Abstract
The utility model relates to a multi-track integral roll type twister for continuous rolling mills, which is composed of a frame, pressure screws, a bearing, a shaft rod, barrel twisters, a guide groove, a regulating wedge, etc. The multi-track integral roll type twister for continuous rolling mills is integrally arranged in a mill housing frame arranged at the lower side of a rolling mill. To accommodate requirements of the rolling stocks with different cross-sections, the radial directions and the axial dimensions of the two barrel twisters can be respectively regulated by the pressure screws and the regulating wedge, and the bearing and oil lubrication are arranged between the barrel twister and the shaft rod. The utility model has the advantages of small friction coefficient and big bearing torque.
Description
The utility model relates to a kind of tandem mill with whole roll-type twister, is specially adapted on the horizontal tandem mill of rolling big section rolled piece.Have simple in structure, characteristics such as adjustment is flexible, widely applicable, stable and reliable operation.
When the rolled piece of horizontal tandem mill entered next rolling mill from elliptic jet, if next rolling mill remains horizontally disposed, rolled piece must reverse 90 ° of angles, and twister is exactly a kind of equipment of realizing this function.Before the utility model was made, being used for twister on the tandem mill roughly had two kinds of the whole and multi-thread monomer-types of single line.Wherein, the former generally only is used on the single line tandem mill, and the not single applicable surface of this twister is narrow, and it can only be installed in outside the memorial archway of milling train downside, and is far away apart from the roll center line, thus rolled piece to begin windup-degree big, distortion is violent.Because it adopts resin tile bearing and water lubrication, so coefficient of friction is big, windup-degree is wayward in addition.
The monomer twister generally is used for the shaped steel and the rod-rolling mill of multistrand rolling, on the outlet crossbeam of milling train, several twisters are installed side by side, its major defect is: when disposing multi-thread groove rolling on the roughing mill roll, because of the rolled piece basal area bigger, the required space of the less installation twister of pass centre-to-centre spacing is often not enough, because of the moment of torsion that is born is bigger, torsion roller is easily loosening, even production accident occurs simultaneously.
The common feature of above-mentioned two kinds of twisters is twister line rolled pieces to milling train, and unfavorable integral body is control and operation automatically.
Tandem mill of the present utility model is made for the shortcoming that overcomes above-mentioned two kinds of twisters with multi-thread whole roll-type twister.This twister carries the guide groove framework, and integral installation is in the memorial archway of milling train downside, thereby its existing function of reversing rolled piece, and guide groove itself plays the effect that plate and twister entrance guide plate are defended in the milling train outlet again.The torsion roller section of whole roll-type twister is " square tooth " shape, and the number of teeth is more than 3, and the α value of its tooth stress surface is between 30 °～50 °.In order to adapt to the requirement of different section rolled piece, the top roll of twister can by housing screw radially (up and down) adjust, its axially (about) direction then adjusts by the wedge that screw rod drives.Select rolling bearing and oil lubrication up and down between two torsion rollers and axostylus axostyle for use, coefficient of friction is little, and is easy to adjust flexible.
Above-mentioned functions accompanying drawings of the present utility model is as follows:
Accompanying drawing has the front view and the vertical view of twister.Tandem mill is made up of framework (1), housing screw (2), bearing (3), axostylus axostyle (4), torsion roller (5), guide groove (6), wedge (7) etc. with multi-thread roll-type twister.This twister is vertically mounted in the memorial archway frame of milling train back, when rolling from roll later, rolled piece imports the slot of torsion roller (5) by guide groove (6), because upper and lower torsion roller is transferred to suitable gap by the shape and the size of rolled piece in advance, thereby lean on the effect of the tooth peak sidewall of torsion roller, rolled piece is turned round required angle.When changing the rolled piece cross dimensions, need to adjust the relative position of torsion roller up and down, its radially (up and down) size can finish by housing screw (2), axially (about) wedge (7) of the then reliable screw rod drive of size pushes axostylus axostyle and realizes.Whole device adjustment is flexible, and applicability is strong, is convenient to integral replacing.
Claims (6)
1, a kind of tandem mill is with multi-thread whole roll-type twister, it is characterized in that it is made up of framework (1), housing screw (2), bearing (3), axostylus axostyle (4), torsion roller (5), guide groove (6) and wedge (7) etc.
2, tandem mill according to claim 1 is with multi-thread whole roll-type twister, and the number of teeth that it is characterized in that torsion roller (5) is more than 3, and the α value of tooth stress surface is between 35 °～55 °.
3, tandem mill according to claim 1 is with multi-thread whole roll-type twister, and the housing screw (2) that it is characterized in that radially adjusting torsion roller (5) is installed on self framework (1).
4, tandem mill according to claim 1 it is characterized in that coming the axial adjustment torsion roller with wedge (7), and wedge carries the turn screw rod with multi-thread whole roll-type twister.
5, tandem mill according to claim 1 is characterized in that adapted bearing (3) and oil lubrication between torsion roller and axostylus axostyle with multi-thread whole roll-type twister.
6, tandem mill according to claim 1 is characterized in that with multi-thread whole roll-type twister its integral installation is in the memorial archway frame of milling train downside.
