本考案は圧下スクリユーに横力が掛からないよ
うにした管圧延機のスクリユー横力防止用プレー
ト機構に関する。[Detailed Description of the Invention] The present invention relates to a screw lateral force prevention plate mechanism for a tube rolling mill that prevents lateral force from being applied to the rolling screw.

ーに横力が掛かり、ねじ部に変形、破損等の不具
合が生じるおそれがある。 For example, when the cradle is rotated in the horizontal direction to give a feed angle to the piercing roll, the reduction screw attached to the housing applies a lateral force to the screw, which is conventionally used to directly reduce the cradle, and the threaded portion of the reduction screw is rotated. Problems such as deformation and damage may occur.

徴とするものである。 This invention was developed with the aim of preventing lateral force from being applied to the reduction screw even when the cradle is rotated. It is characterized by the interposition of a pressure plate.
以下、本考案の実施例を図面に基づき説明す
る。 Hereinafter, embodiments of the present invention will be described based on the drawings.

１０上面に当接せしめる。 An upper cradle 6 with an upper piercing roll 5 rotatably pivoted thereon is suspended from the lower end of the piston rod 3 of the roll balance cylinder 2 attached to the housing 1 via the lower head 4.
A sector gear 7 is fixed to the side of the sector gear 7.
A rack 8 which can be rotated by a required drive device is engaged with the upper cradle 6 so that the upper cradle 6 can be rotated in the horizontal direction by the operation of the rack 8. The pressure plate 10 is placed on the pressure plate 10, and the block 11 is fixed at a predetermined position on the pressure plate 10 as shown in FIG. The shear plate 10 can be moved up and down but not rotated in the horizontal direction, and the lower end of the reduction screw 14, which can be moved up and down by a worm reducer 13 disposed in the housing 1, is brought into contact with the upper surface of the pressure plate 10. Let me touch you.
次に、本考案の作用について説明する。 Next, the operation of the present invention will be explained.
上ピアシングロール５にフイード角を与える場

動する。従つて圧下スクリユー１４には横力が掛
かることははい。 When giving a feed angle to the upper piercing roll 5, the rack 8 is operated to rotate the upper cradle 6 in the horizontal direction. Since the upper pressure plate 10 cannot be rotated in the horizontal direction, the upper cradle 6 rotates while sliding on the seat 9. Therefore, it is true that no lateral force is applied to the reduction screw 14.

え得ること、等は勿論である。 In addition, in the embodiment of the present invention, the case where the screw lateral force prevention plate mechanism is applied to a piercing mill has been explained, but it is also possible to apply it to an elongator, and it can be applied not only to the upper cradle side but also to the lower cradle side. can also be applied, and other
Of course, various changes may be made without departing from the gist of the present invention.
