conduit of rolling mill with wear and have a clamper installation sleeve to be fixed between the water pipe conduit to wear on the water pipe by support, the vibrationproof clamper of tape gripper entry conductor is housed, described vibrationproof clamper axis and described product outlet conduit and the axis coaxle of wearing water pipe on described clamper installation sleeve.This structure, screw-thread steel directly enter the vibrationproof clamper after being come out by the product outlet conduit of rolling mill, wear water pipe and go cooling by entering behind the vibrationproof clamper again.Screw-thread steel is when stretching out the product outlet conduit, also be in the high temperature after just rolling, very easily crooked, vibration when adding rolling mill work again, make and just will produce runout and shake through rolling screw-thread steel, it is crooked that this runout and shake can cause the screw-thread steel that is under the high temperature to produce, and just causes the curved steel phenomenon of finished product screw-thread steel again through cooling.Outside the product outlet conduit of existing rolling mill, install the described device of this programme additional, just can make firm rolling intact high temperature screw-thread steel give certain clamping and support through the vibrationproof clamper, runout and shake that screw-thread steel causes because of the rolling mill vibration have been prevented, do not have the high temperature screw-thread steel of runout and shake to wear long after the water pipe cooling, the screw-thread steel finished product of production has not just had curved steel phenomenon.And the vibrationproof clamper is to help screw-thread steel by upper and lower nip rolls, so double thread steel surface can not produce scuffing, has guaranteed the presentation quality of screw-thread steel finished product.In addition, the distance between two nip rolls can be regulated by the roll spacing governor motion, and this can adapt to the screw-thread steel of different size rolling again.This shows that the utility model compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 overlooks part sectional structure schematic diagram for vibrationproof clamper among Fig. 1.
Among the figure, 1 is the product outlet conduit, and 2 is the clamper entry conductor, and 3 is the clamper installation sleeve, 4 are the vibrationproof clamper, and 5 is last roll shaft adjusting gear, and 6 for reversing frame, 7 is the lower roller shaft adjusting gear, and 8 is lower roller shaft, and 9 is last roll shaft, 10 is pinch upper roll, and 11 is pinch under roll, and 12 is the roll adjustment bar, 13 is last screw thread, and 14 are following screw thread, and 15 is support, 16 for wearing the water pipe conduit, and 17 for wearing water pipe, and 18 is excentric sleeve.
