Abstract
The utility model relates to a pressing screw spherical device of a pressing type shape steel straightening machine, which prevents the local damage of trapezoidal threads for lifting as the upper end of a pressing screw bears the horizontal component force for straightening, thereby protecting the pressing screw and ensures normal pressing operation. The pressing screw spherical device comprises a straitening roll collar (1), a lower roll frame (2), a pressing device (3), a locknut (4), a pressing screw (5), a pressing nut (6), a spherical concave pad (7) and a spherical convex pad (8), and is characterized in that a pair of spherical pads, namely, the spherical concave pad (7) and the spherical convex pad (8), are additionally arranged at the connecting part of the upper end of the pressing screw (5) and the lower roll frame (2), thereby ensuring self-alignment of the lower roll frame and protecting the screw threads on the lower end of the pressing screw from being damaged. The horizontal component force on the upper end of the pressing screw is greatly reduced, and therefore, the bending is reduced, thereby protecting the threads on the lower end of the pressing screw from being locally damaged owing to the uneven force and ensuring normal pressing operation. The condition that the screw threads at the lower end of the pressing screw are easily damaged owing to the bending of the upper end of the pressing screw and the condition of getting stuck owning to pressing are avoided, the overhauling time is reduced.
Description
Technical field
The utility model relates to a kind of device that presses on the formula section straightener, and particularly a kind of formula section straightener that presses presses leading screw sphere device.
Background technology
The formula section straightener of pressing is used to align the long type material, makes section bar eliminate the inhomogeneities of curvature through alternating bending repeatedly.The design feature that presses the formula section straightener is that upper straightening roll is fixed, and smoothing roll presses separately under each, and as shown in Figure 1 and Figure 2, aligning collars 1 is placed on the lower roll frame 2 by parts in the middle of a series of, and lower roll frame 2 is connected with pressuring upper device 3 by pressing leading screw.Pressuring upper device and with lower roll frame coupling part partial sectional view as shown in Figure 3, press transmission and drive by worm screw and press nut 6 rotations, press the trapezoidal thread of nut 6 by endoporus and drive and press leading screw 5 liftings, and then realize pressing of lower roll.
In the existing structure, during aligning collars 1 on-line straightening shaped steel, because factors such as section straightener pass and section bar impact, the straightening force that the aligning collars passes to lower roll frame 2 has big horizontal direction component, pass to and press leading screw 5, pressing leading screw 5 upper ends and being connected to of lower roll frame 2 is rigidly connected, be subjected to big horizontal direction power so press leading screw 5 upper ends, cause and press leading screw 5 and bend, itself and press trapezoidal thread faying face unbalance stress between the nut 6, the easy local damage of screw thread presses stuckly, increases the site examining and repairing frequency.
Summary of the invention
The utility model has overcome the deficiency of above-mentioned technology; provide a kind of prevent to press leading screw since the upper end bear the aligning horizontal component cause lifting to press leading screw sphere device with the formula that the presses section straightener of trapezoidal thread local damage; thereby protection presses leading screw, guarantees normally to press.By aligning collars (1), lower roll frame (2), pressuring upper device (3), locking nut (4), press leading screw (5), press nut (6), the recessed pad of sphere (7), the protruding pad of sphere (8), sphere A (10), sphere B (11) form, it is characterized in that on pressing leading screw (5), setting up a pair of ball ring with lower roll frame (2) coupling part, be recessed pad of sphere (7) and the protruding pad of sphere (8), make lower roll frame (2) realize self-alignment, and then avoid pressing leading screw lower end thread damage.
Lower roll frame of the present utility model (2) is gone up and is pressed leading screw (5) junction and opens counterbore, the a pair of ball ring of addition in the counterbore, wherein the recessed pad of sphere (7) puts together on bolt in the counterbore of opening on the top roll frame, and the protruding pad of sphere (8) is placed in and presses on the boss of leading screw (5) upper end.The hole is all opened at the two center, in order to pass the upper end that presses leading screw (5).The spherical radius SR1 of the recessed pad of sphere (7) equates with the spherical radius SR2 value of the protruding pad of sphere (8).The aligning collars passes to the straightening force of lower roll frame (2); pass to the sphere B (11) of the protruding pad of sphere (8) by the sphere A (10) of the recessed pad of sphere (7); sphere is in conjunction with the purpose that reaches lower roll frame self-alignment; pressing the suffered horizontal component in leading screw upper end significantly reduces; bending reduces; thereby protect the screw thread of its lower end, avoid it, guarantee to press normal use because of the unbalance stress local damage.Avoided pressing leading screw since the stressed bending in upper end cause the lower end screw thread rapid wear, press stuckly, reduce the repair time.

The specific embodiment:
As shown in Figure 4, lower roll frame (2) is gone up and is pressed leading screw (5) junction and opens counterbore, a pair of ball ring of addition in the counterbore, and wherein the recessed pad of sphere (7) puts together on bolt in the counterbore of opening on the top roll frame, and the protruding pad of sphere (8) is placed in and presses on the boss of leading screw (5) upper end.The hole is all opened at the two center, in order to pass the upper end that presses leading screw (5).
As shown in Figure 5 and Figure 6, the spherical radius SR1 of the recessed pad of sphere (7) equates with the spherical radius SR2 value of the protruding pad of sphere (8).The aligning collars passes to the straightening force of lower roll frame (2); pass to the sphere B (11) of the protruding pad of sphere (8) by the sphere A (10) of the recessed pad of sphere (7); sphere is in conjunction with the purpose that reaches lower roll frame self-alignment; pressing the suffered horizontal component in leading screw upper end significantly reduces; bending reduces; thereby protect the screw thread of its lower end, avoid it, guarantee to press normal use because of the unbalance stress local damage.
