Abstract

The invention relates to a straightening device, in particular to a bent guide rod straightening device used in the production of a hot galvanized steel pipe. The device sequentially comprises a nip roller part, a straightening horizontal roller part, a straightening vertical roller part, a straightening roller part and a drawing roller part, wherein extrusion forces which are perpendicular to one another are respectively provided to the guide rod by the straightening horizontal roller part and the straightening vertical roller part so as to carry out straightening; the straightening roller part comprises an upper roller and a lower roller, an inclined angle of 60 degrees is formed by the axes of the upper roller and the lower roller, and an inclined angle of 30 degrees is formed respectively between the upper roller and the guide rod and between the lower roller and the guide rod. The bent guide rod is changed into a straight one by the bent guide rod straightening device provided by the invention in such a way that a straightening channel is formed by the three groups of straightening parts, the nip roller and the drawing roller, the guide rod penetrates through the straightening channel and is subjected to longitudinal drawing force and transverse action force perpendicular to the channel. Both the straightening precision and the work efficiency are greatly improved.

Description

Bending guide rod straightener

Technical field

The present invention relates to straightener, specifically the bending guide rod straightener in a kind of hot galvanized steel pipe production.

Background technology

Hot galvanized steel pipe manufacturing enterprise is in steel pipe's production process, the guide rod using is often bending, after bending, cannot use, the guide rod that need to more renew or the guide rod of changing is carried out to straightening processing, the little existing straightening processing of guide rod of flexural deformation is mainly artificial straightening, precision is inadequate, and the larger guide bar support of most of flexural deformation is scrapped.

Summary of the invention

For above-mentioned technical problem, the invention provides a kind of device that can accurately align guide rod, concrete technical scheme is:

A kind of bending guide rod straightener, comprises the roller segment of nipping, aligning plain-barreled roll part, aligning edger roll part, smoothing roll part and draw roll part successively;

The roller segment of nipping, comprises a pair of live-roller, and guide rod enters bending guide rod straightener under the drive of the roller segment of nipping;

Aligning plain-barreled roll part comprises multiple horizontal smoothing rolls, and aligning edger roll part comprises multiple vertical smoothing rolls; The axle of horizontal smoothing roll is mutually vertical with the axle of vertical smoothing roll, and horizontal smoothing roll provides orthogonal extruding force to align to guide rod respectively with vertical smoothing roll;

The roll surface of horizontal smoothing roll and vertical smoothing roll has the groove of arcs of recesses, and groove shape and guide rod match;

Smoothing roll part, comprises top roll and lower roll, and described top roll and the axial line of lower roll form 60 degree angles, and top roll and lower roll form 30 degree angles with guide rod respectively, and the roll surface of top roll and lower roll is linear with guide rod respectively and contacts; Top roll and lower roll are the dolioform of roll surface indent;

Draw roll part, comprises a pair of live-roller, and the guide rod after aligning is exported to bending guide rod straightener.

The roller segment front end of nipping has horn mouth, is convenient to guide rod to penetrate in the live-roller of the roller segment of nipping.

Aligning plain-barreled roll part directly has transition horn mouth with aligning edger roll part.

Bending guide rod straightener provided by the invention, is provided with three groups of aligning parts, nip roller and draw roll, forms an aligning passage, and guide rod passes from centre, the longitudinal stretching power being subject to and the horizontal active force perpendicular to channel direction, thus straightened by bending.Flattening precision and operating efficiency have great raising.

Brief description of the drawings

Fig. 1 is the main TV structure schematic diagram of bending guide rod straightener of the present invention;

Fig. 2 is bending guide rod straightener plan structure schematic diagram of the present invention;

Fig. 3 is smoothing roll part structure for amplifying schematic diagram of the present invention.

Detailed description of the invention

Below in conjunction with brief description of the drawings the specific embodiment of the present invention, as illustrated in fig. 1 and 2, bending guide rod straightener, comprises the roller segment 1 of nipping, aligning plain-barreled roll part 2, aligning edger roll part 3, smoothing roll part 4 and draw roll part 5 successively.

Wherein, the roller segment 1 of nipping, comprises a pair of live-roller, and guide rod 8 enters bending guide rod straightener under the drive of the roller segment of nipping.

Aligning plain-barreled roll part 2, comprises five horizontal smoothing rolls, and the axle level of horizontal smoothing roll is installed, and guide rod 8 is pushed and aligned in vertical direction.The rotation of horizontal smoothing roll is except having longitudinal frictional force also guide rod 8 to be had the vertical of above-below direction to guide rod 8, and guide rod 8 is repeatedly subject to this vertical in advancing and starts to straighten.

Aligning edger roll part 3, comprises five vertical smoothing rolls, and the axle at right angle setting of vertical smoothing roll, pushes and align in the horizontal direction guide rod 8.Vertical smoothing roll is passive rotation, guide rod 8 enters vertical smoothing roll, guide rod 8 rotates vertical smoothing roll by frictional force, the roll surface close contact of guide rod 8 and vertical smoothing roll, thereby the active force that is subject to horizontal direction vertical and guide rod 8, guide rod 8 is repeatedly subject to this active force in advancing and further straightens.

The roll surface of horizontal smoothing roll and vertical smoothing roll has the groove of arcs of recesses, and the profile of groove shape and guide rod 8 matches.The branch that horizontal smoothing roll interlocks respectively with vertical smoothing roll is in the both sides of guide rod 8.

Smoothing roll part 4, comprises top roll 41 and lower roll 42, and described top roll 41 and the axial line of lower roll 42 form 60 degree angles, and top roll 41 and lower roll 42 form 30 degree angles with guide rod respectively, and the roll surface of top roll 41 and lower roll 42 is linear with guide rod 8 respectively and contacts; Lower roll 42 is active rotation, top roll 41 is passive rotation, and top roll 41 becomes the 30 degree angles of cut to the force direction of guide rod 8 with lower roll 42 in the time that axial line rotates separately, and this power can be decomposed into longitudinal force and vertical force, longitudinal force moves forward guide rod 8, and vertical force extruding guide rod 8 straightens guide rod 8.

Top roll 41 and lower roll 42 are the dolioform of roll surface indent, two end faces that are top roll 41 and lower roll 42 are the circle that size is identical, roll surface is started gradually to axle center indent by two end faces, form the swelling-waist shape of eel-like figure, two end faces are connected with driving shaft, drive top roll 41 or lower roll 42 to rotate by drive unit.

Draw roll part 5, comprises a pair of live-roller, and the guide rod 8 after aligning is exported to bending guide rod straightener.

Roller segment 1 front end of nipping has horn mouth 6, is convenient to guide rod 8 to penetrate in the live-roller of the roller segment 1 of nipping.

Aligning plain-barreled roll part directly has transition horn mouth 7 with aligning edger roll part.
