Description

Bending guide rod straightener

Technical field

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

Background technology

Hot galvanized steel pipe manufacturing enterprise is in steel pipe's production process, the guide rod used often bends, cannot use after bending, need the guide rod more renewed or the guide rod changed is carried out straightening processing, the little existing straightening processing of guide rod of flexural deformation is mainly artificial straightening, precision is inadequate, and the bigger guide bar support of most of flexural deformation is scrapped.

Summary of the invention

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

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

Nipping roller segment, including a pair live-roller, guide rod enters bending guide rod straightener under the drive of roller segment of nipping;

Aligning plain-barreled roll part includes multiple horizontal smoothing roll, and aligning edger roll part includes multiple vertical smoothing roll; The axle of horizontal smoothing roll is mutually perpendicular to the axle of vertical smoothing roll, and guide rod is provided orthogonal extruding force to align by horizontal smoothing roll and vertical smoothing roll respectively;

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, including top roll and lower roll, the axial line of described top roll and lower roll forms 60 degree of angles, and top roll and lower roll form 30 degree of angles with guide rod respectively, and top roll linearly contacts with guide rod respectively with the roll surface of lower roll; Top roll and lower roll are the dolioform of roll surface indent;

Draw roll part, including a pair live-roller, by the guide rod output bending guide rod straightener after aligning.

There is horn mouth roller segment front end of nipping, it is simple to penetrated into by guide rod in the live-roller of 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 is from middle traverse, and the longitudinal stretching force being subject to and be laterally perpendicular to the active force of channel direction, thus being straightened by bending. Flattening precision and work efficiency have great raising.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described, as illustrated in fig. 1 and 2, bends guide rod straightener, include nip roller segment 1, aligning plain-barreled roll part 2, aligning edger roll part 3, smoothing roll part 4 and draw roll part 5 successively.

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

Aligning plain-barreled roll part 2, including five horizontal smoothing rolls, the axle level of horizontal smoothing roll is installed, and guide rod 8 is extruded in vertical direction and aligns. The rotation of horizontal smoothing roll is except having longitudinal frictional force that guide rod 8 also has the vertical of above-below direction guide rod 8, and guide rod 8 is started to straighten by this vertical in advancing repeatedly.

Aligning edger roll part 3, including five vertical smoothing rolls, the axle right angle setting of vertical smoothing roll, extrudes in the horizontal direction guide rod 8 and aligns. Vertical smoothing roll is passive rotation, guide rod 8 enters vertical smoothing roll, guide rod 8 makes vertical smoothing roll rotate by frictional force, guide rod 8 is in close contact with the roll surface of vertical smoothing roll, thus being subject to horizontal direction and being perpendicular to the active force of guide rod 8, guide rod 8 is straightened by this active force in advancing repeatedly further.

The roll surface of horizontal smoothing roll and vertical smoothing roll has the profile of the groove of arcs of recesses, groove shape and guide rod 8 to match. The both sides being distributed in guide rod 8 that horizontal smoothing roll and vertical smoothing roll are staggered respectively.

Smoothing roll part 4, including top roll 41 and lower roll 42, the axial line of described top roll 41 and lower roll 42 forms 60 degree of angles, and top roll 41 and lower roll 42 form 30 degree of angles with guide rod respectively, and top roll 41 linearly contacts with guide rod 8 respectively with the roll surface of lower roll 42; Lower roll 42 is active rotation, top roll 41 is passive rotation, and the force direction of guide rod 8 is become 30 degree of angles of cut when rotating around respective axial line by top roll 41 and lower roll 42, and this power can be decomposed into longitudinal force and vertical force, longitudinal force makes guide rod 8 move forward, and vertical force extruding guide rod 8 makes guide rod 8 straighten.

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

Draw roll part 5, including a pair live-roller, exports bending guide rod straightener by the guide rod 8 after aligning.

There is horn mouth 6 roller segment 1 front end of nipping, it is simple to penetrated into by guide rod 8 in the live-roller of roller segment 1 of nipping.

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